Description

[Detailed description of the invention] [Industrial application field] The present invention covers the end surface of drywall materials (hereinafter simply referred to as wall materials) used as interior and exterior materials.
Concerning the fittings around windows and the toe edges used for the base. More specifically, the present invention relates to a retaining edge that can be used for wall materials of different thicknesses.

[Conventional technology]

An example of a conventionally used tong edge A is the one disclosed in Japanese Utility Model Application Publication No. 59-12349, which is made of a colored steel plate, galvanized iron plate, synthetic resin plate, etc., and formed into an approximately U-shape as shown in Fig. 5. It will be done. That is, the end portion of the wall material B is covered by the portion α formed in a substantially U-shape. However, such a edge A can only accommodate one type of thickness, and the wall material B
If the thickness of the wall material B is different, it is necessary to prepare a separate snap edge A corresponding to the wall material B.

[Purpose of invention]

In order to eliminate such drawbacks, the present invention has a horizontal nail driving part, a rising part with the tip of the nail driving part formed almost vertically inward, and a rising part with the tip of the rising part inward. It consists of a decorative surface part bent almost parallel to the decorative surface part, and a stop part part formed in steps with the tip of the decorative surface part bent inward to provide a stopper part that can be used for multiple wall materials. It is something to do.

[Structure of the idea]

An embodiment of a typical snap edge according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a typical embodiment of the snap edge A according to the present invention, in which a long metal plate (color steel plate, aluminum plate, PVC steel plate, stainless steel plate, etc.), a synthetic resin plate, etc. A stopper part 4 is formed by forming the nail driving part 1, the rising part 2, and the decorative surface part 3 into a substantially U-shaped cross section by roll forming, extrusion molding, etc., and by bending the tip of the decorative surface part 3 inward. It is composed of To explain in more detail, the nail driving part 1 is a part where the toe edge A is fixed to the wall base using fixing tools such as nails, and the edge has a seam-like part for waterproofing and to prevent injury during work. A tongue piece 1a is formed. The decorative surface part 3 consists of a decorative piece 3a with the tip of the rising part 2 bent almost parallel to the nail driving part 1, and a side wall decorative piece 3b with the tip of the decorative piece 3a bent, and covers the end of the wall material B. This improves design, waterproofness, and workability. Further, the stopper portion 4 has a waterproof surface 5.
and the guide surface 6 is formed in a step-like manner,
3 by waterproof pieces 5a to 5c and guide pieces 6a to 6c.
It is formed in steps so that it can accommodate three types of wall material B thickness. Furthermore, when the guide surface 6 is pressed by the wall material B, the waterproof surface 5 comes into surface contact with the decorative surface of the wall material B to improve waterproofness and is fixed to the wall base. It functions as a pressing surface for the end portion of B and a waterproof surface.

Here, the dimensional relationship of each part will be briefly explained using FIGS. 1 and 2. The width of the nailing part 1 is W,
The width of the decorative surface part 3 is _W1 , the length of the toe edge A is L, the length from the surface of the nail driving part 1 to the waterproof pieces 5a to 5c is respectively _t1 to _t3 , and the height of the waterproof pieces 5a to 5c. are respectively h ₁ to _{h 3} and the thickness of wall material B is T ₁ to T ₃ , then L≒
Long body of about 2424 to 3636 mm, W≒W ₁ +10 to 50 mm,
t ₁ ≒ T ₁ , t ₂ ≒ T ₂ , t ₃ ≒ T ₃ , h ₁ , h ₂ , h ₃ are 5 to 10 mm
It is the rank.

〔Example〕

Next, a construction example will be briefly explained using FIG. 2. Therefore, as the wall material B, a material with a thickness T ₂ corresponding to t ₂ of the tonging edge A is used. First, the main pillar, the rim,
The nailing part 1 of the toe edge A is fixed via the nail D to the part of the wall base C made of a waterproof sheet or the like (the waterproof sheet is omitted in the figure) where the toe edge A is to be used.
Next, the wall material B is sequentially inserted and connected between the waterproof pieces 5b between the tongs A and the guide pieces 6b to cover the ends of the wall material B as shown in the figure. Note that this is not necessary when using wall material B with a thickness of T ₁ , but when the thickness is less than that, T ₂ or T ₃ , the decorative surface, waterproof surface 5, and guide surface of wall material B are used. A caulking material 7 is planted in the space surrounded by 6, and the caulking material 7 is a hot melt adhesive (2 to 5
(including foamed foam), rubber-based or synthetic resin-based packing materials pasted with adhesive, or swellable water-absorbing resins.

[Other Examples]

What has been described above is only one embodiment of the retaining edge A according to the present invention, and it can also be formed as shown in FIGS. 3 a-x and 4 a-g. In other words, in FIG. 3, a and b indicate a toe edge formed on the nail driving portion 1 by one or more grooves 1b or ridges 1c, or by a combination of grooves 1b and ridges 1c. Figures A and c show a tog edge A in which the tongue piece 1a is formed in the shape of an upward flap, d figure shows a tog edge A with the tongue piece 1a bent in the middle of the nail driving part 1, and figure e shows a tog edge in which the tongue piece 1a is bent upward. In Figures A and F, the tongue piece 1a is triangular, or semicircular or square (not shown), and in Figures A and G, one or more grooves 3c (not shown) are formed on the decorative surface portion 3 . Figures A and h show toe edges A with protrusions 3d formed on the decorative surface portion 3. Figures i and j are toe edges A and k with side wall decorative pieces 3b formed vertically, semicircularly, or at an acute angle (not shown).
