Self-locking type scaffold fixing device

Abstract

The invention provides a self-locking type scaffold fixing device, which is used for fixedly connecting a horizontal-transverse bracket rod, a vertical-oblique bracket rod and a vertical rod. The self-locking type scaffold fixing device comprises a socket base, a locking piece and a fixed piece, wherein the socket base comprises a sleeve body part, a first locking head part and a second locking head part; the sleeve body part is provided with a ring-shaped opening and is used for being sheathed on the vertical rod; the first locking head part and the second locking head part extend to one side from the two ends of the opening of the sleeve body part, and are arranged oppositely; and the locking piece penetrates through and locks the first locking head part and the second locking head part. The self-locking type scaffold fixing device provided by the invention has the advantages that the locking positions of the socket base on the vertical rod can be conveniently adjusted, so that the trouble of welding is avoided, the multi-angle and multi-position connection between the vertical rod and the horizontal-transverse bracket rod as well as the vertical-oblique bracket rod is realized, the structure is simple, and the construction materials and the assembling-disassembling time are saved.

Description

Technical field [0001] The invention relates to the technical field of building components, in particular to a self-locking scaffold fixing device. Background technique [0002] At present, there are many steel pipe scaffolds used on construction sites, and many new steel pipe scaffolds have been born, especially tool scaffolds. The scaffold steel pipe supports are welded on the poles with socket bases, and by setting four-way trapezoidal cones and The method of connecting the cross bar trapezoidal groove realizes the erection of the steel pipe support. This type of steel pipe support has the characteristics of simple structure, quick assembly and disassembly, safety and stability, and economic efficiency. [0003] However, the connecting device of the above tooled scaffolding is a shaped steel casting. In actual use, it must be fastened to the fixed size position of the vertical pole by welding, and then passed through the trapezoidal taper on the connecting device. The method of...

Problems solved by technology

[0003] However, the connecting device of the above-mentioned tooled scaffolding is a stereotyped steel casting. In the actual use process, it must first be fastened to the fixed size position of the vertical pole by welding, and then through the trapezoidal cone head on the connecting device. The method of connecting with the trapezoidal groove of the crossbar realizes the erection of the steel pipe support. Although this method of modulus and length is in line with the trend of scaffolding tooling, this tooling scaffolding cannot temporarily weld the socket base on the pole. , when the scaffold needs to temporarily add a connected horizontal bar or horizontal bar on the vertical bar, this function cannot be realized flexibly, thus limiting the use of this type of scaffolding

[0004] In addition, the trapezoidal conical head on the connecting device of the tooled scaffold can be plugged into the horizontal bar and the trapezoidal groove at one end of the horizontal bar, but it cannot be effectively connected with the vertical bar, which limits the Application of similar scaffolding in the construction of high formwork support that needs to provide vertical slanting rod support
