I-H Beam Yensimbi, eqanjwe ngesigaba sayo esinomumo "H", iyinsimbi esebenza kahle kakhulu futhi engabizi kakhulu enezinzuzo ezifana nokumelana okunamandla kokugoba kanye nezindawo ze-flange ezihambisanayo. Zisetshenziswa kabanzi emikhakheni ehlukahlukene, okuhlanganisa ukwakhiwa, amabhuloho, kanye nokukhiqizwa kwemishini. Phakathi kwezindinganiso eziningi ze-H-beam, i-H-beams echazwe ku-ASTM A992 ivelele ngokusebenza kwayo okuvelele.
I-ASTM A992 H-beams yinsimbi yesakhiwo esetshenziswa kakhulu ezakhiweni zase-US, enikeza amandla aphezulu kanye nokuqina okuhle kakhulu. Njengoba inamandla okukhiqiza okungenani angu-50 ksi (cishe angu-345 MPa) kanye namandla okudonsa aphakathi kuka-65 no-100 ksi (cishe angu-448 no-690 MPa), ingamelana nemithwalo esindayo futhi ibonise ukushibilika okuhle kakhulu kanye nokumelana nokuzamazama komhlaba. Lokhu kwenzaImisebe ye-ASTM A992 Hizinto ezikhethwayo zamaphrojekthi abalulekile njengezakhiwo eziphakeme namabhuloho amakhulu.
Phakathi kobukhulu obuhlukahlukene be-ASTM A992 H-beam, osayizi abangu-6*12 no-12*16 yibo abavame kakhulu.
I-6*12 Metal H Beam inobubanzi obuncane be-flange kanye nokuphakama okulingene, okunikeza ukusetshenziswa okuhle kakhulu okungabizi futhi okusebenzayo. Embonini yokwakha, ivame ukusetshenziswa ezingxenyeni zesakhiwo ezifana nemishayo yesibili kanye nama-purlin ezakhiweni zokuhlala nezentengiselwano, yabelana ngempumelelo ngemithwalo yesakhiwo futhi iqinisekisa ukuzinza kwesakhiwo. Ezitshalweni ezincane zezimboni, imishayo engu-6*12 H nayo ivame ukusetshenziselwa ukusekela izakhiwo zophahla nokuhlangabezana nezidingo zokuthwala imithwalo.
I-12*16 Hot Rolled H Beam inikeza ubukhulu obukhulu obuhlanganisa izingxenye kanye nomthamo ophezulu wokuthwala imithwalo. Ekwakhiweni kwebhuloho elikhulu, lisebenza njengemishayo eyinhloko ethwala imithwalo, limunca imithwalo yezimoto kanye nokucindezeleka kwemvelo yemvelo, liqinisekisa amandla nokuqina kwebhuloho. Ezakhiweni eziphakeme kakhulu, imishayo engu-12*16 H ivame ukusetshenziswa ezindaweni ezibalulekile njengemibhobho eyinhloko kanye namakholomu ohlaka, okuhlinzeka ngokusekelwa okuqinile kwesakhiwo sonke futhi kusivikele ezinhlekeleleni zemvelo ezifana nomoya nokuzamazama komhlaba. Ngaphezu kwalokho, imishayo engu-12*16 H nayo idlala indima engenakuphikwa kumaphrojekthi amakhulu njengezisekelo zemishini yezimboni ezinkulu kanye nezindawo zokubeka amachweba.
Ngamafuphi, i-ASTM A992 H-beams, ngokusebenza kwayo okuhle kakhulu kanye nobukhulu obuhlukahlukene obusebenzayo, idlala indima ebalulekile kumaphrojekthi ahlukahlukene okwakha. I-6 * 12 kanye ne-12 * 16 H-beams, enezici zayo ezihlukile, ihlangabezana nezidingo ezahlukahlukene zamaphrojekthi ahlukahlukene, iqhuba intuthuko eqhubekayo yokwakha ubunjiniyela besimanje.
Okuqukethwe okungenhla kubonisa izici ze-ASTM A992 Carbon Steel H Beam, kusukela ekusebenzeni kuya ekusetshenzisweni. Uma ungathanda ukwengeza ezinye izici noma izimo zohlelo lokusebenza, ngicela ungazise.
