Definitions
- the invention relates to an arrangement for the stabilization of supporting structures for machines, plants, buildings and other structures.
- the proposed arrangement serves at the same time the stiffening of corresponding structures and their stabilization against vibrations, such as those caused by earthquakes.
- the arrangement of the invention serves to stabilize frame structures.
- dampers in particular viscous dampers
- a corresponding solution with a damper arranged diagonally in a frame construction is disclosed, for example, by WO 01/73238 A2.
- the presented solution has the disadvantage that it has to be very massively designed with regard to load changing between train and pressure, as is typical in practice, in particular also in the case of earthquakes, at the pressure loads on the damper or the fasteners the damper or given for the fasteners for construction risk of buckling low.
- This requirement of a massive design brings with the use of said solution relatively high costs.
- the damper does not contribute to the static stiffening of the support structure. Rather, for this purpose, as shown in FIG. 5 of the cited document, separate stiffening elements on the support structure, for example in other frames of a frame construction, arranged.
- the object of the invention is to provide a solution which allows an effective, yet cost-effective stabilization of support structures both from a static and a dynamic point of view.
- the arrangement according to the invention serves to stabilize supporting structures for technical objects, such as machines, plants, buildings or other structures.
- her support structures can be stabilized, which consist of support elements that support or horizontal Support beams are formed and / or form a frame construction.
- adjacent support elements by means of clamping elements, such as tension cables, tie rods or drawstrings, clamped together.
- clamping elements such as tension cables, tie rods or drawstrings
- the clamping elements which clamp the support elements together and the one or more arranged between them additional elements form according to the invention a stabilization unit.
- the clamping elements and the one or more additional elements are connected in series with each other.
- a bias voltage for the clamping elements is generated by means of additional elements.
- the stabilization unit forms a static reinforcement for the support structure, which acts load-bearing even under strong dynamic load, for example, by vibrations, such as those caused by earthquakes. Due to the prestressing of the ropes or drawstrings, no pressure forces are generated in the stabilization unit when seismic action occurs.
- the damping and the spring stiffness of the stabilization unit formed by the arrangement according to the invention thus also act in an advantageous manner even with alternating stresses (change between train and pressure), since only the static tensile force is increased or reduced by earthquake forces.
- Embodiment of the invention to act helical compression springs The coupling between a clamping element and an additional element takes place via a force applied to the pressure force of the helical compression spring or springs coupling element which deflects this pressure force and transmits as a tensile force on the clamping element.
- the spring or the springs of the additional element may also be formed as a tension spring, wherein the coupling between a clamping element and this additional element is then given by a coupling element, via which the tensile force acting on it the tension spring or tension springs is transmitted almost directly to the clamping element.
- the stabilization unit can connect the support elements of a frame construction to one another.
- a diagonal bracing for the frame of the frame construction is formed by the stabilization unit, wherein the stabilization unit preferably connects two corner points of the frame to one another.
- the arrangement according to the invention can also be designed so that it is at the adjacent support elements, which are interconnected by means of a stabilization unit to parts of support structures of various technical objects, ie, for example, supports the frame structures of two adjacent buildings.
- Fig. 1 is a schematic representation of a first embodiment of the inventive arrangement
- FIGS. 9 and 10 each show a schematic representation of possible embodiments of the arrangement according to the invention. These are opposed by arrangements which are also shown schematically in FIGS. 9 and 10 and which are known from the prior art on the one hand for the static stabilization of structures and on the other hand for their protection against earthquake-induced vibrations.
- FIGS. 9 and 10 schematically illustrates a support structure 7 designed as a frame construction 10, which is statically stabilized by diagonally arranged stiffening elements 11, 11 ', for example corresponding struts.
- Fig. 10 shows schematically an arrangement for the dynamic stabilization of a building or the like, as it is known from the cited prior art.
- a preferably viscous or viscoelastic damping element 12 is installed in a support structure 7 which is likewise designed as a frame construction 10 in a substantially diagonal arrangement.
- a damping element 12 no static stiffening effect is given.
