Abstract
Description
Technical Field
[0001] This utility model relates to the field of building materials technology, specifically to a thermal insulation plywood for building underfloor heating. Background Technology
[0002] Underfloor heating insulation plywood is a type of insulation material used in underfloor heating systems. It is typically composed of multiple layers of materials and has excellent thermal insulation, sound insulation, and moisture-proof properties. Underfloor heating insulation plywood generally consists of two or three layers of materials, the most commonly used of which are EPS (polystyrene) and XPS (extruded polystyrene board). Both of these materials are made from polystyrene, but their manufacturing processes differ.
[0003] An existing Chinese patent (authorization announcement number: CN216007651U) discloses an energy-saving indoor underfloor heating system for high-rise buildings. It includes a heating frame and, from bottom to top, an insulation board, underfloor heating pipes, a heat-conducting plate, and a decorative panel arranged within the heating frame. Connecting meshes are installed on the vertical inner walls on both sides of the heating frame. The insulation board and underfloor heating pipes are located between two connecting meshes, and a connecting structure is provided between the connecting meshes and the underfloor heating pipes for supporting the underfloor heating pipes on the insulation board. This application effectively ensures the integrity of the insulation board structure.
[0004] The existing insulation panels for building underfloor heating require the following installation process: first, the insulation board is installed, then the underfloor heating pipes are installed on the insulation board, then the heat-conducting plate is laid on the underfloor heating pipes, and finally the decorative panel is installed on the heat-conducting plate. However, the existing system requires bending and positioning of the underfloor heating pipes during installation to allow for a wider layout and improve the heating effect. But during the installation process, the existing system requires other devices to assist in limiting the movement of the underfloor heating pipes, making the installation process inconvenient. Utility Model Content
[0005] The purpose of this application is to provide an insulation board for building underfloor heating, which addresses the inconvenience of installing hot water pipes using existing insulation boards for building underfloor heating.
[0006] To achieve the above objectives, this application specifically adopts the following technical solution:
[0007] An insulating plywood for building underfloor heating includes a base layer, on which a hot water pipe is installed, on which a heat-conducting layer is installed, on which a floor is fixedly connected, and an installation structure is provided between the base layer and the heat-conducting layer.
[0008] By adopting the above technical solution, when the device is installed, the base layer is first fixed to the floor slab, and then the hot water pipe is laid on the base layer. During the laying process, the hot water pipe is limited by the installation structure, which makes the hot water pipe better restricted during the installation process. This facilitates the installation of the heat-conducting layer and the floor on the hot water pipe. The installation structure also reduces the shaking and misalignment of the hot water pipe during the installation process, thus enhancing the ease of installation of the device.
[0009] Furthermore, an installation column is fixedly connected to the base layer, a limiting plate is fixedly connected to the installation column, a first limiting plate is fixedly connected to one side of the limiting plate, and a second limiting plate is fixedly connected to the side of the limiting plate away from the first limiting plate. Both the first limiting plate and the second limiting plate are rubber plates.
[0010] By adopting the above technical solution, the hot water pipe is placed on the first and second limiting plates, and then the hot water pipe is pressed down towards the foundation layer, causing the first and second limiting plates to rotate, so that the hot water pipe fits into the mounting column, thereby limiting the upward movement of the hot water pipe and reducing its displacement.
[0011] Furthermore, a limiting block is fixedly connected to the first limiting plate, and a limiting block is fixedly connected to the second limiting plate. The limiting block and the limiting block are adapted to the water pipe.
[0012] By adopting the above technical solution, the limiting block 1 on limiting plate 1 and limiting plate 2 is attached to the top of the hot water pipe to limit the hot water pipe, thereby enhancing the limiting effect when the device is installed on the hot water pipe.
[0013] Furthermore, an installation groove is provided between the mounting column and the limiting plate, and a heat-conducting column is slidably disposed in the installation groove, and the heat-conducting column is fixedly connected to the heat-conducting layer.
[0014] By adopting the above technical solution, the heat-conducting pillars on the heat-conducting layer are inserted into the installation groove, which improves the heat conduction effect of the heat-conducting layer and also limits the position during installation, making it less likely to shift when installing the heat-conducting layer.
[0015] Furthermore, a limiting strip is fixedly connected to the heat-conducting column, and the limiting strip is slidably disposed with respect to the mounting groove.
[0016] By adopting the above technical solution, the heat-conducting column is inserted into the installation groove along the limiting strip, which serves to limit and assist in the installation.
