Abstract

PROBLEM TO BE SOLVED: To mechanically strengthen a roof copper plate, and reduce a cost by forming plywood by arranging a steel plate on the reverse of a copper plate by soldering or an adhesive, or arranging a dissimilar metallic plate on the reverse side of the copper plate. SOLUTION: While spraying a mist flux 3 and powder solder 4 between a copper plate 1 and a galvanized sheet iron 2, they are wound while bringing them into pressure contact with each other by a heating roller 5 and a pressurizing roller 5. Or while spraying an adhesive between the copper plate 1 and the galvanized sheet iron 2, they are wound while bringing them into pressure contact with each other by a pressure contact roller. A mold such as a metallic roof tile is simultaneously molded by performing an adhesive between the copper plate 1 and a dissimilar metallic plate at molding time, or is adhered by being put together after molding. Workability is improved by sticking them together by putting the copper plate 1 on the obverse and a steel plate on the reverse, and a durable copper plate roof can be laid. Therefore, it is useful for saving a cost and resources to finish a strong copper layering roof as well as to apply paint with every several years differently from color galvanized sheet iron.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical strengthening and an economical effect of a copper sheet for a roof.

[0002]

2. Description of the Related Art Conventionally, a copper plate has been used for roofing.

[0003]

Conventionally used copper plates have a problem in that, particularly during forming, the formed part may be bent or crushed. In addition, copper plates are expensive and use thick copper plates for reinforcement. It is very uneconomical.

[0004]

[Means for Solving the Problems]

 1. A steel plate is attached to the back of the copper plate. 2. The molded product may be formed by overlapping.

[0005]

[Function] The workability is good and the long-lasting copper plate roof can be laid by using the copper plate as the front surface and the steel plate attached to the back surface.

[0006]

An embodiment of the present invention will be described. Figure 1, Fog flux (3) between copper plate (1) and galvanized plate (2)
And the powder solder (4), while being pressed against the heating roll (5) and the pressure roll (6), and winding in the direction of the arrow. In FIG. 2, the pressure rolls (14), (1) are sprayed with an adhesive (13) between the copper plate (11) and the galvanized steel plate (12).
5) Winding in the direction of the arrow while pressing in contact. In addition, a molded product such as a metal roof tile may be simultaneously molded by applying an adhesive between a copper plate and a dissimilar metal plate at the time of molding, or may be bonded together after molding.

[0007]

【The invention's effect】

1. By providing a steel plate on the back of the copper plate, a robust copper-roofed roof can be finished. 2. It is possible to reduce the weight of the expensive copper plate by making it thinner than conventional products, reduce the weight and reduce the price, and finish the copper-roofed roof which is robust. 3. Unlike color tin, it greatly saves the cost and resources of applying paint every few years.

Claims (3)

[Claims] 1. A copper sheet reinforced roofing material in which a steel sheet is soldered to the back surface of a copper sheet to make a plywood. 2. A copper sheet reinforced roofing material in which a steel sheet is bonded to the back of the copper sheet with an adhesive material to form a plywood. 3. A molded product for a copper sheet reinforced roof having a dissimilar metal sheet provided on the back side of the copper sheet.
