Definitions

  • the invention relates to a prestressed plate element according to the preamble of claim 1 and a preferred use of such a plate element according to claim 13 and a production method for a plate element according to claim 14.
  • Preloaded plate elements thus also contain tensioning elements in addition to the "limp" reinforcing bars.
  • "limp" reinforcement can be reduced to a constructive minimum, e.g. for the absorption of parasitic, locally occurring constraining forces and as reinforcement against surface cracks, when the dead weight and the payload of the element are completely compensated by the deflection forces.
  • Necessary preloading devices are tension cables, sleeves surrounding the cables, injection materials which are inserted between sleeve and cable after tightening depending on the laying process, anchor heads, couplings, support aids for the sleeves and cables, and tensioning devices.
  • the mass of ceiling weight to be compensated by the deflecting forces of the tensioning cables is directly proportional to the applied tensioning force and thus to the cross section of tensioning cables used.
  • the tension cables are made of high-strength steel, which has a particularly high tensile strength.
  • the manufacture of the cables is therefore subject to strict qualitative specifications, with the result that the cost of the cable is many times higher than the cost of conventional "limp" reinforcing steel.
  • the use of the preload allows the bridging of larger spans while minimizing the ceiling thickness and thereby the ceiling own weight.
  • the preload allows better control of concrete cracking due to horizontal constriction.
  • Another advantage of prestressing is the minimized deformation of the ceiling, which is often the decisive criterion for ceiling thickness when designing concrete floors.
  • the use of prestressing can also optimize the construction time as the formwork of a prestressed ceiling can be removed sooner.
  • the publication AU 505 760 B2 discloses a plate member according to the preamble of claim 1. Its components may have a downwardly bulged area and be fabricated from concrete. These components are then arranged and fixed to each other at the construction site. For this purpose, clamping elements are used, which run along the side edges of the respective components.
  • the publication DE 12 22 643 B discloses a plate element which is prefabricated in a concrete factory.
  • the plate element contains in the plan view of its surface at least one hollow body region with hollow bodies contained therein.
  • clamping elements In the context of this application, the term "lattice-shaped" arrangement of clamping elements is to be understood as meaning a structure in which these elements intersect at one or different angles, which are not necessarily right.
  • the clamping elements do not have to be rectilinear, but can also be curved, for example in the case of geometrically demanding plate geometries, e.g. circular arc, parabolic, eight-shaped or similar be laid to meet the corresponding load case.
  • the invention is based on the assumption that clamping elements guided over hollow body regions allow only limited prestressing due to the reduced material. In addition, a geometric problem arises because the space for receiving these elements is severely limited. So far so far a laying was possible, therefore, the combination of hollow body areas and bias does not necessarily lead to improved performance of the plate member. By too high a bias in these areas, the plate element can even be damaged and thus made unusable.
  • An essential point of the present invention consists first of all in the particularly reinforced support strips which connect individual support areas of the plate element to one another. This makes possible a hybrid combination of hollow body regions and prestressed regions of a plate element, which enhances the optimizing effect of both reinforcements in a technical, economical and ecological manner.
  • the example of the "limp reinforced" flat cover known approach to use entire modules with hollow bodies to reduce a ceiling own weight can also be transferred to prestressed ceilings, in which compensated either only the own weight, or the entire loads by tensioning cable become.
  • the technical advantages of both methods can be combined and the weight reduction of the blanket can be increased compared to slackly reinforced, solid concrete floors or prestressed ceilings.
  • the loads acting on the vertical elements such as columns, walls and foundations of a supporting structure are thus additionally reduced.
  • the use of material on tensioning cables and anchor heads is optimized, especially since the additional weight of the ceiling, which is reduced by between 25% and 30%, directly influences the required tensioning cable cross-section directly.
  • the required concrete volume is reduced and the deformation of the ceiling is additionally minimized.
  • a planner has various options for arranging the cables. So he can choose a surface preload in which the cables are evenly distributed over the ceiling length and width. Another option is provided by the support strip bias, in which the cables are arranged in a concentrated manner in the zones running over the supports in orthogonally arranged bands. But it can also be a combination of both arrangements can be selected, in which in one direction surface, in the other one works in support strips.
