Description

Technical Field

[0001] This utility model belongs to the field of steel structure buildings, and specifically relates to a protective structure for the side partition wall of a steel structure ladder. Background Technology

[0002] Compared to traditional concrete buildings, steel structure buildings use steel plates or profiles instead of reinforced concrete, resulting in higher strength and better earthquake resistance. Furthermore, because components can be factory-fabricated and installed on-site, construction time is significantly reduced. The reusability of steel also greatly reduces construction waste, making it more environmentally friendly.

[0003] Currently, in steel structure public buildings, the steel structure staircase structure can refer to the patent with announcement number CN110306741A. The steel structure staircase includes inclined support steel beams, several support columns welded vertically to the inclined support steel beams, and step horizontal plates welded horizontally to the top of the columns.

Therefore, it is necessary to set up a partition wall on the side of the steel ladder away from the building wall. Due to its height, the conventional method of setting up top and bottom joists and vertical secondary joists has the disadvantages of high construction difficulty and poor structural stability.
