Description

Title

Liquid-tight floor facility with connectable floor panels with an integrated liquid collection and drainage system and such a floor panel.

Technical area

The present invention relates to a liquid-tight floor or floor facility, more in particular, the invention relates to a liquid-tight floor or floor facility comprising connectable floor panels, with an integrated liquid collection and drainage system, and such a floor panel.

BACKGROUND OF THE INVENTION

A liquid-tight floor or floor facility is generally used where it must be prevented that certain activities, including human actions, soil-threatening substances and liquids can get into the soil or subsoil.

Current national and international legislation in the field of Environmental Management and Soil Protection, for example, binds business activities with a risk of soil contamination to regulations for collection facilities, waste water treatment and other protective and preventive measures.

In order to prevent contamination of ground and groundwater by contaminations of, for example, fuels, oils, coolants, hydrocarbons or other chemical or oxidizing substances, liquids, alkalis and acids and washing water, these national and international regulations, provisions and measures must be taken in order to realize a negligible risk of leaking to the bottom. Examples of this are the installation of liquid-tight floor facilities at locations where there is a high or increased risk of spillage, leakage, calamities and the like as a result of which dangerous situations and soil contamination can arise.

Examples include fuel intake or fuel delivery points, fuel distribution points, washing places for objects and / or vehicles, storage and transfer places for (bulk) liquids, storage and loading of bulk and general cargo, distribution depots, storage and transfer places for chemical substances, industrial production areas, or areas for process activities and operations for the collection, treatment and discharge of waste water or process water, airports, agricultural industry such as stable construction and the like.

In addition to the specific requirements that such liquid-tight floor facilities must meet and other relevant environmental measures, it is of course also necessary to have a liquid-tight drainage system, sludge collection and separating system for liquids and other substances such as clay, sludge and other substances collected with such a floor provision. dirt that is carried along with the liquids, among other things.

Various forms of liquid-tight floor or floor facilities are common and known. The known facilities are often implemented in construction. The materials used often concern elements of reinforced or unreinforced concrete; reinforced or unreinforced concrete poured on site; bituminous bonded materials such as asphalt or ceramic systems, metal systems or combinations thereof. Most liquid-tight floor facilities are also not moved during their life expectancy. In recent years, geomembrane collection systems in the form of product-resistant film systems or a liquid-tight sand-bentonite polymer gel layer have also been used, for example as a liquid-tight substrate for an industrial location, (waste) water basin, parking facility or landfill and the like.

Additional facilities such as waste water drainage systems from, for example, industrial sewers, gutters, gullies, sludge collection pits and separators are also among the usual necessary liquid-tight collection, drainage and treatment facilities. These collection and discharge systems are connected to a liquid-tight floor facility or the (liquid) dust collection system thereof.

Both the individual and the relationship between a durable resistance to dynamic and static mechanical loads and thermal and chemical resistance of the conventional and known liquid-tight floor and floor facilities is limited. This limitation can, among other things, be expressed in cracks, crumbling, subsidence, creep, detachment, deformation and dissolution of the materials used by attacking the collected (liquid) substance (s) or the forces of ascending and overcoming vehicles or of forces exerted thereon. installed installations.

An architectural liquid-tight floor provision aims to be both liquid-tight and to remain in use during use, as well as to be the bearer of installations but also of on-and-off traffic in the form of (often heavy) static and dynamic wheel loads, point loads or wheel load repetitions. . The robustness of structural liquid-tight floor facilities is therefore often not an optimal combination of the function of carrier of dynamic and static axle and point loads and the function of liquid-tightness.

Many common liquid-tight floor or floor facilities are also limited or selectively resistant to short-term or sustainable influences of the chemical, oxidising substances, alkalis or acids and other (liquid) dust loads that the system must absorb. For example, metal can corrode or be subject to metal fatigue and thus lose its properties. For example, concrete cannot tolerate acids very badly due to the lime component present without being affected.

Concrete is also strong on pressure but not on draft, so that special reinforcement must compensate for this. Occurring cracking then again violates the requirement of liquid tightness. For certain heavy loads, a concrete structure must therefore be very heavily dimensioned.

For example, bituminous structures are less resistant to oil-containing products. In addition, certain thermal loads such as alternating heat and cold, but also UV influences, limit usage. Fatigue and weathering of the materials also limit the service life. Certain point loads in concrete facilities often lead to crumbling, whereby the liquid density is directly at stake. With asphalt, point loads at a certain temperature lead to irreversible deformation.

