Armature 12. siv cov kev faib fittings: ntau lawm, qhov hnyav, nqe

Armature hu ua steel khoom muaj rau hauv daim ntawv ntawm ib tug ntev pas nrig nrog ib tug yeej seem. Lub hom phiaj tseem ceeb ntawm no hom ntawm ntev steel yog los txhim kho lub zoo ntawm lub pob zeb ua lug. Muaj ob peb hom ntawm qhov cuab lub zog, txhua tus uas yog ua nyob rau hauv nruj raws li cov GOST qauv.

lub sij hawm

Qhob - ib cov khoom tsis tshua muaj neeg check compression. Cam khwb cia nyob rau hauv nws tsim yuav kiag li tsis muaj mob los mus tiv lub enormous ceeb thawj. Txawm li cas los, Tu siab, lub tensile khoom yog heev nkig, tib txoj kev raws li nyob rau hauv dabtsi yog khoov. Vim hais tias ntawm no feature nyob rau hauv kev tsim kho ntawm qhob vaj tse thiab lug yuav tshwm sim tau teeb meem ntau.:. Ntes qab daus phab ntsa thiab los ntawm tej yam uas cov caij nplooj ntoos hlav rog ntawm o, degradation ntawm sib tshooj vim siab dhau heev lawm ntsug load, thiab lwm yam Cov tensile lub zog ntawm qhob no tsuas yog 10-15 % ntawm cov compressive zog.

Qhov teeb meem no, thiab aims kom daws tau qhov hlau fittings. Coefficient ntawm thermal expansion ntawm lub steel ze rau lub pob zeb taw qhia. Qhov no ua rau nws tau siv cov ntaub ntawv nyob rau hauv lub complex. Qhov tseem nyob rau hauv coob nyob rau hauv uas tsis muaj-sawv lub tsev yog ib tug haum 12 hli nyob rau hauv txoj kab uas hla. Qhob Siv, fortified txog ntas therefrom, yog yus muaj los ntawm high compressive zog thiab yog li - tau tensile.

Nrog rau qhov kev tsim kho ntawm lub hauv paus, uas dab tsi rau cov load thaum lub sij hawm lub caij nplooj ntoos hlav ntawm o, siv fittings - yuav tsum tau mob. Feem ntau qhov no hom ntawm cov hlau siv thiab cov kev tsim kho ntawm phab ntsa (strengthening ntawm masonry, lub sab sauv siv rigidity). Qhov cuab lub zog nyob rau hauv daim ntawv ntawm cov mesh siv thaum pouring plag tsev thiab screeds. Thiab thov nws nyob rau hauv qhov siv thiab ua kev ua vaj tse paths, pavings thiab thiaj li nyob. D. Nrog kev tsim kho ntawm multi-storey vaj tse thiab tsev nyob rau cov teeb meem xau yog feem ntau siv li qub 16 hli los yog ntau tshaj tuab.

Ntawm lwm yam, qhov no zoo ntawm hlau ntawm lwm thiab pab txoj kev ib tug qhia xws li cov qaug zog lub zog ntawm lub pob zeb ua, raws li zoo li kuj mus txhua yam kev nyuaj siab lug nraum zoov.

khoom

Txij li thaum lub fittings - ib tug tseem ceeb heev lub caij ntawm ua kev reinforced lub tsev lug, rau nws zoo tshwj xeeb uas yuav tsum tau. Cov raw khoom rau zus tau tej cov hom hlau ntawm ib tug tshwj xeeb reinforcing hlau. Yuav kom txhim kho txoj kev txhua yam khoom nws yog doped nrog manganese thiab silicon. Yuav kom ua lub haum ntawm tshwj xeeb lub zog yog ua titanium thiab chromium kev kho mob.

Ntau yam nyob rau txoj kab uas hla

Lub qhov cuab lub zog siv tej zaum yuav siv nrog txawv thickness. Nyob rau hauv no hais txog, muaj ntau yam cai uas cov kev cai SNIP. Yog li, piv txwv li, rau cov me nyuam yaus ntawm vaj tse nrog ib lub teeb heev ncej-by ntaub thaiv npog phab ntsa tsa rau ruaj khov hauv av yuav siv tau nyob rau hauv lub tuav ntawm 10 hli inch. Thaum lub sij hawm qhov kev siv ntawm ntiag tug tsev suab tag nrho cov lwm yam, raws li twb tau hais, yog siv li qub 12 hli.

Hom raws li cov qauv ntawm cov raug

Qhuav ntawm 12 hli rebar (hlau), raws li zoo raws li lwm yam rods thickness, muaj ob lub ntsiab yees:

• Los ntawm kub dov lub hlau. Tej khoom uas yog hu ua pas nrig.
• Los yog nqus steel txias. Qhov no thiaj li hu ua hlau saib.

Siv ntawm armature 12 mm - tus txheej txheem yog tsis dhau txoj, tab sis yuav tsum tau siv tshwj xeeb cov khoom thiab leej ua raws li nrog tag nrho cov nteg technology.

Npaj-ua ntas thiab mesh nyob rau tshwj xeeb qhauj. Tus txheej txheem rau lawv siv thiab muaj xws li cov nram qab no theem:

• Yog hais tias qhov khoom yog nkag nyob rau hauv yob, ua unwinding.
• Tau wires hlau los yog rods.
• Qhov cuab lub zog yog txiav mus rau qhov kev kawm ntev. Qhov no thiab yav dhau los ua hauj lwm yog ua kom nyob rau hauv tshwj xeeb tej machine.
• Qhov no yog ua raws li los ntawm los ua ke rau ntawm tus ncej ntsiab los yog rau hauv daim phiaj. Qhov no lub lag luam yog ua rau tshwj xeeb vuam machine. Nyob rau hauv tej rooj plaub lub ntsiab yog kev cob cog rua los ntawm txoj kev ib phau ntawv welding.

