Abstract

PURPOSE:To prevent cracks from being generated by coloring half a section in the width direction with brightness higher than that of the other half section, on the internal surface of a rain-water gutter with an opening upper surface, to direct the side with higher brightness, to the north side, and by reflecting strong sunbeams from the south side, to reduce the rise of a temperature. CONSTITUTION:On the internal surface of the half section in the width direction, of the rain-water gutter main-body 1 of a U-type cross-sectional-area or a C-type cross-sectional-area, a bright color layer 2 with brightness higher than that of the other half section is formed. After that, when the gutter 1 is fitted on a structure, then the side of the layer 2 is set roughly to the north side, and strong sunbeams from the south are reflected. As a result, temperature difference between sections which the sunbeams are applied to, and sections which no sunbeams are applied to, is diminished, and the deformation can be reduced, and cracks and leakage water can be prevented from being generated due to the deformation.

Description

[Detailed description of the invention]

■Industrial application field】 The present invention relates to gutters such as valley gutters and eaves gutters.

[Conventional technology]

Valley gutters 5 and eaves@6 are used as gutters to catch and drain rainwater from the roof. Fig. 3(a) shows an example in which the valley @5 is attached at the valley part 8 of the roof 7, and Fig. 3(b) shows an example in which the eaves 4i6 is attached at the eaves 9 of the roof 7. It is.

[Problem N that the invention attempts to solve]

But valley 4 installed like this! I5 and eaves gutter 6
As shown in Figure 3 (a) and (b), the inner surface of the northern half is easily exposed to sunlight, while the southern half is in the shade and is difficult to receive sunlight. As the difference in temperature rise between the north and south sides becomes larger, the difference in length between them becomes larger, and as shown in Figure 4, valley gutter 5 and eaves gutter 6
Curving deformation will occur. As a result of this repeated deformation, cracks may occur in the valley gutter 5 and the eaves gutter 6, leading to water leakage. In particular, since the valley 415 is fixedly attached and cannot freely extend, it is likely to be distorted, and cracks are likely to occur in the valley gutter 5 due to the repeated effects of this distortion. The present invention has been made in view of the above points, and it is an object of the present invention to provide a gutter that can reduce the occurrence of cracks due to deformation caused by sunlight irradiation.

[Means for Solving the Problems 1] A gutter according to the present invention has an inner surface of a gutter body 1 formed in a cross-sectional shape with an open top surface, so that approximately half of the widthwise portion thereof is brighter than the other approximately half portion. It is characterized by being formed in a high color. In the present invention, since approximately half of the inner surface of the gutter body 1 in the width direction is formed in a color that is brighter than the other approximately half portion, the color that is brighter is By installing it so that approximately half of the part formed on the wall faces north, due to its brightness, even if sunlight shines on the dark colored part, it will reflect the sunlight and the temperature of the part exposed to sunlight will not rise much. This results in reducing the occurrence of deformation.

【Example】

The present invention will be explained in detail below with reference to Examples. The valley Is and the eaves 416 are formed by processing a plate material formed by laminating a soft polyvinyl chloride coating layer 12. )(b)
As shown in the figure, the cross-sectional shape is formed by bending into a substantially F-shape or a substantially C-shape with an open top surface. The inner surfaces of the valley gutter 5 and the eaves gutter 6 are finished so that approximately half of the widthwise portion thereof has a brighter color than the other approximately half portion. To finish approximately half of the part in a bright color, apply a light-colored paint to this part or laminate a light-colored acrylic resin film to the coating layer 12 as shown in Figure 2. This can be done by forming a light color layer 2 on the surface.
It may be formed when manufacturing the valley II5 and the eave 1a6, or after the valley II5 and the eave 1a6 are attached to the house. The coating layer 12 has a brightness of 10, such as black.
If the light color layer 2 is formed in a dark color with a brightness of about 80 to 90, such as beige, cream, or white, the inner surface of the valley 1a5 and eaves gutter 6 can be It can be formed with a large difference in sound sleep between approximately half of the direction and approximately the other half. $1 The valley gutter 5 formed as shown in Figure (a) is as shown in Figure 3 (,
), it is installed by fixing it to the valley 8 of the roof 7 with nails 30, etc., and the eave @ 6 formed as shown in Fig. 1(b) is installed as shown in Fig. 3(b). ), it is attached to the eaves 9 of the roof 7 by supporting it with a retainer 14 or the like. In the #IIJ3 figure, 15 is the am plate. These valley gutters 5 and eaves gutters 6 are installed so that the half side on which the light-colored layer 2 is provided faces substantially north. In the valley 415 and eaves gutter 6 installed in this way, since strong sunlight during the day is irradiated from the south side, the valley 1a5 and eaves gutter 6 have an inner surface on the north half as shown by the arrow. It is easy to get sunlight, and the southern half is in the shade and difficult to get sunlight, so it is a valley! The effect of sunlight on i15 and eaves@6 will be greatly different between the northern and southern parts. However, since the light-colored surface layer 3 is formed on the inner surface of the valley 415 and the northern half of the eaves gutter 6, even if sunlight hits this part, it is easily reflected, and the temperature rises in this part that is strongly exposed to sunlight. You can suppress it. Therefore, it is possible to suppress the difference in width between the north half and the south half of the valley gutter 5 from increasing, and to suppress the occurrence of curved deformation of the valley 4115 and the eaves @ 6 as shown in FIG. This can be achieved by preventing water leakage by preventing cracks caused by distortion. [Effects of the Invention] As described above, in the present invention, the width direction of the inner surface of the gutter body is Since the half part is formed in a color with higher brightness than the other approximately half part, by installing it so that the approximately half part formed in a high brightness color faces north, this brightness ^ Even if sunlight shines on a dark-colored area, it reflects the sunlight and prevents the temperature of the exposed area from rising too much, reducing the difference in temperature rise between areas exposed to sunlight and areas that are not exposed to sunlight. This can reduce the occurrence of deformation, and can prevent water leakage from occurring due to cracks caused by this deformation.
