Description

Component

The invention relates to a component made from two parallel wire mesh mats, from which the wire mesh mats are held at a predetermined mutual distance, straight web wires connected at both ends to the two wire mesh mats, and from an insulating body arranged between the wire mesh mats and penetrated by the web wires.

From AT-PS 372 886 a method and a device for producing a component of this type are known. First, two wire mesh webs are brought into a parallel position in a mutual distance corresponding to the desired thickness of the lattice body to be produced. An insulating body is inserted into the space between the wire mesh sheets and at a distance from each wire mesh sheet. Web wires are guided through one of the two wire mesh webs into the space between the insulating bodies in such a way that each web wire comes to lie close to one of the two wire mesh webs, whereupon the web wires are welded to the wire mesh of the wire mesh webs. Finally, components of appropriate length are separated from the lattice body produced in this way.

From US Pat. No. 3,305,991 a component is known which consists of a three-dimensional grid body, in which a one-piece insulating body is foamed in situ. The lattice body has two wire lattice mats arranged at a distance from one another, which are connected with the aid of zigzag-shaped web wires. At the construction site, the component is provided with a layer of concrete or mortar on both of its top surfaces. The disadvantage here is that, due to the complicated manufacturing process, it is difficult to change the shape and dimensions of the component, in particular to adapt to different static requirements, and that only in situ foamable materials can be used as the material for the insulating body. A further disadvantage is that the web wires are connected to the grid wires only at one point at their wave apexes. A component is known from US Pat. No. 4,104,842, the three-dimensional lattice body of which likewise has two wire mesh mats arranged at a distance from one another and bridging wires of zigzag shape connecting the wire mesh mats. On the inside of and at a distance from at least one wire mesh mat, a cover layer of building paper is attached, which serves as a boundary layer of the concrete shell to be subsequently applied. If two cover layers are used, a cavity is created in the interior of the component which can subsequently be filled with material. Disadvantages are again the complicated manufacturing process, which makes it difficult to change the shape and the dimension of the component, and the restriction of the materials for the insulating body to materials that have to be free-flowing or flowable in order to allow the hollow space of the zigzag To be able to fill components. Another disadvantage is that the web wires are connected to the grid wires at only one point on their shaft apices.

The object of the invention is to provide a component of the type specified in the introduction which can be produced in a simple manner and can be quickly adapted to different static requirements. The component is also intended to enable the selection of different materials for the insulating body and to facilitate the application of the concrete layer at the point of use of the component. The component according to the invention is characterized in that at least one of the wire mesh mats is designed as a mesh reinforcement mat which has a minimum strength of the welding nodes corresponding to the structural requirements for the component, a corresponding mechanical strength of the mesh wire as well as a corresponding diameter and mutual spacing of the mesh mats ¬ wires that the web wires are arranged in predetermined directions to the wire mesh mats and that the Isolier¬ body is held at a predetermined distance from each of the wire mesh mats.

Compared to the known components with zigzag-shaped bridge wires and only one welding spot in the area of the wave apex, the component according to the invention has the advantage that the bridge wires are designed as individual wires and therefore there are two welding spots in the connection area with the wire mesh wires, so that the static safety is practically doubled.

Preferably, in the component according to the invention, the web wires are arranged alternately obliquely in opposite directions, between the wires of the wire mesh mats, in the manner of a truss. Alternatively, the web wires can be arranged between the wires of the wire mesh mats in rows with web wires inclined in the same direction within them, the direction of direction changing from row to row. According to another variant of the invention, the web wires can run perpendicular to the wire mesh mats and the position of the insulating body relative to the wire mesh mats can additionally be fixed by a plurality of spacers supported on the wires of the wire mesh mats. In a preferred embodiment of the invention, the lattice body formed from the wire mesh mats and the web wires is reinforced at least on two opposite edges by edge web wires which are preferably perpendicular to the wire mesh mats and welded to the wire mesh edge wires. The lattice mat wires at the edge of the wire lattice mats are preferably flush with the respective lattice mat edge wires.

