[0042] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. Each example is provided by way of explanation of the present application and does not limit the present application. In fact, it will be clear to those skilled in the art that modifications and variations can be made in the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as part of one embodiment can be used in another embodiment to produce yet another embodiment. Therefore, it is expected that the present application includes such modifications and variations within the scope of the appended claims and their equivalents.

[0043] In the description of this application, the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and do not require that this application must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application. The terms "connected", "connected", and "set" used in this application should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0044] In the present application, a dry overhead floor heating structure comprises: a plurality of floor heating modules and an overhead structure; the plurality of floor heating modules are arranged on the overhead structure so that there is a grouting gap between the plurality of floor heating modules and the basic structure layer; at least some of the plurality of floor heating modules are provided with grouting holes, so that pouring material is poured into the grouting gap through the grouting holes until the grouting gap is filled to achieve self-leveling to form a grouting layer; since the overhead structure comprises a plurality of first footings and a plurality of second footings, the grouting gap is formed between the plurality of floor heating modules and the basic structure layer in the following manner Gap: For any assembly position formed between the floor heating modules, the first anchor is set through the assembly position to level and support the multiple floor heating modules forming the assembly position; for the side of the floor heating module close to the wall, the second anchor is set through the floor heating module to level and support the floor heating module, thereby realizing the targeted setting of the first anchor and the second anchor based on the laying position of the floor heating module in the overhead structure, thereby forming effective point contact for the overall floor heating module, providing an effective overhead design, and further realizing the construction of a grouting gap between the floor heating module and the basic structure layer. Furthermore, pouring grouting material into the grouting gap through the grouting hole until the grouting gap 3 is filled and self-leveling is achieved to form a grouting layer. After the pouring grouting material filling the grouting gap is solidified, at least part of the structure of the first footing and the second footing that is exposed outside the floor heating module can be removed, and at least part of the structure of the first footing and the second footing that is located below the floor heating module remains in the dry overhead floor heating structure, so that after the construction of the dry overhead floor heating structure is completed, there will be no hollow gap, and no echo when it is stepped on. In addition, the pouring grouting material can achieve self-leveling during the pouring process, and effectively support the floor heating module after solidification, thereby avoiding deformation of the floor heating module due to long-term stress.

[0045] Figure 1A This is one of the overall schematic diagrams of a dry overhead floor heating structure according to an embodiment of the present application; Figure 1B This is the second overall schematic diagram of a dry overhead floor heating structure according to an embodiment of the present application; Figure 1C This is the third overall schematic diagram of a dry overhead floor heating structure according to the embodiment of the present application. Figures 1A-1CAs shown, it includes: a plurality of floor heating modules 1 and an overhead structure 2; the plurality of floor heating modules 1 are arranged on the overhead structure 2 so that a grouting gap 3 is formed between the plurality of floor heating modules 1 and the foundation structure layer 4; at least some of the plurality of floor heating modules 1 are provided with grouting holes 11, through which grouting material is poured into the grouting gap 3 until the grouting gap 3 is filled and self-leveling is achieved to form a grouting layer. The grouting gap 3 is formed by the plurality of floor heating modules 1 and the foundation structure layer 4.

[0046] In this embodiment, the dry-type overhead floor heating structure is arranged against a wall to prevent the pouring material from leaking sideways. Alternatively, a baffle structure is arranged against a wall, and the dry-type overhead floor heating structure is placed in the baffle structure to prevent the pouring material from leaking sideways.

[0047] Figure 2A This is one of the structural diagrams of the first foot 21 according to an embodiment of the present application. Figure 2B This is one of the structural diagrams of the first foot 21 according to an embodiment of the present application. Figure 2C For the embodiment of this application Figure 2A Schematic diagram of the assembly of the first foot 21. Figures 2A-2C The overhead structure 2 includes a plurality of first footings 21 and a plurality of second footings 22, so that the grouting gap 3 is provided between the plurality of floor heating modules 1 and the foundation structure layer 4 in the following manner: for any assembly position S formed between the floor heating modules 1 (see Figure 1A ), the first foot 21 is set to pass through the T-shaped assembly position S to level and support the multiple floor heating modules 1 forming the T-shaped assembly position S; for the side of the floor heating module 1 close to the wall, the second foot 22 is set to pass through the floor heating module 1 to level and support the floor heating module 1.

