The present invention relates to a framework support, which can be used to build a framework, in particular a scaffolding, a formwork structure or another support structure.
From DE 197 05 805 A1 a framework support that can be used as a ceiling formwork support is known, which is constructed with two U-shaped profile supports. The two profile supports are positioned facing each other with their profile webs connecting the respective profile legs and are inseparably connected to one another by spacer elements positioned between the profile supports and firmly connected to them by welding, as well as by spacer elements welded to profile support side surfaces formed in the region of the profile legs.
DE 10 2016 205 605 A1 discloses a framework support with two U-shaped profile supports, which are formed integrally with one another by bending a metal sheet into a shape providing the two profile supports and are therefore inseparably connected to one another.
It is the object of the present invention to provide a framework support which is easy to handle while having a simple structure and high versatility in use.
According to the invention, this object is achieved by a framework support, in particular for a framework, a formwork structure or the like, comprising two U-shaped profile supports which are elongated in a framework support longitudinal direction, each with two profile legs and a profile web connecting the two profile legs to one another, wherein the two profile supports are detachably connected to one another by means of a plurality of connecting elements, wherein the profile webs of the profile supports face one another, with interposition of at least one spacer element.
In the framework support constructed according to the invention, the profile supports that provide an essential component of the same are not inseparably connected to one another. The connection of the profile supports is produced by means of connecting elements designed, for example, as screw bolts, with interposition of the spacer elements.
This makes it possible to move the individual components of such a framework support to the location intended for installation and only then to assemble it there to form a larger and therefore significantly heavier framework support. Furthermore, the construction of such a framework support with components that can be detached from one another enables the use of parts that are particularly suitable for the intended purpose in a simple manner.
To connect the profile supports to one another or to other components, it is proposed that in the profile web of each of the profile supports at least one row of first profile support openings following one another in the framework support longitudinal direction for the passage of a connecting element and at least one row of second profile support openings arranged one after the other in the framework support longitudinal direction, orthogonal to the framework support longitudinal direction and arranged at a distance from the at least one row of first profile support openings, are designed for the passage of a connecting element, and that:
A high degree of variability in the structure can be supported by the fact that a second profile support opening forming a pair with each first profile support opening is provided in association with each first profile support opening.
In order to provide a large surface for the interaction of a framework support according to the invention with other components to be coupled to it or to be supported on it, on which such support can take place, it is proposed that for each of the profile supports a first of the profile legs provides a first profile support side surface and a second of the profile legs provides a second profile support side surface, wherein the first profile support side surfaces of the first profile legs together provide a first framework support surface region and the second profile support side surfaces of the second profile legs together provide a second framework support surface region.
In order to avoid mutual interference with components engaging between the two profile supports of a framework support according to the invention, such as vertical standards of a framework carrying perforated discs, on each of the profile supports in the transition from the first profile support side surface to a profile support end face formed on the profile web and facing the respective other profile support, a chamfer or rounding can be formed, and/or a chamfer or rounding can be formed on each profile support in the transition from the second profile support side surface to the profile support end face.
In order to be able to efficiently use the various profile support openings for a high degree of variability in the construction of a framework support or a support structure constructed therewith, a distance between the first profile support openings positioned closer to the first profile leg and the first profile support side surface can be greater than a distance for each of the profile support between the second profile support openings positioned closer to the second profile leg and the second profile support side surface.
At least one, preferably each, spacer element can be elongated in a spacer element longitudinal direction and have at least two spacer element openings following one another in the spacer element longitudinal direction for the passage of a connecting element.
In adaptation to the opening pattern of the various profile support openings provided in the profile supports, a distance between at least two spacer element openings, preferably directly following one another in the longitudinal direction of the spacer element, can correspond to the distance or an integer multiple of the distance between two first profile support openings, preferably directly following one another in the framework support longitudinal direction, and/or to the distance or an integer multiple of the distance between two second profile support openings, preferably directly following one another in the framework support longitudinal direction.
