Impembelelo yobude be-cantilever ephezulu kumthwalo we-shoring we-disc-lock formwork

I-Rapid Scaffolding (Ubunjineli) Co., Ltd iseke ubuhlakani bobuchule kunye neYunivesithi yaseMpuma ukusukela ngo-2004 kwaye ikwasekwa neqela elinamandla lophando lwenzululwazi lokuthatha uphando olunzulu ngenkqubo echaphazela ukhuseleko lwediski yefomwork. Ubude be-cantilever ephezulu ngumgama ukusuka ebusweni obuphezulu be-U entloko ukuya kwinqanaba eliphezulu le-leja yenkxaso yenkxaso, njengokuba ubude be-cantilever kumfanekiso ongezantsi, obizwa ngokuba yi-cantilever ubude.

Ubude beCantilever buhlala budinga ukuhlengahlengiswa ukuze kuhlangatyezwane nobude beemfuno zoyilo. Njengomgama ukusuka kumgangatho ukuya kweyona disc ikufutshane ye-octagonlock yi-250mm okanye i-325mm (isiseko ikhola ukuya phezulu), ithathela ingqalelo ukuphakama kwentloko ye-U ehlengahlengiswayo, ke ubude be-cantilever bulingana okanye bungaphezulu kwe-300mm ngokubanzi.

Esona sikhundla sibuthathaka sokuqina kwefomu yokutshixa kwidiski kukwimo yenkxaso ejonge phezulu, ukuze sifunde ifuthe lobude be-cantilever kwindawo yokulayisha ezinzileyo yesakhiwo se-scaffold, sithatha i-4 × 4 ubude be-1 inyathelo kunye ne-4 × 4 ubude be-4 Amanqanaba enkqubo yokwakhiwa kwenkxaso njengezinto zophando (inyathelo eliqhelekileyo h = 1500mm), cinga ngokwahlukeneyo ubude besiphelo se-cantilever sibe ngama-300 ~ 1000mm, kwaye wandise uzinzo olungagungqiyo nge-50mm ixesha ngalinye lokubala.

Ngobude be-cantilever obandayo kunye nenkxaso ye-formwork endaweni yoko, ukufuduswa okuphezulu kuyaqhubeka kunyuka, ulwakhiwo lwenkxaso lutshintsha ukusuka ekuguqulweni kokungazinzi ukuya kungazinzi kwendawo ekugqibeni kwekantilever. Imo yokungazinzi iboniswa kulo mzobo ulandelayo:

Iziphumo zokubala zesikhundla sokulayisha esizinzileyo sokugqibela se-4 × 4 yesithuba se-1 kunye ne-4 × 4 ye-4 amanyathelo ama-4 amanyathelo ediski yesakhiwo senkxaso yesakhiwo kunye nobude becandelo le-cantilever kubonisiwe kule theyibhile ilandelayo:

Ukusuka kule tafile, ibonakalise ukuba ubude be-cantilever bunempembelelo enkulu kulwazi oluzinzileyo lokulayisha kwenkxaso yeefom. Umzekelo: i-4X4 span 4 amanyathelo axhasa ulwakhiwo, xa a = 300mm, umthwalo wayo wokulayisha ozinzileyo Pcr = 77.91KN, okanye xa = 1000mm, umthwalo wayo wokulayisha ozinzileyo Pcr = 21.97kN, xa a = 300mm, ehambelana nomthamo wokulayisha wama-27.9% .

Iziphumo zibonisa ukuba ubude be-cantilever bunempembelelo enkulu kulwakhiwo oluzinzileyo lokufaka ulwakhiwo lwenkxaso kulwakhiwo. Ke ngoko, kuyilo lobunjineli kunye nolwakhiwo, ubude becantilever kufuneka bulawulwe ngokungqongqo ukuqinisekisa ukhuseleko lolwakhiwo lwenkxaso kulwakhiwo. Abaqulunqi kufuneka basekwe kumthwalo (ngokuthe nkqo, ngokuthe nkqo) kubungakanani. Kuba ubude cantilever ezinkulu, amanyathelo ulwakhiwo ukunciphisa oxwesileyo Ileda inyathelo ingasetyenziswa ukuphucula ukhuseleko lwesakhiwo formwork inkxaso.
