Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an exterior metal plate used for a corner part, and more specifically, the present invention relates to an exterior metal plate used for a corner part, and more specifically, a method that prevents deformation of the exterior material body when nailing into the exterior material body. This invention relates to a technique for effectively utilizing the above structure to increase overall strength and appearance, and for preventing cracking or chipping of ceramic exterior materials, for example, where exterior metal plates are attached by nailing.

[Background Art] Conventionally, as shown in FIG. 5, an exterior metal plate A' for a corner used for a corner portion is made by pasting ceramic-based exterior materials 7, 7 on the outer surface of a column 5 with felts 6 interposed therebetween. , which is fixed by driving a nail into the corner part in the nailing hole 3, and in such a case,
The exterior metal plate A′ for corners is easily deformed,
In addition, the nails are conspicuous and the appearance is easily deteriorated, the strength of the exterior metal plate A' itself is weak, and there are further problems such as the ceramic exterior material 7 being cracked or chipped when nailed.

[Purpose of the invention] The present invention was made in view of the above problems, and its purpose is to prevent deformation of the exterior material body when nailing into the exterior material body, and to To provide an exterior metal plate for a corner, which enhances the overall strength and appearance by effectively utilizing the above configuration, and prevents cracking or chipping of, for example, a ceramic exterior material to which the exterior metal plate is attached by nailing.

[Disclosure of the invention] The exterior metal plate for corners of the present invention has diagonal rib pieces 2 bent toward the outside and inward on both side edges of the exterior material body 1 having an L-shaped cross section. The nailing hole 3 to be formed is formed into a countersunk shape, and the height a of the dish-shaped rib piece 4 of the nailing hole 3 to be formed into the countersunk shape is made approximately equal to the height b of the diagonal rib piece 2. By configuring it in this way, the above object is achieved. In other words, the diagonal rib pieces 2 are formed on both side edges of the exterior material body 1 so as to face toward the outside and inward, and the nailing holes 3 formed in the exterior material body 1 are formed in the shape of a countersunk hole. The strength of the exterior material main body 1 can be greatly increased by the plate-shaped rib pieces 4 of the nailing holes 3, and the height a of the plate-shaped rib pieces 4 can be made smaller than the height b of the diagonal rib pieces 2. By making it approximately equal to , it is possible to prevent the countersunk hole shape 4 and the diagonal rib piece 2 from receiving the impact applied to the exterior material body 1 at the end of nailing, thereby preventing the exterior material body 1 from being deformed. Even when nailing the exterior material body 1 to the ceramic exterior material 7, damage to the exterior material 7 can be avoided,
In addition, although the nail 8 is placed in the countersunk nailing hole 3 and the countersunk rib piece 4 is provided, there is a height b on the side edge of the exterior material main body 1 that is equal to the height a of the countersunk rib piece 4. Because of the diagonal rib pieces 2, it is possible to improve the fit and enhance the appearance.

Embodiments of the present invention will be described in detail below based on the drawings. The exterior material main body 1 is formed to have an L-shaped cross section, and diagonal rib pieces 2 are bent on both side edges of the exterior material main body 1 so that the outer side extends inward. A nailing hole 3 formed in the exterior material main body 1 is formed in a countersunk shape. The height a of the dish-shaped rib piece 4 of the nailing hole 3 to be made into a countersunk-hole shape is made approximately equal to the height b of the diagonal rib piece 2.

According to such a structure, as shown in FIG. 1, ceramic-based exterior materials 7, 7 are applied to the outer surface of the pillar 5 through felt 6, and nails 8 are attached to the corner portions in the nailing holes 3. The exterior metal plate A for the corner is driven in and fixed, and in this case, the exterior material body 1
A diagonal rib piece 2 is formed on both side edges of the slanted rib piece 2 toward the outside and inward, and a nailing hole 3 formed in the exterior material body 1 is formed in a countersunk shape. The strength of the exterior material main body 1 is increased by the dish-shaped rib piece 4,
By making the height a of the dish-shaped rib piece 4 approximately equal to the height b of the diagonal rib piece 2, the shock applied to the exterior material body 1 at the end of nailing is absorbed by the dish-shaped rib piece 4 and the diagonal rib piece 2. This prevents deformation of the exterior material body 1, and also avoids damage to the exterior material 7 even when the exterior material body 1 is nailed to the ceramic exterior material 7. Then, the nail 8 is placed in the countersink-shaped nailing hole 3, and even though the dish-shaped rib piece 4 is provided, a height b equal to the height a of the dish-shaped rib piece 4 is attached to the side edge of the exterior material main body 1. The presence of the diagonal rib pieces 2 improves the fit and enhances the appearance.

[Effects of the invention] In summary, the present invention has diagonal rib pieces formed on both side edges of the exterior material body so that the outward direction points inward, and the nailing holes formed in the exterior material body are formed in a countersunk shape. The strength of the exterior material body can be greatly increased by using the dish-shaped rib pieces of the nailing holes, which are shaped like countersunk holes.Moreover, the height of the dish-shaped rib pieces is approximately the same as the height of the diagonal rib pieces. Because they are made equal, the plate-shaped rib pieces and diagonal rib pieces receive the impact that is applied to the exterior material body when nailing is completed, preventing deformation of the exterior material body. When nailing the exterior material body, damage to the exterior material can be avoided, and the nails can be placed in the countersink-shaped nailing holes, and even if a dish-shaped rib piece is provided, the side edge of the exterior material body can be avoided. Since the diagonal rib piece has the same height as the plate-like rib piece, it has the advantage that it fits better and can enhance the appearance.
