Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an exterior wall structure that forms a wall as an exterior material or an interior material for a building or structure. More specifically, the present invention relates to an exterior wall structure in which the decorative surface forms a wall body with an unprecedented design and has significantly improved waterproofness.

[Conventional technology]

This type of exterior wall structure is disclosed in Japanese Utility Model Application Publication No. 59-157010, and the siding board (hereinafter simply referred to as board) used in this type of exterior wall structure is disclosed in ■ Utility Model Application Publication No. 52-1983.
Publication No. 135322 and Japanese Utility Model Publication No. 178917/1983 are known.

[Problems to be solved by the invention] However, in ■, great care and precision are required to connect the boards themselves, and in ■, two types of boards must be used to form the wall. In addition, the workability was significantly reduced, and in case (2), there was a disadvantage that the design was inferior. Furthermore, since the decorative surfaces of the materials (■) to (■) were not reinforced, there was a disadvantage that the board could not be formed wide.

[Means for solving problems]

The present invention improves workability and economical efficiency by forming a step piece on a decorative surface portion and providing a plurality of decorative pieces to form a board with a wide width, and the width of adjacent decorative pieces divided by the step piece. By setting the ratio of 1:9 to 10, decorative joints with unprecedented width are formed in the wall formed by the board, improving the design, and connecting parts of the same shape are formed at both longitudinal ends of the surface material. A board that can be used to form a wall on either the left or right is fixed onto the frame using nails, etc., and a locking body having fitting parts at both ends is fixed to the connecting part, and the locking body The present invention proposes an outer wall structure in which a long decorative cap having locking portions at both ends is engaged and fixed, and a waterproof caulking material is planted between the connecting portions of the boards.

〔Example〕

An embodiment of the outer wall structure according to the present invention will be described in detail below with reference to the drawings. That is, FIG. 1 is a sectional view showing the above-mentioned outer wall structure, and FIG. It is composed of D (referred to as material). To explain further, board A
As shown in Figure 2 (a), the upper surface material is a metal plate such as colored steel plate, copper plate, stainless steel plate, aluminum plate, galvalume steel plate, galfan, clad steel plate, damping steel plate (sandwich steel plate), or synthetic plate. The resin is formed by press molding, extrusion molding, roll molding, injection molding, etc. to form a decorative surface portion 1, a connecting portion, and a cross section approximately like a gutter. A step piece 5 is provided along the longitudinal direction.Since this step piece 5 is provided along the longitudinal direction of the board A in the middle of the decorative surface portion, the mechanical strength of the decorative surface portion 1 is strengthened and the board A is formed wide. This is useful for preventing warpage, twisting, and unevenness, and for maintaining flatness.Furthermore, the stepped piece 5 has a decorative surface area of 1:9 to 1 in the ratio of the decorative piece 2a.
, 2b. Therefore, the wall formed by the board A creates an unprecedented three-dimensional effect due to the shadow created by the stepped piece 5 and the unprecedentedly large ratio of the decorative pieces 2a and 2b. Reference numeral 3.4 denotes side walls, which are formed by bending both edges of the decorative surface portion 1 in the longitudinal direction inward perpendicularly or inclinedly. Connecting section, -(

Note that this type of additive may be surface-treated with a surfactant. Furthermore, examples of synthetic resin foams include polyurethane foam, polyurea foam, polyimide foam, phenol foam, and polyisocyanurate foam. In particular, it is preferable that this synthetic resin foam forms a carbonized layer under high heat. In addition, the core material 12
In this method, raw materials are discharged, molded, hardened, and self-adhesive to fill the molded product, or a molded product is attached using an adhesive. 13
is a back material that covers at least the back surface of the core material 12 in the longitudinal direction with the self-adhesive property of the core material 12 or with an adhesive interposed, and mainly has fire retardant, waterproof, weather resistant,
It has at least one function of improving aesthetics and strength. Examples of materials include kraft paper, asbestos paper, waterproof kraft paper, waterproof asbestos paper, metal foil (A I SPb% C0% Fe
(S stainless steel), glass fiber nonwoven fabric, synthetic resin sheet, and sheet-like materials laminated or vapor-deposited with one or more of these. It should be noted that embossing, wavy patterns, etc. can be formed on the surface material at four locations with arbitrary widths, and the design can be further improved by installing such patterns.
