DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for installing a housing unit on which a heavy object such as a piano is placed on a foundation.

[0002]

2. Description of the Related Art In recent years, unit houses have been constructed in which factories manufacture living rooms and the like, which are constituent parts of houses, as housing units, and transport and assemble these housing units to building sites. When such a housing unit is installed on a foundation, a grout material is injected into a sheath tube buried in the foundation, and after inserting an anchor bolt attached to a pillar constituting a frame of the housing unit into the sheath tube, the grout material And the housing unit is fixed to the foundation via these anchor bolts and grout material. The level adjustment when the housing unit is installed on a foundation is performed by screwing a level adjustment bolt to an appropriate height at an embedded nut embedded near the sheath tube.

In the case of ordinary housing units, the floor alone can withstand ordinary weight only with such a foundation. On the other hand, in the case of a housing unit on which a heavy object such as a piano is placed, the floor may be bent due to the weight of the heavy object. Therefore, a reinforcing base for receiving a joist is provided substantially at the center of the floor. .

[0004]

As described above, the level adjustment when the housing unit is fixed by the anchor bolts can be easily performed by the level adjustment bolts.
However, the level adjustment at the time of forming the reinforcing foundation is performed by inserting a packing between the joist and the reinforcing foundation, so that it is not as easy as the adjustment using the level adjusting bolt. Therefore, it takes time and effort to perform accurate level adjustment, and there has been a problem in increasing the efficiency of assembling unit houses.

Accordingly, an object of the present invention is to provide a method of installing a housing unit on a foundation, which can easily and accurately adjust the level.

[0006]

According to the method of installing a housing unit on a foundation according to the present invention, an enclosure frame is provided on an upper surface of a foundation on which a floor frame which is horizontally erected below a floor is placed, and this enclosure is provided. After injecting the grout material into the frame, before the grout material is hardened, the floor frame is placed on the grout material, and then the grout material is hardened to support the floor frame material with the grout material. Features. The floor frame is a joist, a beam or the like.

[0007]

When the floor frame of the housing unit is placed on the grout before the grout hardens, the floor frame of the housing unit is maintained at a predetermined height level while sinking into the grout. Thereafter, by hardening the grout under the floor frame, the housing unit is accurately leveled and supported on the foundation via the grout.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a method for installing a housing unit on a reinforcing foundation according to the present invention will be described with reference to FIGS. First, as shown in FIGS. 2 and 3, when building a foundation at a building site, pillars 19 constituting the frame 12 of the housing unit 11 are used.
In addition to the foundation 14 on which the anchor bolt 13 attached to the floor is to be buried, the reinforcing foundation 16 on which the joist 15 which is the floor frame material of the floor 22 is to be mounted. This reinforcement foundation
16 has the same height as the base 14. At this time, the sheath tube 17 and the embedded nut 23 are provided on the foundation 14 at the same time.

Next, along the portion where the joists 15 of the reinforcing foundation 16 are to be arranged, a rectangular enclosure 20 having no bottom is formed.
Is installed. The enclosure 20 is based on the housing unit 11
When installed on top, the joists 15 are filled with grout 21 inside the enclosure 20
It is made of an elastic material such as synthetic rubber so that it can contact with.

Next, a level adjusting bolt 18 on the foundation 14
Is adjusted so that the housing unit 11 is at a predetermined height, and a grout material made of cement mortar is injected into the sheath tube 17. On the other hand, as shown in FIG.
A grout material 21 made of the same cement mortar is poured into the surrounding frame 20 of the reinforcing base 16. The injection amount of the grout material 21 is such that the lower portion 15A of the arranged joist 15 can be buried in the grout material 21.

Next, before the grout material 21 is cured,
Anchor bolts 13 connect a plurality of housing units 11 to a sheath tube 17.
It is installed on the foundation 14 so as to be inserted into the grout material inside. As shown in FIG. 1, these housing units 11
At the same time, the lower part 15 of the joist 15 of the housing unit 11 on which a heavy object such as a piano is placed on the reinforcing foundation 16
A is buried in the grout material 21.

Next, after a lapse of a predetermined time, the grout material 21 is hardened, so that each joist 15 is reliably supported by the grout material 21. In this way, through the joist 15 and the grout material 21 hardened underneath, the housing unit 11 is obtained in which the central portion under the floor is accurately level-adjusted to the predetermined height and supported on the reinforcing foundation 16.

According to the above-described embodiment, the grout 21
After the joist 15 of the housing unit 11 is placed on the grout material 21 before it is hardened, the grout material 21 is hardened, so that the housing unit 11 is placed on the reinforcing base 16 via the grout material 21. It can be supported with the level adjusted accurately. As a result, even if a heavy object such as a piano is placed in the housing unit 11,
There is no risk that the 22 will bend.

Further, since it is only necessary to inject the grout material 21 into the enclosure 20 after providing the enclosure 20 on the reinforcing base 16, the work is simple and the efficiency of assembling the unit house is improved. .

The reinforcing base 16 of the above embodiment is a
Although it had the same height as 14, if the gap between the reinforcing foundation 16 and the joist 15 was large, only the portion of the reinforcing foundation 16 was used to reduce the amount of grout material 21 used. May be built higher than the foundation 14 of the building. Further, in the above embodiment, the case where the floor frame material is the joist 15 is used, but a beam may be used.

[0016]

According to the method of installing a housing unit on a foundation according to the present invention, the level of the housing unit can be easily adjusted.
And can be performed accurately.
