[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water pipe unit used when constructing a hot water floor heating floor.

[0002]

2. Description of the Related Art As a hot water type floor heating floor for heating by passing hot water through a hot water pipe arranged on a floor base, for example, as shown in FIGS. 10 (a) and 10 (b), A floor finishing material 51 having a built-in hot water pipe 52 is sequentially laid on a floor base 53, or a pipe housing groove 62 for housing a hot water pipe 64 on the back surface as shown in FIG. 11A. After laying the floor finishing material 61 on which the ridges are formed on the floor base 63 as shown in FIG. 2B, the pipe housing is installed from the end face side of the floor finishing material 61 as shown in FIG. There is one in which a hot water pipe 64 is inserted into the groove 62.

By the way, the floor heating floor shown in FIG.
Since the hot water pipe 52 is built in the floor finishing material 51 in advance, it is only necessary to lay the floor finishing material 51 on the floor base material 53. Even when the floor finishing material 51 is nailed to the floor base material 53,
If the designated position is nailed, there is an advantage that the hot water pipe 52 built in the floor finish material 51 is not damaged, but since the hot water pipe 52 is divided for each floor finish material 51, When laying the floor finish material 51 on the floor base material 53, the hot water pipe 5 built in the adjacent floor finish material 51.
Since the two must be sequentially connected through a connector or the like, there is a problem that the workability of laying the floor finish material 51 is poor.

In the floor heating floor shown in FIG. 11, it is not necessary to connect a hot water pipe to each floor finishing material, but a long hot water pipe 64 is provided in the pipe accommodating groove 62 of the floor finishing material 61 already laid. It is a labor-intensive work to pipe the pipe while making a U-turn, and again, it is impossible to construct a floor heating floor efficiently.

In order to solve the problems in the conventional hot water type floor heating floor, the inventor of the present application filed Japanese Patent Application No. 2001.

If b is laid, the U-turn panel 74 on the end side of the attachment
The other U-turn portion 72b of the hot water pipe 72 cannot be accommodated in the U-turn portion of the pipe accommodating groove 75b in b.

Therefore, the construction operator of the hot water type floor heating floor 70 must carefully lay the U-turn panel 74b on the starting side in consideration of the expansion / contraction state of the hot water pipe 72. There is a problem that the U-turn panel 74b cannot be efficiently laid in a short time.

Further, in the state where the floor finishing material 74 is laid,
Since the accommodation state of the hot water pipe 72 in the pipe accommodation groove 75 cannot be confirmed, even if the U-turn panel 74b on the starting side is properly laid in consideration of the expansion / contraction state of the hot water pipe 72, it is laid in that way. If the U-turn panel 74b on the starting side is not properly laid, the floor finishing material 74 once laid must be peeled off and re-layed again. There is a problem such as not becoming.

[0011] Therefore, an object of the present invention is to provide a hot water pipe unit for a hot water floor heating floor, which can efficiently construct a hot water floor heating floor without considering expansion and contraction of the hot water pipe due to temperature change. To do.
