Uyigcina njani iBailey Steel Bridge

Iphaneli yeBailey ngokuqhelekileyo yenziwa ngokuwelda iichords eziphezulu nezisezantsi, iintonga ezithe nkqo, kunye neentonga zediagonal. Kukho zombini amalungu angamadoda nabasetyhini ngaphezu kweentonga eziphezulu kunye nezisezantsi, kunye ne-pestle rack connection pin holes kumalungu. I-chord yepaneli ye-Bailey iqulethwe ngeentsimbi ezimbini ze-Channel 10. Kwi-chord ephantsi, iipleyiti ezininzi zetsimbi ezinemingxuma ejikelezayo zihlala zi-welded. Kwimibhobho ephezulu kunye nesezantsi, imingxuma ye-bolt ixhotyiswe ukuqinisa i-chord kunye ne-double truss connection. Kwi-chord ephezulu, kukho imingxuma emine yebholiti edibeneyo kwisakhelo sokuxhasa. Imingxunya emibini esembindini isetyenziselwa ukudityaniswa kwemiqolo ephindwe kabini okanye emininzi yetrasi enecandelo elifanayo, ngelixa imingxuma emibini kwiziphelo zombini ikuqhagamshelo lwe-inter-node. Xa imiqolo emininzi yeepaneli ze-Bailey ziqeshwe njengemiqadi okanye iikholomu, kuyimfuneko ukuqinisa amajoyina eepaneli ze-Bailey eziphezulu kunye nezantsi kunye nezakhelo zokuxhasa.

Kwi-chord esezantsi, kukho iipleyiti ezi-4 ezinqamlezayo zokuxhasa umnqamlezo, indawo ephezulu ebonelelwe nge-tenon ukulungisa indawo yomnqamlezo kwinqwelomoya, kunye nemingxunya emibini ye-elliptical ibonelelwa kwi-channel yentsimbi ekupheleni intonga yechord esezantsi yokudibanisa i-sway brace. Ibar ethe nkqo yenziwe nge-8 # I-steel, kwaye kukho umngxuma osisikwere kwicala le-chord esezantsi yebar ethe nkqo, esetyenziselwa ukulungiswa kwe-beam ukulungisa umqadi. Izinto zeBeret sheet ziyi-16Mn, kwaye isakhelo ngasinye sinobunzima be-270kg.

1. Khangela ukuba ngaba iphaneli yebhulorho yonakele, ineziphene okanye igqwethekile, kwaye uyibuyisele xa kukho imfuneko.

2. Qwalasela ukuba ngaba iidowels ezahlukeneyo, iibholiti, izixhobo ze-beam kunye ne-sway brace yeepaneli ze-Bailey zidityaniswe ngokufanelekileyo, nokuba kukho umonakalo owenziweyo okanye ukukhulula ukuqinisekisa ukudlula okuzinzile.

3. Khangela ukuba ngaba iphaneli yebhulorho igqabhukile, igogekile okanye ayilingani, kwaye uyibuyisele xa kuyimfuneko.

4. Ukulinganisa ukuphambuka okuphakathi kwe-span yebhuloho ukujonga ukuba iyanda, kwaye izinga lokunyuka kwe-deflection kufuneka lihambelane nokugqoka izikhonkwane kunye nemingxuma yepini.

5. Khangela ukuba isiseko sebhulorho yentsimbi yeBeret sinendawo yokuhlala engalinganiyo, kwaye uyilungelelanise ngokukhawuleza ukuba ifunyenwe.

6. Gcoba igrisi ejikeleze izikhonkwane ukunqanda imvula ukuba ingangeni kwisithuba semingxuma yezikhonkwane, kwaye uthambise yonke imisonto evelileyo yeebholiti ukunqanda umhlwa. Ibhulorho yaseBailey isetyenziswa ngokubanzi kubunjineli bezithuthi. Iphaneli yeBailey inesakhiwo esilula, ukuthuthwa okufanelekileyo, umthamo omkhulu womthwalo, ukutshintshwa okugqwesileyo kunye nokuguquguquka okunamandla.

7. Ngethuba lokugcinwa, injineli kufuneka ihlolisise ngokucophelela amacandelo ahlukeneyo ebhulorho yensimbi ukuqinisekisa ukuba akukho peyinti yepeyinti, i-rust okanye i-deformation kwindawo nganye. Kwindawo enomhlwa, abasebenzi kufuneka bacoce uthuli, ioli, umhlwa kunye nezinto ezahlukeneyo ezingcolileyo kuqala, baze batshize ipeyinti ngokulinganayo kwaye ngokufanelekileyo. Ukuba kukho naziphi na iindawo ezifunyaniswa ukuba zikhubazekile, kufuneka zitshintshwe ukuze kugcinwe ukusetyenziswa okuzinzileyo kwebhuloho yensimbi.
