Description

Technical Field

[0002] We produce various materials and related technologies that can effectively prevent heat transfer, maintain stable indoor temperature, and reduce building energy consumption. Extruded polystyrene (XPS) boards, with their relatively excellent thermal insulation performance, are widely used in the construction industry for wall insulation, roof insulation, and cold chain logistics facilities.

[0003] In practical use, when subjected to large external impacts or long-term heavy pressure, the closed-cell structure inside the board is easily damaged. For example, during construction, improper handling or installation may cause cracks in the extruded polystyrene board due to collisions. Over time, these cracks will gradually expand, eventually leading to the board breaking and seriously affecting its compressive strength. Therefore, we have introduced a heat-insulating extruded polystyrene board. Utility Model Content

The upper front and upper rear parts of the side panel frame both have positioning grooves 2 extending through the bottom of the side panel frame. T-shaped insert rods are inserted into several positioning grooves 2 on the front side and several positioning grooves 2 on the rear side. The side panel frame is located on the left side of the heat insulation plate 2.

[0014] Preferably, the pressure-resistant mechanism includes a mating pressing plate, with positioning grooves at the four corners of the upper end of the mating pressing plate, and several flower-shaped grooves at the front and rear of the upper end of the mating pressing plate, and the mating pressing plate is tightly attached to the surface of the elastic rubber block.

[0015] By adopting the above technical solution: the elastic rubber block uses natural rubber, providing good elastic deformation capability.

[0016] Preferably, the inner wall shape of the flower-shaped groove is adapted to the outer surface contour of the flower-shaped column, and the top height of the flower-shaped column is lower than the upper surface of the mating and pressing plate.

[0017] Preferably, the compression stroke of the elastic rubber block is greater than the initial distance between the top of the flower-shaped column and the bottom of the flower-shaped groove.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In this utility model, through the ingenious design of the elastic rubber block and the flower-shaped column in the anti-compression mechanism, when the pressure is small, the elastic strip inside the elastic rubber block, the elastic ball on the outer surface, and the internal cavity work together to elastically deform, effectively buffering the pressure and avoiding the instantaneous concentrated impact of pressure on the board, reducing the risk of cracking of the board. As the pressure increases, the flower-shaped column shares the pressure and transmits it to the anti-compression plate, and finally to the heat insulation board, so that the entire heat insulation extruded board can withstand greater pressure, significantly improving the problem of damage and breakage of the closed-cell structure of the board caused by external impact or long-term heavy pressure, and improving the compressive strength.

[0022] 2. In this utility model, the side frame of the installation mechanism is precisely connected to the side of the heat insulation plate 2, the pressure-resistant mechanism, the pressure-resistant mechanism and the heat insulation plate 1 through connecting groove 1, connecting groove 2, connecting groove 3 and connecting groove 4 respectively to form an interference fit. At the same time, the T-shaped plug passes through the positioning groove 2 on both sides of the heat insulation plate 1, the pressure-resistant mechanism, the pressure-resistant mechanism and the heat insulation plate 2, and firmly fixes the components together. This installation method not only achieves convenient and efficient installation, but also greatly enhances the stability of the overall structure.

[0023] 3. In this utility model, heat insulation board one and heat insulation board two together constitute a highly efficient heat insulation system, effectively preventing heat transfer and maintaining temperature stability. At the same time, the pressure-resistant mechanism and the pressure-resistant mechanism work closely together, from the buffering of the elastic rubber block to the pressure transmission of the flower-shaped column, giving the board good pressure resistance. The axes of positioning groove five and positioning groove six coincide and their inner diameters are the same. This design detail ensures the positioning accuracy of the pressure-resistant mechanism and the pressure-resistant mechanism during installation, enabling each component to work together and achieve optimal performance. In addition, the embossed layer on the upper end of heat insulation board two not only increases surface friction but also improves heat insulation performance to a certain extent, reducing direct heat transfer. This heat-insulating extruded polystyrene board has excellent heat insulation performance and excellent pressure resistance, which can meet the dual functional requirements of heat-insulating extruded polystyrene board in different scenarios.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Please see Figure 1-5 This utility model provides a technical solution:

[0034] A heat-insulating extruded polystyrene board includes: a heat-insulating board 3 and a compression-resistant mechanism 7;

[0035] The upper end of the heat insulation board 3 is fixedly connected to the anti-compression mechanism 7;

[0036] The compression-resistant mechanism 7 includes a positioning groove 71, a buffer assembly 72, a flower-shaped column 73, and a compression-resistant plate 74;

[0037] The upper end of the compression plate 74 has positioning grooves 71 at each of the four corners. Several elastic rubber blocks 721 and several flower-shaped columns 73 are fixedly connected to the upper end of the compression plate 74.

