<p>The invention relates especially to an assembly of two beams (3) and of two purlins on a vertical column (2) of square cross-section, for producing a building structure in which the two beams are aligned on top of the said column and the two purlins are also aligned on top of the said purlin, orthogonally to the line of the beams. This assembly is characterised in that the top of the column comprises four horizontal brackets (24, 25) and four recesses (28, 29) which open upwards and are made so that each overhangs a bracket, in that each bracket is provided with a metal plate (26, 27), in that the ends (47) of the beams (3) and of the purlins each comprise at least one metal shoe (54) and at least one metal flat (45), which are flush with the horizontal faces (55, 49) of the end (47) of the said beam or purlin, in that the recesses, and respectively the plates, are vertically offset in pairs, in that each of the shoes (54) is laid and fixed to the plate of the bracket of the column which is intended for it, in that at least a first continuity bar (60) welded onto the flats (45) of the beams traverses the column at the level of the deep recesses (28), and in that at least a second continuity bar (160) welded onto the flats of the purlins traverses the column at the level of the shallower recesses (29), the said two bars being additionally caulked on the column by pouring a concrete (62). Applicable to the production of a building structure in which the column, the beams and the purlins are made of reinforced concrete. <IMAGE></p> |
