DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unitized metal roofing material for roofing and a shingle structure thereof.

[0002]

2. Description of the Related Art Conventionally, a roofing material for roofing is made of a simple plate, and a required number and a required portion of the roofing material constitute a roofing plate (roofing). That is, the overlap fitting relies on the intuition of the constructor, and skill is required to perform construction without rain leakage.

[0003] In addition, since ancient times, those using a copper plate or the like as a roof plate have a high-class feel and have been in demand as such.
Today, the metal plate which has been subjected to makeup by etching or the like has begun to appear.

However, the problem with this metal plate is that, like the above, it requires skill in its construction, and because of the metal, noise such as rain noise is intense.

The present invention has been made in view of the above circumstances, and has an object to provide a unitized roofing material having a simple structure and capable of uniformly forming a metal surface, and having a sound deadening (sound insulation) effect. And

[0006]

In order to solve the above-mentioned problems, according to the present invention, a rectangular metal plate and a plastic plate are overlapped and joined, and the metal plate and the plastic plate are respectively A bent piece facing downward is formed on the front piece in an overlapping state, and a bent piece facing upward is formed on the rear piece in an overlapping state. The downward one is longer, the downward fold of the plastic plate is the same length as that of the metal plate, while the upward fold is longer than that of the metal plate,
The bent pieces on the front and rear sides of the plastic plate are formed with longitudinal ridges or grooves that fit together when they are stacked, and one of the left and right sides of the metal plate and its downward bent piece is A piece projecting a required length is formed over the entire length, and a mounting piece projecting from the bent piece is formed on the entire length of the rear side of the plastic plate.

According to the invention using the roofing plate of this construction, the above-mentioned roofing materials are arranged in the same axis in the vertical and horizontal directions, and the downward vertical direction of the roofing material is below the adjacent roofing material. The roof material on the upper side is fixed to the ground material by screws, etc., and the front folded piece of the upper roof material overlaps the front face of the rear folded piece on the lower roof material, and the ridge and groove fit together. On the other hand, in the vertical direction, the roof sheet structure is such that the adjacent piece of roof material overlaps the upper surface of the other metal sheet and the left and right side edges of the plastic sheet of both roof materials abut each other. is there.

As the above-mentioned metal plate, a conventionally used one such as a copper plate, a stainless steel plate, a titanium plate, an aluminum plate, a polyvinyl chloride steel plate, a decorative plate thereof, etc. can be appropriately used.
Further, the plastic plate material may be any material that conforms to the Building Standard Law, such as a weather-resistant porous fiber-reinforced plastic (FRP).

[0009]

In the construction, the roofing material constructed as described above is laid from the lower side of the base plate (eave side) to the upper side. At this time, in the longitudinal direction, the front side of the roofing material is fixed by fitting a ridge and a groove with the lower roofing material, and the rear side is fixed by screws or the like. In this connection, since the rear bent piece of the plastic plate is in an upright state, the rainwater is blocked by the bent piece and does not reach the rear, but flows down smoothly along the slope.

On the other hand, in the horizontal direction, the piece covers the upper surface of the metal plate, and the adjacent plastic plates abut against each other, so that flooding of the lower surface of the roof plate in the horizontal direction is reliably prevented.

[0011] In that state, the plastic plate is insulated
Exhibits a sound-absorbing (sound insulation) effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG.
A pattern P is formed by etching on the surface of a stainless steel plate 1 having a thickness of 255 mm and a thickness of 0.4 mm.
C: 25mm, d: 15mm fall or rise,
A metal sheet A for a roofing material having a bent piece 2 facing downward on the front side and a bent piece 3 facing upward on the rear side is obtained. The lowering and the starting are performed by press working.

On the other hand, the plastic plate B is made of a molded product of FRP, and has a width f: 370 m as shown in FIGS.
m, thickness: 5 mm, and is applied to the entire length of the metal plate A in the vertical direction on the back surface. The front edge is bent downward like the metal plate A to form a bent piece 12, while the rear edge protrudes by about 20 mm to form a mounting piece 14 and rises from the rear side of the metal plate A. A bent piece 13 is formed.

The bent piece 13 is further bent inward from the upper edge of the bent piece 3 of the metal plate A to form a locking piece (protrusion) 13 a, while the inner surface of the bent piece 12 is formed. Is formed with a laterally extending ridge, and the inside thereof forms a locking groove 12a. Therefore, as described later, as shown in FIGS. 1 and 5, when the roof material Q is roofed, the lower locking piece 13a engages with the lower locking groove 12a.

The metal plate A and the plastic plate B have weather resistance,
The roofing material Q according to the present invention is obtained by firmly joining with various adhesives in consideration of an adhesive or the like. The portion of the metal plate A protruding from the plastic plate B (the right end portion in FIG. 2) is a piece 4 to be described later.

Next, the roof R is roofed by the roof material Q according to the following procedure, which will be described with reference to FIGS. 1, 5 and 6. FIG.

As shown in FIG. 1, roof materials Q are arranged in the same axis in the vertical and horizontal directions. 20, the upper roofing material Q has its front bent pieces 2 and 12 overlapped with the lower surfaces of the rear bent pieces 3 and 13 of the lower roofing material Q, and the locking 13a is fitted into the groove 12a. Combine.

On the other hand, in the horizontal direction, the piece 4 of one roofing material Q adjacent to the roofing material Q is overlapped on the upper surface of the other metal plate A, and the left and right side edges of the plastic plate B of both roofing materials Q, Q abut each other. Let it. At this time, an adhesive layer with release paper is formed on the back surface of the piece 4 at the time of manufacturing the roofing material Q, or an adhesive is applied at the time of construction to join the metal sheet A with the adhesive layer. Is preferably ensured.

A waterproof layer (waterproof sheet) 21 of asphalt or the like is provided on the surface of the field material 20 to enhance waterproofness. Further, the eaves portion is covered with the eaves draining plate 22, and the eaves roof material Q is fixed at the front edge thereof by an auxiliary mounting piece 23 in which the mounting piece 14 and the bent piece 13 are separately formed.

Further, the cap portion is covered with a ridge 24 made of a metal plate. As shown in FIG. 6, a metal fitting 25 is attached to both sides of the roof, and a backup material 26 and a sealing material 27 are interposed between the metal fitting 25 and the roof material Q.

Adhesives, sealing materials, and the like are interposed between the overlapping portions and gaps of the roof R, such as between the roofing materials Q and between the roofing materials Q and between the roofing material Q and the eaves draining plate 22.

The surface of the roof R thus roofed is made of a metal plate A, giving an atmosphere of the metal. On the other hand, a plastic plate B
This provides a heat insulating effect and a sound insulating effect. For this reason, the heat insulation property of the metal roof,
Solves the problem of sound insulation.

It is needless to say that the dimensions of the roofing material Q are not limited to those of the embodiment, but may be appropriately determined in consideration of manufacturability, transportability and the like. The plastic plate B has a plurality of plastic layers, for example, a metal plate A.
Can be configured such that an object in contact with the FRP is overlapped with a foamed resin (polyethylene or the like) which is more porous than the FRP. The more porous, the better the sound insulation and heat insulation effect. Contrary to these configurations, a more porous one may be used as the metal plate A side.

[0024]

According to the present invention, since the present invention is constructed as described above, and it is possible to perform uniform construction with a simple structure, roofing of a metal surface can be performed at low cost.

Further, the construction is facilitated by joining the plastic material, and the heat insulating material and the sound insulation are improved.
