随着经济建设的迅速发展,目前,建筑钢材在市场上供不应求,在保证工程质量的前提下,建筑工程中可以从以下几个方面节约钢材。一、钢筋加工方面1.钢筋采用冷拉。钢筋冷拉是提高钢筋强度和硬度、发挥钢筋强度潜力的方法。通过冷拉,Ⅰ级钢筋一般可拉长7%～10%;Ⅱ、Ⅲ级钢筋一般可拉长3%～5%。冷拉后增加的钢筋长度有效地节约了钢筋。目前钢筋加工过程中的几个工序已经和钢筋冷拉结合在一起。比如通过冷拉进行钢筋调直、除锈和检验焊接质量。因此,钢筋冷拉具有综合效益。
With the rapid development of economic construction, at present, the supply of construction steel in the market is in short supply. Under the premise of ensuring project quality, steel products can be saved from the following aspects in construction projects. First, rebar processing 1. Rebar adopt cold drawing. Cold-drawn steel bars are a way to increase the strength and hardness of steel bars and to exert their strength potential. Through cold-drawing, grade I steel can generally be stretched by 7% to 10%; Grade II and grade III steel can generally be elongated by 3% to 5%. The increased length of the bars after cold drawing effectively saves the bars. Several processes in the current rebar machining process have been combined with cold-drawn steel bars. For example, straightening, rust removal and inspection of welding quality by cold drawing. Therefore, cold rolled steel has comprehensive benefits.
