FIG. 2 is a cross-sectional view schematically showing a cross-sectional structure of the hot water mat of FIG. FIG. 1 shows a state in which the mat before attaching the heat dissipation sheet and the magnet (permanent magnet) is viewed from above. FIG. 3A is a plan view showing a flooring material applied to the floor heating hot water mat shown in FIG.
FIG. 3B is a cross-sectional view taken along line 3b-3b shown in FIG.

The basic cross-sectional structure shown in FIG.
Except that a magnet is stuck on the small joist 7, it is not qualitatively different from the conventional mat. However, the size of the radiator tube is larger (10 mm) than the conventional outer diameter of 7.2 mm. That is, as shown in FIG. 2, a pipe groove 41 is dug in the upper surface of the mat plate 5 made of a heat insulating material such as foamed polyethylene. The pipe groove 41 has a substantially square cross section, in which a heat radiation pipe (hot water pipe) 2
Is laid. Warm water of about 60 ° C. flows in the radiator tube 2. The upper surface of the radiator tube 2 is substantially flush with the upper surface of the mat plate 5. The radiator tube is made of cross-linked polyethylene or the like and has flexibility. The mat plate 5 is cut out in some places, and a small joist 7 is embedded therein. The small joist 7 is a belt-like plate made of plywood or the like, and has a role of reinforcing the hot water mat and a role of fixing flooring (flooring or the like) on the hot water mat.

A plate-shaped magnet 8 is adhered on the small joist 7. The magnet 8 is for fixing the flooring material 10 shown in FIG. 3 on the hot water mat 1 by coercive force. On the lower surface of the flooring 10, an iron plate 12 for fixing with a magnet 8 is attached. The iron plate 12 also acts to uniformly radiate heat to the entire floor when heating is performed by the floor heating hot water mat.

A heat radiating sheet 6 made of aluminum foil is adhered to the upper surface of the mat plate 5 including the pipe groove 41 and the upper surface of the magnet 8. The heat radiating sheet 6 is for transmitting the heat released from the hot water in the heat radiating pipe 2 to the upper surface of the hot water mat and radiating the heat from the hot water mat toward an upper room. The hot water mat 1 is placed on the floor structure of the building (concrete or timber floor). On the hot water mat 1, flooring such as flooring is spread according to the type of the room. The flooring material 10 is the small joist 7 of the hot water mat 1
Are laid along the direction perpendicular to the longitudinal direction of the. That is,
The small joist 7 and the flooring 10 are arranged so as to intersect (cross) at right angles.

Next, the planar structure of the mat of this embodiment will be described with reference to FIG. Nine small joists 7 are arranged in the hot water mat 1 of FIG. 1 so as to extend in the vertical direction, similarly to the conventional hot water mat of FIG. The pitch between adjacent small joists 7 is 303 mm. The nine small joists 7 include two types of cross-end type small joists 7a and one end crossing type small joists 7b having different shapes. The leftmost joist 7a is two ends 2
Both 3 and 25 remain inside the mat plate 3 and do not reach the upper side 19 or the lower side 21 of the mat. Further, between the two small joist ends 23 and 25 and the upper and lower sides 19 and 21, the pipe crossing path 13a and the small joist 9 are present.

The pipe crossing path 13a is a portion where the mat plate (the traversing portion mat plate 3a) remains, and one heat radiation pipe 2 passes through the central portion thereof. The small joist 9 is a small joist having a short length (for example, 40 mm). The small joist 9 is located between the outside of the pipe crossing path 13a and the upper side 19 or the lower side 21.
It is arranged so as to be on the extension of the small joist 7a. The small joist 9 is also provided from the viewpoint that a portion to which a magnet (8 in FIG. 2) can be attached is also required on the upper side 19 and the lower side 21 of the mat 1.

In the vicinity of the pipe crossing path 13a (left or right side)
, An auxiliary small joist 11 is installed. Auxiliary joist 1
1 has the same thickness and width as Kojo 7 and Kojo 9 (12 m
m, 45 mm) and the length is 175 mm in one example, and is provided so as to extend from the upper and lower sides 19 and 21 of the mat to the inside of the mat in parallel with the small joists 7. The main purpose of the auxiliary joist 11 is to reinforce the pressure resistance of the portion of the pipe crossing path 13a. That is, when the flooring material is placed on the pipe crossing path 13a in the lateral direction of the drawing, a plate material for supporting the flooring material is required in the mat 1. In particular, on the upper part of the first joist 7, the second jog, and the third jog 7 in the upper left, three rows are continuously arranged in the horizontal direction, and the pipe crossings 13a, 13b,
If the auxiliary small joist 11 does not exist, the load applied to the flooring material on the three-row continuous pipe crossing is applied to the radiator pipe 2 and there is a risk of deformation (floor sink). come.

The second small joist 7b from the left of the hot water mat shown in FIG. 1 is a one-end crossing-type small joist. That is, the lower side of the small joist 7b reaches the mat lower side 21 and has no pipe crossing, and the upper side does not reach the upper side 19, and the pipe crossing path 13b and the small small joist 9 extend beyond the small joist end 27. Exists. These roles are the same as those of the leftmost joist 7a. Note that two radiator tubes pass through the pipe crossing path 13b. The third small joist 7a from the left is again a cross-end type, and the fourth small joist 7b is a single-end cross type. Thereafter, the right and left ends of the small joists 7a and 7b of the one end crossing type are alternately arranged to the right.

The mat plate of the hot water mat 1 in FIG. 1 is divided into a number of blocks. First, as a horizontal division, a line connecting the inner ends of the auxiliary joists 11 on the upper side and the lower side (mat plate cut 4) is used to connect the vertical row mat plate 5 at the center and the horizontal mat plate 3 at both ends. Divided. Further, the vertical mat plate 5 is divided by the small joists 7 in the left-right direction. Further, the traverse mat plate 3 is divided in the left-right direction by the auxiliary joists 11 and the joists 7.
This division is mainly performed from the viewpoint of manufacturing rationalization of improving the processing efficiency of the pipe groove of the mat plate. A plate-like magnet (8 in FIG. 2) is adhered on the small joist 7, the small joist 9, and the auxiliary joist 11, and the mat plate and the small joist of each part are radiated on the upper surface of the mat. The sheet (6 in FIG. 2) forms an integral unit as a whole.

The arrangement of the radiator tubes in the floor heating warm water mat of FIG. 1 will be described. The heat radiation pipe 2 of the hot water mat 1 of FIG. 1 is provided with an inlet 15 and an outlet 17 of the hot water in the upper right corner in close proximity. The radiating pipe 2a extends from the entrance 15 and meanders up and down so as to sew between the small joists 7 to reach the U-turn portion 31 at the lower left corner of the mat. Return to Exit 17. Specifically, the outgoing radiator tube 2 started from the upper right corner
a is the lower side of the mat parallel to the small joist 7b in the downward direction of the figure.
The vehicle travels near 1 (this portion is referred to as a vertical portion 33), turns 90 ° to the left at the transverse portion mat plate 3e, and passes through the piping crossing path 13b in the horizontal direction (this portion is referred to as a transverse portion 35). Then, proceed upward in the longitudinal section mat plate 5a, make a U-turn at the transverse section mat plate 3a ', proceed downward along the small joist 7a (second from the right), and proceed along the transverse section mat plate 3a'. Turn and go left through the crossing pipe 13a. Then, it proceeds upward along the third joist 7b from the right and makes a U-turn at the pipe crossing path 13b of the traverse mat plate 3b, and proceeds downward along the joist 7b. After that, proceed similarly.

According to the above embodiment, since the plate-shaped magnet 8 is adhered on the small joist 7, the small joist 9, and the auxiliary joist 11, the floor heating hot water mat 1 is used for the floor structure of the building. When the plurality of flooring materials 10 are placed on the hot water mat 1 in a direction perpendicular to the longitudinal direction of the small joist 7, the iron plate 12 and the magnet 8 attached to the lower surface of the flooring material 10 A fixing method can be used in which the fixing is performed by the attractive force. For this reason, at the time of repair or maintenance of the floor heating hot water mat, the flooring material 10 can be easily peeled off from the hot water mat 1, and the flooring material 10 can be easily attached to the original hot water mat 1. Therefore, the labor for peeling the flooring material is smaller than that of the conventional product, and the hot water mat itself is not broken or damaged unlike the conventional product.

Further, even if the magnet 8 having a strong coercive force necessary for fixing the flooring 10 is used, for example,
If the end of the flow long material 10 is kneaded, the flooring material 10 can be easily peeled off. This is because the holding force of the magnet 8 is strong against a force in a direction perpendicular to the surface of the flooring material 10, but is slightly weak in a direction parallel or oblique to the surface of the flooring material 10.

Although a permanent magnet is used as the magnet 8 in the above embodiment, an electromagnet may be used, and a rubber magnet or a plastic magnet may be used.

A magnet 8 is stuck on the small joist 7, the small joist 9 and the auxiliary small joist 11 in the hot water mat 1,
An iron plate 12 for attracting the magnet 8 is stuck on the lower surface of the flooring material 10. However, an iron plate is stuck on the small joist 7, the small joist 9, and the auxiliary joist 11 in the hot water mat 1, and this iron plate is attached. It is also possible to attach a magnet for attracting to the lower surface of the flooring material 10.

Although the flooring mounting method utilizing the holding force of the magnet 8 is applied to the hot water mat 1 having the structure shown in FIG. 1, the flooring mounting method can be applied to a hot water mat having another structure. For example, the present invention can be applied to a hot water mat having a structure shown in FIG.

The magnets 8 are attached to all the upper surfaces of the small joist 7, the small joist 9 and the auxiliary joist 11 in the hot water mat 1, but the small joist 7, the small joist 9, and the auxiliary joist are attached. It is also possible to attach the magnet 8 to a part of the upper surface of the magnet 11.
