9 is a longitudinal sectional front view of the recessed part showing the prior art 1, and FIG. 10 is a longitudinal sectional front view of the recessed part showing the prior art 2. FIG.

The vertical roof joint type metal roof plate is connected to each other by a roof plate 1 made of a metal plate, a mooring piece 2, and a cap 3. The left and right side edges of the roof plate 1 are folded to form standing connection edges 4 of each of the left and right sides. A mooring part 5 is formed in a part of the standing connecting edge 4. A water film convex portion 6 is formed to smoothly inflate toward the roof plate 1 at an intermediate height of the standing connecting edge 4.

The mooring piece 2 is provided with a base portion 7 fixed to the roof wall 24 of the building 23 and a pair of left and right mooring portions 8.

The cap 3 is formed by bending a pair of left and right side plates 10 from the left and right side edges of the ceiling plate 9. The water film concave part 11 which faces inward to this left and right side plate 10 is swelled smoothly horizontally outward, and bend | folded.

The standing connecting edges 4 of each of the left and right roof plates 1 and 1 are disposed at the left and right lateral outer sides of the mooring piece 2. The mooring part 5 of each standing connecting edge 4 is comprised so that the mooring part 8 of the left and right of the mooring piece 2 may be supported from above.

Cover the cap 3 from the top across the mooring piece 2 and the left and right standing edges 4, and the left and right angles of the cap 3 on the convex portions 6 of both standing edges 4, respectively. The water film is brought into contact with the recess 11 in a state where it is fitted in close contact with the outside.

As a specific structure for combining the cap 3 with the roof plate 1 and the mooring piece 2 in the above-described preliminary configuration, the following are known as prior arts.

Fig. 9 shows the prior art 1 disclosed in Japanese Patent No. 2633003, which is a longitudinal front view of the main portion.

Each skirt 112 of the left and right side plates 10 of the cap 3 extends extremely short from the recess 11 and protrudes. The lower edge 113 of the skirt 112 is also separated from the standing connecting edge 4 at a high distance from the roof plate 1. In this standing connecting edge 4, the standing midway portion 116 and the standing upper part 117 are formed to advance toward the mooring piece 2 with respect to the standing base portion 115.

The lower edge 113 of the skirt 112 of the cap 3 is directed toward the center of the mooring piece 2 rather than each part of the standing connecting edge 4 of the roof plate 1 and each part of the mooring piece 2. It is located after being pulled in. A small circular arc convex portion 120 having a small radius of curvature is interposed between the ceiling plate 9 of the cap 3 and the left and right side plates 10.

Fig. 10 shows a prior art 2 disclosed in Japanese Patent Laid-Open No. 10-61121, which is a longitudinal front view of a main portion.

Each water film of each side plate 10 on the left and right sides of the cap 3 extends from the recess 11 so that each skirt 212 is extremely short. The lower edge 213 of the skirt 212 is also separated from the standing connecting edge 4 at a high distance from the roof plate 1. In the standing connecting edge 4, the standing midway portion 216 and the standing upper part 217 are formed to advance toward the mooring piece 2 with respect to the standing foundation portion 215.

The lower edge 213 of the skirt 212 of the cap 3 is directed toward the center of the mooring piece 2 rather than each part of the standing connecting edge 4 of the roof plate 1 and each part of the mooring piece 2. It is relocated. A small circular arc convex portion 220 having a small radius of curvature is interposed between the ceiling plate 9 of the cap 3 and the side plates 10 on the left and right sides.

The prior art 1 and the prior art 2 have the following problems.

A. Rainwater on the roof plate 1 is likely to flow into the skirts 112 and 212, so when the rainstorm is strong, the rainwater is the roof wall of the building 23 at the connections between the roof plates 1 and 1 (24) There is a fear of rain inside.

