Description

[Detailed description of the invention] [Technical field] The present invention engages the ends of one adjacent metal roofing material to one side of the hanger, and the end of the other metal roofing material to the other side of the hanger. The present invention relates to a connection structure for metal roofing materials in which a long waterproof cap is fitted onto the outside so as to straddle both of these engagement points, and in particular, it relates to a technique for improving the sealing performance of the connection portion.

[Background Art] Conventionally, as shown in FIG. 7, the end of one adjacent metal roofing material 11 is engaged with one side of the hanger 3, and the end of the other metal roofing material 11 is engaged with one end of the metal roofing material 11. hanger 3
In order to connect both roofing materials 11, 11 by fitting a long waterproof cap 9 on the other side so as to straddle both of these engagement points, the hanger 3 has a small width and is used for connection. Since it does not exist along the entire length of the part, it is possible to connect with high sealing performance in the places where the hanger 3 is present, but in the places where the hanger 3 is not present, as shown in Figure 8b, There was a problem in that the absence of 3 caused loosening, resulting in a decrease in connection strength and a decrease in sealing performance.

[Purpose of the invention] The present invention was made in consideration of the above points, and its purpose is to increase the connection strength and sealing performance in locations where there are no hangers through rational innovation. Our goal is to provide a connection structure for metal roofing materials that can be used to connect metal roofing materials.

[Disclosure of the invention] The invention is based on one side portion 4 of a hanger 3 that is protruded from a roof base 2 at one end of a roof material body 1 made of a metal plate.
An engaging portion 5 that engages with the other side 6 of the hanger 3 is formed at the other end of the roof material main body 1, and an engaging portion 7 that engages with the other side 6 of the hanger 3 is formed. Abutment pieces 8, 8 are extended upwardly from the tip side of each of the hangers 3, and the engaging portion 5 is engaged with the one side portion 4 of the hanger 3, and the engaging portion of the adjacent roof material body 1 is engaged with the engaging portion 5. 7 is engaged with the other side 6 of the suspender 3, and both abutting pieces 8, 8 are opposed to each other at a location upwardly away from the suspender 3, so that the engaging portion 5 and the engaging portion 7 are connected to each other. A waterproof cap 9 having a generally inverted U-shaped cross section is fitted over these, and vertical pressing pieces 10 formed facing each other at the upper part of the waterproof cap 9 are brought into contact with the outer surface of the abutment piece 8, respectively. The present invention relates to a connection structure for metal roofing materials in which contact pieces 8 are brought into elastic contact with each other, and by configuring it in this way, the above object can be achieved.

Embodiments of the present invention will be described in detail below based on the drawings.

The roofing material 11 is made of a metal plate which has been subjected to rust prevention treatment such as color painting. In the roofing material 11, an engaging part 5 is formed at one end of the roofing material body 1, which can be engaged with one side part 4 of a hanger 3 protruding from the roof base. Roofing material body 1
An engaging portion 7 to be engaged with the other side 6 of the hanger 3 is formed at the other end. The shapes of the engaging portion 5 and the engaging portion 7 can be changed in various ways according to the shape of the hanger 3. Engagement portion 5 and engagement portion 7
Abutment pieces 8 are extended from the distal end portions of each of the two. As shown in FIG. 1, the abutting piece 8 is formed to have an inverted U-shape in cross section, and its free end serves as an elastic abutting piece 12. The proximal end of the abutting piece 8 is bent protrudingly toward the elastic abutting piece 12, and this protruding portion 13
A draining space 14 can be configured in the draining space 14. The hanger 3 is attached to the roof board 15, which is an example of the roof base 2, with nails or tapping screws 16, but the hanger 3 may be integrally formed with the tight frame 17 as shown in FIG. As shown in FIG. 1, the hanger 3 has a substantially U-shaped cross section, and a roughly U-shaped engagement piece 18 is formed outwardly and downwardly on one side 4 and the other side 6 of the hanger 3, respectively. It has been done. As shown in FIG.
The roof material 11 is attached to the shedding board 15 via the hanger 3 by engaging with the roof material 11. Next, the adjacent roof material 11 is engaged with the engagement piece 18 of the hanger 3. In this case, the elastic contact pieces 12, 12 are opposed to each other. Then, by utilizing its elastic deformability, the waterproof cap 9 is applied to the engaging portions 5 and 7 of both roofing materials 11, 11.
It is fitted elastically from above. In such a fitted state, the vertical pressing piece 10 formed on the waterproof cap 9 comes into contact with the outer surface of the abutting piece 8 of the roofing material 11, causing the elastic abutting pieces 12, 12 to come into elastic contact with each other. Let it happen. In this way, hanger 3
Waterproof cap 9 regardless of whether it is present or not.
The abutment pieces 8, 8 are connected to each other by this. In such a connected state, points A, B,
The roofing material 11 contacts the waterproof cap 9 at locations C, D, and E to provide a seal, and a drainage space 14 is also formed to provide a reliable seal. Particularly in the vertical pressing piece 10 portion, a sealing surface that is long in the vertical direction can be constructed, and more effective sealing can be achieved.

The shapes of the hanger 3, the waterproof cap 9, and the roofing material 11 can be changed, that is, the hanger 3 can be integrated into the tight frame 17, or the waterproof cap 9 can be formed into a substantially convex shape, as shown in FIG. Various methods are conceivable, such as forming the roof material 11 into a folded plate roof having peaks and valleys.

[Effects of the invention] In summary, the present invention has both abutment pieces facing each other at a location upwardly away from the hanger, and an engaging part with a substantially inverted U-shaped cross section straddling the engaging parts. The waterproof cap is fitted onto the outside, and the vertical pressing pieces formed facing each other at the upper part of the waterproof cap are brought into contact with the outer surfaces of the abutment pieces, so that the abutment pieces are elastically abutted against each other. In other words, the abutment piece does not touch the suspender but comes into contact with it at a location away from the suspender, so there is no gap caused by the presence or absence of the suspender as in the past, and there is no gap between the connecting parts. It has the advantage that sealing performance can be greatly improved. Moreover, since the distance between the abutting parts is not affected by the suspender, there is no variation in the connection strength between the parts with the suspender and the parts without the suspender, and moreover, the waterproof cap can be attached to the engaging part and the engaging part. Since the vertical pressing piece is fitted externally and brought into contact with the abutting piece, there is an advantage that the connection strength can be increased.
