Steel pipe scaffold connection socket

Abstract

The invention discloses a steel pipe scaffold connection socket which is an overall-hollow cross cone-shaped connection socket formed from a metal tubular blank by virtue of die extrusion processing. The center of the connection socket is an axial round hole matched with the outer diameter of a scaffold vertical rod; four axial square holes with the same size are communicated with the axial round hole and uniformly distributed around the axial round hole; two opposite side surfaces of each axial square hole are vertical planes parallel to each other; the far-end side surface, relatively away from the center of the connection socket, of each axial square hole is an inclined plane inclining toward the inner side from top to bottom; and the slope of the inclined plane is equal to that of the inclined plane of a wedge plug on a scaffold cross rod. In the steel pipe scaffold connection socket disclosed by the invention, the forming technology is simple, a small quantity of materials is used, the connection socket is light, and the production cost is low; the socket is good in toughness and rigidity and strong in bearing capacity; the socket is fixedly connected with the plug, the operation is simple and convenient, and the contact area is large; and the socket is in close fit, has less possibility of getting loose and is good in connection stability.

Description

technical field [0001] The invention relates to scaffolding for building construction, in particular to a steel pipe scaffolding connection socket. Background technique [0002] The performance of steel pipe scaffolding depends to a large extent on the performance of the joints between the vertical rod and the horizontal rod. Bolt fastening joints of vertical poles and crossbars are commonly used in current building construction. The problems with this type of joint joints between vertical poles and crossbars are: ①The joints are scattered and easy to lose; ② The rods at the joints are eccentrically connected, and the load is transmitted by friction, thus reducing its load capacity; ③The joint connection and fixing operations are troublesome, and the joint quality is not only affected by the quality of the parts themselves, but also by the quality of the workers The impact of the node connection quality is difficult to control. The plug-in plug-in type connection node betw...

Problems solved by technology

Bolt fastening joints of vertical poles and crossbars are commonly used in current building construction. The problems existing in this kind of joint joints of vertical poles and crossbars are: ①The joint joints are scattered and easy to lose; ② The rods at the joints are eccentrically connected, and the load is transmitted by friction, thus reducing its load capacity; ③The joint connection and fixing operation is troublesome, and the joint quality is not only affected by the quality of the parts themselves, but also by the quality of the workers The impact of the node connection quality is difficult to control

However, the inserts in the prior art use casting inserts or steel stamping inserts. The cast inserts have low toughness, brittleness, and poor performance when subjected to sudden loads; material waste is serious during the forming process of steel plate stamping inserts, and rigidity is also low. It is slightly insufficient. At the same time, both the casting insert and the stamping insert have the problems of complex molding process, high manufacturing cost, small contact area between plug and insert, and poor connection stability.
