  • Antiseismic reinforcement method for an existing building with a concrete block system
    Patent number: 4452019
    Abstract: A method of achieving earthquake reinforcement in existing buildings by piling hourglass-shaped concrete blocks within a beam pillar frame structure of a wall. The blocks are piled by staggering by half one pitch of the layer of concrete blocks and by filling the whole area within the beam pillar frame. The blocks are provided with stud plates that are welded to supporting bands which are in turn connected to the frame.

  • Earthquake-resistant reinforcement structure for an existing building with compression braces or tension braces
    Patent number: 4441289
    Abstract: A method for providing earthquake reinforcement for existing buildings by applying pre-compressive or pre-tensile stresses. In a first embodiment, a compression brace is provided on the beam pillar structure of the building in a diagonal direction to the structure so as to apply a pre-compressive stress to the compression brace. In another embodiment, a tension brace is provided on the beam pillar structure of the building so as to apply a pre-tensile stress to the tension brace in order to reinforce the building against an earthquake.
