Ungayikhetha njani i-H Beam efanelekileyo kwiShishini loLwakhiwo?

Kwishishini lokwakha,Imiqadi ye-Hzaziwa ngokuba "ziisiseko sezakhiwo ezithwala imithwalo"—ukukhetha kwazo okunengqiqo kumisela ngokuthe ngqo ukhuseleko, ukuqina, kunye nokusebenza kakuhle kweendleko zeeprojekthi. Ngokwandiswa okuqhubekayo kokwakhiwa kweziseko zophuhliso kunye neemarike zezakhiwo eziphakamileyo, indlela yokukhetha imiqadi ye-H ehambelana neemfuno zeprojekthi kwiimveliso ezahlukeneyo iye yaba yingxaki ephambili kwiinjineli kunye namaqela okuthenga. Apha ngezantsi kukho isikhokelo esineenkcukacha esigxile kwiimpawu eziphambili, iimpawu ezizodwa, kunye neemeko zokusetyenziswa kwemiqadi ye-H ukunceda abadlali beli shishini benze izigqibo zesayensi.

Qala ngeempawu eziphambili: Qonda "iMigangatho eSisiseko" ye-H Beams

Ukukhethwa kweemitha ze-H kufuneka kuqala kusekelwe kwiimpawu ezintathu eziphambili ezingaxoxiswaniyo, njengoko ezi zinxulumene ngokuthe ngqo nokuba imveliso ingahlangabezana neemfuno zoyilo lwesakhiwo.

Ibanga lezinto：Ezona zinto zixhaphakileyo kwi-H beams yi-carbon structural steel (ezifanaI-Q235B, i-Q355B H Beamkwimigangatho yaseTshayina, okanyeUmqadi we-A36, A572 Hngokwemigangatho yaseMelika) kunye nentsimbi enamandla aphantsi. I-Q235B/A36 H Beam ifanelekile kulwakhiwo lwezakhiwo ngokubanzi (umz., izakhiwo zokuhlala, iifektri ezincinci) ngenxa yokudityaniswa kwayo kakuhle kunye neendleko eziphantsi; I-Q355B/A572, enamandla aphezulu okuvelisa (≥355MPa) kunye namandla okutsalwa, ikhethwa kakhulu kwiiprojekthi ezinzima ezifana neebhulorho, iiworkshop ezinkulu, kunye neentloko zezakhiwo eziphakamileyo, njengoko inokunciphisa ubungakanani be-cross-sectional beam kwaye yonge indawo.

Iinkcukacha zoBume: Imiqadi ye-H ichazwa ngemilinganiselo emithathu ephambili: ukuphakama (H), ububanzi (B), kunye nobukhulu bewebhu (d). Umzekelo, umqadi we-H obhalwe "H300×150×6×8"ithetha ukuba inobude obuyi-300mm, ububanzi obuyi-150mm, ubukhulu bewebhu obuyi-6mm, kunye nobukhulu beflange obuyi-8mm. Iibhama ze-H ezincinci (H≤200mm) zihlala zisetyenziselwa izakhiwo zesibini ezifana neejoyinti zomgangatho kunye neenkxaso zokwahlulahlula; ezo ziphakathi (200mm＜H＜400mm) zisetyenziswa kwiibhama eziphambili zezakhiwo ezinemigangatho emininzi kunye nophahla lwefektri; iibhama ze-H ezinkulu (H≥400mm) azinamsebenzi kwiibhama eziphakamileyo kakhulu, iibhulorho ezinde, kunye namaqonga ezixhobo zoshishino.

Ukusebenza koomatshini: Gxila kwizalathisi ezinje ngamandla okuvelisa, amandla okutsalwa, kunye nokuqina kwempembelelo. Kwiiprojekthi ezikwimimandla ebandayo (umz., emantla eTshayina, eKhanada), imisebe ye-H kufuneka iphumelele uvavanyo lwempembelelo oluphantsi (njengokuqina kwempembelelo -40℃ ≥34J) ukuze kuthintelwe ukwaphuka okubuthathaka kwiimeko zokuqandisa; kwiindawo ezinenyikima, iimveliso ezine-ductility elungileyo (ukude ≥20%) kufuneka zikhethwe ukuphucula ukumelana nenyikima kwesakhiwo.

Sebenzisa iimpawu ezizodwa: Thelekisa "iingenelo zeMveliso" neemfuno zeProjekthi

Xa kuthelekiswa namacandelo entsimbi yendabuko afanaImisebe ye-Ikunye neentsimbi zetshaneli, imiqadi ye-H ineempawu ezahlukeneyo zokwakha ezenza zifaneleke kwiimeko ezithile zokwakha—ukuqonda ezi nzuzo kubalulekile ekukhetheni okujoliswe kuko.

