Definitions

  • the invention relates to a floor covering for industrial halls, in particular for large-area warehouses, which can be placed on a preformed substrate, preferably made of concrete.
  • the invention is therefore based on the object of creating a floor covering for industrial halls which, on the one hand, is highly resilient through vehicles, machines and stored goods and, on the other hand, ensures reliable protection against unwanted escape of environmentally hazardous liquids into the underground.
  • the double-walled covering element according to the invention contains a gap space filled with a dimensionally stable but nevertheless air-permeable spacer material, which can be closed airtight and connected to a leak monitoring device.
  • the top and bottom plate of the covering element can consist of low and high-alloy steel or of other chemical-resistant alloys and compounds, such as tombac or - with a correspondingly low load - also of welded plastic sheets.
  • a metal grid, in particular expanded metal, is particularly suitable as a dimensionally stable spacer material that should be resilient to pressure but still permeable to air.
  • the latter is a stamped sheet, in which both openings are punched in the course of the stamping process and metal bends are carried out. The result is a mesh-like, three-dimensional structure with high pressure resistance.
  • the covering plates are advantageously fastened by means of steel straps, which are either doweled to the base or embedded in the base during manufacture of the concrete base.
  • the bottom plate of the covering elements is welded onto the retaining band either point by point or with a continuous weld seam. If two adjacent sub-plates are butt welded together, they can be welded to the strap at the same time. A further possibility is that first the one lower plate is welded onto the holding band and then the other is welded overlapping.
  • the sub-plates are expediently fastened to the tether using the so-called island method; short strips are welded at intervals and alternately in order to minimize thermal expansion and tension.
  • additional retaining straps can be arranged under the base plate, which are welded to the base plate by means of bores.
  • a vapor barrier layer for example in the form of tar-tipped insulation cardboard, is expediently placed between the base and the base plate.
  • the lower plate is loosely covered with the expanded metal sheet.
  • the top plate is then placed on the expanded metal sheet and preferably with the bottom plate in the pilgrimage step process tightly welded.
  • several covering elements are used, the gap spaces of which are vacuum-separated from one another and can be connected to one another by lines for the purpose of leak monitoring and leak detection.
  • U-shaped pipe sections are expediently used, which can be connected to adjacent connecting pieces of two covering elements.
  • a slight inclination is expediently provided in the floor covering, which ends in a sump from which any outflowing liquids can be better pumped out.
  • the sump can also be lined with the vacuum-monitored double jacket.
  • Pits e.g. Work pits in industrial plants, or channels, for example for receiving train tracks, are provided, which are also lined with the leak-monitored double wall.
  • the pits or channels form a collecting area for escaping chemical liquids and are dimensioned such that, for example, the contents of a tank car to be unloaded there can be collected.
  • Bolts or nuts can be welded to the top plate to fasten machines and devices to the floor covering.
  • mounting plates are welded on, which in turn can carry mounting bolts or nuts. It is important that the double-walled floor covering is not drilled through during assembly.
  • the double-walled flooring can be prefabricated element by element.
  • elements that are open on one side are expediently prefabricated, which are welded closed with an overlap plate or a cover strip.
  • individual channel or pit areas can also be prefabricated and then assembled.
  • the edges of the covering elements adjacent to the wall can be bent upwards by 90 ° and fastened to the wall using suitable angle pieces.
  • the gap spaces of the floor covering can be evacuated via a suction connection and connected to a manometer of the leak monitoring device via a measuring line.
  • the suction line is expediently connected near the lowest point and the measuring line near the highest point of the gap area.
  • a liquid barrier can be arranged in the suction line, which ensures that any suctioned liquid cannot reach the monitoring device.
  • detonation protection devices can be arranged in the suction line and / or the measuring line, which prevent a flame from passing from one area to the other.
  • a closable filling and / or test nozzle for filling in test gas and / or for testing the entire system can be arranged at a point in the gap space remote from the measuring line connection.
  • the gap can, for example, be charged with an inert gas, such as nitrogen, for leak control via this nozzle, or can be flooded therewith prior to evacuation for the purpose of reducing corrosion.
  • the gap spaces of individual covering elements can be separately connected to the leak monitoring device and their tightness can be checked for leak detection.
