Summary of Ground Construction Methods for Grid Steel Structure Platforms

Grid steel structure platforms are widely used in industries, warehouses, and other fields, and the construction quality of their ground directly affects the stability, safety, and functionality of the platform. The following is a summary of the ground construction method for the grid steel structure platform from several key steps.
1、 Preliminary preparation and site investigation
Before construction, a detailed survey of the site is required to understand the geological conditions, including soil bearing capacity, groundwater level, and other information. Based on the survey results, design the construction drawings and clarify the structural form and bearing requirements of the ground. At the same time, prepare the materials and equipment required for construction, such as steel, concrete, construction machinery, etc., and ensure that the material quality meets the standards.
2、 Basic processing
Foundation compaction: For grid steel structure platforms with high load-bearing requirements, the foundation should be compacted first. By using mechanical compaction, dynamic compaction and other methods, the compactness and bearing capacity of the foundation can be improved, and the later ground settlement can be reduced.
Setting the foundation: Based on the design load and geological conditions of the platform, select the appropriate foundation form, commonly including independent foundation, strip foundation, and pile foundation. During foundation construction, it is necessary to ensure that the size and position of the foundation are accurate, the quality of concrete pouring meets the requirements, and the foundation can stably bear the upper structure.
3、 Steel structure frame construction
Component processing and installation: Process and manufacture steel structural components according to the design drawings to ensure the dimensional accuracy and quality of the components. When installing on site, first install the columns, ensure the verticality of the columns through measuring instruments, and then install the beams, supports, and other components in sequence to form a stable grid structure framework.
Connection and fixation: The connection between steel structural components is crucial and is usually achieved through welding, bolt connections, and other methods. Ensure the quality of the weld seam during welding and comply with relevant standards; The bolt connection should ensure that the tightening torque of the bolts meets the design requirements to prevent loosening.
4、 Ground laying
Concrete pouring: After the steel structure frame is constructed, concrete pouring is carried out. Determine the strength grade and thickness of concrete based on the platform's usage functions. During the pouring process, vibration equipment should be used to ensure the compactness of the concrete, and the surface should be smoothed and compacted to ensure the flatness of the ground.
Ground treatment: After the concrete pouring is completed and reaches a certain strength, ground treatment can be carried out as needed. If ground polishing is carried out to improve the smoothness of the ground; For places with special requirements, ground coating can also be carried out, such as applying epoxy floor paint, to enhance the wear resistance, corrosion resistance, and aesthetics of the ground.
5、 Quality inspection and acceptance
After the construction is completed, a comprehensive quality inspection and acceptance of the ground of the grid steel structure platform should be carried out. The inspection includes the bearing capacity of the foundation, the stability of the steel structure frame, the flatness and strength of the ground, etc. By measuring, testing and other means, ensure that all indicators meet the design and specification requirements, and only after passing the acceptance can they be put into use.
