Maplate esimbi nemachira anorongwa zvichienderana nenzira yekumonera:ndiro dzakamonerwa dzinotonhorauyendiro dzinopisa dzakamonerwa; zvichienderana neukobvu: mapurati esimbi matete (ari pasi pe4mm), mapurati esimbi makobvu (4-60mm), mapurati akobvu zvakanyanya (ari pamusoro pe60mm)

2. simbi inoputirwa inopisa
2.1I-danda
Simbi yesimbi inonzi I-beam, sekureva kwezita rayo, ine chimiro cheI-shaped cross-section profiles, flanges dzepamusoro nedzepasi dzakapfava.
Simbi yeI-beam yakakamurwa kuita upamhi hwemhando nhatu, hwakareruka uye hwemapapiro, ine chiratidzo chekuti "basa" uye nhamba yeakati. Nhamba ipi inomiririra kureba kwechikamu chenhamba yemasendimita. 20 ne32 pamusoro peI-beam yakajairika, nhamba imwechete uye yakakamurwa kuita a, b uye a, b, c, ukobvu hwayo hwewebhu uye upamhi hweflange zvinokwira ne2mm. senge T36a kuti kureba kwechikamu che360 mm, ukobvu hwewebhu hwekirasi yeI-beam yakajairika. I-beams dzinofanira kuedza kushandisa ukobvu hwewebhu hwakatetepa hwerudzi a, hunokonzerwa nehuremu hwayo hwakareruka, nepo nguva yechikamu chechikamu cheinertia yakakura.
Nguva yekusashanda zvakanaka uye radius yekukwira kweI-beams munzira yakafara idiki zvikuru pane iri munzira yekukwirira. Saka, kune zvimwe zvipingamupinyi mukushandiswa, zvinowanzo shandiswa kune nhengo dzinokotama dzine nzira imwe chete.
3.simbi yechiteshi
Simbi yechiteshi yakakamurwa kuita mhando mbiri dzesimbi yechiteshi yakajairika nesimbi yechiteshi yakareruka. Rudzi rwesimbi yechiteshi ine chiratidzo “[””] uye nhamba yezvakataurwa. Zvakafanana neI-beam, nhamba yemasendimita inomiririrawo kukwirira kwechikamu chemuchinjikwa. Zvakadai se [20 na Q [20 zvichiteerana, panzvimbo yekukwirira kwechikamu che200mm chesimbi yechiteshi yakajairika nesimbi yechiteshi yakareruka. 14 uye simbi yechiteshi yakajairika inopfuura 24, nhamba imwechete ye sub-a, b uye a, b, c, zvinoreva zvakafanana neI-beam.

 

4. simbi yekona
Simbi yeAngle yakakamurwa kuita mhando mbiri dzesimbi yeangle yakaenzana uye simbi yeangle isina kuenzana.
Kona yakaenzana: makumbo ayo maviri akaenzana akaenzana, modhi yayo ine chiratidzo chekuti "L" uye upamhi hwemakumbo x ukobvu hwemakumbo mumamilimita, senge L100x10 yehupamhi hwemakumbo e100mm, ukobvu hwemakumbo e10mm ekona yakaenzana.
Makona asina kuenzana: makumbo ayo maviri akatarisana haana kuenzana, modhi ine chiratidzo chekuti "" uye upamhi hwemakumbo marefu x upamhi hwemakumbo mapfupi x ukobvu hwemakumbo mumamilimita, senge L100x80x8 yehupamhi hwemakumbo marefu hwe100mm, upamhi hwemakumbo mapfupi hwe80mm, ukobvu hwemakumbo hwe8mm angle isina kuenzana.

