The invention relates to a building module for producing bridges, buildings and towers, for example for wind turbines.

State of the art

Conventional methods work with in-situ concrete for bridge piers and for other tower constructions, including for towers of wind power plants, with so-called pulling formwork or climbing formwork on site, with the construction of such structures or towers usually taking 50 or more working days for just one Bridge pillars or towers are required and costs per building start at around 1.4 million German marks and are uneconomical from the outset. The typical production, manufacturing and construction costs and the associated interest expense as well as the longer production time are much too high according to conventional methods.

From DE 27 42 000 A1 a chimney is known, with an outer jacket, with an inner lining and with a reinforcement, which extends partly in the longitudinal direction of the chimney and partly in the form of a closed ring reinforcement in a radial plane to the longitudinal axis of the chimney, the The jacket and the lining are made up of prefabricated and superimposed, ring-shaped jacket and lining elements, a radial distance being provided between the jacket elements and the lining elements and the longitudinal reinforcement being arranged in an intermediate space formed by this distance and cast with in-situ concrete. The jacket elements are provided with ring reinforcement. The total required ring reinforcement is arranged partly in the casing elements and partly in connection with the longitudinal reinforcement in the space poured with in-situ concrete. The lining elements are stepped towards their lower end surface from the outside inwards, the upper end surface of the lining elements being adapted to this shape in each case. Furthermore, the jacket elements are stepped towards their lower end surface from the inside to the outside, the upper end surface of the jacket elements being adapted to this shape in each case. Spacers serve to maintain a certain radial distance between the reinforcement provided in the intermediate space and the casing and lining elements and / or the part of the ring reinforcement connected to the longitudinal reinforcement. The jacket and the lining are constructed from prefabricated elements, at least the required longitudinal reinforcement being used in an intermediate space formed between the jacket and the lining, and the intermediate space is then poured with in-situ concrete. With a chimney designed in this way, the casing elements only need to be provided with ring reinforcement, which is intended to simplify production. The longitudinal reinforcement is inserted on site into the space between the stacked casing and lining elements and poured with in-situ concrete. The concrete binds to the jacket and the lining. Since, when the cladding elements are placed on top of one another, it is no longer necessary to ensure that the passageways used to introduce the longitudinal reinforcement are aligned, and since in-situ concrete can be poured without the need for formwork, the effort required to manufacture the chimney should be reduced. Ring reinforcement is understood to be a circumferential or closed reinforcement in the circumferential direction.

DE 187 412 describes a mold for producing chimneys made of concrete or similar material with an adjustable inner and outer jacket and air duct shapes arranged at intervals between them. The shape should be easy to take apart and be adjustable for different chimney diameters, without inner and outer struts obstructing the chimney opening and the surrounding area. The shape consists essentially of one Outer jacket and the inner jacket. The outer jacket is composed of any plates that are made of sheet iron. One or more of the panels, cut to the appropriate length and width, are detachably arranged so that the shell diameter of the shape can be changed easily. The plates are surrounded at the top and bottom and at one or more points of their height by reinforcing rings which consist of short ring members articulated to one another. The joints of the ring links are designed as hinges. The individual ring links are connected to the plates by bolts, for which holes are provided. At certain intervals, perforated angles are attached to the reinforcement rings, which serve to hold and support the iron bars, the ends of which pass through particularly strong angles and carry nuts. The rods encircle the articulated reinforcement rings and expediently overlap with their ends. Through the rods and the ring members, when the nuts are tightened, the shell of the mold is firmly stretched and made resistant to the pressure of the concrete stamped into the mold. In addition, the joints of the plates are covered by sheet metal strips, which is to protect the molded jacket against bulges at the joints of the plates. The inner shell of the mold has a construction similar to the outer shell, with the difference that the fastening and stiffening devices are attached to the inside instead of to the outside. From DE 816 598 an assembly method for concrete houses is already known, whereby entire walls, roofs, stair plates, pillars, chimneys, balconies and similarly simple parts or large sections thereof are set up as formwork panels that have already finished surfaces and by iron, which at the same time serve the static reinforcement, are already stiffened and connected to the finished forms. Vertical parts have both sides, whereas horizontal and sloping parts only have surface-ready formwork on the underside. To create cavities for chimneys, hollow pillars and in ceilings and roofs, boxes made of the same surface-ready formwork panels are fastened by iron at a suitable distance to or between the outer panels. Reinforcing bars are designed as lattice girders that can be completely encased in concrete. The formwork panels are already provided with the finished pipes for water, gas and electricity, with downpipes for waste water being hooked in before concreting.

