- Component in particular plate-shaped component made of concrete and concrete aggregate material
- unreinforced concrete components e.g. in slab, column or tube form, known to consist of cement and concrete aggregate material. It is also known columnar, tubular or plate-shaped reinforcing steel components with integrated welded steel mesh consisting of reinforcing bar steel in the diameter range of 6 mm to e.g. 50 mm or consist of so-called reinforcing wire in the diameter range of 4 mm to 12 mm.
- the invention has for its object to provide a comparison with the known concrete components improved component, especially with extended applications.
- a component of a layer of cement and concrete aggregate material in which a reinforcing mat is embedded, the at least two fabric layers with wire thicknesses in the range of about 0.5 mm to 3.5 mm and mesh sizes in the range of about 2 mm 60 mm, characterized in that it has at least one second layer of castable, curable or abrivssentem material.
- a mechanical anchoring between the two layers is provided by the reinforcing mat with the micro-fabric layers distributed over its surface contains substantially perpendicular and / or obliquely to the reinforcing mat surface aligned anchoring elements which protrude from the micro-reinforced layer in the other layer. This gives a multilayer component which has a complete bond at the layer transitions.
- Another idea of the invention is to combine or assemble a concrete element forming a first layer, which has a micro-reinforcement, with a second layer such that at least one micro-fabric layer of the first layer is integrated into the second layer both layers are preferably connected to one another by additional anchoring elements, which are aligned substantially perpendicularly and / or obliquely to the component surface, wherein at least one micro-fabric layer of the first layer is embedded in the second layer, as can be seen from a common consideration of claims 1, 2 and 8 results.
- the invention relates to such components in which the micro-reinforced element is combined in particular with another reinforced or unreinforced concrete element or a component of other building materials, for example from other hydraulically bound Materials such as gypsum, or from mastic asphalt, plastics, such as acrylates (acrylic glass) and the like.
- the device treated in claims 21 and 22 is a commercially viable element for producing a component according to claims 1 to 20 and for carrying out the method according to claims 23 and 24.
- two variants are proposed according to the invention, namely the production of a plate-shaped concrete component with a reinforcement mat of several micro-fabric layers, which are fixed or positioned by anchoring elements which are integrated into the reinforcing mat and protrude beyond the reinforcement mat one sheds the mixture of cement and concrete aggregate including water only over a portion of the reinforcing mat thickness, and that one either
- FIG. 1 shows a schematic representation of a reinforcement mat made up of a plurality of superimposed micro-fabric layers
- Figure 2 shows a schematic representation of the reinforcement mat integrated into a
- Figure 3 shows a schematic representation of the finished plate-shaped component consisting of a lower "micro-reinforced" concrete layer (A) and an overlying reinforced or unreinforced concrete layer (B),
- Figures 4 to 6 show representations corresponding to Figures 1 to 3 with at least one upper wavy fabric layer;
- Figure 7 shows a schematic representation of a reinforcement mat of several
- Figure 8 shows a schematic representation of a combined plate-shaped component with an upper reinforced concrete layer
- FIG. 9 shows a sectional view of the reinforced concrete support with outer micro-reinforced casing shown in FIG.
- Figure 1 shows a schematic representation of a reinforcing mat 1, which consists of several stacked fabric layers 2 with wire thicknesses in the range of about 0.5 mm to 3.5 mm and with mesh sizes in the range of about 2 mm to 60 mm and as a "micro-fabric layer
- the micro-fabric layers 2 are preferably made of steel or of plastic, such as polyamide fibers, aramids, carbon materials, glass fibers and / or textiles.
- These micro-fabric layers 2 are positioned and fixed by anchoring elements 3, which also have their upper ends above the reinforcing mat 1.
- These anchoring elements 3 are preferably made of wires which are angled or hook-shaped at their upper, exposed ends or also of helical members According to FIG. 7, also band-shaped anchoring elements 3a and / or wavy anchoring elements 3b can be used.
- Between adjacent micro-fabric layers 2 D can lancing body 12 may be arranged.
