Description

Technical Field

[0001] This utility model relates to the field of underfloor heating board installation technology, specifically to a connection device for underfloor heating boards and 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, significantly increasing maintenance and time costs. Utility Model Content

[0004] In view of this, the present invention provides a connecting device and a floor heating board to solve the problem that the installation of floor heating boards requires the use of fixing materials such as glue and nails, and that subsequent maintenance and replacement are difficult.

[0005] Firstly, this utility model provides a floor heating panel connection device, comprising:

[0006] Two first connectors are fixedly connected to each other. Each first connector includes an abutting part and a snap-fit ​​part. The abutting part is arranged parallel to the plane of the underfloor heating board. The snap-fit ​​part is formed by extending from the first end of the abutting part in a direction perpendicular to the surface of the underfloor heating board.

[0007] The second ends of the two abutting portions are fixedly connected to each other along the width direction of the floor heating board and are coplanar;

[0022] Beneficial effects

[0023] The floor heating panel connecting device provided by this utility model includes two first connecting members. Each first connecting member includes an abutting part and a snap-fit ​​part. The abutting part is arranged parallel to the plane of the floor heating panel. The snap-fit ​​part is formed by extending from the first end of the abutting part in a direction perpendicular to the plane of the floor heating panel. The second ends of the two abutting parts are fixedly connected to each other along the width direction of the floor heating panel and are coplanar. The floor heating panel has a receiving cavity inside and a snap-fit ​​hole on one side of the panel. The floor heating panel includes at least two parallel main body members. When the two main body members are connected along the width direction, the two first connecting members are respectively placed in the corresponding receiving cavities.

[0024] The floor heating panel connection device provided by this utility model, through the abutment part and snap-fit ​​part structure of the first connector, eliminates the need for fixing materials such as glue and nails. Simply place it in the floor heating panel receiving cavity and snap it into the snap-fit ​​hole to achieve floor heating panel connection, simplifying the installation process and shortening the installation cycle.

[0044] 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.

[0045] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0046] According to an embodiment of the present invention, in one aspect, a floor heating panel connection device is provided, comprising:

[0047] Two first connectors 1, each first connector 1 includes an abutting part 11 and a snap-fit ​​part 12. The abutting part 11 is arranged parallel to the plane of the underfloor heating board. The snap-fit ​​part 12 extends from the first end of the abutting part 11 in a direction perpendicular to the plane of the underfloor heating board.

[0048] The second ends of the two abutting parts 11 are fixedly connected to each other along the width direction of the floor heating board and are coplanar;

[0049] The floor heating panel has an internal cavity and a snap-fit ​​hole 21 on one side of the panel.

[0050] The underfloor heating panel includes at least two parallel main body parts 3. When the two main body parts 3 are connected along the width direction, the two first connecting parts 1 are respectively placed in the corresponding receiving cavities. The abutting part 11 abuts against the inner wall of the receiving cavity near the snap-fit ​​part 12, and the snap-fit ​​part 12 snaps into the snap-fit ​​hole 21.

[0051] It should be noted that the receiving cavity is a specially designed spatial structure inside the underfloor heating panel. Its shape and size are adapted to the first connector 1, providing an installation position for the first connector 1. When the underfloor heating panels are connected, the first connector 1 is embedded in the receiving cavity, so that the abutting part 11 can stably abut against the inner wall of the receiving cavity near the snap-fit ​​hole 21, thereby ensuring that the snap-fit ​​part 12 can smoothly snap into the snap-fit ​​hole 21, realizing a stable connection between the two underfloor heating panels. At the same time, the existence of the receiving cavity also ensures the integrity and stability of the overall structure of the underfloor heating panel.

[0052] The floor heating panel connection device provided by this utility model, through the abutment part 11 and the snap-fit ​​part 12 structure of the first connector 1, eliminates the need for fixing materials such as glue and nails. It can be placed in the floor heating panel receiving cavity and snapped into the snap-fit ​​hole 21 to realize the connection of the floor heating panel, which simplifies the installation process and shortens the installation cycle. In the later maintenance and replacement, it is easy to disassemble, avoids damage to the floor and floor heating pipes, and reduces maintenance costs and time costs.

[0053] Furthermore, the snap-fit ​​part 12 includes:

[0054] The guide slope is set at an acute angle to the plane where the hole wall of the snap-fit ​​hole 21 is located, and the guide slope is suitable for guiding the snap-fit ​​part 12 to snap into the snap-fit ​​hole 21;

[0055] The positioning plane is set parallel to the plane containing the hole wall of the snap-fit ​​hole 21, and intersects with the guide slope to form a guide structure.

