Description

Cover plate

The present invention relates to a kind of cover plate of the building that may be installed underground.

Become known for being arranged on the equipment of underground or (special) irrigation canals and ditches for surface drainage and well, it has cover plate to cover Lid.These deck portion ground are driven through thereon by motor vehicles, but are also particularly trampled thereon by pedestrian.Once cover plate is wet Or dirty, then have the danger slipped, and it is also possible to can be injured.

The cover plate of known multiple form of implementation, particularly grid.Such as DE 1 853 985 U, DE 20 2,006 014 Grid shown in 082 U1, DE 89 09 748 U1 or DE 1 876 986 U, these grids are furnished with (wedge shape) channel-shaped surface Structure or the projection with triangular-section.In addition known ditch for example from German design patent M 9 505 847 Drain cover plate, it has projection, and described projection can ensure that anti-skid safety.

But known arrangement can only be limitedly anti-skidding.Particularly when cover plate is made up of plastic material, particularly injection mo(u)lding When it is easy to will make dirty, this can make the dangerous increase of accident.

In addition although known anti-skid structure internally would generally provide enough skid resistances in the such as swimming pool of region, its The middle clean water with not polluting granule washes away grid.But for example in the outer region once polluting granule contact grid, that Known macrostructure (being just for example known channel-shaped thing (Riffelung)) and microstructure (indenture (Narbung)) Filled and led up due to polluting the entrance of granule-water-mixture, therefore no longer had enough skid resistances.

The task of the present invention is, provides a kind of cover plate of aforementioned type, to have been still ensured that with cost as few as possible The anti-skid safety being improved.

This task is especially by the building that may be installed underground, particularly well, drainage by well points, drainage ditch or similar The cover plate of drainage arrangement is achieved, and it has：Can be for the surface travelling of trampling and drive, this surface has relatively low the Planar structure in one plane；And, the projection with projections mantle surface, these projections mantle surface are located in described plane The second higher plane more than structure it is characterised in that projections mantle surface has anti-skidding surface texture, this surface texture There are multiple single projections, the wherein volume of air in single raised lower section and single raised volume ratio Vv/Vm is preferably (0.01 to 0.5)/(0.001 to 0.05), preferably (0.02 to 0.2)/(0.002 to 0.01).

Therefore, anti-skid structure extends vertically upwards so that will have substantially more from original cover plate plane (relatively low plane) Many pollution granules just can be filled and led up the region between anti-skid structure and thus improve skid resistance.

The more important of the therefore present invention is, even if pollution granule is brought in anti-skidding surface texture, these are dirty Dye granule can easily be rinsed out or also can be moved in region relatively low between bumps by trampling.

Preferably, single projection has different maximum heights.Thus achieve, though when pollution granule be deposited on anti-skidding When in the differing heights region of structure, these pollution granules also have different height and again voluntarily play in this way Anti-skidding effect.

It is possible that in the first relatively low plane, relatively low planar structure there is anti-skidding surface texture, this table Face structure is less coarse compared to the non skid matting structure of projections mantle surface.Planar structure positioned at lower for example can have There is indenture to realize desirable appearance, for example, obtain casting of appearance of cast, and for improving roughness and being achieved in planar structure Non-skid property.

Preferably, maximum height is arranged in the distribution from Sz=150 μm to 1500 μm, is preferably between 230 μm and arrives In distribution between 1000 μm.Described measurement parameter is (as point out in following description and Patent right requirement Calculating parameter) derive from DIN EN ISO25178.Wherein explicitly point out described parameter, simultaneously in the standard also to measurement Method is described, and described measuring method has drawn parameters presented below.

Single raised or its size distribution can regularly be carried out.It is preferred that selecting random point in the plane One of cloth is distributed, so that being also equipped with height in smaller area have low single projection.

These single projections can be set to different shape (from horizontal profile).But preferably single projection is configured to gold Word turriform or taper.

Single raised maximum sinking height (it is also referred to as recess heights) is Sv=50 μm to 500 μm, preferably 85 μm To 310 μm.This scope is unexpectedly proved to be particularly advantageous.

The roughness value of surface texture is preferably Sa=10 μm to 200 μm, preferably 15 μm to 90 μm.The drawing of surface texture The aspect ratio (being also referred to as the transition face ratio of the development on limited scale surface according to DIN EN ISO 25178) stretched is preferably Sdr=20% to 300%.The peak density that surface texture preferably has is Spd=0.5mm^-1To 20mm^-1, preferably 1mm^-1Arrive 10mm^-1.

Size range above-mentioned unexpectedly has special effect, on the one hand hardly occurs damaging on top Wound, and on the other hand can realize enough skid resistances and self-purification capacity (Selbstreinigungskraft).

To elaborate the present invention by shown accompanying drawing below.In figure illustrates：

Fig. 1 shows the top view of grid used by drainage ditch,

Fig. 2 shows the sectional view of the II-II line along along Fig. 1, and

Fig. 3 is to amplify the III region illustrating in Fig. 2.

As can be appreciated from the illustration, the form of implementation of grid 10 depicted herein has supporting structure, and this structure has There is surface 11, this surface is located in the first relatively low plane.Described surface 11 is interrupted by discharge outlet 12 and is constituted smooth putting down Face structure 13.At this moment, described planar structure 13 has the surface roughness of very little, as example as surface can be formed, institute State surface roughness to produce by injection molding technique.

Surface 11 is provided with bar-shaped raised 14, its projections mantle surface 15 has described roughness, and it is particularly In injection mo(u)lding by be molded shape correspondingly molding and obtain.Projections mantle surface 15 has single in this case Raised 16, as shown in figure 3, these single sharp single cones that project through various height and various produce.

It is ensured that by described molding, the pollution granule on the one hand touching projection 14 is easy to be rinsed and defeated Deliver in smooth planar structure 13.It is discharged to polluting granule discharge outlet 12 from smooth planar structure 13, so that A kind of self purification is produced by selected structure here.Even if when trampling, the power by occurring can reduce pollution The accumulation of granule, because these pollution granules can be extruded projections mantle surface 15 and be transported to smooth planar structure 13, with Just eventually arrive at discharge outlet 12.