In order to avoid that the spacer element protrudes beyond the profile supports, regardless of the orientation with which a spacer element is integrated between two profile supports, it is proposed that at least one, preferably each spacer element has spacer element end faces that are spaced apart from one another in the spacer element longitudinal direction, and that for at least one, preferably each, spacer element end face, a distance between a spacer element opening, preferably directly adjacent to the spacer element end face, and the spacer element end face in the direction of the spacer element longitudinal direction is less than or equal to the distance between the second profile support openings and the second profile support side surface of each of the profile supports, or/and that at least one, preferably each spacer element has spacer element side surfaces that are spaced apart from one another orthogonally to the longitudinal direction of the spacer element, for example substantially parallel to one another, and that for each of the profile supports, a distance between the spacer openings following one another in the spacer longitudinal direction and the spacer side surface in at least one, preferably each spacer side surface, substantially corresponds to the distance between the second profile support openings and the second profile support side surface.
An easy-to-handle structure of a framework support can also be facilitated in that at least one, preferably each profile support is made with aluminum material, preferably by extrusion, and/or in that at least one, preferably each spacer element is made with aluminum material, preferably by extrusion.
The invention further relates to a framework support system, comprising at least one framework support constructed according to the invention and at least one insertion element elongated in an insertion element longitudinal direction and/or at least one framework support supporting element and/or at least one framework support connecting element elongated in a connecting element longitudinal direction.
In order to be able to couple an insertion element to the profile supports using the profile support openings formed in the profile supports of a framework support, it is proposed that at least one row of insertion element openings following one another in the insertion element longitudinal direction is provided in the at least one insertion element for the passage of a connecting element, wherein the distance between at least two first profile support openings, preferably directly following one another in the framework support longitudinal direction, and/or the distance between at least two second profile support openings, preferably directly following one another in the framework support longitudinal direction, substantially corresponds to the distance or an integer multiple of the distance between at least two insertion element openings, preferably directly following one another in the insertion element longitudinal direction.
A further increased variability in the structure can be achieved in that at least two rows of insertion element openings following one another in the insertion element longitudinal direction are provided in the at least one insertion element, wherein a distance between directly adjacent insertion element openings in each row of insertion element openings is smaller than a distance between directly adjacent insertion element openings of different rows of insertion element openings.
An insertion element can be easily integrated into a framework support in different installation positions if the at least one insertion element has insertion element side surfaces that are spaced apart from one another orthogonally to the insertion element longitudinal direction, for example substantially parallel to one another, and if at least one, preferably each row of insertion element openings following each other in the longitudinal direction of the insertion element are substantially at the same distance from each insertion element side surface.
In order to be able to couple further components to such an insertion element in a support structure, it can be provided that at least one insertion element has a substantially rectangular cross-sectional profile with narrow sides that are opposite one another, for example substantially parallel to one another, and broad sides that are opposite one another, for example substantially parallel to one another, and that an undercut profile that is open to the outside is provided on at least one narrow side. Furthermore, an easy-to-handle structure can be facilitated by producing at least one insertion element with aluminum material, preferably by extrusion.
To provide a support interaction between a framework support and a framework support supporting element, at least one framework support supporting element can comprise a support head with a framework support supporting surface and a connecting web protruding from the framework support supporting surface and to be positioned between the two profile supports of a framework support with at least one connecting web opening for the passage of a connecting element. Furthermore, to adapt the positioning of a framework support, at least one framework support supporting element can comprise a spindle arrangement.
In order to be able to stably couple a framework support supporting element to the framework support using the profile support openings formed in the profile supports of a framework support, a distance between the at least one connecting web opening and the framework support supporting surface can substantially correspond to the distance between the first profile support openings and the first profile support side surface in each of the profile supports or to the distance of the second profile support openings to the second profile support side surface for each profile support.
In order to be able to easily couple one or different framework supports with support structure elements arranged at different distances from one another, it is proposed that at least one first connecting web opening and at least one second connecting web opening are provided in the connecting web, wherein a distance between the at least one first connecting web opening to a framework support supporting element longitudinal axis is smaller than a distance of the at least one second connecting web opening to the framework support supporting element longitudinal axis.
The construction of a support structure can be facilitated if two first connecting web openings are provided in the connecting web opposite one another with respect to the framework support supporting element longitudinal axis, and/or if two second connecting web openings are provided in the connecting web opposite one another with respect to the framework support supporting element longitudinal axis. The support head of a framework support supporting element constructed in this way can thus be used in two positions rotated by 180° relative to one another, each using the same type of connecting web openings.
