Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to architectural board materials used as exterior wall materials and roofing materials for buildings.

[Conventional technology]

Lead plates and other metal plates are attached to the exterior walls and roof materials of buildings, and the lead plates provide a sound insulation effect.
A construction plate material in which a lead plate is reinforced with another metal plate is known from Japanese Utility Model Application Publication No. 54-133903. In this case, when trying to manually form eaves gutters or valley gutters according to the shape of the building's roof using a hard metal plate such as a steel plate, the bending process is extremely difficult. It is difficult and has the disadvantage that well-finished eaves and valley gutters cannot be obtained.

[Problem that the idea aims to solve]

The present invention aims to solve these problems and provide an ideal construction board material that is less likely to cause dew condensation.

[Means to solve the problem]

The architectural board material according to the present invention is a construction board material in which a hard metal plate such as an iron plate 2 or a stainless steel plate is attached to the back side of a lead plate 1, and the hard metal plate has a large number of transparent holes in the longitudinal direction. The holes 3 are arranged in a column, and the holes 3 in the column are bored at intervals in the width direction of the hard metal plate, and a decorative coating film 4 is applied to the outer surface of the lead plate 1.
A rust-preventive coating film 5 is formed on the outer surface of the hard metal plate.

[Effect]

A hard metal plate can be easily bent by hand if it is bent at the positions of the through holes 3 arranged in tandem in the longitudinal direction. In addition, since the vertical rows of the through holes 3 are arranged at intervals in the direction perpendicular to the longitudinal direction, they can be bent into a shape suitable for the site, and the vertical positions of the through holes 3 can be easily positioned through the anti-rust coating. It is confirmed that

【Example】

An embodiment of the present invention will be explained based on the drawings. 1 is a lead plate, 2 is an iron plate attached to the back of the lead plate 1 using adhesive, and 3 is a large number of holes drilled at intervals in the iron plate 2. It is a through hole. The through holes 3 are long holes or circular holes arranged in a straight line in the longitudinal direction of the iron plate 2 and arranged in vertical rows at predetermined intervals in the horizontal direction, as shown in Fig. 3 A and B. It may be perforated.
Reference numeral 4 indicates a decorative coating film applied to the outer surface of the lead plate 1;
5 is an anti-rust coating applied to the outer surface of the iron plate 2. As the hard metal plate, a stainless steel plate, an aluminum plate, a copper plate, a galvanized iron plate, etc. are used depending on the purpose.

【effect】

The architectural board material according to the present invention is made up of a lead plate and a hard metal plate, so when forming eaves gutters or valley gutters by bending the lead plate on top, even if the bending process Even if the coating on the surface sometimes cracks or peels off, the hard metal plate will not rust because it is covered with a lead plate, and since the lead plate is supplemented with strength and hardness by the hard plate, it can be thin. It is possible to use the following. Furthermore, even when used as a roofing material, the spacing between the purlins can be kept as wide as in the past since it does not bend. In particular, in the present invention, since a large number of through holes are bored in a hard metal plate, the weight can be reduced, and the through holes are arranged vertically along the longitudinal direction of the metal plate. Because they are arranged at intervals in the horizontal direction,
If the hard metal plate is bent vertically at the position of the through hole, the hard metal plate can be easily bent by hand without using a machine or jig. Therefore, it is possible to form eaves gutters and valley gutters with cross-sectional shapes and sizes that suit the site. In addition, when a glass fiber board, gypsum board, etc. is laminated on a hard metal plate, an air chamber is formed between the glass fiber board, gypsum board, etc. and the hard metal plate due to the through holes, so Even when the metal plate is cooled, the temperature of the air in the air chamber does not cause a sudden drop in temperature, so dew condensation does not easily form on the bottom surface of the hard metal plate.Furthermore, due to the through holes,
This has the effect of improving the adhesion effect with glass fiber boards and the like.
