Definitions

  • the invention relates to a laminated body for construction purposes according to the preamble of claim 1 and its use.
  • Erosion protection mats are known in which there is a loose, voluminous, needled random fiber layer, which is connected on one side with a dense, thin non-woven fabric, fabric or knitted fabric as an underlayer (DE-OS 23 21 362). After filling the spaces between the fibers in the tangled fiber layer with sand, gravel or earth, such mats are used to cover earth surfaces, e.g. Embankments. Dimensional stability of the tangled fiber layer is achieved by gluing the fibers at their crossing points. However, a granular filling is only retained by the thin underlay, so that the mat is practically open on one side so that the sand or the like can be filled in. It is therefore comparable to an open pot.
  • the sand can fall out on the open side, which means that the known mat with the filling can only be transported, if at all, with the risk of filling losses. For this reason, the mat can only be filled at its place of use, which also e.g. also because of the very crimped fibers of the tangled fiber layer with aids such as vibrating.
  • the invention is therefore based on the object of creating a generic laminate which can not only be transported without loss of filling, but also uniformly sige distribution of the granular material should enable and can be formed in any shape and / or shape.
  • the intermediate particle layer is uniformly interspersed with fibers or threads that extend through the particle layer and hold the particles in place.
  • the needling forms chambers which are delimited by the cover layer, the underlayer and the holding fibers.
  • the pressure which arises in particular as a result of the needling when the fibers of the cover layer are incorporated in the base layer, can advantageously result in the particles being retained.
  • the body can therefore be used, transported, attached in any position, ie horizontally or vertically, etc.
  • the granular particles of the building materials or constituent parts thereof according to the invention now have properties in terms of their material which actually speak against needling. It is known that sand, gravel, hydraulic binders such as lime, gypsum or cement or mixtures thereof can be present as building materials. Such granular particles may, therefore, a brittle character and / or from - have rasive properties, they can also be strongly alkaline and, for example, comprise a conventional needle punching needles upon impact indestructible strength.
  • the cover layer and the underlayer are used with conventional needling techniques, such as, for example consists of a non-woven fabric.
  • Laminated body according to claim 12 characterized in that the laminated body (1) is needled both from the cover layer (2) and from the underlay layer (3).
  • Laminated body according to one of the preceding claims, characterized in that the cover layer (2) and the underlayer (3) are needled to one another over the entire surface of the laminated body (1).
  • Laminate according to one of the preceding claims characterized in that the particles (6) are patterned, e.g. are arranged in strips, leaving particle-free locations (12) between them.
  • Laminated body according to claim 19 characterized in that the particles (6) are in particular arranged only in the depressions (8).
  • Laminate according to one of the preceding claims characterized in that at least the cover layer (2) contains textile fibers or threads, glass fibers or threads or rock wool fibers.
  • Laminate according to one of the preceding claims characterized in that a needling density of 20-200 punctures / cm2 is present.
  • Laminated bodies can thus be produced from cement, ie cement laminated bodies.
  • L IE gene in the inventive composite for example, needled fibers or filaments, that is, holding fibers or filaments before, have the cement adsorptive properties, they may bound to the hydraulic binder, and thus present in the set cement, such as the type of Moniereisens.
  • cement adsorptive fibers can be, for example, natural fibers, such as cellulose sisal or coconut fibers, polyester fibers or the like.
  • cement-incompatible fiber material so that it cannot bond to the cement when it sets. This leaves areas separated by the holding fibers or threads, corresponding to the granular particles, with hardened concrete pieces which are essentially loosely connected to one another between the adhesive holding fibers or threads.
  • adhesive fibers can e.g. Be polypropylene fibers.
  • the laminated body with the set cement then has sufficient flexibility because of the unbound fibers or threads, so that it e.g. can be rolled up as a mat.
  • the hardness and strength can also be lower in such a laminated body, so that, depending on the choice of the fiber material and / or the particle layer, a laminated body can be produced in the desired manner.
