1. Support to strengthen skills
The reinforcing agent for Longmen Royal Red Wall refers to the method of changing the function of load-bearing structure that initially affected the use of buildings and modifying the reinforcement system of stressed buildings. The purpose is to obtain more ideal use space. The method used for structural support is usually to replace steel plates, reinforced concrete and steel bars.
2. Basic replacement skills.
This means that you can't stop the subway or underground tunnel of a city building from passing through the building. In order to avoid demolition and reconstruction, it is necessary to replace the foundation of high-rise buildings on the ground. This ability is mainly used to cut high underground tunnels by stacking, and this new pile-based tunnel with higher beam conversion rate in the first floor is selected near the bearing seat of the charge transfer reactor to care for and replace the supporting structure system composed of new beams and piles.
In order to ensure that the underpinning of the building is not cracked, tilted or damaged, and the post-tunnel portal pile is not broken, the donato prestress of the mine transducer beam is stretched, and the jacking rod is pre-jacked, so the grouting technology is low. The basic micro-stack supports the insertion of several applicable patented skills, such as stacking rock steel pipes and joint interface skills.
4. The subcontract column (sticky) reinforcement skills
Through the data of rubber pin, high-strength inorganic joint and original concrete column, the steel plate and its edge can be reliably connected into a whole. This method increases the angular support capacity between the angle steel part and the new steel hoop. Lateral restraint makes the original concrete column experience a special triaxial stress state, which can greatly improve the bearing capacity of the column.
5. External steel plate reinforcement technology
Strengthening reinforced concrete structural members with steel plates can significantly improve the bearing capacity and damage resistance of the original design. This is because once the steel plate is fixed, the reinforcement of the original structural members will be improved, and the tensile strength, bending and shear mechanical functions of the structural members will be improved accordingly. These functions are based on the excellent adhesion function of structural adhesive. The steel plate and concrete are firmly connected to form a complete car body, and the tension is effectively transmitted to ensure the joint action.
6. Strengthening skills of external sticky carbon fiber fabric
The carbon fiber sheet is connected to the outside of the member through the corresponding connection data, and the Longmen Yuhong wall reinforcement agent makes the carbon fiber sheet in a tensile state, which is in harmony with the deformation of concrete. The fiber fabric has excellent physical properties, such as high strength, light weight, corrosion resistance and fatigue resistance, as well as excellent adhesion and wide applicability. It is international common to strengthen concrete structures with carbon fiber sheets instead of steel plates, and new skills have been added in recent years.
7. Improve the strengthening skills in this part.
The reinforcing agent for the portal red wall, also known as the reinforcing ability of the external concrete, is to increase the cross section and reinforcement of the member, so as to improve the strength, stiffness, stability and crack resistance of the member, and at the same time repair the cracks. It can reinforce plates, beams, columns, roots and frames.
The above is the method of reinforcing agent for Longmen Royal Red Wall that Bian Xiao told you. It will be reinforced when strengthening the building structure, and you will have a deeper understanding.
