A3 Frame: mutengo. A3 Frame: GOST

A3 chisimbiso chaiyo inonzi dzeraundi chikamu inopisa ndokukungurusira simbi pamwe kwenguva nenguva Profile aiendeswa nani chokuedza pamwe kongiri. A tsvimbo yakaitwa achiita zvaidiwa nemitemo ushandiswe nokuda GOST T5781-82.

tsananguro mukuru

Huru Pakanzi A3 chisimbiso ndechokuti pane longitudinal pakona maviri, izvo riri pakati corrugations ari muchimiro "herringbone" riri ayo nechepamusoro (kurutivi rumwe ruoko mumwe kuruboshwe sikuruu, kurutivi rumwe - kurudyi). Panewo imwe A3 shamhu chaiyo mafomu. In musimboti ichi, kuti corrugations anogona kupinda imwe chete.

The dhayamita pamusoro armature A3 vangava zvakasiyana (6-40 mm). Mutete tsvimbo (10 mm) akaiswa muchimiro akavezwa tsvimbo, uye mune Coils. Gobvu zvigadzirwa - chete maari. Kureba yokupedzisira imwe nedzimwe mhosva kungava 6-12 m.

Chii chakaita

Fittings zvinogona kuitwa simbi A3:

• Carbon Muzvarirwo unhu (st.3ps, st.3sp);

• yakaderera chiwanikwa (35GS, 25G2S).

Steel mugwaro 35GS ane goho simba 590 MPa pfupi, elongation panguva yokumbozorora 14% uye ine goho simba pamusoro 390 MPa. Y zvinhu 25G2S maitiro aya ndiwo chete maererano GOST 5781-82 uye akaenzana 980MPa, 785MPa uye 7%, ukuwo, maererano GOST 10884-71. A3 simbi inoshandiswa pakuita chisimbiso ringaumbwa kuti zvinhu zvakadai Boron, manganese uye magnesium.

Makuriro Akaita kushandiswa

Makuriro A3 rebar iri chaizvo rwakafara. Shandisa tsvimbo iyi:

• kuvaka mabhiriji nedzimwe nhengo vakaremerwa;

• mugwagwa tichigadzira;

• kuvakwa pachivande okugadzira mugadziriro, tunnels nokuti zvitima njanji / Metro;

• vamapoka kwemarudzi ose simbi hurongwa mu ivhu nyoro;

• pakuvaka zvivako dzevagari uye uto kushandiswa munzvimbo pamwe kudzi- utsinye.

Mari zvinhu

Chokwadi, chinhu chokutanga kuteerera kana kutenga tsvimbo - ndiko mutengo wavo. A3 Fittings zvavo hakusi zvinodhura. The mutengo nokuti kunonyanya zviviri on: yacho dhayamita uye kambani. Wholesale rinobatsirwa kazhinji anoratidza mari kwemashoko mu matani. Mutengo rebar A3, kutengeswa nomutengo Retail, akatsunga nomumwe mita. Below isu anokuisai tafura mutengo vakawanda dzakasiyana wetsvimbo.

Chii chinobatanidzwa mu mari A3 rebar

The pamusoro ndivo anofungidzirwa mitengo kuti caskets A3 kabhoni simbi. Mune zvimwe zviitiko, mari anogona kuva akasiyana. Mutengo kunobva vharuvhu A3 ari kukurukura nyaya zvinhu zvinotevera:

• Stamps inoshandiswa kugadzira simbi. Fittings akaita kuderedzwa chiwanikwa simbi iri zvigadzirwa anodhura kubva st.3ps uye st.3sp. Asi panguva imwecheteyo zvakasiyana, uye nani kuita.

• The dhayamita of rebar. Nengano kuderera ari mutengo indekisi maari A3 kunowedzera. Saka nomusi akakumbira zvikuru diameters (semuenzaniso, 12 mm) nguva nenguva kungaitwa kukanganisika. Panyaya iyi mutengo chihuri Chokwadi, simuka.

• okutengesa mwaka. The Fittings kupfuura zvinodhura A3 anomira muchirimo - muna April uye May, kureva apo kuvaka mwaka inotanga. The kunonyanyisa dhisikaundi nokuda chigadzirwa ichi kunogona kuwanikwa muna December.

• Volume kutenga. Kana yairayira imwe pati huru kwazvo Wholesale mabhizimisi, vagadziri uye bhizimisi anogona kuita mutengi mumwe dhisikaundi akanaka. In chitoro armature Chokwadi, zvakawanda zvinodhura.

• nzvimbo ndapa. Vatengesi zvichaita kudhura tani kuti rebar Chokwadi, zvishoma anodhura pane zvakananga kubva mugadziri.

Kuyera Fixtures (pamwe chinjika parameters urefu) zvakawanda zvinodhura kure-gage.

