Detailed Implementation
[0024] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.
[0025] Example 1
[0026] like Figures 1 to 4 As shown in the figure, this embodiment designs a prefabricated underfloor heating installation structure, including EPS composite board 1.
[0027] The EPS composite board 1 includes a polystyrene foam layer and an aluminum foil covering 17 on the upper surface of the polystyrene foam layer. The thickness of the polystyrene foam layer is generally 3-5 cm. The aluminum foil covering 17 is adhered to the upper surface of the polystyrene foam layer, thereby reflecting the heat energy of the underfloor heating pipes 2 to a certain extent.
[0028] A pipe groove for embedding underfloor heating pipes 2 is provided on the upper surface of EPS composite board 1. The groove wall is also covered by aluminum foil 17. The pipe groove includes several straight groove sections 15 and several curved groove sections 16. The straight groove sections 15 and curved groove sections 16 are combined to form a loop to facilitate the installation of underfloor heating pipes 2.
[0029] The straight groove section 15 has a protruding tongue 14 extending to the opposite side at the groove edge. That is, the protruding direction of the protruding tongue 14 is the other groove edge of the straight groove section 15. The protruding tongue 14 can prevent the underfloor heating pipe 2 from coming out of the pipe groove. Compared with the method of using the groove wall of the pipe groove to press against the underfloor heating pipe 2, the method of blocking with the protruding tongue 14 has lower processing requirements for the pipe groove. At the same time, it is also easier to control the gap width between the underfloor heating pipe 2 and the groove wall of the pipe groove, reducing the probability that the underfloor heating pipe 2 will be squeezed out of the pipe groove when radial thermal expansion occurs.
[0030] The width of the bend section 16 is greater than the diameter of the underfloor heating pipe 2, so that an expansion joint is formed between the underfloor heating pipe 2 and the wall of the bend section 16. When the underfloor heating pipe 2 is heated and undergoes axial elongation, the expansion joint can provide space for the expansion and contraction of the underfloor heating pipe 2, effectively reducing the probability of it being squeezed out of the pipe groove during thermal expansion.
[0031] The EPS composite board 1 can be assembled from several splicing blocks, and the splicing seams of the splicing blocks (Figure 1 The aluminum foil tape is not only capable of connecting the splicing blocks together, but also reduces the splicing joint between the splicing blocks, and reduces heat loss.
[0032] The pipeline groove is filled with the heat-conducting cement 5, which covers the gap between the floor heating pipeline 2 and the groove wall of the pipeline groove, and not only reduces the shaking of the floor heating pipeline 2 in the pipeline groove, but also realizes the heat conduction upward, improves the heating efficiency of the indoor environment, and can adaptively change when the floor heating pipeline 2 is thermally expanded and extruded outward, thereby improving the stability and reliability of the installation of the floor heating pipeline 2.
[0033] The splicing blocks include the first splicing block 11 and the second splicing block 12, the first splicing block 11 is provided with only the straight groove section 15, and the second splicing block 12 is provided with both the straight groove section 15 and the curved groove section 16, so that the first splicing block 11 with a unified standard can be used in the floor heating installation of different house types, and only the second splicing block 12 needs to be specially customized, thereby reducing the cost of the floor heating installation.
[0034] In the floor heating installation, the EPS composite board 1 in the embodiment is laid on the ground, and the aluminum foil tape is used to bond the splicing blocks; then the floor heating pipeline 2 is installed in the pipeline groove, and the end of the floor heating pipeline 2 is connected to the hot water pipe and the return pipe; the heat-conducting cement 5 is filled in the gap of the pipeline groove, so that the upper surface of the EPS composite board 1 is flat; finally, the floor is directly laid above the EPS composite board 1.
[0035] Embodiment 2
[0036] On the basis of the structure of the embodiment 1, in order to reduce the deformation of the floor heating pipeline 2 at the curved groove section 16, the pull line groove 13 is arranged between the starting point and the ending point of the curved groove section 16, the pipe clip 3 for fixing the floor heating pipeline 2 is arranged at the starting point and the ending point of the curved groove section 16 respectively, the pull line 4 is connected between the two pipe clips 3, and the pull line 4 is arranged in the pull line groove 13.
[0037] The bending angle of the curved groove section 16 is generally 45°, 180° or 90°, so as to adapt to the wiring of the floor heating pipeline 2.
[0038] The pipe clip 3 can improve the stability of the connection between the floor heating pipeline 2 and the EPS composite board 1, the pipe clip 3 can adopt the existing structure, or can adopt the structure in the attached drawings, Figure 4 Figure 4 The (a) and (b) in the figure are the side view and front view of the pipe buckle 3. The pipe buckle 3 specifically comprises an arch-shaped bend 31, a V-shaped fork and a barb 34; the arch-shaped bend 31 is in the shape of inverted U, and a V-shaped fork is arranged at each end of the arch-shaped bend 31, the opening of the V-shaped fork is downward, and a barb 34 is arranged at the lower end of the V-shaped fork. The opposite sides of the two barbs 34 are provided with inverted sharp points extending to each other, when the V-shaped fork is inserted into the EPS composite board 1, the lower end of the V-shaped fork will be opened to each other and accumulate elastic potential energy, and by using the elastic force of the V-shaped fork itself, the inverted sharp points can be pierced into the EPS composite board 1, thereby reducing the probability of the pipe buckle 3 falling off.
[0039] The outer side wall of the arch-shaped bend 31 is provided with a hanging ear 32, the hanging ear 32 can be in the shape of a ring, and the hanging ear 32 is used for connecting the pull wire 4, the pull wire 4 can be a nylon rope or a iron wire.

The obvious changes or changes derived therefrom are still within the protection scope of the technology.
