When reinforcing the structure of a building, different reinforcement methods need to be used due to different structural problems, different uses, and different environments. Let’s learn with the editor how to use wall plastering reinforcement.
1. Strengthen deep crack reinforcement skills
The internal deep cracks that appear in the wall plaster-reinforced structure are grouted and reinforced to prevent water filter leakage. Indispensable for repairing structures, it is also a complex skill applied to large concrete structures such as ponds, dams and high-rise buildings.
At present, the deepest crack in the grouting process is 2?m, and random sampling of drill cores shows that the density and strength of the concrete structure after grouting meet the requirements. Skills in correcting the structure of buildings and strengthening foundations and foundations. Partial or complete deviations caused by various factors (such as foundation settlement and foundation construction), such as stress relief methods, cutting methods, lifting methods, etc. Use feedback methods to implement corrections.
2. Support strengthening skills
It refers to the functional conversion of load-bearing structures that initially affect the use of buildings and methods of modifying the reinforcement systems of stressed buildings. The purpose of wall plaster reinforcement is to obtain a larger ideal space for its use. The methods used for structural support are usually replacement of steel plates, replacement of reinforced concrete and replacement of steel bars.
3. Basic Alternate Skill Base
This means you cannot stop city building subways or underground tunnels from passing through buildings. Wall plaster reinforcement In order to avoid demolition and reconstruction, it is necessary to replace the foundations of high-rise buildings on the ground. This capability is primarily used to cut highly underground tunnels through stacks, with the first layer beam conversion rate selected near the receiving chock of the charge transfer stack over this new pile foundation tunnel outside, for care replacement by new beams and piles A supporting structure system.
Wall plastering reinforcement To ensure that the building underpins cracking, tilting without damage and post-tunnel door pile crushing, mining transducer beam Donato prestressed tension, ejector pre-top, cement For low slurry skills, the base micro-stack supports inserting several patented skills applicable to it, such as stacked rock steel pipes and joint interface skills.
4. Subcontracted column (sticky) steel bar skills
Be able to reliably connect steel plates and steel plate edges into a whole through rubber pins and high-strength inorganic joint data and original concrete columns. This method of wall plaster reinforcement increases the angle support capacity of the angle steel section and the new steel plate hoop. The effect of lateral restraint causes the original concrete column to experience special triaxial stress conditions, which can greatly improve the support capacity of the column.
5. Reinforcement technology of external steel plates
Reinforced concrete structural members reinforced with steel plates can significantly improve the load-bearing capacity and damage resistance of the original design. Wall plaster reinforcement This is because once the steel plate is fixed, the amount of reinforcement of the original structural member is improved, and the tensile strength, bending and shear mechanical functions of the structural member are improved accordingly. These functions of wall plaster reinforcement are based on the excellent bonding properties of structural adhesives. The steel plates and concrete are firmly connected together to form a complete body, with tension effectively transmitted and working together to ensure.
The above is what the editor tells you about the use of wall plastering reinforcements. It will also be used to strengthen the building structure, and I have a deeper understanding of it. .