  • a further reinforcement of the plate element according to the invention is achieved in that in the lateral view, the clamping elements are wavy laid in the plate member, and are supported on at least one latticework of rods with hollow bodies held therein, whose respective height is adapted to the waveform. Since the lattice derives the forces introduced by the clamping element past the cavities, they are protected from destruction. This is a hitherto unknown Spannelement Installation and thus bias across hollow body areas away possible.
  • a support strip preferably comprises at least one solid material region, via which loads introduced can be reduced.
  • laterally adjacent fields of the latticed structure form at least one elongated carrier strip with hollow body regions, which is arranged between two support strips.
  • additional clamping elements for reinforcing the plate element are preferably provided in the longitudinal direction of a support strip. These clamping elements need not necessarily run laterally of the strip. In particular, they can be arranged distributed over the width thereof or lie only in its middle region. These additional clamping elements can also be designed comparatively stronger than others.
  • a support strip may themselves be reinforced, e.g. have a larger cross-section or a tensile material stronger than the other clamping elements.
  • a support strip may comprise at least one hollow body region.
  • additional clamping elements may be provided within a support strip of solid material, while another support strip is reinforced only laterally and having hollow body portions.
  • additional clamping elements can be provided which are distributed over its width or even run in its middle. If these clamping elements overlap hollow body regions of the support strip, they are provided with a lower preload.
  • a weight reduction of the plate member can be achieved by supporting strips which extend in grid structure between the support strips.
  • any other structure may be provided which consists of rectilinear or curved clamping elements, which intersect at a certain or several different angles.
  • the bars of the latticework are arranged slightly obliquely with respect to a normal of the surface of the plate element. Such designed modules thus compensate for a caused by the hollow body local reduction of the transverse force capacity of the ceiling cross-section. In addition, these bars can record the possibly generated in the concrete by the bias voltage local parasitic voltages perpendicular to the ceiling plane.
  • Lateral strips of the hollow body areas can still be reinforced by the latticework has support rods which protrude in the longitudinal direction over a receiving area for hollow body, and over which the clamping elements are laid.
  • the lateral support can thereby still be improved by individual lattice works of rods are held with held therein hollow bodies to each other so that overlap their mutual support rods each other.
  • a reinforcement extending in the longitudinal direction over at least two latticeworks is created.
  • lattice structures may also be preferred for lattice structures to have receiving regions which do not contain hollow bodies and over which the clamping elements are laid. As a result, an extremely flexible reinforcement of the plate element is also possible over regions which contain hollow bodies but, despite existing surface or support strip prestressing, require additional reinforcement.
  • the plate element according to the invention should be used as a ceiling element, since just occurring there loads require a low weight and a high load capacity of the ceiling construction.
  • its use is not limited to this, because it can also be used in any other application form, where particularly lightweight and at the same time very stable elements are required. This is not only the case in housing and office (high) construction, but also includes in particular power plants, bridges, dams and the like. one.
  • An essential point of the inventive method consists in its simple feasibility both in the classical Ortbetonanassemble as well as in prefabricated Elements made in a precast concrete factory.
  • the application of this method is conceivable both for use with concrete of conventional composition and quality, as well as for concrete of alternative mixture and conception, such as lightweight concrete and fiber concrete.
  • Lattices with hollow bodies held therein are preferably delivered as modules.
  • modules are installed directly between the lower and upper flared reinforcement in the zones of the ceiling not occupied by the tensioning cables. If there is no loose reinforcement in the zones occupied by the modules, the modules are placed directly on spacers that rest on the formwork. This is advantageous in that the ceiling cross-section can be better exploited in favor of the modules due to the absence of the upper and / or lower flaccid reinforcement layers. Taking into account the required minimum lower and upper concrete cover of the modules, larger hollow bodies can be used as a result.
  • tension elements can additionally reinforce the plate element, which extend over hollow body regions. These elements need not have the basic tension of the surface or the support strips, but may be biased weaker. A flaccid reinforcement is then no longer absolutely necessary, so that a greater distance between modules and surfaces of the plate element can be used to accommodate the clamping elements.
  • the modules can serve as support for the pretensioning cables.
