[0014]

In the prior art 1 described above,
There are the following problems. [A. The rainwater blown up along the rising connection edge (4) by strong wind flows vigorously to the water blocking ridge (6), so that the water blocking ridge (6) of the rising connection edge (4) and the cap (3)
Of the building (23) from the connection between the roof shingles (1) and (1) when the rainy winds are strong. May leak into the roof wall (24). ]

When a rainstorm such as a storm or a typhoon blows strongly, a part of the rainwater flowing on the roof plate (1) is strongly pushed by the strong wind and rises along the rising connection edge (4).
It flows vigorously into the impermeable ridges (6). For this reason, the rainwater is impervious to the impermeable grooves (11) on the side plate (10) of the cap (3) and the roof plate.
The rising connection edge (1) of (1) passes upward between the fitting and contact surfaces of the water-impervious ridges (6) and flows down in the cap (3),
After passing between the facing surfaces of the left and right rising connection edges (4) and (4), the building
Intrusion into the building (23) from the roof wall (24) of (23) may cause rain leakage.

[B. When both caps (11) and (11) of the cap (3) are opened to the left and right by elastic deformation when the cap (3) is about to be lifted by a disturbance force, the caps (3) are closed.
(6) Since (6) remains stationary, both impermeable ridges (11) (1)
The fitting between 1) and the water-impervious ridges (6) (6) gradually weakens, and the cap (3) tends to come off due to disturbance force. ]

As shown in FIG. 9, the left and right impermeable recesses (11) and (11) of the cap (3) are connected to the upright connecting edges (4) and (4) of the left and right roof plates (1) and (1). The cap (3) is fitted to the water-blocking ridges (6) and (6) from above, and the cap (3) is assembled to the connection between the shingles (1) and (1).

In the state after the assembly shown in FIG. 9, the cap (3) is lifted by some disturbance force so that the two impermeable grooves (11) and (11) of the cap (3) are elastically deformed right and left. When open, both impermeable ridges (6) and (6)
(11) In (11), it is pushed to the hanging member (2) side and remains stationary.
For this reason, as the two impervious concave strips (11) and (11) move out of the two impervious convex strips (6) and (6), the two impervious concave strips (11) and (11) As the engagement with the ridges (6) and (6) gradually weakens,
The cap (3) tends to come off due to disturbance force.

[C. Rainwater on the roof shingle (1)
(112) (212) It is easy to flow into the building, so when rain is strong, rainwater flows from the connection between the shingles (1) and (1) to the building (23).
There is a risk of rain leaking into the roof wall (24). ]

When a strong wind such as a storm or a typhoon blows, a part of the rainwater flowing on the roof plate (1) is pushed vigorously by the strong wind, and the skirts (112) and (212) of the cap (3).
Into the inside of the cap (3).
1) and the rising connection edge (4) of the roof panel (1) passes upwardly between the fitting contact surfaces of the impermeable ridges (6) and flows down in the cap (3), and the left and right rising connections There is a possibility that rain may leak from the roof wall (24) of the building (23) into the building (23) through the space between the facing surfaces of the edges (4) and (4).

[D. Roof panel due to 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 strongly, the negative pressure generated by the wind may cause the roof shingle (1) to be sucked up and lifted up, and may be peeled off from the roof wall (24) of the building (23).

[E. The suspension (2) is attached to the shingle (1)
Since the positioning is not automatically performed accurately in the horizontal direction by simply contacting, the mounting pitch between the hangers (2) and (2) is measured and marked in advance. Marking work (inking work) is required. ]

With respect to the rising connection edge (4) of the roof slab (1) already fixed to the roof wall (24) of the building (23), the slat (2) is sandwiched between the roof slab (1) and the roof slat (1) to be fixed next. ) Is pressed against the rising connection edge (4), the rising base (1) of the rising connection edge (4) is pressed.
15) Since (115) is away from the suspension (2),
(4) is easily rocked and deformed, and the suspension (2) is not automatically and accurately positioned in the lateral direction simply by making contact with the roof plate (1). As a result, the roof wall (24) of the building (23)
Before installing the roof slabs (1) in the horizontal direction and connecting and fixing them on the entire surface of the slab, measure the installation pitch between the stubs (2) and (2) in advance and scribe them. Preliminary scoring work (inking work) for the mounting pitch is required.

