Lub qhov ntev ntawm lub hlau bracket - Standard

Hlau kaum - ib tug khoom lug siv nyob rau hauv kev lag luam, nyob rau hauv vaj tse thiab lug, raws li zoo raws li nyob rau hauv lwm qhov chaw ntawm lub kev khwv nyiaj txiag. Qhov tshwj xeeb tsim cov ntawm no hom ntawm ntxuag muaj ib tug high nruj thiab yuav siv tau rau lub rooj sib txoos ntawm scaffolds nrog loj ntug ntawm kev ruaj ntseg. Nws yog ib lub ces kaum ntawm ib tug ntev steel khoom, nyob rau hauv tus ntoo khaub lig-section li tsab ntawv "G". Tsuas muaj ob ntawm nws lub ntsiab hom: sib npaug thiab tsis zoo tib. Nyob rau hauv thawj cov ntaub ntawv, lub dav ntawm cov khoom 'txee' yog tib yam nyob rau hauv lub thib ob - yog sib txawv. Qhov ntev ntawm cov hlau bracket, qhov nyhav thiab hom ntawm cov khoom siv rau kev tsim regulates GOST.

kev faib

Vaj huam sib luag thiab tsis zoo tib cov ces kaum tej zaum yuav:

• goryachekatnymi (manufactured raws li cov qauv tshuaj los ntawm GOST 8510-86 thiab GOST 8509-93);

• nkhaus (GOST 19771-93 thiab GOST 19772-93).

Tus thawj hom muaj siab muaj zog. Qhov no cheeb tsam yog kheev siv nyob rau hauv kev tsim kho ntawm steel lug raug siab loads. Nkhaus fab yog tus nrov tshaj plaws. Lawv siv qhov txhia chaw. Lawv yog ua los ntawm dabtsi yog khoov steel ib daim hlab rau lub bale tshwj xeeb cov khoom.

Tsis tas li ntawd, cov hlau cov khoom muaj txwv kom muab zais rau hauv:

• txheem;

• siab cov neeg.

Tus thawj zoo yog cim nrog tsab ntawv "B", qhov thib ob - "A".

Qhov ntev ntawm lub hlau lub

Raws li qhov tsis muaj cov khoom yuav txwv kom muab zais rau hauv ntsuas thiab unmeasured. Muaj kuj yog ib lub ces kaum ntawm ntau yam lengths thiab xwb. Seem khoom tej zaum yuav muaj ib tug ntev ntawm 6, 7, 9, 10, 11 los yog 12 m. Lawv nqi yog nyob rau hauv lub ceeb thawj (m. E. Tus neeg siv tsis them rau cov khoom tsev, thiab rau tag nrho cov kev yuav khoom los ntawm qhov ceeb thawj los, nyob rau hauv huab mob, rau lub yardage). Unmeasured cheeb tsam yuav muaj tej yam ntev. Nyob rau hauv cov ntaub ntawv no, qhov no daim duab mas nws txawv ntawm 4 mus rau 12 m. Nyob rau hauv Feem ntau, qhov no hom ntawm kev tsim kho cov ntaub ntawv yog tsis dhau lawm ntev, vim feem ntau mere trimming seem cov khoom.

Tej zaum, nyob rau hauv qhov siv thiab ua ntau hom ntas, load-tau cov kabmob lug, thiab hais txog. D. Yuav tsum tau hais tias qhov luaj li cas ntawm cov hlau nkhaus twb substandard. Nyob rau hauv cov ntaub ntawv no, tus neeg muaj tau mus yuam kom cov khoom ntev tshaj li 12 m.

kev ua yuam kev ntev

Ntawm lwm yam, regulates thiab GOST tolerances ces kaum rau hauv no parameter. Cov yav tas yuav tsum tsis txhob yuav ntau tshaj:

• 30 mm rau ib tug ntev ntawm 4 m ces kaum;

• 40 mm rau cov khoom rau 6 m;

• 70 mm rau lub kaum sab xis ntev ntawm 6 mus rau 12 m.

Yog koj thov, cov tsis yuav tsum tau hloov nyob rau hauv cov kev taw qhia ntawm ntau dua cov neeg (40 mm rau cov khoom uas 4-7 m ntxiv 5 hli ib 'meter' ntev ntawm ntau tshaj 7 m). GOSTS tswj tsis tau tsuas yog qhov luaj li cas ntawm ib tug hlau ces kaum sib npaug thiab tsis zoo tib, lawv cov luj thiab tolerances, tab sis kuj cov neeg kawm ntawv ntawm curvature. Tom qab tag nrho, high-quality khoom yuav tsum tau ncaj. Cov nqi siab tshaj plaws ntawm lub curvature ces kaum GOST yuav tsum tsis txhob ntau tshaj 0.4% ntawm qhov ntev. Thaum qhov kev thov ntawm tus neeg enterprise, koom nyob rau hauv zus tau tej cov hlau khoom uas manufactured nrog lub curvature ntawm tsis ntau tshaj li 0.2% ntawm qhov ntev. Sib ntswg ntawm lub ces kaum nyob rau hauv cov kev taw qhia nyob ib ncig ntawm lub axis yog tsis tso cai.

