Ungawukhetha njani umtha oLungileyo we-H kuShishino loKwakha?

Kushishino lokwakha,H imiqadizaziwa ngokuba "ngumqolo wezakhiwo ezithwele umthwalo" -ukhetho lwabo olunengqiqo lumisela ngokuthe ngqo ukhuseleko, ukuqina, kunye nokuphumelela kweendleko zeeprojekthi. Ngokwandiswa okuqhubekayo kolwakhiwo lweziseko ezingundoqo kunye neemarike zokwakha eziphakamileyo, indlela yokukhetha imiqadi ye-H ehambelana neemfuno zeprojekthi ukusuka kuluhlu olubanzi lweemveliso ibe ngumba ophambili kwiinjineli kunye namaqela okuthenga. Apha ngezantsi kukho isikhokelo esineenkcukacha esijolise kwiimpawu eziphambili, iimpawu ezizodwa, kunye neemeko zesicelo semiqadi ye-H ukunceda abadlali beshishini benze izigqibo zenzululwazi.

Qala ngeeMpawu eziPhambili: Bamba "iMigangatho eSisiseko" yeeBeams

Ukukhethwa kweentsimbi ze-H kufuneka kuqala kusekelwe kwiimpawu ezingundoqo ezintathu ezingenakuxoxisana, njengoko ezi zihambelana ngokuthe ngqo nokuba imveliso ingahlangabezana neemfuno zoyilo lwesakhiwo.

IBanga leMathiriyeli: Ezona zixhobo zixhaphakileyo kwimiqadi ye-H yintsimbi yolwakhiwo lwekhabhoni (enjeQ235B, Q355B H Umqadikwimigangatho yaseTshayina, okanyeA36, A572 H Beamkwimigangatho yaseMelika) kunye nentsimbi ephantsi yealloyi ephezulu. I-Q235B/A36 H Beam ilungele ulwakhiwo jikelele (umzekelo, izakhiwo zokuhlala, iifektri ezincinci) ngenxa yokuqina kwayo kakuhle kunye neendleko eziphantsi; I-Q355B / A572, enegunya eliphezulu lokuvunwa (≥355MPa) kunye namandla okuqina, ikhethwa kwiiprojekthi ezinobunzima obufana neebhulorho, ii-workshops ezinkulu, kunye nezixhobo zokwakha eziphakamileyo, njengoko kunokunciphisa ubukhulu be-cross-section of the beam kunye nokugcina indawo.

Imiba yoMda: Imiqadi ye-H ichazwa ngemilinganiselo emithathu ebalulekileyo: ukuphakama (H), ububanzi (B), kunye nobukhulu bewebhu (d). Umzekelo, umqa we-H obhalwe "H300×150×6×8"ithetha ukuba inobude obuyi-300mm, ububanzi obuyi-150mm, ubukhulu bewebhu buyi-6mm, kunye nobukhulu beflange obuyi-8mm. Imiqadi ye-H ebukhulu obuncinci (H≤200mm) isoloko isetyenziselwa izakhiwo zesibini ezifana nezihlanganisi zomgangatho kunye nezixhaso zokwahlulahlula; ezinobukhulu obuphakathi (200mm＜H＜H＜400mm) izakhiwo zophahla lwezakhiwo ezinkulu zefektri zifakwa kwizakhiwo ezinkulu zophahla lwendlu yolwakhiwo; Imiqadi ye-H (H≥400mm) iyimfuneko ekunyukeni okuphezulu okuphezulu, iibhulorho ezinde, kunye namaqonga ezixhobo zoshishino.

Ukusebenza koomatshini: Gxininisa kwizikhombisi ezifana namandla esivuno, amandla okuqina, kunye nokuqina kwempembelelo. Kwiiprojekthi kwimimandla ebandayo (umzekelo, emantla eTshayina, eKhanada), imiqadi ye-H kufuneka iphumelele iimvavanyo zempembelelo zobushushu obuphantsi (ezifana ne -40℃ ukuqina kwempembelelo ≥34J) ukunqanda ukuphuka kwe-brittle kwiimeko zeqhwa; kwimimandla yenyikima, iimveliso ezine-ductility elungileyo (i-elongation ≥20%) kufuneka zikhethwe ukwandisa ukuxhathisa kwesakhiwo.

Ukwandisa iimpawu eziZodwa: Tshatisa "IiNgcebiso zeMveliso" kwiiMfuno zeProjekthi

Xa kuthelekiswa namacandelo zentsimbi zemveli ezifanaI-imiqadikunye neentsimbi ze-channel, izibonda ze-H zineempawu ezicacileyo zesakhiwo ezenza ukuba zilungele iimeko ezithile zokwakha-ukuqonda ezi nzuzo zingundoqo ekukhethweni okujoliswe kuyo.

