Ama-node okuxhumanisa i-formwork yensimbi ayizinto ezibalulekile zokudlulisa umthwalo ezivame ukwehluleka ngaphansi kokulayisha okujikelezayo, ukufakwa okungafanele, noma ukuwohloka kwezinto. Ngokusekelwe emibikweni yensimu yobunjiniyela kanye nokuhlaziywa kokuhluleka kwesakhiwo, amaphutha avame kakhulu afaka:
Amamodi Okwehluleka Okuyisisekelo
- Ukucheba Nokukhulula I-Bolt: Ukucindezela okuphezulu kwekhonkrithi eceleni kubangela amandla okusika amabhawodi okuxhuma, okuholela ekuqhekekeni kokusika noma ukukhululeka okuqhubekayo ngenxa yokudlidliza kanye nokujikeleza kokushisa. Ukulahlekelwa ngaphambi kokucindezeleka ngemva kwemijikelezo engu-50-80 kuyinkinga ephindaphindayo ezinhlelweni ezingasetshenziswa kabusha.
- Ukususwa kwe-Weld kanye nokuqhekekaIzindawo ezithintekile ekushiseni (HAZ) ezixhunyanisweni ezihlanganisiwe zithuthukisa imifantu emincane ngaphansi kokucindezeleka okuphindaphindiwe, ikakhulukazi ezindaweni lapho kuhlangana khona ipuleti ne-brace. Ukuqhekeka kokukhathala kuqala ezinzwaneni zokushiswa futhi kusakazeke ngaphansi komthwalo ojikelezayo, ikakhulukazi ezinsimbini ze-Q690+ ngaphandle kokwelashwa kokushisa ngemuva kokushiswa.
- Ukwehluleka Kwebhereri Emigodini YebholitiUkucindezeleka okucindezelwayo okuzungeze imigodi yamabholidi kubangela ukuguguleka kwepulasitiki noma ukuchotshozwa kwepuleti lensimbi, ikakhulukazi kumaphaneli amancane noma lapho ukuhlelwa kwamabholidi ahleliwe kungaklanywanga kahle.
- Ukubopha Ipuleti Lokuxhuma: Amapuleti okuxhuma amancane (≤8 mm) ngaphansi kwesidingo esikhulu abonisa ukugoba okugobile okuseceleni, ikakhulukazi ezinhlelweni ezinde zefomu ezinokuqina okunganele.
- I-Pin kanye ne-Socket WearEzinhlelweni zokushelela noma zokwenyuka, amalunga e-pin-and-socket aguga kakhulu futhi aqhekeke, okunciphisa ukulawula ukujikeleza futhi kubangele ukungalungi kahle.
Izici Ezinikelayo
- Ukukhiqiza Ukubekezelelana: Ukuphambuka kobukhulu obungu-±1.5 mm ekwakhiweni kuholela ekungalingani kahle ngesikhathi sokuhlanganiswa, okubangela izikhathi zokugoba zesibili ezingabalwanga ekwakhiweni.
- Ukugqwala kanye Nokungcola: Izinsalela zekhonkrithi, ukuchayeka emanzini anosawoti, noma ukuhlanza okunganele kusheshisa ukugqwala kwemigodi emicu yebholidi kanye nemithungo yokushisela, kunciphisa amandla okusebenza kahle kwesigaba kanye nomthwalo.
- Isicelo se-Torque esingafaneleAmabholthi angaqiniswanga kahle (ngaphansi kuka-70% wokulayisha kusengaphambili okucacisiwe) ayahluleka ngaphambi kwesikhathi; ukuqinisa ngokweqile kubangela ukuqhekeka kwentambo noma ukuphambuka kwepuleti.
- Ukuqongelela Kokukhathala OkujikelezayoIzinhlelo ezisetshenziswa kabusha ngaphezu kwemijikelezo eyi-100 zibonisa umonakalo oqongelelekayo, kanti amazinga okuhluleka anda kakhulu ngemva kwemijikelezo eyi-150 ngenxa yokukhathala kwezinto ezibonakalayo kanye nokucindezeleka kwepulasitiki oqongelelekayo.
Izindinganiso kanye Nesiqondiso Sokuxilonga
Nakuba kungekho standard elawula kuphela ama-node okuxhumanisa ama-formwork , izindlela zokwehluleka zihambisana ne -Eurocode 3 (EN 1993-1-8) yamajoyinti ensimbi kanye nokugcizelela kwe -ACI 347-22 ekuthembekeni kokuxhumeka ngaphansi kwemithwalo enamandla. Ukuhlolwa kwensimu kuvame ukusebenzisa:
- Ukuhlolwa kwezinhlayiya ze-magnetic (MT) zokuqhekeka kobuso
- Ukuhlolwa kwe-torque wrench yokuqinisekiswa kokulayisha kusengaphambili kwe-bolt
- Ukuskena nge-laser ukuthola ukungalungi >5 mm
