Description

[Detailed description of the invention] This invention relates to a floor heating panel that heats a room from the floor using hot water.

An example of the structure of a conventional floor heating panel will be explained with reference to FIGS. 1 to 9. A circular pipe 1 for passing hot water shown in FIG. 1 is covered with a protective sheet 3 as shown in FIG. 2 is fixed, a heat insulating material 4 is injected between the pipe and the back paper 5, and a pipe end face 6 and a pipe end face 7 are provided at two corners to create a connection part and a floor panel 8 is formed. Furthermore, the floor panel 9 with connecting portions provided at symmetrical positions is also formed to have a similar structure. The required number of floor panels 8 and 9 configured as described above is set according to the size of the room, and the floor panels 8 and 9 are combined by the method shown in FIGS. 4 and 5 to connect the pipe end face 6 and the pipe. Connect end face 7 to joint part 1
Join with 0. 11 is an inlet portion, and 12 is an outlet portion.

6, 7, 8, and 9 show various aspects of the joint portion 10, and FIG. 6 shows the case of brazing, in which a sleeve 13a is covered and both sides thereof are brazed 13b. .

Fig. 7 shows the case where a rubber hose is used, and the rubber hose 14a is covered and hose bands 14 are attached to both sides of the rubber hose.
Tighten and secure with b.

FIG. 8 shows a case where a union joint is used, and the pipe end surfaces 6 and 7 are connected by the union joint 15.

FIG. 9 shows a case where an O-ring is used, and a sleeve 16b is attached to the pipe end surfaces 6, 7 via an O-ring 16a.
Install airtightly.

The floor panels 8 and 9 constructed in the above state are heated by allowing hot water to flow through the circular pipes 1 piped to the floor panels 8 and 9 by passing hot water from the inlet portion 11 to the outlet portion 12. By transmitting energy through the protective sheet 3 and to the surface plate 2, the entire floor surface is heated to heat the room.

Furthermore, due to the function of the heat insulating material 4, the thermal energy from the circular pipe 1 is structured so that the heat transfer to the lower side is minimized and the heat is effectively transferred to the surface.

Since the conventional floor panels 8 and 9 are constructed as described above, when the floor panels 8 and 9 are combined and the underlying floor surface is uneven, the combined portion of the floor panels 8 and 9 will be damaged due to the load from above. There were cases where there was a step and damage occurred.

This idea was made to eliminate the above-mentioned drawbacks, and by providing convex projections integrated with the surface board on both sides of the back of the floor panel in a staggered pattern on the left and right, it was possible to prevent the occurrence of steps. It is something. This idea will be explained below.

An embodiment of this invention will be explained with reference to FIGS. 10 to 16.

As shown in FIG. 10, the floor panel 21 and the floor panel 22 are connected by a chimney board 23. As shown in FIG. As shown in FIG. 11, the floor panels 21 and 22 are constructed by fixing a resin pipe 24 for passing hot water to a top plate 26 with a protective plate 25, and then attaching a heat insulating material 27 to a back sheet 28.
It is formed by injection between. A part of the back surface before injecting the heat insulating material 27 is as shown in FIG. 12, and the end of the pipe 24 is supported by a pipe holder 29. 30 and 31 are pipe end faces.

Next, the piping will be explained with reference to FIG. 13 and FIG. 14, which is a partially detailed view thereof. A T-shaped sleeve 33 and an I
A shaped sleeve 34 is fixed, and the parent pipe 3
5, 36 to one T on the lower right side of Fig. 14.
The other I-shaped sleeve 34 (not shown) on the upper right side is connected to the hose band 37.
Another pair of T-shaped sleeve 33 and I-shaped sleeve 34 are also connected in the same way, but the parent pipes 35 and 36 are configured to intersect in the middle. The pipe 24 that is piped over the entire surface of the floor panels 21 and 22 is fixed with a hose band 37 from one end of a T-shaped sleeve 33, and the floor panel 21 is configured with a holder 38 and a holder 39 at the shortest distance as shown in FIG. It connects to the tunnel section 40, crosses diagonally between the chimney boards 23, passes through a similar tunnel section 40 of the floor panel 22 (see Fig. 15), enters the floor panel 22, and returns to the tunnel section 40 through meandering piping. , similarly return to the floor panel 21. Furthermore, the floor panel 21
The pipe is meanderingly connected to the T-shaped sleeve 33,
It is fixed with a hose band 37.

U-turn portion 41 of meandering pipe 24
Holders 38 and 39 are provided at the base, and a blind cover 42 is provided at the entrance of the tunnel portion 40 after piping. A heat insulating material 27 is injected into the floor panel 21 and the floor panel 22 piped in the above state to obtain the cross-sectional structure shown in FIG. 11.

As a result of the play in the pipe 24 being created in the tunnel section 40, which is composed of the respective holders 38 and 39 diagonally intersecting between the floor panels 21 and 22 and the chisel board 23 constructed as described above, as shown in FIG. As shown in the figure, the floor panel 21 and the floor panel 22 can be folded over each other by utilizing the flexibility of the resin pipe 24.

Since the floor panel 21 and the floor panel 22 are connected by a chimney board 23, they can be handled as a pair.
Regarding construction, as shown in Figure 16, the number of sets is determined according to the size of the room, and they are laid on the floor. The joint portion 43 is formed by covering the end surfaces of the T-shaped sleeve 33 and the I-shaped sleeve 34 with a sleeve 44a, brazing both sides 44b, or covering the ends with a rubber hose 45a, as shown in FIGS. 17 to 20.
Tighten and fix both sides with hose bands 45b, or use union joints 46 to connect pipe end face 30,
31 or pipe end faces 30,3
1, the sleeve 47b is airtightly attached via an O-ring 47a.

The floor panels 21 and 22 constructed in the above state allow hot water to be introduced from the inlet portion 48, so that the hot water that has flowed through the main pipe 35 enters the pipe 24 from the T-shaped sleeve 33 into the floor panels 21 and 22. , returns from the other T-shaped sleeve 33 , enters the parent pipe 36 and returns to the outlet section 49 .

Thermal energy possessed by the hot water is transferred through the protection plate 25 and then to the surface plate 26, thereby raising the temperature of the entire floor surface and heating the room.

Note that due to the function of the heat insulating material 27, the thermal energy from the pipe 24 is suppressed from being transferred to the lower side to a minimum, and is effectively transferred to the surface side.

In FIG. 10, FIG. 12, and FIG. 16, a convex projection 50 is provided on one of the back sides of the floor panels 21, 22 and integrated with the surface plate 26 of the floor panels 21, 22, and further Convex projections 51 are provided at staggered positions on the other surface.

When the above-mentioned floor panels are combined, since the convex protrusions 50 and 51 are provided in a staggered manner as shown in FIG. 21 or 22
The structure is such that it is inserted into the bottom of the

In this state, when the floor panels 21 and 22 are buried when the foundation floor surface has some unevenness, the convex protrusions 50 and 51 will not be entangled with each other even if a load is applied from above to the mating portion of the floor panels 21 and 22. Since the floor panels 21 and 22 are attached to each other, there is no difference in position between the floor panels 21 and 22.

As explained in detail above, according to this idea,
Since the convex protrusions are configured to intertwine with the lower side of the mating floor panel in a staggered manner when combined with the surface plate, there is an advantage that the conventional level difference between panels can be improved.
