Compared with the traditional building mode, most building components of the assembled building are produced and processed in workshops; the assembly operation is carried out on the construction site, so that the assembly operation is rapid and convenient; adopting building and decoration integrated design and construction; design standardization and management informatization; meets the requirements of green buildings in China. The assembled building is beneficial to improving the construction quality, accelerating the engineering progress, adjusting the supply relation, improving the construction quality, civilized construction, safety management, environmental protection and saving resources. Among them, the fabricated shear wall structure is the most widely used and fastest growing fabricated concrete structure technology in China in recent years. The assembled concrete shear wall structure is a concrete shear wall structure which is formed by completely or partially adopting prefabricated wallboard components and post-pouring concrete and cement-based grouting materials in a reliable connection mode.
The assembled heat insulating sandwich concrete composite shear wall is a composite wall body integrating structure and heat insulation. The main structure of the reinforced concrete slab comprises an inner reinforced concrete slab and an outer reinforced concrete slab and a sandwich insulation board. The wall body meets the requirements of building structure and heat preservation integration. Under the requirements of energy conservation and environmental protection, the assembled heat-preservation sandwich concrete composite shear wall can effectively shorten the construction period, save the fund cost, improve the durability, fire resistance limit, heat transfer coefficient, economical efficiency, combustion grade and other performances of the outer wall structure of the building, solve the problems that the traditional outer surface thin-plastering outer wall heat preservation system commonly has hidden dangers such as easy crack generation, leakage, hollowing, falling off, main structure construction and outer wall heat preservation system construction respectively, lead to long construction period, shorter service life than the structural life, difficult later maintenance and the like. Meanwhile, the assembled heat-insulating sandwich concrete composite shear wall can also be constructed together through the heat-insulating system and the main building system, so that the outer wall heat-insulating system serving as a hidden project can monitor and control a series of problems including thickness, quality, energy-saving indexes and the like of a heat-insulating layer in the construction process, thereby preventing potential quality hazards caused by human factors and fundamentally controlling the heat-insulating performance of the outer wall of the building. Has important significance for promoting energy conservation and emission reduction of buildings and realizing 'carbon neutralization' targets.

step five: placing the prefabricated assembled composite wallboard (1) in the second step in a concave groove, placing a reinforcement cage at the lower part of the prefabricated L-shaped constructional column (5) in the third step in an L-shaped groove (9), and fixedly connecting the assembled composite wallboard (1) with a foundation beam (2) after adjusting the positions of the assembled composite wallboard (1) and the L-shaped constructional column (5);
step six: the formwork is used for pouring the connection position of the L-shaped constructional column (5) and the independent foundation (3), namely pouring concrete into the pouring L-shaped groove (9) and curing, so that the L-shaped constructional column (5) and the independent foundation (3) are connected into a whole;
step seven: and after the concrete at the connection position of the L-shaped constructional column (5) and the independent foundation (3) reaches the curing target, installing a layer of wall.
