Light concrete partition wall construction structure of assembled steel structure building and method thereof Technical Field The invention relates to the technical field of assembled buildings, in particular to an assembled steel structure building lightweight concrete partition wall construction structure and a method thereof. Background Along with the continuous promotion of the large-scale popularization and the industrial construction standard of the assembled steel structure building, the non-bearing partition wall is used as a key component of a building enclosure system, and the connection reliability, the construction efficiency, the crack resistance and hollowing resistance and the light weight level of the non-bearing partition wall directly determine the overall quality and the construction efficiency of the building. In the current assembly type steel structure building partition construction, traditional brickwork wall body, ALC light partition board are mainstream application form, and conventional cast-in-situ lightweight concrete partition also has a small amount of use, but three types of wall bodies all have outstanding technical short slab, can't adapt to industrialization, the rapidness of assembly type steel structure building, high-quality construction demand: 1. The traditional masonry wall has the advantages of large dead weight, great increase of the main body load of the steel structure, violation of the lightweight design principle of the building, heavy site wet operation, complicated masonry procedures, long construction period, conflict with the efficient construction concept of the assembled building, and potential safety hazards such as cracking of the wall, separation and falling off of the main body structure and the like easily caused by the fact that the masonry is simply connected with the steel column and the steel beam only through tie bars, and extremely poor integrity. The ALC light partition board has the advantages of light weight, high installation speed, large number of board splicing seams, easy cracking of the splicing seams under the stress action, water seepage and sound insulation performance attenuation, insufficient anchoring reliability of joints with a steel structure main body, easy loosening of connecting pieces, easy board displacement and deformation after long-term use, poor board field cutting suitability, high complex house type construction difficulty and limited overall impact resistance and deformation resistance. 3.

To sum up, current brickwork wall body, ALC wall body and traditional lightweight concrete partition wall can't all satisfy the core demand that assembled steel construction building connection is reliable, the formwork is firm, pour closely knit, the high-efficient, anti crack of construction anti hollowing simultaneously.
