Practical methods for strengthening steel structure workshop

In recent years, steel structure welding processing is widely used in buildings, factories, Bridges, elevator Wells and other structures, especially steel structure factory is the focus of recent years. With the passage of time, a variety of problems are also around the steel structure of the plant, so it is necessary to find a complete and reliable reinforcement solution.

First, the overall understanding of the material properties and system of the steel structure workshop

In the process of strengthening the steel structure workshop, first of all, we need to understand the reliability of the workshop building, including the performance of the steel structure material, the structural system and the existing structural problems and damage. Organize the technical, experienced professionals to study these problems one by one, analyze the steel structure plant force status and holding level, for the next reinforcement optimization design to lay a foundation.

Choose an economic, reasonable and reliable reinforcement measure

The reinforcement design of steel structure workshop needs to consider the load-bearing status of the structure and the stress characteristics after reinforcement. In order to ensure the rationality and reliability of the finishing structure, economic and reasonable reinforcement measures are selected. For instance, adopt the connection technology of old and new structure or material, combine existing reinforcing construction level, consider comprehensive technical index as far as possible. In addition, effective measures should 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.

Three, 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 were evaluated, analyzed and tested for reliability, and the existing load-bearing capacity was understood as a whole. Then, more original load-bearing parts were retained and used according to the test report. Because of the large-scale disassembly of the steel structure workshop, it is easy to bring serious damage to the parts, and the difficulty of connecting the old and new structures is greater, which will have a certain degree of influence on the reinforcement effect, so as to bury a huge potential safety hazard for the use of the steel structure workshop in the later period.

Quality control in the process of reinforcement construction

During 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 potential safety hazards in real time. The technical measures for strengthening quality control include steel structure fabrication, welding, installation, bolt connection, coating of anticorrosive and fireproof coating and installation of profiled steel plate. In the process of steel structure reinforcement, quality inspection should be carried out on the used structural parts, and timely remedial measures should be taken to ensure the reliability and effectiveness of the reinforcement scheme to a large extent if the problems are found to be inconsistent with the test results or not found during the test.
