FR2471461A1 - Metal post for modular building construction - is made up of spaced lengths of angle iron bolted back to back to form e.g. cruciform section - Google Patents

Abstract

Construction post is made up of lengths of angle iron (1) which are bolted together back to back using small iron connecting plates (2), junction elements (9) and/or end-pieces (8). The cross-section of the post presents a configuration of parallel pairs of arms which is identical to that of the end-piece (8) used, e.g. 90 degrees between adjacent plates (2) and/or the end-piece (8). The ends (5) of the horizontal (3) or the inclined beams (4) are lodged into the space between the arms and are bolted in position pref. using shims (6).

Description

 The present invention relates to building elements, bearing columns and independent seats, allowing the realization of buildings evolutive according to the principle of the building game.

 In the known devices of this kind, the vertical load-bearing elements are connected to the horizontal elements by more or less complex assembly nodes requiring special profiles adapted to these types of assembly.

 On the other hand, there is a multiplication of assembly nodes because it is necessary to use one each time there is a shift in height of the connections between carrier posts and beams, which amounts to making the complexion more complex. building system and to increase the assembly time.

 Finally, most of these construction games do not allow large variations in the spacings of the ground bearing points, because of the impossibility of significantly varying the section of the beams and columns.

 In its essential application, the invention consists in the production of metal poles by assembly of steel products of common use, corniéres and / or flat irons.

 These angles and / or flat irons are assembled longitudinally with each other by small plates or crosspieces with mutti-merged wings welded together so as to present angulations which may be of 45, 600, 900, 1200, with respect to each other, and fear These small dishes or "braces" are bolted or welded at intervals between the angles and / or flat carbons.The latter are juxtaposed so that the post thus formed has, in the desiredections and on vertical gorges, spaces between two consecutive parallel flanges of the assembled flutes and / or flat irons, the width of which corresponds to the thickness of the small flats or flanges of the crosspieces constituting the assemblies (of the order of 2 to 3 cm). These grooves can pass the end of the me, vertical flat iron part, a I.P.N beam. or I.P.E. or any other profile whose end is in the form of a vertical flat iron.

 According to the section of these beams and, consequently, the thickness of their fime, will be interposed, on either side of the latter, wedges of varying thickness to fill the remaining space between two parallel wings and the beam core and the boulpnnage will be carried through the assembly without the intermediary of additional assembly part.

 The feet of the posts will be embedded on soles formed of metal plates, of variable dimensions according to the supported loads and the rate of stress of the grounds. On these plates, will be welded perpendicularly the types of braces that will fit into the interstices of the wings of the feet of the corresponding posts, with bolting of the wings on the "braces".

 In the case of enhancement of buildings, these same "braces" will also be used to ensure the vertical connection of two elements, posts of the same section, the ends of the wings of the two pole elements being bolted to the wings of the cross placed on the and other of the junction plan. The height of the connecting spider will depend on the height and section of the posts to be connected.

 These materials for the construction elements in accordance with the invention essentially include metals and more particularly ordinary steels. But according to the same principles and for different uses, we can make poles from wooden planks instead of flat irons.

 The posts are characterized by the number, thickness, width, spacing and angulation of their wings relative to each other and may be 450,900,600,1200, depending on the small dishes and / or "braces" assembly.

 The section of the angles and / or flat irons assembled will be chosen according to the loads to be supported, the height of the poles, the lengths of assembly to assure with the beams for the good held works. In certain cases and for the sake of economy, we will use angles with unequal wings and / or flat irons of different widths to make dissymmetrical poles, some assemblies with the beams not existing for certain directions or having to be more resistant in some directions than in others.

 But preference should be given to cruciform posts. As shown in Figure 1, the post is formed by the assembly of four equal angles wings (1) joined by small plates (2) bolted between the wings, alternately in one direction and then perpendicular to this direction.

 The pole in question makes it possible, among other things, to have horizontal (3) or inclined (4) beam splices of variable cross section in the four perpendicular directions, the most used in the building. These clashes are made by bolting the core (5) of the beams after interposition of metal shims on both sides (6).

 The seat of the post, independent, comprises a metal plate (7) on which is welded a spider (8) having two wings at right angles, in which is embedded the pole, the wings thereof being bolted to the transept.

The same type of brace (9) can be used to ensure the
Junction between two column elements in the case of elevation.

The section of this type of post resists buckling well in all directions, and in a comparable manner, & section almost equal to the profiles of common use used to work advantageously to compression, as shown in the table below .

Another type of column, interesting for the architectural composition is the column with braces and braces at 1280 allowing hexagonal frames (Figure 2).

As an example of the diversity of application of the invention, we may mention agricultural buildings with preferential ranges of 4.8 and 12 meters, but also craft or small industry buildings which often have extensions.
With poles made with wooden planks, let us mention the barracks or the evolutionary house.

 With small profiles made of iron, aluminum, stainless steel or copper, we can mention interior fittings such as shelves or bookcases.

 The flexibility of the system makes it possible to prefabricate these types of posts on a large scale for the inexpensive construction of scalable buildings. The prefabrication can also touch all the elements connected to it such as cantilevered cantilevered beams. make awnings or elements of cladding, floor, partition. . .etc, fixed between irons I, themselves bolted between posts (Figure 3).

 Entire buildings could be the subject of an office study and then be made of transportable elements and delivered and assembled on site as a construction game allowing all subsequent evolutions.
