Background
As a conventional invention, there is an authorized patent registration No. 10-1412860 (title of the invention: operation method of corner adjusting device of scaffold system), which is known from registered patent publication.
As shown in fig. 1 and 2, the above-described conventional invention relates to a corner support portion 6 of a scaffold device 3 provided to secure a working space in a cargo space 1 of a liquefied natural gas ship, and the corner support portion 6 is provided at a corner portion between side support portions 4 and 5 facing a cargo tank wall surface 2 at both sides in a right angle direction when viewed in a planar direction in the drawing.
The side support portions 4 and 5 and the corner support portion 6 are respectively configured by providing a connection portion provided in a known column for temporary mounting material (for example, a column of utility model No. 20-0384333) with a terminal connection portion of a horizontal frame in a cantilever manner and then providing a step plate on an upper portion of the horizontal frame.
Further, by providing the side surface sliding support portions 7 and the corner sliding support portions 7a in the sliding type telescopic manner at the both side surface support portions 4 and 5 and the corner support portion 6, the tip end portions of the respective sliding support portions 7 and 7a are brought close to the cargo compartment wall surface 2, and thus, a required operation can be performed safely.
As shown in fig. 2, the angular support portion 6 of the conventional invention is provided with a pillar coupling portion 8 detachably inserted and coupled to the coupling portion of the aforementioned pillar at the upper right corner portion of the quadrangular sash frame 9 disposed along the horizontal direction, and each pair of first and second slide bars 10 and 11 is slidably extended and contracted at the left and lower sides of the quadrangular sash frame 9 in the drawing, and foot plates are provided on the first and second slide bars 10 and 11, which will be collectively referred to as angular slide support portions 7 a.
The angular support portions 6 according to the conventional invention as described above are individually disposed horizontally, not connected to the both side surface support portions 4 and 5 disposed in the right angle direction, and only the pillar coupling portions 8 provided at the corner portions of the angular support portions 6 configured in a quadrangular plate shape as a whole are coupled to the pillars, and according to this state, if a weight is placed on the angular support portions 6, the free end portions of the angular support portions 6 disposed in a cantilever manner are bent downward.
The reason why the angular support portion 6 has a quadrangular plate shape is described above is that the angular support portion 6 has a quadrangular plate shape because the angular support portion 6 is formed into a quadrangular window frame shape by a quadrangular pipe and a pedal is provided on the upper side thereof as shown in fig. 2, and therefore, the angular support portion 6 has a quadrangular plate shape for convenience.
As described above, only one side corner portion of the corner support 6 configured in a quadrangular plate shape is coupled to the column, and thus, even if it is not a heavy object, the operator may hang down due to the continuous movement of the operator, the weight of materials, equipment, and the like, and the height of the corner support may be lower than that of the side support 4 and 5 adjacent thereto, which may cause a short step and cause the operator to trip during movement.
Further, 3 slide bars 10a, 11b of the first and second slide bars 10, 11 on which the step is placed have the same height, and 1 slide bar 10b provided at the corner portion of the free end portion side on the opposite side of the pillar coupling portion 8 has a height lower than the upper 3 slide bars 10a, 11b, so that there is a problem in that the step cannot be provided at the same height on the first and second slide bars 10, 11 on both sides, and therefore, there is a problem in that the step should be provided after another support member having a height equal to the height of the remaining 3 slide bars is provided on the 1 slide bar 10b having a lower height.
