[0012]

The prior art 1 and the prior art 2 have the following problems. [A. The rainwater on the roof plate (1) easily flows into the skirts (112) (212), so when rainy wind is strong, the rainwater flows from the connection between the roof plates (1) (1) to the roof of the building (23). There is a risk of rain leaks into the wall (24). ]

When strong rainstorms or typhoons blow strongly, part of the rainwater flowing on the roof plate (1) is vigorously pushed by the strong wind, and the skirts (112) (212) of the cap (3) are pushed.
It is pushed in and the water-blocking recess (1) of the side plate (10) of the cap (3)
1) and the rising connection edge (4) of the roof plate (1) are fitted tightly to the water-blocking ridges (6). Passes upward between the contact surfaces, then flows down in the cap (3), and both right and left upward connection is achieved. There is a possibility that rain may leak from the roof walls (24) of the building (23) into the building (23) through the facing surfaces of the edges (4) and (4).

[B. Negative pressure caused by strong wind
(1) may be peeled off from the roof wall (24) of the building (23). When a strong wind such as a storm or a typhoon blows, the negative pressure caused by the wind may suck up the roof plate (1) and lift it up, and the roof plate (1) may be peeled off from the roof wall (24) of the building (23).

[C. Since the cap (3) is only fitted and fixed to the roof plate (1), its fitting and fixing force is relatively weak, and the cap (3) is disturbed by the roof plate (1) and the sling (2). There is a risk of coming off. ] The cap (3) is fitted and fixed to the roof plate (1) only at the place where the water-impervious recess (11) and the water-impermeable ridge (6) are fitted together. Weak force, cap (3) is shingles
There is a risk that it will come off from (1) and the suspender (2) due to disturbance force.

[D. When an operator puts the cap (3) on the ascending upward coupling edges (4) (4) and the hanger (2), the left and right skirts (112) (112) (212) of the cap (3) ( twenty one
2) As much as the operation to pry open this cap is necessary
The assembly work of (3) is complicated and takes time. ]

Compatible left and right roof boards (1) (1)
(4) After the (4) is connected and fixed to the roof wall (24) of the building (23) by the hangings (2), the cap (3) is compatible and the rising connection edge (4) (4) and the hangings (2) ) And assemble. Left and right skirts of the cap (3) (112) (112) (212) (212) both lower edges (113) (11
3) The width between (213) and (213) is narrower than the width between the compatible upward connecting edges (4) and (4) and the entire width of the suspension (2). Therefore, when the worker puts the cap (3) on the compatible upward connecting edges (4) (4) and the hanger (2), the left and right skirts (112) (112) (of the cap (3) (112) ( The work of assembling the cap (3) becomes complicated and time-consuming because the operation of prying open the 212) and (212) is required.

An object of the present invention is to do the following. (A). Prevents rainwater on the roof plate from flowing into the skirt of the cap and stalls in the skirt to prevent rainwater from leaking from the joint between the roof plates into the roof wall of the building even when the wind is strong. Is strongly prevented. (B). By pressing the roof plate at the lower edge of the skirt, the roof plate is strongly prevented from being peeled off from the roof wall of the building due to the negative pressure caused by the strong wind.

(C). By tightly fitting and fixing the cap to the roof plate and the hanger, the cap is prevented from coming off from the roof plate and the hanger due to a disturbance force. (D). By tightly fitting and fixing the cap to the roof plate and the hanger, the lower edge of the cap skirt strengthens the force that presses the roof plate, so that the negative pressure generated by the strong wind causes the roof plate to move from the roof wall of the building. It is more strongly prevented from being peeled off.

(E). By making the cap less susceptible to plastic deformation, the fitting surface pressure between the water-blocking concave line of the cap and the water-blocking convex line of the rising connection edge of the roof plate is maintained with high accuracy, and the space between these mating faces is blocked. Maintains high water performance.

(F). It prevents the rainwater on the roof plate from freely flowing into the skirt of the cap, and by stalling and dropping the inflowing rainwater in the wide buffer space inside the skirt, the rainwater will not be able to flow between the roof plates even when the wind is strong. Prevents rain from leaking into the building's roof wall from the joints. (G). Dust that has accumulated in the buffer space and the rainwater absorbed by the roof are used to wash away the dust that has accumulated in the buffer space inside the skirt of the cap with the rainwater flowing over the roof plate. Eliminates the corrosion of the board.

