Indoor Prefabricated Floor Slab Methods

There are mainly two methods for making indoor prefabricated floor slabs:

Method 1: Wooden Mold Making Method

First, make a hollow mold. Select wooden boards of appropriate specifications and nail them together to form a hollow mold according to the designed size and shape of the prefabricated floor slab. This mold serves as the prototype framework of the prefabricated floor slab, and its dimensional accuracy and shape standardization directly affect the quality of the final prefabricated floor slab.

Next, arrange the reinforcement bars. Place the reinforcement bars reasonably in the hollow part of the made mold according to the design requirements. The function of the reinforcement bars is to enhance the strength and load-bearing capacity of the prefabricated floor slab, enabling it to withstand various loads during the use of the building. The specifications, quantity, and arrangement method of the reinforcement bars need to strictly comply with relevant building codes and design requirements.

Then, pour the cement. Evenly pour the well-mixed cement into the hollow part of the mold. During the pouring process, ensure that the cement is filled densely to avoid defects such as cavities or air bubbles, so as to guarantee the integrity and sturdiness of the prefabricated floor slab.

Finally, demold and shape. After the cement dries and solidifies, knock off the surrounding wooden boards, and what remains is the prefabricated floor slab. At this time, the prefabricated floor slab has already possessed a certain strength, but it still requires subsequent curing treatment to further improve its performance.

Method 2: Steel Plate Box Making Method

Step 1, build the box frame. Assemble the steel plate boxes into a square shape and use U-shaped twisted steel bars to insert around the perimeter for construction. This step provides a stable supporting structure for the subsequent arrangement of reinforcement bars and concrete pouring.

Step 2, arrange the reinforcement bars. Lay the reinforcement bars in a cross pattern across the entire layer and use binding wires to tie them precisely at the middle stones. The purpose of this is to act as a spacer, preventing the reinforcement bars from deforming during subsequent construction and ensuring that the reinforcement bars are accurately positioned in the concrete, thus effectively exerting their reinforcing effect.

Step 3, pour the concrete. Pour the concrete from the tanker into the assembled box below. During the pouring process, use a rubber ball with an iron hook to fix the cement to ensure that the concrete is filled evenly and densely.

Step 4, constant-temperature curing. Perform constant-temperature curing on the poured concrete to allow it to gradually harden and shape without interference from the external environment. Constant-temperature curing can improve the strength and durability of the concrete and reduce the occurrence of quality issues such as cracks.

Step 5, demold and remove. After the concrete reaches a certain strength, insert the hooks and press them firmly, and then use a forklift to pull out the hardened concrete prefabricated slab along with the reinforcement bars, completing the entire manufacturing process.
