Yintoni i-H Beam?

H-umqadiluqoqoshoIprofayile yentsimbi emile H, equka iwebhu (iplate embindini ethe nkqo) kunye neeflanges (amacwecwe amabini anqamlezayo). Igama layo livela ekufaneni kwayo neleta "H." Yimpahla yentsimbi esebenza kakhulu kwaye inoqoqosho. Xa kuthelekiswa nesiqheloI-beams, inemodyuli yecandelo elikhulu, ubunzima obulula, amandla aphezulu, kunye neempawu ezingcono zoomatshini. Isetyenziswa ngokubanzi kulwakhiwo, ulwakhiwo lwebhulorho, kunye nokwenziwa koomatshini.

Izinto eziluncedo zentsimbi emile okwe-H xa ithelekiswa nenye intsimbi

Ukuthelekisa phakathi kwe-H-beam kunye ne-I-beam

Inkalo yokuthelekisa	H-Beam	Amanye aMacandelo eNsimbi (umzekelo, i-I-beam, intsimbi yesitishi, intsimbi ye-engile)
Uyilo lweCandelo elinqamlezileyo	I-H ene-flanges ehambelanayo kunye newebhu encinci; ukuhanjiswa kwezinto ezifanayo.	I-I-beam ineeflange ezithe kratya; itshaneli / intsimbi ye-angle inamacandelo angaqhelekanga, asymmetric.
Umthwalo wokuthwala umthamo	I-10-20% ephezulu yamandla e-longitudinal kunye nokumelana nokugoba okungcono kwecala ngenxa yeeflange ezibanzi.	Umthamo ophantsi womthwalo wonke; utyekele ekugxininiseni uxinzelelo kwiindawo ezithile.
Ubuchule bobunzima	I-8-15% ilula kunamacandelo emveli alinganayo phantsi komthwalo ofanayo.	Ubunzima, ukwandisa ubunzima bokufa kunye nomthwalo wesiseko.
Ubuchule bokwakha	Ukusetyenzwa okuncinci kwisiza; ukuwelda ngqo / bolting kunciphisa umsebenzi 30-60%.	Ifuna ukusika rhoqo / ukudityaniswa; umsebenzi wokuwelda ophezulu kunye nomngcipheko wesiphene.
Ukuqina kunye noLondolozo	Ukomelezwa komhlwa/ukumelana nokudinwa; imijikelo yolondolozo yandiswe ukuya kwiminyaka eyi-15+.	Imijikelo emifutshane yokugcina (iminyaka eyi-8-10); iindleko eziphezulu zokugcina ixesha elide.
Ukuguquguquka	Ifumaneka kwi-rolled (standard) okanye i-welded (custom) iifom zeebhulorho, izakhiwo, njl.	Ukulungelelaniswa okulinganiselweyo kwiiprojekthi ezinkulu okanye ezinomthwalo onzima.

Ukusetyenziswa kwentsimbi emise okwe-H kubomi bemihla ngemihla

Iziseko zenkxaso kudederhu lweevenkile kunye neevenkile ezinkulu: Iisilingi eziphakamileyo kunye neefreyimu ezithwele imithwalo yemigangatho emininzi kudederhu lweevenkile ezinkulu zihlala zakhiwe kusetyenziswa imiqadi ye-H.

Uphahla kunye neendawo zokumisa amabala emidlalo kunye neethiyetha: Umzekelo, iindawo zokuma zesakhiwo sokuhlala, ezinokuthi zihlalise amawaka abantu, kunye nophahla olubanzi olugubungela yonke indawo, luxhomekeke kubunzima obulula kunye nomthwalo wokuthwala i-H-beams.

Ukuxhasa uphahla kwiimarike zemifuno kunye neemarike zamafama: I-scaffolding yesinyithi phezulu kwezinye iimarike zemifuno ezivulekileyo okanye ezivulekileyo zihlala zisebenzisa imiqadi ye-H njengeyona miqadi.

Iindlela zokuwela ngaphezulu nangaphantsi: Iindlela ezidlulayo esizisebenzisa yonke imihla zihlala zinemiqadi ye-H njengemiqadi ethwala imithwalo ephantsi komgangatho webhulorho.

Iifreyimu ezinamabali amaninzi kwiindawo zokupaka: Kwiindawo zokupaka iindawo ezininzi zokupaka kwiindawo zokuhlala okanye kwiindawo zokuthenga, i-slabs yomgangatho kunye neentsika kumgangatho ngamnye kufuneka zixhase ubunzima bezithuthi, apho amandla aphezulu kunye nokugoba ukugoba kwe-H-beams kuza ngokufanelekileyo.

Iipaviyoni kunye neepaseji kwiindawo zokuhlala: Uninzi lweendawo zokuhlala zineepaviyoni okanye iipaseji kwiindawo zabo zokuzonwabisa, kwaye iifreyimu zezi zakhiwo zihlala zenziwe nge-H-beams (ingakumbi ezo ziye zanyangwa ngonyango lokunqanda ukubola).

Izakhelo zesikhululo sokudluliselwa kwenkunkuma: Izikhululo zokuthutha inkunkuma yasezidolophini zifuna isakhiwo esomeleleyo ukuxhasa uphahla kunye nezixhobo. I-H-beam yentsimbi ye-corrosion resistance (kweminye imizekelo) kunye nomthamo wokuthwala umthwalo ufanelekile kule ndawo, uqinisekisa ukusebenza okuzinzile kwesikhululo sokudlulisa.

Izibiyeli zesikhululo sokutshaja: Intsimbi ye-H-beam isoloko isetyenziswa njengesiseko sokuxhasa izikhululo zombane zombane ezibekwe kwiindlela okanye kwiindawo zokuhlala. Izinzisa isikhululo sokutshaja ngelixa ikhusela kwiinqwelomoya kunye nemozulu embi, inika uxolo lwengqondo ngelixa ihlawulisa.

Indlela yophuhliso yentsimbi emile okwe-H

Njengoko inkqubo yemveliso ikhula, amandla emveliso entshaH umqakulindeleke ukuba iphindeke kabini phakathi kweenyanga ezintandathu ezizayo, nto leyo eyenza ixabiso layo lemarike likhuphisane nangakumbi. Abantu bangaphakathi kushishino baqikelela ukuba le ntsimbi ikumgangatho ophezulu iya kuba yeyona nto ikhethwayo kwiiprojekthi ezinkulu zeziseko ezingundoqo zasekhaya kwisithuba seminyaka emithathu ukuya kwemihlanu ezayo, ibonelela ngesiseko esiluqilima semathiriyeli sophuhliso olukumgangatho ophezulu wolwakhiwo lweziseko ezingundoqo zelizwe lam.
