Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation wall panels, in particular to an assembled vitrified micro-bead thermal insulation wall panel. Background Art

[0002] Vitrified microspheres have a microporous structure with a large amount of gas retained inside, forming a microporous structure with good thermal insulation properties. Vitrified microspheres are often used as the main aggregate and mixed with cement, lime and other gelling materials and various admixtures to form vitrified microsphere insulation mortar, which is used for interior and exterior wall insulation of reinforced concrete, aerated concrete blocks, porous bricks, sand-lime bricks and other walls.

[0003] However, due to the large surface area of ​​​​glass beads, they easily absorb moisture from the surrounding environment, resulting in excessive humidity in the insulation layer, which in turn affects the insulation effect and service life. They are also easy to separate from cement mortar, which may cause local bulging or peeling of the mortar surface, thereby affecting the bonding effect with other protective layers or decorative layers, and are prone to cracking after use or construction.

[0004] To this end, we propose an assembled vitrified microbead insulation wall panel to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0021] Reference Figure 1-Figure 4As shown, an assembled glass bead insulation wall panel includes a core insulation layer 1, and a reinforcement structure layer 2 is provided inside the core insulation layer 1. The reinforcement structure layer 2 is used to provide strength support for the core insulation layer 1, wherein the reinforcement structure layer 2 includes a first fiber grid 21 and a reinforcement keel 22 connected to the first fiber grid 21. During production, the core insulation layer 1 material can be laid in a mold to form a certain thickness and flatness, and the first fiber grid 21 can be laid flatly on the insulation core layer to ensure that the grid completely covers the insulation layer without wrinkles and overlaps. Then, the reinforcement keel 22 is installed on the first fiber grid 21 according to design requirements. The spacing and arrangement of the reinforcement keels 22 should be reasonably designed according to the size, strength requirements and use environment of the wall panel, such as the number of keels per unit plane area is not less than three groups, etc. After the reinforcement structure layer is installed 2, continue to lay the core insulation layer 1 on it, so that the reinforced structural layer 2 is completely wrapped inside the core insulation layer 1, ensure that the core insulation layer 1 and the reinforced structural layer 2 are tightly combined without gaps and stratification, so as to improve the overall strength and impact resistance of the wall panel, reduce the risk of damage, and extend its service life. The reinforced keel 22 includes multiple connectors 221 and reinforced ties 222 connected between two adjacent connectors 221. The connectors 221 and the reinforced ties 222 can be made of light-weight and high-strength materials such as aluminum alloy and light steel, and the various connectors 221 can be connected together through the reinforced ties 222 to form an integral frame structure, which can improve the stability of the reinforced keel 22 and reduce deformation and displacement when subjected to external forces. The decorative surface layer 4 can be a paint surface layer with decorative properties or a facing brick surface, etc.

[0022] Since thermal insulation materials such as glass beads can perform well in a dry state, their thermal insulation performance will drop significantly once they are penetrated by water vapor. When external water vapor invades the thermal insulation core layer, it will reduce the performance of the thermal insulation material. Therefore, a protective surface layer 3 and a decorative surface layer 4 are respectively provided on both sides of the core thermal insulation layer 1, and a waterproof vapor barrier layer 5 is provided between the protective surface layer 3 and the reinforced structural layer 2. The waterproof vapor barrier layer 5 is used to allow water vapor to be discharged while preventing external water vapor from entering. During use, the building will be affected by water vapor in the external environment, such as rainwater, moisture in the air, etc. The waterproof vapor barrier layer 5 can effectively prevent these external water vapor from entering the core thermal insulation layer 1 of the prefabricated wall panel.

[0023] Furthermore, the waterproof vapor barrier layer 5 adopts a polymer waterproof membrane, such as polyethylene polypropylene waterproof membrane, SBS modified asphalt waterproof membrane, etc. The tight structure and low permeability of these materials can prevent moisture from entering the interior of the wall through diffusion, infiltration, etc., and has good waterproof and vapor barrier properties. The protective surface layer 3 adopts fiber-reinforced cement board. The fiber-reinforced cement board can be made of cement as the main gelling material and an appropriate amount of fiber-reinforced material. It has high strength and can withstand certain external force impact and wear to protect the internal structure of the wall. At the same time, the fiber-reinforced cement board has good fire resistance and can play a certain barrier role in the event of a fire, thereby improving the safety of the building.

[0024] Among them, reference Figure 1 As shown, a second fiber mesh 7 is provided between the core insulation layer 1 and the decorative surface layer 4 to increase the bonding strength between the decorative layer and the core insulation layer 1, and prevent the decorative surface layer 4 from falling off, cracking and other problems during use. For example, when the wall is subjected to temperature changes, humidity changes or slight mechanical shocks, the second fiber mesh 7 can play a buffering role, reducing the stress concentration between the decorative surface layer 4 and the core insulation layer 1, thereby improving the overall stability of the wall. It should be noted that the first fiber mesh 21 and the second fiber mesh 7 can both be made of mesh materials made of alkali-resistant glass fiber as raw materials, etc., which can maintain stable performance in alkaline environments and will not be corroded or damaged due to contact with alkaline materials such as cement and lime.

[0025] Further, refer to Figure 2 As shown, a plurality of slots 6 are equidistantly provided on the waterproof vapor barrier layer 5, and a positioning strip 61 that can be inserted into the slot 6 is provided on the side of the protective surface layer 3 close to the waterproof vapor barrier layer 5, wherein the slot 6 and the positioning strip 61 can be integrally formed during production. When the protective surface layer 3 is connected to the waterproof vapor barrier layer 5, the slot 6 and the positioning strip 61 can be aligned, and then the two layers of material are connected together by sliding, extruding, etc., and in order to enhance the stability of the connection, sealant or other filling materials can be added to the slot 6 to prevent relative sliding and moisture infiltration between the two layers of material, thereby improving the stability of the connection between the two.

[0026] Furthermore, the thickness ratio of the reinforced structural layer 2, the core insulation layer 1, and the waterproof vapor barrier layer 5 is 4-6:8-14:2-4. The reinforced structural layer 2 provides strength support for the core insulation layer 1 and needs to have a certain thickness to ensure the overall bearing capacity and stability of the wall and the core insulation layer 1. The appropriate thickness can resist external loads and ensure the safety performance of the wall. The core insulation layer 1 is the key component of the wall panel for thermal insulation. According to the provisions of the "Energy-Saving Design Standard for Residential Buildings in Hot Summer and Cold Winter Areas" (JGJ134-2022) and the calculation requirements of the thermal conductivity coefficient, the core insulation layer 1 needs to have a certain thickness to achieve the ideal insulation effect. The insulation layer thickness within this ratio range can significantly improve the thermal insulation performance of the wall and reduce energy consumption. An excessively thick waterproof vapor barrier layer 5 will increase material cost and construction difficulty, while an excessively thin waterproof vapor barrier layer 5 may not achieve the expected waterproof effect. The appropriate thickness can ensure the durability and waterproof effect of the waterproof vapor barrier layer 5, preventing damage to the wall due to moisture penetration.
