Rapid Scaffolding (Engineering) Co., Ltd eguzobewo usoro mmekọrịta ya na Mahadum Ndịda Ebe Ọwụwa Anyanwụ ebe 2004 ma guzobekwa otu ìgwè ndị ọkà mmụta sayensị siri ike iji nyochaa usoro nyocha miri emi maka emetụta mkpọchi disk na-akwado ihe nchekwa. Ogologo nke cantilever bụ ebe dị anya site na elu ihu nke mgbanwe U isi na akwa kachasị elu nke nkwado nkwado, dị ka ogologo cantilever n'ogo dị n'okpuru, nke a na-akpọ ogologo cantilever.

Cantilever ogologo na-mkpa ka a gbanwee izute formwork elu nke imewe chọrọ. Dị ka ebe dị anya site na ọkọlọtọ ruo na nke kacha nso octagonlock diski bụ 250mm ma ọ bụ 325mm (isi olu akwa elu), na-atụle ịdị elu nke mgbanwe U isi, ya mere ogologo nke cantilever hà ma ọ bụ karịa 300mm n'ozuzu.

Ọnọdụ kachasị ike nke nkwụsi ike nke mkpọchi mkpọchi diski dị na nkwado nkwado, iji mụọ mmetụta nke cantilever ogologo a na ikike nkwụsi ike nke usoro ihe atụ, na-ewere 4 × 4 na-agbatị 1 nzọụkwụ na 4 × 4 span 4 nzọụkwụ formwork support Ọdịdị dị ka ihe nyocha (ọkọlọtọ nzọụkwụ h = 1500mm), tụlee iche iche ogologo nke cantilever ọgwụgwụ na- 300 ~ 1000mm, na-eme ka nonlinear kwụsie ike site 50mm oge ọ bụla maka ịgbakọ.

Na cantilever ogologo na-amụba na formwork support kama, kacha mwepụ na-aga, nkwado support Ọdịdị na-ekwe ekwe ekweghị ka obodo akwusighi na n'elu cantilever ọgwụgwụ. E gosiputara ọnọdụ enweghi nsogbu n'ime ọgụgụ ndị a:

Ngụkọta oge nke ike kwụsiri ike nke na-arụ ọrụ nke 4 × 4 na-agbatị 1 nzọụkwụ na 4 × 4 na-adịru 4 usoro diski mkpọchi usoro nkwado na ogologo nke akụkụ cantilever na-egosi na tebụl na-esonụ:

Site na tebụl a, ọ gosipụtara na ogologo cantilever nwere mmetụta dị ukwuu na ikike nkwụsi ike nke nkwado nkwado. Ọmụmaatụ: maka 4X4 gbatịa 4 nzọụkwụ nkwado Ọdịdị, mgbe a = 300mm, ya ike loading ikike Pcr = 77.91KN, ma ọ bụ mgbe a = 1000mm, ya anụ loading ike Pcr = 21.97kN, mgbe a = 300mm, kwekọrọ ekwekọ ikike ikike 27,9% .

Nsonaazụ gosiri na cantilever ogologo nwere mmetụta dị ukwuu na ikike nkwụsi ike nke usoro nkwado nkwado nke formwork. Yabụ, na imewe injinịa na iwu ụlọ, ogologo nke cantilever kwesịrị ka a chịkwaa ya iji hụ nchekwa nke ụdị nkwado ụdị akwụkwọ a. Ndị na-ese ihe kwesịrị ịdabere na ibu (vetikal, kwụ) nha. Maka ogologo cantilever ogologo, usoro a ga - eji belata usoro iji belata nchekwa nke usoro nkwado ụdị.