Non-structural liquid-tight soil collection facilities such as drip trays or rack basins are less suitable for large static or dynamic (wheel) loads, as a result of which the function is often limited to a liquid-tight collection facility, suitable for a certain group or type of substances and with limitations on durability. To make the limitation of sustainability as small as possible, liquid-tight collection facilities with a specific specific resistance to the substances to be collected are manufactured and used under certain usage restrictions. This includes UV resistance or thermal loads (heat and / or cold influences) and corrosion resistance such as galvanizing and resistance to dynamic and static loads.

Moreover, with the exception of certain architectural elements, the relocation of traditional facilities is accompanied by deformation whereby the entire liquid-tight and additional collection facility with pipework must be considered as lost.

Dutch patent NL 1040025 discloses a movable liquid-tight floor or floor facility made of adjacent, connectable floor elements made of plastic, consisting of a roadway with an integrated liquid-collecting facility.

US patent application US 2005/0204662 describes a system of elongate floor plates made of one piece and of plastic, in particular polyvinyl chloride (PVC), with a top surface or top surface in which a system of parallel discharge channels is formed for longitudinally (axially) from a floor plate, over its surface, draining liquid collected by the floor plate to a liquid collection facility located on one or both end sides adjacent to and outside the floor plate into which each of the discharge channels ends.

These floor plates can be joined adjacent in the transverse direction, the cooperating coupling means of adjacent floor plates forming a composite discharge channel in the longitudinal direction (axially) of the coupled floor plates for draining off liquid (coupling gap) formed between the adjacent floor plates from the upper surface. For reasons of weight saving, the floor plate is formed as an open structure, with a number of hollow chambers extending longitudinally of the floor plate below the upper surface.

From International Patent Application WO 00/62603 a matting of elongated matting modules is known which, viewed in transverse direction, can be placed adjacent to their longitudinal edges. In and distributed over the surface to be loaded, each mat module is provided with openings which open out or connect to discharge channels extending longitudinally below the surface to be loaded from a mat module. The relevant drainage channels connect to liquid collection facilities placed on the ends next to and outside of a mat module,

The floor plates or floor panels, or the matting, known from US 2005/0204662 as WO 00/62603, do not offer an integrated solution for draining liquids from coupled floor panels. As a result, these known floor plates or floor panels or the matting are unsuitable for installing a liquid-tight floor facility with length and width dimensions which are a multiple of that of a single floor element, floor plate or mat module, without having to intervene with structural measures. Furthermore, the constructions described are by no means suitable for constructing a liquid-tight floor facility as a support for installations, but also for on-and-off traffic in, inter alia, the form of (often heavy) static and dynamic wheel loads, point loads or wheel load repetitions.

Although the liquid-tight floor or floor facility known from NL 1042005 is suitable for the rapid and flexible installation of a liquid-tight floor facility with an integrated drain system and with length and width dimensions that are a multiple of that of a single floor element, the use is herein of grate or bridge plates described for covering overflow drains of coupled floor elements on the loaded or to be loaded surface.

Summary of the invention

An important object of the present invention is to realize a liquid-tight floor or floor facility without the described drawbacks which occur with fixed structural liquid-tight floor or floor facilities and the construction of which is suitable for the production of a versatile applicable liquid-tight floor facility as a support for installations but in particular also for on-road and over-driving traffic in the form of (often heavy) static and dynamic wheel loads, point loads or wheel load repetitions.

More specifically, this means that the present invention, in use, continues to satisfy as much as possible both individual and combinations of standards and requirements in the field of dynamic, static, mechanical, thermal and chemical resistance combined with flexibility in the dimensions of the desired liquid-tight floor covering. or ground supply and which, moreover, can be installed quickly and without major structural provisions and can, if necessary, be removed easily and quickly.

To this end, the present invention provides a liquid-tight floor facility, comprising adjacent connectable, rectangular floor panels with first and second opposite peripheral edges and third and fourth opposite peripheral edges, wherein each floor panel has a closed surface to be loaded for use, an unloaded surface for placement on a substrate and a comprises liquid collecting and discharge system accessible from the surface to be loaded for liquids, characterized in that each floor panel is provided with a first liquid collecting channel extending along the first peripheral edge and arranged in the floor panel and open on the surface to be loaded, the flange or lip extending parallel to the surface to be loaded, with a nose-like body pointing in the direction away from the surface to be loaded, such that with adjacent floor panels the nose-like body of one floor panel fits one end engages in the first liquid collection channel of the other floor panel, and a liquid discharge channel extending along the third peripheral edge and arranged in the floor panel, on the surface to be loaded, the first liquid collection channel terminating in the liquid discharge channel and being closed at the fourth peripheral edge, and the surface to be loaded being recessed at least with respect to the first, second and fourth peripheral edge.