When a strong wind blows, such as in a storm or typhoon, part of the rainwater flowing on the roof plate 1 is strongly pushed by the strong wind and pushed into the skirts 112 and 212 of the cap 3 so that the cap 3 side plate ( 10, the water film of the concave portion 11 and the standing connecting rim 4 of the roof plate 1 is tightly fitted between the convex portion 6 and passes through the abutting surface, and flows down into the cap 3, left and right Passing between opposing surfaces of both standing connecting edges (4) and (4), there is a possibility that water leaks into the building 23 from the roof wall 24 of the building 23.

B. There is a fear that the roof plate 1 is peeled off from the roof wall 24 of the building 23 due to the negative pressure generated by the strong wind.

When the wind blows strongly, such as a storm or a typhoon, the roof plate 1 is drawn up and floated by the negative pressure generated by the wind, and it may be pulled off from the roof wall 24 of the building 23 and peeled off. .

C. Since the mooring pieces 2 are not automatically positioned correctly in the transverse direction simply by bringing them into contact with the roof plate 1, the attachment pitch between the mooring pieces 2 and 2 is measured in advance. A preliminary file marking work is required for the lateral attachment pitches of mooring pieces marked with files.

The standing plate of the roof plate 1 fixed with the mooring piece 2 interposed therebetween with respect to the standing connecting edge 4 of the roof plate 1 already fixed to the roof wall 24 of the building 23. When the connecting edge 4 is pressed, the standing foundation portions 115 and 115 of the standing connecting edge 4 are separated from the mooring piece 2, so that the standing connecting edge 4 easily swings. Deformed, the mooring piece 2 is not automatically positioned correctly in the transverse direction only by making it contact with the roof plate 1.

Therefore, before the roof plate 1 is connected to the front of the roof wall 24 of the building 23 side by side in a lateral direction and fixed, the attachment pitch between the mooring pieces 2 and 2 is measured in advance. A preliminary file marking work (marking line work) of the lateral attachment pitch of the mooring piece to be marked is necessary.

D. Since the suction force of the roof plate 1 due to the negative pressure generated by the strong wind bends the standing foundation portions 115 and 215 of the standing connecting edge 4, the roof plate 1 due to the negative pressure generated by the strong wind. ) May be pulled away from the roof wall 24 of the building 23.

With respect to the mooring portion supported by the mooring portion 8 of the mooring piece 2 by the mooring portion 5 of the standing connecting edge 4 when the roof plate 1 is to be sucked up by negative pressure during strong wind. The standing foundations 115 and 215 of the standing connecting edge 4 are located farther toward the roof plate 1 than directly below the vertical direction. For this reason, most of the force that the suction force of the roof plate 1 due to the negative pressure caused by the strong wind tries to push up the standing foundation portions 115 and 215 of the standing connecting edge 4 is applied to the mooring portion 8. It is not absorbed, and it becomes a force which tries to bend the standing foundation parts 115 and 215 by making into the to-hold part 5 as a point.

As a result, the wicking force of the roof plate 1 due to the negative pressure generated by the strong wind bends the standing foundation portions 115 and 215 of the standing connecting edge 4, so that the roof plate ( 1) There is a fear of being pulled away from the roof wall 24 of the building 23.

E. Since the cap 3 is only fitted to the roof plate 1 and is fixed, the fixing force is relatively weak, and the cap 3 is disturbed from the roof plate 1 and the mooring piece 2. And external turbulence force).

The cap 3 is fixed to the roof plate 1 only at the portion where the water curtain recessed portion 11 and the water film are fitted between the convex portions 6, so that the cap 3 is weakly fixed, and the cap 3 is the roof plate 1. And peeling from the mooring piece 2 due to disturbance force.

F. Skirts 112, 112, 112 and 212 on the left and right sides of the cap 3 when the operator covers the cap 3 on both standing connecting edges 4 and 4 and the mooring piece 2. As the operation of forcibly opening the space is required, the assembling work of the cap 3 becomes complicated and requires a lot of hands.

After fixing both standing connecting edges 4 and 4 of the left and right roof boards 1 and 1 to the roof wall 24 of the building 23 by the mooring piece 2, the cap 3 is standing up. It is assembled by covering the connecting rim (4) (4) and the mooring piece (2).

