Masashi rainwater is known (Patent Document 1: JP-A-7-113303). In this rainwater, the main body 1 has a box shape with an upper surface opened, and the upper surface opening serves as a mounting surface 2, and a lid 17 is attached to the opened mounting surface 2. Further, a flange-like flange 6 protruding outward is formed on the peripheral portion of the mounting surface 2 of the main body 1, and a fixture insertion hole 18 is formed in the flange-like flange 6.

  In this case, the fixing tool 5 is inserted into the fixing tool insertion hole 18 from below, and the fixing tool 5 is screwed into the attached surface, whereby the main body 1 is fixedly attached to the attached surface. The lid 17 attached to the mounting surface 2 has a circular hole, and the lower end of the flange is inserted into the circular hole, so that the bottom portion of the body 1 is inserted through the interior of the body 1. The rainwater flows down to the pit 9 formed at the bottom. However, in this conventional rainwater basin, the fixture 5 is screwed in from the lower side of the bowl-shaped flange 6 using a tool such as an electric screwdriver. It was difficult to perform the screwing work. In addition, the flange-shaped flange 6 in which the fixture insertion hole 18 is formed is more prominently protruded toward the outside of the main body 1 and the construction appearance is not good.

  In addition, as shown in FIG. 7, the mounting surface 2 which is the back surface of the box-shaped main body 1 is joined to the mounting surface (outer wall surface) 4 of the building 3, and the fixing surface 5 is a screw. It is also known that rainwater is attached and fixed (Patent Document 2: JP-A-11-210182). In this case, the back plate part 12 of the main body 1 is joined and fixed to the mounting surface 4 with the fixture 5, and a drainage elbow 15 that drains and removes rainwater from the roof of the building 3 is penetrated through the back plate part 12. It is introduced into the main body 1.

Further, a trap 16 is connected to the drop 9 formed at the bottom of the main body 1, and rainwater from the roof is gradually flowed into the main body 1 from the drain elbow 15, and from the drop 9. It is drained to dredge 16. However, in the case of this conventional rainwater, since the fixing tool 5 is screwed from the inner side of the back plate portion 12 of the main body 1, the screw is attached to the upper surface opening of the main body 1 during the screwing operation. It is necessary to remove the lid 17 to be worn, and it is necessary to perform the screwing operation from the inside of the main body 1 using a tool such as an electric screwdriver, which is difficult and difficult to install.

  In the rainwater tank of the present invention, a flange-like flange that protrudes outward is formed on the periphery of the mounting surface of the main body, and screws, nails, etc. are fixed from the fixture insertion surface that is the surface of this flange-like flange. The mounting surface can be joined and fixed to the mounted surface of the building by inserting a tool. When the fixing tool is a screw, it is a screwing operation, and when it is a nail, it is a driving operation. However, the mounting and fixing operation with these fixing tools is easily performed from the outside of the main body. Moreover, since the fixture insertion surface is inclined outward and inclined to the mounting surface side of the building, tools such as an electric screwdriver and a hammer are less likely to hit the outer surface of the main body when mounting and fixing with the fixture. It is easy to perform the mounting and fixing work with the fixing tool. In addition, the hook-shaped flange whose surface is inclined and the fixing tool inserted into the inclined surface (fixing tool insertion surface portion) are not conspicuous from the front side, and the construction appearance is refreshing and good.

  FIGS. 1-3 has shown the rainwater which is one Embodiment corresponding to all Claims 1-3 of this application. In this embodiment, the rainwater basin is attached to the mounting surface 4 of the building 3 with the mounting surface 2 of the box-shaped main body 1 and fixed to the mounting surface 4 with a fixing tool 5 such as a screw or a nail. Is. Then, a flange-like flange 6 projecting outward is formed on the peripheral portion of the mounting surface 2 of the main body 1, and the surface of the flange-like flange 6 is inclined outward toward the mounting surface 4 side of the building 3. This is a fixture insertion surface portion 7 into which the fixture 5 is inserted.

  In the rainwater of this embodiment, the bowl-like flange 6 is formed by bending the peripheral wall of the main body 1 so that the back of the fixture insertion surface portion 7 of the bowl-like flange 6 is hollow. Further, the upper surface and the rear surface of the main body 1 are set as the mounting surfaces 2a and 2b, and the flanges 6a and 6b are formed continuously with the peripheral portions of the mounting surfaces 2a and 2b.

  Hereinafter, the rainwater mass of this embodiment will be described in more detail. FIG. 1 shows a state in which the rainwater trough of this embodiment is constructed on the entrance porch roof 8 of the building 3. In this case, the lower surface of the entrance porch roof 8 becomes the mounting surface 4a of the building 3, and the mounting surface 2a which is the upper surface opening of the main body 1 is joined and fixed to the mounting surface 4a. Here, the fixing tool 5 which is a screw is inserted into the fixing tool insertion surface portion 7a which is an inclined surface of the flange-shaped flange 6a formed in the upper surface opening of the main body 1, and is screwed and fixed to the mounting surface 4a. . A drop port 9 is integrally suspended below the main body 1, and a chain rod 10 for drainage is connected to the drop port 9. Therefore, the rainwater that has accumulated on the entrance porch roof 8 is collected in the main body 1 of the rainwater and then drained down from the pit 9 through the chain rod 10.

