DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a valley of a horizontal roof,
The present invention relates to a structure when construction is performed using a valley cap and a waste plate.

[0002]

2. Description of the Related Art First, a conventional technique will be described with reference to FIG. This is a valley structure called lightning valley. When this is performed, a trough-shaped valley plate 5 made of a metal plate and extending from the ridge to the eaves is disposed in the valley. The valley plate 5 is obtained by temporarily bending the left and right sides toward the center line of the valley portion, then turning outward, and further bending both ends thereof in order to grip the horizontal roofing plates 4 on the left and right. The valley plate 5 is disposed in the valley portion, the left and right ends are fixed to the tark 6 using the suspension elements 7, and the roof shingles 4, 4 are gripped by the folded back of the valley plate 5 for construction.

[0003] It is also conceivable to make a part as shown in FIGS. FIG.
(A) is a perspective view of the valley cap 1, and (B) is an end view when cut along the AA line of (A). The valley cap 1 is formed by connecting left and right parts at the center as shown in FIG.
And a connecting portion 1d, in which the left and right sides of the flat portion 1a are folded inward.
1d, a step portion 1b in which the eaves side of the flat portion 1a is folded down, and a folded portion 1c in which the step portion 1b is bent toward the ridge side. The eave side of the valley cap 1 is formed in a V-shape at an angle corresponding to the slope of the roof. This valley cap 1 is attached to the roof shingles 4.4
The valley is constructed in combination with

A valley part 8 shown in FIG. 12 is also a part to be accommodated one by one, and is formed at an angle corresponding to the slope of the roof. And it is made so that it may not be necessary to cut the side-roof shingles 4 and 4 diagonally, and is made in a round shape in order to improve the beauty of the valley. Discarded plates are placed on the lower left and right sides of the valley component 8 and combined with the roofing shingles 4 by using a joint cap 9 or the like.

[0005]

In the case of the valley structure shown in FIG. 10, a long valley plate extending from the ridge to the eaves must be bent, and a large number of the valleys must be carried to the roof so as not to break. Instead, it took a skillful technique to grab the side-roofed shingle after folding it on the valley, and it was easy to get scratched. In addition, the design was impaired because the steps were eliminated by crushing the pieces for grasping.

In the case of the valley structure using the valley caps and valley parts shown in FIGS. 11A and 11B and FIG. 12, a large amount of valley caps and valley parts must be manufactured in accordance with the gradient at the site. Production was difficult and stock could not be made.

Further, the valley parts shown in FIG. 12 are extremely difficult to make, so that the roofing shingles do not have to be cut straight, so that the finished members are relatively large and the roofing shingles with the left and right roofing shingles are not required. The connecting parts and valleys were made to stand out, which sometimes spoiled the aesthetics.

In order to solve these problems, the present invention provides a valley cap that is relatively easy to manufacture, easy to construct, can cope with a certain degree of gradient, and is excellent in design. A valley structure using a plate is provided.

[0009]

According to the present invention, there is provided a valley structure comprising a horizontal roofing shingle, a valley cap, and a discarded plate as described below. First, the roofing shingle is provided with a face plate portion, an engaging portion formed on the eaves side of the face plate portion, and a locking portion formed on the ridge side of the face plate portion. The valley cap is provided with a flat portion, a connection portion in which both side edges of the flat portion are turned back to the back side substantially in parallel with the center line of the valley portion, and a step portion in which the eaves side of the flat portion is folded down. I have. And the eaves side of the flat part
It is formed on one side, and the step is formed on one surface.

The discarding plate is provided with a fixing portion and discarding plate portions formed on the left and right sides of the fixing portion, and the fixing portion is formed by folding the eaves side to form a folded portion. The length of the eaves-ridge direction is longer as the discarding plate part is closer to both side edges, and each eaves side is folded down to form a downward part. The descending portion extends downward from the folded portion of the fixed portion. Further, both side edges of the discarded plate portion are folded back to the surface side to form a rained portion.

The fixing portion of the discard plate having such a structure is fixed so as to be located at the center of the valley portion, and a horizontally-roofed roof plate adjacent to the left and right is placed thereon, and furthermore, a valley cap is covered and the horizontal-roofing portion is provided. Construction of the valley of the roof.

[0012]

[Effect] A valley cap having a flat portion whose eaves side is, for example, a square shape or a loose radius, and a stepped portion where the eaves side of the flat portion is folded down is used. By covering the face plate and covering the engaging part with a step,
The valley is constructed in accordance with a certain range of gradient.

[0013]

1 and 2 (a) and 2 (b), an embodiment of a member used in the present invention will be described. The valley cap 1 shown in FIG. 1 is made of a metal plate and has a rectangular shape as a whole. The valley cap 1 includes an elongated flat portion 1a, a step portion 1b obtained by folding the eaves side of the flat portion 1a, and a step portion 1b. It comprises a folded portion 1c bent to the side, and connecting portions 1d, 1d, which are folded back to the back side substantially right and left side edges of the flat portion 1a substantially in parallel with the center line of the valley portion.