In this movable liquid-tight floor facility, the mechanical functions for connecting floor panels adjacent to each other and the functions of liquid-tightness and liquid collection and discharge are fully integrated. Because of the nose and gutter coupling, the floor panels are excellent for easily and quickly building a liquid-tight floor facility of relatively small to relatively large dimensions, without the need for the use of grate or bridge plates or external liquid drainage channels when connecting linkable floor panels for the manufacture of a liquid-tight floor or floor facility.

The term liquid-tight as used and intended in the present description and claims and as also defined and understood in the current national and international legislation in the field of environmental management and soil protection, means that no liquid of the surface to be loaded of the liquid-tight floor or floor ground supply, that is to say the surface used for (business) activities, may reach the unloaded surface of the liquid-tight floor or ground supply, that is to say the surface of the floor or ground supply resting on a surface. Due to the integration of the mechanical coupling functions and the liquid collection and discharge system in the floor panel itself, the liquid collection and discharge system in the sense of the above definition is per se also liquid-tight.

Such a liquid-tight floor or floor provision of, for example, wood, a multiplex material or a fiber-reinforced plastic composite in the form of a sandwich construction with a plastic skin enclosing on all sides, such as a multi-layer resin-bonded glass fiber skin, is about a factor 3-5 or more lighter than a concrete or asphalt facility of the same size. Due to the nature and composition of the floor panels, the permitted axle loads or point loads for this are, compared to traditional liquid-tight facilities of concrete or asphalt, an equivalent factor of approx. 8 more favorable. In practice, floor panels with a length of 5 meters or more and a width of 2 meters or more can be manufactured in this way, which are relatively easy to handle and, for example, to transport by road, i.e. without the need for use. of exceptionally heavy equipment or means of transport. Panels of smaller dimensions can of course also be produced.

With the invention, a liquid-tight floor or floor provision can thus be manufactured without grid or bridge plates transverse to the direction of travel of vehicles across the surface to be loaded on two or more coupled floor panels, which direction of travel can be arranged transversely of the first and second peripheral edges. With an equal axle, point or liquid load, the service life expectancy of the liquid-tight floor or floor provision according to the invention is therefore distinctively more favorable than with the already known connectable floor elements. The construction according to the invention is particularly suitable for supporting axle loads of approximately 20 tonnes or higher or equivalent traffic class 600.

A method is hereby allowed for cleaning, washing and refueling of (electric) vehicles and draining and filling of installations on or above this floor facility, the collection and removal of chemical (liquids) substances and the collection, separation and separation in and near this collection facility. treatment of soil-polluting (liquids) substances and waste water. The provision can easily be made electrically insulating by the use of panels of plastic or wood material.

In this description and the claims, the term liquid collection and discharge refers not only to the collection and discharge of liquids, but also to other substances, whether soil-contaminating or not, such as clay, sludge or other dirt that is inter alia mixed with the liquid (s). carried away.

In an embodiment of the floor provision according to the invention, each floor panel is provided with a second liquid collecting gutter extending along the fourth circumferential edge and arranged in the floor panel, said second liquid collecting gutter opening into the first liquid collecting gutter and closed at the second circumferential edge is.

In order to allow as much liquid as possible to flow away from the surface to be loaded from a floor panel to the liquid discharge channel, the invention provides that the surface to be loaded is cascaded, viewed from the fourth peripheral edge to the third peripheral edge. That is, the deepened location of the surface to be loaded increases in the direction of the third peripheral edge where the liquid discharge channel is located. In practice, a floor panel has been realized with three levels. The deepened location can of course also be continuous or step-by-step.

In yet a further embodiment of the invention it is provided that at least the first, second and fourth peripheral edge of a floor panel are provided with an integrated edge or sill of the same height, measured relative to the surface to be loaded, measured from the unloaded surface of the floor panel . This also improves the conduction of liquid discharge over the surface to be loaded to the liquid discharge channel and it is prevented that the liquid collection troughs have to be too wide and / or too deep to prevent flooding thereof, which would also have repercussions on the thickness of a floor panel and thus the weight of a floor panel.

For reasons of force action, in particular in the case of vehicles traveling over the surface to be loaded by coupled floor panels, the invention provides in an embodiment that the raised edge or sill adopts obliquely, at an obtuse angle, to the surface of the floor panel to be loaded. For example, a blunt angle measured from the surface to be loaded of 120 degrees or more.