Ukusebenza kakuhle kokuthwala umthwalo: I-cross-section ye-H beams ye-H isasaza izinto ngendlela eqiqileyo ngakumbi: ii-flanges ezijiyileyo (iindawo eziphezulu nezisezantsi ezithe tye) zithwala uninzi lomzuzu wokugoba, ngelixa i-web encinci (inxalenye ephakathi ethe nkqo) imelana namandla okucheba. Olu yilo luvumela ii-H beams ukuba zifikelele kumthamo ophezulu wokuthwala umthwalo ngokusetyenziswa okuncinci kwentsimbi—xa kuthelekiswa nee-I-beams ezinobunzima obufanayo, ii-H beams zinamandla okugoba aphezulu nge-15%-20%. Olu phawu luzenza zilungele iiprojekthi ezilandela ukonga iindleko kunye nezakhiwo ezikhaphukhaphu, ezifana nezakhiwo ezenziwe kwangaphambili kunye nokwakhiwa kwemodyuli.

Uzinzo Oluqinileyo kunye Nokufakwa Okulula: I-symmetric H cross-section inciphisa ukuguquguquka kwe-torsional ngexesha lokwakha, okwenza imiqadi ye-H izinze ngakumbi xa isetyenziswa njengemiqadi ephambili ethwala umthwalo. Ukongeza, iiflange zazo ezithe tyaba kulula ukuzidibanisa nezinye izinto (umz., iibholiti, ii-welds) ngaphandle kokucubungula okuntsonkothileyo—oku kunciphisa ixesha lokwakha kwindawo nge-30% xa kuthelekiswa namacandelo entsimbi angacwangciswanga, nto leyo ibalulekileyo kwiiprojekthi ezikhawulezayo ezifana nee-complexes zorhwebo kunye neziseko zophuhliso ezingxamisekileyo.

Ukugqwala Okulungileyo kunye nokuxhathisa umlilo (ngonyango): Imisebe ye-H engacutshungulwanga idla ngokuba nomhlwa, kodwa emva konyango oluphezulu olufana ne-hot-dip galvanizing okanye i-epoxy coating, inokumelana nomhlwa kwiindawo ezifumileyo okanye ezinxwemeni (umz., amaqonga aselunxwemeni, iindlela zaselunxwemeni). Kwiimeko zobushushu obuphezulu ezifana neeworkshops zoshishino ezinezitofu, imisebe ye-H engatshiyo (egqunywe ngepeyinti ethintela umlilo) inokugcina amandla okuthwala umthwalo ngaphezulu kwemizuzu eli-120 xa kutsha, ihlangabezana nemigangatho yokhuseleko lomlilo oluqinileyo.

Imeko zesicelo esijolise kuso: Ukhetho oluLungileyo

Iiprojekthi zokwakha ezahlukeneyo zineemfuno ezahlukeneyo ze-H-beams. Kuphela ngokulungelelanisa iipropati zemveliso neemfuno zesiza apho ixabiso lazo linokunyuswa khona. Ezi zilandelayo ziimeko ezintathu eziqhelekileyo zokusetyenziswa kunye nemixube ecetyiswayo.

Izakhiwo Eziphakamileyo Zokuhlala Nezorhwebo: Kwizakhiwo ezinemigangatho eli-10-30, kucetyiswa ii-H-beams eziphakathi ezenziwe ngentsimbi ye-Q355B (H250×125×6×9 ukuya kwi-H350×175×7×11). Amandla azo aphezulu axhasa ubunzima beemigangatho emininzi, ngelixa ubukhulu bazo obuncinci bugcina indawo yoyilo lwangaphakathi.

Iibhulorho kunye neZakhiwo ezinde: Iibhulorho ezinde (ezinobubanzi obuyi-≥50 yeemitha) okanye uphahla lwenkundla lufuna ii-H-beams ezinkulu neziqinileyo (H400×200×8×13 nangaphezulu).

Izityalo zeMizi-mveliso kunye neeNdawo zokugcina impahla: Izityalo ezithwala umthwalo onzima (ezifana nezityalo zokwenza iimoto) kunye neendawo zokugcina impahla ezinkulu zifuna ii-H-beams ezikwaziyo ukuxhasa ubunzima bezixhobo okanye ukuqokelela imithwalo.
