DE2004831A1 - Sports facility ceiling or surface and process for its manufacture - Google Patents

Description

Priority: February 3, 1969, France

The ^ invention relates to ceilings or coverings for sports facilities » which are formed from a skeleton of different materials, which by a binding agent for example Cement, a product containing hydrocarbons, synthetic or natural resins, clay or the like, firmly mixed with one another are bound, u, are tight against water that is on their surface is retained after rain or rinsing in such a way that these places are very often unusable.

According to the invention, a more flexible, grippy or Proposed non-slip flooring or a floor cover that is permeable to water and, however, immediately after

rain or rinsing with large amounts of water is usable.

The method according to the invention for producing the ceiling consists in »making a careful selection of the materials that make up the skeleton and of the binding agent to use them in such a way that in hatred and in total thickness The ceiling cavities are left, which are in communication with each other and with the outer surfaces.

'With exclusion sätfinlicher powdery elements is homogeneous mf the ceiling or lining skeleton or consists of a mixture of stone chips, cork, rubber, cured synthetic resin or the like having a G-ranulometrie mm and between about 3 to 6 various and irregular geometric forms such that despite any confusion or entanglement in stacking, they leave intercommunicating voids.

The liquid binding agent must be chosen in such a way that a surface layer is formed on the chippings and among each other When setting, the split or small soalag file is firmly connected without the possibility of the connection Uk of the pores or cavities being clogged or changed.

The binder can be homogeneous or natural from a mixture or synthetic thermoplastic resin, an emulsion or a solution of a product, which completely sets by leaving a certain yield and hastiness, the rest, if necessary can be regulated with the addition of all catalysts or adequate hardeners.

Covering or ceiling according to the invention can be on the ground or Soil can be made by placing on the expedient

porous and water-absorbing support area one layer suitable thickness of selected grit, which is impregnated or sprinkled with binding agent, u (is poured, whereby stirring or mixing of the mass follows and then the surface is leveled, whereby the covering ^ · then cover itself until the end of the setting.

Topping or ceiling can also be made in the factory in the form of Sheets or plates of the desired thickness are produced, the skeletal chippings impregnated with binding agent being poured into a mold placed on a porous work surface

becomes and in the mass with subsequent adjustment of the ^

Surface is stirred and then until demolding after ™ the beginning of the setting of the binder

The manufacture can also be done in the workshop, a Layer of grit impregnated with binder is spread out and leveled on a carrier conveyor belt, which passes a heated zone at the end of its travel path the setting and the mutual consolidation of the chippings to accelerate, with the covering carpet produced in this way at the end of the path separately from its carrier received and on roll., is placed.

The selection of the grit, its granulometry and the Proportions of the femoral as well as those of the binders, their additives and hardeners, of the possibly-provided The heating time and temperature are reduced on a small scale performed preliminary tests, with thicknesses, strength, consistency and the flexibility to be achieved accordingly the standards and regulations are taken into account (consistency the clay soil, for example).

Laying the in the factory in the form of panels or The covering made of panels consists in placing them with abutting edges on the water-permeable substrate

009837/1343

rich, which is to receive the covering, and fix the edges by gluing against each other.

The laying of the in the factory in the form of a rolled sports field carpet produced flooring consists of rolling it onto the porous surface that is intended for it Pick it up and divide it by gluing the edge against it Edge to unite two adjacent unrolled strips.

In addition, the topping made in the factory can be attached to the porous support using any suitable adhesive.

An example embodiment of the invention will now be explained in more detail with reference to the accompanying drawing, in the

Fig. 1 is a perspective schematic representation of the Production of a covering panel shows;

Fig. 2 shows schematically & NEN vertical section through flat this plate when it is laid on its sub-floor.

In the simplest method shown in Fig. 1, a frame 1 serves as a mold for the batch or mixture 2, which forms the covering plate, the shape of which is selected in a rectangular field.

Part 3 of the frame 1 has been broken away in order to show its structure; the material can be wood, metal or plastic be used. Detachable hinge joints (not shown) can be provided at the angles in order to remove the mold to facilitate after making the plate. The frame 1 is on a work area, not shown

009837/1343

or work table. The inner walls are in front of been greased for demoulding.

The previously prepared moist mixture is placed in the rack 2 made of granules and binders.

To form this mixture, you dose amounts of the or of granular materials, which are then dedusted or sifted or washed to find only the items more appropriate Withhold granulometry, for example 5 to 6 mm. These granules are placed in a tub in which the liquid binder is added in a dosed amount sprayed on, for example by stirring the mass, all surfaces of the granules being well coated with binding agent without sprinkling would have to. These granules are then poured into the frame 1, where they are carefully distributed and tamped down The surface of the plate is finally made by means of a board or peeled off or calibrated from a plane. The setting or hardening of the binder can now take place go, followed by demolding. The panels produced

are directly on the Trägeruijgrund with abutting each other Edges used, which are set against each other by means of the adhesive.

To make the work table faster for other work processes To get free, a stiff intermediate piece can be placed under the frame which forms the provisional! carrier and all possible expedient manipulations, incl. Storage, enables.

According to the available granulometry and characteristics the softness or compliance or the one desired Relative compactness, the fresh mixture can shaking movements immediately after being introduced into the rack or even moderate vibrations without any indispensable resistance to water of the end

According to another method of production, the finished slag cake be placed in a zone or a heating cabinet that allows faster setting of the binder.

In addition, all catalysts or hardeners can be added to this binder, which are advantageous for a accelerated and well done setting.

All binders that are well adhesive and resilient after setting are suitable, provided that they do not change when exposed to the weather and are insensitive to water.

The production of the covering or the ceiling can also be carried out continuously in the form of a sports field carpet. In this case, the work table is preferably through a Conveyor belt similar to a joint, which is also made of metal mesh

can exist, and, on both sides a longitudinal one geoITaet

Edge part trägV. The fresh mixture of granules and binders is abandoned at the beginning of the manufacturing process; at a later point the tape will be shaking or exposed to vibrations that lead to a certain setting or compression, with the excess one The accumulation-forming material is scraped off and the tape then runs into a heating tunnel, which is used for setting and Curing and! Drying takes care of before the covering or ceiling tape is rolled up.

Daa laying the floor covering or the ceiling carpet on the In this case, the area to be covered is quicker and more economical than in the case of panels.

In both cases, the covering area 4 (borrowed FIG. 2) must be used a relatively uniform itarren support 5 rest, which is

On the other hand, it has good permeability to water. A porous concrete, as shown, is perfectly suitable, provided that that he is trained so that the water can easily run off.

The thickness of the pavement should match the desired goal and the materials used.

] For tennis courts, a covering made of plastic granules has been used essentially cubic in shape and with a thickness between about 10 and 20 mm is extremely satisfactory shown.

The method according to the invention also includes all variants in the execution and continuous improvement of the production the agglomerates.

The invention also relates to all coverings or sports field ceilings produced in the manner described above.
