Definitions

  • the invention relates to a sports floor segment, for a surface elastic or combined quarter-elastic sports floor for use in facilities for multi-functional sport uses.
  • Multilayered structures for mobile floors are made of WO 2007/124980 A1 known in combination with relines. By locking strips and mandrels single plate segments are interconnected. This results in a complex production and installation of such floors.
  • the invention therefore sets in the task of a quick installation of a sports floor with high quality and under the requirements of DIN Regulation 18032-2 to allow.
  • the invention solves this problem by a sports floor segment having the features of claim 1.
  • a sports floor segment according to the invention has an elastic layer and a layer of a graded load distribution element.
  • the elastic layer provides for the power reduction, flexibility in the application of force and fits to unevenness of the underground.
  • the step-shaped load distribution on the one hand allows a uniform distribution of stress on the largest possible area of the sports floor and provides a hard support surface for applying a topping.
  • the surface of the load distribution element can also already be treated such that the load distribution element simultaneously assumes the function of a Nutzbelages the sports floor.
  • the sports floor segments are pushed over each other in the step-shaped area during laying, so that a uniform surface with constant material thickness is achieved over the entire installed area.
  • a sports floor, which was laid with the invention a sports floor segment is to ensure the current standard of DIN Regulation 18032-2 of April 2001 and avoid the outgrowth of mechanical connectors through cavities, such as in brackets.
  • the corresponding sports floor segments can be arranged side by side in such a way that a quick and uncomplicated laying of a sports floor is made possible.
  • the sports floors can have a low weight despite compliance with the DIN-appropriate functionalities.
  • a uniform force distribution over the entire width of the load distribution element can be carried out.
  • corresponding sports floor segments can be prefabricated by machine before laying out in the appropriate sports venue. Therefore, the sports floor segments are suitable for mass production, resulting in additional cost savings.
  • the individual sports floor layers do not have to be delivered individually, but are already delivered in prefabricated sports segment construction. Thus, a completely finished area elastic sports floor can be installed by the element construction in a few hours.
  • a corresponding top document for example linoleum-plastic coverings or parquet and the like may be made by the sports venue operator or by the craftsman following the laying out of the sports floor segments.
  • the corresponding sports floor segments are joined together on site and fastened together in such a way that they uniformly cover a complete sports floor.
  • the load distribution element is formed from two construction plywood panels, since these plates payloads can be distributed to each other in such a way that a force reduction of 53% according to DIN 18032-2 is achieved.
  • Each plywood veneer plywood is multi-layered, preferably 3-12-layered and glued.
  • the construction plywood panels are arranged offset from one another in such a way that a step-shaped construction of the load distribution element for connecting individual sports floor segments is achieved.
  • the step-shaped construction forms a two-sided stepped rebate so that a shock projecting from a sports floor segment comes to lie on a recess surface of the next sports floor segment and both surfaces can be connected to one another by gluing and / or latching means.
  • the plywood panels are thus bendable and can distribute load effects well.
  • construction plywood panels are glued so that they form a continuous load distribution unit. This is done only by compressing both construction plywood panels at pressures between 30 and 200 bar, preferably 80 to 130 bar, thereby obtaining a similar strength as any plywood board taken alone.
  • the elastic layer consists of a plastic whose physical properties can be varied by chemical modifications or physical effects.
  • a corresponding plastic foam can consist particularly advantageously of at least one reticulated PUR (polyurethane) plastic foam.
  • Other plastic foams for example Polyester foams or PolyeterCoume or polyethylene foams can also be used in this application, both individually and in admixture, for example as a co-polymer.
  • additives for example, activated carbon, cellular rubber, PVC, cell plastic or melamine resins can be used.
  • the reticulation of the foam to a voluminous filter or lattice foam is particularly advantageous at elevated gas pressure, whereby the polymer composition is again blown up and thereby obtains a solid, but voluminous structure.
  • the sports floor segment can already be provided with a top covering made of plastic or linoleum as a covering on delivery.
  • a sealing material may be introduced between the joints of the individual sports floor segments in order to seal intermediate spaces of the individual sports floor segments.
  • the elastic layer at least partially consists of a recycled foam.
  • an advantageous CO 2 balance is already achieved during the production of the corresponding sports floor segments.
  • the sports floor segment has all the sports-functional properties according to DIN 18032-2 of April 2001, thus can be installed in all sports halls and avoids injuries of athletes there by its high protective function.
  • the fire protection class B1 includes the substances which are flame-retardant. These are materials such as: Fire-resistant wood-based materials, hard foam plastics. A fire must be after that even after removing one Extinguish fire source. This is particularly important in large events such as Basketballbundesligen or indoor football tournaments in which the risk of fire, for example, by illegal firecrackers or the like is very high and can not be completely avoided.
  • the sports floor segment is either surface elastic and / or combination quarter elastic.
  • the surface elasticity is characterized by the fact that the load is distributed over a particularly wide area. This is particularly advantageous in games in which the ball should hit the sports floor as naturally as possible and be reflected by this again. For point elastic sports floors, it may happen that the ball receives a twist or similar game disturbing properties.
  • a ground support layer for example made of chipboard or fleece underlay, advantageously allows additional flexibility to prevent cavities and to adapt to the substrate when laying the boards.
  • the floor support layer is glued or glued to the elastic layer.
  • FIG. 1 shows a surface elastic sports floor segment 10, which is composed of several layers. It has an elastic layer 2, which in the exemplary embodiment is an organic filter foam whose structure has been reticulated and blown up by increased gas pressure.
