  The middle plate-like portion 12 is divided into five equal parts in the longitudinal direction by four cut portions 14a, 14b, 14c and 14d. In other words, the middle plate-like portion 12 is divided into five middle plate-like portions 121, 122, 123, 124, and 125 in parallel in the longitudinal direction.

(Lower plate 13)
The lower plate-like portion 13 is formed into a flat plate shape by being bent along a fold line 30 which is the lower end of the middle plate-like portion 12. The lower plate-like portion 13 is bent vertically downward from the lower end of the middle plate-like portion 12. Thereby, the lower plate-like portion 13 can prevent rainwater or the like guided by the middle plate-like portion 12 from flowing in the direction of the base packing 3 for forming the ventilation gap. Therefore, it is preferable that the lower end of the lower plate-like portion 13 is a position below the lower end of the base packing 3.

The lower plate-like portion 13 is divided into five equal parts in the longitudinal direction by four cut portions 14a, 14b, 14c and 14d. That is, the lower plate-like portion 13 is divided into five lower plate-like portions 131, 132, 133, 134, and 135 in the longitudinal direction.
Further, the lower plate-like portion 13 is formed with a folded piece 15 by folding back from the folding line 40 which is the lower end of the lower plate-like portion 13, and the cut edge of the folded piece 15 facing the cut portions 14 a, 14 b, 14 c, and 14 d is formed. On one side, notches 15a are provided. In this way, by folding back the lower end of the lower plate-like portion 13, it is possible to prevent the hand and fingers from being injured after installation and installation when the drainer 1 is handled.

(Incisions 14a, 14b, 14c, 14d)
The cut portions 14 a, 14 b, 14 c, and 14 d are cut portions that are cut linearly from the lower end of the lower plate-like portion 13 to the upper end of the middle plate-like portion 12. That is, the upper ends of the middle plate-like portions 121, 122, 123, 124, and 125 divided into five are connected to the lower end of one upper plate-like portion 11. The upper ends of the lower plate-like portions 131, 132, 133, 134, and 135 are connected to the lower ends of the middle plate-like portions 121, 122, 123, 124, and 125, respectively.

(Grooves 151, 152, 153, 154, 155)
Grooves 151 to 155 are formed by folded pieces 15 at the lower end of the lower plate-like portion 13.

  Each groove part 151-155 is formed in the width | variety more than the thickness of the lower side plate-shaped part 13. As shown in FIG. Further, the folded pieces 15... Of each of the groove portions 151 to 155 are formed shorter than the respective lower plate-like portions 13 in the longitudinal direction by cutting away the left end portion and forming a notch portion 15a. Accordingly, the lower plate-like portion 13 on the side where the end portions of the respective folded pieces 15... Of the groove portions 151 to 155 are cut off is adjacent to the lower portion divided by any one of the cut portions 14a, 14b, 14c, and 14d. It can be inserted into the grooves 151 to 155 folded back from the side plate-like portion 13. Moreover, since the adjacent groove parts 151-155 contact | abut when the lower side plate-shaped part 13 is inserted in the groove parts 151-155, the distance of insertion is restrict | limited. Thereby, when installing the draining part 1 for bending parts, it can avoid that the lower side plate-shaped part 13 moves excessively in an insertion direction. Further, if the cut width of the cutout portion 15a at the left end of the folded piece 15 is increased, the allowable dimension of the overlapping width of the middle plate-like portion 12 and the lower plate-like portion 13 in the cut portions 14a, 14b, 14c, and 14d. The drainer 1 can be curved into larger and various shapes. In addition, the notch 15a does not need to be formed in the folded piece 15 connected to the lower plate-like portion 13 (lower plate-like portion 131) that is not inserted into any of them.

(Auxiliary notches 16a, 16b, 16c, 16d)
Moreover, the auxiliary | assistant notch part 16 which follows each of notch part 14a * 14b * 14c * 14d is formed in the lower end of the upper side plate-shaped part 11. FIG. As a result, the upper plate-like portion 11 can be bent more easily, and even when the upper plate-like portion 11 is bent and a force is generated in which the middle plate-like portions 12 repel each other in the horizontal direction. It is possible to prevent the upper plate-like portion 11 from cracking from the notches 14a, 14b, 14c, and 14d by force.

