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 arranged on 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 handle at 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 grab body 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, and can effectively enhance the erection and dismantling construction efficiency of a steel pipe scaffold; simultaneously, the fastener has the characteristics of compact structure, stable performance and good processing technology performance, long service life and low production cost.

Description

Scaffold clasp

Technical field

The present invention relates to the building operations assembly for scaffold, be specifically related to a kind of steel tube scaffold clasp.

Background technology

At present, the steel tube scaffold clasp that building operations is used generally adopts two make-up circular arc fasteners of right-angled intersection to constitute by the bolt connection.This kind fastener needs just can finish with the spanner rotating bolt the fixing and dismounting of scaffolding steel pipe connected node in use, and troublesome poeration is wasted time and energy, and efficiency of construction is low.The applicant's application number provides a kind of steel pipe scaffold PUSH NUT FASTENERS for a patent application formerly of " 200820227722.0 ", it adopts the locking leading screw that is equipped with handle to control the moving of pair card body that a front end is provided with the arc clamp, and the connection and the dismounting of the horizontal, vertical steel pipe node of scaffold finished in the cooperation that is provided with the main card body of parallel grab by pair card body and front portion.This kind scaffold clasp is owing to need tool using to finish to install and dismantling operation, has easy to use, operation time and labour saving, can effectively improve the advantage that operating efficiency was built and removed to steel pipe scaffold.But this steel pipe scaffold PUSH NUT FASTENERS is aspect functional performance, processing characteristics and product cost reduction, still requires further improvement and perfect.

Summary of the invention

The objective of the invention is at the problems referred to above, the scaffold clasp that a kind of functional performance and process industrial art performance are better, be more convenient for reducing the production cost is provided.

The technical scheme that realizes above-mentioned purpose is: a kind of scaffold clasp, it has a U-shaped grab body, the arc grab of pair of parallel is arranged in the front portion of this grab body, the inboard corresponding slideway groove that is respectively arranged with at U-shaped grab body two clamping hook arms, in U-shaped grab body, become mutual plumbness to be provided with the arc clamp of a concave surface towards grab with the arc grab, the both sides at this arc clamp middle part are respectively arranged with the lug body that matches with the slideway groove, the rear that is positioned at the slideway groove between two clamping hook arms becomes mutual plumbness to be fixed with a plate with clamping hook arm, the center of this junction plate plate face is provided with screwed hole, pass the through hole of U-shaped grab body rear end and match and be provided with an adjustment leading screw parallel with clamping hook arm with screwed hole on the junction plate, the front end of this adjustment leading screw becomes to be rotatably connected with the arc clamp, is connected with handle in the rear end of adjusting leading screw.

Technical scheme of the present invention also comprises: be equipped with a grab body tail cover at the rear portion of U-shaped grab body; The anterior arc grab that is provided with of described U-shaped grab body is the circular arc grab, and the arc clamp is the circular arc clamp.

The present invention has following advantage:

Do not need tool using when 1, mounting and dismounting, easy to operate, saving of work and time can effectively improve the efficient that work was built and removed to steel pipe scaffold.

2, the Stability Analysis of Structures performance is good, reliable lock, long service life.

3, compact conformation, process industrial art performance is good, helps reducing the production cost.