Also, in order to prevent unnecessary force action on coupled adjacent floor panels as much as possible and also from an aesthetic point of view, the invention preferably provides that the thickness of the flange or lip and the nose-shaped body at the second peripheral edge and the depth of the first liquid collection trough and height of the first peripheral edge delimiting this liquid collecting trough are of such dimensions that floor panels coupled to their respective first and second peripheral edges are flush with each other.

In the case of adjacent floor panels which are also provided with a second liquid collection trough at the fourth peripheral edge, the invention further provides that the depth of this second liquid collection trough and height of the fourth peripheral edge delimiting this second liquid collection trough are such that at their floor panels coupled to the fourth circumferential edge in question, with the aid of a coupling plate engaging in the relevant second liquid collection troughs, engaging from the surface to be loaded surface.

In one embodiment, the floor panel is provided at its third peripheral edge with a higher raised edge or threshold, which defines the liquid discharge channel and forms a stop for a screen wall to be applied to the surface of the floor panel to be loaded.

For floor panels where the dimensions of a floor panel have a length to width ratio of approx. 2: 1, for example with a length of approx. 5 -6 meters and a width of approx. 2 - 3 meters and where the first and second peripheral edges are at the are located on the long side and the third and fourth peripheral edges are on the short side, the use of a coupling plate on the coupled fourth peripheral edges is not disadvantageous because these coupling plates do not lie transversely to the direction of travel of vehicles over the surface of the coupled floor panels to be loaded. because the direction of travel across the floor provision will in practice be transverse to the first and second peripheral edges.

Another object of the invention is to connect the floor panels of the floor provision, intrinsically liquid-tight to each other and to a single central drainage system, while maintaining all functions. A distinctive feature here is that each floor panel has at least one integrated liquid collection and discharge system for collecting liquids and other substances as mentioned from the surface to be loaded, wherein the liquid discharge system is located on the third peripheral edge of each floor panel and forms it with coupled floor panels of a contiguous liquid discharge system, in an embodiment of the floor provision according to the invention, the liquid discharge channel ends at each end thereof in a tubular or semi-tubular outflow or inflow opening.

For easy coupling of the tubular or semi-tubular outflow or inflow openings of coupled floor panels, the invention further provides that the outflow or inflow opening at the first peripheral edge of the floor panel does not project out beyond the first peripheral edge and at the second peripheral edge on such a distance from the nose-shaped body ends that with floor panels coupled to their respective first and second peripheral edge the respective outflow openings and inflow openings connect to each other.

The connecting outflow or inflow openings can be connected to each other simply and effectively in a liquid-tight manner by means of a sleeve or sleeve engaging over the connection. Of course, other closing means can be used for the mutually engaging outflow openings and inflow openings of coupled floor panels, for instance by providing the relevant outflow or inflow openings of different dimensions so that they can engage with each other.

In another embodiment, the invention provides a liquid discharge channel with outflow openings that open out into the third peripheral edge, in particular in two outflow openings located at the first and second peripheral edge, for connection to a liquid discharge system located outside the floor panels.

The floor arrangement according to the invention is, in addition to the interlocking nose / liquid collection channel coupling and the coupling by means of a coupling plate as described above, preferably also provided with further mechanical coupling means for coupling floor panels adjacent to each other and / or for connecting to a floor panel linking objects.

In an embodiment the further coupling means comprise coupling elements spaced from and along at least one peripheral edge, fixedly accessible in the floor panel and accessible from the surface to be loaded, such as for example threaded bushes, bayonet connecting bushes and similar coupling bushes, for coupling into these bushes and preferably detachably therewith. of fasteners.

It is hereby possible to further connect adjacent floor panels to each other mechanically by coupling strips which are connected to opposite coupling bushes via screws or otherwise. The coupling sleeves or coupling elements can also be used for fixing uprights of, for example, a roof or the like on a floor panel. The invention further provides an access and removal plate to be connected to the coupling means, which plate preferably extends along a first peripheral edge of a relevant floor panel. The further coupling means are preferably located at a distance from and along the third and fourth peripheral edges of a floor panel, for not mounting objects of vehicles moving over the surface to be loaded, in the direction of travel.

By releasably coupling hoisting eyes to the further coupling means, or coupling elements such as for instance threaded bushes, bayonet connection bushes, floor panels can easily be hoisted and placed in their desired position and of course on and from vehicles for transporting the panels.

In one embodiment, the invention provides approximately S-shaped coupling plates, with an elongated or extended long side or leg engaging the loaded surface of the floor panel and a short side or leg engaging the edge or sill on the third peripheral edge. Such coupling plates are used, among other things, for mounting a screen wall along and on the surface to be loaded on a floor panel or coupled floor panels.

