Description

TECHNICAL FIELD The present invention relates to a corner member for covering a corner portion of a dry type exterior material when forming an outer wall of a building or a structure.

[Conventional technology]

In general, when an outer wall of a building or a structure is formed by a dry exterior material, an L-shaped corner member has a structure in which a nail or the like is hammered from its decorative surface to fix the corner member. As a result, there is a defect that the decorative surface is roughened by casting or is damaged and the coating film is damaged and rusted. In addition, since the nail head is exposed on the decorative surface for waterproofing, there is a disadvantage that water or the like penetrates through the nail hole portion and corrodes the nail, the dry exterior material, and the base material. For this reason, a corner member has been used which engages with the elasticity of the corner cover using a mounting tool. However, since this kind of corner member fixture is fixed on the end of the dry type exterior material via a nail, when rainwater leaks from between the corner cover and the dry type exterior material, it immediately penetrates to the nail hole portion,
Nails, fixtures, dry exterior materials, base materials, and even corner covers could be corroded.

[Object of the Invention]

In order to eliminate such drawbacks, the present invention provides a corner cover fixture having engaging pieces on a corner cover mounting member having fitting grooves formed on both sides of a fixed surface opposed to each other at an angle of about 90 °. The present invention provides a corner member that covers the end portion of the corner portion of the dry-type exterior material by engaging with each other.

[Structure of Invention]

Hereinafter, the corner member of the dry-type exterior material according to the present invention will be described in detail with reference to the drawings. FIG. 1 shows a corner member (hereinafter, simply referred to as a corner member) α of a dry type exterior material according to the present invention.
3A and 3B show an example of a projected corner, where A is a corner cover mounting tool (hereinafter simply referred to as mounting tool), and B is a corner cover (hereinafter simply referred to as cover). More specifically, as shown in FIG. 2 (a), the fixture A is made of metal, synthetic resin, or the like, and is formed by using one or more of roll forming, extrusion forming, and the like. Guide part 5, fitting part

The shape of the fitting piece 8 is not limited to the triangular shape as shown, but may be a quadrangular shape, a semicircular shape, or the like.
It may be formed on the vertical surface 3, though it depends on the forming position of 12. The cover B is a decorative surface 10 as shown in FIG. 2 (b).
And a cross section of approximately L from the engaging portion 13 hanging from one edge of the decorative surface 10.
It is formed in a letter shape. More specifically, the makeup side
10 is a cosmetic surface, a waterproof surface, which covers the end of the dry exterior material β,
The portion that functions as an end covering surface, the engaging portion 13 includes the insertion surface 11 and the engaging piece 12, and engages with the fitting portion 9 of the fixture A to fix the cover B to the fixture A. Is. Reference numeral 14 denotes a tongue piece, which functions as a portion for preventing danger and strengthening engagement force, and is provided as necessary. 15 is the side, 16
Is a stable surface, clarifies the boundary between the dry exterior material β and the decorative surface 10, and functions as a waterproof surface.
The deformation is absorbed by the side face 15 so that the deformation cannot be visually recognized. Further, the engaging piece 12 is, as shown in FIG. 3 a sectional view taken along the line EE in FIG.
A part of the insertion surface 11 is formed by punching and bending along the longitudinal direction, or although not shown, the engagement piece 12 is formed by continuously bending along the longitudinal direction of a part of the insertion surface 11. To do.

〔Example〕

Here, regarding the construction method of the corner member α according to the present invention,
A brief description will be given with reference to FIGS. 1 and 2A and 2B. First, a long fixture A as shown in FIG. 2 (a) is attached to a corner portion base C composed of main columns, a waterproof sheet, etc. as shown in FIG. 1 (the waterproof sheet is omitted). Construction from the base to the eaves on the corner base C using a fixture such as a nail. After the installation of the fixture A is completed, the dry exterior material β is placed on the fixing surface 1 of the fixture A and fixed with a fixture such as a nail. After the completion of the construction of the dry exterior material β on the corner portion, the engaging portion 13 of the cover B is attached to the fitting portion 9 of the fixture A
Then, the engaging piece 12 and the fitting piece 8 are engaged with each other by pressing so as to insert the end portion of the dry type exterior material β and the construction of the corner portion is completed.
