Description

Technical Field

[0001] This utility model relates to the field of thermal insulation layer technology, and in particular to a rigid polyurethane foam thermal insulation and waterproof structure. Background Technology

[0002] Rigid polyurethane foam is a closed-cell rigid foam plastic. In the field of construction engineering, waterproofing layers and insulation layers are usually formed by hot pressing onto rigid polyurethane foam to create a composite board for insulation of building walls.

[0003] In existing technologies, after a period of use, the edges and corners of the structure are prone to warping. The gaps created by the warping will form thermal bridges, and the air convection will accelerate heat exchange. Furthermore, the gaps in the warped edges will become channels for rainwater to seep into the structure, which will reduce the thermal insulation and waterproofing effects of the structure. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rigid polyurethane foam thermal insulation and waterproof structure, which aims to improve the problem that the edges of the structure are prone to warping. The gaps created by the warping will form thermal bridges, and the air convection will accelerate heat exchange. In addition, the gaps of the warped edges will become rainwater infiltration channels, and rainwater will seep into the board, which will lead to a decrease in the thermal insulation and waterproof effect of the structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rigid polyurethane foam thermal insulation and waterproof structure, comprising an installation frame, an anti-warping component installed on one side of the installation frame, the anti-warping component comprising multiple symmetrically installed fixing plates, one side of the fixing plate being fixedly connected to one side of the installation frame, a guide rod being slidably connected inside the fixing plate, an extrusion plate being fixedly connected to one end of two of the guide rods, a threaded rod being rotatably connected to one side of the extrusion plate, a support plate being threadedly connected to the outer wall of the threaded rod, one side of the support plate being fixedly connected to one side of the installation frame, a handle being fixedly connected to the other side of the support plate, and a self-healing component installed inside the installation frame.

[0006] By adopting the above technical solution, the threaded rod rotates when the handle is rotated. Under the precise guidance of the guide rod, the extrusion plate can smoothly and accurately approach the corner of the rigid polyurethane foam board, effectively preventing the rigid polyurethane foam board from warping during use. This avoids heat loss and moisture penetration caused by warping, and improves the problem of warping at the corners of the structure. The gaps created by warping will form thermal bridges, and air convection will accelerate heat exchange. Furthermore, the gaps created by warping will become rainwater penetration channels, allowing rainwater to seep into the board, which will lead to a decrease in the thermal insulation and waterproofing effects of the structure.

[0007] Preferably, a silicone pad is fixedly connected to the other side of the extrusion plate, and the length of the silicone pad is equal to the length of the extrusion plate.

[0008] Preferably, the self-healing component includes a rigid polyurethane foam board, the outer wall of which is installed in the mounting frame, and a connecting pipe is fixedly connected inside the rigid polyurethane foam board. The outer wall of the connecting pipe is uniformly provided with capillary pores, and the outer wall of the connecting pipe is distributed in an S-shape inside the rigid polyurethane foam board.

[0009] Preferably, a waterproof layer is fixedly connected to the outer wall of the rigid polyurethane foam board, and the cross-sectional area of ​​the waterproof layer is equal to the cross-sectional area of ​​the rigid polyurethane foam board.

[0010] Preferably, an insulation layer is fixedly connected to the outer wall of the waterproof layer, and the cross-sectional area of ​​the insulation layer is equal to the cross-sectional area of ​​the waterproof layer.

[0011] Preferably, mounting blocks are symmetrically fixedly connected to the top and bottom of the mounting frame, and mounting holes are provided inside each mounting block.

[0012] Preferably, one end of the connecting pipe is slidably connected to one side of the mounting frame.

[0013] Preferably, the length of the extrusion plate is equal to the length of the insulation layer.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by rotating the handle, the threaded rod rotates accordingly. Under the precise guidance of the guide rod, the extrusion plate can steadily and accurately approach the edge of the rigid polyurethane foam board, effectively preventing the rigid polyurethane foam board from warping during use and avoiding heat loss and moisture penetration caused by warping.