[0038] A channel tube 722 is provided in the middle of the upper end of the elastic rubber block 721. Several elastic balls 724 are interlaced on the outer surface of the elastic rubber block 721. A cavity 725 is provided inside the elastic rubber block 721. Several elastic strips 723 are embedded in the inner wall of the elastic rubber block 721. The pressure-resistant mechanism 4 includes a mating pressing plate 41. Positioning grooves 42 are opened at the four corners of the upper end of the mating pressing plate 41. Several flower-shaped grooves 43 are opened at the front and rear of the upper end of the mating pressing plate 41. The mating pressing plate 41 is in close contact with the surface of the elastic rubber block 721. The inner wall shape of the flower-shaped groove 43 is adapted to the outer surface contour of the flower-shaped column 73. The top height of the flower-shaped column 73 is lower than the upper surface of the mating pressing plate 41. The compression stroke of the elastic rubber block 721 is greater than the initial distance between the top of the flower-shaped column 73 and the bottom of the flower-shaped groove 43. The axes of the positioning groove 5 71 and the positioning groove 6 42 coincide and their inner diameters are the same.

[0039] Through the above scheme: the pressure-resistant mechanism 7 plays a key role in the thermal insulation extruded polystyrene board. When external pressure is applied to the thermal insulation extruded polystyrene board, the pressure is transmitted through the upper components to the mating pressing plate 41 of the pressure-resistant mechanism 4. Since the mating pressing plate 41 is in close contact with the elastic rubber block 721, and the flower groove 43 is adapted to the flower column 73, the pressure is transmitted to the pressure-resistant mechanism 7 in two paths. When the pressure is small, the elastic rubber block 721 responds first due to its unique structure. The elastic strip 723 inside the elastic rubber block 721, the elastic balls 724 interspersed on the outer surface, and the internal cavity 725 work together to effectively buffer the pressure by using elastic deformation, avoiding concentrated pressure impact on the board. This buffering process can significantly reduce the risk of damage to the board caused by instantaneous pressure. As the pressure increases, the flower column 73 begins to bear the pressure. Under pressure, the pressure is further transmitted to the pressure-resistant plate 74. As the final pressure-bearing component, the pressure-resistant plate 74 transmits the pressure to the heat insulation plate 3, enabling the entire heat insulation extruded board to withstand greater pressure. The positioning grooves 71 at the four corners of the upper end of the pressure-resistant plate 74 and the positioning grooves 42 at the four corners of the upper end of the mating and pressing plate 41 have the same axis and the same inner diameter. This greatly improves the positioning accuracy of the pressure-resistant mechanism 7 and the pressure-resistant mechanism 4 during installation, ensuring the accuracy and stability of the connection of each component. The cooperation between the elastic rubber block 721 and the flower-shaped column 73 in the pressure-resistant mechanism 7, as well as the tight connection with the pressure-resistant mechanism 4, not only gives the heat insulation extruded board good pressure resistance, but also the compact and reasonable layout of each component allows the heat insulation extruded board to meet the dual requirements of heat insulation and pressure resistance in practical applications.

[0040] In this embodiment, a pressure-resistant mechanism 4 is fitted together on the outer surface of several flower-shaped columns 73. A heat insulation plate 2 5 is fixedly connected to the upper end of the pressure-resistant mechanism 4. An embossed layer 1 is coated on the upper end of the heat insulation plate 2 5. Positioning grooves 1 6 are opened at the four corners of the upper end of the heat insulation plate 2 5 and the four corners of the upper end of the heat insulation plate 3. Installation mechanisms 2 are snapped onto the left and right sides of the heat insulation plate 2 5, the left and right sides of the pressure-resistant mechanism 4, the left and right sides of the pressure-resistant mechanism 7 and the left and right sides of the heat insulation plate 3.

[0041] Through the above scheme: several flower-shaped columns 73 jointly support the pressure-resistant mechanism 4, and the two are connected by a sleeve connection. The unique outer surface contour of the flower-shaped column 73 is precisely matched with the flower-shaped groove 43 on the mating and pressing plate 41 in the pressure-resistant mechanism 4. When under pressure, the flower-shaped column 73 can evenly distribute the pressure to the pressure-resistant mechanism 4, ensuring the stable operation of the pressure-resistant mechanism 4. The upper end of the pressure-resistant mechanism 4 is fixedly connected to the heat insulation plate 2 5, further transmitting the pressure to the heat insulation plate 2 5. As part of the heat insulation layer, the heat insulation plate 2 5 works with the structure below to perform the heat insulation function. The embossed layer 1 at its upper end not only increases the surface friction, but also improves the heat insulation performance to a certain extent and reduces the direct transfer of heat. The heat insulation plate 2 5 and the heat insulation plate 1 3 are connected by positioning grooves at the four corners of the upper end. 6. Precise positioning facilitates installation and ensures accurate relative positioning of the two insulation boards in the vertical direction, resulting in more uniform and stable insulation effect. It is snapped into the left and right sides of the insulation board 2, the pressure-resistant mechanism 4, the pressure-resistant mechanism 7, and the insulation board 3. The connecting grooves on the side plate frame 21 are tightly engaged with the sides of the corresponding components. The T-shaped insert 22 passes through the positioning grooves 23 on both sides of each component, firmly fixing all components together. This allows the insulation extruded board to effectively resist pressure when facing external forces through the cooperation of the flower-shaped column 73 and the pressure-resistant mechanism 4. The insulation board 3 and the insulation board 2 ensure good insulation performance. The installation mechanism 2 ensures that the connection of each component is stable. Overall, it meets the requirements of insulation, pressure resistance and structural stability of the insulation extruded board in practical applications.

