How to strengthen the metal shop buildings to ensure its firmness and safety?
Steel structure is a structure composed of steel, which is one of the main types of building structures. At present, steel structures are widely used in buildings, workshops, bridges and other structures, and workshops are one of the steel structure buildings. The metal shop buildings mainly refers to the main load-bearing components composed of steel. The use of metal shop buildings will cause various damages over time. At this time, the steel structure factory building will need to do a good job of reinforcement treatment and targeted reinforcement design to provide a complete and reliable reinforcement solution for the reinforcement of the steel structure factory building.
1. Fully understand the material properties and systems of metal shop buildings. In the reinforcement process of the steel structure factory building, it is first necessary to understand the reliability of the factory building, including the performance of the steel structure material, the structural system, the existing structural problems and damage. Organize experienced and skilled professionals to conduct unified research on these issues, analyze the stress state and bearing level of metal shop buildings, and lay a foundation for the next step of reinforcement optimization design.
2. Choose economical, reasonable and reliable reinforcement measures. The selection of the reinforcement design scheme for a steel structure factory building needs to fully consider the load-bearing state of the structure and the stress characteristics after reinforcement. From the perspective of ensuring the rationality and reliability of the veneer structure, economical and reasonable reinforcement measures that are convenient for construction are selected. If the connection technology of new and old structures or materials is adopted, combined with the existing steel bar construction level, comprehensive technical indicators shall be considered as much as possible. In addition, in the optimization design of the metal shop buildings reinforcement scheme, effective measures need to be taken to reduce the negative impact on the surrounding environment and adjacent buildings and shorten the construction period.
3. Try to use the bearing capacity of the original structure. In order to avoid damage to the original structure, the bearing capacity of the original structure should be utilized as much as possible during the reinforcement process. Carry out reliability identification, analysis and testing on the load-bearing structural components of the factory to understand its existing load-bearing capacity as a whole, and then retain and use more original load-bearing components according to the test report. Due to the large-scale dismantling of the metal shop buildings, it is easy to cause serious damage to the components, and the connection between the old and new structures is difficult, which will have a certain impact on the reinforcement effect, thus burying a huge safety hazard for the later use of the steel structure factory building.
4. Steel bar construction quality control In the process of steel bar construction in metal shop buildings, it is necessary to strengthen the inspection of the actual structure, accurately grasp the actual situation and damage state of the existing structure, and reduce potential safety hazards in real time. The technical measures for the quality control of steel bars include the fabrication of steel structures, welding, installation, bolt connections, coating of anti-corrosion and fire-resistant coatings, and installation of profiled steel plates. During the steel structure strengthening process, the quality of the structural parts used should be checked. If the problem is found to be inconsistent with the test results or no problem is found during the test, remedial measures should be taken in time to ensure the reliability and effectiveness of the reinforcement scheme to a large extent.
