곤돌라 지지대 고정에 따른 수직 및 경사 파라펫의 구조적 성능

다국어 초록 (Multilingual Abstract)

The exterior wall maintenance of a high-rise building is regarded as important, both in terms of the building maintenance itself as well as to ensure a good image for the building. As there are risks and economic disadvantages involved in using manual workers for this work, Robot Systems have recently been introduced as an alternative means. The existing Gondola Supporting means use heavy weights or anchors for the supporting points. However, these impose a weight load and cause damage, leading to problems for the roof or the building. Therefore, the study is trying to achieve a safe range of Supporting point loads for the Gondola-type Robot System by using a non-structural Parapet. This study carried out the structural analysis of parapet shape and thickness, which had been determined in the preceding studies, through the programs and the Korean Building Code-Structural. In addition, structural experimental specimens were made with the same concrete pouring method as used in the practical sites to conduct the structural experiments. Based on the comparative analysis of the experimental results and analysis results, were understood the range to be used as a structural element. Through the experiment, it was shown that 45° and 60° sloped Parapets, compared to a 90° vertical Parapet, have a failure load lower than theoretically expected due to the changes in the axial force and moment as well as defects on the construction joints. As construction joints are considered to be relatively fragile structures, they are subject to further safety inspection when being used as structural Parapets. All 90° vertical and 45°, 60° sloped Parapets with thickness 150mm, double reinforcement are analyzed, and it has been proven that they are able to withstand 10kN Gondola-type Robot System weight load.
