Umqadi wentsimbi i-H, ebizwa ngegama labo elifana ne-"H", zizinto zentsimbi ezisebenzayo nezingabizi kakhulu ezineenzuzo ezifana nokumelana okunamandla okugoba kunye nemiphezulu yeflange ehambelanayo. Zisetyenziswa kakhulu kwiindawo ezahlukeneyo, kubandakanya ukwakhiwa, iibhulorho, kunye nokuveliswa koomatshini. Phakathi kwemigangatho emininzi ye-H-beam, ii-H-beams ezichazwe kwi-ASTM A992 zibalaseleyo ngokusebenza kwazo okugqwesileyo.
I-ASTM A992 H-beams zezona ntsimbi zesakhiwo ezisetyenziswa kakhulu kwizakhiwo zase-US, zinika amandla aphezulu kunye nokuqina okugqwesileyo. Ngomgangatho ophantsi wemveliso ye-50 ksi (malunga ne-345 MPa) kunye namandla okutsalwa phakathi kwe-65 kunye ne-100 ksi (malunga ne-448 kunye ne-690 MPa), zinokumelana nemithwalo enzima kwaye zibonise ukuwelda okugqwesileyo kunye nokumelana nokushukuma komhlaba. Oku kwenza ukubaImisebe ye-ASTM A992 Hizinto ezikhethwayo kwiiprojekthi ezibalulekileyo ezifana nezakhiwo eziphakamileyo kunye neebhulorho ezinkulu.
Phakathi kobukhulu obahlukeneyo be-ASTM A992 H-beam, ubukhulu obuyi-6*12 kunye no-12*16 zezona zixhaphakileyo.
I-6*12 Metal H Beam inobubanzi obuncinci beflange kunye nokuphakama okuphakathi, okubonelela ngezicelo ezingabizi kakhulu nezisebenzisekayo. Kwishishini lokwakha, zihlala zisetyenziswa kwizinto zokwakha ezifana neebhari zesibini kunye neepurlins kwizakhiwo zokuhlala nezezorhwebo, zabelana ngempumelelo ngemithwalo yezakhiwo kwaye ziqinisekisa uzinzo lwesakhiwo. Kwizityalo ezincinci zoshishino, iibhari ze-6*12 H nazo zihlala zisetyenziselwa ukuxhasa izakhiwo zophahla kunye nokuhlangabezana neemfuno zokuthwala umthwalo.
I-12*16 Hot Rolled H Beam inikezela ngobukhulu obukhulu obunqamlezileyo kunye nomthamo ophezulu wokuthwala umthwalo. Ekwakhiweni kwebhulorho enkulu, isebenza njengeebhari eziphambili ezithwala umthwalo, zifunxa imithwalo yezithuthi kunye noxinzelelo lwendalo, ziqinisekisa ukomelela kunye nokuqina kwebhulorho. Kwizakhiwo eziphakamileyo kakhulu, iibhari ze-12*16 H zihlala zisetyenziswa kwiindawo ezibalulekileyo ezifana neetyhubhu eziphambili kunye neekholamu zesakhelo, zibonelela ngenkxaso enamandla kwisakhiwo sonke kwaye zisikhusela kwiintlekele zemvelo ezifana nomoya kunye neenyikima. Ngaphezu koko, iibhari ze-12*16 H nazo zidlala indima engenakutshintshwa kwiiprojekthi ezinkulu ezifana neziseko zezixhobo zoshishino ezinkulu kunye neetheminali zezibuko.
Ngamafutshane, ii-ASTM A992 H-beams, ezisebenza kakuhle kakhulu kunye nobukhulu obahlukeneyo obusebenzayo, zidlala indima ebalulekileyo kwiiprojekthi ezahlukeneyo zokwakha. Ii-6 * 12 kunye ne-12 * 16 H-beams, ezineempawu zazo ezikhethekileyo, ziyahlangabezana neemfuno ezahlukeneyo zeeprojekthi ezahlukeneyo, ziqhuba uphuhliso oluqhubekayo lolwakhiwo lobunjineli banamhlanje.
Umxholo ongentla ubonisa iimpawu ze-ASTM A992 Carbon Steel H Beam, ukusuka ekusebenzeni ukuya ekusetyenzisweni. Ukuba ungathanda ukongeza ezinye iinkcukacha okanye iimeko zesicelo, nceda undazise.
