Description
Technical Field
The invention relates to the technical field of building construction, in particular to an assembled bolt connection scaffold wall connecting piece and an installation method.
Background
In the construction process of cast-in-place concrete structures and prefabricated buildings in constructional engineering, a scaffold needs to be erected outside a vertical wall structure, and the erected scaffold needs to be connected with a building structure. The conventional scaffold connecting modes mainly include the following modes:
1. stay-supported combination
The bracing and combining method is generally used for erecting a bottom layer with the height less than 24m and a multi-storey building on a scaffold, using embedded steel bars and the scaffold to brace a main body structure, or using fasteners to connect horizontal steel pipes and the scaffold into a whole after the embedded steel bars and short steel pipes are welded.
The bracing combination cost is lower, and need not brickwork mend the hole, so use more in the multilayer building. But the defects are that the connecting steel pipe needs to be welded with the embedded steel bar, the process is complicated, the welding quality is difficult to guarantee, and the welding has potential safety hazards.
2. Pre-buried steel pipe
The embedded steel pipe is the most common wall connecting piece method at present, and can play a role in rigid connection. The embedded steel pipes are embedded in the beam by about 20cm through the vertical short steel pipes before concrete pouring, and are exposed by about 20cm through the beam back, and after the concrete pouring is finished, the vertical rods and the vertical short steel pipes are connected through the horizontal long steel pipes.
Its advantages are high rigidity and accurate position. The method has the disadvantages of high cost and troublesome disassembly, and holes of the holes left in the masonry are repaired. Compared with other methods, the method for embedding the steel pipes has the advantages that the number of the used steel pipes and fasteners is large, and therefore the cost is high. Meanwhile, the method needs to leave a hole on the wall, plugging needs to be carried out after construction is finished, if plugging is not tight, water prevention of the outer wall is hidden, and attention needs to be paid to the southeast coastal area and the rainy area.
3. Rear anchorage
This is improved against the shortage of the pre-buried steel pipe. During construction, holes are drilled in the side faces of the beams, expansion anchor bolts or chemical anchor bolts are installed, and then the beams are connected through anchor plates which are welded with steel pipes into a whole in advance.
The method has the advantages of good rigidity, no hole repairing process and no hidden danger of water seepage. However, the construction is very complicated, especially the drilling. Usually 2 expansion anchors are used, which have a low load-bearing capacity and are also easily loosened and cannot withstand repeated loads. After the construction is finished, the anchor bolt is scrapped and cannot be reused, so the cost is high.
4. Hoop fastening method
Pre-buried in different major structure, after the post template is demolishd, hooped the concrete column with four short steel pipes and four fasteners, then connected through a long steel pipe and stand.
Its advantages are high rigidity and convenient construction. The method has the disadvantages that the used materials are very many, three fasteners and four short steel pipes are added compared with a method of pre-embedding the steel pipes, and the economy is very poor for a high-rise building with a long construction period. And the hole is also needed to be repaired on the wall body, and the waterproof aspect is also poor.
Therefore, there is a need for a scaffolding wall element and method of installation that avoids the aforementioned drawbacks.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information is prior art that is known to a person skilled in the art.
