Definitions

  • the present invention relates to an elevated floor assembly.
  • Elevated floor assemblies are commonly used in commercial and office buildings, where substantial numbers of cables, pipes and ducts are required and where it is desirable to maintain accessibility to the latter for ease of installation, change or removal.
  • An elevated floor assembly basically consists of floor panels supported above the base floor by pedestals. The pedestals are normally located so as to provide support at panel corners. Cables, pipes or even air conditioning services are thus installed in a chamber formed between the base floor and the elevated floor and are easily accessible by removing floor panels where needed.
  • Elevated floor assemblies have adjacent floor panels firmly in contact with each other. Supporting the floor panels by pedestals at panel corners allows for some relative movement of the floor panels due to the placement and removal of weight onto the floor panels. This relative movement results in floor squeaking, which can be rather disturbing. Indeed, it is a common experience to walk across such an elevated floor assembly and hear a floor squeak in response to placement and removal of weight of a person crossing the floor.
  • the pedestals can be supplemented by horizontal stringer members.
  • stringer members form a grid to provide support along the panel sides. Due to the extra material, elevated floor assemblies with such stringer members are more expensive and take longer to assemble. Furthermore, the squeak reduction is insufficient.
  • DE 28 56 367 discloses a floor panel assembly for a flat roof. These floor panels comprise slots in their side faces so as to form relatively large openings between adjacent floor panels for allowing water to flow from the upper surface of the floor panel assembly into the plenum created between the base floor and the floor panels.
  • EP 0 411 568 discloses a floor panel assembly having triangular; rectangular and square floor panels. The rectangular floor panels have slots in their hypotenuses to create relatively large openings for allowing to adjust the volume of air blowing through, to check the wirings below and to reduce weigh of the plate.
  • the square floor panel comprises relatively large cutoff portions at its four sides to facilitate removal of the plate.
  • FR 1 547 666 discloses a floor panel assembly wherein the lower surface comprises a chamfered contact surface for resting on a correspondingly shaped support element.
  • the invention proposes an elevated floor assembly comprising floor panels having a thickness, an upper surface, an opposite lower surface and side faces. These side faces have two corner portions and a central portion lying in-between the two corner portions.
  • the elevated floor assembly further includes pedestals, which provide support at the corner portions.
  • two adjacent side faces of two adjacent floor panels are designed so that their corner portions are in abutment, whereas a slot extending over the whole thickness of the two adjacent floor panels is formed, separating the central portions of the two adjacent side faces over at least part of the length of the respective central portions.
  • This thin slot ensures the avoidance of floor squeaking, which is caused by the relative movement between adjacent floor panels in response for example to a load application and removal when a person walks from one panel to the adjacent panel of an elevated floor assembly, or, in fact, any other object moving across adjacent panels. It will be appreciated that the present invention proposes a very simple and inexpensive contribution to provide an elevated floor assembly, which does not give rise to such floor squeaking.
  • Two adjacent side faces of two adjacent floor panels are chamfered so that the slot widens in the direction of the lower surfaces of the two adjacent floor panels.
  • a longitudinal cut is extended over at least part of the length of the central portions of the two adjacent side faces, whereby only that part of the thickness of the panel is removed that has contact with the adjacent panel. Except where the edging is of vertical type, i.e. where the side faces of the floor panels are not chamfered, it will not be necessary for the slot to be cut through the full thickness of the panel. Preferably, however, the longitudinal cut extends over the whole length of the respective central portions, thereby warranting that two adjacent floor panels touch only at their corner portions.
  • the width of the longitudinal cut is preferably in the range of a few tenths of 1 mm. This is sufficient to avoid floor squeaking, while at the same time not allowing too much dirt to accumulate in the longitudinal cuts.
  • the floor panels have a rectangular shape. It is however not excluded to provide the elevated floor assembly with floor panels having any other polygonal shape.
  • FIG. 1 An elevated floor assembly 10 in accordance with the present invention is shown in FIG. 1 .
  • Such an elevated floor assembly 10 consists of individual floor panels 12 1 , 12 2 supported above a base floor by means of pedestals (not shown) so as to define a chamber therebetween in which cables, pipes or even air conditioning services may be installed.
  • the floor panels 12 1 , 12 2 shown in FIG.1 are of rectangular shape and have an upper surface 14, an opposite lower surface 16 and side faces 18, the latter comprising two corner portions 20 and a central portion 22 lying therebetween.
  • Panel supporting heads of the pedestals which are schematically indicated by circles 24, are designed to provide support to the floor panels 12 1 , 12 2 at their corner portions 20.
  • Elevated floor assemblies 10 commonly have adjacent floor panels 12 firmly in contact with each other. Supporting the floor panels 12 by means of pedestals at their corner portions 20 allows for some relative movement of the central portions 22 of the floor panels 12 due to the placement and removal of weight onto these central portions 22. This relative movement results in floor squeaking, which can be rather disturbing and needs to be avoided.
  • this floor squeaking is avoided in that only the corner portions 20 of two adjacent panels 12 1 , 12 2 are in abutment, whereas a slot 26 separates the central portions 22 of the two adjacent side faces 18 1 , 18 2 .
  • the two adjacent floor panels 12 1 , 12 2 have chamfered side faces 18 1 , 18 2 and comprise a longitudinal cut 28 on their upper surface, extending over the whole length of the central portions 22.
  • the chamfered adjacent side faces 18 1 , 18 2 and the two adjacent longitudinal cuts 28 co-operate to define the slot 26, which separates the central portions 22 of the two adjacent floor panels 12 1 , 12 2 .
  • the adjacent side faces 18 1 , 18 2 are only in abutment at their corner portions 20, between which relative movement is excluded due to the secure support provided by the panel supporting heads 24 of the pedestals. It follows that although some relative movement remains between the central portions 22 of the panel side faces 18 1 , 18 2 , the slot 26 separating the latter avoids floor squeaking in the elevated floor assembly 10.
  • each side face 18 of each floor panel 12 of the elevated floor assembly 10 comprises a longitudinal cut 28 in its central portion 22.
  • the cut 28 has a width in the range of 1 to 2 mm, which is sufficient to avoid floor squeaking, while at the same time not allowing too much dirt to accumulate in the latter.
  • a floor panel 12 is commonly a panel of 60 cm ⁇ 60 cm, both FIG.1 and 2 are not to scale, particularly with regard to the width of the longitudinal cuts 28, which is greatly exaggerated.
  • the chamfering of the panel side faces 18 is advantageously of about 1° to 2° and is also exaggerated in FIG. 2 .
  • a floor panel 12 for an elevated floor assembly 10 commonly a rectangular shape, i.e. four panel sides 18. However it is not excluded and still within the scope of the present invention to design the elevated floor assembly 10 with floor panels 12 having any other polygonal shape.
