Tam qhob beams: Hom thiab nta

Nws yog ib qho nyuaj rau xav txog tej yam ib tug niaj hnub tsev hnub no, uas tsis thov ib tug nqaj ua kev reinforced. Cov ntsiab yog qhov tseem ceeb nyob rau hauv kev tsim kho ntawm tag nrho cov hom ntawm cov lug thiab ceilings. Tam qhob beams yog siv nyob rau hauv lub lwm ntawm lub runways ntawm tshav dav hlau, ib ntus nkag txoj kev, qhov kev siv ntawm cov txuas hniav. Siv rau qhov siv thiab ua cov khoom yog check thiab resistant mus rau ntau yam hom impacts, li ntawd, hais tias xws li overlap yog tsis tshua muaj ruaj. Ib tug txheej txheem ntawm installation yog ceev txaus.

Tam qhob beams: ntau lawm

Prefabricated reinforced beams (GOST 20372-90, 24893.2-81, 24893.1-81) yog ua tau tsuas yog nyob rau hauv cov nroj tsuag thiab cov khoom - yog manufactured los ntawm pouring qhob mortar mus rau hauv lub preformed reinforcing lug, rods uas yog nruj nrog jacks. Sealing khoom nqa los ntawm lub co technology. Cov tshuaj solidifies nyob rau hauv daim ntawv ntawm kwv yees li 12 teev, whereupon cov khoom noj tawm rau hauv lub qhib cua rau kho lawv lub zog.

Thaum raug yog tsim nyog los soj ntsuam ib qho tseem ceeb parameter: lub pob zeb sib tov yuav tsum muab faib raws li uniformly li sai tau thoob plaws hauv lub qhov chaw zoo. Yuav kom tsim cov khoom siv ua vaj tse qib 200 thiab saum toj no. Npaj tam qhob beams muaj ib tug tsim load ntawm 450 kilogram / quab yuam ib square meter.

Hom ntawm bar Siv

Tag nrho cov tam sim no cov khoom raug muab faib ua peb pawg nyob rau cov qauv ntawm cov ntau lawm:

1. teams - yog manufactured nyob rau hauv lub Hoobkas;
2. monolithic - nchuav ntawm qhov kev siv qhov chaw;
3. precast-monolithic.

Cov feem nrov hom kab teeb yog suav tias yog ib qho los ua ke tsim, uas yog ua los ntawm hnyav qhob nyiaj muas. Nws yog txaus muaj zog, muaj ib tug muaj kev kawm siab, yog tam sim ntawd npaj rau lub rooj sib txoos.

Pem teb beams reinforced GOST 28737-90: lub hom siv

Nyob rau hauv qhov kev siv sector muaj yog ib tug faib ntaub ntawv beams los ntawm hom:

• Gable yog pa thiab grating, denoted txiav npluav;
• ntshiv-pob zeb ua beams luv luv hu ua BSO;
• truss nrog thaum uas tig mus chords - BSS thiab thiaj li nyob.

foundation beams

Rau lawv cov khoom, siv tshwj xeeb qhob qib uas txawv kev kawm ntawv siab, tab sis, theej lub zog ntseeg. Xws li ib tug nqaj ua kev reinforced yog dav siv nyob rau hauv loj-scale muaj kev tsim kho. Zoo tagnrho rau tej qhov chaw uas muaj cov heev tshee thiab muaj zog seismicity. Qhov no hom ntawm beam yog tsim los rau hnyav heev loads. Lawv installation kom zoo waterproofing, kiag li xa kev sib cuag nrog cov av phaj. Tej zaum lawv yog siv rau lub installation ntawm qhov rais thiab qhov rooj qhib.

Truss qhob beams

Qhov no pab pawg neeg theem ua ke ob peb ntau yam ntawm pob zeb beams:

• tso;
• Gable.

Nyob rau Upper siv configurations, lawv tej zaum yuav yog polygonal, thiab curvilinear. Qhov no hom yog dav siv nyob rau hauv vov tsev, nyob rau hauv particular, siv rau kev tsim kho ntawm ib tug txhim khu kev qha thiab muaj zog cov plag tsev, uas yuav tsum mas siab loads. Piv txwv li, qhov chaw uas muaj crane cov khoom. Nws yuav ua tau ib tug enterprise nrog ib tug muaj specialization, loj warehouses, tsiaj nyeg chaw, nyob qhov twg rub unloading / loading ntawm hnyav khoom, raws li zoo li lwm yam uas zoo sib xws tej hauj lwm. Truss qhob beams nruab nrog tshwj xeeb kev tsheb nqaj hlau fasteners, uas yog siv los txhim kho cov khoom.

lub beams

BP - hauv daim ntawv ntawm cov nqaj, feem ntau siv nyob rau hauv kev tsim kho. Cov feem nrov ntawm lawv yog cov tshwj xeeb qauv uas yog nruab nrog lub txee nyob saum toj no los yog hauv qab no. Cov yooj yim yam ntxwv caij ntawm T-zoo li tus ntoo khaub lig seem yog cia li xws li ib tug beam. Yuav tsum vov tam (qhov ntev yuav mus txog 24 m) yog sau los ntawm tus spans, qhov ntev uas yuav tsum tsis pub tshaj 12 meters. Nyob rau hauv qhov kev siv kev lag luam no tsiaj yog suav tias yog lub feem ntau robust thiab haib. Muaj kuj yog ib tug PSU nrog ib tug L-zoo li tus ntoo khaub lig-section, lawv yog tsim los txhawb cov facades.

Nws yuav tsum tau muab sau tseg tias kev siv ntawm kev reinforced - nws yog ib tug ntawm cov feem ntau pheej sectors, uas raug thawb rau ib sab rau kev siv ntawm loj designs ntawm khoom hlau thiab archaic tsob ntoo. Tsaug rau qhov kev pom piv ntawm cov nqi thiab zoo npaum li, ua kev reinforced beam yuav rightly yuav hu ua ib qho zoo tagnrho cov ntaub ntawv uas rau niaj hnub kev lag luam.
