Building Repairs TRIZ Cases

A single device combines pull and wedge bars with a slide hammer to remove glued elements without damaging surfaces.

Inclined joints in the internal lining eliminate horizontal adhesive seams, raising critical re-entrainment velocity to prevent acid-mist fallout.

A sheathing retaining anchor uses a compression mechanism to drive wedges into an interference fit within the bore.

Internal prismatic plate attachment reinforces concrete nodes against seismic stresses without invasive external scaffolding.

Jack assemblies lift concrete slabs via side contact, eliminating unsightly drill holes and mud cleanup.

Standoff retainers space cladding panels from degraded concrete, creating formwork for curable material injection that restores structural strength.

Ductile textile-adhesive composites enhance masonry resistance to horizontal loads by enabling plastic deformation and energy dissipation during seismic events.

Flexible laminate sheets wrap around cores to form adjustable concrete columns, replacing bulky Sonotubes that require large storage spaces.

A lifting tower system uses bidirectional rotational power and threaded rods to raise structures in a single continuous stroke.

Inverting wedge orientation prevents tension loss while a composite clamping element ensures uniform pressure distribution.

Segmented tensioning devices maintain laminate prestress during adhesive curing, eliminating the need for continuous mechanical clamping.

Elevating flooring ends creates ventilating spaces for airflow drying without removing the original floor structure.

A polymeric sealing element compresses into narrow gaps and expands to grip pavement walls securely.

A window buck with a right trapezoid cross-section and beveled edges secures directly to drywall panels without intermediary metal angles.
