Definitions

  • Prefabricated concrete floor elements comprise elongated, flat bases that serve as ceiling elements on the floor below and parallel, spaced beams. The elements are placed between parallel horizontal supports carried by vertical pillars. A concrete floor is placed over the upstanding edges of the beams and secured thereto to complete the assembly.
  • the invention relates to a concrete floor including prefabricated floor elements supported by support means which floor elements have spaced apart beams secured to a bottom panel constituting a ceiling,
  • the object of the invention is to enable the use of long beams and thus long spans and simultaneously enhance the possibility of making electrical, sanitary, etc. installations.
  • Buildings, particularly business buildings, hospitals, etc. must have frameworks which do not interfere with the rational use of the localities of the building and furthermore walls within the buildings must be removable in order to amend room sizes.
  • the first mentioned requirement could be met by providing a vertical supporting framework comprising pillars having a mutual distance as great as possible.
  • the objects of the invention are achieved by securing the upper end faces of the beams to an upper concrete panel which extends between the support means so as 'to obtain a static connection between the beams and the concrete panel, thus enabling the use of long, relatively weak beam elements.
  • FIG. 1 illustrates the underside of a concrete floor
  • FIGS. 2 and 3 are vertical sections along lines A- and BB, respectively, in FIG. 1,
  • FIG. 4 is a vertical section along line C-C in FIG. 1,
  • FIG. 5 is a section through a prefabricated floor element
  • FIGS. 6, 7 and 8 illustrate sections through the floor element secured to the upper concrete panel and FIG. 9 is a plane view of the arrangement in FIG. 8.
  • the system of supporting pillars is denoted l.
  • the load carrying main beams 2 are positioned on the pi]- lars l.
  • the main beams 2 carry the prefabricated floor elements 3, which are shown in section in FIG. 5 and generally comprise a flat panel 4 with upwardly directed beams 5.
  • the beams have ends at a distance from the ends of the floor element and a cavity 6 is, thus, obtained between the beams 5 and the main beams 2.
  • the floor elements are selfsupporting to allow transport and handling thereof. They are rather weak and must be provisionally supported until the entire floor has been mounted. After positioning the floor elements 3, the cables and conduits 7 could be placed between the beams 5. The cables or conduits 7 could also be extended between separate floor elements through the cavities 6. Conduits or cables could also extend to the opposite sides of the main beams 2 by providing holes 8 in the main beams.
  • the spacing between the beams 5 may thereafter be filled with an insulation till 9, such as granulated foam plastics, cork granules, mineral wool, etc., and a load carrying concrete panel 10 cast on the fill and the beams 5.
  • an insulation till 9 such as granulated foam plastics, cork granules, mineral wool, etc.
  • a load carrying concrete panel 10 cast on the fill and the beams 5.
  • a static connection between the floor element 3 and the panel 10 is obtained by reinforcing rods or the like.
  • the reinforcing or anchoring means could be provided in opening in the panel 10 which openings are filled with concrete.
  • the filling material is at least partly substituted by form material 9, such as boards, corrugated plates etc.
  • concrete panel 10 cast on the beams is substituted by prefabricated concrete panels 12 provided with recesses 13 in order to enable concrete statically to join the panels 12 to the beams 5.
  • Concrete 14 is cast into the recesses and anchoring means or reinforcement rods could be inserted into the recesses.
  • each floor element including a planar lower panel which forms the ceiling of the floor below and a plurality of spaced beams integral with and extending across the upper surface of the lower panel in a direction generally transverse to the support beams, the length of each beam being less than the distance between the support means to thereby provide a gap between the end of each beam and the adjacent support means to accommodate electrical cables, pipes, etc., extending across adjacent floor elements, the improvement characterized by:
