FIG. 10 shows a ninth embodiment of the present invention, in which the joist 1
The floor heating unit 10 of the present invention is mounted between the joists 14 and 14 while being supported by the mounting brackets 30.

The mounting bracket 30 is formed of a metal plate, and is fixed by driving a nail into a nail hole 32, and the locking parts 31, 31 are embedded in notches formed in the joists 14, 14, and the locking parts 31, 31 and It is flush with the joists 14, 14.

FIG. 11 shows a tenth embodiment of the present invention, in which a channel 15 forming a floor heating unit 40 is not provided with a rack locking surface, has a U-shaped cross section, and has a width narrower than the interval between adjacent joists. and has a predetermined length. When installing such a floor heating unit 40 between the floor joists, the mounting bracket 30 shown in the tenth embodiment may be used, and the floor heating unit 40 may be placed on the mounting bracket 30.

In this case, the upper surface of the floor heating unit 40 should be flush with the joists.

In addition, regarding the lamination of the heat storage material and the heat insulating material, the embedding of the energized heating element, and the attachment of the thin metal plate and aluminum vapor-deposited paper to the upper surface of the unit in the 10th embodiment, see Examples 1 to 7 (Figures 1 to 8). can be selected as appropriate.

FIG. 12 shows an eleventh embodiment of the present invention, in which the underfloor heating unit 50 does not have a channel formed by the outer shell material as in the previously described embodiments, and the heat storage material 20 is replaced by the heat insulating material 19 as described above. It is surrounded by the front, rear, left, right, and lower parts, and is composed of an energizing heating element 21 embedded in this heat storage material 20, and has a width narrower than the interval between adjacent joists and a predetermined length.

Here, as the heat insulating material 19, the heat storage material 20, and the energizing heating element 21, the various materials mentioned above can be appropriately selected, but it is preferable to use hard polyurethane, hard polystyrene, etc. as the heat insulating material 19.

Furthermore, a thin metal plate or aluminum vapor-deposited paper can be attached to the upper surface of the floor heating unit 50 as appropriate, as in the floor heating unit 10 described above.
The embedding of the energized heating element can also be selected as appropriate, as in the unit 10 described above. To attach the unit 50 of the eleventh embodiment to the joists, first install the mounting bracket 30 between the joists 14 and 14, and then install the unit 50 on the mounting bracket 30 one after another.
Make sure to put it on.

Note that the upper surface of the unit 50 and the joist are flush with each other.

Floor heating unit 10 of the present invention as described above
When laying the joists, for example, as shown in FIG.
4 and 14 and drive them into the nail holes 19 to fix the floor heating unit 10 to the joists 14. In the same way, install the units one after another between the joists, and then attach the energized heating element 21.
After connecting the lead wires to the terminal box, lay a carpet etc. directly on the floor heating unit 10,
Alternatively, a floor plate 25 may be placed on the unit 10 as shown in FIG.
Or lay tatami.

In addition, although Fig. 1 shows the case where the joist 14 is passed directly on top of the main pull 13,
Lay a floor board on top of this, pass the joist over this floor board,
A floor heating unit can also be installed between these joists as described above.

As described above, the floor heating units of the first invention and the second invention both have a U-shaped cross section.
Because it is a channel formed of shell material that has a predetermined length and a width narrower than the spacing between the juxtaposed joists,
It can be treated as a complete member.

Therefore, there is no need to make any further modifications to the unit itself at the construction site other than wiring for energization.

Furthermore, the inside of the channel is filled with a heat insulating material, the heat storage material is buried above the heat insulating material, the surface of the heat storage material is flush with the surface of the heat insulating material, and the energized heating element is buried in this heat storage material. The structure is simple.

In addition, once the length and spacing of the joists are determined, manufacturing is easy and mass production is possible, which not only reduces the price, but since it is a single completed member, it can be stored after manufacturing, and can be stored at the construction site. Easy to transport to.

Moreover, since the heat insulating material, heat storage material, and current-carrying heating element are housed within the channel formed by the outer shell material, they are sufficiently protected against external shocks, and are protected against vibrations and shocks during storage, transportation, and construction. Damage can be prevented.

In addition, in the first invention, since a mounting locking surface portion for mounting on the upper surface of the joist is provided at one end of both side walls of the channel, the unit of the present invention can be fitted between the joists installed in parallel, and the unit can be fitted on the upper surface of the joist. The unit can be attached simply by supporting the mounting rack locking surface, making construction extremely simple and significantly improving work efficiency.

On the other hand, in the second invention, although the mounting rack locking surface part in the first invention is not provided, the unit can be similarly mounted by placing it on the mounting bracket installed between the joists installed in parallel. can be easily attached, and the same effects as the first invention can be achieved.

Furthermore, if both side walls of the channel formed of the outer shell material in the first and second inventions are made to come into contact with the sides of each joist after construction, this will help reinforce each joist and improve the strength of the channel itself. As a result, it is possible to sufficiently prevent the entire floor from being bent, deformed, etc., and it is possible to reliably prevent damage to the electrical connection portion, which is considered to be relatively weak in this type of floor heating system.

Also, when removing the heater when heating is not required, it is only necessary to remove it from between the joists installed side by side, which is also extremely simple.

Furthermore, in the first and second inventions, the heat storage material is buried above the heat insulation material filled inside the channel, and the energized heating element is buried in this heat storage material, so that the heat storage material acts as a heat insulator as a sea. It is like an island surrounded by the heat storage material, and there is no part where the heat storage material is in direct contact with the channel, so the heat generated by the energized heating element embedded in the heat storage material is
It is possible to avoid wasteful discharge to the outside through the channel as much as possible.

Furthermore, since the heat storage material is buried above the heat insulation material and the surface of the heat storage material is flush with the surface of the heat insulation material, only the surface of the heat storage material is not covered with the heat insulation material, and Alternatively, since a carpet or the like is laid through the floorboard, the heat from the energized heating element can be effectively used for heating the heating space without wasting it, and the thermal efficiency can be further improved.

Furthermore, in the first and second aspects of the present invention, since the heat storage material as described above does not come into direct contact with the channel, the channel is not heated, and therefore dew condensation on the outer surface of the channel can be prevented.

Furthermore, in the present invention, as described above, the heat insulating material is the sea and the heat storage material is in the form of an island, so that the rapid temperature drop in the heating space when the electricity to the energized heating element is cut off is caused by heat radiation from the heat storage material. Therefore, it can be prevented more effectively.
