Problems solved by technology

In the prior art, the lifeline column is clamped on the steel girder mostly by setting clamps on the flange plate of I-beam or H-beam, but the box-shaped steel girder has no cantilevered flange plate, so it is difficult to fix

Abstract

The invention discloses a lifeline column installation and fastening device suitable for box-shaped steel beams, comprising: a horizontal positioning plate, a limit right-angle plate and a fixed right-angle plate arranged in parallel on the bottom surface of the horizontal positioning plate, a horizontal positioning plate, The limiting right-angle plate and the fixed right-angle plate are sequentially connected to form a π-like structure, which is clamped on the box-shaped steel beam; the vertical faces of the limiting right-angle plate and the fixed right-angle plate are arranged facing each other; the limiting right-angle The horizontal plate surface of the plate is detachably connected to the plate surface of the horizontal positioning plate; the horizontal plate surface of the fixed right-angle plate is fixed to the horizontal positioning plate, and a pair of first screw holes are provided on the vertical plate surface. The first bolt passes through the first screw hole to fix the box-shaped steel beam; the edge of the horizontal positioning plate is provided with a clamping piece, which fixes the lifeline column to be installed to the horizontal positioning plate. The invention has the beneficial effects that the lifeline column can be detachably connected with the box-shaped steel beam, can be used repeatedly, and has strong practicability.

Description

technical field [0001] The invention relates to the field of installation and fastening of a lifeline column. More specifically, the present invention relates to a lifeline post installation fastening device suitable for box-shaped steel girders. Background technique [0002] In the construction process of building steel structures, in order to ensure the safety of workers working at heights, it is necessary to set up lifeline protection on the steel beams. The traditional method is to weld the connection plate on the box girder, and fasten the lifeline column and the connection plate with clamps, or The lifeline pole is welded directly to the top of the box girder. This technology requires hot-fire welding on finished steel components, which will cause certain damage to the base metal and affect the quality of the base metal and structural safety. After the lifeline column was removed after construction, it was necessary to perform hot-fire cutting on the connecting plate...
