This window portion 44 allows the tip bolt 15 to be viewed from the front or rear side when the base 40 is placed on the beam 12 across the tight frame 13 as shown in FIG. 1(a). In addition, these notches 41a to 41d serve as marks when aligning the base 40 in the left-right direction with respect to the tip bolt 15 of the tight frame 13, and as shown in FIG. It is provided at a position that overlaps the position of the tip bolts 15, 15 in the front and back when it is in the proper position.
The distance between the left and right bearing portions 43a, 43b is approximately the same as the left and right distance between four adjacent tip bolts 15, as shown in FIG. 1(a). Each of the bearing parts 43a and 43b is provided with a hole through which the shaft 62 of the roller 60 is inserted.
Further, as shown in FIG. 1(b), when the base 40 is placed on the beam 12, the construction jig 4 is placed between the base 41 of the base 40 and the tight frame 13 on the beam 12. Clearances 50a and 50b of 5 mm are provided along the longitudinal direction of the base 41 on the front and rear sides, respectively, so that the base 41 can be shifted and moved in the longitudinal direction.

As shown in FIGS. 3 and 4, the roller 60 includes a cylindrical rotating body 61 and shafts 62 provided at both longitudinal ends thereof. The length of the rotating body 61 is longer than the width of three adjacent valleys 32 of the folded plate 3 as shown in FIG. 1(a). The roller 60 is rotatably supported by a shaft 62 inserted into holes in the bearing portions 43a, 43b of the base 40. The length of the roller 60, that is, the length of the construction jig 4, is approximately the same as the width dimension of the folded plate 3.

Next, a method for constructing a folded plate roof on the front support frame 10 and the rear support frame 20 of the simple structure 1 will be explained. Note that the construction work will be carried out by two workers A and B. Further, the construction jig 4 may be placed on either the beam of the front support frame 10 or the rear support frame 20, but in this embodiment, the construction jig 4 is placed on the beam of the front support frame 10 as shown in FIG. 12, and the folded plate 3 is sent out from the front side to the rear side and constructed.

First, as shown in FIG. 6(a), worker B places the construction jig 4 on the upper surface of one longitudinal end of the beam 12 of the front support frame 10 with the tight frame 13 straddling the front and back direction. . At this time, positioning of the construction jig 4 with respect to the beam 12 is performed as follows. As shown in FIG. 1, worker B makes sure that the legs 42a to d of the construction jig 4 do not protrude forward and backward from the top surface of the beam 12, and aligns the bearings 43a and 43b of the base 40 of the construction jig 4 in the left-right direction. The positions are aligned with the tip bolts 15, 15, respectively, and the construction jig 4 is further moved so that the tip bolts 15, 15, which are visible through the window 44 of the construction jig 4, overlap the notches 41a, 41b of the base back and forth. When the construction jig 4 is placed on the beam 12 in this manner, the axis 62 of the roller 60 becomes parallel to the longitudinal direction of the beam 12, and the roller 60 becomes freely rotatable in the front-rear direction.

Next, as shown in FIG. 6(a), worker A lifts the folded plate 3 from below the front side of the front support frame 10, and worker B lifts the folded plate 3 from the lower front side as shown in FIG. 6(b). Place it on the roller 60 of the tool 4. At this time, since the length dimension of the base 40 of the construction jig 4 is almost the same as the width dimension of the folded plate 3, the folded plate 3 is moved to the roller of the construction jig 4 in accordance with the position of the base 40 of the construction jig 4. 60, the folded plate 3 is positioned with respect to the construction jig 4, and the mounting holes 33 of the folded plate 3 and the tip bolts 15, 25 of the tight frames 13, 23 are aligned in the horizontal direction. Further, at this time, in order to prevent the folded plate 3 from wobbling in the left-right direction, it is preferable that the troughs 32 of the folded plate 3 are placed on the roller 60 at three locations as shown in FIG. 1(a).

Then, as shown in FIG. 6(c), worker B sends out the folded plate 3 to the rear, and worker A receives the rear part of the folded plate 3 and places it between the upper parts of the front support frame 10 and the rear support frame 20. A folded plate 3 is installed.

Next, as shown in FIG. 6(d), operator A inserts the four bolts 25 of the tight frame 23 of the rear support frame 20 through the four mounting holes 33 at the rear of the folded plate 3. At this time, by moving the folded plate 3 back and forth while resting on the roller 60 of the construction jig 4, the mounting hole 33 is positioned relative to the tip bolt 25.

Next, the front part of the folded plate 3 is lifted from the roller 60 of the construction jig 4, and during this time, as shown in FIG. After being moved to the other end in the longitudinal direction and retracted, the four bolts 15 of the tight frame 13 of the front support frame 10 are inserted through the four attachment holes 33 of the front part of the folded plate 3.

