Abstract

PROBLEM TO BE SOLVED: To provide a building unit which permits a floor surface to be installed consecutively and enables an improvement in appearance. SOLUTION: Horizontal frame members 62 and 63 forming a floor overhang surface part 60 and a peripheral frame member 61 with a mounting piece 65 are composed of a material lower in height than a floor beam 44. A long inner balcony is formed by adjacently disposing the two building units along a long- side direction so that the members 63 can face each other. A step can be made small in a boundary section between the building units 20B and 20C, for the purpose of permitting a balcony floor 30A to be installed consecutively and enabling the appearance to be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rectangular parallelepiped which bears the structure of a building having pillars erected at four corners and a ceiling beam and a floor beam interconnecting between upper ends and lower ends of the pillars. And a projecting portion that extends horizontally from the lower end of the base and constitutes an outdoor floor surface.

[0002]

2. Description of the Related Art Conventionally, unit-type buildings have been diversified in response to a user's request and the like. For example, when forming an inner balconi or the like, a column standing at four corners and an upper end and a lower end of the column are required. A cuboid base that bears the structure of the building with ceiling beams and floor beams that interconnect the
There is a case where a building unit configured to include a projecting surface portion that extends horizontally from a lower end of the base and forms an outdoor floor surface is used, and a unit-type building combining these is also built (Japanese Patent Application See, for example, Hei 11-1897).

[0003] Here, an overhanging surface portion constituting an inner floorconi or the like as an outdoor floor surface is provided with an outer peripheral frame material forming a peripheral edge of the inner balconi. The height of the outer frame material is substantially the same as the height of the floor beam at the base.

[0004]

However, when a plurality of building units having an inner balcony are used and the inner balcony is formed continuously along the longitudinal direction,
Since a large step occurs due to the outer peripheral frame material disposed at the boundary between the building units, there is a problem that the outdoor floor surface is not continuous, it is difficult to walk, and the appearance of the balcony is impaired.

[0005] It is an object of the present invention to provide a building unit in which the floor can be made continuous and the appearance can be improved.

[0006]

The present invention will be described with reference to the accompanying drawings. Referring to the drawings, a pillar 42 standing at four corners and a ceiling beam 43 and a floor beam interconnecting the upper end and the lower end of the pillar 42 are interconnected. The building unit 20 </ b> B includes a rectangular parallelepiped base 40 that has the structure 44 and bears the structure of the building, and a projecting surface 60 that extends horizontally from the lower end of the base 40 and forms an outdoor floor surface. In addition, the overhang surface portion 60 has an outer peripheral frame material 61 that forms the periphery of the outdoor floor surface.
1 is characterized in that it is made of a member having a smaller height dimension than the floor beam 44. Here, inner balconies or the like can be adopted as the outdoor floor surface. According to such an aspect of the invention, by forming the outer peripheral frame member forming the overhanging surface portion with a member having a smaller height dimension than the floor beam, for example, two building units are arranged so that the outer peripheral frame members face each other. When the outdoor floor is formed continuously along the longitudinal direction and the outdoor floor surface is formed continuously, it is possible to reduce the level difference at the boundary between the building units. Thereby, it becomes possible to make an outdoor floor surface continuous, and it becomes possible to improve an external appearance.

[0007] In the above, the box-shaped extension portion 50 protruding from the side surface of the base 40 is provided, and the beam members (for example, the horizontal construction members 52, 53, 54) constituting the extension portion 50 are provided.
Is preferably approximately the same height as the floor beam 44.
At this time, the overhang surface portion is provided at a portion sandwiched between the base portion and the extension portion. In this way, it is possible to reduce the level difference at the boundary between the base and the extension, so if the interior of the extension is an interior space that is continuous with the interior of the base, a large continuous indoor floor It is possible to obtain.

Further, a ceiling overhanging surface portion 70 which extends horizontally from the upper end of the base portion 40 is provided, and the overhanging surface portion 60 and the ceiling overhanging surface portion 70 are connected to each other by a connecting member (for example, a vertical member 81).
Are preferably connected to each other. This makes it possible to increase the supporting strength of the overhanging surface portion by the connecting member, thereby increasing the rigidity of the building unit.

Further, between the vicinity of the end of the connecting member (for example, the vertical member 81) and the vicinity of the end of the pillar 42 which is obliquely inclined near the end, during transportation of the building unit 20B. It is desirable to provide a brace 82 that connects the vicinity of the end of the connecting member and the vicinity of the end of the pillar 42 to each other. This makes it possible to easily prevent the building unit from being deformed by the external force in the horizontal direction due to the brace, so that the building unit does not need to have a complicated structure. Can be easily performed.
