건설 현장이나 일반 제조업 현장은 작업자의 고소 위치에서의 작업시, 필요한 특정 장소로의 접근을 위한 임시 구조물을 설치하는데 이를 가설비계라고 한다. 이러한 가설비계는 작업자의 안전 통행과 작업을 위한 받침대 역할, 장비나 공구, 자재를 임시 적치하기 위한 장소로 활용되는데 일반 건축물과 중후장대한 조선소 블록 제작등에 필수적으로 사용된다. 하지만 가설설비라는 특성으로 비계와 관련된 연구가 부진하고 사업적으로 참여하는 사업주 또한 진출을 가볍게 생각하고 있으며 해당 공사에 임하는 작업자의 산업으로의 진입문턱도 낮은 등으로 시공 품질이 떨어질 우려가 매우 높다. 또한 설치후에는 품질검사가 어려워 작업자의 숙련도나 진정성 등에 의한 주관적 작업 결과물이 설치된 시설물을 사용하는 주변 작업자에게는 불안전 요인이 되기도 한다. 이에 작업자의 숙련도나 주관적 판단에 의한 가설 구조물 설치를 회피하여 안전성을 높이기 위한 방안이 연구되어 왔는데 이것이 시스템비계이다. 이러한 시스템비계에 대한 사용성을 확대하기 위해 국토교통부와 고용노동부등의 정부기관에서는 여러 가지 제약과 동시에 장려정책을 제시하고 있으나 공적 발주나 일부 대기업그룹 외의 중소 현장에는 그 확산 속도가 높지않은 편이다.

The government [3] specifies steel pipe scaffolding as conventional scaffolding and is promoting the installation of system scaffolding, an integrated work platform, and avoidance of the use of steel pipe scaffolding as much as possible. However, in places where equipment cannot enter, such as power plants and plant sites, places the structure is complex, and places where scaffolding cannot be stacked on the ground, there is no choice but to install steel pipe scaffolding. When installing steel pipe scaffolding on an H-beam structure at a high place, the performance of the steel frame clamp is very important in order to form a work space which workers can work safely. In this study, the displacement magnitude and tensile load of members in each installation direction of the clamp for steel frame were verified through performance tests and structural analysis modeling. As a result, it was confirmed that the performance for each installation direction satisfies the safety certification standard tensile load of 10,000N. Although the performance value is satisfactory, deformation of the attachment pressing bolt was verified and was confirmed to have minimal deformation. Thus, to ensure the load is properly to the attachment body, the clamp for a steel frame must be installed in the direction in which the load is transmitted.

해양구조물에서 발생하는 부상의 원인은 고소작업 중 추락, 물건의 이송 중 미끄러지거나 걸려 넘어짐에 의한 부상 등이 대부분을 차지한다. 이에 따라 부상을 유발하는 주요 위험작업에 대한 안전선진국의 규정 및 교육기관의 교육 내용을 우리나라의 것과 비교하여 우리나라의 현황과 개선방향을 검토하였다.

Thanks to various efforts to reduce disasters by the government and the Health and Safety Authority, disasters across industries and the construction industry show their reduction trend. However, the falling disasters in the construction industry have not decreased and increased on the contrary. Especially falling disaster caused by Hanging Scaffolding is the most critical disaster which shows low occurrence frequency but is directly connected to death of worker. The working environment for Hanging Scaffolding is poor in domestic construction site. In particular, the Hanging Scaffolding workers in small construction sites are not on the safety control and management by anyone for their works. They are driven to unsafe working condition with mostly uncertified facilities which are made by themselves. Therefore, this study is focused on searching falling disaster factors from the 242 disaster cases caused by Hanging Scaffolding Work in 15 years presented by KOSHA, and trying to provide suggestions for improvement. The improvement of the method of work requires facility improvement and work due to high accident rate caused by unsafe behavior. Analysis of the case of a disaster occurring over the past 15 years shows that no disaster occurred due to problems in the order of operations presented by KOSHA. However, it was found that many accidents resulted from death caused by safety belts not being installed or attached to ropes using safety belts without following the order of work. The most important aspect of improving the work method was the installation and wearing of lifeboats and safety belts.

Designers and builders are omitting structural design and relying on workers' experience, due to the lack of awareness of the importance of scaffolding in domestic construction sites, and there is a high probability of collapsing accidents such as inappropriate wall joint installation and non-compliance with work procedures. Therefore, risk factors were analyzed in detail and major risk factors were derived from opinions of site managers and scaffolding experts in this study.

Boilers of large-sized coal-fired power plants are being operated under very poor conditions such as continuous operation or repeating of start-up and shutdown for a stable supply of electricity. Thus periodic inspection and maintenance are required to ensure reliability of operation. The loads of existing scaffolding systems for the maintenance of boilers are concentrated in the lower parts structurally, which may cause a serial collapse of the overall scaffolding system when there are problems in some members. Therefore, in this study, a safe furnace scaffolding system is developed by dispersing the loads in the upper part, as well as minimizing the hazards of serial collapsing. In addition, for cases where the direct installation of furnace scaffolding is challenging owing to the structure of the boiler tube, a lifting system for the installation of furnace scaffolding is developed so that furnace scaffolding can be supported to secure the integrity of the power generating facility.

해양구조물에서 근무하기 위행서는 기초안전교육을 받아야 한다 그러나. 각 국마다 다른 기초안전교육의 표준을 갖추고 있어 현황을 조사하였으나 대부분 영국을 중심으로 한 OPITO를 표준으로 하여 근무인력에 교육을 하고 있다. OPITO 교육은 법적 강제성이 없으나 세계적 표준으로 통용되는 현황에 대하여 조사하고 우리나라의 Offshore 산업 현황을 검토 하고 OPITO의 사례를 롤모델로한 우리나라의 발전방향을 검토 하였다.

In this study, the UAV (Unmammed Aerial Vehicle) was applied for the photogrammetry of the construction site and the safety management of steel pipe scaffold. The research site is a temporary facility for building reinforcement on Samcheok Campus of Kangwon National University. The installation condition of the steel pipe scaffold was investigated, and the pillar distance, the beam distance and the wale distance were surveyed. As a result, it was found that the beam distance of the scaffold in the longitudinal direction was in good agreement with the standard, but the pillar distance and the wale distance were found to be less than the standard. Three-dimensional data can be used in drone shooting to enable three-dimensional measurement, so that it is possible to measure facilities hidden or located inside other facilities. Through the drone shooting, the condition of the site can be quickly recorded and the surveying can be carried out without interfering with the work of the field personnel. Although the installation of the temporary structure must be strictly observed to ensure the safety of the workers, it is found that the installation standards are still neglected in the field. In order to prevent this practice, it was thought that the legal system should be supplemented so that it could be checked periodically by using UAV in the field process management.
