Introduction of routine practice of steel structure reinforcement works

Steel structure is favored by many customers in the market with its unique advantages and characteristics. Its more important advantage is that the construction speed is fast, which can adapt to many residential needs such as homestays. And people worry about the steel structure of the house is whether its structure is as stable as the normal house, in fact, we do not have to worry, although the steel structure of the house is built quickly, but it does not mean that it will have a loss in the degree of robustness.

1. Common steel structure reinforcement methods:

With load reinforcement, construction is very convenient, but also more economic. It IS USED WHEN THE STRESS OF THE COMPONENT (or connection) is less than 80% of the design strength of the steel, or the component is not very damaged (breakage, deformation, warping, etc.). At this time, in order to make the new reinforcement member participate in the force, sometimes it is necessary to take temporary unloading measures to the reinforced member. In addition, in the reinforcement should pay attention to not affect the normal use of other components.

Foundation reinforcement, proposed to remove from the original structure should be reinforced or updated components. When the structure is damaged seriously or the bearing capacity of the original section is too small, it must be used when the ground is strengthened or updated. Temporary support shall be provided so that the replaced member is completely unloaded; At the same time, the safety of the whole structure after the replacement structure is removed must be guaranteed. Increasing or strengthening the supporting system is also an effective method to strengthen the structural system.

2, steel structure reinforcement details

When enlarging section is used to reinforce steel members, the selected section form should be in favor of strengthening technical requirements and considering existing defects and damage. The reinforcement of steel structure engineering needs to start according to the actual addition, many times different parts of the quality requirements for reinforcement are different, so the steel structure engineering should choose the appropriate reinforcement method for different parts of the reinforcement.

3. Repair and reinforcement of cracks

Steel structure engineering structure due to repeated load and material selection, construction, manufacturing, construction and installation improper has the extensibility or brittle fracture inclination crack damage, should try to repair. Steel structure engineering due to the pressure of different loads, a lot of steel components are damaged to different degrees, so the steel structure engineering for the large damage of steel components can be replaced, and then in the reinforcement, improve the overall quality of steel structure engineering.
