Abstract

The invention relates to platforms perforated in the manner of a grate or grid, for combining with at least one collecting tub to be arranged thereunder in order to create a storage surface for containers having hazardous substances or having liquids that are hazardous to groundwater. The platforms consist largely of a plate having supporting feet arranged on the underside of the plate in a grid-like manner, which supporting feet keep the plate at a distance from a floor surface or from the tub bottom and ensure a high load capacity of the plate.

Description

Grid-like or grid-shaped perforated platform

The invention relates to lattice-like or grid-shaped perforated platforms according to the preamble of claim 1.

Containers containing hazardous substances or liquids hazardous to water must be stored or parked in such a way that any spilled liquids or hazardous substances can under no circumstances be released into the groundwater. For this purpose, it is generally known to form the Absteilflächen as drip pans, which are each covered by a grid. Then, liquids or hazardous substances are removed from the parked on the gratings containers or introduced into the containers, spilled liquids are absorbed by the aforementioned tubs and can then be eliminated from time to time according to the relevant regulations. To accommodate the gratings have on the market available drip trays at their tub edges molded receiving profiles, so that the gratings are held in a form-fitting manner. The disadvantage, however, is that the tub walls must be sufficiently stable in order to be able to absorb the load of the gratings and the containers parked thereon with dangerous goods or water-polluting liquids. In addition, the gratings must also have a high stability, so that they are sufficiently resilient even at areas away from the edge.

Furthermore, it is known to use Euro pallets in correspondingly adapted trays and to use as support or storage areas for containers with hazardous substances or water polluting liquids. Here is advantageous ensures that the walls of the tubs are loaded only slightly, but the Euro pallets can be stacked only very space when not in use.

US 2006/0070314 AI shows interconnectable platforms in which each platform has a grid-like structure, with multiple lattice planes superimposed and interconnected, and the lattice axes cross substantially diagonally to provide a particularly stable and highly resilient composite , For connecting adjacent platforms, each platform has eyelet-shaped receptacles on two side edges forming a platform corner into which adjacent platforms with feet arranged on the remaining side edges can be inserted. In the case of a combination of multiple platforms, care must therefore be taken that the next platform in each case is correctly attached to one of the existing platforms. Accordingly, a relatively large installation effort is necessary if several platforms to be set together.

In addition, the platforms of US 2006/0070314 AI can not readily be used in shallow trays whose floor plan corresponds to the floor plan of a single platform.

The US 3,702, 100 shows pallets made of plastic, which are stackable and formed for receiving with forklifts.

DE 39 34 134 AI shows gratings with arranged underneath collecting trays, which are suitable for receiving leakage liquids from containers, which are placed on the gratings. Notify Hard tubs are connected to each other by lines that pass through adjacent tub edges. In this way, it is ensured that each drainage liquid can be taken up by several trays and an overflow of a single tray is unlikely.

The object of the invention is to provide usable platforms in shallow wells, which can be connected in a particularly simple manner to virtually any size platform surfaces. It should be usable tubs with low weight and relatively low stability.

This object is achieved by the characterizing features of the new claim 1.

Preferably, the platforms are formed as molded plastic parts with molded support feet.

Furthermore, it is preferably provided to positively couple adjacent platforms with one another via connector plates which can be inserted with lower-side projections into the hollow cone stumps or support feet open on the upper side and rest on the upper sides of the interconnected platforms in the inserted state.

In the assembled state, the connector plates may be received in fitted recesses on the tops of the interconnected platforms so that the tops of the connector plates are aligned with the tops of the platforms.

The troughs assigned to the platforms are preferably coverable at their mutually adjacent tub edges with downwardly open U-profiles, these profiles being partially covered by the U-profiles The edges of the platforms used in the trays are secured in position. In this way, it is ensured that no hazardous or water-polluting liquid can get between the tub edges to the ground.

The trays preferably have slightly outwardly sloping sidewalls, so that the trays used for transport into each other can be conveyed as tray stacks.

