Abstract

PROBLEM TO BE SOLVED: To provide a building unit capable of sufficiently securing natural lighting from an opening and of reducing the labor required on the building job site. SOLUTION: A building unit 33 having a frame 3 of a cubical construction containing a plurality of columns 332 and a plurality of beams 333 is formed with a storage space 34A for storing a shutter 71 at least in a part of the horizontal surface portion 34. Since the shutter 71 is stored in a shutter storage space 34A inside the horizontal surface portion 34, it becomes unnecessary to provide a shutter box for storing shutter separately on the upper exterior wall surface of the opening 52. In this way, the height dimension of the opening 52 can be made larger than the conventional dimension so that the sufficient natural lighting can be secured from the opening 52. Also, the shutter 71 can be attached to the inside of the horizontal surface portion 34 at factory in advance, so that the installing work for the shutter 71 on the job site can be performed easier.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit having a three-dimensional frame including a plurality of pillars and a plurality of beams, and having a horizontal surface portion including the plurality of beams, and the building unit. The present invention relates to a unit-type building having:

[0002]

2. Description of the Related Art Conventionally, unit-type buildings constructed by combining a plurality of rectangular parallelepiped building units manufactured in a factory at a building site have been used. Here, the building unit has a rectangular parallelepiped frame including pillars erected at the four corners, and beams connecting the upper ends of the pillars and the lower ends thereof.
At the factory, a ceiling surface material, a floor surface material, an outer wall material, and a partition wall are attached to the frame in advance, and these are transported to a construction site to construct a building. According to such a unit-type building, when a building unit is manufactured in a factory, the work conventionally performed at the building site is mostly performed at the factory, the work at the building site is significantly reduced, and high-quality The effect is that the building can be built in a short time.

In such a unit-type building, an opening formed in the outer wall surface is provided with a shutter, a shutter, and the like which cover the opening in order to prevent wind and rain and from the viewpoint of crime prevention. From the viewpoint that it is not necessary to provide a door pocket or the like on the side of the portion and a sufficient dimension in the width direction of the opening can be secured, a shutter has often been adopted as a member covering the opening. Here, as the shutter covering the opening, for example, as shown in Japanese Patent Application Laid-Open No. 10-131644, a shutter box for storing a shutter wound on an outer wall surface above the opening is provided, and a width direction of the opening is provided. It is known that rails for guiding a shutter are provided along both ends.

[0004]

However, in such a shutter, a shutter box for winding and housing the shutter must be provided on the outer wall surface above the opening, so that the size of the opening in the height direction is sufficiently large. There is a problem that cannot be secured. In particular, with respect to the opening of the part where the balcony and the like are installed on the upper floor, there is little possibility that the rainwater directly enters the opening due to the balcony and there is no need to use the shutter box as an eaves,
In such a situation, there is a demand for a structure capable of securing sufficient lighting by taking the height of the opening. In addition, in the conventional unit construction method, since the shutter is mounted on the outer wall surface, it becomes a hindrance to stringing or the like during transportation by a truck or the like, and the mounting of the shutter must be performed at the construction site, which complicates the work on the construction site. There is a problem that leads to the conversion.

An object of the present invention is to provide a building unit having a three-dimensional frame including a plurality of columns and a plurality of beams, and having a horizontal plane portion including the plurality of beams, and a building unit including the building unit. It is an object of the present invention to provide a building unit and a building unit that can secure sufficient lighting at the opening and reduce the work at the building site.

[0006]

In order to achieve the above object, a building unit according to the present invention comprises a plurality of columns 332, 352, 812 and a plurality of beams 333, 353, as described with reference to the drawings. Building units 33, 35, 81 having three-dimensional frames 331, 351, 811 including the horizontal planes 34, 36, 83 including the plurality of beams. A shutter storage space 3 for storing a shutter is provided in at least a part of the surface.
4A, 36A and 83A are formed.

