Definitions

  • the invention relates to wood-concrete composite systems, which consist of wooden components, intermediate layers and concrete components according to the features of the preamble of claim 1.
  • the known connecting element is formed as a flat flat body in the form of a steel sheet which is glued into a slot introduced in the wood so that it protrudes over a part of its surface from the wood.
  • the protruding part of the connecting element is used for connection to another material.
  • the known connecting element is formed as a flat flat body in the form of a steel sheet which is glued into a slot introduced in the wood so that it protrudes over a part of its surface from the wood.
  • the protruding part of the connecting element has anchor tongues which anchor in the cast-on concrete.
  • a wood-concrete composite element which consists of a plurality of assembled boards, which in turn comprise composite webs and an overlying concrete component.
  • the bond between the concrete component and the boards or composite webs is created by - inserted in the wood recesses - embarked transverse force anchors.
  • the transverse force anchors are arranged transversely to the longitudinal direction of the composite boards and thus have a geometric toothing between wood and concrete. See also DE 202 10 714 U1 ,
  • a major disadvantage of the aforementioned writings is the lack of final coupling of the materials wood and concrete and the resulting limitations in the application. So it is known that a direct contact between Wood and concrete can lead to condensation and thus mold in the wood. Furthermore, in a direct contact between wood and concrete creates a sound bridge, which prevents the usability of a wood-concrete composite ceiling without further construction. Furthermore, it is known that the stiffness of a cross-section increases with increasing lever arm and thus leads to a pronounced interlayer formation to stiffer systems.
  • the object of the invention is to provide wood-concrete composite systems with intermediate layers, which are equipped with high bonding forces, different cross-sectional variants, different system properties and different physical properties.
  • the task of the intermediate layer is to create a decoupling of the significantly different materials wood and concrete, without reducing the stiff or rigid connection - a prerequisite for an effective composite effect - of the two materials.
  • the present invention describes a wood-concrete composite system consisting of wooden components, intermediate layers and concrete components.
  • the wooden components are connected to the concrete component quasi rigidly by continuously arranged connection means.
  • the connecting means are formed as a flat body with corresponding openings or roughening, as a grid and / or as networks of metals and / or plastics. At least one end of the connecting means is positively connected by gluing with the wooden components. It has surprisingly been found that the bonding of two ends of the connecting means with the wood components not only produces an increase in intrinsic stability, but also provides an increase in the composite stiffness. It may be expedient to form the fasteners inhomogeneous and anisotropic, so that from this different properties (of the connecting element) in the different materials (wood component, intermediate layer, concrete component) result.
  • the shape of the fasteners is in addition to the straight shape in all other odd shapes, such as curved, wavy, kinked, angled and / or just conceivable and will depend only on the application requirements.
  • the arrangements of the connecting elements in the composite system according to the invention can, for example, run side by side, one behind the other, diagonally, offset, offset, undulating and / or chaotic and are only dependent on the application requirements.
  • the connecting means are anchored in the wooden components by gluing at least one end in prepared slots or depressions and in the concrete component by mechanical gearing in the set cement glue.
  • Another embodiment lies e.g. to glue therein the connecting means on the wooden components or partly in and partly on the wooden components, thereby producing a permanent and non-positive connection.
  • the connecting means penetrate the intermediate layers as required, partially or without a frictional connection with the intermediate layers.
  • the intermediate layers at least partially decouple the wooden components from the concrete components, thereby allowing a durable composite solution.
  • the wood components have at least in some applications reinforcements, which bridge the structural and manufacturing weaknesses of the wood and / or wood-based materials and wood composites. It is also conceivable in some applications to increase the capacity of the timber components by reinforcement or reinforcements, thereby generating an increase in the total capacity.
  • the concrete components have, on the one hand, deposits which bridge the structural weak points of the concrete and / or, on the other, deposits which change the structural-physical conditions of the wood-concrete composite system.
  • the intermediate layers are at least partially given as geometrical, mechanical, structural-physical and / or structural separation or end coupling between the timber components and concrete components.
  • the intermediate layers of the wood-concrete composite system can be formed as single-layer or multi-layer layers.
  • the intermediate layers can be consumed and / or incorporated in liquid, solid and / or gaseous form, for example by laying, pouring, brushing and / or foaming.
  • a single-layer intermediate layer consists for example of a plastic film, impregnated paper, bitumen, Kunststoffdämm Mrs, mineral insulation layer, organic insulation, renewable insulation material and cast-on or painted materials that set or harden at a later date, such as tar, adhesives, plastic mixtures.
  • Other forms of single-layer intermediate layers represent all mineral or mineral-bonded materials (eg mineral-bonded lightweight board, mineral-bound and insulated leveling screed) and metallic materials (eg trapezoidal sheets, sandwich components).
