When reinforcing the construction of buildings, different methods are required due to varying factors such as the structure, usage, and environment. How many of the 8 commonly used methods for reinforcing building structures do you know?
1. Deep crack grouting reinforcement technique
2. The internal deep cracks in the structure are treated with grouting reinforcement and water leakage prevention, restoring the integrity of the structure. This is a mature skill repeatedly applied to large concrete structures such as embankment dams and high-rise building slabs.
3. Currently, grouting treatment has been applied to medium-deep cracks up to 2 meters, and random core samples inspected indicate that the density and strength of the concrete structure meet the requirements after grouting. For the adjustment of building structure and foundation reinforcement techniques, which address partial or overall misalignment in building and engineering structures due to various factors (such as foundation settlement and foundation construction), methods like stress relief, pile cutting, and jacking are employed. Construction is carried out using the information feedback method to correct the misalignment.
2. Tote strengthening skills
Refers to the functional transformation through the modification of the existing load-bearing structure, employing methods such as strengthening the building's housing system to achieve greater ideal usable space. The commonly used methods for structural replacement typically include steel beam replacement, reinforced concrete replacement, truss replacement, etc.
3. Foundation Underpinning Techniques
This refers to the situation where subway tunnels or underground passages in urban construction cannot be prevented from passing underneath buildings. To prevent the need for demolition and reconstruction, it is necessary to replace the pile foundations of high-rise buildings on the ground. This technique primarily involves the high-rise building's pile foundations that need to be cut through by the underground passages. First, a beam-type transformation layer is selected near the foundation to transfer the upper loads received by this part of the pile foundation to the new pile foundations on the outside of the tunnel. A replacement structure system composed of the replacement beam and the newly added piles is then used to replace it.
To ensure that the high-rise buildings under replacement do not suffer from cracks or tilting damage during the removal of the broken piles and tunnels, techniques such as pre-tensioning of replacement beams, pre-loading with jacks, and grouting at the pile bottom are employed. The pile foundation replacement can utilize various patented technologies, including micro-embedded rock steel pipe grouting piles and concrete interface bonding techniques.
4. Column Sheathing (Bonded) Reinforcement Technique This technique involves securely bonding angle steel and steel plate hoops to the original concrete column using adhesive bolts and high-strength inorganic bonding materials. This method, in addition to increasing the column's load-bearing capacity by adding the angle steel section, also enhances the original concrete column by the lateral restraint effect of the added steel plate hoops.
Three-axis stress condition, thus significantly enhancing the column's load-bearing capacity.
5. Girted Steel Plate Reinforcement Technique
The application of bonded steel plate reinforcement and strengthening in reinforced concrete structural components significantly enhances their original design load-bearing capacity and resistance to damage. This is due to the increased amount of reinforcement in the original structural components after the steel plates are applied, which in turn improves their tensile, bending, and shear mechanical properties. These properties are ensured by the adhesive bonding function of the structural adhesive, which firmly bonds the steel plate to the concrete, forming an integrated structure and effectively transferring stress for joint operation.
6. Carbon Fiber Reinforcement with External Adhesive Technique
7. By applying carbon fiber sheet materials to the surface of the components with bonding materials, the sheets can withstand tension and harmonize with the deformation of the concrete, sharing the load together. The fiber cloth boasts excellent physical properties such as high strength, light weight, corrosion resistance, and fatigue resistance, along with good adhesion and wide applicability. Replacing steel plates with carbon fiber cloth for reinforcing concrete structures has emerged as a new technique that has gained popularity internationally in recent years.
8. Increase cross-sectional reinforcement techniques
9. Also known as outsourced concrete reinforcement techniques, this involves increasing the cross-section and reinforcement of components to enhance their strength, stiffness, stability, and crack resistance. It can also be used for repairing cracks and similar issues. This reinforcement technique is widely applicable and can reinforce slabs, beams, columns, foundations, and roof frames, among others.
Based on different reinforcement objectives and requirements, this technique can be divided into reinforcement primarily for increased cross-section, reinforcement primarily for additional rebars, or a combination of both. Reinforcement primarily for increased cross-section requires appropriately equipped structural rebars to ensure the normal operation of the added concrete. Reinforcement primarily for additional rebars necessitates appropriately increasing the cross-sectional dimensions according to the rebars' spacing and protective layer requirements. In the reinforcement process, the rebars should be welded to ensure good bonding between the new and old concrete.
8. Reinforcement Skills
9. "Rebar Bonding" technique, also known as "Rebar Rooting" skill, involves drilling holes into the existing concrete structure, injecting structural adhesive, and rotating the new rebar into the holes. This technique is widely used for design modifications, adding beams, columns, cantilever beams, and slabs for reinforcement and alterations.
This skill is proposed to prevent structural damage during the drilling of holes in reinforced concrete structures, where conventional destructive methods such as hammering are used, along with reinforcement techniques around the hole openings. The technology for creating holes has been widely applied in high-rise building floor slabs, shear walls, and central cores.
