Abstract

PURPOSE:To give strength so as to prevent the deformation due to elapsed time by forming the lower half of an eaves trough into a double wall, and by bending a side wall on the exterior side in the direction of a building, in such a way that the width of the opening between the upper half on the exterior side and the building side satisfies a certain size. CONSTITUTION:A bottom plate A provided with four strings of slit cavities 3a, 3b, 3c, 3d, an exterior side wall B which is provided with a hollow lug edge 6 on the point of the upper half B2 and which is bent in the side of a building at a stage 4, a side wall C on the building side provided with a hollow lug edge 7 on the upper end as well as a hollow expanded piece D protruded on the lower end, are provided so as to form an eaves trough. In consideration of a roof grading and rainfall intensity, the upper half B2 of the side wall B on the exterior side, is bent in the direction of the building in such a way that W0<W1, and W0=120mm are satisfied where W0 is the width of an opening and W1 is a maximum width of the eaves trough. On the other hand, b0>b1, and b0<b1+15mm are satisfied where b0 is the width of the hollow expanded piece D and b1 is the width of the lug edge 7 on the building side, so as to give strength. The deformation due to elapsed time is thus prevented, and good appearance can be retained.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides synthetic resin eaves gutters, particularly those that have excellent workability, prevent deformation over time, and maintain aesthetic appearance over a long period of time. This relates to eaves gutters made of synthetic resin.

[Conventional technology]

Conventionally, eaves gutters made of synthetic resin, such as eaves gutters made of polyvinyl chloride, have generally been used which have a semicircular cross section or a U-shaped cross section with reinforced edges at the upper ends of both sides.

This type of synthetic resin eaves gutter is more susceptible to thermal deformation and has lower strength than metal eaves gutter such as aluminum eave gutter or steel eave gutter, so it deforms over time such as meandering and widening after construction. Because it is easy to cause
A semicircular gutter with a double wall as seen in Publication No. 59 and Publication No. 10880 of Utility Model Publication No. 1988, etc.
A rectangular gutter with a double-bottomed bottom plate, as seen in Japanese Patent No. 85517, has been proposed.

[Problem to be solved by the invention]

However, since the synthetic resin eaves gutters mentioned above are simply double-walled walls such as semicircular gutters, when connecting vertical gutters using drains, the top surface of the bottom plate is curved like in semicircular gutters. With square gutter, the construction becomes very complicated because the alligator part cannot be rotated.On the other hand, with square gutter, a central partition piece is formed at the center in the width direction of the eaves gutter, and other Since the partition pieces are formed appropriately, not only the center partition piece gets in the way when drilling the insertion hole with a hole saw, making the drilling work complicated, but also the tightening work with the alligator part is difficult. When a hidden board is installed on the eaves, the edges of the eaves gutter on the building side and the fixed part of the mounting bracket are exposed from between the eaves and the eaves gutter, which impairs the aesthetics of the building and eaves gutter. sex was significantly reduced.

[Means to solve the problem]

At the outdoor end of the bottom plate, which has a plurality of slit-shaped cavities arranged side by side, the upper half is bent toward the building side, and a hollow locking piece is suspended from the tip. An outdoor side wall having a rim with a wide opening at the bottom is erected, and a building side wall having a hollow rim at the upper end is erected at the building side end of the bottom plate, and the building This eaves gutter is made of synthetic resin and has a hollow protruding piece extending in the longitudinal direction from the lower end of the side wall on the building side.

