Abstract

PROBLEM TO BE SOLVED: To prevent the leak by counter-flow water with a simple means by adhering a counter-flow preventing rail formed in a height close to the reverse side of a tile laid along a valley plate body on the upper surface on both sides of the valley plate body formed by use of a metal plate. SOLUTION: A valley plate body 1 formed by cutting a galvanized iron plate or the like in a necessary length is laid by being fixed to a sheathing roof board 4 by a nail 6. A counter-flow preventing rail 5 formed in a long bar by use of synthetic resin material is cut according to the length of the laid valley plate body 1 and stuck to the upper surface on both sides of the valley plate body 1 through an adhesive filled in an adhesive groove, and rail tiles 3 are laid along both sides of the roof valley formed by the sheathing roof board 4. Even if the weight of a worker walking near the roof valley is added in working, or the sag of tiles is caused by a long-term use, the counter-flow preventing rail 5 is never crushed. Accordingly, the great factor of leak is solved, and the leak can be prevented with a simple means.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valley plate used for a roof valley and a method of laying the valley plate.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional valley plate used for a roof valley is provided with a bent portion 1a in which both sides of a valley plate body 1 are bent upward by about 1 cm, thereby preventing rain leakage. It was not going to happen. That is, the rainwater flowing through the valley plate body 1 is covered with the roof tiles 3 along the valley plate body 1.
In order to prevent backflow on the back surface of the valley plate body 1, a bent portion 1a is provided on both sides of the valley plate main body 1 to prevent backflow water.
Further, in order to fix the valley plate main body 1 to the base plate 4, the mounting bracket 2 is hooked on the bent portion 1 a and fixed by the nail 6.

[0003]

In the conventional valley plate used for the roof valley, both sides of the valley plate body 1 are bent upward as described above. Therefore, the rust prevention treatment such as plating or painting of the valley plate material was damaged during bending, and the valley plate material was corroded, causing a leak of rain. For this reason, a copper plate resistant to corrosion is sometimes used, but the use of a copper plate has increased the construction cost. Further, if the valley plate main body 1 is fixed to the base plate 4 by nailing inside the valley plate main body 1, there is a risk of rain leaking from the hole of the nail. Therefore, as shown in FIG.
Since the mounting bracket 2 is hooked on the bent portion 1a and nailed, it is troublesome and the construction cost is high.

Further, during construction, the bent portions 1a on both sides of the valley plate main body 1 are crushed by the weight when an operator walks in the vicinity of the roof valley, or by the slack of the tile generated over many years. As a result, the function to prevent backflow water was lost, and this was a major factor in rain leakage.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a method of laying a valley plate for a roof valley or a valley plate for a roof valley, which can prevent rain leakage due to backflow water by simple means. The purpose is to provide.

[0006]

In order to achieve the above object, in a valley plate for a roof valley according to the present invention, a valley plate body formed by using a metal plate is provided on both upper surfaces of the valley plate body along the valley plate body. A synthetic resin backwater prevention bar formed at a height close to the back surface of the tile to be roofed was bonded.

In addition, after laying a valley plate body formed using a metal plate on a roof valley, the back surface of a tile that is laid along both sides of the valley plate body is placed on both upper surfaces of the laid valley plate body. The backwater prevention bar made of synthetic resin formed at a height close to the height is bonded.

[0008]

(Embodiment 1) Embodiments of the present invention will be described below with reference to the drawings. In FIG.
Reference numeral 4 denotes a field plate forming a roof valley, and reference numeral 3 denotes a roof tile laid along both sides of the roof valley. Reference numeral 1 denotes a valley plate main body, which is formed by cutting a strip of galvanized iron plate or copper plate to a required length. The valley plate body 1 is laid on the base plate 4 with nails 6. Reference numeral 5 denotes a backwater prevention bar formed of a synthetic resin material such as a vinyl chloride resin or a polyethylene resin into a long rod shape. The cross-sectional shape is formed as shown in FIG. That is, 5a is an adhesive surface, and the width dimension W is about 2 cm.
Thus, an adhesive groove 5b is provided at the center. Reference numeral 5c denotes a top portion, and a height H from the bonding surface 5c to the top portion 5c is about 1.3 cm. The intermediate portion 5d is formed to be thin so as to generate elasticity when the top portion 5c is pressed.

The above-mentioned backwater prevention bar 5 is adhered to the upper surface on both sides of the valley plate main body 1 laid on the base plate 4 to form a valley plate for a roof valley. In this case, the backwater prevention bar 5 is cut in accordance with the length of the valley plate main body 1 laid, and the adhesive groove 5b is filled with an adhesive and attached to both upper surfaces of the valley plate main body 1.

(Embodiment 2) In Embodiment 1 described above, the method of laying the valley board main body 1 on the base plate 4 and then bonding the backwater prevention bar 5 thereto is described. When the laying is short, the backwater prevention bar 5 may be bonded to the valley plate body 1 in advance, and the valley plate for the roof valley may be laid. That is, in FIG. 2, reference numeral 1 denotes a valley plate main body, which is the same as the valley plate main body 1 of the first embodiment, and is cut in accordance with the length to be laid. Reference numeral 5 denotes a backwater prevention bar, which is similar to the backwater prevention bar 5 of the first embodiment, and is cut in accordance with the length of the cut valley plate main body 1. The backwater prevention bar 5 is bonded to the upper surface on both sides of the valley plate main body 1 to form a valley plate for a roof valley, which is laid on the field board 4.

(Embodiment 3) In the above embodiment, the backwater prevention bar 5 has a special cross-sectional shape as shown in FIG. 3 (a). As shown, a similar effect can be obtained even with a simple shape. In particular, when it is difficult to use standard sized valley plates for roof valleys, as in the case of emergency repairs of rain leaks, select materials with appropriate dimensions from commercially available synthetic resin rods. May be.

[0012]

Since the present invention is configured as described above, it has the following effects.

Since it is not necessary to provide a bent portion in the valley plate main body, problems such as peeling of plating or damage to rust prevention treatment such as painting caused by the bent portion of the conventional valley plate body are solved.

[0014] Further, mounting brackets for mounting the valley plate main body are not required, and the construction cost can be reduced.

[0015] Further, during construction, even if the weight is applied when an operator walks near the roof valley, or even if the slack of the tile that occurs for many years has occurred, it is possible that the backwater prevention bar is crushed. Absent. Therefore, a major factor of rain leakage is eliminated.
