This application claims priority from German Patent Application 10 2023 108 359.7, filed Mar. 31, 2023, which is incorporated herein by reference as if fully set forth.
The invention relates to a thermally insulating structural element, a building portion, and a method for installing a thermally insulating structural element on a construction site.
The use of thermally insulating structural elements, in particular in high structures, is adequately known in the prior art. Such structural elements are, for example, inserted between a building portion and a protruding element on the building portion and for thermal insulation between two cast building portions, for example, between a wall and a ceiling or a floor of a building. In addition to the thermal insulation, an object of the thermally insulating structural elements is also to form a connection between the two building portions by means of reinforcement elements in order to be able to take up and discharge specific loads.
EP 2 455 556 B1 thus discloses, for example, a correspondingly pressure-force-transmitting connection element for pressure-force-transmitting connection of a first cast component to a second cast component, wherein the connection element has an insulation member for thermally separating the two components and at least one pressure element and means for transverse force transmission.
EP 3 296 476 A1 discloses, for example, a form block for arranging between a building wall and a base or cover plate, wherein the form block is formed from concrete material and has a plurality of insulation member portions which are arranged substantially parallel with and between contact and support surfaces of the building wall or the floor or ceiling plates.
The above-mentioned thermally insulating structural elements are in particular used when different thermal conditions are acting on the individual building portions.
The above-mentioned thermally insulating structural elements are in most cases arranged accordingly on the construction site relative to the building portions before they are mostly cast with concrete in order to form their corresponding shape. Alternatively, the thermally insulating structural elements may also already be part of a prefabricated plate or a prefabricated component which is accordingly arranged on the construction site and then connected to the additional building portion, again by pouring out the building portion or a part thereof with a pourable material, in particular concrete. The arrangement and the position of the thermal structural element with respect to other building portions is dependent on different factors, in particular the thickness of a building portion or the concreting of a building portion. The relative position of the thermally insulating structural element is therefore often intended to be adapted to the individual local circumstances and conditions. To this end, the insulation member is placed, for example, in accordance with the ceiling thickness which is intended to be produced, and for positional fixing secured to reinforcement elements of the building portions or to auxiliary means until a secure connection is achieved between the building portion and structural element by means of the concreting of the building portion. Another significant aspect in this instance is that the reinforcement rods in the thermally insulating structural element are bonded accordingly in the building portions and after hardening of the cast building portion are anchored therein. It is thereby ensured that corresponding pressure and/or tensile forces between the individual building portions can also be safely transmitted and discharged. This is ensured by means of a corresponding bond length of the reinforcement elements in the cast components.
However, it has been found that the correct arrangement of the thermally insulating structural elements, in particular an arrangement in the correct position, is often difficult since the thermally insulating structural element prior to the concreting cannot be secured in a positionally stable manner to the reinforcement elements of the building portions or to auxiliary means. In addition, the bond length is not always constructed in the same manner and is dependent on different factors. Particularly when, for example, the thermally insulating structural element is intended to be positioned on a ceiling and a portion of a wall element is intended to be formed above the thermally insulating structural element, in particular a building wall or a parapet, the bond length of the reinforcement rods must be adapted individually since, for example, the ceiling on which the thermally insulating structural element is positioned has occurrences of unevenness. Without an adaptation of the bond length of the reinforcement rods, the thermally insulating structural element would, for example, as a result of occurrences of unevenness, be positioned obliquely on the ceiling, whereby thermal bridges can be formed with correspondingly negative thermal properties. In addition, during casting of the component, there may be a movement of the structural element, whereby it no longer remains in the desired position and, for example, tilts. In addition, with an excessively short bond length forces acting on the component can no longer be reliably discharged.
However, the adaptation of the bond length is possible with the thermally insulating structural elements from the prior art only by means of corresponding cutting of the reinforcement rods, for example, locally at the construction site or in the prefabrication plant since they are arranged securely in the insulation member of the thermally insulating structural element. A selective and secure and adaptable positional arrangement of the thermally insulating structural element is not known.
