Mechanism analysis of CFRP in concrete structure reinforcement

Carbon fiber reinforced polymer(CFRP) technology is widely used. It is suitable for the reinforcement and repair of various structural types and various structural parts, such as beams, plates, columns, roof frames, bridge piers, bridges, cylinders and shells, which require that the strength grade of the concrete at the base level is not less than C15.

Beam, column, slab, wall strengthening

Beam, column, slab, wall strengthening by bonded carbon fiber fabric, increase the crack resistance or shear capacity of the structure, improve the strength, rigidity, crack resistance and elongation of the structure.

Comparative of applicability of bonding CFRP and steel plate

Bonded CFRP and steel bonded reinforcement are bonded to the structure surface by resin cementing material, and form a whole force system with the structure to enhance the flexural or shear ability of the reinforced structure

Reinforcement steel bar pull-out test

The tensile test of steel bar is the field test of the anchoring force. After 48-72 hours of rebar planting, the tension meter (Jack) can be used to carry out the drawing test of the reinforced bar.

Precautions for the repair of concrete cracks

Before cracks are repaired, we need to measure the cracks first and choose the appropriate method according to the width of the cracks. When the crack width is less than 0.2mm, the crack repair glue is closed. When the crack width is in the 0.2mm~1.5mm, the crack injection adhesive should be injected into the fracture cavity with a certain pressure to strengthen and close the fracture cavity.

Methods for insufficient load-bearing capacity of machine room

For buildings used for machine rooms or record room, there are special requirements for floor loadings, such as higher load design values than ordinary office buildings. Therefore, it is necessary for the ordinary housing to be transformed into a computer room or record room to use or extend the original machine room.

How to test the construction quality of steel plate bonded

The method of steel encased steel reinforcement is necessary for strengthening the concrete beam and column structure that needs to increase the bearing capacity and seismic capacity of the section greatly.

Reinforcement & retrofit of reinforced concrete components

Reinforced concrete members will exhibit certain deformation or damage after exceeding a certain number of years. Some buildings or structures are used beyond their own limit of use; some are due to poor quality of construction; in this situation, it is often difficult to demolish and rebuild due to the reasons for the quality or service life. To continue to use it, the construction needs to be reinforced, reinforced, reformed and repaired.
