Mhando uye tsanangudzo dzesimbi

I. Steel Plate uye Strip
Simbi ndirorakakamurwa kuita gobvu simbi ndiro, nhete simbi ndiro uye flat simbi, mataurirwo ayo ane chiratidzo "a" uye upamhi x ukobvu x kureba mumamirimita. Zvakadai se: 300x10x3000 iyo yakafara 300mm, ukobvu hwe10mm, kureba kwe3000mm simbi ndiro.

Gobvu simbi ndiro: ukobvu mukuru kupfuura 4mm, upamhi 600 ~ 3000mm, kureba 4 ~ 12m.
Mutete simbi ndiro: ukobvu isingasviki 4mm, upamhi 500 ~ 1500mm, kureba 0.5 ~ 4m.
Simbi yakatsetseka:ukobvu 4 ~ 60mm, hupamhi 12 ~ 200mm, kureba 3 ~ 9m.
Simbi mahwendefa uye mitsetse yakakamurwa zvichienderana nenzira yekukunguruka:inotonhora yakakungurutswa ndirouyemahwendefa anopisa akakungurutswa; maererano nekukora: mahwendefa esimbi matete (pazasi pe4mm), mahwendefa esimbi akakora (4-60mm), mamwe mahwendefa akakora (pamusoro pe60mm)

2. simbi inopisa
2.1I-danda
I-beam simbi sezvinoreva zita rayo, ndeyeI-yakaita muchinjiko-chikamu maprofiles, ekumusoro neakadzika maflange ari flush.
I-beam simbi yakakamurwa kuva zvakajairika, chiedza uye bapiro upamhi hwemarudzi matatu, ane chiratidzo "basa" uye nhamba akati. Ndeipi nhamba inomiririra hurefu hwechikamu chenhamba yemasentimita. 20 uye 32 pamusoro peiyo yakajairwa I-beam, nhamba imwechete uye yakakamurwa kuita a, b uye a, b, c rudzi, webhu ukobvu uye hupamhi hweflange zvakateerana kuwedzera 2mm. akadai T36a kuti mhiri-chikamu kureba 360 mm, dandemutande ukobvu yekirasi yakajairika I-beam. I-matanda anofanira kuedza kushandisa thinnest web thickening yemhando a, iyo inokonzerwa nehuremu hwayo, asi nguva yemuchinjikwa-chikamu cheinertia yakakura.
Iyo nguva ye inertia uye radius ye gyration yeI-matanda muhupamhi nzira idiki zvakanyanya pane idzo dziri munzira yehurefu. Nekudaro, pane zvimwe zvipimo mukushandisa, kazhinji zvakakodzera kune imwe-nzira yekukotama nhengo.
3.channel simbi
Simbi yechiteshi yakakamurwa kuita marudzi maviri eyakajairwa chiteshi simbi uye lightweight chiteshi simbi. Chiteshi chesimbi chine chiratidzo """ uye nhamba yakataurwa. Zvimwechete neI-beam, nhamba yemasendimita inomiririrawo kureba kwechikamu chemuchinjikwa. Zvakadai se [20 neQ [20] zvichiteerana, pachinzvimbo chechikamu chekukwirira kwe200mm yesimbi yakajairwa simbi uye light channel steel. I-danda.

 

4. angle simbi
Angle simbi yakakamurwa kuva marudzi maviri equilateral angle simbi uye isina kuenzana kona simbi.
Equilateral angle: yayo yakaenzana perpendicular makumbo maviri akaenzana kureba, modhi yayo ine chiratidzo “L” uye upamhi hwemakumbo x makumbo ukobvu mumamilimita, seL100x10 pahupamhi hwemakumbo 100mm, ukobvu hwemakumbo kuita 10mm equilateral angle.
Makona asina kuenzana: ayo akaenzana perpendicular makumbo maviri haana kuenzana, muenzaniso une chiratidzo "" uye urefu hwemakumbo hupamhi x hupamhi hwemakumbo x hupamhi hwemakumbo mumamilimita, zvakadai seL100x80x8 yehupamhi hwemakumbo marefu 100mm, hupamhi hwemakumbo mapfupi 80mm, kukora kwemakumbo kwe8mm kusaenzana.

