[0035] It is specified that in the present description, the phraseology and terminology used, as well as the figures of the attached drawings, even as described, have the sole function of better illustrating and explaining the present invention having a non-limiting example function of the same invention.

[0036] For ease of understanding, like reference numerals have been used, where possible, to identify like common elements in the figures. It is understood that elements and features of one embodiment may be suitably combined or incorporated into other embodiments without further specification.

[0037] DESCRIPTION OF CERTAIN EMBODIMENTS OF THE PRESENT INVENTION

[0038] Referring to Figures 1 and 2, a typical building structure 100, of the steel-concrete type, is shown schematically during the assembly phases.

[0039] The building structure 100 is formed from a plurality of vertical pillars 110, only one of which is visible in [Fig.l], to which horizontal beams 111 are connected arranged to support a floor 113.

[0040] In its most traditional configuration, each beam 111 has a bottom or base 114 and a lattice body 112 secured to the bottom 114.

[0041] The lattice body 112 is formed of bars or longitudinal currents 112a arranged parallel to the development of the beam 111 and of connecting rounds 112b fixed below the bottom 114 and above the longitudinal currents 112a.

[0042] The floor 113 may be formed from a single panel or from several panels which may be of the honeycomb or plate type. By the term floor is meant a flat two-dimensional structure of orthogonal structural load which contributes to static safety, by distributing the loads on the beams 111.

[0043] In Figures 1, 2 and 3, said device 10 for stabilizing the building structure 100 is shown during the assembly phases.

[0044] The applicant has learned from experience that for optimal load balancing, it is preferable to apply to each beam 111 at least two separate devices 10, arranged approximately the width of the floor 113.

[0045] Although the present description refers to the building structure 100 described above, an expert in the field will understand that the device 10 can be used to temporarily stabilize the loads even of building structures having different conformations.

[0046] The device 10 comprises a tubular anchoring member 11 having an oblong conformation and configured to be stably fixed to the lattice body 112 along a transverse direction T orthogonal to the floor 113.

[0047] According to one embodiment, the anchoring member 11 may be a pipe 11a made of metallic material. The pipe 11a is advantageously open at both ends. The section of the pipe 11a may be round or polygonal.

[0048] By way of example only, the pipe 11a may have a round section with a diameter of between about 10 mm and about 40 mm, for example around 25 mm, a thickness of between about 1 mm and about 3 mm, for example around 2 mm, and a length of between about 50 mm and about 250 mm, for example around 150 mm.

[0049] In particular, the anchoring member 11 is fixed to the longitudinal currents 112a and the transverse direction T is orthogonal both to the development of the longitudinal currents 112a and to a head surface 113a of the floor 113. By head surface 113a is meant the surface directly facing the beam 111. The surface of the head 113a is a substantially vertical surface.

[0050] The anchoring member 12 may be attached to the lattice body 112 by means of weld points. An expert in the sector will understand that other mechanical attachment methods known in the building and machining sector may alternatively be chosen.

[0051] The device 10 comprises at least one load application member 12 comprising a positioning element 13, slidably associated with the anchoring member 11 by means of a guide 14 along the transverse direction T.

[0052] The positioning element 13 is inserted inside the anchoring member 12 which can slide, in a guided manner, relative to the latter in a manner which can be defined as "telescopic". The anchoring member 12, in addition to ensuring fixing to the beam 111, makes it possible to protect the positioning element 13.

[0053] The load application member 12 also comprises a planar stop element 15 configured to abut against the floor 113. The stop element 15 is associated with a head end of the positioning element 13.

[0054] The load applying member 12 can be positioned along the transverse direction T between a first position, or remote position, in which the positioning element 13 is mainly disposed inside the anchoring member 12, and a second position, or loading position, in which the element of stop 15 is in abutment against the floor 113, exerting a thrust on it to balance any eccentric loads which temporarily insist on the beam 111.

[0055] With reference to [Fig.l], the device 10 comprises a single load application member 12. In this case, the eccentric load acting on the beam 111 can only be balanced in one direction. Such a configuration is advantageous in the case where the beam 111 is arranged on the perimeter and there are no other structures or elements, beyond the floor 113, which can serve as a stop to balance the stresses.

[0056] In the case of building structures 100 having a different configuration, such as that shown schematically in [Fig.5], the device 10 may comprise two separate load application members 12 configured to be moved along the same transverse direction T, but in opposite directions.