  • the laminated body according to the invention can thus be manufactured industrially, including its inner layer, and can be delivered to the place where it is needed. There, for example on a building site or on a building object, it can be used for a construction purpose accordingly and, for example, as it was delivered. It can be prepared not only for weighting and / or insulation purposes, but also with the addition of liquid to set the layer of granular particles directly at the site of the construction project for the desired construction purpose. This eliminates the need for costly warehousing or a call-up of desired bodies or body shapes, because the laminated bodies can now be supplied with a certain granular material as an inner layer, for example to a construction site and optionally used there or prepared for use.
  • the laminate as insulation, lining, manufacture of floors or ceilings or the like. can be used after it has been mixed with a liquid for setting or an appropriate binding agent.
  • a laminate for repairing industrial floors if the same is provided, for example, as a mat or with a particle layer which can cure, for example, with epoxy resins or synthetic resin mortar as a binder.
  • there is an advantageous possibility for example, of cutting off a corresponding section from a web depending on the size of the point to be repaired.
  • a laminate according to the invention as a screed substitute. If such a laminated body is in the form of a web, and the inner layer consists of a mixture of e.g. Sand and cement, such a layered body can be placed on the still moist surface of a concrete ceiling or the like, where it then connects directly to this concrete ceiling when it sets. If a laminate is provided, the top layer of which is made of a hard-wearing material, e.g. Synthetic fibers exist, so this laminate can already serve as a floor covering. In addition, it is of course still possible to apply synthetic resin to this laminated body, so that, depending on the amount of synthetic resin applied, an essentially closed surface of the floor covering results.
  • synthetic resin to this laminated body, so that, depending on the amount of synthetic resin applied, an essentially closed surface of the floor covering results.
  • an can for example, produce a mat-shaped laminate and then cut it into strips. Due to the needling of the cover layer with the underlay layer, holding fibers are also present at the cut edges transversely to the plane of the cover layer and thus prevent the granular particles from trickling out of the inner layer.
  • a laminated body according to the invention can, however, also advantageously be used to close lines, such as water pipes, power cables, etc., through wall or ceiling openings, so that in the event of a fire, through these openings, on the one hand, no smoke can pass through, and on the other hand, the fire can be broken through by one Space in the other or from one floor to the other can be prevented.
  • lines of an under heat to verformendem material such as made of thermoplastic materials
  • it is advantageous if the layer body adjacent denu g austoffen existing particles still contain particles which expand under the effect of heat and the wall or ceiling opening and then close it completely if, for example, the plastic tube has already melted.
  • Such a layered body, for example containing sand can then be hardened, for example, by means of water glass.
  • mat-like laminated bodies hardened with sand and containing sand can also be wrapped around steel girders, it also being possible for several layers of laminated bodies to be arranged one above the other.
  • this laminate keeps the heat generated during the fire directly away from this steel girder. If a steel girder surrounded by a laminate is sprayed with water when the fire brigade arrives, this steel girder can be kept cool longer.
  • a fiber and sand-containing laminate is now obtained around the beam, which means that the water is in larger quantities on the Surface of the steel beam can remain.
  • a laminated body according to the invention is advantageously suitable for the quick, cheap construction of makeshift huts, e.g. in disaster areas.
  • Mat or sheet-shaped laminate bodies which are at least connected to one another can be placed over a carrier skeleton.
  • the carrier skeleton can also be produced from laminates according to the invention, which e.g. contain a binder in addition to sand and then, if necessary, hardened around molded iron.
  • loam, clay or the like can also be applied to the mat-shaped laminate.
  • the backing layer of the laminated body according to the invention can be made of a fiber-free material, e.g. a film such as plastic film, e.g. are made of polyethylene or polypropylene.
  • this underlayer can also be formed from a spun bond or a nonwoven fabric.
  • the cover layer is advantageously a fiber or filament nonwoven that can itself be actively needled.
