Definitions

  • 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.
  • 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.
  • brackets upon the columns to receive and support the ends of the beams whichextendfrom column to column.
  • a bracket upon a column to support the end of a beam'is constructed by a steel joist section which may be of inverted channel shape, but is preferably tubular, portion being embedded in the reinforced concrete column while a portion projects laterally to;
  • FIG. 9 shows to a reduced scale and diagrammatically a suitable arrangement of the reinforcement provided in a beam and'in the end portion of a floor element resting thereon.
  • steel shoe which is at least partially embedded in the concrete of the end of the beam but is open of access on the underside. It is preferably welded to longitudinal reinforcement bars of the beam. If the column is intended to support beams on both sides thereof the bracket section passes, completely through the column, a portion projecting on opposite sides thereof to provide the beam supports.
  • means are provided at the end of the beam, spaced somewhat from the. shoe above referred to, and adapted to register with corresponding means provided upon the column to ensure a predetermined alignment and eliminate any possible twisting. or lateral tilting of the beam.
  • Such means advantageously consist of interfitting steel members, preferably ashort length of channel-shaped or tubular rolled steel section embedded in the column with its longitudinal axis horizontal and with one or each end projecting laterally from the side of the column and adapted to cooperate in interfitting relation with a corresponding tubular or channel-shaped steel section cast in the end of the beam.
  • the arrangement is such that when placing the end of a beam in position so that the shoe restsupon the bracket the beam is first suspended with its end more or less in contact with the column, but above the desired final position, and as the beam is lowered the shoe comes to rest upon the. bracket at the same time as the members constituting the registering means above referred to come togetherin nesting relation, one within the channel ofthe other.
  • the floors of the building preferably consist of reinforced concrete members of double T-shaped cross section, the ends of which rest on laterally extending flanges of the beams, the latter having laterally projecting reinforcement bars-which are welded to the upper projecting portions of stirrups of reinforcement bars embedded in the end portions of said floor members.
  • FIG. 1 is an isometric view of portion of the floor and frame ofa building as seen from below FIGS. 2,3 and 4 are similar isometric views showing respective portions of FIG. 1 in unassembled condition
  • FIG. 5 is an isometric view from above of the end portion of the beam shown in FIG. 3,
  • FIG. 6 is a similar isometric view of a column and beam in assembled relation
  • FIG. 7 is an isometric view corresponding to FIG. 2, but to a lar er scale showing in full lines the metal members embedded serves to stiffen the structure.
  • the columns 1 are of substantially T-shaped in horizontal cross .section, while the beams 2, at least those which. are located at the sides of the frame, are of L-shaped cross section so as to provide ledgesor rabbets to receive the ends of the floor plates 3. It willv be understood, however, that where horizontal beams are required to be arranged intermediately in the frame, to serve as so-called spine beams and are required to'support the ends of floor plates extending from both sides thereof, said beams will be of T-shaped cross section and arranged with the flanges at the bottom.
  • brackets or steps in the form of tubular steel sections 5 are partially embedded inthe columns 1, and where the columns are required to support beams 2 on both sides the sections 5 extend completely through the columns 1 and project on both sides as shown most clearly in FIG. 4.
  • a shoe 7 of such size asto fit snugly over the bracket 5 while a second rolled steel tube portion 8 is disposed at the top of the beam 2 and is adapted to engage the section 6 when the shoe 7 engages the step 5 on placing the beam in its assembled position in relation to'the column 1 which is to support it.
  • the sections 8 and 5 are preferably securely held in position at the end of the beam 2 by the provision of stirrups 9 (FIG. 7) welded thereto.
  • the shoe 7 is also preferably welded to the longitudinal reinforcement bars 10 of the beam 2.
  • a stuffing bar 11 is passed through the tubular member 8. It is advantageously welded to said member and also grouted to form a firm connection between the column 1 and the beams 2 on each side thereof.
  • the floor plates 3 are preferably of double T-shaped cross section, suitably reinforced and at their ends are provided with sole plates 12 adapted to sit upon corresponding bearing plates 13 provided on the flanges of the beam 2.
  • the sole plates 12 may be welded to the bearing plates 13.
  • the reinforcement in the end portions of the webs of the floor plates 3 preferably comprises stirrups 14, as shown in FIGS. 8 and 9, which at the bottom are welded to the sole plates 12 at the top project above the upper surface of the beam and are welded to reinforcement bars 15 provided for that purpose and extending laterally from the beam 2.
  • stirrups 14 as shown in FIGS. 8 and 9
  • a reinforced concrete column 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 channelshaped 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 receiving said tubular section in interfitting relation upon assembly of said column and beam.
  • 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.
  • a reinforced concrete column 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 channelshaped 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.
