Armature 12. Construction Fittings: kugadzirwa, uremu, mutengo

Armature inonzi simbi chigadzirwa vane chimiro tsvimbo refu ine tenderera chikamu. Chinangwa chikuru ichi mhando refu simbi iri kuvandudza kunaka chesamende hurongwa. Kune mhando dzakawanda chisimbiso, rimwe nerimwe yakaitwa zvichinyatso enderana pamwe GOST mitemo.

sarudzo

Concrete - pfuma zvikuru vafuke compression. Dzakaumbwa nepurani yake anogona zvachose pasina kukuvadza kutsungirira kukuru uremu. Zvisinei, zvinosuruvarisa kuti tensile acho pfava chaizvo, saizvozvo sezvinoitwa vachikotama. Nemhaka iyi chikamu pakuvaka zvivako kongiri uye ezvirevo zvinogona kuitika matambudziko akawanda.. Cracking bhesimendi masvingo uye matambudziko muchirimo masimba kuzvimba, kudzikisirana kuti bindepinde nokuda kukwirira wehunyambiri mutoro, etc. The tensile simba nekongiri ndiyo chete 10-15 % of compressive simba.

dambudziko iri, uye nokupa kugadzirisa simbi Fittings. Coefficient pakati chafariz pakuwedzera esimbi pedyo chesamende chakarurama. Izvi zvinoita kuti tikwanise kushandisa zvinhu zviri kunzwisisa. The vakawanda kudiwa mu yakaderera-vosimba chivako chinhu chakakodzera 12 mm mu dhayamita. Concrete zvakagadzirwa, akakomberedzwa ukama mapuranga kwazviri, vanoonekwa nesimba mukuru compressive uye nokudaro - zvinogamuchirika tensile.

With pakuvaka nheyo, izvo chikonzero mutoro panguva kuchitubu pakazvimba, shandisa Fittings - fanira ezvinhu. Kazhinji ichi mhando simbi inoshandiswa uye kuvakwa kwamasvingo (nokusimbaradza masonry, yokumusoro bhandi Rigidity). Chisimbiso muchimiro pajira riya kushandiswa apo achidira mapuriro uye screeds. Uye kuzvishandisa muupenyu kugadzirwa nekongiri makwara, pavings uye zvichingodaro. D. With kuvakwa multi-storey nezvivakwa uye dzimba dambudziko nevhu riri kupfuura inowanzoshandiswa mavharuvhu 16 mm kana kupfuura gobvu.

Pakati pezvimwe zvinhu, nesimbi imwe mhando iyi uye anovandudza nechiidzo dzakadai kuneta simba kongiri, uyewo kuramba zvokuimba kunetseka zvivako panze.

zvinhu

Sezvo Fittings - rinokosha chaizvo chedziviriro yanyatsosimba kongiri kuvaka zvivako, yayo unhu chaihwo zvinodiwa. The mbishi mashoko pagadzirwe kwakadai simbi ane anokosha anowedzera simbi. Kuti uvandudze zvemaziso ehupfumi riri doped pamwe manganese nesilicon. Kuti chakakodzera hwesimba chinokosha unoitwa titanium uye chromium kurapwa.

Mhando mu dhayamita

Kuvaka chisimbiso kungashandiswa nedzimwe ukobvu. Panyaya iyi, pane zvimwe zvinodiwa wakasiyiwa nemirayiro SNIP. Saka, Somuenzaniso, nokuti nheyo zvezvivako nechiedza chaizvo nacho-ne nhoo madziro chakavakwa pamusoro kugadzikana pasi kunogona kushandiswa mune mazariro 10 mm dhayamita. Paivakwa private dzimba Munenge mamwe marudzi ose, sezvo kare ambotaurwa, rinoshandiswa mavharuvhu 12 mm.

Species maererano nzira mukugadzira

Kugadzirwa 12 mm rebar (simbi), uyewo mamwe matanda ukobvu, ane ruzivo zvikuru zviviri:

• By inopisa tikaisa kuti simbi. zvigadzirwa yakadaro inonzi tsvimbo.
• Nokuswedera simbi chando. Izvi anonzi waya ngaaone.

ZvaAtemisi armature 12 mm - kwacho hakusi chakaoma, asi kunoda kushandiswa dzinokosha michina uye zvinonyatsochengeta zvaidiwa dzaivunganidzirwa rwokugadzira.

Wakagadzirira akaita mapuranga uye pajira riya panguva unyanzvi mabhizimisi. Zvinofanira gadzira yavo inosanganisira zvinotevera mumatanho:

• Kana mashoko acho ari kusvitsa mu mabhanzi, akaita unwinding.
• Akaita kuswatura waya kana tsvimbo.
• Chisimbiso unotemwa kune achida urefu. Izvi uye yapfuura akavhiyiwa anoteererwa nemazvo pamusoro chaiyo okurwadzisa michina.
• Izvi zvinoteverwa paungano pamatanda zvinhu kana afoot. oparesheni ichi rinoitwa musi chaiwo nomoto michina. Mune zvimwe zviitiko okunze chokuita pachishandiswa bhuku nomoto.

