Description

[Detailed description of the invention] Industrial field of application The invention relates to a sheet metal eave water receiving plate that is attached to the eaves side of a roof by placing it on the wall surface of the upper floor wall and the roof surface of the lower floor roof. It is something.

PRIOR ART In general houses, eaves drainage is installed to prevent rainwater from directly dripping from the eaves by placing it on the wall surface of the upper floor wall and the roof surface of the lower floor roof, as shown by circles in Figure 6. A receiving plate is attached.

Conventionally, as shown in FIG. 7, this eaves water receiving board has a wall fixing plate part 1 in the form of an upright plate that is inserted and fixed inward from the outer wall P of the upper floor wall part, and the wall fixing plate part 1.
A roof fixing plate part 2 which is bent forward in a substantially right angle direction from the lower end side and attached to the upper side of the cap and placed on the roof plate R of the downstairs roof, and a roof fixing plate part 2 on the eaves side of this roof fixing plate part 2. A concave groove part 3 formed diagonally downward from the front edge where the groove part 3 is located, is disposed in front of the eaves, and is sloped downward from the lower end side located on the eaves side of the wall fixing plate part 1, and the lower end side is open.
and a rising plate part 4 which is formed to form one wall surface of the recessed groove part 3 and whose one end side is in contact with the front end side of the wall fixing plate part 1. The eave water receiving plate is bent and formed using a single sheet metal material, and the corner 5 between the wall fixing plate part 1 and the rising plate part 4 is the front edge of the wall fixing plate part 1, and the rising plate Part 4
Usually, they are assembled by cutting out one edge of each and fixing them together by welding.

However, this not only results in redundant cut-out parts, but also requires time and effort to assemble, and there is also a risk that the welded parts will be exposed to wind and rain and corrode over time.

Problems to be Solved by the Invention The object of the present invention is to provide an eaves water receiving plate that is formed by bending the entire plate from a single plate without providing any welded parts.

Means for Solving the Problems The eaves water receiving board according to the present invention includes an upright plate-shaped wall fixing plate portion that is placed against the wall surface of the upper floor wall, and a wall fixing plate portion that is approximately perpendicular to the bottom edge of the wall fixing plate portion. A roof fixing plate part that is bent forward in the direction and placed against the roof surface of the downstairs roof, and a roof fixing plate part that is stepped down from the front edge located on the eaves side of the roof fixing plate part and placed on the eave side of the wall fixing plate part. A recessed groove section is provided on a downward slope from the lower end side and is open at the lower end side, and one wall surface of the recessed groove section is formed upright, and one end side is in contact with the front end side of the wall fixing plate, thereby forming a corner. Each part is shaped and cut into a continuous single board, and the remaining part located between the front edge of the wall fixing plate and one end of the rising plate is cut out. Fold the intersection of each end side equiangularly as a folding allowance for two sheets, and then bend this folded folding allowance to the plate surface side of the wall fixing plate or rising plate. It is configured by providing the corner portions.

Function: With this eaves water receiving board, the front edge of the wall fixing plate and one end of the rising plate are continuous with a bending allowance that is bent into two equiangular layers without cutting, and the bending allowance is used to connect the bending allowance to the wall fixing plate. Alternatively, since the corner portions are connected and formed by bending and stacking the rising plate portions on the plate surface side, the entire plate can be formed by bending a single sheet metal material.

Embodiments The following description will be given below with reference to FIGS. 1 to 5.

This eaves water receiving plate is made by bending and forming a sheet metal material, and as shown in FIG. A roof surface fixing plate part 11 that is curved and a groove part 12 that is formed downward from the front edge of the roof surface fixing plate part 11 located on the eaves side.
and a rising plate portion 13 that is formed to form one wall of the groove portion 12.

The wall fixing plate 10 is placed on the inside of the upper floor wall as shown in FIGS. 5 and 6, and
The roof surface fixing plate part 11 is formed so as to receive rainwater flowing downward through the roof surface by being placed against the roof surface of the downstairs roof.

As shown in FIG. 2, the groove portion 12 is formed by a substantially triangular side plate 12a that is bent downward at right angles from the front edge of the roof fixing plate 11, and the side plate 12a and the wall fixing plate 10 are By forming a groove bottom with a rectangular plate 12b continuous from the lower end side located on the eaves side, the groove bottom is continuously formed in a downward slope with an open lower end side. In addition, the rising plate portion 13
and the wall surface fixing plate part 10 are formed continuously through bending allowances 14 and 15 which are bent into two equiangular sheets, and the bending allowances 14 and 15 are overlapped and bent to form a wall surface as shown in FIGS. 3 and 4. The wall fixing plate part 10 and the rising plate part 1 are bent toward the plate surface side of the fixing plate part 10.
A corner portion 16 is formed by continuously bending 3 and 3. These double bending allowances 14 and 15 are integrally joined to the wall fixing plate part 10 by providing a bending allowance 17 from one of the upper edges and bending it from the upper edge of the wall fixing plate part 10 toward the front side. can.

The sheet metal material for bending and forming the eaves water receiving plate is cut into a single sheet to form a shape, as shown in FIG.
They are a wall fixing plate part 10, a roof fixing plate part 11,
In addition to the concave groove portion 12 and the upright plate portion 13 consisting of the side plate 12a and the bottom plate 12b, the remaining plate surface portion located between the front edge of the wall fixing plate portion 10 and one end side of the upright plate portion 13 is folded. It is sufficient to form the bending allowances 14 and 15 into shapes, and these bending allowances 14 and 15 can be formed by folding the intersection points O of each end at equal angles and continuing the bending without cutting. . In addition, this cut-out board can be bent inward along the fold line shown by the chain line in the figure, and bent outward along the fold line shown by the dashed-dotted line to form an eaves water receiving plate having a predetermined three-dimensional shape. can do.

In the eaves water receiving plate constructed in this manner, the corner portions of the wall fixing plate portion 10 and the rising plate portion 13 are formed continuously by bending the bending allowances 14 and 15, so that a single plate is bent. This allows the whole to be assembled and molded without providing any welding points or the like in any part.

Effects of the invention As described above, according to the eaves water receiving board according to the present invention, it can be formed by bending the entire board from a single plate without providing a notch, so it can be formed at low cost and with high durability in use. This is what makes it possible.
