What are the specific requirements for the load-bearing capacity and levelness of the installation floor of the fixed plate?

The load-bearing capacity of the fixed installation ground is the primary safety foundation.The ground must be able to withstand the total weight of the fixed plate,maximum working load(including workpieces and fixtures),dynamic impact,and at least 1.5 times the safety factor.For large platforms,professional accounting is required to ensure that the foundation is made of reinforced concrete poured as a whole,with sufficient thickness and reinforcement.It is strictly prohibited to install it on raised floors or soft ground.

The initial level of the ground is the guarantee for efficient leveling.In the coverage area of the fixed plate support point,the preliminary levelness error of the ground should be less than 3mm/total length,and the flatness should ensure that the support pad iron or anchor bolt can make stable contact without suspension.Usually,it is required that the ground be polished or self leveling to ensure the stability of large-area contact.

In addition,the ground should have high compressive strength(usually not lower than C25 concrete grade)and good seismic resistance,and be connected to the main foundation of the workshop to avoid independent settlement.The environment should be dry and moisture-proof to prevent foundation deformation or corrosion of supporting structures.Before installation,it is necessary for the structural engineer to conduct final confirmation and acceptance based on the platform technical parameters and workshop geological report.
