Definitions

  • the invention relates to a drainage, sealing and / or Thermal insulation board according to the preamble of claim 1.
  • an insulating plate which both for thermal insulation and for the Water drainage should serve.
  • the plate has a variety of open drainage channels on a plate surface. These drainage channels extend from the first edge to the opposite second edge, the channels are open on both edges of the plate.
  • a connecting channel arranged along the extends first and second plate edge and in connection stands with each drainage channel and is perpendicular to these extends.
  • Each of the connection channels is in the direction of Plate thickness offset relative to the drainage channels and in one side wall a plurality of openings as a passage available for every drainage channel.
  • Drainage channels on the plate surface with a sheet-like material covered so that the drainage channels are protected against the ingress of particles.
  • a blatant disadvantage of the known plates from the state The technology is that after a short time Operating time, i.e. after only a few weeks after the Plates are mounted, not a satisfactory one There is more fluid drainage.
  • a plate according to EP 0 127 824 brings significant disadvantages.
  • the filter fleece is not absolutely particle-blocking acts. Mud that penetrates the fleece can build up in the Inside, i.e. place behind the filter fleece. Especially in this sludge cannot connect horizontally are removed and clogged with time, so that here the drainage effect is completely lost. For this also contributes to the multiple redirection of the water supply, where there are always deposits at the deflection points begin.
  • the invention is based on the further finding that with the currently commercially available records, which the Fleece covering drainage channels, due to the earth pressure in the Channels are pushed in and blocked or at least reduced in the discharge cross-section, so that this also the drainage effect is lost.
  • EP-A-0 100 231 discloses a drainage, sealing and / or Thermal insulation board for the external cladding of walls in contact with the earth, on their liquid-permeable and particle-blocking material has covered drainage channels.
  • the drainage seal and / or Thermal insulation board is a composite board with the liquid-permeable and particle-blocking material formed, and the cross-sectional shape of the drainage channels and their course over the longitudinal axis of the channel and the arrangement and positioning the drainage channels relative to one another and relative to the plate are chosen so that the arrangement in the composite on the outer wall of the building as a closed drainage seal and / or Thermal insulation layer for the purpose of unimpeded Liquid drainage a direct communication of the Drainage channels of adjacent plates are present.
  • the Drainage channels are with at least one end Provide expansion.
  • EP-A-0 100 231 discloses no indication of the problem of lack of communication the drainage channels of adjacent plates. For plates with particle-blocking fleece can be because of the missing Visibility of the drainage channels, especially on the construction site not pay attention to how the drainage channels adjacent plates are arranged relative to each other.
  • the EP-A-0 100 231 also does not disclose any reference to this Problem of economical production of the plates with Drainage channels. According to the disclosure of EP-A-0 100 231 are the drainage channels of adjacent plates when the Disconnected plates and water can then flow through the Do not drain drainage channels. Offset when assembling Slabs often result on the construction site and especially if the drainage channels with a particle fleece are covered regularly. With neighboring plates of EP-A-0 100 231, drainage is therefore generally not possible.
  • the present invention is therefore the object based on a combined heat insulation and sealing To create drainage plate by means of a closed Thermal insulation, sealing and drainage layer formed can be, with each offset of the plates one Communication of the drainage channels from one plate to the other another disk.
  • this object is achieved by a drainage, Sealing and heat insulating plate with the characteristics of Claim 1 solved.
  • the invention is also based on the object to derive from Landfill waters to be used, also an approximate vertical placement of the plate is sought.
  • the thermal insulation, sealing and Drainage plate is on the outer wall from touching the ground Attached to walls. These plates have on their side drainage channels away from the wall from a permeable to water, but acting as a particle barrier Material are covered.
  • the Drainage channels both a cross-sectional shape and one Course over the longitudinal axis of the channel, which next to her Arrangement and positioning to each other is chosen so that when arranged as a composite on the outside wall of the building closed heat, sealing and drainage layer, for the purpose direct unimpeded drainage Communication of the drainage channels of neighboring plates is present.
  • This embodiment of the invention is for use on buildings designed.
  • the same plate can also, for example used to drain leachate from landfills only drainage and sealing tasks are fulfilled. The thermal insulation properties can then of course be neglected.
  • the drainage channels themselves are through in the Grooves formed on the plate surface of the side remote from the wall formed in the course of the molding process without subsequent machining and material removal are incorporated.
