Assembled building wall

Technical Field

Background

With the development of modern industrial technology, building houses can be manufactured in batches and sets like machine production. Prefabricated house components are transported to a construction site to be assembled, and the assembled building is interesting in the beginning of the 20 th century and is realized in the end of the sixties. The first attempts made in English, French, Soviet Union, etc. The assembly type building has high construction speed and low production cost, and is rapidly popularized and developed all over the world. Early fabricated buildings were rather rigid and uniform in appearance. Later improvements in design have resulted in increased flexibility and versatility to allow modular construction not only in batch, but also in a wide variety of styles.

In a mixed structure house, the wall body bears the vertical pressure transmitted by the house (building) cover and the self weight of the house (building) and also bears the horizontal force caused by wind and earthquake. The masonry structure wall can generate cracks of different forms under the action of earthquake. The wall body parallel to the horizontal earthquake action direction is under the action of in-plane earthquake shear force, and under the combined action of the earthquake shear force and the vertical load, when the main tensile stress in the wall body exceeds the strength of the masonry, the wall body can generate an inclined crack or a crossed inclined crack. The masonry structure is an important reason for the earthquake damage because the connection among the walls, between the walls and the floor and between other parts of the structure is not firm. The cross-hatch is a typical shear fracture. Most of the existing wall structures are rigid, when the existing wall structures are excited by an earthquake, the shear-resistant bearing capacity of the wall is insufficient, and when the existing wall structures bear a large horizontal force, cracks can appear, so that the stability of the fabricated building becomes a problem which needs to be solved urgently in the building engineering.
