Definitions

  • the invention relates to a sports hall floor according to the preamble of claim 1 and a method for producing a sports hall floor.
  • the basic structure of sports hall floors is described in DIN 18 032.
  • an elastic layer on a sub or raw floor, for. 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.
  • the elastic mat 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 polyurethane two-component casting compound as the basis for the pressure distribution plate to be cured, this mass under the influence of moisture, for. 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.
  • 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 hung up and then using of a pressure sensitive adhesive, the second plastic layer is applied to the first plastic layer and glued to it, and in which an upper covering is subsequently arranged on the second plastic layer by means of an adhesive, the separation 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 ⁇ 10 ⁇ 3 ⁇ 4 / ° for polyethylene and 80 ⁇ 10 ⁇ 3 ⁇ 4 / ° when using polyvinyl chloride.
  • 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, which are glued to one another over the entire surface and receive an upper 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.

  • two such layers of polyolefin sheets are applied, according to a further embodiment three layers of polyolefin sheets are applied, the layers being placed floating on the elastic. Adjacent layers of polyolefin sheets are glued together over their entire surface using a preferably waterproof adhesive.
  • the individual plates of the different layers are laid on the elastic layer in such a way that the joints of layers lying one above the other are offset from one another.
  • the plates of at least one layer are provided with a fleece on their surface facing the next layer, which is preferably pressed or introduced into the plate surface during the manufacture of the plates.
  • This fleece practically contributes to an increase in 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.

  • 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 consisting of the two plastic layers layer.
  • 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.