For each profile support, a distance between the first profile support side surface and the second profile support side surface can be substantially the sum of a width of at least one spacer element between two spacer element side surfaces lying orthogonally to a spacer longitudinal direction at a distance from one another, for example substantially parallel to one another, spacer element side surfaces and correspond to a width of at least one insertion element between two insertion element side surfaces lying at a distance from one another orthogonally to an insertion element longitudinal direction, for example substantially parallel to one another. In this way, it can be avoided that during the assembly, regions protruding beyond the profile support side surfaces, for example of a spacer element and an insertion element, are not present.
The invention further relates to a support structure, such as a framework or a formwork structure, comprising at least one framework support constructed according to the invention and/or at least one framework support system according to the invention.
To avoid a structure that bends strongly even under higher loads, it is proposed that at least one insertion element and/or at least one framework support connecting element in at least one of its longitudinal end regions, preferably in its two longitudinal end regions, is connected to a framework support by means of at least two connecting elements positioned at a distance from one another in the framework support longitudinal direction. If the possibility is to be created of being able to arrange an insertion element in different angular positions with respect to a framework support, it is advantageous if at least one insertion element is connected to a framework support in at least one of its longitudinal end regions, preferably in its two longitudinal end regions, by means of a single connecting element, so that this insertion element can be pivoted about the connecting element with respect to the framework support.
A high variability in the structure that is easy to implement can be achieved in that two support structure elements, each to be coupled to a framework support or different framework supports by means of a framework support supporting element associated with them, have a support structure element distance from a plurality of predetermined support structure element distances from one another, and that support structure element distances of the plurality of support structure element distances, the distance of the at least one first connecting web opening to the framework support supporting element longitudinal axis, the distance of the at least one second connecting web opening to the framework support supporting element longitudinal axis and the distance of the profile support openings provided for coupling to the framework support supporting elements associated with the two support structure elements, directly following one another in the framework support longitudinal direction, of first profile support openings and second profile support openings of the framework support or the different framework supports meet the following conditions:
wherein:
If the conditions A, B, C are met, it is possible to realize more than two different support structure element distances on one or different support structures using only two different types of connecting web openings, which differ in their respective distance from the framework support supporting element longitudinal axis.
The present invention is described in detail below with reference to the attached figures. In particular:
Before the structure of a framework support, a framework support system and of a support structure constructed with one or more such framework supports or framework support systems is described in detail below with reference to
In the region of each profile web 26, 28, each profile support 14, 16 has a profile support end face 42, 44. In the assembled state of a framework support 10, the two profile supports 14, 16 are positioned so that their profile support end faces 42, 44 face each other and form an overall structure that is substantially mirror-symmetrical with respect to the plane of symmetry E.
A row R1 of first profile support openings 46 is provided in each of the two profile supports 14, 16, as illustrated in
Likewise, each profile support 14, 16 has a row R2 of second profile support openings 48. The second profile support openings 48 of row R2 are also arranged one after the other in the profile support longitudinal direction LG and have a mutual distance D2, which substantially corresponds to the distance D1 of the first profile support openings 46 to one another in the profile support longitudinal direction LG. Furthermore, the two rows R1, R2 are arranged in each of the profile supports 14, 16 in such a way that they have a distance D3 to one another orthogonally to the longitudinal direction of the profile support LG, which substantially corresponds to the distance D1 and D2, respectively. The two rows R1, R2 are further arranged in each of the profile supports 14, 16 in such a way that a second profile support opening 48 lies orthogonal to the profile support longitudinal direction LG next to each first profile support opening 46, so that respective pairs P of adjacent first and second profile support openings 46, 48 of the two rows R1, R2 are formed.
The row R1 of first profile support openings 46 is arranged in the respective profile web 26, 28 so that it has a distance D4 substantially orthogonal to the profile support longitudinal direction LG to the first profile support side surface 30, 32 of the first profile leg 18, 22 positioned closer to this row R1, which is greater than a substantially orthogonal distance D5 of the row R2 of second profile support openings 48 to the second profile support side surface 34, 36 of the second profile leg 20, 24 which is closer to the respective row R2.
