Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a water drainage accessory, and more particularly to improvement of a water drainage accessory used in a wall joint portion of a roof surface.

[Conventional technology]

Conventionally, as for roofing construction in a wall joint where the wall of the second floor rises from the roof surface, as shown in FIG. 3, a roofing sheet B is laid on a base plate A, and a receiving bar C is arranged on the wall side to serve as a drainer. The object D is covered with the wall base E and the base plate A, and the roofing material F is placed on the drainage draining accessory D.
, And the roofing material F is pressed down by the headstock G, and the rain-pressing accessory H is put on the roofing material F. One end of the accessory H is applied to the roofing material F and the other end is covered by the wall material I.
It was constructed so that it would be sandwiched between and, and it had rain protection on the wall.

[Problems of conventional technology]

However, since the roofing structure described above is constructed using two components, the drainage drainage component D and the rain-prevention component H, the structure is complicated and the construction is complicated, and the receiving bar C is used.
The use of woody materials such as Kasaki and Kasaki G increases, and corrosion of these woody materials due to rainwater becomes a problem.

Therefore, assuming that the drainage drainage component and the rain-prevention component are integrated, as shown in FIG.
A draining accessory L having a character shape and having a bent portion K formed on the vertical piece J is manufactured, and the accessory L is applied to a corner portion between the wall foundation E and the field board A, and the roof material F Is the bent portion K
A construction method of fitting the groove N formed between the side piece M and the lateral piece M is considered.

However, in this structure, since the vertical piece J and the horizontal piece M of the draining accessory L are in close contact with the wall base E and the base plate A, respectively, and the above-mentioned receiving rails are not used, the roof There is a tendency that rainwater that flows into the groove N from above the material F flows from between the horizontal piece M and the base plate A to between the vertical piece J and the wall base E and lacks waterproofness.

[Problems to be solved by the device]

In view of the above problems, the present invention has been made with the object of providing a draining accessory that simplifies the roofing structure near the wall and is easy to construct, and that ensures rain protection on the wall. is there.

[Technology that has solved the problem]

That is, the water draining accessory of the present invention has a vertical piece portion and a horizontal piece portion integrally connected from the lower end of the vertical piece portion in the cross-sectional shape, and the water return portion is provided at the tip of each of these piece portions. While being folded back, a bending portion is projected at a substantially intermediate height portion of the vertical piece portion in a direction substantially parallel to the horizontal piece portion, and a roof material fitting groove is formed between the bending portion and the horizontal piece portion. , And the vertical piece portion connecting the bent portion and the horizontal piece portion to the tip side of the horizontal piece portion higher than the vertical piece portion above the bent portion, at a position not more than half of the protruding amount of the bent portion, It is characterized in that it is provided in a staggered manner.

〔Example〕

 Next, an embodiment of this invention will be described.

FIG. 1 is a sectional view of an embodiment of the present invention, and FIG. 2 is a usage state diagram of the embodiment.

The draining accessory 1 of the present invention is made of sheet metal, and has a vertical piece portion 2 and a horizontal piece portion 3 (discarded plate portion) integrally connected from the lower end of the vertical piece portion 2 in a sectional shape. , These pieces 2,
The water repellent portions 4 and 5 are respectively folded back at the tip of 3, and the bent portion 6 is projected at a substantially intermediate height portion of the vertical piece portion 2 in a direction substantially parallel to the lateral piece portion 3 to bend the bent piece 6. A roof material fitting groove 8 is formed between the portion 6 and the horizontal piece portion 3, and the bent portion 6 is formed.
The vertical strip portion 2a connecting the horizontal strip portion 3 and the horizontal strip portion 3 is located at the tip end side of the horizontal strip portion 3 above the vertical strip portion 2b above the bending portion 6 and is half the protruding amount of the bending portion 6 as shown in the figure. It is provided at the following positions with a staggered position.

[Action]

If the water draining accessory 1 having the above structure is used, the accessory 1 is attached to the corner portions of the wall base 9 and the base plate 10 in close contact with each other, and the roof material 7 is fitted to the roof material fitting portion 8. By roofing in this way, the roofing material 7 can be pressed without using two accessories as in the prior art, and the use of wood material such as a receiving rail can be wiped off. In addition, even if rainwater that has flowed into the roof material fitting groove 8 from the top surface of the roof material 7 enters between the lateral piece 3 of the draining accessory 1 and the base plate 10, it will adhere to the wall base material 9 closely. In the vertical strip portion 2, the portion 2a continuous with the horizontal strip portion 3 is separated from the wall substrate 9, so that rainwater can be prevented from staying due to the capillary phenomenon and the wall substrate 9 can be kept wet. Is prevented. Further, since the permeated water also evaporates and escapes through this space, the dry state of the wall base 9 and the field board 10 is maintained.

In addition, 10 is a roofing sheet.

〔effect〕

As described above, in the roofing construction of the wall mating portion of the roof surface using the draining accessory of the present invention, since the construction is a work using a single draining accessory, the structure is simple, The number of parts is small and the construction can be performed easily, and the use of wood material is reduced, so that the occurrence of corrosion can be suppressed. In addition, since it is possible to prevent rainwater from entering the wall base, it is highly waterproof, and even if rainwater may infiltrate, it can be dried in an early stage to keep the wall base or baseboard moist for a long time. There are various practical effects such as no effect.
