钢筋笼通常在现场加工组装。若是现场作业场地狭窄加工有困难,作业效率有显著降低时,可在工场或其他适当场所加工。有时工场加工更为经济的也有。在任何情况钢筋笼在移动或浇筑中都要求不能变形,必须制作坚固。一般对一个筑造单元组装成一个笼放进沟槽,也有由现场条件限制不得不进分割的情况也有。在这种情况,须使主筋搭接(Overlap)筑造,由于技术进步对上下笼已采用新的连结方法(见下面构造接手)。 Reinforcing cages are often assembled and machined on site. If the site is difficult to narrow the processing site, operating efficiency significantly reduced, the workshop or other appropriate place processing. Sometimes the workshop is more economical. In any case, reinforced cages are required to not be deformed during movement or pouring and must be made strong. A building unit is generally assembled into a cage into the trench, there are also restrictions on site conditions had to split into the case there. In this case, the main reinforcement must be overlapped (Overlap) construction, because of technological progress on the cage has adopted a new method of connection (see the following structure to take over).
