Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a balcony with a waterproof sheet structure.
[0002]
[Prior art]
In general, a balcony structure in which a waterproof sheet is coated on a balcony base is known.
[0003]
Conventionally, as shown in FIG. 5, such a balcony a is configured by laying a waterproof steel plate unit d in which a waterproof sheet c is bonded to a formed steel plate b on a balcony base e. At this time, the parapet part f on the periphery of the balcony a is provided with an outer wall panel i on the outside of the parapet frame h provided on the beam g, and a waterproof steel plate unit d is provided on the inner side of the parapet frame h. The headboard j was covered from the upper side of the panel i and the waterproof steel plate unit d, and the handrail wall k was constructed on the headboard j.
[0004]
[Problems to be solved by the invention]
However, in the case of the balcony a in which the parapet frame h is provided on the beam g as in the conventional case, the portion of the outer wall panel i under the handrail wall k becomes large. Therefore, if heavy rain that cannot be treated by the drainage channel m of the balcony a or the drainage channel m becomes clogged, rainwater will accumulate on the balcony a. Therefore, the drain pipe n must be provided through the parapet frame h and the outer wall panel i from the waterproof steel plate unit d to the portion of the outer wall panel i below the handrail wall k, which makes the construction troublesome.
[0005]
Moreover, even if the drain pipe n is provided, there is a concern that if the drain pipe n is clogged, rainwater collected on the balcony a may enter the room through the discharge window o. In recent years, in particular, it has been attempted to make the stride height p of the sweeping window o facing the balcony a as small as possible so as to be barrier-free. Therefore, when rainwater accumulates on the balcony a, it becomes easy to enter the room. .
[0006]
Furthermore, since the portion of the outer wall panel i under the handrail wall k becomes large, there arises a disadvantage that the handrail wall k becomes small on the appearance of the balcony a.
[0007]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a balcony structure capable of reducing the outer wall portion under the handrail wall without providing a drain pipe.
[0008]
[Means for Solving the Problems]
The balcony structure of the present invention for solving the above problems is a balcony structure in which a waterproof sheet is coated on a balcony base, and the parapet portion on the peripheral edge of the balcony base is handrailed with an appropriate interval. Wall fixing members are fixed, and these handrail wall fixing members are covered with a waterproof steel plate at a height lower than the straddle height of the sweep window, and the end of the waterproof steel plate is a parapet around the outer wall of the balcony. It is fixed to the outer wall of the balcony by the parting material, and the parapet parting material is partly fixed to the outer wall of the balcony with the end of the waterproof steel plate, and between the waterproof steel plate at a part other than this fixing part, A gap is formed.
[0009]
With this configuration, when a large amount of rainwater accumulates on the balcony, the rainwater overflows from the parapet portion, passes through the gap between the parapet parting material and the waterproof steel plate, and flows down along the outer wall of the balcony.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0011]

An end portion of the waterproof steel plate 5 is fixed to the balcony outer wall 7 by a parapet parting material 6.
[0013]
The balcony base 2 is configured by placing an ALC plate 22 on a beam 21.
[0014]
The waterproof sheet unit 3 is configured in a unitized state in which a non-combustible board 32 and a waterproof sheet 30 are pasted on a polystyrene foam 31. Among these, the polystyrene foam 31 is provided with an inclined gradient so that a downward gradient is obtained from the sweep window 8 side to the handrail wall 9 side in the construction state.
[0015]
As shown in FIG. 4, the handrail wall fixing member 4 includes a parapet base portion 41 that constitutes a base portion of the parapet portion 11 on the beam 21 exposed to the parapet portion 11 on the periphery of the balcony base 2, A handrail wall frame portion 42 that extends on the parapet base portion 41 and constitutes the core material of the vertical rail 91 of the handrail wall 9. A plurality of handrail wall fixing members 4 are fixed to the beam 21 exposed at the parapet portion 11 on the periphery of the balcony base 2 by bolts and nuts 43 with appropriate intervals.
[0016]
The waterproof steel plate 5 is overlapped with the waterproof sheet unit 3 inside the parapet portion 11 of the balcony 1, covers the parapet base portion 41 of the handrail wall fixing member 4, and is provided to the end surface of the balcony outer wall 7. 51, the caps steel plate 52 provided from the end surface of the balcony outer wall 7 to the surface, and a waterproof sheet 53 covered from the waterproof sheet unit 3 to the caps steel plate 52. The waterproof base rail 51 is fixed to the parapet base portion 41 of the handrail wall fixing member 4 together with the waterproof sheet unit 3 with screws 54 at the rising portion inside the parapet portion 11. The waterproof base rail 51 is fixed to the parapet base portion 41 of the handrail wall fixing member 4 with screws 54 at the top end surface of the parapet portion 11, and with screws 55 to the end surface of the balcony outer wall 7 together with the headboard steel plate 52. Fixed. In this fixed state, the waterproof sheet 53 is covered from the floor surface of the waterproof sheet unit 3 to the top end surface of the parapet part 11 through the rising part inside the parapet part 11. With this waterproof steel plate 5, the balcony 1 is waterproofed continuously from the waterproof sheet unit 3 inside the parapet 11 to the balcony outer wall 7 outside the parapet 11. In this fixed state, the handrail wall fixing bracket 4 having the parapet base portion 41 set in advance low is used so that the waterproof steel plate 5 is lower than the stride height H of the sweep window 8. .
[0017]
