这项研究的主要目的是通过应用计算机化的OWAS方法，找出在建筑工地执行锤击任务时最有问题的姿势，并提出改进工作方法和工作场所的建议。来自三家建筑公司的18名建筑工人参加了实地研究，平均年龄为41.6岁。在两个月期间观察到的锤击任务包括屋顶板、混凝土模板准备、夹紧支撑支撑、组装屋顶框架、屋顶连接、遮蔽物模板准备和固定叉夹。工人们使用了三种不同类型的锤子，包括小菲斯卡锤、菲斯卡建筑锤和火箭锤。在所有观察中，最常见的不良工作姿势是屋顶连接(占任务内所有观察的12.4%)，其次是混凝土模板准备(8.6%)，以及屋顶框架的建造(7.5%)。总体而言，在分析的593种不同姿势中，工人在各种锤击任务中所采用的姿势中，总共有7.8%被归类为I11或IV类OWA，表明这些姿势应该尽快或立即纠正。用于姿势数据分析的计算机化OWAS方法被证明是一种非常有用的方法，可以减少动态锤击任务的姿势负荷，并允许有效地应用原始的OWAS方法。
The main objectives of this study were to identify the most problematic postures in hammering tasks performed at building construction sites through application of the computerized OWAS method, and to develop recommendations for improvement of working methods and workplaces. Eighteen construction workers, with mean age of 41.6, from three construction companies participated in the field study. The hammering tasks observed during the two-month period included roof boarding, concrete form preparation, clamping support braces, assembling roof frames, roof joisting, shelter form preparation, and fixing fork clamps. Three different types of hammer, including a small Fiskar's hammer, a Fiskar's construction hammer, and a Rocket hammer, were used by the workers. Of all the observations, poor working postures were observed most frequently in roof joisting (12.4% of all observations within the task), followed by concrete form preparation (8.6%), and construction of frames for the roof (7.5%). Overall, out of 593 different postures analysed, a total of 7.8% of postures adopted by the workers during various hammering tasks were classified into OWAS categories Ill or IV, indicating that these postures should be corrected either soon or immediately. The computerized OWAS method for postural data analysis proved to be a very useful way to reduce postural load of dynamic hammering tasks, and allowed for efficient application of the original OWAS method.
