Description

[Detailed explanation of the idea] This idea relates to a metal roof plate that is stepped in the shape of a single letter.

Conventional roof panels of this type have been connected by planar overlapping or welded connections, resulting in unevenness between the left and right roof panels, and the construction is time-consuming.

In addition, the upper and lower roof panels often engage at the bent edges of the upper and lower roof panels, requiring a large amount of machining on the cross section.

Furthermore, there are drawbacks such as the fact that it is easy to come off due to the worker's walking during roofing, and that even when fixing with hangers, cash work is involved.

Therefore, this idea was developed in order to improve the above-mentioned drawbacks.The metal roofing plates to be roofed in tiers are firmly fixed in the vertical and horizontal directions using hangers that can be easily fixed. is an economical metal that has excellent strength and watertightness, and requires less machining, by using a sealing material and using drainage plates for the left and right connections to strengthen the waterproof function and prevent water leakage. It provides roof shingles.

To explain the bark based on an example, the metal roofing board of this invention shown in Fig. 1 is stepped in a single character shape to constitute a metal roofing board as shown in Fig. 2, and a rectangular metal roofing board is constructed. The upper edge of the main body 1 is formed by bending the upper edge of the substrate 5 upward at a right angle, and then bending the tip end at a right angle from a predetermined height toward the lower edge in a U-shape to a predetermined width to form a bent edge 6. The part is folded by bending the lower edge parallel to the upper bent edge 6 downward at right angles to a predetermined height, and then folding the tip part inward from a predetermined position at a predetermined angle to a predetermined width. A curved edge 7 is formed, and a predetermined notch 8 is provided at a predetermined position in the center in the longitudinal direction of this bent edge 7 as an escape for intersecting the left and right connecting portions, and the left side edge is bent upward at a right angle from the substrate 5. , bent horizontally inward at a predetermined height, and vertically bent downward from a predetermined width position to form a C-shaped bent edge 9, and the right edge is connected to the left edge bent edge 9 on the side edge. Bent edge 10 for fitting
It protrudes, and an apron-like hanging piece 11 is integrated at the lower edge.

That is, the right side edge is bent upward from the substrate 5 at a right angle to a predetermined height, then horizontally bent outward, and the tip is bent vertically downward from a position of a predetermined width to form a bent edge as shown in FIG. A bent edge 10 is formed in a shape that encloses 9.

The contact portions between the apron-like hanging piece 11 and the bent edges 10 and 7 are integrated by welding, and the upper edges of the left and right bent edges 9° 10 are in contact with the left and right side edges of the bent edges 6. The parts are also welded together to prevent water leakage.

To explain the state in which the metal roofing board main body 1 configured in this way is layered in a single character shape, the connection engagement of the upper and lower edges is as follows.
As shown in FIG. 6, the bent edge 6 of the upper edge is pressed down by the convex bent edge 12 of the hanger 2 (FIG. 8) fixed to the shaped steel rafter, and the metal roof board main body 1 is Fix it in the top, bottom, left and right directions by its upper edge.

A bent edge 13 is formed at the tip of the bent edge 12 of the hanger 2 and is bent upward at a predetermined angle so that the tip of the bent edge 7 of the lower edge part is caught.

On the other hand, as shown in FIG. 9, in places where there is no hanger 2, in order to strengthen the engagement between the upper and lower roof panels, the rear part of the saddle-shaped detachment prevention piece 3 of the horse harness shown in FIG. is fixed inside the bent edge 6.

The detachment prevention piece 3 is formed in an engaging portion 14 cut out at a predetermined angle in the front portion so that the bent edges 7 engage the lower portions of the left and right side plates.

As shown in FIG. 4, the left and right side edges are connected so that the bent edge 9 of the left side edge is wrapped around the bent edge 10 of the right side edge, and the metal parts connected to the left and right sides are Since the left and right bent edges 6 of the roof board body 1 are wrapped around each other by the bent edges 15 of the drainage waste board 4, and the bottom plate 16 covers the bottom surfaces of the left and right substrates 5 with a predetermined width, the horizontal direction The bottom plate 16 acts as a gutter for rainwater that enters from the left and right joints due to air flow or water leakage due to capillary phenomenon, and as shown in FIG. Since it is attached so as to protrude from the bent edge 6, the intruding water will not be absorbed by the bottom plate 1.
6 flows out onto the substrate 5 of the lower metal roof plate main body 1 and is drained to the outside.

After completing the installation of the first stage in this way, next align the left and right connecting parts and the notch 8 provided in the bent edge 7 to the upper stage.
A bent edge 13 in which the tip of the bent edge 7 at the lower edge is the tip of the hanger 2, and an engaging portion 14 in the front of the detachment prevention piece 3.
, and pull the metal roof board body 1 upward, and similarly secure the bent edge 6 of the upper edge part with the hanger 2,
The left and right connections are made in the same way, and these steps are repeated one after another to construct a single-character-shaped stepped roof.

In detail, the hanger 2 shown in FIG. 8 has engagement grooves 18 formed at both ends of a fixed plate 17, and a plurality of selected bolt holes formed in predetermined positions of the fixed plate 17.

To attach the hanger 2, as shown in FIG.
In this state, the hook bolt 19 is inserted into the selected bolt hole, the hook 20 is engaged with a vertical part such as an angle, and the bolt is tightened and fixed with a nut.

Note that an elastic seal 21 is attached to the upper part of the bent edge 6 of the upper and lower connecting portions of the metal roof plate main body 1.

With the structure described above, even if water intrudes due to blowing or leaks due to capillary phenomenon at the joint between the left and right side edges, water can be drained to the outside by the drain plate 4, thereby preventing water from entering. At the connection between the upper and lower edges, an elastic seal 21 is attached to the upper part of the bent edge 6.
This makes close contact with the back surface of the substrate 5 to improve watertightness, and furthermore, the space 22 formed by the bent edge 6 and the bent edge 7 is
Since it has a sufficient amount of water, it can completely prevent water from blowing in by wind and rain or water leakage due to capillary phenomenon, and the shape of each bent edge is simple, so it is easy to form and process, and the hanger 2 is easy to install and fix. It doesn't take much time.

Furthermore, in the area without the hanger 2, the tip of the upper folded edge 7 is fixed to the lower folded edge 6 via the detachment prevention piece 3, so that the engagement of the upper and lower roof panels is reduced by 8 times. for a strong connection.

As described above, this invention has made it possible to provide an economical metal roofing board for single-character stepped roofing that can fully perform the functions required of the roofing board.

It is also possible to provide a metal roof plate that prevents dew condensation and has a high heat retention effect by applying a heat insulating material to the space 23 formed on the back surface of the substrate 5.