In addition, the above-mentioned partition pieces in the present invention include a central partition piece that runs along the longitudinal direction at a position slightly shifted from the center in the width direction of the bottom plate, and side partition pieces that run parallel to both sides at equal intervals with respect to the central partition piece. It is composed of three pieces,
In addition, the lower half of the side wall of the building is composed of a double wall with a partition piece formed so as to be continuous with the bottom plate, and
Figure 1 on the building side is a perspective view showing one embodiment of the synthetic resin eaves gutter of the present invention, Figure 2 is a sectional view of the same, and Figures 3 and 4 are sectional views showing the same in use. , A has slit-shaped cavities 3a, 3b, 3c, in which upper and lower bottom plates 2a, 2b made of horizontal plates are arranged side by side at equal intervals through three partition pieces 1a, lb, lc along the longitudinal direction. A bottom plate having four strips of 3d, the three strips of partition piece 1alb,
lc satisfies the width of the central partition piece 1a along the longitudinal direction at a position slightly shifted from the center in the width direction of the bottom plate A, and the width on both sides with equal intervals to the central partition piece 1a, bl: width of the building side edge) It has a trapezoidal cross section or a triangular cross section, and the width of the opening between the outdoor side ear edge and the building side ear edge is WO < -1 and MO = 120-s.
The upper half of the building side wall is curved toward the building so as to satisfy (WO: width of opening, -1: maximum width of eaves gutter).

Hereinafter, embodiments of the synthetic resin eaves gutter of the present invention will be described in detail with reference to the drawings.

〔Example〕

The outdoor side wall is erected at the end, and the lower half B1 is composed of a double wall having a partition piece 1d formed to be continuous with the bottom plate A, and the upper half B2 is a stepped part. 4 is bent toward the building side, and a hollow locking piece 5 is suspended from the tip of the ear edge 6, which has a wide opening on the lower side. , C is the above bottom plate A
This is a building-side side wall erected at the building-side end of the building, and is provided with a hollow edge 7 at its upper end. It is a hollow bulging piece that protrudes along the direction, and as shown in FIG. 2, b0>b1 and b0<b1+15mm (bo:
It is formed into a trapezoidal cross-section with a size that satisfies the width of the hollow bulge (bl: width of the building side edge).

Note that the upper half B2 of the outdoor side wall B is curved, and the roof extension dimension is the maximum of 1051 Japanese tiles. The lower half of the outer side wall is formed by a double wall connected to the bottom wall, while the building side wall is integrally formed with a hollow bulging piece provided at the lower end of the building side. This prevents deformations that occur over time, such as meandering and expansion, which are seen in conventional products.Furthermore, as shown in Figure 3, b0>b1 and b0<b1+15mm (bo: hollow expansion) Considering the trajectory of the above-mentioned hollow protruding piece made with the width of the projecting piece (bl: width of the building side ear edge) and the building side ear edge when it comes into contact with the fascia plate after installation, a minimum of 401 is required. Since the width of the hollow bulging piece is required to be 25Ill11, the width of the opening between the outdoor side edge 6 and the building side edge 7 is -0〈-
1 and 10 = 120 rigid m (WO: width of opening, circle 1
:The maximum width of the eaves gutter) is curved toward the building side.

〔Effect of the invention〕

As is clear from the above, the synthetic resin eaves gutter of the present invention is
The bottom plates are arranged horizontally with partition pieces in between, and the center partition piece of the bottom plate is formed along the longitudinal direction at a position slightly offset from the center part in the width direction of the bottom plate, and side partitions are formed. Since the pieces are formed parallel to the central partition piece near both sides at equal intervals, the drilling work with a hole saw when installing the drain is simplified, and the drain can be firmly tightened by the collar. In addition, since the hollow bulging piece is formed to have a trapezoidal cross section or a triangular cross section, the hollow bulging piece does not get in the way when connecting with a joint, so the connecting work can be easily performed. Furthermore, the width of the opening between the outdoor side ear edge and the building side ear edge is -0 -1 and 10 = 1.
20t+* (WO: Width of the opening, W is the maximum width of the eaves gutter)
By curving the upper half of the outdoor side wall toward the building to satisfy 1 - One partition piece 3 - One hollow part 5 - One locking piece 7 - One hollow edge edge - Upper and lower bottom plate step part Since the projecting dimensions of the edge fitting can be handled with one type, the workability is also improved. be.
