[0007] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the front, rear, left and right are as shown in Fig. 1 to Fig. 6. Fig. 1 to Fig. 6 show an embodiment of the simple structure of the present invention, which is a carport with a folded plate roof. Fig. 2 is a front view (a) and a side view (b) of the simple structure 1, Fig. 1 is a front view (a) of the construction jig 4 placed on the beam 12 in Fig. 6(d), and Fig. 1 is a cross-sectional view taken along line II of Fig. 1(a). However, the folded plate 3 is omitted in Fig. 1(b).

[0008] As shown in Figs. 2 and 6, the simple structure 1 has a gate-shaped front support frame 10 and a rear support frame 20 erected on the ground at a distance in the front-rear direction. The front support frame 10 has a pair of left and right columns 11a, 11b, a beam 12 erected between the upper ends of the columns 11a, 11b, and a tight frame 13 attached to the upper surface of the beam 12 along the longitudinal direction. The rear support frame 20 has a pair of left and right columns 21a, 21b, a beam 22 erected between the upper ends of the columns 21a, 21b, and a tight frame 23 attached to the upper surface of the beam 22 along the longitudinal direction. As shown in Fig. 1, the tight frames 13, 23 are strip-shaped in which triangles that match the cross-sectional shape of the folded plate 3 are arranged continuously, and support the folded plate 3 from below. Sword-point bolts 15, 25 for fixing the folded plate 3 are attached to the tops of the tight frames 13, 23 so that their tips protrude upward. As shown in Fig. 5, the folded plate 3 has alternating peaks 31 and valleys 32, and weighs about 40 kg. The peaks 31 of the folded plate 3 have four mounting holes 33 at the front and rear, through which the sharp-point bolts 15, 25 of the tight frames 13, 23 of the front support frame 10 and the rear support frame 20 are inserted and fixed. The folded plate 3 is placed on the tight frames 13, 23 of the front support frame 10 and the rear support frame 20 and fixed to the sharp-point bolts 15, 25 to be erected, and a plurality of folded plates 3 are erected in a line in the left-right direction to form a folded plate roof.

[0009] The construction jig 4 for the folding plate 3 is used to facilitate the installation of the folding plate 3 between the front support frame 10 and the rear support frame 20, and to facilitate the positioning of the mounting holes 33 of the folding plate 3 relative to the point bolts 15, 25 of the tight frames 13, 23. FIG. 3 is a perspective view of the construction jig 4, and FIG. 4 is a three-sided view of the construction jig 4. As shown in FIG. 3 and FIG. 4, the construction jig 4 is composed of a base 40 with a hat-shaped cross section that is placed on the upper surface of the beams 12, 22 of the front support frame 10 or the rear support frame 20, and a roller 60 that is supported on the upper part of the base 40 so as to be rotatable in the front-rear direction. The construction jig 4 is made of steel for the base 40 and stainless steel for the rollers 60, and the weight of the construction jig 4 is about 4.2 kg. In the following, the construction jig 4 will be described in the case where it is placed on the beam 12 of the front support frame 10 as shown in FIG. 1 and FIG. 6.

[0010] As shown in Figures 3 and 4, the base 40 is composed of a base 41 that is approximately rectangular when viewed from the side, flat leg portions 42a-d that extend approximately horizontally from the lower end of the base 41 to the front and rear, and flat bearing portions 43a, 43b that rise approximately vertically from the left and right ends of the top of the base 41, respectively. The base 41 is generally H-shaped when viewed from the front, and a window 44 through which the inside of the base 41 can be seen and four notches 41a-d are provided on the upper side of the longitudinal middle part of the base 41. The window 44 allows the pointed bolt 15 to be seen from the front or rear when the base 40 is placed on the beam 12 across the tight frame 13 as shown in Fig. 1(a). The notches 41a-d also serve as markers when aligning the base 40 in the left-right direction with the pointed bolt 15 of the tight frame 13, and are provided in positions that overlap the pointed bolts 15, 15 in the front-rear direction when the construction jig 4 is in the appropriate position as shown in Fig. 1(a). The distance between the left and right bearing portions 43a, 43b is approximately the same as the left and right distance between four adjacent pointed bolts 15 as shown in Figure 1(a). Each of the bearing portions 43a, 43b is provided with a hole through which the shaft 62 of the roller 60 is inserted. Furthermore, as shown in Figure 1(b), when the base 40 is placed on the beam 12, clearances 50a, 50b of 5 mm are provided on the front and rear sides, respectively, between the base 41 of the base 40 and the tight frame 13 along the longitudinal direction of the base 41 so that the construction jig 4 can be moved on the beam 12 by shifting it in the longitudinal direction of the beam 12. The dimension of the base 40 in the front-rear direction, i.e., the dimension of the construction jig 4 in the front-rear direction, is approximately the same as the front-rear width of the upper surface of the beam 12.

