Embodiment Construction

[0037]A prefabricated welded cage 104 is shown in FIG. 1. The prefabricated welded cage 104 includes a number of vertical reinforcing bars 106. A continuous tie 108 extends around the vertical reinforcing bars 106. Although only one continuous tie is shown in FIG. 1, it will be understood that the welded cage 104 includes a plurality of continuous ties 108 which are placed at vertical intervals around the vertical reinforcing bars 106. Preferably, the plurality of continuous ties 108 are spaced at even intervals along the height of the vertical reinforcing bars 106. A. plurality of shear ties 110 extend generally horizontally between the vertical reinforcing bars 106. The welded cage 104 is sized and shaped for shipping.

[0038]The structure of one of the plurality of continuous ties 108 is shown in FIG. 2. The continuous tie 108 shown in FIG. 2 is a single piece of reinforcing steel that forms a closed loop with, for example, ends that overlap.

[0039]In FIG. 3, a prior art design for ...

Abstract

There is provided a reinforcing steel structure for use in a concrete building wall. The structure includes one or more prefabricated, welded cages having vertical reinforcing bars. A plurality of continuous ties extends around the vertical reinforcing bars and a plurality of shear ties extends generally horizontally between the vertical reinforcing bars. Each welded cage is sized and shaped for shipping and said structure can be formed onsite from a plurality of said cages lapped together. Concrete is added to the reinforcing steel structure to form a concrete building wall.There is also provided a reinforcing steel structure for use in a concrete building transfer or raft slab. The structure includes one or more prefabricated, welded beams. The prefabricated, welded beams have a top beam layer and a bottom beam layer, each having horizontal reinforcing bars, and a plurality of continuous ties extending generally vertically around the top and bottom beam layers. Each welded beam is sized and shaped for shipping and said structure can be formed onsite from a plurality of said beams lapped together. Concrete is added to the reinforcing steel structure to form a concrete building slab.

Description

FIELD OF THE INVENTION[0001]This invention relates generally to the broad field of reinforced concrete and more particularly to the steel, or rebar used to reinforce the concrete. More particularly, this invention relates to methods and apparatus for constructing and installing rebar used in concrete construction.BACKGROUND OF THE INVENTION[0002]Reinforced concrete is a well known and widely used building material which is used in building, bridges, roads, tunnels and other structural construction projects. Essentially the concrete, which is strong in compression but has no strength in tension, is reinforced with steel rods which pass through the zones of tension in the structural element. Engineers design the structural components; calculate the forces which will be generated by the structure, which may be carrying dynamic or static loads or both; and then develop a rebar plan to provide enough rebar reinforcement in the regions of the concrete structure where tension forces may be...