Although the valley cap 1 is provided with a folded portion 1c, the reason that the folded portion 1c is provided and the stepped portion 1b is not cut off is that the end face is visible and the design is impaired and the cut end is rusted. This is to prevent it. Also, the folded part 1c
Thus, when the valley cap 1 is lifted by wind pressure or the like, the lower end of a folded-down portion 2d of the discarding plate 2 described later can prevent the valley cap 1 from coming off by pressing the folded portion 1c.

In the valley cap 1, the step portion 1b and the flat surface portion 1a are not formed so as to conform to the gradient or the angle of the valley portion. In order to cope with a certain gradient, the eave side is formed by one side. The present embodiment is characterized in that it has a flat portion 1a having a square shape and a step portion 1b obtained by folding the flat portion 1a at a substantially right angle.

FIG. 2A shows the discard plate 2, and FIG. 2B shows the insertion pieces 3.3. 2 (a) is longer than the working width of the horizontal roofing shingle 4, and has a fixing portion 21 for installing the insertion pieces 3 and 3, and a discarding plate portion 20 formed on the left and right sides of the fixing portion 21.・ It consists of 20. The left and right sides of the fixing portion 21 are folded back toward the upper surface to form the insertion portion 2c.
2c, which is a discarding plate portion 20 having bent portions 2a which are formed by bending the insertion portions 2c and 2c outwardly and further bending toward the center portion. Then, the left and right discarding plate portions 20, 20 are turned back portions 2b, 2b having both ends turned back to the surface side.
Is formed. In the case of this figure, the bent portions 2a, 2a are provided one by one on the left and right, but a plurality of bent portions may be provided, such as two or three on the left and right.

The eaves side of the fixed portion 21 is folded down at a substantially right angle to form a folded portion 2d, and the eaves side of the discarding plate portions 20 is also folded down at a substantially right angle to form a lowered portion 2e. . The eaves side of the discarding plate portions 20, which are left and right portions of the fixed portion 21, are formed obliquely, and the length of the eaves-ridge direction of the discarding plate 2 becomes longer toward the rain return portions 2 b. The lower portions 2e and 2e extend downward from the water than the lower portion 2d. In addition, the ridge side of the dumping plate 2 is raised or folded back to the eaves side.

This discarded plate 2 is made up of left and right horizontal roofing shingles 4.
It can be made on the same molding machine as the discarded plate normally used for the connection of No. 4. In the case of a normal discarding plate, the eaves side is cut straight after molding, but in the case of this embodiment, the eaves side of the discarding plate 2 is cut off in order to use it as a valley and finish as shown in FIG. The only difference is that it is cut into a substantially V shape along the shape of the part. So, without having to make a new molding machine,
By simply changing the cutting blades and the like, the discard plate 2 used for the valley structure according to the present invention can be made.

The insertion pieces 3.3 shown in FIG. 2B are formed by bending a single metal plate into a U-shape, and have lower surfaces 3b.
The portion b is formed to be slightly wider than the upper surface portions 3a. The lower surfaces 3b, 3b of the insertion pieces 3, 3 are inserted into the respective insertion parts 2c, 2c of the discarding plate 2, but the insertion parts 2c, 2c are inserted from above so that the insertion pieces 3.3 are hard to come off the discarding plate 2. And press down the insertion pieces 3.

Next, a method of constructing a valley using these components will be described with reference to FIG. The horizontal roofing shingle 4 laid on the roof in FIG. 3 has a face plate portion 4b and an engaging portion 4c obtained by folding down the eaves side of the face plate portion 4b and further bending it toward the ridge side.
And a locking portion 4a formed on the ridge side of the face plate portion 4b. Then, the roofing plates 4, 4 located on the left and right sides of the valley are cut diagonally along the center line of the valley, and the engaging portions 4c, 4c and the locking portions 4a, 4a are cut off. Pieces to be inserted into the insertion pieces 3 are formed by the face plate portions 4b. In addition, it is preferable that notches are formed at the respective ends of the engaging portions 4c and 4c 'and 4c' are bent slightly outward in accordance with the angle of the discard plate 2.

Then, the discard plate 2 into which the insertion pieces 3 and 3 are assembled is placed so that the fixing portion 21 is located at the center of the valley, and on the ridge side of the valley cap 1 installed in the lower step, Cover the folded part 2d of the discard plate 2
2b is fixed to a base material by being stopped with a hook or directly hitting with a nail or the like. Next, the face plates 4b and 4 of the left and right roofed roof plates 4.4 are attached to the insertion pieces 3.3 incorporated in the discard plate 2.
Insert b. At this time, each of the engagement pieces 4c '
c ′ is set along the folded portion 2 d of the discard plate 2.
The engaging pieces 4c 'and 4c' are also used for positioning when the step portion 1b of the valley cap 1 is applied, and when the width of the valley cap 1 is narrow, the engaging portions 4c and 4c of the horizontal roofing shingles 4.4 and 4 are used. The cut can also be considered as stretched out of sight.

