Apparatuses and methods for constructing a concrete structure using precast concrete components

A method for making a structure comprising:

• providing at least one precast concrete column having a top surface;
• disposing a bottom surface of a precast concrete column cap on the top surface of the at least one precast concrete column, the precast concrete column cap having a first side surface, a second side surface opposite and spaced apart from the first side surface, and a top surface opposite and spaced apart from the bottom surface, wherein at least one of the first side surface or the second side surface defines a shear key interface;
• and
• coupling a precast concrete floor section to the precast concrete column cap, the precast concrete floor section having a first side surface and a second side surface opposite and spaced apart from the first side surface, the second side surface of the precast concrete floor section being coupled to the first side surface of the precast concrete column cap,
• wherein the precast concrete column cap further comprises one of an embedded first assembly or an embedded second assembly, and the precast concrete floor section further comprises an other of the embedded second assembly or the embedded first assembly,
• wherein the embedded first assembly includes a female tapered threaded portion, wherein the embedded second assembly defines a channel and includes at least one rod disposed within the channel, each rod having a first portion and a second portion, wherein the second portion of the rod is axially extendable out of the channel of the embedded second assembly, wherein the second portion of the rod defines a male tapered threaded portion, and
• wherein the female tapered threaded portion is configured to receive the male tapered threaded portion of the rod such that the male tapered threaded portion of the rod is threadable into the female tapered threaded portion to couple the rod to the embedded first assembly.
