Description

Remote Erecting Suspended Scaffolding and the methods}

The present invention relates to scaffolding and scaffolding to maintain the ceiling of a structure, such as when working under a ceiling such as an absorption tower in a boiler or desulfurization plant. More specifically, the present invention relates to the field of assembling the scaffolding under the ceiling using only hand tools because the assembling aid is difficult to enter into the structure.

Background art of the present invention is a method and apparatus for inspecting the top of a large structural member such as a bridge, boiler, pressure vessel. Normally, in order to go up to work in high places, ascending scaffolding from the ground one by one in succession. US Patent 4496026 (Jan. 29, 1985) “Founding ladder system” discloses a technique for stacking up a scaffold from the bottom of the boiler to the top of the boiler. However, this method of laminating from the bottom up is the top part of the work where the work is to be done, which requires the construction of a scaffold in the middle from the top to the bottom.

In order to improve this, a method of hanging a scaffold under the ceiling of a structure has been adopted. Hanging scaffolding under the ceiling of the structure is used in the Republic of Korea Patent Registration 20-0392341 (August 02, 2005) "fixing device for aerial scaffolding" to check the top of the bridge floor or to assemble the scaffold for the construction An aerial scaffold using a wire rope, one end of which is connected to a fixed portion of a second side, and the other end of which is detachably connected to a steel pipe that is a horizontal member of an aerial scaffold. Alternatively, U.S. Patent 6817444B1 (Nov. 16, 2004) “Suspended work platform” is a method and apparatus for constructing scaffolds for temporary work by hanging wires on the ceiling of structures such as bridges and connecting the lower part with steel pipes that are horizontal members. Is disclosed.

Also similar to the present invention is disclosed in US Pat. No. 4,413,707 (Nov. 8, 1983) “Suspended chain scaffolding employing adjustable posts with chain threaded therethrough” for scaffolding for work on the ceiling.

The present invention is to install the scaffolding work when it is necessary to work under the ceiling at a height out of reach of people from the power plant boiler or bridge, tank, absorption tower or the floor of a large building, this work is to install the scaffolding In the event that a construction aid or an auxiliary equipment, such as a crane, is required to work only by personnel, hand tools, or portable equipment due to failure to reach the construction site of this work platform, We will develop a method and device that can be easily installed in the air while protecting the assembling / disassembly of scaffolds by working only in a safe scaffold or on the floor of the structure. . The present invention therefore relates to a scaffolding system and method for ensuring the safety of an assembly worker installing a scaffold in the air just below the ceiling.

The present invention is to install / dismantle the scaffolding work under the ceiling of a large structure, out of reach of people, the scaffold member required for this work must be assembled / disassembled only by manpower, hand tools, portable equipment in the air It is intended to develop a method and apparatus that can easily install scaffolding in the air while protecting workers who install / disassemble working scaffolding. To this end, the operator always wants to develop a method and apparatus for installing the scaffold at the lower part of the unit where the scaffold is installed by simultaneously lowering the material to be assembled on the ceiling plate or on the already assembled scaffold scaffold. do. For this purpose, the remote control member and the foot control member can be detached / attached to the member to be assembled under the ceiling by a simple method, so that the operator can hold the remote control member and the foot control member by hand, and the vertical rod, which is a component of the scaffold below, I want to assemble the rungs, railings, scaffolding, and braces. In order to ensure that the scaffold that is assembled under the ceiling below the normal 2m height can be safely and easily assembled / disassembled, the vertical member connecting means and the horizontal member connecting means are guided by the automatic guide means and are automatically assembled. Raised.

As described above, the operator who assembles / disassembles the scaffolding in the air assembles / disassembles the scaffold that is installed / disassembled adjacent to the already assembled scaffold or structure, and the safety is dramatically improved. With the advent, there was no need to build scaffolding from floor to ceiling, which drastically reduced the cost of work such as maintenance and improvement of large structures and the occurrence of industrial safety accidents.
