A resin eaves trough, which is a synthetic resin eaves trough in which a kerf 7 extending in the longitudinal direction is formed on a front plate on each hollow chamber.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a synthetic resin eaves gutter, in particular, a hollow having a plurality of hollow chambers formed with a front plate and a back plate in which at least the bottom plate of the eaves gutter body is juxtaposed through a partition wall extending in the longitudinal direction. The present invention relates to a synthetic resin eaves gutter made of a plate.

[0002]

[Prior Art]

 Conventionally, as a synthetic resin eaves trough of this type, as seen in Japanese Utility Model Laid-Open No. 63-128921, the wall and bottom plate of the eaves gutter body curved in a U-shaped cross section are made of a low-polymerization vinyl chloride resin. Generally, a synthetic resin with a high hardness such as is integrally formed by extrusion molding is used, but the wall and bottom plates are composed of a single plate made of synthetic resin with poor heat resistance. Because of this, it was forced to undergo thermal deformation such as meandering over time.

Therefore, in order to prevent the above thermal deformation, as seen in Japanese Utility Model Laid-Open No. 4-43625, at least the bottom plate of the eaves gutter body is arranged side by side through a partition wall extending in the longitudinal direction. A synthetic resin eaves gutter consisting of a hollow plate having a plurality of hollow chambers formed with a back plate has been used.

[0004]

[Problems to be solved by the device]

 However, the synthetic resin eaves troughs have rainwater flowing into the hollow part of the eaves gutter body from the connection part between the eaves gutters connected using joints and the end of the eaves gutter closed by a stop, and the hollow part There was a problem that the rainwater that stayed in the area freezes in winter and damages the eaves gutter body, causing water leakage.

The present invention was devised to eliminate the drawbacks of the conventional products described above, and is intended to provide a synthetic resin eaves trough which prevents water leakage due to damage to the eaves gutter body.

[0006]

[Means for Solving the Problems]

 The present invention has been devised in view of the above, and has a plurality of hollow chambers formed by a front plate and a back plate in which at least the bottom plate of the eaves gutter body is juxtaposed with a partition wall extending in the longitudinal direction. A synthetic resin eaves trough consisting of a hollow plate having a hollow plate, wherein the front plate on each hollow chamber is provided with a kerf along the longitudinal direction.

[0007]

[Action]

 The eaves trough made of synthetic resin according to the present invention is composed of a hollow plate having a plurality of hollow chambers formed by a front plate and a back plate in which at least the bottom plate of the eaves gutter body is juxtaposed with a partition wall extending in the longitudinal direction. It is a synthetic resin eaves gutter consisting of the following features: the front plate on each hollow chamber is provided with notches along the longitudinal direction, and rainwater that accumulates in the hollow portion freezes in the winter. The stress causes a crack in the kerf portion of the front plate, and since the stress is absorbed, the back plate used for waterproofing is not damaged.

[0008]

【Example】

 Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings. FIG. 1 is a perspective view showing an embodiment of a synthetic resin eaves gutter of the present invention, and FIG. 2 is a partially enlarged sectional view of the same. Is.

In the figure, A is an eaves gutter body formed by extrusion molding using a hard vinyl chloride resin as a material and having a U-shaped cross section, and a front-side lower wall portion 1 and a bottom plate 2 are partitioned along the longitudinal direction. It is a hollow plate having a plurality of hollow chambers 6 formed by a front plate 4 and a back plate 5 which are arranged side by side with a wall 3 therebetween. The surface of the front plate 5 is provided with kerfs 7 each having a V-shaped cross section along the longitudinal direction.

The front plate 4 is preferably formed to be thinner than the back plate 5 in order to favorably absorb the stress due to the crack in the cut groove 7 portion caused by the freezing of the rainwater.

[0011]

[Effect of the device]

 As is clear from the above, the synthetic resin eaves gutter of the present invention has a plurality of hollow eaves formed by a front plate and a back plate in which at least the bottom plate of the eaves gutter body is juxtaposed by a partition wall extending in the longitudinal direction. It is a synthetic resin eaves trough consisting of a hollow plate with a chamber, and because it has a structure in which a cut groove along the longitudinal direction is engraved on the surface plate on each hollow chamber, the inside of the hollow part from the joint part and the stop part Even if the rainwater that flows in and stays in the water freezes in winter, the stress causes cracks in the kerf of the front plate, and the stress is absorbed, causing damage to the back plate used for waterproofing. In this way, the conventional water leakage is eliminated.
