[Industrial applications]

 The present invention relates to a storage structure of a joint between a wall of a building and a roof along a roof flow direction, that is, a structure for preventing rain on the wall.

[0002]

[Prior Art]

 FIG. 4 shows an example of a conventional rain-preventing structure of a joint portion (hereinafter, referred to as a “flow wall”) along a flow direction of a roof. In FIG. 4, 1 is a vehicle, 2 is a rafter, and a base plate 3 is stretched on the rafter 2, and an asphalt roofing (waterproof sheet) 4 is laid on the base plate 3. The wall-side end of the asphalt roofing 4 is bent along the vehicle body 1 and is sandwiched between the furring strip 6 fixed to the vehicle body 1 and the outer wall member 8. A receiving bar 7 is arranged near the wall of the asphalt roofing 4, and a long scrap plate 5 made of a metal plate is arranged on the receiving bar 7 along the roof flow direction so as to straddle the scrap plate 5 and the end of the roofing material 9. A headstock 10 is placed on the base plate 3 and these are nailed to the base plate 3. Further, a long rain guard 12 made of a metal plate is laid on the headstock 10 along the roof flow direction.

The waste plate 5 includes a standing plate portion 5A extending to the inside of the outer wall member 8; a horizontal piece 5B extending from the lower end of the standing plate portion 5A in the width direction of the receiving bar 7; 5B is lowered by the thickness of the receiving bar 7 and integrally has a draining plate portion 5C which is sandwiched between the roof material 9 and the asphalt roofing 4. The rain guard 12 includes a standing plate portion 12A extending to the inside of the outer wall member 8; a horizontal piece 12B extending from the lower end of the standing plate portion 12A in the width direction of the headstock 10; and a horizontal piece 12B. The lower side plate 12C, which is lowered by the thickness of the headstock 10, is integrally formed, and a sealing material 14 is injected between the lower side plate 12C and the roof member 9.

Reference numeral 15 is an asphalt felt stretched over the vehicle body 1, and is nailed together with the outer wall material 8 to the furring strip 6 by a nail 17 via the bent portion of the asphalt roofing 4. In the conventional wall-side rain protection structure having the above-described configuration, rainwater and the like flowing down from the outer wall material 8 flow through the lateral pieces 12B of the rain guard 12 to the roof material 9, where drainage is performed downward in the roof flow direction. To be done.

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned conventional structure for protecting rain near the wall, when strong wind rain or a large amount of rainwater that obliquely descends toward the outer wall material 8 flows down from the wall side at the same time, the rain presser 12 has a lower side plate. Rainwater and the like may enter through the gap between the portion 12C and the roof material 9. In preparation for such a case, the sealing material 14 is injected between the lower side plate portion 12C and the roof material 9, but due to aging of the sealing material 14 etc., a gap is created, and from that space to the inside of the roof material 9 Rainwater may enter.

The present invention has been made in view of such circumstances, and an object thereof is to prevent rainwater flowing down from the wall side or rainwater which is blown in an oblique direction of a vehicle body from being used as a roof material. The purpose is to provide a structure for preventing rain from adhering to the walls of the roof, which can be drained downward in the direction of roof flow, while preventing entry into the gap between the roof and the rain plate.

[0007]

[Means for Solving the Problems]

 The structure of the present invention has a structure in which a rain wall on the flow wall is provided with a long rain retainer integrally provided with a standing plate and a draining plate at a joint between the outer wall material and the roof material along the roof flow direction. In the rain protection structure on the side of the flow wall, a cover portion that covers the end portion of the roof material near the wall from above is provided at a middle portion in the width direction of the draining plate portion, and the cover portion and the lower portion of the standing plate portion are provided. It is characterized by the provision of a groove between them to drain rainwater flowing down from the wall side by the roof flow direction downward method.

[0008]

[Action]

 In the structure for rain protection by the wall of the present invention, rainwater and the like that have flowed down from the wall side flow down into the groove portion of the rain retainer and are drained downward in the roof flow direction.

