Description

[Detailed explanation of the idea] Industrial applications This invention relates to metal exterior materials.

Conventional Technology Exterior materials are required to prevent the infiltration of rainwater, have excellent fire resistance and durability, and have a beautiful appearance.

Traditionally, wood, inorganic plates, metal plates, and the like have been used as exterior materials, but wood is difficult to obtain and is expensive, and has a decisive drawback in terms of fire resistance. Inorganic board (e.g. wood wool cement board)
In addition to being heavy and difficult to work with, special measures such as using caulking material are required to prevent rainwater from entering.

On the other hand, metal plates that have been surface-treated to have corrosion resistance, for example, can be easily processed to resist the infiltration of rainwater, are lightweight, can be produced industrially, and are advantageous in terms of cost. Furthermore, by lining with a heat insulating material such as gypsum board, the fire resistance of the metal is further increased, and the heat insulating property, which is a disadvantage of metal, is also imparted, making it a more preferable exterior material.

Problems to be Solved by the Invention The present invention provides metal siding that further increases the durability of horizontal siding lined with gypsum board.

Means for Solving the Problems The present invention is horizontal metal siding lined with gypsum board, which has a gap at the lower end of the gypsum board that facilitates drainage when the metal siding is attached to an exterior wall. .

The present invention will be explained below using the figures.

Figure 1a is a diagram showing the usage state in which two pieces of metal siding of the present invention are vertically fitted, and Figure 1b
is an explanatory diagram showing the vertically fitted state by cutting the vertically fitting portion 1 shown in Fig. 1a horizontally, and Fig. 1c is an explanatory diagram showing the vertically fitted state.
The metal siding shown in Figure 1a is cut vertically to show the cross-sectional shape of the siding, and the top,
FIG. 7 is an explanatory diagram also showing a downwardly fitted state, that is, a horizontally fitted state.

As is clear from the figure, the upper end of the siding is formed with a protrusion 3, a U-shaped groove 4, and an ear 5, and the lower end is formed with a U-shaped groove 6, an inverted recess 7, and a hem 8.
is formed.

The left and right ends of the siding are bent inward and then folded back to form ears 9 that slightly protrude outward.

When using the siding on the outer wall of a house, as shown in Figure 1a, hold the siding so that the protrusions 3 on the top end are horizontal to the left and right, and attach several places on the ears 5 with nails, screws, etc. Fix it to a pillar, etc. (not shown) on the back.

Then the reverse recess 7' at the lower end of another siding.
are inserted into the convex portion 3 at the upper end of the fixed siding, and the male and female fittings are made.

Since the lug 5 forming one side of the U-shaped groove 4 of the fitting part at the upper part of the siding has a sufficient length to be fixed to a pillar etc., rainwater can leak from the outside surface 10 of the siding to the fitting part. It flows down to the siding outer surface 10' located below.

The left and right fitting (vertical fitting) when attaching to the outer wall of the metal siding is a female-male fitting as shown in FIG. 1b, and can be easily fitted by sliding the metal siding to be attached later. After fitting, the fitting part 1 is caulked to prevent rainwater from entering.

However, in the unlikely event that rainwater intrudes due to aging of the caulking part, the rainwater will go around the back side of the expanded siding and flow down from the drain 11 provided on a part of the side of the U-shaped groove 6 at the bottom of the siding. The rainwater flows down onto the siding outer surface 10' located at the siding surface 10' and is drained away.

In the case of metal siding that is lined with gypsum board 12, the gypsum board absorbs water and deteriorates its adhesive strength with the metal plate, insulation properties, etc., so remove the water that has entered as quickly as possible without coming into contact with the gypsum board. It is desirable to discharge it.

As a result of considering various means for quickly removing water that has once entered the plasterboard without it coming into contact with the plasterboard, it was discovered that it would be better to provide a gap 13 with a drainage hole at the bottom end of the plasterboard, and the present invention was completed. It is.

However, the provision of the lever gap also produced a side effect. In other words, when lining a gypsum board without creating a gap as in the present invention, the horizontal fitting part of the siding is once formed, the horizontal fitting part is opened outward, the gypsum board is inserted, and the horizontal fitting part is again fitted. However, in the case of the present invention, after completing the forming of the horizontal fitting part with forming rolls, the horizontal fitting part can be left as it is without opening it outward again. In this way, the gypsum board can be inserted at a slight angle and placed on the predetermined back side of the siding, which has been previously coated with adhesive, making it easy to manufacture.

Effects of the invention If the metal siding of this invention is used as an exterior material, even if rainwater enters the back side,
The backed gypsum board has very little chance of absorbing water, greatly increasing its durability, which is important as an exterior material. In addition, the manufacturing process is simplified and productivity can be improved.
