Description

Technical Field

[0001] The utility model relates to the technical field of supporting platforms, in particular to a steel pipe connector for a temporary supporting platform, and in particular to a transverse steel pipe connector for a temporary supporting platform. Background Art

[0002] A temporary ground construction support platform usually refers to a temporary working platform or support structure built on the ground or a flat surface. In the construction of a temporary ground support platform, steel pipe connectors are often used to connect and fix the steel pipe frame structure. This frame structure can provide a stable support platform and carry the weight of workers, tools and materials.

[0003] Steel pipe connectors have strength and reliability, and can easily adjust the height and shape of the support platform through assembly and disassembly, which makes them one of the commonly used materials and tools for building temporary ground support platforms. However, the existing steel pipe connectors are relatively cumbersome to use, especially when the temporary support platform is assembled and disassembled at any time, the existing steel pipe connectors are inconvenient to use and do not have the advantage of quick assembly and disassembly. A transverse steel pipe connector suitable for quickly building a temporary support platform is proposed. Utility Model Content

[0004] In order to overcome the problem that the steel pipe connector used for temporary support platforms in the prior art is inconvenient to disassemble and assemble, the embodiment of the utility model provides a steel pipe connector for a temporary support platform. The technical solution is as follows:

[0005] The cam is an axially-coupled device for activating the engagement of the first and second guide rails, wherein the first and second guide rails are provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts.

[0006] Furthermore, a threaded hole is formed on an inner side wall of the slot away from the rotating sleeve, and the screw rod is arranged in the threaded hole.

[0007] Furthermore, an arc-shaped groove matching the first fixing sleeve and the second fixing sleeve is opened on one side of the bracket, and the first fixing sleeve and the second fixing sleeve are located in the arc-shaped groove. The arc-shaped groove is convenient for placing the steel pipe and makes the first fixing sleeve and the second fixing sleeve fixed on the bracket more firmly.

[0008] Furthermore, the rotating sleeve is a thin steel plate, the inner diameter of the rotating sleeve is slightly larger than the outer diameter of the steel pipe, and the opening of the rotating sleeve is slightly smaller than the outer diameter of the steel pipe. The steel pipe is forcibly inserted into the interior of the rotating sleeve from the opening, and the rotating sleeve can return to its original state to clamp the steel pipe.

[0009] Furthermore, a bottom rod is fixed to the lower end surface of the bracket, and the bottom rod can provide ground support for the support platform to enhance its stability.

[0010] Furthermore, the rotating sleeve is also in a "C" shape, and the rotating sleeve fits with the first fixed sleeve and the second fixed sleeve, so that the steel pipe connection operation is more labor-saving and the steel pipe connection is more stable.

[0011] Furthermore, the first fixing sleeve and the second fixing sleeve are symmetrically arranged at two ends of the bracket.

[0012] The beneficial effects of the technical solution provided by the embodiment of the utility model are as follows: the connecting piece has a simple structure, can be installed and disassembled at any time, and is relatively easy to use. It can quickly connect steel pipes when building a temporary support platform, saving time in building the support platform and improving construction efficiency. It also provides ground support for the steel pipe connection through the bottom rod, thereby enhancing the stability of the support platform. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] A threaded hole 11 is formed on an inner wall of the slot 9 away from the rotating sleeve 4 , and a screw rod 10 is disposed in the threaded hole 11 .

[0021] The rotating sleeve 4 is a thin steel plate, the inner diameter of the rotating sleeve 4 is slightly larger than the outer diameter of the steel pipe, and the opening of the rotating sleeve 4 is slightly smaller than the outer diameter of the steel pipe. The steel pipe is inserted into the rotating sleeve 4 from the opening, and the rotating sleeve 4 can return to its original state and clamp the steel pipe.