From JP-Abstract 09195584 A a tubular column structure is previously known, the inner and outer tubes delimiting an annular gap between them, into which a multiplicity of T- and L-shaped stud bolts protrude, which are in contact with the inner surface of the outer tube or the outer surface of the inner tube are connected, the annular space and the space located between the L-shaped and T-shaped elements being filled with concrete. The magazine "baumaschinendienst", Issue 11, 1997, pp. 33 and 34, describes the so-called Sky Tower of New Zealand as the tallest building. The top of the building is a cat boom crane that is in the concrete shaft of the tower during the entire construction phase m in diameter also climbed.

DE 198 23 650.6-25 discloses a method for producing tall, hollow, tower-like structures of up to 200 meters in height, in particular towers for wind turbines, using reinforced concrete, with the aid of formwork, by means of which A concrete pipe-like concrete core, which forms the tower-like structure, is produced, whereby the formwork is divided in the factory into an internal formwork that delimits the inner concrete wall and an outer formwork that delimits the outer wall of the concrete, and into transportable individual formwork parts, which are included in the factory all reinforcements, spacers and connecting elements are provided, and that the individual formwork parts of the inner formwork and the outer formwork are assembled on site to form formwork pipe sections and the respective outer formwork pipe section is placed over the inner formwork pipe section; or the sectors for the inner formwork are assembled within the prefabricated formwork pipe section of the outer formwork; whereupon after the assembly of the combined formwork pipe sections the placing of the concrete in the between the space formed in the inner and outer formwork pipe section and then another formwork consisting of inner and outer pipe section is placed on the underlying double formwork pipe section and all the necessary connections are made with the previously created formwork, whereupon the concrete is inserted for this double formwork pipe section, until the building has reached an intended height, and that the formwork pipe sections forming the formwork, which are coaxially connected to one another, are left in and on the building. The individual formwork pipe sections are factory-divided into several formwork ring sectors which are connected to one another at the construction site to form the formwork pipe section. After the concrete has been poured in and after a certain setting time, several double formwork pipe sections arranged one above the other are permanently tensioned against the foundation with a predetermined prestressing force by several tension elements arranged in the space between the inner and outer formwork and distributed over the circumference of the double formwork pipe sections. As the height of the structure increases, the number of tension elements is reduced. The length of the formwork pipe sections is divided into a fraction, preferably a small fraction, of the total height of the building. The transverse dimensions of the outer and inner formwork, measured orthogonally to the longitudinal axis of the building, and thus also of the tower-like building, are reduced continuously or in steps from bottom to top. A device for performing this method is characterized in that an outer and inner formwork consisting of several coaxial and one above the other and non-positively connected double formwork pipe sections, which delimit an annular space between them, which serves to hold proven concrete, which forms the wall of the building , wherein each formwork pipe section consists of several interconnected individual pipe section parts and each formwork pipe section of the inner and outer formwork is produced from several interconnected formwork ring sectors, each of the formwork pipe sections being prepared in the factory with reinforcement that serves as reinforcement for the concrete, and that the outer formwork and the internal formwork is used as a static load-bearing formwork.

task

The invention is based on the object of designing a module of the required type in such a way that, with extremely high strength, the production of extremely tall buildings, for example towers for wind turbines of a few hundred meters in height, is also possible. solution

The object is achieved by the features set out in claim 1.

Some advantages

According to the invention, a construction module is produced, which has a flat or curved in the desired manner, for example designed as a ring sector or partial pipe section, on which a reinforcement and head bolts are optionally arranged, with a correspondingly thick layer depending on the requirements on the support shell of polymer concrete is arranged. This polymer concrete usually reaches its full load capacity after 24 hours, so that the module is then fully usable. This means that bridges and towers for wind turbines, for example, can be manufactured in a short time. It is also possible to place the polymer concrete in an annular space and let it harden there.

The surface of the carrier shell, which is made of steel, for example, can be roughened well with a sandblast and sprayed with synthetic resin composite adhesive. The connection between the polymer concrete and the steel ensures a tensile strength of 35 KN / cm ² and in connection with wire mesh as Reinforcement a load size of 44 KN / cm ^{2 is} achieved. The existing steel composite can, for example, be individually manufactured as lost formwork for any load capacity in the manufacture of towers for wind turbines. This makes it possible either to save weight by making the lost formwork correspondingly thinner or lighter in weight, or to achieve a correspondingly higher load capacity with the same wall thickness and the same dimensions.

If reinforcement is mentioned, ring and longitudinal reinforcement can be used.

When using headed bolts, these can be arranged entirely or partially in the polymer concrete, the headed bolts being able to have different lengths. The length and head bolts can be used for spacing, that is, they are supported on the opposite formwork pipe section.

Further inventive configurations

Further inventive configurations are described in claims 2 to 17. In the embodiment according to claim 2, the module is flat. A flat module can usually be used for the production of walls for buildings, but also for bridges. If such a module is used for bridges, other elements, for example empty pipes for arranging cables or the like, can of course also be provided in addition to the usual reinforcements and head bolts, while corresponding anchors, empty pipes or the like for arranging tower-like buildings can be arranged by tension elements.

According to claim 3, the module is spatially curved.

In the embodiment according to claim 4, the module is tubular, while in the embodiment according to claim 5 it is designed as a ring sector.

For the manufacture of tall, hollow, tower-like structures of up to 200 meters in height and more, in particular towers for wind turbines, it may be advisable to provide a lost formwork by means of which a tube-like core consisting of polymer concrete, which forms the tower-like structure, is produced , where the formwork is divided into an internal formwork bordering the inner concrete wall and an outer formwork delimiting the outer wall of the polymer concrete and into transportable individual formwork parts. The individual formwork parts then form the construction module, which are factory-provided with, among other things, all reinforcements, spacers or connecting elements such as head bolts, whereby the formwork parts of the inner formwork and the outer formwork are assembled on site to form formwork pipe sections and the respective outer formwork pipe section is placed over the inner formwork pipe section or but the sectors for the inner formwork are assembled within the prefabricated formwork pipe section of the outer formwork, whereupon after the assembly of the combined formwork pipe sections, the polymer concrete is placed in the space formed between the inner and outer formwork pipe section and then another formwork consisting of inner and outer pipe section is placed on the in each case underlying double formwork pipe section placed and all necessary connections are made with the previously created formwork, whereupon the introduction of the concrete for this double formwork pipe section takes place until the building has reached a predetermined height, the formwork pipe sections forming the formwork which are coaxially connected to one another being left in and on the building. The individual ring sectors or other building modules can have dimensions such that they are transportable, for. B. can be shipped in sea containers. However, instead of pouring the polymer concrete into an annular space, it is also possible to produce the entire module in one mold, that is to say to provide it with the polymer concrete shell - claims 6 and 7.

The polymer concrete that can be used, for example, in the manufacture of towers for wind turbines can have the following composition, for example:

Granite split grit 0.5 to 32 mm, 11 volume percent

Natural stone grain (gravel) 0.5 to 60 mm, 25.5 volume percent

Blast furnace slag, grain size 0.5 to 30 mm, 11.5% by volume, gravel sand, grain size 0.03 to 0.06 mm, 21.4% by volume

Synthetic resins in various compositions with a hardener of 36.6 volume percent - claim 8.

According to claim 9, the polymer concrete has a tensile strength of 35 KN / cm ² and in the case of reinforcement a tensile strength of 44 KN / cm ² .

Further advantageous and inventive configurations are described in claims 10 to 13. In the embodiment according to claim 10, there is a positive connection in the form of a lock with a bolt, which enables a particularly reliable and robust coupling of formwork pipe sections of the inner and outer formwork. This makes it particularly advantageous to manufacture towers for wind turbines.

Bar-shaped bars, which extend over the height of a building module, enable a very permanent and firm positive connection of the building modules (claims 11 and 12). However, it is also possible to form the building modules flat or in a shape which is spatially curved from the circular shape and also to provide lock parts here which are connected to one another in the manner of a hinge by a bolt. In this way, for example, roads, bridges or the like can be manufactured - claim 13.

Further advantageous and inventive configurations are described in claims 14 to 17.

In the drawing, the invention is illustrated - partly schematically - using several exemplary embodiments. Show it:

Fig. 8 is a plan view of a lock (connection) between two building modules;

Fig. 9 is a partial representation of Fig. 8, wherein the lock is in the locked position and Fig. 10 shows the lock shown in Fig. 9 without latch in the open position.

