Fastener for scaffold wall-connecting rod and use method thereof

Abstract

The invention discloses a fastener for a scaffold wall-connecting rod and a use method thereof. The fastener comprises a semicircular tubular long buckle cover and two semicircular tubular short buckle covers located on the long buckle cover in parallel, wherein the short and long buckle covers are buckled with each other to form a cylinder space for hooping a wall-connecting rod; a lateral wall connecting sheet extends from one end of the long buckle cover on one side of the outer wall of the long buckle cover along the direction vertical to the axis; a top wall connecting sheet extends from the other end of the long buckle cover along the axial direction; bolt holes are formed in the lateral wall connecting sheet and the top wall connecting sheet. According to the fastener provided by the invention, the scaffold wall-connecting rod and the main structure can be stably connected with each other; the use safety of the scaffold can be ensured; the two mounting modes of lateral wall and top wall can be selected according to the architectural characteristics of the structures; the fastener provided by the invention almost has no influence on the later secondary structure and decoration construction, is free from repairing processes, including reserved hole treatment, is capable of effectively shortening the construction period, can eliminate the water leakage hidden danger, can be turned over and reused and is strong in practicability.

Description

technical field [0001] The invention relates to a fastener for fixing scaffold connecting wall rods and a method for using the fastener, belonging to the technical field of scaffolding facilities. Background technique [0002] Scaffolding is a platform and protective facility for building high-altitude operations, and every project construction is inseparable from scaffolding. During construction, the scaffolding is fixed to the main structure through connecting wall rods, and the connecting wall rods are usually arranged in two steps and three spans. The fixing method between the wall rod and the main structure should also be reasonably selected according to the type of the structure, such as pre-embedded short steel pipes, pre-embedded casings, etc. [0003] When the fixed position structure of the connecting wall rod is a frame beam slab and the building is a masonry wall, such as figure 1 , the connecting wall rod 10 can be vertically intersected with the short steel p...

AI Technical Summary

Problems solved by technology

It can be seen that this approach mainly has the following four disadvantages: first, delaying the construction period

The opening treatment involves multiple processes such as opening sealing, plastering, waterproofing and decorative surface layer. The removal of scaffolding needs to wait for the opening treatment to be completed before proceeding down, which greatly delays the construction period

Second, material waste

This method requires pre-embedded short steel pipes 41. When the wall rod 10 is removed, the pre-embedded short steel pipe 41 needs to be cut off. In practice, the wall rod 10 is also cut off, and the pre-embedded short steel pipe 41 and the right-angle fastener 50 are not taken out. There is a serious material waste problem

Third, the hidden danger of water leakage

Because the large-scale project has been completed before the scaffolding 20 is dismantled, when the scaffolding 20 is dismantled, the progress is usually very fast. If the workers are not properly supervised during operation, leakage is very likely to occur at the opening

Fourth, affect the perception of architecture

It can be seen that this approach mainly has the following three disadvantages: first, the delay in the construction period

The demolition and reinforcement of the connecting wall rod 10 and the installation of doors and windows have multiple influences and constraints

When installing door and window frames, it is necessary to change the connecting wall rod 10. The installation of glass and the removal of scaffolding 20 are mutually restrictive, which makes coordination and management difficult and affects the construction period.

Second, material waste

This method requires pre-embedded steel pipes 41 before the installation of doors and windows 202, and requires long steel pipes 42 and jacking 43 for secondary modification, resulting in waste of materials

Third, there are security risks

It can be seen that this method mainly has the following two disadvantages: first, the internal and external reinforcement of the shear wall 60 is relatively complicated, and both fasteners 70 are required, and the shear wall 60 needs to be embedded in the casing (not shown in the figure), and the process is complicated , the material used is more

Second, there is a hidden danger of leakage

The pre-embedded casing needs to penetrate the shear wall 60, and there is a hidden danger of water leakage in the plugging of the casing
