Description

Technical Field

[0001] This invention relates to the field of wall insulation technology, and in particular to an integrated steel wire mesh composite insulation wall system and its construction method. Background Technology

[0002] The steel wire mesh composite insulation wall system is a new type of external wall insulation technology that integrates insulation, structure, and protection. Its core is to combine prefabricated three-dimensional steel wire mesh insulation panels in the factory with cast-in-place concrete on site to form a cavity-free, composite-load-bearing external wall system to achieve the building's insulation function.

[0003] During construction, existing insulation wall systems often have bolts and fixing ribs used for fixing that penetrate the insulation board, leading to a decrease in the insulation performance of the system. In addition, some insulation wall systems only have an insulation layer on one side, leaving the other side without insulation capacity. Furthermore, the existing wire mesh frame is not tightly bonded to the concrete, which may cause cracks in the insulation wall.

[0004] To address the aforementioned issues, we propose an integrated steel wire mesh composite insulation wall system and its construction method. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing an integrated steel wire mesh composite thermal insulation wall system and its construction method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an integrated steel wire mesh composite insulation wall system, comprising an inner wall panel, wherein fixing ribs are fixedly installed on both sides of the inner wall panel, a steel wire mesh skeleton is fixedly installed on the inner wall panel through the fixing ribs, an outer wall panel is fixedly cast on the outside of the steel wire mesh skeleton, and an insulation layer is fixedly installed between the steel wire mesh skeleton and the inner wall panel.

[0007] In the aforementioned integrated steel wire mesh composite insulation wall system, the insulation layer consists of an inner insulation board and an outer insulation foam, and the insulation board of the insulation layer is penetrated by fixing ribs.

[0008] In the aforementioned integrated steel wire mesh composite insulation wall system, an alkali-resistant fiberglass mesh is fixedly installed inside the outer wall panel. The steel wire mesh skeleton is made of double-sided galvanized steel wire mesh, and the steel wire mesh skeleton forms a three-dimensional space frame by obliquely inserting web wires, ensuring integrity and concrete bonding force.

[0009] In the aforementioned integrated steel wire mesh composite insulation wall system, the steel wire mesh frame is fixedly installed with fixing bolts and positioning supports.

[0010] The construction method for integrated steel wire mesh composite insulation wall includes the following steps: S1. Construction Preparation: Construction preparation includes material preparation and material handling: Materials required include: steel wire mesh insulation board, reinforcing bars, concrete, and fasteners; Material handling includes: arranging various components according to the wall size, prioritizing main specification boards, with a minimum board width of ≥200mm, and pre-cutting and numbering door and window openings and inside and outside corners to reduce on-site cutting; S2. Construction in progress: Wall reinforcement binding: Bind the vertical and horizontal reinforcement of the exterior wall and pass the inspection; install the inner protective layer spacers to ensure the accurate position of the reinforcement; add reinforcement at door and window openings, hidden columns and corners; and reserve pipeline grooves. Steel wire mesh insulation board installation: Position the boards according to the layout diagram, with tongue and groove joints between boards, ensuring tight seams with gaps ≤2mm, and strictly prohibiting through seams; at inside and outside corners, use L-shaped whole boards or cut and spliced ​​boards, and install L-shaped anchor bars: 6~8mm in diameter, 4 bars per square meter, one end inserted into the insulation board, the other end firmly tied to the wall reinforcement, with an anchoring depth ≥100mm, and reinforced around openings; install positioning supports: the spacing between each support bracket should be ≤600mm, ≥6 supports per square meter, used to control the thickness of the inner and outer concrete, prevent the insulation board from shifting, and ensure the protective layer (50~80mm on the outer side). Concrete pouring: Self-compacting concrete is used for the outer wall panel, and ordinary concrete is used for the inner wall panel. The concrete is poured and vibrated in layers, and the vibrator is kept away from the insulation board to prevent displacement or damage. The inner wall panel is poured first and then the outer wall panel. The two sides are poured symmetrically and simultaneously, with a height difference of ≤500mm, to avoid unilateral pressure squeezing the insulation board. Vibration is strengthened at openings and corners to ensure compaction and no honeycomb or pitting. S3. Acceptance: Ensure that the insulation board is installed in the center, firmly fixed, and with tight joints. Tilt, displacement, and damage are strictly prohibited. The web threads must not be exposed or cut, and the thickness must meet the design requirements and DB37 / T5147 and GB50411. Ensure that the concrete is dense and free of voids, and strictly prohibit under-vibration or over-vibration. The strength, density and appearance quality shall meet GB50204.