[0015] 2. In this utility model, liquid repair agent is delivered from an external storage tank to a connecting pipe by an external pressure pump. The repair agent can seep out evenly from the capillary pores of the pipe and accurately fill the cracks. There is no need for complicated manual repair operations. Cracks can be repaired in time after they are discovered, effectively preventing the cracks from expanding and causing a decline in thermal insulation and waterproof performance, thus improving the self-maintenance ability and service life of the structure.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-4 This utility model provides an embodiment of a rigid polyurethane foam thermal insulation and waterproof structure, including a mounting frame 1. An anti-warping component is installed on one side of the mounting frame 1. The anti-warping component includes multiple sets of symmetrically installed fixing plates 2. One side of the fixing plate 2 is fixedly connected to one side of the mounting frame 1. A guide rod 201 is slidably connected inside the fixing plate 2. One end of the two guide rods 201 is fixedly connected to an extrusion plate 202. A threaded rod 203 is rotatably connected to one side of the extrusion plate 202. A support plate 204 is threadedly connected to the outer wall of the threaded rod 203. One side of the support plate 204 is fixedly connected to one side of the mounting frame 1. A handle 205 is fixedly connected to the other side of the support plate 204. A self-healing component is installed inside the mounting frame 1.

[0020] Specifically, after the rigid polyurethane foam board 4 is installed into the mounting frame 1, the operator rotates the handle 205, which drives the threaded rod 203 that is rotatably connected to the extrusion plate 202, and pushes the extrusion plate 202 to move towards the rigid polyurethane foam board 4 with the cooperation of the guide rod 201, so as to ensure that the extrusion plate 202 smoothly approaches the corner of the rigid polyurethane foam board 4. When the extrusion plate 202 is tightly fitted to the edges and corners of the rigid polyurethane foam board 4, stop rotating the handle 205. The threaded rod 203 adopts a trapezoidal screw. The self-locking characteristic of the trapezoidal screw can prevent the threaded rod 203 from rotating in the opposite direction, so that the extrusion plate 202 maintains stable pressure and firmly fixes the rigid polyurethane foam board 4. This prevents the edge from warping due to temperature changes or external forces during use, thereby preventing heat loss and moisture penetration from the warped edge gaps and ensuring thermal insulation and waterproof performance.

[0021] Reference Figures 3-4 A silicone pad 3 is fixedly connected to the other side of the extrusion plate 202, and the length of the silicone pad 3 is equal to the length of the extrusion plate 202.

[0022] Specifically, the length of the silicone pad 3 is exactly the same as the length of the extrusion plate 202, ensuring that when the extrusion plate 202 contacts the rigid polyurethane foam board 4 and the insulation layer 6, the silicone pad 3 fully covers the extrusion surface. The silicone pad 3 is soft and elastic. When the extrusion plate 202 applies pressure, the silicone pad 3 undergoes elastic deformation, buffering the rigid pressure of the extrusion plate 202 on the rigid polyurethane foam board 4 and the insulation layer 6, avoiding indentations and damage on the surface of the board, and extending the overall service life of the structure.

[0023] Reference Figures 5-7 The self-healing component includes a rigid polyurethane foam board 4. The outer wall of the rigid polyurethane foam board 4 is installed in the mounting frame 1. A connecting pipe 401 is fixedly connected inside the rigid polyurethane foam board 4. The outer wall of the connecting pipe 401 is uniformly provided with capillary pores 402. The outer wall of the connecting pipe 401 is S-shaped and distributed inside the rigid polyurethane foam board 4.

[0024] A waterproof layer 5 is fixedly connected to the outer wall of the rigid polyurethane foam board 4, and the cross-sectional area of ​​the waterproof layer 5 is equal to the cross-sectional area of ​​the rigid polyurethane foam board 4.

