Intsimbi H Beam, ebizwa ngokuba yi-"H"-shaped cross-section, zizixhobo zentsimbi ezisebenza kakuhle kunye nezongayo ezineengenelo ezifana nokumelana nokugoba okuqinileyo kunye nomphezulu weflange ohambelanayo. Zisetyenziswa kakhulu kwiinkalo ezahlukeneyo, kubandakanya ukwakhiwa, iibhulorho, kunye nokuveliswa koomatshini. Phakathi kwemigangatho emininzi ye-H-beam, imiqadi ye-H echazwe kwi-ASTM A992 ibalasele ngomsebenzi wayo obalaseleyo.
Imiqadi ye-ASTM A992 H zezona zixhaphakileyo zisetyenziswa kwizakhiwo zentsimbi kwizakhiwo zase-US, ezinika amandla aphezulu kunye nokuqina okugqwesileyo. Ngomlinganiselo omncinci wamandla esivuno se-50 ksi (malunga ne-345 MPa) kunye namandla okuqina phakathi kwe-65 kunye ne-100 ksi (malunga ne-448 kunye ne-690 MPa), banokumelana nemithwalo enzima kwaye babonise i-weldability egqwesileyo kunye nokuxhathisa kwe-seismic. Oku kwenzaImiqadi ye-ASTM A992 Hizinto ezikhethiweyo kwiiprojekthi ezibalulekileyo ezifana nezakhiwo eziphakamileyo kunye namabhuloho amakhulu.
Phakathi kobukhulu obuhlukeneyo be-ASTM A992 H-beam, i-6 * 12 kunye ne-12 * 16 ubukhulu bezona ziqhelekileyo.
I-6 * 12 ye-Metal H I-Beam inobubanzi obuncinci be-flange kunye nobude obuphakathi, inika usetyenziso oluhle kakhulu lwezoqoqosho kunye nokusebenza. Kwishishini lokwakha, zihlala zisetyenziselwa kumacandelo ezakhiwo ezifana nemigangatho yesibini kunye ne-purlins kwizakhiwo zokuhlala kunye nezorhwebo, ukwabelana ngokufanelekileyo kwimithwalo yokwakha kunye nokuqinisekisa ukuzinza kwesakhiwo. Kwizityalo ezincinci zoshishino, ii-6 * 12 ze-H-beams nazo zihlala zisetyenziselwa ukuxhasa izakhiwo zephahla kunye nokuhlangabezana neemfuno zomthwalo.
I-12 * 16 i-Hot Rolled H Beam inikezela ngemilinganiselo emikhulu ye-cross-sectional kunye nomthamo ophezulu wokuthwala umthwalo. Kulwakhiwo lwebhulorho enkulu, zisebenza njengemiqadi ephambili yokuthwala imithwalo, ukufunxa imithwalo yezithuthi kunye noxinzelelo lwendalo esingqongileyo, iqinisekisa ukomelela kwebhulorho kunye nokuqina. Kwizakhiwo eziphakamileyo eziphakamileyo, i-12 * 16 H-beams idla ngokusetyenziswa kwiindawo eziphambili ezifana neetyhubhu eziphambili kunye neentsika zesakhelo, ukubonelela ngenkxaso eqinile kwisakhiwo sonke kunye nokukhusela kwiintlekele zendalo ezifana nomoya kunye neenyikima. Ngaphaya koko, i-12*16 H-beams nayo idlala indima engenakuphinda ithathelwe indawo kwiiprojekthi ezinkulu ezifana neziseko zezixhobo zemizi-mveliso ezinkulu kunye neetheminali zezibuko.
Ngamafutshane, imiqadi ye-ASTM A992 H, ngokusebenza kwayo okugqwesileyo kunye neentlobo ezahlukeneyo zobukhulu obusebenzayo, idlala indima ebalulekileyo kwiiprojekthi ezahlukeneyo zokwakha. I-6 * 12 kunye ne-12 * 16 i-H-beams, eneempawu zabo ezizodwa, ihlangabezana neemfuno ezahlukeneyo zeeprojekthi ezahlukeneyo, ukuqhuba uphuhliso oluqhubekayo lokwakhiwa kobunjineli banamhlanje.
Umxholo ongentla ubonisa iimpawu ze-ASTM A992 Carbon Steel H Beam, ukusuka ekusebenzeni ukuya kwisicelo. Ukuba ungathanda ukongeza ezinye iinkcukacha okanye iimeko zesicelo, nceda undazise.