The spacer element 50 is elongated in a spacer element longitudinal direction LD and has two spacer element openings 52 which follow one another in the spacer element longitudinal direction LD. A distance D6 of the two spacer element openings 52 in the spacer element longitudinal direction LD to one another corresponds to the distance D1 of the first profile support openings 46 to one another, the distance D2 of the second profile support openings 48 to one another and the distance D3 between a respective first profile support opening 46 and a respective one second profile support opening 48 of a respective pair P. This makes it possible to insert such a spacer element 50 either between the two profile supports 14, 16 in such a way that each of the two spacer element openings 52 is aligned with one of two directly adjacent first profile support openings 46, or that each of the two spacer element openings 52 are each aligned with one of two directly adjacent second profile support openings 48, or that one of the spacer element openings 52 is aligned with one of the two profile support openings 46, 48 of a pair P and the other spacer element opening 52 with the other of the profile support openings 46, 48 of this Pair P. This alignment is of course given for each of the two profile supports 16, 18.
To produce a solid connection, connecting elements 54 can be passed through the first profile support openings 46 or second profile support openings 48 of the two profile supports 14, 16 which are aligned with the two spacer element openings 52 of a respective spacer element 50. These connecting elements 54 can be designed, for example, as a screw bolt with a head 56 and a threaded shaft 58 onto which a nut 60 can be screwed.
To obtain an easy-to-handle structure, the two profile supports 14, 16 are preferably constructed with aluminum material and manufactured, for example, by extrusion. Likewise, each spacer element 50 can also be constructed with aluminum material and produced by cutting off an extruded profile with a thickness required to adjust the mutual distance A to be specified for the two profile supports 14, 16. Such an extruded profile can substantially be designed as a hollow profile, so that an inner opening 62 which runs substantially completely through it is formed in each spacer element 50 to minimize weight.
The two profile supports 14, 16 can, for example, be brought separately from one another to the intended installation location and can be assembled there with the required number of spacer elements 50 and connecting elements 54 to form a framework support 10.
When assembling the profile supports 14, 16 with the spacer elements 50 to be arranged between them, different positionings of the spacer elements 50 can be provided, as mentioned above and illustrated in
A distance D9 of a respective spacer element opening 52 in the spacer element longitudinal direction LD to a directly adjacent spacer element end face 74, 76 is smaller than the respective distance D7 or D8. This leads to the fact that, when installed in such a way, in which a spacer element 50 interacts with the two profile support openings 46, 48 of a respective pair P in each of the profile supports 14, 16, the spacer element 50 with its spacer element end face 74 or 76, which is curved in the example shown, which is positioned closer to the second framework support surface region 40, is set back inwards with respect to this.
The insertion element openings 78 have the same distance D12 or D13 from respective insertion element side surfaces 80, 82 which are arranged at a distance from one another orthogonally to the insertion element longitudinal direction LE and are substantially parallel to one another, so that the insertion element openings 78 are positioned, orthogonal to the insertion element longitudinal direction LE, centrally in the insertion element 68. It should also be noted that each insertion element opening 78 in the insertion element 68, which is designed as a hollow profile part, comprises an opening portion in each of the two opposing wall regions, so that a respective connecting element 54 can be completely passed through the insertion element 68.
The distance D12 or D13 of the insertion element openings 78 to the two insertion element side surfaces 80, 82 corresponds to the distance D4 of the first profile support openings 46 to the respective first profile support side surface 30, 32. In the framework support system 64 illustrated in
In a framework support system 64 constructed in this way, the insertion element 68 lies with each of its two longitudinal end regions directly adjacent to or above a spacer element 50. To make this possible, the spacer element 50 and the insertion element 68 are dimensioned such that a distance D14 between a respective one first profile support side surface 30, 32 and second profile support side surface 34, 36 in each of the profile supports 14, 16 substantially corresponds to the sum of a width BD of the spacer element 50 measured between the two spacer element side surfaces 70, 72 and a width BE of the Insertion element 68 measured between the insertion element side surfaces 80, 82. At the same time, this also leads to a structure in which the insertion element 68 can rest in its longitudinal end regions on the spacer elements 50 of the two framework supports 10 or can also be additionally supported by them and in particular can also be blocked against a pivoting or walking movement.
In the insertion element 68, the insertion element openings 78 are arranged such that their distance D10 in the insertion element longitudinal direction LE is smaller than the distance between first profile support openings 46 directly following one another in the framework support longitudinal direction LG. In particular, the distance D10 between directly adjacent insertion element openings 78 can be half the distance D1 of directly adjacent first profile support openings 46. This enables a comparatively fine adjustment of the installation position of the insertion element 68 in a respective framework support 10 in the framework support longitudinal direction LG. In particular, it can be provided that the distance D1 corresponds to an integer multiple of the distance D10, for example three or four times, in order to be able to achieve an even finer rasterization.
