PCT No. PCT/SE85/00175 Sec. 371 Date Dec. 13, 1985 Sec. 102(e) Date Dec. 13, 1985 PCT Filed Apr. 16, 1985 PCT Pub. No. WO85/04921 PCT Pub. Date Nov. 7, 1985.A joint between a vertically oriented hollow section column (1) and a horizontal load-carrying beam (3) in a two-story building structure such as an exhibition stand, which can be rapidly erected and dismantled, includes a straight core (2) fitted into the upper end of the column (1). The quadratic hollow section core (2) has a projecting bolt head (21) at the middle of either side surface. Each side wall of the generally quadratic hollow section column (1) has a central, axial slot (12) on its inside. On its underside the beam carries a dependent guide body, the width of which corresponds to the width of the internal column slot and is guided by this slot. The short end of the beam (3) has a vertically directed Tee slot (32,36) extending upwardly from the central area of the beam for accommodating the head and a portion of the shank of the screw on the core (2). A screening element (10) may be formed from the same section as the column (1) and is placed against the portion of the core (2) exposed along the height of the beam (3). |