(Assembling method)
Specifically, with reference to FIG. 5, a method for assembling the bending portion drainer 1 will be described with respect to a portion divided by the cut portion 14 d. The other cut portions 14a, 14b, and 14c are the same and will not be described.

  First, the upper plate-like portion 11 is bent in accordance with the concave curved portion to be installed. At that time, the middle plate-like portion 125 is overlapped below the middle plate-like portion 124. Further, the lower plate-like portion 135 is superimposed on the rear surface side of the lower plate-like portion 134. At this time, the folded piece 15 at the lower left end of the lower plate-shaped portion 135 is cut out, so that it is shorter in the vertical direction than other portions. Therefore, when the middle plate-like portion 125 is overlapped below the middle plate-like portion 124, the lower left end portion of the lower plate-like portion 135 is located above the groove bottom surface of the groove portion 154. Therefore, the lower left end portion of the lower plate-like portion 135 can be guided into the groove portion 154 in the inserted state.

  Thus, when the upper plate-like portion 11 is curved, the middle plate-like portion 125 is superimposed below the middle plate-like portion 124, and the middle plate-like portion 124 is piled below the middle plate-like portion 123. The middle plate-like portion 123 is superimposed below the middle plate-like portion 122, and the middle plate-like portion 122 is superimposed below the middle plate-like portion 121. In addition, the lower plate-shaped portion 135 is superimposed on the rear side of the lower plate-shaped portion 134 and the lower left end portion thereof is inserted into the groove portion 154, and the lower plate-shaped portion 134 is superimposed on the rear side of the lower plate-shaped portion 133 and The lower left end portion is inserted into the groove portion 153, the lower plate-like portion 133 is overlapped behind the lower plate-like portion 132, the lower left end portion is inserted into the groove portion 152, and the lower plate-like portion 132 is inserted into the lower plate-like portion 131. And the lower left end thereof is inserted into the groove 151.

  As a result, as shown in FIG. 2, the bending portion drainer 1 can be assembled and installed on the base 2 formed on the concave curved portion. In addition, although not shown in figure, the caulking process which fills the clearance gap which arises by notch part 14a * 14b * 14c * 14d with a joint material etc. may be performed before or after installation.

  In this way, the middle plate-like portion 12 divided into two or more by the cut portions 14a, 14b, 14c, and 14d is continuous with the upper plate-like portion 11, and further from each middle plate-like portion 12 to the lower plate-like portion. 13 is continuous. When the rear surface of the upper plate-like portion 11 is set along the concave curved portion, the upper plate-like portion 11 is bent according to the concave curved portion. When the upper plate-like portion 11 is curved, the middle plate-like portions 12 and the lower plate-like portions 13 divided by the cut portions 14a, 14b, 14c, and 14d are overlapped and assembled. As a result, the upper plate-like portion 11 is installed along the concave curved portion, and the gaps by the cut portions 14a, 14b, 14c, and 14d are closed, so that the upper plate-like portion 11 is installed in the concave curved portion of the building. In addition, rainwater or the like flowing down through the building can be introduced and dropped outside without entering the inside of the middle plate-like portion 12 and the lower plate-like portion 13. Moreover, since it is the structure which can fold and assemble the one steel plate 10, cost reduction can be aimed at.

  Further, when the upper plate-like portion 11 is bent according to the concave curved portion, and the middle plate-like portion 12 and a part of the lower plate-like portion 13 are stacked and assembled in the cut portions 14a, 14b, 14c, and 14d, The lower ends of the other lower plate-like portions 13 divided by the cut portions 14a, 14b, 14c, and 14d can be inserted into the grooves 151 to 155 at the lower ends of the side plate-like portions 13. Thereby, the movement of the inserted lower plate-like portion 13 in the downward direction and the front-rear direction is restricted by the grooves 151 to 155. Further, the inserted lower plate-like portion 13 is restricted from moving upward by the middle plate-like portion 12 continuing from the inserted lower plate-like portion 13. Further, the movement of the lower plate-like portion 13 in the left-right direction is restricted by the upper plate-like portion 11 being bent according to the concave curved portion. As a result, the lower plate-like portion 13 divided by the cut portions 14a, 14b, 14c, and 14d, and the middle plate-like portion 12 continuing to the lower plate-like portion 13 can be easily fixed.