Subsequently, as shown in FIG.
Is folded back to the eaves side, or cut into a V-shape along the ridge side shape of the side-roofed shingles 4 and bent to the eaves side. Then, the valley cap 1 is moved from the eaves side to the ridge side to insert the insertion piece 3.3 and the connection part 1d.
1d, the ridge side of the valley cap 1 is fitted to a place where the ridge side of the face plate portions 4b is turned back to the front side in the side-roofed roof plate 4.4. This procedure is repeated to construct the valley.

When the valley cap 1 according to the present invention is applied by the above-described method, the applied state is as shown in FIG. The valley cap 1 used in the valley structure of the present invention described with reference to FIGS. 1 to 4 does not form the eaves side of the flat portion 1a in a V-shape along the shape of the valley portion, but has an elongated flat portion 1a. The eaves side is formed by one side of a quadrangle, the left and right side edges are formed substantially parallel to the center line of the valley, and the eaves side of the flat portion 1a is folded down at a substantially right angle to form a step portion 1b.

FIG. 5 shows a state in which the shape of the eaves side of the valley cap 1 shown in FIG. 1 has been changed, and the valley cap 1 has been placed over the roofing shingle 4 to form a valley. This valley cap 1
Also, instead of forming the eaves side of the flat portion 1a in a V-shape along the shape of the valley portion, the eaves side of the elongated flat portion 1a is formed by projecting the eaves side to form a loose rounded side, and the left and right sides are formed. The edge is formed substantially parallel to the center line of the valley, and the eave side of the plane portion 1a is folded down at a substantially right angle to form a step portion 1b. FIG.
FIG. 6 is an explanatory diagram of a discard plate 2 used in FIG. 5.

FIG. 7 is an explanatory view of a construction state according to another embodiment of the valley cap. As shown in this figure, the eave edge of the flat portion 1a of the valley cap 1 is formed by the left and right engaging portions 4c.
It draws a gentle arc that continues to. The left and right side edges of the flat portion 1a may be formed substantially parallel to the center line of the valley portion, and the eaves side of the flat portion 1a may be folded at a substantially right angle to form the step portion 1b to form the valley portion. Conceivable. Fig. 8 (a) (b)
FIG. 3 is an explanatory view of an embodiment of a discard plate 2 used when applying the valley cap 1 having such a shape. (A) shows FIG.
The folded-down portion 2d is formed in a concave round shape along the shape of the step portion 1b of the valley cap 1.
(B) is formed by shifting the position of the folded-down portion 2d toward the ridge in accordance with the most recessed point of the step portion 1b of the valley cap 1 shown in FIG.

FIG. 9 shows another embodiment of the discard plate 2, in which both ends of the descending portions 2e are united.

The valley cap 1 in FIG. 11 and the valley component 8 in FIG.
In each case, each part is made at an angle suitable for the site. Therefore, if one valley cap 1 or valley part 8 is used in a valley part with a greater angle, the roof shingle 4.4 cannot be constructed. A gap is formed between the engaging portions 4c of the fourth member 4 and the eaves side of the valley cap 1 or the like. However, since the valley cap 1 according to the present invention has the configuration as described above, it can cope with a certain range of angles.

The shape of the valley has a V-shape that opens toward the eaves side, and it is easy to think that the members used for the valley can be formed at an angle corresponding to the shape. A feature of the present invention is that the shape is not necessarily made to follow the shape of the valley. The valley cap 1 used in the present invention has an elongated flat portion 1a, the eaves side of which is constituted by, for example, one side of a square shape or a loose round shape, and the left and right side edges thereof are substantially parallel to the center line of the valley portion, The valley cap 1 is formed by folding the eaves side at a substantially right angle to form the step 1b.
The connection between the roof shingles 4 and the left and right roof shingles 4 was flexible, and the valley had a natural appearance.

[0029]

In the case of the conventional valley structure, a long valley plate from the ridge to the eaves must be bent and transported to the roof in large numbers without breaking it. Skill is required to bend the folded back of the valley board and then grasp it, and it is easy to be scratched, and the design is impaired because the step is eliminated by crushing the grout for grasping, but the valley according to the present invention In the case of a valley structure using a cap, the construction is easy, there is no fear of damaging, and the design is not impaired.

In the case of a conventional valley structure using valley caps and valley parts, mass production is difficult and inventory cannot be made because the valley caps and valley parts must be made in accordance with the gradient at the site. The valley cap according to the present invention can cope with an angle within a certain range, and can be mass-produced or stocked.

Furthermore, the conventional rounded valley parts are extremely difficult to make, and the roofing shingles do not have to be cut straight, so that the finished members are relatively large and the left and right roofing shingles are relatively large. Although the connection portion and the valley may be noticeable, and the beauty may be spoiled, the valley cap according to the present invention has an elongated flat surface shape on the surface, and the left and right sides of the valley center line. The valley structure has a simple and comfortable finish, which is easy to make.
