Intshayelelo eyiSiseko ye-H-Beam
1. Inkcazo kunye noLwakhiwo oluSisiseko
Iiflange: Iipleyiti ezimbini ezihambelanayo, ezithe tye zobubanzi obufanayo, zithwele umthwalo ophambili wokugoba.
Web: Icandelo eliphakathi elithe nkqo elidibanisa iiflange, ukuxhathisa imikhosi yokucheba.
IH-umqadiIgama livela ku "H"-njengemilo enqamlezileyo yecandelo. Ngokungafaniyo neI-beam(I-beam), iiflange zayo zibanzi kwaye zithe tyaba, zibonelela ngokuxhathisa okukhulu ukugoba kunye nemikhosi yokugoba.
2. Iimpawu zobuGcisa kunye neNkcazo
Izixhobo kunye neMigangatho: Izinto zentsimbi ezisetyenziswa ngokuqhelekileyo ziquka i-Q235B, i-A36, i-SS400 (i-carbon steel), okanye i-Q345 (insimbi ephantsi kwe-alloy), ehambelana nemigangatho yamazwe ngamazwe njenge-ASTM kunye ne-JIS.
Uluhlu lobungakanani (iinkcukacha eziqhelekileyo):
| Inxalenye | Uluhlu lweParameter |
| Ubude bewebhu | 100-900 mm |
| Web ubukhulu | 4.5-16 mm |
| Ububanzi beflange | 100-400 mm |
| Ubukhulu becala | 6–28 mm |
| Ubude | Umgangatho we-12m (unokwenziwa ngokwezifiso) |
Inzuzo yamandla: Uyilo olubanzi lwe-flange lulungiselela ukuhanjiswa komthwalo, kwaye ukuxhathisa ukugoba kungaphezulu kwe-30% ephezulu kune-I-beam, okwenza ukuba ilungele iimeko zomthwalo onzima.
3. Izicelo eziphambili
Ulwakhiwo lweZakhiwo: Iikholomu kwizakhiwo eziphakamileyo kunye neetrasi zephahla kwiifektri ezinkulu ze-span zibonelela ngenkxaso engundoqo yokuthwala umthwalo.
Iibhulorho kunye noomatshini abanzima: Iigidi zeCrane kunye neebhulorho kufuneka zimelane nemithwalo eguquguqukayo kunye noxinzelelo lokukhathala.
Umzi-mveliso noThutho: Iidekhi zeenqanawa, i-chassis kaloliwe, kunye neziseko zezixhobo zixhomekeke kumandla azo aphezulu kunye neempawu ezikhaphukhaphu.
Izicelo eziKhethekileyo: Iintonga zokudibanisa ze-H kwiinjini zemoto (ezifana ne-injini ye-Audi 5-cylinder) zenziwe ngentsimbi ye-4340 chromium-molybdenum ukumelana namandla aphezulu kunye nesantya.
4. Izinto eziluncedo kunye neMiba engundoqo
Ezoqoqosho: Umlinganiselo ophezulu wamandla-to-weight unciphisa ukusetyenziswa kwezinto kunye neendleko zizonke.
Uzinzo: Iipropati ezigqwesileyo ezidityanisiweyo eziguquguqukayo kunye ne-torsional ziyenza ifaneleke ngokukodwa kwizakhiwo ezikwiindawo ezithandwa ziinyikima okanye ezo ziphantsi kwemithwalo ephezulu yomoya.
Ulwakhiwo olulula: Ujongano olusemgangathweni lwenza lula ukudibanisa kwezinye izakhiwo (ezifana ne-welding kunye ne-bolting), ukunciphisa ixesha lokwakha.
Ukuqina: I-Hot-rolling iphakamisa ukuxhathisa ukukhathala, okukhokelela kubomi benkonzo obungaphezu kweminyaka engama-50.
5. Iintlobo eziKhethekileyo kunye neeNguqulelo
Wide Flange Beam (Viga H Alas Anchas): Ifaka iiflange ezibanzi, ezisetyenziselwa iziseko zoomatshini abanzima.
HEB Beam: Iiflange ezihambelanayo eziphezulu, ezilungiselelwe iziseko ezinkulu (ezifana neebhulorho zesitimela ezihamba ngesantya esiphezulu).
Umtha oLaminated (Viga H Laminada): I-Hot-rolled ye-weldability ephuculweyo, ifanelekile kwiifreyimu zesakhiwo sentsimbi enzima.
Ukusetyenziswa kwe-H-Beam
1. Ulwakhiwo lweZakhiwo:
Ulwakhiwo loLuntu: Isetyenziswe kwizakhiwo zokuhlala kunye nezorhwebo, ukubonelela ngenkxaso yesakhiwo.
Izityalo zoShishino: H-imiqadizithandwa kakhulu kwizityalo ezibanzi kunye nezakhiwo eziphakamileyo ngenxa yomthamo wazo obalaseleyo wokuthwala kunye nokuzinza.
Izakhiwo eziphakamileyo: Amandla aphezulu kunye nokuzinza kwe-H-beams kwenza kube yinto efanelekileyo yokukhetha iindawo ezixhatshazwa yinyikima kunye neendawo eziphakamileyo zokushisa.
2. Ubunjineli beebhulorho:
Iibhulorho ezinkulu: I-H-beams isetyenziswe kwi-beam kunye nezakhiwo zekholomu zeebhuloho, ukuhlangabezana neemfuno ze-spans ezinkulu kunye nomthamo ophezulu wokuthwala.
3. Amanye amashishini:
Izixhobo ezinzima: Imiqadi ye-H isetyenziselwa ukuxhasa oomatshini abanzima kunye nezixhobo.
Oohola bendlela: Isetyenziswa kwiibhulorho kunye nezakhiwo zendlela.
Iifreyimu zeenqanawa: Amandla kunye nokumelana nokubola kwe-H-beams kubenza bafaneleke ukwakhiwa kweenqanawa.
Inkxaso yam:Isetyenziswa kwiziseko zenkxaso kwimigodi engaphantsi komhlaba.
Ukuphuculwa koMhlaba kunye nobuNjineli beDama: Imiqadi ye-H ingasetyenziselwa ukuqinisa iziseko kunye namadama.
Amacandelo oomatshini: Iindidi ezahlukeneyo zobukhulu kunye neenkcukacha ze-H-beams nazo zenza ukuba zibe yinto eqhelekileyo kwimveliso yomatshini.
