  • Another approach provides to position the rod-shaped tensile reinforcement element to the building component before the casting of the building component suitable and then at least partially cast in the production of the building component.
  • This approach makes it possible to absorb higher tensile forces, but it does - if the elements concerned For example, to be provided on a building exterior - regularly to a projection at least of parts of the relevant tensile force-reinforcing element, which in particular the placement of a scaffold much more difficult and partially - even in cramped construction site conditions - even impossible.
  • the invention has for its object to further develop a formwork device of the type mentioned above or a method of the type mentioned in that the subsequent setting of a Switzerlandkraftbewehrungselements on a cast building component without the introduction of holes and without respect to the component protruding elements is made possible.
  • Another object of the present invention is to provide a thermal insulation component between two structural members with integrated tensile reinforcement elements which also enables the subsequent fixing of its tensile reinforcement member to the cast building component without the introduction of bores and without elements projecting relative to the building component.
  • a formwork device for creating a recess when casting a building component, in particular a building ceiling to be created from in-situ concrete, for connecting a rod-shaped tensile reinforcement element to the building component, characterized in that the formwork device at least one formwork element for forming the recess for the reinforcing element to be connected and at least one Having anchoring element, and that the anchoring element is formed so that it can be produced by this a positive connection between the building component and a recoverable and / or settable filler can be introduced into the recess.

  • the tensile reinforcement element according to the language of the present description are, in particular, tie rods of an Isokorb® element from the Applicant's company.
  • the shuttering device according to the invention is used to provide during casting of the component a recess in which the tensile reinforcement element is subsequently fixed by it with its free, the Building component associated end is inserted into the recess and then by filling the recess with a hardening and / or settable filler.
  • the formwork device not only has a formwork element for forming the recess for the reinforcement element to be connected, but also an anchoring element which is designed such that it can produce a form-locking connection between the building component and the filler.
  • This interlocking connection advantageously ensures that the filler is suitable for transferring unrestricted further the tensile forces transmitted to it by the tensile reinforcement element onto the building component surrounding it.
  • the anchoring element for producing the positive connection between the building component and the curable and / or settable filler which can be introduced into the recess at least partially into that of the formwork element projecting recess protrudes, the positive connection is thus made directly in the recess.
  • this may for example consist of a cement-containing, possibly fiber-reinforced construction material such as concrete, especially high-strength or ultra-high-strength concrete or high-strength or ultra-high-strength mortar or from a synthetic resin mixture, a reaction resin or like.
  • the main load case in the tensile force transmission is that the tensile reinforcement element is installed extending in the horizontal direction and that the tensile forces act first of all especially in this horizontal direction, so the form-fitting must be designed accordingly so that he prevents these horizontal movements.
  • the risk that the tensile reinforcement elements are lifted upwards ie in the direction of the upper side of the building component.
  • the anchoring element provides a positive connection not only in the horizontal direction, but also in the vertical direction, thus ensuring a vertical fuse.
  • the anchoring element in order to provide the anchoring element with the desired effects, it is also expedient for the anchoring element to protrude at least partially from the recess in the area of the building part surrounding the recess, that is to say that a building component-side positive connection is also provided.
  • the anchoring element at least partially traverses the shuttering element and thus extends from the side facing the recess of the shuttering element on the side facing away from the recess side of the shuttering element.
  • the anchoring element is designed as a lost anchoring element and is provided that it after the creation of the recess by means of the shuttering device permanently in the building component remains to produce thereby the positive connection between the building component and the insertable into the recess filler. Only by the retention of the anchoring element in the recess, the positive connection with the filler can be achieved and maintained until the load case.
  • the shuttering element is particularly recommended that this is removable after the creation of the recess and before the connection of the reinforcing element of the recess.
  • the filler ie in particular the concrete to be filled into the recess, can not only durably engage the anchoring element in a form-fitting manner, but the filler also comes into direct contact with the building component, ie in particular with the (hardened) in-situ concrete of the building component.
  • the shuttering element in terms of durability, durability, etc.
  • the formwork element is designed as simple as possible, for which purpose, for example, shell-shaped or box-shaped and may consist of plastic and / or metal.
  • This can be made thin-walled in film or sheet thickness, preferably of less than one millimeter and in particular of a few micrometers, so that overall the manufacturing costs can be very low. That is, the shuttering element itself - except when casting the building component - do not perform any supporting function, but it may be thin-walled and designed to be optimized in terms of easier removability after curing of the building component.
  • the formwork element in the building component is arranged essentially flush with its top side and front side in order to form the recess adjacent to the top side and front side of the building component. In this case, then extends to be connected to the recess reinforcing element in the horizontal direction of the recess through the end face of the building component to the outside.
  • the formwork element is designed so that it is removable in the direction of the top of the building component and / or in the direction of the intended course of the element to be connected reinforcing element.
  • the anchoring element it is particularly advantageous if this is designed as a reinforcing bar.
  • Reinforcing bars not only have proven and approved material properties with regard to use in existing concrete building components, but they also have the desired static capabilities, since the purpose of the anchoring element is the positive connection with the filler in the recess, the the transmitted via the reinforcing element in the filler tensile forces can continue to transfer to the building component.
  • the anchoring element in the form of a reinforcing rod, can advantageously be designed such that it functions as a common anchoring element for two or more shuttering elements or devices adjacent to one another and for this purpose the common anchoring element can be connected to two or more shuttering elements which are adjacent to one another ,
  • the anchoring element can advantageously be designed such that it functions as a common anchoring element for two or more shuttering elements or devices adjacent to one another and for this purpose the common anchoring element can be connected to two or more shuttering elements which are adjacent to one another ,
  • this grid can be placed on the component reinforcement of the building component and only has to take into account the position of the tensile reinforcement elements.
  • the formwork device according to the invention can be used in a particularly advantageous manner for being used in an otherwise commercially available or known component for thermal insulation.
  • the formwork device is assigned to the traction elements of this component for thermal insulation and provided on the side of the building component, which in turn several tensile elements can be assigned a common formwork device, so for example, each traction element a formwork element and a plurality of formwork elements a common anchoring element.
  • this time-shifted incorporation constitutes a time difference of many days or weeks.
  • the scaffold close to the building wall during the construction of the building, which may be important and advantageous especially in confined construction sites. Then, when the building is erected, the connecting of the cantilevered components can be done later, to which then either a new scaffold with a greater distance if necessary, or maybe even can be worked with mobile platforms and cranes, in which case the corresponding to be connected reinforcing elements positioned in the recess and the filler is filled into the recess and thereby the desired positive connection between the reinforcing element, filler and building component is produced.
  • the components for thermal insulation with the reinforcing elements and possibly together with the attached projecting components can be easily mounted by being inserted from above with their traction reinforcing elements in the recesses. Because of the oversize of the recesses relative to the reinforcing elements, this does not require particularly high accuracy during assembly - and also the subsequent alignment of the component with respect to the building component is - as long as the filler is not entered into the recess - easily and simply possible because of the above excess.
  • the method according to the invention is also distinguished by the described advantages if a decoupling of the assembly sequence is provided correspondingly between method step b) and method step c).
  • the recess can be created in the building component at any first time and the connection of the reinforcing element to this recess can be made to an arbitrary second time independent of this.
  • one can even take advantage of this by providing a building with a large number of recesses and using these recesses only when needed, while otherwise they could be temporarily or permanently closed without having the corresponding reinforcing element placed therein must become.
  • the formwork element can be removed from the recess after the building component has been cast.
  • This process step e) can be carried out expediently between the process steps b) and c).
  • shuttering device 1 in the FIG. 1 illustrated shuttering device 1 according to the invention consists of several parallel to each other substantially in the horizontal direction arranged shuttering elements 2, which are made of cup-shaped plastic, as well as arranged perpendicular thereto and the shuttering elements respectively in the region of its underside acting rod-shaped anchoring elements 3.
  • the shuttering device 1 is in FIG. 1 in a position attached to a formwork panel 4 for a building component (not shown) as it corresponds to the place of installation on the construction site, but this formwork panel 4 is not part of the formwork apparatus of the present invention.
  • FIG. 2 and in particular in particular FIG. 3 show how the anchoring element 3, which consists of a cylindrical reinforcing rod made of structural steel, cooperating with the formwork elements 2:
  • the two mutually parallel anchoring elements 3 penetrate the formwork element in its lower region and thus extend - as from FIG. 4 can be seen - partly through the inside of the formwork element and thus have an inner region 3a and outer regions 3b (see FIG. 4 ).
  • the formwork element now serves to provide a recess (indicated by reference numeral 5, which corresponds to the inside of the formwork element 2) in the building component bounded by the formwork panel 4.
  • a recess indicated by reference numeral 5, which corresponds to the inside of the formwork element 2
  • the concrete of the building component is adjacent to the formwork elements 2, but then the desired recesses 5 are left in this area.

