Description

Technical Field

[0001] This utility model relates to the field of underfloor heating board installation technology, specifically to an underfloor heating board. Background Technology

[0002] Dry underfloor heating is an innovative, thin-film underfloor heating system that uses prefabricated grooved insulation modules laid dry, eliminating the need for cement backfilling and significantly simplifying the construction process. This system uses a heat equalization layer as a floor radiator, uniformly heating the floor with a low-temperature heat medium. Through a combination of radiation and convection heating, it quickly achieves comfortable indoor heating.

[0003] Compared to traditional underfloor heating, dry underfloor heating is more suitable for flooring installation because it eliminates the need for cement backfilling. It effectively improves heat transfer efficiency and shortens heating time. However, the installation of traditional dry underfloor heating panels has significant drawbacks. The installation process is cumbersome and complex, requiring a large amount of glue, nails, and other fixing materials. This not only prolongs the installation period and reduces construction efficiency but may also affect indoor air quality due to glue evaporation. Furthermore, disassembly is difficult during later maintenance or replacement of the heating panels, easily damaging the flooring and heating pipes, increasing maintenance costs and time. Utility Model Content

[0004] In view of this, the present invention provides a floor heating board to solve the problem that the existing technology requires the use of glue, nails and other fixing materials when installing floor heating boards, and that subsequent maintenance and replacement are difficult.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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, 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.

[0026] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0027] According to an embodiment of the present invention, a floor heating board is provided, comprising:

[0028] Main component 1;

[0029] The first connector 2 and the second connector 3 are respectively disposed on the two end faces opposite to each other in the length direction of the main body 1. The first connector 2 protrudes outward from the main body 1 to form a first fixing part 21. The first fixing part 21 is recessed in at least one side along the height direction of the main body 1 to form a second fixing part 22. The second connector 3 is recessed in the main body 1 to form a third fixing part 31. The third fixing part 31 protrudes outward from at least one side along the height direction of the main body 1 to form a fourth fixing part 32.

[0030] When at least two main body parts 1 are connected along their length, the first fixing part 21 and the third fixing part 31 are engaged, the second fixing part 22 and the fourth fixing part 32 are engaged, and the second fixing part 22 and the fourth fixing part 32 form a limiting structure along the length of the main body part 1 to realize the connection between the first connecting part 2 and the second connecting part 3.

[0031] It should be noted that the main component 1 adopts an abutting splicing method along the width direction, that is, the sides of adjacent underfloor heating panels directly abut against each other. This splicing method ensures that the underfloor heating panels fit tightly together in the width direction, forming a flat and continuous laying surface, ensuring uniform heat transfer, and avoiding problems such as heat loss or uneven local heating due to gaps. At the same time, the abutting splicing operation is simple and does not require additional complex connection structures. While reducing installation steps and construction difficulty, it also facilitates the later inspection, maintenance, and replacement of individual underfloor heating panels.

[0032] The underfloor heating panel provided in this embodiment connects the main body 1 via first connectors 2 and second connectors 3 at both ends. This connection is achieved through the interlocking of first fixing part 21 and third fixing part 31, and second fixing part 22 and fourth fixing part 32. After connection, the second fixing part 22 and fourth fixing part 32 form a limiting structure along the length of the main body 1, preventing potential detachment of the two main body parts 1 in that direction. During installation, no glue, nails, or other fixing materials are required, simplifying the installation process, shortening the installation cycle, and improving construction efficiency. Later maintenance or replacement of the underfloor heating panel is convenient, avoiding damage to the floor and underfloor heating pipes, effectively reducing maintenance and time costs.

[0033] Furthermore, the first connector 2 protrudes outward from the main body 1 to form an arc-shaped first fixing part 21, and the second connector 3 is recessed inward to form an arc-shaped third fixing part 31. The arc-shaped first fixing part 21 is adapted to abut against the arc-shaped third fixing part 31.

[0034] It should be noted that by using the method of mutual abutment between the first curved fixing part 21 and the third curved fixing part 31, a tighter fit can be formed through the curved surface structure. Compared with the flat abutment, the contact area between the curved surfaces is larger, which enhances the connection stability and makes it less prone to loosening or misalignment due to external forces during use. At the same time, the curved surface design makes it easier to align during installation, reducing the difficulty of installation operations and improving installation efficiency. In addition, the curved surface structure can also buffer external forces to a certain extent, reducing damage to the connection of the underfloor heating board caused by collisions and other situations, and extending its service life.

[0035] Furthermore, the second fixing part 22 has at least one first limiting inclined surface that forms an acute angle with the length direction of the main body 1, and the fourth fixing part 32 has at least one second limiting inclined surface that forms an acute angle with the length direction of the main body 1. The first limiting inclined surface and the second limiting inclined surface are fitted together when the second fixing part 22 and the fourth fixing part 32 are fastened together to form a limiting structure.

[0036] It should be noted that, in conjunction with Figure 2 and Figure 3 It can be seen that both the second fixing part 22 and the fourth fixing part 32 are formed obliquely upwards, close to a right triangle, with one right-angled side located on the ground. The hypotenuse serves as the first limiting inclined surface and the second limiting inclined surface. Thus, when subjected to a tensile force along the length of the main body 1, the highest point of the second fixing part 22 and the fourth fixing part 32, i.e., an acute angle of the right triangle, forms a limiting force in that direction. Furthermore, both the second fixing part 22 and the fourth fixing part 32 may also have two limiting inclined surfaces.

[0037] Furthermore, both the second fixing part 22 and the fourth fixing part 32 are one unit, which is provided on the side of the main body 1 near the ground.

