The present invention relates to a base that is couplable to a building wall to connect said wall to a reinforced concrete foundation. The invention also relates to a building wall comprising said base and a building construction method comprising said wall. The present invention is particularly, albeit not exclusively, suitable for application to the construction of buildings having a light structure, for example comprising wooden or steel or aluminium walls.
In the sector relating to the construction of temporary or permanent buildings having a light structure, reinforced concrete foundations are produced in the prior art to which the elevated parts of buildings are normally constrained by means of the use of angle or flat brackets and of the so-called “hold-downs”.
There is a known difficulty, in particular in the case of elevated pre-fabricated structures, in producing concrete foundations with the required planimetric and altimetric laying precision. The greater the extension of the panels or walls constituting the elevated structure the greater said difficulty. The hold-downs and the brackets normally used in wooden constructions, respectively constrain the vertical and horizontal movements of the elevated structure with respect to the foundation, but do not allow any adjustment of the height and of the inclination with respect to the vertical direction of the wall, during the installation steps. Consequently, the required installation precision is only achievable with lengthy timeframes and high costs. The fact that the light elevated structure rests directly on the foundation also determines a plurality of energy-related drawbacks, such as heat losses and rising damp. This latter problem is particularly felt in the case of wooden buildings as the rising damp determines a quicker degradation of the elevated structure. To partially overcome this problem, a base wooden beam of wood base is produced in the prior art, with harder and more durable or suitably treated wood, interposed between the foundation and the building walls. Even this latter solution is not however optimal as a wooden base structure, the beam, is in any case placed in direct contact with the cement structure. A further drawback of the solution with wooden beam is determined in that the latter is subject to crushing by orthogonal compression to the fibres by effect of the weight of the elevated structure bearing thereon.
The main object of the present invention is thus that of providing a base for building walls that allows the above-reported drawbacks to be overcome with reference to the aforementioned prior art while achieving the following advantages:
A further object is that of providing a wall or pre-fabricated panel for the construction of buildings provided with a base constrainable to a reinforced concrete foundation capable of achieving the above-indicated advantages.
A further object is that of indicating a construction method for the construction of buildings comprising a plurality of walls or panels of the aforementioned type.
Said advantages can be achieved by means of a building wall base comprising:
Further advantages are achieved by means of an optional tubular member filled with a mixture consisting of cement grout or another material that is suitable and susceptible to being interposed, in position, between said base socle and said foundation slab.
Other advantages are achieved by means a building wall base of the above-indicated type and further comprising a thermally insulating layer susceptible to being interposed, in position, between said panel and said base socle.
According to a further aspect of the invention, the aforementioned problems are resolved by means of a building wall comprising a panel made of a light material and a base that include:
second constraint means to rigidly constrain, in position, said panel to said base socle.
According to a third aspect of the invention, the same problems as indicated above are resolved by means of a building construction method comprising the steps of:
Further characteristics and advantages of the invention will become clearer in the light of the detailed description of preferred but non-exclusive embodiments of a building wall base according to the present invention illustrated by way of a non-limiting example, with the assistance of the accompanying drawings, wherein:
With reference to the accompanying drawings, three distinct embodiments of a building wall according to the present invention are respectively indicated by 10a, 10b, 10c.
Each of the building walls 10a, 10b, 10c includes a panel 2 and, respectively, a base 1a, 1b, 1c connecting the panel 2 and a foundation slab (not shown as not the object of this invention).
The panel 2 consists of a light prefabricated panel made of wood or steel or aluminium or other material.
According to other embodiments (not shown), the panel 2 is of another type, possibly consisting, for example, of a plurality of bricks or other types of members rigidly constrained to each other.
The foundation slab is made of reinforced concrete or other suitable material.
The building walls 10a, 10b, 10c differ from each other in the structure of the respective bases 1a, 1b, 1c. In the three embodiments 1a, 1b, 1c of the base, some of the components are structurally and functionally identical and shall therefore be indicated by the same numeric references in the following description and in the accompanying drawings.
With initial reference to
The base socle 3a has a plan width that is equal to or slightly greater than the plan dimensions of the panel 2 and consists of an aluminium extrusion.
According to other embodiments the base socle 3a is made of other metal or polymer material and with techniques other than extrusion, for example by moulding or casting.
The base 1a further comprises first constraint means to rigidly constrain, in position, the base socle 3a to the foundation slab. Said first constraint means are made in such a way as to allow adjustment of the position and orientation of the orientation of the base socle 3a with respect to the foundation slab. In particular, the first constraint means allow adjustment of the distance between the base socle 3a and the foundation slab as well as the desired planimetric and altimetry alignment of the base socle 3a with respect to the foundation slab. To allow said adjustment of the distance the base socle 1a further comprises a plurality of angle brackets 7a, each of which consists of a first flat plate 17a, susceptible to being arranged, in position, almost parallel to the foundation slab, and a second flat plate orthogonally arranged with respect to the first flat plate 17a. The base socle 3a has horizontal grooves 8C that can engage teeth 8A to hold the angle brackets 7a to the base sock 3a.
