Description

Technical Field

[0001] The invention relates to the technical field of building engineering, in particular to a prefabricated lightweight lattice concrete wall assembly structure system. Background Art

[0002] Prefabricated concrete structure is the main structural form of modern building industrialization. Prefabricated concrete is a concrete component that is assembled and connected with prefabricated components as the main load-bearing components. The main feature of prefabricated buildings is that the components are prefabricated in the factory, then transported to the site and installed by machinery or manual labor.

[0003] Prefabricated concrete structures have the characteristics of high quality assurance rate, good appearance, fast construction speed, short construction period and low cost.

[0004] In multi-story buildings, the use of ordinary full concrete wall assembly is heavy and wasteful, which is not conducive to industrial production and brings inconvenience to the transportation of components. Lattice assembly wall solves the above problems and has many advantages, such as good thermal insulation performance, uniform force distribution, material saving, sound insulation and heat insulation, and fast construction speed.

[0005] The current lattice assembly wall is a load-bearing wall composed of concrete as the lattice frame and lightweight materials. This wall integrates earthquake resistance, load bearing, light weight, energy saving, heat preservation, heat insulation, fire resistance, sound insulation, and environmental protection, and has the characteristics of low comprehensive cost, convenient and fast construction.

[0006] The common shortcomings of the current lattice wall are: the structural force is not clear, the connection of the wall column is difficult, and the lattice column and lattice beam are mostly connected by cast-in-place, resulting in low assembly rate and low prefabrication rate. For example, when the connection of lattice column and lattice beam is prefabricated as a whole, steel sleeve connection is used, which is costly and the cross-section of the lattice beam column is small, which does not meet the assembly requirements. Summary of the invention

[0007] Purpose of the invention:
