Description

The present invention relates to a prefabricated part of a plurality of substantially mutually parallel elements, which are made of hardenable casting compound and which are interconnected by at least one reinforcement device with a connecting device.

Reinforcement devices are known in high numbers and many embodiments.

DE 72 40 114 U discloses a reinforcement device for prefabricated parts, which consist of mutually parallel elements, which are made of curable casting compound and interconnected by connecting devices, wherein the connecting devices corrugated sheet-like surface are formed multi-dimensionally and with the elements of hardenable casting compound a zug-, pressure and Shear-resistant composite form.

US Pat. No. 2,088,645 A and US 2005/0155306 A1 show reinforcement devices for prefabricated parts, which consist of mutually parallel elements, which are made of hardenable casting compound and interconnected by connecting devices, wherein the connecting devices of grid-shaped arranged and interconnected rods, which lie in one plane. US 2005/0155306 A1 further shows three-dimensionally bent connecting bracket 2, with which juxtaposed and stacked prefabricated parts can be connected to each other by the connecting bracket are hooked to the lattice-shaped connecting devices of adjacent FertigBauteile.

From the DE 2 139 197 A1 It is known to provide two cast or sprayed shuttering as lost formwork in buildings with lost formwork and to use a Baustahlgewebe in the cast shuttering walls so that the nodes in the still liquid Plastic of the shuttering walls are pressed so that the nodes of the reinforcing bars of Baustahlgewebes are completely enclosed after curing of the plastic. Structural steel mesh is difficult to handle and must be adapted to the individual requirements of the individual case, which complicates a rational production of finished parts and expensive.

Another solution for the manufacture of prefabricated construction is in the DE 2 305 651 A1 shown and described. There, too, the disadvantages of Moniereisen-deposits and Baustahlgewebe are discussed in detail, in particular, the cumbersome, expensive and time-consuming preparation and processing are listed in this document. In contrast, the production of cast-ready reinforced concrete should be facilitated by the invention described therein that hardening elements, such as steel rods are added to the cast concrete in small and / or larger versions during casting. The steel rods should be specially shaped. As exemplary deformations there is specified that they should be so surface deformed that they continuously in the axial direction of their cross section in a smooth transition continuously from flat to square to round and turn to square too flat respectively about the axis - preferably 180 ° - and be repeatedly deformed, the material cross section remains approximately always in the same cross-sectional size. These continuously deformed rods are bent in their longitudinal axis so that each rod occupies a flat, spiral shape, wherein the rotation of this spiral is preferably about 1 1/2 revolutions, that is rotated by about 540 °. Understandably, the shape of the rods described by the drawings attached there. As advantages, a reduced rate of sinking in cast concrete due to the special shape are cited there. In addition to the contact with the outer surfaces of the finished part to be cast be minimal, and as a result of the 540 ° twisting and bending a better bond with the cast concrete are produced, which is to provide the highest possible additional strength and elasticity with minimal use of steel. Further advantages are given in the description there.

From this document, however, it is not apparent how the static stability of the finished parts to be cast could be determined specifically. Furthermore, it can not be deduced that a defined combination of outer shells and cast concrete could come about. In summary, the document does not show how reinforcing elements could be designed, which can be used in multi-shell prefabricated parts and their strength can be determined defined.

In contrast, the invention is based on the object to provide a prefabricated part with a reinforcing device, which does not have the disadvantages of the prior art, and when used in the manufacture of finished parts and the latest regulations in terms of statics, thermal insulation, corrosion resistance and the like ., But nevertheless has a low mass, low cost in the production caused and allows a simple and therefore cost-effective processing.

Moreover, it is advantageous if the composite component extends in a plane which runs perpendicularly between the elements arranged parallel to one another, wherein the outer edges of the composite component facing the mutually parallel elements can be positively anchored in their curable casting compound.

A connecting device is also particularly advantageous if the tension and / or pressure elements can be arranged between the elements arranged parallel to one another and configured such that they can be anchored in a form-fitting manner in their hardenable casting compound.

It may also be advantageous if the tension and / or pressure elements are designed in several parts.

In FIG. 1 is a prefabricated part 1 shown in the form of a double-shelled wall. A double-walled wall here consists for example of two mutually parallel elements 2 and 3, which are also referred to as inner 2 and outer shell 3. In the two inner 2 and outer shells 3 respectively mild steel or Baustahlgewebe 4, 5 is cast, each already in the production of the individual shells, as described in an earlier, but not yet published application of the applicant in detail. The reference numeral 6 denotes a connecting device, which is shown above the prefabricated part 1. The connection device 6 has a plurality of tensile and / or pressure elements 7, which are interconnected by a composite component 8. The composite component 8 is located between the free ends of the tension and / or pressure elements 7 and is spatially set back relative to these. The connecting device 6 is in the case of an already completed wall - which was formed by the prefabricated part 1 - between the inner shell 2 and the outer shell 3, that is different from the illustration in FIG FIG. 1 , In FIG. 1 is to be illustrated, in which orientation the connecting device 6 between the inner shell 2 and the outer shell 3 is to be positioned. An arrow 9 makes this clear. After the connecting device 6 positioned in its position between the inner shell 2 and the outer shell 3 and the bivalve wall is positioned vertically in the manufacture of the prefabricated part 1, it is filled with hardenable casting compound, here with concrete G. The connecting device 6 is then used to stiffen the prefabricated part 1 by being formed multi-dimensional surface and forms a tensile, compressive and shear-resistant composite with the elements 2 and 3 of curable casting.

In FIG. 2 is a prefabricated part 1 with inserted connecting device 6 illustrated in partial section, and in FIG. 3 is a connecting device 6, as in the embodiment in FIG. 2 is used, shown in cross section. As in FIG. 2 illustrated, the composite member 8 is anchored with its extending at the outer edges 10 areas in the mutually parallel inner and outer shells 2 and 3. This anchoring takes place by insertion into the not yet cured casting compound G in the production of the individual inner and outer shells 2 and 3. In this case, the tensile and / or pressure elements 7 dive far into the casting mass G. The connecting device 6 has a multi-dimensional surface and forms with the inner and outer shells 2 and 3 of curable casting material G a tensile, compressive and shear-resistant composite. It is advantageous if the tension and / or pressure elements 7 do not extend to the outer surfaces of the inner and outer shells 2 and 3. A sufficient distance between the outer surfaces of the inner and outer shells 2 and 3 and the ends of the tension, pressure elements 7 gives good corrosion protection and good thermal insulation, since cold bridges are avoided. If this requirement is not met, the tensile and / or pressure elements can also penetrate to the outer surfaces of the inner and outer shell 2 and 3. Advantageously, the connecting device 6 with the tensile and pressure-resistant elements 7 made of corrosion-resistant material or corrosion resistant surface-finished. The regions of the outer edges 10 of the composite component 8 are anchored in the manufacture of the elements that make up the inner and outer shells 2 and 3, in this. Each of the elements 2 or 3 is poured in a mold.

This method is well known and should not be exhaustive FIG. 4 only briefly be listed in order to then explain the onset of the connecting devices 6 of the invention can. In a horizontal mold, which has a generally smooth shuttering surface, concrete or other curable Gießmasse G is filled to a predetermined height. The resulting plate of concrete or other hardenable casting material is provided with a reinforcement of structural steel or Baustahlgewebe 4 and poured this by further filling the mold with concrete or other curable casting material G. In this horizontally located, not yet cured slab of cast concrete or other hardenable casting material G, the connecting devices 6 according to the invention are used. This is done in such a way that at least one connecting device 6 with the tensile and / or pressure elements 7 is pressed ahead in the not yet cured casting G. The train and / or Pressure elements 7 slide thereby on the cast-in reinforcement steel wire 4 over and the outer edge 10 of the composite component 8 of the connecting device 6 dives into the casting compound G until it gets in contact with the reinforcing steel fabric 4 and rests there. Subsequently, the casting compound G hardens. After curing, the element 2 is removed from the mold, this cleaned and a new layer of casting material is filled to produce another element 3 (not shown) in the mold, reinforced with reinforcing steel fabric 5 and this completely poured. Before this new plate hardens to a solid element, the already finished element 2 is inserted with the connecting devices 6 and the tensile and / or pressure elements 7 ahead in the not yet cured casting G of the second element 3, until the still free outer edge 11 of the composite component 8 also in this element 3 abuts the Baustahlgewebe 5 and rests there. In this position, the casting compound G of the second element 3 hardens and a reinforced, double-shell prefabricated part 1 is produced. This double-shell prefabricated part 1 is taken out of the mold, placed vertically and is in the position as in FIG. 2 is shown. It can be seen from this illustration that the connecting device 6 is anchored in each case to the regions of the outer edges 10 and 11 of its composite component 8 in the hardened casting compound G of the inner and outer shells 2 and 3, wherein the connecting device 6 has a multi-dimensional surface the elements 2 and 3 of hardenable casting compound forms a tensile, compressive and shear-resistant composite and contributes significantly to the stability of the prefabricated part 1.

In FIG. 5 a connection device 6 is shown in a perspective view. This connecting device 6 corresponds to the previously described connecting devices 6 from the FIGS. 1 to 4 , she is in FIG. 3 shown in cross section. The waveform of the Cross-section of their composite component 8 is particularly well suited to ensure the prefabricated part 1 sufficient stability with low weight, ease of use and low cost. The material suitable for this embodiment, any material with sufficient strength, standard corrugated metal appears particularly advantageous. The design of the tension and / or pressure elements 7 is rod-cylindrical in this embodiment. They are attached to the composite component 8 in any suitable manner.

In FIG. 6 a variant of a connecting device 12 is shown, in which the wave-shaped composite component 13 is made of stronger material, such as fiber composite material. In this fiber composite material can be arbitrarily shaped tensile and / or pressure elements insert. To illustrate the various options, several examples are shown here simultaneously on a composite component 13. The reference numeral 14 denotes a tensile and / or pressure element with a straight, prismatic cross-section. The reference numeral 15 stands for a club-shaped tension and / or pressure element. 16 denotes a short-wave bent tensile and / or pressure element and 17 represents a rod-shaped cylindrical tensile and / or pressure element, as in FIG FIG. 5 , By the reference numeral 18, a long-wave curved tensile and / or pressure element is designated and 19 stands for a serrated tension and / or pressure element. The respective cross sections are adapted to the shape.

In a further variant of a connecting device 20 according to FIG. 7 It is shown that still other embodiments for tensile and / or pressure elements are conceivable. With openings 21 in the surface of a composite component 22, the anchoring in the casting material G is further improved. The reference numerals 23 and 24 rod-shaped cylindrical tensile and / or pressure elements are referred to with different diameters. Reference numerals 25 and 26 stand for helical tension and / or pressure elements with different cross sections, also jagged tensile and / or pressure elements with 27 and meandering tensile and / or pressure elements are designated by 28.

In FIG. 8 a further variant of a connecting device 29 is shown, which essentially corresponds to the connecting device 20 according to FIG FIG. 7 equivalent. The composite component 30 has no breakthroughs with respect to the connecting device 20, the tensile and / or pressure elements are largely identical and are therefore provided with the same reference numerals.

FIG. 9 shows a tensile and / or pressure element 31 which is rod-shaped cylindrical, and at its front ends in each case carries a tuft of wires 32, which may be welded, for example.

In the various ways to design the tensile and / or pressure elements is in the FIGS. 10 to 12 Referenced.

In FIG. 10 It is shown that a tension and / or pressure element 33 can also be joined together from several individual parts. In one of these embodiments, there is a hollow cylindrical central portion 33a, in each of which an end piece 33b and 33c can be inserted from both ends by means of a non-descript approach. These three individual parts combine to form a complete tensile and / or pressure element 33, wherein the end pieces 33b and 33c can be bevelled at their respective free end faces. In addition, it is possible to produce a tensile and / or pressure element from a cylindrical central part 33d, on whose end faces in each case a matching end piece 33e and 33f can be attached. Such variations are particularly useful when the middle parts and the end pieces are made of different materials, or if they have different surface finish. The end pieces may, for example, be roughened or otherwise structured in order to be better anchored in the casting compound G.

A very similar variant is in FIG. 11 In this embodiment, there is a hollow cylindrical central portion 34a, in each of which an end piece 34b and 34c can be introduced from both ends by means of a non-descript approach. These three individual parts combine to form a complete tensile and / or pressure element 34, wherein the end pieces 34b and 34c can be beveled at their respective free end faces. In addition, it is possible to produce a tensile and / or pressure element of a cylindrical central portion 34d, on whose end faces in each case a matching end piece 34e and 34f can be attached. Such variations are particularly useful when the middle parts and the end pieces are made of different materials, or if they have different surface finish. The end pieces can be sanded, for example, in order to be better anchored in the casting material G.

In FIG. 12 again a detail of an inner shell 2 is shown, in which a tensile and / or pressure element 35 is anchored in the casting material G. The end face of the tension and / or pressure element 35 has a teardrop-shaped end region 36, which is fixed in a form-fitting manner in the casting compound G. The unspecified outer edge of a likewise unspecified composite component is also anchored in an already described manner in the casting compound and largely corresponds to the above-described embodiments.

In FIG. 13 is shown very schematically an advantageous development of a connecting device according to the invention: A number of tensile and / or pressure elements 37, 38, 39 is interconnected by a composite component 40. The composite component is realized here as an arrangement of parallel wires 40. To improve the fixation in the casting compound G additional wireforms 41 may be provided. This embodiment illustrates the possibility of winding a plurality of connecting devices on a roll and thus make it magazinierbar.

In FIG. 14 It is shown that the tensile and / or pressure elements 42, 43, 44 can also assume small angles to one another, and that they can be connected to one another by a metal strip 45. In this embodiment, the weight is extremely reduced, which ensures lowest material consumption and lowest cost with sufficient strength. Again, the surface of the tensile and / or pressure elements can be structured in any desired manner.

Finally, a connecting device 46 can be realized, in which the composite component 47 has a meandering cross section. The tension and / or pressure elements 48, 49 and 50 are inserted into the meander suitable and can be configured arbitrarily.

Another embodiment is in FIG. 16 shown. On a shuttering plate 51, which is a part of a casting mold, as already described above, a Baustahlgewebe 52 is placed. This Baustahlgewebe 52 stabilizes the inner or outer shell, which is to be poured. A connecting device 53 is provided with rectangular cutouts 54 into which the rods 57 of the structural steel fabric 52 project. Cutouts may also be formed as comb-like cutouts 55 and form the edge of the connecting device 53. The comb-like cutouts 55 engage in the further manufacturing process of the inner or outer shell in the reinforcement formed by the reinforcing steel of the second, later to be cast indoor or Outer shell. A composite of pressure and / or tension elements is provided in this embodiment by a continuous, flat structure 58, which is stabilized by a band as a composite component 59.

The above embodiments make it clear that a connection device according to the invention can be configured in various forms. Thus, the described embodiments are not intended to limit the invention defined in the claims in any way, but rather show that the invention can be configured in many different ways.
