Definitions

  • the present invention relates to a reinforced concrete component of a building, a method for the construction of such a concrete component and individual components as components of the concrete component.
  • Highly loaded, strong-rated concrete components such as concrete walls of high-rise buildings with continuous reinforcement over all floors, are usually produced at the location of the building or the high-rise building by means of local formwork.
  • the production of the necessary formwork construction and the appropriate concreting on site is time consuming and costly.
  • a method is accordingly provided for erecting a reinforced concrete component of a structure, in particular an upright, reinforced concrete wall, wherein the concrete component is composed of several reinforced individual components.
  • connection reinforcement elements are regularly elongated, in particular rod-shaped, for example, as conventional reinforcing steel rods.
  • This single component is preferably prefabricated as precast concrete, preferably in a corresponding precast plant. In principle, however, the training as Ortbetonbauteil is conceivable with appropriate concreting at the place of construction of the concrete component. This particular, if this single component serves as the lowest component of the concrete component to be built, such as in an upright concrete wall.
  • precast concrete element is at least one further reinforced individual component of the concrete component to be produced.
  • this further single component holes are introduced into this by means of appropriate formwork. These holes arranged on one component side or ending there are adapted to the abovementioned first individual component or the connecting reinforcement elements of the first individual component. This is such that its connection reinforcement elements can each be inserted into the respective holes of the further individual component or fit into it.
  • a connection reinforcement element is preferably assigned in each case to a hole.
  • the two individual components are otherwise reinforced in the usual way, i. provided in the production with per se known reinforcement (reinforcement mats, reinforcing bars or the like). Conveniently, they are formed as otherwise conventional reinforced concrete parts. Naturally, however, it is also conceivable, for example, to use other reinforcing materials instead of steel reinforcements for reinforcement of the respective individual component.
  • connection reinforcement elements of a single component (naturally - or partially - only their lying outside the respective individual component sections) come to rest in the holes of the other component.
  • one of the individual components is suitably moved toward the respective other individual component. If, for example, one of the two individual components is already at the location of the later concrete component or already arranged or installed at its final destination in the later concrete component, but the other is not, the latter can - for example by means of a crane or the like - the already installed Individual component can be approximated or guided to this under "threading" of the respective connection reinforcement elements in the respectively associated holes.
  • connection reinforcement elements are in the holes
  • they are filled with a preferably cement-bonded grout.
  • the grout should have the highest possible flowability, a fast strength development and a high final strength.
  • This grout then provides in the cured state for a particular frictional bond between the respective hole walls of a single component and the associated hole or arranged in the respective hole connecting reinforcement element.
  • connection reinforcement elements are already in the holes, but at the same time a narrow gap remains between the two individual components.
  • This joint will later be filled with bonding compound, usually also with preferably cementitious grout.
  • connection reinforcement elements are in the holes.
  • this filling of the holes only in the assembled state of the individual components or when both individual components are already in their final position in the concrete component to be produced and accordingly the connection reinforcement elements are already arranged in the holes.
  • the holes would still need to be sufficiently accessible at this time. This prerequisite is at least theoretically possibly to be met if between the two individual components in the manner described above nor the later to be filled with bonding compound gap.
  • the concrete component to be erected will generally have a plurality of, in particular, identical individual components, in which the connection reinforcement elements described in each case protrude on one component side, but at the same time the described holes are arranged on another component side.
  • these component sides can be opposing sides of the respective individual component, in particular in the case of cuboidal individual components.
  • Each connection reinforcing element of such a component is assigned a corresponding hole on the opposite side of the component.
  • At least the protruding from the one side portions of the connecting reinforcement elements of the same are each arranged in such a way that they are in each case aligned with the respectively associated, arranged on the opposite side of the component holes.
  • the corresponding longitudinal center axis of the respective hole is aligned with the longitudinal central axis of the respective protruding portion of the respective connecting reinforcement element, in particular insofar as it is a rod-shaped reinforcing elements and correspondingly elongated holes.