Reference number 1 denotes a flat sheet metal sheet, for example made of steel, on which a layer 2 of composite building material, namely of polymer concrete, is applied. For example, if the thickness of the metal sheet 1 is five millimeters, the thickness of the composite building material layer can be 60 mm, although the invention is not restricted to these dimensions.

Numerous head bolts 3 arranged side by side and / or one behind the other are integrally connected to the metal sheet 1, for example by butt welding, by riveting, gluing or the like, which are embedded in the composite building material 2 with part of their length. The composite building material 2 can be applied in a form not shown.

At the ends, the flat-surface building module 4 can be provided, for example on its end faces, with flanges which are provided with spaced holes, through which suitable fastening means, in particular screws (not shown), pass. Of the flanges, only the flange 5 is identified by a reference number in FIGS. 1 and 3, while only one through hole 20 has been identified. The flanges 5 and Bores 20 can each be the same size, but can also be designed differently if necessary.

Flat modules 4 as shown in FIGS. 1 to 3 can be used, for example, for the production of roads, road sections, bridges, bridge parts, walls of buildings or the like. In contrast to the embodiment shown in the drawing, the headed bolts 3 can be completely surrounded by the composite building material, or can be connected in a suitable manner, for example by welding, to a building module (not shown) of the same or a different design, or else in the plane of End the top of the composite building material as a spacer.

4 and 5, a construction module designed as a ring sector 6 for the production of towers, for example for wind turbines, is shown. This construction module 6 is used to produce a tubular inner formwork for the construction of individual formwork pipe sections, which are factory-divided into several formwork ring sectors 6, which form the construction module 6 in question. These ring sectors 6 are connected to one another on a construction site to form the formwork pipe sections, which is done via flanges. Several individual formwork pipe sections arranged one above the other are put together to form a pipe and flanged together axially. As can be seen from FIGS. 4 and 5, each ring sector 6 has on its outside a plurality of rows of head bolts 7 and 8 of different lengths, which are later entirely or partially arranged in a composite building material 2, for example in polymer concrete.

The support shell is formed by a sheet metal body 21 which is integrally connected at both ends to a round flange, of which, however, only the round flange 9 can be seen from FIG. 4. On the opposite end face of the ring sector 6 there is a round flange of the same type, which has numerous spaced through bores, of which only one of the bores is designated by reference number 10. The opposite round flange can also be provided with such through-bores through which bolts can be inserted when the ring sectors 6 are assembled to form a single formwork pipe section, so that several individual formwork pipe sections arranged one above the other form a tubular inner formwork which is used as lost formwork, i.e. with in the static calculations are included. The high strength of composite building material 2, in particular polymer concrete, results in a very high level of strength, which can either be used to reduce the weight of the entire tower or to increase its strength. In this way, for example, towers for wind power plants of a few hundred meters in height can be built, so that high-performance wind power plants can be built using such building modules, which, for example, have propeller diameters from 70 to over 180 meters with corresponding output sizes. The long head bolts 7 can be supported on the outer formwork, so that the formwork is prevented from bulging. This outer formwork is also formed from individual formwork pipe sections which, like the inner formwork, are constructed from ring sectors 11, as can be seen from FIGS. 6 and 7. These ring sectors 11 also have a sheet metal body 12 as a supporting shell, which, like the inner formwork, is provided on the two opposite end faces with a round flange 13 and 14, respectively. The round flanges 13 and 14, like the ring sectors of the inner formwork, have through bores, of which only the through bores 15 and 16 have been provided with reference numerals. In this way, the formwork ring sectors shown in FIGS. 1 to 5, on the one hand, and FIGS. 6 and 7, on the other hand, can be combined to form individual formwork pipe sections, with a plurality of double formwork pipe sections arranged one above the other after the introduction of the composite building material 2, in particular polymer concrete, and after a certain amount Setting time of, for example, only 24 hours form the tower in question, for example a wind turbine. To produce a high, hollow, tower-like structure of up to a few hundred meters in height and more, a plurality of coaxially arranged and non-positively connected double formwork pipe sections are used as external and internal formwork, which delimit an annular space between them, which holds the composite building material 2 serves and the wall of the building, each formwork pipe section consisting of several interconnected individual pipe section parts and each formwork pipe section of the inner and outer formwork is made of several interconnected formwork ring sectors 6 and 11, each of the formwork pipe sections being provided with reinforcement that is in addition to the headed bolts 7 , 8 or 17, 18 can be provided, the outer formwork and inner formwork being used as statically load-bearing and thus lost formwork.

