Definitions

  • the invention relates to a floor system, comprising a series of concrete prefab elements.
  • the invention especially relates to a floor system having spaces extending below cover elements, suitable for utility lines such as drainage, mains or such pipes, electrical or data lines, telephone lines and the same.
  • prefab elements for example for floors and walls.
  • prefab floor elements it is known to us elements comprising channels extending in a longitudinal direction through the element, for feeding utility lines and pipes through the floor. These elements are closed on both an upper and lower side. Holes are drilled through the top or bottom surface, into a channel, for leading the lines out of the channel towards a space below or above the element.
  • prefab floor elements which have beams on an upper side of a slab.
  • the slab can form the ceiling of a space below, whereas between the beams above the slab pockets are provided for the utility lines. Openings are provided through the beams, for feeding the lines in a direction perpendicular to the longitudinal direction of the beams, from one pocket to the next.
  • At the longitudinal ends of the slab cross beams are provided, between adjacent longitudinal beams, closing off the pockets at said ends.
  • a cover element is placed over the beams and slab, closing off the pockets at the top and forming a floor.
  • a disadvantage of these elements can be that the utility lines cannot easily be brought into or lead out of the pockets. Access to the pockets has to be gained through the cover elements, through the slab or through the cross beams. This is cumbersome and time consuming, Moreover, when the floor elements are placed access to the pockets may be even more restricted by walls placed below and above the cross beams.
  • WO02/35029 discloses a floor system comprising a series of parallel metal I-beams supported by a support structure. Between two adjacent I-beams tubes are provided, supported on the lower flanges of the beams. Sheet like elements are carried on the upper sides of the tubes and on the upper flanges of the I-beams, forming a floor. In the floor connecting boxes are supported, which are closed at the upper side by a lid. Plug sockets are provided in the boxes. Additionally air outlet openings are provided in the floor. In order to provide any utility lines in the floor system, such as lines to be connected to the boxes or air outlets, the sheet like elements have to be removed.
  • the invention provides a floor system according to claim 1.
  • the invention provides a set according to claim 10 and a building according to claim 11.
  • utility pipe or line or similar wording has to be understood as including at least any utilitarian provision needing pipes, hoses, cables, drains or the like provisions for transporting for example water, sewage, electricity or data.
  • a floor 100 also referred to as floor system 100 is shown in top view, comprising a series of concrete prefab floor elements 1.
  • the elements 1 are interconnected by interconnecting elements 8, as shall be discussed here after, and can span the entire width WB of a relevant part of a building 101, for example but not limited to a span of 5 metres or more.
  • the floor 100 has a length Lb, defined by the combined widths W, WA of the elements 1, 1A, 1B, whereas the floor has a width WB, defined by the length L of the elements 1, 1A, 1B.

  • an edge portion 26 is made of a material different from the concrete from which the slab and beams are formed.
  • the material of the edge portion 26 can for example be softer and/or more brittle than the concrete.
  • a wall element 27, for example but not limited to a prefab concrete element or a brick wall, can be placed on top of the top surface 11 of the cross beam 7, as for example schematically shown in fig. 2C in broken lines.
  • the edge portion 26 allows easy access into said wall element 27, easier than when part of the concrete of the beam has to be removed, for example for cables or pipes, as schematically indicated by striped line 22.
  • an edge of a beam 3, 7 or a slab 2 can be made of the same or similar material, for the same or similar purpose. Openings such as 8, 9, 19, 21 can also be made by providing such material in a position in which an opening could be advantageous, such that during use the opening can easily be created by removing part or all of said material.
  • the cover elements 17 are provided with stepped side edges too, such that these edges are close to each other at a top level, an isolating strip 23 being provided in between, whereas at a lower level the edges are carried by the shoulders 24, again with intermediate isolating elements such as strips 23.

Moreover, such crawling space can be provided between all floors in a multi storey building, wherein access is provided from the living accommodation above the space, even at the elevated stories.
  • Elements 1, 1A can be made from any suitable material. Preferably they are moulded in a substantially closed mould, for integrally forming slabs and beams. In another embodiment one or more of the beams can be provided by mounting them on or to the slab and/or by providing them as inserts in a mould, to be moulded into the elements. These beams can then also be made partly or entirely of a different material, for example metal. Moreover, such beams could be made hollow. Cross beams are preferably at least provided at one, more preferable at least at both opposite ends of an element. The openings 9 are shown as substantially flush with an upper surface of the slab.
