Description

Technical Field

[0001] This invention relates to the field of building materials technology, specifically to a wall insulation structure. Background Technology

[0002] Wall insulation is key to building energy conservation, but existing wall insulation structures have many core defects, making it difficult to meet the requirements of high-efficiency insulation and long-term stability: 1. The main body of the insulation board is mostly made of one-piece molded insulation board, which cannot specifically block heat radiation, heat convection and heat conduction. The insulation efficiency is limited, and temperature changes can easily cause air pressure imbalance and structural cracking. Second: Poor sealing reliability of the joints between insulation boards, which easily leads to leakage and thermal bridging; Third: The insulation board is mostly fixed to the wall with expansion bolts, which is a complicated process that can easily damage the insulation structure and create thermal bridges. In addition, the substrate has poor compatibility and maintenance requires destructive disassembly.

[0003] Therefore, we propose a wall insulation structure. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a wall insulation structure.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a wall insulation structure, including an insulation board body and multiple bases embedded in the wall, and an insulation unit, including a cavity 1, a cavity 2 and a cavity 3 sequentially opened from left to right in the insulation board body for buffering thermal expansion and contraction caused by temperature changes. An air hole 1 for air circulation is opened between cavity 1 and cavity 2, and an air hole 2 for air circulation is opened between cavity 2 and cavity 3. Cavity 2 also has a through hole for connecting to the outside. The base is provided with a connecting unit for connecting to the insulation board body. Through the operation of the above components, heat transfer can be suppressed, and the air pressure of the three cavities can be synchronously balanced through the coordinated operation of air hole 1, air hole 2 and through hole.

[0006] Furthermore, a boss is provided on one side of the insulation board body, and a groove that mates with the boss is provided on the other side of the insulation board body. The boss has a gas venting and pressure relief channel, and the inner wall of the groove has a channel groove corresponding to the gas venting and pressure relief channel. When the temperature changes and causes the air in cavity one, cavity two and cavity three to expand synchronously, the air pressure in the cavity slowly increases, and the high-pressure gas slowly overflows through the gas venting and pressure relief channel to achieve passive pressure relief and avoid excessive pressure in the cavity from damaging the sealing structure. When the temperature decreases and the air pressure in the cavity decreases, a small amount of external gas enters the cavity through the gas venting and pressure relief channel to achieve dynamic air pressure balance.

[0007] Furthermore, the first cavity has an elliptical structure, and the major axis of the first cavity is consistent with the length direction of the insulation board body. The second cavity consists of multiple interconnected rhomboid cavities, and the third cavity consists of multiple interconnected circular cavities. Through the cooperation of the above components, the thermal bridge area of ​​the cavity wall can be reduced.

[0008] Furthermore, the edge of the boss is provided with an elastic anti-seepage flange, which is made of rubber and prefabricated integrally with the side of the boss. When the elastic anti-seepage flange is squeezed, it fits tightly against the inner wall of the groove to form a sealing barrier.

[0009] Furthermore, the connecting unit includes a lock seat disposed on one side of the base and abutting against the wall, and multiple connecting rods fixed between the base and the lock seat. Multiple connecting parts corresponding to the lock seat are fixed on the inner side of the insulation board body. The connecting parts have installation grooves on both sides at the end away from the insulation board body. Sliders are slidably connected to both sides inside the installation grooves. Multiple springs are fixed between two sliders. A locking block with its other end extending to the outside of the connecting part is fixed on the side of the slider away from the spring. The lock seat has a connecting groove at the end away from the connecting rod that slides with the connecting part. Through the operation of the above components, it is convenient for construction personnel to install the insulation board.

[0010] Furthermore, the connecting part has connecting grooves on both sides that communicate with the mounting groove. The locking block slides inside the adjacent connecting groove, and the locking block can be flexibly moved through the connecting groove.

[0011] Furthermore, the locking block is a trapezoidal block that engages with the connecting groove, allowing it to enter the connecting groove through the trapezoidal structure of the locking block.

[0012] Furthermore, the outer side of the insulation board body is provided with a radiation-proof coating, and the inner side of the insulation board body is provided with insulation cotton. The coating is made of materials such as polytetrafluoroethylene or silicone resin, which can further improve the insulation effect. The thickness of the insulation cotton is the distance from the insulation board body to the wall.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention suppresses heat transfer through the coordinated operation of three cavities. The coordinated operation of vent one, vent two, and through holes achieves synchronous pressure balance in the three cavities, solving the problems of incomplete insulation and easy damage of traditional single-cavity structures.

