Nqaj double-tee: Qhov ntev. I-beam ntoo beam

Cov kab teeb siv nyob rau hauv kev tsim kho thaum lub tsev ru tsev, ceilings, plag tsev , thiab thiaj li nyob. D. Muaj ib tug ntau yam ntawm hom. Qhov tseem check hom yog kuv nqaj - ib tug tshwj xeeb tsim, nyob rau hauv tus ntoo khaub lig-seem uas repeats cov tsab ntawv "H". Qhov no tsev cov ntaub ntawv uas ua los ntawm ib tug hlau yuav los yog ntoo.

Steel I-beam

Nrog rau kev tso tawm ntawm no tsiaj yuav siv tau raws li dov carbon thiab tsawg hlau steel. Thov I-beams nyob rau hauv ntau qhov chaw ntawm pej xeem thiab cov muaj kev tsim kho. Feem ntau qhov no cov ntaub ntawv uas yog siv, Yog hais tias tsim nyog los muab ib tug ncej qauv los yog nws qhov chaw nce lub zog thiab rigidity. Muaj I-beams thiab welded manufactured los ntawm kub dov. Qhov kawg yog cov feem ntau nrov.

ASIC zog nyob rau hauv no cov ntaub ntawv uas muaj lwm kom zoo dua. Kuv- joists yog heev resistant rau kub hloov mus hloov los. Yog li ntawd, lawv yog feem ntau kuj siv nyob rau hauv kev tsim kho ntawm unheated chav.

Scope

Yeej, Nqaj double-tee, qhov luaj li cas ntawm cov uas tej zaum yuav sib txawv, siv nyob rau hauv kev tsim kho ntawm cov plag tsev nyob rau hauv kev tsim kho ntawm muaj thiab civil vaj tse. Nws kuj yog ib tug zoo ntawm koj qev los yog feem ntau siv thaum lub tsev choj thiab rau qhov cuab lub zog ntawm mines. Heev lug siv no leej niam nyob rau hauv lub tsheb tsev thiab tsheb industries.

Cov ntaub ntawv I-beams

Qhov no hom yog txwv kom muab zais dov tsis tau tsuas yog los ntawm cov qauv ntawm cov siv thiab ua, tab sis kuj nyob rau hauv lub meej ntawm kev tsim kho. Lub beam yuav muaj ib tug muab ob npaug rau-tee li thaum uas tig mus rhawv, thiab pov tseg ntawm lub kaum sab xis. Nyob rau hauv lub caij nyoog kawg no cov ntaub ntawv, cov koj qev los yog muab faib mus rau hauv:

• tshwj xeeb,
• dab tsi (nrog rhawv nqes hav los ntawm 6 mus rau 12%).

Tshwj xeeb I-beam (GOST 19425-74), nyob rau hauv lem, yog txwv kom muab zais rau hauv:

• npaj mus pab rau tus ncej (cim nrog tsab ntawv "C");
• siv nyob rau hauv qhov siv thiab ua cuav paths ( "M").

Kab teeb nrog thaum uas tig mus flanges (GOST 26020-83) muab faib ua:

• dab tsi (cim "B"),
• wide- (W),
• pej thuam (K).

Tsis tas li ntawd hlau I-beams tej zaum yuav txawv raws li tus thickness ntawm txee thiab phab ntsa.

Nqaj double-tee: Qhov ntev

Lub qhov siab ntawm no tus ntoo khaub lig-sectional saib kuav los tiag kuj muaj ntau. Qhov no xam yog tom qhua thiab txiav txim seb nws ua tau rau hauv lub beam tooj. Yog li, ib tug qhov siab ntawm 140 hli raws li cov ntaub ntawv uas yuav tsum tau cim 14C nyob rau hauv 360 mm - 36M, thiab lwm yam ...

Cov qhov ntev ntawm kev siv cov ntsiab ntawm cov hom ntxuag yog txiav txim los ntawm tshwj xeeb ntxhuav. Ntawm no, nws tseem tau mus paub tus luj ntawm lub I-beam.

lus dab neeg:

• b - lub dav ntawm lub txee,
• t - nws nruab nrab thickness,
• S - phab ntsa thickness,
• h - qhov siab ntawm ib tug I-beam,
• R - Internal voos kheej-kheej ntawm curvature,
• R- voos kheej-kheej txee.