The left and right edges of the cap 3, 112, 112, 212, 212, and the lower edges 113, 113, 213, and 213, respectively. It is narrower than the width of and the total width of the mooring piece (2). For this reason, when an operator covers and assembles the cap 3 on both upright connecting edges 4 and 4 and the mooring piece 2, the skirts 112, 112 and 112 of the left and right sides of the cap 3 are assembled. As the operation of forcibly opening 212 is required, the assembling work of the cap 3 becomes complicated and requires a lot of hands.

G. Since the small-circular arc convex portions 120 and 220 are easily plastically deformed and the elastic restoring force becomes unstable, it is difficult to maintain the pressure of the convex portion 11 and the convex portion 6 of the water film with high accuracy, The waterproof performance between the fitting surfaces decreases, and rainwater may pass through the fitting surfaces and enter the roof wall 24 of the building 23 to rain.

In the case where the cap 3 is covered with both standing connecting edges 4 and 4 and the mooring piece 2 of the left and right roof plates 1 and 1, the water film of the cap 3 is recessed ( 11) When the water film of the standing connecting edge 4 is put on the convex portion 6 and then fitted, the skirts 112 and 212 and the side plate 10 of the cap 3 are pushed outward to the left and right, and the small diameter The circular arc convex portions 120 and 220 are easily elastically deformed beyond the elastic deformation limit.

The small circular arc convex portions 120 and 220 are easily plastically deformed because the maximum elastic deformation dimension in the opening and closing swing direction of the left and right side plates 10 and 10 with respect to the ceiling plate 9 of the cap 3 is small. Since the elastic restoring force becomes difficult to stabilize, the fitting surface pressure of the water film recessed portion 11 and the water film convex portion 6 becomes difficult to be maintained with high accuracy within the design value, and the waterproof performance between the fitting surface is lowered, resulting in rain water. There is a fear that the rain penetrates through the fitting surfaces and enters the roof wall 24 of the building 23.

The problem of this invention is as follows.

(A). It not only makes rainwater on the roofboard less likely to flow into the skirt of the cap, but also by slowing it down in the skirt, which strongly prevents rainwater from leaking into the building's roof walls at the joints between the roofboards, even when the weather is strong. do.

(B). By pressing the roof board against the bottom edge of the skirt, it is strongly prevented that the roof board is pulled off the roof wall of the building by the negative pressure generated by the strong wind.

(C). Since the mooring piece is automatically positioned precisely in the transverse direction by simply touching the roof plate, the preliminary file marking work of the mooring piece transverse attachment pitch is displayed by measuring the attachment pitch between the mooring pieces in advance. Omit the (line marking work), simplifying the fixing work of the roof plate.

(D). The suction force of the roof plate due to the negative pressure generated by the strong wind does not bend the standing foundation of the standing connecting edge of the roof plate, and prevents the roof plate from being pulled away from the roof wall of the building due to the negative pressure generated by the strong wind. .

(E). The cap is firmly inserted and fixed to the roof plate and the mooring piece to prevent the cap from being peeled off by the disturbance force on the roof plate and the mooring piece.

(F). The cap is firmly inserted against the roof plate and the mooring piece so that the bottom edge of the skirt of the cap strengthens the pressing force of the roof plate, and the roof plate is pulled from the roof wall of the building by the negative pressure generated by the strong wind. It prevents peeling more strongly.

(G). By simply placing the cap on both standing connecting edges and mooring pieces of the roof board and stepping on the feet, the operator can simply and efficiently assemble the cap outside both standing connecting edges and mooring pieces.

(H). The cap is less likely to be plastically deformed, so that the water pressure between the concave portion of the cap and the convex portion of the standing edge of the roof plate is maintained with high accuracy, and the waterproof performance between these fitting surfaces is maintained high.

(I). Not only does it make it difficult for large amounts of rainwater to flow freely into the skirt of the cap, but also by slowing and dropping the incoming rainwater in the wide buffer space inside the skirt, even when the weather is strong, the rainwater is connected to the roofboard. From leaking into the roof walls of buildings.

