2. Description of the Related Art In a high-rise steel building, the work of attaching a folded sheet made of thin steel sheet to a roof is conventionally performed by a material maker who visits a site each time, supplies a material, hits a roof dimension, and takes it back to a factory. After the forming process at the factory, the roofing material is cut into required dimensions according to the roof length, and the roofing material is collectively brought into the site, carried one by one to the construction site by many people, and pasted. Was.

[0003]

According to the conventional roofing method, the roof material is formed into a folded plate or the like at a factory, cut into a required length according to the site, and then transported to the construction site. Therefore, it takes a lot of time and effort to carry in the material, and in the case of a thin iron plate, it is extremely inconvenient to carry and carry it because it deforms in a complicated manner, and the folded plate is, for example, 500 mm thick. It is a thin iron plate of 1 mm or less and has a length of about 12 m. It takes several people to carry it to the construction site, and there is a problem that it takes a long time to carry out the construction even if it is lifted with danger.

[0004]

The first aspect of the present invention is a folded plate in which a factory-shipped hot coil, which is a raw material of a roofing material, is directly carried into a construction site and is incorporated in a movable work floor moving along a building to be constructed. A method of forming a thin flat iron sheet drawn from a hot coil by a forming machine into a roof sheet material just before construction, and sending it to the roof frame surface as it is, transporting it, cutting it each time according to the roof length, and attaching it to the construction It is characterized by.

[0005] As an apparatus for carrying out the above-mentioned construction method, a folding plate forming machine and a shearing machine on a sending side thereof are installed on a top floor of a movable work floor which moves by itself on a rail laid along a construction building, The thin steel sheet drawn from the hot coil of the thin steel sheet placed on the bed of the moving work floor is folded and processed by the folding sheet forming machine, cut out to the required dimensions, and the sheet metal is cut adjacent to the folding sheet forming machine. juxtaposed power operation panel projecting from the hoist arm Te, the hoist arm is suspended a lifting off poke each hoist to secure several hoists to, respectively hoist two motors on the hook A self-propelled machine that supports a driven wheel and two driven wheels is hung in a freely detachable manner, and each self-propelled machine is protruded with a horizontal rod with a magnetic suction cup made to be attractable by a permanent magnet at the tip. It is characterized by the configuration provided.

[0006]

According to the present invention, a hot coil of a thin steel sheet before forming processing to be a roofing material is carried into a site, and cut and adjusted to a site size while being formed and processed by a folding plate forming machine incorporated in a moving work floor, and a roof is applied. The movable work floor shall be constructed so that the top floor is assembled at the same height as the roof frame construction surface, and it will move on rails according to the work progress of the roof stuck construction site, A hot coil in which a thin iron plate of a required thickness before forming is wound on the floor is pivotally supported, and the thin iron plate drawn out from the hot coil is fed to a folding plate forming machine installed on the top floor to be folded into a required size.

The processed folded plate is sent out to the roof construction surface as it is, but in the construction, the first two rows are manually pasted, and then the hoist protruding from the power supply operation panel on the work floor Hook on arm hoist
After lifting several suspended self-propelled machines with a hoist, placing the drive wheel with motor and the driven wheel on the folded plates stuck in two rows, and then folding the plate to be processed and sent out Operate the switch on the power supply operation panel to sequentially move the sheet roofing material.After holding the magnetic suction cups of the horizontal rod of the self-propelled machine in sequence, hold each self-propelled machine at the same time to construct the folded sheet roofing material. Carry it to the site , and at the same time cut it with a shearing machine at a position corresponding to the length of the construction site and paste it as it is.

[0008] Therefore, it is easy to bend and deform, so it takes only one person to carry it to the construction site, which requires several workers, and it is very quick to carry in the material, carry it in and carry it to the construction site, and the work efficiency is good. The rail arm is a substitute for a lifeline. The hot coil on the bed serves as a balance weight for the moving work floor, and the balance is further improved if spare hot coils are juxtaposed.