Chii kunotsvaka kana kutenga

Vatengi mishonga aya kutsvaka nawo pakutanga kunzvimbo iri chaiyo. Somuenzaniso, mumwe munhu anoda 12 A3 rebar. Izvi zvinoreva kuti munhu anoda kutenga shanduro A3 tsvimbo dhayamita 12 mm. Products yaakaita chaiwo pakuchengetwa dzemunharaunda ose GOST, uye vanofanira kunzi maererano nemimwe mitemo. In wokutanga nzvimbo inotaurwa tsvimbo dhayamita mu millimeters rakatangwa. Next kunoratidza chaiko chigadzirwa kirasi (mu iyi A3). Ipapo akaisa pasi vharuvhu nhamba iri dzakawanda kupatsanura (A400 nokuda kabhoni simbi uye kuderedzwa chiwanikwa nokuda A500). Uye ndicho chinhu chokupedzisira zvinoratidzwa GOST, maererano izvo armature (5781-82) rakanyorwa.

Somuenzaniso, ndiye 12 mm dhayamita tsvimbo pasi yakapambadzirwa simbi chichange segwapa sezvinotevera: A 12-III (A500) GOST5781-82. Maererano nemitemo, hapana humwe tsamba uye nhamba kupenda A3 rebar hakufaniri.

Chiizve ndewe achiziva

Kwokupedzisira mutengo yakatengwa Fittings vari dzimwe nguva inobvawo pane kukosha kwebasa Provider yakawedzerwa mabasa. Izvi zvingava Somuenzaniso:

• Kucheka Fittings akapa mu Coils pamusoro matanda achida saizi;

• chokuendesa yakatengwa zvigadzirwa.

batch huru rebar wakatengesa, sezvinoita mutemo, anogona kutumwa chero munharaunda nyika. Melkooptovye vanowatengesa kuita hurukuro maererano chaiyo guta kana nharaunda.

Kana iwe kutenga acho, pakati pezvimwe zvinhu, kubvunza mutengesi gwaro. A3 chisimbiso vanofanira unhu chaizvo unoenderana zvinodiwa GOST.

waivako nokurondedzerwa

A3 rebar kukurumbira pakati vavaki anongofunga nokuti kuti kushandiswa kwayo zvinoita kuvaka kupfuura nesimba uye hunogara kongiri ezvirevo. Kuwedzera tsvimbo A3, indasitiri ano unobereka musimboti A1. yechigarire ichi ane corrugations. Somugumisiro, ukuru adhesion kuti kongiri pazasi. A3 uye A1 chisimbiso kakawanda kushandiswa pakuvaka akasiyana siyana yanyatsosimba kongiri hurongwa. In shanduro iri A1 iri yemanyorero kushandiswa pakuvaka dzakasiyana-siyana ebetsero nhengo, uye A3 - akatakudza. Somuenzaniso, ndiko ekupedzisira kuzvipedza anofanira kushandiswa kana kudira nheyo muzvivako. Kuwedzera yakakwirira mwero adhesion kuti kongiri kuti chisimbiso A3 ane dzimwe zvakwaibatsira.

1. Sezvo kirisendi uye transverse micheto pematanda regai piringisha, mashoko dzakakwirira simba uye ductility kunyange zvakasiyana.

2. Vakavhiyiwa mavharuvhu A3, hunhu vari mukuru, unogona mune chero ezvinhu. tsvimbo Izvi hazvirevi kurasikirwa simba raro kunyange panguva tembiricha kuti -55 inegumi.

3. Option A3 shamhu kabhoni simbi hunogona kungoparara welded. Zvadai zvinokwanisika kubatanidza matanda akadaro A3 uye vakaderera chiwanikwa simbi.

GOST zvinodiwa

In anogadzira zvinhu A3 rebar fanira zvinodiwa GOST zvinotevera zvinofanira kuitwa:

• The curvature pakati pematanda havafaniri kupfuudza 0,6% of chakayerwa urefu.

• Pamusoro pemvura pematanda mbabvu vanofanira kuva makatsemuka, nhapwa rinopfungaira kana kuvira kwezuva.

• Nokuti kugadzirwa wetsvimbo kushandiswa kabhoni simbi chaienzanirana GOST mitemo 380. The raida zvinoitwa pasi chiwanikwa simbi takatsunga kubva chinokosha pamatafura.

Nokuti simbi tsvimbo A400 25G2S akabvumira kwokuderera tensile simba 560 MPa.

Kurongedza tsvimbo maererano GOST

Murayiro nzira iyi zvakare nokudzorwa GOST. A3 Fittings rakazara achiita zvaidiwa mirayiro iyi:

• vakawanda shwashwa chisimbiso tsvimbo havafaniri kupfuudza 15 M;

• sunga mwanda chete waya kana waya tsvimbo;

• pamusoro chikumbiro nembariro zvinogona mumapepa mwanda 3 M kana 5 m;

• mumwe chiputu zvinofanira vasungirirwe Chikwata inotaridza kirasi A3.

senga mitemo

A3 inogona zvifambiswe Fittings zvose mugwagwa uye njanji. Kana vachizvitakudza uye vachidzikisa kunodiwa kuona kuti zvigadzirwa havana nechikonzero chero akaremara kana kuparadzwa.

Tuvana vharafu A3 mu dzokuchengetera kwomuzvarirwo kana kuderedzwa mwando. Zviunganidzirei zvakananga pasi hakubvumidzwi mirayiro. Fittings zvinofanira kuchengetwa packs it pamusoro emapuranga pallets kana echiShinto. Kana achiisa vanofanira kuona kuti hapana zvinhu hakurevi sag.
