[Problems to be solved by the device]

Conventionally, since it had the above-mentioned composition, it was difficult to connect the discard board 4 and the roof board material 1. That is, when connecting the both, the engaged portion 3 cannot be inserted from the slit-shaped gap on the front surface of the bag portion 9, so that the side edge of the discard board 4 and the side edge of the roof board material 1 are aligned. , The hanging piece 8 of the discard plate 4
Must be laterally fitted into the engaging portion 2 of the roof plate material 1 and the engaged portion 3 of the roof plate material 1 must be laterally fitted into the bag portion 9 of the discard plate 4. Since the fittings before and after 1 must be performed at the same time, the connecting work was difficult. Further, the water that has flowed from the gap between the side end portions of the roof plate material 1 onto the discard plate 4 is drained along the discard plate 4 onto the roof plate material 1 on the lower stage side, and is blown upward due to wind or the like. However, due to the inner surface of the bag portion 9, the rainwater is prevented from leaking over the bag portion 9 and above the waste plate 4. However, the outer peripheral surface of the engaged portion 3 of the roof plate member 1 and the end plate 4
A gap 12a is formed between the inner peripheral surface of the distal end portion of the bag portion 9 and the inner peripheral surface of the guide rib 13 of the discarding plate 4, and further, in the inner portion thereof, the engaged portion 3 has the bag portion 9a. Since the space 12b in the width direction across the entire width of the discarding plate 4 is formed between the outer surface of the engaged portion 3 and the inner surface of the bag portion 9 on the inner surface side, the space between the side end portions of the roof plate material 1 is When the water that has flowed from the gap of the above to the waste plate 4 enters the gap 12a and is blown up, the infiltrated water flows laterally in the width direction in the space 12b,
There is a risk that water may leak over the width of the discarding plate 4 from the side end of the engaged portion 3 onto the roof substrate 11 to wet the roof substrate 11 and cause it to rot. Therefore, in the conventional example, facilitating the connection between the discard plate and the roof plate material, and the water that entered between the engaged portion of the roof plate material and the bag portion overflows laterally and overflows, The technical issue is to prevent leakage.

A pair of roof plate materials are provided on the surface of the discard plate 4 in which the engaged parts 3 bent in a substantially square shape for fitting together with the engaging parts 2 are provided upright, and the guide ribs 13 are projected on both sides. 1 are arranged side by side so that the side ends are located between the guide ribs 13 and are adjacent to each other on the left and right, and the cross section is substantially cross-sectioned so as to cover the upper surface and the rear surface of the engaged portion 3 and the lower surface of the rear end portion of the roof plate 1. A watertight cover 6 which is formed in a U-shape and is separate from the discarding plate 4 is straddled between the side end portions of the engaged portions 3 of both roof plate members 1 and the watertight cover 6 is provided.
A hooking piece 6d protruding downward from the tip of the upper piece 6a is fitted to the front surface of the engaged portion 3 so as to be hooked, and a waterproof packing 5 is provided on at least the back surface and the bottom surface of the inner surface of the watertight cover 6. It is characterized in that the lever waterproof packing 5 is watertightly elastically contacted with the rear surface of the engaged portion 3 and the lower surface of the rear end portion of the roof plate 1.

[Action]