[0017] Furthermore, the limiting plate is hinged to both sides with arc-shaped plates, and the bottom of the heat-conducting layer is fixedly connected with a fixing strip, which is slidably disposed with limiting plate one and limiting plate two.
[0018] By adopting the above technical solution, the hot water pipe at the bend is restricted by the arc plate, which strengthens the contact area between the heat-conducting layer and the hot water pipe and improves the heat conduction.
[0019] Furthermore, a partition is fixedly connected inside the heat-conducting layer. The partition is a polyurethane foam board, and an mounting plate is fixedly connected to the partition. Several mounting rings are fixedly connected to the mounting plate.
[0020] By adopting the above technical solution, during the use of underfloor heating, the hot water in the hot water pipes distributes heat between the heat-conducting layer and the foundation layer. When heat penetrates into the foundation layer, it is blocked by the baffle and remains within the foundation layer, thus reducing heat loss. Furthermore, the mounting plate reduces contact with the floor slab through the mounting ring, further reducing heat loss.
[0021] Furthermore, a heat-conducting strip is fixedly connected to the heat-conducting layer, and a heat-conducting groove is provided on the floor, with the heat-conducting strip and the heat-conducting groove being compatible.
[0022] By adopting the above technical solution, when the heat-conducting layer conducts heat, the heat-conducting strip increases the contact area between the heat-conducting layer and the floor, thereby improving the heat transfer capacity of the heat-conducting layer and allowing the floor to receive more heat.
[0023] In summary, this application includes at least one of the following beneficial effects:
[0024] 1. In this application, when installing hot water pipes, the hot water pipes are fitted onto the mounting column according to the distribution requirements. During the fitting process, the hot water pipes are placed on limiting plate one and limiting plate two, and then the hot water pipes are pressed down onto the base layer, causing limiting plate one and limiting plate two to rotate, so that the hot water pipes are in contact with the mounting column. The limiting block one on limiting plate one and limiting plate two is in contact with the top of the hot water pipes to limit their position. The hot water pipes at the bends are restricted by the arc plate. This reduces the shaking and misalignment of the hot water pipes during installation through the installation structure, enhances the ease of installation of the device, and facilitates both the laying of hot water pipes and the subsequent installation of the heat-conducting layer.
[0025] 2. In this application, during the use of local heating, the hot water in the hot water pipe distributes heat between the heat-conducting layer and the base layer. When the heat penetrates into the base layer, it is blocked by the partition and remains in the base layer, thereby reducing heat loss. The mounting plate reduces the contact with the floor slab through the mounting ring, further reducing heat loss. Attached Figure Description

Detailed Implementation
[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0035] This application discloses an insulating plywood for building underfloor heating.
[0036] Reference Figure 1 An insulating plywood for building underfloor heating includes a base layer 1, a hot water pipe 2 installed on the base layer 1, a heat-conducting layer 3 installed on the hot water pipe 2, a floor 4 fixedly connected to the heat-conducting layer 3, and an installation structure between the base layer 1 and the heat-conducting layer 3.
[0037] When the device is installed, the base layer 1 is first fixed to the floor slab, and then the hot water pipe 2 is laid on the base layer 1. During the laying process, the hot water pipe 2 is limited by the installation structure, so that the hot water pipe 2 is better limited during the installation process. This makes it easier to install the heat-conducting layer 3 and the floor 4 on the hot water pipe 2. The installation structure reduces the shaking and misalignment of the hot water pipe 2 during the installation process, and enhances the ease of installation of the device.
[0038] Reference Figure 3 and Figure 4 , Figure 5 , Figure 6A mounting column 9 is fixedly connected to the base layer 1. A limiting plate 11 is fixedly connected to the mounting column 9. A limiting plate 12 is fixedly connected to one side of the limiting plate 11, and a limiting plate 13 is fixedly connected to the side of the limiting plate 11 away from the limiting plate 12. Both the limiting plate 12 and the limiting plate 13 are rubber plates. A limiting block 16 is fixedly connected to the limiting plate 12, and a limiting block 17 is fixedly connected to the limiting plate 13. The limiting blocks 16 and 17 are compatible with water pipes.
[0039] An installation groove is provided between the mounting column 9 and the limiting plate 11. A heat-conducting column 10 is slidably disposed in the installation groove and is fixedly connected to the heat-conducting layer 3. A limiting strip 14 is fixedly connected to the heat-conducting column 10 and is slidably disposed with respect to the installation groove. Arc-shaped plates 18 are hinged to both sides of the limiting plate 11. A fixing strip 15 is fixedly connected to the bottom of the heat-conducting layer 3 and is slidably disposed with the limiting plate 12 and the limiting plate 13.
