Abstract

(57) [Summary] [Purpose] Even if the dormer's roof shape is flattened, rainwater in the dormer portion can be reliably discharged without impairing the external design of the dormer tip. [Structure] A dormer 2 having a flat roof is attached to a part of the roof 1. A front decorative material 3 having a trough portion 3A formed inside is attached to the front end surface of the dormer roof 21, and joined to the vertical tubular front decorative material 4 attached to both front surfaces of the dormer.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water storage structure in a dormer provided on a part of the roof for daylighting and ventilation, or for making the exterior design more beautiful.

[0002]

[Prior art]

 In some cases, a so-called dormer, which is an auxiliary roof for projecting light or ventilation, is projected on part of the roof. As shown in Fig. 4, the conventional dormer has an inverted V-shaped roof so that the center is high and the sides are low, as shown in Fig. 4, so that rainwater will naturally flow down due to the slope of the dome when it rains. I am doing it.

[0003]

[Problems to be solved by the device]

 However, due to the variety of exterior designs, the shape of the dormer roof is not limited to the inverted V shape, but it is sometimes better to make the dormer roof flat rather than the overall roof design. In this case, it is difficult for rainfall on the dormer roof to flow down naturally, and rainwater may collect at the tip of the dormer. Then, the rainwater collected at the tip of the dormer will enter the dormer. In order to prevent this, it becomes necessary to attach rain gutters to the dormer as well as eaves gutters, which may impair the exterior design of the dormer.

An object of the present invention is to ensure that even if the dormer has a flat roof shape, rainwater in the dormer portion can surely flow out without impairing the appearance design at the tip of the dormer.

[0005]

[Means for Solving the Problems]

 The present invention was made in order to achieve the above-mentioned object, and a dormer having a flat dome roof is attached to a part of the roof, and a front decorative material in which a gutter is formed on the inner end of the dome roof. The gist is that it is attached to the front side of the vertical dome and is attached to the front of both sides of the dormer.

[0006]

[Action]

 Even if the dormer has a flat roof shape, the rainwater flows down toward the tip of the dormer and flows into the front decorative material attached to the tip of the domer. Since the front decorative material has a gutter function and has a water gradient so that it flows to both sides, rainwater flows to both sides at the tip of the dormer, and then is arranged vertically on both end faces. It flows down inside the front decorative material and flows out onto the roof. For this reason, even if the exterior design of the dormer has a novel flat shape that has never existed before, rain can be surely performed.

[0007]

【Example】

 Hereinafter, the water storage structure in the dormer of the present invention will be described with reference to the illustrated embodiment. In the figure, reference numeral 1 denotes a roof of a building, which is provided with a required roof slope, and a dormer 2 is attached to a part of the roof 1 at a predetermined position. This dormer 2 may be installed as a simple roof design, or for lighting and ventilation.

The dormer 2 has a flat roof 21. A wide and small dance 22 provided at the front end of the dormer roof 21 is integrally provided with a water partition 23, and a nose plate 24 is provided at the tip of the dormer. The dormer ceiling material 25 is fixed to the nose plate 24 as needed.

The front decorative material 3 is attached to the dormer nose plate 24. As shown in detail in FIG. 1, the front decorative material 3 has a support piece 32 projecting over the entire length of the front plate 31 on the inner surface of the front plate 31 having a shape and size that covers the front surface of the dormer nose plate 24. An engaging piece 33 along the dormer nose plate 24 is integrally provided at the front end of the supporting piece 32, and an upper piece 34 is formed on the upper portion of the front plate 31 by bending so as to slightly cover the tip of the dormer roof. Therefore, the front decorative material 3 has a trough portion 3A having a U-shaped cross section formed by the front plate 31, the support piece 32, and the upper engaging piece 33 inside the front decorative material 3 so that it flows down from the front end of the dormer roof. Rainwater is received at this gutter 3A.

Further, when the front decorative material 3 is attached to the dormer nose plate 24, there is a water gradient so that rainwater that has fallen on the dormer roof is more likely to come from the gap between the wide dance 22 and the upper piece 34 at the tip of the dormer. It is made to flow into the trough part 3A inside the material and flow down to both sides of the dormer.

[0012] On both front sides of the dormer 2, vertical cylindrical decorative materials 4 are arranged, the front decorative materials 3 and 4 are abutted against each other, and rainwater flowing down in the trough 3A is vertical. The front surface is made to flow into the decorative material 4 and naturally flow downward. By attaching the lower end of the front decorative material 4 with a small gap between the front decorative material 4 and the roof 1, rainwater is naturally discharged onto the roof.

[0012]

[Effect of device]

 In the water storage structure of the dormer of the present invention, a dormer with a flat dormer roof shape is attached to a part of the roof, and a front decorative material with a gutter inside is attached to the front end surface of the dormer roof, and both sides of the dome are attached to the front. Since they are arranged so as to be joined to the attached vertical tubular front decorative material, even if the dormer roof shape is flat, rainwater can be naturally discharged without accumulating on this roof part, And it can have a novel shape.