  • the multilayer levels are a combination of the previously described single-layer intermediate layers in any Shape and / or arrangement. The choice of the single-layer or multi-layer intermediate layers is therefore only dependent on the requirements of the wood-concrete composite systems.
  • An advantage of the invention is the decoupling of the facing surfaces of the wooden components and the concrete components by the embedded intermediate layer or intermediate layers.
  • building components in the concrete components can be kept away from the timber components. Wetting of the wooden components would permanently cause rot and thus destruction of the entire wood-concrete composite systems. This is especially given in bridge construction.
  • intermediate layers at least in some applications, have cavities, such as e.g. Cables, pipes, hoses, ducts and conduits, e.g. Power, gas, water, air conditioning, electrical installation lines, which are used for coupling to central systems.
  • cavities such as e.g. Cables, pipes, hoses, ducts and conduits, e.g. Power, gas, water, air conditioning, electrical installation lines, which are used for coupling to central systems.
  • corresponding supply lines can be embedded in the "stress-neutral" intermediate layers.
  • Another advantage lies in the thermal decoupling of the facing surfaces of the wooden components and the concrete components by the embedded intermediate layers.
  • This process can be prevented by the arrangement of intermediate layers such as mineral insulation in conjunction with overlying foil.
  • intermediate layers such as mineral insulation in conjunction with overlying foil.
  • wood-concrete composite systems according to the invention provide an advantageous solution.
  • Another advantage lies in the physical decoupling of the facing surfaces of the timber components and the concrete components by the embedded intermediate layers.
  • additional "floating screed” arranged for impact sound insulation on the composite ceiling.
  • an intermediate layer in the form of impact sound insulation it is possible to improve the sound insulation of the wood-concrete composite system according to the invention and thus to produce a surface decoupling between the concrete components and the timber components.
  • this can be dispensed with in many applications on a "floating screed".
  • Another advantage lies in the increase of the "inner lever arm" of the wood-concrete composite system according to the invention by increasing the distance between the bending pressure and bending tension zone.
  • a solution according to the invention in the form of a box cross-section in conjunction with an intermediate layer produces an incomparable rigidity of the wood-concrete composite system.
  • wide-span supporting systems for example roofs, ceilings, bridges
  • Another advantage lies in the bonding of two or more ends of the connecting means with the wooden components. As a result, not only the inherent rigidity of the connecting means but also the composite stiffness between the timber components and concrete components is increased. Only then can be used according to the invention connecting means in an economical manner.
  • Another advantage of the invention lies in the quasi-continuous connection between the timber components and concrete components of the wood-concrete composite system.
  • single-field systems i.e., systems that protrude above a span.
  • continuous systems are not only more economical but also more efficient than single-field systems.
  • Another advantage is the at least partial bridging of structural vulnerabilities, such as e.g. Branches, inclusions, growth defects of the wood, which lead in the application to a limitation of the entire wood-concrete composite system.
  • Another advantage is the at least partial bridging of manufacturing vulnerability, such as Finger jointing, openings, holes, which lead in the application to a limitation of the entire wood-concrete composite system.
  • the wood-concrete composite system consists of wooden components and at least one adjacent concrete components characterized in that at least partially and at least a single-layer intermediate layer is formed between the wood components and concrete components, which at least partially generates a separation or decoupling of the materials wood and concrete.
  • the task of the intermediate layers is thus at least partially to produce a geometric, mechanical and / or structural-physical decoupling of the materials wood and concrete.
  • this decoupling must not significantly reduce the composite effect between wood and concrete, otherwise an economical solution can not be achieved.
  • connecting elements with the intermediate layer or the intermediate layers.
  • the connecting means have no bond to the intermediate layers.
  • inventive composite system wherein the connecting elements are adhesively bonded to the concrete components.
  • the connecting means can be ordered and / or chaotically arranged depending on the application.
  • the term "chaotic” is here partly taken from mathematics and means not ordered or not bound to rules. By way of example, the following are named as an arrangement: one behind the other, side by side, offset, longitudinal, transverse, diagonal, wavy, curved and / or scattered.
  • the fasteners are used as flat bodies, meshes and / or nets in straight and / or odd shape of metals and / or plastics.
  • the connecting elements may be formed at least partially straight, curved, wavy, curved, kinked, bent and / or twisted.
  • the flat bodies can be at least partially perforated, punched, drilled, roughened, stretched, pulled and / or distorted.
  • An embodiment of the wood-concrete composite systems according to the invention has, for example, the plastic part to be anchored in the wood and the metal part to be anchored in the concrete.
  • the connecting element would be referred to as hybrid material (metal and plastic).
  • an anisotropic and inhomogeneous design of the connecting elements is selected depending on the application.
  • a further embodiment consists in the bonding of two or more ends of the connecting elements according to the invention in and / or on the wooden components.
