Description

Technical Field

[0001] This utility model relates to the field of building insulation materials technology, specifically to a novel low-carbon integrated building insulation panel. Background Technology

[0002] With the continuous improvement of building energy efficiency standards, the performance requirements for thermal insulation materials are becoming increasingly stringent. Traditional building insulation systems have many problems, such as the risk of insulation cracks, detachment, and hollowing; the risk of thermal bridging caused by embedded parts and fasteners in exterior wall decoration; complex and cumbersome construction; fire hazards; and large space occupation. These problems not only affect the insulation effect and service life of buildings, but also pose a threat to building safety.

[0003] Therefore, it is of great significance to develop a high-performance, environmentally friendly, low-carbon building insulation integrated panel that meets fire resistance Class A requirements and is easy to construct. Summary of the Invention

[0004] This utility model aims to solve the problems of poor insulation effect, poor durability, complex construction, high fire hazard and insufficient environmental protection of existing building insulation systems, and provides a new type of low-carbon building insulation integrated panel.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel low-carbon building insulation integrated panel includes two layers of wire mesh, with an organic insulation board layer and two inorganic insulation layers positioned between them. The organic insulation board layer is located between the two inorganic insulation layers. Steel wire forks are diagonally inserted into both the inorganic and organic insulation layers, and these forks are welded to the wire mesh to form a three-dimensional wire mesh frame. Waterproof cement mortar is applied to the outer wire mesh. The inorganic and organic insulation layers are physically bonded together through thermal break tie rods and the penetration of the steel wire forks, forming an integral mesh frame. This, along with the waterproof cement mortar, forms the outer protective layer of the product. The inorganic insulation layer is selected to be 30mm thick, and after bonding with the waterproof cement mortar, the structure on both sides of the organic insulation board layer is greater than 50mm.

[0007] The steel wire mesh uses high-strength galvanized steel wire with a diameter of 0.8-1.2mm and a mesh size of 150mm. The organic insulation board layer uses graphite polystyrene board with a thickness of not less than 100mm. The inorganic insulation layer uses inorganic vitrified microsphere board with a density of 60kg / m³. 3 The thickness is 30mm. The steel wire fork is made of galvanized iron wire with a diameter of 0.5-1.0mm, and the penetration rate through the organic insulation board layer is 30%-50%; the thickness of the waterproof cement mortar is 20mm.

[0008] This utility model provides a method for preparing a novel low-carbon building insulation integrated panel, comprising the following steps:

[0009] ① Material preparation: Select steel wire mesh, organic insulation board layer, inorganic insulation layer, steel wire fork, thermal break tie rod, and waterproof cement mortar according to the above requirements;

[0010] ②Structural Assembly: Place two layers of wire mesh in parallel, and place an organic insulation board layer and an inorganic insulation layer between the two layers of wire mesh, so that the organic insulation board layer is positioned corresponding to the inorganic insulation layer and the main structural walls, beams, and columns; then, insert the wire forks diagonally into the inorganic insulation layer and the organic insulation board layer, and weld the wire forks to the wire mesh to form a three-dimensional wire mesh frame; the thermal break tie rods penetrate through the inorganic insulation layer and the organic insulation board layer;

[0011] ③ Surface treatment: Cement mortar is sprayed onto the outer wire mesh to form waterproof cement mortar, with a spray thickness of 20mm;

[0012] ④ Curing and molding: The assembled integrated insulation panel is cured at a temperature of 20-30℃ for 24-48 hours.

[0013] The beneficial effects of this utility model are:

[0014] 1. Excellent thermal insulation performance: The combination of organic and inorganic insulation layers effectively improves the thermal insulation performance of the integrated insulation panel, reduces building energy consumption, and achieves low-carbon goals. Tests show its thermal conductivity can be as low as 0.03-0.05 W / (m²). · K), compared with traditional insulation materials, the energy-saving effect is significantly improved.

[0015] 2. Excellent mechanical properties: The three-dimensional steel wire mesh structure formed by welding steel wire forks and steel wire mesh panels gives the integrated insulation panel high tensile and compressive strength, effectively resisting external forces and preventing cracking, detachment, and hollowing. Its tensile strength can reach 0.5-1.0 MPa, and its compressive strength can reach 1.0-2.0 MPa.

[0016] 3. Excellent fire resistance: The inorganic vitrified microsphere board used in the inorganic insulation board layer is a non-combustible material. After being combined with waterproof cement mortar, the thickness reaches 50mm, which significantly improves the fire resistance rating of the integrated insulation board, reaching the Class A fire protection standard, effectively avoiding fire hazards and ensuring building safety.

[0017] 4. Convenient and efficient construction: Utilizing a prefabricated construction method, it allows for on-site processing and cutting to adapt to different building structures and construction needs, significantly shortening the construction cycle and reducing construction costs. Compared with traditional insulation systems, the construction period can be shortened by approximately 30%-50%.

[0018] 5. Environmentally friendly and sustainable: This utility model provides a new type of low-carbon building insulation integrated panel with non-toxic and harmless raw materials that meet environmental protection standards. It also has low energy consumption during production and use, which is in line with the concept of green building and sustainable development and helps to reduce the impact on the environment.