[F. Roof slab due to negative pressure generated by strong wind
The suction force of (1) rises and the rising base (115) of the connecting edge (4) rises
(215) is bent up, so the roof panel is
(1) may be peeled off from the roof wall (24) of the building (23). ]

In a strong wind, when the roof slab (1) is about to be sucked up by a negative pressure, the mooring portion (5) of the rising connection edge (4).
The rising bases (115) and (215) of the rising connecting edge (4) are farther away from the mooring portion received by the mooring portion (8) of the suspension (2) toward the roof plate (1) than directly below. Position. For this reason, most of the force for lifting the roof base (115) (215) of the rising connection edge (4) due to the suction force of the roof slab (1) due to the negative pressure generated by the strong wind is applied to the mooring section (8). It is not absorbed, and serves as a force to bend up the rising base portions (115) and (215) with the mooring portion (5) as a fulcrum.

Thus, the suction force of the roof plate (1) due to the negative pressure generated by the strong wind causes the rising base (1) of the rising connecting edge (4) to rise.
15) Since (215) is bent up, the shingle (1) may be peeled off from the roof wall (24) of the building (23) due to the negative pressure generated by the strong wind.

[G. When the worker puts the cap (3) on the upright connecting edges (4) and (4) and the suspension (2), the left and right skirts (112), (112), (212) and (212) of the cap (3) twenty one
2) This cap only needs to be pryed open.
(3) The assembling work is complicated and time-consuming. ]

Left and right roof panels (1)
(4) After connecting (4) to the roof wall (24) of the building (23) by means of the suspension (2), the cap (3) is connected to the rising edge (4) (4) and the suspension (2). ) And assemble.

The left and right skirts (112) and (112) of the cap (3)
(212) The width between both lower edges (113), (113), (213), and (213) of (212) is the width between both rising connection edges (4) and (4), and the
It is narrower than the full width of (2). For this reason, workers
When putting (3) on both rising connection edges (4) and (4) and the suspension (2), the left and right skirts (112) of the cap (3)
(112) (212) The operation of assembling the cap (3) is complicated and labor-intensive because the operation of prying open the (212) is required.

[H. The small-diameter circular ridges (120) and (220) are easily plastically deformed and the elastic restoring force becomes unstable.
It is difficult to maintain the fitting surface pressure between the 1) and the water impervious ridge (6) with high accuracy, the water blocking performance between the fitting surfaces is reduced, and the rainwater passes between the fitting surfaces, and the building There is a danger that it will enter the roof wall (24) of (23) and leak. ]

When assembling the cap (3) over the upstanding connecting edges (4) and (4) of the left and right roof slabs (1) and (1) and the hangers (2), the cap (3) When the water-impervious groove (11) rides on the water-impervious ridge (6) of the rising connection edge (4) and then fits, the skirt (112) (212) and the side plate (10) of the cap (3) are It is pushed out to the left and right outside, and the small-diameter arc ridge (12
0) (220) exceeds the elastic deformation limit and tends to be plastically deformed.

The small-diameter arc ridges (120) and (220) are
(3) Since the maximum elastic deformation dimension of the left and right side plates (10) and (10) in the opening and closing swing direction with respect to the top plate (9) is small, it is easy to plastically deform and the elastic restoring force is difficult to stabilize. It becomes difficult to maintain the fitting surface pressure between the concave streak (11) and the water impervious ridge (6) at a design value with high accuracy, the water impermeability between the mating surfaces is reduced, and rainwater There is a risk of passing through the surfaces and invading the roof wall (24) of the building (23) to leak.

An object of the present invention is as follows. (A). Rainwater that has been blown up along the rising connection edge by strong wind rises to the rainwater rising reversal space and then reverses and falls, so that even when strong rainy wind is strong, rainwater flows from the connection between the roof plates. Strongly prevents rain from leaking into the roof of a building. (B). When the cap is about to be dislodged by disturbance force, the fitting between the impermeable ridge and the impermeable recess is strengthened to increase the force with which the cap is dislodged by the disturbance force. .

(C). In addition to making it difficult for the rainwater on the shingle to flow into the skirt of the cap, and by stalling the skirt, the rainwater leaks from the connection between the shingles into the roof wall of the building even when the rainy winds are strong. Is more strongly prevented. (D). By pressing the shingle at the lower edge of the skirt, the shingle is strongly prevented from being peeled from the roof wall of the building by the negative pressure created by the strong wind.

