TECHNICAL FIELD OF THE INVENTION
The present invention relates to a drainage drain installed at a joint portion near a wall such as a portion A or a portion B shown in FIG.
[0002]
[Prior art]
FIG. 2 shows the structure of the connecting portion at the side of the wall of the tiled roof by the cross tile 1, and the construction is usually performed as follows.
First, an asphalt roofing 4 is laid on the field board 3, a part of the asphalt roofing is set up and attached to the wall board 5, and then the tile pier 6 is nailed and fixed. Next, a drainage plate 7 made of a steel plate having a concave groove is attached to a portion where the wall is joined, and one side edge 7a is nailed to the tile bar 6 to be fixed, and a rising portion attached to the wall is provided. The plate 8 is applied to 7b and nailed and fixed. After that, the roof tiles 1 are arranged from the edge of the roof toward the wall, and the roof tiles 1 are laid from the eaves to the ridge, or the roof tiles 11 are stacked on the roof tiles 1 via the mortar 9 while being roofed. After being pressed and fixed by nailing, it is covered with a color steel plate 13, the rising portion is pressed by a plate 14 and fixed to the wall plate 5 by nailing. In the figure, 15 is an outer wall, and 16 is plaster.
[0003]
FIG. 3 shows the structure of the connection part of the tiled roof with the flat roof tiles 18. As shown in FIG. 2, the asphalt roofing 4 is laid on the base plate 3, and the tile pier 6 is nailed and fixed. . Next, after the drainage drain 7 is attached, the tile 18 is laid, a sponge-type sealer 19 is mounted on the tile 18 near the wall, and the cap 12 is mounted on the plate 8 and the sealer 19 and nailed. Thereafter, the color steel plate 13 is put on and fixed by nailing. In the figure, reference numeral 20 denotes a waterproof tape.

[Problems to be solved by the invention]
When roofing is installed near a wall, as shown in FIGS. 2 and 3, the roofing 4 is not bent at a right angle at a corner, and often becomes a state of floating at the corner as shown in FIGS. Tends to. If the drainage drain is mounted in this state, the corner side will be in a floating state. However, if an attempt is made to press down firmly so as not to float, the roofing may be broken at the drained corner.
[0005]
A first object of the present invention is that when roofing is installed at a joint portion near a wall, even if the roofing is in a floating state at a corner portion with the wall, the drainage can be mounted without hindrance. An object of the present invention is to provide a drainage drain that can facilitate construction.
[0006]
A second object of the present invention is to provide a drainage drain particularly suitable for constructing a flat roof tile, in addition to the first object.
[0007]
[Means for solving the problem]
The invention according to claim 1 relates to a drainage drain which achieves the first object, and which is mounted on a roofing laid at a joint part of a wall of a tiled roof and has a concave groove, and in which a drainage corner is provided. Are formed in an arc shape, an inclined shape, or a concave shape.
[0008]
According to the present invention, even if the roofing is in a floating state at the corner portion near the wall, if the corresponding portion of the drainage is arc-shaped, inclined or concave, the arc-shaped or inclined portion at the time of drainage installation. However, even if the roofing is held down, stress concentration does not occur, and the roofing is hardly broken. When the corresponding portion is concave, even if the roofing enters the concave portion, it does not come into contact with the drainage drain, and the roofing does not break at the corresponding portion.
[0009]
In the present invention, the term “concave” refers to, for example, an arc-shaped or square-shaped concave.
[0010]
The invention according to claim 2 relates to draining to achieve the second object, and in the invention according to claim 1, the tiled roof is a tiled roof made of flat tiles, and a portion corresponding to a corner near a drained wall is provided. It is characterized in that it is depressed in a square shape and has a step shape.
ADVANTAGE OF THE INVENTION According to this invention, since a roof tile comes to be supported by the draining step by the wall, the roof support is stabilized and rattling is prevented.
[0011]
The invention according to claim 3 is characterized in that, in the invention according to claim 2, the upper surface of the step supporting the tile by the wall is formed to be inclined downward toward the groove.
ADVANTAGE OF THE INVENTION According to this invention, when water invades a step upper surface, it becomes easy to flow into a groove, and the possibility that water accumulates on a step upper surface is eliminated.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 4 shows the drainage drain 7 attached to the joint portion near the wall shown in FIG. 2 as the drainage drain 21 in which a portion 21a corresponding to a corner beside the wall is formed in an arc shape.
According to the present embodiment, even if the roofing 4 is raised at the corner portion near the wall as shown in the figure, the roofing 4 is not pressed and broken when the drainage cut 21 is attached. Therefore, when installing the roofing 4, it is not necessary to bend the roofing 4 at a corner at a right angle, which facilitates the installation.
[0013]
FIG. 5 shows the drainage drainer 7 attached to the joint shown in FIG. 3 as a drainage drainer 23 in which a portion 23a corresponding to a corner near the wall 21 is depressed into a square shape to be stepped. Can be changed according to the shape of the back surface of the tile 18.
According to the present embodiment, even if the roofing 4 is raised at the corners as shown in the figure, there is no problem in mounting the drainage drain 23, and the roofing 4 can be easily installed. Further, since the roof tiles 18 to be roofed by the walls are supported by the steps 23a, even if the roof tiles are odd as shown in the figure, the supporting state is stable, and no rattling occurs.
[0014]
FIG. 6 is a diagram in which the upper surface 23b of the step 23a shown in FIG. 5 is formed to be inclined downward toward the concave groove 23c of the drainage drain 23, and even if water enters the step upper surface 23b as shown in FIG. It flows in the direction of the arrow without accumulating and flows into the concave groove 23c.
[0015]
【The invention's effect】
According to the invention according to claim 1, even when the roofing is mounted in a state of being lifted up at the corner portion of the wall, it is not pressed and broken at the time of drainage installation, so when installing the roofing, There is no need to bend the roofing at right angles at the corners, which facilitates construction.
[0016]
According to the second aspect of the present invention, even if the flat roof tile that is laid on the wall side is an odd roof tile, the roof tile is supported by the draining step, so that the mounting state is stabilized without rattling.
