【Example】

 An embodiment of a roof structure having a cap member of the present invention will be described in detail below with reference to the drawings. Fig. 1 shows a cross section of the roof structure. Reference numeral 1 is a base material for a purlin, etc., 2 is a folded roof, and this folded roof 2 is a roof plate material with a heat insulating material adhered to the back surface (folded roof plate). 3 is vertically sloping at a constant slope, and the clip 5 is press-fitted to both joints 4 and 4 so that the joints 4 and 4 provided at both ends in the width direction are integrally joined to each other. Further, a cap member 6 having a heat insulating material adhered to its back is fitted to the clip 5 at a locking portion 3A provided at the joint portion 4 of the origami roof 2 so that a folding process is not required. , The roof plate materials 3, 3 are integrally joined. A gutter-shaped portion 4A is provided at the upper end of the joint portion 4 of the origami roof 2.

On the other hand, a roof receiving frame 7 for supporting both joints 4 and 4 is erected on the purlin 1 by bolt fastening or the like, and the above-mentioned clip 5 is an engaging portion of the roof receiving frame 7. Corresponding to the position of 7A, the engaging portions 3A, 3A of both joint portions 4, 4 are press fitted.

A mounting member 8 is fixed to the cap member 6 in a position corresponding to the positions of the roof receiving frame 7 and the clip 5, and a ridge board 9 which is a roof structure is provided above the mounting member 8. It is mounted and fixed by fastening bolts 16.

The mounting bracket 8 has a flat mounting base 10 for mounting and fixing the ridge board 9 thereon (see FIG. 2), and left and right side wall parts hanging from both sides of the mounting base 10. Engaging claws 14A and 14B that engage with engaging step portions 13 and 13 formed on both side portions 12 and 12 of the cap member 6 are bent inwardly at lower ends of 11A and 11B. On one side wall portion 11A, a tightening bolt 15 for pressing the side portion 12 above the engagement step portion 13 of the cap member 6 is screwed.

With such a configuration, the side wall of the mounting member 8 is attached to the engaging step portions 13 and 13 provided on both side portions 12 and 12 of the cap member 6 which is covered by the joint portion 4 of the origami roof 2. The fitting claws 14A and 14B formed on the portions 11A and 11B are engaged with each other so that the mounting metal fitting 8 is fitted to the cap member 6 and the engaging step of the cap member 6 with the tightening bolt 15. By tightening so that the side portion 12 above the portion 13 is pressed, the mounting metal fitting 8 can be stably fixed to the cap member 6.

In such a fixed state, the engaging claws 14A and 14B of the mounting member 8 are engaged with the engaging step portions 13 of the both side portions 12 and 12 of the cap member 6, and the engagement is further improved by bolting. Since it is a tie, both side portions 12 and 12 of the cap member 6 are in close contact with the joint portions 4 and 4 of the origami roof 2, and due to the load of the ridge board 9, there is also snowfall. At the same time, not only can the side portions 12 at both ends thereof be prevented from coming off the joint portions 4 and 4, but also negative pressure can be dealt with. Further, by appropriately setting the plate thickness of the mounting bracket 8, it is possible to improve the support rigidity of the rooftop structure 9 such as a ridge board.

In order to construct a roof structure having such a cap member, first, a roof support frame 7 is erected and fixed on the purlin 1 by bolt fastening (or welding), and then both roof plate members are mounted on the roof support frame 7. The joints 4 and 4 of 3 and 3 are placed on top of each other, but they are brought into contact with each other, and the clip 5 is press-fitted and mounted thereon. The required number of clips 5 may be attached in correspondence with the position of the roof receiving frame 7 (see FIG. 3).

Next, the cap member 6 is fitted in the longitudinal direction of the joint portion 4 so as to be pushed. Then, the insides of both engaging step portions 13, 13 of the cap member 6 are engaged with the lower end edges of the respective clips 5, so that the cap member 6 is fitted tightly on the joint portions 4, 4 to the outside. Be covered.

Then, the engaging claws 14A, 14B of the mounting member 8 are engaged with the engaging step portions 13, 13 of the cap member 6 at the portions corresponding to the roof receiving frame 7 and the clip 5 described above. Then, the mounting metal fitting 8 is fitted to the cap member 6, and is tightened with the tightening bolt 15 so as to press the side portion 12 above the engaging step portion 13, and the mounting metal fitting 8 is capped. It can be fixed to the member 6 in a strong and stable state.

Thereafter, the ridge board 9 is mounted on the mounting base 10 of the mounting bracket 8 and the bolts 16 are fastened (see FIG. 2), whereby the assembling work is completed. In the state in which the ridge board 9 is assembled, the bolt 16 is set in the void 20 at a position separated from the cap member 6 (see FIG. 1), and it is necessary to make a hole in the roof board material 3. Since it does not have rainwater, the rain is well maintained and problems such as water leaks can be avoided. When the roof structure 9 is fixed between the base 10 and the cap member 6 with the fastener (bolt 16), the tip of the fastener can be exposed in the void 20.

As the bolt 16 described above, a sword bolt can be used, and welding can be adopted instead of these bolts. In addition to the ridge board, the rooftop structure 9 may be a snow frame, a solar water heater, a TV antenna stand, an advertising board, or the like. It goes without saying that it can be stably mounted on the folded roof 2 via the mounting bracket 8. If the platform 10 is mounted on the cap member 6, the roof structure 9 can be mounted in a stable state.

[Effect of device]

 As described above, according to the present invention, the lower end edge of the side wall portion of the fitting having the flat mount portion on the upper side is engaged with the engaging step portions provided on both sides of the cap member. Since the claw is formed and a fastening bolt for pressing the side portion above the engagement step portion of the cap member is screwed on one side wall portion thereof, the engagement step portion of the cap member is formed. In addition, by engaging the engaging claws of the mounting bracket with the mounting bracket to the cap member and tightening the bolts, the mounting bracket can be stably fixed to the cap member with good workability. You can

In the fixed state, the engaging claws of the mounting bracket engage with the engaging stepped portions of the cap member, and the tightening of the bolts makes the engagement tighter. Not only can it withstand loads such as snowfall, but it can also handle negative pressure. In addition, the support rigidity of the rooftop structure can be improved by appropriately setting the plate thickness of the mounting bracket.

Since the rooftop structure such as the ridge board is supported by the cap member via the mounting bracket, and the cap member is clamped and fixed by the mounting bracket to the origami roof plate, mutual thermal expansion and contraction occurs. Since it is assembled so that it can absorb the difference between the cap member and the folded roof, there will be problems such as screw breakage due to thermal expansion and contraction or damage and deformation of the cap member and folded roof, etc. Is avoided and the durability of the roof structure is improved.