An object of the present invention is therefore to provide a thermally insulating structural element, a building portion and a method for installing a thermally insulating structural element which enables a simple adaptation of the bond length and an adjustability of the reinforcement elements of the thermally insulating structural element, in particular for adapting the position of the thermally insulating structural element.
An object of the present invention is further to provide a thermally insulating structural element, a building portion and a method for installing a thermally insulating structural element, by means of which at the same time a minimum bond length is ensured in order to comply with safety standards.
These above-mentioned objectives and other objectives are achieved with a thermally insulating structural element, a building portion, and a method for installing a thermally insulating structural element having one or more of the features described herein.
Advantageous embodiments of the thermally insulating structural element are described below and in the claims. Other advantageous embodiments of the building portion are described below and in the claims. Other advantageous embodiments of the method are also described below and in the claims.
The thermally insulating structural element according to the invention between two cast building portions, in particular between a wall and a floor or a ceiling, comprises at least one insulation member which is intended to be arranged between the building portions and at least one reinforcement element, wherein the at least one reinforcement element is in the form of an at least partially rust-resistant reinforcement rod which in the installed state extends in an extent direction substantially transversely to a longitudinal extent of the insulation member through the insulation member and is preferably constructed to be bonded in both building portions.
With the structural element according to the invention, the significant aspect is that the at least one reinforcement rod is arranged so as to be adjustable substantially in the extent direction within the structural element.
As a result of an adjustable arrangement within the structural element, the reinforcement rod can accordingly be adapted to the conditions in situ so that the thermally insulating structural element can be orientated directly at the construction site. Thus, as a result of the at least one movement rod which is arranged so as to be adjustable in the extent direction, the position of the insulation member with respect to the building portions can be adjusted and orientated accordingly. In particular, as a result of the adjustable arrangement of the at least one reinforcement rod, it can be adjusted in such a manner that, for example, it can be adapted with respect to occurrences of unevenness on the element which is intended to be placed or relative to the arrangement of other reinforcement members.
A preferred embodiment is characterized in that, in addition to the at least one reinforcement rod, at least one pressure-force-transmitting element is arranged so as to extend through the insulation member. The pressure-force-transmitting element preferably at least partially comprises a cast material. Advantageously, the at least one pressure-force-transmitting element has end faces which serve to introduce pressure force and which are constructed to preferably protrude over the insulation member in the extent direction. The end faces are in contact with the building portions and enable a transmission of pressure forces between the building portions.
In a preferred embodiment, the at least one reinforcement rod is arranged so as to be movable substantially in the extent direction. As a result of a movable arrangement of the reinforcement rod, it can now be displaced relative to the insulation member of the thermally insulating structural element and placed without in this instance having to change the length of the reinforcement rod. Consequently, in a simple manner, a bond length of the reinforcement rod at one side of the insulation member can be changed, whereby the reinforcement rod at the other side of the insulation member can accordingly be constructed to protrude to a greater or lesser extent into the second building portion.
Alternatively or preferably additionally, the reinforcement rod can be adjusted in increments or in a stepless manner. An adjustment of the reinforcement rod in increments enables a stepped reduction or increase of the bond length in the corresponding building portion, wherein, as a result of the stepped adjustment the bond length can be adjusted and sized in accordance with the individual increment steps. A stepless adjustability of the at least one movement rod increases the flexibility in the adaptation of the bond length, whereby the reinforcement rod and in particular the bond length of the reinforcement rod in the building portion can be adapted to almost any shape, any structural space or any environmental condition.
An advantageous embodiment of the structural element is characterized in that the at least one reinforcement rod at least partially has a profiling. In particular, the profiling may be an outer thread, a locking element and/or a thickened portion. As a result of the profiling, the adjustment range of the reinforcement rod can be indicated. In addition, the profiling may also be useful in enabling a precise adjustment of the reinforcement rod and the bond length thereof.
Preferably, the at least one reinforcement rod has at least two different profilings. In this instance, for example, it may be an outer thread having different pitches, different locking elements and/or different types of thicknesses in the reinforcement rod or on the reinforcement rod. As a result of corresponding profiling, different functions can be associated with the reinforcement rod. Additional ways of anchoring the reinforcement rod with the building portion can also be achieved with different profiles in the reinforcement rod or on the reinforcement rod.
