Definitions
- Reinforcement body for a ribbed ceiling made of cast concrete
- the invention relates to a reinforcement body for a rib ceiling made of cast concrete, with at least one displacement body arranged between a basic reinforcement and a distributor reinforcement, in particular consisting of foam, which adjoins cavities for forming the stiffening ribs and by means of the basic reinforcement with the distributor reinforcement at a selectable distance from a dimensionally stable unit connecting web wires is fixed immovably between the reinforcements, additional shear reinforcement elements being arranged in the rib cavities in accordance with the structural requirements of the ribbed ceiling.
- the object of the invention is to further develop the reinforcement body in such a way that it can be prefabricated in the manufacturing plant, so that it facilitates the construction of a ribbed ceiling from several reinforcement bodies at the construction site and allows larger spans without the need for assembly.
- the reinforcement body is characterized in that each displacement body is part of an independent lattice body with a basic reinforcement part and a distribution reinforcement and that the lattice body is arranged on a basic reinforcement, which together with the basic reinforcement part of the lattice body and parts of the shear reinforcement elements into one Element plate made of cast concrete is embedded, and wherein on the distributor reinforcement of the lattice body or at least one of a plurality of lattice bodies, a concrete upper flange running parallel to the rib cavities and having a selectable length, width and height is arranged in the center.
- the reinforcement body is constructed from mechanically prefabricated lattice bodies. can, the number of which is chosen depending on the requirements, so that a modular structure is possible.
- the use of prefabricated lattice bodies ensures extremely rational production.
- the rib cavities are in each case reinforced with a lattice girder arranged on the base reinforcement, which has an upper chord, two lower chords and diagonal wires between the upper chord and the lower chords that connect them to one another and one to to the distribution reinforcement of the lattice body or the lattice body has sufficient or smaller height. In this way, reinforcement of high strength is easily achieved.
- the basic reinforcement consists of a reinforcement mesh mat that has longitudinal and transverse wires that are perpendicular to one another and welded to one another.
- the width of the upper concrete belts is smaller than the width of the respective lattice body, preferably half of the lattice body width.
- each lattice body according to the invention has a rectangular base area and the rib cavities run parallel to the longitudinal extension of the lattice body. All shear reinforcement elements and / or each lattice body can expediently be firmly connected to the basic reinforcement.
- the reinforcement body has two lattice bodies 1 with a preferably rectangular base area, which are arranged on a base reinforcement 2 in such a way that they laterally project beyond the two lattice bodies 1.
- the basic reinforcement 2 preferably consists of a reinforcing mesh mat made of perpendicular and mutually welded longitudinal and transverse wires, the wire diameter as well as the longitudinal wire and transverse wire spacing corresponding to the static requirements of the loading reinforcement elements are selected.
- the length of the basic reinforcement 2 corresponds to the length of the lattice body 1.
- Each lattice body 1 has a basic reinforcement part 3 and a distributor reinforcement 4, which are expediently flush on all sides.
- the basic reinforcement part 3 and the distributor reinforcement 4 consist of reinforcement mesh mats, each of which is formed from longitudinal and transverse wires that are welded to one another and welded to one another, the dimensions of the reinforcement mesh mats being selected in accordance with the structural requirements for the reinforcement body.
- the basic reinforcement part 3 and the distributor reinforcement 4 are connected to one another by web wires 5, which run between the correspondingly aligned longitudinal wires of the basic reinforcement part 3 and the distributor reinforcement 4 and are welded to them.
- a connection of appropriately aligned transverse wires of the basic reinforcement part 3 and the distributor reinforcement 4 with the aid of the web wires 5 is also possible within the scope of the invention.
- the distance between the basic reinforcement part 3 and the distributor reinforcement 4 and thus the length of the web wires 5 can be freely selected and can be adapted to the height of the ceiling slab to be produced using the reinforcement body.
- a displacement body 6 of a predetermined height Arranged between the basic reinforcement part 3 and the distributor reinforcement 4 at a predetermined distance from them is a displacement body 6 of a predetermined height, which expediently consists of light material, for example polystyrene, and makes it possible to save concrete in the ribbed roof to be produced and thus to save its weight to reduce.
- the web wires 5 penetrate the displacement body 6 and are alternately arranged in opposite directions at an angle to one another in the form of a framework. This arrangement enables the web wires 5 to fix the displacement body 6 precisely in its position in the lattice body 1 and also to absorb shear forces acting on the lattice body 1 parallel and perpendicular to the longitudinal wires of the basic reinforcement part 3 and the distributor reinforcement 4.
