Abstract
Abstract In the reinforced concrete frame for a building consisting essentially of columns assembled with horizontal beams and with floor units extending between adjacent parallel beams, the beams and floor units are precast for assembly on the building site. According to the invention, in order to provide a simple but strong connection between the beams and columns a bracket consisting of a hollow steel joist section embedded in a column and projecting laterally is received within a channel-shaped steel shoe embedded in the end of the beam in interfitting relation on assembly of the beams and columns. To ensure accurate alignment and eliminate possible canting of the beam a second length of channel-shaped steel section is embedded in the column above said bracket and receives a tubular steel section secured to and projecting from the end of the beam upon assembly of the shoe and bracket. A stuff bar pushed through the tubular section may serve to connect two beams similarly supported on opposite sides of a column. The shoe and tubular section are welded to reinforcing bars, while floor units of double T-shaped cross section, the ends of which rest on flanges of the beams, are also secured by welding reinforcing elements thereof to reinforcing bars extending laterally from the beams.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
118 words
In or for a building frame, a reinforced concrete column, a bracket consisting of a hollow steel section embedded in and projecting laterally from said column, a length of channel-shaped steel section embedded in said column and projecting laterally therefrom above said bracket, a reinforced concrete beam for assembly with said column perpendicularly thereto, a steel shoe of inverted channel shape embedded in the end of said beam and open of access from below, a tubular steel section secured to and projecting from the end of the beam above said shoe, said shoe receiving said bracket in interfitting relation and said channelshaped steel section receiving said tubular section in interfitting relation upon assembly of said column and beam.
Claim 2
Dependent Claim
118 words
In or for a building frame, a reinforced concrete column, a bracket consisting of a hollow steel section embedded in and projecting laterally from said column, a length of channel-shaped steel section embedded in said column and projecting laterally therefrom above said bracket, a reinforced concrete beam for assembly with said column perpendicularly thereto, a steel shoe of inverted channel shape embedded in the end of said beam and open of access from below, a tubular steel section secured to and projecting from the end of the beam above said shoe, said shoe receiving said bracket in interfitting relation and said channelshaped steel section receiving said tubular section in interfitting relation upon assembly of said column and beam.
Claim 3
Dependent Claim
46 words
In or for a building frame as claimed in claim 1, reinforcing bars extending as stirrups between and welded to the shoe and to the tubular steel section in the end portion of a beam, the beam also having longitudinal reinforcing bars welded to the shoe.
Claim 4
Dependent Claim
146 words
In or for a building frame, a reinforced concrete column, a bracket consisting of a hollow steel section embedded in and projecting laterally from said column, a length of channel-shaped steel section embedded in said column and projecting laterally therefrom above said bracket, a reinforced concrete beam for assembly with said column perpendicularly thereto, a steel shoe of inverted channel shape embedded in the end of said beam and open of access from below, a tubular steel section secured to and projecting from the end of the beam above said shoe, said shoe receiving said bracket in interfitting relation and said channel-shaped steel section received said tubular steel section in interfitting relation upon assembly of said column and beam, and a stuff bar inserted through said tubular steel section for contract with said channel-shaped steel section and secured at opposite ends to the beam and column.
Claim 5
Dependent Claim
146 words
In or for a building frame, a reinforced concrete column, a bracket consisting of a hollow steel section embedded in and projecting laterally from said column, a length of channel-shaped steel section embedded in said column and projecting laterally therefrom above said bracket, a reinforced concrete beam for assembly with said column perpendicularly thereto, a steel shoe of inverted channel shape embedded in the end of said beam and open of access from below, a tubular steel section secured to and projecting from the end of the beam above said shoe, said shoe receiving said bracket in interfitting relation and said channel-shaped steel section received said tubular steel section in interfitting relation upon assembly of said column and beam, and a stuff bar inserted through said tubular steel section for contract with said channel-shaped steel section and secured at opposite ends to the beam and column.
Claim 6
Dependent Claim
150 words
In a building frame a reinforced concrete column, a bracket consisting of a hollow steel section embedded in and projecting laterally from opposite sides of said column, a length of channel-shaped steel section embedded in and projecting laterally from opposite sides of said column above said bracket, a pair of reinforced concrete beams for assembly with said column perpendicularly thereto, a steel shoe of inverted channel shape embedded in the end of each of said beams and open of access from below, a tubular steel section secured to and projecting from the end of each beam above said shoe, each of said shoes receiving said bracket in interfitting relation and said channel-shaped steel section receiving each of said tubular steel sections in interfitting relationship upon assembly of said column and beams, and a stuff bar inserted through said tubular steel section and secured at opposite ends to the respective beams.
Claim 7
Dependent Claim
150 words
In a building frame a reinforced concrete column, a bracket consisting of a hollow steel section embedded in and projecting laterally from opposite sides of said column, a length of channel-shaped steel section embedded in and projecting laterally from opposite sides of said column above said bracket, a pair of reinforced concrete beams for assembly with said column perpendicularly thereto, a steel shoe of inverted channel shape embedded in the end of each of said beams and open of access from below, a tubular steel section secured to and projecting from the end of each beam above said shoe, each of said shoes receiving said bracket in interfitting relation and said channel-shaped steel section receiving each of said tubular steel sections in interfitting relationship upon assembly of said column and beams, and a stuff bar inserted through said tubular steel section and secured at opposite ends to the respective beams.
Claim 8
Dependent Claim
64 words
In a building frame as claimed in claim 4 a series of reinforced concrete beams and columns assembled together, said beams having bottom flanges extending laterally, reinforced concrete floor units of double T-shaped cross section supported at their ends upon said flanges and reinforcement bars extending laterally from the beams and welded to exposed portions of reinforcement bars partly embedded in the floor units.
