Tus nqi -Kev Pabcuam ntawm S690Q kub dov steel phaj hauv Choj Qhov hnyav

Hauv kev tsim choj choj, cov khoom siv hnyav ncaj qha cuam tshuam rau kev tsim choj, kev tsim kho nyuaj, thiab lub neej - nqi mus ncig.S690Q kub dov steel phaj tau dhau los ua cov khoom siv tseem ceeb rau kev txo qhov hnyav vim nws qhov zoo ntawm qhov muaj zog tshwj xeeb (lub zog / ntom) - piv nrog cov tib yamcarbon steel phaj, nyob rau hauv tib lub load-cov kabmob muaj peev xwm,S690Q kub dov steel phajtuaj yeem ua tiav qhov hnyav txo qhov hnyav ntawm 30%, thiab txo qis tus nqi.

cas

Ntu txuas txuas ntawm tus hla- txoj haujlwm choj tus dej yog tsim los sivQ345B kub dov steel phaj(yield zog 345MPa), nrog lub web phaj thickness ntawm 32mm thiab flange phaj thickness ntawm 40mm; tom qab ntawd, nws tau hloov nrogS690Q kub dov steel phaj, lub vev xaib phaj tuab tau hloov kho mus rau 22 hli, thiab flange phaj thickness mus rau 28 hli, thaum ua kom seem khoov modulus tsis hloov. Qhov hnyav, tus nqi tsim kho, thiab kev ua haujlwm thiab kev saib xyuas tus nqi ntawm ob lub tswv yim tau muab piv.

Qhov hnyav txo qhov cuam tshuam thiab txo tus nqi ncaj qha

Khoom hnyav: Rau ib qho 12-meter-ntev choj lub thawv girder, qhov hnyav ntawm Q345B tswvyim yog 18.6 tonnes, thiab qhov hnyav ntawm qhovS690Q kub dov steel phajLub tswv yim yog 13.0 tonnes, nrog qhov hnyav txo ntawm 5.6 tonnes thiab qhov hnyav txo ntawm 30.1%. Muab xam los ntawm tus nqi ntawm cov khoom siv steel (Q345B yog li CNY 4,500 ib tonne, S690Q yog hais txog CNY 6,800 ib tonne), cov khoom siv tus nqi ntawm ib lub thawv girder yog: CNY 83,700 rau Q345B scheme thiab CNY 88,400 rau CNY 7 scheme nkaus xwb.

Kev Thauj Mus Los thiab Hoisting Tus Nqi: Tom qab txo qhov hnyav, lub tsheb thauj mus los rau ib lub thawv girder tau hloov los ntawm ib qho hnyav - lub luag haujlwm trailer (load peev 20 tonnes) mus rau ib qho trailer (load peev 15 tonnes), thiab tus nqi thauj mus los tau txo los ntawm CNY 1,200 ib ntu rau CNY 800 ib ntu; cov khoom siv hoisting tau hloov los ntawm 500-tuj crane mus rau 300-tuj crane, thiab tus nqi hoisting raug txo los ntawm CNY 8,000 ib ntu rau CNY 5,000 ib ntu. Tag nrho cov tsheb thauj mus los + tus nqi hoisting rau ib lub thawv girder tau txais kev cawmdim los ntawm CNY 3,400, offsetting qhov nce ntawm cov khoom siv, uas ua rau ib tug net txuag ntawm CNY 2,930 ib seem.
