Scaffold crossbar joint and production process thereof

Abstract

The invention discloses a scaffold crossbar joint. The scaffold crossbar joint comprises a bent frame sheet and a nested vertical sheet. The bent frame sheet consists of a top surface, a bottom surface and a frame side which are integrated to enclose a rectangular frame. The top surface is provided with an upper bolt hole, the bottom surface is provided with a lower bolt hole, and the upper bolt hole and the lower bolt hole are coaxial. The nested vertical sheet is perpendicular to the bottom surface and the top surface and nested into the bent frame sheet, two ends of the nested vertical sheet are respectively integrally welded with the top surface and the bottom surface, and the middle of the nested vertical sheet is provided with a nested notch perpendicular to and distant from the frame side. The invention further discloses a production process of the scaffold crossbar joint. The scaffold crossbar joint and the production process thereof are applicable to scaffolds in the construction industry.

Description

technical field [0001] The invention relates to a scaffold cross-bar joint, and also relates to a production process of the scaffold cross-bar joint. Background technique [0002] In the prior art, after the joints of the cross-bar of the scaffold and the ends of the cross-bar of the scaffold are welded as one, they are plugged into the buckle plate of the vertical pole, see figure 1 , the scaffolding includes tie rods 3, vertical rods 2, and vertical rods 2 are distributed with N buckle discs 1 at intervals, N≥1, see figure 2 The buckle plate 1 has a central through hole 11; four positioning button holes 12 are symmetrically distributed on the disc body around the central through hole 11. see image 3 , the tie rod 3 with the joint 31, the vertical bar 2 that can be inserted into the central through hole 11 to be fixedly connected to each other, the joint 31 has a caulking 311, and the thickness of the buckle plate 1 is adapted to the opening of the caulking 311. When i...

Problems solved by technology

[0003] In the above-mentioned technical scheme, it is necessary to consider that the opening of the socket 311 of the joint 31 is compatible with the thickness of the buckle plate 1, and that the size and strength of the welding between the joint 31 and the cross bar 3 are matched, so that the overall size of the joint 31 is compared to The opening size of the socket 311 is relatively large, that is, the joint 3 is very thick, and the joint 31 is generally made of metal castings. The sand holes and pores that cannot be avoided in castings are safety hazards