 
5. H-danda(yakakungurutswa uye yakasungwa)
H-danda rakasiyana neI-beam.
(1) yakafara flange, saka kwave nehupamhi flange I-beam yakataurwa.
(2) Nzvimbo yemukati yeflange haifaniri kuva nemateru, nzvimbo dzepamusoro nepamusoro dzakafanana.
(3) kubva kumhando yekugovera zvinhu, I-beam cross-section yezvinyorwa zvinonyanya kuiswa muwebhu zvakatenderedza, zvakanyanya kune mativi ekuwedzera, iyo shoma simbi, uye yakakungurutswa H-beam, kugovera zvinhu kunotarisa kumucheto kwechikamu.
Nekuda kweizvi, H-beam cross-section maitiro ari pachena akakwirira kune echinyakare basa, chiteshi, kona uye kusanganiswa kwavo kwechikamu-chikamu, kushandiswa kwehupfumi mhedzisiro.
Zvinoenderana neazvino mureza wenyika "hot rolled H-beam uye chikamu T-beam" (GB/T11263-2005), H-beam yakakamurwa muzvikamu zvina, izvo zvakasarudzwa sezvizvi: wide flange H-beam - HW (W for Wide English prefix), tsanangudzo kubva ku100mmx100mm ~ 400mmx40; pakati flange H-beam - HM (M for Middle English prefix), tsanangudzo kubva Specification kubva 150mmX100mm~600mmX300mm: Narrow Cui-kumucheto H-beam - HN (N for Narrow English prefix); mutete-madziro H-beam - HT (T for Thin English prefix). H-beam specification marking inoshandiswa: H uye kukosha kwehurefu hweh value x hupamhi hweb value x kukosha kwehutengo hwewebhu t kukosha x kukosha kwehuwandu hweflange t2 kukosha kwakataurwa. Zvakadai seH800x300x14x26, kureva, kureba kwechikamu che800mm, flange yakafara 300mm, dandemutande gobvu 14mm, flange ukobvu hwe26mm H-beam. Kana kuratidzwa pekutanga nezviratidzo HWHM uye HN akati H-beam chikamu, achiteverwa "urefu (mm) x upamhi (mm)", akadai HW300x300, kureva, chikamu urefu 300mm, flange upamhi hwe300mm yakafara flange H-danda.
6. T-danda
Sectional T-beam (Figure) yakakamurwa muzvikamu zvitatu, iyo code ndeyotevera: yakafara flange chikamu cheT-beam - TW (W for Wide English head); muchikamu cheflange cheT-beam - TM (M yeMiddle English musoro); nhete flange chikamu cheT-beam - TN (N yeNarrow English head). Sectional T-beam neinowirirana H-danda pamwe nepakati pewebhu yakaenzana yakapatsanurwa kuita. Sectional T-beam zvakatemwa ne: T uye kureba h kukosha x upamhi b kukosha x web ukobvu t kukosha x flange ukobvu t kukosha. Zvakadai seT248x199x9x14, kureva, kureba kwechikamu che248mm, hupamhi hwebapiro 199mm, kukora kwewebhu 9mm, flange ukobvu hwe14mm T-beam. Inogonawo kushandiswa neH-beam yakafanana inomiririra, yakadai seTN225x200 kureva, chikamu chekukwirira kwe225mm, flange yakafara ye200mm yakamanikana flange chikamu T-beam.

7.structural simbi pombi
Simbi pombi sechikamu chakakosha chesimbi nesimbi zvigadzirwa, nekuda kwekugadzira kwayo maitiro uye chimiro chepombi inoshandiswa mune zvakasiyana zvakaipa uye yakakamurwa kuita.pombi yesimbi isina musono(kutenderera kwakashata) uyewelded simbi pombi(ndiro, ine zvakaipa) mapoka maviri, ona Mufananidzo.
Simbi chimiro chinowanzo shandiswa mukupisa-yakakungurutswa isina musono pombi uye welded simbi pombi, welded simbi pombi akakungurutswa uye welded kubva simbi tambo, maererano nehukuru hwepombi dhayamita, uye rakakamurwa kuva marudzi akatwasuka musono welding uye spiral welding.LSAW simbi pombimataurirwo ekunze kwedhayamita ye32 ~ 152mm, kukobvu kwemadziro kwe20 ~ 5.5mm. nyika mitemo ye "LSAW simbi pombi" (GB/T13793-2008). Mushonga wesimbi isina musono pombi zvinoenderana nerudzi rwepasirese "structural seamless simbi pombi" (GB/T8162-2008), kune marudzi maviri ekupisa-akakungurutswa uye anotonhora-anodhonzwa, inotonhora-inodhonzwa pombi inogumira kudiki pombi dhayamita, inopisa-yakakungurutswa seamless simbi pombi yekunze dhayamita ye32 ~ 630mm, madziro makubvu e25mm ~ 75mm.
Zvinotsanangurwa kunze kwedhayamita x madziro ukobvu (mm), senge φ102x5. Welded simbi pombi yakakotama uye welded nesimbi strip, mutengo wakaderera. Simbi pombi cross-section symmetry ziso nharaunda kugovera zvine musoro, nguva ye inertia kumativi ese uye radius ye gyration yakafanana uye yakakura, saka kuita kwesimba, kunyanya kana axial pressure iri nani, uye chimiro chayo checurve inoita kuti isanyanya kupikisa mhepo, mafungu, ice, asi mutengo unodhura uye chimiro chekubatanidza chinowanzo kuoma.
