Simbi chimiro chimiro chinoumbwa nezvinhu zvesimbi, inova imwe yemhando huru yekuvaka chivako.Chimiro chacho chinonyanya kuumbwa nematanda esimbi, mbiru dzesimbi, trusses dzesimbi uye zvimwe zvikamu zvakagadzirwa nechikamu chesimbi uye mahwendefa esimbi, uye inotora silanization, pure manganese phosphating, kugeza nekuomesa, galvanizing uye zvimwe kubvisa ngura uye antirust maitiro. anowanzobatanidzwa ne welds, mabhoti kana rivets.Nekuda kwehuremu hwayo uye nyore kuvakwa, inoshandiswa zvakanyanya mumafekitari makuru, nzvimbo, super high-rise uye mamwe minda.Steel structure iri nyore kuita ngura, general steel structure kusvika ngura, galvanized kana pendi, uye kugadzirisa nguva dzose.
Simbi inoratidzwa nekusimba kwepamusoro, huremu huremu, kunaka kwese kuoma, kuramba kwakasimba kune deformation, saka inonyanya kukodzera kuvakwa kwenzvimbo hombe uye yepamusoro-soro, zvivakwa zvinorema zvakanyanya; Izvo zvinhu zvine homogeneity yakanaka uye isotropy uye yakanaka elastomer. , iyo inonyanya kuenderana nemafungiro ekutanga einjiniya mechanics. The zvinhu zvine plasticity yakanaka uye kuoma, inogona kuva nedeformation yakakura, uye inogona kutakura mutoro wesimba zvakanaka.Nguva pfupi yekuvaka;Nehupamhi hwemaindasitiri, kugadzirwa kwakasarudzika nepamusoro. degree of mechanization inogona kuitwa.
Simbi ine simba repamusoro inofanira kudzidzwa kuti ivandudze goho resimba resimbi chimiro. Pamusoro pezvo, mhando itsva dzesimbi dzinofanira kukungurutswa, senge H-beam (inozivikanwawo sesimbi yakafara flange) uye T-yakaita simbi uye profiled simbi ndiro kusangana nezvinodiwa zvehombe span zvivakwa uye super refu zvivakwa.
Uye zvakare, hapana kupisa bhiriji mwenje simbi yekugadzira sisitimu, chivakwa pachacho hachisi chekuchengetedza simba, iyi tekinoroji ine hungwaru hwekubatanidza zvidimbu kugadzirisa dambudziko rebhiriji rinopisa uye rinotonhora; Iyo diki truss chimiro inobvumira tambo uye epamusoro nepasi pemvura pombi. kuti ipfuure nepamadziro, zviri nyore pakuvaka nekushongedza.
Hunhu hwesimbi chimiro
1, simba rezvinhu rakakwirira, uremu hwaro hwakareruka
Simbi ine simba rakakwirira uye elastic modulus.Kuenzaniswa nekongiri uye huni, chiyero chehuwandu hwayo uye kusimba kwegoho yakaderera, saka pasi pemamiriro akafanana ekushushikana, chikamu chesimbi chimiro chenhengo iduku, kureruka, nyore kutakura uye kuisa, inokodzera kureba kukuru, kureba kwepamusoro, kubereka chimiro.
2, kuoma kwesimbi, kunaka kwepurasitiki, kufanana kwezvinhu, kuvimbika kwechimiro chepamusoro
Inokodzera kutakura maitiro uye simba rinoshandiswa, rine maitiro akanaka ekudengenyeka.Chimiro chemukati chesimbi chakafanana, pedyo ne isotropic homogenous body.Iyo chaiyo yekushanda kwekugadzirwa kwesimbi inopindirana nedzidziso yekuverenga.Saka chimiro chesimbi chine kuvimbika kwakanyanya.
3. Kugadzirwa uye kuiswa kwesimbi yakagadzirwa zvakanyanya
Steel structure nhengo dziri nyore kugadzira mufekitori uye dzinoungana panzvimbo.Ifekitari yekugadzira michina yekugadzirwa kwesimbi ine zvakanakira zvehupamhi hwepamusoro, hukuru hwekugadzira hunyanzvi, kukurumidza kwegungano renzvimbo uye nguva pfupi yekuvaka.Steel chimiro chimwe chezvakanyanya kugadzirwa. zvimiro.
4, simbi chimiro chekuisa chisimbiso kuita kwakanaka
Nekuti iyo yakashongedzwa chimiro inogona kuvharwa zvachose, inogona kugadzirwa mumitsipa yakakwira ine mhepo yakanaka uye kusungirirwa kwemvura, madziva makuru emafuta, mapaipi ekumanikidza uye zvichingodaro.
5. Simbi yakagadzirwa inodzivirira kupisa uye haidziviriri moto
Kana tembiricha iri pasi pe150℃, zvinhu zvesimbi zvinoshanduka zvishoma.Naizvozvo, chimiro chesimbi chakakodzera kumusangano unopisa, asi pamusoro pechigadziro neanenge 150 madhigirii ekupisa kwemwaranzi, kuchengetedzwa nebhodhi rekudzivirira kupisa.Tembiricha iri pakati pe300.℃uye 400℃.Simbi yesimbi uye elastic modulus inoderera zvakanyanya, uye simba resimbi rinoita zero kana tembiricha inosvika 600.℃.Muzvivakwa zvine zvinodiwa zvekudzivirira moto, zvivakwa zvesimbi zvinofanirwa kuchengetedzwa nezvinhu zvinoramba kuti zvivandudze chiyero chekudzivirira moto.
6, simbi chimiro ngura kuramba kwakashata
Kunyanya munharaunda yezvinonyorova uye zvinoparadza media, zviri nyore kuita ngura.General simbi chimiro kuita ngura, galvanized kana pendi, uye kugadzirisa nguva dzose.Matanho akakosha akadai se "zinc block anode protection" anofanira kutorwa kudzivirira kukoromoka kweoffshore platform structures mvura yegungwa.
7, yakaderera kabhoni, kuchengetedza simba, girini kuchengetedza kwezvakatipoteredza, inogona kushandiswa zvakare
Kuputswa kwezvivakwa zvesimbi kunoburitsa anenge asina marara ekuvaka uye simbi inogona kushandiswazve.
