H - Beams muaj zog dua i,, {ci ntawm qhov loj me me vim lawv cov khaub ncaws flange tuab thiab dav dav web. H - Beams muaj flanges nrog tuab tuab (tsis muaj tapering), faib cov plaub hau ncaj ncees hla cov flange. Lawv lub vev xaib kuj tseem dav, txhim kho lub zog. Hauv kev sib piv, Kuv - cov kab teeb (thicker ntawm lub vev xaib, thicker ntawm cov npoo), uas txo lawv cov kabmob muaj peev xwm. Piv txwv li, H200 × 100 Beam tuaj yeem nqa ntau cov load ntau dua li i200 × 100 ci ntsa iab zoo tagnrho rau cov qauv hnyav.
Yuav ua li cas h - Beams txuag cov khoom siv piv rau cov hlau nplaum steel?
H - Beams txuag cov ntaub ntawv los ntawm kev siv hollow, optimized hla {1} {1} {seem. Cov hlau ntim cov hlau muaj cov khaub ncaws zoo sib xws, yog li ntawm cov khoom siv yog tsis muaj qab hau (tsuas yog sab nraud feem puas yog khoov). H - kab teeb muaj lub vev xaib (ntsug) thiab kab rov tav) uas muaj zog (kab rov tav (kab rov tav tawm ntawm kev khoov, thiab lub vev xaib tiv thaiv. Piv txwv li, 200mm × 100 hli h {8} Beam / m ntawm steel, thaum ua ib qho khoom siv 200 hli × 1007kg / m. Cov qauv tsim no txiav cov khoom siv los ntawm 70-80%, cov nqi qis dua thiab txo tus qauv tus qauv hnyav.
Dab tsi ua rau h - Beams yooj yim sib sau ua ke hauv kev tsim kho?
H - Beams yog yooj yim sib dhos vim lawv cov tiaj tiaj, flanges ncaj thiab muaj qhov ntau thiab tsawg. Lawv cov flanges muab cov chaw loj, tiaj tiaj rau vuam lossis bolting mus rau lwm cov (piv txwv li, kab, lwm cov nqaj). Tsis zoo li cov hlau txawv txawv, h- Beams li sai {6} Cov neeg ua haujlwm tau sai sai (qib, clamps). Standardized sizes (per EN, AISC, etc.) mean pre-drilled holes (for bolts) match across beams, reducing on-site cutting. Qhov no yooj yim nrawm nrawm: Ib pab neeg tuaj yeem sib dhos rau h- nqaj} tsov ntxhuav.
Ua h {- cov kab teeb pom kev ua tau zoo rau torsional rog?
H - Beams muaj tergerate torsional (sib ntswg) tsis kam, zoo dua li kuv} Beams tab sis tsawg dua li lub thawv kab teeb. Lawv tus ntoo khaub lig zoo ib yam-} flganges ntawm ob sab) pab faib cov forces tusyees. Txawm li cas los xij, lawv qhib ntoo khaub lig - ntu (hollow web) txhais tau tias lawv tuaj yeem sib ntswg nyob rau hauv lub siab siab. Txhawm rau txhim kho torsional kuj, engineers feem ntau khub h} Cov kab hlau nplaum nrog lub torsion uas yog cov thav duab qis (piv txwv li cov thav duab, tsis yog nkoj hulls). Rau siab- torsion cov ntawv thov (piv txwv li, txuas hniav nrog hnyav rau sab tom qab loads), h} Beams yuav pab txhawb nrog cov phiaj ntxiv.
Yog vim li cas h - Beams haum rau ntev-} span cov qauv?
H - Beams Excel nyob rau hauv ntev- lub zog) Vim tias lawv muaj zog} {5} Qhov hnyav} qhov hnyav. Lawv dav dav thiab tuab web tso cai rau lawv mus rau ncua 10-30 meters yam tsis muaj kev tiv thaiv ntau dhau (khoov). Piv txwv li, 30m ntev nyob rau hauv ib lub tsev rau khoom siv tau siv H600 × 200 kab teeb, uas hnyav tsawg dua li cov steel steel tab sis tseem txhawb nqa lub ru tsev. Lawv lub teeb yuag txo cov thauj khoom ntawm cov kab ntawv thiab cov hauv paus, txiav cov nqi tshaj plaws. Tsis tas li ntawd, lawv cov rigidity txwv tsis pub dhau lub sijhawm dhau los, ua kom tus qauv tseem nyab xeeb thiab ruaj khov rau xyoo lawm.