In a preferred embodiment, the thermally insulating structural element comprises at least one adjustment device for adjusting the at least one reinforcement rod, wherein the adjustment device has one or more components. The adjustment device enables, in addition to a selective movement or adjustment of the reinforcement rod, a limitation of the maximum adjustability, whereby, for example, the reinforcement rod can be prevented from being pulled out of the insulation member.
In a preferred embodiment, at least one component of the adjustment device surrounds the reinforcement rod in parts at least partially. In particular, the at least one component of the adjustment device surrounds the reinforcement rod in parts completely. A component of the adjustment device is consequently arranged on the reinforcement rod itself and cooperates directly therewith. Consequently, it can be ensured that the adjustment device also has an influence directly on the reinforcement rod and the adjustment thereof. In particular, the component which at least partially surrounds the reinforcement rod in parts is an independent element, whereby the production of the reinforcement rod and the component is simplified.
In yet another preferred embodiment, at least one component of the adjustment device is constructed to be able to be connected to the reinforcement rod, in particular by means of clip-fitting, locking, insertion, adhesive-bonding, pressing and/or welding. In particular, the at least one component of the adjustment device may be formed by means of a clip, a ring, a thickened portion and/or a sleeve. The at least one component of the adjustment device can consequently be applied thereto in different manners, depending on the reinforcement rod used. The connection method may in this instance in particular be dependent on which forces are acting on the reinforcement rod when the reinforcement rod is installed or when the thermally insulating structural element is used. In addition, a high level of safety and reliability of the adjustment device is intended to be ensured.
Preferably, the adjustment device, in particular a component of the adjustment device, has a counter-profile which is constructed to cooperate with the profiling of the reinforcement rod for adjustment. In particular, the counter-profile is formed by means of at least one portion of an inner thread, at least one clamp and/or at least one additional locking element. As a result of the profiling acting as one component and the counter-profile acting as another component, the adjustment of the reinforcement rod can be carried out in a precise manner and at the same time a slipping of the positioning of the reinforcement rod can be prevented.
In a preferred embodiment, the counter-profile is constructed in the insulation member itself. Consequently, the insulation member itself has the corresponding counter-profile and requires no additional component to form the counter-profile.
Preferably, the reinforcement rod has an adjustment range. As a result of the adjustment range, the reinforcement rod can be moved in a predetermined range so that, for example, a minimum bond length in a building portion is ensured and the reinforcement rod can be prevented from being pulled out.
Advantageously, the adjustment range of the reinforcement rod is in the range from 0.5 cm to 50 cm, preferably from 1 cm to 20 cm, in a particularly preferred manner from 2 cm to 12 cm. The reinforcement rod can consequently move as a result of the limitation means only within a predetermined range, wherein the range may also be constructed differently depending on the respective application area and field of use of the thermally insulating structural element.
A preferred embodiment is characterized in that the adjustment device has at least one limitation means in order to form the adjustment range. In particular, the limitation means has one or more components of the adjustment device. As a result of the limitation means, the adjustability, in particular the movement radius and movement space of the movement rod can be limited. It is thereby particularly possible to prevent the reinforcement rod from being able to be removed from the insulation member and at the same time a minimum bond length in the cast component is ensured. As a result of the limitation means, the reinforcement rod is limited in terms of its movability and can be moved only within the adjustment range.
In a preferred embodiment, the limitation means is arranged outside and/or inside the insulation member. A limitation means outside the insulation member, for example, a clip or ring, can be fitted in a simple and rapid manner. The limitation means may also be formed inside the insulation member. This has the advantage that it is ensured that the limitation means, in contrast to limitation means which are arranged outside the insulation member, cannot be unintentionally removed or fall away.
Alternatively or preferably additionally, a plurality of limitation means are arranged in the extent direction along the reinforcement rod. As a result of a plurality of limitation means, the movability of the reinforcement rod both in an extent direction and counter to the extent direction can be limited. In particular, precisely two limitation means which are preferably arranged with respect to a center axis of the longitudinal extent of the insulation member at both sides of the center axis are used.
