Definitions

  • the present invention relates to a method for the production of a floor structure beam of steel and concrete.
  • the invention relates to a method for the production of such a beam comprising, on the one hand, an elongate steel body, comprising a lower longitudinally extending steel plate, and a plurality of steel bolts, welded to the steel plate and extending in an upward direction from said plate and defining free spaces therebetween which extend along the entire width of the steel plate, and, on the other hand, a longitudinally extending concrete element, cast upon the steel plate and wherein the steel body is anchored by means of said bolts.
  • a floor structure beam of said kind is previously known through SE-C 520 410 .
  • This known beam constitutes a wholly prefabricated beam, which means that the concrete element is cast upon the steel plate before the beam is mounted at the desired installation place.
  • this fact has been found to cause considerable disadvantages in certain cases.
  • One such case is when it is desired, before a subsequent casting of a floor structure in situ, to place pipes, for instance sewage pipes, ventilation pipes or pipes for electric cables, in the floor structure in directions transversal to the beam.
  • pipes for instance sewage pipes, ventilation pipes or pipes for electric cables
  • DE-A-41 13 028 discloses a method of installing pipes in a steel/concrete structure and aims for a flexible installation.
  • Upper and lower steel reinforced concrete elements are arranged with an intermediate hallowed space forming chambers.
  • the intermediate space is formed by a plurality of spacers having bolts along their upper and lower opposite surfaces, which, bolts engage and secure the concrete elements.
  • the thus formed chambers are used to receive pipes.
  • the invention has for its purpose to provide an improved method for the production of a floor structure beam of the kind initially specified that makes it possible to avoid the above disadvantages.
  • the method according to the invention proposed for said purpose is primarily characterized in that the concrete element as a whole is produced by casting concrete upon the steel plate only when the steel body has been placed in the intended position therefor in a floor structure.
  • the invention eliminates the need for producing separate holes for different kinds of pipes in the beam since, once the steel body of the beam has been placed in its intended position but before any concrete element has are are been cast, said pipes are placed in the free spaces between the bolts welded upon the steel plate.
  • reinforcement bars extending in the transversal direction of the steel body and projecting laterally therefrom, may be affixed to upper portions of the steel body before the step of casting the concrete element in order then to become embedded in the concrete element during the subsequent casting of said element.
  • the concrete element of the beam may be produced integral with one or more concrete floor structure plates simultaneously cast in situ.
  • the use of reinforcement bars affixed to the steel body of the beam offers the specific advantage of making it unnecessary, as required in respect of the above mentioned known prefabricated beam, to produce the concrete element of the beam from so-called high strength concrete, i.e. a concrete of extremely high quality, but instead to produce said element from concrete of the quality normally used for casting floor slabs in situ.
  • the method according to the invention may be used for the production of floor structures comprising prefabricated hollow floor structure plates.
  • the reinforcement bars are brought to extend into cavities in prefabricated hollow floor structure plates which, before casting the concrete element of the beam, are placed resting on longitudinally extending edge portions of the steel plate, said cavities being filled with concrete, at least along the length of the portions of the reinforcement bars extending into the cavities during the step of casting the concrete element.
  • a steel body comprising also one or more longitudinally extending stiffening members, welded to said bolts and placed above the steel plate at a substantial vertical distance therefrom.
  • a steel body wherein said bolts are arranged in two parallel rows and one longitudinally extendning stiffening member is welded to each of the two bolt rows.
  • the two stiffening members may in this case be connected to each other by means of transversally extending connecting members.
  • reference numeral 10 generally designates a steel body for a floor structure beam.
  • Steel body 10 consists of an elongate steel plate 11, intended to be mounted in a horizonal position and a plurality of steel bolts 12 welded to plate 11 and extending in an upward direction therefrom and provided with enlarged heads 13 at their upper ends. Said bolts are arranged in two parallel rows which are located each at a certain distance from one longitudinal edge of plate 11.
  • FIG 2 there is shown a steel body 10' which differs from body 10 according to Figure 1 only in that it also comprises two longitudinally extending angle steel bars 14 which are welded each to one row of bolts 12 in a position located at a certain distance from plate 11. Angle steel bars 14 have for their purpose to act as stiffening members for body 10' causing a substantial increase in the bending rigidity of said body.
  • Figure 3 shows an additional modified steel body 10" which differs from body 10' according to Figure 2 only in that is also comprises a plurality of bars 15 which serve as connecting members between angle steel members 14 and extend in directions transversal to members 14 and which are welded to said members at their ends. Bars 15 have for their purpose to increase the torsional rigidity of body 10".
  • a floor structure generally designated 16, which comprises a floor structure beam produced by utilizing the method according to the invention, and two only partially shown floor structure plates 24 located at opposite sides of said beam and supported by said beam.
  • the floor structure beam comprises a steel body 10 according to Figure 1 and a concrete element 17 cast upon said steel body.
  • Floor structure 16 is produced in the following manner. Firstly, steel body 10 is placed in the desired position and supported in said position in any suitable manner. Prefabricted form members 18, consisting of steel or concrete, are then placed in positions resting upon outer longitudinally extending edge portions of plate 11 of steel body 10. Thereupon, the concrete element 17 of the beam and the floor structure plates 24 are formed in one piece by casting concrete in situ upon form members 18 and plate 11.
  • Figure 5 shows a floor structure 16' of slightly modified design.
  • floor structure 16' is assumed to be produced by casting concrete plates 24 upon a form (not shown) which may be removed after the casting operation and upon which also the steel body 10 of the beam is supported during the simultaneous casting of plates 24 and concrete member 17. Therefore, any form members remaining after the casting operation and corresponding to members 18 of floor structure 16 according to Figure 4 will not exist in floor structure 16' according to Figure 5 .
  • FIG. 6 shows a floor structure 16" of so-called HDF-type which comprises a floor structure beam produced by the method according to the present invention and two only partially shown prefabricated hollow slab plates 21 supported by said beam. Plates 21 are supported resting on longitudinally extending edge portions of the steel plate 11 of the beam and are provided with through cavities 22 into which pipes 19 and reinforcement bars 20 can be inserted in order then to be fixed within said cavities by filling the cavities with concrete at least along the length of the portions of reinforcement bars 20 extending into cavities 22 during the step of casting a concrete element 17 upon steel plate 11 and around bolts 12.