[0042] In this embodiment, the installation mechanism 2 includes a side plate frame 21. From top to bottom, the right end of the side plate frame 21 has a connecting groove 1 24, a connecting groove 25, a connecting groove 3 26, and a connecting groove 4 27. The upper front and upper rear parts of the side plate frame 21 both have a positioning groove 23 through the bottom of the side plate frame 21. T-shaped insert rods 22 are inserted into the several positioning grooves 23 on the front and rear sides. The side plate frame 21 is located on the left side of the heat insulation plate 2 5. The T-shaped insert rods 22 pass through the positioning grooves 23 on both sides of the heat insulation plate 1 3, the pressure-resistant mechanism 7, the pressure-resistant mechanism 4, and the heat insulation plate 2 5. The connecting grooves 1 24, 25, 3 26, and 4 27 form an interference fit with the sides of the heat insulation plate 2 5, the pressure-resistant mechanism 4, the pressure-resistant mechanism 7, and the heat insulation plate 1 3, respectively.

[0043] Through the above scheme: the installation mechanism 2 plays an indispensable role in the assembly of the heat-insulating extruded polystyrene board. During installation, the side frame 21 is placed on the left side of the second heat-insulating board 5. The connecting grooves 24, 25, 26, and 27, which are opened sequentially from top to bottom on its right end, are precisely aligned with the sides of the second heat-insulating board 5, the pressure-resistant mechanism 4, the pressure-resistant mechanism 7, and the first heat-insulating board 3, respectively. At the same time, the T-shaped insert 22 plays a further tightening role. The T-shaped insert 22 passes through the positioning groove 23 at the bottom of the upper front and rear of the side frame 21, and also passes through the positioning grooves 23 on both sides of the first heat-insulating board 3, the pressure-resistant mechanism 7, the pressure-resistant mechanism 4, and the second heat-insulating board 5. During the insertion process, the body of the T-shaped insert 22 and the positioning groove 23 are aligned. 3. The T-shaped head acts as a barrier on the outside of the side panel frame 21 to prevent the T-shaped plug 22 from falling off. This through-type installation method connects the main components of the thermal insulation extruded board into a whole, greatly enhancing the stability of the overall structure. The installation mechanism 2 achieves convenient and efficient installation of the components of the thermal insulation extruded board through the interference fit of the connecting groove 1 24, connecting groove 25, connecting groove 3 26 and connecting groove 4 27 and the through connection of the T-shaped plug 22. It also ensures that the structure is firm after installation, which can not only withstand a certain amount of external impact, but also ensures that the components will not easily loosen or separate during use. It can also effectively maintain the thermal insulation and compressive strength of the thermal insulation extruded board, meeting the dual requirements of product structural stability and functionality in practical applications.

[0044] It should be noted that this utility model is a heat-insulating extruded polystyrene board. When the heat-insulating extruded polystyrene board is working, when external pressure is applied to the embossed layer 1 on the heat insulation board 25, the pressure is first transmitted to the heat insulation board 25, and then to the mating pressing plate 41 of the pressure-resistant mechanism 4. Since the inner wall shape of the flower groove 43 is adapted to the outer surface contour of the flower column 73, the mating pressing plate 41 disperses the pressure to the flower column 73. At the same time, the mating pressing plate 41 is in close contact with the elastic rubber block 721, and the pressure is also applied to the elastic rubber block 721. Because the compression stroke of the elastic rubber block 721 is greater than the initial distance between the top of the flower column 73 and the bottom of the flower groove 43, the elastic rubber block 721 undergoes elastic deformation first when the pressure is small. The elastic strip 723 inside, the elastic ball 724 inserted on the outer surface, and the cavity 725 inside work together to buffer the pressure. As the pressure increases, the flower-shaped column 73 begins to bear the pressure, further transmitting it to the pressure-resistant plate 74, and finally to the heat insulation board 3. In terms of installation, the components are connected via the installation mechanism 2. The side frame 21 is located on the left side of the heat insulation board 5. The T-shaped insert 22 simultaneously passes through the positioning grooves 23 on both sides of the heat insulation board 3, the pressure-resistant mechanism 7, the pressure-resistant mechanism 4, and the heat insulation board 5. The connecting grooves 24, 25, 26, and 27 form an interference fit with the sides of the heat insulation board 5, the pressure-resistant mechanism 4, the pressure-resistant mechanism 7, and the heat insulation board 3, ensuring that each component is securely installed. Furthermore, the axes of the positioning groove 5 71 and the positioning groove 6 42 coincide and have the same inner diameter, facilitating precise positioning during installation and ensuring coordinated operation of all components. This allows the extruded polystyrene board to possess excellent heat insulation performance while also exhibiting outstanding pressure resistance.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