In another preferred embodiment, the limitation means has at least one stop and a stop face or a stop location. As a result of the stopping action with the stop face or the stop location, a fixed end of the adjustment range, which must not be exceeded, is predetermined in order, for example, to ensure a minimum bond length of the reinforcement rod in one direction. The stop face or the stop location may, for example, be formed by the insulation member itself, whereas the stop is, for example, in the form of a ring on the reinforcement rod. Preferably, the stop face or the stop location may be located on an outer face of the insulation member or be formed inside the insulation member.
Alternatively or preferably additionally, the limitation means is an end sleeve in which the reinforcement rod can be introduced, in particular screwed in or locked in. The end sleeve which is connected to the reinforcement rod serves, on the one hand, to limit the movability of the reinforcement rod and can, on the other hand, form an adjustable means which enables an adjustment of the bond length by means of rotation or locking of the reinforcement rod in the end sleeve. The reinforcement rod can thus be adapted to the conditions locally at the construction site.
A preferred embodiment is characterized in that the adjustment device, in particular the components thereof, are formed at least partially, in particular completely, from plastics material. The plastics material is preferably a thermoplastic plastics material. Components made of plastics material can be readily produced, in particular by means of injection-molding, wherein a large number of different shapes and configurations is possible. The component of the adjustment device can thereby be accordingly formed so as to be adapted to the reinforcement rod and the thermally insulating structural element. Alternatively, the adjustment device or the components thereof can also be produced using a 3D printing method. Individual components can thereby be produced in a selective and accordingly adapted manner.
Alternatively or preferably additionally, the adjustment device has a guide, in which at least one component of the adjustment device is movably arranged. Alternatively or preferably additionally, the adjustment device has as the component a rod guide as the guide in which the reinforcement rod is guided. The guiding ensures that the reinforcement rod is movably arranged in particular only in the extent direction. An incorrect orientation of the reinforcement rod during installation, by means of which the load absorption can change accordingly, is thereby prevented. Particularly when the guide and limitation means cooperate, the guide may also at the same time form or have a stop or stop face or a stop location for the limitation means. A selective guiding of the reinforcement rod and at the same time the limitation of the movability of the reinforcement rod is thereby enabled in a simple manner.
In another preferred embodiment, the structural element comprises a plurality of reinforcement rods, wherein at least some of the reinforcement rods, preferably all of the reinforcement rods, of the structural element can be adjusted. The thermally insulating structural element can consequently be formed from reinforcement rods which all enable an adjustability. Alternatively, only some of the reinforcement rods of the structural element may also be constructed in an adjustable manner. In an exemplary embodiment, for example, only reinforcement rods which are arranged in the region of the outer edges of the insulation member may have an adjustability, whereas reinforcement rods in the interior, in a state distributed over the length of the insulation member, are not adjustable. The non-adjustable reinforcement rods should in this instance preferably be constructed in such a manner that they protrude only with the minimum bond length over the insulation member so that the structural element comprising adjustable and non-adjustable reinforcement rods can nonetheless be used in a flexible manner and adapted accordingly to the conditions in situ.
An adjustability of all the reinforcement rods of the structural element increases the flexibility of the thermally insulating structural element, whereby it can be adapted to almost any external peripheral condition and accordingly adjusted.
Alternatively or preferably additionally, the reinforcement rod is formed from a fiber-reinforced material, preferably from a fiber-reinforced plastics material. In particular, the fiber-reinforced material is a glass-fiber composite material. Reinforcement rods made of fiber-reinforced material are, on the one hand, lightweight and have, on the other hand, a high level of stability with at the same time optimum force transmission. In addition, the reinforcement rods made of fiber-reinforced material are available in different forms. In addition, with reinforcement rods made of fiber-reinforced material, during production the outer form can be constructed in a simple manner in accordance with provisions so that, for example, one or more profilings can be formed in the reinforcement rod.
