Lub hauv caug Brace

Lub hauv caug brace yog ib qho kev txhawb nqa cov tswv cuab ntsia ntawm lub ces kaum kev sib txuas ntawm cov khoom siv hlau. Nws lub luag haujlwm tseem ceeb yog txhawm rau tiv thaiv cov buckling hauv cheeb tsam hauv thawj cov tswv cuab xws li kab teeb lossis kab thaum lawv nyob rau hauv compression.

Lub luag haujlwm tseem ceeb ntawm lub hauv caug brace yog tiv thaiv kev tsis ruaj khov. Thaum lub steel beam los yog kem bears ib tug load, nws flange los yog lub vev xaib tuaj yeem ua rau sab buckling. Lub hauv caug brace muab ib qho kev txwv sab nraud, zoo txwv qhov deformation. Nws kuj pab hloov lub zog thiab pab txhawb rau tag nrho kev ruaj ntseg ntawm cov qauv. Tsis tas li ntawd, siv lub hauv caug braces ua rau muaj kev sib txuas ntawm cov kab teeb, kab, thiab purlins, txhim kho lub cev tiv thaiv torsional.

Feem ntau thiab tus nqi- cov khoom siv tau zoo uas peb siv yog steel hlau (ob leeg sib npaug thiab tsis sib npaug), xaiv rau nws qhov zoo sib npaug ntawm kev ua tau zoo thiab yooj yim ntawm kev tsim. Peb kuj muab cov tubular steel lub hauv caug braces, feem ntau tshwj tseg rau cov ntawv thov uas muaj qhov zoo nkauj dua lossis cov khoom tshwj xeeb- cov kev cai bearing.

Peb faib lub hauv caug braces los ntawm lawv txoj kev sib txuas: bolted lossis welded. Hom bolted, fastened rau lub vev xaib ntawm cov tswv cuab tseem ceeb siv siab - lub zog bolts, yog peb txoj hauv kev zoo vim nws yooj yim installation thiab kho tau.

Peb lub hauv caug braces feem ntau yog siv nyob rau hauv cov tsev lag luam, ntau- zaj dab neeg steel qauv, thiab loj - ncua qhov chaw. Hauv cov chaw tsim khoom, piv txwv li, lawv tau nruab nruab nrab ntawm cov rafters thiab txhua kab ntawm lub portal thav duab, thiab nruab nrab ntawm lub ru tsev purlins thiab kab teeb, los pab tiv thaiv lub zog los ntawm kev ua haujlwm crane thiab cua.
