Telescopic edge protective railing suitable for different spans

Abstract

The invention discloses a telescopic edge protective railing suitable for different spans. The telescopic edge protective railing comprises an end part vertical rod module, a cross rod module and a telescopic frame module, and is characterized in that the end part vertical rod module comprises two vertical rods; the cross rod module comprises an upper cross rod and a lower cross rod, each of the upper cross rod and the lower cross rod is formed by inserting an inner sleeve rod into an outer sleeve rod, the inner sleeve rod is provided with limiting holes at equal intervals, the outer sleeve rod is provided with limiting bolts, and the limiting bolts are inserted into different limiting holes for limiting and fixing; the telescopic frame module is installed in a square area defined by the two vertical rods, the upper transverse rod and the lower transverse rod, and comprises X-shaped supporting rods which are arranged in a crossed and hinged mode. The edge protective railing has transverse scalability, can adapt to edges with different lengths, avoids on-site cutting, can be used only by detaching the upper and lower detachable cross rods and tightening the telescopic frame module when not in use, can furthest shrink the area, achieves the effect of easy storage, and also achieves the purpose of repeated turnover use.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a retractable edge protection railing suitable for different spans. Background technique [0002] With the rapid development of the country's market economy and the acceleration of urbanization, land resources are decreasing day by day, and urban high-rise and super high-rise buildings are increasing. , human input, and technical input have all increased significantly. According to the safety and quality standards of the construction site, if the falling height is more than 2m (including 2m), and there is no protective facility on the edge or the wall is lower than 0.8m, the edge protective facility must be installed. [0003] The traditional border protection railings are made of fastener steel pipes and safety nets or stereotyped protection railings. The former is relatively rough in process and poor in stability, and it is difficult to meet the increa...
