Definitions

  • the invention relates to a connecting device for connecting or fixing plates and / or reinforcements of a composite formwork at a distance from one another.
  • the panels that make up the formwork are assembled into elements.
  • Wood-based panels are preferably used as panels.
  • the elements are precisely assembled on site and poured with concrete.
  • the panels remain on the structure as so-called lost formwork.
  • Such composite formwork can be used to manufacture vertical and sloping walls, ceilings (also sloping Ceilings) as well as columns and other components, such as stairs.
  • Composite formwork enables the erection of structures in a very short time.
  • connection devices In order to hold or fix the slabs and / or any existing reinforcement of a composite formwork, suitable connection devices must be available. These connecting devices are intended, for example, to absorb the forces occurring when the composite formwork is being transported to the construction site or in particular when the concrete is being introduced into the composite formwork.
  • a connecting device of the type mentioned is known from EP-OS 179 046.
  • the two-part connecting device has a first element, the plate-shaped foot part of which can be fixed on a first plate of the composite formwork.
  • a web projects vertically from this foot part, the free end of which is formed with a head.
  • a second element of the connecting device has a funnel-shaped head which can receive the head of the first element. To make the connection, the two elements are locked together.
  • the Swiss patent CH-PS 669 235 also shows a series of connecting devices for connecting two formwork halves that are located at a mutual distance from one another. Some design variants are described in which wall sleeves attached to the formwork halves and corresponding coupling bolts can be connected to one another.
  • connection device is known from EP-PS 258 205.
  • the two-part connecting device has a first element which is U-shaped in cross section is formed and has two webs with undercuts.
  • the second element is provided with webs, on which recesses are arranged, into which the undercuts of the first element can snap.
  • the two elements are arranged in a cross shape to one another in the connected state.
  • the two elements must be precisely aligned with one another in order to ensure that they snap into place when the composite formwork is being installed.
  • the invention has for its object to provide a connecting device of the type mentioned that allows a simple connection of the plates and / or reinforcements and can absorb the forces occurring during transport and use of the composite formwork.
  • one of the connecting means can be designed as a plug-in part and the other connecting means as a receptacle for the plug-in part.
  • the connecting means have a corresponding shape, so that a particularly simple connection is possible.
  • the connecting device is preferably designed such that the second connecting means can be fixed on a plate. This determination can be made in any way, for example by gluing or gluing. However, a screw connection is particularly preferred when using wood-based panels.
  • the definition can be made at the edge area of the second connecting means. This border area is easily accessible for definition.
  • the edge area is expediently ring-shaped if a second connecting means with a rotationally symmetrical structure is used. A greater material thickness can be provided at the locations of the edge area where, for example, a screwing to a plate is to take place. These "increases" ensure that the connecting means has improved stability at the screwing points.
  • the first connecting means is designed as a plug-in part and the second connecting means as a receptacle for the plug-in part.
  • the insert part has at least one undercut and the receptacle has at least one holding means which interacts with the undercut.
  • the second connecting means preferably has a rotationally symmetrical shape. As a result, no alignment is normally required when assembling this connecting means, so that assembly is simplified.
  • the second connecting means has a substantially conical shape. It is expediently designed as a truncated cone, which can additionally have an annular edge region for fastening the second connecting means to a plate. Due to the essentially conical shape, the connecting means designed in this way can be stacked on top of one another in a simple manner, which represents a significant advantage.
  • the holding means is preferably formed on the inner edge of an opening in the second connecting means.
  • This opening is preferably located in the middle of the second connecting means and can have any shape. However, a circular opening is preferred because it can be produced in a simple manner.
  • the holding means can be formed by the possibly reinforced inner edge of the opening itself.
  • the inner edge can have the shape of an undercut running around the opening, which projects inwards from the upper side of the second connecting means.
  • the undercut can form an angle of approximately 30 ° with the horizontal.
  • notches or grooves can be provided on the upper side of the second connecting means, which enable the reinforcement bars of a reinforcement, for example a reinforcement mat or a lattice girder, to be supported. Notches or grooves which are perpendicular to one another are expediently provided since the reinforcements usually have reinforcing bars which are perpendicular to one another.
  • the number, length and spacing of the notches or grooves can be chosen freely and are primarily determined by the dimensions of the second connecting means and by the reinforcement used.
  • Recesses for example in the form of a groove running around the opening, can additionally be provided on the upper side of the second connecting means. Such cutouts serve, for example, to save material. Openings can be provided on the side surfaces of the second connecting means, through which the filled concrete can more easily get into the interior of the connecting means during use. This increases the stability of the overall construction.
  • the first connecting means is constructed from a base part and a connecting part which projects substantially vertically from the base part.
  • the undercut present on the first connecting means is provided in particular on the connecting part.
  • the connecting part is in particular cylindrical, expediently constructed as a hollow cylinder.
  • the connecting part in the middle have a smaller diameter than at the upper and lower end, whereby the diameter can decrease evenly from the ends towards the middle.
  • the first connecting means comprising the base part and the connecting part can be formed in one piece. It is also possible for the base part and the connecting part to be irreversibly connected to one another.
  • the base part can have a simple shape, such as that of a plate. As a result, this part is easy to manufacture and unnecessary material expenditure is avoided.
  • the concrete used to pour the composite formwork can flow around the first connecting means and the connecting part as well as any reinforcement that may be present. It is preferred if the first connecting means consisting of the base part and the connecting part, but in particular the connecting part, are constructed rotationally symmetrically. In addition to the cylinder shape already mentioned, square or star-shaped cross sections of the connecting part are also possible, for example.
