What are the reinforcement methods for building structures

Building structure reinforcement refers to strengthening the stability of the building structure. There are many reinforcement methods, and below are some reinforcement methods listed by the house tilt correction company. Let's take a look together.

1. Anchor bolt anchoring method This method is applicable to the renovation and reinforcement of concrete load-bearing structures with concrete strength grades of C20~C60; Not applicable to the above-mentioned structures and lightweight structures that have been severely weathered.

2. The advantages and disadvantages of the wire winding method are similar to those of the enlarged section method; Suitable for reinforcement of concrete structural components with insufficient diagonal section bearing capacity, or for situations where lateral restraint is required on compression members.

3. The advantages of the replacement concrete reinforcement method are similar to those of the enlarged section method, and the reinforcement does not affect the clearance of the building, but it also has the disadvantage of long wet operation time during construction; Suitable for reinforcing concrete load-bearing components such as beams and columns with low concrete strength or serious defects in the compression zone.

4. In addition to the similar advantages of pasting steel plates, the method of pasting fiber-reinforced plastic reinforcement also has the advantages of corrosion resistance, moisture resistance, almost no increase in structural weight, durability, and low maintenance costs. However, it requires specialized fire protection treatment and is suitable for concrete structural components and general structures with various stress properties.

5. The method of increasing cross-section reinforcement has a simple construction process, strong adaptability, and mature design and construction experience; Suitable for reinforcing concrete in beams, slabs, columns, walls, and general structures; But the wet operation time of on-site construction is long, which has a certain impact on production and life, and the net clearance of the reinforced building is reduced to a certain extent.

6. The bonded external steel reinforcement method, also known as wet external steel reinforcement method, has reliable stress, simple construction, and small on-site workload. However, it requires a large amount of steel and is not suitable for use in high temperature places above 600C without protection; Suitable for reinforcing concrete structures that do not allow a significant increase in the cross-sectional size of the original components, but require a significant improvement in their load-bearing capacity.

7. The method of reinforcing by pasting steel plates is fast in construction, with no wet operations on site or only a small amount of wet operations such as plastering. It has little impact on production and life, and after reinforcement, it has no significant impact on the appearance and original clearance of the original structure. However, the reinforcement effect largely depends on the bonding process and operation level; Suitable for reinforcing bending or tensile components that are subjected to static forces and are in a normal humidity environment.
