Lub tawb nqa khoom yog tsim los rau kev tsim cov pob zeb ua vaj huam sib luag monolithic. Cov cuab yeej tso cai rau koj muab rigidity rau cov qauv, noj ntawm tensile thiab dabtsi yog khoov loads. Lub tawb nqa khoom kuj tseem siv rau kev tsim lub hauv paus ntawm lub tsev thiab rau kev tsim cov pob zeb ua pob zeb.
Muaj ntau yam khoom siv rau kev txhim kho phab ntsa, tsim txoj kev, teeb tsa lub hauv paus thiab ua cov khoom siv pob zeb. Nyob ntawm txoj kab uas hla thiab qhov chaw ntawm cov pas nrig, cov thav ntawv hlau muab faib ua lub teeb thiab hnyav.
Tib lub sijhawm, nyob ntawm cov duab, cov qauv tau muab faib ua kev txhawb nqa meshes, tiaj tus thiab spatial. Lawv tuaj nyob rau hauv round, triangular, T-puab thiab square duab. Hom thav duab feem ntau yog nyob ntawm tus tsim ntawm cov khoom. Yog li ntawd, ib lub tawb spatial reinforcing tawb tuaj yeem sib sau los ntawm ntau hom ca. Ntxiv mus, qhov kev hloov pauv no tuaj yeem ua tiav ntawm qhov chaw tsim kho, yog li txo nqi tsheb thauj mus los.
Hnub no kev tsim cov qauvtau tsiv los ntawm cov chaw tsim kho mus rau lub Hoobkas tsim cov khw. Qhov no tso cai rau koj kom nce lub zog thiab zoo ntawm cov khoom, txuag lub sijhawm ntawm kev sib dhos. Kev txhawb nqa cages ntawm cov tsev sawv cev rau kev sib txuas lossis welded qauv ntawm cov pas nrig thiab lwm yam khoom. Nyob rau hauv cov xwm txheej ntau lawm, kev siv zog ntxiv yog hloov los ntawm kev sib cuag vuam.
Qhov khoob rau kev tsim cov khoom yog hlau rods, uas (nyob ntawm tus tsim) yog ntsia transversely thiab longitudinally. Qib steel yog txiav txim los ntawm cov ntaub ntawv tsim. Nyob ntawm qhov kub thiab txias, cov hlau yog siv uas tsis raug rau qhov txias brittleness.
Yog tias cov khoom yuav ua haujlwm ntawm qhov kub qis dua 30, ces steel qib VSt5ps2 yog siv. Hauv cov cheeb tsam sab qaum teb, rau kev tsim lub tawb nqa khoom, cov pas nrig ua los ntawm qib 35GS cov khoom ntawm chav kawm A3 yog siv. Tsis tas li ntawd, qhov degree ntawm weldability ntawm steel yuav tsum tau muab rau hauv tus account. Nws yog txwv tsis pub koom nrog cov khoom siv cua sov-hardened reinforcing thiab high-strength hlau, vim vuam yuav poob lub zog ntxiv.
Txoj kev siv zog rau kev tsim cov pob zeb ua vaj huam sib luag yog muab faib ua cov hlau tsis yog hlau thiab hlau raws li cov khoom siv. Raws li cov khoom siv thev naus laus zis - rau cov pas nrig kub kub (txoj kab uas hla ntawm 6 txog 90 hli) thiab cov xaim xaim txias txias (txoj kab uas hla ntawm 3 mus rau 8 hli). Cov khoom yog tsim nyob rau hauv daim ntawv ntawm high-lub zog thiab zoo tib yam hlau, raws li zoo raws li cov strands thiabtxhawb hlua.
Lub tawb txhawb nqa yog ua los ntawm ib ntus lossis puag ncig du profile. Nyob rau hauv thawj rooj plaub, lub reinforcement muaj ib tug xam qhov chaw, uas ua rau nws muaj peev xwm mus cuag tau zoo adhesion rau pob zeb. Los ntawm lub hom phiaj, muaj cov qauv tsim los ntawm kev ua haujlwm ntxiv dag zog, uas pom tau tias feem ntau tensile stresses, tis, tsim kom sib npaug faib cov khoom nruab nrab ntawm cov pas nrig, nrog rau kev sib txuas, siv los sib sau ua ke.
