Reinforcement design of steel structure workshop

1. Comprehensive understanding of material properties and system of steel structure workshop

In the process of strengthening steel structure workshop, we must first understand the reliability of building structure, including the performance of steel structure material, structural system and existing structural problems and damage. Organize experienced technicians to conduct a unified study on these problems, analyze the current situation and strength of steel structure workshop, and lay a foundation for the next reinforcement and optimization design.

2. Choose economic, reasonable and reliable reinforcement measures

The selection of reinforcement design scheme in steel structure engineering needs to take into full consideration the stress status of the structure and the stress characteristics after reinforcement. In order to ensure the rationality and reliability of the veneer structure, economic, reasonable and convenient construction reinforcement measures are selected. Such as the use of old and new structure or material connection technology, combined with the existing level of reinforcement construction, as far as possible to consider the comprehensive technical indicators. In addition, effective measures must be taken to reduce the negative impact on the surrounding environment and adjacent buildings and shorten the construction period in the optimization design of the reinforcement scheme of steel structure workshop.

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 used as much as possible in the process of reinforcement. The load-bearing structural parts of the plant itself are analyzed and tested for reliability identification to fully understand their existing load-bearing capacity, and then according to the test report, more original load-bearing components are retained and used. Because the large-scale demolition of steel structure workshop is easy to cause serious damage to the components, and the difficulty of connecting the old and new structures will affect the reinforcement effect to a certain extent, thus to the use of steel structure workshop in the future buried huge hidden danger of safety.

4. Quality control in reinforcement construction

In the reinforcement construction of steel structure workshop, it is necessary to strengthen the detection of the actual structure, accurately grasp the actual situation and damage of the existing structure, and reduce the hidden danger of safety in real time. The technical measures for reinforcing bar quality control include steel structure fabrication, welding, installation, bolt connection, anticorrosion, fireproof coating and installation of profiled steel plate. In the process of steel structure reinforcement, the quality of the structural parts used should be checked, and the problems not found in the test or inconsistent with the test results should be found. Take remedial measures in time to ensure the reliability and effectiveness of the reinforcement scheme.
