Description

[Detailed description of the invention] (Field of industrial application) The invention relates to a sheet roofing material in which the edges of metal sheets of a certain length are connected in the width direction of the roof. .

(Prior Art) Conventional sheet roofing materials are constructed by connecting the edges of both sides of a certain length of metal plates, such as copper plates, in the width direction of the roof. Those with a ribbed structure that is simply bent in the direction,
Alternatively, the sheet roofing material itself is not bent, and grooves into which the edges on both sides of the sheet roofing material are inserted are integrally formed, and joint waste boards are used in which both ends are fitted into the grooves. .

(Problems that the invention aims to solve) Among conventional roofing board materials, both those with a lattice structure and those that use jointed waste boards require careful construction to prevent rain leaks, making roofing work time-consuming. There is a flaw.

(Means for Solving the Problems) The present invention aims to eliminate the above-mentioned defects, and the purpose of this invention is to connect the longitudinal edges of metal plates of a certain length in the width direction of the roof. In roofing, a vertical groove is formed by sequentially bending one groove wall, the groove bottom, and the other groove wall at one edge in the length direction of the metal plate, and a vertical groove is formed at the top end of the vertical groove. In addition to providing a water stop weir by bending, a folded piece within the depth of the vertical groove is formed on the other edge, and a folded piece on the other edge of the adjacent metal plate is formed within the depth of the groove. The structure is such that the roofing is connected by fitting into the groove below the water stop weir, and even if vertical grooves or joints occur between the metal plates connected in the width direction of the roof, the vertical grooves will not be removed. Alternatively, a roofing system can be constructed in which rainwater leaking from the joints is caught in vertical grooves that are integrated with the planks, and instead of being caused to flow back upwards through a water stop weir, it is allowed to flow into the vertical grooves below through a water stop weir made of metal sheets installed below. , it is possible to provide a plate roofing material that can be easily constructed.

(Embodiment) To explain one embodiment of the present invention, a metal plate 1 is made of a horizontally long rectangular copper plate, and as shown in FIG. The plane surrounded by the edge 4 and the lower edge 5 is the main roofing margin, and straight cuts are made above and below the right edge 2 and the left edge 3, respectively. Drop line 6, 7,
8 and 9 are provided, and one groove wall 11 is provided on the right side of the edge 2.
Protrude the forming pieces such as the groove bottom 12 and the other groove wall 13,
A component piece of the water stop weir 17 whose broken line is indicated by a dashed line is continuously formed on the upper part of each of the forming pieces of the groove wall 11, the groove bottom 12, and the groove wall 13, and the water stop weir 17 is formed at the top end of the component piece of the groove bottom 12. 17 is provided with a continuous outer bent piece 17' forming piece. Further, a tongue-like piece 17a extending downward from the groove bottom 12 is formed. A component piece such as a folding piece 18 is protruded from the left side of the edge 3, a component piece forming an upper joint bend 20 is protruded from the upper edge 4, and a lower joint bend 22 etc. is protruded from the lower edge 5. Protrude the component piece.

From the edge 2 on the right side of the metal plate material 1 in FIG.
The horizontal receiving piece 14 and reinforcing piece 15 are bent from the upper edge slightly lower than the plane of the metal plate material 1. (4th
figure). The groove walls 11 and 13 each have an inclined shape (FIG. 9) that slightly widens downward in a symmetrical manner, and together with the groove bottom 12 form a vertical groove 16. A water stop weir 17 is placed at the upper end of the vertical groove 16 at the third point from the broken line shown in FIG.
Fold it up and set it up as shown in Figures 4 and 8. A tongue-like piece 17a is made to protrude from the lower end of the vertical groove 16.

A vertical groove 1 is formed from the edge 3 on the left side of the metal plate 1 in Figure 1.
A folding piece 18 having a length within a depth of 6 and folded at an inclined angle that closely contacts the right groove wall 13 from the inner surface is provided, and a reinforcing piece 19 is folded back from the edge thereof. (Figure 5).

An upper joint bend 20 is formed from the upper edge 4 of the metal plate material 1 in FIG.

A lower joint bend 22 is formed from the lower edge 5 of the metal plate 1 in FIG. Fold it back and set it up. (Figure 8).

The plate roofing material of this embodiment uses a narrow stopper plate 26 whose tip is bent into an acute angle to form a hook 27 shown in FIG. Hook 27 is hooked onto piece 20 as shown in FIG. 8, and fixing plate 26 is fixed to roof a by nailing. 27, put the upper joint piece 20 on top of the piece 27, and attach the piece 20 and the hook 2.
7 is placed on the underside of the metal plate material 1 and roofing is done one after another.

In addition, the metal plate material 1 adjacent to the right side is attached to the receiving piece 14.
Stack the folded pieces 18 on top of each other and insert the folded pieces 18 into the cutoff weir 17 of the vertical groove 16.
9, and the piece 18 is brought into close contact with the inner surface of the groove wall 13, as shown in FIG.

As a result of this roofing, the vertical grooves 16 are continuous in the vertical direction as shown in FIG. 7, and each vertical groove 16 is prevented from backflowing with rainwater by a water stop weir 17 at the upper end. Vertical groove 1
The lower end of the pipe 6 passes over the lower water stop weir 17 as shown in Figures 7 and 8, so there is no water leakage.

The tongue-shaped piece 17a is bent and reinforced on the lower surface of the vertical groove 16.

If you do not want the longitudinal grooves 16 to appear on the surface,
- As shown in Figure 12, the width of the groove bottom 12 is narrowed, and during roofing work, the left edge 3 of the metal plate 1 adjacent to the right is brought into contact with the right edge 2 of the metal plate 1 adjacent to the left. After forming a seam b, the folded-down piece 18 is inserted into the inside like the vertical groove 16.

The vertical grooves 16 or seams b can be roofed in a staggered manner.

(Operations and Effects of the Invention) As clarified by the explanation of the above embodiments, the present invention provides a vertical groove formed by bending a water stop weir at the upper end on one edge of the metal plate in the length direction. , by providing a folded piece on the other longitudinal edge within the depth of the vertical groove, it prevents rainwater from flowing back upward in the direction of the slope of the roof, and it also looks like a vertical groove or a roof. This has the effect of making it possible to easily and quickly apply roofing in which the joints formed by joining metal plates in the width direction are continuous in the vertical direction or arranged in a staggered manner.
