Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a retaining edge used to cover the top surfaces of interior and exterior materials and to fit around windows. [Prior Art] As a conventionally used retaining edge, one having a shape as shown in FIG. 1 can be mentioned. In other words, the toe edge 1 is attached to the attachment body A such as the trunk edge or pillar through the nail B.
was fixed, and then the exterior material C was inserted. Moreover, the width l 1 of the fixing piece 2 of the retaining edge ₁ and the width l ₂ of the decorative piece 7 were approximately equal in size, and the receiving piece 8 was formed to have a width of about 2 to 5 mm. [Problems that the invention aims to solve] With this type of toe, the length of the fixing piece and the decorative piece are the same, making it difficult to drive nails, leaving dents or deforming the decorative piece. . = There is a large step between the surface of the building material and the edge, which lacks aesthetic appeal.
= Because the width of the receiving piece is narrow, it is not possible to correct the decorative piece so that it is parallel to the surface of the exterior material. The elasticity of the decorative piece does not act sufficiently between the receiving surface and the surface of the exterior material C, resulting in a gap between the two members. Since the building material is simply inserted into the toe edge, elasticity does not work sufficiently between the receiving piece and the decorative surface of the building material, and moreover, rainwater that has entered from the decorative surface of the building material spreads onto the surface of the fixed piece of the toe edge. 〓When the retaining edges are connected in the middle and used, a large step or gap is created at the connecting part, which spoils the aesthetic appearance. There were other drawbacks. [Means for solving the problem] In order to eliminate such drawbacks, the present invention makes the length of the mounting part protrude by 10 mm or more from the length of the decorative piece to facilitate nail driving, and to prevent the penetration of the nail from penetrating. It allows rainwater to flow down without spreading it, works together with the receiving piece of the decorative piece to hold the building material in place, and also forms the boundary between the surface of the building material and the edge into a smart external shape.
Even when the toe edges are connected in the middle, the present invention proposes a toe edge that is formed to have a small step, improve the aesthetics, and securely hold down the building material. [Example] Hereinafter, an example of the collar according to the present invention will be described in detail with reference to the drawings. Note that parts corresponding to those in FIG. 1 are given the same symbols and numbers. That is, FIG. 2 is a perspective view showing the above-mentioned snap edge 1 , in which a surface-treated steel plate, a PVC steel plate, a stainless steel plate, and an aluminum plate are formed as shown, and the mounting portion 2 and the L-shaped decorative portion 5 are integrated. The cross section as a whole is formed into a U-shape. To explain further, the mounting part 2 has a long shape, and there is at least one part in the middle of the flat plate.
A rib 3 in which one or more types of convex ribs or concave ribs (not shown) of a length larger than a length are formed parallel to the L-shaped decorative portion 5 , a tongue piece 4 provided at the tip thereof, and a mounting portion including the tongue piece 4. The tip is also formed from a notch portion 11 cut out over a predetermined length in the longitudinal direction,
It mainly serves to fix the retaining edge 1 to the mounting body A. In addition, the ribs 3 work together with the L-shaped decorative part 5 to strengthen the clamping force of the building material C, prevent rattling at the end of the exterior material C, and prevent rainwater from leaking into the stopper 1 from the mounting body. A. It also has the function of preventing rain from spreading to the back side of the exterior material C. Further, the tongue piece 4 is formed by bending the lower end edge of the attachment part 2 inward to prevent danger during construction of the retaining edge 1 . Further, the L-shaped decorative part 5 is integrally formed from an end cover piece 6 of the exterior material C, a decorative piece 7, and a receiving piece 8 having an ∠-shaped cross section. The other end corner of the mounting part 2 is bent inward, for example, at an angle of about 90°.
A notch 12 is formed by cutting out a corner of the cover piece 6 side over a predetermined length in the longitudinal direction. Further, the decorative piece 7 is parallel to the mounting part 2 and has a dimension that is at least 10 mm smaller than the width of the mounting part 2 , and the receiving piece 8 has an inclined piece 9 that is inclined inward at an obtuse angle at the tip of the decorative piece 7. , the boundary between the surface of the sheathing material C and the tong edge 1 is made smart, the waving of the tip is prevented, and the sheathing material C is kept in a stable state.
It is formed from a patch 10 so as to be in contact with it and to ensure that a caulking material (not shown) can be planted thereon. A notch 1 cut out over a predetermined length in the longitudinal direction of the backing piece 10 at the tip of the receiving piece 8
3 was formed. The notches 11, 12, and 13 formed in this way are useful when connecting the retaining edge 1 , and to explain the dimensional relationship of the connecting parts as shown in Figs. , which improves aesthetics. Mounting part 2
W ₁ is the dimension from the end cover piece 6 to the rib ₃ , W 2 and W ₃ are the dimensions of the decorative piece 7, W ₄ is the dimension of the receiving piece 10, W ₅ is the dimension of the end cover piece 6 (thickness )
T ₁ is the thickness of the building material C, T ₂ is the thickness of the building material C, and the notch portions 11 to 1
The dimensions (height) of 3 are H ₁ , H ₂ , H ₃ , the width is W ₆ ,
Assuming W ₇ and W ₈ , W ₁ > W ₄ + W ₅ , W ₄ ≧W ₂ ,
W ₃ > W ₄ , W ₁ ≧W ₄ + W ₅ +7mm, W ₆ ≦5mm, W ₇
≦5mm, W ₈ ≦5mm, T ₁ > T ₂ or T ₂ +2~5mm≒
T ₁ , H ₁ = H ₂ = H ₃ , which is about 10 to 50 mm. [Example of construction] Now, it is assumed that the retaining edge 1 shown in FIG. 2 is used and installed as shown in FIG. 3. That is, fix the toe edge 1 to the mounting body A made of a pillar via the nail B, then attach the exterior material C, and when the predetermined length is reached,
The retaining edge 1 is newly connected using the notches 11 to 13, and then the exterior material C is attached in the same manner. [Effects of the invention] As mentioned above, according to the collar according to the present invention,
Since there is a difference of 10 mm or more in width between the mounting part and the L-shaped decorative part, it is easy to drive nails, and the decorative part is not deformed or dented. In addition, the ribs and receiving pieces provided on the attachment part can hold the end of the building material in a stable state without wobbling, and rainwater leaking inside can flow down without spreading. Furthermore, since the receiving piece is formed on an inclined surface, the boundary between the surface of the building material and the toe edge becomes smart, making it possible to form a wall with a beautiful appearance.
In addition, since the notch is formed, when connecting the retaining edges, steps and gaps are suppressed, and the aesthetic appearance is improved.
