Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an eaves gutter attached to the eaves of a house and a connection structure for the eaves gutter.

(Conventional technology) Conventionally, there are two types of eaves gutters: synthetic resin eaves gutters and metal eaves gutters. In any case, when connecting eaves gutters,
It was connected via a gutter joint.

(Problems to be Solved by the Invention) However, synthetic resin eaves gutters undergo thermal expansion and contraction as the temperature changes, so there is a risk of deformation due to the thermal expansion and contraction. In addition, it lacks durability due to deterioration over time, and lacks rigidity, making it unsuitable for use in areas with heavy snowfall. On the other hand, when it comes to metal eaves gutters. Although high rigidity can be ensured by increasing the wall thickness, there are problems such as making processing difficult and increasing material costs.

The present invention has focused on the above-mentioned conventional problems, and has developed an eave gutter and eave gutter connection structure that can prevent deformation due to thermal expansion and contraction and deterioration over time, has low material cost, is easy to process, and has high rigidity. is intended to provide.

(Means for Solving the Problems) In order to achieve the above object, the eaves gutter of the present invention has a thin metal eave gutter attached to the outside of the synthetic resin eaves gutter. Further, in the eaves gutter, it is preferable that the synthetic resin eaves gutter and the metal eaves gutter have the same length and are joined with their ends shifted by a predetermined width in the longitudinal direction.

Further, in order to achieve the above object, the eaves gutter connection structure of the present invention is such that the synthetic resin eaves gutter and the metal eaves gutter have the same length, and the end portions have a predetermined width in the longitudinal direction. In the connection structure of the eaves gutters that are joined in a shifted state, the end on the side where the synthetic resin eaves gutter overhangs is inserted inside the end on the side where the metal eaves gutter overhangs. , the ends of synthetic resin eaves gutters are butted together, and the ends of metal eaves gutters are butted and connected. (Function) In the eaves gutter of the present invention, since the shape of the synthetic resin eaves gutter is maintained by the metal eaves gutter, deformation of the synthetic resin eaves gutter due to thermal expansion and contraction can be prevented, and deterioration over time can be prevented. Additionally, since it has a double gutter structure of synthetic resin eaves gutters and metal eaves gutters, the overall rigidity is improved. Moreover, since metal eaves gutters are thin, the material cost is low and they are easy to process.

Furthermore, if a synthetic resin eaves gutter and a metal eaves gutter have the same length and are joined with their ends shifted by a predetermined width in the longitudinal direction, the eaves gutter must be connected to each other. To do this, insert the end of the side where the synthetic resin eaves gutter overhangs into the inside of the end of the side where the metal eaves gutter overhangs,
The ends of synthetic resin eaves gutters can be butted against each other, and the ends of metal eaves gutters can be butted and connected.

That is, the eaves gutters can be connected to each other without using a gutter joint, and the outer surface of the connecting portion of the eaves gutters can be made into a single surface without any level difference. Further, since the joints of the synthetic resin eaves guttering and the metal eaves troughs do not overlap but are shifted in the longitudinal direction, water leakage from the joints of the eaves troughs can be prevented.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of the embodiment will be explained based on FIGS. 1 to 4.

As shown in FIG. 1, the eaves gutter A of this embodiment has a single gutter structure in which a metal eaves gutter 2 is fitted onto the outside of a synthetic resin eaves gutter I. As shown in FIG. 4, the synthetic resin eaves gutter 1 and the metal eaves gutter 2 have the same length, and are joined with their ends shifted by a predetermined width in the longitudinal direction. ．． That is, the eaves gutter A has an end portion from which the synthetic resin eaves gutter 1 overhangs on one side, and an end portion from which the metal eaves gutter 2 overhangs on the other side. It is preferable that the synthetic resin eaves gutter 1 and the metal eaves gutter 2 be glued to each other so that their relative positions do not move, but this gluing work may be done in advance at the factory or on-site. It can also be done during construction.

As shown in FIG. 2, the synthetic resin eaves gutter 1 is an extrusion molded product, with a front wall 12 standing upright from the front side of the flat bottom wall 11, and a rear wall 13 extending from the rear side of the bottom wall 11. It is formed in a groove-shaped cross section with an upright structure. In addition, the front side wall l2 is formed to bulge outward slightly, and the rear side wall l3 is formed to be slightly bulged outward.
It is installed perpendicular to 1.

A front ear 14 is formed at the upper end of the front side wall l2, and the front ear 14 has a full length of 141 mm on its upper surface and inner surface.
142 is formed, and a locking piece 143 whose tip is folded back is formed on the bottom surface. In addition, the rear side wall l
A rear ear l5 is formed at the upper end of 3, and this rear ear l5
151 is formed on the inner surface, and a locking piece 152 whose tip is folded back forward is formed on the bottom surface.

Note that the grooves 141 and 142 of the front lug 14 and the grooves 151 of the rear lug 15 serve as mounting grooves for attaching the eaves gutter A to a support (not shown).

The metal eaves gutter 2 is a thin-walled press-formed product as shown in FIG.
2 is erected, and the rear side wall 23 is erected from the rear measuring portion of the bottom wall 2l, forming a groove-shaped cross section. The metal eaves gutter 2 is formed so that the inner surface shape almost matches the outer surface shape of the synthetic resin eaves Iil1l, and the front side wall 2
A front ear 24 is formed at the upper end of 2, and a rear ear 25 is formed at the -hi end of the rear side wall 23. That is, this metal eaves gutter 2 has the front lug 24 fitted into the locking piece 143 of the front l4 of the synthetic resin eaves gutter i, and the rear lug 25 of the eave gutter l made of synthetic resin. By fitting into the engagement piece 152, it is attached to the outside of the synthetic resin eaves gutter I.

Next, the operation of the embodiment will be explained.

In the eaves gutter A of this embodiment, the synthetic resin eaves gutter 1 is replaced by the metal eaves gutter 2.
Since the shape is maintained by the synthetic resin eaves gutter l, deformation due to thermal expansion and contraction can be prevented, and deterioration over time can be prevented.

Moreover, since the eaves gutter A of this embodiment has a double gutter structure of the synthetic resin eave gutter 1 and the metal eave gutter 2, the overall rigidity is improved. Moreover, since the metal eaves gutter 2 is thin, the material cost is low and processing is easy. Further, the surface color of the metal eaves gutter 2 may be the same as the ground color, or may be painted. These increase the variation in the surface color of the eaves gutter A.

Furthermore, the operation of connecting the eaves gutters A to each other in the longitudinal direction will be explained with reference to FIG.

When connecting the eaves gutter A, insert the end of the side where the synthetic resin eaves gutter l overhangs into the inside of the end of the side where the metal eaves gutter 2 overhangs, and connect the synthetic resin eaves gutter l. The ends of the metal eaves gutters 2 are butted against each other, and the ends of the metal eaves gutters 2 are butted against each other to connect.

Then, the eaves gutter A can be connected without using a gutter joint, and the outer surface of the connecting portion of the eaves gutter A can be made into a single surface with no level difference. Further, although the joints of the metal eaves gutter 2 are visible on the outside, the metal eaves gutter 2 is thin, so the joints can be made inconspicuous. Furthermore, since the joints of the synthetic resin eaves gutter 1 and the metal eaves gutter 2 do not overlap but are shifted in the longitudinal direction, water leakage from the joints of the eaves gutter A can be prevented by applying adhesive or the like.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and even if there are design changes within the scope of the gist of the present invention, they are included in the present invention.
