This is related to the connection structure of.

(Prior art) In metal sheet roofs, which are made by engaging and connecting a plurality of metal roof sheets made of copper plates or the like in the vertical and horizontal directions, the roof is usually covered from the eaves side to the left and right. As they are being placed, they are gradually placed upwards towards the ridge. In this case, the connection between the roof sheets 1 in the left and right direction is made by connecting the engaging portion 2 formed on one side edge of the roof sheet 1 by folding it back toward the upper surface side, and the other side of the roof sheet 1 adjacent to the engaging portion 2. The engagement parts 3 formed by folding the edges downward are engaged with each other, and the connection in the vertical direction is made by connecting the engagement parts 3 formed by folding the edges downward to the upper side. The seam 4 and the lower seam 5 formed by folding the lower edge of the upper roof sheet 1 downward are connected by engaging with each other, as shown in FIG. 4
If the lower edge 5 is formed over the entire length of the roof plate 1, the upper and lower edges of the engaging portions 2 and 3 will also be bent. Moreover, since the engaging portions 2 and 3 are not provided with guides, engagement is not only difficult and requires skill, but also prevents the upper and lower gaps 4 and 5 of the adjacent roof panels 1 and 1 from being formed. If a dimensional error occurs, there is a possibility that engagement may become impossible.

For this purpose, conventionally, as shown in Fig. 5, the upper seam 4 and the lower seam 5 are formed with both ends left open, and both engaging parts 2 and 3 are made straight, and the construction is carried out at the site. After engaging both the engaging portions 2 and 3, the upper and lower edges are bent toward the upper surface and the lower surface, respectively, to form both ends of the upper seam 4 and the lower seam 5. , or as shown in Figure 6, the top 4
is formed by leaving both sides of the edges intact, and the lower edge 5 is formed over the entire length of the roof plate 1, and the lower edge is cut out from the bent part of the lower edge 5 of one of the engaging parts 2 and fitted. forming a fitting groove 6, fitting the upper end edge of the other engaging part 3 through the fitting groove 6, and then sliding it upward;
The engaging portions 2 and 3 are engaged, and then the upper edges thereof are bent toward the upper surface side to form both ends of the upper seam 4.

(Problems to be Solved by the Present Invention) However, in all of the above-mentioned conventional methods, at the construction site where metal roofing sheets are installed, the upper and lower edges of the engaging portion of the metal roofing sheet, or the upper end edge Because it requires the work of bending, it is necessary to prepare the necessary tools for this work, such as a sword blade to hit the bottom of the bend, a clapboard to hit the top of the bend, and a grip to adjust the bend. Therefore, the problem is that not only does the work require training, is troublesome, and takes a long time, but also that care must be taken to ensure that the tools do not fall to the ground during the work. There is,
In addition, there was a problem that not only was there a risk of damage to the roof surface since the metal was struck with a clapboard or the like, but it also caused noise pollution.

(Means for Solving the Problems) Therefore, the present invention has been made to solve the above-mentioned problems, in which an engaging portion 11 is formed on one side edge of the roof plate and is folded back toward the top side. , an engaging part 12 folded back toward the lower surface side is formed on the other side edge, an upper flap 13 folded back toward the upper surface side is formed on the upper edge edge, and a lower edge folded back toward the lower surface side is formed on the lower edge edge. Ze1
A plurality of metal roof plates each having a roof plate 4 formed thereon are disposed in the left-right direction, and the top seam 13 of the lower roof plate and the bottom seam 14 of the upper roof plate are engaged with each other in the vertical direction. In the case of a roof made of metal sheets, which is continuously covered with a roof, there is provided a roof in the vicinity of the upper flap folding point 13a of one of the engaging parts 12 and in the vicinity of the lower flap folding point 14a of the other engaging part 11, respectively. Fitting notches 16 and 15 are formed from the folded tip of the engagement part toward the proximal end of the folded flap, and the engagement part 11 is located at the folded part on the upper flap side.
A notch 11' is formed by cutting out the edge of the folded end in an inclined or arc shape, and when connecting left and right adjacent roof panels, the fitting notch 16 of one roof panel is connected to the fitting notch 16 of the adjacent roof panel. The intended purpose is achieved by fitting into the fitting notch 15 from above and below along the longitudinal direction of the engaging portions, so that the engaging portions can be slidably engaged with each other. be.

