Abstract

PROBLEM TO BE SOLVED: To prevent water leakage from between the bottom of the fitted part of eaves gutters and the bottom of the eaves gutter by providing a cut-off member at the inner peripheral face of the fitted part of eaves gutters of both ends and providing a pressing member to press the bottom of the eaves gutter at the part where the cut-off member is arranged. SOLUTION: The joint body 1 of a bend joint A made of synthetic resin is formed to have a nearly L-shaped section and fitting parts 2, 2 to which eaves gutters can be fitted are provided at both ends thereof. Belt-form cut-off members 3 made of synthetic rubber are buried in the inner peripheral face of the fitting part 2 of the eaves gutter. The protruded part from the surface of the fitting part 2 is formed to have a ragged surface. A nearly lateral L- shaped pressing member 4 is fitted so as to cover the cut-off member 3 to hold the end of the eaves gutter by the pressing member 4 and the cut-off member 3. Accordingly, even when the eaves gutter is extended or contracted breadthwise in accordance with a change of air temperature, the eaves gutter is prevented by the pressing member 4 from swelling and any gap is not brought between the bottom of the fitting part of the eaves gutter and the bottom of the eaves gutter. Accordingly, water leakage out of the gap can be prevented.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved joint provided at the eaves of a house.

[0002]

2. Description of the Related Art Conventionally, as a curved joint for connecting eaves gutters at the eaves, there is, for example, one described in Japanese Patent Application Laid-Open No. 9-41592. This bent joint is approximately L
In a bent joint formed at both ends with an eaves gutter fitting portion capable of fitting an eaves gutter, a water-stopping material is formed on the inner peripheral surface of the eaves gutter fitting portion, and the shape is substantially L-shaped. At the upper end of both ends of the side wall of the eaves gutter, a holding member for holding both ears of the eaves gutter and a shielding member for covering the upper side of the holding member are provided. This bent joint presses both ears of the eaves gutter fitted to the eaves gutter fitting portion of the bent joint with holding members at the upper ends of both ends of the side wall,
It stops the both ends of the eaves gutter, prevents water leakage from the side wall and bottom with the waterproof material provided on the inner peripheral surface of the eaves gutter fitting part, and connects the eaves gutter and the bent joint, It has a simple structure and is easy to use.

[0003]

However, the eaves gutter may expand and contract in the length and width directions of the eaves gutter as the temperature changes. In the bent joint described in Japanese Patent Application Laid-Open No. 9-41592, the elongation and contraction in the longitudinal direction can be absorbed by the eaves gutter sliding on the waterproof material at the eaves gutter fitting portion. The expansion and contraction in the width direction is a pressing member at the upper end of both ends of the side wall of the eaves gutter fitting portion of the bent joint, and both ears of the eaves gutter are pressed from above,
The widthwise movement is stopped by the water-stopping material and the side wall of the fitting part of the eaves gutter of the curved joint, so the repulsion force by the water-stopping material and the force from the orthogonal direction due to the corners are applied, and the eaves gutter The bottom of the bent joint rises, a gap is formed between the bottom of the eave gutter fitting portion of the bent joint and the bottom of the eave gutter, and there is a problem that water leaks from this gap. Therefore, an object of the present invention is to
In view of the above problems, it is an object of the present invention to provide a bent joint in which the bottom of the eaves gutter does not rise even when the temperature changes.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and has an eave gutter fitting portion formed at both ends thereof, which is formed in a substantially L-shape, and into which an eave gutter can be fitted. In the bent joint, a water stopping material is provided on the inner peripheral surface of the eave gutter fitting portion at both ends of the eave gutter fitting portion.
A holding member for holding the bottom of the eaves gutter is provided.

[0005] In the present invention, the material and shape of the water-stopping material on the inner peripheral surface of the eaves gutter fitting portion may be provided on the inner peripheral surface of the eaves gutter fitting portion of the curved joint so as to prevent water leakage. For example, a suitable material and shape may be used.For example, a band-shaped rubber is embedded in the inner peripheral surface of the eaves gutter fitting portion of the bent joint, and the surface of the water-stopping material protrudes from the surface of the eaves gutter fitting portion. When the eaves gutter is fitted into the eaves gutter fitting portion, water leakage can be prevented by the bottom surface of the end of the eaves gutter and the water-stopping material, which is preferable.

In the present invention, the material and shape of the holding member for holding the bottom of the eaves gutter may be any appropriate material and shape as long as the bottom of the eaves gutter can be held down to prevent the bottom from rising. The material is made of vinyl chloride resin of the same material as the eaves gutter. The shape of the holding member is substantially L-shaped, and the lower end of the approximately L-shaped vertical member is bent to the bottom of the eaves gutter fitting portion of the joint. Attach the waterproof material to the bottom of the fitting part of the eaves gutter of the bent joint, and clamp the end of the eave gutter between the substantially horizontal L-shaped cross member and the waterproof material attached to the bottom. This is preferable because the structure is simple and the bottom of the eaves gutter can be pressed down by the holding member to prevent the bottom of the eaves gutter from rising.

Although the holding member is attached to the bottom of the eave gutter fitting portion of the bent joint, it is preferable from the viewpoint of aesthetics if the eave gutter fitting portion of the bent joint and the holding member are integrally formed by injection molding. .

(Effect) As the temperature changes, the eaves gutters and bent joints (extends and contractions of the bent joints are very small) expand and contract in the length and width directions of the eaves gutter. When the eaves gutter expands and contracts in the width direction due to the difference in expansion and contraction between the eaves gutter and the bend joint, the end of the eaves gutter is fitted into the eaves gutter fitting portion of the bend joint, and the eaves gutter is located at the corner. Can not absorb the expansion and contraction in the width direction of the eaves gutter, and the eaves gutter is deformed by the repulsive force of the waterproof material and the force from the orthogonal direction due to the corners, etc. May swell. In the bent joint of the present invention, a waterproof material is provided on the inner peripheral surface of the eaves gutter fitting portion at both ends of the bent joint,
Since the holding member that presses the bottom of the eaves gutter is provided in the portion where the water stopping material is arranged, the eaves gutter expands and contracts in the width direction with the change in temperature as described above, and the water stopping material is used. Even if repulsive force or force from the orthogonal direction due to being in the corner is applied, hold the end of the eaves gutter between the water stop material and the holding member on the inner peripheral surface of the eaves gutter fitting part. , The holding member can hold down the swelling force at the bottom of the eaves gutter, and the eaves gutter does not deform,
The bottom of the eaves gutter does not rise, and no gap is formed between the bottom of the eaves gutter fitting portion of the bent joint and the bottom of the eaves gutter.