 
5. H-danda(yakamonerwa uye yakasungirirwa)
H-beam yakasiyana neI-beam.
(1) flange yakafara, saka kwave neflange yakafara I-beam yakadaro.
(2) Nzvimbo yemukati yeflange haidi kuva nekwakatsetseka, nzvimbo dzepamusoro nedzepasi dzakafanana.
(3) kubva muchimiro chekugoverwa kwezvinhu, chikamu cheI-beam chechinhu chacho chinonyanya kuunganidzwa muwebhu yakatenderedza, simbi yakawanda kumativi ekuwedzera, simbi shoma, uye H-beam yakakungurutswa, kugoverwa kwezvinhu kunotarisa kumucheto kwechikamu.
Nekuda kweizvi, hunhu hwechikamu cheH-beam huri nani pane basa rechinyakare, mugero, kona uye musanganiswa wazvo wechikamu chepakati, kushandiswa kwemhedzisiro iri nani yehupfumi.
Zvichienderana nemutemo wenyika we "hot rolled H-beam nechikamu cheT-beam" (GB/T11263-2005), H-beam yakakamurwa kuita zvikamu zvina, izvo zvakarongwa seizvi: wide flange H-beam - HW (W yeWide English prefix), specifications kubva pa100mmx100mm ~ 400mmx400mm; middle flange H-beam - HM (M yeMiddle English prefix), specifications kubva paSpecification kubva pa150mmX100mm~600mmX300mm: Narrow Cui-edge H-beam - HN (N yeNarrow English prefix); thin-walled H-beam - HT (T yeThin English prefix). H-beam specification marking inoshandiswa: H uye kukosha kwehurefu hwe h kukosha x upamhi hwe b kukosha x kukosha kwehukobvu hwe web t kukosha x kukosha kwehukobvu hwe flange t kukosha kwataurwa. Zvakadai seH800x300x14x26, kureva kuti, pakukwirira kwechikamu che800mm, upamhi hweflange hwe300mm, ukobvu hwewebhu hwe14mm, ukobvu hweflange hwe26mm H-beam. Kana kuti kutanga wakaratidzwa nezviratidzo zveHWHM uye HN zvakati H-beam category, zvichiteverwa ne "kukwirira (mm) x upamhi (mm)", zvakaita seHW300x300, kureva kuti, kukwirira kwechikamu che300mm, upamhi hweflange hwe300mm H-beam hwakafara.
6. T-danda
Chikamu cheT-beam (Mufananidzo) chakakamurwa muzvikamu zvitatu, kodhi yacho ndeiyi inotevera: chikamu cheflange chakafara cheT-beam - TW (W yemusoro weWide English); muchikamu cheflange cheT-beam - TM (M yemusoro weMiddle English); chikamu cheflange chakamanikana cheT-beam - TN (N yemusoro weNarrow English). Chikamu cheT-beam neH-beam inoenderana nepakati pewebhu zvakaenzana zvakakamurwa kuita. Zvimiro zveT-beam zvechikamu zvakanyorwa ne: T uye kukwirira h kukosha x upamhi b kukosha x ukobvu hwewebhu t kukosha x ukobvu hweflange t kukosha. Zvakadai seT248x199x9x14, kureva kuti, pakukwirira kwechikamu che248mm, upamhi hwemapapiro hwe199mm, ukobvu hwewebhu hwe9mm, ukobvu hweflange hwe14mm T-beam. Inogona zvakare kushandiswa neH-beam yakafanana, senge TN225x200, kureva kuti, kureba kwechikamu che225mm, upamhi hweflange ye200mm yakamanikana flange chikamu cheT-beam.

7. pombi yesimbi yezvivakwa
Pombi yesimbi sechikamu chakakosha chezvigadzirwa zvesimbi nesimbi, nekuda kwemaitiro ayo ekugadzira uye chimiro chepombi inoshandiswa mumhando dzakasiyana dzesimbi uye yakakamurwa kuita zvikamu zviviri:pombi yesimbi isina musono(yakashata) uyepombi yesimbi yakasungirirwa(ndiro, ine zvakaipa) mapoka maviri, ona Mufananidzo.
Chimiro chesimbi chinowanzoshandiswa mupombi yesimbi isina musono inopfurwa inopisa uye pombi yesimbi yakapfurwa, pombi yesimbi yakapfurwa uye yakapfurwa kubva kumutsara wesimbi, zvichienderana nehukuru hwedhayamita yepombi, uye yakakamurwa kuita mhando mbiri dzekubatanidza musono wakatwasuka uye kubatanidza spiral.Pombi yesimbi yeLSAWzvirevo zvedhayamita yekunze ye32 ~ 152mm, ukobvu hwemadziro hwe20 ~ 5.5mm. zviyero zvenyika zve "LSAW steel pipe" (GB/T13793-2008). Pombi yesimbi isina musono yechivakwa zvichienderana ne "structural seamless steel pipe" yenyika (GB/T8162-2008), kune mhando mbiri dzepombi inoputirwa nekupisa uye inotonhorera, inotonhorera inogumira kudhayamita diki yepombi, pombi yesimbi isina musono yekupisa ine dhayamita yekunze ye32 ~ 630mm, ukobvu hwemadziro hwe25 ~ 75mm.
Magadzirirwo ekunze kwedhayamita x ukobvu hwemadziro (mm), akadai se φ102x5. Pombi yesimbi yakasungirirwa yakakotamiswa uye yakasungirirwa nesimbi, mutengo wacho wakaderera. Kupararira kwenzvimbo yeziso yepombi yesimbi kwakaringana, nguva yekusagadzikana kumativi ese uye radius ye gyration yakafanana uye yakakura, saka mashandiro esimba, kunyanya kana kumanikidzwa kwe axial kuri nani, uye chimiro chayo chekukombama chinoita kuti isanyanya kudziviswa nemhepo, mafungu, chando, asi mutengo wacho unodhura uye chimiro chekubatanidza chinowanzo kuve chakaoma.