(J). The rainwater flowing on the roofboard washes away the foreign matter stuck in the cushioning space in the skirt of the cap to the outside, thereby eliminating corrosion of the roofboard by the foreign matter invaded and accumulated in the buffering space and the rainwater absorbed therein.

8 is a longitudinal sectional front view of the main portion showing the fourth embodiment of the present invention.

The fourth embodiment adds the large-diameter circular arc convex portion 20 and the cap receiving port 44 among the third embodiment shown in FIG. 7 and the second embodiment shown in FIG.

The connection structure between the vertical roof joint type metal roof plates according to the present invention has the following effects.

A. Since rainwater on the roof plate 1 is difficult to flow into the skirt 12 and is slowed down and dropped by the wide buffer space 14 inside the skirt 12, even when the rainstorm is strong, the rainwater can be applied to the roof. Strong connection is prevented from leaking into the roof wall 24 of the building 23 at the joints between the plates 1 and 1.

When a strong wind blows like a storm or a typhoon, a part of the rainwater flowing on the roof plate 1 is strongly pushed by the strong wind, pushed into the skirt 12 of the cap 3, and the side plate of the cap 3 The water film of (10) passes between the concave portion 11 and the standing edge of the standing plate edge 4 of the roof plate 1 upwardly between the fitting surface of the convex portion 6, and then flows down in the cap 3 and left and right. Passing between the opposing surfaces of both standing connecting edges (4) and (4), there is a case of leaking into the building 23 from the roof wall 24 of the building 23.

In the present invention 1, the rainwater on the roof plate 1 to be pushed into the skirt 12 by the strong wind, because the lower edge 13 of the skirt 12 abuts the roof plate 1, Most of it is prevented from flowing into the skirt 12 from between the abutting faces.

Even if only a part of the rainwater intrudes into the skirt 12, the intensity of the flow of the infiltrating water is rapidly weakened by the rapid expansion from the contact surface to the wide buffer space 14. This weakened invasion water collides with the standing plate border 4 from the roof plate 1 and is easily bounced back, and smoothly falls inside the wide buffer space 14, so that the skirt bottom edge 13 and It flows out smoothly from between the surface which contacted the roof board 1.

As a result, invasion water in the buffer space 14 rarely passes upward between the water-convex convex portion 6 and the water-contacting concave portion 11 in a upward direction, so that rainwater can be carried out even when the weather is strong. 1) (1) It can be strongly prevented from leaking into the roof wall 24 of the building 23 from the mutual connection.

B. Since the lower edge 13 of the skirt 12 is pressing the roof plate 1, the roof plate 1 is pulled away from the roof wall 24 of the building 23 by the negative pressure generated by the strong wind. Strongly prevent it.

When the wind blows strongly, such as a storm or a typhoon, the roof board 1 is sucked up by the negative pressure generated by the wind, and is pulled away from the roof wall 24 of the building 23.

In the present invention 1, the lower edge 13 of the skirt 12 presses the roof plate 1, so that the roof plate 1 is caught from the roof wall 24 of the building 23 by the negative pressure generated by the strong wind. It can be strongly prevented from being pulled off.

The present invention 2 exhibits the following effects in addition to the effects A and B of the first invention.

C. Since the mooring pieces 2 are accurately positioned in the transverse direction only by touching the roof plate 1, the mooring pieces 2 and 2 are measured in advance. Since the preliminary file display work (mold line display work) of the mooring piece lateral attachment pitch to be lined up can be omitted, the connection fixing work of the roof plate 1 is simplified and the work efficiency is greatly improved.

The standing connection of the roof plate 1 fixed next to the mooring piece 2 with respect to the standing connection border 4 of the roof plate 1 already fixed to the roof wall 24 of the building 23. When the edge 4 is pushed, the standing foundation 15 of the standing connecting edge 4 abuts against the mooring piece 2, so that the standing connecting edge 4 does not oscillate and deforms. 2) The position is automatically precisely determined laterally just by making contact with the roof plate 1.

