Novel steel tube scaffold

Abstract

The invention discloses a novel steel tube scaffold. A vertical tube is connected with a horizontal plane transverse tube, a horizontal plane longitudinal tube, a horizontal inclined tube and a vertical inclined tube through a connecting piece; the connecting piece comprises a sleeve and vertical tube joints; four trapezoid keys uniformly distributed along the circumference are arranged on the peripheral surface of the sleeve; the two ends of each vertical tube joint are provided with an annular insertion platform and a trapezoid groove respectively; the trapezoid keys are inserted into the trapezoid grooves; through holes which are formed vertical to length directions of the trapezoid keys and the trapezoid grooves are formed on the middle parts of the length directions of the trapezoid keys and the trapezoid grooves, and pass through the two sides of corresponding vertical tube joints; lock pins are arranged in the through holes; the sleeve is welded on the vertical tube; the annular insertion platforms of the vertical tube joints are welded with the horizontal plane transverse tube or the horizontal plane longitudinal tube; and one end or two ends of each lock pin are connected with the horizontal inclined tube or the vertical inclined tube. The invention has the advantages that: the horizontal inclined tube and the vertical inclined tube are connected with the vertical tube joints and the trapezoid keys of the sleeve through the lock pins; simultaneously, the vertical tube joints are mutually fastened with the sleeve, so that the vertical tube joints are effectively prevented from being separated from the sleeve.

Description

technical field [0001] The invention relates to a novel steel pipe scaffold used in the construction field. Background technique [0002] The connectors of the new steel pipe scaffolding in the prior art mainly include a sleeve and a vertical pipe joint. Four trapezoidal keys evenly distributed on the original circumference are arranged on the outer peripheral surface of the sleeve; rings are respectively arranged at both ends of the vertical pipe joint. A shape socket platform and a trapezoidal groove matched with the trapezoidal key, and the trapezoidal key is inserted into the trapezoidal groove. When in use, put the sleeve on the standpipe and weld it, and connect the ring-shaped socket platform of the vertical pipe joint with the top of the horizontal pipe and the top of the longitudinal pipe. The trapezoidal key can be inserted into the trapezoidal groove, which is very convenient. But this connector also has the following disadvantages: although the connection metho...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to provide a new type of steel pipe scaffolding to solve the problem that the trapezoidal keys inserted into the trapezoidal grooves in the prior art may cause the two to be separated in case of external force, which may cause potential safety hazards; Tube connectors, which limit the range of applications
