Definitions

  • the invention relates to a composite wall construction for a building.
  • wall constructions must meet different requirements in terms of building physics, and for example guarantee certain load-bearing capacity values or thermal conductivity values.
  • a composite component for a building by the applicant, which has a thermal barrier coating, is in the older German patent application DE 10 2016 120 947 A1 the applicant described.
  • This publication discloses a composite wall which has two wall layers and an intermediate thermal insulation layer, where it is proposed to accommodate a reinforcement textile arrangement in the insulation layer in order to be able to transmit tensile forces between the two wall layers.
  • the present invention does not relate to composite wall structures that have an insulating layer, but to a composite wall structure that can achieve a high load-bearing capacity.
  • the composite wall construction should be as simple as possible to manufacture, also allow production as a finished part, and be designed to be transportable as a finished part in a simple manner.
  • the principle of the invention is essentially to provide a composite wall construction for a building, which has a textile concrete layer and a wall layer of stone elements.
  • the wall layer consists of a large number of stone elements.
  • the stone elements can be made from natural stone, from artificial stone or from a suitable other stone or stone-like material.
  • the stone elements are provided by masonry stones, in particular by bricks, sand-lime bricks or other masonry stones, in particular block stones.
  • the wall layer can also be provided from plate-shaped stone elements, such as straps, ceramic plates, stone plates or the like.
  • the individual stone elements are connected to each other by a connecting means such as mortar or grout.
  • the first wall layer is therefore provided by masonry or alternatively by a stone slab wall layer.
  • the wall layer runs along a flat surface, and in an alternative of the invention, along a curved surface.
  • a curved surface can take any spatial shape.
  • a curved surface in the sense of the invention can also have flat and curved sections.
  • the second essential layer of the composite wall construction is a textile concrete layer.
  • the textile concrete layer comprises a textile reinforcement, which is bordered on both sides by concrete.
  • the textile concrete layer thus comprises a first concrete layer, a second concrete layer, and a textile reinforcement in between.
  • the textile reinforcement consists of suitable reinforcing fibers, for example, a scrim made of carbon, glass, basalt, ceramic or aramid fibers.
  • textile refers to technical textiles.
  • alkali-resistant glass fibers and carbon fibers come into consideration as fiber materials.
  • suitable reinforcing fibers are used, which - in contrast to the steel reinforcement in reinforced concrete - do not corrode.
  • the textile fabric can consist of yarns which are composed of continuous fibers, the so-called filaments. These continuous fibers are processed on textile machines to form a lattice-like structure.
  • the textile reinforcement extends along the surface along which the wall layer extends. In other words, the textile reinforcement runs parallel to the wall layer.
  • the textile reinforcement is also aligned along the same plane. If, in an alternative of the invention, the wall layer is aligned along a curved surface, the textile reinforcement is also aligned along the same curved surface - and thus parallel to the surface - to the wall layer.
  • the textile reinforcement runs along the entire surface along which the wall layer extends. This means that reinforcing fibers extend along the dimensions of the textile-concrete layer at least into all edge regions of the textile-concrete layer, or may also protrude beyond them.
  • the dimensions of the textile reinforcements are therefore at least as large as the dimensions of the wall layer, and possibly also - at least slightly - larger.
  • the invention also includes when protruding areas of the textile reinforcement protrude or protrude outwards from the textile concrete layer on one side, on several sides or on all sides.
  • the textile reinforcement can be made from a single piece, or from several sections, which are particularly connected to one another, for example sewn together, woven together or glued to one another, or are connected to one another in another way while ensuring the transmission of tensile forces.
  • the invention also encompasses if the textile reinforcement consists of several sections which run continuously except for slight spacing areas or up to interrupting areas.
  • the invention further encompasses, in particular, if the textile reinforcement within the textile concrete layer consists of several sections, which, however, are positioned in an overlapping arrangement and form an overlap area.
  • the textile reinforcement is designed to be continuous and runs continuously along the surface.
  • the textile reinforcement is designed to be continuous. Continuous reinforcement can also be ensured by overlapping areas or by interruption areas.
  • the invention includes if only a single mat or lattice structure is provided as textile reinforcement within the textile concrete layer. However, the invention also includes exemplary embodiments in which two or more such mats, which are connected to one another or are not connected, are arranged.
  • the textile reinforcement can - before it is bordered on both sides by concrete layers - with a curing agent, e.g. B. be soaked with epoxy.
  • this epoxy mass is cured before the textile reinforcement is bordered on both sides by concrete layers.
  • the impregnation of the textile reinforcement can also be dispensed with.
  • the textile reinforcement is optimally integrated into the concrete matrix by being surrounded by concrete on all sides.
  • the composite wall construction according to the invention enables the construction of structures using extremely narrow but extremely stable walls.
  • the composite wall construction according to the invention enables it to be created as a prefabricated component.
  • the composite construction according to the invention can be produced efficiently in one plant, and can be transported in a simple and inexpensive manner due to the overall very narrow construction.
