Description

Technical Field

[0001] The present application relates to the technical field of prefabricated wall construction, and in particular to a prefabricated slat wall and structural beam offset connection device and a construction method. Background Art

[0002] With the continuous improvement of my country's social and economic level, the construction industry has achieved unprecedented development. Since the construction industry has a serious problem of resource waste during construction, prefabricated buildings can not only reduce construction pollution, but also improve production efficiency and ensure the quality and safety level of buildings. Prefabricated buildings save some manpower, material and financial resources. In addition, compared with on-site concrete and masonry, prefabricated buildings adopt factory mechanisms, process through the means of standardized factory modules, and transport to the site for direct assembly, which greatly saves construction time and responds to the country's call for green environmental protection. For the non-load-bearing walls inside the building - filling walls, they have gradually tended to be assembled in recent years. ALC strip wall is a new material with superior performance. It is mainly made of lime, cement, and fine ash captured after coal combustion as raw materials, and then made into porous concrete panels after high-pressure steam curing.

[0003] ALC strip walls are set at different positions according to design requirements. Some strip walls are placed under the structural floor slabs, and some strip walls are placed under the structural beams.

[0004] However, due to the requirements of the building space layout size, there will inevitably be a situation where some of the slat walls and structural beams are offset. The offset makes it difficult for the slat walls and structural beams to form an effective connection, which in turn leads to poor stability in the wall connection. Summary of the invention
