Iindidi kunye neenkcukacha zentsimbi

I. Ipleyiti yentsimbi kunye ne-Strip
Ipleyiti yentsimbiYahlulwe yaba yipleyiti yentsimbi etyebileyo, ipleyiti yentsimbi ebhityileyo kunye nentsimbi ethe tyaba, iinkcukacha zayo zinophawu "a" kunye nobubanzi x ubukhulu x ubude ngeemilimitha. Ezifana: ipleyiti yentsimbi eyi-300x10x3000 enobubanzi obuyi-300mm, ubukhulu obuyi-10mm, ubude bepleyiti yentsimbi eyi-3000mm.

Ipleyiti yentsimbi etyebileyo: ubukhulu bayo bungaphezulu kwe-4mm, ububanzi buyi-600~3000mm, ubude buyi-4~12m.
Ipleyiti yentsimbi ebhityileyo: ubukhulu bungaphantsi kwe-4mm, ububanzi buyi-500~1500mm, ubude buyi-0.5~4m.
Intsimbi ethe tyaba:ubukhulu 4~60mm, ububanzi 12~200mm, ubude 3~9m.
Iipleyiti zentsimbi kunye nemicu zihlulwe ngokwendlela yokuqengqeleka:iipleyiti ezisongiweyo ezibandayokwayeiipleyiti ezisongiweyo ezishushu; ngokobukhulu: iipleyiti zentsimbi ezibhityileyo (ngaphantsi kwe-4mm), iipleyiti zentsimbi ezityebileyo (4-60mm), iipleyiti ezityebileyo kakhulu (ngaphezu kwe-60mm)

2. intsimbi eqengqelekayo eshushu
2.1Umqadi we-I
Intsimbi ye-I-beam njengoko igama layo lisitsho, yiprofayili ye-cross-section emile okwe-I, iiflanges eziphezulu nezisezantsi zithambile.
Intsimbi ye-I-beam yahlulwe yaba bububanzi obuqhelekileyo, obukhanyayo nobuphiko beentlobo ezintathu, kunye nophawu "lomsebenzi" kunye nenani le-said. Yeyiphi inombolo emele ukuphakama kwecandelo lenani leesentimitha. 20 kunye ne-32 ngaphezulu kwe-I-beam eqhelekileyo, inani elifanayo kwaye lahlulwe laba yi-a, b kunye ne-a, b, c uhlobo, ubukhulu bayo bewebhu kunye nobubanzi beflange ngokulandelelanayo yi-2mm. ezifana ne-T36a ukuba ukuphakama kwecandelo elinqamlezileyo le-360 mm, ubukhulu bewebhu bodidi lwe-I-beam eqhelekileyo. I-beams kufuneka zizame ukusebenzisa ubukhulu bewebhu obuncinci bohlobo lwe-a, obubangelwa bubunzima bayo obulula, ngelixa umzuzu wecandelo elinqamlezileyo we-inertia mkhulu kakhulu.
Ixesha lokungakhathali kunye nobubanzi be-I-beams kwicala lobubanzi zincinci kakhulu kunezo zikwicala lokuphakama. Ke ngoko, kukho imida ethile ekusetyenzisweni kwayo, efanelekile ngokubanzi kumalungu agoba ngendlela enye.
3.intsimbi yetshaneli
Intsimbi yetshaneli yahlulwe yaba ziintlobo ezimbini zentsimbi yetshaneli eqhelekileyo kunye nentsimbi yetshaneli ekhaphukhaphu. Uhlobo lwentsimbi yetshaneli enophawu “[””] kunye nenani le-“said”. Ngokufanayo ne-I-beam, inani leesentimitha likwamele ukuphakama kwecandelo elinqamlezileyo. Ezifana no-[20 kunye no-Q [20 ngokulandelanayo, egameni lokuphakama kwecandelo le-200mm yentsimbi yetshaneli eqhelekileyo kunye nentsimbi yetshaneli ekhaphukhaphu. 14 kunye nentsimbi yetshaneli eqhelekileyo engaphezulu kwama-24, inani elifanayo le-sub-a, b kunye no-a, b, c, intsingiselo efanayo ne-I-beam.