Lub dav ntawm lub rhawv thiab hnyav

Yuav ua li cas, nyob rau hauv qhov tseeb, yuav muaj ib tug hlau lub loj? GOST feem regulates tus piv ntawm dav rhawv ntawm cov khoom no, lawv thickness thiab qhov hnyav. Tus thawj tivthaiv yog hom twg los ntawm 20 mus rau 200 mm. Lub thickness ntawm cov khoom yuav ncav cuag 16 hli. Yuav ua li cas precisely muaj yuav tus piv ntawm lub dav ntawm lub rhawv thiab tus luj ntawm ib tug Meter ntawm cov khoom, saib lub rooj hauv qab no.

Saum toj no yog hais piv qhov tseem ceeb rau equal- khoom. Raws li koj tau pom, nyob rau tib lub dav ntawm lub thickness ntawm txee yuav tsum varied. Raws li, hloov thiab qhov hnyav. Kaum hlau tsis zoo tib qhov ntev, los yog es, nws dav "rhawv", tej zaum kuj sib txawv tsis pub dhau 20-200 hli. Tus nqi rau qhov no parameter thiab tus luj ntawm cov khoom nyob rau hauv cov ntaub ntawv no yog tswj los ntawm GOST thiab qhia nyob rau hauv tshwj xeeb ntxhuav.

steel qib

Durability hlau lub tsis tau tsuas yog nyob rau cov qauv ntawm cov siv thiab ua, lub thickness thiab dav ntawm lub txee. Nws muaj ib tug tej yam nyob rau hauv no parameter thiab ces zoo li cas ntawm cov ntaub ntawv uas twb muab siv rau qhov siv thiab ua cov khoom. Ua lub cheeb tsam ntawm lub hauv qab no hom steel:

• Carbon qub zoo;

• tsawg alloy siab zog.

Nyob rau hauv rooj plaub thawj lub hlau qhab nia, kev kawm ntawv tus yam ntxwv yog tswj GOST 380-88. Zoo hlau steels siv rau qhov siv thiab ua nkhaus, txhais GOST 19281-89.

Cov feem nrov ntau thiab tsawg pab hlau lub

Cov feem nrov cov ntawm no lub hom yog bent khoom los ntawm ferrous hlau -nees "B". Qhov kev xaiv no yog cheaper tshaj lub ces kaum ntawm stainless steel "A" cov chav kawm ntawv. Nyob rau hauv tas li ntawd, cov ces kaum hav e ib tug txaus nyab xeeb ntug rau ib tug yuav sau check thiab txhim khu kev qha kev tsim kho.

Yuav ua li cas yog cov feem ntau nrov ntau thiab tsawg pab los ntawm cov hlau ces kaum? 40 x 40 mm, 50 x 50, 70 x 70 thiab 100 x 100 mm - dav ntawm xws rhawv yog lub nrov tshaj plaws. Thawj Embodiment khoom, piv txwv li, yuav siv rau qhov siv thiab awnings, pergolas, tej, ntxhuav, thiab thiaj li txoj kev. D. Rau tsis dhau ib qho tseem ceeb lug xws cheeb tsam muaj ib tug txaus paj tau paj ntawm kev ruaj ntseg.

Cov khoom 50 x 50 hli yuav siv tau nyob rau hauv lub rooj sib txoos ntawm ntseej, rooj vag, cov ntxaij vab tshaus, me nyuam me me ua viav vias thiab t. D. Siv cov khoom siv no nyob rau hauv mechanical engineering thiab nyob rau hauv assembling w / wagons. Lub qhov ntev ntawm lub hlau bracket 50h50h5 hli los yog 50h50h6 hli cia koj mus sau tag nrho cov hom ntawm skeletons muaj me me load. Nyob rau hauv lwm yam mob, tej zaum nws yuav tsum siv tsawg check xaiv 50 x 50 x 3 los yog 50 x 50 x 4 mm. Qhov no cheeb tsam nyhav ntau thiab yog li ntawd cov nqi tsawg.

Galvanized steel bracket

Heev feem ntau cov hlau ntawm lub hom siv rau lub rooj sib txoos ntawm cov hlau Siv, thaum lub sij hawm lub lag luam yog adversely cuam tshuam los ntawm dej. Txij li thaum cov pa steel yog kev kawm mus rau xeb, nyob rau hauv cov ntaub ntawv no feem ntau siv ib tug tshwj xeeb los ntawm cov hlau lub - galvanized. Yog qhov kev xaiv no kim heev, tab sis txawm nyob rau hauv lub feem ntau nyuaj tej yam kev mob yuav kav xyoo lawm. Loj ntawm lub ntau yam hlau lub (dav thiab thickness ntawm lub rhawv) yog tib yam li hais tias ntawm lub pa.

Manufactured cov ntawm no lub hom feem ntau ntawm cov pa roj carbon hlau. Galvanizing li nws yuav tau ua nyob rau hauv ob peb txoj kev. Nyob rau hauv ib tug yooj yim immersion ces kaum nyob rau hauv lub qhuav tau khoom nrog ib tug tiv thaiv txheej thickness ntawm 150 microns. Tej zaum galvanizing yog nqa tawm nyob rau hauv ib yam thiab kaw ntim sov siab. Nyob rau hauv cov ntaub ntawv no, zinc penetrates mus rau hauv lub saum toj txheej ntawm steel, txawm hais tias tus thickness ntawm nws txheej yog tseem sib npaug zos rau 150 microns, yog khaws cia zoo npaum li cas. Tsis tas li ntawd them los ntawm no hlau steel yuav txau. Yog li ntawd nws yog tau mus thov cov ntau thicker txheej ntawm zinc - txog li ob peb millimeters.
