Insimbi emise okwe-H ehlanganiswe ndawonye

Yini i-H Beam?

I-H-beamkuyinto ukongaIphrofayili yensimbi emise okwe-H, ehlanganisa iwebhu (ipuleti elime mpo elimaphakathi) nama-flange (amapuleti amabili aguquguqukayo). Igama layo lisukela ekufaneni kwayo nohlamvu "H." Kuyinto esebenza kahle kakhulu futhi iyonga impahla yensimbi. Uma kuqhathaniswa nokujwayelekileI-beams, ine-modulus yesigaba enkudlwana, isisindo esilula, amandla aphezulu, kanye nezakhiwo ezingcono zomshini. Isetshenziswa kabanzi ekwakheni, ekwakhiweni kwamabhuloho, nasekukhiqizeni imishini.

Izinzuzo Zensimbi Emise Okungu-H Iqhathaniswa Nenye Insimbi

Ukuqhathanisa phakathi kwe-H-beam ne-I-beam

Isici sokuqhathanisa	I-H-Beam	Ezinye Izingxenye Zensimbi (isb., I-I-beam, insimbi yesiteshi, insimbi ye-engeli)
I-Cross-Section Design	Okumise okwe-H ngama-flange ahambisanayo kanye newebhu encane; ukusatshalaliswa kwezinto ezifanayo.	I-I-beam inama-flange acijile; insimbi/insimbi ye-engeli inezigaba ezingajwayelekile, ezingalingani.
Ikhono Lokuthwala	Amandla e-longitudinal aphezulu angu-10-20% kanye nokumelana kangcono nokugoba kwe-lateral ngenxa yama-flange abanzi.	Umthamo womthwalo wonke ophansi; othambekele ekugxilweni kwengcindezi ezindaweni ezithile.
Ukuphumelela Kwesisindo	Ilula ngo-8-15% kunezigaba zendabuko ezifanayo ngaphansi komthwalo ofanayo.	Kusinda, kukhuphula isisindo sesakhiwo esifile kanye nomthwalo wesisekelo.
Ukusebenza Ngekhono Lokwakha	Ukucubungula okuncane endaweni; i-welding/bolting eqondile inciphisa umsebenzi ngo-30-60%.	Idinga ukusika/ukuhlanganisa njalo; umsebenzi wokushisela ophezulu kanye nobungozi besici.
Ukuqina Nokugcinwa	Ukumelana nokugqwala/ukukhathala okuthuthukisiwe; imijikelezo yokunakekela inwebelwe iminyaka eyi-15+.	Imijikelezo yesondlo emifushane (iminyaka engu-8-10); izindleko eziphezulu zokugcina isikhathi eside.
Ukuguquguquka	Itholakala ngamafomu agoqiwe (ajwayelekile) noma ashiselwe (ngokwesiko) amabhuloho, izakhiwo, njll.	Ukuzivumelanisa nezimo okulinganiselwe kumaphrojekthi amakhulu noma anomthwalo osindayo.

Ukusetshenziswa kwensimbi emise okwe-H ekuphileni kwansuku zonke

Izakhiwo zokusekela zezitolo ezinkulu nezitolo ezinkulu: Uphahla oluphezulu kanye namafreyimu athwala imithwalo ephansi elinezitezi eziningi enxanxatheleni yezitolo ezinkulu kuvame ukwakhiwa kusetshenziswa ama-H-beam.

Uphahla kanye nezinkundla zemidlalo kanye nethiyetha: Isibonelo, izitendi zesakhiwo sokuhlala, ezingahlalisa izinkulungwane zabantu, kanye nophahla olubanzi olumboza yonke indawo, luncike kumthamo ongasindi kanye nomthwalo wokuthwala wama-H-beam.

Izisekelo zophahla ezimakethe zemifino kanye nezimakethe zabalimi: I-scaffolding yensimbi phezulu kwezinye izimakethe zemifino evulekile noma evulekile ngokuvamile isebenzisa imishayo engu-H njengemishayo eyinhloko.

Amaphasi angaphezulu nangaphansi: Izindawo ezidlula ngaphezulu esizisebenzisa nsuku zonke zivame ukuba nemishayo engu-H njengemishayo ethwala imithwalo ngaphansi kwedekhi yebhuloho.

Amafreyimu anezitezi eziningi ezindaweni zokupaka: Ezindaweni zokupaka ezinezitezi eziningi ezindaweni zokuhlala noma ezinxanxatheleni zezitolo, ama-slabs aphansi namakholomu esitezi ngasinye adinga ukusekela isisindo sezimoto, lapho amandla aphezulu kanye nokumelana nokugoba kwe-H-beams kuza kahle.

Ama-Pavilions namaphasishi emiphakathini yokuhlala: Imiphakathi eminingi ehlala abantu inamapheliyade noma amaphasishi ezindaweni zayo zokungcebeleka, futhi amafreyimu alezi zindawo ngokuvamile enziwa ngama-H-beam (ikakhulukazi lawo alashwe ngokunqanda ukubola).

Amafreyimu eziteshi zokudlulisa imfucuza: Iziteshi zokuthutha imfucuza yasemadolobheni zidinga isakhiwo esiqinile sokusekela uphahla kanye nemishini. Ukumelana nokugqwala kwe-H-beam steel (kwamanye amamodeli) kanye nomthamo wokuthwala umthwalo kufanelekile kule ndawo, kuqinisekisa ukusebenza okuzinzile kwesiteshi sokudlulisa.

Abakaki besiteshi sokushaja: Insimbi ye-H-beam ivame ukusetshenziswa njengohlaka oluyisisekelo lokusekela iziteshi zokushaja izimoto zikagesi eziseceleni komgwaqo noma ezindaweni zokuhlala. Isimamisa isiteshi sokushaja kuyilapho isivikela ekushayisaneni kwezimoto nesimo sezulu esingesihle, inikeza ukuthula kwengqondo ngenkathi ishaja.

Umkhuba wokuthuthuka wensimbi emise okwe-H

Njengoba inqubo yokukhiqiza ikhula, amandla okukhiqiza amashaHleyakulindeleke ukuthi iphindeke kabili phakathi nezinyanga eziyisithupha ezizayo, okwenza intengo yayo yemakethe ikwazi ukuncintisana nakakhulu. Abangaphakathi embonini babikezela ukuthi le nsimbi esebenza kahle kakhulu iyoba inketho evamile kumaphrojekthi amakhulu wengqalasizinda yasekhaya phakathi neminyaka emithathu kuya kwemihlanu ezayo, okuhlinzekela isisekelo esiqinile sempahla yokuthuthukisa izinga eliphezulu lokwakhiwa kwengqalasizinda yezwe lami.
