AKKUM AKKUM & Associates, No. 1777, Rue 6.261, Auditorium Jean Paul II, Quartier Mbankolo B.P. 4966, YAOUNDE (CM). (57) A linerbolt removal tool, including: a housing; a moil supported for reciprocating movement by the housing; an inertial body located within the housing; a gas charged accumulator extending from the inertial body away from the moil; a piston moveable within the inertial body between a striking position at which the piston strikes the moil and a retracted position, whereby firing the piston from its retracted position to its striking position includes causing pressurised gas within the accumulator to accelerate the piston toward the moil, wherein the piston has a striking end for striking the moil and an opposing rear end; and a piston cap that encloses the rear end of the piston, wherein during firing, the piston and the piston cap initially accelerate together and prior to the piston reaching its striking position the piston cap separates from the piston, whereby the piston cap isolates the piston from the accumulator. ________________________________________ (11) 21411 Consulter le mémoire (51) B28B 1/00 (2018.01); E04B 2/00 (2018.01) ; E04C 1/00 (2018.01) (21) 1202300396 (22) 11/08/2023 (54) Nouveau procédé technico-écologique de construction de bâtiment à base de Bloc de ciment et ou en latérite traité.
