Cov Qauv Cia Khoom Siv Rau Kev Ua Haujlwm Hlau

Tsev Tsim Khoom Hlau
1. Lub luag haujlwm ntawm kev txhawb nqa ntawm cov kem: kom ntseeg tau tias qhov ruaj khov thiab qhov ntev ntawm lub tsev Hoobkas; ua kev txhawb nqa sab rau kem kom txiav txim siab qhov ntev ntawm kem sab nraud ntawm lub dav hlau thav duab; kom tiv taus cov khoom thauj kab rov tav ntev los ntawm lub tsev Hoobkas, feem ntau yog cov khoom thauj cua.
Txoj Cai Tsim: Thaum siv cov hlau puag ncig uas muaj cov hlau hla ua ib qho kev txhawb nqa yooj ywm, lub hauv paus ntsiab lus yog tias cov hlau puag ncig yuav tsum tau nruj (qhov degree ntawm kev nruj ntawm cov hlau puag ncig yog raug rau qee qhov kev nruj sab nraum lub dav hlau) kom nws tuaj yeem xa cov zog kab rov tav ntev. Tau kawg, yog tias nws tsis nruj, qhov no yuav cuam tshuam rau qhov kev nruj thiab kev ruaj khov ntawm cov qauv; raws li rau pes tsawg qhov kev txhawb nqa tau teeb tsa hauv ib chav tsev qauv, nws yog txiav txim siab los ntawm lub zog kab rov tav ntev, txoj kab uas hla ntawm cov hlau thiab txoj cai tsim qauv; qhov loj ntawm cov hlau puag ncig yog txiav txim siab los ntawm lub nra hnyav uas tau los ntawm kev txhawb nqa, ib qho yuav tsum meej yog tias qhov kev qhia tshwj xeeb tsis muaj kev txwv rau qhov sib piv ntawm cov hlau puag ncig nruj (tsis tas yuav xyuas qhov sib piv ntawm cov hlau puag ncig, tsuav yog lub peev xwm tensile tau ntsib).

5. Liang
Cov khoom uas tau txhawb nqa los ntawm cov bearings thiab feem ntau dais cov zog sab nraud thiab cov zog shear, thiab uas lawv qhov kev hloov pauv tseem ceeb yog khoov, hu ua beams.
1. Los ntawm qhov pom ntawm kev ua haujlwm, muaj cov nqaj hlau, xws li cov nqaj hlau hauv paus thiab cov nqaj hlau thav duab (cov nqaj hlau thav duab (KL) hais txog cov nqaj hlau uas txuas nrog cov kem thav duab (KZ) ntawm ob qho kawg, lossis txuas nrog phab ntsa shear ntawm ob qho kawg tab sis muaj qhov sib piv ntawm qhov siab ntawm cov nqaj hlau tsis tsawg dua 5m, thiab lwm yam, ua ke nrog cov khoom ntsug xws li cov kem thiab phab ntsa thauj khoom, tsim ib lub kaw lus qauv chaw; muaj cov nqaj hlau, xws li cov nqaj hlau nplhaib, lintels, cov nqaj hlau txuas, thiab lwm yam, uas ua haujlwm ua cov qauv tsis tawg, tiv taus av qeeg, thiab ruaj khov. (Cov nqaj hlau khi yog cov nqaj hlau khi uas txuas cov tswv cuab ntawm cov qauv. Lawv lub luag haujlwm yog ua kom muaj kev ncaj ncees ntawm cov qauv. Cov nqaj hlau khi feem ntau ua lub luag haujlwm ntawm kev txuas cov thav duab ib leeg kom ua rau lub tsev ruaj khov lossis ntev. Ntxiv nrog rau cov nqaj hlau khi, Nws yuav tsis dais lwm yam khoom thauj tsuas yog nws tus kheej lub nra hnyav thiab lub nra ntawm phab ntsa sab saud).
2. Raws li daim ntawv hla-seem, cov kab teeb tuaj yeem muab faib ua: cov kab teeb plaub fab, cov kab teeb T-zoo li, cov kab teeb hla-seem, cov kab teeb I-zoo li, cov kab teeb U-zoo li, cov kab teeb slotted, thiab cov kab teeb tsis sib xws.
3. Cov ntoo tuaj yeem muab faib ua: cov ntoo ru tsev, cov ntoo hauv pem teb, cov ntoo hauv av, thiab cov ntoo hauv paus raws li lawv qhov chaw nyob hauv ntau qhov chaw ntawm lub tsev. (Cov ntoo ru tsev yog cov khoom tseem ceeb hauv cov qauv ru tsev uas dais lub siab los ntawm purlins thiab ru tsev vaj huam sib luag.)
6. Cov Purlins:
Cov purlins tseem ceeb tau txuas thiab ntsia rau ntawm lub ru tsev thiab phab ntsa sab nraud cov qauv kem thiab beams, thiab cov purlins thib ob yog siv los txuas cov vaj huam sib luag ru tsev thiab phab ntsa sab nraud rau cov qauv yooj yim. Cov tsev qauv hlau niaj hnub feem ntau siv cov hlau C/Z-zoo li. Cov hlau Z-zoo li siv ua purlin ntawm lub tsev, uas muaj peev xwm dais tau zoo dua thiab yog ib qho khoom txhawb nqa sab hauv ntawm cov qauv hlau. Cov purlins tseem ceeb tau txuas thiab ntsia rau ntawm lub ru tsev thiab phab ntsa sab nraud cov qauv kem thiab beams, thiab cov purlins thib ob yog siv los txuas cov vaj huam sib luag ru tsev thiab siding rau cov qauv hauv paus.
7. Kev txhawb nqa Purlin:
Kev teeb tsa cov kev txhawb nqa purlin ntawm qhov kawg ntawm cov purlins uas yooj yim txhawb nqa lossis ntawm qhov sib tshooj ntawm cov purlins txuas ntxiv tuaj yeem tiv thaiv cov purlins kom tsis txhob tilting lossis twisting ntawm cov kev txhawb nqa. Cov kev txhawb nqa Purlin feem ntau yog ua los ntawm cov hlau kaum sab xis lossis cov phaj hlau. Qhov siab ntawm cov phaj ntsug yog li 3/4 ntawm qhov siab, thiab lawv txuas nrog cov purlins nrog bolts.
