Example text
A lecture section concentrates on the proper size-up and the correct step-by-step erection of the various shores designed for installation on the interior of collapsed structures. This is a basic class showing the most common types of shores a rescue team normally erects in a major collapse scenario. This is an intensive, hands-on course; and the students are tested on the proper erection of the various shores. Hands-on exterior shoring-16 hours This is a two-day class designed to present an exhaustive discussion of the proper exterior shoring techniques needed to safely construct all the types of exterior shores generally needed to conduct safe rescue operations and stabilize the exterior of the structure.
In the construction of raker shores, the nail patterns on these cleats and gussets are very important, as it is the number of nails that provides the proper holding power. In the use of plywood gusset plates that are normally 3/4 in. thick, 8d nails are generally sufficient. In the 2x4 or 2x6 cleats used on the raker shores, 16d nails should be used. Duplex, or double- header nails as they are sometimes called, can be used for training purposes. These nails are easily extracted from the material with little damage, enabling the rescue team to utilize the same lumber over again, thereby making hands-on training more economically feasible.
Limiting the length of posts or struts keeps the strength at the most efficient levels. That is one of the reasons to brace shoring systems. The longer and thinner the element is, the less weight it can support. By center bracing or lateral bracing these elements, shoring teams get the best use of the strength of the lumber. In most cases, the ratio of the posts should be kept at a maximum of 50-to-1. 5 in. 5 in. , which equates to roughly 14 ft. This would be the maximum length to use to shore up something lightweight.