[0014] 2. This invention achieves seamless splicing between insulation boards through the cooperation of bosses and grooves, eliminating thermal bridges and leakage at the splicing gaps. It also solves the problems of cracking and sealing failure caused by air pressure imbalance in traditional splicing structures, significantly improving the long-term stability of the insulation system.

[0015] 3. This invention makes it convenient for construction workers to install insulation boards, simplifies the installation process, and avoids the generation of thermal bridges; at the same time, the press-locking mechanism can directly achieve seamless splicing of adjacent insulation boards, solving the problem that traditional expansion screws cannot be installed seamlessly.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Combination Figure 1This embodiment of a wall insulation structure includes an insulation board body 1 and multiple bases 15 embedded in the wall. The insulation unit includes, from left to right, cavities 2, 3, and 4, sequentially formed within the insulation board body 1 to buffer thermal expansion and contraction caused by temperature changes. During installation, cavity 2 faces outwards, and cavity 4 is close to the wall surface. Because the outermost layer of the insulation board body 1 is greatly affected by external temperature and experiences drastic temperature fluctuations, cavity 2 can buffer thermal expansion and contraction caused by temperature changes, reducing structural stress. Cavity 3, through irregular... The cross section further disrupts the airflow trajectory and suppresses thermal convection. Cavity 3 4 maximizes the locking of still air and strengthens the blocking of heat conduction. A vent 1 5 for air circulation is opened between cavity 1 2 and cavity 2 3, and a vent 2 6 for air circulation is opened between cavity 2 3 and cavity 3 4. Cavity 2 3 also has a through hole 7 connecting to the outside. Through the through hole 7, the airflow can be reduced and foreign objects or dust from the outside can be prevented from entering the interior of the insulation board body 1. The base 15 is provided with a connecting unit for connecting the insulation board body 1.

[0020] The implementation principle of a wall insulation structure in this application embodiment is as follows: Through the gradient structure design of cavity 1 (2), cavity 2 (3), and cavity 3 (4), precise matching of heat transfer suppression is achieved. Cavity 1 (2) weakens heat radiation by using multiple reflections on curved surfaces, and the large-size air layer forms a thermal inertia buffer layer, reducing the impact of drastic fluctuations in outdoor temperature on the indoor environment. The irregular cross-section of cavity 2 (3) divides the convection vortex, suppressing heat convection and extending the heat conduction path. The inner circular small chamber of cavity 3 (4) maximizes the locking of still air, strengthening the heat conduction blocking. The cooperation of cavity 1 (2), cavity 2 (3), and cavity 3 (4) forms a multi-barrier of radiation weakening, convection suppression, and heat conduction blocking. The air pressure is synchronously balanced through vent 1 (5), vent 2 (6), and through hole 7, solving the problems of incomplete insulation and easy damage of traditional single-chamber insulation.

[0021] A boss 9 is provided on one side of the insulation board body 1, and a groove 10 that mates with the boss 9 is provided on the other side of the insulation board body 1. The boss 9 has a gas venting and pressure relief channel 8, and the inner wall of the groove 10 has a channel groove 11 that corresponds to the gas venting and pressure relief channel 8. The gas venting and pressure relief channel 8 and the channel groove 11 on the adjacent insulation board body 1 are connected to form a complete gas venting channel. When the temperature changes and causes the air in cavity 1 2, cavity 2 3 and cavity 3 4 to expand synchronously, the air pressure in the cavity slowly increases, and the high-pressure gas slowly overflows through the gas venting and pressure relief channel 8 to achieve passive pressure relief and avoid excessive pressure in the cavity from damaging the sealing structure. When the temperature decreases and the air pressure in the cavity decreases, a small amount of external gas enters the cavity through the gas venting and pressure relief channel to achieve dynamic air pressure balance. The problem of thermal expansion and contraction air pressure can be solved without the need for a valve body structure.

