[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the eaves gutter structure according to the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a cross-sectional view showing a state where the eaves gutter 10 of the present embodiment is attached to a nose cover 14 at the eaves via an attachment 12. The eaves gutter 10 is formed to have a concave cross section, and has an eaves gutter portion 10A for flowing rainwater on its bottom surface and a design surface 1 on its left side surface.
0B and a mounting surface 10C are integrally formed on the right side thereof.

The eaves gutter 10 is preferably made of resin from the viewpoint of rust prevention. In the present embodiment, a composition containing a vinyl chloride-based polymer and fibrous material, preferably this composition,
Further, a composition containing a copolymer composed of a polymer chain that is miscible with the vinyl chloride polymer and a polymer chain that is immiscible with the vinyl chloride polymer, and has a coefficient of linear expansion. 4 × 10 ^-5 / ° C or less, flexural modulus 500 kg /
The eaves gutter 10 is formed from a composition of not less than mm ² . As a result, the eaves gutter 10 is superior in the amount of expansion and contraction due to temperature changes, the amount of deformation at high and low temperatures, and the strength, as compared with a general vinyl chloride eaves gutter. Further, it is preferable to form the eaves gutter 10 using a composition having a coefficient of linear expansion of 3 × 10 ⁻⁵ / ° C. or less, because the influence of a temperature change can be particularly reduced.

Further, the composition has a heat distortion temperature of 75 °.
C-85 ° C, which is much higher performance than general vinyl chloride resin gutter products, can reduce thermal deformation due to temperature changes, etc. This is unnecessary, which is extremely advantageous in terms of simplification of the structure, appearance and cost. Furthermore, while the general composition made of vinyl chloride is extremely brittle at low temperatures, the composition also has the characteristic that the decrease in strength is extremely small even at low temperatures.

When the conventional hanging metal fitting is used, the load of the eaves gutter concentrates on the hanging metal fittings. On the other hand, in the present embodiment, the load of the eaves gutter 10 is evenly and uniformly applied to the continuous fitting 12. Since they are dispersed, the strength and deformation are uniformly suppressed. A reinforcing plate 16 is provided inside the eaves gutter 10. A plurality of the reinforcing plates 16 are arranged at predetermined intervals in the longitudinal direction of the eaves gutter 10. In the method of mounting the reinforcing plate 16, first, the space between the design surface 10B of the eaves gutter 10 and the mounting surface 10C is widened, and the reinforcing plate 16 is inserted inside the eaves gutter 10. Next, hook portions 18, 1 formed above and below the right end of the reinforcing plate 16 are formed.
8 is engaged with hook portions 20, 20 formed inside the mounting surface 10 </ b> C of the eaves gutter 10. Next, the convex portion 22 formed on the left end of the reinforcing plate 16 is connected to the design surface 10B of the eaves gutter 10.
Is engaged with the groove 24 formed to protrude inward. By repeating this procedure, a large number of reinforcing plates 16, 16,.
Can be attached to the eaves gutter 10. This reinforcing plate 16
Like the eaves gutter 10, it is preferably made of resin, and more preferably made of the same composition as the eaves gutter 10.

On the other hand, the mounting member 12 is formed in a long plate shape, and is mounted on the nose cover 14 with screws (not shown) along the mounting direction of the eaves gutter 10. The cover of the nose 14
Is fixed to the eaves front plate 15, and this eaves front plate 15 is
It is fixed to the lower end of the rafter 26. On the upper part of the rafter 26, a roof 30 is constructed via a field board 28. The attachment 12 is preferably made of resin, like the eaves gutter 10,
More preferably, it is made of the same composition as the eaves gutter 10.

A method of attaching the eaves gutter 10 to the attachment 12 is as follows. A projection 32 formed on the upper end of the attachment 12 is hooked on a concave portion 34 formed on the eaves gutter 10.
The claw 40 formed on the eaves gutter 10 is engaged with the claw 38 formed on the lower end of the second eaves. Thereby, the eaves gutter 10 is attached to the fixture 1.
2 attached. By the way, in the mounting fixture 12,
A parting edge 42 is integrally formed. This parting edge 42
Is a parting edge for the eaves 44 provided horizontally, and is formed so as to protrude from the lower part of the fixture 12 toward the eaves 44 side. Further, the parting edge 42 is formed in a hollow shape to reduce the weight. Further, a vertical surface 42A and a tapered surface 42B are formed on the right side surface of the parting edge 42 in the drawing. When the attachment 12 is attached to the fascia, the tapered surface 42B is positioned below the end 44A of the eaves 44. As a result, even if the parting edge 42 is looked up from just below the parting edge 42 in the direction of the arrow in the drawing, the end 44A of the eaves sky 44 is hidden by the projection 42C of the parting edge 42 and cannot be seen. Therefore, even if the parting edge 42 is not fixed to the eaves 44, the parting edge 42 can sufficiently function as a parting edge.

According to the eaves gutter structure constructed as described above,
Since the parting edge 42 of the eave roof 44 is integrally formed with the fixture 12, the number of parts is reduced as compared with the conventional eave gutter structure in which the eave sky is separate from the eave gutter and the fixture. FIG. 2 shows that the eave gutter structure shown in FIG. 1 is applied to a four-dimensional slope eave sky 46 parallel to the roof 30. As shown in FIG.
Is attached to the nose cover 14, the tapered surface 42B of the parting edge 42 is located below the end 46A of the eaves 46. As a result, even when looking up at the parting edge 42, the end 46A of the eaves sky 46 is hidden by the convex part 42C of the parting edge 42 and cannot be seen. Therefore, even when the parting edge 42 is applied to the eaves 46 having a four-dimensional slope, the function as the parting edge can be sufficiently exhibited.

The eaves 48 shown by the two-dot chain line in FIG.
It is a six-dimensional gradient eave parallel to the roof 31 shown by a two-dot chain line in FIG. In the same way, the mounting tool 12 can be used to hide the nose 1
4, the tapered surface 42B of the parting edge 42 is located below the end 48A of the eaves 48, so that the end 48A of the eaves 48 is hidden by the protrusion 42C of the parting edge 42 and cannot be seen. . Therefore, even if this parting edge 42 is applied to the eaves 48 having a six-dimensional slope, the function as the parting edge can be sufficiently exhibited.

In a conventional eave gutter structure in which a parting edge is fixed to the eaves, it is necessary to arrange a parting edge having a different shape for each eave with a different slope. In contrast, in the present embodiment,
The end of the eaves is hidden by the tapered surface 44B formed on the eaves 44 without fixing the parting edge to the eaves sky. it can. Therefore, in the present embodiment, the parting edge 44 can be shared, and thus, the fixture 12 can be shared.
