Description

  The present invention relates to a decorative sheet for a roof that is attached along the eaves of the roof or the keraba that is the end on the side of the roof, and decorates the periphery of the roof, and integrally connects the ends of the decorative panel without using a joint member. The present invention relates to a structure formed to be able to.

  In building around the eaves and gable roofs of houses, in order to improve the appearance and improve the appearance of the end of the eaves and the end of the wife, the resin-coated steel sheet coated with a vinyl chloride resin sheet is folded to make a decorative board. Form it and attach it along the eaves or keraba.

FIG. 8 shows an appearance of an example of a decorative board that decorates the appearance of the end portion on the roof side.
As shown in the figure, this decorative board 100 is constructed by inserting a side covering surface portion 101 covering the side of the roof side end portion, a lower covering surface portion 102 covering the lower side, and an end portion of the eaves ceiling into the roof side end portion. Each of the concave portions 103 is fixed to the lower surface of the lower covering surface portion 101, and the lower covering surface portion 102 is bent backward in a substantially L shape by a bent portion 104 provided at the lower end of the side covering surface portion 101. Concave portion 103 is formed in a cross-sectional shape with a bent portion 104 provided at the end and bent upward in a substantially L shape, and is attached to the eaves side from the ridge side along the keraba to break the roof side end portion. It is housed in the appearance as if a plate was attached (for example, see Patent Document 1).

JP2013-256811A

The decorative plate 100 is manufactured by bending a long flat plate made of a steel plate using a press mold such as a press brake, and both end portions (A end and B end in FIG. 8) of the decorative plate 100 are formed. It is formed in a contour shape of the same shape and size.
Therefore, when connecting and attaching a plurality of decorative plates 100 along the keraba, as shown in FIG. 9, as shown in FIG. 9, a connecting piece 110 having a shape that can be joined to the inner surface of the decorative plate 100 is connected. The decorative plates 100 and 100 are joined together by being inserted and fitted between the end portions of 100 and connecting the both end portions via the joint piece 110.

  If there is a gap in the joint portion between the decorative plates 100 connected in a row, the connection is insufficient and the decorative plate 100 is removed or the joint portion is distorted and the appearance is impaired. The inside of 100 may be submerged to corrode the inside. By inserting the joint piece 110 so as to straddle between both ends of the decorative plates 100 and 100 and fixing them on the inner surfaces of both ends, the gap between the joint portions is surely closed and the decorative plates 100 are firmly connected to each other. This makes it difficult for the above problems to occur.

However, since the joint piece 110 must be bent separately from the decorative plate 100 as a component for connecting the decorative plates 100 to each other, it is inevitable that the processing cost is increased, and the end portions of the decorative plate 100 are butted together. Therefore, there is a problem that the work of connecting with the joint piece 110 also takes time.
In addition, since the ends of both decorative plates 100 are abutted and connected at the joint portion between the decorative plates 100, it is necessary to accurately cut each decorative plate 100 to be joined to a dimension along the attachment surface such as keraba, There is a problem in that it takes time for processing at the construction site.

  In view of such problems of the prior art, the present invention can be used by joining a plurality of decorative plates along the roof periphery such as eaves and kerabas, without using separate parts such as joint members. It is an object of the present invention to configure the decorative plates so that the decorative plates can be connected and attached in a continuous manner reliably and cleanly with a simple operation.

In order to solve the above-mentioned problems, the present invention is a decorative board formed by bending a steel plate, and forms a continuous decorative surface by attaching a plurality of end portions together along the roof periphery. In the decorative panel for the roof that decorates the periphery of the roof,
It is formed into a cross-sectional shape having a plurality of substantially L-shaped bent portions by the bending process, and an end portion on the other side of the other decorative plate of the same shape and the same size as an end portion of the decorative plate. However, the outer surface or inner surface of the other side of the other decorative plate overlaps the inner surface or outer surface of the one end portion so that the ends of the two decorative plates are connected to each other. It is characterized by.

Since the decorative board of the present invention is formed by bending a steel plate, the contour shapes of the end faces of both ends thereof are the same, but the contour dimensions are slightly different, and the inner surface or outer surface of the end of the decorative board is different. It is formed so that the outer surface or inner surface of the end portion of another decorative plate can be fitted and connected.
The decorative plate can be joined by connecting the end of the other decorative plate to the end of the decorative plate by external or internal fitting, and no separate parts are required for connection. This can be done by a simple operation of fitting the parts together. In addition, the end portions of the decorative plate are not connected to each other as in the conventional example, but the end portions of the decorative plate are connected by external fitting or internal fitting, and the fitting portions of the end portions are connected to each other. Since there is an overlap margin of a certain amount of width, if the decorative plates to be joined are cut slightly longer than the dimensions along the mounting surface, the connected decorative plates can be attached exactly along the mounting surface In the construction site, the process of cutting the decorative plate into a dimension along the mounting surface with high accuracy is unnecessary.

The roof decorative plate having the above-described configuration is provided with a dimension shape in which the contour of the end surface on one side is narrowed by the approximate thickness of the steel plate than the contour of the end surface on the other side. Is preferred.
According to this, it is possible to connect the end portions of the decorative plates by externally fitting the end portions on the side where the contours of the other decorative plates are widened to the end portions on the side where the contours of the decorative plates are narrowed. it can. Since the size and shape of the contour of the end of the decorative plate that is narrowed and the end of the wider side of the decorative plate are only about the thickness of the wall, the ends of the decorative plate are fitted and connected to each other. The inner surface of the wide end is tightly bonded to the outer surface of the narrowed end so that the gap that can easily be formed at the joint between the ends is securely closed, and the decorative plates are firmly connected to each other. Can do.

  The decorative board having the above-described structure is formed by bending, and when formed using a press brake, during the process of bending the steel sheet with the press brake to form a plurality of bent portions of the decorative board, the steel sheet is elongated. Positioning the die and back gauge at the end on one side along the direction and the distance between the die and the back gauge at the end on the other side are different, and lowering the punch in that state and bending it Can be produced by a method of bending a steel sheet.

  Further, the decorative board of the present invention is a decorative board attached to a roof peripheral part such as a gable decorative board attached along the keraba or an eaves decorative board attached along the eaves, or a part outside the building other than the roof peripheral part. For example, it can be formed as a decorative plate for decorating the wall surface portion under the eaves.

  As the steel sheet to be bent into the decorative plate, a resin-coated steel sheet or the like that has been subjected to corrosion resistance processing such as covering the surface with a vinyl chloride resin sheet can be used. A resin-coated steel sheet coated with a 25-mm-thick vinyl chloride resin sheet and the back surface with a 0.1-mm-thick vinyl chloride resin sheet is suitable.
