Abstract

PROBLEM TO BE SOLVED: To provide a unit type building which secures a sufficient floor area of a habitable room and which is easy in an erection work. SOLUTION: In the unit building 1, a main entrance unit 30 is provided with a main entrance earthen floor 30B along the whole length of the shorter side of a main entrance earthen floor 30B of which the shorter side is the half of that of first and second floor building units 10, 20 or smaller than that and which is lower than other floor faces, and which is formed separately from the first floor building unit 10 and the second floor building unit 20 of which the longer side and the shorter side of a rectangular form are set in a specified size respectively. Since a sufficient habitable floor area can be secured and the main entrance earthen floor 30B is provided along the whole length of the shorter side of the main entrance unit 30, the skeleton of the main entrance unit 30 is not complicated. Hence, the erection work of the unit building 1 is facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit-type building formed by combining a plurality of building units each having a rectangular planar shape having long sides and short sides.

[0002]

2. Description of the Related Art Conventionally, unit-type buildings formed by combining a plurality of building units manufactured in a factory at a building site have been used. The building unit is usually composed of pillars erected at the four corners, and ceiling beams and floor beams interconnecting the upper and lower ends of these pillars, and has long sides and short sides having different lengths. It has a rectangular parallelepiped frame having a rectangular planar shape. Floor materials, wall materials, and other necessary equipment members are attached to this framework in advance at a factory. According to such a unit-type building, a floor surface material or the like is attached to the building unit in advance. Therefore, there is an advantage that the construction period at the construction site can be significantly reduced.

[0003] When a unit-type building is provided with a front-to-rear area constituting a front door, a part of a normal building unit having a predetermined size is used as shown in Japanese Patent Application Laid-Open No. 9-125523. are doing.

[0004]

In such a unit-type building, since the space between the entrances is interrupted at an intermediate position in the short side direction of the building unit, the frame of the building unit becomes complicated, and the building unit has a complicated structure. There is a problem in that the manufacturing operation and, consequently, the building operation of the unit building become complicated. On the other hand, in order to avoid complication of the frame, for example, it is conceivable to provide a large entrance soil over the entire length of the short side of a normal building unit. There is a problem that it is difficult to secure a sufficient living floor area.

An object of the present invention is to provide a unit-type building in which a sufficient floor area of a living room is secured and construction work is easy.

[0006]

The present invention will be described with reference to the drawings. The present invention is formed by combining a plurality of building units 10, 20, 30 each having a rectangular planar shape having long sides and short sides. Unit building 1 in which a long side and a short side of a rectangle are set to predetermined dimensions (for example, a first-floor building unit 10 and a second-floor building unit 20), and shorter than the normal building unit. An auxiliary building unit (for example, an entrance unit 30) having a reduced side dimension, and at least a part of the auxiliary building unit is provided with an entrance soil space 30B lower than other floors over the entire length of the short side. It is characterized by having been done.
According to the present invention as described above, since the entrance space is provided in the auxiliary building unit separate from the normal building unit, it is possible to secure a sufficient living floor area, and to reduce the total length of the short side of the auxiliary building unit. Since we will set up the entrance to the entrance,
The framework of the auxiliary building unit is not complicated, thereby facilitating construction work of the unit-type building.

In the above description, the above-mentioned auxiliary building unit (for example, the entrance unit 30) is composed of pillars 32 erected at four corners, a ceiling beam 33 and a floor connecting the upper ends and lower ends of these pillars 32 to each other. One of a pair of long-side floor beams 34A, which has a rectangular parallelepiped frame 31 including a beam 34 and forms a long side of the rectangular parallelepiped, has a portion corresponding to the position of the entrance wall 30B omitted. Floor beams (for example,
Studs 37 extending toward the corresponding ceiling beam 33A are provided at the ends of the first floor beam member 341A and the second floor beam member 341B), and the corresponding other long side floor beam 3 is provided.
Preferably, an intermediate beam 38 extending toward 42 is provided. At this time, the above-mentioned omitted portion is between the studs 47 and the columns 42 of a part of one long-side floor beam 44A,
A portion surrounded by the intermediate beam 48, a part of the other long-side floor beam 44A, and one of a pair of short-side floor beams 44B constituting the short side of the rectangular parallelepiped may be the entrance soil space 40B.

Further, the above-mentioned auxiliary building unit (for example, the entrance unit 50) has columns 52 standing at four corners.
And a frame 51 having a ceiling beam 53 and a floor beam 54 interconnecting the upper end and the lower end of these pillars 52. The ceiling beam 53 includes a short side ceiling beam 53B and a long side ceiling beam 53A. The floor beams 54 include both the short-side floor beams 54B and the long-side floor beams 54A, and the short-side floor beams bridged between one ends of the pair of long-side floor beams 54A are omitted. It is preferable that a portion surrounded by the pair of long-side floor beams 54A and the short-side floor beams 54B bridged between the other ends of the pair of long-side floor beams 54A be the entrance soil 50B.

In addition, the aforementioned auxiliary building unit (for example,
The entrance unit 60) includes a frame 61 having columns 62 erected at four corners, and a ceiling beam 63 and a floor beam 64 interconnecting between upper ends and lower ends of the columns 62,
The ceiling beam 63 includes both the short side ceiling beam 63B and the long side ceiling beam 63A, and the floor beam 64 includes the short side floor beam 64.
B and the long side floor beam 64A are included, and the long side floor beam bridged between one ends of the pair of short side floor beams 64B is omitted, and is bridged between the other ends of the pair of short side floor beams 64B. It is desirable that a portion surrounded by the long side floor beam 64A and the pair of short side floor beams 64B be the entrance soil space 60B.

As described above, if a plurality of auxiliary building units having different positions and sizes between the entrance soils are used, the entrance can be easily selected by selecting the unit type building in accordance with the shape and orientation or the desired entrance structure. It is possible to improve the appearance of the unit-type building as well as to provide the unit-type building.
