| 摘要(中) |
營建人員往往由於工作需要，需長時間維持在不自然的姿勢下工作，而施工姿勢不良會導致部分姿勢之壓力增加、疲乏等不良結果。本研究基於模板工程為建築興建常見之工種，而模板工長時間因重複動作多、工作環境劣、休息時間短等因素影響工作效率與安全，所以有必要針對模板工姿勢進行評估並提出相關改善與建議。因此，本研究目的在於探討模板工從事各類項目暴露危險等級的時間頻率。 本研究依據現場拍攝影片，利用影像定格及其重複性姿勢觀察，繼而使用OWAS、REBA、PATH三種姿勢評估工具探討模板作業姿勢傷害，並比較四者之間評估結果的適用性。其驗證顯示，若短時間須評估模板勞工姿勢，可利用較快速、省時之REBA評估姿勢工具。另外，本研究藉由REBA姿勢分析，研判各類作業項目姿勢之傷害評估，若將分析之傷害程度，依危險等級由高至低排列，則得出版模板(88%)、樑模板(76.67%)之危害姿勢暴露程度最高。經觀察推估一天施作八小時之暴露時間，依次為版施作(7.2 hr)、樑(6.38 hr)，藉此可當作勞工施工流程之參考，以免勞工長期暴露於危險工作姿勢，產生肌肉酸痛。為此，模板工在施作樑、版作業時應改善模板之施工姿勢或增加勞工人數，冀望可降低工作姿勢風險的傷害，以增加整體施工的安全與保障。 |

| 摘要(英) | It
is often necessary for the construction workers to work by
keeping unnatural postures. Their unhealthy working postures
will cause their some postures have such bad results as higher
pressure and fatigued. Because the formwork is a common type of
building constructions and the formworker’s work efficiency and
safety are often influenced by such factors as repetitive
motion, bad work environment and short rest time, this research
needs to assess the posture of formworkers and then provides
related improvements and suggestions. Therefore, the purpose of
this research is to study the time and frequency for the
formwork being at various risk exposure levels. With the films shot on site, this research takes use of freeze-frame pictures and observations on repetitive postures and further adopts such four posture assessment tools as Ovako Working Posture Analyzing System (OWAS), Repaid Entire Body Assessment (REBA), Posture, Activity, Tools and Handling (PATH) to study the postural injury in the formwork operation. This research also compares the above four tools to assess the applicability. The test shows that we can use REBA tool, which is more rapid and time-saving, to assess the formworker’s postures in short time. In addition, this research uses REBA analysis to decide the assessment of postural injuries in various operations. If the analyzed level of injuries is ranked according to their risk levels, we can find that the risk exposure levels for unhealthy postures in formworks and beam moldboard works are 88% and 76.67% respectively, which are the highest. Through the observation, we estimate the exposure time for eight-hour work hours a day is 7.2 hours for the moldboard and 6.38 hours for the beam work, which can be provided to the workers as a reference for their construction procedure, to prevent the workers from long-term exposures to hazardous working postures and having muscular pains. Therefore, during the construction of formworks and beam moldboards, we shall improve the working posture of formworkers or increase the number of workers in hopes of reducing the postural injury risk and increasing the whole construction safety and protection. |