[0048] After the poured grout filling the grouting gap 3 solidifies, at least part of the structure of the first anchor 21 and the second anchor 22 exposed outside the floor heating module 1 can be removed, and at least part of the structure of the first anchor 21 and the second anchor 22 located below the floor heating module 1 remains in the dry overhead floor heating structure.

[0049] Alternatively, see above Figures 1A-1CThe plurality of floor heating modules 1 are arranged on the overhead structure 2 in a 1 / 2 staggered arrangement, so that a T-shaped assembly position S is formed between every three floor heating modules 1. At the T-shaped assembly position S, one corner of two floor heating modules 1 is butted against each other, and also against the middle part of the side of another floor heating module 1, thereby ensuring that the three floor heating modules 1 are in surface contact during the laying process, thereby improving the stability of the structure and preventing the floor heating modules 1 from being misplaced.

[0050] Optionally, each of the first foot 21 and the second foot 22 includes: a screw 211, an isolation sleeve 212, a leveling portion 213, and a pressing portion 214. The screw 211 passes through the pressing portion 214, the leveling portion 213, and the isolation sleeve 212 from top to bottom, and abuts against the base structure layer 4. Specifically, the pressing portion 214 and the leveling portion 213 are provided with internal threads to engage with the threads on the screw 211 so as to be movable up and down along the screw 211, thereby achieving leveling of the floor heating module 1 based on the leveling portion 213, and achieving compression and fixation of the floor heating module 1 based on the pressing portion 214.

[0051] The isolation sleeve 212 is positioned outside and below the leveling portion 213, and an assembly gap is formed between the pressing portion 214 and the leveling portion 213, so that the multiple floor heating modules 1 forming the assembly position S can be butted together at the assembly gap. For example, a corner of two floor heating modules 1 and the middle portion of the side of an outer floor heating module 1 can be butted together at the assembly gap.

[0052] The meshing relationship between the leveling portion 213 and the screw 211 allows the leveling portion 213 to move up and down along the screw 211 to level the floor heating module 1. After leveling, the meshing relationship between the pressing portion 214 and the screw 211 secures the floor heating module 1. As previously mentioned, if the leveling portion 213 is provided with an internal thread, during the leveling process, the screw 211 is screwed to cause the leveling portion 213 to move up and down along the screw 211 until the floor heating module 1 is leveled.

[0053] The isolation sleeve 212 is used to isolate the cast material from the screw 211. After the cast material solidifies, the screw 211 and the pressing portion 214 can be removed from the first footing 21, while the isolation sleeve 212 remains in the grouting layer and the leveling portion 213 remains in the floor heating module. The presence of the isolation sleeve 212 prevents the screw 211 from adhering to the cast material, facilitating its removal. The removed screw 211 and pressing portion 214 can be reused, reducing costs.

[0054] Specifically, for example, a nut 215 having an internal thread can be embedded in the leveling portion 213 , and the nut 215 can be sleeved onto the screw rod 211 , thereby providing an internal thread on the leveling portion 213 .

[0055] Optionally, the leveling portion 213 may be T-shaped as a whole, so that the nut 215 can be embedded inside the lower end, and the isolation piece can be sleeved on the outer periphery of the lower end.

[0056] Optionally, the pressing portion 214 may be in an inverted T-shape, so that the pressing portion 214 can be moved downward along the screw 211 by screwing its upper portion, thereby pressing the floor heating module 1 .

[0057] Alternatively, see Figure 2A-2B As shown, the upper end face of the leveling portion 213 included in the first foot 21 is provided with a cylindrical boss 213A, and three ridges 213B are provided around the cylindrical boss 213A along the radial direction of the leveling portion 213. The three ridges 213B form a T-shaped position relationship to position the three floor heating modules 1 forming the T-shaped assembly position S at the assembly gap for docking, thereby avoiding assembly errors of the floor heating modules 1 during the assembly process.

[0058] Optionally, Figure 3A This is one of the structural diagrams of the second foot 22 according to the embodiment of the present application. Figure 3B This is one of the structural diagrams of the second foot 22 according to the embodiment of the present application. Figure 3C For the embodiment of this application Figure 3A Schematic diagram of the assembly of the second foot 22.

