Embodiment Construction

[0057] Figures 1A, B, C and D show the method of bending a truss web 1, 4 according to the invention, the geometry being depicted.

[0058] Initially, a straight web (FIG. 1A) is provided with end bends 2, 2'. Its ends are bent down approximately 180 degrees (FIG. 1B). The web is then bent again symmetrically around the straight section at the center of the rod, with the end pieces mirrored upwards approximately 110 degrees (Fig. 1C) until the hook-like ends of the web intersect each other (Fig. 1D).

[0059] The web is now triangular in shape and when the ends 1, 4 overlap each other, an upper corner is formed. The end bends are arranged so that the two bends 2, 2' together form a ring of sufficient size, seen in the triangular plane, to fully accommodate the longitudinal stiffener 6 and to allow casting in the chord.

[0060] Figure 2 shows a perspective view of truss webs 1, 4 according to the invention, assembled as truss girders and connected to longitudinal stiffeners ...

Abstract

A truss web (1, 4) for reinforcing a truss girder (15) to a slab (9) of a construction element with at least one cast chord (8). A beam web member assembly (1, 4) forming a truss web made of bent rods, placed diagonally, when viewed in the longitudinal direction of the chord, fastened to the chord in the element and board. The truss webs (1, 4) are made by bending the bar sections into a triangular-like shape and have end hooks (2, 2') at both ends while bending symmetrically around the straight middle of each web to each other mirrored so that the straight ends of the webs intersect each other at one corner of the triangle. The ends are oriented adjacent to each other and twisted so that the end hooks (2, 2') form a loop into which the stiffener (6), with respect to the longitudinal direction of the chord (8), can be inserted and said end hooks Casting takes place in the chord (8).

Description

technical field [0001] The invention relates to an arrangement method of truss chords. Background technique [0002] The present invention is a further improvement of Swedish patent SE 502302 E04C 3 / 293 PCT SE 94 / 00700. Involves an arrangement of beams or building elements, particularly truss webs, as shown in Figures 21A-B and 22A-D. [0003] The invention according to this patent allows the casting of chords into reinforced truss beams in building elements, while also casting unit slabs (slabs) as separate elements to handle the load-bearing handling required of pre-cast beams and to speed up the entire construction process. [0004] The patent works well. [0005] Using previous inventions, we have succeeded in making building elements faster, longer and stronger than before, without deflection issues. Plumbing, electrical and other utilities can also be installed relatively quickly within the building elements. Circulating hot indoor air also creates soft, warm floo...
