Definitions
- the present invention relates to a reinforced concrete slab or - ceiling with arranged between the hollow bodies concrete webs and with a reinforcement layer over the hollow bodies and with a reinforcement layer under the hollow bodies. It further relates to a buoyancy-free hollow body for the production of such reinforced concrete hollow body panels or ceilings, which is designed as buoyancy-free, downwardly open and circumferentially closed container, in the ceiling wall vent holes are optionally provided, wherein the container has spacers. It also relates to a
- Reinforced concrete hollow slab or ceiling comprising said hollow bodies.
- a reinforced concrete hollow slab is known from EP 1 252403 A1.
- hollow body as described for example in the document DE 200 04 140 U1.
- Each reinforcement layer consists of two superimposed layers of parallel reinforcing bars, wherein the bars of a reinforcing layer with respect to those of the other layer are twisted by an angle of preferably 90 degrees.
- These reinforcements in conjunction with the pressure-resistant concrete, are intended to produce a bend-resistant plate / blanket capable of absorbing the local bending moments.
- a panel / ceiling is also exposed to internal, vertical shear forces, ie shear forces.
- the ability of a non-reinforced in the concrete webs hollow body plate / blanket for the removal of shear forces is severely limited due to the low computationally fixed concrete tensile strength and the cross-sectional weakening by the hollow body.
- the object is achieved in a generic plate characterized in that the concrete of at least one web tensile strength fibers and / or at least one steel strut, preferably a double-headed anchor having.
- the invention thus provides, in addition to the already known instrument of vertical reinforcement in the concrete ridge nodes, further instruments which can be combined with this vertical reinforcement or with one another in order to adapt the lateral force carrying capacity of the locally existing load.
- the object is also achieved in that it has a vertical reinforcement in or near a concrete ridge node, which is formed by hook monokopfanker (12).
- the zones under and over the hollow bodies and concrete webs which are reinforced anyway with reinforcing bars, preferably not provided with fibers. This is technically possible because the zone under the hollow bodies and concrete webs, the zone of the concrete webs and the zone above the hollow bodies and concrete webs in three phases in succession, but still "fresh in fresh", can be concreted.
- Double-headed anchor almost in the axis of the adjusting pressure diagonal in some concrete webs. - A -
- a truss-supporting system Under transverse force stress of the plate / ceiling, a truss-supporting system is formed, which has among other things inclined pressure struts.
- Such an inclined compression strut begins at the intersection of the horizontal reinforcement layer over the hollow bodies with the vertical in the concrete web node, and ends on
- the compression strut can form because of the compressive strength of the concrete.
- Concrete can not buckle sideways, so may be thin.
- Double-headed anchor almost in the axis of the adjusting draft diagonal in some concrete bridges.
- a truss-supporting system which has, among other things, inclined tension struts.
- Such an inclined tension strut preferably begins at the intersection of the horizontal reinforcement layer below the hollow bodies with the vertical in the concrete web node and ends preferably at the intersection of the horizontal reinforcing layer on the hollow bodies with the perpendicular in an adjacent
- This tie rod thus runs diagonally in the concrete bridge from bottom to top, but inclined against the pressure strut mentioned under 2, this crossing in the middle of the strut.
- the tension strut can form only because of the computationally difficult to apply, low tensile strength of the concrete, if approximately in the axis of the tension strut a tensile, sufficiently anchored at the ends component is installed, preferably a double-headed anchor or a hook-mono head anchor.
- hook monobloc anchor installed in concrete ridge node and / or in a concrete bridge.
- rods made of reinforced ribbed steel with ribbed surface the tensile force in the anchor below a, preferably as a flat cone, have head, as it double head anchor have two, and above for tensile force in the anchor have a hook, which installed a bar of the armor layer over surrounds the hollow bodies.
- the embodiment of arranging the vertical reinforcement in the concrete webs, knotting instead of or in addition to the vertical reinforcement in the concrete web, advantageously allows to reduce the horizontal spacing of the vertical reinforcing bars, where necessary, and thus to achieve an increased transverse force carrying capacity.
