Japanese Unexamined Patent Publication No. 2016-79625

The draining member described in Patent Document 1 is formed by bending a single metal flat plate, and the bottom plate portion is once inclined diagonally upward from a portion corresponding to the lower end of the front hanging plate portion of the metal flat plate. It is configured to be folded. Therefore, the bottom plate portion is formed in a flat plate shape, and the strength is relatively low. Therefore, when the rear end of the bottom plate portion of the draining member is attached to a building structure such as a foundation, the rear end of the bottom plate portion may hang down, and the height position of the rear end tends to vary. As a result, it takes time and effort to adjust the attachment of the rear end of the bottom plate portion of the draining member, and there arises a problem that work efficiency is lowered.

In addition, a plurality of types of draining members of this type are manufactured having different horizontal distances, so-called protrusion widths, between the mounting plate portion and the front hanging plate portion. Since the height of the mounting plate portion, the inclination angle of the rainwater guide portion, and the height of the front hanging portion are the same in such a plurality of types of draining members, if the length of the protruding width is different, the mounting plate The height (mounting width) of the upper end of the portion and the rear end of the bottom plate portion is different. That is, the longer the protrusion width, the longer the mounting width. In addition, in the installation work of such a drainer member, it is a general method to attach the draining member along the upper end of the mounting plate portion along the ruled line (inking line) which is a horizontal line drawn on the mounting surface of the base or the like. It is said that. Since the scribe is drawn with reference to the rear end of the bottom plate of the drainer member, if the mounting width is different for each type of drainer member as described above, the height of the scriber to be drawn will also be different for each type of drainer member. Will be. As a result, in the case of the draining member having a different mounting width for each type, it is necessary to make the height position for drawing the ruled line different according to the protruding width of the draining member to be used, which makes the work cumbersome.

Therefore, an object of the present invention is to provide a draining member and a method for manufacturing the draining member, which can facilitate the attachment work of the draining member.

The draining member of the present invention is formed by bending a single metal plate, and has a vertically planar mounting plate portion, a rainwater guide plate portion extending forward from the lower end of the mounting plate portion, and the rainwater guide. Attached to the lower end of the outer wall of the base of the building or the overhang, which includes a front hanging plate portion extending downward from the front end of the plate portion and a bottom plate portion extending rearward from the lower end of the front hanging plate portion. In the draining member used, the front end of the bottom plate portion is bent upward from the lower end of the front hanging plate portion, and the rear end is located above the lower end of the front hanging plate portion, and the front end and the rear of the bottom plate portion are located. The bent portion having at least 3 or more bent portions in the middle between the ends and at least 3 or more, the bent portion located at the lowermost position is located below the lower end of the front hanging plate portion. ..

According to this, since the bottom plate portion has at least three bent portions, the strength of the bottom plate portion is improved, and it is possible to stabilize the height position of the rear end of the bottom plate portion in the vertical direction. Therefore, the work of attaching the draining member becomes easy. Further, the bottom plate portion has at least three bent portions, and when forming the bent portions, the height position of the rear end of the bottom plate portion can be set to a predetermined position. That is, even if the draining members have different protrusion width sizes, the mounting width (height from the upper end of the mounting plate portion to the rear end of the bottom plate portion) of the draining member is set to be the same. Even if the size is different, it is possible to attach the drainer member with the same marking position. In addition, it is possible to add a millipede return function that prevents the millipede that has climbed up from the ground surface to the outer surface of the foundation and crawls up from the draining member to invade the outer wall or the underfloor. In particular, when the ventilation hole is provided in the bottom plate portion on the front side of the bent portion arranged at the lowermost position, it is possible to prevent the millipede from invading from the ventilation hole. Further, it is more preferable that the bottom plate portion has a folded portion folded in the vertical direction in the bent portion arranged at the lowermost position, and by doing so, the lower end of the folded portion is formed on the front hanging plate portion. It protrudes downward from the lower end, which is more effective as a millipede return. Even if rainwater is blown up by the wind along the wall surface of the building behind the bottom plate, for example, the outer surface of the foundation or the underside of the eaves, the bottom plate protrudes below the lower end of the front hanging plate due to the bent portion. Rainwater can be guided downward at the portion, and it is possible to reduce the amount of rainwater being blown back or blown forward from the front hanging plate portion. Further, for example, when a ventilation hole is provided at a position above the lower end of the front hanging plate portion and in front of the bent portion arranged at the lowermost position, the bent portion is located below the ventilation portion. Therefore, when the drainer member is attached to the foundation on the foundation, even if rainwater is blown up along the outer surface of the building such as the foundation by the wind, rainwater will flow from the ventilation part to the inside of the drainer member. It can be prevented from invading.
In the present invention, it is preferable that the bottom plate portion has a folded portion that is folded up and down by the bent portion and folded. As a result, the height position of the rear end of the bottom plate portion becomes more stable.