Since the present invention is configured as described above, the engaging portion 2 is hooked on the front end portion of the discarding plate 4 by inserting the front end portion of the discarding plate 4 into the engaging portion 2 of the roofing plate material 1, and The waste plate 4 and the roof plate material 1 can be connected simply by placing the side end portion of 1 on the waste plate 4, and then the waste plate 4 is separated between the engaged parts 3 of the roof plate material 1. By covering the watertight cover 6 as a body, the rear end portions of the roof plate material 1 can be easily connected to each other. Moreover, the waterproof packing 5 is provided on at least the back surface and the bottom surface of the watertight cover 6, and the waterproof packing 5 is watertightly elastically contacted with the back surface of the engaged portion 3 and the lower surface of the rear end portion of the roof plate 1. Therefore, even though the discarding plate 4 and the watertight cover 6 are formed separately, water does not leak from the gap between the discarding plate 4 and the watertight cover 6. Moreover, the watertight cover 6 having a substantially U-shaped cross section
Since the hooking piece 6d protruding downward from the tip of the upper piece 6a is fitted on the front surface of the substantially L-shaped bent engaged portion 3, the rear end of the roof plate 1 The parts can be firmly connected to each other and the waterproof packing 5 can be firmly elastically contacted to ensure a reliable watertight structure. Furthermore, the waterproof packing 5 on the inner surface of the watertight cover 6 is attached to the roof plate 1
A space is formed between the outer surface of the engaged portion 3 and the inner surface of the watertight cover 6 by elastically contacting the rear surface of the engaged portion 3 with the bottom surface thereof, and therefore, the guide ribs 13 prevent the roof plate material 1 from forming. Despite the gap 12a formed between the discarding plate 4 and the discarding plate 4, water flows in the width direction of the discarding plate 4 in the space created between the discarding plate 4 and the engaged portion 3 as in the conventional example. It is possible to prevent the water from running sideways and exceeding the width of the discard plate 4 and leaking to the outside of the discard plate 4.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Parts such as roofing board 1 are shown in FIG. That is, the lower end portion of the roofing material body 14 is folded back to the back side in a substantially U-shape to form the engaging portion 2, and the rear end portion of the roofing material body 14 is bent toward the front surface side in a substantially parallelogram shape. A substantially square-shaped engaged portion 3 is formed. The front vertical piece 3a and the rear vertical piece 3b of the engaged portion 3 are substantially parallel to each other and are inclined forward toward the lower side. Further, the upper piece 3c and the lower piece 3d are parallel to the roof material body 14, and there is a gap 16 between the lower piece 3d and the surface of the roof material body 14.
Are formed. Further, the central portion between the upper and lower portions of the roofing material main body 14 is bent very gently in a dogleg shape over the entire left and right sides. The insert piece 17 is formed in a U-shaped cross section and has a groove 18 formed on the inner peripheral side. The length of the insert piece 17 is substantially equal to the vertical dimension of the roofing material main body 14, and the central portion is adjusted to the roofing material main body 14 in a substantially It is bent in a dogleg shape. The discard plate 4 is also bent very gently in the shape of a dogleg in the center across the left and right, and the guide ribs 13 for leaking water and drainage are provided on both sides.
There are multiple vertical projections that allow water to leak downward along the roof slope without leaking water laterally. Further, the lower end edge of the discard plate 4 is bent in a substantially V shape toward the back surface side and a hanging piece 8 is provided, and at the upper end edge, a rising piece 19 is raised substantially vertically toward the front surface side. ing. The cross section of the cover 20 has a flat cutout shape having an opening at the center of the back surface, and locking pieces 21 extend inwardly from the lower surface sides of both side edges. The engaging portion 22 is bent in a substantially U shape toward the side and is formed in a U shape.
Is provided. Further, a hooking piece 23 that can be engaged with the engaging portion 2 of the upper roof sheet material 1 is provided on the upper end of the cover 20, and the hooking piece 23 is provided over the entire width of the cover 20 as shown in FIG. It is not provided, is narrower than the cover 20, and is bent upward on the front surface side. The watertight cover 6 is formed in an approximately U-shaped cross section by an upper piece 6a, a back piece 6b, and a lower piece 6c, and is inclined forward with the same inclination as the engaged portion 3 of the roof plate 1, and further, A hooking piece 6d projects downward from the front end, and a waterproof packing 5 is attached to the inner surface of the back piece 6b and the upper surface (bottom surface) of the lower piece 6c. Then, in construction, for example, each member can be individually roofed as follows. First, both side edges of the roof plate material 1 are inserted into the grooves 18 of the insertion piece 17, the insertion pieces 17 are attached to the side edges of the roof plate material 1, and the grooves 18 are arranged on the surface side edges of the roof plate material 1. Since the roof plate material 1 is roll-formed, and the bent shape of the roof plate material 1 and the insertion piece 17 in a dogleg shape varies, the insertion piece 17 is formed by the roof plate material 1.
It will be retained so that it will not fall off easily. Alternatively, the bending angle between the roof plate material 1 and the insertion piece 17 may be slightly different at the time of manufacturing so that the insertion piece 17 does not fall off when fitted to the side end of the roof plate material 1. This insert piece 17 may be attached to the roof sheet material 1 on site, but it may be attached to the side edge of the roof sheet material 1 at the time of manufacturing at the factory or at the time of shipment so that the roof sheet material 1 is sandwiched. The insertion piece 17 may be attached to the side edge of the roof plate 1 with an adhesive material. Further, since the insert piece 17 is provided separately from the roof plate material 1, roll forming of the roof plate material 1 is easy and there is no problem even if the side edge of the roof plate material 1 is cut for size adjustment. Next, the hanging piece 8 of the discard board 4 is placed on the engaged portion 3 of the lower roof board material 1 so that the discard board 4 is placed on the upper side of the lower roof board material 1 and the roof is placed on the surface of the discard board 4. The side end portions of the plate material 1 are placed and the insertion pieces 17 of the side end edges of the adjacent roof plate materials 1 are opposed to each other. At this time, as shown in FIG. 4, the hanging pieces 8 at the lower end of the discarding plate 4 are housed in the engaging portions 2 so that the engaging portions 2 of the respective upper roofing sheet materials 1 are engaged with the lower roofing sheet material 1. Engage with the joint 3. In addition, as shown in FIG. 3, a gap is provided between the insertion pieces 17 to absorb expansion and contraction of the roof plate material 1 due to temperature change. After that, the hooking piece 6d is hooked on the engaged portion 3 so as to straddle between the engaged portions 3 of the roof plate materials that are adjacent to each other on the left and right, as shown in FIG. A watertight cover 6 is fitted to the rear end of the plate material 1 from the rear. The waterproof packing 5 on the inner surface of the watertight cover 6 fitted between the engaged portions 3 makes watertight elastic contact with the back surface of the engaged portion 3 and the lower surface of the rear end portion of the roof plate 1. Therefore, the engaged portions 3 are connected to each other by the watertight cover 6, the gap between the engaged portions 3 is covered by the watertight cover 6, and water can be prevented from being blown up from this gap. Moreover, since the waterproof packing 5 is elastically contacted between the discard plate 4 and the watertight cover 6, a space is prevented from being formed between the outer surface of the engaged portion 3 and the inner surface of the watertight cover 6, and thus the guide is provided. A gap 12a is formed between the roof plate 1 and the waste plate 4 by the rib 13.
Despite the formation of water, water runs laterally in the width direction of the discard plate 4 in the space created between the discard plate 4 and the engaged portion 3 as in the conventional example, and the width of the discard plate 4 is reduced. It is possible to prevent water from leaking over the roof substrate 11 outside the discard plate 4. Next, the cover 20 is slid and covered between the insertion pieces 17 at the ends of the roof plate 1 which are opposed to each other on the surface of the discard plate 4,
As shown in FIG. 5, insert the locking piece 21 of the cover 20 into the insertion piece 17
The roof plate materials 1 can be connected to each other by being fitted into the groove 18 of the above, and the U-shaped engaging portion 22 of the cover 20 is fitted to the surface of the engaging portion 2. Further, the hooking piece 23 on the upper end of the cover 20 can be engaged with the engaging portion 2 of the upper roof plate material 1 as shown in FIG. FIG. 6 shows another example of the present invention, in which the lower piece 3d of the engaged portion 3 is extended toward the front end side. FIG. 7 shows a further example of the present invention, which uses a cover 20 integrated with the insertion piece 17. That is, the insertion pieces 17 for inserting the side edges of the roof plate material 1 are integrally provided on both sides of the back surface of the cover 20, and after the roof plate material 1 is arranged on the discard plate 4, the cover 20 is slid to insert the insertion pieces. The side edge of the roof plate material 1 is inserted into the inside 17.