- FIG. 2 shows a concrete base plate 4 forming a layer A, in which the concrete mixture consisting of cement, concrete aggregate material and water is infiltrated over only a part of the reinforcing mat thickness so that, for example, two micro-fabric layers 2 are also above the concrete base plate 4.
- Figure 3 shows a plate-shaped component consisting of a micro-reinforced base plate 4, which forms a layer A, and an upper, unreinforced concrete layer B, wherein due to the lying above the base plate 1 upper fabric layers 2, the transition between the two layers A and B is flowing ie it has created a full network.
- Figures 4 to 6 substantially correspond to the representations of Figures 1 to 3, in which case, however, the upper micro-fabric layer has 2.1 waveform.
- Figure 8 shows a schematic representation of a two-layer slab with a lower concrete base plate 4 and an upper concrete slab 5, which is reinforced or reinforced with reinforcing bar elements 6.
- Differently designed anchoring elements 7, 7 'and 8 are about the reinforcing mat surface distributed and are substantially perpendicular and / or obliquely thereto.
- the wire-shaped anchoring element 7 shown in FIG. 8 has an angled portion 7.1 at its end located in the micro-reinforced base plate 4.
- the upper end 7.2 is helical or helical designed.
- This anchoring element 7 is shown once aligned substantially perpendicular to the two-layer plate and on the other obliquely as anchoring element T ', 7.1' and 7.2 'to the two-layer plate.
- the anchoring element 8 which is furthermore shown by way of example in FIG. 8, has a bend 8.1 at its lower end and essentially the shape of a hook 8.2 embracing the reinforcing steel bar 6 at its upper end.
- the reinforcing bars 6 have a diameter in the range of about 6 mm to 50 mm.
- the reinforcement or reinforcement of the upper concrete slab 5 can also have a reinforcing mat made of reinforcing wire in the diameter range of 4 mm to 12 mm.
- the fabric layers 2 of the micro-reinforcement mat 1 can be designed and arranged so that over the reinforcement mat thickness there is a change in the mesh or hole widths of the fabric layers, such that in the production of the concrete base plate 4 during cement mortar or Betoninf ⁇ ltration concrete aggregate body of different size over the reinforcement mat thickness are sorted according to their size or distributed in a targeted manner.
- This sieving effect can be achieved by varying the mesh size and / or by offsetting layers of layers 2 layered on top of each other, each of which has the same mesh size.
- the fabric layers 2 of the reinforcing mat 1 can also have the same structure in terms of dimensions and be arranged congruently one above the other.
- thicknesses of the layer A and the layer B can be varied widely.
- the component can also have the form of a column 9 with a reinforced concrete core 6 reinforced with reinforcing bar steel 6, which is surrounded by a concrete layer 11 with micro-reinforcement.
- the component according to the invention may also have the shape of a pipe with a reinforced concrete cylinder or rectangle, for example, which carries a micro-reinforced concrete layer inside and / or outside.
- the invention also relates to the plate-shaped component shown by itself in FIGS. 2 and 5, consisting of a concrete base plate 4 into which a reinforcing mat of a plurality of micro-fabric layers of the type described above is embedded.
- This prefabricated component can be installed on site and subsequently cast with an unreinforced concrete layer or a reinforced concrete layer B.
- the inventive method for producing a plate-shaped component consists in that one uses a reinforcing mat 1 with at least two layers of fabric 2, by anchoring elements 3, which are integrated into the reinforcing mat and the reinforcement mat are projected, fixed and positioned so that one infiltrates a mixture of cement, concrete aggregate material and water in a layer thickness which makes up only a portion of the reinforcing mat thickness, and that before setting this mixture above the mixture layer with not yet hardened cement a layer made of unreinforced concrete or reinforced concrete as a fresh-fresh grout.
- reinforcing mat 1 it is preferably also possible, above the reinforcing mat 1 to attach a welded steel mat before pouring the mixture in the layered reinforcing mat 1 and welded mesh mat.
