Description

Technical Field

[0001] The present application relates to the field of floor heating. Background Art

[0002] Floor heating, short for radiant floor heating, uses the entire floor as a radiator. Heat is evenly heated by the heat medium in the floor's radiant layer, providing comfortable heating to the interior through radiation and convection. Floor heating systems are categorized by the heat transfer medium: water-based and electric.

[0003] Water floor heating refers to a heating method that heats water to a certain temperature, transports it to a water pipe heat dissipation network under the floor, and achieves heating purposes by generating heat through the floor.

[0004] Electric floor heating uses a translucent polyester film that generates heat when powered. It's made by processing a special conductive ink and a metal current-carrying strip, then hot-pressing it between insulating polyester films. The carbon-based ink acts as a heating element, radiating heat into the space and providing warmth.

[0005] However, both traditional water and electric floor heating systems suffer from slow heat transfer rates and long startup times. Water floor heating systems require a water temperature of 50-60°C to provide users with warmth, but heating low-temperature water to 50-60°C in cold weather consumes a significant amount of energy. Furthermore, the high heat loss rate of 50-60°C water in cold weather further increases the energy consumption of floor heating systems. Furthermore, the water temperature in floor heating pipes remains at 50-60°C for extended periods, making it very susceptible to scaling. Traditional electric floor heating systems, due to structural flaws, also suffer from slow heat transfer rates and high energy consumption.

[0006] Floor heating systems can be divided into dry floor heating and wet floor heating according to different paving structures.

[0007] Dry floor heating, also known as ultra-thin floor heating, is named so because it requires no backfill compared to conventional floor heating. It also uses less backfill, reducing the floor height required compared to conventional floor heating.

[0008] However, traditional dry floor heating is more expensive than wet floor heating and cannot be installed under floor coverings like tiles and marble, as these materials must be secured with cement during installation. Dry floor heating also lacks a pebble backfill layer, making the heating coils susceptible to damage, reducing their lifespan and potentially causing maintenance issues like leaks.

[0009] Wet floor heating is the most mature installation method for water-based floor heating and is also widely used in electric floor heating. Relatively inexpensive, wet floor heating is the dominant method in the domestic floor heating market. Wet floor heating involves encasing the floor heating pipes in concrete, then laying flooring, tiles, and other flooring materials on top of the concrete layer. This concrete layer not only protects and secures the water heating pipes but also serves as the primary channel for heat transfer. The concrete layer evenly distributes heat, reducing the risk of overheating or overcooling.

[0010] However, wet floor heating requires a concrete layer of sand and gravel, resulting in a heavy average weight, placing approximately eight times more load on the building than radiators. Wet floor heating begins with laying insulation on a concrete surface, followed by piping. Finally, pebble-cement is poured to level the surface, followed by a floor covering typically 8 cm in height. Furthermore, wet floor heating takes a long time to install and requires a high level of professional expertise. If buried pipes or heating membranes are damaged, the concrete filling layer must be removed, a complex process. Summary of the Invention

[0011] The technical problem to be solved by this application is: in response to the above problems, a low-temperature floor heating system is proposed, which has low energy consumption, heats up immediately after turning on, adopts a fully dry construction method and does not form scale.

[0012] The technical solution of this application is:

[0013] A floor heating structure includes a floor heating pipe for carrying hot water and a plurality of floor blocks located above the floor heating pipe. Each of the floor blocks is composed of a metal corrugated plate, a panel fixed to the panel on the metal corrugated plate, and a floor buckle fixedly connected to the side of the metal corrugated plate. The metal corrugated plate is laid above the floor heating pipe and is thermally connected to the floor heating pipe. The plurality of floor blocks are connected by the floor buckles that are interlocked.

[0014] Based on the above technical solutions, this application also includes the following preferred solutions:

[0015] The metal corrugated plate comprises:

[0016] upper plate body,

[0017] a lower plate body arranged parallel to and below the upper plate body, and

[0018] A corrugated core layer fixedly connected between the upper plate body and the lower plate body;

[0019] A buckle installation gap is formed between the upper plate body and the lower plate body around the corrugated core layer, and the floor buckle is embedded in the buckle installation gap and is welded or bonded to the upper plate body and / or the lower plate body.

