DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap receiving member for a folded-plate roof and a cap mounting structure.

[0002]

2. Description of the Related Art Conventionally, there is a construction method shown in FIG. In this method, first, as shown in (a) of the figure, ridges and valleys are alternately formed in the left and right direction on a roof base material 1 such as a beam or a purlin, and a sword-point bolt 8 is provided on the top of the ridge. The planted roof receiving frame 2 is fixed by welding or the like. Next, the folded plate 3 having the ridges and valleys alternately formed in the left-right direction is placed on the roof receiving frame 2, and the jig J is applied to the crest 3c of the folded plate 3 from above. The tip of the bolt 8 protrudes from the crest 3c of the folded plate 3 as shown in FIG. Then, as shown in FIG. 2C, the tip of the sword point bolt 8 is passed through the bolt hole 11 of the cap receiving member 10 having the bolt hole 11, and the nut 16 is used for the cap receiving member 1.
0 is tightened and fixed on the top 3 c of the folded plate 3. Finally, a cap 9 having a groove shape in cross section is fitted into the cap receiving member 10 from above with the groove opening thereof facing downward.

According to this construction method, since the peak 3c of the folded plate 3 is pierced into the tip of the sword bolt 8, the process of forming a hole for passing the sword bolt 8 in the folded plate 3 in advance is omitted.
Further, by covering the cap 9, a roof decorative effect can be obtained, and in addition, it is possible to prevent rainwater from entering from a bolt passing portion of the crest 3c of the folded plate 3 and rust generation of the sword tip bolt 8 and the nut 16 can be prevented. There is an advantage.

[0004]

However, according to the above-mentioned construction method, as shown in FIG. 7B, the tip of the sword point bolt 8 is shifted from the center position A of the crest 3c of the folded plate 3 to the position B. Often it sticks out. In such a case, a gap G (about 5 to 10 mm) is generated between the peak 3c and the cap 9, as shown in FIG.
In this case, not only the roofing finish is poor and the makeup effect is impaired, but also rainwater enters between the cap receiving fitting 10 and the peak 3c through the gap G, and further easily enters the room through the bolted portion of the peak 3c. In addition, there is a problem that the cap 9 is likely to come off due to the strong wind.

The present invention has been made in view of such a problem, and as described above, in a folded plate roof in which the peak of the folded plate is inserted into the blade bolt on the roof receiving frame side, the blade bolt is mounted on the roof. It is an object of the present invention to provide a cap receiving member and a cap mounting structure for a folded-plate roof, which can always properly attach the cap to the top of the folded plate even when the cap protrudes from the center position of the portion in the left-right direction.

[0006]

According to the present invention, a crest of a folded plate formed by alternately forming ridges and valleys in the left-right direction penetrates a sword point bolt projecting upward from a roof receiving frame. A cap receiving member disposed between the inside of the downwardly open groove having a groove-shaped cross section which is attached above the crest along the longitudinal direction thereof and the crest and receiving and supporting the cap. Target. The cap receiving member is provided on a horizontal wall portion placed on the top of the mountaintop, and downwardly from front and rear of each of a left end and a right end of the horizontal wall portion. A positioning piece that abuts, and a side wall part that has a locking part that is continuously connected upward from the front and rear positioning pieces at the left and right ends of the horizontal wall part and engages with a locked part inside the groove of the cap. And a bolt hole for passing a sword point bolt protruding from the top of the mountain is formed in a substantially central portion of the horizontal wall portion in a long hole shape elongated in the left-right direction.

In the cap receiving member, a recess is formed in a lower surface of a substantially central portion having a bolt hole of the horizontal wall portion, in which a washer and a waterproof packing, which are passed through the sword point bolt, are vertically arranged. This is preferable in that a waterproof seal can be effectively provided around the sword bolt and the bolt hole.

In the cap mounting structure for a folded plate roof according to the present invention, the crests of the folded plate formed by alternately forming peaks and valleys in the left-right direction project from a sword-point bolt projecting upward from a roof receiving frame. The waterproof packing, the washer, and the cap receiving member are inserted through the sword point bolt projecting from the top of the mountain in order from the bottom, and the cap receiving member includes a horizontal wall portion placed on the top of the mountain top, and the horizontal wall portion.

[0009]

[Function] If the tip of the sword-point bolt protrudes from the center position of the crest of the folded plate in a left-right direction, the cap holder is inserted into the bolt hole along the longitudinal direction of the bolt in the direction opposite to the direction of the deviation. By moving by the amount of shift, it is possible to match the position directly above the peak. At this time, the positioning operation for correcting the cap receiving metal fitting to the position directly above the mountaintop can be easily performed by an operation of bringing the front, rear, left and right positioning pieces into contact with the left and right outer corners of the mountaintop. When the cap receiving fitting is set in such a position, the cap is necessarily fitted on the top of the mountain by being fitted in the cap receiving fitting without any gap in the longitudinal direction.

The cap receiving member having a recess formed on the lower surface side of the substantially central portion having the bolt hole in the horizontal wall portion can stably mount the lower surfaces of the front and rear ends of the concave portion of the horizontal wall portion on the peak. By means of the washer and the waterproof packing accommodated in the concave portion, a waterproof seal can be made between the overlapping surfaces of the bolt holes of the horizontal wall portion and the peaks, and the waterproof effect around the sword bolt and the bolt hole can be enhanced.