Then, as shown in FIG. 6(f), by repeating the steps from FIG. 6(a) to (e) for another folded plate 3, a plurality of Erect the folded plate 3. Finally, all the bolts 15 and 25 of the tight frames 13 and 23 of the front support frame 10 and the rear support frame 20 are tightened with nuts to fix all the folded plates 3, and the folded plate roof of the simple structure 1 is fixed. Construction is completed.

According to the manufacturing method of the simple structure 1 according to the above embodiment, clearances 50a and 50b are provided between the base 41 of the base 40 of the construction jig 4 and the tight frame 13 on the front side and the rear side, respectively. As a result, the construction jig 4 can be shifted and moved on the beam 12 in the longitudinal direction of the beam 12, so the construction jig 4 can be easily evacuated. Furthermore, if the dimensions of the clearances 50a and 50b are too large, the base 40 will shift back and forth during the construction work of the folded plate 3, and the axis 62 of the roller 60 will not be parallel to the longitudinal direction of the beam 12, resulting in a decrease in work efficiency. However, in this embodiment, the dimensions of the clearances 50a and 50b are not too large and are appropriately provided, so when placing the construction jig 4 on the beam 12, when sending out the folded plate 3, and when the construction jig 4 When retracting, the base 40 does not shift back and forth and the axis 62 of the roller 60 is kept parallel to the longitudinal direction of the beam 12, resulting in good workability.

Since the longitudinal dimension of the base 40, that is, the longitudinal dimension of the construction jig 4 is approximately the same as the longitudinal width of the upper surface of the beam 12, when the construction jig 4 is placed on the beam 12, the upper surface of the beam 12 By preventing it from protruding forward or backward, the construction jig 4 can be easily positioned so that the axis 62 of the roller 60 is parallel to the longitudinal direction of the beam 12, resulting in good workability.

In addition, since the spacing between the bearing parts 43a and 43b of the base 40 of the construction jig 4 is approximately the same as the horizontal spacing of four adjacent tip bolts 15, the bearing parts 43a and 43b are placed at the positions of the tip bolts 15 and 15. If the construction jig 4 is placed on the beam 12, positioning can be easily performed and work efficiency is improved.

Further, the base 40 of the construction jig 4 is provided with notches 41a to 41d at positions that overlap front and rear with the tip bolts 15, 15, and the tip bolt 15 can be visually recognized through the window 44 of the construction jig 4. By moving the construction jig 4 so that the positions of the notches 41a, 41b of the base and the tip bolts 15, 15 overlap in the front and back, the construction jig 4 can be adjusted when placing the construction jig 4 on the beam 12. Easy positioning and good workability.

Since the length dimension of the construction jig 4 is almost the same as the width dimension of the folded plate 3, by placing the folded plate 3 on the roller 60 in alignment with the position of the base 40 of the construction jig 4, The folded plate 3 can be easily positioned with respect to the construction jig 4, resulting in good workability.

Furthermore, the base 40 of the construction jig 4 has a hat-shaped cross section, and the lower surfaces of the legs 42a to 42d are in contact with the upper surface of the beam 12, so that when the folded plate 3 is placed on the construction jig 4, the construction The jig 4 does not fall back and forth, resulting in good workability.

When inserting the four bolts 25 of the tight frame 23 of the rear support frame 20 into the four mounting holes 33 at the rear of the folded plate 3, the folded plate 3 is placed on the roller 60 of the construction jig 4. Since it can be stably moved back and forth while being placed, the mounting hole 33 of the folded plate 3 can be easily positioned with respect to the tip bolt 25, resulting in good workability.

Furthermore, the construction jig 4 is lightweight and has excellent strength because the base 40 is made of steel and the rollers 60 are made of stainless steel. Furthermore, since the construction jig 4 is lightened by providing the window portion 44, the workability is good.

As described above, by the method of manufacturing the simple structure 1 having a folded plate roof according to the present invention, the erection of the folded plate 3 and the positioning of the tight frames 13 and 23 with respect to the tip bolts 15 and 25 can be performed stably even at high places. It is easy to perform and has excellent workability.

The present invention is not limited to the embodiments described above, and can be modified without departing from the gist of the present invention, and the shape, dimensions, etc. of each part of the simple structure can be changed as appropriate. For example, the material of the construction jig is not limited to the steel base and the stainless steel roller, but may be made entirely of stainless steel or entirely aluminum. Furthermore, the roller may be made of resin, or the surface of the roller may be made of stainless steel or aluminum and may be wrapped with urethane. In addition, the clearance between the base of the construction jig and the tight frame is not limited to 5 mm, but may be 3 to 10 mm, making it easier to move the construction jig in the longitudinal direction of the beam and place the folded plate on it. Any size is sufficient as long as the construction jig does not easily fall back and forth when being sent out in the front and back direction. A slippery resin component may be provided in the clearance portion of the construction jig, that is, inside the base of the base, in order to facilitate the movement of the construction jig in the longitudinal direction of the beam.
