单层工业厂房施工中,需在大型屋面板底部勾缝喷浆、在桁架上安装动力线和照明线等各道工序。常规施工方法是利用天车或搭满堂红脚手架。唐山轻机厂工程车间建成时既无天车,也无材料搭满堂红脚手架,在这种情况下,我们试制了一台简易天车进行施工。一、结构型式简易天车必须坚固,刚度好,拆装灵活方便,跨度可根据车间情况随时调整,重量轻,推动轻便。我们在结构设计上分(1)轨道支架,(2)天车主梁,(3)联接支架三部分进行设计。简易天车采用双梁天车型式,考虑到天
In the construction of a single-story industrial plant, various procedures such as spraying the slurry at the bottom of large roof panels, installing power lines and lighting lines on the truss are required. The conventional construction method is to use a crane or full-red scaffold. When the engineering workshop of Tangshan Light Machine Factory was completed, there was no overhead crane and no red scaffolding for materials. In this case, we tried a simple crane for construction. First, the structure type simple crane must be strong, good rigidity, flexible and convenient disassembly, the span can be adjusted at any time according to workshop conditions, light weight, and promote light. In the structural design, we divide the design of the (1) rail bracket, (2) the main crane beam, and (3) the joint bracket. Simple overhead crane adopts double beam sky model, taking into account the days
