一震就散、一散就倒的房子使用了抗震鋼筋怎么還會(huì)倒,哦,是震極大的事?其實(shí)震極大也是一方面,還有一方面是沒有做好鋼筋混凝土的施工,偷工減料,能減就減,能少就少,這樣的房屋能經(jīng)的起抗震那才奇了怪。
How can a house that breaks up and falls down after an earthquake fall when it uses seismic reinforcement bars? Oh, it's a great earthquake? In fact, the tremendous earthquake is also on the one hand, and on the other hand, there is no good construction of reinforced concrete, Jerry work, can reduce, can reduce, can be less, such a house can withstand the earthquake that is strange.
像我國四川就是高發(fā)地震帶,自建房屋要知道鋼筋有哪些級(jí)別,哪種級(jí)別的抗震鋼筋更合適,并不是鋼筋越多而且越粗就越好,這遠(yuǎn)遠(yuǎn)不夠的。就農(nóng)村自建房而言,鋼筋級(jí)別應(yīng)選擇三級(jí)鋼筋HRB400以上,也就是鋼筋的屈服強(qiáng)度要大于400MPa。
For example, Sichuan is a high-frequency seismic zone in China. It is not enough for self-built houses to know what grades of steel bars are and which grades of anti-seismic steel bars are more suitable. The more and thicker the steel bars, the better. As far as rural self-built houses are concerned, the grade of reinforcement should be higher than HRB400, that is to say, the yield strength of reinforcement should be greater than 400 MPa.
要求房屋抗震烈度為7度,那一定要保證房屋建好后在7度地震以下主體不會(huì)被破壞。建房子用抗震鋼筋,說白了就是在自然災(zāi)難面前多為你和家從爭取更長的斷裂時(shí)間,如果普通的鋼筋,延伸性、抗震性都達(dá)不到抗震鋼筋的標(biāo)準(zhǔn),普通鋼筋會(huì)直接斷掉或是斷裂時(shí)間很短,你和家人的人身機(jī)率會(huì)降到很低。目前三級(jí)抗震用鋼筋是我國常用且用量大的建筑鋼材,截止到2017年7月底,三級(jí)鋼筋12-14mm現(xiàn)貨市場(chǎng)為3810元/噸,規(guī)格18mm三級(jí)螺紋鋼為3760元/噸,25mm的三級(jí)鋼在3740元/噸,28-32mm HRB400E螺紋鋼市場(chǎng)價(jià)為3770元/噸。
The seismic intensity of the building is required to be 7 degrees, which must ensure that the main body of the building will not be destroyed after the completion of the 7 degrees earthquake. Build a house with anti-seismic steel bars, in other words, in the face of natural disasters for you and your family to fight for a longer breaking time, if ordinary steel bars, extensibility, seismic resistance are not up to the standard of anti-seismic steel bars, ordinary steel bars will be directly broken or broken for a very short time, you and your family's personal safety probability will be reduced to very low. At present, the three-grade aseismic reinforcing steel bar is commonly used and used in our country. By the end of July 2017, the spot market price of the three-grade reinforcing steel bar 12-14mm is 3830 yuan/ton, the price of the standard 18mm three-grade screw steel is 3760 yuan/ton, the price of the 25 mm three-grade steel is 3740 yuan/ton, and the market price of the 28-32mm HRB400E screw steel is 3770 yuan/ton.