A preferred embodiment of the thermally insulating structural element is characterized in that the reinforcement rod has at least one, preferably a plurality of desired breaking locations. In particular, the reinforcement rod can be adjusted in terms of its length by separation at the desired breaking location. By means of desired breaking locations, the reinforcement rod can be changed in terms of its bond length in increments or in a stepped manner without a movable arrangement of the reinforcement rod within the insulation member necessarily being required for this. Naturally, it is also within the scope of the present invention that the reinforcement rod is movable arranged within the insulation member and at the same time additionally has desired breaking locations which provide an additional adjustment possibility. It is thus, for example, possible with a parapet as a building portion to change the length of the reinforcement rod and to adapt it to the height of the corresponding parapet.
In yet another preferred embodiment, there is arranged on the at least one reinforcement rod, at one of the ends thereof or in the region of at least one end, at least one anchoring means for anchoring the reinforcement rod in at least one building portion or an auxiliary construction in order to produce the building portion during the construction phase. In particular, the anchoring means is constructed to cooperate with a receiving member in the building portion or the auxiliary construction. As a result of the anchoring means, the at least one reinforcement rod can be selectively connected to the corresponding building portion or the auxiliary construction in order to produce the building portion during the construction phase. The auxiliary construction is preferably a formwork panel, for example, a formwork floor. In a particularly advantageous manner, it is thereby possible for the reinforcement rod to be able to be connected to the building portion already prior to the definitive casting of the corresponding building portion. It is thereby particularly ensured that a movement of the reinforcement rod when casting the building portion is prevented.
As another solution to the above-mentioned objectives, a building portion which comprises at least two cast building portions, in particular a wall and a floor or a ceiling is set out. The building portion according to the invention is characterized in that a thermally insulating structural element or a preferred embodiment thereof, as set out above, is arranged between the building portions.
In a preferred embodiment of the building portion, the thermally insulating structural element is arranged above a building portion. In particular, the thermally insulating structural element and the building portions are arranged in layers one above the other and the at least one reinforcement rod extends substantially in a vertical direction. As a result of this arrangement, in particular the connection between a wall and a floor or a ceiling is possible. In particular, the layered construction comprising building portions and intermediate thermally insulating structural element is used in order to form a parapet or a fascia.
Alternatively or preferably additionally, the thermally insulating structural element is arranged beside a building portion. In particular, the thermally insulating structural element and the building portions are arranged beside each other, and the at least one reinforcement rod extends substantially in a horizontal direction. The extent direction of the reinforcement rod consequently coincides substantially with the horizontal direction. The above-mentioned structure is in particular used to connect a ceiling element to a wall element, wherein the reinforcement rod does not necessarily have to completely penetrate through the wall element and in particular can terminate in the wall element. Preferably, the wall element comprises one or more receiving members for anchoring means in which the anchoring means can engage on the reinforcement rods.
Another preferred embodiment of the building portion is characterized in that the at least one reinforcement rod has an anchoring means and in that a building portion, in particular a wall or a ceiling, has at least one receiving member for the anchoring means. Consequently, the reinforcement rod can be selectively anchored in the building portion, wherein the receiving member is constructed to correspond to the anchoring means.
Alternatively or preferably additionally, there may also be arranged on the building portion and/or in the building portion anchoring means in which the reinforcement rods can engage for anchoring and connection.
Furthermore alternatively or preferably additionally, there may also be arranged on an auxiliary construction in order to produce a building portion during the construction phase one or more receiving members and/or one or more anchoring devices, in which the reinforcement rods can engage for temporary anchoring and connection.
As yet another solution, a method for installing a thermally insulating structural element between two building portions on a construction site is set out. A significant aspect for the method is that the thermally insulating structural element or a preferred embodiment thereof, as set out above, is used and at least one reinforcement rod prior to installation between the building portions or after an arrangement of the structural element between the building portions is adjusted to a specific dimension.
A preferred embodiment of the method is characterized in that the thermally insulating structural element is additionally fixed after the adjustment of the at least one reinforcement rod and subsequently a concreting operation is carried out. In particular, there is brought about a fixing to the reinforcement elements of the building portions and/or to an auxiliary construction. As a result of the fixing, in particular floating of the thermally insulating structural element during the concreting operation is intended to be prevented.
