Abstract

PROBLEM TO BE SOLVED: To prevent the breakage or destruction of a joint main body due to the thermal expansion and shrinkage of eaves gutters by providing a reinforcing rib on the inside of the upper section of a side wall located on the indoor side except for the eaves gutter connection sections of the joint main body in an eaves gutter curved joint provided with the eaves gutter connection sections at both end sections of the joint main body bent into a nearly L-shape. SOLUTION: An eaves gutter curved joint A injection-molded with a vinyl chloride resin is formed with a gutter-like joint main body 1 bent into a nearly L-shape on the plan view and eaves gutter connection sections 2, 2 provided at both end sections of the joint main body 1, and gutter lug hook sections 21, 22 having a U-shaped cross section are provided at the upper ends of both side walls of the eaves gutter connection sections 2, 2. A hollow, square tubular reinforcing rib 3 is integrally provided over the whole length on the inside of the upper section of a side wall 11 located on the indoor side (on the fascia board side when fitted to the eaves edge) of the joint main body 1 except for the eaves gutter connection sections 2, 2. The eaves gutter curved joint A is hardly brought into contact with the fascia board corner, the strength of the eaves gutter curved joint A itself is increased by the reinforcing rib 3, and no crack is generated on the joint main body 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION As a conventional eaves gutter joint, there is known a joint described in JP-A-8-277612. The conventional eaves gutter bent joint is provided with a notch in the upper part of the bent crossing side wall on the corner side of the joint body, and the notch corresponds to expansion and contraction due to the temperature of the eaves gutter connected thereto, and the notch extends in the width direction. They become longer or shorter and try to absorb power.

[0002]

However, in the case of the above-mentioned conventional eaves gutter bending joint, when the eaves gutter shrinks, the bend cross wall portion is pulled toward the nose cover plate, and at this time, the outside of the bend cross portion is pulled out. When the reinforcing ribs are provided, the bent intersection wall portion is more likely to come into contact with the corner of the fascia, resulting in breakage of the bent intersection portion.

[0003] An object of the present invention is to provide an eaves gutter bent joint that can prevent breakage or destruction of the joint body due to thermal expansion and contraction of the eaves gutter.

[0004]

According to a first aspect of the present invention, there is provided an eaves gutter bent joint in which eaves gutter connection portions are provided at both ends of a joint body bent and formed substantially in an L shape. Reinforcing ribs are provided inside the upper part of the side wall located on the indoor side excluding the eaves gutter connection part of the main body.

(Function) In the present invention according to the first aspect, since the reinforcing ribs are provided inside the upper part of the side wall located on the indoor side of the joint body except for the eaves gutter connecting portion, the corner of the nose cover plate is provided. Are increased and the contact becomes difficult, and the presence of the reinforcing ribs increases the strength of the joint body itself.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a gutter bend joint according to the present invention, and FIG. 2 is an explanatory view showing a use state of the gutter bend joint of FIG.

In FIG. 1, reference numeral A denotes an eaves bend joint used at a protruding corner of a building, which is formed by injection molding a vinyl chloride resin. The eaves gutter joint A is composed of a gutter-shaped joint body 1 bent and formed in a substantially L-shape in plan view, and eaves gutter connection portions 2 and 2 provided at both ends of the joint body 1. . At the upper ends of both side walls of the eave gutter connection portions 2, 2, gutter ear locking portions 21, 22 having a U-shaped cross section are provided.

Reinforcing ribs 3 are integrally formed on the inner side of the upper portion of the side wall 11 located on the indoor side of the joint body 1 (when attached to the eaves, on the side of the nose shield 4) except for the eaves gutter connection portions 2 and 2. It is provided in. The reinforcing rib 3 is a rectangular hollow member. As is clear from the figure, the outer surface of the upper end of the side wall 11 of the joint body 1 is located more outdoor than the outermost surface of the gutter ear engaging portion 22.

Next, the use of the eaves gutter joint A will be described with reference to FIG. First, an eaves gutter is attached to a protruding eaves corner of a building using an eaves gutter bending joint A in the same manner as in the prior art. That is, a hanging tool (not shown) is fixed to the front surface of the nose cover 4 at a predetermined interval with a nail or the like.
The eaves gutters 5 and 5 are arranged while holding the gutter ears with these hanging tools.
Next, an adhesive is applied to the inner surfaces of the both eave gutter connection portions 2 and 2 of the eave gutter bent joint A in a string shape, and the both eave gutter connection portions 2 and 2 are fitted to the outer surfaces of the ends of the both eave gutters 5 and 5. By bonding and fixing, the installation work of the eaves gutter 5 in front of the fascia plate 4 is completed.

As the temperature rises, the eaves gutters 5, 5 connected to the eaves gutter joint A extend, and the elongation force of the eaves gutters 5, 5 is transmitted from the eaves gutter connection portions 2, 2 of the joint body 1. , And joins the eaves gutter joint A in a direction of pulling it away from the nose shield plate 4. In this case, it is sufficient to absorb the force due to the elasticity of the eaves bent joint A, but in the above embodiment, the reinforcing rib 3 is present inside the upper part of the side wall 11 located on the side of the nose cover 4 of the joint body 1. Therefore, it is possible to firmly cope with an external force caused by the extension force of the eaves gutters 5, 5.

On the other hand, when the temperature drops, the eaves gutters 5, 5 connected to the eaves gutter joint A contract, and the eaves gutters 5, 5 are contracted.
The contraction force 5 is applied from both the eaves gutter connection portions 2 and 2 of the joint body 1 in a direction in which the eaves bend joint A approaches the fascia plate 4.
In this case, in the above embodiment, since the reinforcing ribs 3 are present over the entire length inside the upper part of the side wall 11 located on the side of the nostril plate 4 of the joint main body 1, the contraction force of the two eaves gutters 5, 5 is provided. Can firmly cope with external forces caused by

In the above embodiment, as the eaves gutter bending joint,
Although the one used at the eaves corner of the eaves is illustrated, it is a matter of course that the above technical idea can be applied to the eaves gutter joint used at the eaves corner of the eaves.

In the above embodiment, the hollow rib-shaped reinforcing rib is provided integrally with the hollow rib-shaped reinforcing rib on the inner surface of the side wall 11, but a separately formed hollow rib of the same shape is bonded to the inner surface of the side wall. It may be adhered and fixed with an agent.

[0013]

According to the first aspect of the present invention, since the reinforcing rib is provided on the upper side inside the side wall located on the indoor side of the joint main body, the interval between the corner of the nose shield and the corner is widened, so that it is difficult to make contact. At the same time, the reinforcing ribs increase the strength of the eaves bent joint itself, and are advantageous without causing cracks in the joint body or breaking the joint body.
