Description

Can dismantle fastening type even wall spare

Technical Field

The utility model relates to a connecting piece field especially relates to a can dismantle fastening type and link wall spare.

Background

With the development of building construction technology, the requirements for protecting finished structural members are higher and higher, and the damage to the original building in the construction process is reduced as much as possible. The fastener type steel pipe scaffold, the disc buckle type steel pipe frame, the wheel buckle type steel pipe scaffold, the bowl buckle type steel pipe scaffold and the like adopted in the construction process generally adopt a wall connecting piece form connected with a steel pipe embedded in a structure, and adopt embedded pieces and drive in wall connecting piece connecting forms such as expansion bolts and the like. Specifically, the traditional connecting methods of the wall connecting pieces mainly include the following methods:

1. and embedding the concrete structure steel pipe into the wall connecting piece. The method is common and is generally used for embedding the structural steel pipe at the opening of the outer wall shear wall. The advantages are that construction is convenient, even the wall spare material acquires conveniently, and the shortcoming is also comparatively obvious, and pre-buried steel pipe needs to be cut off when demolising, causes the material waste of steel pipe, and the difficult shutoff in steel pipe hole after cutting off can cause the leakage point of outer wall in future. Meanwhile, the height of the floor is not consistent with the step pitch modulus of the scaffold, so that the placement position of the wall connecting piece cannot be completely calculated according to the scheme.

2. Steel plate embedded parts are embedded in the concrete member and welded with the steel pipes to form a wall connecting part. The method is not common, and has the advantages that the embedded part embedding position can be constructed basically according to the theoretical calculation position, the tie point adopts welding, and the strength is high. The defects are that materials are wasted, the construction is complicated, and the steel plate position left after the steel pipe is cut off at the embedded part position is easily subjected to painting or coating construction to generate hollowing when the embedded part position is dismantled.

3. And an expansion bolt is driven into the structural part to connect the steel plate with the steel pipe to form a wall connecting piece. The method is mainly carried out later and is also more common. The advantage does for can doing after carrying out according to scaffold frame stride modulus, and the requirement is calculated to the satisfying scheme that can be better, and construction installation and dismantlement are all comparatively convenient simultaneously, but the material major part recycle. The expansion bolt has the disadvantages that the expansion bolt needs to be embedded after the outer wall is drilled, the hidden danger of structural damage and outer wall leakage is caused, and the cost of the expansion bolt is high.

Therefore, no matter how the method is, the original structural member is damaged to a certain extent, which causes the hidden danger of later repair and leakage.
