Abstract

PURPOSE:To surely prevent water leakage by making a pair of eaves gutters abut at their ends to each other, and fitting a gutter joint over this abutting portion, and also sticking to the outer face of each eaves gutter an elastic material provided on the inner face of the gutter joint. CONSTITUTION:A material comprising a metallic plate 1a coated at both sides with a synthetic resin 1b by extrusion molding is subjected to bending working so as to form a rectangular eaves gutter 1. A pair of eaves gutters 1 are made to abut at their respective ends to each other and a gutter joint 2 is fitted over the outer face of the abutting portion of the eaves gutters 1. The ear locking portion 4 of the gutter joint 2 is locked to the ear portion 3 of each eaves gutter 1 and an elastic material 5 provided on the inner face of the gutter joint 2 is stuck to the outer face of each eaves gutter 1. Thereby water leakage is surely prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a structure in which rectangular eaves gutters are connected by an eaves gutter joint.

[Prior Art] Conventionally, when connecting a pair of rectangular eaves gutters 1, the ends of the pair of rectangular eaves gutters 1 are abutted along the outer surface of this abutting portion. The gutter joint 2 is fitted over the eaves gutter 1, and the ear locking part 4 of the eaves gutter joint 4'2 is connected to the ear part 3 of the eaves gutter 1, and the outer surface of the eaves gutter 1 is connected as necessary. An adhesive is interposed between and the inner surface of the eaves/gutter joint 2 for bonding.

[Problem to be solved by the invention] However, in such a conventional example, the eaves gutter 1 is attached to the outer surface of the eaves gutter 1.
Even if the eaves gutter joint 2 is fitted, the eaves gutter joint 2 and the eaves gutter joint 2 are rectangular, so the outer surface of the eaves gutter 1 and the inner surface of the eaves gutter joint 2 will not meet as shown in There is a gap S between them.
J: There was a problem that it was difficult to connect the sea urchins to each other even if adhesive was used.

The present invention has been made in view of the above-mentioned points, and the purpose of the present invention is to prevent water leakage by being able to connect even rectangular eaves gutters in close contact without leaving any gaps. It is possible to provide a connection structure for eaves gutters.

[Means for Solving the Problems] In order to achieve the above object, the connection structure of the eaves gutter of the present invention is such that the ends of a pair of rectangular eaves gutter 1 are pushed against each other, and
A rectangular eave fiber sill 2 is fitted along the outer surface of the eaves gutter 1, and the lug stop 4 of the eaves gutter joint 2 is fitted onto the lug 3 of the eaves gutter 1.
The flexible elastic material 5 is tightly attached to the outer surface of the eaves gutter 1 on the inner surface of the eaves gutter joint 2.

[Function] When the eaves gutter joint 2 is fitted and the paired eaves gutter 1 are connected, the elastic material 5 comes into elastic contact with the outer surface of the eaves gutter 1 and comes into close contact with it, so that there is no gap between the eaves and gutter 1 as in the conventional case, and water leaks. It prevents leakage, and when an adhesive is used in combination, the adhesiveness improves, ensuring a secure connection and reliably preventing water leakage.

Example] The eaves gutter 1 is rectangular and is formed by bending a material in which both sides of a metal plate 1a such as a thin stainless steel plate are coated with a synthetic resin 11 such as vinyl chloride by extrusion molding. . At the upper end of the front part of the eaves gutter 1, there is a front ear part 3 as an ear part 3.
a, and the rear upper end of the eaves gutter 1 has a rear ear part 31) as an ear part 3.The upper part of the front wall of the eaves gutter 1 has a protruding part 6 that protrudes forward. , has a draining part 7 at the r end of the protruding part 6.The front ear part 3 = t is inclined so as to descend inward through the bent part 8, and is locked on the inner surface side of the bent part 8. A recess 9 is provided (J. The eaves gutter joint 2 is connected to the eaves gutter 1
It is formed of a plastic resin such as vinyl chloride into a rectangular shape along the outer surface of the eaves gutter joint 2, and a double-eared locking part 4a is provided as a 1f locking part 4 at the upper end of the front part of the eaves gutter joint 2. At the upper end of the rear part of the handle 2, a rear ear stopper 4b is provided as an ear stopper 4. The inner surface of the eaves gutter joint 2 except for the both ear locking portions 45I and the rear ear locking portions 41) is covered with a flexible elastic material 5 over the entire surface.
This is provided. The elastic material 5 may be a foamed resin such as vinyl chloride, and is preferably a material that is well impregnated with adhesive and whose surface is soluble. The eaves gutter 1 is connected in the following manner. −・
The ends of the pair of eaves gutters 1 are butted 6, and adhesive is applied to the outer surface of the butted portion of the eaves gutters 1 or the inner surface of the elastic material 5 of the eaves gutter joint 2. The eaves gutter joint 2 is fitted on the outer surface of the free-standing part, and the rear ear locking part 41 of the eave gutter joint 2 is:
) is locked to the rear ear part 3b so as to cover the rear ear part 41], and both ear parts 4a of the eaves gutter joint 2 are secured to the bent part 8. At this time, the elastic material 5 comes into close contact with the outer surface of the eaves gutter 1 so that no gap is formed, and the elastic material 5 ensures the adhesion of the adhesive, so that the connection can be ensured to prevent water from leaking.

Further, FIG. 4 shows another embodiment. In this embodiment, when connecting with the eaves/gutter joint 2, the inner retainer 10 is also used. This inner retainer 10 is formed in a shape that follows the inner surface of the eaves gutter 1, and has support rods 12 installed at the front and rear. A front hook portion 11a is provided at the front end of the inner presser 10, and a rear hook portion 11a is provided at the upper end of the rear portion of the inner presser 10.
b is provided. This inner retainer 10 is fitted onto the inner periphery of the abutting part of the eaves gutter 1, so that the front hook part 11a is locked in the locking recess 9, and the rear sliding part]]1] is the rear ear part. 3b and the rear ear locking portion 4b. By attaching the inner retainer 10 in this way, the eaves gutter 1 can be pressed from the inner side and the connection can be made more securely.

[Effects of the Invention] As described above, the present invention uses a flexible elastic material (provided on the inner surface of the eaves gutter joint) in close contact with the outer surface of the eaves gutter, so that it is possible to connect a rectangular eaves gutter to a rectangular eaves gutter joint. Even if the connection is made with an elastic material, there will be no gap between the outer surface of the eaves gutter and the inner surface of the eaves gutter joint, and the adhesion is particularly good when used with adhesive. , which can reliably prevent water leakage.