Dzimwe nguva muedzo nembariro uye meshes anogadzirwa uye zvakananga kuvakwa kwezvivako (kazhinji yakaderera-vosimba). Panyaya iyi, kuti mamiriro anogona welded kana waya. nzira yokutanga ndiyo shoma rakaoma. Kana chechipiri puranga riri kupfuura yakasimba. Chokwadi ndechokuti mumunda Welding simbi rusts nokukurumidza pashure.

pamusoro mhando

On hwaro ichi kusiyanisa maviri chete mhando 12 mm mavharuvhu:

• Smooth, ari kwakajairika tsvimbo kana kumativi muchinjikwa-chikamu waya.
• Corrugated. Pamusoro pemvura iri vharafu kwakadaro ndiko transverse (kazhinji kirisendi) uye mbabvu longitudinal. zvakagadzirwa kwakadaro kunoita kuti awedzere adhesiveness pamwe chesamende puranga nhengo.

Mhando kushanda ezvinhu

The mapuranga dzinowanzoshandiswa zvinotevera marudzi Fittings:

• kugova;
• Kushanda (chaizvoizvo 12 mm matanda);
• gungano;
• uketani.

Pasi mashoko kushanda mavharuvhu 12 mm rakakamurwa:

• Epfungwa. Kushandiswa kana zvakakodzera inokosha mukurumari nekongiri hurongwa (mu kwenyika-asingatani nzvimbo, mukuru-kuwedzera zvivako kumusoro, muna pachena wehunyambiri mutoro zambuko uye t.).
• Free kuti makakatanwa. Ukapisa murwi pasina prestressing. It yakashandiswa kwakajairika kongiri hurongwa.

Weight armature 12 mm

Pakuvaka vashomanana private zvivako simbi zvaida Kazhinji inofungidzirwa kumhanya mamita. Manufacturers kazhinji tengesa rebar uremu. Izvi zvingaita kuti vamwe matambudziko ari Masvomhu. Kuti uzive kuti makirogiramu akawanda chisimbiso kunodikanwa imwe nyaya, zvinokosha kuti vawande kurema chete mita rimwe zvaida zvinhu pakureba. Wokutanga zvinoriumba kunoenderana mhando chisimbiso uye kunorondedzerwa chaiwo pamatafura.

Saka armature 12 mm uremu (anobudiswa zvinoenderana GOST) ndiyo 0.89 makirogiramu / achimhanya mita. Toti uchida kuhaya 25 M nokuda pakuvaka imba. Somugumisiro, vaparidzi kutenga 25 X 0.89 = 22.25 makirogiramu tsvimbo.

Chokuguma uye mari Fittings

Smooth simbi 12 mm tsamba A1, fluted pasina punching - A3. Uyewo, kupenda anogona kuwanikwa armature kugadzira nzira (A - goryachekatnaya, B - akaita chando muitiro) uye akashandisa simbi chitambi (digits). Rinonunurwa chigadzirwa angabvuma mu Coils kana mbariro. Somuenzaniso, rokuti chisimbiso "A3 A500S" iri zvichishandurwa sezvinotevera:

• zvinhu ane chemarata pamusoro (A3),
• kugadzirwa nezvinhu inopisa rinopfungaira (A),
• simbi mugwaro - 3PS (A500S)

Mutengo ichi mhando nesimbi kunobva zvikurukuru pamusoro ukobvu wayo uyewo chiratidzo. How zvikuru hungada mavharuvhu 12? Mutengo dhayamita tsvimbo dzakadaro - goryachekatnye (kupfuura mukurumbira chimiro) - kubva bhizimisi akasiyana iri kuwanda vanenge zviuru 22-29 rubles por tani .. Chokwadi, kana kutenga chaaizokumbira mutengesi gwaro zvaidiwa GOST. Achinyora vharuvhu yemanyorero Zviine kunyange panguva tikaisa. Kana kugadzirwa tsvimbo namazariro izvi hazvina kuitwa, avo kumigumo anozivikanwa ne zvisingafi neingi. Saka, Somuenzaniso, simbi A500S kunoratidzwa ne chena uye zvitema, A600S - yellow uye chena, uye saka kuwana chaiyo kumirisana nevamwe mhando tsvimbo kunogona kuva anokosha matafura ...

Nokudaro, Fittings - rimwe zvikuru nevanhu pamusoro pamusika, mhando nesimbi - inogona kugadzirwa nenzira dzakasiyana akasiyana mamakisi hwendarira, vane kumeso kana grooved pamusoro, kuva mukobvu kana mutete. 12 mm tsvimbo ndezvimwe zvezvisarudzo dzakakurumbira mhando. Kana kutenga, uyewo pakuunganidza zvimwe chisimbiso, tinofanira kutanga teerera kupenda uye pamusoro mhando.
