Description

A kind of high-altitude edge protection safety railing for steel structure construction

technical field

The invention relates to the technical field of building construction, in particular to a high-altitude edge protection safety railing for steel structure construction.

Background technique

With the development of the national economy, more and more steel structure high-rise buildings, steel structure bridges, steel structure equipment, etc. have appeared. During the construction of high-altitude steel structures, construction workers often need to walk on the high-altitude platform and must walk on the edge of the steel platform. Set up high-altitude border guardrails to ensure the safety of high-altitude workers.

The traditional high-altitude protective railing for steel structure construction adopts the welding connection method with the steel platform. Although the welding connection method is firm and reliable, it has the following disadvantages: 1) The temporary railing is inconvenient to move. Because the temporary railing is welded with the steel platform, if the construction location If it is changed, it can only be re-fabricated and installed with a new temporary railing, or the original temporary railing can be cut and moved to a new location for welding, which is time-consuming and labor-intensive. 2) The temporary railing is welded to the steel platform. When the temporary railing is removed, the welding seam between the temporary railing and the steel platform needs to be cut off, and then the cutting part of the steel platform needs to be polished and painted, which wastes a lot of financial resources. . 3) Welding the temporary railings with the base metal of the steel platform will inevitably damage the performance of the original steel platform base metal and reduce the structural performance. In some important structures, the welding of temporary structures is not allowed. 4) After the temporary railing is cut, the railing column will be shortened, and the height of the temporary railing does not meet the requirements. These temporary railings are often scrapped or the vertical rails are re-lengthened, causing a lot of waste; these are all skilled in the art people do not want to see.
