  In the present embodiment, the bolt 53 is an M16 steel bolt, and the length of the rail 53 protruding downward from the plate portion 50a of the rail 50 can be adjusted by being screwed into the nut 52 and turning. When the bolt 53 is screwed into the nut 52 and the tip of the bolt 53 is placed on the flange of the back support member 61 and is rotated using a tool such as a wrench, the height of the rail 50 is moved in the vertical direction. Can be made.

(Construction method)
Next, the construction method of the unit room of 1st embodiment is demonstrated.

First, as shown in FIGS. 2A and 2B, the rail 50 is inserted into the lower part of the horizontal member 20.
At this time, an operator stands on the back side (left side in FIG. 2A) and the near side (right side in FIG. 2A) of the unit room body 11, lifts both ends of the rail 50, and The unit room body 11 is carried in.

At this time, the plate portion 50a of the rail 50 comes into contact with the plate portion 20a of the horizontal member 20 and the unit room main body 11 is lifted, so that the unit room main body 11 does not slide off the rail 50. That is, the unit room body 11 is placed on the rail 50.
After carrying the unit room main body 11 into the storage part 70, as shown in FIG. 3, the front end part of the bolt 53 screwed into the nut 52 at the front end part of the rail 50 is connected to the rear support member 61. Place on the flange.
In the present embodiment, the tip of the bolt 53 protrudes from the rail by about 30 mm.

Next, as shown in FIG. 4, the unit room main body 11 is in a state where the near side of the rail 50 is lifted up to a height at which the beam portion 31 does not contact the near side support member 62 and is inclined to the back side of the storage portion 70. Is pushed to the back side of the storage unit 70.
At this time, the plate portion 50a of the rail 50 and the plate portion 20a of the horizontal member 20 are in sliding contact with each other, and the unit room main body 11 slides to the back side of the storage portion 70, so that the predetermined position (the beam portion 31 is on the back side). The adjustment screw 33 screwed into the support plate 32b at the end of the beam member 30 or the position disposed between the support member 61 and the front support member 62 or the back support member 61 and the front support member To the position of the upper part of 62).

  As shown in FIG. 5, the unit room body 11 is slid until the support plate 32 b of the beam member 30 and the adjustment screw 33 are positioned between the back side support member 61 and the near side support member 62, and then tilted. The rail 50 that has been left is leveled. At this time, the length L1 of both ends of the beam portion 31 is set to be shorter than the inner length L2 between the back side support member 61 and the near side support member 62, and the beam portion 31 is short of the back side support member 61 and the near side. It is dropped between the side support members 62.

  Next, when the operator rotates the bolt 53 from the inside of the unit room main body 11 using a wrench or the like, the rail 50 is lowered, and the height of the unit room main body 11 placed on the rail 50 is also reduced. Lower.

  As shown in FIG. 6, when the bolt 53 is continuously loosened, the adjustment screw 33 screwed to the support plate 32b of the beam member 30 comes into contact with the flanges of the back support member 61 and the front support member 62, and the adjustment screw The back side support member 61 and the near side support member 62 support the load of the unit room main body 11 through 33.

  As shown in FIG. 7, when the bolt 53 is further loosened, the rail 50 is separated from the horizontal member 20, and the rail 50 does not bear the load of the unit room main body 11. That is, the beam member 30 and the unit room main body 11 are installed on the back side support member 61 and the near side support member 62.

As shown in FIG. 8, after further loosening the bolt 53 and removing the bolt 53 from the rail 50, the rail 50 is pulled out and removed.
Next, the installation operation of the unit room 10 is completed by adjusting the level of the unit room body 11 by rotating the adjustment screw 33.

(Function)
The construction method of the unit room of 1st Embodiment is comprised as mentioned above, and demonstrates the effect | action below.

  According to the unit room construction method of the first embodiment, since the operator can lift the unit room body from the back side and the near side of the unit room body 11, the unit room body 11 can be used without using a crane or the like. Can be carried by hand.

  Moreover, since the unit room main body 11 can be slid and moved to a predetermined position of the storage unit 70, an operation with an unreasonable posture, which is necessary in the conventional unit room construction method, is not required.

  In addition, since the unit room body 11 is slid by tilting the rail 50, the unit room body 11 can be slid to the back side of the storage unit 70 with a light force.

