Description

Technical Field

[0001] The invention relates to the technical field of house construction, in particular to a constrained autoclaved aerated concrete sandwich wallboard load-bearing house structure system. Background Art

[0002] The constrained autoclaved aerated concrete sandwich wallboard load-bearing house structure system is a new type of structural system. Its main feature is that aerated concrete sandwich wallboard is used as a load-bearing component. This wallboard has a sandwich layer in the middle, which can play a role in heat preservation. In terms of structure, through reasonable connection structure and constraint measures, the wallboard can ensure the stability of the structure when it bears vertical loads (such as house self-weight, residential load, etc.) and horizontal loads (such as wind loads and earthquake effects). In terms of earthquake resistance, constraint components (such as structural columns, ring beams, etc.) are used to cooperate with aerated concrete sandwich wallboards. Structural columns can enhance the integrity and vertical bearing capacity of the wall, and ring beams can constrain the deformation of the wall in the horizontal direction and improve the earthquake resistance of the house. The design of its connection nodes is the key part. It is necessary to ensure reliable connection between the wallboard and other components (foundation, beams, columns, etc.) so that the force can be effectively transmitted.

[0003] For low- and medium-rise buildings, such as new rural houses, which are mostly two- or three-story building structures, traditional construction methods are mostly reinforced concrete frames combined with bricklaying construction. It is necessary to cast not only the steel skeleton of the house but also the main load-bearing walls. The construction is difficult and the construction period is long. The amount of concrete required is large, and the construction cost is high. In addition, the narrow rural roads make it difficult for large concrete equipment to enter, which greatly increases the construction difficulty. For this reason, a constrained autoclaved aerated concrete sandwich wall panel load-bearing house structure system is proposed. Summary of the invention