According to the present invention, the engaging part is hooked on the front end of the discarding plate by inserting the front end of the discarding plate into the engaging part of the roof plate material.
By simply placing the side edge of the roof plate on the discard plate, the discard plate and the roof plate can be connected. After that, the watertight cover separated from the discard plate between the engaged parts of the roof plate. By covering with the cover, the rear end portions of the roof plate material can be easily connected to each other. Moreover, at least the back surface and the bottom surface of the watertight cover inner surface are provided with waterproof packing, and since this waterproof packing is watertightly elastically contacted with the back surface of the engaged portion and the lower surface of the rear end of the roof plate, it is discarded. Even though the plate and the watertight cover are separated, water does not leak from the gap between the discard plate and the watertight cover. Further, the waterproof packing on the inner surface of the watertight cover prevents the occurrence of a space between the outer surface of the engaged portion and the inner surface of the watertight cover by elastically contacting the back surface of the engaged portion of the roof plate from the bottom surface,
Therefore, although the gap is formed between the roof plate material and the discard plate by the guide rib, the width of the discard plate does not pass through the space created between the discard plate and the engaged portion as in the conventional example. It is possible to prevent the water from running sideways and exceeding the width of the discarding plate to leak to the outside of the discarding plate. Moreover, since the hooking piece protruding downward from the tip of the upper piece of the watertight cover having a substantially U-shaped cross section is fitted so as to be hooked on the front surface of the engaged portion bent in a substantially R-shape, The rear end portions of the roof plate material can be firmly connected to each other and the waterproof packing can be firmly elastically contacted with the engaged portion to ensure a reliable watertight structure. Further, the waterproof packing also improves the airtightness between the engaged portion of the roof plate material, the watertight cover, and the discard plate. And since the watertight cover is a separate body from the discard plate, it can follow the expansion and contraction of the roof plate material,
It is possible to secure reliable watertightness and airtightness.