(E). By simply positioning the hangers against the shingle and automatically positioning them in the horizontal direction, the mounting pitch between the hangers is measured and marked in advance. Preliminary scoring work (inking work) of the mounting pitch is omitted, and the work of connecting and fixing the roof slabs is simplified. (F). The shingle is peeled from the roof wall of the building by the negative pressure generated by the strong wind by preventing the wicking force of the shingle from being lifted by the negative pressure generated by the strong wind from bending the rising base of the rising connection edge of the shingle. To prevent that.

(G). The operator simply puts the cap on the upright connecting edge and the core of the shingle and steps on it with his foot. You can find it. (H). By making the cap difficult to plastically deform,
The fitting surface pressure between the impermeable ridge of the cap and the impermeable ridge on the rising connection edge of the roof slab is maintained with high precision, and the impermeable performance between the fitted surfaces is maintained at a high level.

(I). In addition to making it difficult for the rainwater on the shingle to flow freely into the skirt of the cap, the stormwater flows between the shingles even when the rainy winds are strong, because the inflowing rainwater stalls and falls in the large buffer space inside the skirt. Prevents rain from leaking into the roof of the building from the connection. (J). Dust that has accumulated in the buffer space inside the cap skirt is washed out with the rainwater flowing on the roof plate and allowed to go, so that the dust that has entered and accumulated in this buffer space and the rainwater absorbed by the dust Eliminates corrosion of the board.

[0046]

The connection structure between the vertically shingled metal shingles of the present invention has the following effects. ○ Invention 1. Claim 1. See FIG. 1 to FIG. 5, FIG. 6, FIG. 7 or FIG. [A. The rainwater that has been blown up along the rising connection edge (4) by the strong wind rises to the rainwater rising reversal space (26) and then reverses and falls, and the roof plate from the rainwater entrance / exit gap (27)
(1) In order to fall upward, it is strongly pushed between the watertight ridges (6) of the rising connection edge (4) and the watertight concave ridges (11) of the cap (3). It prevents rainwater from leaking into the roof wall (24) of the building (23) from the connection between the roof slabs (1) even when the wind and rain are strong, . ]

When a strong wind such as a storm or a typhoon blows, a part of the rainwater flowing on the roof plate (1) is pushed vigorously by the strong wind and rises along the rising connection edge (4).
Passing upward between the contacting and abutting surfaces of the impermeable ridges (11) of the side plate (10) of the cap (3) and the ridges (6) of the rising connection edge (4) of the roof slab (1). Then, it flows down in the cap (3), enters the building (23) from the roof wall (24) of the building (23) through the opposing surfaces of the right and left rising connection edges (4) and (4), Leakage may occur.

According to the first aspect of the present invention, when a part of the rainwater on the roof panel (1) is blown toward the rising connection edge (4) by the strong wind, it is blown up along the rising connection edge (4). Then, it rises from the rainwater entrance / exit gap (27) to the rainwater rising / reversing space (26), reverses and falls, and falls from the rainwater entrance / exit gap (27) onto the roof plate (1).

Thus, the connecting edge (4) rising by strong wind
The rainwater that has been blown up along the
Since the water does not pass upward between the mating and contacting surfaces of the impermeable ridge (6) of (4) and the impermeable ridge (11) of the cap (3), even when the rainy wind is strong, the rainwater can be (1) It is possible to strongly prevent rain from leaking from the connection between the (1) and the roof wall (24) of the building (23).

[B. When the cap (3) is about to be dislodged by disturbance force, the water-impervious ridges (6) and (6) spread out to the left and right sides and laterally outward to form the water-impervious recesses (11) and (11). Since the fitting becomes stronger, the force withstanding that the cap (3) comes off due to the disturbance force becomes stronger. ] As shown in FIG.
(3) The left and right impermeable ridges (11) and (11) are the left and right shingles (1) (1)
The cap (3) is fitted to the connection between the roof shingles (1) and (1) by fitting from above into the impermeable ridges (6) and (6) of the both rising connection edges (4) and (4). Can be

In the state after the assembly in FIG. 2, when the cap (3) is lifted by some disturbance force, the cap (3) passes through the left and right water-impervious concave strips (11) and (11). Then, the two impermeable ridges (6) and (6) which are fitted in this are going to be pushed up. The two impermeable ridges (6) and (6) are
1) When trying to be pushed up in (11), each rising connecting edge
(4) With the upper end edge of (4) as a fulcrum, it spreads out to both left and right sides, and the fitting with both water-impervious concave stripes (11) and (11) becomes stronger.
For this reason, the force withstanding that the cap (3) comes off due to the disturbance force is increased.

