建筑螺紋鋼筋里面可添加抗震鋼，若要是一般的住宅樓要用什么材質的鋼材鋼筋呢？濟鋼代理商公司的小編為您介紹一下。
Construction of rebar can be added to the seismic steel, if the general residential building to use what material steel, steel bar? Jinan Iron & Steel Co., Ltd.'s small series for you to introduce.
住宅樓用什么材質的螺紋鋼筋這還要根據我國自然地理條件的不同而采用不同。一般少發地震的地區，用的材質多是HRB335、HRB400E；高層建筑和地震多發地震基本上HRB400E、HRB500。

What kind of rebar is used in residential buildings, which should be different according to the natural geographical conditions of our country. Generally less earthquake areas, the use of materials are mostly HRB335, HRB400E; high-rise buildings and earthquakes, earthquakes are mostly HRB400E, HRB500.
如果房子的樓板是預制板的那么里面的螺紋鋼筋就是冷拔預應力筋， 通常在樓板內使用，做板底筋或板負筋，大跨度的板也用HRB400鋼筋做底筋和負筋，房子梁板柱采用什么鋼筋都是安全的，所以沒有必要了解是用什么螺紋鋼筋，房子出現危險很多原因是施工過程中的鋼筋構造要求達不到設計要求或使用了“瘦身鋼筋”造成的，很少是結構計算選型錯誤造成的。
If the house floor is prefabricated as rebar inside is drawn prestressed reinforcement, usually used in the floor, do the slab reinforcement or negative reinforcement plate, long span plate with HRB400 steel bars and end of negative reinforcement, reinforced by what Liang Banzhu house are safe, so there is no need to know is what is the structure of reinforced rebar, house construction process requirements to meet the design requirements or the use of thin steel caused by the risk of a lot of reasons, is rarely caused by the errors of calculation and selection of structure.
