A3 Uzimele: intengo. A3 Uzimele: GOST

A3 ukuqinisa ekhethekile okuthiwa kwesigaba isiyingi ashisayo iphuma steel ngephrofayela gqwa senzelwe kunenze nisondelane kangcono ukhonkolo. Yinduku kuhambisana namazinga ebekwe GOST T5781-82.

incazelo jikelele

The main isici A3 ukuqinisa wukuthi kukhona izimbambo ezimbili longitudinal, okuyinto zitholakala phakathi corrugations ngesimo a "herringbone" ku ubuso bayo (ngakolunye uhlangothi nesikulufu ngakwesokunxele, ngakolunye - kwesokudla). Kukhona induku A3 izinhlelo zokusebenza ezikhethekile. Kulesi samuntu, le corrugations ubusungena one direction.

I ububanzi armature A3 angase abe ezahlukene (6-40 mm). izinduku Izacile (10 mm) zilethwa ngendlela cut izinduku, futhi ohlobo. imikhiqizo abajonqile - kuphela izinduku. Ubude yokugcina e nenye kungaba 6-12 m.

Yini eyenza

Nokufaka zingenziwa steel A3:

• Carbon izinga evamile (st.3ps, st.3sp);

• ingxubevange ongaphakeme (35GS, 25G2S).

Steel grade 35GS has a amandla isivuno 590 MPA esifushane, ukunwebeka ngesikhathi sekhefu 14% kanye namandla isivuno of 390 MPA. Y impahla 25G2S kulezi zici ziyafana ngokuhambisana GOST 5781-82 futhi ilingana 980MPa, 785MPa futhi 7%, ngokulandelana, ngokusho GOST 10884-71. A3 steel esetshenziselwa ukwenza ukuqinisa lingabhalwa izici eziningana ezinjengolwazi boron, manganese kanye magnesium.

Ububanzi bokusebenzisa

Ububanzi A3 rebar oluphakeme ezibanzi. Sebenzisa le induku:

• ukwakhiwa kwamabhuloho kanye nezinye izinhlaka ukulayishwa;

• izindlu komgwaqo;

• ukwakhiwa ubunjiniyela izinhlelo komhlaba, imigudu ye izitimela ujantshi / kaMasipala;

• Amayunithi zonke izinhlobo izakhiwo steel enhlabathini olumanzi;

• ku ukwakhiwa nokusetshenziswa civil nakwezempi ezindaweni sezulu elibuhlungu.

Lokho okwakudingeka ukuze kukhokhwe impahla

Yiqiniso, into yokuqala unake lapho uthenga induku - kuba intengo zabo. A3 nokufakwa ngokuvamile akuyona ebiza kakhulu. Intengo ke, luncike kuzinto ezimbili: ububanzi nomakhi. abahlinzeki Isitolo esidayisa yonke impahla ngokuvamile abonisa izindleko kwezingxenye amathani. Intengo rebar A3, ukuthengiswa okudayisa, kunqunywa imitha elilodwa. Ngezansi sethula wena itafula amanani entengo ezahlukeneyo evamile induku.

Yini ehlanganisiwe izindleko A3 rebar

Okungenhla kukhona amanani eseduze ukuze caskets A3 carbon steel. Kwezinye izimo, izindleko zingahluka. Intengo incike valve A3 ngokuyinhloko ku lezi zinto ezilandelayo:

• Izitembu esetshenziswa akhiqize steel. Nokufaka eyenziwe ongaphakeme-ingxubevange steel imikhiqizo ezibizayo kusukela st.3ps futhi st.3sp. Kodwa ngesikhathi esifanayo ke ihlukile, nokusebenza kangcono.

• I ububanzi we rebar. Nge ukwehla index intengo izinduku A3 iyakhula. Ngakho-ke diameters eceliwe kunazo (isib 12 mm) ngezikhathi ezithile kungenzeka ukuntula. Kulokhu intengo ibha Yiqiniso, bavuke.

• inkathi yokuthengisa. I nokufakwa eqolo A3 imele entwasahlobo - e April no-May, okungukuthi, lapho isizini ukwakhiwa kuyaqala. Isaphulelo esiphezulu yalo mkhiqizo ingatholakala ngo-December.

• Ivolumu ukuthenga. Lapho wayala iphathi enkulu kakhulu wholesale amabhizinisi, abakhiqizi nabaphakeli ungenza umthengi isaphulelo ezinhle. Ngo armature okudayisa, yebo, kuyabiza.

• indawo kokuthenga. Abathengisi izobiza ton of rebar Yiqiniso, ezibizayo kancane kuka ngokuqondile nomakhi.

Ukulinganisa zalapho (ngezimiso adjustable ubude) kuyabiza off-gage.

Okufanele funa uma uthenga

Abathengi wale mikhiqizo ufuna endaweni yokuqala kwi ilebula. Ngokwesibonelo, umuntu othile udinga 12 A3 rebar. Lokhu kusho ukuthi umuntu efuna ukuyibuyisa ngokuyithenga futhi inguqulo A3 induku ububanzi 12 mm. Imikhiqizo ezenziwe ecabanga ngokugcinwa esiqondile wonke nemithetho GOST, futhi kufanele ime ngokwezikhathi nemithetho ethile kuphela. Okokuqala nje esibekiwe induku ubukhulu ngamamilimitha awenziwanga. Okulandelayo iyinkomba yokuthi umkhiqizo isigaba langempela (kuleli cala A3). Khona-ke wabeka phansi inombolo umphini ku ngezigaba international (A400 for carbon lensimbi kanye ongaphakeme-ingxubevange ukuze A500). Futhi into wokugcina kuboniswa GOST, owawuthi armature (5781-82) Yenziwa.