[0056] It should be noted that the snap-fit ​​part 12 is provided with a guide slope and a positioning plane. The guide slope cooperates with the plane where the snap-fit ​​hole 21 is located. When connecting the floor heating board, it can automatically guide the snap-fit ​​part 12 to quickly snap into the snap-fit ​​hole 21, reducing the difficulty of installation and improving installation efficiency. The positioning plane is set parallel to the wall of the snap-fit ​​hole 21. When the snap-fit ​​part 12 is fully snapped in, the positioning plane and the wall of the snap-fit ​​hole 21 are tightly fitted, which can effectively limit the relative displacement between the floor heating boards, ensure the stability of the connection, and prevent the floor heating boards from loosening and affecting the use effect.

[0057] It should be noted that in this embodiment, the snap-fit ​​hole 21 is a through hole, which allows the snap-fit ​​part 12 of the first connector 1 to pass smoothly through the snap-fit ​​hole 21 from one side of the receiving cavity and be snapped in place, making the installation process smoother. Construction personnel can also observe the snap-fit ​​from the outer side of the floor heating board. During later maintenance or replacement of the floor heating board, it is also convenient to apply force to the snap-fit ​​part 12 from the other side of the snap-fit ​​hole 21, achieving quick disassembly and reducing the risk of damage to the floor heating board and surrounding structures. Of course, in other embodiments, the snap-fit ​​hole 21 can also be a countersunk hole where the receiving cavity is recessed into the surface of the floor heating board.

[0058] Furthermore, the snap-fit ​​hole 21 is provided on the surface of the underfloor heating panel near the ground.

[0059] It should be noted that the snap-fit ​​hole 21 is located on the surface of the underfloor heating board near the ground, which can effectively prevent direct impact on the snap-fit ​​structure caused by external forces such as stepping or furniture placement during daily use, reducing the risk of the snap-fit ​​part 12 loosening or being damaged; at the same time, this setting allows the snap-fit ​​process to be carried out in a concealed position near the ground, which does not affect the flatness and aesthetics of the upper surface of the underfloor heating board, nor does it interfere with the laying of the floor decoration layer.

[0060] Furthermore, it also includes:

[0061] Limiting member 13 is disposed on the first connecting member 1;

[0062] The side of the floor heating panel with the snap-fit ​​hole 21 is also provided with a limit hole 22;

[0063] The limiting member 13 is adapted to abut against the wall of the limiting hole 22 to restrict the relative movement of the two floor heating panels in the width direction.

[0064] It is easy to understand that a limiting member 13 is provided on the first connecting member 1, and a limiting hole 22 is provided on the corresponding surface of the underfloor heating panel. The relative movement of the two underfloor heating panels in the width direction can be effectively restricted by the abutment between the limiting member 13 and the wall of the limiting hole 22. This not only enhances the overall stability of the underfloor heating panels after splicing, but also avoids misalignment and separation of the underfloor heating panels due to factors such as thermal expansion and contraction, external force, and trampling.

[0065] Specifically, in this embodiment, the limiting hole 22 is located at the joint of the two floor heating panels. That is, the limiting hole 22 is composed of parts located on a main body 3, and the cross-sectional area of ​​the limiting hole 22 and the limiting member 13 is larger than the cross-sectional area of ​​the snap-fit ​​hole 21 and the snap-fit ​​part 12. During installation, the limiting member 13 can simultaneously and tightly engage with the limiting hole 22 portions on both floor heating panels, creating a stronger constraint effect in the width direction and enhancing the connection strength at the joint of the floor heating panels. Furthermore, this arrangement effectively avoids the structural weakening problem that might occur if a complete limiting hole 22 is provided on a single floor heating panel, ensuring the overall structural strength of the floor heating panel. Of course, in an optional embodiment, limiting holes 22 can also be provided separately on each floor heating panel.

[0066] Furthermore, the limiting member 13 is a rectangular limiting protrusion that is perpendicular to the surface of the floor heating board, and the height direction of the rectangular limiting protrusion is consistent with the extension direction of the snap-fit ​​part 12.

