Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame having pillars standing at four corners, and a ceiling beam and a floor beam interconnecting upper and lower ends of the pillars. The present invention relates to an outdoor floor-equipped building unit provided with an outer wall portion for partitioning the inside of the vehicle and an outdoor floor exposed to the outside and an indoor floor arranged indoors.

[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] By the way, a balcony may be formed on the outdoor part of a building. In a unit type building, a balcony may be formed by projecting a cantilever-supported balcony on the outer wall of the building. Since the balcony unit is cantilevered, mounting work at a construction site becomes complicated. For this reason, a balcony may be formed using an outdoor floor-equipped building unit in which a part of the floor of the above-mentioned building unit is an outdoor floor such as a balcony (see Japanese Patent Application No. 11-1897).

[0004] The outdoor floor of a building unit with an outdoor floor and the indoor floor arranged indoors are separated by an outer wall material provided along the boundary. The outer wall material is supported by studs and intermediate beams assembled in a square frame along the boundary. These studs and intermediate beams are joined to the framework of the building unit with outdoor floor. Here, when a horizontal external force is applied to the outer wall surface of the building unit with the outdoor floor, the studs and intermediate beams assembled in a square frame shape may be deformed. For this reason, it is necessary to reinforce the joint between the stud and the intermediate beam.

[0005]

In such a building unit with an outdoor floor, when the studs and the intermediate beams are joined to the frame by pin joints, rigidity is insufficient. Therefore, rigid joints are used. In this case, there is a problem that joining of the studs and the intermediate beams to the skeleton is extremely troublesome.

An object of the present invention is to provide a building unit with an outdoor floor which can ensure sufficient rigidity and is easy to manufacture.

[0007]

The present invention will be described with reference to the accompanying drawings. Referring to the drawings, a pillar 41 is provided upright at four corners, and a ceiling beam 42 interconnecting between upper and lower ends of these pillars 41 is provided. A frame 40 having a floor beam 43 is provided.
0, and an outer floor (for example, a balcony floor 30A) that is exposed outdoors,
An indoor floor-equipped building unit 20B in which an indoor floor 30B disposed inside a room is provided, and a first stud 47A connecting an intermediate portion of the ceiling beam 42 and the floor beam 43 to both sides of the outer wall portion 31. The upper and lower ends of the first studs 47A are respectively connected to a middle ceiling beam 46A and a middle floor beam 46A.
B, the ceiling middle beam 46A and the floor middle beam 46B
Between the ceiling middle beam 46A and the floor middle beam 46B
A pair of second studs 47B are provided to connect the middle portions of the first and second studs 47A and 47B, and the ends of the first and second studs 47A and 47B that are different from each other are connected to each other by a diagonal member 31C. And According to the present invention, a triangular truss is formed at both ends of the outer wall portion by the first stud, the second stud, the intermediate ceiling beam, the intermediate floor beam, and the diagonal members.
Sufficient rigidity is secured in the building unit with outdoor floor against horizontal external force. Therefore, it is possible to secure sufficient rigidity with a simple reinforcing structure in which the second studs are added and the first studs and the second studs are connected with diagonal members, and these connections are also joined by pin joining. The production becomes easy.

In the above, the first and second studs 47
It is preferable that an outer wall material 31B that covers the opening 31D is provided in the opening 31D formed between A and 47B. In this way, if the outer wall material is provided so that the above-mentioned diagonal member is not visible from the outside of the building, the appearance of the building can be improved. In addition, if the outer wall material is a book wall which can be moved in the horizontal direction, it can be easily attached to the framework of the building unit with an outdoor floor, and this also facilitates the manufacture of the building unit with an outdoor floor. .

It is desirable that the joint between the end of the second stud 47B and the intermediate ceiling beam 46A and the intermediate floor beam 46B is a pin joint. Here, as the pin bonding, a bonding method using a bolt, a rivet, or the like can be employed. This makes it possible to easily join the second studs, which also facilitates the production of the outdoor floor-equipped building unit.

Further, it is preferable that the outer wall portion 31 is provided with a sweeping window 31A for moving back and forth between the outdoor floor 30A and the indoor floor 30B. In this way, the sweep window can be used as a passage to the indoor space for drying laundry, placing plants, sunbathing, etc. on the outdoor floor. Can be used effectively.

Further, it is desirable that the diagonal member is a tension brace 31C which secures rigidity by facing tension. In this way, even if a member having a relatively small cross section is employed, sufficient rigidity is ensured, so that the handling of the diagonal member is facilitated, and therefore, the mounting of the diagonal member is also simplified. Further, if a turn buckle is provided in the tension brace, for example, by tightening the turn buckle, the rigidity of the skeleton can be easily adjusted, and the rigidity can be easily improved to an appropriate rigidity.