[0011] 3 and 4, the roller 60 has a cylindrical rotating body 61 with shafts 62 provided at both longitudinal ends. 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 attached by inserting the shafts 62 into holes in the bearing portions 43a and 43b of the base 40. The length of the roller 60, i.e., the length of the construction jig 4, is approximately the same as the width dimension of the folded plate 3.

[0012] 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 described. The construction work is performed by two workers A and B. 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 12 of the front support frame 10 as shown in FIG. 6, and the folded plate 3 is sent from the front side to the rear side to be erected.

[0013] First, as shown in FIG. 6(a), the worker B places the construction jig 4 on the upper surface of one end of the beam 12 of the front support frame 10 in the longitudinal direction, straddling the tight frame 13 in the front-rear direction. At this time, the construction jig 4 is positioned relative to the beam 12 as follows. As shown in FIG. 1, the worker B makes sure that the legs 42a-d of the construction jig 4 do not protrude from the upper surface of the beam 12 in the front-rear direction, aligns the left-right positions of the bearing parts 43a, 43b of the base 40 of the construction jig 4 with the pointed bolts 15, 15, respectively, and further moves the construction jig 4 so that the pointed bolts 15, 15 visible through the window part 44 of the construction jig 4 overlap the notches 41a, 41b of the base in the front-rear direction. When the construction jig 4 is placed on the beam 12 in this way, 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.

[0014] Next, as shown in FIG. 6(a), worker A lifts the folding plate 3 from the front lower side of the front support frame 10, and as shown in FIG. 6(b), worker B places the rear part of the folding plate 3 on the roller 60 of the construction jig 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 folding plate 3, the folding plate 3 is positioned relative to the construction jig 4 by placing the folding plate 3 on the roller 60 of the construction jig 4 in accordance with the position of the base 40 of the construction jig 4, and the left-right positions of the mounting holes 33 of the folding plate 3 and the point bolts 15, 25 of the tight frames 13, 23 are aligned. At this time, in order to prevent the folding plate 3 from wobbling in the left-right direction, it is preferable that the valleys 32 of the folding plate 3 are placed on the roller 60 at three places as shown in FIG. 1(a).

[0015] Then, as shown in FIG. 6(c), worker B sends the folding plate 3 rearward, and worker A receives the rear part of the folding plate 3, and the folding plate 3 is erected between the upper parts of the front support frame 10 and the rear support frame 20.

[0016] Next, as shown in Fig. 6(d), worker A inserts the four mounting holes 33 at the rear of the folding plate 3 into the four pointed bolts 25 of the tight frame 23 of the rear support frame 20. At this time, the folding plate 3 is moved back and forth while resting on the rollers 60 of the construction jig 4, thereby positioning the mounting holes 33 relative to the pointed bolts 25.

[0017] Next, the front part of the folded plate 3 is lifted from the rollers 60 of the construction jig 4, and during this time, as shown in Figure 6 (e), worker B shifts the construction jig 4 over the beam 12 of the front support frame 10 toward the other end of the beam 12 in the longitudinal direction and retracts it, and then drops and inserts the four mounting holes 33 in the front part of the folded plate 3 into the four pointed bolts 15 of the tight frame 13 of the front support frame 10.

[0018] 6(f), the steps of Fig. 6(a) to (e) are repeated for another folded plate 3 to erect a plurality of folded plates 3 between the front support frame 10 and the rear support frame 20. Finally, nuts are fastened to all of the pointed bolts 15, 25 of the tight frames 13, 23 of the front support frame 10 and the rear support frame 20 to fix all of the folded plates 3, and the construction of the folded plate roof of the simplified structure 1 is completed.