The invention is furthermore based on the task of allowing the floor provision to be integral and distinctive in a sustainable manner to meet the applicable requirements, provisions and standards, including NEN, Euro and CUR standards for dynamic, static, mechanical, thermal and chemical resistance. , while retaining the functions of liquid tightness. A distinction is made here that the composition of each floor panel can comprise a heavy-duty self-supporting structure without a delamination risk as is known from traditional structures.

To this end, the invention provides inter alia for this by manufacturing a one-piece floor panel of a fiber-reinforced plastic composite or a glass-fiber-reinforced plastic or wood laminate including a sandwich of multiplex plate material, with a total thickness of the order of 70 mm.

For a perfect location and collection of unevenness in a surface, the floor provision according to the invention also provides that the floor panels are or are placed on a cushion-filled bottom layer filled with sand.

The invention is also based on the task of being able to connect and disconnect the facility relatively easily, optionally stack and store it in sea containers and move it to any other location and put it back into operation again, while retaining all functions. In a preferred embodiment, each floor panel for this purpose is rectangular in shape, with a length to width ratio of approximately 2: 1. The first and second peripheral edges are then located on the long side and the third and fourth peripheral edges are on the short side.

It is also an object of the present invention to provide an economical improvement over conventional applications through applications of the described durable and lightweight materials. The implicit requirements for foundations of the facility become simpler. In addition, large and structural savings can be achieved in, among other things, transport, processing, maintenance or repair, economic or technical depreciation and this is structurally distinctively more favorable than conventional provisions.

In a further elaboration, the design and composition of the entire liquid collection and discharge system is designed in such a way that installations, utilities and pipework can be placed above, on, in or near the collection system or can be taken up or dismantled again. The design, composition and properties of the entire collection and removal system make it relatively easy to move to any other location.

The structure and choice of materials is such that the original design, composition or dynamic, static, mechanical, thermal and chemical properties of the floor panels and the liquid collection and discharge system do not change under the influence of the collected (liquids) substances. This may include releases of liquids and liquids as a result of cleaning and washing, but also refueling, filling and draining of engine liquids such as engine oil, coolant or windscreen washer fluid or storage and transfer of acids or alkalis and other oxidizing or chemical (liquids) substances .

In a further elaboration, the floor provision with the integrated liquid collection and discharge system is suitable for repeatedly running over or bearing all occurring wheel or axle loads, such as very heavy fixed and mobile loads of company traffic and traffic on public roads, according to traffic class 600.

The invention is based on the insight that business activities with soil-threatening (liquid) substances must take place on or above liquid-tight containment facilities and that it offers economic advantages to realize a movable, lightweight, durable and resistant liquid-tight floor provision that is and remains permanently suitable for installation. of heavy and light objects or can be driven over by heavy or light axle loads.

The invention also provides a floor panel for use in a floor facility as described above. In particular a floor panel comprising a body reinforced with fiberglass cloth constructed according to a sandwich construction and at least over the surface to be loaded and subsequently over the flange or lip and the nose-shaped body and into the liquid collection trough and the liquid discharge channel surrounded by a liquid-tight skin.

For registration and inspection purposes, the invention further provides that each floor panel is provided with its own unique identification, in particular with an RFID tag or other identification that can be read remotely by radio.

In a further aspect the invention provides a method for manufacturing a pressure bed suitable for laying a floor facility with floor panels according to one or more of the preceding claims, comprising the steps of: - spreading a tarpaulin on a surface or paving or cloth made of plastic material, the dimensions of the tarpaulin or cloth being at least twice the dimensions of the floor facility to be manufactured, - applying an adjusting frame to a half of the spread sail or cloth, the dimensions and contour of which correspond to the dimensions and contour of the floor facility to be manufactured and with a frame height at least equal to the height required for compensating for unevenness in the subsurface or paving and for obtaining a desired fall or slope in the floor facility, - applying a pressure bed of sand, granulate within the adjusting frame or preferably a pressure bed of sand mixed with cement, m with a height equal to the frame height, - applying the other half of the sail or cloth over the pressure bed while forming a cushion-shaped bottom layer, and - closing the formed cushion-shaped bottom layer by attaching the sail to the adjusting frame or cloth.

One or more floor panels are then provided on the thus formed, closed cushion-shaped bottom layer, for manufacturing the floor provision as discussed above. The adjusting frame can be made of wood, plastic or metal and the sail or cloth can be attached to the adjusting frame by stapling, screwing or otherwise.

