SECTION 1 — DEFINITIONS (Continued)
1.26 Locking Device — A device used to secure components.
1.27 Post Shore or Pole Shore* — Individual vertical member used to support load.
1.28 Reshoring — The construction operation in which the original shoring is adjusted or replaced to support partially
cured concrete and other imposed loads.
1.29 Roller Assembly — The mechanism of the rolling shore bracket that allows movement of the deck form across it.
1.30 Roller Beam — The primary load supporting member of the deck form supported by the rolling shore bracket.
1.31 Rolling Shore Bracket — A prefabricated welded or cast structural unit affixed to a wall or column and capable
of supporting the loads transmitted from a deck form, and also the rolling load transmitted by the movement of
the deck form.
1.32 Roll-Out — The act of moving the deck form across the roller assemblies to its position for next use or for crane
pickup.

1.33 Sate Leg Load — The ultimate leg load divided by the appropriate safety factor.
1.34 Sheathing — The material forming the contact face of forms; also called lagging or sheeting.
1.35 Shore Heads — Flat or formed members placed and centered on vertical shoring members.
1.36 Shoring or Falsework' — The elements used, excluding the formwork.to support fresh concrete and/or
structural members during construction.
1.37 Shoring Layout — An engineering drawing prepared prior to erection showing arrangements of equipment for
proper shoring based on manufacturer's recommended use and loading criteria.
1.38 Sill or Mud Sill* — A member (usually wood) designed to distribute the vertical shoring loads to the ground or
slab below.
1.39 Spacing — The horizontal center-to-center distance between support members.
1.40 Stringers or Ledgers' — Horizontal structural members which directly support joists.
1.41 System Scaffold Shoring — An assembly used as a load-carrying structure, consisting of fabricated columns,
braces, ties, adjustable bases, and other components which connect to the uprights to form the structure.
1.42 Towers — A composite structure of frames, braces, and accessories.
1.43 Tube and Coupler Shoring—An assembly used as a load-carrying structure, consisting of tube or pipe which
serves as posts, braces and ties, a base supporting the posts, and special couplers which serve to connect the
uprights and join the various members.
1.44 Ultimate Load — The minimum load which may be placed on a structure causing failure.
* These terms, and others so marked, may be used synonymously.
