Description

The present invention relates to a building material panel suitable for use in a roof, a wall, or the like of a building structure, and a connection structure using the building material panel.

Sandwich panels with a laminated structure in which a heat insulating material is sandwiched between two metal plates have the advantages of being lightweight, high strength, high heat insulating, and able to efficiently manufacture long materials, and have the advantages of being able to efficiently manufacture long materials, such as factories, warehouses, and general housing. It is widely used as an outer wall material and roofing material for commercial facilities such as apartment houses and stores, and building structures such as livestock barns.

In particular, as a sandwich panel in which a cover cap is used to hide the jointed portion of the panel in appearance, for example, Patent Document 1 is referred to.

By the way, the conventional sandwich panel has a problem that it is necessary to separately prepare a member for fixing the cover cap and efficient construction cannot be performed, and the cover cap itself is from the outer surface of the sandwich panel. Since it is arranged so as to project outward, it is not preferable in appearance and improvement is required.

It is an enlarged view of BB arrow view, and FIG. 3 is a view which showed the CC cross section of FIG.

In constructing the wall of a building structure, it is premised that a plurality of building material panels according to the present invention are used, and the other building material panels and other building material panels referred to in the present invention are the building material panels according to the present invention. It means something that has the same composition. The width dimension and length of the building material panel can be changed arbitrarily, and are not limited to those shown in the figure.

Reference numeral 1 in FIGS. 1 to 3 is a panel body having a laminated structure in which the core material A is sandwiched between the exodermis material B and the endothelial material C. The panel body 1 has a contour shape defined by a pair of short edge edges 1a and 1b and long edge edges 1c and 1d connected to the short edge edges 1a and 1b.

As the core material A, a foamed plastic-based or mineral fiber-based heat insulating material having a thickness of about 50 to 150 mm can be used, and the outer skin material B and the endothelial material C are zinc-plated with a thickness of about 0.2 to 1.0 mm. Steel sheets, aluminum-zinc alloy plated plates, stainless steel plates, aluminum plates, copper plates or their coatings and coated steel plates can be used. The thickness of the core material A is preferably about 75 mm, and the outer skin material B and the endothelial material C are preferably those having a thickness of about 0.5 mm. The exodermis material B is located on the outer surface of a wall or the like, and the endothelial material C is located on the mounting base side of the furring strip or the like.

Further, reference numeral 2 is provided on the short end edge 1a, and as shown in FIG. 4, the convex portion 3 which is fitted into the concave portion 3'of another building material panel to form an actual joint is the other short end. It is a concave portion provided on the edge 1b and fitted to a convex portion 2'of another building material panel to form an actual joint. The convex portion 2 and the concave portion 3 have a laminated structure in which a resin block D arranged adjacent to the core material A is sandwiched between the outer skin material B and the endothelial material C, whereby the strength of the jointed portion can be increased. It has become like. The convex portion 2 is set to a size and shape that can be fitted to the concave portion 3, and the concave portion 3 is set to a size and shape that can be fitted to the convex portion 2, and the outer skin material B and the endothelial material C are set. Is formed by subjecting to molding.

Further, reference numeral 4 is a joint portion which is connected to the long end edges 1c and 1d in a stepped-down manner to form a cover cap installation seating surface d which will be described later. The joint portion 4 has a recess 4b in which the leg portion of the cover cap is fitted to the protruding end surface 4a and the main body portion of the cover cap is fixedly held on the installation seat surface d. As the recess 4b, one having a V-shaped inclined wall can be applied, but the cross-sectional shape is not limited to the one shown in the figure.

Further, reference numeral 5 is a rib provided on the installation seat surface d. The rib 5 abuts on the back side surface of the main body portion of the cover cap and holds the cover cap flush with the outer surface of the panel main body 1. Here, the case where one rib 5 is provided for one joint portion 4 is shown, but the number of ribs 5 may be two or two or more.

5 (a) and 5 (b) are external perspective views schematically showing a cover cap 6 suitable for use when constructing a connection structure such as a wall using a building material panel having the above structure. The cover cap 6 is a main body portion 6a made of a plate-like body that covers the installation seat surface d, and is suspended and held on the back side surface of the main body portion 6a in a cantilevered state, and can be fitted into the recess 4b by springback. It is possible to apply a leg portion 6b composed of a hook-shaped piece. The cover cap 6 is preferably formed by bending a single plate material into a T shape.

In order to construct a connecting structure such as a roof and a wall of a building structure by using the building material panel according to the present invention and the cover cap 6 described above, as shown in FIG. 6, the endothelial material side of the building material panel is hated. Along with facing the mounting base 8 on which the mold member 7 is installed, the joint portion 4 of each building material panel is positioned so as to sandwich the hat mold member 7 in a butt state. Then, a drill screw is driven into one or more places of the installation seat surface d of the joint portion 4, the panel main body 1 is fixed to the mounting base 8, and the cover cap 6 is passed through the gap formed between the joint portions 4. The leg portion 6b may be inserted to fit the leg portion 6b into the recess 4b, and the main body portion 6a of the cover cap 6 may be fixedly held to the installation seat surface d, whereby a base member or a building material may be used. The connecting structure is constructed without the cover cap protruding from the outer surface of the panel. FIG. 7 shows an external perspective view of a part of a connection structure constructed by using the building material panel and the cover cap 6 according to the present invention.

By forming the recess 4b into a V-shaped inclined wall and the leg portion 6b of the cover cap 6 as a hook-shaped piece, the cover cap 6 has a leg portion 6b when the leg portion 6b is fitted into the recess 4b. The tip of the recess abuts on the inclined wall of the recess 4b to prevent it from coming off.

Prior to attaching the cover cap 6, an annular gasket 9 can be arranged in the gap, whereby the water stopping property can be improved.

As the hat-shaped member 7, it is possible to use a member that is made of the same material as the outer skin material B and the endothelial material C and has a folded-back portion 7a whose edge edge can abut on the endothelial material C of the panel body 1 in the assembled state. It is possible, and the water blocking property can be improved by installing the standard sealing material 11 between the hat type member 7 and the endothelial material C. However, if there is no particular problem with the water stopping property, the hat type member 7, It is also possible to omit the arrangement of the standard sealing material 11.

A standard sealing material 10 made of foamed silicone that can stop water by a repulsive force may be arranged between the main body portion 6a of the cover cap 6 and the installation seat surface d.

According to the present invention, a building material panel capable of efficiently constructing a roof, a wall, or the like having a flat outer surface without using a base member while ensuring excellent heat insulation, waterproofness, and workability, and a building material panel thereof. A connection structure using a building material panel can be provided.
