DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing a folded plate 1.
Is a method of forming a fixed roof on a base material 11 made of, for example, a C-shaped steel in order from one side (see FIG. 2).

The folded plate 1 is elongated in the front-rear direction and has a long shape corresponding to the length from the ridge to the eave, and has rising portions 3 and 4 rising diagonally upward and outward on both left and right sides of a horizontal portion 2 having a predetermined width. are doing. A lower engaging portion 5 is formed at the tip of one of the rising portions 3 (right side in the drawing), and an upper engaging portion is formed at the tip of the other rising portion 4 (left side in the drawing). The part 6 is formed.

The lower engaging portion 5 and the upper engaging portion 6 are mutually engaged between adjacent folded plates 1, and the upper engaging portion 6 is engaged with the lower engaging portion 5. , So as to cover the entirety from above.

That is, the lower engaging portion 5 has two right and left engaging edges, a first engaging edge 5a and a second engaging edge 5b, which are equally formed on the left and right. The first engagement edge 5a on the left side of the drawing is formed by rising slightly from the stepped portion 5c that extends horizontally outward from the rising portion 3 and then slightly winding downward. A flat portion 5d is formed after extending further obliquely upward from the first engaging edge 5a, and a vertically elongated gutter-shaped fixing portion 5e is formed from the flat portion 5d.

The second engaging edge 5b on the right side of the drawing is formed from the upper end of the fixing portion 5e via a flat portion 5d so as to be symmetrical with the first engaging edge 5a with the fixing portion 5e interposed therebetween. Second
The distal end of the engaging edge 5b is wound downward to form a reinforcing portion 5f, thereby stabilizing the form. This is to prevent the article from being deformed by colliding with something during transportation.

The fixing portion 5e has a structure for fixing to the base material 11, and is formed to hang down to a height corresponding to the horizontal portion 2.

The above-mentioned upper engaging portion 1 is provided with the above-mentioned lower engaging portion 5
A second engagement edge 6b similar to the first engagement edge 5a of the lower engagement portion 5 is formed at the tip of a step portion 6a that is slightly larger than the rising portion 4 and extends horizontally outward from the rising portion 4. The first engagement edge 6c is formed at a position facing the first engagement edge 6c. A concave portion 6e is formed in the top portion 6d at the upper end connecting the first engaging edge 6c and the second engaging edge 6b along the length direction (front-back direction).

The concave portion 6e serves to reinforce the top portion 6d itself and to prevent a mutual shift in the left-right direction when engaged with the lower engaging portion 5. At the time of engagement, the width and depth of the recess 6e are set so as to come into contact with the corner of the upper end of the fixed portion 5e in the lower engagement portion 5. Although the concave portion 6e has tapered portions on the left and right sides as shown in the figure from the point of design, the engagement between the lower engaging portion 5 and the upper engaging portion 6 can be favorably performed by mutual material elasticity as described later. Therefore, it may be formed vertically.

The middle recess 2a of the horizontal portion 2 is
This is for improving the strength and the design feeling.

In order to form a folded plate roof using the folded plate 1 configured as described above, first, as shown in FIG. The fixing portion 5e formed on the side engaging portion 5 is directly fixed with the drill screw 12. A drill screw may be screwed into the inner bottom surface of the fixing portion 5e from above. Since the fixing portion 5e hangs down to a position corresponding to the height of the horizontal portion 2, it is sufficient to screw it tightly until the drill screw 12 is completely tightened. I can do it.

Then, the upper engaging portion 6 of another folded plate 1 is engaged with the lower engaging portion 5 of the folded plate 1 thus fixed, and the folded plates 1 are connected to each other. This engagement is performed by the lower engagement portion 5.
The first engagement edge 6 of the upper engagement portion 6 with respect to the first engagement edge 5a
c, the second engagement edge 6b of the upper engagement portion 6 is performed with respect to the second engagement edge 5b of the lower engagement portion 5 by utilizing the material elasticity of each of the engagement portions 5 and 6.

At this time, as shown in FIG. 3, the lower surface of the top surface 6d of the upper engaging portion 6 contacts the flat portion 5d of the lower engaging portion 5. Thereby, a load from above can be favorably supported.
This means that the fixing portion 5e is formed in a gutter shape,
It is also promoted by supporting with one piece. At the same time, the lower surface of the concave portion 6e formed in the top portion 6d of the upper engaging portion 6 comes into contact with the upper end corner of the fixing portion 5e formed in the lower engaging portion 5. In other words, the lower surface of the concave portion 6e fits into the upper end of the fixing portion 5e. For this reason, there is no shift in the left-right direction, and a good fixed state can be obtained.

Further, since the fixing portion 5e is formed in a gutter shape as described above, the lower engagement portion 5 has elasticity in the left-right direction. That is, the first engagement edge 5a and the second engagement edge 5
b is easily elastically displaced in the left-right direction. For this reason, the work of engaging the upper engaging portion 6 can be easily performed. However, since the concave portion 6e formed in the top portion 6d of the upper engaging portion 6 fits into the upper end of the fixing portion 5e of the lower engaging portion 5 as described above, a negative pressure is applied after the engagement. In this case, the fixed portion 5e is not deformed to be narrow, and the fixed state can be firmly maintained.

