Abstract
A brick or masonry structure is drilled to receive an elongate reinforcing assembly comprising a core with one or more fabric sleeves over most of its length. The sleeves are injected with grout that seeps through the fabric to bond to the drilling wall. It may bond directly to the core or to a tube through which the core extends. The core is anchored to the structure at or near the mouth of the drilling while a tube farthest from the mouth may have a connection to the core that allows the core to be pulled towards the mouth with progressively greater resistance.
Claims24
A method of reinforcing a structure comprising:
- drilling into the structure,
- inserting into the drilling an elongated reinforcement core carrying over part of its length a permeable fabric sleeve, injecting cementitious grout into the sleeve to expand said sleeve against the wall of the drilling, some grout seeping through to bond to said wall and thereby locally securing said core, and
- providing and anchoring by anchoring the reinforcing core at a zone distinct and separate from the grouted sleeve to complete a reinforcing assembly.
