Hereinafter, embodiments will be described with reference to the drawings.

The temperature control mat 10 includes 10 substantially rectangular substrates A to J and a hot water pipe 14 (FIG. 4) as a temperature control pipe arranged in a groove provided on the upper surface of each of the substrates A to J. , The header 20 (FIG. 5) in which the hot water pipes 14 are connected, and the heat soaking sheet material 15 (FIG. 4) arranged so as to cover the upper surfaces of the substrates A to J and adhered to the upper surfaces of the substrates A to J and the like. It is equipped with. In FIGS. 1 and 2, the groove and the hot water pipe are not shown.

Each of the substrates A to J has a board (board) 11 made of foamed synthetic resin, a small joist 12 interposed between the boards 11, and the like. A notch 16 is provided at a corner portion of the substrate A (a corner portion farthest from the substrates B and F).

The substrates A to E are arranged in this order from the left to the right in FIG. 1, and are arranged so as to be foldable. The substrates F to J are also arranged in this order from the left to the right in FIG. 1, and are arranged so as to be foldable.

In this embodiment, the substrates A and F have a width (length in the short side direction of the rectangle) larger than that of the other substrates. The substrates B, C, D, G, H, and I are smaller in width than the substrates A and F, and wider than the substrates E and J. The substrates A and F have the same width, the substrates B, C, D, G, H and I have the same width, and the substrates E and J have the same width.

The boards A and F are connected so as to be folded back. The substrate B and the substrate G are not connected to each other. The substrate C and the substrate H are not connected to each other. The substrate D and the substrate I are not connected to each other. The substrate E and the substrate J are not connected to each other.

A hot water pipe 14 is routed across adjacent boards that are foldable and connected to each other, and the boards are connected to each other by the hot water pipe 14. In the butt portion between the substrates that are foldable and connected, the hot water pipe 14 extends along the butt side direction. Therefore, since the hot water pipe 14 is pulled out from the groove exposed on the side surface of the substrate when the substrates are folded in a mountain or valley, the temperature control mat 10 can be folded in a mountain or valley along the abutting portion of the substrate. ..

The end of each hot water pipe 14 extends to the notch 16 of the substrate A, and the hot water pipe nozzle 22 of the header 20 is connected to the cutout portion 16.

FIG. 5 shows an example of a header suitable for use in this temperature control mat. The header 20 has a rectangular parallelepiped header body 21, a hot water piping nozzle 22 projecting from the side surface of the header body 21, and a main piping nozzle 23 projecting from the lower surface of the header body 21. The hot water pipe nozzle 22 is inserted into the hot water pipe 14, and the two are connected by tightening with a band. The underfloor pipes are the main pipe for sending and receiving hot water from the boiler and the main pipe for returning, and there are two headers 20 for sending and returning as shown in FIGS. 5A and 5B. Is used. Each header 20 is arranged in the notch 16.

After connecting the header 20 and the hot water pipe 14, the temperature control mat 10 may be folded, or the header 20 and the hot water pipe 14 may be connected after the temperature control mat 10 is folded.

In order to fold the temperature control mat 10, as shown in FIG. 2, first, valley folds are made between the substrates A and B and between the substrates F and G, and then mountain folds are made between the substrates B and C and between the substrates G and H. Fold between the boards C and D and between the boards H and I, and fold between the boards D and E and between the boards I and J. As a result, the substrates A to E and the substrates F to J become stacks (first stack and second stack), respectively. Next, the second stack of substrates F to J is folded so as to overlap the first stack of substrates A to E.

As a result, as shown in FIG. 3, a stacked body is formed in which the substrates A, B, C, D, E, J, I, H, G, and F are stacked in this order from the lower side. Since the widths of the substrates A and F are larger than those of the other substrates, the substrates A and F project from the stack. Since the notch 16 provided at the corner of the substrate A is provided at the portion protruding from the stacked body, the header 20 is arranged in the notch 16 and the header 20 and each hot water pipe 14 are connected to each other. However, the header 20 does not hit the stacked body, and damage to the heat equalizing sheet material 15 and the like is prevented.

As another folding method, the method shown in FIG. 7 can be mentioned. In this method, first, the boards A and B and the boards F and G are folded in a mountain, the boards B and C and the boards G and H are folded in a valley, and the boards C and D and the boards H and I are folded in a mountain. Fold it and fold it between the boards D and E and between the boards I and J. As a result, the substrates A to E and the substrates F to J become stacks (first stack and second stack), respectively. Next, the second stack of substrates F to J is folded so as to overlap the first stack of substrates A to E.

As a result, as shown in FIG. 8, a stacked body is formed in which the substrates E, D, C, B, A, F, G, H, I, and J are stacked in this order from the lower side. Since the widths of the substrates A and F are larger than those of the other substrates, the substrates A and F project from the stack. Since the notch 16 provided at the corner of the substrate A is provided at the portion protruding from the stacked body, the header 20 is arranged in the notch 16 and the header 20 and each hot water pipe 14 are connected to each other. However, the header 20 does not hit the stacked body, and damage to the heat equalizing sheet material 15 and the like is prevented.

In order to carry the temperature control mat 10 to the site and then construct it, the temperature control mat 10 is unfolded and the notch 16 is aligned with the floor opening. The end of the main pipe is arranged below the floor opening. The underfloor piping is connected to the header 20 by inserting the main piping nozzle 23 of the header 20 connected to the temperature control mat 10 into the main piping (not shown) from under the floor and tightening with a band.

Therefore, the pipe connection work at the site is only the connection work between the main pipe and the header 20, and the construction work becomes extremely simple.

The above embodiment is an example of the present invention, and the present invention may be a form other than the above.

For example, in the above embodiment, a total of 10 substrates A to J are used, but the number may be about 4 to 20.

Further, although the width dimension (unit: mm) of each substrate A to J is entered in FIG. 1, the present invention is No. 1 in Table 1 below. It can also take dimensions such as 2-6. No. in Table 1 1 is the dimension of the temperature control mat of FIG. The present invention may have other width dimensions.

In the above embodiment, the temperature control pipe is a hot water pipe, but it may be a cold water pipe through which cold water is passed.
