Description

The present invention relates to a method for constructing a folded roof.

[Outline of Invention]

An outer seam and an inner seam are formed on the ridges at both ends of the origami shingles, the openings of both are oriented in the same direction, and the tip of the outer seam wraps the tip of the inner seam. , With the roof plate slightly tilted, engage the outer seam with the inner seam of the existing roof plate adjacent to it, and then rotate the roof plate to form on the back surface of the inclined part of the roof plate. It is a construction method of a folded plate roof in which the joint part is engaged with the step part of the tight frame, there is no need to tighten the seam, and the engagement of the seam part and the fixing of the roof plate to the tight frame are performed once. In addition, the assembly is easy, the workability is good, and the time required for the construction can be shortened.

[Conventional technology]

Conventionally, in the method of constructing a folded roof, as shown in FIG. 4, the engaging portion 3d formed on the back surface of the folded roof plate 3 is engaged with the claw portion 2b of the tight frame 2 so that the bolt is tightened. A so-called boltless construction method is known in which the roof plate is fixed without using the. However, this method has a drawback in that workability is poor because it takes time and effort to engage the roof plates with the tight frame and then tighten and join the joints of the roof plates adjacent to each other.

[Problems to be solved by the invention]

An object of the present invention is to remedy the above-mentioned drawbacks of the conventional device, and it is not necessary to tighten the seams, and the seams can be connected and the roof plate can be fixed to the tight frame at one time. Is to provide a simple folding roof construction method.

[Means for solving problems]

In order to achieve the above object, the folded roof of the present invention has a roof frame composed of a mountain portion and a valley portion which are alternately formed and an inclined portion connecting both of them, which are continuously arranged on a tight frame so that both ends of the roof plate are connected. In a folded roof that joins the ridge formed on the mountain part of the roof with the ridge of the adjacent roof plate, engages the step on the slope of the tight frame and the back of the slope of the roof. Each of the parts is formed, the opening of the outer seam and the opening of the inner seam are oriented in the same direction, and the tip of the outer seam is in a shape including the tip of the inner seam, and the roof plate is slightly inclined. In this condition, the outer seam is engaged with the existing inner seam of the existing roof plate, and then the roof plate is rotated to engage the engaging part of the roof plate with the step of the tight frame. ing.

[Action]

By doing so, with the roof plate slightly tilted, the outer seam part is engaged with the inner seam part of the existing existing roof plate and simply rotated to move the seam part together. The roof plate and the roof frame can be fixed to the tight frame at the same time, and there is no need to tighten the seams.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings. 1 and 2 are front views showing the construction procedure.

Tight frame 2 with stepped portions 2a on both sides of the slope,
As well known, they are fixed on the beam 1 and arranged at predetermined intervals. On the back surface of the inclined portions 3b on both sides of the origami plate 3 in which a mountain portion 3a, an inclined portion 3b and a valley portion 3c are formed by bending one iron plate (at a position facing the step portion 2a of the tight frame). ) Engagement portions 3d are formed respectively.

Further, an outer seam 3e and an inner seam 3f are formed in the mountain portions 3a at both ends of the roof plate 3 with their openings facing the same direction. The tip of the outer seam 3e is shaped so as to wrap around the tip of the inner seam 3f. Therefore, when engaging the seam 3e and 3f of the roof plates 3 adjacent to each other, the first As shown in the figure, one roof plate 3 is tilted and the tips of the seams are hooked together, and then the roof plate 3 is rotated to fit both seams.

Next, the construction procedure will be described.

As shown in FIG. 1, the roof plate 3 to be assembled is tilted, and the outer end of the roof portion 3e is hooked on the inner end of the existing adjacent roof plate 3 to the tip of the seam portion 3f. ,
When the roof plate 3 is rotated to the state shown in FIG. 2 while the two seams are fitted, the outer seam 3c and the inner seam 3f are completely fitted together and the roof plate urface engaging portion. 3d engages with the step portion 2a of the tight frame 2. Since the engagement between the engagement portion 3d and the stepped portion 2a is performed by the weight of the roof plate 3 when the roof plate 3 is rotated, the assembling work is extremely simple.

After the assembly of one sheet is completed, the next roof plate 3 may be assembled in the same procedure, and thereafter, may be sequentially and repeatedly assembled.

The shape of the roof plate 3 is not limited to the one having the valley portion 3c as in the above-described embodiment, and for example, one having two valley portions 3c as shown in FIG. 3 or further three or more. Those equipped with can be used as well.

〔The invention's effect〕

As described above, the construction method of the folded roof of the present invention is
With the roof plates slightly tilted, the outer seams are engaged with the existing existing inner seams, and the rotation of the adjacent roof plates is performed by a simple operation of rotating. The roof parts can be joined and fixed to the tight frame at the same time, and the roof plate can be stably rotated around the tip of the outer seam, so there is no need to apply strong force to the roof. The engaging part of the plate can be easily and surely engaged with the step part of the tight frame, and the subsequent tightening is not necessary, and the roof plates can be assembled in sequence in a good procedure, so the work is simple The properties are improved and the time required for construction can be significantly shortened.
