A3 Isakhelo: ngexabiso. A3 Isakhelo: Standard

nokuqiniswa ekhethekileyo A3 ebizwa setyhula icandelo shushu waqengqela kuhlinzwa inkangeleko ngamaxesha eyenzelwe lib ngcono eziphathekayo. Intonga zenziwa ngokwemimiselo nemigangatho emiselwe GOST T5781-82.

incazelo jikelele

Owona msebenzi A3 unyanzeliso kukuba kukho ezimbombeni zaso ezimbini longitudinal, ezithi zibekwe phakathi corrugations eluhlobo i "herringbone" kumphezulu wayo (kwelinye icala ngesilungelelanisi ngasekhohlo, kwelinye - ekunene). Kukho kwakhona ngentonga A3 for izicelo ezizodwa. Kulo ngobuwena, le corrugations uhambe kwicala elinye.

Sangqa armature A3 ukuze ezahlukeneyo (6-40 mm). iintonga Thin (10 mm) zinikezelwa ngohlobo kweentonga aqingqiweyo, kwaye jiko. iimveliso ashinyeneyo - kuphela obusezintongeni ezo. Ubude yokugqibela omnye kunye nomnye kunokwenzeka 6-12 m.

Yini wenza

Izixhobo zingenziwa A3 mhlwa:

• Ikhabhoni ubunjani obuqhelekileyo (st.3ps, st.3sp);

• ingxubevange ephantsi (35GS, 25G2S).

grade Steel 35GS kukho amandla isivuno 590 MPA mfutshane, zobude ngexesha lekhefu ka-14% yaye amandla hoxa ka 390 MPA. impahla Y 25G2S ezi mpawu ziyafana ngokungqinelana GOST 5781-82 kwaye ulingana 980MPa, 785MPa ne-7%, ngokulandelelana, ngokutsho GOST 10884-71. A3 steel esetyenziselwa ukwenza unyanzeliso ungase wakhiwe ngezinto ezifana boron, manganese nezinki.

Ububanzi bokusebenzisa

Scope A3 rebar yi ebanzi. Sebenzisa le ntonga;

• ukwakhiwa iibhulorho kunye nezinye izakhiwo zithwele;

• yokukwazi endleleni;

• zokwakha iinkqubo zobunjineli phantsi komhlaba, imigudu ye oololiwe kaloliwe / metro;

• iiyunithi zonke iintlobo zezakhiwo ophuma komhlaba;

• kwi ukwakhiwa kwezakhiwo ukusetyenziswa yoluntu zomkhosi kwiindawo kwimozulu ngqwabalala.

Iindleko zokufunda

Kakade ke, into yokuqala uhlawula ingqalelo xa uthenga ngentonga - yinto ixabiso labo. izixhobo A3 ngokubanzi nto ibiza kakhulu. Ixabiso kuba kuxhomekeke ikakhulu kwizinto ezimbini: i ubukhulu kunye nomakhi. Ababoneleli Wholesale ngokuqhelekileyo ibonisa iindleko eziphathekayo ngeetoni. Ixabiso rebar A3, makuthengiswe ngawo ngemiyinge emincinci, kuxhomekeke semitha enye. Ngezantsi sinikela kuwe etafileni amaxabiso ezo Ukrainian lunee ntlobo zixhaphakileyo yentonga.

Yintoni ifakiwe kwixabiso A3 rebar

Le angentla amaxabiso uqikelelo ukwenzela caskets A3 carbon ngentsimbi. Kwezinye iimeko, iindleko zinokuba nomahluko. Ixabiso ixhomekeke ivelufa A3 ikakhulu kwezi zinto zilandelayo:

• Izitampu kusetyenziswa ukuvelisa ngentsimbi. Izixhobo ezenziwe ezisezantsi ingxubevange sobhedu iimveliso abizayo ezivela st.3ps kunye st.3sp. Kodwa kwangaxeshanye, yahlukile, kunye nokusebenza okungcono.

• Ubukhulu be rebar. Kunye nokuncipha kwe-indeksi yamaxabiso ezo A3 uchatha. Ngaloo ndlela ngobubanzi ezininzi eceliweyo (umz, 12 mm) ukususela kumaxesha ngamaxesha kungenzeka intswelo. Kulo mzekelo ixabiso bar, kakade, vuka.

• ixesha yokuthengisa. Ezifakwe kuyabiza A3 umi entwasahlobo - ngo-Apreli nangoMeyi, oko kukuthi, xa ngexesha lokwakha iqala. Le isaphulelo eliphezulu le mveliso zingafumaneka ngoDisemba.

• Volume ukuthenga. Xa zi-odola iqela elikhulu kakhulu amashishini ihoseyile, abenzi nabathengisi zingenza umthengi isaphulelo elungileyo. Xa armature ngemiyinge emincinci, Kakade ke, kuyabiza kakhulu.

• kwindawo oyithenge kuyo. Abathengisi uya kubiza Ndiziva rebar, kakade, ebiza kakhulu kancinane ngqo evela kumenzi.

Measuring emidlalweni (kunye adjustable parameters ubude) ibiza kakhulu off-yobu-.