  • the same result can be achieved if the gap spaces of the individual covering elements are uncoupled one after the other and the subspaces formed in this way are connected to the leak monitoring device and their tightness is checked. In this way, the leak or the leak area can be located relatively quickly even in large industrial halls.
  • the elements 11 of a floor covering shown in the drawing essentially consist of an upper plate 1 and a lower plate 2, between which a spacer layer 3 is arranged.
  • the top and bottom plates 1, 2 are expediently made of a thick-walled steel sheet, while the spacer layer 3 consists of expanded metal.
  • the expanded metal 3 has a mesh-like, three-dimensional structure with a high transverse load capacity. Due to breakthroughs and metal bending, the expanded metal 3 is permeable to air, so that between the two plates 1 and 2 a coherent gap space 8 is formed, which can either be evacuated or filled with gas.
  • the floor covering can be welded with its lower plate 2 to steel straps 4, which in turn can be fastened to the preformed concrete base 5 by means of screws 6, 7.
  • the evacuable gap space 8 can be connected to a leak monitoring device 17 via a measuring line 16.
  • FIG. 2 it can be seen how two adjacent covering elements 11 of the floor covering are connected to one another at their joints and fastened to the substrate 5.
  • the fastening screws 6, 7 penetrate the retaining band 4 off-center, either offset or parallel. This leaves a central path that is not damaged by screw holes that could later give rise to leaks.
  • the lower plates 2 of the two covering elements 11 are butt welded together and welded to the holding band 4 with the same weld seam.
  • the expanded metal sheets 3 are placed on the sub-plates 2 fastened to the base 5 in this way.
  • the top plate 11 shown on the left in FIG. 2 is first placed thereon and tightly welded at its edge with a continuous weld seam 14 to the bottom plate 2 underneath.
  • the expanded metal sheet 3 in question is also welded on.
  • a plurality of covering elements 11 are connected to one another at joints 20.
  • the covering elements 11 are double-walled in the manner described above and enclose a spacer layer 3 made of expanded metal and a gap space 8 between their top and bottom plates 1, 2.
  • the gap spaces 8 are connected to one another at the connecting pieces by means of U-shaped pipe pieces 12.
  • One of the covering elements contains a depression designed as a pump sump 23, the walls 24 and bottom 25 of which are also double-walled and have an evacuable gap space 8.
  • the edges of the fitting elements are bent upwards by 90 ° and in this way form a tub edge 26 of, for example, 10 to 40 cm high.
  • the upper edge 28 of the tub rim 26 is overlapped by a drain plate 29 fastened to the side wall 27, so that a liquid flowing down the wall does not get into the space 30 between the covering and the wall but onto the monitored floor covering.
  • a tar-coated insulation cardboard 40 prevents vapor diffusion from taking place in the floor covering 5.
  • the gap space 8 of the floor covering is connected via a suction line 31 and a measuring line 16 to a leak monitoring device 17 containing a vacuum measuring device 32.
  • the suction line connection 33 is in the vicinity of the lowest point of the floor covering, while the measuring line 16 is connected to the highest point 34 of the gap space 8.
  • a liquid barrier 35 In the suction line 31 there is a liquid barrier 35, with which liquid is avoided in the event of a leak.
  • 16 are located in the suction line 31 as well as in the measuring line 16 detonation protection devices 36 which prevent a flame from passing from one area to the other in the event of a fire.
  • a filler and test nozzle 37 is arranged on the upturned tub edge 26 of the floor covering, which can be closed by means of a ball valve 38 and which can be acted upon by an inert gas, for example nitrogen, for leakage control of the entire covering.
  • an inert gas for example nitrogen
  • bolts 41 or nuts can be welded onto the top plate 1.
  • mounting plates 42 which in turn carry mounting bolts 43 or nuts.
  • the top plate 1 can also be designed as a sandwich plate, which is provided with a plastic pad 44. This plastic layer can be spread, welded, glued or poured on. Furthermore, an industrial floor 44, a synthetic resin coating or a paint can be applied to the floor.
  • the industrial floor can be made, for example, on a cement or synthetic resin cement basis.
  • the coating should in particular be chemically inactive and should prevent the formation of sparks, as can occur, for example, when driving with forklifts when grinding the forks on a metal surface or when handling steel sheet containers due to friction on a metal surface.
  • the floor covering described is used in particular in industrial and storage halls, in which explosion protection must also be ensured.
