Building Repairs TRIZ Cases

A press-fit object in a side hole generates compressive stress at the crack tip, canceling tensile loads and preventing new crack formation from stop-holes.

Modular prefabricated sections ensure construction accuracy while an integrated sand catcher prevents material loss during use.

Pre-welded gusset plates on full-length beams eliminate field welding, reducing labor costs while enhancing torsion resistance against seismic loads.

An expandable anchor device inserts into wall cavities to create secure mounting points.

A concrete crack seal tester uses test holes to measure liquid flow rates before and after filling.

A slab lift bracket uses segmented protruding members to distribute load across multiple anchor points within a concrete structure.

Composite hold-downs and bars replace corroded rebar in stem walls, eliminating rust transmission while maintaining structural integrity.

A bar connecting apparatus uses a reciprocating hammer to propel clips from a barrel onto intersecting reinforcing bars.

Prefabricated foundation structure uses non-cementitious fill as ballast to stabilize the central shaft against tension loads.

Segmented prefabricated elevator shafts bridge stairwell gaps and reduce construction time while maintaining building statics.

Continuous 3D sensing monitors structural distortions during cement injection, preventing excessive ground deformation and preserving built structures.

Flat-packed basalt fiber units connect via flexible bands to form lightweight reinforcement cages.
