Beijing professional bonded steel reinforcement-Beijing Shengshi Haojie Reinforcement Company-Steel Structure

Beijing Shengshi Haojie Engineering Reinforcement Company generally restores or improves the load-bearing capacity of existing structures by reinforcing components and improving structural performance to extend their service life to meet the requirements of modern transportation. The main technical approaches for its transformation include strengthening weak components, adding auxiliary components, changing the structural system, reducing dead loads, strengthening piers and foundations, etc.
The current structural reinforcement methods mainly include the following aspects: Structural reinforcement layer reinforcement method. All the original structural surface paving is chiseled away or roughened, and a reinforcing layer of a certain thickness is added to increase the effective height of the main beam and improve the lateral distribution of structural load, thereby improving the overall bearing capacity of the structure. , enlarging the cross-section and reinforcing the reinforcement method. By increasing the cross-sectional area or reinforcement ratio of components, the strength, stiffness, and stability of reinforced concrete beams can be improved. , External prestressed reinforcement method. The external tension prestressed beam reinforcement method is the reinforcement method with the most obvious reinforcement effect and the most complex construction technology. It effectively increases the bending stiffness of the reinforced main beam and greatly improves the load-bearing capacity of the main beam without increasing the bridge's own weight. At the same time, if the construction process is reasonably arranged, this method can minimize the impact on traffic on the bridge and even organize construction with limited open traffic. , Pasting steel plate reinforcement method. Use adhesives and anchor bolts to stick and anchor the steel plate to the tension surface or other weak parts of the concrete structure so that the steel plate and the reinforced concrete structure form an integral part to improve the load-bearing capacity of the structure. , Change the structural stress system reinforcement method. Changing the stress system of the bridge structure to improve the overall bearing capacity of the structure is a reinforcement method that changes from passive to active. , anchor shotcrete reinforcement method. The reinforcement method transformed from tunnel construction is mainly used to reinforce and repair concrete beams with insufficient shear strength due to small fulcrum cross-section sizes. , Add horizontal connection reinforcement method. A reinforcement method is achieved by adding lateral bridge connections to improve the lateral load distribution pattern of the superstructure, thereby improving the overall load-bearing capacity of the structure. Generally used in girder-shaped bridge projects with no or few internal beams and I-shaped cross-sections. Cast-in-place concrete beams or steel beams are often added between adjacent main beams to improve the lateral bending stiffness. , pasting carbon fiber cloth reinforcement method. Carbon fiber reinforced composite material is a concrete structural reinforcement material with excellent performance. It has the advantages of high strength, low density, corrosion resistance and fatigue resistance. The reinforcement method is to use resin materials to paste carbon fiber cloth or plates on the surface of concrete structures or components to form a composite body. Through the collaborative work of carbon fiber cloth and the structure, the purpose of reinforcing the structure and improving the stress performance is achieved.