[0059] See also Figure 3A-3C The upper end surface of the leveling portion 213 included in the second foot 22 is provided with a cylindrical boss 213A, and the cylindrical boss 213A is embedded in the installation through hole opened on the side of the floor heating module 1 close to the wall.

[0060] Optionally, Figure 4A It is a structural schematic diagram of the floor heating module 1. Figure 4B FIG2 is another structural diagram of the floor heating module 1. In order to facilitate the floor heating module 1 to match the three ridges 213B to form a T-shaped positional relationship, the four corners of the floor heating module 1 are set to a concave shape P (for example, a quarter arc), which seamlessly connects with the area surrounded by the cylindrical boss 213A and each ridge 213B to ensure compact assembly.

[0061] To this end, in addition to the above-mentioned method of passing the second foot through the installation hole of the floor heating module, since a semicircular docking area will also be formed at the corner docking point of the two floor heating modules on the side close to the wall, the semicircular docking area can be used as the assembly gap between the two floor heating modules with reference to the above-mentioned assembly method of the second foot, and the two floor heating modules can be assembled on the same second foot.

[0062] above Figure 4A and Figure 4B The floor heating modules 1 differ in length, but share the same width, enabling the aforementioned 1 / 2 staggered paving. Furthermore, mounting holes M are provided near the four corners of the floor heating modules 1 to facilitate assembly of the second footings 22 with the floor heating modules 1 against the wall. Some floor heating modules 1 have a concave shape L (e.g., a semicircular arc) in the middle, side portions to create a T-shaped assembly position during paving.

[0063] Figure 5A This is another structural diagram of the first foot 21 according to an embodiment of the present application. Figure 5B This is another structural diagram of the first foot 21 according to the embodiment of the present application. Figure 5C This is another structural diagram of the first foot 21 according to the embodiment of the present application. Figure 5D For the embodiment of this application Figure 5A One of the structural diagrams of the middle compression part. Figure 5E For the embodiment of this application Figure 5A The second structural diagram of the middle compression part. Figure 5F For the embodiment of this application Figure 5A Schematic diagram of the assembly of the first foot 21. Figures 5A-5F As shown, the first foot 21 includes: a screw 211, an isolation sleeve 212, a leveling portion 213, and a pressing portion 214. The screw 211 passes through the pressing portion 214, the leveling portion 213, and the isolation sleeve 212 from top to bottom, and abuts against the basic structure layer 4.

[0064] The isolation sleeve 212 is located outside the leveling portion 213 and below the leveling portion 213, and an assembly gap is formed between the pressing portion 214 and the leveling portion 213, so that the multiple floor heating modules 1 forming the assembly position S are docked at the assembly gap.

[0065] Through the meshing relationship between the leveling part 213 and the screw 211, the leveling part 213 moves up and down along the screw 211 to level the floor heating module 1, and after leveling, the floor heating module 1 is fixed based on the meshing relationship between the pressing part 214 and the leveling part 213.

[0066] The isolation sleeve 212 is used to isolate the grouting material from the screw rod 211, so that after the grouting material solidifies, the screw rod 211 and the pressing portion 214 can be removed from the first footing 21, while the isolation sleeve 212 remains in the grouting layer. The leveling portion 213 remains in the floor heating module.

[0067] Optionally, Figure 5A 、 Figure 5B The leveling portion 213 can be an inverted T-shaped structure, and its protruding end is a hollow structure to facilitate the passage of the screw 211. At the same time, its protruding end is provided with an external thread, and the bottom is stuck in the inner groove of the corner of the floor heating module 1. In addition, for the pressing portion 214, the part that engages with the protruding end extends into the inner groove, and the part that engages with the protruding end is also provided with a thread to form a toothed relationship with the thread of the protruding end. The pressing portion 214 is exposed on the outside of the floor heating module 1, specifically a knob structure, so that the knob structure can be easily screwed to increase the depth of the engagement between the pressing portion 214 and the protruding end, so as to achieve the effect of pressing the floor heating module 1. After the poured grout solidifies, the knob structure is turned to reduce the depth of engagement between the pressing portion 214 and the protruding end, thereby removing the pressing portion 214 from the second foot 22, while retaining the isolation sleeve 212 and the leveling portion 213 in the dry overhead floor heating structure, including retaining the isolation sleeve 212 in the grouting layer and the leveling portion 213 in the floor heating module.