  • the foam has a density of between 55 and 5 kg / m 3 , preferably between 65 and 85 kg / m 3 .
  • the foam layer has a compression hardness of more than 5 kPa, preferably more than 10 kPa, and the compression set modulus is less than 0.2 N / mm 2 , preferably less than 0.1 N / mm 2 .
  • the tensile strength of the foam is in the range 10 to 40 kPa, preferably 20 to 30 kPa with an elongation at break between 5 and 50%, preferably 20 to 35%.
  • the air permeability of the reticulated foam for example, 350 1 / min / dm 2 , but can vary greatly by different colored aggregates.
  • a Holzkaltleim is used, which is also used to connect the individual sports floor elements 10 with each other.
  • the wood cold glue corresponds in heat to the European test standard 14257 with respect to its heat bonding strength, the heat resistance of the adhesive being between 5 and 15 N per mm 2 , preferably between 7 and 9 N per mm 2 .
  • the test of the adhesive is carried out according to the Test Guideline Watt 91 and also tested in accordance with the guideline "Determination of the Adhesive Strength of Longitudinal Joint Tension on Heat".
  • Fig. 2 shows that both construction plywood panels are arranged offset from one another such that the connection unit has at its edges the same size shocks 7 and 8 Aussparungs vom. These bumps and relief surfaces have a surface of x * y and form a shiplap 7, 8.
  • the total thickness z of the sports floor element is between 10 and 80 mm, preferably between 20 and 40 mm.
  • the surface of the sports floor can also have a plastic covering, which is applied without additional elastic layers on the wooden surface of the sports floor. Also conceivable as elastic flooring is linoleum.
  • the upper and lower structural veneer plywood panels are bonded together to a load distribution element so that additional stapling of the two panels to increase joint strength becomes unnecessary.
  • the elastic layer for example made of reticulated lattice foam, can also be laminated or glued to the plywood load distribution element from below in the factory.
  • all the elements of the sports floor element are already glued or glued together over the entire area in advance, which in each case the laying of the individual elements, the bonding of these individual elements together and the subsequent stapling of the individual elements deleted together.
  • a stepped rebate is a surface connection of two plates
  • the substructure which causes the compliance of the bottom surface, must not change significantly in their behavior under dynamic or static loads.
  • DIN V 18032-2 states that joints in the substructure must permanently withstand the aforementioned stresses, bonds must be permanently elastic, they must neither be reduced in their strength by aging nor become significantly brittle, hardened or softened.
  • Chipboard must comply with DIN 68763 and construction plywood panels of DIN 68705-3.
  • the sports floor segment (10) may additionally have a floor support layer 1 for resting on a substrate, for example in a sports hall, which is glued to the elastic foam layer 2.
  • Sports floors are generally classified into four different categories, which differ in their behavior in applying a point load.
  • An area elastic sports floor for example, distributes the power of point load by bending over a relatively large area around the load application point, whereas a point elastic sports floor bends only near the load application point.
  • a combined elastic sports floor is a surface-elastic sports floor with a point-elastic wear layer, which, when applying a point load, encompasses both a local area and a larger area the load application point bends, whereas a mixed elastic sports floor is primarily a point elastic sports floor with a surface stripping component.
  • FIG. 4 There are different deformation troughs for different sports floors in the formation of a deformation trough.
  • 4a) shows the deformation of a surface-elastic sports floor, 4b a point-elastic sports floor, 4c a combined-quarter-elastic sports floor and 4d a mixed-elastic sports floor.
  • the sports floors 4c and 4d combine the features of the other two sports floors, each with one property outweighs.
  • the composite construction can be constructed of three materials, namely a wood or plywood material, a wood glue and a reticulated plastic layer.
  • a bottom-side thermal insulation is ensured by the plastic layer.
  • a feature of a sports floor under dynamic load is its ability to absorb the impact and, for example, return the ball to the impacting object.
  • This sports floors are exposed to different temperatures, which makes the respective sports floors at low temperatures harder and at high temperatures softer.
  • Further criteria for a sports floor are, for example, the force build-up or the resistance to a rolling load, which are explained in more detail in the DIN 18032-2 for the respective sports floor. This applies in particular to surface-elastic or combined surface-elastic sports floors, in which a force reduction value of more than 53% takes place within the first three milliseconds, and thus ensures a sufficient protective function.
  • An optimal sports floor protects against injuries.
  • the factor of the protective function has the highest priority in the choice of the sports floor. For example, vibrating trays have a much too high weight of up to 35 kg per m 2 and are extremely sluggish due to this mass.
  • a sports hall floor fulfills the European standard 14904. Due to its layer arrangement, a corresponding sports floor has a thickness of at least 15 mm, preferably 20 mm. With such thicknesses of sports floors, it is also not trivial that the sport-functional properties in area-elastic sports floors according to the already mentioned DIN EN 14904 and DIN 18032-2 remain intact.
  • the permanently installed built-in sports floor with the sports floor segments according to the invention enables these sports functionalities. Mixed and combination-elastic sports floors could also be feasible when applying a suitable upper class.
  • a sports floor with the sports floor segments according to the invention by a pretreatment such as grinding or smoothing a concrete floor or the like. Thereafter, a sports floor segment is created on the next and possibly adjusted beforehand at the edges. And both sports floor segments are connected to each other via the rebate folds. Subsequently, a stapling and / or gluing of the two-sided stepped folds of both sports floor segments. Finally, when sports floor segments are laid over the entire surface of the hall floor and connected to each other, an upper surface can be applied. This ensures the grip strength of shoe soles or the like.
