I. Cov ntaub ntawv dav dav

Txoj Haujlwm Lub Npe: Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Siv Hluav Taws Xob rau Tag Nrho Cov Nqa ntawm Loj -Span, Heavy-Load Steel Truss Walkways

II. Qhov project Background

Qhov project hauv nqe lus nug yog 'Anhui University Jianghuai College New Campus Project - Lot 2'. Cov kev taug kev steel muaj qhov loj (qhov siab tshaj plaws ntawm 64.8 m) thiab qhov hnyav hnyav (qhov hnyav tshaj plaws ntawm 980 t). Cov teeb meem tseem ceeb uas yuav tsum tau saib xyuas hauv txoj haujlwm no suav nrog kev ua kom muaj kev nyab xeeb thaum lub sij hawm kev teeb tsa ntawm txoj kev taug kev tag nrho cov lifting ncej, tswj synchronization thaum lub sij hawm nqa tag nrho (dhau plaub lub ntsiab lus nqa), ua kom muaj kev ruaj ntseg thaum lub sij hawm corbel installation, thiab tiv thaiv kev poob ntawm qhov siab thaum ua hauj lwm ntawm qhov siab. Txhawm rau daws cov teeb meem tseem ceeb no, peb tau ua kom zoo dua cov txheej txheem tsim rau hauv av sib dhos jigs rau loj- cheeb tsam, hnyav- load trusses; tsim ib txoj kev optimization rau lub pre-arching ntawm loj-span steel trusses; tsim kev tswj xyuas zoo rau vuam siab- lub zog tuab steel phaj hauv qhov chaw; tsim precision tswj optimization tshuab rau hydraulic lifting loj-span, hnyav{12}}load spatial steel trusses; thiab optimized cov qauv tsim rau lifting thav duab thiab sab sauv / qis lifting ntsiab lus.
 

III. Kev ua tau zoo tshiab

(1) Ua ntej, txhawm rau ua kom qhov tseeb ntawm cov khoom siv steel hlau, cov txheej txheem vuam rau Q420B ultra-tuab siab- lub zog steel daim hlau thiab lub pob tw- vuam txoj kev rau ntau - flange steel kab teeb nrog misalignment tau tsim, zoo daws teeb meem ntawm kev sib koom ua ke ntawm feas. suav nrog ultra- tuab siab - lub zog steel phaj.

(2) Thib ob, txhawm rau xyuas kom meej qhov chaw ntawm cov hlau corbels thiab lawv cov kev teeb tsa raug rau hauv ua ntej - nrum sockets, peb tsim ib lub jig rau lub synchronized lifting thiab meej kev sib txuas ntawm ntev -span steel walkways thiab corbel beams, nrog rau jig rau tag nrho lifting ntawm ntev {{3}. Cov kev tsim kho tshiab no daws tau cov teeb meem ntawm kev tso cov hlau corbels thiab txhim kho lawv kom raug rau hauv ua ntej - nrum sockets hauv qhov chaw kaw.

(3) Thaum kawg, hais txog qhov tsis sib xws ntawm lub xeev kev ntxhov siab ntawm txoj kev nqa cov hlau thaum lub sij hawm nqa thiab nws cov qauv tsim, kev simulation thiab kev txheeb xyuas kev suav tau ua rau tag nrho cov txheej txheem ntawm txoj kev nqa tag nrho thiab kev tsim kho ntawm cov lifting nodes, yog li ua kom muaj kev ruaj ntseg ntawm cov hlau taug kev thaum lub sij hawm nqa thiab qhov siab tag nrho.

IV. Kev siv thiab kev siv

Cov kev tshawb fawb tshawb pom ntawm "Integrated Lifting Construction Technology for Long-Span, Heavy-Load Steel Truss Walkways" tau ua tiav rau cov qauv steel ua haujlwm ntawm Anhui University Jianghuai College New Campus - Tshooj 2 qhov project, ua los ntawm peb lub tuam txhab. Txoj kev tsim kho no muaj qhov zoo xws li kev tsim kho sai, kev ua tau zoo thiab tus nqi- ua tau zoo. Nws tau daws cov teeb meem kev tsim kho tau zoo nrog rau kev ua tiav qeeb, teeb meem hauv kev tswj hwm qhov tseeb thiab ntau qhov sib tshooj ntawm kev tsim kho. Nws tuav cov lus qhia dav dav rau cov haujlwm tsim kho zoo sib xws, tau txais kev qhuas zoo los ntawm cov neeg siv khoom, thiab muaj kev cia siab ntau rau kev txhawb nqa thiab kev thov.