[0020] The upper plate body and the lower plate body are steel plates or aluminum plates, and the corrugated core layer is steel corrugated or aluminum corrugated.

[0021] The metal corrugated plate is a rectangular plate, and the corrugated core layer is a wavy structure including a plurality of crests and a plurality of troughs alternately arranged along the width direction of the metal corrugated plate.

[0022] The plurality of wave crests are bonded and fixed to the upper plate, and the plurality of wave troughs are bonded and fixed to the lower plate.

[0023] The floor heating structure also includes a heat insulation pad laid on the ground, and the floor heating pipe is laid on the heat insulation pad.

[0024] A downwardly concave pipe groove is provided on the upper surface of the thermal insulation pad, and the floor heating pipe is embedded in the pipe groove.

[0025] The upper surface of the thermal insulation pad is covered with a heat-conducting film, a portion of which is sandwiched between the outer pipe wall of the floor heating pipe and the groove wall of the pipe groove, and the metal corrugated plate is arranged against the upper surface of the heat-conducting film.

[0026] A heat-conducting pipe clamp is clamped on the floor heating pipe, and the heat-conducting pipe clamp has a heat-conducting top surface located at the notch of the pipe groove, and the heat-conducting top surface of the heat-conducting pipe clamp is vertically abutted against the lower surface of the lower plate body.

[0027] The heat-conducting top surface is formed with a downwardly concave glue groove, and the glue groove is provided with a heat-conducting glue for bonding the lower plate body and the heat-conducting pipe clamp.

[0028] This application can achieve the following beneficial effects:

[0029] 1. The floor blocks of this floor heating structure are directly laid on top of the floor heating pipes, and are connected to each other into a whole with the help of the floor buckles provided by the floor blocks. There is no need to pour sand and gravel concrete. It is a fully dry construction method with high installation efficiency. The floor blocks can be easily dismantled and reused.

[0030] 2. Metal corrugated boards have excellent compression and bending resistance, which is exactly adapted to the use environment of floor panels laid flat on the ground and just meets the use requirements of floor panels. Based on this, the upper panel can be made as thin as a few millimeters, which greatly saves the use of wood and stone, especially precious wood and stone. At the same time, the metal corrugated board has a high thermal conductivity rate, which can quickly guide the heat of the floor heating pipe below to the thin panel, and then dissipate it into the room through the thin panel, quickly raising the indoor temperature. This makes the floor heating structure heat up immediately after it is turned on, and the water temperature in the floor heating pipe does not need to be high. It only needs to be maintained at a low temperature of around 30°C for normal use. Not only is the energy consumption extremely low, but it also does not form scale.

[0031] 3. Metal corrugated board not only has excellent compression and bending resistance, but also uses less material, is light in weight and low in cost. The new type of floor block formed by combining it with the panel is affordable and easy to transport, and has broad market prospects.

[0032] 4. All the corrugated holes in the corrugated core layer of the metal corrugated board are set vertically to further enhance the ability of the floor block to withstand vertical loads and vertical impacts, which is exactly in line with the application environment of the floor.

[0033] 5. A layer of insulation pad is laid between the ground and the floor heating pipe. The insulation pad blocks the downward heat transfer path of the floor heating pipe, ensuring that most of the heat is transferred upward to the floor blocks, thereby improving the energy utilization rate of the floor heating structure.

[0034] 6. The insulation pad is made of foam plastic, which has a certain degree of flexibility and thus has protective properties for the floor heating pipes. In addition, the foam plastic is lightweight, environmentally friendly, and has excellent sound insulation properties.

[0035] 7. The thermal insulation pad is made of polystyrene resin foam board, which also has good fire resistance.

[0036] 8. Many concave pipe grooves are opened on the upper surface of the insulation pad, and the floor heating pipes are embedded in the aforementioned pipe grooves. This not only solves the problem of unstable position and easy movement of the floor heating pipes, but also prevents the floor heating pipes from being deformed and flattened due to pressure.

[0037] 9. A heat-conducting pipe clamp with a heat-conducting top surface is clamped on the floor heating pipe. The heat-conducting top surface of the heat-conducting pipe clamp is vertically abutted against the lower plate of the metal corrugated plate, and heat-conducting glue is arranged between the two, thereby improving the heat conduction efficiency of the floor heating pipe and the metal corrugated plate.

