Description

The present invention relates to an exterior accessory used for a corner portion (protruding corner portion / entrance corner portion) and a vertical joint portion formed by attaching end portions in the longitudinal direction of an exterior material used for buildings and structures.

In general, a wall is formed in a horizontally stretched state using a sandwich structure exterior material with a metal plate as a surface material, a synthetic resin foam as a core material, and a sheet-like material as a back surface material, or an exterior material made of an inorganic material. When formed, a joint portion is formed by abutment of the exterior material in the longitudinal direction. In the corner portion, an L-shaped corner material or a corner material is struck into the brain, or two members, a siding board and a makeup cap, are used. There is a method of forming by fitting. (For example, see Patent Documents 1 to 3).

However, Patent Document 1 relates to a corner portion structure in which a decorative surface portion and an engaging portion that protrudes toward the back surface are integrally formed, but it is necessary to form a plurality of engaging pieces in order to form integrally, and the strength is increased. There was a problem. In addition, the accessory of Patent Documents 2 and 3 is an exterior accessory in order to form the design of the exterior material in which a plurality of concave makeup joints are formed on the decorative surface without being interrupted by the joint portion of the exterior material. In order to eliminate the trouble of processing and molding a single plate member (one member) in Patent Document 1, two surface portions serving as a cover material are formed. It is formed by. However, although molding and processing are easy, there is a risk that the covering material and the protrusion are separated because they are formed of two members.

In order to solve such disadvantages, the present invention provides a vertical plane fixed piece, a siding plate that projects a substantially central portion to the outdoor side to form a fitting portion, and a vertical surface on which a plurality of decorative joints are formed. An exterior accessory formed from two members: an engaging portion that projects a substantially central portion of the decorative face portion toward the indoor side, and a makeup cap that forms a space at the base portion of the engaging portion on the back surface portion of the makeup joint To do.

As described above, according to the exterior accessory according to the present invention, (1) strength can be improved because the engaging portion can be formed continuously. (2) Since the engaging portion can be formed continuously, the attachment strength with the siding plate is improved. (3) Since the decorative cap can be formed with one member, the strength is improved and the cost can be reduced. (4) No complicated molding process is required. There are features and effects.

Hereinafter, representative examples of an exterior accessory according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing a siding board B and a decorative cap C used for an exterior accessory A according to the present invention, FIG. 2 is a perspective view showing the cosmetic cap C, and FIG. FIG. 4 is a perspective view showing a construction state of the exterior accessory A, FIG. 5 is a sectional view showing the exterior material D, A is an exterior accessory, B is a siding board, and C is A cosmetic cap, D is an exterior material, α is a wall base, and β is a fixture.

More specifically, the exterior accessory A and the lining plate B are metal thin plate materials such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plates, galvalume steel plates, enameled steel plates, clad steel plates, laminated steel plates ( PVC and other steel plates, sandwich steel plates (damping steel plates, etc.), synthetic resin plate materials such as vinyl chloride resin and polycarbonate resin (including, of course, color plates coated with various colors) are roll-formed and pressed. It is formed into various shapes by notching or the like.

The lining plate B is a long plate material, and is formed of a vertical portion 1 and a fitting portion 4 as shown in FIG. More specifically, the vertical portion 1 is formed by a vertical flat fixed piece 2 and a tongue piece 3 whose tip is bent into a helical shape. Further, the fitting portion 4 has two guide pieces 5 formed by bending the substantially central portion of the vertical portion 1 upward, and the tips of both guide pieces 5 are bent inward and the tips bent inward. A fitting groove 6 having a substantially U-shaped cross section is formed, and a fitting claw 7 protruding into the fitting groove 6 is formed. This fitting part 4 is a part which engages the engaging part 9 of the cosmetic cap C mentioned later.

The decorative cap C is determined by the decorative surface and the cross-sectional shape of the exterior material D. When the exterior body D as shown in FIG. 5 is used to form a wall, FIGS. 2 (a) and 2 (b). The decorative cap C is as shown in (a diagram obtained by rotating FIG. 2A 90 degrees to the right).

More specifically, the cosmetic cap C has a narrow-width decorative surface 8a formed in the same shape as the external decorative surface D1 and the external decorative joint D2 of the external material D, and a concave and horizontal decorative joint 8b formed between the decorative surfaces 8a. The decorative surface portion 8 and an engaging portion 9 projecting in the longitudinal direction at the center of the back surface of the decorative surface portion 8 are formed. The decorative surface portion 8 covers the end of the exterior material D as shown in FIG. It is a part that improves design and waterproofness. Of course, the makeup joint 8b and the exterior makeup joint D2 of the exterior material D shown in FIG.

The engaging portion 9 includes a rising portion 10 that is bent at an appropriate interval of approximately 45 degrees at a position capable of protruding to the center of the back surface of the decorative surface portion 8, and an engaging piece 11 that protrudes outward near the tip of the rising portion 10. Thus, the engaging piece 11 is engaged with the fitting claw 7 of the lining plate B, and fixes the decorative cap C to the wall base α. Reference numeral 12a denotes a fixing hole, which is a portion for fixing the upper end of the decorative cap C to the wall base α by the fixing tool β. The inner surface angle on the engaging portion 9 side between the decorative surfaces 8a is preferably 90 degrees or less.

Reference numeral 13 denotes a space, which is formed by cutting out the base portion of the engaging piece 11 of the engaging portion 9 formed on the back surface portion of the decorative joint 8b.

The space 13 prevents the molding distortion of the decorative joint 8b processed into a concave shape from affecting the engagement piece 9, improves the strength by allowing the continuous engagement portion 9 to be molded, and improves the molding accuracy. It is intended to improve, and is formed from the root of the engaging portion 9 to the back surface of the decorative surface portion 8 and is formed to be larger than the width of the decorative joint 8b.

The waterproof piece 12 is formed by protruding the upper end portion of the decorative surface portion 8 further upward, the left and right end portions are inserted into the connecting grooves between the exterior materials D, and the portion protruding upward in the center is the joint. It is a part which improves the waterproof function between the upper and lower makeup caps C between the parts.

The joint cover piece 14 is formed by bending the lower end portion of the decorative surface portion 8 inward, and covers the lateral joint portion of the exterior material D.

As shown in FIG. 5, the exterior material D is a long exterior material D having a male-female fitting structure in which an exterior decorative surface D1 and an exterior decorative joint D2 are formed. The metal-based siding material, ceramic-based siding material, ceramic, Etc. are molded.

Of course, the corners of each surface of the makeup cap C are formed by chamfering so as not to become acute angles, so that there is no injury.

What has been described above is the exterior accessory A that uses the exterior accessory according to the present invention as a corner corner extension, but it is Y-shaped as shown in FIGS. 6 (a) and 6 (b). It is also possible to form a T-shaped vertical joint accessory.