In principle, however, it is also possible and advantageous to make the tubs foldable, since the loads taken up by the platforms are removed via their support legs or hollow truncated cones without loading the tub walls on the substrate.

According to a further preferred embodiment, it may be provided to form the bottom of the tub in such a way that it can be moved by the forklift of a forklift or lifting device in order to be able to lift and transport tubs with platforms inserted therein and containers placed thereon.

Incidentally, with regard to preferred features, reference is made to the claims and the following description in which particularly preferred embodiments are explained in more detail with reference to the drawing.

In the drawing shows

1 is a schematic side view of a platform according to the invention with associated tub, Fig. 2 is a plan view of the platform according to the arrow II in Fig. 1 and

Fig. 3 is a vertical section of the edges of adjacent platforms and adjacent tub edges and the platforms.

1, each platform 1 consists essentially of a plate 2 with arranged on the underside, in particular integrally formed support legs 3. These support legs 3 are preferably formed as hollow truncated cones, which are open at their upper ends, that is, the plate 2 has in the area the support feet 3 each have an opening 3 \ cf. In addition, the lower ends of the support legs 3 are preferably designed to be open. Instead or in addition, it is also possible that in the peripheral walls of the support legs 3, in particular in the region of the lower ends openings are arranged.

FIG. 2 now shows a plan view of a platform 1 corresponding to the arrow II in FIG. 1. The plate 2 of the platform 1 has respective openings 3 'to the below the plate 2 arranged support feet 3. In addition, in the plate 2 more grid-like arranged openings 4 are provided, can flow through the incident on the top of the plate 2 liquids.

The plates 2 of the platforms 1 preferably have at their plate edges shallow recesses 5 in the region of openings 3 'for the underside of the plate 2 arranged hollow support legs 3. These recesses 5 serve to receive connector plates 6, which engage with lower-side projections in the aforementioned openings. 3 'can be inserted within the recesses 5, such that the tops of the connector plates 6 are aligned with the tops of the plates 2 of the platforms 1. In this way, adjacent platforms 1 can be positively connected to each other. The platforms 1 can be used with their support feet 3 in collecting trays 7, which are shaped so that their tub edges are located just below the edges of the plates 2 of the platforms 1 used. On adjacent tub edges downwardly open U-profiles 8 are placed, as shown in Fig. 3. Once the platforms 1 have been inserted into the drip pans 5, the U-profiles 8 are each covered by the edges of the plates 2 adjacent platforms 1, so that the aforementioned U-profiles are positively secured in position on the tub edges.

If now placed on the platforms 1 containers with or for hazardous substances or water polluting liquids, it is ensured even with improper or careless handling that spilled hazardous substances or water polluting liquids through the openings 3 'and 4 of the plates 2 of the platforms 1 in the underneath arranged catch basins reach 7 and accordingly can not penetrate into the groundwater. Due to the grid-like arranged support legs 3, the platforms 1 can carry heavy loads, a load capacity of 1000 kg / m ² can be readily ensured, even if the platforms have very large sized plates and / or are made of plastic. Advantageously, the tubs or their walls do not have to absorb any loads, so that the tubs 7 can be produced in a lightweight construction and, if appropriate, can even be foldable to facilitate the transport or storage of the tubs 7.

Optionally, the tray floors can be designed with high load capacity and shaped so that they can go under with lift forks of forklifts or lifting devices, so that the respective trough 7 together with the platform 1 used and optionally together with a on the Platform 1 parked container for hazardous substances can be lifted and transported.

The platforms 1 are not limited to use together with the drip pans 7. For example, the platforms 1 can also be used for producing a cavity floor in buildings, in which case the cavity between a building ceiling and a building floor and the plates 2 of the platforms 1 can be used for installation purposes or for the implementation of hot air or the like, for example to allow underfloor heating in workshop halls.

Preferably, the platforms have 1 length and width dimensions such as Euro pallets (120 cm x 80 cm) or halved, quartered u.s.w. Dimensions (80 cm x 60 cm, 40 cm x 30 cm, u.s.w.), The wells 7 may be provided in appropriate sizes.