[0038] 10. The peaks and troughs of the corrugated core layer are arranged alternately along the width direction of the corrugated substrate, thereby greatly improving the bending resistance of the rectangular floor blocks in the length direction.

[0039] 11. Each wave crest of the corrugated core layer is bonded and fixed to the upper plate, and each wave trough is bonded and fixed to the lower plate, so that each wave crest and each wave trough of the corrugated core layer are tightly combined with the upper and lower plates, so that the floor blocks can withstand large bending torque in the width direction.

[0040] 12. When the panel is a fragile structure such as marble or ceramic tile, the transportation and handling of the floor blocks is more convenient with the support of the metal corrugated substrate underneath, which greatly reduces the damage rate of marble and ceramic tile floor blocks during transportation.

DETAILED DESCRIPTION

[0050] To make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meanings understood by persons having ordinary skills in the field to which this application belongs. The words "a" or "an" and the like used in the patent application specification and claims of this application do not indicate a limitation on quantity, but rather indicate the presence of at least one.

[0052] In the description of the specification and claims of this application, the terms "upper", "lower", "horizontal", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting this application.

[0053] Now, embodiments of the present application are described with reference to the accompanying drawings.

[0054] Figures 1 to 4 A preferred embodiment of the floor heating structure of the present application is shown, which includes a floor heating pipe 1 for carrying hot water and a plurality of floor blocks 2 located above the floor heating pipe.

[0055] The key improvement of this embodiment lies in the fact that each floorboard 2 is composed of a corrugated metal sheet 201, a panel 202 abutting and fixed to the upper surface of the corrugated metal sheet, and floor clips 203 fixedly connected to the side edges of the corrugated metal sheet. The corrugated metal sheet 201 is laid over and thermally connected to the floor heating pipes 1, and the individual floorboards 2 are connected by interlocking floor clips 203.

[0056] As can be seen, the individual floor panels 2 of this floor heating structure are installed directly on top of the floor heating pipes 1 and connected together using the floor clips 203 provided by the floor panels 2. This eliminates the need for pouring sandstone concrete, allowing for a fully dry installation method. This highly efficient installation also allows for easy removal and reuse. Furthermore, the high thermal conductivity of the corrugated metal panels allows for rapid heat transfer from the floor heating pipes 1 to the panels 202, which then dissipate the heat into the room, rapidly raising the indoor temperature.

[0057] Panel 202 (the upper surface) is exposed to the environment and is accessible to people. Panel 202 is typically a marble slab, a tile slab, a wooden board, or a plastic board. The aforementioned plastic board includes a relatively soft rubber board or plastic board. In this embodiment, panel 202 is a wooden board, and the thickness of the board is only a few millimeters.

[0058] The above-mentioned panel can also be a wear-resistant coating applied on the upper surface of the metal corrugated board. The wear-resistant coating has a certain thickness and is in a fixed state. It is "plate-shaped" in appearance and is also an optional panel structure.

[0059] Similar to traditional corrugated boards, the metal corrugated board 201 of this embodiment also includes: an upper board 201a, a lower board 201b arranged parallel to and below the upper board, and a corrugated core layer 201c fixedly connected between the upper and lower boards.

[0060] Furthermore, the upper plate 201a is bonded to the upper surface of the corrugated core layer 201c by means of an adhesive (hot melt adhesive film), and the lower plate 201b is bonded to the lower surface of the corrugated core layer 201c by means of an adhesive (hot melt adhesive film). Of course, the upper and lower plates can also be welded to the corrugated core layer.

[0061] The panel 202 is bonded to the upper surface of the upper plate 201a with an adhesive, thereby bonding the panel 202 to the corrugated metal sheet. To enhance the vertical compressive and impact resistance of the panel 202 and prevent it from fracturing under vertical loads or impacts (particularly when the panel is a marble or ceramic tile slab), the adhesive used to bond the panel 202 to the upper plate 201a is preferably continuous and dense, thereby forming a continuous and dense adhesive layer (not shown) between the panel 202 and the upper plate 201a.

