Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation walls, in particular to a prefabricated building thermal insulation wall. Background Technique

[0002] A prefabricated building refers to a building in which a large amount of on-site operation work in the traditional construction method is transferred to a factory. Building components and fittings are processed and manufactured in the factory and transported to the building construction site, and then assembled and installed on-site through reliable connection methods; there are many types of walls, including single-material walls and composite-material walls. Considering factors such as enclosure, load-bearing, energy conservation, and aesthetics, designing a reasonable wall scheme is an important task in building construction. The prefabricated wall is also called a prefabricated wall that can be supported and installed by being leaned against. However, the existing structure of the prefabricated wall that can be supported and installed by being leaned against is relatively simple, with poor load-bearing effect. At the same time, it is troublesome to route wires in the wall, and the practicability is relatively poor.

[0003] A Chinese patent with the publication number CN207846772U in the prior art discloses a prefabricated wall that can be supported and installed by being leaned against. The technical key points are as follows: including a prefabricated wall body, etc. It can be seen from several figures in the specification of this technical solution that the structure of the wall itself in this technical solution is relatively simple and no thermal insulation treatment is done. When in use, the thermal insulation effect of the wall itself is relatively poor. Especially in winter and summer, more energy is required for indoor thermal insulation treatment, resulting in relatively poor use effect. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a prefabricated building thermal insulation wall, which solves the problem that the thermal insulation effect of the wall itself in the prior art is relatively poor. Especially in winter and summer, more energy is required for indoor thermal insulation treatment, resulting in relatively poor use effect.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme:

Multiple layers of thermal insulation boards are sleeved on the multiple connecting screws. Through holes for matching the connecting screws are opened on the multiple layers of thermal insulation boards. An external pressing head for pressing the multiple layers of thermal insulation boards is threadedly connected to the connecting screws. Threaded holes are arranged at the corners of the multiple layers of thermal insulation boards. It also includes a four-corner pressing piece for pressing the four corners of four adjacent layers of thermal insulation boards. The four-corner pressing piece is fixed to the outside of the multiple layers of thermal insulation boards through bolts matching the threaded holes. Among them, the wall body can be a cast-in-place wall body or a precast wall body. With the structure of this application, the fixing plate can be embedded in the wall body, so as to facilitate the detachable connection of multiple layers of thermal insulation boards in the later stage, thereby improving the building thermal insulation effect. At the same time, the multiple layers of thermal insulation boards can be well fixed through the external pressing head. After the installation of adjacent multiple layers of thermal insulation boards, the adjacent corners of four adjacent layers of thermal insulation boards are pressed by the four-corner pressing piece to prevent deformation and affect the thermal insulation effect.

[0007] Furthermore, the four-corner pressing piece includes an inner piece and an outer piece. Four slot strip fixing grooves are opened on the inner piece. The outer piece is used to close the fixing grooves. An external screw is arranged on the inner piece. A nut for fixing the outer piece is threadedly connected to the external screw. A through hole for the bolt to pass through is opened on the outer piece. With this structure, the inner piece can be fixed to the multiple layers of thermal insulation boards by bolts first, then the slot strips between the gaps of adjacent thermal insulation boards can be installed, and then the outer piece can be fixed by matching the external screw and the nut, so as to realize the end fixing of the slot strips and prevent them from falling off. It is also possible to directly remove the outer piece in the later stage to replace the aging slot strips.

[0008] Furthermore, the multiple layers of thermal insulation boards include a thermal insulation layer, a heat insulation layer, a waterproof layer and a shell arranged in sequence from the inside to the outside. Stone-like paint is arranged on the outside of the shell. With this structure, good thermal insulation and waterproof effects can be achieved.

[0009] Furthermore, chamfers are arranged on the shell. With this structure, it is convenient to install the slot strips.

[0010] Furthermore, the connecting screw includes a screw base arranged on the fixing plate. A screw body is threadedly connected to the screw base. The external pressing head is threadedly connected to the screw body. With this structure, it can
