DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balcony installed in a residential building or the like.

[0002]

2. Description of the Related Art Since the above-mentioned balcony is installed outdoors in a house or the like and is almost exposed to the rain, sufficient waterproofing and drainage work are required. FIG. 11 shows a conventional example of such a balcony. This balcony 30 includes a supporting member 33 that is cantilevered outward from a fixing member (H steel) 32 on the building body 31 side, and the supporting member. The balcony main body 34 supported from below by 33.

The balcony body 34 includes a floor plate 37 stretched on the support member 33 via a floor base plate 35 and joists 36, and a waist provided between steel columns (not shown) provided at the tip of the support member 33. wall
38, and a waterproof sheet 39 on the entire upper surface of the floorboard 37.
An artificial turf 40 is stretched through. Reference numeral 41 is a drainage groove arranged on the floor surface of the balcony main body 34, and in this example, by disposing the floor plate 37 away from the waist wall 38, the drain groove is arranged along the root of the waist wall 38. ing. The waterproof sheet
39 is extended along the inner surface of the drainage groove 41, whereby the inside of the drainage groove 41 is waterproofed.
Reference numeral 42 denotes a drain pipe, which is connected between the bottom surface of the drainage groove 41 and a vertical pipe 43 provided on the wall surface of the lower building of the building body 31.

Further, the waterproof sheet 39 is folded back up along the outer wall surface of the building body 31, and a long pressing member 44 is attached and sealed from the outside of the upper edge of the rising portion. By doing so, the root side of the balcony 31
The waterproof treatment on the building body 31 side has been carefully done.

[0005]

By the way, in the cantilever type balcony 30 as shown in FIG. 11, the difference in the vibration characteristics between the building body 31 and the balcony 30 is large,
The waterproofness at the connection between the building body 31 and the balcony body 34 is particularly important. However, in the above conventional technique, the connection between the building body 31 and the balcony body 34 is completely waterproofed by the waterproof sheet 39 and the pressing member 44 that seals the waterproof sheet 39. Due to fatigue caused by the live load on the 30 and the like, the waterproof sheet 39 that seals the connection portion is likely to be cracked, and rainwater that has entered through the cracks may corrode the structural materials inside the building.

Further, the sealing of the rising portion of the waterproof sheet 39 with the pressing member 44 itself requires a lot of construction work, which causes an increase in construction man-hours. On the other hand, in view of the shortage of workers and the soaring construction costs in recent years, there is a strong tendency for the constituent members of the house such as the balcony 30 to be unitized as much as possible to reduce the construction labor on site.

However, in the above-mentioned conventional technique, since the connecting portion between the building body 31 and the balcony body 34 is continuously covered with the waterproof sheet 39, in particular, the building body 31 having a terrace (see FIG. 2). ), The floor surface of the balcony main body 34 cannot be finished unless the balcony 30 is attached to the building main body 31 side, which naturally limits the unitization of the balcony 30. It was

In view of the above situation, the present invention improves the waterproofness at the connection portion of the balcony when installing the balcony in the building regardless of the difference in the vibration characteristics of the structure, and saves the construction work at the construction site. The purpose is to significantly reduce.

[0009]

In order to achieve the above object,
The technical means taken by the present invention comprises a support member 4 projecting outward from the building body 2 and a balcony body 5 supported from below by the support member 4, and drainage is provided on the floor surface of the balcony body 5. In the balcony provided with the groove 16, the drainage groove
16 is extended along the connection between the balcony main body 5 and the building main body 2, and the floor finishing material 11 on the balcony main body 5 side and the exterior finishing material 21, 26, 27 on the building main body 2 side are the drainage grooves. It is connected through an expansion joint 18 configured in 16.

[0010]

[Operation] Since the expansion joint 18 formed in the drainage groove 16 absorbs the vibration or the like generated in the balcony 1, the balcony main body 5 is affected by the vibration or the like as in the conventional case.
There is no possibility that the waterproof property of the connection part of the above will be impeded, and it is not necessary to carefully perform waterproofing work on the connection part of the balcony main body 5.

Further, since the drainage groove 16 is provided along the connecting portion of the balcony main body 5, and the expansion joint 18 is configured in the drainage groove 16, the building main body is completed even after the balcony 1 is finished to the floor. It can be installed on the 2 side, and the balcony 1 can be unitized almost completely.