- a vertical reinforcing bar according to the invention is to be understood as meaning a single vertical reinforcing bar or a group of vertical reinforcing bars standing next to one another, which are sufficiently anchored in the concrete at the top and bottom, for example iron curved in the shape of a hat.
- shear reinforcements in the form of so-called shear allowances between the upper and lower horizontal reinforcing layers can be avoided with the invention. These are less stable than brackets or double-headed anchors. Usual push supplements with tied or welded reinforcing bars are also consuming to manufacture and interfere with the installation of spacers between the hollow bodies.
- the embodiment of the invention which uses hook mono-head anchors, offers the particular advantage of being even more economical than designs with double-headed anchors. Because a hook-mono head anchor is cheaper to manufacture and grants a faster installation, since it is hung only on a rod of the reinforcement layer on the hollow bodies and, against slippage during concreting, must be connected by means of rewiring with this.
- the use of fiber concrete is advantageous because it the splitting tensile strength of the building material and thus the Carrying capacity of the printed diagonals increases in shearing stress adjusting internal framework.
- Steel fibers are advantageously commercially available and can be procured at short notice. They are advantageously fully automatically produced inexpensively and also the introduction into the concrete is inexpensive. If the fibers are added according to an embodiment of the invention, only the concrete for the concrete webs, the amount of fibers required reduces cost.
- the buoyancy-free hollow body has a conical or truncated pyramid-shaped circumference, whose upper end forms a dome-like vault.
- This geometric shape has over the conical containers used in practice greater stability for receiving the vertical loads, z.
- weight of the upper reinforcement and fresh concrete in assembly work, reinforcement and concreting. When introducing concrete, this can be distributed quickly due to the aerodynamic shape.
- Due to the dome-like shape of the hollow body a statically favorable vault magnitude effect also arises in the region above the hollow body in the hardened concrete, if this area is loaded by vertical loads. becomes.
- At least three radially arranged ribs are provided on the hollow bodies as upper spacers, which are integrally formed on the dome-like vault. Since the buoyancy-free hollow body preferably made of recyclable plastic, the radially arranged ribs can be made together with the hollow body in one operation. This reduces the manufacturing costs and assembly times on the construction site. In addition, the otherwise accounts usual fastening means such as wire etc. for the spacers. The spacers also make it possible to use a particularly advantageous rollable reinforcement. As a result, the assembly time and thus the costs can be further reduced.
- the buoyancy-free hollow body preferably has an annular shoulder in the region between the conical or truncated pyramid-shaped circumference towards the dome-shaped arch. This allows the arrangement of several hollow body in the demand for a larger ceiling height.
- the upper hollow body is then adapted in its lower opening diameter to the diameter of the annular shoulder of the lower hollow body. Depending on the static requirements so ceilings of different heights can be created without major installation effort.
- the dome-like vault of the hollow body in cross section has approximately the shape of a half ellipse.
- the volume of air of the hollow body increases considerably, so that this circumstance leads not only to a significant concrete savings but also to a further reduction in weight of the entire reinforced concrete ceiling, which can be realized larger spans of the ceiling.
- a foot ring forms the lower end of the hollow body. This increases the stability of the hollow body during assembly and also increases its stability.
- Distanzianssbügel are distributed as lateral spacers to other hollow bodies evenly over the circumference of the hollow body, are arranged. They serve the simple and secure positioning and fixation of the raised hollow bodies on the lower reinforcement layer.
- the Distanzianssbügel are U-shaped and preferably have a catch. With a safety catch is achieved that the complex wiring of the hollow body eliminated with each other and thereby the assembly times can be additionally shortened.
- the molded in the dome-like vault spacers continue radially towards the periphery as a bead.
- Z. b. bottom edges are provided by stacking webs, in which stacked hollow bodies sit one above the other.
- stacking webs are arranged under the annular shoulder.
- the stack webs improve the ability of the hollow body to accommodate vertical loads.
- the object of the invention is finally solved particularly advantageous by a reinforced concrete hollow slab or blanket, both the inventive hollow body and the inventive Transverse force capacity increase by fiber concrete, and / or steel struts, preferably double-headed anchors, and / or vertical reinforcements used in at least one concrete web, since in this way all cost-reducing designs are implemented.