[0022] Cavity 1 (2) has an elliptical structure, with its major axis aligned with the length of the insulation board body 1. Cavity 2 (3) consists of multiple interconnected rhomboid cavities, and Cavity 3 (4) consists of multiple interconnected circular cavities. The elliptical cavities of Cavity 1 (2) suppress thermal radiation. The curved surface of the ellipse causes solar radiation / ambient thermal radiation to be reflected multiple times on the cavity wall surface, extending the radiation path. The large-sized cavity has a thicker static air layer, forming a thermal inertia buffer layer. When the outdoor temperature fluctuates drastically, the heat capacity of the air layer can absorb or release heat, reducing the rate of temperature change and decreasing the instantaneous heat flux density through the insulation board, thus preventing rapid fluctuations in indoor temperature. The rhomboid cavities of Cavity 2 (3) suppress thermal convection. The irregular cross-section of the rhombus disrupts the continuous boundary layer of natural air convection. In a traditional rectangular cavity, heated air rises along the wall to form stable vortices. However, the broken wall surface of the rhomboid cavity divides the convective vortices into smaller vortices. These vortices collide and cancel each other out, significantly reducing the flow velocity. The zigzag wall surface changes the heat conduction path through the chamber wall from a straight line to a zigzag line, extending the path length. At the same time, the air pores 5, 6, and through holes 7 of the partition wall achieve air pressure balance in each chamber, avoiding stress damage to the chamber wall caused by temperature changes and maintaining the integrity of the insulation structure. The small circular chamber of the third chamber 4 inhibits heat transfer. The small size of the small circular chamber means that the air inside the chamber is almost absolutely still, and heat transfer is mainly by pure conduction. In addition, the chamber wall with a circular cross-section is subjected to uniform stress, and a thinner chamber wall can be used to reduce the thermal bridge area of ​​the chamber wall.

[0023] The edge of the boss 9 is provided with an elastic anti-seepage flange. The elastic anti-seepage flange is made of rubber and is prefabricated as an integral part of the side of the boss 9. When the boss 9 is embedded in the groove 10, the elastic anti-seepage flange is squeezed and fits tightly against the inner wall of the groove 10 to form a sealing barrier.

[0024] Example 2: Combination Figure 2 and Figure 3This embodiment, based on Embodiment 1, further improves upon the following: the connecting unit includes a lock seat 16 disposed on one side of the base 15 and abutting against the wall, and multiple connecting rods fixed between the base 15 and the lock seat 16. Multiple connecting portions 14 corresponding to the lock seat 16 are fixed to the inner side of the insulation board body 1. Mounting grooves 18 are provided on both sides of the connecting portion 14 away from the insulation board body 1. Sliding sliders 19 are slidably connected to both sides inside the mounting grooves 18. Multiple springs 21 are fixed between two sliders 19. A locking block 20, with its other end extending through to the outside of the connecting portion 14, is fixed on the side of the slider 19 away from the spring 21. A connecting groove 17 that slidably engages with the connecting portion 14 is provided at the end of the lock seat 16 away from the connecting rods. When the insulation board body 1 needs to be installed on the wall, the connecting part 14 on the insulation board body 1 can be inserted into the connecting groove 17 on the lock seat 16. When the connecting part 14 enters the lock seat 16, the locking block 20 will abut against the lock seat 16. Through the sliding cooperation of the slider 19 and the mounting groove 18, and through the cooperation of the spring 21, the locking block 20 will be moved. After the locking block 20 enters the mounting groove 18, and after the connecting part 14 enters the connecting groove 17, through the sliding cooperation of the slider 19 and the mounting groove 18, and through the elasticity of the spring 21, the locking block 20 will be pushed to reset. When the locking block 20 abuts against the inner wall of the connecting groove 17, the insulation board body 1 is installed on the wall.

[0025] The connecting part 14 has connecting grooves 22 on both sides that communicate with the mounting groove 18. The locking block 20 slides inside the adjacent connecting groove 22, and the locking block 20 can be flexibly moved through the connecting groove 22.

[0026] The locking block 20 is a trapezoidal block that engages with the connecting groove 17. The trapezoidal locking block 20 can be inserted into the connecting groove 17.

[0027] The outer side of the insulation board body 1 is provided with a radiation-proof coating 12, and the inner side of the insulation board body 1 is provided with insulation cotton 13. The coating 12 is made of polytetrafluoroethylene or silicone resin and other materials, which can further improve the insulation effect. The thickness of the insulation cotton 13 is the distance from the insulation board body 1 to the wall.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