Beams ntoo kab teeb

Qhov no zoo ntawm lub tsev cov ntaub ntawv uas, ib yam li hlau, yog yus muaj los ntawm siab zog thiab zoo heev zoo. Jumper H-beam ntoo feem ntau ua los ntawm plywood los yog OSB, txee - los ntawm planed lumber. Muaj kuj yog ib tug zoo ntawm plywood. Nyob rau hauv cov ntaub ntawv no, tus tav ua veneer laminate. Glued I-beams yog tsawg raug rau lwj. Nyob rau hauv tas li ntawd, lawv muaj ntau hluav taws resistant.

Kev cob cog rua rau txhua lwm yam I-beams ua los ntawm cov ntoo nrog tshwj xeeb nkhaus. Cov yav tas muaj xws li thaum uas tig mus hlau paib thiab txhav tas ntaus ntawv. Connectors yuav muaj ntau ntau thiab tsawg. Yog hais tias tsim nyog, yuav tsum yooj yim rau hais txog kev xaiv, hom phiaj haum rau lub qhov siab ntawm lub pob zeb ua kab teeb.

Scope ntawm kev siv

Siv ob npaug rau-tee ntoo beam mas nyob rau hauv kev tsim kho ntawm vaj tse ntawm ncej-ntaub thaiv npog. Tsis tas li ntawd, qhov no cov ntaub ntawv uas yog feem ntau ua ib tug pab txhawb nqa cib slabs, thaiv thiab khoom qhob tsev. Cov plag tsev yog pw rau ntawm joists ntawm no tsiaj yog yus muaj los ntawm siab rigidity, tsis creak thiab yeej tsis khoov.

Nrog kev tsim kho ntawm lub ru tsev ntawm loj vaj tse ua los ntawm I-beams thiab rafters yuav ua nees. Qhov no kuj cov khoom tshiab yeej muaj peev xwm hloov txwm siv rau qhov no kawg, ntoo kab teeb, hlau pwm, qhob slabs. Feem ntau, cov chaw tsim tshuaj paus muab ib tug guarantee rau I-beams rau tag nrho cov kab ntawm cov qauv ntawm cov kev pab cuam.

khoom pab cuam

Qhov zoo ntawm cov double-tee ntoo beam yog teem. Qhov no cov ntaub ntawv uas yog distinguished los ntawm tej nta li:

• Zog. I-beams yuav ntsia tau rau hauv ntev heev qhib.
• Seem stability. Cov beams tsis khoov thiab yog tsis raug shrinkage thiab deformation.
• Tejzaum ntawm installation. Kov lub tuam tsev no cov ntaub ntawv uas yuav ua tau pa ntoo cuab yeej.
• Versatility. Siv ib tug nqaj nrog ob tug rhawv tej zaum yuav nyob rau hauv ib tug hauv pem teb siv, plag tsev, cov phab ntsa, ru tsev thiab cov zoo li. D.
• Lightness. Nyhav I-beam ua los ntawm cov ntoo yog tsuas 3-4 kg. Yuav kom nce xws li ib lub caij, piv txwv li, lub-ru tsev tsis yuav tsum tau tshwj xeeb cov khoom. Ua nws yuav tsuas yog ob tug neeg.
• Tsis tshua muaj nqi.

Qhov ntev khoom

Nrog kev tsim kho ntawm vaj tse yuav siv tau los ntawm txawv nqaj ob npaug rau-tee. Nws loj, me, feem ntau siv nyob rau hauv kev tsim kho, yog:

• ntev - 241, 302, 356, 406 hli,
• txee dav - 64 hli,
• flange thickness - 38 hli.

Vim qhov no cov ntaub ntawv uas yog feem ntau siv nyob rau hauv lub rooj sib txoos ntawm ceilings nyob rau hauv dav heev qhib, nws yog tej zaum tsim nyog los tsim li. SNIP yog tau tso cai. Nyob rau hauv cov pob qij txha ntawm ob kab teeb nyob rau tib lub sij hawm zapilivaem locks. Ntxiv kho yog ua li cas rau cov bolts.

