Introduction of Steel Sheet and EPOXY Composites
Features
The steel sheet is applied to the outside of the damaged structure by steel sheet, and the steel sheet is fixed with the chemical anchor to the structure, and then the EPOXY repair material is added to make the steel sheet and the structural body together. Strength and toughness (such as the column of the axial force, beam bending moment and shear) to resist external forces. Only in the coated steel sheet before the original structure of the flaws should be the first repair (such as cracks or steel exposed, etc.).
Reinforcement of H - beam and EPOXY Composite
Features
The new steel beam reinforcement method uses the H-beam as the reinforcement measures, the steel beam end to stiffen the full-page H-beam steel and chemical anchor bolt fixed in the structure, the steel beam top and RC into the special EPOXY Repair materials, so that steel beams and structural body into one, increase the strength and toughness of the structure to resist external forces. The newly added steel girders form the structure of the lattice beam to reduce the span of the floor to achieve the effect of stiffening, in order to enhance the capacity of the floor.
Example:
SP-869 steel plate reinforced filling material
Product description
SP-869 low-pressure irrigation material for the low viscosity, room temperature hardening of the epoxy resin plate reinforcement injection material, is currently widely used in concrete structure sets of steel plate after the reinforcement of the use, can be a strong package of the main body and the beam structure To prevent the earthquake caused by the beam beam shear damage.
Characteristics
(1) no shrinkage - no cracks after filling any cracks.
(2) strong adhesion - in the steel plate and the interval between the injection, the effective plate and the cylinder into a strong structure support.
(3) mining low pressure, rapid injection, can effectively inject the resin into the cracks and steel plate of every detail, complete the pillar to form a strong support.
(4) impermeable, good durability.
| Use methods and precautions | ||
| (1) | Concrete crack injection surface must first remove the cement hardening layer, floating slurry, grease and other pollutants. | |
| (2) | To anchor the steel plate in the reinforcement surface. | |
| (3) | First A and B dose ratio prepared. | |
| (5) | Take an empty bucket into the A agent, stir with an electric stirrer while pouring B agent, stirring about 2 to 3 minutes, stirring evenly, the high pressure perfusion machine into the steel plate and the interval can be. | |
| (6) | Perfusion way from bottom to top, step by step into the infiltration, until the top of the vent hole EPOXY can be out. | |
| (7) | For safety and health considerations, please wear rubber gloves construction. | |
| (8) | The speed of hardening is controlled by the atmospheric temperature, absolutely can not increase or reduce the amount of hardener to control the rate of hardening, change A agent and B mixture ratio will cause hardening, reduce the physical properties of the glue. | |
| (9) | If you accidentally touch the hands or skin during construction, please wipe with a toluene cloth and wash with soap and water. | |
