Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a fin for a hot water supply pipe in a floor heating method.

[Conventional technology and its problems]

As shown in Figure 3, the floor heating construction method involves laying pipes that are continuously bent in an S-shape on the floor (insulation control layer), and under the pipes.
There is a system in which a lid fin is attached to the pipe, the overlapping edges of both fins are nailed to the floor, and the heating piping is embedded in the poured mortar (Special Publication No. 58-26501).

However, according to the above-mentioned heating construction method, the poured mortar that embeds the heating pipes enters between the overlapping edges of the upper and lower fins and reaches the hot water pipes, fixing the pipes and making them impossible to expand and contract, which can lead to accidents. There is a close inspection.

The purpose of this invention is to provide a fin in which there is no risk of pouring mortar entering through the joint between the upper and lower fins.

[Means for solving problems]

In order to solve the above problems, this invention has a bottom fin with a U-shaped cross section facing upwards to receive the hot water pipe, and a cover fin with a free edge of a downward "U" shaped part that envelops the hot water pipe and the bottom fin. The fin is a hot water pipe fin for a floor heating method, which has a shape in which horizontal edges facing outwards are interconnected, and the rising portions on both sides of the bed fin are in contact with the inside of the downward-facing "U"-shaped portion of the lid fin. be.

[Effect]

By nailing the horizontal edge of the lid fin to the floor, the left and right rising parts of the bottom fin come into pressure contact with the inner surface of the lid fin, and even if pouring mortar infiltrates, the space formed by the upper and lower fins will remain intact. No infiltration.

〔Example〕

In FIG. 1, 1 is a hot water pipe and 2 is a fin.

The fin 2 consists of a bottom fin 3 and a lid fin 4, and is arranged along the hot water pipe 1. The bottom fin 3 has an upwardly facing "U"-shaped cross section, and the lid fin 4 has a downwardly facing "U"-shaped cross section, and horizontal edges 5 facing outward are connected to the lower edges on both sides.

Figure 2 shows the floor on which piping consisting of hot water pipe 1 and fin 2 is laid, 6 is the concrete layer of the frame,
7 is a moisture-proof layer, 8 is a layer of heat insulating concrete or a hard foamed synthetic resin board, hot water pipe 1 is connected and arranged in an S-shape on layer 8 of heat insulating concrete, etc., and the curved part of the hot water pipe is With the sponge ring 9 attached, attach the bottom fin 3 under the pipe and the lid fin 4 onto the pipe, make the bottom fin 3 stick tightly to the inside surface of the lid fin 4, and tighten the horizontal edge 5 of the lid fin with a nail. 10, fix it to layer 8 of insulating concrete, etc., pour leveling mortar, and connect this pipe to mortar layer 1.
Embed in 1. 12 is a surface layer of a tile or the like.

〔effect〕

The bed fin has a U-shaped cross section facing upwards, and the lid fin is placed over it, so even if some of the mortar gets in through the gaps between the bottom surfaces of the horizontal edges of the lid fin when leveling mortar is poured, the bed fin will not be laid. This has the effect that it is blocked by the rising portions 13 on both sides of the fin and there is no risk of it flowing into the space surrounding the hot water pipe.

Furthermore, since the rising portion of the bottom fin is in contact with the inner surface of the side wall of the lid fin, it is possible to more reliably prevent mortar from flowing into the lid fin.

It is. 1... hot water pipe, 2... fin, 3... bottom fin, 4... lid fin, 5... horizontal edge, 13... rising part of bottom fin.

Claims (1)

[Scope of utility model registration request] In the hot water pipe fin for the floor heating method, which consists of a bed fin and a lid fin arranged along the hot water pipe, the bed fin has an upwardly U-shaped cross section to receive the hot water pipe, and the lid fin The bottom edge of the downward-facing "U"-shaped cross section that covers both the hot water pipe and the bottom fin is connected to horizontal edges facing outward, and the rising parts on both sides of the bottom fin are connected to the downward-facing "U" shape of the lid fin. A fin for a hot water pipe for underfloor heating construction, which is characterized by being in contact with the inside of the shape.