○ Invention 2 Claim 2. See FIG. 1 to FIG. 5 or FIG. The second aspect of the invention has the following effects in addition to the effects [A] and [B] of the first aspect. [C. The rainwater on the roof shingle (1) does not easily flow into the skirt (12), and the large buffer space (1
Because the vehicle stalls and falls in 4), even when the wind and rain are strong, rainwater flows from the connection between the shingles (1) and (1) to the roof wall (2) of the building (23).
4) Prevent the leakage into the interior more strongly. ]

According to the second aspect of the present invention, the rainwater on the shingle (1) that is about to be pushed into the skirt (12) by the strong wind is
Since the lower edge (13) of (2) is in contact with the shingle (1), most of the rainwater is prevented from flowing into the skirt (12) from between the contact surfaces. A small part of that rainwater is a skirt (1
2) Even if it intrudes into the interior, the momentum of the flow of the intruding water rapidly decreases due to the sudden spread from the contact surface to the large buffer space (14). The weakened intrusion water is
From (1), it collides with the rising connection edge (4) and is easily bounced off, falls smoothly in the large buffer space (14), and smoothly falls between the lower edge of the skirt (13) and the roof plate (1). Flows out smoothly from the outside.

As a result, the infiltrating water in the buffer space (14) hardly passes upward between the contact surfaces of the impermeable ridges (6) and the impermeable ridges (11). Even when strong
It is possible to further strongly prevent rainwater from leaking into the roof wall (24) of the building (23) from the connection between the shingles (1).

[D. Since the lower edge (13) of the skirt (12) presses the shingle (1), make sure that the shingle (1) is peeled off from the roof wall (24) of the building (23) by the negative pressure generated by the strong wind. Strongly prevent. When a strong wind such as a storm or a typhoon blows strongly, the negative pressure generated by the wind causes the roof shingle (1) to be sucked up and to be peeled off from the roof wall (24) of the building (23). In the present invention 2, in the lower edge (1) of the skirt (12),
Since 3) presses the shingle (1), it is possible to strongly prevent the shingle (1) from being peeled off from the roof wall (24) of the building (23) due to the negative pressure caused by the strong wind. .

○ Invention 3. Claim 3. 1 to 5,
See FIG. 6, FIG. 7 or FIG. The third aspect of the invention has the following effects in addition to the effects [A] and [B] of the first aspect.

[E. The suspension (2) is attached to the shingle (1)
It is automatically and accurately positioned in the horizontal direction just by contacting. Therefore, the installation pitch between the suspensions (2) and (2) is measured and marked in advance. Since the preliminary scoring work (inking work) can be omitted, the work of connecting and fixing the roof slab (1) is simplified, and the work efficiency is greatly improved. ]

With respect to the rising connection edge (4) of the roof slab (1) already fixed to the roof wall (24) of the building (23), the hanging slat (2) is sandwiched, and the roof slat (1) to be fixed next is placed. ) Is pressed against the rising connection edge (4), the rising base (1) of the rising connection edge (4) is pressed.
5) abuts on the suspension (2), so that the rising connection edge (4) does not swing and deform, and the suspension (2) is simply brought into contact with the roof plate (1). Automatically and laterally accurately.

Thus, before the roof slats (1) are arranged side by side in the horizontal direction on the entire surface of the roof wall (24) of the building (23) and fixedly connected thereto, the space between the hangers (2) and (2) is previously determined. Simplifying the connection and fixing work of the roof slab (1) is equivalent to the omission of the preliminary scoring work (inking work) of the hanging pitch in the horizontal direction, in which the installation pitch is measured and marked. , The work efficiency can be greatly increased.

[F. Roof slab due to negative pressure generated by strong wind
Since the suction force of (1) does not bend the rising base (15) of the rising connection edge (4), the roof plate (1) is pulled from the roof wall (24) of the building (23) by the negative pressure generated by the strong wind. Strongly prevents peeling. ]

In a strong wind, when the roof slab (1) is about to be sucked up by negative pressure, the mooring portion (5) of the rising connection edge (4).