  • the undercut on the first connecting means is preferably provided on the connecting part.
  • the undercut is formed on a projecting edge or thickening of the connecting part, which points in the direction of the base part and in particular projects like a saw tooth in the direction of the base part.
  • an undercut with a sawtooth shape can preferably form an angle of approximately 30 ° with the horizontal.
  • the edge or thickening enables a positive and / or form-fitting interaction of the two connecting means.
  • sawtooth-like undercuts there is a barb-like connection of the two connecting means.
  • At least one is on the connecting part from the upper end of the connecting part in the direction of the base part extending slot provided.
  • the slots at the upper end of the connecting part are preferably open.
  • the slots increase the elasticity of the upper end of the connecting part, so that a better connection (snapping) with the second connecting means is achieved due to the at least slightly resilient effect.
  • the slots can be made over the entire length of the connecting part up to the base part.
  • the slots on the inside of the connecting part can have a smaller diameter than on the outside. The snap-in or, in some circumstances, desired demolding of the connecting device is facilitated by the tongue-shaped spring elements formed in this way.
  • the slots also have the function that the concrete can flow more easily around or into the connecting means and around any reinforcements when filling the composite formwork. This further improves stability.
  • slots other than those mentioned above can also be provided on the connecting part.
  • the thickenings provided at the upper end of the connecting part, which form the undercut have a conical shape. This facilitates the insertion of the connecting part into the second connecting means serving as a receptacle. At the same time, this makes it possible to stack the first connecting means one above the other.
  • the stackability can be further improved by providing a possibly annular recess on the underside of the first connecting means, in particular the base part. This recess can then be placed on the top of another connecting means or base part.
  • the connecting part has lateral webs in the longitudinal direction. These webs can be designed at the upper and / or lower end so that they are supported in the locked state on the base part of the first connecting means or on the second connecting means. This further increases the stability of the overall device, for example against tilting.
  • the construction of the web ends can at the same time be such that reinforcements that rest on the connecting means can be fixed or attached to them.
  • the webs can be tapered towards the middle of the connecting part. If necessary, there is no web in the middle, although the web width can decrease evenly from the ends. This simplifies the machinability of the connecting part in a machine during manufacture and saves material.
  • Two webs can be provided on opposite sides of the connecting part. There are preferably four webs, which are each offset by 90 ° on the outer circumference of the connecting part. The webs can be present in particular in the extension of the slots provided at the upper and / or lower end of the connecting part.
  • Reinforcements in particular in the longitudinal direction, can be provided on the inside of a hollow (tubular) connecting part for further stabilization.
  • Such reinforcements are particularly advantageous in the area of the spring elements formed at the upper and / or lower end of the connecting part.
  • notches or grooves can be provided on the first connecting means for supporting reinforcing bars of a reinforcement. These notches or grooves are preferably located on the top of the base part and are parallel and / or arranged perpendicular to each other. In this way, as already described in the description of the second connecting means, reinforcements and / or plates can be connected or fixed against each other.
  • the first connecting part can also be designed such that it can be fixed on a plate.
  • second connecting means can also be designed such that it can be fixed on a plate.
  • the connecting part in the first connecting means the connecting part is designed as a part which can be plugged together with the base part.
  • the connecting part can be connected not only to the second connecting means, but also to the base part or, under certain circumstances, be separated from it again.
  • the base part can be more easily attached to a plate. If, for example, two plates are to be connected to one another, the base part is first fastened on one plate and the second connecting means on the other plate. Then the two plates are connected to each other with the help of the connecting part.
  • the length of the connecting part can be selected so that it is supported on the panels of the composite formwork on preferably both sides in the engaged state. This increases the stability of the construction.
  • the second connecting means is attached to a plate that is provided as the underside of the ceiling. Then a reinforcement is placed and this is fixed with the help of the first connecting means, possibly using a connecting part. In this case, the first connecting means is not fixed on a plate.
  • the base part has essentially the same shape as the second connecting means.
  • the connection device is simplified. Two identical parts, namely two second connecting means and one connecting part, are required for connecting two plates.
  • the connecting part can already be firmly connected to one of the two second connecting means (base part) or can be subsequently attached to it.
  • the same construction is possible when constructing a ceiling.
  • a second connection means and a differently designed first connection means can also be provided.
  • the connecting part can be of essentially the same design on its two opposite sides. This applies in particular to the connecting part that can be separated from the base part.
  • the connecting part has the same structure on both sides, i.e. it has essentially the same thickenings, undercuts, slits, etc. as have already been described.
  • the slots and thickenings at the two ends of the connecting part can be offset relative to one another. In this way, better stability (statics) of the composite formwork produced with the aid of the connecting devices is achieved.
  • the flow of the concrete into or around the connecting device can be improved.
  • the connecting device according to the invention can be made from a wide variety of materials which ensure the required strength. It is preferred if the Connection device made of plastic. PVC can be used as a plastic, for example, but the use of polypropylene, in particular so-called recycled polypropylene, is preferred. In these cases, the connecting device consists of conventional plastic cast or plastic injection molded parts.
  • the connecting devices according to the invention described can absorb large forces without difficulty.
  • composite formwork can be created for all the components mentioned at the outset, which have improved stability under the possible loads that may occur.
  • larger spans can be bridged. Fixing filigree carriers, especially in ceiling construction, is also easily possible.
  • the invention also relates to a lost composite formwork with at least one plate and / or at least one reinforcement, in particular at least one reinforcement mat or at least one lattice girder, the composite formwork being connected to one another or via a plurality of connecting devices consisting of a first and a second connecting means are fixed among themselves.
