Abstract

PROBLEM TO BE SOLVED: To prevent any crack on a stationary plate being produced by a plasticizer containing in vinyl chloride sheet steel of an external wall panel by reducing a contact area with the external wall of a building by way of installing some irregularities on this stationary plate, in a gutter fixture made of polycarbonate. SOLUTION: A gutter fixture made up of polycarbonate on the whole holds an eaves gutter N by means of two holding members 4, thereby securing a stationary plate 1 to an external wall panel K of a building by hold-down members including a nail and a screw or the like. Polyvinyl chloride-coated sheet steel P is laminated on this panel K, and some irregularities are formed on a contact surface 2 with the stationary plate 1 in contact with a soft polyvinyl chloride layer of the outer surface. With this, a contact area between the stationary plate 1 and the polyvinyl chloride- coated sheet steel P is reduced, and thereby any effect of a plasticizer being produced out of polyvinyl chloride of the polyvinyl chloride-coated sheet steel P due to a secular change is reduced, and thus any crack is preventable from occurring in the stationary plate 1 made of polycarbonate. In addition, when a projecting part of the irregularities being formed on the contact surface 2 is sharpened in a sectional triangular form, the degree of stationariness in the stationary plate 1 is well improvable.

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 in that the plasticizer that has appeared on the surface of the PVC steel plate due to a change with time, erodes the fixing plate of the fixture, and causes 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.

Accordingly, an object of the present invention is to provide a gutter fixture made of polycarbonate which does not cause cracks even when a plasticizer appears from a PVC steel plate due to a change with time.

[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 at least a contact surface of the fixing plate is made of polycarbonate, and the contact surface is provided with irregularities, and a contact area with the PVC steel plate is reduced. The inventors have found that the above problem can be solved by reducing the number, and completed the present invention.

Here, the unevenness of the contact surface of the fixture of the gutter fixture according to the present invention can be appropriately selected as long as the contact area with the above-mentioned PVC steel plate can be reduced. And a projection in which only the outer frame of the contact surface protrudes. The shape of the projection includes a quadrangular shape, a triangular shape, a semicircular shape, a semi-elliptical shape, and the like in a longitudinal section.

The gutter fixture according to the present invention is intended not only for the case where the whole is made of polycarbonate but also for the case where at least the fixing plate is made of polycarbonate.
The gutters to be attached are all rain gutters such as eaves gutters, vertical gutters, eaves gutter joints, gutter gutters, and eave gutter collectors. Further, the gutter supporting portion can be appropriately selected according to the shape of the gutter which is the attached member.

The material of the gutter fixture may be any material other than polycarbonate as long as it has rigidity capable of supporting the gutter for a long period of time. For example, stainless steel, aluminum, iron, steel, copper, zinc And metal such as a simple substance or an alloy such as nickel, a thermoplastic resin (for example, polyvinyl chloride, polyethylene, polyester, polystyrene, acrylonitrile-butadiene-styrene, polycarbonate) and a synthetic resin such as a simple substance or a composite of a thermosetting resin. 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. Further, the shape may be a simple plate-like body or a shape in which ribs are provided on both sides of the holding piece.