[0062] The above-mentioned "continuous and dense adhesive layer" can be achieved by increasing the amount of adhesive used, or by sandwiching a hot melt adhesive film between the panel 202 and the upper plate body 201a, and first allowing the aforementioned hot melt adhesive film to melt at a high temperature, and then allowing the molten hot melt adhesive film to solidify at a low temperature.

[0063] Unlike conventional corrugated sheet metal, the area of ​​the corrugated core 201c in this embodiment is smaller than that of the upper and lower panels 201a, 201b. Furthermore, each side of the corrugated core 201c lies inboard of the corresponding side of the upper and lower panels 201a, 201b. This creates a floor clip installation gap 201d around the corrugated core 201c between the upper and lower panels 201a, 201b. The floor clip 203 is inserted into this gap 201d, and the portion of the floor clip embedded in this gap 201d is welded to the upper and lower panels 201a, 201b.

[0064] It should be noted that the floor clip 203 can also be welded to only one of the upper plate 201a or the lower plate 201b. This design has the advantage of improving the assembly efficiency of the floor clip and the corrugated metal sheet. However, it has the disadvantage of slightly weaker connection strength between the floor clip and the corrugated metal sheet.

[0065] In addition, adhesive may be coated on the floor buckle 203, and the floor buckle portion embedded in the floor buckle installation gap 201d may be bonded and fixed to the upper plate 201a and / or the lower plate 201b using the adhesive.

[0066] In this embodiment, the metal corrugated plate is a corrugated aluminum plate, wherein the upper plate body 201a and the lower plate body 201b are both aluminum plates, and the middle corrugated core layer 201c is aluminum corrugation.

[0067] The upper plate 201a, lower plate 201b and corrugated core layer 201c in the above-mentioned metal corrugated plate can also be made of other materials. For example, the upper plate 201a and lower plate 201b can also be steel plates, and the middle corrugated core layer 201c can also be stainless steel corrugated plates.

[0068] In this embodiment, the shape of the corrugated substrate matches the shape of the floorboards, both being long, rectangular sheets. Similar to most corrugated sheets, the corrugated core layer 201c in this embodiment also has a wavy structure, with multiple alternating crests and troughs. As we know, the bending strength of a long, rectangular sheet in the length direction is weaker than its bending strength in the width direction, while the bending strength of a wavy corrugated core layer in a direction perpendicular to the arrangement of the crests and troughs is much higher than its bending strength in a direction parallel to the arrangement of the crests and troughs. Based on this, in this embodiment, the crests and troughs of the wavy corrugated core layer are alternately arranged along the width of the corrugated substrate, thereby significantly improving the bending resistance of the rectangular floorboards in the length direction.

[0069] As previously mentioned, upper plate 201a is bonded to the upper surface of corrugated core 201c using an adhesive (hot-melt adhesive film), while lower plate 201b is bonded to the lower surface of corrugated core 201c using an adhesive (hot-melt adhesive film). Therefore, by simply controlling the bonding process when bonding the upper and lower plates and the intermediate corrugated core, each peak of the corrugated core can be bonded to upper plate 201a, and each trough to lower plate 201b. This ensures that each peak and trough of the corrugated core is tightly bonded to the upper and lower plates, further enhancing the bending strength of the rectangular floorboard.

[0070] In some other embodiments of the present application, the crests and troughs of the corrugated core layer can be arranged as planar structures, with the crests (the upper surface) of each planar structure positioned against and bonded to the upper panel (the lower surface), and the troughs (the lower surface) of each planar structure positioned against and bonded to the lower panel (the upper surface). This greatly increases the bonding area and strength between the corrugated core layer and the upper and lower panels, preventing the upper or lower panels from peeling off from the corrugated core layer during use.

[0071] If the above-mentioned floor heating pipe 1 is laid directly on the ground 6 (generally the indoor floor, including the floor surface) and is in direct contact with the ground 6, then a large part of the heat of the hot water in the floor heating pipe 1 will be transferred downward to the ground 6 and lost. Based on this, this embodiment also lays a layer of insulation pad 3 on the ground 6, and the above-mentioned floor heating pipe 1 is laid on the aforementioned insulation pad 3. The insulation pad 3 blocks the downward heat transfer path of the floor heating pipe 1, ensuring that most of the heat is transferred upward to the floor block 2.

