Hom ntawmcov hlau ntawv pawg
Raws li "Cov Hlau Kub Dov Sheet Pile"(GB∕T 20933-2014), cov hlau kub dov pawg muaj peb hom, cov hom tshwj xeeb thiab lawv cov npe code yog raws li nram no:U-hom steel sheet pile, lub npe code: PUZ-hom steel sheet pile, lub npe code: PZ linear steel sheet pile, lub npe code: PI Nco ntsoov: qhov twg P yog thawj tsab ntawv ntawm steel sheet pile hauv lus Askiv (Pile), thiab U, Z, thiab kuv sawv cev rau cov duab ntawm steel sheet pile.
Piv txwv li, feem ntau siv U-hom steel sheet pile, PU-400X170X15.5, tuaj yeem nkag siab tias yog 400mm dav, 170mm siab, 15.5mm tuab.
Z-hom steel sheet pile
U-hom steel sheet pile
Vim li cas nws tsis yog hom Z lossis hom ncaj tab sis hom U uas siv ntau hauv kev tsim kho? Qhov tseeb, cov yam ntxwv kho tshuab ntawm hom U thiab hom Z yeej zoo ib yam rau ib qho, tab sis qhov zoo ntawm pawg hlau U yog pom tseeb hauv kev ua haujlwm sib koom ua ke ntawm ntau pawg hlau U.
Los ntawm daim duab saum toj no, nws tuaj yeem pom tias qhov khoov ntawm ib 'meter' ntawm U-hom steel sheet pile loj dua li ntawm ib qho U-hom steel sheet pile (qhov chaw nruab nrab ntawm lub axis hloov pauv ntau) tom qab U-hom steel sheet pile raug tom ua ke.
2. Cov khoom siv hlau
Qib hlau Q345 raug tshem tawm! Raws li tus qauv tshiab "Low Alloy High Structural Steel" GB / T 1591-2018, txij li Lub Ob Hlis 1, 2019, qib hlau Q345 raug tshem tawm thiab hloov mus rau Q355, sib raug rau EU tus qauv S355 qib hlau.Q355 yog cov hlau tsis tshua muaj zog nrog lub zog tso zis ntawm 355MPa.