  • graduated size modules are selected according to the geometric shape of the tensioning cables and placed under the tensioning cables in the areas where the tensioning cables are located in the upper area of the ceiling section. This can be additional Occupy surfaces with modules and further optimize weight savings, as well as save conventional support aids. If necessary, the geometry of the modules used can be adapted to the conditions and specific requirements of the tensioning cables.
  • the at least one tensioning element is placed on support bars of the latticework, which protrude in the longitudinal direction over a receiving area for hollow body.
  • respective end regions of the latticework can be additionally reinforced, since there no hollow bodies come to rest.
  • the element 10 comprises hollow body regions 20 and supporting regions 30.
  • orthogonally arranged clamping elements 40 form a grid-shaped structure 50, the respective fields 51 of which are the regions 20 and 30 limit.
  • Laterally adjacent fields 51 form support strips 60, which connect the support areas 30 across fields 51 away from each other, these fields are designed to reinforce the support strip as solid material areas.
  • laterally adjacent fields 51 form rows of elongated carrier strips 80 with hollow body regions 20, which are surface-tensioned via the clamping elements 40.
  • Such a plate element 10 is preferably used as a ceiling element which is mounted in the support areas 30.
  • the solid support strips 60 provide sufficient stability for the intervening support strip 80 so that a light as well as sustainable ceiling element is created.
  • a simple and cost-effective production of the element 10 is ensured.
  • FIG. 2 shows the schematic structure of a novel plate member 10 'with support strip bias in a plan view of its surface 11'.
  • the element 10 'again comprises support and hollow body regions 20 and 30.
  • orthogonally extending clamping elements 40 form a grid-shaped structure 50 whose fields 51 delimit the regions 20 and 30.
  • the tension members 40 are reinforced, in this example, doubled.
  • the support strips 60 are thus reinforced so that they can also comprise hollow body portions, which make the element 10 'lighter.
  • carrier strips 80 can be provided with large-area hollow body regions 20 which extend vertically and horizontally between the support strips 60.
  • all here possible fields 51 are performed with hollow body portions 20, with such an element 10 'so that not only a weight but also a maximum carrying capacity is achieved.
  • the right angle laying the clamping elements 40 makes the simple and inexpensive production of the element 10 'possible.
  • FIG. 3 shows a side view of the first and second plate member 10, 10 'with a profile of a clamping element 40 via lattices 90 with held therein hollow bodies 21.
  • the size of the latticeworks 90 is chosen so that they specify the desired course of the clamping element 40.
  • the latticeworks are constructed of rods 91, whose example, approximately trapezoidal frame on the one hand a particularly high stability on the other causes a particularly high power dissipation of the bias of the clamping element 40 in the material inside.
  • the clamping element 40 rests on longitudinal bars 91 of the latticeworks 90, which extend perpendicular to the plane of the page.
  • rods 91 have a reinforcing effect corresponding to that of a reinforcement 100 and may even replace the reinforcement 100 under the circumstances to be described below.
  • the combination of grids 90 and clamping elements 40 makes a bias in hollow body portions 20 of the plate elements 10, 10 'of FIGS. 1 and 2 and thus a reinforcement of the element 10, 10 'possible.
  • FIG. 4 shows a grid according to the invention 90 with held therein hollow bodies 21 and projecting rods 92 which project beyond receiving areas 93 for the hollow body 21.
  • clamping element 40 may be laid at any desired location on, for example, the uppermost longitudinal bar 91 of the latticework 90. It is advantageous, however, to guide this over, for example, the uppermost support rod 92 of the latticework 90 at one or the other end of the latticework 90, since these ends are filled by solid material, which allows an even higher bias and thus gain.
  • FIG. 5 Finally, a combination of two latticeworks 90 overlapping the projecting bars 92 shows FIG. 4 , Due to this overlap, all the longitudinal bars 91 of both latticeworks 90 act like the correspondingly aligned reinforcements 100 in FIG FIG. 3 , At the same time, the overlapping bars 92 provide a more stable support for the tensioning cable 40 also shown there, when it is laid over these rods 92.
  • the plate element according to the invention is significantly more load-bearing and at the same time lighter than a known plate element.
  • the simple construction allows at the same time a cost-effective production. Due to its performance, it should preferably be used as a ceiling element that carries across wide areas.
