Description

TECHNICAL FIELD

[0001] The utility model relates to high -rise building construction protection technical field, concretely relates to a high -rise building steel structure overhanging net mounting structure. BACKGROUND

[0002] With the social development, the demand of land resource utilization rate is rising, and the demand of high -rise building construction also increases. Most high -rise buildings adopt steel frame-reinforced concrete core tube hybrid structure lateral force resisting system, and small appliances such as bolts and wrenches are likely to fall from high altitude in the outer frame construction process, which causes damage to the personal safety of the personnel around the construction site. Using overhanging net as a safety protection measure can not only effectively reduce the occurrence of safety accidents, but also play a certain aesthetic role.

[0003] When installing the overhanging net on the high-rise building steel structure, the clamp is usually installed on the flange of the steel beam, but since the steel truss floor slab needs to be laid on the flange of the steel beam, the clamp on the flange of the steel beam will affect the subsequent installation of the steel truss floor slab.

[0004] The utility model patent with application number 202321869311.2 discloses a high-rise building overhanging net mounting structure, which quickly connects the bottom of the overhanging net and the lower flange of the lower steel beam by using the lower clamp and the sleeve pipe with connecting ears. Specifically, the U-shaped base is fastened to the lower flange of the lower steel beam, the sleeve pipe is sleeved into the connecting vertical rod, and the connecting ears are connected with the connecting holes of the overhanging net by using bolts or pins. This way of connecting the bottom of the overhanging net and the lower flange of the lower steel beam by using the lower clamp and the sleeve pipe can facilitate the quick installation of the overhanging net, increase the stability of the overhanging net as a whole, and effectively resist external forces to ensure safety and stability. Compared with connecting the overhanging net with the upper flange of the lower steel beam, this way of the utility model will not affect the installation of the steel truss floor slab. However, when assembling the overhanging net around the high-rise building steel structure by using the structure in the utility model, multiple structures, i.e. multiple mounting nets, are needed to splice together. When the installation angles of the overhanging nets are inconsistent, there will be gaps between the adjacent overhanging nets, and falling objects from high altitude may still fall from the gaps between the adjacent two overhanging nets. Therefore, there is still a risk of using this structure. UTILITY MODEL CONTENTS