  Moreover, since the height of the rail 50 can be lowered only by loosening the bolt 53, the rail 50 can be pulled out from the lower portion of the unit room body 11 with a simple operation.

  Further, the level of the unit room body 11 can be easily adjusted by simply turning the adjusting screw 33.

  Moreover, since the space | interval is provided between the unit room main body 11 and the beam part 31, a drain pipe can be pulled horizontally from directly under the unit room main body 11, and the water gradient of a drain pipe is ensured. Can do.

  Further, since the support plate 32b protruding from the upper end portion of the upright portion 32a is installed on the back side support member 61 and the near side support member 62, the position of the beam portion 31 below the upright portion 32a becomes relatively low. The installation height of the unit room main body 11 becomes low. Thereby, the level | step difference between the unit room main body 11 and living space can be suppressed.

[Other Embodiments]
The embodiment of the present invention is not limited to the above, and it is needless to say that various modifications can be made without departing from the gist of the present invention.

For example, the unit room main body 11 is slid in a state where the rail 50 is inclined with the bolt 53 screwed to the tip of the rail 50 being placed on the flange of the back support member 61 and using the bolt 53 as a fulcrum. Not limited.
For example, as shown in FIG. 9, a bolt 53 for height adjustment is also provided at the rear end portion of the rail 50 (the front side of the storage portion 70), and the rail 50 is attached to the back side support member 61 and the front side support member 62. The unit room main body 11 may be slid in a state of being bridged and kept horizontal.
Thus, if the unit room main body 11 is slid, the installation position of the unit room main body 11 can be finely adjusted.

In addition, although the unit room body 11 is placed on the rail 50 and then the rail 50 is bridged between the back side support member 61 and the near side support member 62, the present invention is not necessarily limited thereto.
For example, the unit room body 11 may be placed after the rail 50 is bridged between the back side support member 61 and the near side support member 62.

Moreover, although the rail 50 shall be installed in the lower part of the unit room main body 11 at the time of construction of the unit room of 1st Embodiment, it is not restricted to this.
For example, when constructing a large unit room or a unit room composed of a heavy member, four or more rails 50 may be installed.
Conversely, when constructing a small unit room or a unit room composed of a member having a small weight, the number of rails 50 may be two.
The rail 50 is a steel C-type channel, but is not limited thereto, and may be a rod-like member on which the unit room body 11 can be placed and slid. For example, a round pipe may be used. If it is a round pipe, since it is in line contact with the plate part 20a of the horizontal member 20, the unit room body 11 can be easily slid.

Moreover, although the height adjusting mechanism is the bolt 53, it is not limited thereto, and any mechanism that can change the height of the rail 50 may be used.
For example, a hydraulic jack may be used.

Further, although the level of the unit room body 11 is adjusted by turning the adjusting screw 33 provided on the beam member 30, the present invention is not limited to this.
For example, if the flange surfaces of the back side support member 61 and the near side support member 62 are horizontal at the same height, the adjustment screw 33 may not be provided.

In addition, the horizontal member 20 is extended below the unit room body 11. However, the rigidity of the bottom surface of the unit room body 11 can be secured, and the load of the unit room body 11 is transmitted to the beam member 30. If possible, the horizontal member 20 may not be provided.
For example, a rib formed integrally with the floor material of the unit room body 11 may be formed on the bottom surface of the unit room body 11.
Thus, if the horizontal member 20 is not provided, the structure of the unit room 10 can be simplified.

In addition, the beam member 30 is connected to the horizontal member 20 with a gap through the connecting member 40. However, if the rail 50 can be pulled out, it is not always necessary to leave the gap.
For example, the horizontal member 20 and the beam portion 31 of the beam member 30 may be directly connected without using the connecting member 40.
Thus, if the connecting member 40 is not provided, the structure of the unit room 10 can be simplified.

  Moreover, although the back side support member 61 and the near side support member 62 shall be formed with the H-shaped steel, it is not restricted to this, A foundation made from concrete, resin, etc. may be sufficient. Moreover, it may be arranged on a floor slab or a building beam. Alternatively, it may be a small beam spanned between the beams. Thus, the unit room construction method of the present invention can be applied to buildings of various structural types.

  In addition, the unit room main body 11 is configured to include a bathtub and a floor panel of a washing place inside, but may be configured to include a washstand, a toilet, or the like, or may not include a bathtub. It only has to have a floor panel for the washing area.
