Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing in which a plurality of reverse beams project upward from a horizontal frame portion and a living space is formed above the horizontal frame portion surrounded by the reverse beams through a floor. Regarding

[0002]

2. Description of the Related Art What has been proposed by the applicant of the present invention to form an underfloor space that can be used for storing articles by adopting a so-called reverse beam structure in which a plurality of reverse beams project upward from a horizontal frame portion is adopted. (For example, JP-A-5-34008)
(See Japanese Patent Publication No. 1).

[0003]

By the way, when an electric water heater is housed in an underfloor space in a house employing such a reverse beam structure, the service life of the electric water heater is shorter than the service life of the skeleton of the house. It becomes necessary to replace the electric water heater before the life of the body is exhausted. In such a case, in order to replace the large electric water heater, it is necessary to peel off the floor above it over a large area, and there is a problem that it consumes a lot of cost and time.

The present invention has been made in view of the above circumstances, and an object thereof is to make it possible to easily replace an electric water heater housed in an underfloor space.

[0005]

In order to achieve the above object, the invention described in claim 1 is such that a plurality of reverse beams project upward from a horizontal frame portion and are surrounded by the horizontal frame portion and the reverse beam. In a house in which a living space is formed above a fixed underfloor space through a floor, the floor is composed of a fixed floor that cannot move and a movable floor that can slide to a position overlapping the fixed floor, and the fixed floor. The electric water heater is arranged in the underfloor space between the horizontal frame portion and the horizontal frame portion, and the electric water heater can be drawn out to the underfloor space between the movable floor and the horizontal frame portion via the movement guide means.

[0006] The invention described in claim 2 is characterized in that, in addition to the structure of claim 1, a hatch is provided on the fixed floor so as to face above the pipe connection portion of the electric water heater.

A second hot water supply pipe 46 ₂ branched from the first hot water supply pipe 46 ₁ and connected to the bathtub 32; and a third hot water supply pipe 46 ₃ branched from the first hot water supply pipe 46 ₁ and connected to the washing machine pan 36. And a fourth hot water supply pipe 46 ₄ branching from the first hot water supply pipe 46 ₁ and connected to the sink 35.

As is apparent from FIG. 9, the various pipes are directly attached to the upper surface of the support frame 41 by U bolts 48 ... Or a bracket 47 welded to the upper surface of the support frame 41.
Are fixed to the U-bolts 48, and the support frame 41 and various pipes are integrated with each other to form a pipe unit U.

The tips of the various pipes, for example, FIG. 11 (a)
As shown in FIG. 5, the tips of the third drain pipe 45 ₃ and the second water supply pipe 43 ₂ are respectively connected to the elbows 49, 49 and the rising pipe 5
It is connected to the toilet bowl 33 via 0 and 50.

As is apparent from FIGS. 6 and 8, the fixed floor 31 above the portion where the fourth water supply pipe 43 ₄ , the fifth drainage pipe 45 ₅ and the first hot water supply pipe 46 ₁ are connected to the electric water heater B.
A hatch 51 is provided in the. Also, the first water supply pipe 43 ₁ ,
The third water supply pipe 43 ₃ and the fourth water supply pipe 43 ₄ are the main water supply pipe 42.
And a portion where the first drain pipe 45 ₁ , the second drain pipe 45 ₂ and the fifth drain pipe 45 ₅ are connected to the main drain pipe 44 are provided inside the pipe space 53,
The pipe space 53 is opened and closed by the door 52.

In order 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 to the fourth water supply pipe 43. ₄ , the fifth drainage pipe 45 ₅ and the first hot water supply pipe 46 ₁ are separated. Then, the movable floor 15 is slid above the fixed floor 11 to open the underfloor space 3 (the article storage portion 19) below the second living space 10 and the electric water heater B is moved to the pair of movement guide means 38. , 38 in the direction of arrow a in FIG. 7, and can be pulled out to the article storage unit 19. The new electric water heater B or the electric water heater B that has been repaired can be returned to the original position by the procedure reverse to the above.

To replace the piping unit U, after removing the electric water heater B as described above, the rising pipe 50 connected to the bathtub 32, the toilet 33, the sink 34, the sink 35, and the washing machine pan 36 ... Is separated from the piping unit U. This operation will be described with respect to the toilet 33, for example. As shown in FIG. 11B, after removing the toilet 33, the threaded portion is loosened and the rising tubes 50, 50 are attached to the elbows 49, 49.
Remove it and pull it upwards. In addition, the main water supply pipe 42
The first water supply pipe 43 ₁ , the third water supply pipe 43 ₃ and the fourth
The connection portion of the water supply pipe 43 _{4 and} the first drain pipe 45 ₁ , the second drain pipe 45 _2, and the fifth drain pipe 45 with respect to the main drain pipe 44.
The connection of ₅ can be separated easily by opening the door 52 of the pipe space 53.

The piping unit U separated from the main water supply pipe 42, the main drain pipe 44 and the rising pipes 50 as described above is slid on the upper surface of the horizontal skeleton portion Sh as shown in FIG. 2 It is drawn out in the underfloor space 3 (article storage portion 19) below the living space 10 in the direction of arrow b in FIG. 12, and is appropriately disassembled there. Then, the new piping unit U is attached to the original position in the reverse order of the above.

As described above, since the electric water heater B and the piping unit U can be drawn out to the underfloor space 3 below the movable floor 15, the fixed water heater B and the piping unit U can be removed without removing the fixed floor 31. The replacement and repair can be performed, and the cost and time required for the work can be significantly reduced.

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

For example, rollers or casters can be used so that the electric water heater B and the piping unit U can be moved with a small force. Further, the piping unit U may be combined into a plurality of two or more units instead of being combined into one unit. Further, the movable floor 15 can be slid by a driving source instead of being manually slid. 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 collective housing and can be applied to detached houses.

[0033]

As described above, according to the invention described in claim 1, the electric water heater is disposed in the underfloor space between the fixed floor and the horizontal skeleton portion, and the electric water heater is used as the movement guide means. Since it is possible to pull out to the underfloor space between the movable floor and the horizontal skeleton part, it is possible to replace or repair the electric water heater with little cost and time without peeling off the fixed floor.

According to the invention described in claim 2,
Since the hatch that faces above the pipe connection of the electric water heater is provided on the fixed floor, the pipe can be easily disconnected by opening the hatch when moving the electric water heater.
