采用高强度预应力钢筋可使建筑工程节约投资、降低成本、减少钢材的消耗。目前我国用于预应力混凝土结构的高强钢材有如下三种:钢筋、钢丝、钢绞线。其中钢筋的生产设备较简单,易于大量生产,价格最低。在不增加合金元素的条件下,采用“调质热处理”的方法,是进一步提高钢筋强度的有效途径。热处理钢筋具有设备简单、投资少、投产快、生产效率高的优点,经过热
The use of high-strength prestressed steel bars can save construction investment, reduce costs, and reduce steel consumption. At present, there are three types of high-strength steel used in prestressed concrete structures in China: steel bars, steel wires, and steel strands. Among them, the steel production equipment is relatively simple, easy to mass produce, and the lowest price. Under the condition of not increasing the alloying elements, the method of “refining heat treatment” is an effective way to further increase the strength of steel bars. Heat-treated steel bars have the advantages of simple equipment, low investment, quick production, and high production efficiency.
