Yog, h {- nqaj ntau qhov sib txawv ntawm cov qauv hauv cheeb tsam. Piv txwv li, European En 10025 tus qauv muaj kab teeb ci li hea 100 (100 × 100 × 8), thaum Amelikas Aisc txheej siv W14 × 178 × 98). Suav GB / T 11263 qhia txog Hm 194 × 150 × 9. Cov kev hloov pauv no suav nrog qhov sib txawv hauv qhov siab, dav, Flange tuab, thiab web tuab. Cov kws tsim txuj ci yuav tsum xaiv kab teeb sib txuam nrog txoj haujlwm tus qauv hauv zos kom ua raws li kev ua lub tsev thiab kev nyab xeeb.
Dab tsi yog qhov siab tshaj plaws Flangness ntawm hom h - Beams?
Hom H - kab teeb muaj qhov siab tshaj plaws uas muaj 50 hli. Piv txwv li, qhov loj loj European Heb 1000 lub nqaj muaj Flangnesses ntawm 49mm, thiab Asmeskas Breat muaj Flanging Thickness ntawm 48.3mm. Thicker Flanges (30 {- 50mm) yog pom nyob rau hauv hnyav {{}} Lub zog cog cov qauv, lossis muaj cov tuam tsev nrog cov khoom siv siab. Flange thickness ncaj qha cuam tshuam cov nqaj nqaj muaj lub zog; Thicker flanges txhim kho rau cov rog puas.
Yog vim li cas h - Beams muaj zog dua li i ... 1}} Beams ntawm qhov loj me?
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.