[0040] When installing hot water pipe 2, hot water pipe 2 is fitted onto the mounting column 9 according to the distribution requirements. During the fitting process, hot water pipe 2 is placed on limiting plate 12 and limiting plate 23, and then hot water pipe 2 is pressed down onto the base layer 1, causing limiting plate 12 and limiting plate 23 to rotate, so that hot water pipe 2 is in contact with the mounting column 9, and limiting block 16 on limiting plate 12 and limiting plate 23 is in contact with the upper part of hot water pipe 2 to limit hot water pipe 2. At the bend, hot water pipe 2 is limited by arc plate 18. This allows the device to limit hot water pipe 2 during the installation process, which not only facilitates the laying of hot water pipe 2, but also facilitates the subsequent installation of heat-conducting layer 3.
[0041] When installing the heat-conducting layer 3, the heat-conducting column 10 on the heat-conducting layer 3 is inserted into the installation groove along the limiting strip 14. At the same time, the fixing strip 15 on the heat-conducting layer 3 is also moved between the limiting plate 12 and the limiting plate 23 and fits against the hot water pipe 2. This increases the area of the heat-conducting layer 3 that receives heat from the hot water pipe 2, improves the heat conduction effect of the heat-conducting layer 3, and also limits the installation, making it less likely to shift when installing the heat-conducting layer 3.
[0042] Reference Figure 1 and Figure 2 A partition 5 is fixedly connected inside the heat-conducting layer 3. The partition 5 is a polyurethane foam board. An mounting plate 6 is fixedly connected to the partition 5. Several mounting rings 7 are fixedly connected to the mounting plate 6.
[0043] During the use of underfloor heating, the hot water in the hot water pipe 2 distributes heat to the heat-conducting layer 3 and the base layer 1. When the heat penetrates into the base layer 1, it is blocked by the partition 5 and remains in the base layer 1, thereby reducing heat loss. The mounting plate 6 reduces contact with the floor slab through the mounting ring 7, further reducing heat loss.
[0044] Reference Figure 3 A heat-conducting strip 8 is fixedly connected to the heat-conducting layer 3, and a heat-conducting groove is provided on the floor 4. The heat-conducting strip 8 is adapted to the heat-conducting groove.
[0045] When the heat-conducting layer 3 conducts heat, the heat-conducting strip 8 increases the contact area between the heat-conducting layer 3 and the floor 4, thereby increasing the heat transfer of the heat-conducting layer 3 and allowing the floor 4 to receive more heat.
[0046] Working principle: When the device is installed, the base layer 1 is first fixed to the floor slab. When installing the hot water pipe 2, the hot water pipe 2 is sleeved on the installation column 9 according to the distribution requirements. During the sleeved installation process, the hot water pipe 2 is placed on the limiting plate 12 and the limiting plate 23, and then the hot water pipe 2 is pressed down on the base layer 1, so that the limiting plate 12 and the limiting plate 23 rotate, so that the hot water pipe 2 is in contact with the installation column 9, and the limiting block 16 on the limiting plate 12 and the limiting plate 23 is in contact with the upper part of the hot water pipe 2, thus limiting the hot water pipe 2. The hot water pipe 2 at the bend is limited by the arc plate 18. This allows the device to limit the hot water pipe 2 during the installation process, which not only facilitates the laying of the hot water pipe 2, but also facilitates the subsequent installation of the heat-conducting layer 3.
[0047] When installing the heat-conducting layer 3, the heat-conducting column 10 on the heat-conducting layer 3 is inserted into the installation groove along the limiting strip 14. At the same time, the fixing strip 15 on the heat-conducting layer 3 is also moved between the limiting plate 12 and the limiting plate 2 13 and fits against the hot water pipe 2. This increases the area of the heat-conducting layer 3 that receives heat from the hot water pipe 2 and improves the heat conduction effect of the heat-conducting layer 3.
[0048] During the use of underfloor heating, the hot water in the hot water pipe 2 distributes heat to the heat-conducting layer 3 and the base layer 1. When the heat penetrates into the base layer 1, it is blocked by the partition 5 and remains in the base layer 1, thereby reducing heat loss. The mounting plate 6 reduces contact with the floor slab through the mounting ring 7, further reducing heat loss.
