Embodiment Construction

[0042] figure 1 A schematic structure of a plate element 10 according to the invention with planar prestressing is shown in plan view of the surface 11 thereof. In this case the element 10 comprises a hollow element area 20 and a support area 30 . In this embodiment, the vertically arranged compression elements 40 form a grid-like structure 50 , the respective domains 51 of which define the areas 20 and 30 . The laterally adjoining domains 51 form support strips 60 connecting the support regions 30 to one another at the domains 51 , wherein the domains are embodied as regions of solid material for reinforcing the support strips. In contrast, laterally adjoining domains 51 form slightly longer carrier strips 80 with hollow element regions 20 , which are pressurized planarly via the pressing elements 40 . The plate element 10 is preferably used as a ceiling element installed in the support area 30 . With regard to planar pre-stressing via the grid system 50, the solid materia...

Abstract

The invention relates to a prestressed slab element (10), in particular a concrete slab element, manufactured according to the in-situ concrete method or prefabricated in a concrete precasting plant which in top view of its surface (11) comprises at least one hollow element region (20) with hollow elements (21) contained therein and at least one support region (30) for supporting or holding the slab element (10) without hollow elements (21), as well as stressing elements (40) for reinforcing the slab element (10), which each are installed through the slab element (10) and form a lattice-shaped structure (50), wherein individual fields (51) of this structure (50) establish a support or hollow element region (20, 30), and laterally adjoining fields (51) of the lattice-shaped structure (50) form at least one longish support strip (60) which joins individual support regions (30); with one another and which is embodied in a reinforced manner, characterized by stressing elements (40), whichin a lateral view of the slab element (10) are installed in the slab element (10) wave-like and which support themselves on at least one lattice system (90) of bars (91) with hollow elements (21) held therein whose respective height is adapted to the wave shape.

Description

technical field [0001] The invention relates to a prestressed plate element according to the preamble of claim 1 , a preferred use of this plate element according to claim 14 , and a method of manufacturing a plate element according to claim 15 . Background technique [0002] It is already known to produce particularly thin plate elements made of concrete in order to produce more preferably flat ceiling structures based on hollow elements embedded therein. The plate elements described here are so-called "stress-free reinforcement" elements, the reinforcement of which consists of vertically arranged stiffeners which absorb the tension forces arising in the concrete. The structural efficiency of this lightweight construction technology allows, for example, to construct thin but long-spanning flat ceiling structures with simultaneous resource efficiency. Depending on the diameter and geometry of the hollow elements, embodiments with ceiling thicknesses of about 20 cm are feasi...
