Definitions

  • This invention relates to a device for the transfer of loads from floors to columns in the construction of a building
  • the second method of building involves the use of a steel frame.
  • the concrete floors are supported by a steel frame and are carried on steel columns.
  • a cylindrical form gives the smallest section proportion available for a given load.
  • this method of providing an entire steel supporting structure has the disadvantage compared with the first method in that the overall floor construction depth is far greater.
  • these devices are meant for use with concrete columns.
  • the structural steel sections in these devices act as short cantilevers. Being essentially flexural members; they tend to require heavy sections. Also they bear either directly on the column or they are located close to the column perimeter. In the former position they take up space which would otherwise be utilised for the vertical reinforcement in the concrete columns. This necessitates an increase in the column size. When placed around the column, the bearing surface for the cantilevers is not well defined and therefore they act at a reduced efficiency.
  • Such devices can be applied to rectangular profiled steel sections, but not to circular hollow steel sections.
  • the invention seeks to provide an arrangement which will enable the transfer of loads and moments from a reinforced concrete floor to a circular section steel column.
  • a device for connecting concrete floors to circular steel columns comprises a steel frusto-conical element for positive attachment to a cylindrical steel column intended to pass therethrough and for embedding within and/or being placed beneath a concrete floor for carrying the said floor.
  • the device is so constructed that the dominant stresses in its parts are in-plane membrane stresses.
  • the device may comprise a hollow conical frustum attached to a sleeve which extends through the narrow end of the frustum and through which a cylindrical steel column is intended to pass so as to be attachable thereto.
  • a stiffening collar may be provided around the sleeve beyond the frustum.
  • a stiffening plate may be used to close generally the wide end of the frustum except for a central circular passage through which the cylindrical steel column is adapted to pass.
  • the stiffening plate may be omitted and a second frusto-conical element may be secured to the first frusto-conical element by its widest end so as to form a mirror image thereof.
  • the frusto-conical element may be welded to a cylindrical steel column which passes therethrough.
  • the invention also includes a building structure comprising a plurality of cylindrical steel columns, a floor laid therebetween and a plurality of connecting devices as claimed in any preceding claim connecting the floor to the cylindrical columns.
  • the connecting devices may be embedded in the concrete floor or may be located beneath the floor so as to support it.
  • a connecting device comprising two frustums
  • one frustum of the connecting device may be embedded in the floor while the mirror image frustum may be located beneath the floor.
  • FIG 1 there is shown a first embodiment of a device in accordance with the invention.
  • This is the basic form of device and comprises a hollow frusto-conical element 1 attached to a cylindrical sleeve 2 which passes through the apex of the element 1 so as to extend both inside and outside the element.
  • the sleeve On the inside of the element, the sleeve extends beyond the wider end of the element 1 so as to protrude therefrom as will be more dearly seen from figures 3 and 4. It is suitably attached to the element by welding. It has an internal diameter such as to achieve a dose tolerance fit to a cylindrical column on which it is to be carried and which will be referred to hereafter.
  • a stiffening collar 4 is incorporated above the junction between the apex of the element 1 and the sleeve 2, a stiffening collar 4 is incorporated.
  • the base of the element 1 is substantially closed by a stiffening plate 5 which has a central hole the diameter of which corresponds with the outside diameter sleeve 2 and is welded to both the sleeve 2 and the perimeter of the element 1.
  • the device is specially constructed so that the dominant stresses in its parts are in-plane membrane stresses.
  • the device is welded to a carrying steel column at each end of the sleeve 2.
  • Figure 2 shows a second embodiment of the invention in which the stiffening plate, 5, is replaced by a second frusto-conical element 6 complete with a second sleeve.
  • the sleeves 2 in this case are of reduced length so that they do not interfere with each other.
  • the second element 6 is seam welded to the first element 1 at their outer perimeters. As can be seen, the second element 6 is identical to the first element 1.
  • FIGS 3, 4 and 5 show some typical applications of the various embodiments of the invention above described.
  • the device is welded to a cylindrical steel column 3 by welds at both ends of its tube 2.
  • the device is located upside down as compared to figure 1 and concrete floor 7 is seated on the stiffener 5 so that the device project below the soffit of the slab and is in compression.
  • the outer diameter of the device is chosen so as to eliminate the need for shear reinforcement in the concrete floor.
  • the shear and bending moments from the floor 7 are transmitted to the circular steel column by the device.
  • the arrangement shown in figure 5 utilises the second embodiment of the invention as shown in figure 2.
  • the upper frusto-conical element 1 is embedded in the concrete floor 7 and is in tension while the lower frusto-conical element 6 is exposed below the soffit of the slab and is in compression.
