Description

Technical Field

[0001] This utility model relates to the field of building energy conservation technology, specifically a building insulation structure that reduces energy consumption. Background Technology

[0002] Building insulation structures refer to structures that achieve thermal insulation and protection functions through multi-layer composite systems. Their core purpose is to reduce the dissipation of heat from the interior of a building to the exterior, thereby creating a suitable indoor thermal environment and saving energy. Building insulation structures are widely used in various building fields, especially in cold regions, where they can effectively prevent indoor heat loss and improve the building's thermal insulation performance.

[0003] Currently, traditional building insulation structures mostly use a single material layer, such as polystyrene board or rock wool. However, this often results in excessively high thermal conductivity, and some composite structures are complex to construct, increasing costs for users and making it difficult to balance insulation performance and economy. Therefore, we propose a building insulation structure that reduces energy consumption to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a building insulation structure that reduces energy consumption, thereby solving the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a building insulation structure for reducing energy consumption, comprising an integral insulation wall, wherein the integral insulation wall comprises a base wall, the outer surface of the base wall is provided with a first insulation layer, a second insulation layer is provided on the side of the first insulation layer away from the base wall, and a protective finishing layer is provided on the side of the second insulation layer away from the first insulation layer.

[0006] In a further embodiment, the outer surface of the base wall is coated with a moisture-proof and vapor-barrier layer, the outer surface of the moisture-proof and vapor-barrier layer is closely attached to the outer surface of the first insulation layer, and the outer surface of the base wall is provided with an L-shaped basalt fiber insulation board.

[0007] In a further embodiment, the first insulation layer includes an aerogel felt with beveled edges, an outer surface covered with a reflective film, an outer surface of the reflective film with a nano-titanium dioxide coating, an outer surface of the reflective film laid in a wavy pattern, and an outer surface of the reflective film with plastic clips.

[0008] In a further embodiment, the outer surface of the reflective film is fixed to the outer surface of the aerogel felt by plastic clips, and the outer surface of the reflective film and the outer surface of the second insulation layer form an air layer, and the outer surface of the reflective film is provided with a mating block.

[0011] In a further embodiment, the protective finishing layer is provided with an elastic coating layer, and PVC corner protectors are provided at the inside and outside corners of the entire insulation wall.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device employs a dual insulation synergy mechanism. The first insulation layer combines aerogel felt with a reflective film, laid in a wavy pattern to increase heat reflection efficiency to over 92%. This, combined with the second insulation layer of graphite polystyrene board, forms a secondary barrier, reducing the overall heat transfer coefficient by 40% and effectively improving the structure's thermal performance. Simultaneously, a moisture-proof vapor barrier layer and L-shaped basalt fiberboard form a composite base layer, significantly reducing water vapor permeability. The mechanical connection method using plastic clips and mounting nails achieves wind pressure resistance of 5.0 kPa, effectively enhancing the device's moisture resistance and earthquake resistance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figures 1-5 As shown, this utility model provides a technical solution for a building insulation structure that reduces energy consumption, including an integral insulation wall 1, which includes a base wall 2. The outer surface of the base wall 2 is coated with a moisture-proof vapor barrier layer 201, which is tightly bonded to the outer surface of the first insulation layer 4. An L-shaped basalt fiber insulation board 3 is provided on the outer surface of the base wall 2. The base wall 2 serves as the main body, with the moisture-proof vapor barrier layer 201 and the L-shaped basalt fiber insulation board 3. The L-shaped basalt fiber insulation board 3 is used as the first insulation barrier. Its unique L-shaped cross-section design enhances the mechanical interlocking force with the wall. The moisture-proof vapor barrier layer 201 is made of high-molecular polymer coating, and the basalt fiber material meets the Class A fire resistance standard with a fire resistance limit of ≥2 hours. A composite interface is formed between the moisture-proof layer and the insulation board, and the cold bridge effect of traditional structures is eliminated through the tightly bonded structure.

[0022] Through the synergistic effect of the L-shaped basalt fiber insulation board 3 and the first insulation layer 4, the overall thermal conductivity of the wall is reduced to 0.1 W / (m²). 2 Below ·K), it saves more than 30% energy compared to traditional insulation structures, significantly reducing building heating and cooling energy consumption. The composite interface between the moisture-proof vapor barrier layer 201 and the L-shaped insulation board 3 reduces water vapor penetration by 95%, preventing condensation inside the wall and extending the service life of the insulation material.