  • the channels are on at least one Open at the end. It is important that they are on their outer surface at least with an inlet opening for receiving the liquid to be discharged are provided.
  • This Inlet opening can be through a in the plate opening Channel leading breakthrough that is approximately across the entire channel length or through perforations be formed.
  • Incorporate or open perforation in the plate body a plate provided with open drainage channels as put on separate layer.
  • the entire drainage plate is made from one rot-proof, expandable particle foam created, the final plate shape in the course of Shaping process in a corresponding device is formed.
  • the base material of the plates consists of a pre-expanded expandable particulate material, which in a form that a spatial closure against the Environment forms, and against the resulting expansion pressure is resistant, one initiated into the form and the Exposure medium is exposed such that an evenly closed and condensed on all sides Surface results.
  • the channel width of the drainage channels is larger than the width of the between separators remaining in the drainage channels. It exists but also the possibility to leave this relationship and the drainage channels at their marginal outlets, where they correspond to the neighboring plates, to be provided with widenings. With one particularly preferred embodiment of the present invention these widenings of funnel shape.
  • the drainage channels are preferably related aligned vertically to the mounting position. It exists but also the possibility of diagonal drainage channels, to cross each other, either on the Groove / land ratio used as suggested will, or also here at the spouts widenings be provided.
  • the diagonally arranged drainage channels are from im essential square dividers limited.
  • the surface of the profiles on the circumference of the plates is preferably slightly less than half the surface the square dividers.
  • Drainage channels for the purpose of forming an adequate Support surface for the water permeable and Particle-blocking covering material on the plate surface to form the side far from the wall relatively narrow and Plate core aligned, the drainage correspondence to provide appropriate widening.
  • the drainage plates which are made of foamed plastic, as stated rot.
  • a filter fleece known per se is used, this in the course of the shaping process on the plate body with or without adhesion promoter through thermal fusion is applied and connected so that the drainage plate is designed as a composite panel.
  • liquid-permeable, Particle-blocking material as a foam sheet is provided, which is a relatively large Space between the foam balls, a so-called large gusset volume.
  • the filter fleece to be replaced by a grid that is inherently rigid Shape is. If such is not sufficient inherently rigid property, there is the possibility between the filter fleece or the one used particle-blocking material and the plate body one to arrange inherently rigid material layer that of course, also more permeable to liquids and must be of a particle-blocking type, and preferably is porous in shape.
  • one is for adaptation in the panel assembly Step fold training provided, for example by the side away from the wall with a slope against the plate core is formed, at the end of the slope of about In the middle of the plate a vertically running paragraph in one second slope against the wall.
  • the plate is on the back with an additional sealing layer.
  • This can both over the entire surface and only at the edges be arranged in such a way that the sealing layer on the edge, extends overlapping in the composite such that all butt joints that form with additional Sealing material is stored.
  • the present invention provides an insulation board created which, as a combination, the function of Combine thermal insulation, sealing and drainage and preferably in the area of components in contact with the ground place. According to the present invention, this can proposed system also in the area of landfills and the like are used in which leachate in Vertical range is to be caught.
  • the plate is created as a one-piece structure and leaves produce without machining post-processing.
  • a particularly dense one Edge formation is achieved that one above the other arranged drainage plates laterally offset from each other can be, and the drainage channels that follow the water dissipate below, still communicate with each other, i.e. in Connect and the water on the The top of the plate can flow off.
  • To drain large Amounts of liquid are required for a given Filter permeability the groove width and thus the to enlarge the available filter area.
  • the groove width is limited by the prevailing earth pressure of the accumulated material in front of the filter surface, the with increasing installation depth becomes larger (up to 40 KN per sqm and more) and the traffic loads occurring in the immediate vicinity. Due to both stresses, earth pressure and traffic loads, the dividers are compressed and the discharge cross-section shrinks permanently. So that would Drainage performance decrease. According to the invention, this was Disadvantages effectively counteracted.
  • this filter fleece press into the grooves so that the Drainage cross-section and thus the drainage capacity reduced.
  • Figure 1 shows an example of use of the present Invention for parts of the building touching the ground.
  • a Outer wall 2 of the building here a basement wall, is, as usual, with a primer 11 before one Bitumen top coating 19 is applied.