  • an upright, heavily reinforced concrete wall of a structure in the manner described above has a plurality of stacked (vertically extending) single wall components.
  • the connecting reinforcement elements would regularly protrude from the respective lower sides of the single-wall components, and the holes would be assigned to the respective upper sides of the individual-wall components or introduced into these.
  • the lowest individual component of the concrete wall could be expediently designed as Ort researcheil with arranged on its upper side holes. It can be a (vertical) single wall component or the foundation of the concrete wall. In this single component, which is expediently, but of course not necessarily, prefabricated as in-situ concrete part, there are regularly unnecessary from the bottom underside, adapted to corresponding holes of one of the other aforementioned individual wall components connection reinforcement elements.
  • the single wall components are mounted one after the other from bottom to top.
  • each further above to be arranged individual component lowered to the already installed at the destination or located in the concrete wall, each directly below this arranged individual component. This is usually done by means of a crane.
  • elongate reinforcing elements for forming an overlapping joint are introduced into the individual component which has the holes, in particular during its production adjacent to the holes.
  • These reinforcing elements for forming an overlapping joint are positioned in this case, namely as a rule adjacent to the holes, in particular in addition to these, that they form an overlapping joint in the mounted state of the two individual components with the connection reinforcement elements then arranged in the filled holes.
  • the terminal reinforcing elements disposed in the holes and the reinforcing elements for forming the lap joint are juxtaposed and overlapped in the lap joint area.
  • connection reinforcement elements of a single component on the one hand and the reinforcing elements for forming the overlap joint of the other individual component on the other hand, at least in the region of the overlap joint be rod-like.
  • said reinforcing elements in this area run parallel or at least approximately parallel to one another.
  • the reinforcing elements for forming the overlapping joint may also be the connection reinforcing elements which partially protrude from the individual component and partly run in this connection element. In this case, they would be in the interior of the single component simply continue to be led into the overlapping joint area. This is particularly easy to implement when the connecting reinforcement elements are elongated reinforcing bars.
  • the holes are introduced into this during the production or the concreting of the corresponding individual component.
  • a multi-part formwork is used for each hole.
  • the formwork has a flexible, preferably elastic, thin formwork skin.
  • the formwork skin defines the contour of the later hole. It can for example consist of rigid PVC or sheet steel.
  • the filler protrudes laterally from the individual component to be concreted or projects beyond the corresponding (later) component side to the outside, so that it can be easily gripped by a worker after the concrete has hardened.
  • the filler is then first pulled out of the hole.
  • its formwork stabilizing effect continues and the formwork peels off from the corresponding, adjacent to this Betonlochwandung or can be easily solved by this and pulled out of the hole.
  • the outside of which is smooth-walled at least in the areas which rest on the formwork skin. Conveniently, the entire outside is smooth.
  • the packing shape is preferably substantially cylindrical, at least the part which is located in the hole.
  • the formwork skin of the formwork is prestressed in the position fixed by the filling body.
  • the elastic force or the spring force of the formwork skin is preferably to be designed in such a way that it can then overcome the adhesion of the perforated wall concrete to the formwork surface. This allows the formwork to be removed from the hole with very little effort.
  • FIG. 1 For example, a single component 10 made of reinforced concrete is shown. In the present case, this is a wall component of a vertical or upright reinforced concrete wall to be erected. In the present case, the individual component 10 is a prefabricated component and has already been prefabricated, for example in a corresponding precast component factory.
  • connection reinforcement elements 18 in this case connecting reinforcing bars made of reinforced concrete.
  • connection reinforcement element 18 of the individual component 10 is assigned a respective elongate hole directed into the component interior on the component upper side 12 whose longitudinal center axis is aligned with the longitudinal center axis of the outer section 18a of the associated connection reinforcement element 18 ,
  • the reinforcing rod 18 or its inner section 18b is guided in each case in the interior of the individual component 10 essentially up to its upper side 12. In this case, it runs from the bottom upwards slightly obliquely to the central axis of the single component 10 or between the portion 18a of the connecting reinforcement element 18 and the hole 14 resulting alignment line, so that he does not in each case in the upper component area with the respective, the corresponding reinforcing rod portion 18a associated hole 14 is aligned, but immediately adjacent to the hole 14 extends substantially to the top 12.