  The rainwater trough of this embodiment is manufactured by being integrally molded with a synthetic resin or bent with a metal plate, and as shown in FIGS. It is formed. The main body 1 has a hollow, substantially cubic shape, and is formed by a front plate portion 11, a back plate portion 12, side plate portions 13, and a bottom plate portion 14. The upper surface opening serves as a mounting surface 2a, and the entrance porch roof 8 It is bonded and fixed to the mounted surface 4a which is the lower surface. Further, the outer side surface of the back plate portion 12 which becomes the back surface of the main body 1 also becomes a mounting surface 2b which is bonded and fixed to a mounting surface (outer wall surface) 4b of the building 3 which will be described later. The cylindrical drop port 9 is integrally suspended from the bottom plate portion 14 of the main body 1.

  First, flanges 6a and 6b are formed on the attachment surface 2a which is the upper surface opening of the main body 1 and the attachment surface 2b which is the back surface so as to be continuous with the peripheral portion. In this case, as shown in FIG. 2 (b), the upper edge portions of the front plate portion 11 and the both side plate portions 13 are bent at an upper surface opening of the main body 1 so as to be inclined outward. A flange-shaped flange 6a is formed, and the surface of the flange-shaped flange 6a faces outward and becomes a fixture insertion surface portion 7a inclined toward the mounted surface 4a side of the building 3 (here, the lower surface side of the entrance porch roof 8). . In this way, when the upper edge portion of the peripheral wall (front plate portion 11 and both side plate portions 13) of the main body 1 is bent to form the flange-shaped flange 6a, the back of the fixture insertion surface portion 7a of the flange-shaped flange 6a is formed. The back side is hollow.

Thus, a flange-shaped flange 6b is formed, and the surface of the flange-shaped flange 6b is outward and becomes a fixture insertion surface portion 7b inclined to the attached surface 4b side of the building 3 (herein, the outer wall surface described later). . As described above, when the rear edge portion of the peripheral wall (both side plate portions 13) of the main body 1 is bent to form the flange-shaped flange 6b, the back side behind the fixture insertion surface portion 7b of the flange-shaped flange 6b is hollow. It becomes a shape. In this case, the corner portion formed by the back plate portion 12 and the side plate portion 13 is bent outward in a substantially V shape, and the front side surface thereof becomes the fixture insertion surface portion 7b, which is substantially the same V shape. The inside of the shape is hollow. In FIG. 3A, X indicates the insertion position of the fixture 5.

  Therefore, in the rainwater tank of this embodiment, a flange-like flange 6 projecting outward is formed on the peripheral portion of the mounting surface 2 of the main body 1, and a fixture insertion surface portion that is the surface of this flange-like flange 6. 7, a fixing tool 5 such as a screw or a nail is inserted, and the fixing surface 5 can be joined and fixed to the mounting surface 4 of the building 3 by the fixing tool 5. When the fixing tool 5 is a screw, a screwing operation is performed. When the fixing tool 5 is a nail, a driving operation is performed. However, the fixing and fixing operation using these fixing tools 5 is easily performed from the outside of the main body 1.

  Moreover, since the fixture insertion surface portion 7 is inclined outward and inclined toward the mounting surface 4 side of the building 3, the fixture 5 such as a nail can be inserted from the diagonally outer side to perform the fixing operation. When mounting and fixing with the fixing tool 5, tools such as an electric screwdriver and a hammer are less likely to hit the outer surface of the main body 1, and the fixing and fixing work with the fixing tool 5 is easy to perform. Further, the flange-shaped flange 6 with the inclined surface and the fixing device 5 inserted into the inclined surface (fixing device insertion surface portion 7) are not conspicuous from the front side and the construction appearance is refreshing and good.

  In addition, in the rainwater of this embodiment, the peripheral wall of the main body 1 is bent to form the same flanged flange 6 so that the back side of the fixture insertion surface portion 7 of the flanged flange 6 is hollow. Therefore, the main body 1 and the flange-shaped flange 6 can be easily manufactured as a unit. In addition, in this case, since the back side of the fixing tool insertion surface portion 7 of the flange-shaped flange 6 is hollow, the resistance when the fixing tool 5 is screwed or driven is reduced, and the fixing tool 5 is fixed. It becomes easy to insert into the tool insertion surface portion 7.

  In addition, in the rainwater tank of this embodiment, the upper surface (opening) and the back surface of the main body 1 are used as the mounting surfaces 2a and 2b, and the flanges 6a and 6b are formed continuously with the peripheral portions of the mounting surfaces 2a and 2b. Therefore, as described above, the mounting surface 2a, which is the upper surface of the main body 1, is attached to the mounting surface 4a, which is the lower surface of the entrance porch roof 8 of the building 3, etc. It is possible to cope with both the construction state in which the attachment surface 2b which is the back surface is attached to the attachment surface 4b which is the outer wall surface of the building 3, and the above-described effects are achieved in either case.
