调整屋架的垂直度,过去多采用在相邻两榀屋架上绑扎杉木杆或楠竹的方法,既费工时,也不易控制安装质量。近几年来,我俏采用了由工长李国大和钳工李克静等人提出的稠整工具(图1),克服了上述缺点,效果很好。最近,我们在某厂房的屋架安装中,由 In order to adjust the verticality of the truss, the method of tying the cedar or bamboo in the adjacent two trusses was used in the past. It was time-consuming and difficult to control the installation quality. In recent years, I have adopted a thickening tool proposed by the foreman Li Guoda and the fitter Li Kejing et al. (Figure 1), which overcomes the above shortcomings and works well. Recently, we were in the truss installation of a factory building.