[0029]

EFFECTS OF THE INVENTION The connecting structure between vertically-roofed metal roof plates of the present invention has the following effects. ○ Invention 1. Claim 1. See FIG. 1 to FIG. 5 or FIG. [A. Rainwater on the roof plate (1) is less likely to flow into the skirt (12) and also has a large buffer space (1) inside the skirt (12).
Because it stalls and falls at 4), rainwater flows from the connection between the roof plates (1) (1) to the roof wall (2) of the building (23) even when the wind is strong.
4) Strongly prevent leaking into the interior. ]

When strong rainstorms or typhoons blow, a part of the rainwater flowing on the roof plate (1) is vigorously pushed by the strong wind and pushed into the skirt (12) of the cap (3), Passing upward between the contact surfaces of the cap (3), which fits tightly between the watertight ridges (11) on the side plate (10) and the watertight ridges (6) on the rising connection edge (4) of the roof plate (1). Then, it flows down in the cap (3) and passes between the facing surfaces of the left and right compatible upward connecting edges (4) and (4),
A rain leak may occur from the roof wall (24) of the building (23) invading the building (23).

According to the first aspect of the present invention, rainwater on the roof plate (1) which is about to be pushed into the skirt (12) by a strong wind does not flow into the skirt (1).
Since the lower edge (13) of 2) is in contact with the roof plate (1), most of the rainwater can be prevented from flowing into the skirt (12) from between the contact surfaces. A small portion of that rainwater is a skirt (1
Even if it penetrates into the inside of 2), the force of the flow of the invading water is rapidly weakened due to the rapid spread from the contact surface to the wide buffer space (14). This weakened invading water is
It collides with the rising connection edge (4) from (1) and is easily bounced off, smoothly falling in the wide buffer space (14), and between the abutment surfaces of the skirt lower edge (13) and the roof plate (1). Smoothly flows from the outside.

As a result, the invading water in the buffer space (14) almost never passes upward between the contact surfaces of the water-blocking ridges (6) and the water-blocking ridges (11), which prevents rainwater and wind. Even when strong
It is possible to strongly prevent rainwater from leaking into the roof wall (24) of the building (23) from the connecting portion between the roof plates (1) (1).

[B. Since the lower edge (13) of the skirt (12) presses against the roof plate (1), the roof plate (1) is torn off from the roof wall (24) of the building (23) due to the negative pressure caused by the strong wind. , Prevent strongly. ] When a strong wind such as a storm or a typhoon blows strongly, the negative pressure caused by the wind sucks up the roof plate (1), and the building (23)
Is about to be stripped from the roof wall (24) of the. In the present invention 1, since the lower end edge (13) of the skirt (12) presses the roof plate (1), the roof plate (1) is fixed to the building (23) by the negative pressure generated by the strong wind.
It can be strongly prevented from being peeled off from the roof wall (24) of the.

[C. The cap (3) is fitted and fixed in two steps to the roof plate (1) and the hanger (2),
The cap (3) is replaced by the roof plate because its fitting and fixing force is doubled.
Strongly prevent it from coming off from (1) and the suspender (2) by a disturbance force. ] The cap (3) is fitted to the roof plate (1) and the hanger (2) at the position where the water-impervious recessed line (11) and the water-impermeable line (6) are fitted, and the removal-preventing line (19). Since the fitting fixing force is doubled at the fitting position between the and the retaining strip (18), the fitting fixing force doubles.
It is possible to strongly prevent the cap (3) from coming off the roof plate (1) and the hanger (2) by a disturbance force.

[D. The lower edge (13) of the skirt (12) of the cap (3) has a stronger force to press the roof plate (1), and the negative pressure generated by the strong wind causes the roof plate (1) to move to the roof wall (24) of the building (23). ) Is more strongly prevented from being peeled off. ] As described in the above effect [C], the cap (3) is the roof plate.
Since it is strongly fixed to the (1) and the hanger (2) in two steps, it is strongly prevented from coming off due to disturbance force, so the lower end of the skirt (12) of the cap (3) The roof (13)
It is possible to more strongly prevent the roof plate (1) from being peeled off from the roof wall (24) of the building (23) by the negative pressure generated by the strong wind because the force pressing the (1) becomes stronger.

