DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the corner structure according to the present invention will be described in detail below with reference to the drawings. FIG. 1 and FIG. 3 are a representative example of the corner structure according to the present invention as shown in FIG. 2 and FIG.
FIG. 3 is a cross-sectional view showing a corner member, which includes a corner member A, a backup material B, a sealing material C, a dry wall material D, a wall base α, and a fixture β.

The material of the corner member A is a metal plate such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plate, enamel steel plate, clad steel plate,
Laminated steel plates (PVC steel plates, etc.), sandwich steel plates (damping steel plates, etc.), etc. (including, of course, colored metal plates coated in various colors) are formed into various shapes by roll molding, press molding, extrusion molding, etc. Or
A ceramic plate, an ALC panel, an extruded cement plate, or other ceramic-based extruded material, or a synthetic resin plate formed by roll molding, extrusion molding, injection molding, etc. It is effective.

The corner member A has two facing surfaces 2 facing each other at a substantially right angle, a facing surface portion 1 having a concave groove 3 in which the vicinity of both end portions of the facing surface 2 is concavely recessed, and both end portions of the facing surface portion 1. Is formed in a long shape from an abutment surface 4 including an upper surface 5 bent in the direction of the groove 3 and a side surface 6 in which the tip of the upper surface 5 is bent outward.

The decorative surface portion 1 covers the end portion of the corner portion of the dry wall material D to prevent the end portion of the dry wall material D from being exposed to the surface, improving the aesthetic appearance of the corner portion, and the dry wall material. This contributes to prevention of deterioration of D.

As shown in FIGS. 2 and 4, the concave groove 3 is for fixing the corner member A to the wall foundation α, and the head of the fixing tool β projects above the surface of the decorative surface 2. The recessed groove 3 is filled with a backup material B and a sealing material C, which will be described later, to prevent the fixing tool β from being exposed to the outside, and to prevent the corner member A from being deformed by driving the fixing tool β. The corrosion resistance can be improved by preventing the exposure of the installation surface.

Reference numeral 3a is a groove which is formed so as to ensure the position where the fixing tool β is set and to prevent the fixing tool β from being displaced left and right.

The upper surface 5 functions as a decorative surface of the dry wall material D as well as a bonding base of a sealing material C described later.

The side surface 6 functions as an insertion base for the backup material B, which will be described later. Since the forming position is always constant, the backup material B is easily inserted and the workability is improved. . Further, 6a is a tongue piece, which is formed to prevent damage due to a cut end.

The material of the backup material B is generally commercially available such as foamed polyethylene, chloroprene rubber, EPT rubber, synthetic rubber beads and bond breaker. Further, as the material of the backup material B having fire resistance, rock wool felt, glass wool, asbestos, gypsum board, ALC, water glass bond, various inorganic foams, ultra high density phenol foam, inorganic fire resistant caulking agents, etc. Alternatively, it is a material having indeterminate fire resistance. Further, by coating various primers instead of the backup material B, it is possible to prevent the sealing material C from adhering at three points.

The sealing material C is a silicone type (reaction curing type, moisture curing type), modified silicone type (reaction curing type),
Fire resistance of polysulfide type (reaction curing type), polyurethane type (reaction curing type, moisture curing type), SBR type (dry curing type), acrylic type (dry curing type), etc., or foams thereof or inorganic type It is formed from one or more kinds of the sealing material C having the above-mentioned, and has at least elasticity and waterproofness. The sticking and forming are self-adhesive, or integrally formed through an adhesive or by utilizing elastic deformation. Of course, it is also possible to improve the fire resistance by mixing a flame-retardant material into these fillers.

The dry wall material D is, for example, metal siding,
Double-sided metal steel panel, various ceramic siding, PC
It consists of a board, a ceramic board, a wood board, etc., and may be either vertical or horizontal.

Next, a construction example will be briefly described. Therefore, as shown in FIG. 2, first, it is formed on a steel frame base such as C type, square type, H type steel or the like, or a wooden base such as studs, main columns, furring strips, etc. (not shown), or a wall base α made of a waterproof sheet or the like. The bottom surface of the concave groove 3 is brought into contact with the corner portion of the dry wall material D, and the concave groove 3 is fixed by a fixing tool β such as a screw. Next, the groove 3 and the space between the contact surface 4 and the decorative surface of the dry wall material D are filled with the backup material B and the sealing material C to form the projected corner portion as shown in the drawing.