In another advantageous embodiment, during the method the thermally insulating structural element with the previously adjusted, at least one reinforcement rod is inserted or pressed into the fresh concrete only directly after the concreting of the first building portion. It is thereby possible, for example, for a fixing of the thermally insulating structural element to be dispensed with.
In yet another preferred embodiment of the method, the at least one adjustable reinforcement rod of the thermally insulating structural element is arranged in abutment against a formwork or a semi-finished product and a position of the insulation member of the thermally insulating structural element relative to a building portion is adjusted to a dimension by adjusting the at least one adjustable reinforcement rod. The position of the thermally insulating structural element or the insulation member of the thermally insulating structural element can consequently be directly adapted by the at least one adjustable reinforcement rod, for example, to the thickness of the building portion, wherein the thermally insulating structural element is fixed in position and stabilized in terms of position as a result of the abutting arrangement on the formwork or the semi-finished product.
Other preferred embodiments of the thermally insulating structural element, the building portion or the method for installing a thermally insulating structural element on a construction site are explained and described in greater detail below with reference to the drawings.
In the drawings:
The reinforcement rods 3, 3′ extend, as illustrated in
The insulation member 2 is in this instance a pressure-stable plastics material which is constructed integrally or from a plurality of individual elements and assembled accordingly. The structure of the individual elements may relate both to the longitudinal extent of the insulation member 2 in the longitudinal direction 16 and a transverse extent of the insulation member 2 in the transverse direction 17. The insulation member 2 may be formed from a plurality of member elements in the transverse direction 17 or be constructed in an integral manner. Terminal elements may be arranged in each case on the sides faces 2a. Alternatively, the insulation member 2 may also be one or more dimensionally stable cases, for example, hollow cases made of a plastics material, which are filled at the inner side with an insulating material, for example, mineral wool.
In addition to the reinforcement rods 3, 3′, pressure-force-transmitting elements 3a are also arranged in the insulation member 2. The pressure-force-transmitting elements 3a are in this instance thrust bearings which protrude in the extent direction 13 laterally over the insulation member 2, in this instance over the abutment faces 2c. Over the longitudinal extent of the insulation member 2 in the longitudinal direction 16, a plurality of pressure-force-transmitting elements 3a are arranged in a state distributed with spacings. In addition, in the transverse direction 17, two pressure-force-transmitting elements 3a are arranged one above the other in each case. Alternatively, in the transverse direction 17, only one pressure-force-transmitting element 3a may also be arranged. The number and arrangement of the pressure-force-transmitting elements 3a is in particular dependent on the respective application area or field of use of the structural element 1 and the forces which are intended to be transmitted and forces acting on the structural element 1.
The insulation member 2 accordingly has for the reinforcement rods 3, 3′ recesses through which the reinforcement rods 3, 3′ extend. Some of the reinforcement rods 3 which are illustrated in
In some of the recesses in the insulation member 2, in which the movable reinforcement elements are arranged in the form of reinforcement rods 2, there are additionally arranged adjustment devices 5 which are constructed to cooperate with the reinforcement rod 3 according to the invention, as shown in
The arrangement and number of the adjustment device 5 within the thermally insulating structural element 1 are also dependent on the respective application area or field of use of the structural element 1 and the forces which are intended to be transmitted and the forces acting on the structural element 1. In particular, reinforcement rods 3, 3′ in the thermally insulating structural element 1 may be constructed differently or have different functionalities. In the insulation member 2, non-movable reinforcement rods 3′ are not coupled to an adjustment device 5 and therefore in most cases have a shorter length when viewed in the extent direction 13 than the reinforcement rods 3 in the edge region of the thermally insulating structural element 1 which cooperate with the adjustment device 5. As a result of the combination of non-movable reinforcement rods 3′ and movable reinforcement rods 3, a reliable force transmission is ensured, wherein, as a result of the shorter length of the non-movable reinforcement rods 3′, it is ensured that the structural elements can be adapted in a flexible manner to the environmental conditions.
