Lub portal rigid thav duab qauv yog ib lub teeb yuag spatial load-cov qauv bearing muaj li ntawm steel beams, steel kem, sib txuas connectors thiab bracing systems. Nws yog dav siv nyob rau hauv loj -span vaj tse xws li cov nroj tsuag muaj, warehouses thiab exhibition chaw. Tus tsim ntawm nws cov khoom ncaj qha txiav txim siab lub load-cov kabmob muaj peev xwm, kev ruaj khov thiab kev tsim kho yooj yim ntawm cov qauv. Cov haujlwm thiab cov yam ntxwv ntawm cov khoom tseem ceeb tau piav qhia hauv qab no.
Cov kab hlau thiab cov kab hlau hlau yog cov khoom thauj khoom tseem ceeb ntawm -cov kabmob ntawm cov ntaub ntawv tsis sib xws, feem ntau yog ua los ntawm welded H- zoo li cov hlau lossis kub- dov H- zoo li cov hlau. Tus ntoo khaub lig-sectional daim ntawv yuav tsum tau optimized raws li span, load thiab seismic yuav tsum.Feem ntau steel beams txais ib tug kuj sib txawv -section tsim: seem qhov siab yog nce nyob rau hauv cov kev txhawb nqa los tiv thaiv loj dabtsi yog khoov lub sij hawm, thaum seem yog txo nyob rau hauv txoj hauj lwm nrog me loads kom txuag tau cov ntaub ntawv steel. Cov kab hlau feem ntau siv qhov sib txawv -section lossis tas li-section tsim. Lawv cov kab hauv qab yog txuas nrog lub hauv paus ntawm cov pob qij txha, cov kabmob axial compression thiab kab rov tav shear rog.
Cov khoom sib koom ua ke yog tus yuam sij rau kev ua kom muaj kev ncaj ncees, suav nrog kab teeb -kem pob qij txha, kem- cov pob qij txha thiab kab teeb -beam splicing pob qij txha.Feem ntau beam -kem pob qij txha txais kev sib txuas nruj, uas tau paub los ntawm kev sib tw high{5} bolts; lub thickness ntawm qhov kawg daim hlau yuav tsum tau raws li qhov yuav tsum tau khoov kuj. Kem- cov pob qij txha hauv paus yog txuas nrog cov khoom siv thauj tog rau nkoj, thiab qhov kom muaj nuj nqis thiab kev teeb tsa ntawm lub thauj tog rau nkoj bolts yuav tsum tau txiav txim siab los ntawm kev txheeb xyuas qhov kev txhawb nqa.
Lub bracing system tau muab faib ua longitudinal bracings thiab transverse bracings, nws lub luag haujlwm tseem ceeb yog los tiv thaiv kab rov tav loads (cua loads thiab seismic loads) thiab tiv thaiv cov khoom tsis ruaj khov.
Longitudinal bracings yog teem nyob nruab nrab ntawm txhua kab raws qhov ntev kev taw qhia, thaum transverse bracings yog ntsia rau ntawm qhov kawg los yog nruab nrab bays ntawm lub thav duab nruj. Hla bracings thiab kab pheeb ces kaum bracings yog cov feem ntau saws cov ntaub ntawv, thiab cov ntaub ntawv feem ntau yog channel steel los yog lub kaum sab xis steel.
Tsis tas li ntawd, raws li cov khoom siv thib ob, lub ru tsev purlins thiab phab ntsa girts tsis tsuas yog dais cov khoom ntawm cov txheej txheem enclosure, tab sis kuj muab cov kev txwv rau sab nraud rau cov thav duab nruj, txhim kho tag nrho cov kev nruj ntawm cov qauv.
Hauv kev xaus, tag nrho cov khoom ntawm lub portal rigid thav duab ua haujlwm sib koom ua ke los nqa cov khoom thauj thiab ua lawv txoj haujlwm. Kev tsim cov khoom siv yuav tsum sib npaug ntawm cov neeg kho tshuab rationality thiab structural simplicity. Los ntawm kev siv cov qauv tsim thiab kev ua kom zoo ntawm kev sib koom ua ke, peb tuaj yeem txo cov nqi tsim kho thiab txo lub sijhawm tsim kho, qhia txog nws qhov zoo ntawm daim ntawv thov hauv loj -span hnyav steel qauv.