As can be seen from FIG. 7, numerous bulge strips 19 designed as angle irons are provided on the rear side of the ring sector 11, which are firmly connected to the side of the sheet metal body 12 that forms the support shell 17, 18, for example by welding, screwing or the like could be.

As can be seen from FIG. 8, two adjacent metal sheets 1 and 1 a, that is to say two adjacent flat building modules 4, are connected to one another by a lock. Instead of flat building modules, ring sectors or tubular bowls can of course also be provided, as can be seen in FIGS. 6 and 7. 8, however, the reinforcements and the polymer concrete layer have been omitted, and only the metal sheets 1 and 1a have been illustrated for reasons of clarity. As can be seen, the two building modules are provided with tabs 22 and 23 at their mutually adjacent end sections in one piece with the sheet metal or support shell 1 or 1a in question, for example by welding, riveting or screwing, which lie flat on the same side on the end sections of the support shell 1 or 1a in question and are interlocking, closed, by cranking or The locking parts 24, 25 and 26, 27 obtained in this way and connected in one piece to the tabs 22 and 23 have the same size in the embodiment shown and through which a rod-shaped bolt 28 engages in the locked state and thereby a positive connection between manufactures the lock parts 24 to 27, whereby the building modules are firmly clamped and connected on the end face.

The rod-shaped bolt 28 can be press-fit into the lock parts 24, 25 or 26, 27 so that it does not come loose again. In addition, the latch 28 can be secured in a suitable manner, for example by stops, pins or screws attached to the ends, not shown. But it is also possible to lock 28 by welding, for. B. by spot welding or the like, immovable to arrange after its attachment.

The rod-shaped bolt 28 can, however, also be secured immovably in the longitudinal axis direction and thus locked by a flange, a sheet metal or another component of a building module 4 lying above and / or below it. Instead of letting the building modules 4 or their support shells 1, 1a butt against each other on the end face, it is also possible to leave a gap distance 29 between the end faces, for example two to twenty millimeters, preferably only a few millimeters, for example four to five millimeters.

The gap distance 29 is overlapped by a cover plate 30, which is arranged on the side facing away from the rod-shaped bolt 28 of the support shells 1 and 1a and for example a width of 30 to 60 cm, preferably only a few centimeters, for. B. can have eight to 18 cm. The cover plate 30 can, for example, be connected in one piece at 31 by a continuous weld seam to the relevant support shell 1 a and rest with its other end section against the rear side 32 of the support shell 1 in question. A suitable continuous sealing tape (not shown), a plastic coating or the like can be arranged under this adjoining end section of the cover plate 30. The gap distance 29 is advantageously filled with a stretch-elastic plastic, for example a polymer plastic with rubber-like properties, which is age-resistant to the required extent, possibly lightfast and is resistant to the aggressive water usually occurring on construction sites. A polymer plastic, for example, a polyurethane plastic, silicone or Sikomastic (registered trademark) can be considered. The one in question Elastic plastic can be arranged and applied by a spray gun or in some other way, for example in the corner region of the cover plate 30 and the carrier shell 1a (FIG. 10).

Fig. 8 also reveals that 28 game is shown between the rod-shaped bolt. This game is not drawn realistically, but in practice must be so large that the rod-shaped bolt 28 in question can be easily inserted into the lock parts 24, 25, 26 and 27 over a length of several meters, for example 12 meters, which if necessary with the help of a suitable tool, for example a hydraulically driven tool. The gap distance 29 also compensates for unavoidable tolerance differences to the required extent.

The cover plate 30 can additionally be connected at 33 by a further weld seam to the supporting shell 1a in question.

Of course, it is also possible to reverse the situation, that is to say, for example, to connect the cover plate 30 to the support shell 32 instead of the support shell 1 a and the end of the cover plate 30 which is firmly connected to the support shell 1 a in the drawing on the rear side 34 of the support shell 1 a to rest, preferably under spring tension of the cover plate 30. The cover plate 30 can be made of the same material as the support shells 1 and 1a, preferably made of steel.

The features described in the abstract, in the patent claims and in the description and apparent from the drawing can be essential for realizing the invention both individually and in any combination.