[0068] Here, it should be noted that Figure 5A 、 Figure 5B The leveling portion 213 is provided with a cylindrical boss 213A and ridges 213B according to the above method, and the number of ridges can be determined according to the shape of the floor heating module.

[0069] Further, see above Figure 5E A circular ridge 213C is provided under the T-shaped platform of the inverted T-shaped structure of the leveling part 213 to engage with the groove in the mounting through hole provided on the floor heating module 1, so as to position the floor heating module and ensure the stability of the structure during the assembly process to prevent position deviation of the floor heating.

[0070] Here, it should be noted that for the footings in other figures, you can also refer to Figure 5E Circular ridges are provided to position the floor heating module during assembly, ensure structural stability, and prevent position deviation of the floor heating.

[0071] Specifically, for example, similar to the above Figure 2AIn the case of a cross, a cylindrical boss 213A is provided on the upper end surface of the leveling portion 213, and four ridges 213B are provided around the cylindrical boss 213A along the radial direction of the leveling portion 213. The four ridges form a cross-shaped position relationship to position the four floor heating modules (1) forming the cross-shaped assembly position (T) and dock them at the assembly gap.

[0072] When four ribs 213B are provided, they can be applied to a cross-shaped position, that is, at each cross-shaped assembly position T, four floor heating modules 1 are docked at one first foot 21. Of course, in other embodiments, the ribs 213B can also be omitted.

[0073] Figure 6A This is another structural diagram of the second foot 22 according to the embodiment of the present application. Figure 6B This is another structural diagram of the second foot 22 according to the embodiment of the present application. Figure 6C For the embodiment of this application Figure 6A One of the structural diagrams of the middle leveling part. Figure 6D For the embodiment of this application Figure 6A The second structural diagram of the middle leveling part. Figure 6E For the embodiment of this application Figure 6A Schematic diagram of the assembly of the second foot 22.

[0074] like Figures 6A-6E As shown, the second foot 22 includes: a screw 211, an isolation sleeve 212, and a leveling portion 213. The screw 211 passes through the leveling portion 213 and the isolation sleeve 212 from top to bottom and abuts against the basic structure layer 4.

[0075] The isolation sleeve 212 is located outside the leveling portion 213 and below the leveling portion 213. The leveling portion 213 is provided with an assembly gap to connect with the floor heating module 1 on the side close to the wall.

[0076] Through the meshing relationship between the leveling portion 213 and the screw rod 211 , the leveling portion 213 moves up and down along the screw rod 211 to perform leveling on the floor heating module 1 .

[0077] The isolation sleeve 212 is used to isolate the pouring material from the screw rod 211, so that after the pouring material is cured, the screw rod 211 can be removed from the second footing 22 while the isolation sleeve 212 remains in the grouting layer. The leveling portion 213 remains in the floor heating module.

[0078] Optionally, Figure 6A 、 Figure 6B The leveling portion 213 in the embodiment can be an inverted T-shaped structure, and the protruding end thereof is a hollow structure, which is convenient for the screw 211 to pass through, and is similar to the above Figure 5A 、 5B The difference is that there is no external thread, and the bottom of the leveling part 213 forms a support for the floor heating module 1. The interior of the leveling part 213 forms a meshing relationship with the screw 211, so that by screwing the screw 211, the leveling part 213 moves up and down along the screw 211, and then the bottom of the leveling part 213 supports the floor heating module 1, thereby achieving leveling of the floor heating module 1.

[0079] After the poured material is solidified, the screw rod 211 is screwed to remove the screw rod 211 from the second footing 22 , while the isolation sleeve 212 and the leveling portion 213 are retained.

[0080] Similar to the above Figure 2A-2B , Figure 3A-3B , in the above Figure 5A-5B , Figure 6A-6B For example, a nut 215 with an internal thread can be embedded inside the leveling part. The nut 215 is sleeved on the screw rod 211, thereby providing an internal thread on the leveling part 213. By screwing the screw rod 211, the leveling part 213 moves up and down along the screw rod 211, thereby achieving leveling of the floor heating module 1. During removal, the nut 215 remains in the dry overhead floor heating structure.
