Nhau - H-yakaita Simbi: Kuita Kwakanakisa, Kuvakwa Kweakawanda Zvishandiso zveSimbi Backbone

Mundima yekuvaka uye indasitiri yemazuva ano,Kupisa Yakakungurutswa Kabhoni Simbi H Beamyakaita senyeredzi inopenya, nekuita kwayo kwakanakisa uye huwandu hwemashandisirwo, yave chinhu chinofarirwa kune akawanda mapurojekiti makuru.

Iyo yakasarudzika-muchinjika-chikamu chimiro cheH-yakaita simbi inoipa inoshamisira ma mechanical properties. Iyo yakafara uye inofambirana flange uye ukobvu hunonzwisisika hwewebhu hunoita kuti ive yakatanhamara mukutakura mutoro. Kunyangwe iri vertical pressure, kana mhepo yakatwasuka, seismic simba nemimwe mitoro, H-beam simbi inogona kurarama nayo zviri nyore. Iyo data yekuyedza inoratidza kuti pasi pemamiriro akafanana, zvichienzaniswa neakajairwa I-matanda, kutakura kugona kweCarbon Steel H Beaminogona kuwedzerwa neanopfuura 30%, nepo huremu hwayo hunogona kuderedzwa ne20%, iyo inovandudza zvakanyanya kushanda kwekushandisa kwezvinhu.

Nekuda kwekuita kwayo kwakanaka,Welding H Beaminoshandiswa mumhando dzakasiyana-siyana dzekushandisa. Mundima yeindasitiri, kuvakwa kwemafekitari makuru kunenge kusinga patsanurwe kubva kuH-yakaita simbi. Kufanana nemotokari yekugadzira motokari, chimiro chayo chakareba chinoda chimiro chakasimba chekutsigira, H-shaped simbi mbiru uye matanda, izvo zvinogona kutakura zvakachengeteka uremu hwemichina mikuru pamusoro pemiti uye mukati, uye inovimbisa kugadzikana kwenzvimbo yekugadzira. Munzvimbo dzekutengesa, iyo yakavhurika nzvimbo dhizaini yenzvimbo huru dzekutenga ine zvakanyanyisa zvinodikanwa zvekutakura-kuremerwa uye nzvimbo span yezvinhu. Simbi yakaumbwa neH inowana yakakura-span column-yemahara nzvimbo nekuda kweyayo mabhenefiti, ichigadzira yakavhurika uye yakagadzika nzvimbo yekutenga yevatengi.

Muchimiro chesimbi chechivako,Simbi Chimiro H Beamiri kuita basa rinokosha risingatsivike. Kushanda kwayo kwakanaka kwewelding kunoita kuti nzira yekuvaka ishande uye nekukurumidza. Vashandi vekuvaka vanogona kukurumidza kupinza H matanda kuita chivakwa chakasimba, vachipfupisa zvakanyanya kutenderera kwekuvaka. Tichitora chivakwa chehofisi chepamusoro-soro muguta semuenzaniso, iyo yepakati chubhu uye furemu chimiro chakavakwa neH-yakaita simbi haingopi yakasimba yakatwasuka inotakura simba yechivakwa, asi zvakare inogona zvinobudirira kuramba yakachinjika seismic simba nemhepo. Mune dzimwe nzvimbo dzine kudengenyeka kwenyika, zvivakwa zvakavakwa nesimbi yakaita seH zvinoratidza kuita kwekudengenyeka kwenyika kwakanakisa mukudengenyeka kwenyika, uye zvinowedzera kuchengetedzwa kwehupenyu hwevanhu nemidziyo.

Mukuwedzera, simbi yakagadzirwa neH inoitawo basa rinokosha pakuvaka mabhiriji. Ringave zambuko hombe mhiri kwerwizi kana kupfuura muguta, matanda esimbi akagadzirwa nesimbi yakaita seH anogona kumirisana nekuremerwa kwemotokari hombe uye kuyedzwa kwemasimba echisikigo kuti ave nechokwadi chekuchengetedzwa nekugadzikana kwebhiriji.

Kupfupisa, simbi yakaita seH yakasiya mucherechedzo wakadzama muminda yekuvaka uye maindasitiri nekuita kwayo kwakanakisa uye huwandu hwakawanda hwekushandisa. Nekuenderera mberi kwekuenderera mberi kwesainzi uye tekinoroji uye kuwedzera kukura kweinjiniya tekinoroji, H-beam simbi zvirokwazvo ichaita basa rakakosha mune mamwe minda uye inobatsira zvakanyanya mukuvakwa kwevanhu.