The angle brackets 7a are divided into pairs of brackets 7a that are opposed with respect to the wall 10a. The pairs of brackets 7a are regularly distributed along the wall 10a so as to ensure that the wall 10a is supported in a uniform manner.
The first constraint means comprise the first flat plate 17a of the angle bracket 7a and for each flat plate 17a a pair of threaded couplings usable to adjust, in position, the distance between the base socle 3a and the foundation slab Each threaded coupling of the first constraint means comprises a threaded rod 11, susceptible to being constrained, in position, to a first end 11a of the foundation slab, and an adjustment bushing 8 susceptible to being constrained, in position, to a second end 11b of the threaded rod 11.
During the installation steps, the constraint of the first end 11a to the slab is obtained by executing a blind hole in the foundation slab, inserting into said hole the first end 11a together with a binder, for example a resin, and waiting for the maturation of the binder.
In position, the threaded rods 11 pass through respective holes 15 provided on the first flat plate 17a and the adjustment bushings 8 are screwed onto the second ends 11b of the threaded rods 11 in such a way that the respective first flat plate 17a is interposed between the foundation slab and the adjustment bushings 8. It is possible to adjust the height and the inclination of each rod 7a with respect to the foundation slab by tightening more or less the adjustment bushings 8 on the threaded road 11. The holes 15 are preferably slotted so as to advantageously allow adjustment of the planimetric position and thus of the alignment of the walls.
The first constraint means further comprise, for each threaded rod 11, a respective quick-connect fastening cotter pin 9 of suitable thickness interposed between the respective first flat plate 17a and the foundation slab and in contact with these. The quick connection is guaranteed in that each fastening cotter pin 9 comprises a hole 16, susceptible to being crossed by a respective threaded bar 11, that is laterally opened by means of a notch 19, which allows insertion or removal of the fastening cotter pin 9 even when the respective bracket 7a, threaded rod 11 and adjustment bushing 8 have already been implemented.
The base 1a further comprises a first tubular member 5 that is filled with a mixture 6 consisting for example of a cement grout, or other suitable material such as high density polyurethane foam or another material still. The tubular member 5 susceptible to being interposed, in position, between the base socle 3a and the foundation slab to fill the air space remaining between the base socle 3a and foundation after fastening of the base 1a, by means of the first constraint means, has taken place. On maturation of the mixture 6, the tubular member 5 offsets foundation slab irregularities and efficiently transmits the loads of the wall 1a. Furthermore, the tubular member 5 also carries out the separating and thermal cutting function between the foundation and the base socle 3a.
The presence of the tubular member 5 filled with cement grout is optional, being absent in some embodiments of the present invention. According to these latter variant embodiments (not shown as they are not the object of the invention), the tubular member 5 is replaced by other functionally similar members obtained by traditional techniques, for example by pouring the cement grout into the lateral containment formwork beneath the base socle 3a or by cement mortar reinforcement beneath the base socle 3a.
The base 1a further comprises an insulating layer 4 having a thermal cutting function, susceptible to being interposed, in position, between the panel 2 and the base socle 3a, so as to thermally insulate the wall 2 from the base socle 3a.
The presence of the thermally insulating layer 4 is optional, being absent in some embodiments of the present invention.
The wall 2 rests on the thermally insulating layer 4 or directly on the base socle 3a. To rigidly constrain, in position, the panel 2 to the base socle 3a, the base 1a comprises second constraint means, consisting of the second plate 18a of the angle bracket 7a, of a plurality of screws 12 to be constrained to each other, in position, the second plate 18a and the base socle 3a and of a plurality of nails 13 to constrain between them the second flat plate 18a and the panel 2, when the panel 2 is made of wood. Where the panel 2 is made of another material the plurality of nails 13 may be conveniently replaced by a plurality of screws.
With reference to the variant of
With reference to the variant of
According to the present invention, the construction of a building comprising at least one building wall 10a, 10b, 10c, in a variant embodiment wherein both the grout-filled tubular member 5 and the thermally insulating layer 4 are present is achieved by means of a method that includes the following steps:
Where the tubular member 5 and/or the insulating layer 4 should not be present, the respective method steps are omitted
The presence of the base socle 3a, 3b, 3c allows the following:
The present invention thus allows the aims proposed in reference to the aforementioned prior art to be achieved, while at the same time achieving further advantages, such as improving the durability of the construction and reducing the thermal bridge at the base of the building.
