Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overhang type unit building in which a part of an upper floor building is overhung with respect to a lower floor building unit.

[0002]

2. Description of the Related Art As a unit building constructed by combining a plurality of factory-produced rectangular parallelepiped building units at a construction site, as shown in FIG. 3, a rectangular parallelepiped lower floor building unit 1 and this lower floor building unit An overhang type unit building including a rectangular parallelepiped upper floor building unit 3 having an overhang portion 2 installed on the building unit 1 and extending outwardly from the lower floor building unit 1. Are known (see JP-A-63-147036, JP-A-4-44547, JP-A-4-237739, etc.).

In this overhang type unit building, the floor area of the upper-floor building unit 3 can be made larger than that of the lower-floor building unit 1, while the overhang portion 2 is downward. It has the drawback of being easily bent. In order to eliminate this defect, the upper floor building unit 3
The cross-sectional shape of the floor beam 9 may be increased, but this requires changing the unit size, the accommodation, and the like, and a standard unit cannot be used.

Therefore, conventionally, as shown in FIG. 4, the pillar 2 is provided directly below the two pillars 7c and 7d of the overhang portion 2 of the upper floor building unit 3 installed on the lower floor building unit 1.
0, and an overhang type unit building having a structure in which the support 20 supports the load of the overhang portion 2 of the upper floor building unit 3, or a lower floor building unit as shown in FIG. 1 ceiling beam 6 to upper floor building unit 3
An overhang type unit building having a structure in which a projecting member 21 for receiving the two pillars 7c and 7d of the overhang portion 2 is used. A cane 22 is obliquely provided between the tip of the projecting member 21 and the columns 4c and 4d of the lower floor building unit 1.

[0005]

However, in the overhang type unit building shown in FIG. 4, the overhang is determined by the pillars 20 which are determined by the positions of the pillars 5c and 5d of the overhang part 2. -There is a problem that the space below the hang portion is uniformly limited, and the space cannot be effectively used. Further, in the overhang type unit building shown in FIG. 5, since it is necessary to separately manufacture the above-mentioned overhanging member and attach this to the ceiling beam of the lower-floor building unit by welding or the like, it is troublesome and costly. In addition to a large amount of stress, stress tends to concentrate on the mounting portion due to welding or the like, and a strength problem remains.

The present invention has been made in view of the above circumstances, and it is possible to effectively utilize the space below the overhang portion, and at the same time, to improve the workability, the cost and the strength. -The purpose is to provide a bar-hung unit building.

[0007]

To achieve the above object, the present invention is directed to a lower floor building unit in the shape of a rectangular parallelepiped, and a lower floor building unit installed on the lower floor building unit and extending outward from the lower floor building unit. In an overhang type unit building including a rectangular parallelepiped upper floor building unit having an overhang portion, the upper floor building unit overhangs in the longitudinal direction of the ceiling beam of the lower floor building unit. -It is characterized in that the extension beam portion for supporting the bar hang portion is continuously formed integrally.

[0008]

According to the overhang type unit building having the above-mentioned structure, the load of the overhang portion of the upper floor building unit passes through the extension beam portion of the ceiling beam of the lower floor building unit to the lower floor building unit. Therefore, the overhang portion is prevented from being bent. Further, since the extension beam portion is integrally formed continuously in the longitudinal direction of the ceiling beam of the lower-floor building unit, a conventional overhang in which a column is provided directly below the overhang column. Unlike the conventional unit building, the space below the overhang portion can be effectively used and the overhanging unit of the related art in which a projecting member is separately provided on the ceiling beam of the lower floor building unit. Unlike a building, it can improve workability, reduce costs, and improve strength.
