Summary of the Invention

Problems to be Solved by the Invention

[0004] In order to install the movable work platform so that it can move on the ground, it is necessary to install rails on the ground, and external construction cannot be started until the roofing work is completed. In addition, when the building is tall, the movable work platform itself becomes large-scale. An object of this invention is to solve such problems, for example.

Means for Solving the Problems

[0005] The work platform is movably installed on a first rail and a second rail installed in parallel with the first rail. The work platform has a forming machine mounting table for mounting a folded-plate forming machine. The forming machine mounting table is arranged from directly above the inter-rail region sandwiched between the first rail and the second rail to directly above the first outer region outside the first rail. The work platform may further have an uncoiler mounting table for mounting an uncoiler. The uncoiler mounting table may be arranged directly above the inter-rail region. The uncoiler mounting base may be positioned above the molding machine mounting base. The work platform may further include a cutting machine mounting platform for mounting a cutting machine. The cutting machine mounting platform may be positioned directly above the rail-to-rail area. The cutting machine mounting base may be positioned above the molding machine mounting base. The roof construction method involves installing the first rail and the second rail on the rooftop floor of the building, installing a work platform according to any of claims 1 to 5 on the first rail and the second rail, installing a corrugated sheet metal forming machine on the work platform, and forming a corrugated sheet metal roof on the rooftop using the corrugated sheet metal forming machine. [Effects of the Invention]

[0006] Since the molding machine mounting platform is positioned from directly above the rail-to-rail area to directly above the first outer area, corrugated metal roofs can be formed on the rooftop even if the rail spacing is narrower than that of a corrugated metal roofing machine. This means that if there are parts of the building's rooftop floor that do not have a roof, such as a driveway, rails can be installed there, eliminating the need to install rails on the ground and allowing exterior construction work to be carried out in parallel with roof construction. In addition, the height of the work platform is lower compared to when rails are installed on the ground, which helps to reduce costs. [Brief explanation of the drawing]

[0016] The trolleys 13a to 13l are attached to the underside of the frame body 12. The trolleys 13a to 13f move along rail 81a (see Figure 6). The trolleys 13g to 13l move along rail 81b. This allows the entire work frame 10 to move in the ±X direction along rails 81a and 81b. The bogie 13a is attached to the -X end of the beam section 21a.

[0017] The molding machine mounting section 15 is provided on a surface formed by beam sections 23a to 23n for mounting the corrugated sheet metal molding machine 84 (see Figure 6). The molding machine mounting section 15 includes, for example, a scaffolding board 51, handrails 52a and 52b, and molding machine mounting tables 53a to 53d. The scaffolding board 51 is a platform on which workers can work. The scaffolding board 51 is a rectangular board that is approximately perpendicular to the ±Z direction and is positioned in the area between the beam sections 23e~23i and beam sections 23j~23n. The handrails 52a and 52b prevent workers from falling while working on the scaffolding board 51. Handrail 52a is provided at the -X end of the scaffolding board 51. Handrail 52b is provided at the +X end of the scaffolding board 51.

[0018] The molding machine mounting bases 53a to 53d are elongated in the ±X direction, and the sheet metal forming machine 84 is placed on them. The molding machine mounting base 53a is positioned directly above the beam section 23a. In other words, the molding machine mounting base 53a is located on the -Y side of directly above the rail 81a. The molding machine mounting base 53b is positioned directly above the beam section 23b. 53b It is located directly above rail 81a. The molding machine mounting base 53c is positioned directly above the beam section 23c. That is, the molding machine mounting base 53c It is located to the +Y side of directly above rail 81a and to the -Y side of directly above rail 81b. The molding machine mounting base 53d is positioned directly above the beam section 23d. That is, the molding machine mounting base 53d teeth, +Y side of directly above rail 81a and -Y side of directly above rail 81bIt is located in [location]. Because the molding machine mounting bases 53a to 53d are arranged in this manner, the corrugated sheet metal forming machine 84 can be stably mounted even if the length of the corrugated sheet metal forming machine 84 is longer than the distance between the rails 81a and 81b.

[0019] The coil mounting section 16 is provided on a surface formed by beam sections 24a to 24i for mounting the uncoiler 82 (see Figure 6) and the cutting machine 83 (see Figure 6). The coil mounting section 16 includes, for example, a scaffolding board 61, handrails 62a, 62b, uncoiler mounting tables 63a, 63b, and cutting machine mounting tables 64a, 64b. The scaffolding board 61 is a platform on which workers can work. The scaffolding board 61 is a rectangular board that is approximately perpendicular to the ±Z direction and is positioned in the area between the beam sections 24d~24f and beam sections 24g~24i. The handrails 62a and 62b prevent workers from falling while working on the scaffolding board 61. Handrail 62a is provided at the -X end of the scaffolding board 61. Handrail 62b is provided at the +X end of the scaffolding board 61.

