2. Description of the Related Art In order to perform floor heating of hot water between joists provided on a large pulley, a pipe groove is formed on a heat insulating material made of polystyrene foam which is laid on the adjacent large pulley. After laying this heat insulating material between the joists, a method of laying a conducting pipe through which hot water passes through the pipe groove, or using a panel that is pre-piped on a heat insulating material made of polystyrene foam, A method is adopted in which a panel is laid horizontally on a large scale and laid between joists. In any of the constructions, it is necessary to cross the joists and pass through the conduit.

In the former method in which a heat insulating material is laid between the joists, and then the conductive tubes are laid, the winding diameter of the conductive tubes pulled out from the winding drum on site is large, and the conductive tubes are passed under the joists to insulate the conductive tubes. Since it is difficult to pull out and pipe on the material, a part of the joist 11 is cut out as shown in FIG.
The pipe 12 extends through the notch 11a. Also,
In the latter method using a panel that has been previously piped, as shown in FIG.
6 are connected.

If a part of the joist 11 is cut off as in the former method, a problem of a decrease in the strength of the joist occurs and the workability is deteriorated. On the other hand, if the connecting pipes 16 are connected between the conducting pipes 14 and 15 of the adjacent panels 13 and 13 as in the latter method, there is a problem that the number of connecting portions increases and the risk of water leakage naturally increases. is there. Accordingly, an object of the present invention is to provide a method of laying underfloor heating panels under the floor, which can solve such a problem and contribute to improvement of workability.

[0005]

In order to achieve the above object, a method of laying a floor heating panel under a floor, which is a feature of the present invention, is provided on a floor structure in which a joist is crossed over a large pull-up. In the floor heating construction, a pipe groove is provided on the upper surface side of a rectangular heat insulating material formed to a predetermined length with a width that can be laid between joists of the floor structure, and a conduction pipe through which a heat medium passes through the pipe groove. It consists of a large number of floor heating panel units that are laid and a surface material is adhered thereon, and each of these panel units has a predetermined interval between adjacent panel units. By being placed and sequentially connected in a tandem state by the conducting tube, each set is formed, and adjacent ones of the panel unit bodies on one end side of these sets are separated from each other at a predetermined interval by the conducting tube on the lower surface side. Floor heating connected sequentially in a row The panel and the floor unit are supported by supporting shoulders provided on both sides of the panel unit, and the support is formed so that it can be attached to the joist. After wearing, the floor heating panel is pulled up from under the floor so that each set of panel units is located between the joists, and each panel unit is supported by the support, and at the same time, the panel units on one end side of the adjacent set The outside portion of the conductive tube existing between the bodies is positioned below the joist, and the panel unit is laid between the joists in the above-mentioned group unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a floor heating panel used directly for carrying out a method of laying a floor heating panel under a floor according to the present invention will be described with reference to the drawings. 1 to 5, a floor heating panel unit (hereinafter simply referred to as a panel unit) 1, which is a constituent of a floor heating panel, has a rectangular shape having a width and a predetermined length that can be laid between joists of a floor structure. This panel unit 1 is provided with a pipe groove 3 on the upper surface side of the heat insulating material 2, and a conductive pipe 4 for passing a heat medium is laid in the pipe groove 3, and is further provided thereon. This is a configuration in which the surface material 5 is attached.

The plurality of panel units 1 are sequentially connected in a cascade with conductive tubes 4 at predetermined intervals between adjacent panel units 1 (the connection portion is indicated by reference numeral 4a). Each of the panel units 1a on one end side of these groups is sequentially connected to each other in a row at a predetermined interval on the lower surface side of the panel unit 1a by a conducting tube 4. As shown in FIG. 1, a floor heating panel in which all the panel unit bodies 1 and 1 a are apparently connected sequentially by one conducting pipe 4 is configured by connecting portions indicated by reference numeral 4 b). .

Here, the "predetermined distance" of the conductive tube 4 at the predetermined distance is a distance at which the adjacent panel unit bodies 1 and 1a can be folded and overlapped at the connection portion 4a, and The "predetermined interval" in a row state at the predetermined interval means that each set of the panel unit bodies 1 and 1a can be inserted between the joists, and between the supporting shoulders of the support tool to be attached to the joists. This is the interval at which the panel units 1 and 1a can be supported. In the piping pattern shown in FIG. 1, the conductive tube 4 is connected to the panel unit 1a at one end of each group by T.
Each set of panel units 1, 1 is branched by a T-shaped tube t at the entrance side and integrated by a T-shaped tube t at the exit side.
All of the piping patterns a are configured as two systems of parallel piping.

In the floor heating panel thus constructed, when the panel units 1 and 1a are stacked adjacent to each other with the connecting portions 4a and 4b being curved, they are sequentially stacked as shown in FIG. Therefore, it is very convenient for handling during transportation and storage when floor heating is performed on the floor structure. The heat insulating material 2 of the panel unit 1 is made of, for example, a semi-rigid or rigid foam of a thermoplastic resin such as expanded polystyrene or expanded polypropylene having a length of 700 mm, a width of 260 mm, and a thickness of 40 mm. For the pipe 4, a pipe made of a thermoplastic resin, for example, a cross-linked polyethylene pipe having an inner diameter of 4 mm and an outer diameter of 6 mm is used.
As the surface material 5, for example, an aluminum foil is used.

Next, a method of laying underfloor a floor heating panel configured as described above will be described with particular reference to FIGS. In the floor structure for carrying out the method of laying under the floor, a joist 7 is assembled so as to intersect with the joist 6, and each panel unit 1, 1a to be laid between the joists 7, 7 is joisted. A support tool 8 is used to support the upper part.

Support shoulders 8c that can support the panel units 1 and 1a in sets are provided horizontally on both side plate portions 8b and 8b, respectively, and are provided with floor finishing materials on the upper surface plate portions 8a. This is a configuration in which a number of window holes 8d for bonding are provided. The support member 8 is made of a synthetic resin such as polyvinyl chloride, polyethylene, or polypropylene (a low foaming ratio, for example, a foam having a foaming ratio of 15 or less can provide heat insulation). The width of the portion 8c is preferably about 20 mm.

First, after the support members 8 are respectively attached onto the joists 7, the floor heating panel is pulled up from under the floor so that the panel unit 1, 1a of each set is located between the joists 7, 7.
Each panel unit 1, 1a is supported by the supporting shoulder 8c of the support tool 8, and at the same time, the outside portion (connection portion) of the conductive tube 4 existing between the panel units 1a, 1a on one end side of the adjacent set. 4b) is positioned below joist 7. In this way, the panel unit bodies 1 and 1a are laid in sets between the joists 7, 7, respectively, and the work of laying the floor heating panel under the floor is completed.

When the installation is completed, a space is formed by the connecting portion 4a between the panel unit bodies 1 and 1a of each set.
Is inserted. The spacer 9 is formed of the same material as the heat insulating material 2 of the panel unit 1, and has a conductive tube 4 on its upper surface.