These and other aspects, features and advantages of the present invention will be further elucidated by the following description of embodiments of a movable installation comprising a drivable and resistant lightweight liquid-tight floor provision suitable for placing and carrying heavy and light vehicles or axle loads, bearing and fixing. cleaning, washing and refueling of vehicles and draining and filling of installations and for the collection, separation and treatment of soil-polluting substances and wastewater in and near this floor facility and for the collection or above this collection facility.

Detailed description

Figure 1 shows a schematic, perspective view of a rectangular floor panel 1 according to the principle of the invention and illustrates an embodiment of the present invention.

The floor panel 1 comprises a surface 2 to be loaded, i.e. the surface on which activities take place as discussed above, and an unloaded surface 3 with which the floor element 1 rests on a surface (not shown).

The panel 1 is bounded by first 4 and second 5 opposite peripheral edges and third 6 and fourth 7 opposite peripheral edges. In the embodiment shown, the first and second peripheral edges 4, 5 lie along the long sides of the rectangular floor panel 1 and the third and fourth peripheral edges 6, 7 lie along the short sides of the floor panel 1.

The floor panel 1 is provided with a first liquid collection trough 8 extending along the first peripheral edge 4 and arranged in the floor panel 1, which channel is open on the surface 2 to be loaded for collecting liquid from the surface to be loaded 2. Along the second peripheral edge 5 a flange or lip 9 extends parallel to the surface 2 for loading, with a nose-like body 10 pointing in the direction away from the surface 2 for loading.

A preferred length-width ratio of each floor panel is approximately 2: 1, wherein the maximum length and width dimensions are chosen such that a single panel or a set of stacked floor panels 1 can or can be transported in a sea container or road vehicle. Such as dimensions of approx. 5 - 6 meters by approx. 2 - 3 meters.

In the embodiment shown, the floor panel 1 is also provided with a second liquid collecting gutter 11 extending along the fourth circumferential edge 7 and arranged in the floor panel 1 and open in the floor panel 1. This second liquid collecting gutter 11 opens out of 12 into the first liquid collecting gutter 8 and is closed at the second peripheral edge 5 14.

Along the third peripheral edge 6 extends a liquid discharge channel 15 arranged in the floor panel 1 and open from the surface 2 to be loaded. The first liquid collection trough 8 then opens into the liquid discharge channel 15. In the case of a floor panel without a second liquid collection trough 11, the first liquid collection trough 8 is closed on the fourth peripheral edge 7.

The surface 2 to be loaded is recessed relative to the first 4, second 5 and fourth 7 peripheral edge. In the embodiment of the floor panel 1 shown, the surface 2 to be loaded is located further deepened from the fourth peripheral edge 7 to the third peripheral edge 6 in three steps 16, 17, 18 respectively. In this way a slope is created for discharging to the liquid discharge channel 15 liquids and other substances present on the surface 2 to be loaded, such as clay, sludge, dust and other dirt, etc.

In the embodiment shown, the floor panel 1 is provided on the first 4, second 5 and fourth peripheral edge 7 with an integrated edge or sill that is raised relative to the surface 2 to be loaded, respectively indicated by reference numerals 19, 20, 21 of the same height. from the unloaded surface 3 of the floor panel 1.

The height of the sill 19, 20, 21 is chosen such that the surface 2 of the floor panel 1 to be loaded can receive a desired, determined amount of liquid, without this liquid flowing over the sill 19, 20, 21 in the first and second liquid collection trough 8, 11. For example, a quantity of approximately 100 liters.

As shown, the raised edge or sill 19, 20, 21 obliquely connects at an obtuse angle to the surface 2 of the floor panel 1 to be loaded.

The liquid discharge channel 15 ends at each end 22, 23 thereof in a tubular or semi-tubular outflow or inflow opening. With the floor panel 1 shown in figure 1, semi-tubular outflow openings and inflow openings are shown.

The first and second liquid collection troughs 8, 11 and the liquid discharge channel 15 form an integrated liquid collection and discharge system accessible from the surface 2 of a floor panel 1 for liquids accessible.

The dimensions of the nose-shaped body 10 of the floor panel 1 are such that it engages appropriately in the first liquid collection trough 8 of another floor panel for thus mechanically coupling adjacent floor panels, as shown in more detail in Figure 2.

Figure 2 shows a fluid-tight coupling between two partially shown adjacent floor panels 1 and 1 "each of the type shown in Figure 1. The floor panels 1 and 1 'are mutually connected and coupled to one assembled liquid-tight floor provision 25 because the nose-shaped body 10 of the one floor panel 1 protruding from the flange on lip 9 engages the first liquid-collecting trough 8' along the length of the second peripheral edge 5. along the length of the first peripheral edge 4 'of the other floor panel 1'.