[0011] In the aforementioned integrated steel wire mesh composite insulation wall system, grooves are cut into the insulation board for installing water and electrical conduits. The water and electrical conduits must be firmly fixed, and it is strictly forbidden to cut the web wires. The pipe openings must be sealed to prevent grout leakage. PVC pipes are fitted on the outside of the fixing bolts, and the spacing between the fixing bolts is ≤600×600mm. The fixing bolts pass through the insulation board and the inner and outer templates. After tightening, the rigidity of the template and the insulation board must be ensured and the insulation board must be centered.

[0012] In the aforementioned integrated steel wire mesh composite insulation wall system, after the insulation wall is prepared, it is repaired to repair the joints, bolt holes, and damaged areas. The insulation wall needs to be maintained and repaired at the same time, and the joints, bolt holes, and damaged areas need to be repaired.

[0013] In the aforementioned integrated steel wire mesh composite insulation wall system, the insulation wall is made using a mold during the manufacturing process. The mold uses double steel pipe main ribs and square timber secondary ribs, which are fastened with tie bolts to ensure the verticality and flatness of the mold.

[0014] Compared with existing technologies, the advantages of this integrated steel wire mesh composite insulation wall system and its construction method are as follows: 1. The insulation layer consists of insulation board and insulating foam. After the insulation board is penetrated by structures such as fixing bolts, the insulating foam will cover the entire insulation board, fixing bolts and their connections, reducing the decrease in insulation performance caused by damage to the insulation pack, which is beneficial to the overall insulation of the wall system. At the same time, the insulation layer is installed on both sides of the inner wall panel, so that both sides of the entire insulation wall have insulation capacity, which is beneficial to its use. 2. By using structures such as diagonally inserted web wires to form a three-dimensional spatial framework of steel wire mesh skeleton, the integrity and bonding force with concrete are ensured, avoiding the situation where the steel wire mesh skeleton and concrete are not tightly bonded, which could lead to cracks in the insulation wall.

The insulation layer 2 consists of an inner insulation board and an outer insulation foam. The insulation board of the insulation layer 2 is penetrated by the fixing rib 4. The insulation foam wraps the insulation board, the fixing rib 4 and their connection inside, reducing the decrease in insulation performance caused by damage to the insulation pack, which is beneficial to the overall insulation of the wall system. The outer wall panel 5 is internally fixed with alkali-resistant fiberglass mesh. The wire mesh frame 3 is made of double-sided galvanized steel wire mesh, and the wire mesh frame 3 forms a three-dimensional space frame by obliquely inserting web wires, which ensures the integrity and bonding force with concrete and prevents cracks from appearing in the concrete outer wall panel 5. The wire mesh frame 3 is fixedly installed with fixing bolts and positioning supports to facilitate the pouring of concrete and the fixing and installation of the wire mesh frame 3. The construction method for integrated steel wire mesh composite insulation wall includes the following steps: S1. Construction Preparation: Construction preparation includes material preparation and material handling: Materials required include: steel wire mesh insulation board, reinforcing bars, concrete, and fasteners; Material handling includes: arranging various components according to the wall size, prioritizing main specification boards, with a minimum board width of ≥200mm, and pre-cutting and numbering door and window openings and inside and outside corners to reduce on-site cutting; S2. Construction in progress: Wall reinforcement binding: Bind the vertical and horizontal reinforcement of the exterior wall and pass the inspection; install the inner protective layer spacers to ensure the accurate position of the reinforcement; add reinforcement at door and window openings, hidden columns and corners; and reserve pipeline grooves. Steel wire mesh insulation board installation: Position the boards according to the layout diagram, with tongue and groove joints between boards, ensuring tight seams with gaps ≤2mm, and strictly prohibiting through seams; at inside and outside corners, use L-shaped whole boards or cut and spliced ​​boards, and install L-shaped anchor bars: 6~8mm in diameter, 4 bars per square meter, one end inserted into the insulation board, the other end firmly tied to the wall reinforcement, with an anchoring depth ≥100mm, and reinforced around openings; install positioning supports: the spacing between each support bracket should be ≤600mm, ≥6 supports per square meter, used to control the thickness of the inner and outer concrete, prevent the insulation board from shifting, and ensure the protective layer (50~80mm on the outer side). Concrete pouring: Self-compacting concrete is used for the outer wall panel 5, and ordinary concrete is used for the inner wall panel 1. The concrete is poured and vibrated in layers, and the vibrator is kept away from the insulation board to prevent displacement or damage. The inner wall panel 1 is poured first, followed by the outer wall panel 5. The two sides are poured symmetrically and simultaneously, with a height difference of ≤500mm, to avoid pressure on one side squeezing the insulation board. Vibration is strengthened at openings and corners to ensure compaction and no honeycomb or pitting. S3. Acceptance: Ensure that the insulation board is installed in the center, firmly fixed, and with tight joints. Tilt, displacement, and damage are strictly prohibited. The web threads must not be exposed or cut, and the thickness must meet the design requirements and DB37 / T5147 and GB50411. Ensure that the concrete is dense and free of voids, and strictly prohibit under-vibration or over-vibration. The strength, density, and appearance quality shall meet GB50204. Grooves are cut into the insulation board for installing water and electrical pipes. The water and electrical pipes must be firmly fixed, and the web threads must not be cut. The pipe openings must be sealed to prevent grout leakage. PVC pipes are fitted over the fixing bolts. The spacing between fixing bolts is ≤600×600mm. The fixing bolts pass through the insulation board and the inner and outer templates. After tightening, ensure the rigidity of the template and that the insulation board is centered. After the insulation wall is prepared, it is repaired, including repairing the joints, bolt holes, and damaged areas. The insulation wall needs to be cured and repaired at the same time. During the preparation of the insulation wall, a mold is used to facilitate its preparation. The mold adopts double steel pipe main ribs and square timber secondary ribs, which are fastened with tie bolts to ensure the verticality and flatness of the mold.