 

4. intsimbi ye-engile
Intsimbi ye-Angle yahlulwe yaba ziintlobo ezimbini zentsimbi ye-equilateral angle kunye nentsimbi ye-equal angle.
I-engile elinganayo: imilenze yayo emibini ethe nkqo ngokulinganayo, imodeli yayo enophawu "L" kunye nobubanzi bemilenze x ubukhulu bemilenze kwiimilimitha, njenge-L100x10 yobubanzi bemilenze ye-100mm, ubukhulu bemilenze ye-engile elinganayo ye-10mm.
Ii-engile ezingalinganiyo: amalungu ayo amabini ami nkqo alinganayo, imodeli enophawu "" kunye nobubanzi bamalungu amade x ububanzi bamalungu amafutshane x ubukhulu bamalungu ngamamilimitha, njenge-L100x80x8 yobubanzi bamalungu amade obuyi-100mm, ububanzi bamalungu amafutshane obuyi-80mm, ubukhulu bamalungu obuyi-8mm engile engalinganiyo.

 
5. Umqadi we-H(igoqwe kwaye idityanisiwe)
Umqadi we-H wahlukile kumqadi we-I.
(1) iflange ebanzi, ngoko ke kubekho iflange ebanzi ye-I-beam.
(2) Umphezulu ongaphakathi weflange akufuneki ube nomthambeka, umphezulu ophezulu nowasezantsi uhambelana.
(3) ukusuka kwimo yokusasazwa kwezinto, icandelo elinqamlezileyo le-I-beam lezinto ligxile kakhulu kwiwebhu ejikeleze, okukhona kuphezulu emacaleni olwandiso, intsimbi encinci, kunye ne-H-beam eqengqelekayo, ugxininiso lokusasazwa kwezinto lukwicala lenxalenye.
Ngenxa yesi sizathu, iimpawu ze-H-beam cross-section ngokucacileyo zingcono kunendlela eqhelekileyo yokusebenza, itshaneli, i-angle kunye nokudibanisa kwazo i-cross-section, ukusetyenziswa kweziphumo ezingcono zoqoqosho.
Ngokwemigangatho yesizwe yangoku "i-hot rolled H-beam kunye ne-section T-beam" (GB/T11263-2005), i-H-beam yahlulwe yangamacandelo amane, achazwe ngolu hlobo lulandelayo: i-wide flange H-beam - HW (W yesiqalo sesiNgesi esibanzi), iinkcukacha ukusuka kwi-100mmx100mm ~ 400mmx400mm; i-middle flange H-beam - HM (M yesiqalo sesiNgesi esiphakathi), iinkcukacha ezivela kwiNkcazelo ukusuka kwi-150mmX100mm ~ 600mmX300mm: i-Narrow Cui-edge H-beam - HN (N yesiqalo sesiNgesi esincinci); i-thin-walled H-beam - HT (T yesiqalo sesiNgesi esincinci). Kusetyenziswa uphawu lwenkcazo ye-H-beam: H kunye nexabiso lokuphakama kwexabiso le-h x ububanzi bexabiso le-b x ixabiso lobukhulu bexabiso lewebhu le-t x ixabiso lobukhulu bexabiso le-t2 le-flange elichaziweyo. Ezifana ne-H800x300x14x26, oko kukuthi, ubude becandelo le-800mm, ububanzi be-flange buyi-300mm, ubukhulu bewebhu buyi-14mm, ubukhulu be-flange buyi-26mm H-beam. Okanye zichazwe kuqala ngeempawu ze-HWHM kunye ne-HN ezithi udidi lwe-H-beam, zilandelwa "bubude (mm) x ububanzi (mm)", ezifana ne-HW300x300, oko kukuthi, ubude becandelo le-300mm, ububanzi be-flange buyi-300mm ububanzi be-flange H-beam.
6. Umqadi we-T
I-T-beam yeCandelo (Umfanekiso) yahlulwe yangamacandelo amathathu, ikhowudi yile ilandelayo: inxalenye yeflange ebanzi ye-T-beam - TW (W yentloko yesiNgesi ebanzi); kwinxalenye yeflange ye-T-beam - TM (M yentloko yesiNgesi esiPhakathi); inxalenye yeflange emxinwa ye-T-beam - TN (N yentloko yesiNgesi esiNcinci). I-T-beam yeCandelo yi-H-beam ehambelanayo embindini wewebhu ilingana yahlulwe ibe. Iinkcukacha ze-T-beam yeCandelo ziphawulwe ngolu hlobo: T kunye nokuphakama ixabiso le-h x ububanzi ixabiso le-b x ubukhulu bewebhu ixabiso le-t x ubukhulu beflange ixabiso le-t. Ezifana ne-T248x199x9x14, oko kukuthi, kubude becandelo le-248mm, ububanzi bephiko le-199mm, ubukhulu bewebhu be-9mm, ubukhulu beflange be-14mm T-beam. Ingasetyenziswa kwakhona nge-H-beam efana nayo, efana ne-TN225x200, oko kukuthi, ubude becandelo le-225mm, ububanzi beflange ye-200mm emxinwa ye-flange section T-beam.

