Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drainage device that is attached to a drainage hole formed at the bottom of a valley of a folded roof.

Conventionally, the eaves of the valley of a folded roof had only a drainage hole for draining rainwater, and there was a risk that rainwater would fall from the tip of the valley of the folded roof. In some cases, rainwater does not fall into the eaves gutters, and when rainwater falls into the eaves gutters, it tends to scatter from the eaves gutters.

The present invention has been made in view of the above points, and includes a structure in which the upper edge of the drain pipe is inserted into the drainage hole formed at the bottom of the valley of the folded roof, and a line along the inner surface of the bottom of the valley of the folded roof is formed. A flange is formed as shown in FIG. This is a drainage device for a folded roof, which is formed by forming a protrusion on the outer peripheral surface of a cylinder that engages with a drainage hole.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a drainage device for a folded roof.

The drain tool 1 has a flange 4 formed around the upper edge 3 of the drain pipe 2.

The flange portion 4 is formed along the inner surface of the bottom C of the valley B of the folded roof A.

A water stop plate 6 is erected from one side end 5 of the valley B of the folded roof A of the flange portion 4, which is not on the side wall surface DXD side.

Both side edges 7.7 of the water stop plate 6 are formed along the side wall surface DXD of the valley B.

That is, the waterstop plate is formed in an inverted trapezoidal shape and closes the valley B.

Projections 8, 8, . . . are formed on the outer peripheral surface of the drain pipe 2.

The projection 8 is formed along the circumferential direction of the outer peripheral surface of the drain tube 2, and as shown in FIG. 2, the bottom C of the folded roof A is sandwiched between the flange 4 and the projection 8. The drain tool 1 is fixedly locked in the drain hole E.

If the protrusion 8 is inclined obliquely upward as shown in FIG. 3, it will be easier to insert it into the drain hole E, and it will be easier to tightly fix the bottom part C when fixing.

Moreover, by providing a large number of protrusions 8, butts, etc. in the vertical direction, even if the thickness of the folded roof changes due to the insulation material being attached to the back surface, it can be fixed according to the thickness. can.

The drainage device for a folded roof of the present invention has a flange along the inner surface of the bottom of the valley of the folded roof around the upper edge of the drain tube that is inserted into the drainage hole formed at the bottom of the valley of the folded roof. An inverted trapezoidal water stop plate is erected from one end of the flange that is not on the valley side wall surface so that both side edges thereof are along the valley side wall surface, and water is drained on the outer peripheral surface of the drain pipe. It is made by forming a protrusion that locks into the hole, so it can be easily installed in the drainage hole, and it prevents rain and ice from falling from the eave tips of the valleys of folded roofs. Since rainwater does not circulate around, it is smoothly guided to the eaves gutters, and there is less scattering.

In order to ensure close contact and waterproofness between the drainage device and the folded roof, a soft material may be used, for example, a soft material may be provided on both side edges of the water stop plate.

Furthermore, adhesives or caulking materials may be used.

[Brief explanation of the drawing]

Claims (1)

[Scope of utility model registration request] A flange is formed along the inner surface of the bottom of the valley of the folded roof at the periphery of the upper edge of the drain tube that is inserted into the drainage hole formed at the bottom of the valley of the folded roof, and the valley side wall surface of the collar is formed. An inverted trapezoidal water stop plate is erected from one non-side end so that both side edges thereof are along the valley side wall surface, and a protrusion is formed on the outer peripheral surface of the drain pipe to lock into the drain hole.