[0057] With reference to the embodiments of Figures 3 to 4, the positioning element 13 is a threaded bar 13a and the guide 14 is formed of at least one threaded guide nut 14a associated, for example, with one end of the anchoring member 12. The length of the threaded bar 13a essentially defines the travel between the first position and the second position as defined above.

[0058] According to the possible embodiments, if the stroke of the threaded bar 13a is not long enough to allow the stop element 15 to come into contact with the floor 113, it is possible to weld one or more extension profiles to the pipe 11a to bring the device 10 closer to the floor 113 while maintaining sufficient contact / thrust rigidity.

[0059] The guide nut 14a can be welded to one of the two ends of the pipe 11a, advantageously to the one which is closest to the stop element 15.

[0060] According to a variant, the guide nut 14a may be associated by interference inside the end of the pipe 11a, [Fig.4], or in another position along the length of the pipe 11a. The interference coupling may be achieved by plastic deformation of the pipe 11a around the guide nut 14a. The interference coupling advantageously makes it possible to obtain a substantially monolithic component and to increase the overall rigidity of the device 10.

[0061] According to a possible embodiment, the pipe 11a can be internally threaded and itself serve as a guide for the threaded bar 13a.

[0062] The stop element 15 may be a plate or a plate 15a having a flat contact surface. The plate 15a is made of metal, preferably steel or one of its alloys.

[0063] The contact surface may be circular or polygonal in shape, for example square or rectangular.

[0064] The contact surface may be between approximately 3000 mm2 and approximately 11000 mm2, preferably between 5000 mm2 and 9000 mm2, for example around 7000 mm2.

[0065] The plate 15a may have a thickness of between approximately 2 mm and approximately 8 mm, for example around 5 mm.

[0066] The positioning of the plate 15a can be obtained by rotating the threaded bar 13a, for example by manually adhering it to the plate 15a, until the plate 15a is pushed onto the head surface 113a of the floor 113, balancing the eccentric load which would rotate the beam 111.

[0067] The applicant has learned from experience that the device 10 should advantageously be arranged at a height such that it aligns the upper edge of the tray 15a with an upper surface of the floor 113, to ensure optimal counterbalancing against tilting.

[0068] According to embodiments, the device 10 may be provided with an adjustment nut 16 fixed in a stable manner along the threaded bar 13a advantageously at the level of the plate 15a, [Fig. 3]. The adjustment nut 16 may be forced with a wrench to improve the coupling between the plate 15a and the floor 113.

[0069] According to later embodiments, illustrated in [Fig.4], the plate 15a can be provided with an internally threaded attachment portion 18, onto which the head of the threaded bar 13a is screwed.

[0070] The head of the threaded bar 13a may optionally be secured to the attachment portion 18 also by means of one or more welding points.

[0071] In this embodiment, the adjusting nut 16 is absent and its function is partially fulfilled by the hooking portion 18. The hooking portion 18 can be provided in place of the adjusting nut 16 also in the embodiment of [Fig.3].

[0072] The hooking portion 18 advantageously projects relative to the main thickness of the plate 15a. In this way, in addition to allowing the threaded bar 13a to be screwed, it can serve as a gripping and adjustment member to promote the coupling between the plate 15a and the floor 113.

[0073] According to the possible embodiments, the attachment portion 18 can be obtained for example by punching the plate 15a. The attachment portion 18 is therefore advantageously part of the plate 15a.

[0074] As an alternative or in combination with what has just been described, the hooking portion 18 can be defined, in part or in whole, in the thickness of the plate 15a.

[0075] According to a variant of the present invention, the load application member 12 may be a piston or a pressure pusher 17 of the hydraulic or pneumatic type, [Fig.6], provided with an actuating member 17a.

[0076] It is clear that modifications and / or additions of parts can be made to the device for stabilizing a building structure 10 described above, without departing from the scope of the present invention.

[0077] It is also clear that, although this invention has been described with reference to a few specific examples, an expert in the field will be able to make other equivalent forms of a device for stabilizing a building structure, having the characteristics all falling within the scope of protection defined by them.

[0078] In the following claims, the references in parentheses are for the sole purpose of facilitating reading and should not be considered as limiting factors of the scope of protection defined by the same claims.