  • the holding fibers or threads used in needling then advantageously come from this cover layer.
  • the layer contains actively needles Layer, for example, long fibers with a stack length of preferably 60-150 mm.
  • the layers are preferably needled together over the entire length of the layered body, so that a needling density of approximately 20-200 punctures / cm 2 is present.
  • the base layer can have depressions which are cup-shaped or elongated. These depressions are filled with the particles, these particles preferably lying only in the depressions. It is then e.g. a mat in front of which the cup-like depressions protrude like knobs. These knobs can either be used as a non-slip back, whereby they advantageously grip the base layer, such as the underlying ground or the like, if you use such a mat e.g. used as a walking mat or the like, or you can also use the knobs upwards as an anti-slip, e.g. use a walk-on surface.
  • the particles present in the depressions can be unbound or e.g. after adding water beforehand.
  • Such a mat can still be bent around the webs present between the depressions, e.g. can also be rolled up, sections can also advantageously be cut off from a rolled-up mat.
  • the result is e.g. a rollable concrete mat that can also be divided as "concrete by the meter”.
  • Laminates provided with the particle material can be used as concrete or cement fleece, as a reinforcement layer, floor covering, wall coverings or the like. However, it is also possible, for example, to moisten the needled laminate and to convert it into another desired, for example corrugated form or the like in the moist form.
  • the laminated body according to the invention if it is, for example, in the form of a mat, a layer can be produced which isolates at the same time has the and soundproofing character.
  • the layer thickness can of course be increased by laying the mats on top of one another. Such mats can rest on their own weight, so that gluing to the underlay can be omitted.
  • the layered body Due to the fiber or thread-containing cover layer, the layered body has, for example, a surface that takes away the appearance of a hardened concrete or cement body.
  • the fibers themselves can also be colored so that colored laminated bodies can be produced.
  • the fibers e.g. in concrete, e.g. To be able to glue facade panels better on the concrete surface. But you can also nail a wooden structure to the mat and place plaster or spray on it, or, if the laminate itself contains a plaster mixture, form it as a plaster layer. This advantageously avoids cracks and warping.
  • the mats can also be used as wallpaper at the same time. Due to the construction of the laminated body according to the invention, holes or slots can be cut into it without tearing open further. If, for example, thermoplastic fibers are used in the cover layer, such holes can also be welded through the laminate, the thermoplastic fibers being welded into the hole walls. As a result, such holes are also watertight. As a result of its structure, the laminated body according to the invention is also flame-retardant, which can be reinforced by using appropriate fiber material.
  • the particles can also have a grain size of 30 mm, those with a grain size of 0.02-2 mm are preferably used, which then have a basis weight of e.g. 4 - 12 kg / m2 are available.

  • felting needles with a triangular needle shaft and lateral barbs directed towards the tip are most commonly used for needling. Other shapes are also common, such as fork needles or loop needles.
  • the sewing needles mentioned in the aforementioned book can also be used accordingly for needling the laminated body.
  • the felting needles grasp individual or tufts of fibers 4 from this fiber layer and interweave them with the underlay layer 3.
  • the fiber layer 2 must be actively needled, ie fibers should be able to be detected from this layer, a portion of these fibers 4 still being anchored in layer 2.
  • the needling process not only connects the two layers 2 and 3 to one another, it also prevents the granular particles 6 of the layer 5 from shifting laterally by the holding fibers 4 which are distributed throughout the entire surface of the layer body 1. This makes it possible to cut the laminate into any shape without the rock particles dropping out of the cut edge in significant quantities.
  • the sheet-like body 1 produced in sheet form can also be divided into individual, commercially available sizes by means of separation welding. If thermoplastic fibers are used, the edges of the individual pieces can also be solidified by welding. If necessary, a strip of thermoplastic material, not shown, is welded in a U-shape under the action of pressure and heat in the region of the edge, as a result of which the laminated body 1 is given a more pleasing appearance.