Further, in the present invention, it is preferable to further include a bent plate portion that is bent upward from the rear end of the bottom plate portion and extends. As a result, it is possible to reduce the possibility of injury caused by the operator's hand touching the rear end of the bottom plate portion during handling. Further, when the ventilation hole is provided in the bottom plate portion, even if rainwater is blown from the ventilation hole, it is possible to suppress the blown rainwater from entering the inside of the building.

Further, in the present invention, the bottom plate portion has a portion arranged above the lower end of the front hanging plate portion between the front end of the bottom plate portion and the bent portion located at the lowermost position. It is preferable that the portion is provided with a ventilation portion composed of a plurality of ventilation holes penetrating in the thickness direction. As a result, the ventilation portion is provided at a position above the lower end of the front hanging plate portion, so that the intrusion of rainwater can be reduced and the ventilation holes are less noticeable.

Further, in the present invention, it is preferable that the portion is inclined upward as it goes backward. As a result, the infiltration of rainwater can be further reduced, and the ventilation holes become less noticeable.

Further, in the method for manufacturing a draining member of the present invention, a vertical plane mounting plate portion, a rainwater guide plate portion extending forward from the lower end of the mounting plate portion, and a rainwater guide plate portion extending downward from the front end of the rainwater guide plate portion. A single drainer member attached to the lower end of the outer wall of the base of the building or the overhang, which has a front hanging plate portion to be pulled out and a bottom plate portion extending rearward from the lower end of the front hanging plate portion. In the method of manufacturing a draining member manufactured by bending a metal plate of the above, the draining member is bent upward from the lower end of the front hanging plate portion, and at least three or more bent portions are formed behind the lower end of the front hanging plate portion. It is provided with a bottom plate portion forming step for forming the bottom plate portion. Then, in the bottom plate portion forming step, the bent portion located at the lowermost position among the at least three or more bent portions is formed at a position lower than the lower end of the front hanging plate portion.

According to this, it becomes possible to manufacture a bottom plate portion having at least three bent portions. Therefore, the strength of the bottom plate portion is improved, and it is possible to stabilize the height position of the rear end of the bottom plate portion in the vertical direction. Therefore, the work of attaching the draining member becomes easy. Further, when forming at least three or more bent portions on the bottom plate portion, the height position of the rear end of the bottom plate portion can be set to a predetermined position. That is, even if the draining members have different protrusion width sizes, the mounting width (height from the upper end of the mounting plate portion to the rear end of the bottom plate portion) of the draining member is set to be the same. Even if the size is different, it is possible to attach the drainer member with the same marking position.

According to the draining member of the present invention, since the bottom plate portion has at least three bent portions, the strength of the bottom plate portion can be improved and the height position of the rear end of the bottom plate portion can be stabilized in the vertical direction. It will be possible. Therefore, the work of attaching the draining member becomes easy. Further, the bottom plate portion has at least three bent portions, and when forming the bent portions, the height position of the rear end of the bottom plate portion can be set to a predetermined position.

Further, as shown in FIGS. 4 and 5, the extension plate portion 55a is provided with a ventilation portion 17 composed of a plurality of ventilation holes 17a penetrating in the thickness direction. Further, as shown in FIG. 4, the ventilation hole 17a is formed so as to extend from the extension plate portion 55a to the upper end portion of the extension plate portion 55b via the bent portion 16a.

As shown in FIG. 6, the height of the draining member 50 from the upper end of the mounting plate portion 11 to the rear end of the bottom plate portion 54 (that is, the mounting width of the draining member 50) is the height of the draining member 1 in the vertical direction C. It is configured to be the same as the height (mounting width of the draining member 1) from the upper end of the mounting plate portion 11 to the rear end of the bottom plate portion 14. More specifically, the positions of the three bent portions 16a to 16c in the vertical direction C are adjusted, and the bottom plate portion 54 is moved in the vertical direction C so that the length of the extension plate portion 55b is slightly longer than that of the extension plate portion 15b. By bending to, even if the protruding width of the draining member 50 and the protruding width of the draining member 1 are different, the mounting width of the draining member 50 and the mounting width of the draining member 1 can be set to be the same. ..

When the bottom plate portions 14 and 54 have three bent portions 16a to 16c in this way, the height position of the rear end of the bottom plate portions 14 and 54 is set to a predetermined position when forming these bent portions 16a to 16c. It becomes possible to. That is, even if the drainer members 1,50 have different protrusion width sizes, by making the mounting widths of the drainer members 1,50 the same, the marking position is the same even if the drainer size is different. It becomes possible to attach the drainer members 1, 50.

The method for manufacturing the above-mentioned draining members 1, 50 will be described below. Since the draining members 1 and 50 have the same manufacturing method, the manufacturing method of the draining member 1 will be described.

In order to manufacture the draining member 1 in the present embodiment, first, a long 0.35 mm steel plate wound in a roll shape is cut to a predetermined length (cutting step). Next, a plurality of ventilation holes 17a are formed in the cut steel plate using a lathe (ventilation hole forming step). Next, the steel plate is bent using a molding machine to form the mounting plate portion 11, the guide plate portion 12, the front hanging plate portion 13, the bottom plate portion 14, and the bent plate portion 15e of the draining member 1 (bending step).

In the bending step when forming the bottom plate portion 14, three bent portions 16a to 16c are formed in the bottom plate portion 14 by bending the steel plate (bending portion forming step). At this time, in the vertical direction C, the steel plate is bent so that the height from the upper end of the mounting plate portion 11 to the rear end of the bottom plate portion 14 (that is, the mounting width) becomes a predetermined width, and the three bent portions 16a to 16c To form. As a result, when forming the three bent portions 16a to 16c on the bottom plate portions 14, 54, the height position of the rear end of the bottom plate portions 14, 54 can be set to a predetermined position. That is, even if the drainer members 1 have different protrusion width sizes, the mounting widths of the drainer members 1 and 50 are set to be the same, so that the marking positions are the same even if the drainer width sizes are different. It is possible to attach the drainer members 1, 50.

As described above, according to the drainer members 1,50 of the present embodiment, the bottom plate portions 14, 54 have three bent portions 16a to 16c, so that the strength of the bottom plate portions 14, 54 is improved. It is possible to stabilize the height position of the rear ends of the bottom plate portions 14, 54 in the vertical direction C. Therefore, when the draining members 1, 50 are attached, the rear ends of the bottom plate portions 14, 54 are less likely to swing up and down. Therefore, the rear ends of the bottom plate portions 14, 54 can be easily brought into contact with the decorative mortar 104, and the mounting work becomes easy.

Further, ventilation portions 17 are provided on the extension plate portions 15a and 55a of the bottom plate portions 14 and 54. Since the ventilation portion 17 is provided at a position above the lower end of the front hanging plate portion 13, the intrusion of rainwater can be reduced and the ventilation hole 17a becomes inconspicuous.

Further, the extension plate portions 15a and 55a are inclined upward as they go backward. As a result, the infiltration of rainwater can be further reduced, and the ventilation holes 17a become less noticeable.

Further, the bottom plate portions 14 and 54 have folded portions 15b and 15c folded back in the vertical direction C by the bent portions 16a and 16b. As a result, the bottom plate portions 14, 54 are less likely to swing in the vertical direction C. Therefore, the height position of the rear ends of the bottom plate portions 14, 54 is more stable.

Further, the extension plate portions 15a and 55a are arranged in front of the folded-back portions 15b and 15c. As a result, the infiltration of rainwater can be further reduced.