  • the prefabricated parts can then be connected to each other on site at the construction site and the building erected.
  • the invention also encompasses composite wall constructions which are manufactured on site at the construction site.
  • first wall layer is provided, for example a brick masonry is built, and then the textile concrete layer is cast onto the existing masonry.
  • the textile concrete layer can first be poured on site, and the second wall layer of stone elements can subsequently be bricked or glued to the textile concrete layer.
  • the invention particularly includes exemplary embodiments which are produced “wet-on-wet”. This means that the stones are placed in the textile concrete layer, which is still fresh - before it hardens - or immediately after the masonry has been created from brick, if the mortar has not yet hardened, the textile concrete layer is poured directly onto the masonry or applied to it.
  • this exemplary embodiment there is the advantage that no separating layer is required between the wall layer and the textile concrete layer, or that no separating layer, if any, can form, and that no additional mortar layer is required to embed the textile reinforcement.
  • Applying the high-strength fine-grain concrete mass can be done like applying a plaster using a trowel.
  • the fine concrete mass can also be sprayed or poured.
  • the invention also encompasses composite wall constructions which comprise two wall layers, each consisting of a multiplicity of stone elements, the textile concrete layer being arranged between the two wall layers.
  • the invention advantageously relates in particular to composite wall constructions which are designed as prefabricated parts.
  • a die made of materials such as polyurethane, silicone, plastic, wood or metal can be used in the factory to manufacture the finished part.
  • webs with a trapezoidal cross section for example, are provided at the points at which mortar joints are later to remain in the wall layer.
  • the webs could consist of the material of the matrix, for example made of silicone or polyurethane, and protrude between the stones in order to make the mortar joint a little deeper and at the same time to provide a place for the safe and secure laying of the stones, for example the clinker, to specify.
  • the elastic material of the webs can be suitable to compensate for dimensional tolerances of the clinker and still maintain a clean joint.
  • the stones are then placed, for example, in the recesses between the webs to create the wall layer.
  • the bridges form the mortar joints between the stone elements, which are slightly inward in the finished state.
  • the invention also includes if the mold (die) for producing the finished part is treated with a concrete setting retarder. As a result, any soiling can be washed out more easily after removal of the molding from the mold. In particular, it can be provided that the joints between the stone elements can be washed out down to the grain, thereby imaging is possible which corresponds to the image of a conventional mortar joint.
  • the composite wall construction according to the invention and the methods according to the invention for producing such a composite wall construction described below include, in particular, exemplary embodiments in which the concrete matrix surrounds and covers the textile reinforcement on all sides, the concrete in particular also penetrating the surface of the textile reinforcement in order to achieve an optimal composite effect.
  • the textile concrete layer is poured.
  • This formulation includes versions in which - depending on the toughness of the concrete mass used - the concrete mass is applied to the textile reinforcement or in which the concrete mass is applied to the textile reinforcement.
  • the textile concrete layer has a layer thickness between 0.3 and 5 centimeters. This makes it possible to manufacture very narrow composite wall constructions, that is to say those composite wall constructions which have only a very small wall thickness, but which at the same time ensure a very high load-bearing capacity.
  • the layer thickness of the textile concrete layer is particularly dependent on the application and the materials used for the textile reinforcement and the materials used for the concrete.
  • the minimum layer thickness of a mortar or concrete layer is assumed according to the invention that this is at least three times the specified largest grain.
  • the "Pagel” source of supply given elsewhere for a specific type of concrete or mortar, there is an approximate minimum layer thickness of 3 mm and the other concrete reference shaft “StoCretec” is an approximate minimum layer thickness of 6 mm in the sense of the invention.
  • the first wall layer of masonry or parts of masonry is provided.
  • the invention in particular also includes composite wall constructions in which the first wall layer represents masonry.
  • the bricks can be, for example, bricks or sand-lime bricks or other conventional bricks, in particular block stones.
  • the bricks can be connected to one another by means of mortar or by means of another suitable connecting means.
  • the wall layer can also be provided only by parts of bricks, for example bricks divided in the middle.
  • the first wall layer consists of brick parts
  • prefabricated brick parts are manufactured that have a concrete backing of about 12 to 15 cm.
  • the total construction thickness is therefore about 15 to 20 cm.
  • a textile concrete layer thickness of only up to 4 to 5 cm is sufficient. This results in considerable weight advantages, which come into effect during transport, storage, use of materials, but also, for example, when supporting corresponding components in the building.
  • a composite wall construction according to the invention is designed as a brick lintel, that is, in the manner of a brick facing, which, for. B. is placed over a window, the prefabricated brick part according to the invention can be manufactured much easier.
  • Conventional brick lintels, which are made with heavy concrete, require support via, for example, stainless steel brackets on the supporting masonry.
  • a prefabricated brick according to the invention in accordance with a composite wall construction according to claim 1 - depending on the dimensions - does not require the use of a corresponding bracket, but can at least be designed to be self-supporting in the case of small spans.