Ngokwesibonelo, okufanayo 12 mm ububanzi induku yokulaya steel ongaphakeme elixutshiwe izomakwa elandelayo: A 12-III (A500) GOST5781-82. Ngokusho kwale mithetho, kungekho izincwadi ezengeziwe nezinombolo ku wokugubha A3 rebar akufanele kube.

Yini enye engingabuye ngiyenze kokwazi

Intengo sokugcina nokufakwa ethengiwe ngezinye izikhathi futhi kuncike ukubaluleka wesevisi amasevisi eyengeziwe. Lokhu kungaba, isibonelo:

• Ukuphuca nokufakwa elinikelwe ohlobo phezu izinti usayizi oyifunayo;

• ukulethwa imikhiqizo uthenge.

amaqoqwana elikhulu rebar ithengiswe, njengoba umthetho, ingathunyelwa yisiphi isifunda yezwe. Melkooptovye nabathengisi enze ukulethwa ngokuvumelana edolobheni esithile noma endaweni.

Uma ukuthenga impahla, phakathi kwezinye izinto, ukubuza nomthengisi isitifiketi. A3 ukuqinisa kufanele abe nezici ncamashi elihambisana nezidingo GOST.

ukusebenza Ukucaciswa

A3 rebar ukwanda phakathi abakhi ngokuyinhloko ngenxa yokuthi ukusetshenziswa kwalo kwenza kube nokwenzeka ukwakha eyizingqabavu kakhulu futhi iqine izakhiwo zikakhonkolo. Ngaphezu A3 induku, umkhakha yesimanje ukhiqiza samuntu A1. Lokhu lwemidlalo has corrugations. Ngenxa yalokho, izinga adhesion ukuze ukhonkolo ngezansi. ukuqinisa A3 A1 uvame ezisetshenziselwa ukwakha izinhlobo ezahlukene kwagcizelela izakhiwo zikakhonkolo. Kulesi nguqulo ye-A1 ngokuvamile ezisetshenziselwa ukwakha izinhlobo ezihlukahlukene zezindwangu ezingaba amalungu asizayo, futhi A3 - ukulayishwa. Ngokwesibonelo, kuba inketho yokugcina kumele isetshenziswe lapho ethela izisekelo izakhiwo. Ngaphezu ngezinga eliphezulu adhesion kuya ukhonkolo, ukuqinisa A3 unezinye izinzuzo ezithile.

1. Kusukela ucwezana futhi emaphethelweni transverse of izinduku musa aphambana, indaba ngamandla eliphezulu futhi ductility ngisho ezahlukene.

2. Isetshenziswa valve A3, izimfanelo okuyinto mikhulu kungaba cishe kunoma yimiphi imibandela. Lokhu induku akaphelelwa amandla ayo ngisho ezingeni lokushisa -55 degrees.

3. Inketho A3 induku carbon steel kungenziwa ashiselwe kalula. Ngaphansi kwezimo ezithile kungenzeka ukuxhuma izinduku enjalo A3 futhi ongaphakeme ingxubevange steel.

amazinga GOST

Ngo womshini A3 rebar izidingo esiyisibopho GOST ezilandelayo kumele kwenziwe:

• Ugobile izinduku kumele singeqi 0.6% we obuphelele elinganisiwe.

• Phezu kobuso izinduku izimbambo akufanele ube imifantu, ugingqe eyisithunjwa noma kwelanga.

• Ukuze womshini induku ukuze kusetshenziswe carbon steel elihambisana GOST amazinga 380. I izici esithunyweni ongaphakeme ingxubevange steel zinqunywa lolutfolakala kumathebula ekhethekile.

Ukuze steel induku A400 25G2S avunyelwe nokwehla kwamandla eqine ukuba 560 MPA.

Packing izinduku ngokuvumelana GOST

I-oda le nqubo futhi kulawulwa GOST. nokufakwa A3 igcwele kuhambisana lezi ziqondiso:

• mass umsipha ukuqinisa izinduku kumele singeqi 15 m;

• izinyanda vala wire kuphela noma ngocingo induku;

• ngesicelo Amabha kungenziwa zahlanganiswa ngo izinyanda 3 m noma 5 m;

• kunqwaba ngayinye kufanele alengiswe ilebula ebonisa A3 ekilasini.

iziqondiso zokuhamba

A3 kungenziwa athuthwe nokufakwa kokubili imigwaqo emikhulu nojantshi bezitimela. Lapho ukulayisha kanye athula liyadingeka ukuthi imikhiqizo kwakungafanele nganoma isiphi isizathu zikhubazekile noma ubhujiswe.

Elondolozwe umphini A3 emafektri nge umswakama evamile noma encishisiwe. Gcina ngqo phansi akuvunyelwe iziqondiso. Kufanele kugcinwe amaphakethe Pallets sokhuni noma emashalofini. Lapho ebeka kufanele ukuthi ayikho leyo nto akusho ehle.