A row R5 of first connecting element openings 96 and, orthogonal to the connecting element longitudinal direction LV at a distance therefrom, a second row R6 of second connecting element openings 98 are provided in the framework support connecting element 94. These first connecting element openings 96 and second connecting element openings 98 are arranged in the framework support connecting element 94 in such a way that an opening pattern corresponding to the opening pattern of the first and second profile support openings 46, 48 is provided. The framework support connecting element 94 can thus be positioned in the adjacent region of two framework supports 10 to one another in such a way that the first and second connecting element openings 96, 98 provided therein are aligned with the respective first and second profile support openings 46, 48 in the two profile supports 14, 16 of the profile supports 10 to be connected to one another and the framework support connecting element 94 can be firmly connected to each framework support 10 by a plurality of connecting elements 54. The thickness of the framework support connecting element 94 substantially corresponds to the thickness of the spacer elements 50 arranged between the profile supports 14, 16 of the framework supports 10 to be connected to one another and thus to the distance A to be provided between the two profile support end faces 42, 44.
This distance A is dimensioned such that when building a support structure, it is possible to pass support structure elements of the same between the two profile supports 14, 16 of a framework support 10. This is illustrated in
In addition, one or more support elements 112 may be used to construct a support structure 64 or 66′. Such a framework support supporting element 112 is illustrated in
The framework support supporting element 112 has a support head 114, which provides a framework support surface 116. A connecting web 118 is provided approximately in the middle of the framework support surface 116, in which a plurality of connecting web openings 120 are each provided at the same distance D15 from the framework support surface 116. The distance D15 corresponds to the distance D5 of the second profile support openings 48 to the respective second profile support side surface 34, 36 for each of the profile supports 14, 16.
In the framework support system 64 shown in
The mutual distance between the connecting web openings 120 can vary or can be selected in such a way that when using such a framework support supporting element 112 with variously dimensioned support structure elements of a framework, for example vertical supports combined in frame-like structures, it is possible to align several of framework support supporting elements 112 positioned in this way at a fixed predetermined distance from one another with one or more framework supports 10 or the second profile support openings 48 provided therein.
The framework support supporting element 112 shown in
With such a framework support 10 or framework support system 64, as illustrated for example in
If an insertion element 68 is coupled with a framework support 10 only by means of a single connecting element 54, as illustrated in
Another particularly advantageous design aspect of a framework support system 64 according to the invention or a support structure constructed therewith is explained below with reference to
All configurations of framework systems 64 shown in
If these conditions are met, it is possible to build various framework support systems 64 with a type of framework support supporting elements 112, as shown for example in
In the frame support system 64 of
In order to compensate for this oversize, the distance D16 of the first connecting web openings 120 to the framework support supporting element longitudinal axis LS, which corresponds to the respective support structure element longitudinal axis LT in the framework support system 64 shown in
In the example shown in
The distance D17 of the second connecting web openings 121 to the framework support supporting element longitudinal axis LS is set to 56 mm, so that in the two second connecting web openings 121 of the two framework support supporting elements 112 facing away from each other, their mutual distance is 1200 mm and thus these two second connecting web openings 121 can be aligned with the two second framework support openings 48, which are arranged at a distance of 1200 mm from one another, and can be coupled by respective connecting elements 54.
In this case, in condition B, the number n2 is 12, the support structure element distance DT2 is 1088 mm, the distance D17 of the second connecting web openings 121 to be used to the framework support supporting element longitudinal axis LS of the respective framework support supporting element 112 is 56 mm, and the distance between two directly adjacent second profile support openings 48 is again 100 mm.
In the exemplary embodiment of a framework support system 64 shown in
The preceding explanation shows that by selecting the different sizes that meet the conditions A to C, it is possible to realize more than two different support structure element distances that do not correspond to an integer multiple of the distance D2 with just two differently positioned types of connecting web openings 120, 121.
The number of support structure element distances that can be achieved naturally increases in each of the exemplary embodiments of framework support systems 64 shown in
It should also be noted that the conditions A to C can be met with a variety of other support structure element distances DTi using the same framework support supporting elements 112, for example if these support structure element distances DTi are increased by multiplying by an integer, for example 2.
