Description

Technical Field

[0001] This utility model relates to the field of building insulation materials technology, specifically to a prefabricated building composite insulation wall panel. Background Technology

[0002] Prefabricated composite insulated wall panels are a new type of building envelope material that integrates insulation and decoration. They are manufactured using factory prefabrication. These wall panels significantly reduce building energy consumption, meeting the requirements for green and energy-saving buildings. Simultaneously, their prefabricated construction method greatly reduces on-site wet work, improves construction efficiency, shortens the construction period, and effectively reduces environmental pollution and resource waste. They are a widely used and important component in modern industrialized building systems.

[0003] Currently available composite insulation wall panels are often made by combining extruded polystyrene (XPS) boards with lightweight aerated concrete (AAC) boards. While these panels achieve a certain level of thermal insulation, their thickness results in a large footprint during construction. Furthermore, their fire resistance rating is only Class B, making them unsuitable for buildings with higher fire safety requirements. Therefore, a prefabricated composite insulation wall panel is needed to address these issues. Utility Model Content

Anchor bolts are installed at the corners of the vacuum insulation composite insulation board. The anchor bolts pass through the vacuum insulation composite insulation board and are connected to the ALC wall panel to provide reinforcement.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1-5 The present invention provides the following technical solution:

[0023] Example 1

[0024] A prefabricated building composite insulation wall panel includes an ALC wall panel 1 and a vacuum insulation composite insulation board 2, wherein several vacuum insulation composite insulation boards 2 are laid flat on one end face of the ALC wall panel 1; as shown Figure 1 As shown, this is a diagram of the arrangement of vacuum thermal insulation composite insulation board 2 on ALC wall panel 1. The size of ALC wall panel 1 is 900*3000mm, the size of the larger vacuum thermal insulation composite insulation board 2 is 400*600mm, and the size of the smaller vacuum thermal insulation composite insulation board 2 is 300*400mm.

[0025] The vacuum insulation composite insulation board 2 includes a vacuum insulation board 21 and a protective covering layer 22. The protective covering layer 22 is formed by completely wrapping and curing the vacuum insulation board 21 with a covering slurry. The protective covering layer 22 is made of a fire-resistant material with a fire rating of Class A, specifically composed of flame-retardant expandable polystyrene foam particles, hydraulic inorganic cementitious materials, polymers, additives, etc. The protective covering layer 22 protects the vacuum insulation board 21, preventing the membrane bag on its surface from being punctured and damaged, and at the same time improving the fire resistance of the composite insulation wall panel.

[0026] The protective layer 22 is provided with an alkali-resistant glass fiber mesh 23 inside. The alkali-resistant glass fiber mesh 23 is located on both sides of the vacuum insulation board 21 and is arranged parallel to the vacuum insulation board 21. The alkali-resistant glass fiber mesh 23 can improve the strength and flexural strength of the protective layer 22.

[0027] A bonding layer 3 is formed between the vacuum insulation composite insulation board 2 and the ALC wall panel 1 by adhesive. The adhesive used in the bonding layer (3) is adhesive mortar. Anchor bolts 4 are installed at the corners of the vacuum insulation composite insulation board 2. The anchor bolts 4 pass through the vacuum insulation composite insulation board 2 and connect to the ALC wall panel 1 to provide reinforcement. The number of anchor bolts 4 is not less than 6 per m. 2 The vacuum thermal insulation composite insulation board 2 is bonded to the ALC wall panel 1 using a combination of adhesive mortar bonding and anchor bolt 4 fixing, and the number of anchor bolts 4 used is no less than 6 per m. 2 This can effectively improve the composite strength of the building's composite insulation wall panel. Compared with traditional extruded polystyrene insulation materials, vacuum insulation composite insulation board 2 is thinner, has higher compressive strength, lower thermal conductivity, and Class A fire resistance, which can effectively improve the overall performance of the building's composite insulation wall panel.

[0028] Example 2

[0029] All other features are the same as in Example 1. The only difference between Example 2 and Example 1 is the size of the composite insulation wall panel and the arrangement of the vacuum insulation composite insulation board 2 on the ALC wall panel 1. Figure 5As shown, in Example 2, the size of ALC wall panel 1 is 600*3000mm, the size of the larger vacuum insulation composite insulation board 2 is 400*600mm, and the size of the smaller vacuum insulation composite insulation board 2 is 300*400mm.

[0030] The above two sizes of composite insulation wall panels are the two commonly used sizes in actual use. The specific size can be adjusted according to the building needs. At the same time, the arrangement of the vacuum insulation composite insulation board 2 on the ALC wall panel 1 can be adjusted so that the composite insulation wall panel can achieve the corresponding size and insulation performance.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
