Hars nqus seismic lub zog los ntawm kev sib tw, txo kev phom sij hauv av qeeg. Lawv lub teeb yuag txo qis hauv cov rog, tsis zoo li brittle qheb kab teeb. Kev sib txuas nrog cov qhov zuaj qhov tso cai tso cai txav, thaum pob zeb ua kom yuav tsum muaj nuj nqis cuam tshuam. Retrofitting cov txheej txheem uas twb muaj lawm nrog H tw kis tau nrawm dua thiab muaj kev lag luam. Nyiv cov seismic cov lej hnyav ntxiv cov hlau h cis rau high-nce.
Dab tsi yog qhov tseem ceeb ntawm h piles (hp duab) hauv lub hauv paus nruab nrab?
H piles (piv txwv li, HP 310x125) hloov cov khoom thauj los ntawm cov av tsis muaj zog mus rau qhov ruaj khov. Lawv cov lej siab modulus tiv thaiv dabtsi yog thaum lub sijhawm tsav tsheb. Ntau yam nyob rau hauv skyscrapers thiab choj, lawv txo kev pheej hmoo muaj kev ruaj ntseg. Corrosion-resistant txheej zoo li epoxy tau thov rau kev ntev. HP pawg tuaj yeem raug faib rau qhov tob tshaj 50 meters.
Yuav ua li cas xaiv ntawm universal Beams (UB) thiab H Beams rau ib qhov project?
UB Beams (piv txwv li, UB 203 x133) muaj cov roj teeb sib zog rau cov sib zog, thaum hobs (piv txwv li kub 300) muaj cov khaub ncaws tuab rau kev siv zog. UB Beams yog pheej yig dua rau cov thav ntawv nyob, whereas h cis su teeb chav tsev. Xav txog kev txiav txim siab ntev-H BARS Excel tshaj 10 meters. Nco ntsoov xyuas cov cim hauv tsev hauv zos rau cov khoom pom zoo.
Cov hau kev tua hluav taws rau h nqaj hauv cov tsev lag luam?
Intumescent pleev xim rau hauv qab kub, insulating nqaj rau 60-120 feeb. QHOB ENCASEMENT yog tus nqi-ua tau zoo tab sis ntxiv qhov hnyav. Cov pob zeb me me muab kev tiv thaiv lub cev. Hluav taws ua cav sib cais txiav txim siab txog qhov yuav tsum tau kub tiv thaiv (FRR). Kev tshawb xyuas ib txwm ntseeg ntseeg tias lub vas tsho tseem ua kev tsim kho tom qab kev tsim kho.
Vim li cas S355jR H Beams nyiam rau cov ntawv thov kev ntxhov siab?
S3555jr muaj ib qho 355 MPa paib lub zog, 50% siab dua S235JR, nrog kev cuam tshuam zoo ntawm cov khoom kub. Nws cov tshuaj muaj kuab lom (tswj cov pa roj carbon \/ manganese) txhim kho weldability. Cov nqaj no yog siv rau hauv cov crane ntsia thiab ntug hiav txwv Rigs. Cov ntawv pov thawj muaj cov ntawv xeem uas yuav tsum muaj. Tus nqi them tus nqi yog muaj kev ncaj ncees rau cov qauv tseem ceeb.
