The thickness of the industrial workshop floor usually has a thickness of 10cm-20cm depending on the structure and load requirements that calculate to have the actual thickness. The process of pouring concrete on the factory floor consists of 7 steps which are strictly implemented and closed with glass.
Step 1: Treat the ground flat
Step 2: Spread base stones
Step 3: Flatten the base rock
Step 4: Lining waterproof nylon
Step 5: Construction of wire mesh
Step 6: Pour concrete floor
Step 7: Check required concrete curing.
Before carrying out the concrete pouring, it is necessary to prepare and pay attention to the problems of choosing materials. Because the material used determines the quality of the concrete floor, which is clean and meets the function at the center
+ Sand should choose cutting with large modulus from 2-3,3
+ Aggregate stone or gravel: The grade is at least 1.5 times higher than that of the concrete intended to be manufactured. The size of the largest stone sphair is less than 1.3 the minimum thickness of the concrete member.
Mix vertical concrete mortar with the proportion of concrete grade. Make sure the mortar components are really homogeneous. Mixing concrete by machine to increase the efficiency and quality of concrete reducing the amount of cement used as well as labor
The height of free fall of concrete is not more than 1.5 - 2m to avoid stratification of concrete
+ For residential houses, the floor does not need reinforcement of the frame and belt when pouring the floor, because the floor has a wide width and a small thickness of 8-10cm. However, with the factory, it is necessary to construct an additional layer of steel mesh because of the higher load-bearing requirements.
+ Ensure the requirements for waterproofing the floor of the workshop, avoiding the situation of floor moisture causing damage in production and storage of materials, products or machines. Especially for production factories, food warehouses, products are susceptible to mold, lack of hygiene and safety.
+ Pour concrete on the factory floor in the reverse direction. The floor is divided into strips for pouring concrete, each strip is 1-2m wide. Proceed to pour each strip, in order from inside to outside, from low to high.
+ It is necessary to ensure that the process is carried out continuously, to avoid creating stops, unless the workshop is too large, it is necessary to have an effective stopping circuit treatment solution.
+ When pouring concrete on the floor of the workshop, large projects should pay attention to the weather, avoid the time when the soil is wet, there is rain, which disrupts the concrete pouring, directly affecting the quality of the work. In case you need to build a workshop in the rainy season, the solution to build a pre-engineered steel factory is usually to assemble the frame and roof before pouring concrete on the floor.
+ When pouring the floor of the workshop to about 1m from the main beam, start pouring the main beam. Pour concrete beams to about 5-10cm from the top of the floor formwork and continue to pour concrete floors.
+ Avoid standing water at the ends and corners of the formwork, along the wall of the formwork compartment. All operations such as compacting, squeezing, and rubbing must be carried out immediately, in the form of rolling each area that has been poured for 15 minutes.
