A3 maziko: mtengo. A3 maziko: GOST

A3 wapadera zolimba otchedwa zozungulira gawo otentha adagulung'undisa zitsulo ndi mbiri zodziwitsa anafuna kulumikiza bwino ndi simenti. Ndodo anapanga kugwilizana ndi zotchulidwa GOST T5781-82 mfundo.

mafotokozedwe ambiri

Waukulu mbali A3 zolimba kuli awiri nthiti kotenga, yomwe ili pakati corrugations mu mawonekedwe a "herringbone" pamwamba pake (pa dzanja limodzi ndi kumanzere wononga, pa zina - kumanja). Komanso pali A3 ndodo ntchito yapadera. Mu chimake izi, corrugations akalowe njira imodzi.

The awiri a armature A3 mwina osiyana (6-40 mm). ndodo woonda (10 mm) zaperekedwa mu mawonekedwe a ndodo odulidwa, ndi coils. Wandiweyani mankhwala - yekha mu ndodo. M'litali yotsirizira mu umodzi ndi nkhani zina kungakhale 6-12 m.

Kodi n'chiyani chinachititsa

Zovekera akhoza zopangidwa ndi zitsulo A3:

• Mpweya yachibadwa khalidwe (st.3ps, st.3sp);

• otsika aloyi (35GS, 25G2S).

Zitsulo kalasi 35GS ali ndi zokolola mphamvu ya 590 MPa lalifupi, elongation pa kutulukira kwa 14% ndi zokolola mphamvu ya 390 MPa. Y zinthu 25G2S makhalidwe amenewa ali yemweyo malinga ndi GOST 5781-82 ndi wofanana 980MPa, 785MPa ndi 7%, motero, monga GOST 10884-71. A3 zitsulo ntchito kupangira zolimba akhoza mbali monga boron, manganese ndi magnesium.

Kuchuluka kwa ntchito

Mbali A3 rebar ndi zinthu zambiri. Ntchito ndodo iyi:

• yomanga milatho ndi nyumba zina yodzaza;

• msewu amaika mumsewu;

• yomanga machitidwe mobisa zomangamanga, una wa kwa sitima sitima / okwerera sitima;

• mayunitsi a mitundu yonse ya nyumba zitsulo m'nthaka lonyowa;

• ntchito yomanga nyumba ya ntchito zaboma ndi asilikali m'madera nyengo nkhanza.

Mtengo wa zinthu

Kumene, chinthu choyamba inu kulabadira pamene kugula ndodo - ndi mtengo. A3 zovekera ambiri si mtengo kwambiri. Mtengo zimatengera makamaka pa zinthu ziwiri: m'mimba mwake ndi Mlengi. wosamalira yogulitsa zambiri amasonyeza mtengo kwa nkhani matani. Mtengo wa rebar A3, anagulitsa pa ritelo, anatsimikiza ndi mita imodzi. Pansipa ife inu tebulo ndi mitengo ya mitundu yofala ndodo.

Kodi m'gulu la mtengo wa A3 rebar

Pamwamba ndi mitengo oyerekeza kuti caskets A3 mpweya zitsulo. Nthawi zina, mtengo angakhale osiyana. Mtengo zimadalira vavu A3 zimagwiritsa zifukwa zotsatirazi:

• Stamps ntchito popanga dzimbiri. Zovekera zopangidwa otsika-aloyi zitsulo zodula kwambiri malonda st.3ps ndi st.3sp. Koma pa nthawi yomweyo ndi osiyana, ndi ntchito bwino.

• The awiri a rebar lapansi. Ndi kuchepa kwa malipiro index mu ndodo A3 ukuwonjezeka. Motero diameters kwambiri anapempha (mwachitsanzo, 12 mm) nthawi kumachitika akusowa. Pankhaniyi mtengo wa mowa, ndithudi, adzauka.

• nyengo malonda. The zovekera mtengo kwambiri A3 waima m'chaka - mu April ndi May, kuti, pamene yomanga nyengo akuyamba. Kuchotsera pazipita kwa mankhwala akhoza zopezera December.

• Volume kugula. Pamene kulamula gulu lalikulu kwambiri malonda yogulitsa, opanga ndi ogulitsa mungapange wogula kuchotsera wabwino. Mu armature ritelo, ndithudi, ndi okwera mtengo kwambiri.

• malo kugula. Bongo ndalama tani rebar, ndithudi, mtengo pang'ono kuposa mwachindunji kwa Mlengi.

Kuyeza mindandanda yamasewera (ndi magawo chosinthika kutalika) ndi zodula kuchokera-gage.

