Definitions

  • the present invention relates to an improvement in composite columns comprising a core in the form of a steel post contained within a steel tube, said core and said steel tube being intended to coact statically with one another and with concrete cast therebetween.
  • a common type of composite column comprises a steel tube filled with concrete.
  • the load from the floor beams can be transferred to the column through connections welded to the steel tube. These connections must be anchored effectively in the concrete in order to ensure that the concrete will also participate in taking up the load applied. This can only be achieved with dif ⁇ ficulty.
  • storey-high columns i.e. col ⁇ umns which extend vertically through the extent of solely one storey.
  • Such columns are normally provided with robust base and top plates, which enable loads to be distributed between steel and concrete.
  • One advan ⁇ tage with storey-high columns is that the floor beams can be extended continuously over the columns, there ⁇ with improving the load bearing capacity of the beams.
  • One drawback with storey-high columns resides in the necessity to fit the beams with complicated devices which will enable the load exerted by an overlying column to be transmitted through the beams without subjecting the beams to compression.
  • An object of the present invention is to provide an improved composite column which el inates the aforesaid drawbacks of known composite columns.
  • the characteris- tic features of the inventive column are set forth in the following Claims.
  • the present invention is manifested in a jointing and position-fixating sleeve which facilitates the work of joining columns together and also guarantees precise positioning of the steel post within the steel tube before and when casting concrete therein. Furthermore, the sleeve provides effective static coaction between the steel post and the steel tube and the concrete cast therebetween. Because of its configuration, the sleeve also forms a support which enables a floor beam to be layed so that it continues over the column, while ena ⁇ bling, at the same time, the steel post of the com ⁇ posite column to project above the plane of the floor beam, for simple and ready connection of the column above, such as to obviate the need of complicated de ⁇ vices on the floor beams for transferring the vertical loads from said column above.
  • FIG. 1 is a partial, schematic side view in cross- section of a composite column constructed in accordance with one preferred embodiment of the invention, and more specifically the base end of the column;
  • Fig. 2 is an end view of the composite column shown in Fig. 1;
  • Fig. 3 is a partial, schematic side view in cross- section of the top end of the column illustrated in Fig. 1;
  • Fig. 4 illustrates schematically, and in side view, a method of manufacturing a composite column, and more specifically a manner of mounting to each end of a post of cruciform cross-section a base ring and top ring each of which functions as jointing and position- fixating sleeve;
  • Fig. 5 is a schematic side view, in cross-section, which illustrates a method of jointing an upper com ⁇ posite column to an underlying, erected composite column subsequent to laying a floor comprising beams which rest on the top ring of the bottom column, and after filling the steel tube with concrete.
  • Figs. 1 and 2 illustrate a preferred embodiment of an inventive composite column 1, comprisng a core in the form of a steel post, e.g. a post 2 of cruciform cross- section, and a steel tube 3 which encircles the post. Subsequent to casting concrete between these members, said members are intended to coact statically with one another and with the concrete 4 cast therebetween. The concrete can be cast between said members either in a separate operation, or in conjunction with casting a concrete floor 5 (Fig. 5), or when using concrete for joining in a prefabricated floor structure.
  • the ring 9 has extending therefrom a number, preferably 8, of pairs of mutually parallel plates or fingers 10, which extend towards the centre of the ring and which terminate at a given distance therefrom, said plates 10 having an extension in the longitudinal direction of the ring 9 such that the plates, when forming a base ring, will project slightly beyond, e.g.
  • the steel tube 3 extends into abutment with respec- tive rings 9 and is secured in position, e.g. by weld- ing.
  • the position of the cruciform post 2 in the steel tube 3 is determined exactly by means of the plates 10 on the base and top rings 9, both before and when cast ⁇ ing concrete into the tube.
  • the plates 10 on the jointing and position-fixating sleeve 8 extend mutually parallel in pairs, in a direction towards the centre of the sleeve 8 and the ring 9, at a mutual distance apart which corresponds to the thickness of the legs 16 of the cruciform post 2 used.
  • the plates 10 may be pro ⁇ vided with a slot 17, so as to enable the plates 10 to be deformed more redily and to be adapted to a cruci ⁇ form post 2 of smaller dimensions.
  • the jointing and position-fixating sleeves 8 are fitted into the end parts of the steel tube 9, with the cruciform post 2 fixated by the weld 15 and with plates 10 displaced positionally in the longitudinal direction of the steel tube 3 such as to form a male and a female end where, in the illustrated embodiment, the female end is lo ⁇ cated at the base end 6 of the column 1 and the male end is located at the top end 7 of said column.
  • the top end 7 of the cruciform post 2 projects beyond the outer edge 11 of the top ring 9 through a distance which corresponds to the depth of distance from the outer edge 11 of the base ring 9 to the end edge 18 of the cruciform post 2 at the female or base end 6 plus the thickness of the floor 5 to be carried.
  • the plates 10 terminate at the top end 7 of the column 1 flush with the outer edge 11 of the ring, thereby providing a support for the floor beams 19 (Fig. 5).
  • the plates 10 mounted on the sleeve 8 which functions as a base ring at the base end 6 of the column 1 project slightly downwrd ⁇ , beyond the outer edge 11 of the base ring 9, as mentioned above.
  • top ring 9 at the top end 7 of the co po- site column 1 has a greater diameter in relation to the extension of the cruciform post 2
  • one or two mutually parallel floor beams 19 can be laid continuously over and supported by the support formed by the top ring 9 on both sides of the cruciform post 2, which increases the load bearing capacity and rigidity of the floor beams 19 while enabling, at the same time, the cruci ⁇ form post 2 to extend continuously above the floor beams 19 for the purpose of joining the underlying column to the cruciform post of the overlying column and therewith enabling load to be transmitted from the overlying column 1 without requiring the provision of complicated and expensive devices on the beams 19 for transferring the load between the columns.
  • a cruci ⁇ form post 2 of given dimensions is suspended from an overhead crane or like apparatus, as as to terminate at a given distance from an underlying support surface.
  • a jointing and position-fixating sleeve 8 which forms a base ring and a further sleeve which forms a top ring are pressed onto the ends 6, -7 of the post of cruciform cross-section in a manner to form the aforesaid male and female configurations, whereafter the post 2 is lowered onto the support surface and rolled or rotated so as to enable the plates 10 on the rings 9 to be welded onto the sides 13 of the cruciform post 2.
  • the plates 10 can be deformed to coincide with cruciform beams of smaller dimensions, by pressing the plates 10 into abutment with the walls 13 of the post 2 and welding said plates to said walls, this de ⁇ formation of the plates being facilitated by the afore ⁇ said slots 17.
  • the steel tube 3 is then placed over the cruciform post 2 and welded to the base and top rings.
  • the column 1 can now be erected in position on the building site and filled with concrete, which can either be carried out separately or when casting a concrete floor or when using concrete for joining a prefabricated floor structure.