[0025] A thermal insulation layer 6 is fixedly connected to the outer wall of the waterproof layer 5, and the cross-sectional area of ​​the thermal insulation layer 6 is equal to the cross-sectional area of ​​the waterproof layer 5.

[0026] One end of the connecting pipe 401 is slidably connected to one side of the mounting frame 1.

[0027] Specifically, when the rigid polyurethane foam board 4 cracks due to external force or aging, the external pressure pump is connected to one end of the connecting pipe 401. Liquid repair agent is injected into the connecting pipe 401 through the pressure pump. Under pressure, the repair agent flows along the S-shaped connecting pipe 401 and seeps out evenly from the capillary pores 402 evenly opened on the outer wall of the pipe. The S-shaped connecting pipe 401 can increase the contact area between the repair agent and the interior of the rigid polyurethane foam board 4, ensuring that the repair agent quickly and completely penetrates into the crack and fills the crack gap. No cumbersome manual operation is required, which can realize the timely repair of cracks and prevent the cracks from expanding and causing a decrease in thermal insulation and waterproof performance. The cross-sectional area of ​​the waterproof layer 5 is exactly the same as that of the rigid polyurethane foam board 4. It can completely cover the surface of the rigid polyurethane foam board 4, forming a tight waterproof barrier, effectively preventing moisture from penetrating into the interior of the board and protecting the thermal insulation performance of the rigid polyurethane foam board 4. The insulation layer 6, which is fixed to the outer wall of the waterproof layer 5, has the same cross-sectional area as the waterproof layer 5. It is tightly bonded to the waterproof layer 5 and the rigid polyurethane foam board 4 by a pressing process, ensuring that there are no gaps between the layers. The insulation layer 6 reduces heat transfer and energy consumption, and forms an organic whole with the waterproof layer 5 and the rigid polyurethane foam board 4, working together to play a role in waterproofing and insulation.

[0028] Reference Figures 1-2 Mounting blocks 7 are symmetrically fixedly connected to the top and bottom of the mounting frame 1, and mounting holes 701 are opened inside the mounting blocks 7.

[0029] Specifically, the structure can be securely installed on the required wall surface through the mounting hole 701, ensuring the stability and safety of the structure, while also facilitating disassembly and maintenance in the future.

[0030] Reference Figure 3 The length of the extrusion plate 202 is equal to the length of the insulation layer 6.

[0031] Specifically, the extrusion plate 202 can effectively extrude the entire edge of the insulation layer 6 and the rigid polyurethane foam board 4, ensuring the comprehensiveness and uniformity of the anti-warping effect, and further improving the stability and reliability of the structure.

[0032] Working principle: After the rigid polyurethane foam board 4 is installed into the mounting frame 1, the operator rotates the handle 205, which drives the threaded rod 203 to push the extrusion plate 202 towards the rigid polyurethane foam board 4 with the help of the guide rod 201, so that the extrusion plate 202 smoothly approaches its corner position; the silicone pad 3 is exactly the same length as the extrusion plate 202, and fully covers the extrusion surface during extrusion. The silicone pad 3 undergoes elastic deformation to buffer the rigid pressure; when cracks appear in the rigid polyurethane foam board 4, the external pressure pump is connected to one end of the pipe 401 to inject... The liquid repair agent flows along the S-shaped connecting pipe 401 and seeps out evenly from the capillary pores 402 on the outer wall of the pipe; the cross-sectional area of ​​the waterproof layer 5 on the outer wall of the rigid polyurethane foam board 4 is exactly the same as that of the waterproof layer 5, and it completely covers the surface; the cross-sectional area of ​​the insulation layer 6 on the outer wall of the waterproof layer 5 is the same as that of the waterproof layer 5, and it is tightly bonded to the waterproof layer 5 and the rigid polyurethane foam board 4 through a pressing process, with no gaps between the layers; the structure can be installed on the wall through the mounting hole 701, and the extrusion plate 202 extrudes the insulation layer 6 and the entire edge of the rigid polyurethane foam board 4.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
