Self-locking fast-assembly scaffold and lap joint method

Abstract

The invention discloses a self-locking fast-assembly scaffold and a lap joint method, and relates to the field of scaffolds. The self-locking fast-assembly scaffold comprises main pipes and a horizontal pipe, wherein connecting pipes are arranged at the bottoms of the main pipes, fixing frames are arranged on the outer sides of the main pipes, fixing rods penetrating through the main pipes are slidably connected into the fixing frames, linkage pieces are arranged on the outer sides of the fixing rods, and springs are arranged between the linkage pieces and the fixing frames. According to the scaffold, the main pipes and the connecting pipes are vertically and coaxially connected, so that after the upper pipeline is stressed, the stress can be coaxially and vertically transmitted to the lower pipeline, and excellent stress transmission is kept; and a fixed hoe is inserted into a connecting sleeve for primary connection, a bayonet lock obliquely extends out of the bottom of the fixed hoe by hammering the bayonet lock from top to bottom after connection, and the fixed hoe abuts against the extending bayonet lock to enable the bayonet lock and the connecting sleeve to form a self-locking state, so that reinforcement is quickly and easily completed.

Description

technical field [0001] The invention relates to the field of scaffolding, in particular to a self-locking quick-installation scaffolding and a lapping method. Background technique [0002] Scaffolding is a work platform set up to ensure the smooth progress of each construction process. It can be divided into outer scaffolding and inner scaffolding according to the erection position; it can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding according to different materials; it can be divided into vertical pole type according to the structure. Scaffolding, Bridge Scaffolding, Portal Scaffolding, Suspension Scaffolding, Hanging Scaffolding, Picking Scaffolding, Climbing Scaffolding. [0003] Existing scaffolds mostly use seamless steel pipes as the main material. According to different requirements, there are various diameters. The connection methods include disc buckle, bowl buckle and other connection methods. Flexible, the bowl buckle type is...

AI Technical Summary

Problems solved by technology

[0005] Based on this, the purpose of the present invention is to provide a self-locking quick-installation scaffold and a lapping method to solve the problem of easy shaking at the insertion joint of the existing scaffolding bowl-buckle scaffolding pole, poor force of the disc buckle type, and horizontal rod pin. The reinforcement of the sheet is laborious, easy to loosen and fall off, the final installation of the handrail has potential safety hazards, and the technical problems of scissor support installation are time-consuming
