Definitions

  • the invention relates to a sports hall floor according to the preamble of claims 1 or 2, and to a method for producing a sports hall floor according to the preamble of claims 14, 17 or 18.
  • a sports hall floor according to the preamble of claim 1 is known from FR-A-2 621 056.
  • This sports hall floor has a polyurethane foam layer with a glass fiber grid on top, and a polyester layer. There are polyurethane layers above the polyester layer. The polyurethane foam layer with the glass fiber grating is firmly connected to the polyester layer by means of polyurethane resin.
  • the basic structure of sports hall floors is described in DIN 18 032. With such sports hall floors is an elastic Layer on a sub or raw floor, e.g. B. screed applied.
  • the elastic layer for. B. in the form of an elastic mat, which can be made of foam, glued to the screed.
  • On the upward-facing surface the elastic mat is covered with a fabric, e.g. B. from glass fibers, polyester fibers or the like. Provided.
  • This fabric can either be laminated onto the elastic mat or is glued to the elastic mat on site. Subsequently, a liquid plastic with a thickness of 2 to 3 mm is applied and cured to produce a pressure distribution plate on the fabric-reinforced elastic mat.
  • Another disadvantage is that when using a two-component polyurethane casting compound as the basis for the pressure distribution plate to be cured, this compound under the influence of moisture, eg. B. humidity, gases such as carbon dioxide, cleaves, which leads to the formation of bubbles in the plastic layer and affects the mechanical strength of the pressure distribution plate to be produced.
  • moisture eg. B. humidity, gases such as carbon dioxide, cleaves
  • a method for producing a sports hall floor is known from DE-PS 26 23 321, in which an elastic layer is placed seamlessly on a sub-floor, after which to form a load distribution layer consisting of a first and a second plastic layer, the first plastic layer on the elastic layer and then using a pressure sensitive adhesive, the second plastic layer is applied to the first plastic layer and glued to it, and an upper layer is then arranged on the second plastic layer by means of an adhesive, the separating points between adjacent layers or layers being offset from one another.
  • Two plastic layers made of PVC or hard polyethylene joined together by a pressure sensitive adhesive serve as the load distribution layer.
  • a load distribution layer formed in this way has the disadvantage that it has a high coefficient of thermal expansion, which is 200 X 10 -6 / ° for polyethylene and 80 X 10 -6 / ° when polyvinyl chloride is used.
  • the use of such materials for the load distribution layer has the consequence that the floor reacts sensitively to temperature fluctuations and warping in the area of the load distribution layer with respect to the sub-floor or possibly also to the top covering cannot be ruled out.
  • Another problem can arise with the known floor through the use of the pressure sensitive adhesive which is to be applied to the respective layers or layers at the construction site and which is undesirable on the one hand because of its solvent content and on the other hand does not guarantee the required adhesive strength.
  • DE-PS 22 21 761 describes a sports floor or a vibrating floor in which two layers of chipboard are used as the load distribution layer can be used, which are glued to each other over the entire surface and take up a top covering on the top.
  • the chipboard is glued to the elastic layer.
  • the invention has for its object to improve a sports hall floor of the type mentioned in such a way that the above difficulties and disadvantages are eliminated.
  • the invention creates a sports hall floor with a high adhesive strength between the plates of layers lying one above the other, which results from the use of a glass mat reinforcement, which contributes to an increase in the surface roughness and enables full-surface, firm bonding of layers lying one above the other.
  • the polyolefin sheets preferably in the form of polypropylene sheets, which are prefabricated and placed on the elastic layer at the construction site, there are no difficulties with regard to an uneven material layer. Due to the weight of the panels plus the top covering to be applied, the sports floor, consisting of the individual layers of polyolefin panels, lies floating and flat on the elastic layer.
  • Another advantage is that polyolefin sheets can be disposed of easily and in an environmentally friendly manner.
  • Another advantage is the fact that polyolefin sheets are inexpensive to produce.
  • a method is to be created with which a sports hall floor that is largely unaffected by temperature fluctuations, but is nevertheless inexpensive, can be produced.
  • the invention provides a method for producing a sports hall floor, the coefficient of thermal expansion of which is significantly reduced in that the plastic layers used, preferably made of polypropylene, are reinforced with glass mats.
  • the integration of glass mats in the plastic layers reduces the coefficient of thermal expansion compared to pure polypropylene to around 1/5.
  • one of the glass mat-reinforced plastic layers forming the load distribution layers is prefabricated in that a pressure-sensitive adhesive layer is applied by lamination or preferably with the aid of a press. This ensures that a desired intimate connection between the two layers forming the load distribution layer is achieved and the manufacture of the sports hall floor at the construction site makes the use of liquid, optionally solvent-containing pressure sensitive adhesive unnecessary.
  • the film serving as a carrier film for the pressure-sensitive adhesive needs to be removed from the prefabricated plastic layer only on the respective side, after which a "gluing" takes place by pressing the prefabricated plastic layer onto the layer already provided.
  • the entire load distribution layer is prefabricated according to the invention, ie the load distribution layer consisting of the two plastic layers.
  • the carrier film holding the pressure-sensitive adhesive layer is removed, and the two plastic layers are then pressed together by a press, sandwiching the pressure-sensitive adhesive layer.
  • individual parts of a load distribution layer to be assembled at the construction site are obtained in such a way that the upper or lower plastic layer on the edge protrudes from the other plastic layer and, before assembly, the carrier film for the pressure-sensitive adhesive layer located on the above edge must be removed before the load distribution layer on the Construction site is assembled by overlapping assembly of such pieces.
  • the two glass mat-reinforced plastic layers are joined instead of using a pressure-sensitive adhesive layer to form prefabricated pieces of the load distribution layer in that the mutually opposite or at least one of the two surfaces of the plates resulting in the individual plastic layers are flamed and after softening Surfaces the associated plates are placed on one another under pressure.
  • Such prefabricated pieces of the load distribution layer are also formed so that one of the two plastic layers on the edge protrudes over the other plastic layer.
  • the respective surface is flamed by the edge-projecting section of the one plastic layer and thereby brought into a softened state before it is brought into connection with an equally flamed edge section of another piece and pressed together.