  • the filler flows into the lower regions of the anchoring element 3 and thus encloses them after curing form-fitting, so that a lifting of the filler 15 analogous to the removal of the formwork element 2 is then no longer possible, since the filler this positive connection is not destructive can pick up.
  • the shuttering element has a total corrugated in the horizontal direction outer shape, which is mainly intended to be in traction force, ie horizontally in the direction of the panel 4 also enter into a positive connection with the building component.
  • the waves of the formwork element thus have a total of a rib shape with mutually parallel ribs.
  • an enlarged rib 2a is provided, which serves to accommodate a corresponding bend of the rebar to be inserted into the recess 5.
  • Such a bent reinforcing rod has the advantage of getting along with an overall shorter length of engagement of the reinforcing bar in the building component. Moreover, this turn provides for a further positive connection between the reinforcing element, filler and building component.
  • the formwork element 2 has a total of vertical section a nearly V-shaped outer shape through which the ribs are also almost V-shaped, so slightly different from the vertical.
  • This conically inclined shape has the essential purpose to facilitate the removal of the formwork element 2 from the building component and at the same time to allow the gapless filling of the filler into the recess 5.
  • FIGS. 9 to 13 An alternative embodiment of a shuttering device 11 is in the FIGS. 9 to 13 represented, in which the formwork elements are designed substantially identical and are therefore provided with the same reference numerals.
  • the main difference is the shape of the anchoring elements 13, namely not - as in FIG. 1 consist of a cylindrical continuous reinforcing bar, but are also designed to be substantially wavy and in the respective outer region 13b are angled slightly upwards, where they serve to be placed on a connection reinforcement 14 for the building component or cooperate with this.
  • the shuttering device 11 according to the invention positionally accurate in (not yet filled with concrete) building component, then then the Reinforcement elements with the given reinforcing rod in the created recesses 5 can use.

  • FIG. 6 shows in vertical section a building component 6, in which on its upper side 6a and end face 6b adjacent the recess 5 is provided, which - as is easily apparent - corresponds to the shape of the formwork element 2, but in the illustrated embodiment, the formwork element is already removed from the building component and only its undulating shape has transferred to this surrounding building component.
  • the anchoring elements 3 are left in the building component and extend with their inner region 3 a, which mainly consists of FIG. 5 can be seen through the recess 5. Due to the cylindrical shape in this case undercut recess areas are provided which provide the desired positive connection between the filled into the recess filler 15 and the building component 6.
