在建房時，建筑工程普遍使用二級鋼時就很富有了，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(zhì)的鋼材鋼筋呢？
In the building, the general use of two steel construction project is very rich, the construction of rebar can be added to the earthquake resistance of steel, if the general residential building materials to use what the steel bar?
一般住宅樓要用什么材質(zhì)的螺紋鋼筋？
General residential building materials to use what the rebar?
住宅樓用什么材質(zhì)的螺紋鋼筋這還要根據(jù)我國自然地理條件的不同而采用不同。一般少發(fā)地震的地區(qū)用的材質(zhì)多是HRB335、HRB400E；高層建筑和地震多發(fā)地震基本上HRB400E、HRB500。
What kind of material used in residential buildings, which will be based on the different nature and geographical conditions of china. In general, the material used in the area of less earthquakes is mostly HRB335, HRB400E; high-rise buildings and earthquakes are basically HRB400E, HRB500.
可以肯定的說，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(nèi)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(xiàn)危險很多原因是施工過程中的鋼筋構(gòu)造要求達不到設(shè)計要求或使用了“瘦身鋼筋”造成的，很少是結(jié)構(gòu)計算選型錯誤造成的。
To be sure, 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 house slab column what are safe. So there is no need to know what is the rebar, house is steel construction in the 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.
