Peb kab bracing yog cov txheej txheem thib ob uas siv los txhim kho kev txhawb nqa ntsug thiab xa ncaj qha mus rau sab nraud (xws li cua, seismic, thiab crane txav) mus rau lub hauv paus. Nws tiv thaiv thav duab deformation, txo tawm - ntawm - dav hlau dabtsi yog khoov, thiab txhim kho cov axial load-cov kabmob muaj peev xwm ntawm txhua kab.
Hom Peb Steel Kem Bracing
Raws li tus kws tshaj lij steel qauv tsim, peb muab ntau yam ntawm ntsug bracing systems raws li thoob ntiaj teb seismic codes xws li GB, AISC/ASTM, thiab EN.Peb txhawb 100% customization raws li cov neeg siv 'kev kos duab tshwj xeeb thiab qhov yuav tsum tau ua, muab ntau yam xws li X-bracing, Inverted V-bracing, V{4}
X-Bracing (Cross Bracing)

Qhov zoo ntawm Steel Kem Bracing
Xyuas kom tag nrho Spatial Stability
Kem bracing ua hauj lwm ua ke nrog transverse thav duab los tsim lub longitudinal thav duab system, ntseeg tau hloov longitudinal kab rov tav rog (xws li, gable cua loads thiab crane longitudinal braking rog) rau lub hauv paus. Txhim kho kem bracing kom zoo tuaj yeem txwv cov kab saum toj kawg nkaus rau hauv qhov txwv tsim ntawm 1/1000 txog 1/500, tiv thaiv kev ua haujlwm zoo.
Ua kom ntseeg tau Longitudinal Lateral Stiffness thiab Stability
Kem bracing ua hauj lwm ua ke nrog thav duab kab los tsim lub longitudinal thav duab system, nqa thiab xa mus rau longitudinal kab rov tav rog. Nyob rau hauv seismic lossis siab cua ua haujlwm, kab kab muaj kev cuam tshuam rau sab buckling; Kev npaj bracing kom zoo tuaj yeem txo qhov tawm - ntawm - dav hlau ntev ntawm kab, yog li txuag kwv yees li 15% mus rau 30% hauv steel kem tonnage.
Hloov Gable Cua Loads
Cua loads ua rau lub tsev gable yog kis los ntawm lub ru tsev transverse bracing mus rau kem bracing, thiab ces los ntawm bracing mus rau lub hauv paus. Feem ntau, kem bracing yuav tsum nqa 30% mus rau 50% ntawm tag nrho cov kab rov tav cua load kis los ntawm gable.
Nqa Crane Longitudinal Braking Forces
Hauv cov nroj tsuag muaj kev lag luam, qhov ntev ntawm txoj kab rov tav feem ntau yog tsim thaum lub crane trolley mus los yog tus choj nres. Cov rog no tau xa ncaj qha los ntawm crane girder system mus rau kem bracing, uas tuaj yeem nqus tau thiab xa tawm kwv yees li 40% mus rau 60% ntawm cov kev cuam tshuam zoo li no, tiv thaiv kev cuam tshuam ntev ntawm lub tsev.
Kev siv ntawm Steel Kem Bracing
Cov nroj tsuag muaj:Hauv cov chaw tsim khoom hnyav, kem bracing feem ntau nqa crane longitudinal braking rog, cua loads, thiab seismic ua. Nws tau muab faib ua kem sab sauv thiab sab qis bracing kom ntseeg tau tias lub longitudinal txhav thiab stability ntawm lub tsev.
Ntau-Zaj dab neeg thiab siab-Rise Steel Structures:Raws li qhov tseem ceeb ntawm lub zog sab nraud- tawm tsam qhov system, nws feem ntau siv nyob ib puag ncig cov tub ntxhais kawm ib puag ncig lossis nruab nrab ntawm cov thav duab, tiv thaiv kab rov tav shear quab yuam vim cua thiab seismic.
Erection thiab Installation Stage:Muab bracing ib ntus rau cov txheej txheem thav duab los tiv thaiv kev hloov pauv lossis hloov pauv thaum lub sij hawm hoisting thiab lub ntsiab qauv sib dhos.
Kev sib xyaw ua ke ntawm Peb Cov Kab Hlau Hlau Bracing
Peb cov qauv steel kem bracing system feem ntau muaj ob lub hauv paus khoom siv: qhov hloov tau yooj yim khi pas nrig system (round steel tuav nrog turnbuckles) thiab cov tswvcuab nruj (cov qauv steel ntu / steel hlab). Txhua yam khoom siv sib txawv raws li qhov sib txawv ntawm qhov kev xav tau ntawm engineering thiab kev siv scenarios:
Round Steel Kem Bracing System (nrog Turnbuckle)
Lub teeb yuag, yooj yim rau nruab, thiab pom qhov muag qhib, nws feem ntau tso siab rau cov khoom siv tensioning kom tswj lub xeev tensioned.
Precisely haum rau lub teeb portal thav duab los yog tsawg-load vaj tse.