Here, as a three-dimensional structure frame including a plurality of columns and a plurality of beams, for example, a frame provided with columns erected at four corners and beams connecting between upper ends and lower ends of the columns. However, the present invention can be applied to building units of various shapes as long as they have a frame capable of forming a horizontal plane portion including horizontal structural members such as beams. Also, the horizontal plane portion may be formed on the upper surface side of the building unit, may be formed on the lower surface side, and when the shutter storage space is formed on the upper surface side of the building unit, A shutter that covers an opening formed in the building unit can be stored. On the other hand, when the shutter storage space is formed on the lower surface side of the building unit, the shutter that covers the opening disposed on the lower floor side of the building unit can be stored.

According to the present invention, since the shutter is housed in the shutter housing space in the horizontal plane constituting the building unit, it is necessary to provide a shutter box for housing the shutter separately on the outer wall surface above the opening 52. Disappears.
As a result, the height of the opening can be larger than that of the related art, so that sufficient lighting of the opening can be secured.

Further, since the shutter is housed in a horizontal plane portion including the beam which is a structural member of the building unit, the shutter does not become an obstacle even if the building unit is strapped during transportation. Therefore, when assembling the building unit at the factory, the shutter can be mounted at the same time, and the work at the building site can be greatly reduced. Furthermore, if the shutter is housed in the horizontal plane on the upper surface side of the building unit, the shutter guide rails provided at both ends of the opening formed in the same building unit below the shutter can be simultaneously attached at the factory. Therefore, work on the construction site can be further reduced.

In the above, as the above-mentioned building unit, a so-called inner balcony unit 81 is considered, in which the inner space is partitioned by a partition wall including the outer wall material 82, one of which is defined as an indoor space and the other is defined as an outdoor space. The shutter storage space 83A is located on the outdoor side of the partition wall.
And it is preferable to be formed along the partition. That is, when the space inside the unit is partitioned as an indoor space and an outdoor space, as in an inner balconi unit, an opening for exiting from the indoor space to the outdoor space is formed. If the shutter housing space is formed along, it is suitable as a housing space for housing a shutter that covers this opening.

Further, as another building unit, the building unit is formed so as to protrude from the side surfaces of the frames 331, 351.
An overhanging surface portion 33D that constitutes a part of the horizontal surface portions 34, 36,
A building unit with 35C is conceivable, in which case the shutter storage space is preferably formed in this overhanging surface. Since such an overhanging surface portion is used as an outdoor floor surface such as the balcony floor 6, if the shutter storage space is formed in the overhanging surface portion, similarly to the above, an opening for exiting to the outdoor space is provided. This is suitable as a storage space for storing a shutter that covers the camera.

Further, it is preferable that receiving portions 346 and 360 for supporting the cantilever-supporting structure 73 are provided on the outdoor side of the overhanging surface portion including the shutter housing space. As described above, since the receiving portion is provided outside the overhanging surface portion, the cantilevered outdoor floor surface can be expanded to the outdoor side, so that an outdoor floor surface such as a barconi floor surface is formed more widely. can do.

When the above-described receiving portion is provided, it is preferable that reinforcing portions 345 and 359 for preventing the receiving portion from falling are formed between the shutter housing space and the receiving portion. Here, specifically, the reinforcing portion includes beams 342 and 356 disposed at the outdoor end of the projecting surface portion on which the receiving portion is provided, and a projecting surface portion for partitioning the shutter housing space in the horizontal plane portion. A plurality of steel beams 345, 359 can be installed between the beams and intermediate installation members 344, 358 installed in parallel with the beams. In this manner, since the reinforcing portion is formed on the overhanging surface portion, it is possible to prevent the receiving portion to which the cantilevered structure is joined from falling down. It can be maintained by supporting strength.

The unit-type building 1 of the present invention has a three-dimensional frame including a plurality of columns and a plurality of beams,
A horizontal surface portion including the plurality of beams is provided, and at least a part of the horizontal surface portion includes building units 33 and 35 each having a shutter housing space for housing a shutter. According to such a unit-type building, as described above, by installing the shutter in the shutter storage space in advance in the factory, the shutter can be installed together with the installation of the building unit. Can be reduced.
