Iindidi kunye neenkcukacha zentsimbi

I. Steel Plate kunye Strip
Ipleyiti yentsimbiyahlulwe ibe yipleyiti yentsimbi eshinyeneyo, ipleyiti yentsimbi ecekethekileyo kunye nentsimbi ecaba, iinkcukacha zayo ezinophawu “a” kunye nobubanzi x ubukhulu x ubude ngeemilimitha. Njenge: a 300x10x3000 ukuba ububanzi 300mm, ubukhulu 10mm, ubude 3000mm ipleyiti steel.

Ipleyiti yentsimbi eshinyeneyo: ubukhulu obukhulu kune-4mm, ububanzi bungama-600 ~ 3000mm, ubude be-4 ~ 12m.
Ipleyiti yentsimbi ebhityileyo: ubukhulu obungaphantsi kwe-4mm, ububanzi 500 ~ 1500mm, ubude 0.5 ~ 4m.
Intsimbi ecaba: ukutyeba 4 ~ 60mm, ububanzi 12 ~ 200mm, ubude 3 ~ 9m.
Iipleyiti zentsimbi kunye nemicu zihlelwa ngokwendlela yokuqengqeleka:iipleyiti eziqengqelekayo ezibandayokwayeiipleyiti eshushu esongwayo; ngokobukhulu: iipleyiti zentsimbi ezibhityileyo (ngaphantsi kwe-4mm), iipleyiti zentsimbi ezishinyeneyo (4-60mm), iipleyiti ezityebileyo ezongezelelweyo (ngaphezu kwe-60mm)

2. intsimbi eshushu
2.1I-beam
Intsimbi ye-I-beam njengoko igama layo libonisa, i-I-shaped cross-section profiles, i-flanges ephezulu kunye nesezantsi iyagungxula.
Intsimbi ye-I-beam ihlulwe ibe yinto eqhelekileyo, ukukhanya kunye nobubanzi bephiko lweentlobo ezintathu, kunye nesimboli "umsebenzi" kunye nenani elithi. Leliphi inani elimele ubude becandelo lenani leesentimitha. I-20 kunye ne-32 ngaphezu kwe-I-beam eqhelekileyo, inani elifanayo kwaye lahlulwe libe ngu-a, b kunye no-a, b, uhlobo lwe-c, ubukhulu bayo bewebhu kunye nobubanzi be-flange ngokulandelelana ngokunyuka kwe-2mm. ezifana T36a ukuba ukuphakama cross-icandelo 360 mm, ubukhulu web yeklasi eqhelekileyo I-beam. I-I-beams kufuneka izame ukusebenzisa i-thinnest web thickness of type a, ngenxa yobunzima bayo obulula, ngelixa i-cross-section moment of inertia inkulu.
Umzuzu we-inertia kunye ne-radius ye-gyration ye-I-beams kwicala lobubanzi zincinci kakhulu kunezo ezikwindlela yokuphakama. Ke, kukho imida kwisicelo, ifanelekile ngokubanzi kumalungu aguqayo ngendlela enye.
3.intsimbi yomjelo
Intsimbi yomjelo yahlulahlulwe yaba ziindidi ezimbini zentsimbi yentsimbi eqhelekileyo kunye nentsimbi yesitishi esikhaphukhaphu. Uhlobo lwentsimbi yomjelo kunye nesimboli "" kunye nenani elithe. Okufanayo kunye ne-I-beam, inani leesentimitha likwamele ukuphakama kwecandelo elinqamlezayo. Njenge [20 kunye ne-Q [20] ngokulandelanayo, egameni lecandelo lokuphakama kwe-200mm yentsimbi eqhelekileyo yentsimbi kunye nentsimbi yentsimbi. I-beam.

 

4. intsimbi engile
Intsimbi yeAngle yahlulwe yaba ziindidi ezimbini zentsimbi elinganayo nentsimbi engalinganiyo.
I-engeli elinganayo: i-equilateral angle yayo i-perpendicular emacala amabini anobude obulinganayo, imodeli yayo enophawu "L" kunye nobubanzi belungu x ubukhulu be-millimeters, njenge-L100x10 kububanzi belungu be-100mm, ubukhulu bemilenze buyi-10mm elinganayo elinganayo.
Ii-angles ezingalinganiyo: i-perpendicular perpendicular yayo i-perpendicular ezimbini azilingani, imodeli enesimboli "" kunye nobubanzi bemilenze emide x ububanzi obufutshane bemilenze x ububanzi bemilenze kwiimilimitha, njenge-L100x80x8 kububanzi obuyi-100mm ubude, ububanzi obufutshane be-80mm, ubukhulu bemilenze ye-8mm engalinganiyo.