Tej zaum reinforcing tuav thiab meshes yog manufactured thiab ncaj qha mus rau qhov kev siv ntawm cov vaj tse (feem ntau yog cov uas tsis muaj-sawv). Nyob rau hauv cov ntaub ntawv no, tus qauv yuav tsum welded los yog hlau. Tus thawj txoj kev yog tsawg laborious. Thaum ob thav duab yog ib tug ntau ruaj. Qhov tseeb yog tias nyob rau hauv lub teb ntawm Vuam steel rusts sai sai tom qab.

nto hom

Nyob rau qhov no vim qhov txawv tsuas yog ob tug hom ntawm 12 hli li qub:

• Du, yog ib tug pa rods los yog puag ncig tus ntoo khaub lig-section hlau.
• Corrugated. Nyob rau saum npoo ntawm xws li ib tug valve nws yog transverse (feem ntau crescent) thiab longitudinal ribs. Xws li ib tug tsim tso cai rau kom lub adhesiveness nrog lub pob zeb ncej neeg.

Hom kev ua hauj lwm tej yam kev mob

Lub ntas kheev siv lub nram qab no ntawm fittings:

• faib;
• Ua hauj lwm (ua tau 12 hli rods);
• los ua ke;
• collars.

Nyob rau hauv cov nqe lus ntawm lub lag luam li qub 12 hli yog muab faib mus rau hauv:

• Lim. Siv thaum tsim nyog tshwj xeeb durability ntawm qhob lug (nyob rau hauv av qeeg-nws qhov chaw, high-sawv vaj tse nyob rau hauv lub qab nthab, nyob rau hauv lub raug ntsug load ntawm tus choj thiab t.).
• Free ntawm nro. Teem tsis prestressing. Nws yuav siv nyob rau hauv cov pa qhob lug.

Nyhav armature 12 hli

Nrog kev tsim kho ntawm ib tug me me muaj pes tsawg tus ntawm ntiag tug vaj tse ntawm cov hlau yuav tsum tau yog feem ntau xam nyob rau hauv khiav meters. Manufacturers feem ntau muag rebar ceeb thawj. Qhov no tej zaum yuav ua rau ib co teeb meem nyob rau hauv cov lus teb. Nyob rau hauv thiaj li yuav nrhiav tau tawm yog yuav ua li cas muaj ntau yam kilograms ntawm qhov cuab lub zog yog tsim nyog nyob rau hauv ib tug cov ntaub ntawv, nws yog tsim nyog los muab tus luj ib Meter ntawm qhov yuav tsum tau cov ntaub ntawv uas ntev. Tus thawj tivthaiv nyob rau hauv lub hom qhov cuab lub zog thiab txhais los ntawm tshwj xeeb ntxhuav.

Yog li, lub armature 12 hli ceeb thawj (nyob rau hauv raws li cov GOST) yog 0,89 kg / khiav 'meter'. Wb hais tias koj xav mus ntiav 25 m rau qhov kev siv ntawm lub tsev. Thiaj li, qhov yuav tsum tau mus yuav 25 x 0.89 = 22.25 kg rods.

Npav thiab nqi ntawm fittings

Du hlau 12 hli tsiaj ntawv A1, fluted tsis xuas nrig ntaus - A3. Tsis tas li ntawd, lub npav yuav tau pom armature raug qauv (A - goryachekatnaya, B - ua txias kev) thiab siv steel stamp (xaus-npawb tsab). Tauj cov khoom tau nyob rau hauv coils los yog tuav. Piv txwv li, lub los cuab lub zog "A3 A500S" yog txhais raws li nram no:

• cov ntaub ntawv uas muaj ib tug corrugated nto (A3),
• manufactured los ntawm kub dov (A),
• steel qib - 3PS (A500S)

Tus nqi ntawm no hom ntawm cov hlau nyob feem ntau nyob rau hauv nws cov thickness raws li zoo raws li lub cim. Yuav ua li cas npaum li cas yuav raug nqi li qub 12? Tus nqi ntawm xws txoj kab uas hla rods - goryachekatnye (nrov tshaj plaws daim ntawv no) - los ntawm ntau lwm yog nyob rau hauv lub chav txog 22-29 txhiab rubles ib tuj .. Ntawm cov hoob kawm, thaum yuav tsum nug tus neeg muag khoom muaj ib tug daim ntawv pov thawj ntawm kev ua raws cai nrog GOST. Npav rau lub valve yog feem ntau affixed txawm thaum lub sij hawm dov. Yog hais tias zus tau tej cov rods thiab tuav no twb tsis tau ua, lawv xaus cim nrog indelible number case. Yog li ntawd, piv txwv li, steel A500S yog cim nrog dawb thiab xiav, A600S - daj thiab dawb, thiab thiaj li nrhiav tau lub caij nyoog match rau lwm yam hom pas nrig yuav ua tau tshwj xeeb ntxhuav ...

Yog li, lub fittings - ib qho ntawm feem nrov nyob rau hauv lub lag luam, hom ntawm cov hlau - yuav tau ua nyob rau hauv ntau txoj kev los ntawm ntau qib ntawm steel, muaj ib tug tus los yog grooved nto, yuav tuab los yog nyias. 12 hli rods yog cov feem ntau nrov ntau ntau yam. Thaum yuav lawv, raws li zoo raws li lub tshaaj ntawm lwm yam cuab lub zog, yuav tsum xub ntawm tag nrho cov xyuam xim rau cov npav thiab nto hom.
