Facing layer firmly combined and integrated modular exterior wall board and manufacturing method thereof

Abstract

The invention provides a facing layer firmly combined and integrated modular exterior wall board and a manufacturing method thereof. By adopting an integrated forming structure and forming method of acomposite steel wire net, a connecting bar, a reinforcing bar and an F-type structural part, boards have the advantages that a facing layer is firmly combined and not prone to falling off, a complexstructural connecting part is not used, a bonding layer is not contained, impact resistance strength is high, the forming process is easy, manufacturing efficiency is high, the connecting strength ofthe adjacent boards is high, a combination part is not prone to cracking, the upper end and the lower end of the boards are firmly connected with a floor frame, and construction contamination can be effectively controlled; and the boards are used for constructing a building exterior wall.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an integrated modular exterior wall panel with a firm combination of facing layers and a manufacturing method thereof. The modular panel is used for building exterior walls. Background technique [0002] In recent years, due to the advantages of fast construction speed and less pollution, prefabricated buildings have achieved considerable development. For the wall panels used in prefabricated buildings, there are still the following problems. [0003] 1. A typical modular wall panel is usually composed of several layers of functional layers through connectors and adhesive layers. These functional layers, especially the inner and outer side layers used as decorative surfaces, are not firmly combined with the main body of the panel and are easily fall off; and the adhesive layer contains harmful organic substances such as formaldehyde, which is harmful to the human bod...

AI Technical Summary

Problems solved by technology

[0003] 1. A typical modular wall panel is usually composed of several layers of functional layers through connectors and adhesive layers. These functional layers, especially the inner and outer side layers used as decorative surfaces, are not firmly combined with the main body of the panel and are easily Falling off; and the adhesive layer contains harmful organic substances such as formaldehyde, which is harmful to the human body and is not environmentally friendly

[0004] 2. The structure of the connecting piece that realizes the combination between the functional layers is complex, and it needs to be formed by special supporting equipment, and the installation operation of the connecting piece is complicated, and the cost of use is high

[0005] 3. The main structure of the plate is all composed of brittle materials, the toughness of the plate is poor, and the impact strength is low

[0006] 4. Partial combination is used in the manufacture of plates, the forming process is complicated and the manufacturing efficiency is low

[0007] 5. Since the board is formed by connecting parts and parts, its dimensional accuracy is low, which is not conducive to ensuring the thermal insulation, sound insulation and sealing performance of the building

[0008] 6. When assembled into a wall, the connection between adjacent plates (left and right ends) is not firm and easy to crack, which affects the beauty and safety of the wall

[0009] 7. The connection between the upper and lower ends of the board and the floor frame is not firm, and there are potential safety hazards for the wall board to collapse and fall
