Embodiment Construction

[0015] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0016] figure 1 , figure 2 and image 3 A steel pipe joint for scaffolding shown has a lower clamp 1 and an upper clamp 2, the upper clamp 2 is arranged in parallel directly above the lower clamp 1, and the lower clamp 1 and the upper clamp 2 are arranged symmetrically by two The semi-circular edging 3 is composed of the inner surface of the edging 3 provided with a non-slip pad 8, so the inner wall surface of the anti-slip pad 8 is in a zigzag shape to increase the coefficient of friction with the steel pipe, which has a good anti-slip effect. One end of the symmetrically arranged semicircular hemming 3 is movably connected by a pin shaft 10, and the other end is provided with mutually symmetrical flanging joints 4, and the said flanging joints 4 are provided with threaded holes 5, and the symmetrically arranged flanging joints 4 The bolts 6 are fi...

Abstract

The invention relates to a steel pipe joint for scaffolding, which has a lower chuck and an upper chuck. Both the lower chuck and the upper chuck are composed of two symmetrically arranged semicircular wrappings, and one end of the wrapping is movable through a pin shaft. connection, the other end is provided with a flanged joint, and the flanged joint is provided with a threaded hole, and a bolt is connected in the threaded hole; the lower chuck and the upper chuck are connected by a line spacing adjustment rod, wherein the upper chuck A tooth-shaped positioning block is arranged between the symmetrically arranged flanging joints, and the tooth-shaped positioning block is provided with a tooth-shaped surface, and a tooth-shaped adjusting surface matching the tooth-shaped surface is provided on the side of the line distance adjusting rod corresponding to the tooth-shaped surface. This kind of scaffolding steel pipe joint has a simple structure and consists of two chucks. The chucks are adjusted up and down through the interconnected line spacing adjustment rods, so that different parts of the two butt steel pipes can be connected to ensure the stability of the connection between the steel pipes. Improve the security effect.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a scaffold steel pipe joint. Background technique [0002] Scaffolding refers to various supports set up on the construction site for workers to operate and solve vertical and horizontal transportation. The generic term on building circle, refers to building site be used in the higher place that cannot directly construct of exterior wall, interior decoration or floor height. It is mainly for construction workers to work up and down or for peripheral safety net enclosures and high-altitude installation components. Some projects also use scaffolding as a template, and it is also widely used in advertising, municipal administration, traffic roads and bridges, mines and other departments. [0003] In order to facilitate the disassembly and reuse of the scaffolding made of steel pipes, the steel pipes are fixedly connected by connecting pieces. This connecting piece is also made of...
