[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folded roof of a type in which adjacent roof materials are press-fitted with clips and caps to a roof base material via a tight frame with clips and caps.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open No. 3-241148 discloses a structure for mounting a roof member of this type. There, the joint walls of adjacent roof materials are joined and supported on a gate-shaped tight frame fixed on the roof base material, and a clip is press-fitted to this joint from above, and the longer The roof material is joined and fixed by press-fitting the cap from above.

[0003] Such a roof-fitting structure of the press-fitting type has a relatively low load-bearing and wind-resistant strength as compared with a work form in which the joints of the roof-material are wound or bolted together. Applications were limited to folded roofs with light loads. However, because the workability on site is by far the best, the application to folding roofs using large roof materials, such as gymnasiums and large warehouses, is being attempted. Roof base materials such as beams and purlins in large structures such as gymnasiums are often installed with their upper surfaces horizontal regardless of the roof slope. Conventionally, a roof with a predetermined roof slope is roofed on such a horizontal roof base material.In the past, a slope base inclined at the same angle as the roof slope was welded to the roof base material, and a tight frame was bolted on this slope base. Was. By the way, in the form in which the joining wall of the roof material is wound and fixed with the hanging member as the core, the hanging member is fastened to the tight frame with one bolt, and the hanging member is tilted around the bolt, so that the roof It corresponds to the change of the gradient.

[0004]

As described above, in the work mode in which the inclined base is welded to the horizontal base material of the roof and the tight frame is mounted on the inclined base as described above, extra work is required for the preparation work. The good workability, which is a feature of the joining method, cannot be fully utilized.

[0005] If there is a variation in the welding position of the inclined table, the roof gradient varies in the longitudinal direction of the roof material, and it is also difficult to correct it after welding. Therefore, the construction quality of the folded roof is likely to deteriorate. Even when the roof base material is inclined in advance in accordance with the roof gradient, the roof gradient also varies due to variations in the positions of the beams and the purlin or the inclination angle.

Accordingly, an object of the present invention is to fix a tight frame on a horizontal roof base material and to lay a folded roof with a predetermined roof gradient by omitting a preparation work such as welding of a sloping base, thereby reducing the number of preparations. An object of the present invention is to provide a roof material mounting structure of a press-fitting type, which can easily mount a roof material. Another object of the present invention is to improve the construction quality of folded roofs even when there are variations in the position or angle of the roof base material or tight frame, etc. Providing mounting structure.

[0007]

The folded roof according to the present invention has a wing piece 3 having a pair of left and right receiving walls 20 mounted on an upper part of a tight frame 2 fixed to a roof base material 1. The retaining wall 14 provided on the joint wall 11 of the adjacent roof member 4 is assembled to the receiving wall 20 in a state of engaging with the receiving wall 20 from the lower surface side. On the wing piece 3, the pair of joining walls 11 are formed by a clip 23 and a cap 24 which are press-fitted to these from above,
Or, when not using the clip 23, the cap 24
Then, they are inseparably integrated. Then, the entire wing piece 3 is fixed to the tight frame 2 with the fastener 9 so as to be tiltable along the joining line of the roof material 4. At the lower part of the wing piece 3, receiving seats 21 are provided on both right and left sides, and the hanging wall 1 is provided.
4 and the shoulder wall 12 of the roof member 4 located below the seat 2
One is to support.

[0008]

When the wing piece 3 for engaging the retaining wall 14 of the joint wall 11 is provided above the tight frame 2, the wing piece 3 is fixed to the tight frame 2 with the fastener 9 so as to be tiltable. Therefore, even if the roof base material 1 for fixing the tight frame 2 is installed horizontally, one roof material 4 is engaged with the wing pieces 3 and the group of wing pieces 3
The roof slope of the roof material 4 can be set to a predetermined value only by inclining along the slope line of the above. At this time, even if there are variations in the fixed position of the tight frame 2 and the position and orientation of the roof base material 1, the variations can be absorbed by the tilting blade pieces 3 and the roof gradient can be made uniform. After the tilting posture of the wing piece 3 is determined by assembling one roof member 4, the fastener 9 is tightened to fix the posture, and then the other roof member 4 is assembled, and then the clip 2
3 and the cap 24 or the cap 24 are sequentially press-fitted.

[0009]

According to the present invention, the wing piece 3 is attached to the tight frame 2 so as to be rotatable in a direction along the joining line of the roof material 4, and the wing piece 3 is tilted so that the roof material 4 has a predetermined roof gradient. Can be joined. Therefore, even in a gymnasium, a large warehouse, or the like, even when the roof base material 1 such as a beam or a purlin is installed horizontally, the roof material 4 can be installed in a similar manner to the conventional press-fit type roof material mounting structure. The roof can be roofed and a predetermined roof slope can be obtained, and the labor and time required for the construction can be reduced, and the construction cost can be reduced. Since the inclination degree of the wing pieces 3 can be changed for each tight frame 2, the inclination degree of the wing pieces 3 is adjusted even if the position or angle of the roof base material 1 or the tight frame 2 varies. By doing so, variations can be absorbed and the roof gradient can be made uniform, and the folded roof can be finished in a more advanced construction state. The shoulder wall 12 of the roof material 4 is attached to the seat 2 of the wing piece 3.
In the form supported by 1, the strength of the roof member 4 can be improved by receiving a load from above with the seat 21.
