Ndezvipi zvakanakira uye maitiro eH beam?

H beaminoshandiswa zvakanyanya mukugadzirwa kwemazuva ano kwesimbi. Iyo yepamusoro yeH-chikamu simbi haina kurerekera, uye kumusoro uye yakadzika nzvimbo dzakafanana. Chimiro chechikamu cheH - danda chiri nani pane chetsikaIni - beam, chiteshi simbi uye Angle simbi. Saka ndeapi maitiro eH beam?

1. Kusimba kwechimiro chepamusoro

Kuenzaniswa neI-beam, chikamu modulus yakakura, uye kutakura mamiriro akafanana panguva imwe chete, simbi inogona kuponeswa ne10-15%.

2. Flexible uye hupfumi hwekugadzira maitiro

Panyaya yehurefu hwakafanana hwedanda, chimiro chesimbi chakakura 50% pane chimiro chekongiri, zvichiita kuti marongerwo awedzere kushanduka.

3. Chiedza chechimiro chechimiro

Kuenzaniswa nekongiri chimiro, huremu hwechimiro chakareruka, kuderedzwa kwehuremu hwechimiro, kuderedza simba remukati reiyo dhizaini dhizaini, inogona kuita kuti chivakwa chekuvaka hwaro hwekugadzirisa zvinodiwa zvakaderera, kuvaka kuri nyore, mutengo. yakaderedzwa.

4. Kugadzikana kwepamusoro kwemaitiro

Iyo inopisa yakakungurutswa H-beam ndiyo huru yesimbi dhizaini, chimiro chayo ndeyesainzi uye inonzwisisika, yakanaka plasticity uye kuchinjika, yakakwirira structural kugadzikana, yakakodzera kutakura vibration uye kukanganisa mutoro weiyo yakakura chivako chimiro, kugona kwakasimba kurwisa njodzi dzinongoitika dzoga, kunyanya yakakodzera zvimwe zvivakwa munzvimbo dzinodengenyeka. Zvinoenderana nenhamba, munyika yenjodzi yekudengenyeka kwenyika kukuru 7 kana kupfuura, simbi yakaita seH, kunyanya zvivakwa zvesimbi zvakatambura zvishoma.

5. Wedzera nzvimbo inobudirira yekushandiswa kwechimiro

Kuenzaniswa nekongiri yakagadzirwa, simbi yekugadzira mbiru chikamu chikamu chikamu chidiki, chinogona kuwedzera inobudirira kushandiswa nzvimbo yechivako, zvichienderana nemhando dzakasiyana dzechivako, inogona kuwedzera inobudirira kushandiswa nzvimbo ye4-6%.

6. Chengetedza basa uye zvinhu

Kuenzaniswa neWelding H-beam simbi, inogona kuchengetedza zvakanyanya vashandi uye zvinhu, kuderedza kushandiswa kwezvinhu, simba uye basa, kuderera kwasara kushushikana, kutaridzika kwakanaka uye kunaka kwepasi.

7. Zviri nyore kune mechanical processing

Zviri nyore kubatanidza uye kuisa zvimiro, asi zvakare nyore kubvisa uye kushandisa zvakare.

8. Kuchengetedza kwezvakatipoteredza

Kushandiswa kweH-chikamu simbiinogona kunyatsodzivirira zvakatipoteredza, iyo inoratidzwa muzvikamu zvitatu: kutanga, kana ichienzaniswa nekrete, inogona kushandisa chivako chakaoma, zvichiita kuti ruzha rushoma uye guruva shoma; Chechipiri, nekuda kwekuderedza uremu, kuchera ivhu shoma rekuvaka nheyo, kukuvadza kuduku kune zviwanikwa zvevhu, kunze kwekuderedza kukuru kwehuwandu hwekongiri, kuderedza kuwanda kwekuchera dombo, kunobatsira kudzivirira kwezvakatipoteredza; Chechitatu, mushure mehupenyu hwebasa rekuvaka chivako chapera, huwandu hwemarara akasimba anogadzirwa mushure mekunge chigadziro chaputswa idiki, uye kukosha kwekudzokororwa kwezvinhu zvesimbi zvakasara zvakakwirira.

9. Dhigirii yepamusoro yekugadzirwa kwemaindasitiri

Chimiro chesimbi chakavakirwa pakupisa chakakungurutswa H danda chine dhigirii yakakwira yekugadzirwa kwemaindasitiri, iyo yakanakira kugadzira michina, kugadzirwa kwakasimba, kurongeka kwepamusoro, kuisirwa nyore, kuvimbiswa kwemhando nyore, uye inogona kuvakwa mufekitori yekugadzira imba chaiyo, kugadzira mabhiriji. fekitari, fekitori yekugadzira mafekitari, etc. Kuvandudzwa kwechimiro chesimbi kwakagadzira uye kwakafambisa kukura kwemazana emaindasitiri matsva.

10. Kumhanya kwekuvaka kunokurumidza

Diki tsoka, uye yakakodzera kuvakwa kwemamiriro ekunze ese, kukanganiswa kudiki nemamiriro ekunze. Iyo yekumhanyisa yekuvaka yesimbi yakagadzirwa neinopisa yakakungurutswa H danda inenge 2-3 nguva yeiyo kongiri chimiro, capital turnover rate inopetwa kaviri, mari yezvemari inoderedzwa, kuitira kuchengetedza mari. Kutora "Jinmao Tower" muPudong yeShanghai, "chivakwa chakareba kwazvo" muChina semuenzaniso, mutumbi mukuru wechivakwa chine hurefu hunosvika 400m wakapedzwa munguva isingasviki hafu yegore, nepo chimiro chesimbi-kongiri chaida maviri. makore ekupedzisa nguva yekuvaka.
