As shown in FIG. 2, this enclosure frame plate for rain is used to form an opening C provided in a square on a construction surface such as a roof in order to install an assembly S such as a skylight or a roof fan on a roof or the like. Used to perform

[0009] The enclosure frame plate for rain is formed by using a metal flat plate 10 such as stainless steel as shown in FIG. 3A. As shown in FIG. 3B, the single flat metal plate 10 is folded into two sheets and bent and formed as an overlap bent plate 11. The overlapping bent plate 11 is folded into two at the desired position of the metal flat plate 10 by considering the rising dimension of the rising enclosing plate portion 1, the depth width of the enclosing plate portion 1 and the overhang width of the fitting fixing plate portion 2. Just do it.

The notches 13 and 14 are formed in the overlapping bent plate 11 from the center of the bent side 12 toward the oblique side.
Into a straight line. These notches 13 and 14
Are provided such that the inner ends 13a and 14a are spaced apart from each other by a length corresponding to the length between the corners of the opening C described above. Further, depending on the cut portions 13 and 14, the cut bent pieces 15 are provided within the interval between the cut portions 13 and 14. As shown in FIG. 3 c, the cut-and-bent piece 15 reinforces the fitting fixing plate 2 together with the base side of the rising surrounding plate 1 by bending it into the rear surface side of the overlapping bending plate 11 which becomes the fitting fixing plate 2. . Further, the inner space of the rising surrounding plate portion 1 is formed by bending the cut bent piece portion 15.

As shown in FIG. 3D, one side 11a of the overlap bending plate 11 has inner ends 13a and 14a of the cuts 13 and 14, respectively.
Is formed in the perpendicular direction from the other 11b along the straight line connected by the arrow to form the rising plate portion 1b. The rising plate part 1
The right and left sides 16a and 16b of the b are bent in the direction perpendicular to the bent side 12 of the overlap bending plate 11 from the inner end positions of the cuts 13 and 14 as shown in FIG. It is formed as portions 1b and 1c. The lower sides of the left and right side plate portions 1b and 1c are located near each end 12 of the bent side 12.

Bend along a straight line toward 4a. The upright enclosing plate portion 1 can be bent into a U-shape by bending each of the shift bending portions 17a and 17b, and the shift bending portions 17a and 17b can be bent.
Since the base plate 17b is overlaid and bent on the plate surface of the other side 11b to be the application fixed plate unit 2, the base side of the rising surrounding plate unit 1 can be reinforced together with the cut-off bent piece unit 15.

When the rising enclosing plate 1 is bent and formed,
As shown in FIG. 3f, triangular pieces 18a, 18b are left at the lower edges of the left and right side plate portions 1b, 1c so as to be located closer to the cuts 13, 14 from the bent portions 17a, 17b.
The triangular pieces 18a, 18b are connected to the left and right side plates 1b, 1c.
By bending in such a manner as to abut on the inner side surface from the lower end edge of the opening C, the inner space of the rising surrounding plate portion 1 can be formed in conformity with the edge of the opening C. Also, the triangular pieces 18a,
Reference numeral 18b denotes a cut-bend side portion 15, and shift-bend portions 17a and 17b.
At the same time, the base side of the rising surrounding plate portion 1 can be reinforced. In addition,
The above-described bending of the cut and bent piece portion 15 is performed by the triangular side portions 18a,
18b.

[0014] When the rain-end enclosing frame plate constructed as described above is developed into a single sheet, only cut lines corresponding to the cut portions 13 and 14 are present as shown in FIG. There is no useless portion due to cutting and removing. In addition, the cutting bend side portion 15, the approach bending portion 17a,
17b and the triangular piece portions 18a and 18b are formed at the inner ends 13 of the cut portions 13 and 14 so as not to leave a gap or the like at the base side where rainwater or the like oozes out into the inner space side of the rising surrounding plate portion.
a and 14a are bent and formed as a base point, so that the rising surrounding plate portion 1 and the fitting fixing plate portion 2 can be continuously bent and integrally formed as a rain-covered surrounding frame plate.

When the skylight is installed on a roof, for example, this rain-shrouding enclosure frame plate is used as a roof base plate R as shown in FIG.
Is used to assemble the surrounding frame F surrounding the rim of the opening C provided in the opening. In the rain-closing enclosure frame plate, the lower edge of the rising enclosure plate portion 1 is aligned with the three sides of the opening C on the inner space side, and the applied fixing plate portion 2 is grounded on the surface of the roof base plate R. Thereby, it is arranged on the opposite side of the rim via the opening C. L-shaped metal plate members 3 and 4 composed of rising plate portions 3a and 4a and fitting fixing plate portions 3b and 4b are arranged on both sides of each of the rain-closing enclosing frame plates so as to overlap each other. By fixing the fixing plate portions 2, 3b, 4b to be grounded to each roof base plate R to the roof base plate R by nailing or the like, it is possible to assemble the enclosure F for rain-closing. The enclosing frame F for the rain breaks is provided with the framework of the assembly S outward so as to prevent rainwater or the like from seeping into the opening C side from the lower part of the framework of the assembly S such as a skylight installed on the roof. Used for positioning, fitting and fixing.
