Building Reinforcements TRIZ Cases

A two-material earthing contact cuts concrete space and material use while improving corrosion resistance and grounding durability.

Thermally activated shape memory joining replaces threading or pressing to secure reinforcement with high clamping force and less effort.

Cold-drawn SMA wires are bundled and corrugated to avoid large field tensioning equipment while improving concrete adhesion.

Hydraulic or screw-driven cap and seal assembly improves post-tension anchor seating and reduces hazardous, unreliable seal attachment.

Explosion bonding collapses a CRA cylinder onto a steel core to eliminate gaps, improve bond consistency, and produce uniform corrosion-resistant clad billets.

A wave-shaped rebar and elongated mold form continuous stirrups with fixed spacing, cutting installation labor and time in rebar cages.

Spin or ultrasonic welding joins the anchor cover and tube to create a fluid-tight tendon seal with faster molding and better corrosion resistance.

A high-resistivity coating on tendon contact surfaces limits current flow and corrosion, extending prestressed concrete anchorage life.

Low-pH MgO or olivine cement enables direct carbon and glass fiber reinforcement while preserving bond strength, durability, and lower steel use.

Longitudinal cutouts expose the rod for welding while enclosed sections guide positioning, improving anchor integrity and shear resistance.

A two-part clamping separator stabilizes steel mesh during concreting while avoiding polystyrene panel damage in sandwich panels.

A wider thread profile covering over 30% of the bar shortens concrete fittings while maintaining load-bearing capacity.

Prefabricated steel mesh panels with interlocking splice bars cut on-site framework assembly time and reduce trip hazards during concrete reinforcement.

Mismatched thread pitches and phases induce galling in a threaded rebar coupler, preventing loosening without grout or screw locks.

Unequal roving bundles wrap the transverse rod on both sides, enlarging contact zones to resist axial tension and brittle joint failure.

A seal-carrier fixed to the reinforcement cage embeds and protects the seal, enabling diaphragm wall panel joints without costly formwork.

Pivotable FRP rebar cage connectors enable folding for compact transport while maintaining intersection strength during unfolding and handling.

A fiber-bundle core with a thick thermoplastic coating improves alkali resistance, strength, and bendability while avoiding thermoset curing cost.

Integrated receptacles and spacers hold reinforcing bars and formwork in place while the hoop reinforcement provides concrete shear strength.

Surface-textured retired FRP boards improve concrete adhesion and force transfer, reducing delamination in durable reinforced elements.

Shear-elastic cross-connections let tubular lattice reinforcement deform under load, improving concrete bond, ductility, and failure warning.

A flange-and-boot coupler joins duct segments across adjacent concrete spans, blocking fluid and debris ingress while allowing structural movement.

A clip parallel to rebar and a crack-inducing bolster improve concrete interlock strength at temperature-driven induced cracks.

Angled transition surfaces and convex portions redirect tensile stress, reducing cracks during lifting while preserving pile uplift and bearing performance.

A curable epoxy resin and hardener fill a coupling device to join rebars with less equipment and stronger fastening.

A support-equipped coupling body and blocked calcium aluminate mortar join elongated elements while reducing threading, torque, and on-site equipment demands.

A guide orifice and edge-mounted securing structures keep reinforcing bars vertical over block openings for consistent placement.

Pozzolanic cement chemistry protects aluminium mesh from alkaline corrosion and hydrogen formation while reducing reinforcement weight.

A single reconfigurable mold produces rebar support chairs at multiple heights and sizes, reducing mold changes, capital cost, and downtime.

Frustoconical couplers enable independent concrete-section tensioning while reducing curing delays.

This case shows how concrete force transfer units with steel reinforcement preserve prestressing strength while reducing coating complexity.

A portable adjustable tool uses latching arms to position rebar for accurate single-worker cage assembly across multiple sizes.

Pre-assembled rebar cage modules use overlapping opening nets to ease main bar installation while preserving reinforcement structure.

A grout chamber and spring-biased stops contain bonding material, anchoring upset rebar heads against pullout during seismic forces.

Rigid coupler bodies, flexible boots, and end flanges connect duct segments while resisting fluid ingress across concrete elements.

A co-pultrusion process combines UHMWPE with carbon or glass fibers to improve FRP rebar ductility, strength, and corrosion resistance.

Apertured, high-R-value tie connectors transfer shear through insulating panels while supporting fluidic material bonding.

Frame sensing, staged staplers, and carriage advancement automate consistent wire-grid attachment across bedding foundation sizes.

This anode assembly uses higher-conductivity ion-conducting material to target corrosion protection at critical metal parts in concrete.

A crank-link driver and spring-fed magazine speed rebar clip installation while reducing reloads and avoiding electricity or compressed air.
