Description

Technical Field

[0001] The utility model relates to the technical field of connecting members between scaffolds and buildings, in particular to a detachable connecting member between scaffolds and buildings. Background Art

[0002] The connecting member between scaffolds and buildings is a member that connects the scaffold frame to the main structure of the building and can transmit tensile and compressive forces. The wall-attached connection achieved by using the connecting member between scaffolds and buildings plays a very important role in strengthening the overall stability of the scaffold, improving its stable load-bearing capacity, and avoiding major accidents such as tipping or collapse.

[0003] Since the conventional structure of the connecting member between scaffolds and buildings needs to be embedded through the concrete exterior wall, if the post-embedding hole is not properly sealed in the later stage, it is easy to cause the problem of exterior wall leakage, increasing the difficulty of later return visits and maintenance and reducing work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a detachable connecting member between scaffolds and buildings is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The detachable connecting member between scaffolds and buildings includes a scaffold pipe, a pre-embedded threaded cylinder fixedly embedded in the exterior wall, and a steel plate attached to the exterior wall. A screw rod is threadedly connected to the pre-embedded threaded cylinder, and a nut is threadedly connected to the screw rod;

[0007] A through hole is formed in the steel plate, and the screw rod passes through the through hole. The nut forms a fastening fit with the surface of the steel plate, and one side of the steel plate is connected to the scaffold pipe through a telescopic rod structure.

[0008] As a preferred technical scheme of the utility model, the telescopic rod structure includes a hollow rod welded to the side wall of the steel plate, a movable rod slidably connected in the hollow rod, a butterfly screw threadedly connected to one end of the hollow rod, and a quick-release connector provided at one end of the movable rod.

[0009] As a preferred technical scheme of the utility model, the surface of the movable rod is provided with locking grooves distributed at equal intervals, and the butterfly screw is threadedly connected to one of the locking grooves.

[0010] As a preferred technical scheme of the utility model, the quick-release connector includes a chute formed in the movable rod, a bidirectional screw rotatably installed in the chute, two centering sliders symmetrically screwed on two opposite threaded ends of the bidirectional screw, and two arc-shaped positioning clips symmetrically fixed on the outer walls of the tops of the two centering sliders.

[0011] As a preferred technical scheme of the utility model, an anti-slip rotating cap is fixedly connected to the outer wall of one end of the bidirectional screw, and the outer walls of the two centering sliders are both slidably connected to the inner wall of the chute.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model pre-buries pre-buried threaded cylinders in the exterior wall. After the formwork of the structural beam is removed, it is connected to the customized scaffolding pipes. When the exterior scaffolding is removed, the screw rods can be taken out and reused, breaking the traditional method of using steel pipe connecting wall members, and avoiding disadvantages such as a large number of potential leakage problems on the exterior wall, difficult return visit and maintenance work, and low work efficiency.

[0014] 2. Through the telescopic rod structure provided, the quick-release connector on it can be quickly and firmly connected to the scaffolding pipe, and subsequent disassembly is also relatively convenient. At the same time, the telescopic rod structure has the function of telescopic adjustment, and can better adapt to the connection requirements under different conditions.
