Cov yam ntxwv tseem ceeb ntawm kev tsim qauv

Hlau Truss Jib - Tsim los rau Kev Tiv Thaiv Cua

Lub jib siv cov qauv truss lattice (cov thav duab peb ceg lossis plaub ceg welded los ntawm cov hlau qauv), uas muaj:

1. Kev tsim kho sib dua — qhov hnyav qis dua piv rau cov qauv tsim uas muaj lub thawv

2. Qhov sib piv ntawm lub zog thiab qhov hnyav - cov khoom siv sib sau ua ke hauv cov chord thiab diagonals rau kev faib khoom zoo tshaj plaws

3. Txo qhov cua ntsawj — cua ntws los ntawm qhov qhib truss, txo cov zog sab nraud

4. Cov nqi khiav lag luam qis dua — xav tau cov khoom siv cua me dua

5. Kev saib xyuas yooj yim — cov qauv qhib tso cai rau kev kuaj pom, nkag mus rau sab hauv rau txheej, thiab cov dej ntws ntuj kom tiv thaiv kev xeb

Hauv cov ntawv thov chaw nres nkoj uas cov crane dav dav feem ntau tshaj 60 meters, cov truss main girders tsuas yog hnyav 40% txog 55% ntawm cov qauv tsim sib npaug ntawm lub thawv-girder. Qhov kev txo qhov hnyav no txhais tau tias cov log tsheb tsawg dua, txo cov nqi khiav thiab lub hauv paus, thiab txhim kho kev txav mus los ntawm crane.
