Prefabricated wall high-strength concrete connecting joint and construction method

Abstract

The invention relates to a prefabricated wall high-strength concrete connecting joint and a construction method. The connecting joint comprises at least two prefabricated wall bodies, wherein each prefabricated wall body comprises a high-strength concrete wall body, a wall top embedded part is pre-embedded in the top of each high-strength concrete wall body, a connecting box and a wall bottom embedded part are pre-embedded in the bottom of each high-strength concrete wall body, the wall top embedded part is provided with an elevation adjusting part matched with each wall bottom embedded part, the adjacent prefabricated wall bodies are connected through a connecting part, and the connecting boxes are filled with high-strength grouting materials used for connecting the adjacent prefabricated wall bodies into a whole. Compared with the prior art, the method has the advantages of simplicity and high efficiency in construction, visual quality inspection and the like.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a high-strength concrete connection node of a prefabricated wall and a construction method. Background technique [0002] Prefabricated buildings refer to buildings in which the main parts of the structural system, external protection system, equipment and pipeline system, and interior system are integrated with prefabricated parts. In prefabricated concrete buildings, some or all components of the structural system are produced in the component prefabrication factory, and then transported to the construction site through corresponding transportation methods, and the components are assembled through reliable connection technology by using reliable installation methods and installation machines. The architecture of buildings that use function. [0003] Between the prefabricated components and the joints between the prefabricated components and the cast-in-place an...

Problems solved by technology

[0006] The quality of grouting has a crucial influence on the actual bearing capacity of the steel sleeve grouting connection joints. The manufacturing accuracy of the components and the construction technology level of the on-site personnel will affect the grouting compactness. truncated or misplaced

The main reasons are: there are foreign objects in the sleeve, which leads to difficulty in grouting; irregular grouting operations lead to grout leakage and defects; the accuracy of components or installation accuracy is poor, and the steel bars are cut and shortened when they are forced into place

Once a construction defect occurs, it is very difficult to repair
