The ridge-side ends b, b are fixed to the roof receiving frames d, d fixed to c via the suspenders i, i, and a ridge board e having a width covering the ridge-side ends b, b. Are fastened to the ridge-side ends b, b with fasteners f, f such as drill screws and rivets. In addition, water surface doors g and g are attached to the edges b1 and b1 of the ridge-side end portions b and b by fitting, and aprons h and h are installed near the water surface doors g and g. There is.

The water surface door g is provided in order to prevent wind and rainwater from being blown up through the troughs of the roof board a and to prevent wind and rainwater from climbing over the edge b1 and entering the room. The opening of the valley surrounded by the edge b1 is closed. Further, the apron h is provided to prevent wind and rainwater from being blown up through the valley portion of the roof plate a at the front side portion of the water surface door g to some extent. Each of the water surface door g and the apron h is manufactured by performing various mechanical processes such as punching and bending on the metal plate so as to match the folded shape of the roof plate a.

However, if the water surface door g made of a metal plate is simply fitted and attached to the end edge b1 of the metal roof plate a, the space between the roof plate a and the water surface door g is inevitable. It is difficult to avoid the formation of a gap, which makes it difficult to completely prevent wind and rainwater from entering the room through the gap, and the roof plate a has a complicated shape. In this case, it becomes difficult to manufacture the water surface door g in conformity with the shape of the roof plate a, and the above-mentioned gap is more likely to occur. Further, there is a problem that it takes time and effort to attach the water surface door g to the edge b1 of the roof plate a.

Reference numeral 1 is a base material such as a beam made of C-shaped steel or the like, and 2 is a metal folding roof plate.

A gate-shaped roof receiving frame 4 is fixed to the base material 1 via a mounting seat 41 thereof, and a hanger 43 is fixed to a top plate portion 42 of the roof receiving frame 41. The hanger 43 has upwardly projecting portions 44, 44 on both sides and also has downwardly engaging pieces 45, 45.

The metal fold plate roof plate 2 is made of a color steel plate backed with a heat insulating material 3, and both ends in the front-rear direction X are bent into a symmetrical special shape. That is, as shown in FIG. 2 and FIG. 3, the end portion of the roof plate 2 has a lower-stage rising portion 23 and a lower-stage rising portion 23 that are raised from the roof plate main body 21 via the stepped portion 22. Return part 24 protruding inward from the upper end of the upper part, the upper stage side rising part 25 further raised from the returning part 24, and a substantially U-shape protruding outward from the upper end of the upper stage side rising part 25. The insulative portion 3 is provided with a fold portion 26 and a bent piece portion 27 that is bent inward at the edge of the dent portion 26. The heat insulating material 3 includes the bent piece portion 27 and the rising portion of the dent portion 26. It is provided over the entire part except the part. Further, the roof plate main body 21 is formed with ribs 28 bulging downward at predetermined positions.

A recessed portion between the upper-stage-side rising portion 25 and the recessed portion 26 at the end of the roof plate 2 is fitted into the protruding portion 44 of the hanger 43. In this way, the adjacent roof plates 2 and 2 arranged on both sides of the suspension 43 face each other with their recesses 26, 26 facing each other. Then, a metal clip 5 is fitted in this butting portion, and the ends of the adjacent roof plates 2 and 2 are joined by this clip 5. As shown in detail in FIG. 5, the clip 5 integrally includes an upper plate portion 52 having a V-shaped grooved rib 51 and a pair of leg portions 54, 54 having an engaging piece portion 53. By engaging the clip 5 with the abutting portion from above, the engaging piece portions 53, 53 are engaged with the return portions 24, 24 of the roof boards 2, 2. Reference numeral 6 is a cap made of a long metal body having a gate-shaped cross section, on which a heat insulating material 62 is attached. The cap 6 has engaging portions 61, 61 projecting inwardly on each of the pair of leg pieces. The cap 6 is fitted from above the clip 5, and the engaging portions 61, 61 are engaged with the return portions 24, 24 of the roof boards 2, 2 or the engaging piece portions 53, 53 of the clip 5.

The roof plates 2 are connected in the front-rear direction of the roof by the structure described above. On the other hand, the roof plates 2 and 2 arranged on the left and right of the ridge face each other with the ridge-side end portions 2a and 2a facing each other with a space therebetween, as shown in FIG. Aprons 7, 7 are arranged at the valleys of the ridge-side ends 2a, 2a of the left and right roof plates 2, 2. As shown in FIG. 4, the apron 7 is formed by bending a flange portion 72 over the entire width at the upper edge of the plate-shaped apron body 71, and attaching pieces 73, 73 to both ends of the flange portion 72. Is sticking out. The flange portion 72 and the mounting pieces 73, 73 project in opposite directions. Further, a bulge portion 74 is formed at the lower edge of the apron body 71, and projecting pieces 75 and 76 are formed at each end portion in the width direction of the apron body 71. Then, as shown in FIG. 2, the bulge portion 74 is fitted into the rib 28 of the roof plate 2 so that the lower edge of the apron body 71 is along the bottom surface of the valley portion of the roof plate 2, and the projecting pieces 75 and the projecting pieces 76 are capped. 6 is fitted in a recess formed on the outer side of the engaging portion 61 or between the leg pieces of the cap 6 and the lower rising portion 23 of the roof plate 2 so that the end edge of the apron body 71 has the above-mentioned valley portion. It is along the rising surface on both sides of. Here, the rising surfaces on both sides of the valley are formed by the surface of the lower-side rising portion 23 of the roof plate 2 and the surfaces of the leg pieces of the cap 6. The mounting piece is placed on the cap 6, and the overlapping portion is joined by a fastener (not shown) such as a drill screw. A rivet or a bolt / nut can be used as the stopper, and in that case, a through hole 78 is formed in the mounting piece 73 as shown in FIG.

