DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a house formed by projecting a plurality of inverted beams upward from a horizontal frame and forming a living space above the horizontal frame surrounded by the inverted beams via a floor. About.

[0002]

2. Description of the Related Art An underfloor space which can be used for storing articles by adopting a so-called inverted beam structure in which a plurality of inverted beams project upward from a horizontal frame portion has already been proposed by the present applicant. (For example, see Japanese Unexamined Patent Application Publication No.
No. 1).

[0003]

However, when a pipe around water is stored in a space under the floor in a house employing the inverted beam structure, the service life of the pipe is shorter than the service life of the house frame. It is necessary to replace the pipe before the end of the life of the pipe. In such a case, in order to replace the long pipe, it is necessary to peel off the floor above it over a wide area, and there is a problem that much cost and time are spent.

[0004] The present invention has been made in view of the above-described circumstances, and has as its object to facilitate replacement of a pipe housed in a space under a floor.

[0005]

In order to achieve the above object, according to the present invention, a plurality of inverted beams are projected upward from a horizontal frame portion and are surrounded by the horizontal frame portion and the inverted beams. In a house in which a living space is formed via a floor above a separated underfloor space, the floor comprises an immovable fixed floor and a movable floor slidable to a position overlapping the fixed floor, and a fixed floor. And a piping unit that collects piping around the water in the underfloor space between the horizontal frame and the horizontal frame. The piping unit can be drawn out into the underfloor space between the movable floor and the horizontal frame.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, the piping unit is formed by fixing a plurality of pipes to a support frame in which rods are assembled in a frame shape. I do.

According to a third aspect of the present invention, in addition to the configuration of the first aspect, a riser pipe extending upward from the piping unit and penetrating the fixed floor can be separated from the piping unit and withdrawn upward. There is a feature.

Portion connected to, and one drain pipe 45 _1, the portion where the second water discharge pipe 45 ₂ and the fifth drain pipe 45 ₅ is connected to the main drainage pipe 44 is provided inside of the pipe space 53,
This pipe space 53 is opened and closed by a door 52.

To replace or repair the electric water heater B, first, the hatch 51 provided on the fixed floor 31 is opened, and the electric water heater B stored in the underfloor space 3 is connected to the fourth water supply pipe 43. _4, the fifth disconnecting the drainage pipe 45 ₅ and the first hot water supply pipe 46 _1. Subsequently, the movable floor 15 is slid above the fixed floor 11 to open the underfloor space 3 (article storage section 19) below the second living space 10, and the electric water heater B is connected to the pair of movement guide means 38. , 38 in the direction of the arrow a in FIG. A new electric water heater B or a repaired electric water heater B can be returned to the original position in the reverse procedure.

To replace the piping unit U, after removing the electric water heater B as described above, the riser pipes 50 connected to the bathtub 32, the toilet bowl 33, the wash basin 34, the sink 35, and the pan 36 for the washing machine are provided. From the piping unit U. This operation will be described with respect to the toilet 33, for example. As shown in FIG. 11B, after the toilet 33 is removed, the screw portion is loosened and the riser tubes 50, 50 are connected to the elbows 49, 49.
Just pull it up and pull it out. The main water pipe 42
The first water supply pipe 43 for _a third water supply pipe 43, _third and fourth
Connecting portions of the feed water pipe 43 _4, and first drain pipe 45 ₁ to the main drainage pipe 44, the second drain pipe 45 ₂ and the fifth drain pipe 45
The separation of the connection portion ₅ can be easily performed by opening the door 52 of the pipe space 53.

The pipe unit U separated from the main water supply pipe 42, the main drain pipe 44 and the riser pipes 50 as described above slides on the upper surface of the horizontal frame part Sh as shown in FIG. 2 It is pulled out to the underfloor space 3 (article storage section 19) below the living space 10 in the direction of arrow b in FIG. Thus, a new piping unit U is mounted at the original position in the reverse procedure.

As described above, the electric water heater B and the piping unit U can be drawn into the underfloor space 3 below the movable floor 15, so that the electric water heater B and the piping unit U can be removed without removing the fixed floor 31. Replacement and repair can be performed, and the cost and time required for the operation can be significantly reduced.

Although the embodiments of the present invention have been described above in detail, the present invention is not limited to the above embodiments, and various design changes can be made.

For example, rollers and casters can be used so that the electric water heater B and the piping unit U can be moved with a small force. Further, instead of combining the piping units U into one unit, the piping units U may be combined into two or more units. Further, the movable floor 15 can be slid by a driving source instead of being slid manually. The fixed floor 11 is not always necessary to provide a recess 11 _1, it may be flat. Further, the present invention is not limited to apartment houses, but can be applied to detached houses.

[0034]

As described above, according to the first aspect of the present invention, a piping unit that collects piping around water is disposed in a space below the floor between the fixed floor and the horizontal frame portion. Can be drawn into the underfloor space between the movable floor and the horizontal frame portion, so that the pipe can be replaced at a small cost and time without removing the fixed floor.

According to the second aspect of the present invention,
Since the piping unit is configured by fixing a plurality of pipes to the support frame in which the rods are assembled in a frame shape, it is possible to collectively replace the pipes in a compact manner and greatly improve workability.

According to the third aspect of the present invention,
Since the riser pipe extending upward from the piping unit and penetrating the fixed floor can be removed upward, the riser pipe does not become an obstacle when replacing the piping unit.
