Abstract

A scaffold fastener is provided with a U-shaped grab body; the front part of the grab body is set to a pair of parallel arc-shaped grabs; slideway grooves are correspondingly arranged at the inner sides of two grab arms of the grab body; an arc-shaped clamping board with a concave surface facing the grab is arranged in the grab body; a lug body which is matched with the slideway groove is arrangedon the arc-shaped clamping board; a connecting plate with a threaded hold in the center is arranged at the rear part of the slideway groove between the two grab arms; an adjusting screw with a handleat the rear end is installed to be matched with the threaded hole in the connecting plate; the front end of the adjusting screw is rotatablely connected with the arc-shaped clamping board; and a grabbody tail-cuff is arranged at the rear part of the U-shaped grab body. The fastener has no use for a tool when in installation and dismantling, is convenient for operation, saves time and labor, andcan effectively enhance the erection and dismantling construction efficiency of a steel pipe scaffold; simultaneously, the fastener has the characteristics of compact structure, stable performance andgood processing technology performance, long service life and low production cost.

Description

technical field [0001] The invention relates to a scaffold component for building construction, in particular to a steel pipe scaffold fastener. Background technique [0002] At present, steel pipe scaffolding fasteners used in building construction are generally formed by connecting two buckle arc clips crossed by bolts. When this kind of fastener is used, it is necessary to use a wrench to turn the bolt to complete the fixing and dismounting of the steel pipe connection node of the scaffold, which is cumbersome to operate, time-consuming and laborious, and the construction efficiency is low. A previous patent application of the applicant with the application number "200820227722.0" provides a quick fastener for steel pipe scaffolding, which uses a locking screw equipped with a handle to control the movement of a secondary card body with an arc-shaped clamping plate at the front end. Move, complete the connection and removal of the horizontal and vertical steel pipe nodes ...