Further, a bent plate portion 15e is formed at the rear ends of the bottom plate portions 14, 54. As a result, even if rainwater is blown from the ventilation hole 17a, it becomes difficult for the blown rainwater to exceed the folded plate portion 15e. Therefore, it is possible to prevent rainwater from entering the inside of the building.

Further, among the three bent portions 16a to 16c, the bent portion 16b arranged at the lowermost position is arranged below the lower end of the front hanging plate portion 13. As a result, the lower ends (folded portions 16b) of the folded portions (folded portions) 15b and 15c protrude below the lower ends of the front hanging plate portion 13, so that the outer surface of the foundation is climbed up from the ground surface. It is possible to prevent the millipede from invading the outer wall or the underfloor by raising the draining members 1, 50. Further, since the bent portion 16b is located below the ventilation portion 17 provided above the lower end of the front hanging plate portion 13, rainwater can be discharged from the decorative mortar 104 (outer surface of the foundation) behind the bottom plate portion 14. Even if it is rolled up by the wind, the folded-back portion 15c can reduce the amount of rainwater blown forward, and as a result, it is possible to prevent the rainwater from entering the inside of the draining members 1, 50 from the ventilation portion 17.

As shown in FIG. 7, the bottom plate portion 64 of the draining member 60 extends vertically upward from the lower end of the front hanging plate portion 13 instead of the extension plate portions 15a and 55a of the draining members 1,50 in the above-described embodiment. It may have an extension plate portion 65a1 to be extended and an extension plate portion 65a2 extending diagonally upward and backward from the upper end of the extension plate portion 65a1. The extension plate portion 65a2 of the draining member 60 in this modification is also arranged at a position above the lower end of the front hanging plate portion 13, and the ventilation portion 17 is formed in the extension plate portion 65a2. Further, as shown in FIG. 7, the plurality of ventilation holes 17a constituting the ventilation portion 17 are formed extending from the extension plate portion 65a2 to the upper end portion of the extension plate portion 15b via the bending portion 16a. ing. Even in such a draining member 60, the same effect can be obtained in the same configuration as the above-mentioned draining members 1, 50. Further, since the draining member 60 has four (3 or more) bent portions 16a to 16c, 66e, the same effect as the above-mentioned draining members 1, 50 can be obtained.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made as long as they are described in the claims. For example, the draining members 1, 50, 60 in the above-described embodiment have three or four bent portions 16a to 16c, 66e, but may have five or more bent portions. Further, the extension plate portions 15b and 55b in the above-described embodiment extend downward in the vertical direction from the rear ends of the extension plate portions 15a and 55a, but extend in the vertical direction from the rear ends of the extension plate portions 15a and 55a. It may extend upward. In this case, the extension plate portion 15c may extend downward in the vertical direction from the upper ends of the extension plate portions 15b and 55b. Also in this case, the same effect as the above-mentioned draining members 1, 50 can be obtained.

Further, the draining members 1, 50, 60 do not have to have the ventilation unit 17. Further, the ventilation portion 17 may be provided on the extension plate portions 15d and 55d. Further, the extension plate portions 15a, 55a, 65a2 may not be inclined upward as they go backward, may be horizontal, or may be inclined downward as they go backward. Further, the bottom plate portions 14, 54, 64 may be composed of only a plurality of extending plate portions extending in a direction intersecting the vertical direction C. Further, the draining members 1, 50, 60 may not have the bent plate portion 15e, or may be a folded portion as if folded instead of the bent plate portion 15e.

The above-mentioned draining members 1, 50, 60 are shown as examples of those attached to the base 103 and used, but of course, they are attached to an overhang portion protruding from the outer wall of a building such as a roof, a veranda, and a balcony. It is also possible.

FIG. 8 shows an example of a draining member used for the overhang portion. In this draining member 70, instead of the extension plate portions 15d and 55d of the draining members 1, 50 described above, the extension plate portion 75d of the corresponding portion extends rearward from the mounting plate portion 11. It is formed. Further, instead of the above-mentioned bent plate portion 15e of the draining member 1,50, the corresponding bent plate portion 75e is extended by the bent portion 16d of the rear end (rear end of the extension plate portion 75d) of the bottom plate portion 74.
