This edge A covers the end of the wall material D with the U-shaped portion α. However, with such a toe edge A, it is necessary to insert the end of the wall material D into the U-shaped part α, and when constructing wall material D from the foundation, the toe edge is fixed in advance and the U-shaped part α is inserted. The opening of the portion α had to be pried open by elastic deformation and the wall material D had to be inserted, which resulted in the drawback that strain was applied to the retaining edge A and it deformed. In addition, the nailing portion r must be formed longer than the decorative piece β, and the nails must be driven outward from the decorative piece β, resulting in the disadvantage that the width of the rim must be increased.

Furthermore, when driving a nail with a hammer or the like, there is a drawback in that the decorative piece β is erroneously dented or damaged. Moreover, as shown in Figure 8b, when this kind of retaining edge A is used for a wall material D having an inclined decorative surface such as an overlay, the decorative piece β of the retaining edge A and the wall material D Voids were formed in the decorative surface area, resulting in a lack of design and waterproofness.

[Purpose of invention]

In order to eliminate such drawbacks, the present invention has a decorative cap formed into an L-shaped cross section from a decorative surface part and an insertion part, and a locking cap formed into an L-shaped cross section by a nail driving part and a locking part. It is a locking edge that is composed of two parts, the decorative cap and the locking body, and forms a U-shaped cross section by combining the decorative cap and the locking body.After the locking body is fixed, the wall material is installed, and then the wall material is installed. After that, by inserting the decorative cap into the locking part of the locking body, installation is facilitated, and the insertion part of the decorative cap is provided with an engaging protrusion, and the locking part of the locking body is provided with an engaging protrusion. is provided with a locking groove having a U-shaped cross section, and furthermore, a locking protrusion for locking the engaging protrusion of the decorative cap is formed in the locking groove to strengthen the engagement force between the decorative cap and the locking body,

[Effect of idea]

As mentioned above, the locking edge according to the present invention is composed of two members: the locking body that is fixed to the wall base, and the decorative cap that covers the end of the wall material, making it easy to drive nails. Therefore, the driving position of a fixing tool such as a nail can be determined regardless of the width of the decorative surface portion of the decorative cap, so there is no need to particularly widen the width of the rim or the like. Furthermore, since the decorative cap is attached after fixing the locking body and the wall material, the wall material and the decorative cap do not rub against each other, and the surface of the wall material is not damaged. Moreover, since the cosmetic cap can be attached by simply inserting it into the locking body, it has the characteristic that it does not cause dents or deformation. Furthermore, since the decorative cap is in full contact with the decorative surface of the drywall material having the inclined decorative surface, waterproofness and design are improved. Moreover,
The short decorative cap has an engaging force strengthened by the engagement between the engaging protrusion and the locking protrusion, and is securely attached without slipping downward due to friction with the inclined decorative surface part of the wall material. I can do it. Furthermore, since there is no need to insert the wall material into the retaining edge, it is easy to measure the dimensions of the wall material and facilitate construction. It has the following effects and characteristics.