In the context of the invention, the insulating body preferably consists of a dimensionally stable material which is expediently sound and heat insulating.

According to the invention, however, two separation layers arranged at a predetermined distance from the wire mesh mats, which are defined by the web wires and / or the spacers and which enclose an intermediate space with a predetermined width, may also be provided, the intermediate space preferably being used to form a central insulating layer -, pourable or flowable materials can be filled, which are preferably sound and heat insulating.

For the practical use of the component as a wall or ceiling element, it is particularly advantageous if at least one wire mesh mat laterally projects beyond the insulating body or the central insulating layer on at least one side surface of the insulating body or the central insulating layer. It can on the outside to form the exterior of the component determined An outer shell made of concrete can be applied, which adjoins the insulating body or the separating layer adjacent to the outer wire mesh mat, encloses the outer wire mesh mat and forms the load-bearing component of the component together with the latter.

According to a further feature of the invention, an inner shell is applied to the inner wire mesh mat intended to form the inside of the component, which connects to the insulating body or to the separating layer adjacent to the inner wire mesh mat, encloses the inner wire mesh mat and together with it the load-bearing component of the Component forms.

21 shows a side view of a component, each with two separating layers and two plaster support grids and an intermediate insulating material layer. The component shown in FIG. 1 consists of two flat wire mesh mats 1 and 2, which are arranged parallel to one another at a predetermined distance. Each wire mesh mat 1 and 2 consists of several longitudinal wires 3 and 4 and of several transverse wires 5 and 6, which cross each other and are welded together at the crossing points. The mutual spacing of the longitudinal wires 3, 4 or the transverse wires 5, 6 to one another is selected in accordance with the static arrangements on the component. The distances are preferably of the same size, for example in the range from 50 to 100 mm, so that the respectively adjacent longitudinal and transverse wires form square meshes. In the context of the invention, the meshes of the wire mesh mats 1, 2 can also be rectangular and have, for example, short side lengths of 50 mm and long side lengths in the range from 75 to 100 mm. The diameters of the longitudinal and transverse wires are also selected in accordance with the static requirements and are preferably in the range from 2 to 6 mm. The surface of the grid wire can be smooth or ribbed in the context of the invention.

The two wire mesh mats 1, 2 are connected to one another by a plurality of web wires to form a dimensionally stable spatial lattice body. The web wires 7 are welded at their ends to the wires of the two wire mesh mats 1, 2, whereby in the context of the invention the web wires 7 either, as shown in the drawing, with the respective longitudinal wires 3, 4 or with the transverse wires 5, 6 are welded. The web wires 7 are alternately inclined in opposite directions, i.e. arranged in the manner of a truss, which stiffens the lattice body against shear stresses.

The spacing of the web wires 7 from one another and their distribution in the component depend on the structural requirements for the component and are, for example, 200 mm along the longitudinal wires and 100 mm along the transverse wires. The mutual spacing of the web wires 7, 7 'in the direction of the grid mat longitudinal wires 3, 4 and the grid mat cross wires 5, 6 expediently make a multiple of the mesh pitch. The diameter of the bridge wires is preferably in the range from 3 to 7 mm, with the diameter of the bridge wires being preferably chosen to be larger than the diameter of the longitudinal and transverse wires in the case of components with thin longitudinal and transverse wires.

Since the spatial lattice body formed from the two wire mesh mats 1, 2 and the web wires 7 not only has to be dimensionally stable, but also has to fulfill the function of a spatial reinforcement element in its preferred use as a wall and / or ceiling element, ie Has to absorb shear and compressive forces, both the longitudinal and transverse wires are welded to one another, as is customary in the case of reinforcement mats, and the web wires 7 are welded to the grid mat wires 3, 4, 5, 6 while observing a minimum strength of the welding nodes. In order to be able to fulfill the function of a spatial reinforcement element, the wire mesh wires 3, 4, 5, 6 and the bridge wires 7 must consist of suitable materials and have appropriate mechanical strength values in order to be used as reinforcing wires to be usable for the wire mesh mats 1, 2 to be used as mesh reinforcement mats or as reinforcing wires connecting the two wire mesh mats 1, 2.