[0072] The above-mentioned thermal insulation pad 3 is preferably made of foam plastic with a certain degree of flexibility so as to have protective properties for the floor heating pipe 1. In addition, the foam plastic is lightweight, environmentally friendly, and has excellent sound insulation performance.

[0073] Furthermore, the thermal insulation pad 3 is made of polystyrene resin (also a kind of foam plastic) with fireproof performance.

[0074] If the floor heating pipes 1 are placed directly on the flat surface of the insulation mat, they will easily move and become unstable, and will also be easily deformed and flattened under the vertical pressure of the floor panels above. To address this, this embodiment has multiple downwardly concave pipe grooves 301 formed on the upper surface of the insulation mat 3, and the floor heating pipes 1 are embedded in these grooves 301.

[0075] If the floor heating pipe 1 were in direct contact with the metal corrugated sheet 201, the two would be in linear contact, resulting in a small heat transfer area. Furthermore, the plastic floor heating pipe 1 is easily bent and deformed, resulting in poor contact with the upper floorboards, and heat transfer efficiency cannot be guaranteed. To address this issue, this embodiment clamps multiple thermally conductive pipe clips 4 onto the floor heating pipe 1. These clips 4 have a thermally conductive top surface located at the notch of the pipe groove 301. The thermally conductive top surface of the clips 4 vertically abuts the lower surface of the lower plate 201b of the metal corrugated sheet. The thermally conductive pipe clips 4 provide an indirect thermal connection between the floor heating pipe 1 and the floorboards 2.

[0076] Furthermore, in this embodiment, a downwardly recessed glue groove 401 is formed on the heat-conducting top surface of the heat-conducting pipe clamp 4, and a thermally conductive glue 5 for bonding the lower plate body 201b and the heat-conducting pipe clamp 4 is provided in the glue groove 401, further ensuring good thermal conductivity between the heat-conducting pipe clamp 4 and the metal corrugated plate 201.

[0077] In order to allow adjacent floorboards to be connected very conveniently with the help of the floor clips 203 thereon, this embodiment provides a floor clip 203 on each side of the rectangular metal corrugated plate 201, so that each floorboard has four floor clips 203. In addition, two of the floor clips 203 are male clips 203a, and the other two are female clips 203b. Figure 3 During assembly, the male buckles 203a and female buckles 203b of two adjacent floor panels are fastened together, as shown in FIG. Figure 5 .

[0078] It should be noted that the two male buckles 203a and the two female buckles 203b on the floorboards can have different structures. For example, the floorboard disclosed in Chinese invention patent publication number CN101910528B has male and female buckles on its two long sides that engage with each other in an angular flipping manner, while its two short sides have male and female buckles of another structure that engage with each other in a vertical displacement manner. Clearly, the claims of this application do not exclude this possibility.

[0079] Figure 6 The second preferred embodiment of the floor heating structure of the present application is shown. The floor heating structure is basically the same as the structure of the first embodiment, except that the length of the heat conducting pipe clamp 4 in this embodiment is basically equal to the length of the floor heating pipe 1.

[0080] Figure 7 The third preferred embodiment of the floor heating system of the present application is shown. This floor heating system has essentially the same structure as the first embodiment, differing in that: instead of a heat-conducting pipe clamp, this embodiment coats the upper surface of the thermal insulation pad 3 with a layer of heat-conducting film 7. A portion of the heat-conducting film 7 is sandwiched between the outer wall of the floor heating pipe 1 and the wall of the pipe groove 301. The metal corrugated sheet 201 (specifically, the lower plate 201b) is arranged in contact with the upper surface of the heat-conducting film 7. This creates a large contact area between the heat-conducting film 7, the floor heating pipe 1, and the metal corrugated sheet 201, allowing heat from the floor heating pipe 1 to be quickly transferred to the metal corrugated sheet 201.

[0081] The thermally conductive film 7 is preferably aluminum foil.

[0082] The above are merely exemplary embodiments of the present application and are not intended to limit the scope of protection of the present application. The scope of protection of the present application is determined by the appended claims.