  • upper individual component 10 can be connected to the further, lower individual component 10 'by the individual component 10 from above to the already installed at the location of the concrete wall to be built, lower individual component 10' approximated or lowered on this or in the same direction.
  • the connecting reinforcement bars 18 of the individual component 10 are inserted or threaded into the corresponding holes 14 'of the individual component 10' until they come to lie or are arranged in the holes 14 '.
  • the lowering is therefore carried out as part of the assembly at the site of the later concrete wall, for example by means of a crane.
  • the holes 14 'of the lower individual component 10' have already been filled with potting compound 20, namely in the present case with cement-bonded grout. Due to the weight of the individual component 10 to be lowered or by the connection reinforcements 18, the grouting mortar 20 in the respective hole 14 'is partially displaced outwards / upwards. After hardening of the grouting mortar 20, a stable bond is then created between the respective connecting reinforcement elements 18 and the holes 14 'or the corresponding hole walls.
  • connection reinforcement elements 18 are indeed already in the holes 14 ', but that at the same time a narrow gap 21 between the two individual components 10, 10' remains.
  • This joint 21 is later filled with bonding compound, in this case also with cement-bonded grout.
  • the joint 21 serves for the additional connection of the two individual components 10, 10 '. In the present case, it has a thickness or thickness of approximately 20 mm. But the gap can also be made significantly stronger.
  • the reinforcing bar 18 'or the reinforcing bar section 18b' of the individual component 10 'and the connecting reinforcing bar 18 or the connecting bar section 18a of the individual component 10 thus form a so-called lap joint, i. they are over a certain (Überêtungs surge-) length 28 ', namely in the Sprintmannsdorf Kunststoff, juxtaposed or overlap there.
  • reinforcing bar 18b ' is the inner portion of the connecting reinforcing bar 18' of the individual component 10 ', namely in the present case around the upper portion thereof.
  • reinforcing rod 18b ' may alternatively also be provided to form the reinforcing rod 18b 'as a separate reinforcing element, which therefore does not simultaneously form part of the connecting reinforcement 18' or forms it.
  • the individual component 10 ' insofar as it is the lowest component of the concrete wall to be erected, may, moreover, be prefabricated in principle as a finished part, but alternatively also as a corresponding in-situ concrete component, before the individual component 10 is mounted.
  • the formwork 22 is designed in several parts and has a formwork skin 24, which ultimately defines the contour of the later hole 14.
  • the formwork skin 24 is formed of thin, flexible, elastic material, in particular plastic material.
  • the formwork skin 24 encloses a cavity 25, in which a separate, movable filler body 26 is inserted.
  • the filler 26 is formed dimensionally stable.
  • the outside of the filling body 26 is formed such that it at least partially rests against the inside of the formwork skin 24 and this stabilized as soon as the viscous concrete pushes against the outside of the formwork skin 24 within the context of the concrete component of the individual component 10.
  • the filler 26 is pulled from above from the hole 14, so that the formwork skin 24 solves almost independently due to their elasticity or spring force with decreasing back pressure by the packing 26 of the concrete wall of the respective hole 14, cf. ( Fig. 3b), 4b )). Then it can easily be pulled out so that the finished hole 14 remains ( Fig. 3c), 4c )).
  • the formwork skin 24 is even biased in the fixed by the filler body 26 position.
  • the bias is chosen such that the spring force of the elastic Formwork skin is sufficient to overcome the adhesion forces of the concrete or the hole wall. As a result, the formwork skin 24 can be removed from the hole 14 with even less effort.
  • FIGS. 3a) - b) or 4 a) - b) shown formwork 22 with the contour of the formwork skin 24 shown there for example, in the FIGS. 5 a) - b) shown formwork 22 'are used there with formwork skin contour 24'.