Liquid from the surface 2 to be loaded via the gap or opening 24 formed at the boundary of the engaging floor panels 1 and 1 "is collected in the first liquid collection trough 8". The flange or lip 9 of floor panel 1 fits tightly onto the adjacent first peripheral edge 4 "of floor panel 1". This adjacent connection is first and foremost arranged such that a vertical movement transversely of the surface 2 of floor panel 1 to be loaded also rests on floor panel 1 "whereby the force is distributed over both floor panels 1 and 1". Any horizontal movements are limited by the fitting engagement of the nose 10 and the first liquid collection trough 8 ", whereby the mass of the individual floor panels placed against each other does not allow any further movement.

The thickness of the flange or lip 9 and the nose-shaped body 10 on the second peripheral edge 5 and the depth of the first liquid collection trough 8 or 8 'and height of the first peripheral edge 4 or 4' bounding this liquid collection trough, all measured in the direction transverse to the surface 2 to be loaded are of such dimensions that floor panels 1 and 1 'coupled to their respective first peripheral edge 4 or 4' and second peripheral edge 5 or 5 'in one plane, i.e. evenly without height transition, as shown in figure 2.

Although not explicitly shown, the depth of the second liquid collection trough 11 and the height of the fourth peripheral edge 7 bounding this second liquid collection trough 11 are provided with dimensions or recesses such that floor panels 1 coupled to their respective fourth peripheral edge 7 are provided with a corresponding second liquid collection troughs 11, coupling plate engaging from surface 2 to be loaded also also smoothly and evenly.

Such a coupling plate fulfills the functions of both mechanical coupling and over-casing, while maintaining all mechanical, chemical and durability preconditions. The coupling plate can in principle be closed or be provided with openings for collecting liquid from a coupling plate in a second liquid collection trough 7 and is preferably made of a suitable resistant material, such as stainless steel, stainless steel.

The floor panel 1 shown in figure 1 is provided with further mechanical coupling means for mutually connecting floor panels 1 and / or for coupling objects with a floor panel. In the embodiment shown, the floor panel 1 for this purpose comprises coupling elements spaced from and along at least one peripheral edge, fixed in the floor panel 1 and accessible from the surface 2 to be loaded, such as threaded bushes, bayonet connection bushes and similar coupling bushes 26. preferably releasably coupling fasteners, such as metal strips or strips, that further connect adjacent floor panels mechanically to each other to sustainably meet requirements and standards of the dynamic, static, mechanical, thermal, and chemical properties of the composite floor system.

For this purpose, in the floor panel 1, 4 pairs of coupling sleeves 27, 28, 29, 30 are fixedly fixed in the floor panel 1 at a distance from and along third and fourth peripheral edge 6, 7.

The frame 59 thus formed for mounting the window or screen panels (not shown) therein or close to the raised edge 50, 50 'or the liquid discharge channel 45, 45' of the floor panel 41, 41 'on the surface 2 to be loaded , 2 'on. The edge 50, 50 'herein forms a stop for the screen wall with which on the surface 2, 2' to be loaded an adequate collection of liquid and other dirt and the like that ends up on the window panels is achieved, as schematically indicated by the reference numeral 74.

The coupling plates 65, coupling pieces 66, coupling strips 70, uprights 60, 61 and cross connectors 62 as well as the bolt / nut connections used are preferably made of stainless steel or another material that is difficult to corrode. The window or screen panels can be made of a suitable light-transmitting plastic such as polycarbonate or glass or from a non-light-transmitting plastic or metal, such as for example aluminum. Of course, in the manner described, for example, a complete covering of the floor provision can also be realized.

The liquid-tight floor panel 1, 41 preferably consists as a whole of a body composed in its base of a glass fiber-reinforced matrix of plywood wood panels, surrounded on all sides by a closed composite skin of one or more layers of glass-fiber cloth, with the aid of a vacuum glue resin the distinctive components are combined into one sandwich construction. This sandwich construction combines light weight, high rigidity and durability. This construction differs from common constructions made of plastics in that in the present invention no delamination occurs with a floor panel 1 and the composition, shape, stiffness and durability are permanently retained.

Composite consists mainly of glass fibers, such as E-glass fibers, C-glass fibers, ECR glass fibers, S-glass fibers, basalt fibers, carbon fibers, such as low modules, intermediate modules, high modules, high strength modules, polyaramide fibers with ultra-high molecular weight polyethylene (UHMWP ) and hybrids of such fibers. Furthermore, plastics consisting of primarily thermosetting polymers, such as polyester, vinyl ester, acrylate, polyurethanes, epoxies, are suitable. E-glass fibers in polyester are particularly suitable. For use in an environment where aggressive substances are treated, C-glass fibers in vinyl ester are suitable.

