Steel structure factory building reinforcement design how to
Release time:2020-07-19
At present, steel frame structure is widely used in engineering construction, industrial plants, highway bridges and other structures, especially steel structure workshop is the key in recent years. With the change of time, the steel structure workshop will appear a variety of hazards, so it is very important to show detailed and reliable structural reinforcement solutions.
In this way, how to strengthen and transform the steel structure workshop?
1、 Master the raw material characteristics and management system of steel structure workshop
In the whole process of strengthening the steel structure workshop, it is necessary to master the reliable level of the industrial plant engineering construction, including the characteristics of the steel frame structure raw materials, the structure management system and the existing structural problems and damages. The experts with working experience and technical ability of the organization carry out unified scientific research on this problem, and analyze the current situation and level of bearing capacity of steel structure workshop, so as to lay a foundation for the reliability design of structural reinforcement in the next step.
2、 Select economic development, effective and reliable structural reinforcement measures
The selection of the plan for the reinforcement and reconstruction of the steel structure workshop must consider the load status of the structure and the bearing capacity characteristics of the structure after reinforcement. From the perspective of ensuring the rationalization and credibility of the carding structure, the structural reinforcement measures that are effective in economic development and conducive to engineering construction are selected. For example, the connection technology of new and old structures or raw materials should be adopted, and the current construction level of structural reinforcement engineering should be integrated, and the comprehensive performance index should be considered as much as possible. In addition, measures must be taken to reduce the adverse effects on the surrounding environment and adjacent buildings and reduce the construction cycle time in the reliability design of the steel structure workshop structure reinforcement plan.
3、 The bearing capacity of the original structure shall be applied as much as possible
In order to prevent damage to the original structure, the bearing capacity of the original structure must be used as much as possible in the whole process of structural reinforcement. The reliability evaluation analysis and inspection of the load-bearing parts of the industrial plant are carried out, and the current bearing capacity is generally mastered. Then, according to the inspection report, a large number of original load-bearing components are saved and used. Due to the large-scale disassembly and assembly of steel structure workshop, it is very easy to cause relatively serious damage to the components, and the connection difficulty coefficient of new and old structures is very large, which will lead to a certain level of damage to the actual effect of structural reinforcement, and then to the application of steel structure workshop in the middle and later stage has great safety risk.
4、 Quality management in the whole construction process of structural reinforcement engineering
In the whole construction process of steel structure plant structure reinforcement project, it is necessary to enhance the inspection of specific structure, accurately grasp the specific situation and damage situation of the current structure, and immediately reduce the safety risk. The technical measures of structural reinforcement quality management include the fabrication of steel frame structure, welding, installation, screw connection, spraying of anti-corrosion and fireproof materials and installation of profiled plate. In the whole process of structural reinforcement of steel frame structure, it is necessary to carry out product quality inspection on the applied parts and components. If any problem is found to be inconsistent with the inspection results or not found during the inspection, immediate preventive measures should be taken to ensure the reliability and effectiveness of the structural reinforcement plan to a great extent.