For this reason, before the roof plate 1 is sequentially connected side by side in the transverse direction to the roof wall 24 front of the building 23, the attachment pitch between the mooring pieces 2 and 2 is measured in advance. Since the preliminary file marking work (marking line work) of the mooring piece transverse attachment pitch can be omitted, the connection fixing work of the roof plate 1 can be simplified and the work efficiency can be greatly improved.

D. Since the suction force of the roof plate 1 due to the negative pressure generated by the strong wind does not bend the standing foundation 15 of the standing connecting edge 4, the roof plate 1 is caused by the negative pressure generated by the strong wind. It is strongly prevented from being pulled away from the roof wall 24 of the building 23.

In the strong wind, when the roof plate 1 is to be sucked up under negative pressure, the mooring part 5 of the standing connecting edge 4 is supported by the mooring part 8 supported by the mooring part 8 of the mooring piece 2. On the contrary, the standing foundation 15 of the standing connecting edge 4 is located near the vertical direction below. For this reason, the force which the suction force of the roof board 1 by the negative pressure which arises from a strong wind tries to push up the standing base part 15 of the standing connection border 4 is mostly absorbed by the said mooring part 8, It is not a force which tries to bend the standing foundation part 15 with the mooring part 5 as a point.

As a result, the suction force of the roof plate 1 due to the negative pressure generated due to the strong wind does not bend the standing foundation portion 15 of the standing connecting edge 4, so that the roof plate 1 is caused by the negative pressure generated due to the strong wind. It is strongly prevented from being pulled away from the roof wall 24 of the building 23.

In addition to the effects A and B of the present invention 1, the present invention 3 exhibits the following effects.

E. As long as the cap 3 is fitted in two stages and fixed to the roof plate 1 and the mooring piece 2. Since the fixing force doubles, the cap 3 is strongly prevented from being peeled off by the disturbance force on the roof plate 1 and the mooring piece 2.

The cap 3 is fixed to the roof plate 1 and the mooring piece 2, and the fixed position of the convex portion 11 and the convex portion 6, and the separation prevention portion 10 and the separation prevention portion 18. Since the fixing force doubles as much as the two positions are fixed in the fixed position, the cap 3 can be strongly prevented from being peeled off due to disturbance force in the roof plate 1 and the mooring piece 2.

F. The force for pressing the roof plate 1 of the lower edge 13 of the skirt 12 of the cap 3 becomes strong, and the roof plate 1 is formed by the negative pressure generated by the strong wind, so that the roof wall of the building 23 ( 24) to prevent further pulling out and peeling off.

As described in the above effect E, the cap 3 is secured in two stages with respect to the roof plate 1 and the mooring piece 2, so that the cap 3 is strongly prevented from being peeled off by the disturbance force. When the lower edge 13 of the skirt 12 of the () is pressed against the roof plate 1, the force is increased, and the roof plate 1 is pulled from the roof wall 24 of the building 23 by the negative pressure generated by the strong wind. It can prevent it from falling off more strongly.

The present invention 4 exhibits the following effects in addition to the effects A and B of the first invention.

G. The operator attaches the cap 3 to both standing connecting edges 4 and 4 and the mooring piece 2, and attaches the cap 3 to both standing connecting borders 4, 4) and the mooring piece 2 can be assembled from the outside, and the assembling work of the cap 3 can be simplified and made highly efficient.

After fixing both standing connecting edges 4 and 4 of the left and right roof boards 1 and 1 to the roof wall 24 of the building 23 by the mooring piece 2, the cap 3 is lifted. It is assembled by attaching it to the upright connecting edge (4) (4) and the mooring piece (2).

When the cap 3 is placed on both standing connecting edges 4 and 4 and the mooring piece 2, both lower edges 13 and 13 of the left and right skirts 12 and 12 of the cap 3 Because it covers the full width of both standing rims (4) and (4) and the mooring piece (2), the operator merely places the cap (3) on both of the standing rims (4) and (4) and the mooring piece (2) By stepping out, the cap 3 can be assembled by assemble from the outside of both standing connecting edges 4 and 4 and the mooring piece 2. Thereby, the assembly | work of the said cap 3 can be simplified and high efficiency.

