2. Description of the Related Art A folded plate roof is formed by stacking adjacent peripheral portions of a folded plate forming the roof and fastening the overlapped portions with fastening bolts. It is arranged every 1 to several rows, and every 500 mm to 700 mm in the flow direction.
It projects upward at a height of about 0 mm. If the unfolded roof is left as it is, the rust will become severe and it will decay, so it is preferable to repaint it regularly, but as a pretreatment for painting, it is necessary to carry out a blasting work to remove rust on the surface and old painting to some extent. . For example, when trying to perform this blasting work using a blasting device with a shoulder-mounted rotating brush, I was forced to walk on the origami plate and its feet were wavy,
As mentioned above, many fastening bolts are scattered on the top of the wave peak where it is easy to put a foot on, so there is a risk of falling and injury. The work was extremely poor and demanding because it was exposed to cold wind. From the above circumstances, the pretreatment work for painting on the origami roof tends to be regarded as difficult, and therefore, the applicant of the present invention has previously proposed the oriental roof cleaning device as shown in Japanese Utility Model Publication No. 4-18130. Proposed. As shown in FIG. 7, the folding roof cleaning device 90 includes a traveling carriage 95 provided with a guide wheel 93 and a traveling wheel 94 which travel in the folding wave groove 92 of the folding roof 91, and the folding wave groove 92. A rotating brush 96 having a shape of an inverted circular truncated cone that is substantially fitted to the inside of the plate is attached to the guide wheel 93 and the traveling wheel 94 while traveling in the folding wave groove 92. And so on. The weight of the folded roof cleaning device 90 was about 60 kg, which is similar to the weight of a human, and was easy to use, and the construction efficiency was about 10 times the human power.

In the work, the operator installs the folding roof cleaning device 90 at the lower ends of the rotating brush 96, the guide wheel 93, and the traveling wheel 94. The troublesome work of lifting up to the position above the height of the upper end of the fastening bolt 98 of the origami plate protruding from the bottom of the wave peak 97 to the top of the wave peak and moving to the upper position of the adjacent wave groove It was a lot of work. Since the origami roof 91 is adopted in a large-scale building and the origami wave grooves 92 are provided at a pitch of around 250 mm, the number of rows of the wave grooves is very large and the work for carrying out the moving work is performed. For a person, about 60k near the end of each wave groove
In order to lift the folded roof cleaning device 90, which is a heavy object of about g, to a height not less than the depth of the wave grooves, it is a heavy work and
While lifting, there was a problem that there was a high risk of being injured by falling due to the unevenness of the roof underneath. The present invention has been made in view of such circumstances, as described above, a folded plate roof cleaning device having an excellent cleaning function can be safely installed in the adjacent wave groove.
