DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balcony unit mounting structure for mounting a balcony unit provided with an eaves gutter on a living room unit.

[0002]

2. Description of the Related Art Conventional unit buildings are shown in FIGS.
As shown in FIG. 2, at least two or more steel-frame lower room units (building units) 1 are juxtaposed, and an upper-floor room unit 2 is installed on one of the lower room units 1. A balcony unit 3 is installed on a lower shed unit 1 (see FIG. 11). 1a is a ceiling frame of the lower house unit 1, 3a
Is a floor frame of the balcony unit 3, 4 is a girder beam of the ceiling frame 1a, and 5 is a balcony beam of the balcony unit 3.

In such a configuration, the girder beam 4 and the balcony beam 5 are formed from channel steel as shown in FIG. The girder beam 4 has a flange 4a, and the balcony beam 5 has a flange 5a. Moreover, the flanges 4a and 5a of the girder beam 4 and the balcony beam 5 are fixed with bolts (not shown) at the construction site.

[0004]

By the way, in such a balcony unit 3, the floor plate 6 on the floor frame 3a is located at the opposite end (eave tip) 6b from the end 6a on the upper floor living room unit 2 side. In general, rainwater flows down from the end (on the water) 6a to the end (under the water) 6b. In addition, it is common to install the eaves gutter 7 at this end (under water) 6b.

However, the lower house unit 1 and the balcony unit 3 are structured such that the flange 4a of the ceiling frame and the flange 5a of the floor frame 3a are fixed with bolts at the construction site. For this reason, the flanges 4a and 5a cannot be fixed with bolts in a state where the eaves gutter 7 is assembled. As a result, the floor frame 3a with the eaves gutter 7 assembled at the factory cannot be transported to a construction site, and the floor frame 3a cannot be assembled with the ceiling frame 1a.

In view of the above, the present invention provides a method of mounting a balcony unit in which a lower house unit and a balcony unit can be easily assembled at a construction site even if such an eaves gutter is previously assembled to a floor frame of a balcony unit. It is intended to provide a structure.

[0007]

In order to achieve this object, the invention according to claim 1 comprises a floor frame, a balcony pillar and a handrail wall, and the eaves along one side of the balcony floor under the water. In a balcony unit mounting structure in which a balcony unit to which a gutter is mounted is provided on a steel-framed living room unit having a ceiling frame, a water surface of the balcony floor is first fixed to beams of the ceiling frame and the floor frame. The balcony floor is provided with a balcony unit mounting structure in which the stairs of the living room unit column and the balcony column are mounted by the second fixing means. According to this configuration,
The other side of the balcony floor, which is above the water, is attached to the girder flange with the first fixing means, and one side of the balcony floor is attached to the capital of the unit pillar with the second fixing means. When one side of the floor is attached to the capital of the unit pillar by the second fixing means, the eaves gutter does not disturb the floor even if the gutter is previously assembled to the floor of the balcony unit.

The invention according to claim 2 is characterized in that the second fixing means is a column joint bolt penetrating a balcony column and fixing the balcony floor portion to a column capital of the living room unit column. According to this configuration, the floor is fixed to the upper end of the unit column by the column joint bolt, so that the floor can be easily fixed to the column capital.

According to a third aspect of the present invention, there is provided a capital joint projecting portion projecting upward from the capital of the living room unit column,
The balcony floor is provided with a capital joint recess which fits into the capital joint protrusion, and the capital joint bolt is screwed to the capital joint protrusion. According to this configuration, the positioning of the balcony unit and the living room unit can be easily performed by aligning the capital joint joint recess of the balcony unit with the projection of the capital joint of the living room unit.

According to a fourth aspect of the present invention, a box-shaped capital joint having a mounting opening that opens upward is integrally provided on the balcony floor, and the bulge protrudes upward from the bottom wall of the capital joint. A protrusion is formed, and the capital joint recess is formed in the bulging protrusion. According to this configuration, the capital joint recess can be easily formed.
