A construction temporary work is main process and importance trade section. A technology system of construction temporary has very low availability of field works and needs improvements in Korea as construction site has a quick response about new requirements. This study reviews literature researches and can verify that changes to a comprehensive technology system for construction site. In addition, it suggests a breakdown structure of new standards for temporary construction technology based on views of construction site managers. Meanwhile, temporary construction technology in Korea has changed with a specification of construction temporary work which had been revised in 2014. However, the revision is merely dividing the design and building off of construction temporary technology. It is lacking in many ways to change this in a new standard system for temporary construction technology. Henceforth, it needs to develop a standard system for temporary construction technology and a professional system that is appropriate for different purposes by detail trade sections.

In this study, in order to secure the necessity of introducing the safety certification system for the assembled temporary equipment and materials, the feasibility of the introduction was analyzed through literature review, structural analysis, and actual experiments and surveys related to the assembled temporary equipment and materials. In the previous studies, it was found that the research on the assembled temporary equipment and materials was insufficient, and it was possible to grasp the necessity of introducing the safety certification system for the assembled temporary equipment and materials. In addition, in the results of the serious accident analysis, it was found that the soundness of the temporary equipment and materials is determined by the structural characteristics after it was assembled. As a result of the feasibility analysis of the introduction of the safety certification of the assembled temporary equipment and materials through structural analysis, it is possible to effectively and rationally reflect the main geometrical influence factors, and to introduce the safety certification system that can test the procedures and procedures of the assembled temporary equipment and materials and based on it. It was found that there is a need. As a result of feasibility analysis on the necessity of introducing the safety certification system for assembled temporary equipment and materials through actual experiments, the existing single member performance evaluation has limitations in evaluating the structural performance of the assembled temporary equipment and materials. It was found that there is a need to introduce a safety certification system. As a result of gathering opinions on the feasibility of introducing the safety certification system for assembled temporary equipment and materials of manufacturers and users through the survey, it was found that the overall positive response result was high and the effectiveness was high.

건설 프로젝트의 초기단계에 타당성을 검토함에 있어서 공통가설공사의 경우 설계도서상에 표시가 되지 않거나, 시방서상에 간략하게 서술되어 있기 때문에 담당자의 경험 의존율이 다른 공종에 비해 높다. 이런 초기단계의 결전은 프로젝트의 진행과 더불어 많은 문제점들을 야기 시킬 가능성이 있다. 따라서 최근 활발히 논의가 되고 있는 기존 공사정보에 대한 실적 데이터베이스와 공통가설공사의 분류체계를 포함한 시스템을 개발하여 자료들을 분석, 활용함으로써 시공전(Pre-Construction) 단계의 공통가설공사에 대한 작업 및 원가 예측을 용이하게 하고, 후에 Feed Back 됨으로써 정확한 건설 프로젝트 타당성 분석을 가능케 하고자 한다.

Analyzed in the NFDS, The average number of fires in vinyl temporary buildings is more than 1,000 in annually. And the number of deaths and injuries was around 30 people in every year. According to the National Fire Agency, There are 142,386 vinyl temporary buildings for Agriculture and Fishery, of which 4,720 are residential vinyl temporary buildings in illegally. Model house is subject to regulation in fire-related law. But, even though it's the same temporary building, Vinyl temporary building is not subject to regulation. For this reason, Vinyl temporary buildings are left in the blind spot of fire safety. Therefore, In this study, We propose that amend of Act on installation and management of firefighting systems, make of temporary fire safety controller, develop and apply of alarm system that is connected to a single-alarm smoke dretector, organize and operate volunteer fire brigade of the crop group to prevent and extinguish the fire.

