Abstract

The invention discloses a composite steel plate and a manufacturing method thereof. The composite steel plate comprises a sandwiched steel plate, fiber bars or bundles, anchors and backing plates, wherein the sandwiched steel plate comprises an upper panel and a lower panel, webs are arranged between the upper panel and the lower panel at equal intervals, the fiber bars or bundles penetrate through the sandwiched steel plate, and the two ends are fixed by the anchors and the backing plates. The composite steel plate is light in weight, thin, large in bearing force, high in anti-fatigue performance, easy to construct and capable of improving the working performance of reinforced steel beams. The fiber bars or bundles used in the composite steel plate are small in diameter, and the thickness of the composite steel plate can be greatly reduced. The hollow stainless steel plate and the fiber bars or bundles are high in corrosion resistance, and the composite material composed of the two materials has weldability and can be used for strengthening and reinforcing the steel beams.

Description

technical field

[0001] The invention relates to a composite steel plate and a manufacturing method thereof, in particular to a composite steel plate for bending resistance reinforcement of steel beams and a manufacturing method thereof. Background technique

[0002] Fiber products such as carbon fiber cloth and board have high strength, low density, thin thickness, and excellent work performance. At present, they are widely used in the reinforcement and reinforcement of reinforced concrete structures such as shear resistance, bending resistance, and earthquake resistance, and can limit concrete cracking. Improve the distribution of cracks. It can be used to strengthen the steel structure, which can significantly improve the bearing capacity of the steel structure and improve the fatigue performance of the steel components.

[0003] At present, fiber products such as carbon fiber cloth to strengthen concrete structures or steel structures are bonded to the structure through ...
