Cov Tswv Yim Tsim Qauv Hlau Rau Cov Tsev Lag Luam

Nyob rau hauv kev hloov pauv dav dav ntawm kev lag luam kev tsim kho mus rau kev txhim kho ntsuab dua thiab kev lag luam ntau dua, cov tsev prefab hlau—ua cov ntaub ntawv tseem ceeb rau cov chaw tsim khoom lag luam, cov tsev lag luam, thiab cov chaw zoo sib xws—tab tom ntsib kev thov ua lag luam nce ntxiv.

Kev ua haujlwm kom haum yog lub hauv paus ntsiab lus tseem ceeb hauv kev tsim qauv ntawm cov tsev tsim uaTus qauv tsim yuav tsum sib phim nrog cov txheej txheem tsim khoom thiab cov txheej txheem ua haujlwm ntawm lub tuam txhab kom ntseeg tau tias qhov chaw hauv tsev phim cov kev xav tau ua haujlwm.

Ntawm ib sab tes, qhov chaw ntawm lub Hoobkas yuav tsum tau npaj kom raug raws li qhov loj ntawm cov kab ntau lawm, cov kev xav tau ntawm kev teeb tsa khoom siv, thiab cov kev thauj khoom. Qhov no suav nrog kev txiav txim siab qhov ntev ntawm lub tsev, qhov sib nrug ntawm cov kem, qhov siab ntawm zaj dab neeg, thiab lub peev xwm thauj khoom ntawm crane girder. Piv txwv li, cov chaw tsim khoom siv tshuab hnyav feem ntau xav tau qhov ntev loj (feem ntau yog 24–36 meters), qhov siab pom tseeb (8–12 meters), thiab cov tshuab crane nrog lub peev xwm nqa tau 30–50 tons. Qhov sib piv, cov chaw sib dhos hluav taws xob sib dhos tuaj yeem siv qhov sib nrug ntawm cov kem me dua, ua kom zoo dua kev siv qhov chaw, thiab ntxiv cov plag tsev mezzanine rau cov chaw ua haujlwm lossis cov tsev cia khoom hlau.

Ntawm qhov tod tes, yuav tsum tau coj mus rau hauv tus account cov kev cai tshwj xeeb ntawm cov txheej txheem ntau lawm sib txawv. Cov chaw tsim tshuaj xav tau kev tiv thaiv xeb zoo dua, xws li cov txheej fluorocarbon lossis cov khoom siv hlau galvanized. Kub siab kev tsim kho vaj tse hlau xav tau lub qhov rais saum ru tsev uas muaj qhov cua thiab cov txheej rwb thaiv cua sov kom tiv thaiv cov hlau kom tsis txhob lwj vim qhov kub thiab txias hloov pauv. Lub sijhawm no, cov chaw ua haujlwm huv si xav tau kev tswj hwm nruj rau kev kaw cov pob qij txha ntawm cov qauv hlau kom txo cov plua plav thiab xyuas kom meej tias qhov chaw tsim khoom ua tau raws li cov qauv kev huv.

Kev tsim qauv kev nyab xeeb ntawm prefab rhiav steel qauv yuav tsum tau hais txog peb qhov tseem ceeb - kev nyab xeeb ntawm kev thauj khoom, kev nyab xeeb hluav taws, thiab kev nyab xeeb ntawm av qeeg - kom ntseeg tau tias muaj kev ruaj khov ntawm cov qauv thoob plaws lub neej ntawm lub tsev.

Hais txog kev nyab xeeb ntawm lub nra hnyav, kev suav cov qauv tsim kom raug yog qhov yuav tsum tau ua kom xaiv cov qib hlau tsim nyog thiab ua kom zoo dua cov ntsiab lus txuas. Piv txwv li, kev sib txuas ruaj khov feem ntau raug siv ntawm cov pob qij txha beam-column kom ntseeg tau tias muaj kev hloov pauv lub zog zoo. Cov ntsia hlau tiv taus shear tau ntxiv rau kev sib txuas ntawm crane girders thiab steel kem kom tiv thaiv kev xoob los ntawm kev co vim yog lub nra hnyav.

Kev nyab xeeb hluav taws yog ib qho ntawm cov teeb meem tseem ceeb ntawm cov qauv hlau thiab yuav tsum tau daws los ntawm kev sib xyaw ua ke ntawm kev tiv thaiv hluav taws tsis siv neeg thiab kev tiv thaiv hluav taws kubRau kev tiv thaiv tsis siv neeg, cov txheej tiv thaiv hluav taws kub tau siv rau cov hlau - cov txheej nyias nyias yog qhov tsim nyog rau thaj chaw uas muaj qhov kub txog li 500 ° C, thaum cov txheej tuab siv rau hauv thaj chaw muaj kev pheej hmoo hluav taws kub. Xwb, cov laug cam tiv thaiv hluav taws kub tuaj yeem siv los kaw cov hlau, xyuas kom meej tias cov qauv tswj nws lub peev xwm thauj khoom tsawg kawg 1.5 teev thaum muaj hluav taws kub. Rau kev tiv thaiv nquag, cov tshuab txau dej tsis siv neeg thiab cov khoom siv ceeb toom hluav taws kub yuav tsum tau teeb tsa kom raug kom luv lub sijhawm teb hluav taws thiab tswj kev kis hluav taws kub kom zoo.

Kev nyab xeeb ntawm av qeeg yuav tsum tau tsim raws li qhov muaj zog ntawm qhov chaw ntawm lub tsev thaum av qeeg. Qhov no suav nrog kev ua kom zoo dua qhov kev faib tawm ntawm cov qauv ruaj khov thiab siv cov ntsiab cai tsim ntawm 'cov kem muaj zog, cov ntoo tsis muaj zog' thiab 'cov pob qij txha muaj zog, cov tswv cuab tsis muaj zog.' Tsis tas li ntawd, cov khoom siv tshem tawm lub zog lossis cov khoom siv damping tuaj yeem ntsia tau ntawm cov hauv paus kem kom txo qhov kev xa hluav taws xob ntawm av qeeg thiab txhim kho lub tsev tiv taus av qeeg tag nrho.