In addition to the effects A and B of the present invention 1, the present invention 5 exhibits the following effects.

H. Since the large-diameter circular arc convex portion 20 is difficult to plastically deform and the elastic restoring force is stable, the pressure between the concave portion 11 and the convex portion 6 of the water film is maintained at a high accuracy, and between these fitting surfaces. The water barrier performance is maintained high, and it is possible to more strongly prevent rainwater from penetrating into the roof wall 24 of the building 23 through the fitted surface.

In the case where the cap 3 is covered with both standing connecting edges 4 and 4 and the mooring piece 2 of the left and right roof boards 1 and 1, the water film of the cap 3 is recessed. ), When the water film of the standing connecting edge 4 rises on the convex part 6, the skirt 12 and the side plate 10 of the cap 3 are pushed outward to the left and right, and the large diameter circular convex part 20 is opened. ) Elastic deformation.

Since the large-diameter circular arc convex part 20 enlarges the maximum elastic deformation dimension of the opening / closing swing direction of the left and right side plates 10 and 10 with respect to the ceiling plate 9 of the cap 3, it becomes difficult to plastically deform. Since the elastic restoring force is stabilized, the fitting surface pressure between the concave portion 11 and the convex portion 6 of the water film is maintained with high accuracy within the design value, and the water film performance between the fitting surface is maintained high, so that rainwater is It is possible to more strongly prevent leakage and intrusion into the roof wall 24 of the building 23 through the fitting surfaces.

The present invention 6 exhibits the following effects.

I. Rainwater on the roof plate 1 becomes difficult to freely flow into the skirt 12 in a large amount, and also decelerates and falls in the wide buffer space 14 inside the skirt 12, so that the rainwater is strong even when the weather is strong. It is strongly prevented from leaking into the roof wall 24 of the building 23 at the connection between the roof plates 1 and 1.

In the present invention 6, the flow of the rainwater on the roof plate 1 to be pushed into the skirt l2 by a strong wind, such as during a storm or typhoon, is limited to the gap 21 for narrow foreign matter outflow. For this reason, the rainwater does not flow freely into the skirt 12 in large quantities.

Even if a part of the rainwater intrudes into the skirt 12, the momentum of the flow of the infiltrating water is rapidly weakened by the rapid expansion to the wide buffer space 14 between the fitting surfaces. The infiltrating water which has weakened this force collides with the standing board edge 4 from the roof board 1, and is easily bounced back, and falls smoothly inside the large buffer space 14, and the skirt lower edge 13 and the roof board It flows out smoothly between the fitting surface with (1).

As a result, the intrusion water in the buffer space 14 hardly passes upward between the contact surface of the convex portion 6 and the concave portion 11 of the water film, so that the rainwater is even when the rainstorm is strong. (1) It is possible to strongly prevent leakage into the roof wall 24 of the building 23 at the mutual connection.

J. Since the rainwater flowing on the roof plate 1 washes the foreign matter gathered in the buffer space 14 outward from the gap 21 for foreign matter discharge, the foreign matter accumulated in the buffer space 14 and the The corrosion of the roof plate 1 by the absorbed rain water is eliminated.

The foreign matter is blown by the wind, and tries to remain in the buffer space 14 in the skirt 12 from the gap 21 for the foreign matter outflow.

When it rains, a part of the rainwater flowing on the roof plate 1 flows into the buffer space 14 in the skirt 12 from the gap 21 for foreign matter outflow, and the foreign matter collected therein is stored in the gap for foreign matter outflow. I let you wash out from 21.

As a result, foreign matters do not accumulate in the buffer space 14, thereby eliminating corrosion of the roof plate 1 by the foreign matter accumulated therein and rainwater absorbed therein, thereby improving durability of the roof plate 1. It can increase.
