Description
Technical Field
the invention relates to a composite steel plate and a manufacturing method thereof, in particular to a composite steel plate for steel beam bending resistance reinforcement and a manufacturing method thereof.
Background
The carbon fiber cloth, the plate and other fiber products have high strength, small density, thin thickness and excellent working performance, are widely used for reinforcing the shear resistance, bending resistance, earthquake resistance and other properties of a reinforced concrete structure at present, can limit the cracking of the concrete and improve the crack distribution form. The reinforcing agent is used for reinforcing a steel structure, can obviously improve the bearing capacity of the steel structure, and improves the fatigue performance of steel members.
At present, fiber products such as carbon fiber cloth and the like are bonded with a concrete structure or a steel structure through epoxy adhesives. The carbon fiber cloth is used for reinforcing a concrete structure relatively mature, and a special adhesive is used for bonding the carbon fiber cloth and the concrete structure together at present. However, the use of adhesives to bond carbon fiber cloth, plates and steel members has the following drawbacks: (1) the difference between the thermal expansion coefficient of steel and the thermal expansion coefficient of carbon fiber cloth is large, and residual thermal stress is inevitably existed after the reinforcement is completed, so that the reinforcement effect is unfavorable. (2) At present, no special binder exists for reinforcing the steel structure by the carbon fiber cloth, and the adoption of different binders is bound to cause differences in reinforcing performance and is not beneficial to design and calculation. (3) Different binders have different sensitivity degrees to environmental factors such as temperature, humidity and ultraviolet rays, and the bonding strength can be reduced under the influence of some factors, so that the durability of the carbon fiber cloth reinforced steel structure is influenced.
the patent application No. 200710201781.0 discloses a method of truss-reinforcing a steel beam. The steel truss is additionally arranged at the bottom of the existing steel beam, so that the stress system of the existing steel beam is changed, and the value of the section inertia moment I of the existing steel beam can be greatly improved, thereby achieving the purpose of reinforcement. But the height of the truss is higher, and the use space of the building is greatly reduced by using the truss for reinforcement. In addition, the truss is made of more members and heavier, so that the dead weight of the original structure is increased greatly.
application No. 2008203028511 discloses a reinforcing structure for a steel crane beam. The utility model discloses a crane beam is consolidated through connecting the bracing post between steel crane beam and factory building steel column. The reinforcing method has the advantages of simple structure, less material consumption and no influence on the construction of a factory building. However, the method cannot greatly improve the bearing capacity of the steel beam and cannot fundamentally solve the problem of the bearing capacity of the steel beam. In addition, the method does not improve the fatigue properties of the steel beam, nor does it contribute to the corrosion resistance of the steel beam.