Nyob rau hauv dav dav, lub tsev ntaub yog check heev thiab siab zoo - ntoo I-kab teeb. GOST, raws li nyob rau hauv cov ntaub ntawv ntawm cov hlau hom, regulates tus piv ntawm lub qhov siab thiab luaj li cas ntawm cov ntsiab ntawm cov hom kev txhawb zog. Saib lawv yuav tsum tau nyob rau hauv tshwj xeeb ntxhuav.

Yuav ua li cas ua kuv-beam nyob rau hauv lub tsev

Yog hais tias qhov kev kawm, xws li ib tug kev tsim kho yuav tau muab manufactured thiab tom tsev. Qhov no yuav tsum muaj ob leeg bar seem ntawm tsawg kawg yog 35h25 hli. Jumper ua los ntawm plywood los yog OSB. Koj yuav tsum tau ib tug hluav taws xob los yog ib tug chainsaw. Ua hauj lwm yog nqa tawm nyob rau hauv lub nram qab no:

• Ua ntej, nyob rau hauv lub tuav raws lawv tag nrho ntev sawed zawj tob ntawm 10% ntawm lub qhov siab ntawm lub lintel.
• Lawv ces muab txiav kom tus xav ntev, thiab sanded.
• Tom qab ntawd, hauv qab ntawm txhua furrow daim ntawv thov ntawm cov nplaum.
• Khiav compound beams pairwise siv plywood los yog OSB.

Thaum lub theem kawg hauv lub tiav lawm beam rau muab nyob rau hauv xovxwm. Kom nws kuj tau nws tus kheej. Rau lub hom phiaj no, channel tuav. Lawv muab tso rau hauv rhawv thiab rub ua ke uas siv phom los yog koj cov menyuam.

Yog li ua lub tsev cov ntaub ntawv uas yog cheaper npaum li tshaj lub purchase Nqaj double-tee. Tus nqi ntawm cov caij nyoog kawg no tej zaum yuav ywj faj ywj fwm nyob ib ncig ntawm 200-250 rubles. Ntawv sau los ntawm koj tus kheej nws yuav yuav tsim nyog nws nyob rau hauv lub 1.5-3 lub sij hawm pheej yig dua.

Aluminium I-beams

Lub tsev no hom ntawm cov ntaub ntawv uas kuj muaj zoo lub dag lub zog. Muab ob npaug rau tee beam yog ua los ntawm txhuas hlau feem ntau AD31. Qhov no hom yog feem ntau siv nyob rau hauv kev tsim kho ntawm lub tsev nyob. Tsis tas li ntawd beams no yog ua los ntawm txhuas hlau 1915. Qhov no hom muaj siab muaj zog. Aluminium beams muaj muaj zog thiab sib zog tshaj steel ntoo.

cov ntaub ntawv uas ntau yam

Muaj txhuas I-beams:

• tawv,
• annealed,
• uas muaj hnub nyoog.

Cov txheej cov ntaub ntawv uas tej zaum yuav pleev xim rau, Anodized, hmoov, electrophoretic, ib ob-txheej complex. Raws li cov tej yam kev mob ntawm kev siv txhuas I-beams, raws li zoo raws li steel, yuav tsum tau muab faib mus rau hauv wide-, kem thiab ib txwm. Labeling nyob rau hauv cov ntaub ntawv no siv tau tib yam.

Qhov ntev

Aluminium double-tee beam ntau thiab tsawg pab kuj yuav sib txawv. Qhov ntev nyob rau hauv cov ntaub ntawv no yog txiav txim los ntawm GOST. Kom ua thiab labeling. Lub qhov siab ntawm cov txhuas beam yuav sib txawv ntawm 10 mus rau 100 cm nyob rau hauv thawj cov ntaub ntawv raws li GOST tso kom muaj kab muaj kev yuav muaj ib tug dav ntawm 55 hli thickness -. 4.5 hli. Txiav txim seb tus piv ntawm cov tsis nyob rau hauv txhua rooj plaub yuav tsum yog tus ntxhuav.