[0038] It should be noted that placing the second fixing part 22 and the fourth fixing part 32 on the side of the main body 1 closest to the ground serves several purposes. First, it ensures a more reasonable stress distribution during the connection of the underfloor heating panels. Utilizing gravity and ground support further enhances the stability of the interlocking connection, reducing the risk of loosening due to ground vibrations or foot traffic. Second, during installation, operators can stand on the already laid underfloor heating panels and perform the interlocking operation from below, eliminating the need for frequent panel flipping, reducing installation difficulty, and improving construction convenience and efficiency. Finally, placing the critical connection points closer to the ground avoids damage to the connection structure caused by external forces above the ground, such as foot traffic or furniture pressure, effectively protecting the connecting components, extending the overall service life of the underfloor heating panels, and facilitating quick location and handling of connection issues during later maintenance and repairs. Of course, the second fixing part 22 and the fourth fixing part 32 can also be two separate units, located at opposite ends of the main body 1 in the height direction. In this case, a greater external force is required to connect them, but the connection strength is also greater.

[0039] Furthermore, the main body 1 has at least one channel 4 inside, suitable for placing the underfloor heating pipe.

[0040] It should be noted that existing underfloor heating pipes are installed at the bottom of the underfloor heating slab, making them susceptible to damage and deformation due to uneven ground, external pressure, and other factors. Furthermore, heat must first be transferred to the underfloor heating slab before dissipating into the room, resulting in low heat transfer efficiency. Additionally, separate installation of the underfloor heating slab and pipes increases construction steps and time costs. This device integrates the underfloor heating pipe channel 4 within the main body component 1, with the channel 4 and main body component 1 being integrally formed. On one hand, the underfloor heating pipes are fully enclosed and protected by the main body component 1, reducing the risk of damage from external factors and improving system stability. On the other hand, the tight fit between the underfloor heating pipes and the main body component 1 allows heat to be directly transferred to the surrounding area through the main body component 1, reducing heat loss and improving heat transfer efficiency and heating effect. Moreover, this integrated design simplifies the installation process, eliminating the need for separate installation of the underfloor heating pipes, reducing construction steps, shortening the construction period, and lowering labor costs.

[0041] Specifically, in this embodiment, a floor heating panel has three channels 4 inside, suitable for placing floor heating pipes. In other embodiments, the number of channels 4 can be set according to the actual size of the floor heating panel and the heating needs, such as one, two or more.

[0042] Furthermore, the cross-section of channel 4 is circular or elliptical.

[0043] It should be noted that the cross-section of channel 4 is designed to be circular or elliptical, which can fit the outer contour of the underfloor heating pipe, ensuring that the underfloor heating pipe fits tightly against the inner wall of channel 4 after installation, reducing gap loss during heat transfer and improving heat conduction efficiency; the circular and elliptical structures distribute the force evenly, effectively dispersing the pressure when bearing pressure from the underfloor heating board and the ground, preventing the underfloor heating pipe from deforming or breaking due to excessive local stress, and extending the service life of the underfloor heating pipe.

[0044] Furthermore, channel 4 is positioned perpendicular to the length direction of the main body 1.

[0045] As easily understood, the channel 4 is positioned perpendicular to the length of the main component 1, allowing the underfloor heating pipes to be laid out in a horizontal arrangement. This promotes the even horizontal diffusion of heat throughout the room, preventing uneven heat distribution along the length of the underfloor heating board and effectively improving the overall heating balance. Simultaneously, this vertical arrangement extends the contact path between the underfloor heating pipes and the main component 1, increasing the heat exchange area and thus improving heat transfer efficiency and accelerating indoor heating.

[0046] It should be noted that the channel 4 inside the underfloor heating slab located at the edge needs to be equipped with elbows for bending the underfloor heating pipes. This allows the underfloor heating pipes to flexibly change direction and be laid to conform to the contours of the room's edges, avoiding heating blind spots and ensuring uniform heating throughout the room. The presence of elbows also reduces stress concentration at bends in the underfloor heating pipes, preventing deformation and breakage due to excessive bending, effectively protecting the pipes and extending their service life.

[0047] Furthermore, the main body 1 is a metal main body.

[0048] It is easy to understand that metal has excellent thermal conductivity, which can quickly absorb the heat transferred by the underfloor heating pipes and quickly and evenly distribute the heat to the indoor space, improving heating efficiency and shortening the indoor heating time; it has high strength and good toughness, and is not easily deformed or damaged. During long-term use, it can effectively resist external forces such as ground pressure and people stepping on it.

[0049] In one optional embodiment, a floor heating board with a composite material main component 1 can be used, which combines polystyrene foam with excellent thermal insulation properties with a thermally conductive aluminum plate, taking into account both thermal insulation and thermal conductivity functions. This reduces downward heat loss and efficiently transfers heat, improving the overall performance of the floor heating system. In another optional embodiment, a floor heating board with a stone main component 1 can also be used, such as natural marble or artificial stone. These materials have a beautiful texture, good thermal stability, and can enhance the interior decoration level. In addition, stone is sturdy and durable and can withstand greater pressure.

[0050] Furthermore, the main body 1 is an aluminum alloy main body.

[0051] It should be noted that aluminum alloy has excellent thermal conductivity, which can quickly absorb heat from the underfloor heating pipes and evenly diffuse it, thereby increasing the indoor temperature rise rate and reducing heat loss, thus improving heating efficiency and energy saving. The aluminum alloy main body has excellent corrosion resistance, is not prone to rusting or oxidation in humid environments, has a long service life, and can reduce the need for repair and replacement due to damage to the main body, thereby reducing maintenance costs.

[0052] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