In the context of the invention it is also possible to connect the web wires 7, 7 'at their two ends, for example by means of plastic cord knots or bridging. Alternatively, the web wires 7, 7 'can be connected at one end in the aforementioned manner and at their other end by means of welding to the wire mesh wires 3, 4, 5, 6. In the space between the wire mesh mats 1, 2 an insulating body 8 is arranged at a predetermined distance from the wire mesh mats and in the center thereof, which serves for heat insulation and sound insulation. The insulating body 8 consists, for example, of foam plastics, such as polystyrene or polyurethane foam, foams based on rubber and rubber, lightweight concrete, such as autoclave or gas concrete, porous plastics, porous substances based on rubber and rubber, and pressed slag , pressed sludge, plasterboard, cement-bonded press plates made from wood chips, jute, hemp and silica fibers, rice husks, straw waste, sugar cane filling, mineral and glass wool, corrugated cardboard, pressed waste paper, bound brick chippings, melted recyclable plastic waste, tied reeds and bamboo tubes. The insulating body 8 can be provided with pre-drilled holes for receiving the web wires 7. The insulating body 8 can also be provided on one or both sides with a plastic or aluminum layer serving as a vapor barrier. The position of the insulating body 8 in the component is determined by the obliquely running web wires 7 which penetrate the insulating body 8.

The thickness of the insulating body 8 is freely selectable and is, for example, in the range from 20 to 200 mm. The distances between the insulating body 8 and the wire mesh mats 1, 2 can also be freely selected and are, for example, in the range from 10 to 30 mm. The component can be produced in any length and width, a minimum length of 100 cm and standard widths of 60 cm, 100 cm, 110 cm and 120 cm having proven advantageous on the basis of the production process. As can be seen from the top view of the component shown in FIG. 2, the longitudinal wires 3 and the longitudinal edge wires 3 'each terminate flush with the edge transverse wires 5' and the transverse wires 5 and the edge transverse wires 5 'each flush with the edge of the component with the edge longitudinal wires 3 '. The same applies analogously to the wire mesh wires 4, 4 ', 6, 6' of the other wire mesh mat 2.

FIG. 3 shows a side view of the component according to FIG. 1, viewed in the direction of the cross wire array. The web wires 7, which run alternately in opposite directions and obliquely to one another, form a row and are each welded to the corresponding longitudinal wires 3 and 4 of the wire mesh mat 1 and 2 arranged one above the other.

4 and 5 each show exemplary embodiments with different angles between the land wires 7 and the corresponding longitudinal wires 3, 4 of the wire mesh mats 1, 2, wherein according to FIG. 5 different angles within a row of land wires are also possible.

6 shows a component in which in one row the web wires 7 run obliquely in the same direction between the longitudinal wires 3 and 4 of the wire mesh mats 1, 2, while in the next row the web wires 7 'shown in dashed lines also run obliquely in the same direction, but with the opposite Direction of direction run between the corresponding longitudinal wires, ie the component has several rows of diagonally inclined bridge wires with changing direction from row to row. In the context of the invention, the rows of web wires of the same inclination can also run between the transverse wires 5, 6 of the wire mesh mats 1, 2. 7 shows a component with oppositely inclined ridge wires 7 per row, the spacing of adjacent ridge wires in the row being selected such that the ends of the ridge wires facing each other come as close as possible, whereby possibly two ridge wires together in one arm. can be welded with the appropriate wire mesh.

Within the scope of the invention, the web wires 7, as shown in FIG. 8, can also be arranged perpendicular to the wire mesh mats 1, 2. In this case, since the position of the insulating body pers 8 in the lattice body is only insufficiently fixed by the web wires 7, several spacers 9 are provided for fixing the insulating body 8, each of which is supported on the corresponding lattice mat wires of the wire lattice mats 1, 2. The spacers 9 are also used in the case of components with inclined web wires 7 if, due to the material properties of the insulating body, the web wires do not ensure that they are fixed in the lattice body. This applies, for example, to insulating bodies made from reeds or bamboo that are bound together.