(Example) The present invention will be described below with reference to an illustrative example.

An engaging portion 11 folded back toward the upper surface of the roof panel a is formed on one side edge of the roof panel a, and an engaging portion 12 folded back toward the lower surface side of the roof panel a is formed on the other side edge. It is formed. Further, an upper flap 13 is formed on the upper edge of the roof plate a, which is folded back together with the upper edges of the engaging portions 11 and 12 on the upper surface side of the roof plate a, and on the lower edge of the roof plate a. Both engaging portions 11, 12 on the lower surface side of
A lower edge 14 is formed by folding back together with the lower edge of the . Then, the mutually engaging portion of the roof panels a, that is,
Roof plate a is formed at the overlapped part of the plate material formed at the folded part of the main body of the roof plate a and the engaging parts 11 and 12, and the overlapped part of plate material formed at the folded part of the engaged parts 11 and 12 and the upper edge 13, respectively. There is a gap slightly wider than the plate thickness, and an inclined or arcuate notch 11 is provided on the folded end edge side of the engaging portion 11 located at the bent portion on the upper edge 13 side of the engaging portion 11. ' is provided so that, during the work of connecting roof panels, the mutually engaging portions of adjacent roof panels a and a' can be inserted to the end of insertion without interfering with each other. Further, the folding width of the engaging portions 11 and 12 is relatively wide, so that the engaged state after connecting the roof panels is stable and reliable.

Near the upper flap folding point 13a of one engaging part 12 and the lower flap folding point 14a of the other engaging part 11
Fitting notches 16 and 15 are formed in the vicinity of the engaging portions, respectively, in a biting manner from the folded tip of the engagement portion toward the folded proximal end of the flap. Figure 1A
and B, the fitting notch 16 on the upper seam 13 side is formed in a substantially arc shape centered on the upper seam folded back 13a, and the fitting notch 15 on the lower seam 14 side is formed in the engaging portion 11. A notch is shown with a sloping straight cutout extending over the entire width of the cutout.

To connect the aforementioned roof plate a to another adjacent roof plate a', first insert the lower surface side 16'a of the fitting notch 16' of the other roof plate a' into the fitting notch 15. 2, the engaging portion 12' of the roof sheet a' is positioned on the lower surface side of the engaging portion 11 of the roof sheet a. In this state, as shown in FIG.
When a' is slid upward along the longitudinal direction of the engagement part 11, the engagement part 11 of the roof plate a acts as a guide for the engagement part 12' of the roof plate a', so that the engagement part 1
1 and 12' can slide smoothly in the vertical direction without coming apart. Then, at the sliding end, the folded outer peripheral surface of the upper flap 13' side of the roof plate a' side engaging portion 12' comes into contact with the folded inner peripheral surface of the upper flap 13 of the roof plate a side. Thereafter, the roof plate a' is pulled laterally to engage the engaging portions 11 and 12'. As described above, since the present invention adopts the vertical sliding method, once the fitting notches 15 and 16 of adjacent roof panels are fitted together from the vertical direction in an insert-like manner, the engaging portions 11 and 12 Even if the gap is small, it can be slid in the vertical direction while expanding the gap.

In the above embodiment, a linear fitting notch 15 extending over the entire width of the engaging part 11 is formed at the lower edge of the engaging part 11 on the outside at the lower seam folded part.
Although a substantially arc-shaped fitting notch 16 centered on the upper seam folding point 13a is formed on the upper end edge of the engaging portion 12 which is the outer side of the upper seam folding part, the present invention is not limited to this. For example, the fitting notches 16 and 15 may both be formed in an arc shape (see FIGS. 9A and 9B), or may be formed in a straight line shape (see FIGS. 11A and 11B). In short, the shape of the fitting notches 16, 15 can be freely selected as long as the fitting notches 16, 15 can be fitted into each other from above and below in an insert-like manner, as long as it does not go against the gist of the present invention. can.
Furthermore, the folded widths of the engaging portions 11, 12' may be formed so as to become narrower from the insertion start end to the insertion end (see FIGS. 7 and 8).
