建筑工程上還普遍使用二級鋼時，那在建房時，若很富有的話，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？
Construction is also widely used when the two grade steel, and that in the building, if it is rich, the construction of rebar can be added to the seismic steel, if the general residential building to use what material steel, steel bar?
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。鋼筋在混凝土中主要承受拉應(yīng)力。變形鋼筋由于肋的作用，和混凝土有較大的粘結(jié)能力，因而能更好地承受外力的作用。鋼筋廣泛用于各種建筑結(jié)構(gòu)、特別是大型、重型、輕型薄壁和高層建筑結(jié)構(gòu)。

What kind of rebar is used in residential buildings, which should be different according to the natural geographical conditions of our country. Steel bars are mainly subjected to tensile stress in concrete. Because of the function of rib and the greater bond ability of concrete, deformed steel bar can bear the effect of external force better. Reinforcement is widely used in a variety of building structures, especially large, heavy, light, thin-walled and high-rise structures.
如果房子的樓板是預(yù)制板的那么里面的螺紋鋼筋就是冷拔預(yù)應(yīng)力筋， 通常在樓板內(nèi)使用，做板底筋或板負(fù)筋，大跨度的板也用HRB400鋼筋做底筋和負(fù)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。
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.
