Kuyini i-H Beam?
Imisebe ye-HAmaphrofayili awongayo, asebenza kahle kakhulu anesigaba esifana nohlamvu "H." Izici zawo eziyinhloko zifaka phakathi ukusatshalaliswa kwendawo enqamulayo okulungiselelwe, isilinganiso samandla kuya kwesisindo esifanele, kanye nezingxenye ezine-engeli yesokudla. Lezi zingxenye zinikeza ukumelana kokugoba okuqondiswe ngezindlela eziningi, ukulula kokwakhiwa, ukwakhiwa okulula (15%-30% okulula kunezakhiwo zensimbi zendabuko), kanye nokonga izindleko. Uma kuqhathaniswa nezinsimbi ze-I ezivamile (izinsimbi ze-I), izinsimbi ze-H zinezingqimba ezibanzi, ukuqina okukhulu kwezinhlangothi, kanye nokumelana kokugoba okuthuthukisiwe cishe ngo-5%-10%. Ukwakheka kwazo kwe-flange ehambisanayo kwenza kube lula ukuxhumana nokufakwa. Zisetshenziswa kabanzi ezisetshenziswayo ezisindayo njengezakhiwo ezinkulu (njengezimboni nezakhiwo eziphakeme), amabhuloho, imikhumbi, kanye nezisekelo zokuphakamisa imishini nemishini, okuthuthukisa kakhulu ukuzinza kwesakhiwo nokunciphisa ukusetshenziswa kwezinto.
Izinzuzo ze-H-beam
1. Izakhiwo Ezinhle Kakhulu Zemishini
Amandla Okugobeka Okuqinile: Ama-flange abanzi namakhulu (angaphezu kokuphindwe ka-1.3 kune-I-beams) ahlinzeka ngomzuzu omkhulu we-inertia, okuthuthukisa ukusebenza kwe-flexural ngo-10%-30%, okwenza kube kuhle kakhulu ezakhiweni ezinde.
Ukuzinza Kokucindezela Kwe-Biaxial: Ama-flange aqonde ngqo kuwebhu, okuholela ekuqineni okuphezulu kwe-lateral kanye nokumelana okuphezulu kwe-torsional kanye ne-rollImishayo ye-I.
Ukusatshalaliswa Kokucindezeleka Okufanayo: Ukushintshashintsha okushelelayo kwezingxenye ezinqamulayo kunciphisa ukugxilisa ingqondo ekucindezelekeni futhi kwandise isikhathi sokukhathala.
2. Ilula futhi iyonga
Isilinganiso Esiphezulu Samandla-kuya-Esisindweni: Silula ngo-15%-30% kunemisebe ye-I yendabuko enomthamo ofanayo wokuthwala umthwalo, okunciphisa isisindo sesakhiwo.
Ukonga Izinto: Ukusetshenziswa kwesisekelo sikakhonkolo okuncishisiwe kunciphisa izindleko zokwakha ngo-10%-20%.
Izindleko Eziphansi Zokuthutha Nokufaka: Izingxenye ezijwayelekile zinciphisa ukusika nokushisela endaweni.
3. Ukwakhiwa Okulula Nokusebenza Kahle
Izindawo ze-flange ezihambisanayo zenza kube lula ukuxhumana ngqo nezinye izingxenye (amapuleti ensimbi, amabhawodi), okwandisa isivinini sokwakha ngo-20%-40%.
Amajoyinti Alula: Nciphisa amajoyinti ayinkimbinkimbi, uqinise isakhiwo, futhi unciphise isikhathi sokwakha.
Imininingwane Ejwayelekile: Izindinganiso ezamukelwa emhlabeni wonke njenge-Chinese National Standard (GB/T 11263), i-Japanese Standard (JIS), kanye ne-American Standard (ASTM A6) ziqinisekisa ukuthengwa okulula kanye nokuzivumelanisa nezimo.
4. Uhla Olubanzi Lwezicelo
Ukwakhiwa Okukhulu: Amafektri, izakhiwo eziphakemeizakhiwo zensimbi(njengengxenye eyinhloko yeShanghai Tower), kanye nezindawo ezinkulu (njengesisekelo se-Bird's Nest truss).
Amabhuloho kanye Nezokuthutha: Amabhuloho esitimela kanye nemigwaqo emikhulu (enezisekeli zebhokisi elide).
Imishini Yezimboni: Imishayo ye-chassis yemishini esindayo kanye ne-port crane track.
Ingqalasizinda Yamandla: Izinsika zezitshalo zikagesi kanye namamojula epulatifomu kawoyela.
5. Ukusimama Kwemvelo
Ingasetshenziswa Kabusha ngo-100%: Amanani aphezulu okusetshenziswa kabusha kwensimbi anciphisa imfucuza yokwakha.
Ukusetshenziswa Kwekhonkrithi Okuncishisiwe: Kunciphisa ukukhishwa kwekhabhoni (ithani ngalinye lensimbi elithathelwe indawo yikhonkrithi lisindisa amathani ayi-1.2 e-CO₂).
Ukusetshenziswa kwe-H Beam
Ukusetshenziswa okuvame kakhulu kwe-Ifektri ye-H Beamszenzelwe amapulatifomu, amabhuloho, ukwakha imikhumbi kanye nedokodo. Ngenkathi i-I Beams ivame ukusetshenziswa ezakhiweni zezentengiselwano ezivamile noma ezinye izinhlelo zokusebenza ezilula.
Kusukela ezikhundleni eziphakeme kakhulu kuya kwingqalasizinda yomphakathi, kusukela embonini esindayo kuya kumandla aluhlaza, imisebe ye-H isibe yinto yokwakha engenakuphindwa yobunjiniyela besimanje.Izinkampani ze-H beam zaseShayina, imininingwane kumele ifaniswe ngokusekelwe emthwalweni, ubude, kanye nendawo yokugqwala (isibonelo, amaphrojekthi asogwini adinga insimbi egugulekayo i-Q355NH) ukuze andise ukuphepha kwawo kanye nenani lawo lezomnotho.