[0009]

【Example】

 Hereinafter, an embodiment of a rain barrier structure on the flow wall of the present invention will be described with reference to FIG. In FIG. 1, reference numeral 21 is a vehicle, 22 is a rafter, and a field board 23 is stretched on the rafter 22, and an asphalt roofing (waterproof sheet) 24 is laid on the field board 23. The end of the asphalt roofing 24 on the wall side is bent along the vehicle body 21, and is sandwiched between the furring strip 26 fixed to the vehicle body 21 and the outer wall member 28.

On the asphalt roofing 24, a roofing material 29 is slightly spaced from the wall, and a roof flow made of a metal plate is provided at a joint portion between the wall and the roof material 29 along the roof flow direction. A long rain guard 25 is fixed in the direction. The rain guard 25 is provided with a standing plate portion 25A that is sandwiched between the sandwiching portion of the asphalt roofing 24 and the outer wall material 28; and extends from the lower end of the standing plate portion 25A in the width direction of the rafter 22. A bottom plate 25B; a cover part 25C projecting from the middle of the bottom plate 25B in the width direction so as to cover the end of the roof material 29; and a draining plate part sandwiched between the roof material 29 and the field plate 23. It has 25D and one. The standing plate portion 25A and the cover portion 25C form a groove portion 30 having the bottom plate 25B as the groove bottom. In addition, a sealing material 31 is injected between the rain cover portion 25C and the roof material 29.

In FIG. 1, reference numeral 32 denotes an asphalt felt stretched over the vehicle body 21, and together with the outer wall material 28, a nail (not shown) is provided on the furring strip 26 via the bent portion of the asphalt roofing 24. It has been stopped. In the structure for preventing rain on the flow wall having the above-described configuration, rainwater and the like that have flowed down from the outer wall material 28 flow down into the groove portion 30 and flow through the groove portion 30 downward in the flow direction of the roof for drainage. The same applies to rainwater of strong wind and rain that obliquely descends on the outer wall material 28. The depth of the groove 30 is determined by the height of the projection of the cover 25C, which is almost the same as the height of the roof material 29 with the clearance at the uppermost point. Therefore, unless the height of the surface of the rainwater, etc., flowing down from the outer wall material 28 is high enough to exceed the thickness of the roof material 29, the rainwater, etc., flowing down from the vehicle is between the cover portion 25C and the roof material 29. There is no way to get into.

In this embodiment, since the groove bottom portion of the groove portion 30 is formed by the entire bottom plate 25B, the receiving bar, the scrap plate, and the coop are omitted. Even if these are omitted, in the structure of the present embodiment, since rainwater or the like flows through the groove portion 30 and is drained downward in the roof flow direction, from the space between the roof material 29 and the rain guard 25 to the inside of the roof material 29. There is no danger of getting in. Furthermore, by omitting these, there is also an effect that it is possible to simplify the troublesome construction which was conventionally performed by laying a receiving bar, a siding board and a head tree in this order on the asphalt roofing at the wall side and nailing them.

Further, in this embodiment, as shown in FIG. 2, the asphalt roofing 35 is not sandwiched between the furring strip 26 and the outer wall material 28, but cut near the end of the roof material 29, 35A and the draining plate portion 25D of the rain retainer may be bonded by the adhesive material 36. As a result, it is possible to prevent the troublesome work of laying the asphalt roofing 35 while bending it at the wall side end, and further to prevent damage to the asphalt roofing. Note that, as shown in FIG. 3, the same effect can be obtained by adhering the asphalt roofing end portion 35A and the draining plate portion 25D via the adhesive tape 37 attached to the base plate 23.

[0014]

[Effect of the device]

 According to the present invention, since the groove provided between the cover and the standing plate drains rainwater and the like that has flowed down from the wall side downward in the roof flow direction, rainwater and the like enter through the gap between the cover and the roof material. There is almost no penetration, and it is possible to improve the waterproofness and durability near the flow wall.
