How To Calculate Shuttering Quantity
May 20, 2024In this blog, we will introduce the method of calculating the number of Shuttering in detail. We will discuss the use of different types of Shuttering, the basic data and preparation required, and demonstrate how to determine the Shuttering requirements for walls, columns, slabs, beams, and foundations step by step through specific calculation steps. Through the analysis of actual cases and the discussion of precautions, you will be able to more fully understand and master the calculation method of the number of Shuttering.
Before the calculation of the quantity of Shuttering, it is necessary to know some basic concepts and terms. These terms will help you to understand and apply the methods correctly in the whole calculation process. Here are some basic and commonly used terms.
The number of Shuttering is calculated according to the specific building works according to the specific building of the wall, column, wall, floor slab, beam, foundation and other parts.
The steps for calculating the number of Shuttering for the corresponding components are as follows:
Step:
Wall Shuttering calculation step to wall size: record the wall height and length.
Wall Shuttering area = height × length
Example: If the wall has a height of 3m and a length of 10m, Then the form area = 3m × 10m = 30㎡.
Deduct the area of the hole: measure the height and width of the door, window or other hole of the wall.
Opening area = height of the opening × width of the opening
Example: If a wall has a window area of 2㎡, Then the net Shuttering area = 30㎡ -2㎡ = 28㎡.
The total area of the Shuttering is: if there are several walls or there are several holes on the wall, the above steps will be repeated. Add up.
Step:
Determine the size: Measure the height, thickness and width of the column
Calculate the column perimeter: Circumference = 2 × (width + thickness)
E.g. If the column is 0.5 m thick and 0.5 m in width Perimeter = 2 × (0.5 m + 0.5 m) = 2m
Calculate form area for 1 single column: Template area = perimeter × height
E.g. Column height is 4 m, then column Shuttering area = 2m × 4m = 8 m²
Total Shuttering area: If there are multiple columns of the same size, then multiply by volume of columns
E. g. If there are 10 columns of the same size then, Total Shuttering area = 8m² × 10 = 80m²
Step:
The floor slab area is measured: the slab length and width are measured.
The floor Shuttering area is: form area = length × width.
Example: The floor slab length is 20m and the width is 10m. So, the floor slab Shuttering area = 20m x 10m = 200㎡.
In addition to the floor slab, there are beams or ribs on it, so the Shuttering area of the beams should be calculated and then summed up.
Example: There are 4 beams with a length of 10m and a height of 0.5m, so the beam Shuttering area = 4 x (peripheral x length) = 4 x (2 x (width + height) x length) = 4 x (2 x (0.3m + 0.5m) x 10m) = 64㎡.
Total Shuttering area: The total general Shuttering area = the total Shuttering area + the area of beams or ribs: 200㎡ + 64㎡ = 264㎡.
Step:
Size of the beam:Length, width, and height of the beam must be measured.
For finding out the beam's perimeter:Circumference = 2 × (width + height)
For example the width of the beam = 0.3m and the height = 0.5m. Then, the perimeter of the beam = 2 × (0.3m + 0.5m) = 1.6m.
Calculate the Shuttering area for a single beam:
Form Area = Perimeter × Length
Assume the length of the beam as 10m. Then, form area of the beam = 1.6m × 10m = 16㎡.
Total form area:
In case of several beams of the same size, the area is multiplied by the number of beams.
For example 5 beams are there of the same size, then the total form area = 16㎡ × 5 = 80㎡.
Step:
Determine the basic size: Measure the length, width and height of the foundation.
Calculation of base template area: Side Shuttering area of foundation = (2 × height × length) + (2 × height × width).
For example, foundation length 15m, width 10m, height 2m, then side Shuttering area = (2 × 2m × 15m) + (2 × 2m × 10m) = 60㎡ + 40㎡ = 100㎡.
Calculate the foundation slab Shuttering area (if required): The area of the floor = length × width.
For example: Base plate Shuttering area = 15m x 10m = 150㎡.
Total template area: Side Shuttering area + bottom plate Shuttering area = 100㎡ + 150㎡ = 250㎡.
When calculating and installing Shuttering, accuracy and safety are equally important. Here are some common problems and considerations to help you avoid common errors and improve project efficiency.
Measurement accuracy: Use a high-precision measure (such as a laser distance measure or high-precision tape measure) to measure the distance. Analyze the data and avoid errors that may affect template quantity calculations.
Drawings: Review the architectural and construction drawings and pay special attention to openings, corners, and complex shapes. Any omissions in an object may result in material waste.
Shuttering selection: Analyze the requirements and select the appropriate Shuttering (wooden Shuttering, steel Shuttering, aluminum Shuttering, etc.). Different materials are suitable for different natural or artificial conditions, as well as for different numbers of future uses.
Shuttering layout and door opening: Analyze the door and window or any other opening so that the formulas can accurately account for the real area. Subtract the materials used for the template and consider the loss required for splicing and cutting. Then, calculate the template amount based on your real parameters.
Shuttering support system: Design a reasonable support system to ensure the stability and safety of the Shuttering and avoid instability affecting construction quality and safety.
Template reuse and damage: Reasonably arrange the number of times the template is reused, pay attention to maintenance and care, and avoid deformation and damage caused by excessive use.
Construction environment: Adjust Shuttering selection and installation methods according to weather and terrain, and take necessary protective measures to deal with extreme weather.
Safety measures: Strictly abide by safety operating procedures and use protective equipment such as safety belts and helmets to ensure the safety of construction workers.
Construction personnel experience: Strengthen the training of construction personnel, improve their template installation and removal skills, and reduce improper installation and removal due to lack of experience.
Selection and application of Shuttering in construction is very important. Different Shuttering materials and forms are appropriate for different construction needs. The following is an outline of some forms of Shuttering and their characteristics, advantages and disadvantages, and its application in the construction process.