If the rising angle of the lower engaging portion 5 is set lower than that of the upper engaging portion 6 as shown in the figure, the drainage space 7 can be formed, and there is no danger of rain leakage. You can get a folded roof.

The formation of the folded plate roof can be performed simply by repeating the three operations of placing the folded plate 1 on the base material 11, fixing it with the drill screw 12, and engaging another folded plate 1 as described above. Good. In other words, a conventional tight frame is not required, and neither blacking work nor welding work required for fixing is required, and the work can be performed easily and smoothly. Moreover,
Since the lower engaging portion 5 and the upper engaging portion 6 of the folded plate 1 are adjacent to each other and engage with each other, it is not necessary to tighten the folding plate 1 as in the case of using the suspension. The connection work is also very easy. Furthermore, since a tight frame is not required, the number of parts is reduced, and the cost can be reduced.

The fixing portion 5e is directly fixed to the base material 11 with a drill screw 12, but the upper portion of the fixing portion 5e is covered with the upper engaging portion 6 in a cap shape. No water leaks from the drilled holes. Therefore, no packing is required.

FIG. 4 shows an example in which the rising of the lower engaging portion 5 from the first engaging edge 5a and the second engaging edge 5b to the flat portion 5d is curved. With this configuration, the elasticity of the first engagement edge 5a and the second engagement edge 5b can be enhanced, and the drainage space 7 can be formed larger.

FIG. 5 shows a fixing portion 5 formed on the lower engaging portion 5.
This shows an example in which e is formed shallow. The folded plate 1 thus formed is fixed by interposing a spacer 13 between the fixing portion 5e and the base material 11, as shown in FIGS. The spacer 13 may be a hollow metal pipe. Inexpensive. In this way, the material required to obtain the folded plate 1 can be reduced, and the cost can be further reduced. As the spacer 13, besides a hollow metal pipe,
For example, an appropriate inexpensive member such as a metal plate bent in a U shape may be used.

FIG. 8 shows an example in which two fixing portions formed on the lower engaging portion 5 are formed. That is, the first fixing portion 5g having a shallow gutter-like shape is formed between the first engagement edge 5a and the second engagement edge 5b as in the folded plate 1 shown in FIG.
An L-shaped second fixing portion 5h extends from the tip of the second engagement edge 5b. The lower end of the second fixing part 5h is the first fixing part 5g.
The drill screw 12 screwed from the first fixing portion 5g is screwed into the base material 11 through the lower end of the second fixing portion 5h. At this time, the drill screw 12 has a length equal to the length at which the screwing is completed in a state where the distance between the first fixing portion 5g and the second fixing portion 5h is maintained in a predetermined state.
The one in which a is formed is used. This is because there is no overtightening or undertightening.

At the time of fixing the folded plate 1, two of the first fixing portion 5g and the second fixing portion 5h are fixed by the drill screw 12,
The load is supported from above by the drill screw 12 and the L-shaped second fixing portion 5h, and the drill screw 12 also counters negative pressure. In addition, due to the presence of the L-shaped second fixing portion 5h, it is resistant to a load in the left-right direction. In addition, the spacer can be eliminated, and the material of the folded plate 1 can be reduced.

FIG. 9 shows a fixing portion 5 formed on the lower engagement portion 5.
In this example, e is extended from the first engagement edge 5a as in the previous embodiment, and then the second engagement edge 5b is formed not symmetrically with the first engagement edge 5a. That is, the second of the fixing portion 5e
The upper end on the side of the engaging edge 5b is the second engaging portion 6b of the upper engaging portion 6.
The second engagement edge 5b is formed by winding outward from this position downward. Further, a receiving portion 5i bent in an L-shape is formed below this. The step 6a of the upper engaging portion 6 is supported by the receiving portion 5i. If the distal end side of the receiving portion 5i is slightly upwardly urged as shown by the imaginary line, positive and strong fixation can be expected between the second engaging edge 5b and the receiving portion 5i.

FIG. 10 shows the fixing portion 5e formed on the lower engaging portion 5 after extending from the first engaging edge 5e via the flat portion 5d as in the previous embodiment, as shown in FIG. The second engaging edge 5b is formed from the middle like the folded plate 1. An example is shown in which a flat portion 5j extending upward inward is formed as it is raised upward. When formed in this manner, it is possible to impart a biasing force to a portion beyond the second engagement edge 5b to obtain a stronger fixed state. That is, the second engaging edge 5b is formed so as to jump upward from the second engaging edge 5b as indicated by a virtual line. When the upper engaging portion 6 is engaged, the tip is pushed down from the second engaging edge 5b against the urging force, and the fixed state shown by the solid line is obtained. At the time of this engagement, the internal pressure is high and the state is tight, so that a firm fixed state is obtained. In addition, the flat portions 5d and 5j support the top portion 6d of the upper engaging portion 6 and abut against the lower surface of the concave portion 6e of the upper engaging portion 6.