- a very massive design of the damping element 12 is necessary.
- the illustrated damping element 12 does not contribute, so that separate stiffening elements are provided for this purpose.
- the solution according to the invention as shown in FIGS.
- the arrangement also has a very simple design, which makes it on the one hand cost in manufacturing and installation and by the other hand, it is very easy adaptable to different circumstances and requirements and, for example, in existing structures or support systems for machines can be retrofitted. Both variants, the basic principle of the invention is common.
- clamping elements 1, 1 ' such as drawstrings or tie rods, between which a viscoelastic additional element 2, 2', namely parallel a spring 3, 3 'and a viscous or viscoelastic damper 4, are arranged, wherein the clamping elements 1, 1 'are biased by means of the additional elements 2, 2'.
- the viscoelastic additional element 2, 2 'arranged between the tension cables or the tension rods 1, 1' is as shown in FIG The figures seen coupled in different ways.
- the additional element 2 and the clamping elements 1, 1 'by coupling elements 5, 6 are interconnected, which transmit the tensile force of the tension spring on the clamping elements quasi-immediate.
- the coupling elements 5 ', 6' in the embodiment of FIG. 2 kraftumlenkend by the compressive force with which they are acted upon by the compression spring 3 ', transmitted as a tensile force on the clamping elements 1, V, which the bias of Clamping elements 1, 1 'determined.
- the reference numerals 3 and 3 'as well as the reference 4 optionally also refer to groups of parallel arranged springs 3, 3' or damper 4, which in practice are corresponding groups with suitable, matched geometries becomes.
- the arrangement for stabilizing a support structure 7, T serving arrangement is such that between the, adjacent support elements 8, 9, 9 ', 10, 10' of the support structure 7, T tensioning clamping elements 1, 1 'at least one viscoelastic additional element. 2 , 2 'and connected in series with them to form a stabilizing unit. This of course leaves open the possibility that several viscoelastic additional elements 2, 2 'are arranged within a stabilization unit.
- FIGS. 3 to 5 correspond to the respective design of the components of the inventive arrangement. namely, for example, size and thickness of the drawstrings 1, 1, 1 ", biasing force or spring constant of the spring or springs 3, 3 'of the viscoelastic additional element 2, 2' or the dimensioning of its damper 4, are dependent on the particular circumstances, such as type of support structure 7, T and installation location, and the expected loads occurring, depending on the factors mentioned different options or requirements for the type and Way of installing the assembly and its connection to the main system, or the support structures 7, 7 ', given.
- FIGS. 6 to 8 show two possibilities of a diagonal connection of the arrangement according to the invention with the support elements 8, 9, 9 'of a support structure 7 in the form of a frame structure 10, which differ in the choice or location of the connection points between support structure 7 and stabilization unit. While the stabilization unit formed by the drawstrings and the additional elements 2, 2 'according to FIG. 6 connects two corner points of the frame of a frame construction 10, it is shown in FIG. 7 on the longitudinal sides of two adjoining and interconnected support elements 8, 9 of the support structure 7 tethered.
- the arrangement according to the invention is characterized by the following advantages:
- the stabilization unit formed from the combination of tensioning elements and viscoelastic (viscoelastic) additional element (s) can act in the immediate vicinity of the frame nodes and it is necessary in the Usually no further special stiffening, as in the known from the prior art solutions.
- the seismic safety of the structure is significantly improved if properly designed.
- the arrangement can be used in new buildings or for seismic upgrading existing buildings.
- Stiffening of supporting structures can be achieved. -
- the arrangement or the entire system is dynamically easy to model. In real use, additional static loads occur, which are often in equilibrium.
- the arrangement is easy to install - there are usually no extensive additional measures required.
- the existing support system or the support structure is not changed in the rule, but only supplemented by additional stiffness and damping.
- the arrangement is virtually maintenance and wear-free. - A standardization, for example, for different preload forces, is conceivable.
- the arrangement is very versatile.
- clampping element tensioning cable, tie rod, strap or drawstring
