Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter fixture for attaching a downspout or eaves gutter to a building, and more particularly to a decorative structure of a building in which PVC steel sheets (steel sheets on which soft polyvinyl chloride is laminated) are laminated. The present invention relates to a gutter fixture attached to a plate.

[0002]

2. Description of the Related Art Synthetic resin fittings have begun to replace metal gutter fittings. As this synthetic resin,
Polycarbonate is used from the viewpoints of weather resistance and little change over time. In addition, as a decorative panel for an outer wall of a building, a panel in which a PVC steel sheet (a steel sheet having soft polyvinyl chloride laminated on the surface) is laminated on the outer surface is often used. Therefore, the synthetic resin fixture is directly attached to the PVC steel plate with nails or screws.

[0003]

However, in such mounting, the fixing plate of the gutter fixture is brought into close contact with the PVC steel plate under the pressure of nails or the like, but is contained in the polyvinyl chloride of the PVC steel plate. There has been a problem that the plasticizer appears on the surface of the PVC steel plate due to a change with time, and erodes the fixing plate of the fixture, causing cracks.

[0004] In order to solve this problem, a method of not including a plasticizer in polyvinyl chloride of a PVC steel sheet can be considered.
The plasticizer is for softening polyvinyl chloride when laminated on the surface of the steel sheet, and is indispensable.
Not a satisfactory solution. In addition, it is advisable to find a means for suppressing the erosion of the plasticizer in consideration of installation in a building already constructed.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a gutter fitting which is made of polycarbonate as a main material and which does not cause a crack even if a plasticizer seeps out of a PVC steel plate due to a change over time. is there.

[0006]

Means for Solving the Problems As a result of intensive studies in view of the above, the present inventor has provided a substantially plate-shaped fixing plate at the base end, and extends from a plane of the fixing plate in a substantially orthogonal direction. A gutter support having a holding member for holding the gutter, wherein a gutter fixture having at least a contact surface of the fixing plate made of polycarbonate is provided with a spacer on the contact surface, and a critical stress value (50 ° C, 24 hours)
It has been found that the above problem can be solved by setting the pressure to 200 kgf / cm ^2, and the present invention has been completed.

Here, the spacer according to the present invention must be made of a material that does not allow the plasticizer from the PVC steel plate to contact the contact surface and that the spacer itself is not eroded by the plasticizer. Stress value (50 ° C,
24 hours) should be 130 to 2200 kgf / cm ² . For example, stainless steel, aluminum,
Metals such as iron, steel, copper, zinc, nickel or other simple or alloys, and synthetic resins that are not easily affected by plasticizers even with thermoplastic resins or thermosetting resins (for example, hard polyvinyl chloride, polyethylene, polyester, There is a synthetic resin such as a simple substance or a composite of polystyrene, acrylonitrile, butadiene, and styrene. The above materials may be used not only alone but also in a composite form. In the case of a synthetic resin, reinforcing fibers (eg, glass fibers, aramid fibers, metal fibers, etc.) may be embedded. The thickness of the spacer can be appropriately changed depending on the plasticizer resistance of the material to be adopted, and the shape itself can appropriately correspond to the shape of the fixing plate of the gutter fixture. Further, the spacer and the fixing plate are provided with fitting portions that fit each other, so that the spacer can be integrated with the gutter fitting.

[0008] The critical stress value is a critical value at which the stress and strain values when a material is continuously strained maintain a proportional relationship. The term “50 ° C., 24 hours” refers to the temperature and the immersion time when the test piece fixed with the metal fitting was immersed in the plasticizer so as to follow the quarter elliptic curve. It is a value calculated by using the distance X to the crack or craze occurrence limit point generated on the piece, and specifically, is a value calculated by the following formula: “Test at a position of distance Xcm in the X coordinate axis direction from the center of the ellipse Piece strain;
(t is the thickness of the test piece)
(cm)).

Ε = 0.02 × (1-0.084X ² ) ^{-3t / 2} Critical stress (kgf / cm ² ) = ε × Flexural modulus of test piece (kgf / cm ² )

The plasticizer added to the polyvinyl chloride of the above-mentioned polyvinyl chloride steel sheet includes phthalate ester, aromatic carboxylate ester, aliphatic dibasic ester ester, epoxy resin and phosphate ester. System, aliphatic ester system, chlorine-containing system, polyester system and the like. In general, phthalate ester phthalate, octyl phthalate and the like are employed.

[0011] The material of the gutter fixture is intended for a polycarbonate fixing plate, and may not be entirely made of polycarbonate. The material other than polycarbonate can be appropriately selected as long as it has a rigidity capable of supporting the gutter for a long period of time.For example, metals such as stainless steel, aluminum, iron, steel, copper, zinc, nickel or the like alone or alloy, There is a synthetic resin such as a thermoplastic resin (for example, polyvinyl chloride, polyethylene, polyester, polystyrene, acrylonitrile / butadiene / styrene, polycarbonate) or a thermosetting resin alone or in a composite. In the case where the rigidity of the material itself is low, a rigid metal, a synthetic resin, or a reinforcing fiber (for example, a glass fiber, an aramid fiber, a metal fiber, etc.) may be embedded inside and outside the material to increase the rigidity. Of course, in order to improve the surface smoothness of the material, rubber or a synthetic resin having flexibility may be laminated. Also,
The shape may be a simple plate-like body, or a shape in which ribs are provided on both sides of the holding piece.

The gutter to be attached in the gutter fixture according to the present invention includes an eave gutter, a down gutter, an eave gutter joint, a gutter joint, and the like.
It is all rain gutters such as eaves gutters. Further, the gutter supporting portion can be appropriately selected according to the shape of the gutter which is the attached member.