Yintoni ukujonga ukuba xa bethenga

Abathengi ezi mveliso bafuna kuba kwindawo yokuqala kwileyibhile. Ngokomzekelo, umntu kufuneka 12 A3 rebar. Oku kuthetha ukuba umntu ufuna ukuthenga luguqulelo oluphambi A3 intonga sangqa 12 mm. Iimveliso ezenziwe ngokugcinwa ngqo yonke imimiselo ka GOST, kwaye zizakuboniswa ngokungqinelana nemithetho ethile. Kwimeko yokuqala indawo elikhankanyiweyo intonga bepali ku ngemilimitha zaphunyezwa. Okulandelayo kubonisa lodidi imveliso eyiyo (kulo mzekelo A3). Emva koko wabeka phantsi inombolo ivalve kwi ngokolwahlulo ngamazwe (A400 ngenxa carbon zentsimbi kunye ephantsi-ingxubevange ngenxa A500). Kwaye into yokugqibela kubonisiwe GOST, njengoko apho armature (5781-82) yaveliswa.

Umzekelo, ngokufanayo 12 mm ubudeki intonga ngentsimbi ephantsi exutyiweyo ziya kumakishwa ngolu hlobo lulandelayo: A-12 III (A500) GOST5781-82. Ngokutsho kwimimiselo, akukho oonobumba ezongezelelweyo kunye neenombolo kumakisha A3 rebar kufuneka kungabi.

Yintoni enye ukufuna ukwazi into

Ixabiso lokugqibela lwezilinganisi ezithengiweyo ngamanye amaxesha zixhomekeke ixabiso lomniki-nkonzo ngeenkonzo ezongezelelweyo. Oku kunokuba, umzekelo:

• armatures olunikwe jiko phezu iintonga ubukhulu efunekayo;

• nokuhanjiswa izinto ezithengiweyo.

iibhetshi amakhulu rebar wathengisa, njengokuba umthetho, zingathunyelwa nawuphi na ummandla kweli lizwe. Melkooptovye abathengisi ukwenza unikezelo ngokungqinelana umzi othile okanye indawo.

Xa uthenga impahla, phakathi kwezinye izinto, ukuba cela umthengisi isiqinisekiso. A3 nokuqiniswa kufuneka iimpawu ngqo ehambelana neemfuno GOST.

iinkcukacha yokusebenza

A3 rebar ngokuthandwa phakathi abakhi kubangelwe ikakhulu yokuba ukusetyenziswa kwayo kwenza kube lula ukwakha izakhiwo eziphathekayo kakhulu irobust ezongeziweyo kunye ixesha elide. Ukongeza A3 intonga, ishishini mihla uvelisa ngobuwena A1. Lo mdlalo corrugations. Ngenxa yoko, izinga adhesion ukuya eziphathekayo ngezantsi. nokuqiniswa-A3 kwakunye A1 amaninzi asetyenziswe ekwakheni iintlobo ezahlukeneyo zezinto ezakhiweyo ufakelo lwesamente. Kolu guqulelo lwe A1 uqobo asetyenziswe ekwakheni iintlobo ngeentlobo yamalungu abangabancedani, yaye A3 - zilayishwe. Umzekelo, lo ngowona ukhetho wokugqibela kufuneka ingasetyenziswa xa agalele iziseko zezakhiwo. Ukongeza ukuya kwiqondo eliphezulu adhesion ukuya eziphathekayo, kugunyaziso A3 kunenye iingenelo.

1. Ekubeni iceba kunye kungqameko ezinqamlezayo emahlamvini musa phambana, izinto ngamandla ephakamileyo ductility nokuba ezahlukeneyo.

2. Esisebenza valve A3, iimpawu imikhulu, unako phantse naziphi na iimeko. Le intonga angalahlekelwa amandla kwayo kubushushu degrees -55.

3. Option A3 intonga carbon zentsimbi kube lula omthuqwa. Phantsi kweemeko ezithile kunokwenzeka ukudibanisa loo iintonga A3 nezisezantsi ingxubevange ngentsimbi.

amazinga GOST

Ekwenziweni A3 rebar iimfuneko zomthetho ze GOST zilandelayo:

• Ugobile kweentonga akufuneki igqithe 0.6% ye ubude elilinganisiweyo.

• Kumphezulu kweentonga iimbambo kufuneka kungabikho iintanda, ehlelayo mthinjwa, okanye kwelanga.

• Kuba nokuveliswa yentonga ezakusetyenziswa carbon yesinyithi ehambisana GOST imigangatho 380. Ezi mpawu efunekayo intsila sentsimbi esezantsi bamiliselwa iitafile ezizodwa.

Kuba intonga steel A400 25G2S ukuba ukwehla olunamandla ukuya 560 MPA.

Ukupakisha iintonga ngokwe GOST

Umyalelo yale nkqubo nako kulawulwa yi GOST. izixhobo A3 zipakishwe ukuthobela le migaqo:

• iintonga lungu nokuqiniswa mass mayingabi ngaphezu 15 m;

• iinyanda uwafake wire kuphela okanye ucingo intonga;

• ngesicelo imivalo nga kufakwa zizithungu, ka-3 m okanye 5 m;

• isiqhuma ngalinye baxhonywe kwileyibhile ebonisa A3 eklasini.

imimiselo yezothutho

A3 ube nokuhanjiswa izixhobo zombini ezisebenzisa indlela kwanezo zisebenzisa umzila. Xa kufuneka ukukhweliswa nokothula ukubona ukuba iimveliso hayi ngenxa yaso nasiphi na isizathu gqitha okanye yatshatyalaliswa.

Egcinwe valve A3 ezikwindawo yokugcina impahla nokufuma eqhelekileyo okanye lincitshiswe. Ukugcina ngqo emhlabeni akuvumelekanga mimiselo. Izixhobo kufuneka zigcinwe iipakethe kwi pallets ngomthi okanye ezishelifini. Xa nithi, kufuneka abone ukuba akukho nanye impahla akuthethi SAG.