- the web wires 5 in the lattice body 1 which have an immovable and fixed position of the displacement body 6 relative to the basic reinforcement part 3 and the distributor reinforcement 4 ensure and are able to absorb thrust. It is possible, for example, to arrange all the bridge wires between two assigned longitudinal wires of the basic reinforcement part and the distribution reinforcement in the same direction, and to arrange all bridge wires between adjacent, assigned longitudinal wires also in the same direction, but with the opposite direction to the first mentioned bridge wire family , so that a herringbone-like structure is created. This applies in the same way if the bridge wires run between assigned cross wires.
- the lattice bodies 1 are arranged on the base reinforcement 2 with a lateral spacing from one another in such a way that a central rib cavity 7 with a predetermined width, parallel to the longitudinal extension of the lattice bodies 1, is created.
- the lateral protrusion of the basic reinforcement 2 beyond the lattice body 1 also results in lateral rib cavities 7 ′ running parallel to the longitudinal extension of the lattice body 1.
- the rib cavities 7, 7 ' are filled with in-situ concrete when the reinforcement body is used to produce a rib ceiling and thus form the stiffening ribs of the rib ceiling.
- the width of the rib cavities 7, 7 'must therefore be selected in accordance with the static requirements that are placed on the stiffening ribs of the rib ceiling to be produced.
- the width of the lateral protrusions and thus the width of the lateral rib cavities 7 ' is additionally determined by the fact that the joint between abutting reinforcement bodies can be covered with a joint reinforcement mat which is only to be inserted subsequently when the reinforcement bodies are installed on the construction site.
- Each lattice girder 8, 8 ' consists of an upper chord 9, two lower chords 10 and diagonal between the upper chord 9 and the lower chords 10 extending and interconnecting infill wires 11.
- the dimensions of the upper chord 9, the lower chords 10 and the infill wires 11 are in accordance with the static requirements for the Reinforcement of the rib cavities 7, 7 'can be selected.
- the height of the lattice girders 8, 8 ' is selected such that the top chords 9 of all lattice girders 8, 8' are each aligned with the distribution reinforcements 4 of the lattice body 1; however, it can also be smaller.
- the lattice girders 8, 8 ' in particular in the area of the lower chords 10, with additional reinforcement elements, for example in the form of individual bars.
- the lattice girders 8, 8 'and the lattice body 1 each stand on the basic reinforcement 2 and are only shown at a distance in the figure for reasons of simplicity.
- the lower chords 10 of the lattice girders 8, 8 'and the basic reinforcements 3 of the lattice bodies 1 can be fastened with the aid of suitable fastening elements, such as e.g.
- Brackets or solder wire are firmly connected to the corresponding wires of the basic reinforcement 2, so that slipping of the lattice girders 8, 8 'and the lattice body 1 is avoided during further processing of the reinforcement body.
- the reinforcement body is provided with an element plate 12 made of concrete, the concrete layer having to completely embed the basic reinforcement 2, the basic reinforcements 3 of the lattice body 1 and the lower chords 10 of the lattice girders 8, 8 '.
- the base reinforcement 2, the lattice body 1 and the lattice girders 8, 8 ' are usually first positioned in a formwork frame and then the element plate 12 is cast.
- the element plate 12 is cast.
- each lattice body 1 there is a concrete upper flange 13 running parallel to the rib cavities 7, 7 '. brings, the length, width and height are freely selectable, the width is smaller than the width of the grid body 1 and is expediently half the width of the grid body 1.
- the concrete upper chords 13 additionally stiffen the reinforcement body and, when building a ribbed ceiling with the aid of the reinforcement body according to the invention, enable a substantial increase in the assembly support width and thus a saving in assembly supports.
- lateral formwork strips 14 and formwork strips are arranged on the end faces of the distributor reinforcement 4.
- the formwork strips 14 are comb-like, so that they reach into the mesh of the distributor reinforcement 4 and are fixed in position by the distributor reinforcement 4.
- the formwork strips 14 extend to the upper cover surface of the displacer 6 and thus limit the concrete upper flange 13 laterally.
- a very wide reinforcement body can have three or more lattice bodies, each between adjacent ones Lattice bodies a central rib cavity is predetermined, which is reinforced with a lattice girder.
- each grille body with a concrete upper belt; however, it should be ensured that the distribution of the concrete top chords is symmetrical over the entire reinforcement body.
- the rib cavities can also be reinforced by other shear reinforcement elements, such as shear reinforcement stirrups.
- the basic reinforcement can also consist of individual appropriately arranged reinforcement bars within the scope of the invention.
