The first concrete filling area is connected to the opening, and the heat in the underfloor heating installation area is transferred to the drainage pipe to control the water temperature in the drainage pipe to be greater than or equal to 5°C.

[0008] As a further technical solution, the drainage pipe laying area is provided with an insulation partition area and a second concrete filling area. The insulation partition area is set along the bottom end surface of the underfloor heating laying area and the outer surface of the first concrete filling area to separate the first concrete filling area and the second concrete filling area in the drainage pipe laying area.

[0009] As a further technical solution, there is a gap between the outer wall of the drainage pipe and the inner side wall and inner bottom wall of the first concrete filling area.

[0010] As a further technical solution, the longitudinal section structure of the thermal insulation partition area enclosing the second concrete filling area is U-shaped, and correspondingly, the second concrete filling area is provided on both outer sides of the vertical side of the U-shape.

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0026] Example 1

[0027] To improve the utilization rate of indoor radiant heating systems, avoid resource waste, and reduce costs, this embodiment provides a floor structure for frost protection of drainage pipes. (See attached image) Figure 1 This includes structural drop slab area 1;

[0028] The structural drop slab area 1 includes an underfloor heating installation area 11 and a drainage pipe installation area 12 located below the underfloor heating installation area 11.

[0029] The lower part of the underfloor heating installation area 11 is provided with an opening 111. The drainage pipe installation area 12 is provided with a first concrete filling area 3 that wraps around the drainage pipe 2, and the first concrete filling area 3 is connected to the opening 111. The heat in the underfloor heating installation area 11 is transferred to the drainage pipe 2 to control the water temperature in the drainage pipe 2 to be greater than or equal to 5°C.

[0030] It should be noted that in building structural design, the area where the structural elevation of a local floor slab (i.e., the elevation of the top surface of the concrete floor slab) is lower than the elevation of the adjacent floor slab, forming an elevation difference, is called the structural drop zone 1.

[0031] The underfloor heating installation area 11 is equipped with a radiant floor heating system, specifically, underfloor heating pipes 4 are installed within the underfloor heating installation area 11 to transfer the heat emitted by the underfloor heating pipes 4 to the drainage pipe 2. It should be noted that concrete is laid within the underfloor heating installation area 11, and this concrete serves as a medium to transfer the heat emitted by the underfloor heating pipes 4 to the first concrete filling area 3. The heat is then transferred through the concrete filling in the first concrete filling area 3 to the drainage pipe 2, thereby increasing the water temperature within the drainage pipe 2.

[0032] Preferably, the bottom surface of the underfloor heating installation area 11 is provided with a metal layer, which can reflect the radiant heat emitted by the underfloor heating pipe 4 back into the indoor space and prevent heat from being lost to the lower floors through the floor slab.

[0033] The top surface of the drainage pipe laying area 12 is provided with an aluminum foil reflective layer to further improve heating efficiency.

[0034] In the implementation process, the ground structure also includes a leveling layer 5 and a decorative layer 6; the structural drop plate area 1, the leveling layer 5, and the decorative layer 6 are arranged sequentially from bottom to top, and the decorative layer 6 is adjacent to the interior, so that the heat in the underfloor heating installation area 11 is mainly transferred to the interior to increase the indoor temperature.

[0035] The leveling layer 5 is used to level the surface, repair defects, and adjust the flatness.

[0036] The decorative layer 6 is the outermost layer of the building structure. Various decorative materials (such as tiles, flooring, paint, wallpaper, etc.) beautify, protect, and enhance the functionality of the building surface, directly affecting the visual effect and user experience of the space.

[0037] The ground structure also includes a structural layer 7 located below the structural drop slab area 1, and the structural layer 7 is adjacent to the outdoors.

[0038] In the specific implementation process, the drainage pipe laying area 12 is provided with a heat insulation partition area 121 and a second concrete filling area 122. The heat insulation partition area 121 is set along the bottom end face of the underfloor heating laying area 11 and the outer surface of the first concrete filling area 3, so as to separate the first concrete filling area 3 and the second concrete filling area 122 in the drainage pipe laying area 12, avoid heat loss, and thus improve the heat absorption of the drainage pipe 2.

[0039] For example, the thermal insulation partition area 121 may be enclosed by a thermal insulation board;

[0040] Both the first concrete filling area 3 and the second concrete filling area 122 are filled with concrete.

[0041] For ease of operation, there is a gap between the outer wall of the drainage pipe 2 and the inner side wall and bottom wall of the first concrete filling area 3. For example, the gap is less than 100mm, but it should be large enough to facilitate construction by workers.

[0042] In the specific implementation process, the longitudinal section structure of the thermal insulation partition area 121 enclosing the second concrete filling area 122 is U-shaped. Correspondingly, the second concrete filling area 122 is provided on both outer sides of the vertical side of the U-shape, so that the drainage pipe 2 is located in the cavity of the U-shape and is enclosed by concrete.

[0043] The ground structure of this utility model is simple. Under the premise of ensuring that the heat dissipation of the floor heating area meets the requirements, the heat generated by the floor heating system in the floor heating area is transferred to the drainage pipe to prevent the drainage pipe from freezing and cracking. It is efficient, simple to operate, and simpler and cheaper than installing a separate electric heat tracing system for the drainage pipe. It also eliminates the need for an additional heat diffusion plate in the floor heating area, simplifying the process and the space used for the ground structure.

[0044] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0045] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
