Shoring is used in construction and temporary emergency services to provide support for unsafe building structures, vessels, or trenches that are in a weakened state or in danger of collapse. The support beams may run parallel, angled, or vertical to the infrastructure when a repair needs to be made for cracked walls, debris removal, uneven foundation settlements, or unsafe crumbling of building materials. The most reliable methods include raking, flying, and dead shoring.
What Is Raking Shoring?
Raking shoring is a temporary method of securing an unsafe structure or wall which normally uses scaffolding to bear the brunt of the weight. It helps stabilize structural integrity by providing a sideward method of support. It is typically used when buildings adjacent to a structure need to be torn down or when new entryways need to be constructed which follows planning regulations.
A raking shoring uses rakers, wall plates, sole plates, cleats, bracing, and needles. Rakers are inclined at a 45 to 75-degree angle with the sole plate embedded in the ground without the use of wedging since it tends to create an unstable environment in danger of collapse. For tall buildings, a rider raker will also be used. The size and incline depend solely on the wall thrust sizing.
What Is Flying Shoring?
Flying shoring is used primarily to support the walls between two structures where a middle structure will be torn down and reconstructed. Any unsafe building that does not have shoring that reaches the ground use the flying shoring as a primary method of support and stability.
Flying shoring uses horizontal shores, wall plates, cleats, needles, and struts for incline. The wall plates are attached to the wall ensuring the building gets the proper amount of support it needs.
The horizontal strut then is placed in between wall plates which the cleats and needles support. The inclined struts receive their primary support from the needle tops and straining pieces at the bottom which secures the shore horizontally. With wider wall struts, a horizontal shore will not provide a stable area, so a constructed framework will achieve the same flying shore functions.
What Is Dead Shoring?
Dead Shoring is a method that upright provide and distribute support on roofs, flooring, and walls when the lower part of the building façade has been or will need to be removed to build a new entryway. It is also used to rebuild a crumbling wall or cracked infrastructure. It is normally also the best method to repair a load bearing that no longer is safe or stable for construction.
The dead shore method is a combination of posts and beams that provide support for the structure’s weight above ground which transfers it to the foundation. Construction workers open the wall by cutting holes for beams or girders that distribute the weight accordingly. Beams are then inserted depending on the material used to build by placing dead shores on both ends of the wall. The needles, constructed of either steel or wood, will then carry the full weight of the load.
