Amamodeli wenqwaba yeshidi lensimbi ye-lasen nezinto zokwakha

 

Izinhlobo zeizinqwaba zeshidi lensimbi
Ngokuvumelana ne "Inqwaba Yeshidi Leshidi Eligoqiwe Elishisayo” (GB∕T 20933-2014), inqwaba yeshidi eligoqiwe elishisayo lihlanganisa izinhlobo ezintathu, izinhlobo ezithile kanye namagama ekhodi yazo kanje:Inqwaba yeshidi lensimbi yohlobo lwe-U, igama lekhodi: inqwaba yeshidi lensimbi yohlobo lwe-PUZ, igama lekhodi: PZ linear steel sheet pile, igama lekhodi: PI Qaphela: lapho u-P enguhlamvu lokuqala lwenqwaba yeshidi lensimbi ngesiNgisi (Inqwaba), kanye no-U, Z, no-I melela ukuma kwe-cross-sectional yenqwaba yeshidi lensimbi.

 

Isibonelo, inqwaba yeshidi lensimbi evame ukusetshenziswa kakhulu ye-U, i-PU-400X170X15.5, ingaqondwa njenge-400mm ububanzi, 170mm ukuphakama, 15.5mm ubukhulu.

Inqwaba yeshidi lensimbi yohlobo lwe-U

 

Kungani kungelona uhlobo lwe-Z noma oluqondile kodwa uhlobo lwe-U oluvame ukusetshenziswa kubunjiniyela? Eqinisweni, izici zemishini zohlobo lwe-U nohlobo lwe-Z ngokuyisisekelo ziyefana koyedwa, kodwa inzuzo yenqwaba yeshidi lensimbi yohlobo lwe-U ibonakala esenzweni esihlanganyelwe sezinqwaba zeshidi lensimbi lohlobo lwe-U.

 

Kusukela kulesi sithombe esingenhla, kungabonakala ukuthi ukuqina kokugoba imitha ngayinye yomugqa wenqwaba yeshidi lensimbi yohlobo lwe-U inkulu kakhulu kunenqwaba yeshidi lensimbi yohlobo olulodwa lwe-U (indawo ye-eksisi engathathi hlangothi igudluzwa kakhulu) ngemuva kwe-U- inqwaba yeshidi lensimbi ilunywa ndawonye.
2. Impahla yenqwaba yeshidi lensimbi
Ibanga lensimbi Q345 likhanseliwe! Ngokwezinga elisha elithi “Low Alloy High Strength Structural Steel” GB/T 1591-2018, kusukela ngo-February 1, 2019, izinga lensimbi le-Q345 likhanseliwe futhi lashintshwa laba yi-Q355, elihambisana ne-EU standard S355 grade. I-Q355 iyizinga elijwayelekile insimbi ye-low-alloy high-strength enamandla okukhiqiza angu-355MPa.
