Technical Field

[0001] The present invention belongs to the technical field of prefabricated buildings and relates to a prefabricated thermal insulation wall panel, specifically a prefabricated thermal insulation wall panel connected by anchor bonding and a construction method thereof. Background Art

[0002] With the development of building industrialization, prefabricated buildings are increasingly being used. With their advantages of rapid construction, controlled quality, environmental protection, and energy conservation, they have gradually become a key development direction in the construction industry. When prefabricated buildings are used in extremely cold regions, prefabricated insulated wall panels are a key component of the building. The insulation layer is composed of several insulation boards, and there are various methods for attaching the insulation layer to the wall panels. Common methods include bonding, where the insulation layer is directly adhered to the wall panels using adhesives, and mechanical fastening, where bolts and other mechanical components are used. However, traditional connection methods can lead to many problems in the actual application of prefabricated insulation wall panels. For example, it is difficult to accurately position the insulation board when using the bonding method, the construction process is complicated, high labor skills are required, and it is inconvenient to disassemble and maintain, which reduces the industrialization and efficiency of the building. When using the mechanical fixing method, the bolts have poor durability and are prone to thermal bridge effects, which have an adverse effect on the mechanical properties and thermal insulation properties of the insulation wall panels. Summary of the Invention In view of this, the present invention aims to propose an assembled thermal insulation wall panel and its construction method using anchor bonding connection, so as to solve the problems of the existing assembled thermal insulation wall panels, such as the difficulty in accurately positioning the insulation panels and the inconvenience in disassembly and maintenance when the bonding method is used, and the poor durability of the bolts and the easy occurrence of thermal bridge effects when the mechanical fixing method is used, avoid the hidden dangers of decreased mechanical properties and thermal insulation performance of the thermal insulation wall panels, reduce construction difficulty, and improve the industrialization and efficiency of buildings.

[0003] To achieve the above-mentioned object, the present invention adopts the following technical solution: an assembled thermal insulation wall panel using anchor bonding, comprising a thermal insulation layer, a concrete wall panel and an adhesive, wherein the thermal insulation layer and the concrete wall panel are connected by the adhesive; The insulation layer is formed by splicing a number of autoclaved aerated concrete insulation boards. Each autoclaved aerated concrete insulation board is pre-embedded with insulation layer embedded parts. A number of wall panel embedded parts are pre-embedded on the concrete wall panels. The insulation layer embedded parts are connected to the wall panel embedded parts by bolts.

[0007] Furthermore, a plurality of embedded plates are arranged around the wall panel embedded part, a circular hole is opened in the center, and bolts pass through the circular hole and the through screw holes of the insulation layer embedded part in sequence to anchor the insulation layer embedded part to the wall panel embedded part.

[0008] Furthermore, a plurality of reserved circular holes are reserved on the concrete wall panel, and the size and position correspond to the central circular holes of the wall panel embedded parts, and a plurality of grooves are reserved on the outside, and the size and position correspond to the anchoring protrusions of the insulation layer embedded parts.

The insulation layer embedded parts extend from the center of the anchoring protrusion into the autoclaved aerated concrete insulation board; Step 2: Pour concrete at the construction site to obtain a concrete wall panel with built-in wall panel embedded parts. During pouring, a reserved circular hole for a commonly used hexagonal wrench is reserved on the inner side of the concrete wall panel at the wall panel embedded parts, and a groove corresponding to the size of the anchoring protrusion is reserved on the outer side; Step 3: After the concrete wall panels are cured, install the insulation layer; Step 4: Use foam glue to fill the joint gaps between the autoclaved aerated concrete insulation panels and the circular holes inside the concrete wall panels. After complete curing, a reliable anchoring connection between the concrete wall panels and the insulation layer is achieved.

[0011] Furthermore, in step 3, the method for installing the insulation layer is: install several autoclaved aerated concrete insulation boards in sequence from the bottom side of the concrete wall panel to the top side, first clean the outer base of the concrete wall panel and evenly apply the adhesive, then embed the anchoring protrusion of the autoclaved aerated concrete insulation board into the outer groove of the concrete wall panel, and then pass the bolt through the inner circular hole of the concrete wall panel and the center circular hole of the wall panel embedded part and screw it into the embedded part of the insulation layer, and then splice the next autoclaved aerated concrete insulation board through the splicing grooves and splicing protrusions around the board, and repeat the operation until all the autoclaved aerated concrete insulation boards are installed.
