Section Steel Support Scheme

Cov txheej txheem steel kev txhawb nqa, uas yog, tsuas yog kev txhawb nqa seem steel lossis cantilever seem steel yog tsim nyob rau hauv qis txheej ntawm lub siab txhawb pwm cheeb tsam, thiab tom qab ntawd steel yeeb nkab txhawb nqa ncej yog tsim los tsim cov txheej txheem ntawm sealing phaj lossis cantilever phaj. . Cov tswv yim no yog theoretically ua tau, tab sis nyob rau hauv qhov project no, qhov qhib ncua yog loj heev, qhov siab yog heev siab, lub cantilever ntev ntev thiab muaj hnyav load xws li girder. Txhawm rau kom muaj kev nyab xeeb ntawm kev tsim kho, nws raug suav tias cov hlau seem yuav tsum yog tsawg kawg 40 # I steel lossis lwm qhov sib npaug ntawm lub zog steel, thiab qhov sib txawv ntawm qhov sib txawv me me. Hom loj loj seem steel yog tsawg nyob rau hauv kev ua lag luam. Nws yuav tsum tau kho, thiab qhov zoo ntawm txhua 'meter' ntev yog loj, muaj ntau yam shortcomings xws li nyuaj rau dismantling, muaj kev nyab xeeb txaus ntshai, nyuaj nyob rau hauv turnover thiab kev lag luam tsawg, yog li nws tsis haum rau kev siv.