7. umbhobho wentsimbi yesakhiwo
Umbhobho wentsimbi njengenxalenye ebalulekileyo yeemveliso zentsimbi kunye nentsimbi, ngenxa yenkqubo yawo yokuvelisa kunye nemilo yombhobho osetyenziswa kwiintlobo ezahlukeneyo zenkunkuma kwaye wahlulwe wabaumbhobho wentsimbi ongenamthungo(ijikelezwe imbi) kwayeumbhobho wentsimbi odibeneyo(ipleyiti, ene-bad) iindidi ezimbini, jonga uMfanekiso.
Isakhiwo sentsimbi sisetyenziswa kakhulu kumbhobho wentsimbi ongenamthungo ojijekileyo oshushu kunye nombhobho wentsimbi ojijekileyo, umbhobho wentsimbi ojijekileyo ojijekileyo ojijekileyo osuka kumcu wentsimbi, ngokobukhulu bombhobho, kwaye wahlulwe waba ziintlobo ezimbini zokujijela umthungo othe tye kunye nokujijela okujikelezayo.Umbhobho wentsimbi we-LSAWiinkcukacha zobubanzi bangaphandle obuyi-32 ~ 152mm, ubukhulu bodonga obuyi-20 ~ 5.5mm. imigangatho yesizwe ye-"LSAW steel pipe" (GB/T13793-2008). Umbhobho wentsimbi engenamthungo ngokwemigangatho yesizwe "umbhobho wentsimbi engenamthungo" (GB/T8162-2008), kukho iintlobo ezimbini zombhobho oqengqelekayo oshushu notsalwa ngokubanda, umbhobho otsalwa ngokubanda unqunyelwe kububanzi bombhobho omncinci, umbhobho wentsimbi engenamthungo oshushu obuyi-32 ~ 630mm, ubukhulu bodonga obuyi-25 ~ 75mm.
Iinkcukacha ezicacileyo ububanzi obungaphandle x ubukhulu bodonga (mm), ezifana ne-φ102x5. Umbhobho wentsimbi odibeneyo ugobile kwaye udityaniswe ngumcu wentsimbi, ixabiso liphantsi kakhulu. Ukusasazwa kwendawo yeliso yepayipi yentsimbi kuyaqondakala, ixesha lokungakhathali kuzo zonke iindlela kunye nobubanzi be-gyration liyafana kwaye likhulu, ngoko ke ukusebenza kwamandla, ingakumbi xa uxinzelelo lwe-axial lungcono, kunye nesimo salo sejika kwenza ukuba ingaxhathisi kakhulu emoyeni, kumaza, kumkhenkce, kodwa ixabiso libiza kakhulu kwaye isakhiwo soqhagamshelo sidla ngokuba nzima ngakumbi.
