Imakethe yomhlaba wonke ye-H beam kulindeleke ukuthi ifakaze ukukhula okuphawulekayo eminyakeni ezayo, ikhuthazwa ukwanda kwesidingo emikhakheni yezokwakha kanye nengqalasizinda.I-H beam, eyaziwa nangokuthi i-H-section noma i-wide flange beam, iwumkhiqizo wensimbi wesakhiwo osetshenziswa kabanzi ekwakhiweni kwezakhiwo, amabhuloho, nezinye izakhiwo ezinkulu.
Ngokombiko wakamuva wocwaningo lwemakethe, isidingo se-H beam kulindeleke ukuthi sikhule ngesilinganiso sokukhula sonyaka esiyinhlanganisela (CAGR) esingaphezu kuka-6% kusukela ngo-2021 kuya ku-2026. Lokhu kukhula kungabangwa ngenxa yenani elikhulayo lamaphrojekthi wokwakha emhlabeni wonke, ikakhulukazi emazweni asathuthuka njengeChina, India, namazwe aseNingizimu-mpumalanga ye-Asia.Ukwakhiwa kwezakhiwo ezintsha zokuhlala nezokuhwebelana, kanye nokulungiswa kanye nokwandiswa kwengqalasizinda ekhona, kuqhuba isidingo se-H beam kulezi zifunda.
Esinye sezici ezibalulekile ekukhuleni kwemakethe ye-H beam ukwanda kokwamukelwa kwensimbi njengento yokwakha.Insimbi inikeza izinzuzo ezimbalwa kuzinto zokwakha zendabuko ezifana nokhonkolo nokhuni, okuhlanganisa isilinganiso esiphezulu samandla nesisindo, ukuqina, kanye nokusebenziseka kabusha.Lezi zakhiwo zenza i-H ibe yinketho ekhangayo kubakhi nosonkontileka abafuna ukwakha izakhiwo eziqinile nezisebenza kahle.
Ngaphezu kwalokho, ukuguquguquka kwe-H beam kuyenza ilungele uhla olubanzi lwezinhlelo zokusebenza embonini yezokwakha.I-design yayo ebanzi ye-flange inikeza amakhono amahle kakhulu okuthwala imithwalo, okwenza ifanelekele ukusekela imithwalo esindayo ezakhiweni ezinkulu namabhuloho.Ukwengeza, uthango lwe-H lungenziwa kalula futhi lwenziwe ngezifiso ukuze luhlangabezane nezidingo ezithile zephrojekthi, lunikeze ukuguquguquka okuguquguqukayo kubadwebi bezakhiwo nonjiniyela ekuklameni izakhiwo eziyingqayizivele nezisha.
Ngaphezu kokusetshenziswa kwayo ekwakhiweni, i-H beam iphinde ithole izinhlelo zokusebenza kwezinye izimboni ezinjengokukhiqiza nezimoto.Umkhakha wezimoto, ikakhulukazi, ushayela isidingo se-H beam njengoba uya ngokuya usetshenziswa ekukhiqizeni i-chassis yezimoto namafreyimu.Amandla aphezulu kanye nokuqina kwe-H beam kuyenza ibe into efanelekile yokuqinisekisa ubuqotho besakhiwo nokuphepha kwezimoto.
Ngaphandle kokubuka okuhle kwemakethe ye-H beam, kunezinselelo ezithile ezingaba nomthelela ekukhuleni kwayo.Ukushintshashintsha kwezintengo zempahla yokusetshenziswa, ikakhulukazi insimbi, kungase kuthinte izindleko zokukhiqiza eziphelele kanye nentengo yemikhiqizo ye-H yensimbi.Ukwengeza, ukukhathazeka kwemvelo okuhlobene nokukhiqizwa kwensimbi, okufana nokukhishwa kwekhabhoni kanye nokusetshenziswa kwamandla, kungase kube nomthelela esidingweni semikhiqizo yensimbi okuhlanganisa ne-H.
Ukuze kubhekwane nalezi zinselelo, abakhiqizi baya ngokuya betshala imali ekuthuthukisweni kwezobuchwepheshe kanye nezinqubo ezintsha zokuthuthukisa ukusebenza kahle nokusimama kokukhiqizwa kwe-H.Lokhu kuhlanganisa ukwamukelwa kwamasu okukhiqiza athuthukile kanye nokusetshenziswa kwensimbi egaywe kabusha njengento eluhlaza, engasiza ekunciphiseni umthelela wemvelo wokukhiqizwa kwe-H.
Sekukonke, imakethe ye-H beam ilungele ukukhula okuqinile eminyakeni ezayo, iqhutshwa ukwanda kwesidingo sensimbi kumaphrojekthi wokwakha kanye nengqalasizinda.Ngokugxila okuqhubekayo ekuthuthukisweni okusimeme kanye nezindlela ezintsha zokukhiqiza, imboni ye-H beam kulindeleke ukuthi iqhubeke nokuvela ukuze ihlangabezane nezidingo eziguqukayo zemakethe yezokwakha yomhlaba.
