Description

  The present invention relates to a gutter installed such that a gutter plate projects forward from the outer wall surface of a building.

  Conventionally, as such a cage, there is a structure in which the rear end portion of the roof plate is held over the entire width on a holding frame attached to the outer wall surface of the building. In addition to the one plate structure as a whole, there is a plate formed by connecting a plurality of plate members in the width direction (see, for example, Patent Document 1).

Japanese Patent No. 3854626

  As shown in FIG. 9, the saddle plate is composed of a plurality of plate members 20, 21, and 22 that are connected in the width direction so that the side end surfaces abut each other. Each plate member 20, 21 and 22 is a hollow body formed by extrusion molding of aluminum. Each plate member 20 at an intermediate position has both end faces, and each plate member 21, 22 at both positions has an inner end face, respectively. It has a structure that can be engaged with and disengaged. The rear end of the slab 2 is held over its entire width by a longitudinal holding frame 3 attached to the outer wall surface of the building.

  On the front end edge of the saddle plate 2, a saddle plate 9 is mounted over the entire width. As shown in FIG. 11, the saddle plate 9 is in contact with the front end surfaces of all the plate materials 20, 21, and 22 constituting the saddle plate 2, and is fixed by screws 99, and the rear plate A first plate groove 95a between the front plate portion 92 and the front plate portion 92 and the rear plate portion 91; A bottom plate portion 94 is provided between the rear plate portion 91 and the projecting portion 93 for forming the second groove 95b. The upper and lower surfaces of the first and second groove grooves 95a and 95b are open, and the second groove groove 95b communicates with the hollow interior of the plate members 20, 21, and 22. As shown in FIGS. 9 and 10, both ends of each of the first and second ridge grooves 95 a and 95 b are opened, and rainwater flowing into the first ridge groove 95 a through the upper surface of the ridge plate 2. Is discharged to the outside through the openings 96, 96 at both ends, and the rainwater flowing into the second ridge groove 95b through the hollow interior of the ridge plate 2 flows down from the openings 97, 97 at both ends.

  However, in the scissors having the above-described configuration, the full length of the scissors becomes longer than necessary because the scissors 9 protrude beyond the front of the scissors 2 by the width w of the scissors 9 (FIG. 10). Moreover, since the gutter plate 9 includes the first and second gutter grooves 95a and 95b, the shape becomes large and the structure becomes complicated, and the cost of the gutter becomes high. Furthermore, since the upper surfaces of the first and second ridge grooves 95a and 95b are open, dust is likely to accumulate, and frequent maintenance and inspection are required. Furthermore, when dust accumulates in the second trough groove 95b and the passage of rainwater is blocked, rainwater seeps out from the gap 98 between the projecting portion 93 and the bottom surface of the trough plate 2, and other than the determined location. There is a problem that rainwater leaks from everywhere.

  The present invention has been made paying attention to the above-mentioned problems. By using a front edge plate having no structure corresponding to the first groove in place of the conventional flange, it is possible to reduce the size and simplify the structure. The purpose of this is to provide an inexpensive dredger that prevents rainwater from flowing down from places other than the designated location and that does not require labor and maintenance.

  The scissors according to the present invention include a scissor plate having a hollow portion between vertically opposed plate surfaces, and a holding frame that is attached to the outer wall surface of the building and that holds the rear end portion of the scissors plate in a state of projecting the saddle plate forward. And a front edge plate attached over the entire width so as to close the open front end face of the cover plate. The front edge plate is in contact with the open front end surface of the roof plate and has a vertical plate portion whose front surface is a guide surface that guides rainwater downward, and a top plate that is in contact with the top surface of the roof plate and has rain water in the vertical plate. And a horizontal plate portion serving as a guide surface leading to the guide surface of the portion. A concave portion extending over the entire width is formed on the lower inner surface of the vertical plate portion, and the concave portion is opposed to the open front end surface of the plate so that the upper portion of the opening portion communicates with the hollow portion of the plate plate, and the lower portion of the opening portion. Protrudes downward from the plate so as to communicate with the outside.

  In the dredge having the above-described configuration, rainwater collected on the upper surface of the saddle plate is guided to the front edge plate along the upper surface of the saddle plate, and passes through the guide surface of the horizontal plate portion of the front edge plate to the guide surface of the vertical plate portion. Led. Rainwater that reaches the guide surface of the vertical plate portion flows downward along the guide surface and falls from the lower end of the vertical plate portion. Rainwater that has entered the inside of the saddle plate flows through the hollow portion of the saddle plate toward the front end surface, flows from the opened front end surface into the concave portion of the vertical plate portion of the front edge plate, and then overflows from the concave portion to the vertical plate. It falls from the lower end of the part. Of the rainwater guided to the front edge plate through the top surface of the saddle plate, rainwater that has entered from the gap between the saddle plate and the horizontal plate portion of the front edge plate travels down along the inner surface of the vertical plate portion of the front edge plate. After flowing down and flowing into the recess, it overflows from the recess and falls from the lower end of the vertical plate. Thus, the rainwater that has flowed through the inside of the roof plate and the rainwater that has flowed through the top surface of the roof plate flow down from the same place, that is, from the lower end of the vertical plate portion of the front edge plate. Since the concave portion of the vertical plate portion is open on the inner surface side of the vertical plate portion, dust is difficult to collect, and even if dust adheres, it is washed away by rainwater.

  In the above-described configuration of the present invention, the overall plate may be a single hollow body, or may be configured by connecting a plurality of hollow plate members. When a plurality of hollow plate members are used, it is preferable to use an aluminum extrusion mold for each plate member in order to reduce the weight of the bag.

  In a preferred embodiment of the present invention, the concave portion of the vertical plate portion is open at both side ends, and the opening lower end edge of the concave portion protrudes so as to cover below the front end surface of the saddle plate. In this embodiment, the front end surface of the cover plate is in a blinded state in which the front end surface of the cover plate cannot be seen from below by the opening lower end edge of the recess, so that the appearance of the cover is prevented from being deteriorated.

  In the embodiment described above, the lower end surface of the vertical plate portion is inclined so that the rear side is lower than the front side. In this embodiment, the rainwater flowing on the upper surface of the vertical plate reaches the lower end of the vertical plate portion through the guide surface of the horizontal plate portion and the guide surface of the vertical plate portion of the front edge plate, and then below the vertical plate portion. It flows down to the outside together with the rainwater that has flowed through the inside of the slats from the inclined lower end of the end face.

  In a preferred embodiment of the present invention, the front end surface of the horizontal plate portion is formed as an obliquely upward tapered surface. In this embodiment, the rainwater guided to the front edge plate along the upper surface of the saddle plate rides on the guide surface from the tapered surface of the horizontal plate portion, so that the rainwater flow along the upper surface of the saddle plate becomes smooth.

  According to the present invention, since the front edge plate is attached over the entire width so as to close the opened front end face of the plate, there is no structure corresponding to the groove as in the conventional example, and the front of the plate is moved forward. The protruding portion can be eliminated. For this reason, the full length of the bag does not become longer than necessary, and there is no possibility that the structure becomes complicated. In addition, since there is no gutter groove with an open top surface, there is no risk of dust accumulation, and frequent maintenance and inspection is not required. Furthermore, even if dust adheres to the concave portion, the rainwater will wash away the dust, so that it is possible to prevent inconvenience due to the accumulation of dust, that is, the rainwater flowing from the gap portion other than the portion determined by blocking the rainwater passage.
