Temporary structural parts for armrest

Abstract

The invention provides a temporary arrangement handrail component in a wedge mode having good construction property or strength, wherein the column inserting portion of the working platform is used to install the components of the handrail, comprising a horizontal section bar and an inclined section bar formed by the square end of the extended horizontal section bar towards the inclining direction, connecting components are arranged on the two ends of the horizontal section bar and the front end of the inclined section bar, which comprise, a grabber portion that can be inserted downwards in respect to the inserting portion, and a wedge portion penetrating the upper part of the grabber and inserted between the grabber and the inserting portion, in addition, the inclined section bar can engage the horizontal section bar in a rotating way.

Description

technical field [0001] The present invention relates to a temporary member for handrails installed on construction scaffolds or support frames (hereinafter collectively referred to as "scaffolds") such as frame-type scaffolds or small-scale scaffolds (worktops) for the purpose of preventing workers or equipment from falling. It also has the structure of diagonal braces for scaffolding. Background technique [0002] For example, in construction engineering, scaffolding and working frames are erected around the foundation, especially when building buildings with more than two floors, in order to prevent operators or equipment from falling accidents, handrails are usually provided on the scaffolding. [0003] Figure 14 A representative example thereof will be described. In the past, only handrails 70, 70 made of single tubes were installed between pillars 60 such as building frames of scaffolding 50, ... 60. Number 80 is a plate frame (a frame with a plate attached) for the ...

AI Technical Summary

Problems solved by technology

The first point is the problem of safety. In the past, handrails 70 were installed horizontally between pillars 60 and 60. Usually, only one or two handrails 70 were installed between the upper and lower plate frames 80 and 80. Therefore, the upper and lower sides of the handrails 70 There is a relatively large rectangular space 90, 90

And equipment etc. are easy to roll down from this space 90

[0005] The second point is about the strength of the scaffolding 50, that is, the handrails 70 in the past are often installed horizontally, so generally there are almost no braces (biased braces) that can perform functions such as reinforcing the scaffolding

There is a problem with noise