[0067] In a straightforward manner, the limiting component 13 employs a rectangular limiting protrusion perpendicular to the surface of the underfloor heating panel, with its height direction aligned with the extension direction of the snap-fit ​​portion 12. The rectangular shape ensures that each surface provides effective limiting force when it abuts against the wall of the limiting hole 22, restricting the horizontal movement of the underfloor heating panel from multiple directions and enhancing connection stability. The vertical arrangement ensures full contact between the limiting protrusion and the limiting hole 22, resulting in uniform force distribution and preventing localized stress concentration. Alignment with the extension direction of the snap-fit ​​portion 12 makes the entire connection device more accurately positioned and easier to operate during installation. While achieving reliable limiting, it also further simplifies the installation process and improves construction efficiency.

[0068] In an optional embodiment, the limiting member 13 may also be a T-shaped limiting block. The T-shaped structure can provide a larger limiting area in the width direction, enhancing the limiting effect. Furthermore, the horizontal portion of the T-shaped limiting block can extend through the limiting hole 22 to the surface of the underfloor heating panel, thereby forming a height-direction limit to prevent the underfloor heating panel from separating or tilting under forces in the height direction. Here, the specific shape of the limiting member 13 is not limited; in other embodiments, the limiting member 13 may also be circular, polygonal, or irregular in shape.

[0069] Furthermore, the underfloor heating panel includes two parallel panels, and the height of the rectangular limiting protrusion is less than or equal to the thickness of the main body 3.

[0070] It should be noted that in this embodiment, the underfloor heating board is a hollow structure consisting of two parallel panels. This not only reduces the overall weight of the underfloor heating board, making it easier to transport and install, but also optimizes the air circulation inside the underfloor heating board through the hollow space, which helps to conduct heat more evenly. At the same time, it saves raw materials and reduces production costs.

[0071] It should be noted that the height of the rectangular limiting protrusion is less than or equal to the thickness of the main body 3, that is, the height of the rectangular limiting protrusion is less than or equal to the height of the plate. This ensures that after the limiting protrusion is embedded in the limiting hole 22, it will not protrude from the surface of the floor heating board, thus ensuring the flatness of the upper surface of the floor heating board.

[0072] Furthermore, it also includes:

[0073] The support member 14 is disposed on the side of the abutment portion 11 away from the snap-fit ​​portion 12, and the support member 14 is adapted to abut against the inner wall of the receiving cavity.

[0074] It should be noted that the support member 14 is located on the side of the abutment portion 11 away from the snap-fit ​​portion 12, and is used to enhance the support effect of the first connector 1 within the cavity of the underfloor heating panel. When the underfloor heating panel is subjected to external forces such as being stepped on or squeezed by furniture, the support member 14 can abut against the inner wall of the cavity to share the pressure borne by the underfloor heating panel, thereby preventing the first connector 1 from deforming or being damaged due to uneven force. During use, the support member 14 can further restrict the displacement of the first connector 1, and together with the snap-fit ​​portion 12 and the limiting member 13, ensure the stability of the connection between the underfloor heating panels from multiple dimensions, extend the service life of the underfloor heating system, and reduce maintenance costs and repair frequency caused by loose connectors. The support member 14 and the first connector 1 are integrally formed and have a hollow structure. The first connector 1 is located on the side of the support member 14 near the underfloor heating panel where the snap-fit ​​hole 21 and the limiting hole 22 are provided.

[0075] Here, a method for using a floor heating panel connection device is provided. First, two first connectors 1 are respectively placed into the receiving cavities of the corresponding floor heating panels, so that the abutting part 11 abuts against the inner wall of the receiving cavity near the snap-fit ​​hole 21. Then, the floor heating panels with snap-fit ​​holes 21 and limiting holes 22 are spliced ​​together on the side closest to the ground. During the splicing process, the guide slope of the snap-fit ​​part 12 is used to guide the snap-fit ​​part 12 to smoothly snap into the snap-fit ​​hole 21. At the same time, the limiting part 13 is aligned with the limiting hole 22 and abuts against each other to limit horizontal displacement. If a support part 14 is provided, it is ensured that the support part 14 abuts against the inner wall of the receiving cavity during installation to help the first connector 1 be firmly positioned, thus completing the quick and firm connection of the two floor heating panels.

[0076] According to an embodiment of the present invention, another aspect provides a floor heating board, comprising:

[0077] At least two main components 3;

[0078] The floor heating board connecting device described in any one of the above descriptions is suitable for connecting two adjacent main body parts 3 along the width direction.