[0019] According to the manufacturing method of the simple structure 1 according to the above embodiment, the clearances 50a and 50b are provided on the front and rear sides between the base 41 of the base 40 of the construction jig 4 and the tight frame 13, respectively, so that the construction jig 4 can be moved on the beam 12 by shifting it in the longitudinal direction of the beam 12, and the construction jig 4 can be easily retreated. In addition, if the dimensions of the clearances 50a and 50b are too large, the base 40 will shift forward and backward 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 reduced work efficiency. However, in this embodiment, the dimensions of the clearances 50a and 50b are not too large and are appropriately provided, so that when the construction jig 4 is placed on the beam 12, when the folded plate 3 is sent out, and when the construction jig 4 is retreated, the base 40 does not shift forward and backward, and the axis 62 of the roller 60 is kept parallel to the longitudinal direction of the beam 12, which improves workability.

[0020] Furthermore, since the front-to-rear dimension of the base 40, i.e., the front-to-rear dimension of the construction jig 4, is approximately the same as the front-to-rear width of the upper surface of the beam 12, by making sure that the construction jig 4 does not protrude from the upper surface of the beam 12 in the front-to-rear direction when placed on the beam 12, 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, thereby improving workability.

[0021] In addition, since the spacing between the bearing portions 43a, 43b of the base 40 of the construction jig 4 is approximately the same as the left-right spacing between four adjacent pointed bolts 15, by aligning the bearing portions 43a, 43b with the positions of the pointed bolts 15, 15, positioning the construction jig 4 on the beam 12 can be easily achieved, resulting in good workability.

[0022] Furthermore, notches 41a-d are provided on the base 40 of the construction jig 4 at positions that overlap with the pointed bolts 15, 15 in the front-to-back direction, and the pointed bolt 15 can be viewed through the window portion 44 of the construction jig 4. Therefore, by moving the construction jig 4 so that the notches 41a, 41b in the base and the positions of the pointed bolts 15, 15 overlap in the front-to-back direction, the positioning of the construction jig 4 can be easily performed when placing it on the beam 12, improving workability.

[0023] Furthermore, since the length dimension of the construction jig 4 is approximately the same as the width dimension of the folding plate 3, by aligning the folding plate 3 with the position of the base 40 of the construction jig 4 and placing it on the rollers 60, the folding plate 3 can be easily positioned relative to the construction jig 4, resulting in good workability.

[0024] In addition, the base 40 of the construction jig 4 has a hat-shaped cross section and the undersides of the legs 42a-d abut the upper surface of the beam 12. Therefore, when the folded plate 3 is placed on the construction jig 4, the construction jig 4 does not roll back and forth, making it easy to work with.

[0025] Furthermore, when the four mounting holes 33 at the rear of the folding plate 3 are dropped and inserted into the four pointed bolts 25 of the tight frame 23 of the rear support frame 20, the folding plate 3 can be stably moved back and forth while remaining placed on the rollers 60 of the construction jig 4, so that the mounting holes 33 of the folding plate 3 can be easily positioned relative to the pointed bolts 25, improving workability.

[0026] Furthermore, the construction jig 4 is lightweight and has excellent strength, since the base 40 is made of steel and the rollers 60 are made of stainless steel. Furthermore, the construction jig 4 is lightweight due to the provision of the window portion 44, and therefore has good workability.

[0027] As described above, the manufacturing method of the simple structure 1 having a folded plate roof of the present invention enables the erection of the folded plate 3 and the positioning work of the tight frames 13, 23 relative to the pointed bolts 15, 25 to be performed stably and easily even at high altitudes, and has excellent workability.

[0028] The present invention is not limited to the above embodiment, and can be modified within the scope of the present invention, and the shape, dimensions, etc. of each part of the simple structure can be appropriately changed. For example, the material of the construction jig is not limited to a steel base and stainless steel rollers, but may be all stainless steel or all aluminum. Furthermore, the rollers may be made of resin, and urethane may be wrapped around the surface of the stainless steel or aluminum rollers. In addition, the dimension of 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, etc., as long as the construction jig is easy to move in the longitudinal direction of the beam and the construction jig is unlikely to roll back and forth when the folded plate is placed and sent out in the longitudinal direction. And, a slippery resin part may be provided on the inside of the clearance part of the construction jig, i.e., the base of the base, to make it easy to move the construction jig in the longitudinal direction of the beam.
