Scaffold cross rod connector and production process thereof

Abstract

The invention discloses a scaffold cross rod connector which comprises a connection pin, a positioning fixing connector. The connection pin is formed by tightly adhering two metal pieces along a Z-shaft, the positioning fixing connector and the connection pin are integrally formed, and the positioning fixing connector comprises two connecting reinforcement ribs formed by the metal pieces extending along the Z-shaft upwards and further comprises two butterfly positioning pieces symmetrically distributed along the Z-shaft. The butterfly positioning pieces and the connecting reinforcement ribs are reversely bent around the Z-shaft and integrally formed, and the inscribed circles or inscribed ovals of the two butterfly positioning pieces are matched with inner holes of a cross rod. The invention further discloses a production process of the scaffold cross rod connector. The scaffold cross rod connector and the production process are suitable for scaffolds in the building industry.

Description

Technical field [0001] The invention relates to a scaffold crossbar joint, and also relates to a production process of the scaffold crossbar joint. Background technique [0002] In the prior art, the joint of the scaffold cross bar is welded to the end of the scaffold cross bar and then plugged into the buckle plate of the vertical pole, see figure 1 , Scaffolding includes horizontal bar 3, vertical bar 2, and vertical bar 2 with N buckle plates 1, N ≥ 1, see figure 2 , The buckle plate 1 has a central through hole 11; four positioning buckle holes 12 are symmetrically distributed around the central through hole 11 on the disc body. See image 3 , The cross bar 3 with the joint 31 can be inserted into the positioning buckle hole 12 of the buckle plate 1 through which the central through hole 11 and the vertical bar 2 are fixed to each other. During installation, first, the cross bar 3 moves the joint 31 in the direction of arrow A above the corresponding positioning button hole ...

AI Technical Summary

Problems solved by technology

During installation, firstly, the cross bar 3 moves the joint 31 to the top of the corresponding positioning button hole 12 of the buckle plate 1 along the direction of the arrow A, and then inserts it into the positioning button hole 12 along the direction of the arrow B, that is, the horizontal bar 3 and the vertical joint are realized. Connection for rod 2; see Figure 4 , the connection between the joint 31 and the cross bar 3 is fixed by welding and fixing the end of the cross bar 3 by the cylindrical top 311 of the joint. Since the cylindrical top 311 is larger than the outer diameter of the cross bar 3, the pedals are laid on the scaffolding. It is necessary to avoid the cylindrical top 311 when storing, which also affects the neat stacking of the horizontal bars
