Definitions

  • the present invention relates, in general, the realization of large spans such as those encountered in what is known as "large areas" and in industrial halls by the combination, on the one hand , preferably glulam beams, or composite materials, and excluding metallic or concrete materials, of long span constituting the parallel sides of the meshes with conventional crosspieces and, on the other hand, of a frame support metal.
  • the present invention relates to the support and attachment system for long-span beams made of glulam or composite materials, on metal support posts, a system arranged so as to allow the vertical reaction to be transferred from the weight of the beam in a pushing effort in the corresponding post and thus create, in the beam, a horizontal force of longitudinal stress which results in increasing the possible span of said beam.
  • each post is provided with at least one bracing leg articulated at its lower end on a hinge pin secured to the corresponding post and the upper end of which is provided with a receiving angle iron on which comes a corner end piece integral with the end of a long-span beam, by means of contact parts with which said end piece is provided, whereby the vertical reaction of the weight of the beam is transferred in a bracing effort in the axis of the corresponding leg, which effort creates a horizontal effort of longitudinal stress in the corresponding long span beam.
  • the invention relates more particularly to the improved support and attachment system for beams 1 A, 1B, 1 C ... on the corresponding posts 2A, 2B, 2C ...
  • each support system has a double support hub, namely: 3A 1 , 3A 2 for the post 2A and the beam 1A; 3Bi, 3B 2 for the column 2B and the beams 1 B and 1 A, 3C 1 , 3C 2 for the column 2C and the beams 1 C and 1 B; and so on until the last edge post (not shown) which is at the other end of the aligned beams.
  • each system is arranged so as to allow the vertical reaction of the weight of the beam to be transferred in a pushing effort on the corresponding post and to create thus, in said beam, a horizontal force of longitudinal stress which results in increasing the maximum possible span of a beam of this type.
  • the system is consisting, symmetrically with respect to the longitudinal axis of symmetry XX of the post, in this case 2B, of two identical arch legs 4 1 , 4 2 articulated at their lower end, on an axis 5 1 , 5 2 pinned on post 2B, without there being any friction or moment, and to which we will return in detail later.
  • These legs are also provided, at their upper end, with support angles 6 1 , 6 2 .
  • end angles 7 1 , 7 2 are fixed for example by gluing, bolting or riveting, on the lower corner of the corresponding beams 1B, 1 A, these angles comprising contact parts 8 1 , 8 2 with the corresponding angles 6 1 , 6 2 .
  • anti-buckling reinforcement plates such as for example the side plates 13A and 13B on the leg proper and the plates 14A and 14B on the wings of the post.
  • Figures 7 and 8 show on a large scale the preferred embodiment of the invention.
  • the end of the beam 1 B is provided with an end piece 7 1 in the form of an angle iron, each of the wings of which is provided with a contact cylinder or half-cylinder 8 1 which comes to bear on the corresponding element. 6 1 of the support angle welded to the upper end of the arch leg 4 1 .
  • the horizontal stress thus created in the beam 1 B makes it possible, as we have seen previously, to increase the maximum possible span of said beam.
  • the automatic catching up of the aging of the material constituting the beam will take place over time, preferably preferably glulam or composite materials such as woven polyester, tubes, fibers, etc. excluding metal and concrete.
  • the end piece 7 1 has only one large-radius contact cylinder resting on the two wings of the angle iron 6 1 of the bracing leg, but, again, this solution would have difficulties in fixing the single cylinder to the end piece and controlling the support distances for both vertical Rv and horizontal forces R H.
  • the post 2B is extended towards the high and is provided at the head (see FIGS. 2 and 3) with two anti-spill beams 15A, 15B which are riveted in their center on the wings of the post 2B with an H section, from which laterally enclose the heads of the beams 1B and 1A placed in the extension of one another.
  • these same beams can be joined by plates such as 16A, 16B and ser support for equipment, such as air conditioning, heating or others.
  • the angle e which the arching leg 4 1 must make with respect to the vertical axis of symmetry XX of the post 2B is determined as a function of the characteristic data of the constituent elements (beams, posts, minimum height under the ceiling, etc. ..) of the long-range construction to be carried out.
  • Mathematical theory would like the center of gravity of the long span beam 1B, the geometric center of the end piece 7 1 with which said beam is provided, as well as the geometric center of the joint 5 1 on the post 2B to be placed on a same arc.
  • the angle 8 should be between 30 ° and 60 ° and preferably, since it is much simpler, from a practical construction point of view, equal to 45 ° .
  • the edge posts such as for example the post 2A of FIGS. 1 and 9 for which the horizontal effect of stress R H which occurs in part 1A and which is transferred into an effect d the Rp buttress on the post 2A is not balanced by the symmetrically reverse action of another beam as is for example the case with the post 2B, must be compensated here by a brace strut 3A 2 which is riveted at its upper end to the wings of the post 2A and is arranged in the extension of the arching leg 3A 1 to come to bear by its lower end on the ground as it appears clearly in FIG. 1. The whole is thus perfectly balanced.
  • the invention proposes an improved system making it possible to ensure the support and the attachment of long-span beams of glulam or composite materials on metal support posts comprising, on each post, at least one leg d buttress arch articulated at its lower end to said post and by which one end of a long-span beam is supported by the post, contact pieces arranged on the beam or at the upper end of the bracing leg , and support elements arranged at the upper end of the bracing leg or on the beam on which the contact parts come to bear, the arrangement of these contact parts and these support elements being such that the weight of the beam produces a longitudinal compressive force along the axis of the leg, which produces a longitudinal compressive force on the beam.
