Various implementations include methods and apparatuses for constructing a concrete structure. In one implementation, a structure includes a pre-cast concrete column section and a pre-cast concrete beam section. The column section includes an embedded first assembly with a threaded rod, and the beam section includes an embedded second assembly defining a channel for receiving the threaded rod. Grout is fed through a joint between the column and beam sections into the second assembly to couple the threaded rod with the second assembly. The grout is urged through the joint and the second assembly by gravity and by applying vacuum suction to a grout port defined by the second assembly. The grout port extends between the channel of the second assembly and an external face of the beam section.

In one aspect, a reinforcing assembly includes one or more longitudinally-extending bars having a first end a second end opposite the first end. The reinforcing assembly also includes multiple downwardly-extending working members each independently connected at a top of the working member to at least one of the one or more bars. The working members are oriented diagonally with respect to a longitudinal axis extending along the one or more bars.

An anchor rod support comprises a support having a floor and legs extending downwardly from the floor with openings between the legs; and the support including threads for attaching thereto an anchor rod.

A prong is configured for use with a concrete reinforcement element and includes first and second legs positioned opposite first and second sides of the prong and a bridge portion connecting distal ends the legs, where the bridge portion forms a first end of the prong. The legs extend from the bridge portion to a second end of the prong opposite the first end, and each of the legs has a proximal end at the second end of the prong. The proximal end of the first leg is bent toward the second leg, and the proximal end of the second leg is bent toward the first leg, such that the proximal ends of the legs overlap each other. Inner surfaces of the proximal ends of the legs define engagement surfaces configured to engage a tie wire, enabling the proximal ends to be connected to the tie wire.

Devices, systems, and methods for constructing post-tensioned concrete slabs in a new floor construction that has a reduced gap distance between the slabs. The devices, systems, and methods can improve project construction time by reducing the time delay in accessing the floor underneath the slabs due to safety and/or weather conditions.

A concrete dowel slip tube assembly is provided for use in maintaining a planner consistency of a cured concrete slab formed on a support surface. The assembly comprises a plurality of elongate slip tubes, each having a length dimension and a tubular hollow interior compartment. Dowels are slidingly engageable to the hollow interior compartment to allow for translation along the interior compartment. A support frame defines a plurality of integral slip tube retaining members, disposed at evenly spaced locations along the support frame, the retaining members being configured to receive and engage associated slip tubes to the support frame in a common defined orientation. The support frame and the retaining members are formed as a unitary construction.

In one aspect, a reinforcing assembly includes one or more longitudinally-extending bars having a first end, a second end opposite the first end, and a midpoint between the first and second ends. The reinforcing assembly also includes multiple downwardly-extending working members each independently connected to at least one of the one or more bars. The working members are oriented diagonally with respect to a longitudinal axis extending along the one or more bars. The working members connected to the one or more bars between the first end and the midpoint are angled in a different direction than the working members connected to the one or more bars between the second end and the midpoint.

A construction module for a structure, comprising: a formwork member that includes a base, a pair of parallel side walls that extend upwardly from the base, and a pair of parallel end walls. The base, the side walls and the end walls define a cavity for reinforcement and concrete. A reinforcement member includes an upper portion and a lower portion. When the reinforcement member is located in the cavity and concrete fills the cavity, the lower portion of the reinforcement member and the concrete define an elongate beam.

Various implementations include methods and apparatuses for constructing a concrete structure. In one implementation, a structure includes a pre-cast concrete column section and a pre-cast concrete beam section. The column section includes an embedded first assembly with a threaded rod, and the beam section includes an embedded second assembly defining a channel for receiving the threaded rod. Grout is fed through a joint between the column and beam sections into the second assembly to couple the threaded rod with the second assembly. The grout is urged through the joint and the second assembly by gravity and by applying vacuum suction to a grout port defined by the second assembly. The grout port extends between the channel of the second assembly and an external face of the beam section.

A construction formed of column and a beam, where the beam has top and bottom flanges coupled to the column by a lateral bracing system, and a web between the top and bottom flanges. The lateral bracing system may include a column-mounted plate including a horizontal portion and a vertical portion, the vertical portion affixed to the column. The beam may be coped at top and bottom edges of the web to prevent binding of the beam flange with the column-mounted plate upon rotation of the beam relative to the column.
