It is installed so that it inclines down toward both ends of the paper.

When connecting the rain gutters 1 so as to be adjacent to each other, a rain gutter connection joint 28 as shown in FIG. 16 is used. The upper joint 29 having an adhesive (hatched portion in the drawing) applied to the entire lower surface is adhered to the inner surface of the connection portion of each rain gutter 1 and the adhesive (hatched portion in the drawing) is applied to the entire upper surface. Connect the lower joint 30 to each gutter 1
By bonding to the lower surface of the connection part, each gutter 1 is connected so as to be continuous. Also, FIG.
5, the end cover 31 is attached.

A draining material 8 is provided between the inner surface of the wall panel 18 and one inner surface of the rain gutter 1 and between the floor base and the other inner surface of the rain gutter 1. Is reliably drained into the rain gutter 1 while being guided by the draining material 8 through the blind cover 32. The lower end of each draining plate 8 is arranged inside the rising piece 9 on both sides of the rain gutter 1, and a gap 10 is provided between the upper part of the rising piece 9 and the lower part of the draining board 8.

The blind cover 32 is a support angle 3 having an L-shaped cross section and installed on the inner surface of the wall panel 18 of the attached structure A.
3 is placed between the support angle 33 and the locking recess 35 such that the ends are respectively placed on the locking recesses 35 formed at the ends of the horizontal plate 34 and the floor plate 22. At an appropriate position in the longitudinal direction of the rain gutter 1, a drainage drain 36 as the water collecting port 5 is attached. A drain gutter 37 connected to a lower part of the drainage drain 36 is a drainage vertical disposed along the outer wall panel 16. It is connected to the upper part of the gutter 38. Drainage drain 36
The upper and lower parts of the call gutter 37 connected to the lower part of FIG.
A rotary elbow 39 as shown in FIG.
The rotary elbow 39 can rotate one end, and can be connected to the other connecting pipe so as to be orthogonal to other connecting pipes as shown in FIG. 5B, and can be changed to a form in which connection can be made almost straight to other connecting pipes as shown in FIG. 5B. The lower part of the drainage drain 36 and the upper part of the call gutter 37 are connected to each other via the upper rotating elbow 39. The upper part of the drainage gutter 38 as the drainage gutter 2 and the rotary elbow 39 provided at the lower part of the call gutter 37 are connected to each other via a vertical joint 40 as shown in FIG. Rainwater flowing into the rain gutter 1 during rainfall is drained from the water collecting port 5 through the drain gutter 2.

The floor plate member 22 mounted and fixed on the upper part of the waterproof sheet 23 is provided with a plurality of outwardly projecting support ridges on the back surface of the thin plate-shaped panel body, and a concave between adjacent support ridges. The main body is formed by forming a groove. The floor plate member 22 is installed on the waterproof sheet 23 so that the groove is orthogonal to the rain gutter 1, and the end of the groove is positioned on the rain gutter 1. The floorboard 22 is made of a non-combustible material such as a cement board, and the floor of the attached structure A can be made to have a nonflammable structure by installing the floorboard 22. A recess is provided in the lower surface of the supporting ridge along the longitudinal direction, and the recess is filled with an adhesive, and the floor plate 22 is bonded and fixed on the waterproof sheet 23 by the adhesive. I have. By using the adhesive in this manner, the floor plate 22 can be bonded and fixed on the floor substrate, and can be bonded and fixed without using screws and nails, and the screws and nails can be fixed to the surface of the floor plate 22. The head of the tool is not exposed and can be finished well.

[0023] Even if rainwater enters the back surface of the floor panel 22, the water flows along a concave groove provided on the lower surface side of the panel body, and the water flowing along the concave groove is a rain gutter. After flowing into the inside 1, it is drained through the rain gutter 1, so that rainwater does not accumulate on the back side of the floor plate 22. At an appropriate position in the longitudinal direction of the rain gutter 1, in addition to the drainage drain 36, an overflow drainage drain 43 as the preliminary water collecting port 4 is attached as shown in FIG. The overflow drainage 43 is provided with a plurality of overflow ports 45 on the upper outer surface of a vertically elongated cylindrical body 44.
From the lower part of 3, a drainage pipe 46 as the secondary drainage gutter 3 is protruded straight downward, and the drainage pipe 46 is an eave ceiling material.
19 is connected to a support member 48 provided. That is, the secondary drainage gutter 3 is open at the eave ceiling 6. A cover 47 as shown in FIG. 9 is attached to a support member 48 to which the lower end of the drainage tube 46 is connected. The cover 47 is provided with a plurality of locking claws 47a. The locking claws 47a are hooked on the openings of the support members 48 to be locked, so that they can be easily attached with one touch from below. In the figure, reference numeral 42 denotes a drain hole.
The provision of the overflow drainage 43 causes a situation in which the drainage drain 36 is clogged for some reason and the drainage is not performed. The drainage is drained from the mouth 45 through the drainage pipe 46 below the eave ceiling material 19 , so that the rainwater overflowing from the rain gutter 1 does not overflow toward the floor of the attached structure A. ing. In addition, in the case of heavy rain, a large amount of rainwater is efficiently drained through the drainage gutter 2 and the water collecting port 5 and the secondary drainage gutter 3 and the preliminary water collecting port 4. Further, if the drainage gutter 2 and the water collecting port 5 and the secondary drainage gutter 3 and the preliminary water collecting port 4 are clogged, or if the drainage cannot be sufficiently drained from each of the downspouts 2 and 3, it is shown in FIG. The rainwater is drained out of the rain gutter 1 through a gap 10 formed between the draining plate 8 and the rising piece 9 of the rain gutter 1 so that the floor of the attached structure A is discharged from the rain gutter 1. It is possible to reliably prevent rainwater from overflowing into the part.

FIGS. 26 to 28 show a case where the attached structure A is a take-out balcony in which the attached structure A protrudes from the space between the first-floor outer wall panel 49 and the second-floor outer wall panel 50 of the building body B toward the outdoor side. In this case, a drainage gutter 38 is provided on the first floor outer wall panel 49 of the building body B.
A long calling gutter 37 extending from a lower portion of the drainage drain 36 is connected to an upper portion of the drainage gutter 38. FIG. 28 shows a floor support 17 used in this embodiment. In this embodiment, the floor support 17 is directly provided from the body difference 51 between the first floor outer wall panel 49 and the second floor outer wall panel 50 of the building body B. The floor support 1 according to the first embodiment is configured to protrude outward by the width of the balcony.
It is longer than 7.
