Abstract

The structure comprises members (1) consisting of pillars (2) and cross beams (3), provided, at the upper faces thereof, with continuous recesses, (4, 4') which latter form steps effective to support the end portions of adjacent horizontal members (3'), i.e. floors and cross beams. The recesses contain reinforcement (7) to strengthen the junctions. <IMAGE>

Description

SPECIFICATION Bearing structure for buildings The present invention relates to a bearing structure for building constructions.

As it is well known in the building field the need is often felt of locating horizontally extending members, such as cross beams and floors on load bearing vertical structures.

This operation usually requires, during the assembling stage, to use temporary propping structures, effective to suitably support the mentioned horizontally extending members. This fact, obviously, represents a great drawback both from the point of view of the involved labour costs and from that of the long time required for erecting the building.

Accordingly, the task of the present invention is that of eliminating the thereinabove cited drawback, by providing a load bearing structure, for buildings in general, effective to support the horizontally extending members (cross beams, floors and the like) during the temporary assembling stage, without using any propping temporary structures.

Within the scope of this task, it is a main object of the present invention to provide a load bearing structure, for buildings in general, which may be prefabricated or which can be made during the erection of the building.

According to one aspect of the present invention the above task and object as well yet other objects which will become more apparent hereinafter are achieved by a load bearing structure for buildings in general, said structure comprising coupled pillars and/or cross beams provided with upper steps, both of the re-entering and projecting type, effective to bear the adjacent horizontal members, that is the cross beams, on a side, and floors on the other, during the temporary assembling step, the steel reinforcement rods for coupling the assembly projecting at said steps.

In particular, according to an advantageous embodiment, the load bearing structure comprises as the constituting elements thereof: a first member, consisting of two pillars rigid with a cross beam; a second member, consisting of a single cross member; a third member, consisting of a pillar rigid with a cross beam or member.

Further characteristics and advantages of the bearing structure for buildings in general according to the present invention will become more apparent from the following detailed description of a preferred embodiment thereof, being illustrated by way of an exemplary and not limitative example in the figures of the accompanying drawing, where:: fig. 1 is a perspective view illustrating the aforesaid first member of the load bearing structure, consisting of a cross beam, coupled to two end pillars; fig. 2 illustrates partially that same constructional member, provided with projecting brackets; fig. 3 illustrates a perspective view of the second constructional member, consisting of a single cross beam; fig. 4 is a partial view illustrating that same single cross beam, provided with a step, reentering at the small sides thereof; fig. 5 is a perspective view illustrating the procedure for coupling a first member with a second member; fig. 6 is another perspective view illustrating the third member of the subject load bearing structure, consisting of a single pillar, rigid with a cross beam;; fig. 7 illustrates the end portion of the cross beam of that same third member, provided with a perimetrical tapering, for a recessed type of supporting action; figs. 8, 9 and 10 illustrate a cross section of the aforesaid members, representing the several possible cases of coplanarity between the floors and cross members or beams, that is, respectively, both at the extrados and at the intrados; at the extrados only; at neither of the two; fig. 11 is a partial longitudinal cross section view, at a bearing or supporting member, therein the coupling frame is illustrated; fig. 12 illustrates the coupling of the aforesaid first, second and third members, in order to form a scaffolding; fig. 1 3 illustrates the superimposition or stacking of the first members, in order to provide an elevation structure; and fig. 14 illustrates the arrangement of the reinforcement rods, projecting from the supporting or bearing portion of a third member and effective to couple the floors.

With reference to the numbers of the figures of the accompanying drawings, the load bearing structure for buildings in general according to the present invention comprises a first member 1 consisting of two pillars or uprights 2, rigid with a cross beam or member 3.

Said first member is provided, at the top thereof, at one or more sides of the cross beam, with suitable steps, indicated at 4 and 4'.

More specifically, said steps may be so sized as to cause the floor to be coplanar, at the extrados and, possibly at the intrados, with one another and with said cross beam (figs. 8 and 9), or as to cause said floors to be at a higher level than the cross beam, in order to form on the latter a suitable channel (fig. 10).

Moreover said cross beam 3 may be provided with a bracket projecting portion 5, at the small sides thereof.

The second member of the subject load bearing structure consists of a single cross beam 3', also provided at the top thereof and at one or more of its sides with suitable steps, indicated at 4 and 4' for supporting the floors.

That same second member may also be provided with an offset 4", for resting in a recessed way on the adjacent upright or pillar or on a bracket 5 thereof.

The third member 6 consists of a pillar 2 rigid with a cross beam 3 and it is provided, at the top, with suitable steps 4 and 4',formed at one or more sides of said cross beam.

The latter, moreover may possibly be provided with an offset 4" for resting in a recessed way on the adjacent upright or pillar or on a bracket thereof.

In particular the steps 4', formed at the top of the pillars preferably extend for not less than 1/3 and not more than 2/3 of the thickness of the pillars.

It is furthermore provided that the steel reinforcement rods 7 project from the pillar, or cross beams, at the steps in such a way that, by pouring concrete into the gaps defined by said steps, it is possible to obtain a perfect junction, effective to bind the assembly.

It should be noted that the starting materials for making the load bearing structure according to the present invention are the known ones as generally used in the reinforced concrete treating processes.

Owing to the great simplicity of the component elements thereof, the load bearing structure according to the present invention may be either prefabricated or erected in situ.

In addition the complementary structures, such as blocks, landings, closure walls and the like may be erected in conventional ways, or they can be industrially produced and inserted into the main structure.

From the above disclosure and the figures of the accompanying drawings are self-evident the great functionality and use facility characterizing the load bearing structure for buildings in general according to the present invention.

Claims

1. A load bearing structure for buildings in general, comprising coupled pillars and/or cross beams provided with upper steps, both of the re entering and projecting type, effective to bear the adjacent horizontal members, that is cross beams on a side and floors on the other, during the temporary assembling step, the steel reinforcement rods for coupling the assembly projecting at said steps.
