Description

[Detailed Description of the Invention] This invention relates to a hot water pipe for floor heating that is laid or buried in the floor of a house for floor heating.

Conventionally, hot water pipes for this type of floor heating have been made of long, bendable pipes made of synthetic resin or metal such as copper, and are designed to fit the floor structure of the house as shown in Figure 1 or 2. There is a known structure which is bent as shown in FIG. 1 and then laid or buried in the floor structure. Hot water pipe A shown in Figure 1
is a straight section 2 of a predetermined length from one end 1 of hot water pipe A.
A curved part 3 is formed by leaving a curved part 3, a straight part 4 continuous to this curved part 3 is formed parallel to the straight part 2, and a curved part 5 continuous to this straight part 4 is formed. The other end 6 of the hot water pipe A is formed by sequentially bending the hot water pipe A on the same plane. Located far away from. Further, after the hot water pipe A thus formed is laid or buried in the floor structure 7 shown by the two-dot chain line in the figure, hot water is poured into one end of the hot water pipe A as shown by the arrow in the figure. By supplying water from one end 6 and discharging it from the other end 6, floor heating is performed. Hot water pipe B shown in FIG. 2 has a flow of hot water from hot water pipe A shown in FIG.
Almost across the hot water pipe A from one end 1 to the other end 6
However, by bending the hot water pipe B at approximately the middle position 8, it is possible to flow in the opposite direction. However, due to the shape of the above-mentioned conventional hot water pipes for underfloor heating, there is a risk of them becoming tangled when stacked, making them difficult to handle, and also because they occupy a relatively large area. However, it has some drawbacks that tend to lead to a decrease in transportation efficiency. Such defects have hindered the mass production of hot water pipes in specialized factories, and have forced them to be formed on-site using specialized bending machines and jigs.

This idea was made in view of the conventional circumstances mentioned above, and involves bending a bendable tube so that the curvature of the curved part on one end side is smaller than the curvature of the curved part on the other end side, and To provide hot water pipes for floor heating that are stacked in a spiral shape, solve the problems of the conventional method, are easy to handle, improve transportation efficiency, and are easy to install or bury in a floor structure. The purpose is to

This invention will be explained in detail below based on an embodiment shown in FIGS. 3 to 5.

The symbol C in the figure indicates a hot water pipe for floor heating.
This hot water pipe C is a bendable pipe body 9 of a predetermined length formed of synthetic resin or metal such as copper.
is bent so as to form two curved portions 10 and 11 having different curvatures at a predetermined distance D, and
It is constructed by stacking the tube bodies 9 so as to form a concentric spiral shape. The tube body 9
One end portion 12 is located above the laminated tube bodies 9 (the third
It is located on one side (upper part in the figure) and is located so as to protrude from one curved part 11 toward the outside of the spiral shape. Further, the other end portion 13 of the tube body 9
is the lower part of the laminated tube body 9 (lower part in Fig. 3)
located on the side opposite to the side on which the one end 12 is located, and similar to the one end 12,
It is positioned so as to protrude from one curved portion 11 toward the outside of the spiral shape. What is indicated by the symbol 14 is
A floor structure such as a floor panel that constitutes the floor of a house (not shown), and this floor structure 14 has four frames 15,
It is constructed by assembling 16, 17, and 18 into a rectangular shape, and pasting surface materials 19 and 20 on the upper and lower surfaces thereof. Moreover, inside this floor structure 14, there are a plurality of recesses 21 in the upper part (upper part in FIG. 5),
21... are formed with a predetermined pitch 22, 2
3 are fixed to be parallel to the frames 15, 16, and heat insulating materials 24, 24... are fixed to the inner surface of the surface material 19 attached to the lower surface (lower side in FIG. 5). It is arranged by

Next, a procedure for installing the hot water pipe C for floor heating according to this invention will be explained.

Hot water pipes C are manufactured by stacking them in a spiral shape as shown in Fig. 3 in a special factory, etc.
2 and 13 are separated, and both ends 12,
13 are extended so that the straight line parts are parallel to each other. Hot water pipe C has one curved portion 11
Since the curvature of the other curved part 10 is larger than that of the fourth curved part 10, the fourth curved part 10 is
As shown in the figure, the curved portions 11 with small curvature are desuperimposed and placed adjacent to each other on the same plane, and the curved portions 12 with large curvature are partially crossed and placed on almost the same plane. The hot water pipes C are placed next to each other so that the hot water pipes C can be uniformly extended. By this extension, the distance between both ends 12 and 13 of the hot water pipe C is made to be a distance that approximately matches the length of one side of the floor structure 14, and then the straight part between both curved parts 10 and 11 is adjusted. part of the floor structure 14.
It is supported by being fitted into the recesses 21, 21, . . . 2, 23. At this time, both ends 1 of hot water pipe C
2 and 13 are provided with appropriate recesses in the frame 16, and are positioned so as to protrude from the recesses to the outside of the floor structure 14. In this way, the floor structure 1 of the hot water pipe C
4 is laid down. If the floor structure 14 is a panel body as shown in this embodiment, after the hot water pipes C are laid as described above, the hot water pipes C are further installed on the upper surface of the floor structure 14 (upper part in the figure). The hot water pipe C can be buried by attaching the surface material 20 so as to cover it. Next, the transportation of the hot water pipe C will be described as follows.

Since the hot water pipe C before being expanded is formed by stacking the pipes in a spiral manner so that the cross-sectional shape has an irregular elliptical shape, the occupied area can be reduced.
Further, since no unnecessary gaps are formed in the stacked hot water pipes C, even if a large number of hot water pipes C are stacked, they will not become entangled, making transportation and handling easier.

Furthermore, in manufacturing the hot water pipe C, supporting members with different diameters are positioned at appropriate intervals,
This can be easily done by simply winding a long tubular body around both support members in an appropriate number of turns. Furthermore, the distance between the two curved portions 10 and 11 of the hot water pipe C can be changed as appropriate by changing the spacing between the supporting members, so that the shape of the hot water pipe C can be readily adapted to the required shape.

As described above, the hot water pipe for floor heating according to this invention bends a bendable pipe body so as to form two curved portions with different curvatures at a predetermined distance apart.
In addition, since the tubes are stacked to form a concentric spiral shape, the area occupied before installation can be reduced, and a large number of tubes can be stacked by preventing entanglement. , thus improving transportation efficiency and simplifying handling. Furthermore, the hot water pipes for floor heating can be laid or buried by simply stretching the laminated pipe bodies, making the work easier. Furthermore, hot water pipes for floor heating can be manufactured by simply winding a long pipe body for an appropriate length between a pair of supporting members having different diameters and placed at an appropriate interval. , it can be manufactured easily and mass-produced.

According to this invention, it is possible to provide a hot water pipe for floor heating that can achieve the various practical effects described above.
