Description

Connection structure of prefabricated solid wall and prefabricated double-sided superposed wall Technical Field The invention relates to the technical field of prefabricated wall connection, in particular to a connection structure of a prefabricated solid wall and a prefabricated double-sided superposed wall. Background Prefabricated walls are a wall system in modern building industrialization, the components of which are produced in advance in professional factories or construction sites and then transported to construction sites for rapid assembly to form the outer walls, inner partition walls or bearing walls of the building. Compared with the traditional on-site masonry wall, the prefabricated wall has the core advantages that quality controllability ‌ and ‌ brought by ‌ industrial production is greatly shortened, the construction period ‌ is shortened, and environmental protection benefits brought by on-site wet operation are reduced by ‌. Prefabricated wall ‌ is classified according to functions and positions ‌ into ‌ inner wall boards and ‌ outer wall boards, and ‌ is classified according to structural materials and systems into ‌ prefabricated concrete wall boards, ‌ prefabricated shear walls, ‌ light prefabricated wall boards and ‌ other types ‌. ‌ A When the prefabricated wall is used for building a building, a solid wall is used as a bearing main body of the building, the double-sided laminated wall is often used as a main body frame structure of a heat preservation wall, a sound insulation wall and other materials are injected into the laminated wall in the building process, in the practical building process, the steel bars on the prefabricated wall are connected with the bundled steel bar cages, and concrete is poured outside the steel bar cages, so that the connecting effect between the multi-sided prefabricated wall can be ensured, but the prefabricated double-sided laminated wall is in a hollow state, the concrete is easy to pour first, the concrete enters the inside of the laminated wall, and finally, the situation that the heat preservation, the sound insulation and other materials are poor in effect after filling the inside of the laminated wall is influenced (if the materials such as heat preservation, sound insulation and the like are filled into the inside of the laminated wall first, a large amount of materials are easy to spread to a concrete filling area, and finally, the strength after concrete pouring is influenced). After the positioning and installation, the reserved dowel bars of the lower precast concrete wallboard are inserted into the hollow wall body of the upper precast concrete wallboard, and the two precast concrete wallboards are vertically connected in a post-cast concrete mode, so that the required post-cast concrete amount is small, the operation is simple, the construction efficiency is higher than that of a connection mode adopting a grouting sleeve, the work amount of the post-cast concrete is reduced compared with that of a double-sided superposed shear wall system, and the problems are reflected to a certain extent. Therefore, how to provide a connection structure between a prefabricated solid wall and a prefabricated double-sided composite wall is a problem to be solved by those skilled in the art. Disclosure of Invention The invention aims to provide a connecting structure of a prefabricated solid wall and a prefabricated double-sided laminated wall, which aims to solve the problem that the poor effect is finally influenced after filling of materials such as heat preservation, sound insulation and the like in the laminated wall due to the fact that the prefabricated double-sided laminated wall is in a hollow state and the concrete is easy to pour into the inside of the laminated wall by adopting a mode of connecting steel bars on the prefabricated wall with a bundled steel bar cage and pouring the concrete outside the steel bar cage. The connecting structure of the prefabricated solid wall and the prefabricated double-sided superposed wall is applied between a solid wall structure and a superposed wall structure, comprises pouring templates and isolation plates, wherein two pouring templates are arranged and are opposite to each other; The isolation plate is arranged between the two pouring templates; the laminated wall structure comprises a laminated wall back plate and a laminated wall panel, wherein a plurality of transverse and longitudinal staggered longitudinal steel bars and transverse steel bars which form a net structure are embedded in the laminated wall panel and the laminated wall back plate, traction steel bars are embedded between the laminated wall panel and the laminated wall back plate, and a plurality of first movable notches are formed in the isolation plate; a plurality of locking assemblies are arranged between the two pouring templates, each locking assembly comprises a traction bar, limiting notches are formed in the two ends of each tra