[0023] The outer surface of the base wall 2 is provided with a first insulation layer 4, which includes an aerogel felt 401. The edges of the aerogel felt 401 are beveled. The outer surface of the aerogel felt 401 is covered with a reflective film 402. The outer surface of the reflective film 402 is coated with a nano-titanium dioxide coating. The outer surface of the reflective film 402 is laid in a wavy pattern. The outer surface of the reflective film 402 is provided with plastic clips 404, which fix the outer surface of the reflective film 402 to the outer surface of the aerogel felt 401. An air layer 403 is formed between the outer surface of the reflective film 402 and the outer surface of the second insulation layer 5. The outer surface of the reflective film 402 is provided with a connecting block 405. The first insulation layer 4 is mainly composed of aerogel felt 401, which has a functional reflective film 402 and an air layer 403. It is connected by plastic buckles 404 and mating blocks 405. The thermal conductivity of the aerogel felt 401 is 0.018 watts per meter Kelvin when the thickness is only 10mm. The reflective film 402 is laid in a wavy pattern, which increases the effective reflective area by 35%. At the same time, the nano titanium dioxide coating has a photocatalytic self-cleaning function, which reduces the pollution coefficient by 60%. The bevel edge design reduces the heat loss at the joint by 42%, and the elastic fixing method of the plastic buckles 404 allows for 3-5mm thermal displacement compensation.

[0024] Through the synergistic effect of aerogel felt 401 and corrugated reflective film 402, the overall thermal conductivity of the insulation system is ≤0.015W / (m·K), achieving energy savings of over 40% compared to traditional insulation structures. The bevel design and the air layer 403 further reduce heat transfer at joints and between layers, allowing the overall heat transfer coefficient K of the wall to be controlled at 0.15W / (m·K). 2 The plastic clips are 404 with elastic fastening, which effectively compensates for the thermal expansion and contraction of the material (linear expansion coefficient ≤3×10-5 / ℃), avoiding the risk of cracking caused by stress concentration.

[0025] A second insulation layer 5 is provided on the side of the first insulation layer 4 away from the base wall 2. A protective finishing layer 6 is provided on the side of the second insulation layer 5 away from the first insulation layer 4. The second insulation layer 5 includes a graphite polystyrene board 501. The outer surface of the graphite polystyrene board 501 has mounting holes 504, and mounting nails 503 are provided inside the mounting holes 504. The size of the mounting nails 503 is adapted to the mating block 405. The outer surface of the graphite polystyrene board 501 is provided with a crack-resistant mortar mesh layer 502. The outer surface of the protective finishing layer 6 is provided with an elastic coating layer. PVC corner protectors 7 are provided at the internal and external corners of the insulation wall 1. The main component of the second insulation layer 5 is the graphite polystyrene board 501, with a reinforcing layer of crack-resistant mortar mesh layer 502, connected through the mounting holes 504 and mounting nails 503. The graphite polystyrene board 501 has an oxygen index ≥30% and a thermal conductivity of 0.033 watts per meter Kelvin. The crack-resistant mortar mesh layer 502 is also provided. The mesh layer 502 uses 160g / ㎡ fiberglass mesh with a cracking stress ≥3000N / 50mm. The tapered design of the mounting holes 504 achieves an installation accuracy of ±2mm. Through the insertion structure of the mounting nails 503 and the connecting blocks 405, a three-dimensional adjustable connection system is formed. The elastic coating has a breaking elongation of ≥300%, adapting to temperature differences from -40℃ to 80℃. The PVC corner protectors 7 feature a rounded corner design with an impact resistance of 10J. The overall system's weather resistance has passed a 6000-hour artificial aging test. The flexible transition structure between the protective finishing layer 6 and the second insulation layer 5 effectively disperses stress concentration. The moisture-proof layer to the insulation board interface uses a combination of polymer mortar wet application and mechanical anchoring for double fixation. The reflective film 402 to the polystyrene board interface uses a composite connection method of snap-fit ​​and nailing. The corner protector nodes are pre-embedded in the crack-resistant mortar layer, forming continuous protection.

[0026] Through the flexible transition structure of the elastic coating layer (elongation at break ≥300%, adaptable to temperature difference of -40℃~80℃) and the crack-resistant mortar mesh layer 502, the stress concentration caused by temperature deformation is effectively dispersed. The entire system design from the moisture-proof vapor barrier layer 201 to the protective finishing layer 6, through material performance matching and interface structure optimization, reduces building energy consumption by more than 45% compared with traditional methods, and extends the overall system maintenance cycle to 5 years / time, reducing the later operation and maintenance cost by 35%.

[0027] The working principle of this utility model is as follows:

[0028] When using this device, the operator first applies a moisture-proof and vapor-barrier layer 201 to the outer surface of the base wall 2 and installs an L-shaped basalt fiber insulation board 3. Then, the aerogel felt 401 of the first insulation layer 4 is laid and covered with a wavy reflective film 402. An air layer 403 is formed by fixing it with plastic clips 404. Next, the graphite polystyrene board 501 of the second insulation layer 5 is installed and connected to the connecting block 405 by mounting nails 503. Finally, a crack-resistant mortar mesh layer 502 and an elastic coating protective finishing layer 6 are applied, and PVC corner protectors 7 are added at the inside and outside corners to complete the overall construction. Through the synergistic effect of the multi-layer composite structure, moisture is first blocked, then a double insulation system is established, and finally, protection is strengthened, achieving a balance between convenient construction and efficient insulation.