Temporary work that utilizes temporary equipment (e.g., system scaffold and system pipe support) in construction work is one of the most vulnerable work from a safety perspective in South Korea. Typically, temporary equipment is reused at construction sites. The Korea Occupational Safety and Health Agency announced guidelines regarding the performance standards for reusable temporary equipment to prevent the accidental collapse of temporary facilities. Nevertheless, temporary facilities' collapse still occurs, which could be attributed to a degradation in the performance due to the reuse of temporary equipment. Therefore, this study investigated the performance of simple temporary structures assembled with new and reused equipment. To this end, an experimental module was designed based on previous research cases, and two experimental models were constructed, in which one was assembled using new equipment (Model A), and the other was built using reused equipment (Model B). To determine the performance of each model, a load test was conducted to measure the maximum load that each model could withstand. The experimental results revealed that the maximum load of Model B was 15% lower than that of Model A. This indicates that there is a meaningful performance difference between those two models. Based on this result, the authors decided to perform additional tests with more realistic models than previous ones. The new experimental module was designed to ensure compliance with the Korean design guidelines. In this presentation, the authors show details of the first tests and their results and plan for the additional test.

건설가설공사는 타워크레인, 리프트와 같은 가설양중설비나 사무소, 창고, 시험소 등의 가설건축물 및 각종 작업에서 사용되는 비계, 작업발판, 동바리, 거푸집 등을 일시적으로 조립, 설치하여 사용하고 공사가 완료된 후에는 철거하는 건설공사의 주요 과정인 동시에 핵심공종이다. 새로운 요구사항에 대한 건설현장의 발 빠른 대응과는 달리 국내의 건설가설분야의 기술체계는 실무에서 효용성이 낮아 개선이 필요한 실정이다. 이에 본 연구에서는 기존 기술체계와 현업에서 활용되고 있는 새로운 기술과 기법 등을 정리하고, 현장관리자의 의견과 검토를 통한 가설기술의 기초가 되는 기술요소의 분류체계를 구축하였다. 이를 바탕으로 향후 건설가설기술요소에 대한 성능과 활용성에 대한 연구를 통하여 지식정보체계로 거듭날 수 있도록 개선해 나갈 예정이다.

Generally main girders and steel piers of temporary bridges form the steel rahmen structure. In this study, the rational stability design procedure for main members of temporary bridges is presented using 3D system buckling analysis and second-order elastic analysis. 2 types of temporary bridges, which are possible to be designed and fabricated in reality, are chosen and the buckling design for them is performed considering load combinations of dead and live loads, thermal load, and wind load. Effective buckling length of steel piers, effects of live loads on effective length of main members, transition of ~id buckling modes, and effects of second-order analysis are investigated through case study of 2 temporary bridges.

건설 가설재 성능검정제도의 전환기에 들어서 주요 가설재들의 성능검정을 평가하고 선진국의 관련 체계와 비교하여, 안전인증제를 통해 새로운 건설공사용 가설재들의 인증제도를 제안하고자 한다. 현재의 성능검정제도는 1992년에 시작되어 2003년에 재 개정되면서, 3년마다 재 검정을 받도록 하고 있다. 그러나 제조능력을 향상시키지 못하고 업체 간 가격경쟁의 심화로 인해 대부분 같은 형태, 기능의 제품만을 양산하고 있는 실정이다. 기존 성능검정제도에서 안전인증제로의 전환은 보다 체계적인 심사방법 및 품질관리 시스템을 포함하고 있으며, 건설 환경 변화에 대응할 수 있는 다양한 요구사항에 맞춘 규격을 제시할 수 있도록 하고 있다. 안전인증제를 통한 건설공사의 가설재는 의무인증대상과 임의인증대상으로 나누어지며, 종전보다 제품의 품질과 관리 시스템을 향상시켜줄 수 있을 것으로 기대된다.

강교량 가설공사의 설계는 그동안 과거유사사업의 자료를 토대로 설계자의 경험에 의존하여 진행되어 왔다. 이로 인해 실제 현장에서 소요되는 가벤트에 대하여 과대설계 논란이 있으며, 시공단계에 불필요한 설계변경을 야기하고 있다. 본 연구에서는 강교의 설계작업 과정에서 생성되는 설계 자료와 가설공사의 수행에 필요한 자원에 대한 데이터베이스를 구축하여 강교 설치 가설공사의 최적화설계 지원 시스템을 개발하였다. 이를 통하여 가설시설물에 대한 설계를 최적화하며, 설계변경을 줄이는 데에 기여할 뿐만 아니라 설계정보를 시공단계에 활용하게 함으로써 업무의 효율성과 정확성을 제고하였다.
