Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit building.

[0002]

2. Description of the Related Art A unit construction method for constructing a unit building in a short time by transporting a plurality of box-shaped building units manufactured in advance in a factory to a construction site and assembling a plurality of building units at the construction site. It has been done conventionally.

In such a unit construction method, an upper-floor building unit (upper-floor unit) may be installed overhanging (overhanging) on a lower-floor building unit (lower-floor unit).

For example, in Japanese Patent Laid-Open No. 6-212704, an upper unit is overhung on a lower unit, and a separate overhanging roof is locally provided below the overhang portion of the upper unit. It is retrofitted to form a parking space in the lower space.

[0005]

However, in the unit building of the above publication, since a separate overhanging roof is additionally attached to the lower part of the overhang portion of the upper floor unit, there is a problem that it takes a lot of time for installation on site. There is.

Further, the above-mentioned overhanging roof has a problem that the upper space cannot be used as a living space.

[0007] Further, since the device for overhanging the upper floor unit or attaching the overhanging roof to the upper floor unit is carried out within the range of one unit, it is not related to the adjacent units. There is no problem, and there is the problem of lacking plan support.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to provide a unit building capable of reducing the number of on-site installation steps and increasing the plan adaptability.

[0009]

In order to solve the above problems, according to the invention as set forth in claim 1, in a unit building in which an upper floor unit is installed overhanging on a lower floor unit, It features a unit building in which an overhang expansion member is integrally provided in the overhang portion of the floor unit.

According to the first aspect of the present invention thus constructed, the overhang expanding member is integrally provided in the overhang portion of the upper floor unit, so that the expanded overhang can be accurately manufactured at low cost. In addition, it is possible to shorten the construction period by reducing the number of on-site installation steps. In addition, the space under the expanded overhang can be effectively used as a parking space, a bicycle parking space, an entrance approach, a garbage storage space, and the like.

The invention according to claim 2 is characterized by the unit building according to claim 1, wherein the overhang expanding member is a cantilever balcony.

According to the second aspect of the present invention thus constructed, the cantilever balcony is used as the overhang expanding member, so that the upper space of the overhang can be effectively used as a living space such as a balcony. .

According to the third aspect of the present invention, in a unit building in which the upper floor unit is installed overhanging the lower floor unit, at least two or more upper floor units are installed overhanging. The unit building includes a balcony unit and a living room unit in which the upper floor units are arranged adjacent to each other, and the outer wall surfaces of the balcony unit and the living room unit are aligned on the same plane.

According to the third aspect of the present invention having such a structure, the outer wall surfaces of the overhung balcony unit and the living room unit are aligned on the same plane, so that a neat appearance can be obtained. . Also, the balcony floor area can be expanded by overhanging the balcony unit. Furthermore, by overhanging the balcony unit and the living room unit in the adjacent state, a wide lower space can be obtained, and the lower space can be effectively used.

In a fourth aspect of the present invention, in a unit building in which an upper floor unit is overhanged on a lower floor unit, at least two upper floor units are overhanged. The unit building is characterized in that the overhang portions of the upper floor unit are arranged in a discontinuous state, and the overhang portions are connected by an overhang connecting member.

According to the fourth aspect of the present invention having the above-mentioned structure, since the overhang portions in the discontinuous state are connected by the overhang connecting member, a wide lower space can be obtained and the lower space can be formed. In addition to being effectively utilized, a wide upper space can be obtained and the upper space can be effectively utilized. In addition, a variety of appearances can be obtained.

First, the structure will be described. The unit building 5 is constructed by overhanging the upper floor units 3 and 4 on the lower floor units 1 and 2 and installing them.

In the first embodiment, the unit building 5 includes at least two lower floor units 1 and 2,
And at least two or more overhung upper floor units 3, 4.

Then, outside the overhang portions 6 and 6 of the upper floor units 3 and 4, the overhang expansion members 8 and 8 are integrally provided in advance at the factory.

The overhang expanding members 8 and 8 are, for example, the pouch 10 shown in FIGS. 1 and 2, the balcony 11 shown in FIG. 3, and the pouch 10 shown in FIG.
And a balcony 11 or an eaves panel, an entrance step, etc., which are not particularly shown.

In order to support the overhang portions 6 and 6 of the upper floor units 3 and 4 and the overhang expansion member 8, the lower floor units 1 and 1 as shown in FIGS.
The common overhanging member 12 extended in the overhang direction from the joining portion of the upper floor unit 2 and the upper floor units 3 and 4 is used. In this way, by supporting the overhang portions 6, 6 and the overhang expanding member 8 by using the common overhanging member 12, the mounting accuracy and the mounting strength of the overhang portions 6, 6 and the overhang expanding member 8 can be improved. It is possible to improve the structure and simplify the mounting structure. In addition,
In FIG. 5, reference numeral 9 is an eaves ceiling material.

Alternatively, as shown in FIG. 6, the lower floor units 1 and 2 are connected to a steel frame 15 having a box frame structure.
16 is preliminarily manufactured as a twin unit 17 in which two pieces are connected to each other in a factory, and two outer columns and floor beams of the steel frame 16 on the overhang side of the twin unit 17 are set as temporary columns 18 and temporary beams 19, As shown in FIG. 7, after the upper floor units 3 and 4 are installed on the twin unit 17 in the field, the temporary columns 18 and the temporary beams 19 are removed, so that the overhang portions 6 and 6 of the upper floor units 3 and 4 are removed. Also, the overhang expansion member 8 may be supported. By doing this, it becomes possible to unitize the entire overhang part and produce it at the factory,
Even the finishing of the eave ceiling and the outer wall of the overhang portions 6, 6 and the overhang expansion member 8 can be accurately produced in the factory. Further, in this case, since a very large supporting strength can be obtained, it is possible to eliminate the overhang expanding member 8 and expand the overhang portions 6 and 6 themselves to the range where the overhang expanding member 8 is provided. It is possible.

Next, the operation of the first embodiment will be described.

By integrally providing the overhang expanding members 8 and 8 in the overhang portions 6 and 6 of the upper floor units 3 and 4 in advance at the factory, the expanded overhang can be produced accurately and inexpensively. At the same time, the number of on-site installation steps can be reduced and the construction period can be shortened. Also,
The lower space of the expanded overhang can be effectively used as a parking space, a bicycle parking space, an entrance approach, a garbage storage place, etc.

Also, by overhanging a plurality of upper floor units 3 and 4 and attaching the overhang expanding members 8 to them, respectively, a wide lower space and a wide upper space usable as a living space can be obtained. At the same time, it is possible to increase the ability to support the plan.