(Lower plate-like portion 213)
The lower plate-like portion 213 is formed in a flat plate shape by being bent along a fold line 230 that is the lower end of the middle plate-like portion 212. The lower plate-like portion 213 is bent vertically downward from the lower end of the middle plate-like portion 212. Thereby, the lower plate-like portion 213 can prevent rainwater or the like guided by the middle plate-like portion 212 from flowing in the direction of the base packing 3 (see FIG. 1) for forming a ventilation gap. . Therefore, it is preferable that the lower end of the lower plate-shaped portion 213 is positioned below the lower end of the base packing 3.

  A lower folded piece 215 is formed on the lower plate-shaped portion 213 by folding back from the folding line 240 that is the lower end thereof. In this way, by folding back the lower end of the lower plate-like portion 213, it is possible to prevent injury to the hand and fingers after installation and installation during handling of the bending portion drainer 201. Further, the lower folded piece 215 of the lower plate-like portion 213 is provided with triangular lower notches 215a, 215b, 215c, and 215d on the line segments in the cut direction of the upper notches 214a, 214b, 214c, and 214d. It has been. Thereby, it is possible to prevent wrinkles from being formed on the lower folded piece 215 when the draining drain 201 for the bending portion is bent at the time of assembly or the like.

(Upper notches 214a, 214b, 214c, 214d)
The upper cut portions 214a, 214b, 214c, and 214d are cut portions that are linearly cut from the upper end of the upper plate portion 211 to the lower end of the middle plate portion 212. That is, the lower ends of the middle plate-like portions 2121, 2122, 2123, 2124 and 2125 divided into five are connected to the upper end of one lower plate-like portion 213. The lower ends of the upper plate-like portions 2111, 2112, 2113, 2114, and 2115 are connected to the upper ends of the middle plate-like portions 2121, 2122, 2123, 2124, and 2125, respectively.

(Grooves 2171, 2172, 2173, 2174, 2175)
Grooves 2171 to 2175 (see FIG. 7) are formed by upper folded pieces 217...

  Each groove part 2171-2175 is formed in the width | variety more than the thickness of the upper side plate-shaped part 211. FIG. Further, the folded pieces 217... Forming the groove portions 2171 to 2175 are longer than the upper plate-like portions 211 by cutting the right end portion to form the upper cutout portions 217a, 217b, 217c, and 217d. It is short in the direction. As a result, the upper plate-like portion 211 on the side where the ends of the folded pieces 217... Of the grooves 2171, 2172, 2173, 2174, 2175 are cut off is any one of the upper cut portions 214 a, 214 b, 214 c, 214 d Can be inserted into the grooves 2171, 2172, 2173, 2174, and 2175 that are folded back from the adjacent upper plate-like portions 211. Further, when the upper plate-like portion 211 is inserted into the groove portions 2171, 2172, 2173, 2174, and 2175, the adjacent groove portions 2171, 2172, 2173, 2174, and 2175 are in contact with each other, so that the insertion distance is limited. The Thereby, when the draining part 201 for bending parts is installed, it can avoid that the upper side plate-shaped part 211 moves excessively in an insertion direction. If the cut width of the notch 217a at the left end of the upper folded piece 217 is increased, the overlapping width of the middle plate portion 212 and the upper plate portion 211 in the upper cut portions 214a, 214b, 214c, and 214d is increased. Allowable dimensions can be increased and the drainer 201 can be curved into larger and various shapes. Note that the upper notch portion 217d may not be formed in the upper folded piece 217 connected to the upper plate-like portion 211 (upper plate-like portion 2115) that is not inserted into any of them. A plurality of drainers 201 may be used by connecting them horizontally. Further, as shown in FIGS. 6 to 8, a connecting member for connection may be provided at one end of the middle plate-like portion 212 and the lower plate-like portion 213. Moreover, when using it by connecting, you may provide the joiner which covers a connection part.