Kodi kuyang'ana pamene kugula

Ogula katundu izi akufunafuna mu malo oyamba pa chizindikiro. Mwachitsanzo, munthu wina akufunika 12 A3 rebar. Izi zikutanthauza kuti munthu akufuna kugula mabuku a A3 ndodo awiri a mamilimita 12. Zamgululi zopangidwa ndi mwambo lenileni la malamulo onse GOST ayenera zaikidwa mogwirizana ndi malamulo ena. Mu malo oyamba mwachindunji ndodo awiri mu millimeters akuyendera. Kenako kumasonyeza wa kalasi leni mankhwala (mu nkhani iyi A3). Ndiye mulembe nambala vavu mu gulu lonse (A400 kwa zitsulo mpweya ndi otsika-aloyi kwa A500 kwa). Ndipo chinthu chotsiriza akusonyeza GOST, malinga ndi zimene armature (5781-82) zinalengedwa.

Mwachitsanzo, yemweyo 12 mamilimita awiri ndodo ya alloyed zitsulo otsika siidzasoŵa motere: A 12 III (A500) GOST5781-82. Malinga ndi malamulo, palibe m'makalata ena ndi manambala mu kulemba A3 rebar sayenera.

Kodi aliyense ndi ofunika podziwa

Mtengo chomaliza cha zovekera anagula ndi zina chimadaliranso mtengo wa athandizi a ntchito zina. Izi zikhoza kukhala Mwachitsanzo:

• Kudula zovekera amaperekedwa mu coils pa ndodo ya kukula anakhumba;

• yoperekera katundu anagula.

magulu Large wa rebar anagulitsa, monga ulamuliro, ungathe kutumizidwa kwa dera lirilonse la dzikolo. Melkooptovye ogulitsa kuchita yobereka monga mzinda makamaka kapena malo.

Pamene inu kugula zinthu, mwa zina, kufunsa wogulitsa kalata yothetsera. A3 zolimba ayenera makhalidwe ndendende lolingana zofunika za GOST.

specifications ntchito

A3 rebar kutchuka mwa omanga makamaka chifukwa chakuti ntchito limachititsa kumanga kwambiri wangwiro ndi cholimba nyumba konkire. Kuwonjezera pa ndodo A3, mafakitale zamakono umabala chimake A1. fixture uyu ali corrugations. Choncho, mlingo wa guluu wolimba ndi simenti pansipa. A3 ndi A1 zolimba nthawi zambiri ntchito yomanga zosiyanasiyana nyumba analimbitsa simenti. Mu buku lino la A1 ndi amagwiritsidwa ntchito yomanga zamitundu yosiyanasiyana mamembala wothandiza, ndipo A3 - yodzaza. Mwachitsanzo, ndi njira masika ayenera kugwiritsidwa ntchito ngati kuthira maziko a nyumba. Kuwonjezera digiri yapamwamba ya guluu wolimba kwa simenti, ndi zolimba A3 ali ndi ubwino wake.

1. Popeza kachigawo ndi m'mbali yopingasa ndodo alibe intersect, chuma ndi mphamvu yapamwamba ndi ductility ngakhale osiyana.

2. Unathandizira mavavu A3, makhalidwe amene ali wamkulu, mukhoza pafupifupi zinthu aliyense. ndodo iyi sasiya mphamvu ngakhale pa kutentha madigiri -55.

3. Yankho A3 ndodo mpweya zitsulo mosavuta welded. Pa zochitika zina n'zotheka kulumikiza ngati ndodo A3 ndi otsika aloyi zitsulo.

mfundo GOST

Mu kupanga A3 rebar amafuna kuvomerezedwa GOST zotsatirazi ayenera kukwaniritsa:

• Kupindika ndodo sayenera upambana 0,6% cha kutalika mpandawo.

• Pamwamba pa ndodo nthiti sayenera ming'alu, ukapolo anagubuduza kapena likamalowa.

• Kupanga ndodo kuti ntchito mpweya zitsulo lolingana GOST mfundo 380. The makhalidwe ankafunika aloyi zitsulo otsika atsimikiziridwa ku matebulo wapadera.

Chifukwa zitsulo ndodo A400 25G2S analola kuchepa mphamvu kwamakokedwe kwa 560 MPa.

Atanyamula ndodo malinga GOST

Dongosolo la njirayi amadziwikanso malamulo ndi GOST. zovekera A3 odzaza zoletsedwa ndi malamulo awa:

• misa mitsempha zolimba ndodo sayenera upambana 15 mamita;

• mitolo Mangani yekha waya kapena waya ndodo;

• pa pempho mipiringidzo akhoza mmatumba mu mitolo ya 3 mamita kapena 5 mamita;

• lililonse mtolo ayenera kupachikidwa pa chizindikiro kusonyeza kalasi A3.

malamulo zoyendera

A3 akhoza kusamutsidwa zovekera onse msewu ndipo njanji. Pamene potsegula ndi katundu chofunika kuona kuti zinthu sizinali chifukwa chilichonse olumala kapena kuwonongedwa.

Kusunga vavu A3 mu malo ndi chinyezi labwinobwino kapena yafupika. Kusunga mwachindunji pansi ndikoletsedwa malamulo. Zovekera ziyenera kusungidwa mapaketi pa pallets matabwa kapena maalumali. Pamene atagona ayenera kuona kuti palibe zakuthupi si sag.
