What is the recommended length and width of a shoring wedge?

The recommended length and width of a shoring wedge being six times the minimum butt thickness is grounded in structural and safety considerations. A shoring wedge serves to provide support and stability during construction or repair work, especially when dealing with heavy loads and potential movement of materials. By specifying a dimension of six times the minimum butt thickness, it ensures that the wedge has adequate surface area to distribute loads effectively, thus minimizing the risk of failure or slippage.

This proportion is established to enhance the wedge's ability to resist sliding and collapse under load, which is critical given the variable conditions on construction sites. Adequate dimensions also facilitate better engagement with the surfaces they are supporting, leading to increased friction and stability. Engaging with materials that are not of appropriate size could lead to occupational hazards, including structural failure which might endanger workers and impede project progress.

Therefore, the specification of six times the minimum butt thickness for shoring wedges represents a balance between practical usability and adherence to safety protocols in construction practices.