Qauv Steel Seem los yog Hlau Tube Kab Bracing System (Angle Steel / H-Section Steel / Square lossis Round Tube)
Siab tawv, siab load-cov kabmob muaj peev xwm, thiab cov khoom thauj tsis sib xws; muaj peev xwm ib txhij nqa compressive thiab tensile stresses nyob rau hauv tus ntoo khaub lig-section.
Dav siv nyob rau hauv siab -nce vaj tse, hnyav ntau- zaj dab neeg muaj cov nroj tsuag, los yog thauj khoom- cov kabmob uas muaj kev tsim seismic siab.
Peb tuaj yeem muab 100% kev daws teeb meem rau kev lag luam zoo tshaj plaws thiab ua haujlwm zoo ntawm cov kab ke sib txuas ua ke thiab cov ntsiab lus sib koom ua ke raws li koj qhov project qhov siab qhov tseeb, qhov xav tau nruj, kev yooj yim fabrication, thiab qhov chaw teeb tsa.
Daim ntawv qhia qhov chaw rau Steel Kem Bracing
Rau cov tsev lag luam nruab nrog nyiaj siv ua haujlwm cranes, qhov sib nrug yuav nce mus txog 60 meters, nyob ntawm qhov siab ntawm lub tsev thiab npaj siv:
Thawj Bay Qhov Tseem Ceeb: Qhov twg tso cai, bracing yuav tsum tau muab tso rau hauv thawj qhov chaw ntawm ob qhov kawg ntawm cov qauv. Yog tias qhov chaw txwv tsis pub muaj qhov no, lub bay thib ob yuav raug siv, tab sis cov tswv cuab nruj ntxiv yuav tsum tau muab tso ua ke kom ntseeg tau tias kev thauj mus los tau zoo.
Tsis txhob ua haujlwm tsis sib haum xeeb: Txoj haujlwm ntawm cov qauv bracing yuav tsum tsis txhob cuam tshuam cov qhov rooj, qhov rais, lossis cov khoom siv tu. Hauv qhov chaw-cov chaw txwv, lwm yam kev teeb tsa yuav tsum tau txais yuav, xws li kev sib txuas ntawm lub qhov rooj lossis cov hlua khi- hom bracing.
Rau cov qauv teeb tsis muaj cranes, qhov kev ncua deb ntawm braced bays yuav tsum tsis txhob ntau tshaj 45 meters.
Rau cov tsev lag luam nruab nrog nyiaj siv ua haujlwm cranes, qhov sib nrug yuav nce mus txog 60 meters, nyob ntawm qhov siab ntawm lub tsev thiab npaj siv.

FAQ:
Yog vim li cas kab bracing tseem ceeb?
Yog tsis muaj kev sib khi zoo, cov kab ntsug tuaj yeem khoov lossis buckle hauv qab hnyav axial loads. Bracing txwv lub tsev sway, ua kom muaj kev nyab xeeb, thiab tswj kom muaj kev ncaj ncees ntawm tag nrho lub tsev lub hnab ntawv.
Dab tsi rog ua kab braces yeej tiv taus?
Bracing tuav lateral (sideways) loads -tsis yog lub ntsiab lub ntiajteb txawj nqus loads. Cov rog no los ntawm cov cua kub ceev (xws li ntawm 115 mph mus rau ntau dua 185 mph hauv qee thaj tsam hauv Teb Chaws Asmeskas), seismic kev ua si, thiab overhead crane txav.
Sab bracing feem ntau muab tso rau qhov twg?
Vertical bracing feem ntau yog ntsia rau hauv cov phiaj xwm phab ntsa bays, of elevator shafts, lossis central structural cores, thaum lub ru tsev thiab hauv pem teb bracing khi cov dav hlau kab rov tav ua ke kom faib cov quab yuam rau sab ntsug braced bays.
Yuav ua li cas yog tias kuv tsis khi kuv kab?
Yog tias tsis muaj kev sib khi kom zoo, cov kab hlau tuaj yeem buckle sideways nyob rau hauv axial qhov hnyav los yog sway ntau heev thaum raug rau ib puag ncig loads, uas yuav ua rau tag nrho cov qauv kev puas tsuaj.
Bracing cuam tshuam li cas rau lub tsev tsim thiab layout?
Bracing tuaj yeem txwv qhov qhib xws li lub qhov rooj lossis qhov rais hauv qee qhov chaw. Txawm li cas los xij, kev npaj tsim nyog tso cai rau kev sib koom ua ke tsis cuam tshuam rau kev ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv cov tsev lag luam.
Cov tshuab bracing puas tuaj yeem hloov kho lossis nthuav dav tom qab?
Yog lawm. Bracing systems tuaj yeem hloov kho lossis txuas ntxiv, tab sis cov kev hloov pauv yuav tsum tau tshuaj xyuas los ntawm tus kws tsim qauv tsim kom muaj kev ruaj ntseg thiab thauj khoom rov qab.