Invention 2. Claim 2. See FIG. This invention 2 has the effects [A], [B], and
In addition to [C] and [D], the following effects are exhibited. [E. Since the large-diameter circular arc ridge (20) is unlikely to be plastically deformed and the elastic restoring force is stable, the fitting surface pressure between the water-impervious concave line (11) and the water-impermeable ridge (6) is maintained with high accuracy. High water impermeability is maintained between the mating surfaces, and rainwater passes between these mating surfaces and the building (2
It is possible to more strongly prevent rain from leaking into the roof wall (24) of 3). ]

When assembling the cap (3) by covering both the left and right roof plates (1) and (1) on the upward connecting edges (4) and (4) and the hanger (2), the cap (3) The skirt (12) of the cap (3) and the side plate (10) when the water-blocking recess (11) rides on the water-blocking ridge (6) of the rising connecting edge (4) and then fits.
Are pushed outward to the left and right, and the large-diameter circular arc ridges (20) elastically deform.

The large-diameter circular arc ridge (20) expands the maximum elastic deformation dimension of the left and right side plates (10) (10) with respect to the top plate (9) of the cap (3) in the opening / closing swing direction. , It is difficult to plastically deform and the elastic restoring force is stable, so the fitting surface pressure between the water-impervious ridges (11) and the water-impervious ridges (6) is maintained at the design value with high accuracy.
The water-blocking performance between these mating surfaces is kept high, and rainwater can be more strongly prevented from passing through between these mating surfaces and entering the roof wall (24) of the building (23) and leaking. .

Invention 3. Claim 3. See FIG. 7 or FIG. First, the present invention 3 has the same effects as those of the above invention 1 in terms of the effects [A], [B], [C] and [D] of the above invention 1 Play. The invention 3 has the following effects from the components that are not common to the invention 1.

[F. Rainwater on the roof plate (1) is a skirt
It is difficult to flow a large amount into the inside of the (12), and the large buffer space (14) inside the skirt (12) stalls and drops the rainwater so that even when the wind and wind are strong, the rainwater will fall between the roof plates (1) (1). It strongly prevents the leakage of rain from the connecting portion between them into the roof wall (24) of the building (23). ]

According to the third aspect of the present invention, the flow of rainwater on the roof plate (1) being pushed into the skirt (12) by a strong wind such as a storm or a typhoon is limited by the narrow dust outflow gap (21). It Therefore, the rainwater is prevented from freely flowing into the skirt (12) in a large amount. Part of that rainwater is a skirt (1
Even if it penetrates into the inside of 2), the force of the flow of the invading water is rapidly weakened due to the rapid spread from the contact surface to the wide buffer space (14). This weakened invading water is
It collides with the rising connection edge (4) from (1) and is easily bounced off, smoothly falling in the wide buffer space (14), and between the abutment surfaces of the skirt lower edge (13) and the roof plate (1). Smoothly flows from the outside.

As a result, the invading water in the buffer space (14) almost never passes upward between the contact surfaces of the water-blocking ridges (6) and the water-blocking ridges (11), which prevents rain and wind from entering. Even when strong
It is possible to strongly prevent rainwater from leaking into the roof wall (24) of the building (23) from the connecting portion between the roof plates (1) (1).

[G. Rainwater flowing over the roof plate (1) removes dust accumulated in the buffer space (14) from the dust outflow gap (21).
By washing away from the roof to the outside, the dust accumulated in the buffer space (14) and the rainwater absorbed by the roof plate (1)
Eliminates the start of corrosion. ]

External dust is blown by the wind and enters the buffer space (14) in the skirt (12) through the dust outflow gap (21) and tries to accumulate there. Roofing boards when it rains
(1) Part of the rainwater flowing above flows into the buffer space (14) in the skirt (12) from the dust outflow gap (21), and the dust accumulated there is discharged from the dust outflow gap (21). Rinse to the outside. As a result, dust does not accumulate in the buffer space (14), and the roof plate (1) is prevented from being corroded by the dust accumulated here and the rainwater absorbed by the dust. The durability of the roof plate (1) can be improved.