The thermally insulating structural element 1 is installed between two cast building portions 21, 22 in a building portion 20. In
In
A first component 6 of the adjustment device 5 is formed by means of a clip which is permanently connected releasably to a reinforcement rod 3 by pressing the reinforcement rod 3 into the clip illustrated as the component 6. The clip as the component 6 has a plurality of ribs 6a which are arranged in a state uniformly distributed over the length of the clip. The ribs 6a are combined on a continuous web 6b, which web 6b is opposite the opening 6c of the clip in order to press in the reinforcement rod 3.
With or after the clip-fitting of the reinforcement rod 3 into the component 6, the reinforcement rod 3 is engaged or placed in the additional components 7, 7′ on the outer region of the adjustment device 5, whereby the reinforcement rod 3 (not illustrated) is supported in a state guided inside the adjustment device 5. By clip-fitting in the reinforcement rod 3 into the adjustment device 5, the clip is guided as the component 6 within a guide 11 which connects the two components 7, 7′. The reinforcement rod 3 can additionally be moved inside the guide 11 after connection to the component 6. The guide 11 substantially comprises narrow webs 11a, which extend in the extent direction 12. At each of the two sides of the extent direction 13 there is formed a stop 10 which limits the movability of the reinforcement rod 3. The stop 10 is again directly connected to the component 7, 7′ of the adjustment device 5.
The adjustment device 5 further has fixing means 14 by way of which they can be anchored in the insulation member 2 and accordingly fixed in position in the insulation member 2. The fixing means 14 are formed in this instance as continuations to the stop 10 and additionally also arranged on the webs 11a of the guide 11.
The movement of the reinforcement rod 3 is limited by the stops 10 in such a manner that it can be moved freely within an adjustment range 12 and can be adjusted in accordance with the requirements and conditions in situ. The component 6 and the guide 11 with the stop 10 together form a limitation means 9 which accordingly limits the movement of the reinforcement rod 3 in or counter to the extent direction 13.
If a force which exceeds a retention force is applied to the reinforcement rod 3 bearing on the stop 10, the component 6 can also be displaced relative to the reinforcement rod 3. This is inter alia possible in that the clip as the component 6 is releasably secured to the reinforcement rod 3 and consequently, when the retention force is exceeded, can also still be displaced along the reinforcement rod 3. In this embodiment, consequently, a movement of the reinforcement rod 3 beyond the actual adjustment range 12 is also possible, but only with a significantly higher force being applied with respect to the displacement within the adjustment range 12.
In the components 7, 7′ of the adjustment device 5 there is further formed a counter-profile 8 which is constructed to correspond to the profiling 4 of the reinforcement rod 3. The counter-profile 8 is in this instance in the form of a part-portion of a helical path. The profiling 4 of the reinforcement rod 3 and the counter-profile 8 consequently merge into each other and enable in this instance according to the embodiment illustrated an adjustment of the reinforcement rod 3 in an extent direction 13 by rotating the reinforcement rod 3 about its own axis. As a result of this shape, the position of the reinforcement rod 3 within the adjustment device 5 and consequently also within the thermally insulating structural element 1 can be precisely adapted to the conditions. In
In contrast to
The adjustment device 5 further has anchoring elements 14 which are arranged in an extent direction 13 at the side of the guide 11 and on the webs 11a. With the anchoring elements 14, the adjustment device 5 is fixed in the insulation member 2 so that it is arranged in a fixed manner in the insulation member 2. Consequently, a movement of the adjustment device 5 in the insulation member 2 can also be prevented within the adjustment device 5 when the reinforcement rod 3 moves.
The reinforcement rod 3 illustrated in
For anchoring in a building portion 21, 22, at one end of the reinforcement rod 3 and in each of the building portions 21, 22 there may be arranged an anchoring means, by way of which the reinforcement rod 3 can be fixed in a selective manner in the building portion 21, 22. The anchoring means may be constructed in such a manner that the reinforcement rod 3 can be rotated therein in order, for example, to shorten the length of the reinforcement rod 3 in the extent direction 13. The anchoring means may in particular be constructed to cooperate with a receiving member in one of the building portions 21, 22 in order to achieve the desired anchoring.