As FIG. 9 shows, the insulating body 8 can also be arranged asymmetrically to the two wire mesh mats 1, 2. The diameters of the grid wires 4, 4 ', 6, 6' of the wire grid mat 2 lying further away from the insulating body 8 are advantageously larger than the diameters of the grid wires 3, 3 ', 5, 5 * of the wire grid mat 1 closer to the insulating body 8.

For stiffening the grid body at its edges, additional, preferably perpendicular to the wire grid mats 1, 2 and with the corresponding edge grid wires 3 ', 4 ", 5', 6 'of the wire grid mats 1, 2 can be used according to FIGS. 1-0 welded edge web wires 10. The diameter of the edge web wires 10 is preferably equal to the diameter of the web wires 7, 7. 'A component according to the invention is shown in Fig. 11, the insulating body 8 of which is parallel to the cross wires 5, 6 extending side surfaces 11 does not terminate with the two wire mesh mats 1, 2, but is overhanged laterally by this embodiment. When two identical components are linked, this embodiment ensures that the insulating bodies of adjacent components can be arranged without a space, while the wire mesh mats of the two components each overlap one another and thereby a load-bearing overlap The insulating body 8 can also end flush on its two side surfaces 11 with the inner wire mesh mat 2 and only protrude beyond the outer wire mesh mat 1 in practical use. One or both of the wire mesh mats can also laterally protrude the insulating body 8 on all side faces thereof. In these exemplary embodiments, any edge web wires 10 can be arranged such that they run outside the insulating body or connect to it laterally.

The longitudinal and transverse wires of the wire mesh mats 1, 2 and the web wires can have any cross section. The cross sections can be oval, rectangular, polygonal or, as shown in FIG. 12, square. The reference numerals for the corresponding wires are 3 "and 4" for the square longitudinal wires, 5 "and 6" for the square transverse wires and 7 "for the square bridge wires.

13 shows a component which has a two-part insulating body 8 '. If necessary, the parts of the insulating body can be glued to one another at their contact surfaces. To save material, the two parts of the insulating body 8 'enclose cavities 12 which, however, are also filled with other materials, for example pourable, pourable and flowable insulating materials, such as wood and foam chips, sand, plastic, rice or straw waste can be. The insulating body 8 'can also consist of several parts which can be connected to one another, for example have a multilayer structure. It is also possible to provide a one-piece insulating body 8 with cavities 12.

As shown schematically in FIGS. 14 and 15, an outer shell 13, for example made of concrete, is applied to the outer wire mesh mat 1 intended to form the component exterior, which connects to the insulating body 8, encloses the outer wire mesh mat 1 and together with it the load-bearing component of the component according to the invention. The thickness of the outer shell 13 is selected in accordance with the static, sound and thermal requirements for the component and is, for example, 20 to 200 mm. If the component is used as a ceiling element, the minimum thickness of the outer shell 13 must be 50 mm for structural reasons.

An inner shell 14 is placed on the inner wire mesh mat 2 intended to form the inside of the component. brings that connects to the insulating body 8, encloses the inner wire mesh mat 2 and is made of concrete or mortar, for example. The thickness of the inner shell 14 is selected in accordance with the static, sound and thermal requirements for the component and is, for example, 20 to 200 mm. The two shells 13, 14 are preferably applied at the place of use of the component, for example sprayed on using the wet or dry method.

