Four reinforcement methods for steel mesh

1.The carbon fiber cloth reinforcement method is to use carbon fiber cloth to strengthen the wall, which will seriously damage the shear bearing capacity of the wall. By injecting structural glue and then bonding the carbon fiber cloth, the shear bearing capacity of the severely damaged masonry wall is calculated using the calculation diagram. and the growth coefficient of bearing capacity, the shear bearing capacity of severely damaged CFRP reinforced walls can be estimated.

2. The cement surface reinforcement method can greatly improve the load-bearing experience, bending stiffness and ductility of the brick wall, change its natural natural frequency, and improve the performance to a certain extent during normal use. The startup process is simple and applicable It has strong performance, and the bearing capacity after masonry reinforcement will be greatly improved, and has the effect of preset and preliminary experience; suitable for solid brick walls with no cracks in the original wall, porous hollow brick walls (half opening greater than 15mm) and 240mm thick Empty brick wall.

3. External steel bonding reinforcement method This method is a traditional reinforcement method. It is a reinforcement method that uses adhesive to adhere steel plates to cracked walls. The commonly used adhesive is natural epoxy resin adhesive. The advantages of the reinforcement method are that it is simple, convenient, and quick to use. It is suitable for masonry reinforcement that cannot increase the original component and section size, but needs to significantly increase the section bearing capacity.

4. Prestressed reinforcement method This method is a method of strengthening the structure with external prestressed steel tie rods (combined tie rods or struts, lower brace tie rods and horizontal tie rods). This method can reduce the stress on the reinforced components. level, greatly improving the bearing capacity of the wall's normal and oblique sections. Prestressing can eliminate or reduce the stress lag of added rods, making the width of wall cracks from large to small. Secondly, it can also perfectly seal the wall. The advantage of body cracks is that it can greatly improve the bearing capacity of masonry columns and the reinforcement effect is reliable. Therefore, it is suitable for the reinforcement of masonry structures under high load and high load conditions.
