Connecting piece for stair edge protection

Abstract

The invention relates to the technical field of building construction, and discloses a connecting piece for stair edge protection, which comprises a handrail vertical rod arranged at the edge of a stair, the bottom of the handrail vertical rod is sleeved with a vertical rod sleeve, the outer wall of the vertical rod sleeve is fixedly connected with a reinforcing steel bar sleeve, an embedded reinforcing steel bar is inserted into the reinforcing steel bar sleeve, and the embedded reinforcing steel bar is fixedly connected with the vertical rod sleeve. The embedded steel bars are arranged on the edge of the stair. When the handrail vertical rods are installed, the embedded steel bars are sleeved with the steel bar sleeves and fastened through the first fastening bolts, then the bottoms of the handrail vertical rods are inserted into the vertical rod sleeves, and then the handrail vertical rods are fastened through the second fastening bolts, so that installation is very convenient, and the handrail vertical rods are connected with stairs and floors of a building structure ingeniously according to the clamping type physical principle; the handrail vertical rod has the advantages of being simple in structure, convenient to construct and firm in connection.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a connecting piece for edge protection of stairs. Background technique [0002] With the rapid development of the market economy and the acceleration of urbanization, land resources are decreasing day by day, and urban mid-rise and super high-rise buildings are increasing day by day. In order to ensure construction safety, more attention should be paid to the safety protection of the marginal parts during the construction process. [0003] At present, the commonly used safety facilities at the stairway and the stairway on the construction site are guardrails built with steel pipes and various fasteners. The poles are generally fixed in the following two forms: First, the traditional construction must start from the bottom Install the pole until the top floor, and install a small crossbar on the rest platform and the floor to withstand the wall to fix the pole; the ...

AI Technical Summary

Problems solved by technology

[0004] Among the above two methods, the first installation method is not only cumbersome to install, it takes up space on the platform and the floor, but also has rough workmanship and poor stability. When the operator operates and walks in the stairway, it is easy to cause clothing entanglement and collision injuries. , it is difficult to meet the safety protection requirements. The steel pipes and fasteners used are large in quantity and high in cost. There are different degrees of disadvantages in the fixing of poles. The commonality is mainly manifested in the process of paving the floor tiles in the later stage of decoration. In the process of ground construction, the edge protection of the stairs needs to be removed. Since this stage is the empty window period for the formal handrail installation, so In the process of ground decoration, the edge protection of the stairs is missing, and there are serious safety hazards
