现浇楼面主次梁或井字梁交接处的钢筋错综复杂,主、次梁上部纵向钢筋、板中负筋及其分布筋的排列与放置常使钢筋工感到为难。现提出一个式样供参考,见图1、2。1.在板中双向负筋重叠区不另加负筋的分布筋,以外部分的负筋分布筋只伸入重叠区一个搭接长度。2.次梁上部纵筋放在主梁上部纵筋之上,并与之绑扎;板中与主梁
The reinforcements at the intersection of the main and secondary beams or the wellhead beams at the cast-in-place floor are intricate, and the arrangement and placement of the longitudinal reinforcements on the upper and lower main beams, the negative reinforcements in the plates, and their distribution tends to make it difficult for the steelworkers. A model is proposed for reference, see Fig. 1. 2. 1. In the plate, the two-way negative reinforcement overlap area does not add negative reinforcement ribs, and the negative reinforcement distribution ribs only extend into the overlapping area one lap length. 2. The upper beam of the secondary beam is placed on the upper longitudinal bar of the main beam and tied with it; the middle plate and the main beam
