Description

Technical Field

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

[0002] In traditional underfloor heating construction, ensuring a level surface and a proper drainage slope are key challenges. The conventional approach relies on manual precision control of the concrete backfill thickness and slope, which is not only cumbersome and inefficient but also susceptible to human error, leading to poor surface flatness, improper slope, frequent water accumulation, and severely impacting the effectiveness of the underfloor heating system and the building's quality. Even in some modular underfloor heating systems, the lack of simple and effective leveling and slope-finding structures makes it difficult to precisely adjust differences in height between modules and the drainage slope, failing to meet the needs of diverse application scenarios.

[0003] A search revealed prior art publication number CN222670172U, which discloses a prefabricated EPP underfloor heating module, including a base plate located at the bottom of the entire device. Multiple protruding columns are fixedly installed on the base plate, and underfloor heating pipes are installed in the gaps between the protruding columns. Limiting blocks are fixedly installed on the side ends of the base plate, and snap-fit ​​components are installed on both sides of the limiting blocks. In this device, the underfloor heating module has snap-fit ​​components installed on the limiting blocks. Adjusting the locking columns on the connecting rods by simultaneously manually adjusting the pressing rods on both sides facilitates adjustment. A first spring facilitates the return of the locking columns to their original position. Pressing the pressing rods downwards retracts the locking columns, facilitating the disassembly of the assembled underfloor heating base plates. Releasing the pressing rods automatically returns the locking columns to their original position, enabling the assembly and disassembly of the entire underfloor heating system.

[0004] However, existing prefabricated underfloor heating modules lack simple and effective leveling and sloping structures, making it impossible to accurately adjust the height differences and drainage slopes between modules. This makes it difficult to adapt to the different height requirements of sloping and horizontal panels, and cannot guarantee the stable installation and effective heat dissipation of underfloor heating modules under different terrain conditions, thus limiting the widespread application of underfloor heating modules in diverse application scenarios.

[0005] Therefore, based on the above search and combined with existing technologies, a prefabricated underfloor heating module is proposed to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, an adjustment assembly is incorporated to allow the cylinder, rotating column, and collar to work together, enabling flexible adjustment of the base plate's height and angle, as well as stable installation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In one typical implementation of this application, please refer to Figures 1-5 As shown, a prefabricated underfloor heating module includes: a base plate 1, a plurality of protruding columns 2 fixedly installed on the top surface of the base plate 1, underfloor heating pipes 3 installed in the gaps between the protruding columns 2, and threaded grooves 4 opened at the four corners of the top surface of the base plate 1.

[0024] The adjustment components are provided in four sets, and are respectively located in four threaded grooves 4.

[0025] The adjustment assembly includes: a cylinder 5, which is rotatably installed in a threaded groove 4 via an external thread 6 on its outer surface; a fixing post 7 is fixedly installed on the bottom surface of the cylinder 5; a circular groove 8 is opened on the bottom surface of the fixing post 7; and an internal thread 9 is provided on the inner wall of the circular groove 8.

[0026] The adjustment assembly also includes a rotating column 10, which is rotatably mounted in a circular groove 8 via an external thread 11 on its outer surface. A wedge block 14 is provided on the bottom surface of the rotating column 10 via a rotating component. The adjustment assembly also includes a limiting component.

[0027] Based on the above features, when underfloor heating needs to be installed on the drainage slope, the workers will rotate the column 5 into the threaded groove 4 through the external thread 6. Then, according to the height of the drainage slope and the previous horizontal template, the rotating column 10 will be rotated out of the groove 8 so that the template on the drainage slope is consistent with the height of the previous horizontal template.

[0028] The limiting component includes a magnetic rod 12, which is fixedly installed on the top surface of the circular groove 8. A limiting hole 13 is provided on the top surface of the rotating column 10, and the magnetic rod 12 is adapted to the limiting hole 13.

[0029] The above features can prevent vibrations during construction from causing changes in the adjusted height. Specifically, when the rotating column 10 is rotated out of the circular groove 8 to a suitable position, the magnetic rod 12 will adhere to the inner wall of the rotating column 10 to prevent the rotating column 10 from shifting.

[0030] The rotating component includes: a fixed disk 15, two fixed disks 15 are provided, which are respectively fixedly installed on the two side walls of the wedge block 14, and a rotating column 16 is rotatably connected between the two fixed disks 15. A collar 17 is fixedly installed on the outer surface of the rotating column 16.

[0031] Through the above features, the base plate 1 can be stably installed on the drainage slope, and the angle of the wedge block 14 can be adjusted. Specifically, when it is necessary to adjust the height of the rotating column 10 as it rotates out of the circular groove 8, the operator only needs to move the wedge block 14 to rotate. The rotating column 10 rotates synchronously. The inclined surface of the wedge block 14 is provided with anti-slip texture. The inclined surface of the wedge block 14 fits against the inclined surface of the drainage slope. When it is necessary to adjust the angle of the wedge block 14, it is only necessary to move the wedge block 14.

[0032] The top surface of the collar 17 is fixedly connected to the bottom surface of the rotating column 10. The inner wall of the rotating column 10 is made of a material that can be attracted by the magnetic rod 12, such as nickel.

[0033] Working principle:

[0034] In use, the base plate 1 is first placed in the designated installation position. Multiple raised columns 2 are fixedly installed on the top surface of the base plate 1, and the gaps between these raised columns 2 are used to install the underfloor heating pipes 3. Threaded grooves 4 are provided at the four corners of the top surface of the base plate 1. When the height of the base plate 1 needs to be adjusted to fit the drainage slope, the operator can rotate the rotating column 10, allowing it to move up and down in the circular groove 8, thereby adjusting the height of the wedge block 14 so that the template on the drainage slope is at the same height as the previous horizontal template. During the adjustment process, the magnetic rod 12 will adhere to the inner wall of the rotating column 10, preventing the rotating column 10 from shifting due to vibrations generated during construction, ensuring that the adjusted height remains stable. When the angle of the wedge block 14 needs to be adjusted, the operator only needs to move the wedge block 14, causing the rotating column 16 and the collar 17 to rotate, thereby changing the angle of the wedge block 14 to better fit the slope of the drainage slope, ensuring that the base plate 1 is stably installed on the drainage slope.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