Reference numeral 8 denotes a flexible sealing member, which is arranged at a predetermined position between the apron 7 and the edge 2b of the ridge-side end 2a of the roof plate 2. The seal member 8 is made of a relatively hard rubber material such as chloroprene rubber, sponge rubber, and butyl rubber, and has a bulge 81 at its lower edge and projections 82, 83 at its edge. And further has projecting piece portions 84, 84 at both ends of its upper edge portion. Then, as shown in FIG. 3, the protruding piece portion 84 is overlaid on the cap 6, the bulge portion 81 is fitted into the rib 28 of the roof plate 2, and the lower edge of the seal member 8 is on the bottom surface of the valley portion of the roof plate 2. The protrusions 82 and the protrusions 83 are brought into close contact with each other to form a recess on the outside of the engaging portion 61 of the cap 6 or a recess formed between the leg of the cap 6 and the lower rising portion 23 of the roof plate 2. When fitted, the edge of the seal member 8 is in close contact with the rising surfaces on both sides of the valley portion of the roof plate 2. The meaning of the rising surface here is the same as that described above. The close contact means that the seal member 8 is in close contact with the bottom surface or the rising surface of the valley portion in a compressed state, or is in a non-compressed state, and the seal member 8 is a double-sided adhesive tape or an adhesive. Including the case where it is in close contact with the bottom surface or the rising surface of the valley through the above, and in any case, airtightness or watertightness is given to the contacted portion.

Reference numeral 9 is a ridge board. As shown in FIG. 1, the ridge board 9 is a metal having a width that covers the upper surfaces of the ridge-side end portions 2a, 2a of the left and right roof boards 2, 2 and covers the ridge-side end portions 2a, 2a from each other. It is made of a material, and a rib 91 protruding upward is formed at an intermediate portion (a central portion in the illustrated example) in the width direction. The left and right ends of the ridge board 9 are overlapped on the flange portion 72 of the apron 7, and the overlapping portion is joined by a fastener 92 such as a rivet. The stopper 92 is not limited to a rivet, and a drill screw may be used. However, when a rivet is used, a through hole 79 may be formed in the flange 72 as shown in FIG.

The upper edge of the seal member 8 is in close contact with a predetermined position on the back surface of the ridge plate 9 fixed to the apron 7 in this manner. That is, the seal member 8 is sandwiched between the bottom surface of the trough 2 and the ridge board 9 and is in close contact with the bottom surface of the valley and the back surface of the ridge board 9. When the seal member 8 is in close contact with the bottom surface of the valley portion or the back surface of the ridge board 9 in a compressed state or in a non-compressed state, the seal member 8 has a double-sided adhesive tape or an adhesive. In addition, including the case where it is in close contact with the bottom surface of the valley portion or the back surface of the ridge board 9, in both cases, airtightness and watertightness are given to the contacted portion.

With the configuration described above, when wind or rainwater blows up along the valleys of the roof plate 2, the apron 7 prevents the windup to some extent. Further, even if wind or rainwater that has passed through the apron is blown up further along the bottom surface or rising surface of the valley portion of the roof plate 2, it is prevented by the seal member 8. This effect is better prevented if the seal member 8 is in close contact not only with the bottom surface of the roof plate 2 and the rising surfaces on both sides thereof, as in the embodiment, but also with the back surface of the ridge board 9.

Further, since the seal member 8 is flexible and easily deforms into a shape corresponding to the shape of the roof plate 2, it is possible to relatively easily follow a complicated shape. However, when the shape of the roof plate 2 is unexpectedly complicated, caulking can be performed on the peripheral edge portion of the seal member 8 to ensure further airtightness and watertightness.

The seal member 8 may be arranged at a position close to the apron 7 or at a more spaced interval. Alternatively, the seal member 8 may be arranged on the apron 7 so as to be overlapped with each other to meet the construction conditions. And set it. In FIG. 1, the valley portion of the roof plate 2 is raised at the ridge-side end portion 2a. By doing so, even if rainwater enters the ridge-side end 2a for some reason, the rising portion 10 can prevent rainwater from entering the room.

[0022]

[Effect of the device]

 According to the present invention, even if the shape of the roof plate is complicated, since the shape of the sealing member can easily conform to the shape of the roof plate, the construction is easy and the roof shape can be freely adapted. This has the effect of being able to reliably prevent wind and rainwater from entering the building from the ridge.