  • the lighter prefabricated components can be handled better on the construction site, for example because the people involved, e.g. B. the bricklayer, they can be lifted and transported more easily.
  • a composite wall construction according to the invention can also be used, for example, to cover a roof area.
  • This offers the possibility of producing the building wall and roof in one casting, that is to say in a look, B. may appear monolithic. If the first wall layer is made of bricks, this ensures a permanent and unchanging surface, for example in contrast to a pure concrete surface that turns black and mossy over time.
  • Composite wall constructions according to the invention can, for example, also span large halls with large spans, and in this way function and be used overall as a roof element of a building.
  • the composite wall construction according to the invention can also be used in particular as a floor ceiling.
  • composite wall construction according to the invention can also be used, for example, as a self-supporting, possibly also curved roof shell, which can also span larger spans.
  • the concrete has a dry bulk density of more than 2,000 kg / m 3 .
  • the textile concrete layer thus comprises concrete masses of conventional materials and with usual dry bulk densities, so that conventional concrete components can be used to accomplish the invention.
  • conventional concrete is used to produce the concrete layers.
  • Special high-strength fine concrete is advantageously used to produce the concrete layer.
  • the high-strength fine concrete can advantageously have a maximum grain size of a maximum of 2 mm in diameter.
  • fine concrete can be used with the invention, which can be obtained under the Pagel / Tudalit brands from Pagel Spezial-Beton GmbH & Co. KG, based in 45355 Essen. Repair materials that can be obtained under the brand name StoCretec TG 203 from StoCrete GmbH based in 65830 Kriftel are also suitable as concrete substitutes.
  • the textile reinforcement consists of a flat, in particular limp structure.
  • the structure can be, for example, a fabric, a mat, a net, a grid, a fleece, a scrim, a multi-axial scrim, an embroidery or a braid.
  • the structure can in particular consist of high tensile continuous fibers. It is crucial that the Textile reinforcement consists of reinforcing fibers that can transmit tensile forces. As a result, the load-bearing capacity of the composite wall structure is greatly increased compared to conventional composite wall structures.
  • the textile reinforcement is prestressed.
  • the textile reinforcement can, for example, be placed in a stenter frame or in a gripping device and held under pretension.
  • a tensioning frame can prestress the textile reinforcement along a spanned plane.
  • the invention also includes if the textile reinforcement is prestressed outwards along a curved surface - also along a multi-curved surface. Of course, this requires a more complicated clamping device.
  • the prestressing achieved by a tensioning device is applied to the textile reinforcement until it is surrounded by concrete on both sides and the concrete has hardened. Only then can the pre-stressed textile reinforcement be released from an appropriate gripping device or from a stenter. After the prestressing forces have been released, the textile reinforcement wants to contract, but is prevented by the concrete edging on both sides.
  • the prestressed textile reinforcement exerts compressive forces on the concrete and prestresses the textile concrete layer consisting of textile reinforcement and concrete edging as a whole.
  • Components pretensioned in this way can withstand larger loads before an initial crack occurs.
  • the deformation behavior is also improved overall.
  • the composite wall construction according to the invention can thus be made leaner and thus lighter by this advantageous embodiment of the invention.
  • the invention also includes if not the entire textile reinforcement is subjected to a prestress, but only parts or sections or individual strands of such a textile reinforcement.

  • a prestressing of the textile reinforcement can also be achieved in one embodiment of a composite wall construction according to the invention in the following way: If the wall layer of the composite wall construction composed of a large number of stone elements, for example bricks, is created completely or at least partially, the wall layer can be used as a tenter frame or as Act as part of a stenter. For example, after a wall layer, in particular a brick layer, has hardened, the edges of the textile reinforcement can be fixed to the wall layer on one or two sides or on more than one side, for example concreted in or concreted in or screwed on there. The wall layer can thus act as a pressure abutment.
  • the invention also includes if the textile reinforcement is fixed on one or more sides to the wall layer, and a prestress is subsequently exerted on the textile reinforcement by using tensioning elements, such as screws, hydraulic elements or under leverage, that is to say by mechanical action.
  • tensioning elements such as screws, hydraulic elements or under leverage
  • a prestress on the textile reinforcement in the case of fixation relative to the wall layer can also be achieved by changing the position or location of one or more elements of the wall layer.

  • the arrangement of a separate tenter frame can be dispensed with.
  • the wall layer or the component or several components can act here as a clamping device or as part of a clamping device.
  • Curved, prestressed textile reinforcements can also be realized in this way: for example, the invention includes exemplary embodiments in which a textile reinforcement is fixed at the ends of a folded or arched structure that tightens, similar to a dust jacket of a book when it is closed.
  • the reinforcing fibers comprise carbon fibers and / or in particular alkali-resistant glass fibers and / or aramid fibers and / or Basalt fibers and / or ceramic fibers. Natural fibers such as sisal are also suitable for carrying out the invention. This embodiment enables conventional fiber materials to be used to provide the reinforcing fibers.
