Simbi H Beam, yakatumidzwa zita rekuti "H"-shaped cross-section, isimbi inoshanda zvakanyanya uye ine hupfumi ine zvakanakira senge yakasimba kubhenda kuramba uye parallel flange nzvimbo. Iwo anoshandiswa zvakanyanya munzvimbo dzakasiyana siyana, kusanganisira kuvaka, mabhiriji, uye kugadzira michina. Pakati peakawanda maH-beam zviyero, H-matanda akatsanangurwa muASTM A992 anomira pachena nekuita kwavo kwakatanhamara.
ASTM A992 H-matanda ndiyo inonyanya kushandiswa simbi yezvivakwa muzvivakwa zveUS, inopa simba repamusoro uye kusimba kwakanyanya. Nesimba shoma regoho re50 ksi (inenge 345 MPa) uye kusimba kwesimba pakati pe65 ne100 ksi (inenge 448 uye 690 MPa), vanogona kutsungirira mitoro inorema uye kuratidza yakanakisa weldability uye seismic kuramba. Izvi zvinoitaASTM A992 H matandazvinhu zvinosarudzwa zvezvirongwa zvakakosha zvakadai sezvivakwa zvepamusoro uye mabhiriji makuru.
Pakati pehukuru hwakasiyana hweASTM A992 H-beam, 6 * 12 uye 12 * 16 saizi ndiyo yakajairika.
6 * 12 Metal H Beam ine yakatetepa flange upamhi uye ine mwero kureba, ichipa yakanakisa ehupfumi uye inoshanda maapplication. Muindasitiri yekuvaka, ivo vanowanzoshandiswa muzvikamu zvezvimiro seyechipiri matanda uye purlins muzvivako zvekugara uye zvekutengesa, zvinobudirira kugovera mitoro yekuvaka uye kuve nechokwadi chekugadzikana kwemaitiro. Muzvidyarwa zvidiki zveindasitiri, 6 * 12 H-matanda zvakare anowanzoshandiswa kutsigira zvivakwa zvedenga uye kusangana nemitoro inotakura zvinodiwa.
12 * 16 Inopisa Yakakungurutswa H Beam inopa akakura-muchinjika-chikamu zviyero uye yakakwirira-yekutakura mutoro. Mukuvaka mabhiriji makuru, anoshanda sematanda ekutanga anotakura mitoro, anotora mitoro yemotokari uye kushushikana kwenzvimbo yechisikigo, kuve nechokwadi chekusimba uye kusimba kwebhiriji. Muzvivakwa zvepamusoro-soro, 12 * 16 H-matanda inowanzoshandiswa munzvimbo dzakakosha dzakadai semachubhu epakati uye mapuranga emapuranga, achipa rubatsiro rwakasimba rwechimiro chose uye kuchidzivirira kubva kune njodzi dzinongoitika dzoga dzakadai semhepo uye kudengenyeka kwenyika. Uyezve, 12 * 16 H-matanda zvakare inoita basa risingadzokerike mumapurojekiti akakura senge hombe maindasitiri emidziyo nheyo uye chiteshi chengarava.
Muchidimbu, ASTM A992 H-matanda, nekuita kwayo kwakanaka uye kwakasiyana siyana hukuru hunoshanda, inoita basa rakakosha mumapurojekiti akasiyana ekuvaka. 6 * 12 uye 12 * 16 H-matanda, ane maitiro avo akasiyana, anosangana nezvinodiwa zvakasiyana-siyana zvemapurojekiti akasiyana-siyana, achityaira kuenderera mberi kwekuvakwa kweinjiniya yemazuva ano.
Zviri pamusoro apa zvinoratidza maitiro eASTM A992 Carbon Steel H Beam, kubva pakuita kusvika pakushandisa. Kana iwe uchida kuwedzera mamwe maratidziro kana mamiriro ekushandisa, ndapota ndizivise.
