项目摘要

In this research, the experiment and the examination were conducted aiming to evaluate the workers physical stability when they work and walk in construction sites, and the analysis of the industrial accidents and the investigation of physical ability of worker were done. The achieved results are shown bellow.1)Analysis of industrial accident and injuryThe relation between the age of workers and the accidents incidence ratio was analyzed, and in addition the working environment indexes that seem to become factors of Heat Stroke were measured. From the analysis age-accidents incidence relation shows bathtub type tendency, and the ratio of workers belong high age group and dangerous increases, so the necessity of safety programs for them are clarified. As for Heat Stroke, it was found that the number of accidents were increases when the temperature exceeds 30℃. And it was shown that works on the ground part were dangerous. Furthermore, a method of calculating WBGT that was able to be pre … More sumed on the site from a temperature and relative humidity was proposed.2)Analysis of physical stabilityBMI (Body Mass Index) calculated according to the height and weight was adopted as an index of the body. Afterwards, it newly proposed the index (It was recorded as L-value) obtained from tracks at the load center of foot bottom as an index that evaluated stability, and the stability of the physical stability was evaluated. It was confirmed that BMI and L-value are useful to evaluate the physical stability of working in construction sites, because from the experiment result BMI and L value were different when in walking in slope or carrying heavy load.3)Investigation of worker's physical functionsFrom the survey and the analyzed results of 1,010 total workers, it was found that the tendency to the blood pressure had no difference between workers and general people, muscular power of workers was higher than general people and high age group was more same as this tendency. The physical balance ability of workers was lower than general people, and the influence of work was expected. Moreover, the peak seemed on age group that was higher than general people, and for rise of physical ability cause by work. The number of workers who answered suffered lumbago were 226, and these cases seemed by the compensable occupational disease chronic lumbagos that did not correspond. In each kind of construction works, there were a lot of people who suffered lumbago that constant posture like the plumbing, and the roof construction, etc. was kept and they were occupational categories of working occupational category, reinforced concrete construction, and formwork, etc. to which the weight thing was transported.

本研究通过对建筑工地作业人员的身体稳定性进行实验和检测，对建筑工地的工伤事故进行分析，并对建筑工地作业人员的体能状况进行调查。主要研究结果如下：1）工伤事故分析了工人年龄与工伤事故发生率的关系，并对可能成为中暑因素的作业环境指标进行了测定。从年龄-事故发生率关系的分析来看，呈现出浴缸式的发展趋势，高年龄组和危险性工人的比例增加，说明了对他们进行安全规划的必要性。至于中暑，当温度超过30℃时，发现事故数量增加。结果表明，地面部分的工作是危险的。此外，还提出了一种计算WBGT的方法，该方法能够用于预测 ...更多信息 2）身体稳定性分析采用根据身高和体重计算的BMI（身体质量指数）作为身体指标。之后，新提出了从足底负荷中心处的轨迹获得的指标（记为L值）作为评价稳定性的指标，并对物理稳定性的稳定性进行了评价。从实验结果可以看出，在斜坡上行走和负重时，BMI和L值是不同的。3）工人身体机能调查通过对1,010名工人的调查和分析，结果发现，工人与一般人群的血压变化趋势无差异，工人的肌力高于一般人群，高年龄组更接近这一趋势。工人的身体平衡能力低于一般人群，工作的影响是可以预料的。此外，高峰出现在高于一般人的年龄组，以及工作引起的体能提高。回答患有腰痛的工人人数为226人，这些病例似乎与可补偿的职业病慢性腰痛不对应。在各种建筑工程中，有很多人遭受腰痛，他们保持着固定的姿势，如管道，屋顶建筑等，他们是工作职业类别，钢筋混凝土建筑和模板等的职业类别，重量的东西被运送到那里。少