 
5. H-umqadi(iqengqelekisiwe yadityaniswa)
I-H-beam yahlukile kwi-I-beam.
(1) i-flange ebanzi, ngoko kuye kwakho i-flange ebanzi ebizwa ngokuba yi-I-beam.
(2) Umgangatho wangaphakathi we-flange awudingi ukuba ne-slope, iindawo eziphezulu kunye nezantsi zihambelana.
(3) ukusuka kwifom yokusasazwa kwezinto eziphathekayo, i-I-beam cross-section yezinto eziphathekayo igxininiswe kakhulu kwiwebhu ejikelezayo, ngakumbi ukuya emacaleni okwandisa, intsimbi encinci, kunye ne-H-beam eqengqelekayo, ukuhanjiswa kwezinto kugxininise emphethweni wenxalenye.
Ngenxa yoko, iimpawu ze-H-beam cross-section ngokucacileyo ziphezulu kumsebenzi wendabuko, ishaneli, i-angle kunye nokudibanisa kwabo kwecandelo, ukusetyenziswa kweziphumo zoqoqosho ezingcono.
Ngokomgangatho wangoku wesizwe "hot rolled H-beam kunye necandelo T-beam" (GB/T11263-2005), i-H-beam yahlulahlulwe yangamacandelo amane, atyunjwe ngolu hlobo lulandelayo: i-flange ebanzi H-beam - HW (W for Wide English prefix), iinkcukacha ezivela kwi-100mmx100mm ~ 400mmx40; iflange ephakathi H-beam - HM (M for Middle IsiNgesi isimaphambili), iinkcukacha ukusuka Specification ukusuka 150mmX100mm ~ 600mmX300mm: Imxinwa Cui-edge H-beam - HN (N for Narrow IsiNgesi isimaphambili); I-H-beam enodonga olucekeceke - HT (T ye-Thin English prefix). Ukumakishwa kwenkcazo ye-H-beam kuyasetyenziswa: H kunye nexabiso lobude bexabiso le-h x ububanzi bexabiso le-b x ixabiso lobukhulu bexabiso lewebhu t ixabiso x ixabiso lobukhulu bexabiso le-flange t2 lithe. Okufana ne-H800x300x14x26, oko kukuthi, ubude becandelo le-800mm, ububanzi be-flange yi-300mm, ubukhulu bewebhu bu-14mm, ubukhulu be-flange be-26mm H-beam. Okanye ivakaliswe kuqala ngeesimboli HWHM kunye HN wathi udidi H-beam, ilandelwa "ubude (mm) x ububanzi (mm)", ezifana HW300x300, oko kukuthi, ubude icandelo 300mm, flange ububanzi 300mm ububanzi flange H-beam.
6. T-umqadi
I-Sectional T-beam (Figure) ihlukaniswe ngamacandelo amathathu, ikhowudi ilandelayo: inxalenye ebanzi ye-flange ye-T-beam - TW (W kwi-Wide IsiNgesi intloko); kwi-flange inxalenye ye-T-beam - TM (M yentloko yesiNgesi esiphakathi); iflange emxinwa inxalenye ye-T-beam - TN (N yentloko yesiNgesi emxinwa). I-T-beam yeCandelo yi-H-beam ehambelanayo phakathi kwewebhu elinganayo yahlulwe ibe. Iinkcukacha zeCandelo T-umqadi ophawulwe nge: T kunye nobude h ixabiso x ububanzi b ixabiso x web ubukhulu t ixabiso x flange ubukhulu t ixabiso. Okufana ne-T248x199x9x14, oko kukuthi, ubude becandelo le-248mm, ububanzi bephiko yi-199mm, ubukhulu bewebhu bu-9mm, ubukhulu be-flange be-14mm T-beam. Inokusetyenziswa kwakhona kunye H-beam ukumelwa efanayo, ezifana TN225x200 oko kukuthi, ubude icandelo 225mm, flange ububanzi 200mm emxinwa icandelo flange T-beam.

7.umbhobho wentsimbi yesakhiwo
Umbhobho wensimbi njengenxalenye ebalulekileyo yeemveliso zentsimbi kunye nentsimbi, ngenxa yenkqubo yokuvelisa kunye nokumila kombhobho osetyenziswa kwizinto ezimbi kwaye yahlulweumbhobho wentsimbi ongenamthungo(ujikeleze kakubi) kunyeumbhobho wentsimbi odityanisiweyo(ipleyiti, nembi) iindidi ezimbini, bona Umfanekiso.
Ulwakhiwo lwentsimbi edla ngokusetyenziswa kumbhobho wentsimbi engenamthungo eshushu kunye nombhobho wentsimbi odityanisiweyo, umbhobho wentsimbi odityanisiweyo waqengqeleka wadityaniswa ukusuka kumcu wentsimbi, ngokobungakanani bobubanzi bombhobho, kwaye yahlulwe yaba ziindidi ezimbini zokuwelda okuthe tye kunye nokuwelda okujikelezayo.Umbhobho wentsimbi we-LSAWiinkcukacha ze-diameter yangaphandle ye-32 ~ 152mm, ubukhulu bodonga lwe-20 ~ 5.5mm. imigangatho kazwelonke ye "LSAW ipayipi yensimbi" (GB/T13793-2008). Umbhobho wentsimbi yolwakhiwo olungenamthungo ngokomgangatho wesizwe "umbhobho wentsimbi engenamthungo" (GB/T8162-2008), kukho iindidi ezimbini zombhobho oshushu oqengqelekayo kwaye otsalwa ngokubanda, otsalwa ngokubanda ukhawulelwe kububanzi bombhobho omncinci, umbhobho wentsimbi eshushu-isolwe ingenamthungo ububanzi obungaphandle be-32 ~ 630mm, ubukhulu bodonga lwe-25mm ~ 75mm.
Iinkcukacha ngaphandle kwedayamitha x ubukhulu bodonga (mm), njenge φ102x5. Umbhobho wensimbi odibeneyo ugobile kwaye udityaniswe ngumgca wensimbi, ixabiso liphantsi. Steel umbhobho cross-icandelo symmetry unikezelo ummandla iliso kusengqiqweni, umzuzu inertia kuzo zonke iinkalo kunye radius of gyration iyafana kwaye inkulu, ngoko ukusebenza amandla, ingakumbi xa uxinzelelo axial ngcono, kwaye imilo igophe layo kwenza kube ukuxhathisa ngaphantsi umoya, amaza, umkhenkce, kodwa ixabiso libiza kakhulu kwaye ulwakhiwo loqhagamshelo luhlala lunzima ngakumbi.