Since the partial areas of the bridge wires 7, 7 'and possibly also the edge bridge wires 10 lying in the interior of the component are not covered with concrete and are therefore exposed to corrosion, the wires 7, 7' or 10 must have a corrosion protection layer be provided. This is preferably achieved by galvanizing and / or coating the wires 7, 7 'or 10. For reasons of cost, it has proven advantageous to use galvanized wire at least for the web wires 7, 7 'during the manufacture of the lattice body. The wires 7, 7 'and 10 can also be made of stainless steel or of other non-corrosive materials, e.g. Aluminum alloys are produced, which must be connectable, preferably weldable, to the wire wires of the wire mesh mats 1, 2. In the context of the invention, just like the web wires 7, 7 'and 10, the wire mesh wires of the wire mesh mats 1, 2 can also be provided with a corrosion protection layer or consist of stainless steel qualities or of other non-corrosive materials.

For structural reasons and / or to increase the sound insulation, it may be necessary to provide the component on at least one component side with a very thick concrete shell with a two-layer reinforcement. 16a shows a detail of a component with a very thick outer shell 13 'made of concrete, the outer shell 13' being reinforced with an outer, additional reinforcement mat 15, the distance from which to the outer wire mesh mat 1 is shown in accordance with the statistic Requirements for the component is freely selectable. The outer additional reinforcement mat 15 prevents cracks in the outer shell 13 'caused by temperature and shrinkage stresses. For structural reasons and / or to increase the sound insulation, the component can also be provided with a very thick inner shell 14 ', this either only with an inner wire mesh mat 2 or, as FIG. 16b shows, with an inner wire mesh mat 2 and one inner, additional reinforcement mat 15 'is reinforced. The distance between the inner additional reinforcement mat 15 'and the inner wire mesh mat 2 can be freely selected in accordance with the structural requirements for the component. The diameters of the grid wires of the inner additional reinforcement mat 15 'are preferably larger than the diameters of the grid wires of the two wire grid mats 1, 2 and are, for example, in the range from 6 to 6 mm. If the thick inner shell 14 'is reinforced only with the inner wire mesh mat 2, the diameters of the wire mesh 4, 4', 6, 6 'of the inner wire mesh mat 2 and the web wires 7, 7' are preferably larger than the diameter of the wire mesh 3, 3 ', 5, 5' of the outer wire mesh mat 1 and are, for example, in the range from 5 to 6 mm.

The inner wire mesh mat 2 and the inner additional reinforcement mat 15 'can be connected by a plurality of spacer wires 24, which preferably run perpendicular to the inner wire mesh mat 2 and inner additional reinforcement mat 15' and the mutual, lateral spacing of which can be freely selected. The diameter of the spacer wires 24 is preferably the same as the diameter of the grid wires of the wire grid mats 1, 2.

Within the scope of the invention, the outer additional reinforcement mat 15 and the outer wire mesh mat 1 can also be connected with spacer wires, which preferably run perpendicular to the outer wire mesh mat 1 and outer additional reinforcement mat 15. These spacer wires are arranged at selectable lateral distances from one another and have diameters which are preferably the same as the diameters of the grid wires of the two wire grid mats 1, 2.

The thick concrete shells 13 'and 14' provided with two-layer reinforcement can also be cast from in-situ concrete at the place of use of the component, the outer boundary of the concrete shells 13 ', 14' being formed by a casing, not shown. As FIG. 17 shows, instead of the inner concrete shell, a lining plate 16 can be arranged on the inside of the component, which lies on the inner wire mesh mat 2 and is fastened to an assembly aid device 17. The lining plate 16 forms the non-load-bearing inner wall of the component and, since it does not have to fulfill any static tasks, can be made of lightweight construction material, such as a plywood board, a plasterboard plate and the like. exist and be designed decoratively according to the equipment requirements for the interior. The auxiliary assembly device 17 is arranged between the insulating body 8 and the inner wire mesh mat 2 and consists, for example, of a plurality of strips which run in a vertical direction between the web wires, provided that the component is used as a wall component. The assembly aid 17 can, if necessary, be attached to the wires 4 or 6 of the inner wire mesh mat 2, for example by means of staples not shown, or to the insulating body 8, for example by means of an adhesive layer. The assembly aid device 17 must consist of a suitable material, for example of wood, which ensures that the lining plate 16 is securely anchored to the inner wire mesh mat 2 located therebetween. As a result of the configuration according to the invention, the lining plate 16 is not fastened to the insulating body 8, which naturally does not permit secure attachment due to its material properties, but is firmly anchored to the inner wire mesh mat 2 or clamped against it.