[0009]

[Example] In the present invention, a roof material molded and measured in a factory is carried into a site in accordance with the size of the site once, and the folded plate is transported to a work place by several workers, and affixed. Conventional roof stitching work, molding and measuring and cutting are performed on site, and transport to the construction site is also performed automatically
As an embodiment of the apparatus, assembling according to the height of the construction roof, a folding plate forming machine 4 and a folding plate forming machine 4 are mounted on a top floor 3 of a moving work floor 2 which moves by itself on rails 1 along the building. A shearing machine 5 is installed in contact with the delivery side, and a hot coil 7 factory-shipped with a thin iron plate of a required thickness is pivotally supported on a bed 6 of the moving work floor 2 and the thin iron plate 8 drawn from the hot coil Is cut by a shearing machine 5 in a size corresponding to the site as it is, and a folded plate is formed on the top floor 3 of the moving work floor. A power control panel 11 having a hoist arm 10 projecting from and adjacent to the molding machine 4 is juxtaposed, and several hoists 1 are mounted on the hoist arm.
2 and the hoisting hooks 13 are hung respectively, and each of the hoists 12 has two driving wheels 14, 1 with a motor.
A self-propelled machine 16 supporting four and two driven wheels 15, 15 is suspended, and each self-propelled machine can be attached and detached with a permanent magnet at the tip.
The magnetic force sucker 17 is made to hang down and a horizontal bar 18 is made to protrude. 7 more stable causes the balance by increasing the weight load of the mobile work bed hot coil.

At the time of construction, the moving work floor 2 is moved along the construction building to the place where the roof is stuck, and the thin steel sheet 8 drawn from the hot coil 7 supported on the bed floor 6 is folded.
To form a single folded plate, and to send it out, first carry it to the roof construction surface with several workers as before, cut it with the shearing machine 5 at the required length, and paste it. Execute. In this way, the two folded plates A are manually pasted in two rows to provide a scaffold for subsequent automatic conveyance.

Next, the mobile work floor 2 is laterally moved to be lifted on the hoist 12 of the hoist arm 10, and the motor driven wheels 14 and the driven wheels 1 of several self-propelled machines 16 suspended by the hooks 13.
5 are laid one by one on two rows of folded plate roofing materials A and put on standby. And three rows that are molded and sent out from the third sheet
The folding plate roofing material A eye is sucked and held by the magnetic force suckers 17 hanging down to the tip of the horizontal bridging rod 18 of the self-propelled machine 16 has been removed from the hook, and by driving the motor with driving wheels 14 to run a self-propelled machine The folded sheet roofing material A is transported to the attaching position. Then, the base is cut by the shearing machine 5 at the time of being located at the pasting site, and a folded plate is pasted at that position . In this case, only one worker needs to watch the folded plate sent and conveyed and perform the sticking operation. The hoist arm also serves as the worker's lifeline.
Power is supplied to the self-propelled machine by a reel wire 9 from a power supply operation panel 11.

When the sticking operation is completed, the movable work floor is moved laterally, and the traveling wheels of each self-propelled machine suspended by the hoist 12 are transferred onto the newly-attached folded plate. The work of adhering, holding and transporting is then sequentially repeated. When a spare hot coil is placed on the bed of the moving work floor, a weight load is applied, and the stability of the work floor is further improved.

[0013] The folded sheet, which is a thin steel roofing material, is bent and deformed by hand when it is transported to the sticking position, so that it is difficult for several people to handle it. In the method of the present invention, the self-propelled machine carries the material adsorbed by the self-propelled machine, transfers the self-propelled machine to each folded plate that has been pasted, and automatically cuts it to the required dimensions every time the folded plate formed at the site is sent out. Work can be done very quickly, efficiently and safely. For the cutting operation of the shearing machine, a sensor can be wired at the leading end position of the folded plate feed to detect the position and automatically cut.

[0014]

According to the present invention, in roofing construction of a steel-framed building, the loading and sizing of a folded thin steel sheet to a place where the work is to be performed is automated, and
In addition, since it is a construction method that uses a moving work floor to process the forming and feeding from a hot coil to a folded plate just before pasting it on site, it is extremely easy to handle roofing materials, it requires less labor, labor saving, safe and construction time The work efficiency is significantly improved and the construction period can be shortened.
