Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an industrialized house built by arranging a plurality of lower box units on a foundation and arranging an upper box unit on top of these lower box units. This relates to a setback box unit that is set back on top of a lower box unit that is placed facing outside, and can be used in industrialized housing built using the unit construction method.

[Background technology]

Recently, unit construction methods have been increasingly used in order to shorten the construction period for housing on site. This unit construction method involves manufacturing multiple modular box units in advance at a factory, transporting these units to the site by truck, and then assembling them on a foundation.

By the way, when constructing a house, there are legal regulations such as diagonal line restrictions, and in order to meet these regulations and increase the building coverage ratio, the second and subsequent floors of the house are set back from the first floor. There are times when you can build a building.

Even in industrialized houses built using the above-mentioned unit construction method, there are some where the second floor is set back from the first floor. FIG. 7 shows the general structure of an industrialized house in which the second floor is set back from the first floor.

In FIG. 7, a plurality of lower box units 50A and 50B are arranged on the foundation 1, and these units 5
An upper hook unit 51 is arranged above 0B. A set hack box unit 52 is arranged on the lower box unit 50A facing outside, and a roof 53 is provided on the front surface of this unit 52. Further, a roof 54 is provided above the units 51 and 52.

A conventional structure of the units 50A, 52 is shown in FIG. 8-9. In these figures, the lower box unit 50A has four pillars 56 attached to the corners of a base formed by combining four lower beams 55 into a rectangular shape, and two ends of these pillars 56. It has a frame structure in which four upper beams 57 are constructed to form a ceiling. This structure is the same for the other lower box unit 50B and upper box unit 51. Note that the lower box units 50A and 50B include an entrance unit, but in the case of this entrance unit and knit, one to one of the lower beams 55 is used.
It has a frame structure in which all or part of the four wires are removed.

Similar to the unit 50A, the setback box unit 52 has four pillars 59 attached to the corners of a rectangular base made up of four lower beams 58, and four pillars 59 at the upper ends of these pillars 59. Although it has a frame structure in which the ceiling is formed by constructing an upper beam 60,
8 and 60 are short beams 55 and 57 of the unit 50A.
It is shorter than .

Here, the setback box unit 52 is
The lower end of the column 59 is supported by the upper end of the column 56 of the lower box unit 1-52A and the upper beam 57, but the upper beam 57 alone cannot sufficiently support the column 59 of the unit 52. In the lower box unit 50A, studs 62 are installed between the upper and lower beams 55 and 57 as shown in FIG. 8, or reinforcing side beams 63 are arranged under the upper beam 57 as shown in FIG. ing.

[Problem to be solved by the invention]

As described above, in the conventional example, in order to support the setback box unit 52 on the lower box unit 50A, reinforcing members such as the studs 62 and the reinforcing side beams 63 must be placed on the lower box unit 50A. If the studs 62 are arranged in the unit 50A, a wide living space cannot be formed across a plurality of units, and if the reinforcing side beams 63 are arranged under the upper beam 57, there is a problem that the ceiling height becomes low.

Further, a roof 53 must be constructed on site to make it waterproof over the lower box unit 50A. On-site waterproofing not only requires skill, but also has the problem of not being able to sufficiently shorten the construction period.

Furthermore, when placing the box unit on a truck, the lower end of the column of the unit is supported on the truck bed via a support, but this support is attached at a specific location for the two-part and lower box units. has been done. Therefore,
In order to place the setback box unit 52 on the loading platform, this unit 52 must be placed on the other box unit 50A,
50B.

Since the dimensions between the pillars are different from that of 51, the support tool cannot be used as is, and a special jig is required.

SUMMARY OF THE INVENTION An object of the present invention is to provide a setback box unit that does not require reinforcing members such as studs on the lower box unit when supporting it on the lower box unit.
