Adjustable supports are an emerging product used for laying floors. They consist of many small supports, each of which can independently adjust its height and be placed in different positions as needed. These supports are usually fixed on rubber or other types of pads to prevent damage to the floor.

There are many benefits to using adjustable supports, such as providing better drainage and ventilation, making the floor more stable and able to withstand greater pressure, and allowing for easy replacement of damaged flooring. In addition, adjustable supports are easy to install and do not require any adhesives, drilling, or screws to fix the floor.

However, it's crucial to calculate the required number of supports correctly. If there are too few supports, the floor may warp, become defective, or become damaged. Conversely, using too many supports will increase the project's cost and affect its stability.

To properly calculate the required number of supports, you first need to determine the size and shape of the ground. You can then use an online calculator or manually calculate the number of required supports and the size of the necessary pads. When performing calculations, factors such as ground weight, required support height, and expected load should be considered. For example:

Suppose there is a 10-foot long and 8-foot wide terrace that needs to be tiled with 20-inch x 20-inch tiles. The support height is 2 inches, and the load per square foot is 250 pounds. Then we can follow these steps to calculate:

Calculate the total area

First, calculate the total area of the terrace: 10 feet x 8 feet = 80 square feet.

Calculate the area of each tile

Since each tile is 20 inches x 20 inches, the area of each tile is (20/12) feet x (20/12) feet = 2.78 square feet.

Calculate how many tiles are needed

Divide the total area by the area of each tile to get the number of tiles needed: 80 square feet ÷ 2.78 square feet = 28.78 tiles. We need to round up to 29 tiles since we can't buy fractional tiles.

Calculate the area that each support can bear

We need to calculate how much area each adjustable support needs to bear. Assuming each support can withstand a maximum load of 1000 pounds, we can calculate its load-bearing capacity by dividing its maximum load capacity by the load per square foot: 1000 pounds ÷ 250 pounds/square foot = 4 square feet.

Calculate how many supports are needed

Divide the total area by the area that each support can bear to find the number of supports needed: 80 square feet ÷ 4 square feet = 20 supports. Note that this is just a rough calculation, and more or fewer supports may be required depending on the specific circumstances.

Through these calculations, we can preliminarily determine the required number of supports and select suitable types and specifications. However, continuous adjustments and corrections will still need to be made during installation. Edge positions may require more supports, and there may be some consumption during construction. If you need to determine the required number of adjustable supports, it's best to consult professionals or manufacturers to calculate and evaluate based on specific circumstances to ensure the stability and safety of the floor laying.
