Definitions

  • the invention relates to a double bottom plate, in particular mineral plate, furniture board and the like, with a base plate and at least one profile strip on one of its end faces, wherein the profile is made of a thermoplastically processable material.
  • the double bottom plate in the known prior art is used to create a cavity below the raised floor plate and the floor, which should allow an economical and easy installation of all necessary supply lines.
  • Such raised floors consist of individual raised floor panels, which are usually carried at their corners by mounted on the actual solid floor vertical supports, so that these raised floor panels are easy to remove, for example, after installation later in repair work from the dressing.
  • Double floor slabs are nowadays made from the materials wood, gypsum, anhydride, fiber concrete, metal, reinforced concrete as well as wood substitutes or in combinations of these materials.
  • Such double floor panels of the prior art are provided in particular on their front or narrow sides with moldings in order to protect these areas from any damage or moisture, but also to achieve certain visual effects.
  • the profile strips In order to achieve an adhesive connection between the profiled strips and the end faces of the raised floor panels, the profile strips on one of their surface adhesion promoters, which lead after appropriate activation and supply of an example hot melt adhesive system for the desired adhesive connection between the profile strip and the front side of the raised floor plate.
  • the raised floor panels which generally consist of gypsum, anhydride or fiber concrete
  • problems in the known prior art with respect to the adhesion of the applied profile strips This disadvantageously results from the fact that the adhesive system can not or not sufficiently penetrate into the material of the raised floor plate or that due to the dusty and fibrous surface of the faces of the raised floor panel no firm connection between the profile strip and the front side can be realized.
  • due to these material properties increases the reject rate and thus the production cost of such double floor panels.
  • Another disadvantage of the double bottom plates in the known prior art is that during assembly four adjoining double bottom plates are placed on a corresponding element of a vertical support.
  • the end faces of the opposing double floor panels are arranged directly adjacent to each other, so that when using the premises with raised floors in particular the footfall sound caused by movement of persons is transferred from a double floor panels to the other double floor panel in the entire room.
  • the so-called footfall sound insulation of such raised floor panels is sometimes so bad that the applicable standards for office space are not met and that, for example, raised floor panels made of metal can not be used.
  • This double bottom plate of hydraulically setting materials should be characterized in that the carrier material is bordered on two opposite sides, each with a substantially L-shaped profile, wherein the lower horizontal leg engages under the support surface of the underside of the substrate, which transversely extending sides without enclosing Leave profile while the offset and opposite profiles are each firmly connected to the substrate and the at least one probation layer is provided in the substrate.
  • the profile has on the inside an anchoring device to achieve a positive and / or non-positive connection between the profile and consisting of the hydraulically setting mass carrier plate.
  • profile frame parts can be made of aluminum, steel, plastic, ceramic or another material.
  • a disadvantage of this prior art is seen that the lower horizontal leg of the profile absorbs the entire burden of the weight of the raised floor panels themselves and by the use in premises on the vertical supports.
  • Another disadvantage is seen in the fact that, for example, in raised floor panels made of other materials, these profiles are to be subsequently connected by nailing or gluing. This results in additional expenses, with the non-positive or cohesive connection of the raised floor plate with these profiles is not guaranteed.
  • the profiles are to be mounted only on two opposite sides of the raised floor plate, so that in particular when laying raised floor panels are arranged opposite each other, which have no profile strip between them.
  • the impact sound is transmitted between the raised floor plates, in particular by the use of, for example, aluminum, steel, plastic or ceramic as materials for the moldings.
  • a raised floor panel in particular mineral board, furniture board and the like, and a profiled strip arranged on at least one of its front sides, which consists of a thermoplastic material which has constituents which at least partially have a density of approximately 0.2 g / cm 3 to about 0.85 g / cm 3 , preferably 0.4 g / cm 3 to 0.7 g / cm 3 , has the adhesive strength of the profile strip on the front side of the raised floor panel is high enough at yet significantly reduced transmission of impact sound.
  • the double floor panel according to the invention is further distinguished by the fact that the profile strip at least partially has a structured surface, which may also be formed as a microporous foam structure.
