Generally, a safety workstation for inspection and maintenance inside a large boiler furnace (collectively referred to as a safety workstation required for performing a work such as a scaffold safety footplate) frequently incurred safety accidents due to a high-temperature operation during installation and demolition work .

Accordingly, in order to solve the above problems, Korean Utility Model Publication No. 20-0408501 discloses a frame having a plurality of horizontal bars installed between a pair of vertical bars, a side connecting member connecting the pair of frames so as to overlap each other, And a length connecting member for connecting and fixing the contact portions of the frames so that a plurality of the connecting members can be used in the longitudinal direction.

However, the above technology can easily access the inside of the boiler furnace, but it does not satisfy the environmental condition that various workers can work at the same time. In addition, since the height of the boiler is several tens of meters, There is a problem that the work stability and scaffold durability are lowered because a plurality of frames are connected in the longitudinal direction by using a member.

Therefore, in order to solve the above problems, it is an object of the present invention to provide a pendant assembly method capable of improving the stability of a scaffold for supporting a scaffold for approaching an operator during a work in a boiler room, A scaffolding system was developed.

In the prior art of the pendant assembly type scaffold system described above, Korean Patent No. 10-1236184 discloses a structure in which the load of the scaffold is dispersed upward and downward to prevent the load from being concentrated only to the lower portion, A method of installing and dismounting an inside wire scaffold in which a plurality of operators can perform inspection or maintenance work simultaneously.

However, the above-described technique still adversely affects the soundness of the tube when a full load of the pendent scaffold is transferred to the plate-type superheater tube bundle and a long-time temporary work station is installed. When applied to a vertical type superheater tube bundle boiler, There is a problem that it is not suitable and is difficult to apply due to structural interference due to the nose portion.