UkuFaniswa koMthwalo ophezulu ngokuSebenzayo: I-cross-shaped cross-section ye-H ye-beams isasaza izinto ngokufanelekileyo: iiflange ezixubileyo (iindawo eziphezulu kunye nezisezantsi ezinqamlekileyo) zithwala ixesha elininzi lokugoba, ngelixa i-web encinci (inxalenye ephakathi ethe nkqo) ixhathisa amandla okucheba. Olu luyilo luvumela ii-H ukuba zifezekise umthamo ophezulu wokuthwala imithwalo kunye nokusetyenziswa kwentsimbi encinci-ngokuthelekiswa ne-I-beams yobunzima obufanayo, i-H imiqadi ine-15% -20% ephezulu yokugoba amandla. Olu phawu lubenza balungele iiprojekthi ezilandela ukonga iindleko kunye nezakhiwo ezikhaphukhaphu, ezifana nezakhiwo ezenziwe ngaphambili kunye nokwakhiwa kweemodyuli.

Uzinzo olomeleleyo kunye noFakelo oluLula: I-symmetric H cross-section inciphisa i-torsional deformation ngexesha lokwakhiwa, okwenza ii-beams ze-H zizinze ngakumbi xa zisetyenziswe njengemiqadi ephambili yomthwalo. Ukongezelela, iiflethi zabo ezicakileyo zilula ukudibanisa namanye amacandelo (umzekelo, iibholiti, ii-welds) ngaphandle kokucubungula okuyinkimbinkimbi-oku kunciphisa ixesha lokwakhiwa kwendawo nge-30% xa kuthelekiswa namacandelo ensimbi angaqhelekanga, okubalulekileyo kwiiprojekthi ezikhawulezayo ezifana nezakhiwo zorhwebo kunye neziseko eziphuthumayo.

Ukonakala okuLungileyo kunye noKuxhathisa uMlilo (ngoNyango): Imiqadi ye-H engalungiswanga ithanda ukuba nomhlwa, kodwa emva konyango lomphezulu olufana ne-hot-dip galvanizing okanye i-epoxy coating, inokuxhathisa umhlwa kwindawo efumileyo okanye eselunxwemeni (umz., amaqonga angaphandle konxweme, iindlela eziselunxwemeni). Kwiimeko zobushushu obuphezulu njengeendibano zocweyo zoshishino ezineziko, imiqadi ye-H enganyangekiyo emlilweni (egqutywe ngepeyinti ye-intumescent ye-retardant fire) inokugcina umthamo wokuthwala umthwalo ngaphezu kwemizuzu ye-120 kwimeko yomlilo, ihlangabezana nemigangatho engqongqo yokhuseleko lomlilo.

Iimeko zeSicelo ekujoliswe kuzo: Ukhetho oluLungileyo

Iiprojekthi ezahlukeneyo zokwakha zineemfuno ezahlukeneyo zemiqadi ye-H. Kuphela ngokulungelelanisa iipropathi zemveliso kunye neemfuno zesayithi apho ixabiso labo linokwandiswa. Ezi zilandelayo ziimeko ezintathu zesicelo eziqhelekileyo kunye neendibaniselwano ezicetyiswayo.

IZakhiwo zokuHlala kunye nezoRhwebo eziPhakamileyo: Kwizakhiwo ezinamabali angama-10-30, i-medium gauge H-beams eyenziwe kwi-Q355B yensimbi (H250 × 125 × 6 × 9 ukuya kwi-H350 × 175 × 7 × 11) iyacetyiswa. Amandla abo aphezulu axhasa ubunzima bemigangatho emininzi, ngelixa ubungakanani babo obubambene bugcina indawo yoyilo lwangaphakathi.

Iibhulorho kunye neZakhiwo ezinde: Iibhulorho ezinde (i-spans ≥50 yeemitha) okanye uphahla lwenkundla lufuna i-H-beams ezinkulu, ezinobunzima obukhulu (H400 × 200 × 8 × 13 okanye ngaphezulu).

IZityalo zoShishino kunye neZitora: Izityalo ezinobunzima (ezifana nezityalo zokwenza iimoto) kunye neendawo zokugcina iimpahla ezinkulu zifuna imiqadi ye-H ekwazi ukuxhasa ubunzima bezixhobo okanye ukupakisha imithwalo.