[0079] Furthermore, it also includes:

[0080] The second connector 4 and the third connector 5 are respectively disposed on the two opposite ends of the main body 3 along the length direction. The second connector 4 protrudes outward from the main body 3 to form a first fixing part 41. The first fixing part is recessed in at least one side along the height direction of the main body 3 to form a second fixing part 42. The third connector 5 is recessed in the main body 3 to form a third fixing part 51. The third fixing part 51 protrudes outward from at least one side along the height direction of the main body 3 to form a fourth fixing part 52.

[0081] When at least two main body parts 3 are connected along their length, the first fixing part 41 and the third fixing part 51 are engaged, the second fixing part 42 and the fourth fixing part 52 are engaged, and the second fixing part 42 and the fourth fixing part 52 form a limiting structure along the length of the main body part 3 to realize the connection between the second connecting part 4 and the third connecting part 5.

[0082] The underfloor heating panel provided in this embodiment connects the main body 3 via second connectors 4 and third connectors 5 at both ends. This connection is achieved through the interlocking of the first fixing part 41 with the fourth fixing part 52, and the second fixing part 42 with the fourth fixing part 52. After connection, the second fixing part 42 and the fourth fixing part 52 form a limiting structure along the length of the main body 3, preventing potential detachment of the two main body parts 3 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.

[0083] Furthermore, the second connector 4 protrudes outward from the main body 3 to form an arc-shaped first fixing part 41, and the third connector 5 is recessed inward to form an arc-shaped third fixing part 51. The arc-shaped first fixing part 41 is adapted to abut against the arc-shaped third fixing part 51.

[0084] It should be noted that by using the method of mutual abutment between the first curved fixing part 41 and the third curved fixing part 51, 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.

[0085] Furthermore, the second fixing part 42 has at least one first limiting inclined surface that forms an acute angle with the length direction of the main body 3, and the fourth fixing part 52 has at least one second limiting inclined surface that forms an acute angle with the length direction of the main body 3. The first limiting inclined surface and the second limiting inclined surface are fitted together when the second fixing part 42 and the fourth fixing part 52 are fastened together to form a limiting structure.

[0086] It should be noted that, in conjunction with Figure 5 and Figure 6 It can be seen that both the second fixing part 42 and the fourth fixing part 52 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 3, the highest point of the second fixing part 42 and the fourth fixing part 52, i.e., an acute angle of the right triangle, forms a limiting force in that direction. Furthermore, both the second fixing part 42 and the fourth fixing part 52 may also have two limiting inclined surfaces.

[0087] Furthermore, both the second fixing part 42 and the fourth fixing part 52 are one unit, and are provided on the side of the main body 3 near the ground.

[0088] It should be noted that placing the second fixing part 42 and the fourth fixing part 52 on the side of the main body 3 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 42 and the fourth fixing part 52 can also be two separate units, located at opposite ends of the main body 3 in the height direction. In this case, greater external force is required to connect them, but the connection strength is also greater.

[0089] Furthermore, the main body 3 has at least one channel 31 inside, suitable for placing the underfloor heating pipe.

[0090] 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 31 within the main body component 3, with the channel 31 and main body component 3 integrally formed. On one hand, the underfloor heating pipes are fully enclosed and protected by the main body component 3, 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 3 allows heat to be directly transferred to the surrounding area through the main body component 3, 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.

[0091] Specifically, in this embodiment, a floor heating panel has three channels 31 inside, suitable for placing floor heating pipes. In other embodiments, an appropriate number of channels 31 can be set according to the actual size of the floor heating panel and the heating needs, such as one, two, or more.

[0092] Furthermore, the cross-section of channel 31 is circular or elliptical.

[0093] It should be noted that the cross-section of channel 31 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 31 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.

[0094] Furthermore, the channel 31 is positioned perpendicular to the length direction of the main body 3.

[0095] As easily understood, the channel 31 is positioned perpendicular to the length of the main component 3, 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 3, increasing the heat exchange area and thus improving heat transfer efficiency and accelerating indoor heating.

[0096] It should be noted that the channels 31 inside the underfloor heating panels located at the edges need to be equipped with elbows for bending the underfloor heating pipes. This allows the underfloor heating pipes to flexibly change their direction, conforming 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.

[0097] Furthermore, the main body 3 is a metal main body 3.

[0098] 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.

[0099] In one optional embodiment, a floor heating board with a composite material main component 3 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 3 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.

[0100] Furthermore, the main body 3 is an aluminum alloy main body 3.

[0101] 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 component 3 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 component 3, thereby reducing maintenance costs.

[0102] 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.
