WEDGE SHOCK-WAVE GAS DYNAMIC INSTALLATION FOR CONCRETE MOULDING Russian patent published in 2001 - IPC

FIELD: manufacture of building materials, mainly, formation of the structure of concretes and mortars on mineral binding agents for the conditions of plant fabrication. SUBSTANCE: device has a body with walls and a cover, and a wedge member. Detonation chambers are installed in the side and/or bottom walls and above the wedge member. One of the walls is movable, with a fixed inclined wall of the mould body adjoining it. The detonation chamber above the wedge member has a longitudinal section equal to: S_c= (P_p/P_av)[S_c(tgϕ+f_f)], where P_p is amplitude of dynamic pressure acting on concrete mix, P_av is mean pressure in the detonation chamber after passage of the detonation wave, S_c is area of surface of contact of concrete mix with the movable side wall, ϕ is wedge member taper angle, f_f is sliding friction coefficient at movement of the wedge member. EFFECT: complex of impulse effects and static pressures at moulding of concrete and reinforced- concrete products and masses, mainly, of tough concrete mixes. 4 cl, 2 dwg
