Insimbi H Beam, eziqanjwe ngegama eliphambanayo elinomumo othi "H", ziyinsimbi esebenza kahle kakhulu futhi eyongayo enezinzuzo ezifana nokumelana nokugoba okuqinile kanye nezindawo ze-flange ezihambisanayo. Asetshenziswa kakhulu emikhakheni ehlukahlukene, okuhlanganisa ukwakhiwa, amabhuloho, kanye nokukhiqizwa kwemishini. Phakathi kwamazinga amaningi we-H-beam, imishayo ye-H ecaciswe ku-ASTM A992 igqama ngokusebenza kwayo okuvelele.
I-ASTM A992 H-imishayo iyinsimbi yesakhiwo esetshenziswa kakhulu ezakhiweni zase-US, enikeza amandla aphezulu kanye nokuqina okuhle kakhulu. Ngamandla amancane okukhiqiza angu-50 ksi (cishe ama-MPa angu-345) namandla aqinile phakathi kuka-65 no-100 ksi (cishe ama-MPa angu-448 nama-690), angakwazi ukumelana nemithwalo esindayo futhi abonise ukushisela okuhle kakhulu kanye nokumelana nokuzamazama komhlaba. Lokhu kwenzaI-ASTM A992 H imishayoizinto ezikhethwayo zamaphrojekthi abalulekile njengezakhiwo eziphakeme kanye namabhuloho amakhulu.
Phakathi kosayizi abahlukahlukene 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 obuncane nobude obumaphakathi, ehlinzeka ngezinhlelo zokusebenza ezingcono kakhulu ezingokongayo nezisebenzayo. Embonini yezokwakha, zivame ukusetshenziswa ezingxenyeni zesakhiwo ezifana nemishayo yesibili kanye nama-purlins ezakhiweni zokuhlala nezohwebo, ukwabelana ngokuphumelelayo ngemithwalo yokwakha nokuqinisekisa ukuzinza kwesakhiwo. Ezitshalweni ezincane zezimboni, i-6 * 12 H-imishayo nayo ivame ukusetshenziselwa ukusekela izakhiwo zophahla futhi ihlangabezane nezidingo zokuthwala umthwalo.
12*16 I-Hot Rolled H Beam inikeza ubukhulu bezingxenye eziphambene namandla aphezulu okuthwala. Ekwakhiweni kwamabhuloho amakhulu, asebenza njengemishayo ethwala imithwalo eyinhloko, emunca imithwalo yezimoto kanye nokucindezeleka kwendawo ezungezile, okuqinisekisa amandla nokuqina kwebhuloho. Ezakhiweni eziphakeme kakhulu, i-12 * 16 H-imishayo ivame ukusetshenziswa ezindaweni ezibalulekile ezifana namashubhu ayisisekelo namakholomu ozimele, ehlinzeka ngokusekela okuqinile kuso sonke isakhiwo futhi isivikele ezinhlekeleleni zemvelo ezifana nomoya nokuzamazama komhlaba. Ngaphezu kwalokho, imishayo engu-12*16 H nayo idlala indima engenakushintshwa kumaphrojekthi amakhulu njengezisekelo ezinkulu zemishini yezimboni namatheminali echweba.
Kafushane, imishayo ye-ASTM A992 H, ngokusebenza kwayo okuhle kakhulu kanye nosayizi abahlukahlukene abasebenzayo, idlala indima ebalulekile kumaphrojekthi ahlukahlukene wokwakha. I-6 * 12 ne-12 * 16 H-imishayo, enezici zayo eziyingqayizivele, ihlangabezana nezidingo ezihlukahlukene zamaphrojekthi ahlukahlukene, ukushayela ukuthuthukiswa okuqhubekayo kokwakhiwa kobunjiniyela besimanje.
Okuqukethwe okungenhla kubonisa izici ze-ASTM A992 Carbon Steel H Beam, kusukela ekusebenzeni kuya ekusetshenzisweni. Uma ungathanda ukwengeza ezinye izicaciso noma izimo zohlelo, ngicela ungazise.