[0020] The uncoiler mounting bases 63a and 63b are elongated in the ±X direction, and the uncoiler 82 is placed on them. The uncoiler mounting bases 63a and 63b are positioned between the beam section 24b and the beam section 24c. That is, the uncoiler mounting bases 63a and 63b are located +Y side above the rail 81a and -Y side above the rail 81b. The cutting machine mounting bases 64a and 64b are elongated in the ±X direction, and the cutting machine 83 is placed on them. The cutting machine mounting bases 64a and 64b are positioned between the beam section 24a and the beam section 24b. That is, the cutting machine mounting bases 64a and 64b are located to the +Y side of directly above the rail 81a and to the -Y side of directly above the rail 81b. Because the uncoiler mounting bases 63a, 63b and the cutting machine mounting bases 64a, 64b are arranged in this manner, the overall length of the work platform 10 in the ±Y direction can be shortened compared to the case where the uncoiler mounting bases 63a, 63b and the cutting machine mounting bases 64a, 64b are arranged at the same height as the forming machine mounting bases 53a to 53d. Therefore, even if the distance between the rails 81a and 81b is short, the uncoiler 82, the cutting machine 83, and the corrugated sheet forming machine 84 can be stably mounted.

[0021] Referring to Figure 6, a construction method for constructing the roof of building 90 using the work platform 10 will be described. In this example, building 90 has a roofless section (rooftop floor surface 91) on the -Y side of the fourth floor, and roof support beams 92 are located on the +Y side of that section.

[0022] First, rails 81a and 81b extending in the ±X directions are installed on the rooftop floor surface 91. In this example, since the rooftop floor surface 91 is slightly sloped in the -Y direction, rails 81a and 81b are installed at different levels. Next, the work platform 10 is assembled on rails 81a and 81b. Corresponding to the level difference between rails 81a and 81b, the trolleys 13a to 13f have different heights from the trolleys 13g to 13l, which makes the beam sections 21g to 21l horizontal. Then, the sheet metal forming machine 84 is placed and fixed on the forming machine mounting bases 53a to 53d, the uncoiler 82 is placed and fixed on the uncoiler mounting bases 63a and 63b, and the cutting machine 83 is placed and fixed on the cutting machine mounting bases 64a and 64b. Furthermore, a generator mounting platform is placed between the beam sections 21i and 21l, and the generator 85 is placed on it. Wiring from the generator 85 is connected to the uncoiler 82, the cutting machine 83, and the corrugated sheet forming machine 84. As a result, the uncoiler 82, the cutting machine 83, and the corrugated sheet forming machine 84 are operated by the electricity generated by the generator 85. In addition, by positioning the generator 85 as close as possible to the +Y side end of the work platform 10, the center of gravity of the entire work platform 10 is shifted towards the +Y side, and the stability of the work platform 10 can be ensured even if a part of the work platform 10 protrudes beyond the rail 81a to the -Y side. With this, we are ready to install the corrugated metal roof using the rooftop molding method.

[0023] Next, a roll of steel sheets (coil) that will be used as roofing material is set in the uncoiler 82, and the uncoiler 82 pulls the steel sheets out of the coil. The steel sheets pulled out by the uncoiler 82 are cut to the desired length by the cutting machine 83 located next to the uncoiler 82. The steel sheets cut by the cutting machine 83 are folded into a corrugated shape by the corrugated sheet forming machine 84 located on the lower level. The steel sheets folded by the corrugated sheet forming machine 84 are discharged from the corrugated sheet forming machine 84 onto the roof support beams 92 and fixed to the roof support beams 92. The corrugated metal roof is constructed by repeating this process while moving the work platform 10 in the ±X direction.

[0024] As described above, the work platform 10 can be installed even in a location narrower than the length of the corrugated sheet metal forming machine 84. Therefore, it can be installed in the roofless portion of the rooftop floor to form the corrugated sheet metal roof on the roof. Consequently, the size of the work platform 10 can be reduced compared to the case where rails are installed on the ground 99. This reduces the cost of constructing the corrugated sheet metal roof. Furthermore, since the rails are not installed on the ground, exterior construction can be carried out in parallel with roof construction. This shortens the construction period and reduces costs.

[0025] As described above, for the scaffolding used for roof roll forming during corrugated metal roofing work, the 4th-floor driveway (truck berth) is utilized, and a cantilevered platform is erected from the floor of the driveway. Unlike when the platform is erected on the building's exterior wall from the level of the exterior floor, exterior construction can begin even if the roof work is not yet complete. Also, unlike when scaffolding is erected from the ground, the scaffolding is not large-scale, which helps to reduce costs. By setting up scaffolding on the driveway (truck berth) and extending it outwards, the size of the scaffolding can be reduced, thus shortening the construction period and costs. Furthermore, by carrying out exterior construction work at the same time, the construction period can be reduced even further. Even if scaffolding is extended outwards, the generator on the inside acts as a reaction force to maintain balance.

[0026] The embodiments described above are examples intended to facilitate understanding of the present invention. The present invention is not limited thereto and includes various modifications, changes, additions, or deletions without departing from the scope defined by the appended claims. This will be readily apparent to those skilled in the art from the above description. [Explanation of symbols]
