Intsimbi enomfanekiso ka-H ihlanganiswe ndawonye

Yintoni i-H Beam?

Umqadi we-Hiyonga imaliIprofayili yentsimbi enomfanekiso we-H, equlathe iwebhu (ipleyiti esembindini ethe nkqo) kunye neeflanges (iipleyiti ezimbini ezinqamlezileyo). Igama layo livela ekubeni ifana nonobumba "H." Yintsimbi esebenza kakuhle kwaye ingabizi kakhulu. Xa ithelekiswa neqhelekileyoUmqadi we-Is, ine-modulus enkulu yecandelo, ubunzima obulula, amandla aphezulu, kunye neempawu ezingcono zoomatshini. Isetyenziswa kakhulu ekwakheni, ekwakheni iibhulorho, nakwimveliso yoomatshini.

Iingenelo zentsimbi enomfanekiso we-H xa kuthelekiswa nezinye iintsimbi

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

Umba wokuthelekisa	Umqadi we-H	Amanye amacandelo entsimbi (umz., i-I-beam, i-channel steel, i-angle steel)
Uyilo oluQhelekileyo	Imile okwe-H ene-flanges ezilinganayo kunye ne-web ebhityileyo; ukusasazwa kwezinto ezifanayo.	I-beam ineeflanges ezinciphileyo; intsimbi yetshaneli/ye-engile ineenxalenye ezingalinganiyo nezingaqhelekanga.
Umthamo Wokuthwala Umthwalo	Amandla aphezulu nge-10-20% ubude kunye nokumelana okungcono kokugoba ecaleni ngenxa yeeflange ezibanzi.	Umthwalo ophantsi; uthambekele ekuxinezelekeni kwiindawo ezithile.
Ukusebenza kakuhle kobunzima	Ikhaphukhaphu nge-8-15% kuneendawo ezifanayo zemveli phantsi komthwalo ofanayo.	Ubunzima obuphezulu, obunyukayo bomzimba obungasasebenziyo kunye nomthwalo wesiseko.
Ukusebenza kakuhle koLwakhiwo	Ukulungiswa okuncinci kwindawo; ukuwelda/ukubopha ngokuthe ngqo kunciphisa umsebenzi nge-30-60%.	Ifuna ukusika/ukuqhawula rhoqo; umthwalo womsebenzi wokuwelda ophezulu kunye nomngcipheko wokukhubazeka.
Ukuqina kunye nokugcinwa	Ukumelana nokugqwala/ukudinwa okwandisiweyo; imijikelo yolondolozo yandiswa ukuya kwiminyaka eli-15 nangaphezulu.	Imijikelo yolondolozo emifutshane (iminyaka esi-8 ukuya kweli-10); iindleko eziphezulu zokugcinwa kwexesha elide.
Ukuguquguquka	Ifumaneka kwiifom ezigoqiweyo (eziqhelekileyo) okanye ezidityanisiweyo (ezenzelwe wena) kwiibhulorho, izakhiwo, njl.njl.	Ukungakwazi ukuzivumelanisa nezimo kwiiprojekthi ezinkulu okanye ezithwala imithwalo enzima.

Ukusetyenziswa kwentsimbi enomfanekiso we-H kubomi bemihla ngemihla

Izakhiwo zenkxaso zeevenkile ezinkulu kunye neevenkile ezinkulu: Iisilingi eziphakamileyo kunye neefreyimu ezithwala umthwalo zemigangatho enemigangatho emininzi kwiindawo ezinkulu zokuthenga zihlala zakhiwa kusetyenziswa ii-H-beams.

Uphahla kunye nezitendi zeenkundla zemidlalo kunye neethiyethaUmzekelo, izitendi zesakhiwo sokuhlala, esinokuthwala amawaka abantu, kunye nophahla olubanzi olugubungela yonke indawo, zixhomekeke kumandla alula kunye nokuthwala umthwalo ee-H-beams.

Izixhasi zophahla kwiimarike zemifuno kunye neemarike zabalimi: I-scaffolding yesinyithi ephezulu kwezinye iimarike zemifuno ezivulekileyo okanye ezivulekileyo kancinci zihlala zisebenzisa ii-H-beams njengeemitha eziphambili.

Iipaseji ezigqithayo nezingaphantsi: Ii-overpasses esizisebenzisa yonke imihla zihlala zine-H-beams njengeebhari ezithwala umthwalo phantsi kwedekhi yebhulorho.

Iifreyimu ezinemigangatho emininzi zeendawo zokupakaKwiindawo zokupaka iimoto ezinemigangatho emininzi kwiindawo zokuhlala okanye kwiindawo zokuthenga ezinkulu, ii-floor slabs kunye neekholamu kumgangatho ngamnye kufuneka zixhase ubunzima bezithuthi, apho amandla aphezulu kunye nokumelana nokugoba kwe-H-beams kuyanceda.

Iipavilion kunye neepaseji kwiindawo zokuhlala: Iindawo ezininzi zokuhlala zineendawo zokuhlala okanye iipavilion kwiindawo zazo zokuzonwabisa, kwaye iifreyimu zezi zakhiwo zihlala zenziwe ngee-H-beams (ingakumbi ezo zinyangwe ngonyango lokulwa nokugqwala).

Izakhelo zezikhululo zokuhambisa inkunkuma: Izitishi zokuhambisa inkunkuma zasezidolophini zifuna isakhiwo esomeleleyo ukuxhasa uphahla nezixhobo. Ukumelana nokugqwala kwentsimbi ye-H-beam (kwezinye iimodeli) kunye nomthamo wokuthwala umthwalo zifanelekile kule ndawo, ukuqinisekisa ukusebenza okuzinzileyo kwesitishi sokuhambisa.

Izibiyeli zesikhululo sokutshaja: Intsimbi ye-H-beam idla ngokusetyenziswa njengesakhelo esisisiseko senkxaso yezikhululo zokutshaja iimoto zombane ezikwicala leendlela okanye kwiindawo zokuhlala. Iyazinzisa isikhululo sokutshaja ngelixa ikhusela kwiingozi zezithuthi kunye nemozulu embi, inika uxolo lwengqondo ngelixa itshaja.

Indlela yophuhliso lwentsimbi enobume obungu-H

Njengoko inkqubo yemveliso ikhula, amandla okuvelisa entshaUmqadi we-Hkulindeleke ukuba iphindwe kabini kwiinyanga ezintandathu ezizayo, nto leyo eyenza ixabiso layo lemarike likhuphisane ngakumbi. Abantu abakwishishini baqikelela ukuba le ntsimbi isebenzayo iya kuba lukhetho oluphambili kwiiprojekthi ezinkulu zeziseko zophuhliso zasekhaya kwiminyaka emithathu ukuya kwemihlanu ezayo, inika isiseko esiqinileyo sezinto zokwakha ezisemgangathweni ophezulu kwilizwe lam.