[0019] In this invention, the following steps are first prepared: steel wire mesh insulation board, reinforcing bars, concrete, fasteners, and other components are prepared. Then, these components are arranged according to the wall dimensions, prioritizing main specification boards with a minimum board width of ≥200mm. Door and window openings and internal / external corners are pre-cut and numbered to reduce on-site cutting. Next, the wall reinforcement is tied, including vertical and horizontal reinforcement of the exterior wall, and inspected for compliance. Inner protective layer spacers are installed to ensure accurate reinforcement placement. Additional reinforcement is added to door and window openings, concealed columns, and corners. Pipeline trenches are pre-reserved. Finally, the process continues... Installation of wire mesh insulation boards: Position the boards according to the layout diagram, using tongue-and-groove joints between boards, ensuring tight seams with gaps ≤2mm, and strictly prohibiting through seams; at inside and outside corners, use L-shaped whole boards or cut and spliced ​​boards, and install L-shaped anchor bars: 6~8mm in diameter, 4 bars per square meter, one end inserted into the insulation board, the other end firmly tied to the wall reinforcement, anchoring depth ≥100mm, with denser anchoring around openings; install positioning supports: each support bracket spacing ≤600mm, ≥6 per square meter, used to control the concrete on the inner and outer sides. The soil thickness should be controlled to prevent the insulation board from shifting and to ensure a protective layer (50-80mm on the outer side). Next, grooves should be cut into the insulation board for installing water and electrical pipes. The water and electrical pipes must be firmly fixed, and the web threads must not be cut. The pipe openings should be sealed to prevent grout leakage. PVC pipes should be fitted over the fixing bolts, and the spacing between the fixing bolts should be ≤600×600mm. The fixing bolts should pass through the insulation board and the inner and outer formwork. After tightening, ensure the rigidity of the formwork and that the insulation board is centered. Then, concrete should be poured: self-compacting concrete should be used for the outer wall panel 5. The inner wall panel 1 is made of ordinary concrete, and is poured and vibrated in layers. The vibrator should avoid the insulation board to prevent displacement or damage. The inner wall panel 1 is poured first, followed by the outer wall panel 5. Both sides are poured symmetrically and simultaneously, with a height difference of ≤500mm to avoid pressure on one side squeezing the insulation board. Vibration is strengthened at openings and corners to ensure compaction and no honeycomb or pitting. After pouring, the mold is removed, the insulation wall is cured, and finally the insulation wall is repaired, including repairing the joints, bolt holes, and damaged areas.