Combinations of the aforementioned or further fibers are also possible, as well as combinations of the aforementioned plastics Combinations of the aforementioned or further fibers are also possible, as well as combinations of the aforementioned plastics as well as combinations of plastic composite with metal products, such as steel products, including molded metal sheets of a sandwich construction as a hybrid form of a floor element.

The floor panel 1, 41 may contain further substances or layers such as anti-UV damage substances, for roughening a surface for anti-slip purposes, for preventing moss deposits, an anti-wear layer or dyes and the like for markings such as lines and / or planes. In particular, a liquid-tight skin extends over the surface 2 to be loaded and subsequently over the flange or lip 9 and the nose-shaped body 10 and into the liquid collection troughs 8, 11 and the liquid discharge channel 15, 45.

In more detail, each floor panel 1, 41 can meet the standard requirements for dynamic, static, mechanical, thermal and chemical loads. In this context, standard requirements are understood to include: TGB 1990; NEN 6702; NEN 6706; Eurocodes and CUR 96 that can meet a 600 traffic class.

In one embodiment, floor panels 1, 41 are manufactured with a thickness (or height) of approximately 7-9 cm. The floor panels can advantageously be placed on an existing paving of stone or the like, preferably via an intermediate cushion-shaped bottom layer 35 filled with sand 34 and built up from contiguous compartments 33, as schematically shown in Figure 2.

At the places where floor panels are connected to each other or merge with each other or where floor panels lie against each other, to further guarantee the liquid tightness of the floor provision, connection seams or cracks, including also the engagement of the flange or lip 9 of a floor panel in the first liquid collection trough 8 of another panel, be sealed or sealed by means of a well-adhering chemical-resistant joint compound or sealant. For example with a silicone sealing kit of the Ottoseal® S34 or similar type.

For the manufacture of a liquid-tight floor facility with sufficient bearing capacity for floor panels on an existing pavement or substrate, the invention in particular provides a method in which a pressure bed is formed on the pavement or substrate over the entire surface of the floor facility to be manufactured.

For this purpose, a solid cloth or tarpaulin of, for example, polypropylene or corresponding plastic material is first spread on the pavement or substrate. The dimensions of the fabric are at least twice the dimensions of the floor provision to be manufactured.

A bed of sand, granulate or, preferably, a bed of sand mixed with cement is applied to half of the canvas, with a thickness sufficient to eliminate unevenness of the substrate and to prevent a fall or slope of a few degrees in the direction towards obtain the liquid discharge channel 15, 45, for discharging liquids which end up on the surface 2 for loading and the like. This bed is laid in an adjusting frame whose dimensions and contour correspond to the dimensions and contour of the liquid-tight floor provision to be manufactured. The height of the adjusting frame or the pressure bed depends on the unevennesses in the substrate and the desired fall or slope.

After the bed is ready, the other half of the cloth or tarp is applied over the bed, of course without disturbing it and the cushion-shaped bottom layer thus formed is closed at the edges by fixing the cloth or tarp to the adjusting frame. A single cushion-shaped bottom layer is hereby obtained, similar to the cushion-shaped bottom layer shown in Figure 2, but with only one single closed compartment. Subsequently, a liquid-tight floor provision is laid on the pressure bed thus obtained with floor panels according to the invention, as described above.

The adjusting frame can be made of, among other things, wood but also of plastic or metal and the tarpaulin or cloth can be attached to the adjusting frame by stapling, screwing or otherwise.

Such a substrate forms an excellent and durable pressure bed, because the filling of the bed cannot wash away and that can be manufactured quickly and at acceptable costs and can also meet the highest load requirements that can be imposed on a floor provision according to the invention.

The invention also provides for the marking or identification of each floor panel with its own unique identification, in particular an automatic, remotely readable identification, such as, for example, a high-frequency radio tag, a so-called RFID tag 75, 75 ', which identification by way of of example with broken lines in Figure 4. With this, each floor panel can be recognized for, for example, inspection purposes, and the age, usage history and other details of a floor panel can be linked to this and kept in a computer file. Such an RFID tag, which is preferably of the passive type, can be integrated into the material of the floor panel or, for example, into a logo or emblem or the like to be applied thereto.

For a person skilled in the art on the basis of the embodiments described above, further changes and modifications are conceivable, which further changes and modifications are all understood to be included in the appended claims.
