How to Calculate the Erection of Construction Shoring Poles

Construction shoring poles play a critical role in providing temporary support to structures during the construction process. Proper erection of these poles is essential to ensure the safety and stability of the structure. In this article, we will discuss the calculation method for accurately determining the erection of construction shoring poles.

Step 1: Determine the Safe Working Load (SWL)

The first step in calculating the erection of construction shoring poles is to determine the Safe Working Load (SWL). The SWL refers to the maximum load that the shoring pole can safely support without experiencing structural failure. The SWL is typically provided by the manufacturer and can vary depending on the material and dimensions of the shoring pole.

Step 2: Assess the Ground Conditions

Before erecting the shoring poles, it is crucial to assess the ground conditions at the construction site. The ground should be firm and capable of supporting the load exerted by the shoring poles. Any signs of instability, such as soft or loose soil, should be addressed before proceeding with the erection process.

Step 3: Determine the Spacing between Shoring Poles

Next, calculate the appropriate spacing between the shoring poles. The spacing is determined based on various factors, including the type of structure being supported, the load distribution, and the length of the shoring poles. Generally, a spacing of 1.5 to 2 times the length of the shoring pole is recommended for uniform load distribution.

Step 4: Calculate the Total Load on each Shoring Pole

To calculate the total load on each shoring pole, you need to consider both the dead load and live load. The dead load refers to the weight of the structure and any permanent fixtures, while the live load refers to the variable loads that the structure may experience during construction.

For the dead load, determine the weight of the structure per unit area and multiply it by the projected area supported by each shoring pole. For the live load, consider the maximum anticipated load per unit area and again multiply it by the projected area.

Add the dead load and live load to obtain the total load on each shoring pole.

Step 5: Determine the Required Safety Factor

The required safety factor accounts for uncertainties in the calculation and ensures that the shoring poles can safely support the calculated load. The safety factor is typically determined based on industry standards and regulations. Commonly used safety factors range from 1.5 to 2, depending on the construction project.

Step 6: Calculate the Required SWL for Shoring Poles

To determine the required SWL for the shoring poles, multiply the total load calculated in step 4 by the required safety factor obtained in step 5.

Step 7: Select Shoring Poles with Sufficient SWL

Finally, select shoring poles with a Safe Working Load (SWL) that is equal to or greater than the required SWL determined in step 6. It is important to choose shoring poles that meet the necessary load-bearing requirements to ensure the safety and stability of the structure.

By following these calculation steps, you can accurately determine the erection of construction shoring poles. Remember to always prioritize safety and adhere to industry standards when working with shoring poles during construction.
