矩形断面钢筋混凝土构件(如柱、梁、桩等)一般用焊接的空间骨架配筋,这些空间骨架是由平面骨架与横向钢筋焊在一起而形成的。平面骨架在效率很高的设备上制作,可是把它们连接成空间骨架却很费工。不仅如此,空间骨架占有很大的体积,以致不能合理地利用运输设备和堆放场所。 Rectangular section reinforced concrete members (such as columns, beams, piles, etc.) are generally reinforced with welded space skeletons, which are formed by the planar framework and transverse reinforcement. The plane skeletons are made on highly efficient equipment, but connecting them into a space skeleton is very laborious. Not only that, the space skeleton occupies a large volume, so that it is impossible to make reasonable use of transportation equipment and stacking sites.
