Definitions

  • the invention relates to a grid rod for raised floors, consisting of footrests, which have head plates for connecting the grid rods made of square tubes, as well as floor plates laid on the grid rods, the head plates of the footrests on their circumference with cross-shaped pairs of slots and holes for Inclusion of the grid rod ends or of tabs, spikes or fastening screws on the grid rod ends are provided (Siche DE-U-8 701 635).
  • the head plates of the footrests have pairs of cross-shaped slots on their circumference, into which the side walls at the ends of each grid rod are inserted from above.
  • One of the two other walls of the grid rod is provided with corresponding recesses at its ends in order to enable the ends of the side walls of the grid rod to be inserted into the slots in the head plates of the footrests.
  • tabs projecting inward are provided in one bar type and, in another bar type, bores are arranged instead of these tabs for the passage of fastening screws.
  • the grid bars with the tabs at their ends are inserted practically loosely into the supporting substructure, while the other Grid type is screwed to the head plates of the footrests.
  • the load-bearing substructure is reinforced even better.
  • the two stiffening variants for the load-bearing substructure of the raised floor have so far disadvantageously required the production and storage of two different types of grid bars.
  • the above-mentioned recesses in the locking bars create sharp edges, which form a risk of injury to the fitters during assembly of the raised floor and subsequent installation work.
  • the invention has for its object to eliminate the above shortcomings and to create a grid rod for raised floors, which can either be inserted loosely into the supporting substructure of the raised floors or can also be screwed tightly thereto.
  • Such a grid bar can advantageously, depending on its selected installation version, be loosely inserted into the load-bearing substructure or also firmly with it be screwed.
  • the same type of grid bar can therefore be used for both installation variants, which simplifies the manufacture and storage of these bars. If it turns out after installation of the grid bars that the raised floor or its supporting substructure z. B. must be stiffened to a greater extent in sections, you only need to simply turn the grid rods in the relevant floor section and screw them to the top plates of the footrests. The exchange action of grid bars that was previously required in such situations is no longer necessary. Yet another advantage of the grid rod according to the invention is that it has no sharp-edged ends that could pose a risk of injury.
  • the optional arrangement of the grid rod in one or the other installation position in the load-bearing substructure of the raised floor is made possible in that the slanted side walls of the grid rod can be inserted into the slots on the head plates of the previously mounted footrests in each installation position. Either the tabs, mandrels or the like are brought into engagement with the holes in the head plates of the footrests or the fastening screws passed through the holes in the rod ends are screwed into the holes in the head plates. Self-tapping screws are used for this purpose.
  • the ends of the side walls of the grid bar are beveled at an angle of approximately 60 ° with respect to the other two bar walls.
  • Yet another embodiment of the invention is characterized in that on the other two each other opposite walls as the side walls of the grid height compensation layers z.
  • plastic or cork strips are provided to compensate for washers on the top plates of the footrests. This achieves the required full support of the floor slabs over practically the entire length of the grid bars.
  • the grid bars are thereby also fixed in the "loosely inserted state”.
  • the washers usually made of plastic, serve in a known manner as fixing aids for the base plates and for sound insulation.
  • the raised floor partially shown in Fig. 1 settles together from height-adjustable footrests (10), grid bars (11) and square base plates (12).
  • the footrests (10) are attached to the unfinished floor (13) of the building space concerned at the beginning of the assembly of the raised floor.
  • Each footrest (10) carries a head plate (14), on the circumference of which cross-shaped pairs of slots (15) are worked out, which are open to the outside.
  • a bore (16) is provided in the middle between two slots (15).
  • the footrests (10) together with the grid bars (11) form the load-bearing substructure for the floor panels (12), which are supported on the grid bars (11).
  • the grid bars (11) are of identical design and one of them will now be described in detail below with reference to FIGS. 2 and 3.
  • the grid rod (11) is made from a square tube and its two side walls (17) have bevelled ends (18) parallel to one another. Viewed from the side, therefore, the grid bar (11) has the shape of a parallelogram (Fig. 2).
  • the angle of inclination of the ends (18) of the side walls (17) relative to the other two rod walls (19 and 20) is z. B. 60 °.
  • Elongated holes (21) for the passage of fastening screws (27) are worked out at the opposite ends of the wall (19) of the grid rod (11) according to FIGS. 2 and 3.
  • tabs (22) are punched out and bent inwards at a right angle.
  • height compensation layers (23) On the outer sides of these walls (19 and 20) of the grid rod (11) are height compensation layers (23), for. B. strips of plastic or cork attached, the purpose of which is explained.
  • the grid bars (11) can be connected to the footrests (10) either with their wall (19) or (20) pointing upwards.
  • the beveled ends (18) of the side walls (17) of the grid rod (11) are inserted laterally and from above into the corresponding pairs of slots (15) on two opposite footrests (10), as shown in Fig. 1 by the Arrows is indicated. 4, the tabs 22 are brought into engagement with the bores (16) between the corresponding pairs of slots (15).
  • the grid rods (11) are loosely connected to the head plates (14) of the footrests (10).
  • the wall (19) is at the top and the elongated holes (21) overlap the corresponding bores (16) between the footrests (10) adjacent to the pairs of slots (15).
  • the grid rod (11) is connected to the head plates (14) of the adjacent footrests (10) by means of fastening screws (27) which pass through the elongated holes (21) and into the bores (16) in the head plates (14) can be turned. Self-tapping fastening screws (22) are used for this.
  • washers (24) are arranged on the head plates (14) of the footrests (10), which contain cross-shaped recesses (25) to expose the pairs of slots (15) upwards, so that the grid rods (11), such as described above, be connected to the head plates (14) can.
  • the washers (24) carry four symmetrically arranged stops (26) on their upper side, which form positioning aids when placing the base plates (12).
  • the washers (24) are made of plastic and also have a sound-absorbing effect.
  • the material thickness of the washers (24) corresponds to the wall thickness of the grid bars (11) plus one of the height compensation layers (23). This ensures that the base plates (12) rest on practically the entire length of the grid bars (11).
  • mandrels for example in the form of welded bolts, can also be provided.