  • the structured surface which advantageously has a surface roughness of 5 to 40 microns, preferably 10 to 25 microns, a very good adhesive bond between the thermoplastically processable moldings and this opposite arranged end face of the raised floor plate is reached.
  • the differently adjustable structured surface or microporous foam structure which can be realized by various ways in the manufacturing process of the profile strip, such as chemical blowing agents (bicarbonate, sulfonhydrazide, azodicarbonamide), physical blowing agents (for example pentane, heptane) or physical foaming (for example, with Carbon dioxide), the front sides of the double floor panel according to the invention can be sealingly closed with such moldings, which meet all technical requirements and standards and are above all also economical to produce.
  • the profile strips at least partially have a bonding agent system on their surface facing the front side of the raised floor panel.
  • adhesion promoter system are selected from the group of polyolefins, the PVC copolymers and the like, wherein the primer system and an adhesive system used with the thermoplastically processable materials of the moldings can be tuned so that an optimal Verklebe42 and attractive appearance of the invention double bottom plates is feasible.
  • the attached to the front sides of the raised floor panels profile strip can also be made of a recycled thermoplastically processable material, which further positively influences the cost and efficiency of the profile strip and thus the raised floor plate.
  • a further advantage of the double bottom plate according to the invention is that the profile strip to be attached to the front side can be optimized to optimize an adhesive bond by, for example, a flame treatment, a corona discharge, a plasma treatment, but also a primer coating, so that a targeted activation of the surface of the profile strip takes place.
  • the profiled strip of a thermoplastically processable material with an elongation at break of about 3% to 80% or a tensile strength of about 40 MPa to 60 MPa also leads to an economic production of the double bottom plate according to the invention.
  • the profile strip on its side facing the front side of the raised floor plate an adhesion promoter system which is dimensioned and formulated so that the adhesive force of the adhesive bond between the profile strip and the front side of the raised floor plate is greater than the tear strength of the thermoplastically processable material of the profile strip ,
  • thermoplastically processable material profile strips in the known extrusion or coextrusion process can be produced and economically available on rolls with several hundred meters lengths, so that in the production of double floor panels invention continuous and characterized by low machine downtime manufacturing is possible.
  • the longitudinal end faces of the double floor panels according to the invention can be virtually sealed sealed, at the same time much better impact sound insulation between the adjacent arranged and separated by the profile strips mounted double bottom plates.
  • Profile strip of a polyolefin in particular of a polypropylene based on homo- and / or copolymeric polypropylene having a density of about 0.5 G / cm 3 to 0.6 g / cm 3 and a primer system based on polyurethane.
  • Double floor panel made of wood or wood substitutes.
  • Double floor slabs made of fiber concrete Double floor slabs made of fiber concrete.
  • Fig. 1 are raised bottom plates 10 recognizable, which are arranged opposite one another with their end faces 11.
  • the double bottom plate 10 is arranged at its edge region on a support element 3, which in turn is fixed on the original floor 2 of the room.
  • the double bottom plate 10 is made in this embodiment of anhydride and has on one of its end face 11, the profiled strip 4.
  • the profile strip 4 has the same width as the thickness of the double bottom plate 10.
  • the profile strip 4 is in this embodiment of the thermoplastically processable material acrylonitrile-butadiene-styrene and has a density of about 0.75 g / cm 3 .
  • the profile strip 4 is designed for the use of double bottom plates of anhydride approximately with a thickness of 1.2 mm, so that the impact sound is reduced from a bottom plate 10 to the other bottom plate 10 on the end faces 11 by the profiled strips 4 arranged there.
  • the reduction of the impact sound results from the structured surface or the microporous foam structure of the profiled strip 4 and can be dimensioned and adjusted by the thickness of the profiled strip 4 and by the density of the thermoplastic material.
  • the impact sound can be reduced by about 5 dB.
  • between the opposing double bottom plates 10 only one correspondingly sized profile strip 4 is arranged so that the double bottom plates 10 are economically producible and can be laid.
  • the profile strip 4 is over a primer system based on PVC copolymers and a correspondingly formulated hot melt adhesive on the front side 11 of the double bottom plate 10 over the entire surface, this sealing, materially fixed.