  • a further embodiment of the invention consists in providing additional toothings, elevations and / or beads at least in partial regions of the connecting elements. Surprisingly, this has shown that thereby a positioning and / or fixing of the connecting elements in the corresponding openings of the wooden components to ensure ligation of the adhesive. Furthermore, the leakage of the adhesive is prevented until setting. Thus, the fasteners can be glued in the factory and transport even before the setting of the adhesive, temporarily store and / or assemble. This is also possible for wall or overhead applications.
  • the connecting means are fixed by gluing in corresponding openings in the wooden components and / or on the wooden components. It is thus an embodiment of the invention conceivable to be glued in the fasteners in the timber components and others are glued to the wood components.
  • the bond is preferably produced by one- or two-component adhesives. Some adhesives (e.g., epoxy resins, poly-urethane adhesives) are affected by the glass transition effect under conditions of stress and climatic conditions. The glass transition effect describes a phenomenon in which the adhesive loses its strength at the same temperature and load.
  • One embodiment of the application according to the invention is an energy supply of the adhesive joint of the connecting elements and / or the adjacent components during bonding or at a later time, thereby increasing the glass transition effect to a higher temperature level and thereby increase or secure the composite effect.
  • the energy supply may be initiated locally and / or areal by way of example by a stationary or mobile heat source (for example infrared). It is also conceivable to ensure the supply of heat by cable guides, which are located in the timber components, the intermediate layers and / or the concrete components.

  • the lines 214 are used for indirect heating of the dacarbit, thereby increasing the material-related glass transition temperature of the adhesive and thereby increase the carrying capacity of the kauselementverklebung under the influence of temperature.
  • the connecting elements 220 are here exemplified as corrugated dimensionally stable plastic mesh 221 and formed as a bent metal mesh 223 .
  • the metal meshes 223 are used by way of example in a partial area of the wood-concrete composite system in that high local stresses prevail.
  • the plastic grids 221 are anchored at about one-third of their height, with one end in the wooden member 210 by gluing.
  • the plastic grids 221 have been made such that the grid openings 222 in the wood material 210 and in the intermediate layers 230 have smaller dimensions (close-meshed) than in the concrete component 240, thereby saving on adhesive in the anchoring in the wooden component (lower adhesive volume) and on the other to increase the intrinsic stability of the plastic grids 221 in the region of the intermediate layers 230 (no frictional lateral support).
  • the undulating shape provides, on the one hand additional inherent stability and on the other hand a further mechanical interlocking between the wooden components and concrete components to be joined.
  • the plastic grids 221 have in the binding region of the wooden components 210 teeth (not shown here), which ensure a mechanical fixation of the connecting elements to the setting of the adhesive.
  • the metal grid 223 are glued here, for example, with two ends in corresponding openings (here slots or channels) of the wooden components and thereby provide in itself a geometrically rigid shape and at the same time a very rigid connection between the timber members 210 and the concrete components 240.
  • the metal mesh 223 have in the kerf between connecting element and wood, for example, a bead (not shown here), which prevents the adhesive from exiting.
  • the intermediate layers 230 consist here by way of example of a multilayer bitumen coating with embedded plastic film 231 and a PU rigid foam layer 232, which was created by way of example from individually cut and laid in association panels.
  • the concrete components 240 are formed here by way of example by a constant plate 241 .
  • the concrete components 240 have reinforcements 242 in the form of welded steel meshes 243 , which for example only rest on the connecting elements 220 .
  • the concrete slab 241 further includes a localized reinforcement 244 in the form of a reinforcing steel 245 which has been laterally connected (for example, wire-knurled, not shown) prior to concreting and applying the welded steel mat 243 to the securing member 220 .
  • the concrete components 240 furthermore have cavities 246 and lines 247 , which serve, on the one hand, for subsequent reinforcement and, on the other hand, for the climatic supply of the concrete components 240 .
  • the cavities 246 are used to introduce appropriate prestressing steels in order to enable a non-positive subsequent reinforcement of the concrete components 240 .
  • the position of the cavities 246 is dependent on the execution requirements and can be exemplified by, between and / or through the connectors 220 and / or 223 .
  • the lines 247 serve as an example - via a coupling with a corresponding climate control center - for the climatic supply of the wood-concrete composite system and its surroundings.
  • the wood-concrete composite system 200 was here prefabricated as an example in the factory as a precast and delivered as individual components Segmented to the site and mounted. Such prefabrication allows rapid construction of the structure without introducing additional moisture (eg mixing water of the reinforced concrete) in the wood-concrete composite system or buildings.
  • the individual wood-concrete composite systems can be connected to the construction site immediately during assembly or some time later with each other and / or with other construction sections non-positively and / or positively. In this way, disc effects with segmented wood-concrete composite systems can be produced.
