In the process of reinforcement design and construction of steel structure buildings, the staff should combine the actual situation to make a more ideal design content. It should be carried out without affecting the working life, retain the original structural components as far as possible, reduce the demolition workload, and the retained part should have sufficient safety and durability, and have the use value. The reinforcement design should consider the impact of the construction site, each pipeline, adjacent buildings and adjacent roads, and consider the feasibility and convenience of construction. The following reinforcement home will bring you the construction points of steel structure building renovation and reinforcement.

(1) The design of steel structures and the strengthening of building structures should be undertaken by professionals.

Whether the building structure needs steel structure reinforcement should be assessed according to the reliability of the structure, and experts should give expert opinions in accordance with the relevant codes and specifications. The evaluation opinions can be used as one of the bases for structural maintenance and reinforcement design. Since the uncertainties facing the structural reinforcement design of the building are far more complex than the new project, the requirements of the owner should be considered, and the personnel responsible for the maintenance and reinforcement design should not only have a strong structural theory and a clear structural concept, but also have rich engineering experience, so as to comprehensively and systematically analyze the problem and propose a more reasonable structural reinforcement design scheme.

2. In the renovation and reinforcement design of steel structure, the relationship between component and structure, part and whole, temporary and should be handled well.

When some components do not meet the requirements, they must be reinforced, but the reinforcement of the structural system is often ignored, and the steel bar designer should consider the safety of the entire structural system. When the reinforcement of individual components does not affect the mechanical properties of the whole structural system, local reinforcement can be carried out. When the whole structure does not meet the requirements, the whole structure should be strengthened. Temporary steel structure reinforcement requirements can be appropriately reduced.

3. The reinforcement of steel structures must be in a scientific order. Hainan steel wholesale

Usually, the structural damage caused by high temperature, high humidity, freeze-thaw, cold brittleness, corrosion, vibration, temperature stress, shrinkage stress, uneven settlement of the foundation should be dealt with first, and effective measures should be taken in the reinforcement to eliminate or limit its harmful effects from the source, and correctly determine the reinforcement treatment time to avoid new damage to the reinforced structure.

Under normal circumstances, the reinforcement of the building structure should be unloaded or partially unloaded, and the reinforcement should be carried out in a certain order after unloading. Generally speaking, first reinforcement and then demolition; First reinforce and then open the hole; First the foundation, then the column, beam, plate; First the important components, then the secondary components, and finally the protection and protection work.

In general, after the local or local reinforcement of the structure, it does not mean that the overall bearing capacity of the structure will be improved or safe, and its safety also depends on whether the initial structural plan and layout are reasonable, whether the connection between the components is reliable, whether the original structural measures are appropriate and effective, and so on. These are all connotations of structural integrity or overall robustness of the structure. When designing concrete structures for reinforcement, structural engineers should check and evaluate the integrity of the structure to study whether the corresponding reinforcement is needed, rather than just focusing on parts or parts of the structure.