In order to improve the adhesion to the two cover surfaces 18 of the insulating body 8, 8 ′ facing the wire mesh mats 1, 2 and to prevent undesired flow of the material during processing, the cover surfaces 18 can be used to improve the adhesion when the outer shell 13 and the inner shell 14 are made of concrete of the insulating body 8, 8 'are roughened. As shown in FIG. 18, the cover surfaces can be provided with depressions 19, for example with the aid of gears or rollers which have spikes or knobs on their circumference, during the manufacture of the component in the cover surfaces 18 of the insulating body be shaped. In the context of the invention, it is possible according to FIG. 19 to provide the insulating body 8, 8 'on its top surfaces 18 with transverse grooves 20 which run in the horizontal direction when the component is used as a wall element. The depressions 19 and the transverse grooves 20 can also be produced within the scope of the invention during the manufacture of the insulating body.

To improve the adhesion of the outer concrete shell 13 to the insulating body 8, 8 ', a plaster support grid 21 can be used, as shown in FIG. 20, which rests on the top surface 18 of the insulating body 8, 8' and through the web wires 7 or the insulating body 8, 8 'is fixed. The plaster support grid 21 consists, for example, of a fine-mesh welded or woven wire grid with a mesh size of, for example, 10 to 25 mm and wire diameters in the range from 0.8 to 1 mm. The plaster support grid 21 can also consist of expanded metal within the scope of the invention. An additional separating layer 22 made of, for example, impregnated construction paper or cardboard can be arranged between the plaster base grid 21 and the top surface 18 of the insulating body 8, 8 ', which also serves as a vapor barrier and is preferably connected to the plaster base grid 21.

21 shows a further exemplary embodiment of a component according to the invention, two separating layers 22 being arranged in the component at a selectable distance from the respectively adjacent wire mesh mat 1 or 2 and at a selectable distance from one another such that between a space 23 is formed between the separating layers 22. The separating layers 22 can consist, for example, of cardboard, cardboard, plastic panels, thin plasterboard panels or concrete panels with or without reinforcement. The separating layers 22 are either fixed by the web wires 7 or with the aid of spacers in their position relative to the wire mesh mats 1, 2. The space 23 between the separating layers 22 is filled with suitable insulating material either during the manufacture of the component or only at the place of use of the component, as a result of which a central insulating layer 8 "is created in the component. Since the separating layers 22 form the boundary surfaces of the central insulating layer 8 ", it is possible to use materials to build up the insulating layer do not have to be dimensionally stable or self-supporting. The materials should, however, be pourable, pourable or flowable and can consist, for example, of in-situ foamable plastics, plastics, rubber or wood waste, foam chips, sand, slag, expanded concrete, rice or straw waste or brick chips. A plaster support grid 21 can also be arranged on the surfaces of the separating layers 22 facing the wire mesh mats 1 and 2.

It goes without saying that the exemplary embodiments described can be modified in various ways within the framework of the general inventive concept; in particular, it is possible to attach the outer shell 13 and / or the inner shell 14 or the lining plate 16 to the component in the manufacturing plant. The insulating body 8, 8 'and the central insulating layer 8 "as well as the separating layers 22 can consist of flame-retardant or non-flammable materials or can be impregnated or provided with substances which isolate the insulating body 8, 8', the central insulating layer 8" and make the separating layers 22 flame-retardant or non-flammable. The insulating body 8, 8 'and the separating layers 22 can also be provided with a flame-retardant or non-flammable coating.

In the context of the invention it is further possible that the insulating body 8, 8 'or the central insulating layer 8 "on at least one side surface 11 of the insulating body 8, 8' or the central insulating layer 8" laterally protrudes at least one wire mesh mat 1, 2.
