And a cheolgolbo assembling mechanism using a guiding wire-shaped connector to allow the cheolgolbo to be assembled more safely, simply and accurately by the weight of the complex cheolgolbo and the cheolgolbo assembling method using the same.

In general, cheolgolbo assembly work is one of the construction work that a lot of safety accidents occur frequently in the construction work. Looking at the conventional building construction method, there is always a risk of safety accidents because the field worker is relying only on the fall prevention harness or lifeline to assemble the cheolgolbo in the upper floor to the pillar. In addition, there is a limitation that construction of the building structure that can maintain the building quality within the displacement allowed by the building only if the assembly of both ends of the cheolgolbo at the same time. Therefore, the assembling work of the cheolgolbo is undergoing a dangerous process of fastening the bolts after the site worker to get on the cheolgolbo and pull or push the steel frame members that are moved down from the lifting device such as tower cranes. However, due to the sudden rotation of the cheolgolbo (rotation) during this work, accidents frequently occur, and also safety accidents such as falling, pinching, winding, stenosis of the field workers during the assembly work. In addition, there is a shortage of functional personnel capable of assembling steel members professionally, resulting in increased construction costs and delayed construction periods, which in turn causes a significant reduction in the competitiveness of the construction industry.

In fact, in September 2004, the site worker suddenly lost the center of the body and fell below 15m while the site worker suddenly lost the center of the body while standing on both sides of the steel girder member joints to perform the prefabrication of the four-floor steel gimbal at the new construction site in Yongsan-gu, Seoul. In January 2008, in order to assemble the two-story steel frame pillar in Pyeongtaek-si, Gyeonggi-do, the workers lost their center and fell to the ground floor below ground about 9m. There is a serious problem that safety accidents are continuously occurring in relation to the steel cheolbo assembly work, such as a dead disaster, and the field workers who perform the steel cheolbo assembly work are always exposed to the risk of safety accidents. Therefore, it can not be overemphasized to secure the fundamental measures to be safer, faster and simpler to perform the steel cheolgolbo assembly work.

However, in the construction sites to date, without a fundamental countermeasure against safety accidents occurring during the assembly of the steel frame beams, when the steel frame assembly work is simply performed, a temporary passage is fixed to the main moving passage, and a safety belt attachment facility (life rope) After installation, there is a problem that only the old-fashioned safety countermeasures for workers to wear the safety belts and work on the attachment facilities are presented.

In order to solve some of the problems of the steel cheolgolbo assembly work, Korean Patent Application No. 10-2004-75941 filed on September 22, 2004 discloses a steel structure assembly set using H-beams.
