  • Patent number: 6481174
    Abstract: An auxiliary tool for filling of an organic and/or inorganic mortar mass in a bore (B) and cooperating with an injection tool (D) connectable with a delivery tube (E) or a delivery hose, with the auxiliary tool (1, 6, 12) including a filling member (2; 7; 13) having an axial through-bore (3; 9; 17) through which the mortar mass (M) is injected into the bore (B), and an outer diameter selected so that a back flow of the mortar mass (M) in a direction toward a bore mouth is prevented, and an element for pinning the filling member (2; 7; 13) on a free end of the delivery tube (E) or the delivery hose.

  • Patent number: 5115622
    Abstract: Metal reinforcing members (3) are attached by bonding to a surface in the tension zone (1a) of a concrete structure component (1) for reinforcing the component. To prevent the ends of the reinforcing members (3) from separating from the structural component (1) when the component is subjected to load, attachment elements (4) clamp the ends of the reinforcing members against the surface of the component in addition to the bonding action. The attachment elements (4) apply such high compressive forces to the structural component, so that potentially damaging tension and shear forces can not be effective.
