However, the width of the removed components is different and the height from the ground is different. The traditional temporary support has a fixed height and width and cannot be adjusted according to the actual situation on site. This requires the temporary support to be welded, lengthened, cut or remade after the height and width are actually measured on site, which seriously affects the progress of on-site construction work, and also increases the cost of material production and reduces the reuse rate.
