Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to a balcony attached to the outer wall of a house.

[Background technology]

Conventionally, as shown in Fig. 4, a beam cover 3 made of a vinyl chloride steel plate having an approximately inverted U-shaped cross section is placed over a beam 1 made of a galvanized steel plate, and is placed on the outdoor side of the beam 1. The upper end of the decorative curtain board 4 is brought into contact with the side surface of the beam cover 3, and the space between the decorative curtain board 4 and the beam cover 3 is waterproofed with a sealant 5, and the floor provided around the inner circumference of the beam 1 is The end of the waterproof board 6 is brought into contact with the side surface of the beam cover 3, and the space between the end of the floor waterproof board 6 and the beam cover 3 is waterproofed with the sealant 7. Therefore, the waterproofing around the beam 1 is performed solely by the sealants 5 and 7 at the two locations mentioned above, and the outer sealant 5 loses its flexibility, shrinks, and peels off. Then, rainwater etc. enters between the decorative curtain board 4 and the beam cover 3,
Due to capillarity, etc., the water penetrates between the beam cover 3 and the beam 1 and penetrates below the floor waterproof board 6, wetting the wooden base plate that supports the floor waterproof board 6, and the steel floor panel body below. There was a problem that it caused rust. Further, if the inner sealing material 7 peels off, rainwater or the like directly enters the lower part of the floor waterproof board 6 from there, wetting the base board or rusting the floor panel body.

[Purpose of invention]

The present invention was developed in view of the above-mentioned technical background, and its purpose is to reliably prevent rainwater from entering below the floor waterproof board.

[Disclosure of invention]

In the balcony of the present invention, the upper surface of the beam 1 is covered with waterproof paper 2, a beam cover 3 is placed on the upper surface of the beam 1 through the waterproof paper 2, and a decorative curtain board 4 is installed to cover the outdoor side of the beam 1. The space between the upper end and the beam cover 3 is waterproofed with a sealing material 5, and the space between the end of the floor waterproofing board 6 arranged on the inner circumferential side of the beam 1 and the side surface of the beam 1 is waterproofed with a sealing material 7. It is characterized in that the area above the sealing area is covered with a draining plate 8 while the sealing area is being treated. Even if rainwater or the like infiltrates through the outside sealing material 5, since the waterproof paper 2 is sandwiched between the beam cover 3 and the beam 1, the water is repelled and passes under the beam cover 3. This prevents rainwater from entering inside, and even if the sealing force of the sealing material 7 on the inside is weak, it is covered by the draining plate 8, making it difficult for rainwater to enter. In this way, the path between the decorative curtain board 4 and the beam cover 3 and the path between the beam cover 3 and the floor waterproof board 6 are double waterproofed, so waterproofing can be performed reliably and the base board It will not make the floor panel wet or cause the floor panel itself to rust. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The rear end of a cantilever beam (not shown) that constitutes the structural material of the balcony wing wall 40 is fixed to an auxiliary girder 10 installed horizontally between the upper and lower exterior wall panels 9 of the house. A beam 1 having a U-shaped cross section is suspended between the tips of the support beams to form a framework of the balcony. This beam 1 is made of galvanized steel plate. As shown in FIG. 1, the curtain board base 11 is opposed to the concave side of the beam 1, and the upper end of the curtain board base 11 is overlapped on the upper surface of the beam 1. Furthermore, beam 1
A waterproof paper 2 is laid on top of the beam 1 so as to cover the top of the beam 1 and the top of the curtain base 11. This waterproof paper 2
A beam cover 3 is placed on top of the beam cover 3. The beam cover 3 includes a substantially U-shaped aluminum fixture 12 and a long, inverted groove-shaped beam cover body 13 made of aluminum alloy.
The fixing fitting 12 is fixed to the upper surface of the beam 1 from above the waterproof paper 2 with bolts 14,
The beam cover main body 13 is arranged above the beam 1 so as to cover the fixture 12, and is fixed to the fixture 12 from the side with screws 16. At the same time, a drain plate 8 is provided on the inner peripheral side surface of the beam cover main body 13.
can be installed. Further, the lower end portion of the curtain base 11 is fixed to an eaves siding 17 fixed to the lower surface of the beam 1. The outer edge of the waterproof paper 2 is the curtain board base 1
The stepped portion 18 of the waterproof paper 2 is buried in a caulking material 19 to prevent the end of the waterproof paper 2 from turning over. A decorative curtain board 4 is arranged on the outdoor side of the beam 1 with a curtain board base 11 in between. The upper end of the decorative curtain board 4 is brought into contact with the side surface of the beam cover 3, and a sealing material is placed between the end of the decorative curtain board 4 and the side surface of the beam cover 3. 5 and is waterproofed. The periphery of the floor panel main body 24, which is horizontally arranged within the framework of the balcony, is fixed to the beam 1 and an L-shaped metal fitting 23 attached to the plate 22 of the auxiliary girder 10 with bolts. A plurality of joists 25 are arranged on the upper surface of the joists 24, a plywood base board 26 is placed on the joists 25, and a floor waterproof board 6 made of FRP is placed on the base board 26. has been done. The edge of the floor waterproof board 6 facing the beam 1 is abutted against the side surface of the beam 1 from above the waterproof paper 2, and a sealant 7 is filled between the edge of the floor waterproof board 6 and the waterproof paper 2. It has been waterproofed. The upper part of this sealing part is covered with the above-mentioned draining plate 8. Therefore, the outside of the beam 1 is doubly waterproofed by the sealing material 5 and the waterproof paper 2, and the inside of the beam 1 is doubly waterproofed by the draining plate 8 and the sealing material 7. Further, the edge of the floor waterproofing board 6 facing the house is made to face the outer wall panel 9, a sealing material 27 is filled in between, and the upper part is covered with a draining board 28. In addition, 2
9 is a drainage ditch, and 30 is a handrail.

[Effect of the idea]

As described above, the present invention covers the upper surface of the beam with waterproof paper, places the beam cover on the upper surface of the beam through the waterproof paper, and connects the upper end of the decorative board that covers the outdoor side of the beam with the beam cover. Waterproofing the area between the ends of the floor waterproofing board installed on the inner circumference of the beam with a sealing material, and waterproofing the area between the end of the floor waterproofing board placed on the inner circumference of the beam and the side surface of the beam with a sealing material, and using a draining board above this sealing point. Because it is covered, even if rainwater seeps in through the outside sealant, waterproof paper is sandwiched between the beam cover and the beam, so the water is repelled and passes under the beam cover to the inside. Rainwater does not infiltrate, and even if the sealing power of the inner sealant is weak, it is covered with a draining plate, making it difficult for rainwater to infiltrate. In this way, the path between the decorative curtain board and the beam cover and the path between the beam cover and the floor waterproofing board are double waterproofed, so you can reliably waterproof the baseboard and prevent the floor panel from getting wet. It does not cause the main body to rust.
