Definitions

the invention relates to a formwork element explained in the preamble of claim 1 Art.
Such a formwork element is for example from the EP-A-532 908 known.
the known formwork element two in the same plane, but at a distance adjacent formwork walls are connected to each other via a basket-like bow construction, which projects on both sides of the formwork walls.
this basket-like bow construction grout locks, for example in the form of an elastic joint tape, inserted and possibly positively fixed by bending the legs of the bracket construction.
Such a holder is particularly suitable for elastic joint tapes, which are provided in their longitudinal center line with projecting ribs with which their position in the bracket construction can be fixed laterally.
the invention has for its object to provide a formwork element with a simple and secure support for a joint barrier, which is particularly suitable for the use of joint plates.
joint barriers of various kinds can be easily connected to the formwork walls, without welding would be necessary. Therefore, the invention is also particularly suitable for mounting joint plates, which are either coated and / or made of a non-weldable material. But also joint tapes of elastomeric materials can be connected in the manner according to the invention with the formwork walls in a predetermined orientation.
clamping means are used, with which a joint barrier is frictionally clamped fixable.
the non-positive, clamping fixation by a clamping device which may be part of the connection means, for example, with which the formwork walls are connected to each other via the gap therebetween.
the non-positive, clamping fixation of the joint barrier can also be done by the formwork material itself, which preferably formed elastically in edge regions, deflected when inserting the joint barrier and retains holding by spring properties of the joint barrier.
the clamping means of the connecting device can be designed in different ways.
the connecting device includes a bracket with resilient legs, wherein the legs form the clamping means for the joint barrier.
a resilient element is preferably used, which is arranged on the connecting device or is part of the connecting device.
a depth stop is preferably provided which limits the depth of insertion of the joint barrier in the gap.
the connecting device consists of a plurality of spaced apart with two formwork walls connected brackets, which are connected to one another via a brace.
This bracing may preferably be designed as a depth stop.
the distance between two legs of the bracket can be determined by the brace, which corresponds to the desired clamping distance.
the brackets may be formed as a single bracket, but may also be arranged on a stiffening carrier connected to the formwork wall.
Fig. 1 shows a first embodiment of a formwork element 1 according to the invention, which is preferably designed as a joint formwork element and preferably as a lost formwork element, ie, remains in the concrete.
the formwork element 1 contains two formwork walls 2, which are strip-shaped for joint formwork, but this need not be.
the Formungswandungen 2 are arranged on both sides of a gap 3, and are in the illustrated embodiment in the same plane opposite.
the gap 3 extends over the entire length of the formwork walls 2 and is fixed in a predetermined width b by a connecting device 4, which is fixedly connected to two shuttering walls 2.
the formwork walls 2 may consist of any suitable formwork material, but are preferably made of metal, so that a likewise made of metal connecting device 4 can be welded to the formwork walls 2 in a simple manner.
the material of the formwork walls 2 is limited concrete permeable to ensure a rough connection surface.
a preferred material for the formwork walls 2 is expanded metal in any known design.
the connecting device 4 includes in the illustrated embodiment, a plurality of brackets 5, which are arranged at a distance from each other along the gap 3.
each bracket 5 preferably has a substantially omega-shaped shape, wherein at least two first legs 5a are provided, which abut the gap 3, extend substantially perpendicular to the plane of the gap 3 and extend over a predetermined range K parallel to each other. Both legs 5a have a distance from one another, which corresponds essentially to the width b of the gap 3.
the bracket 5 further comprises fastening means in the form of second legs 5b, which extend substantially parallel to the shuttering wall 2 and fixed thereto, preferably welded, are.
the second leg 5b extend over the entire width of each formwork wall second
first and second legs 5a, 5b The transition between the first and second legs 5a, 5b is provided with a fillet R, through which the legs 5a, 5b lift slightly from the respective adjacent formwork wall 2.
the legs 5a, 5b each side of the bracket 5 are connected via a connector, for. B. a connecting sheet 5c connected to each other.
the bracket 5 is preferably bent with the legs 5a, 5b and the connecting sheet 5c of a metal rod.
the plurality of brackets 5 of the formwork element 1 is connected to one another via a substantially parallel to the gap 3 extending connecting strut 6 and held at a predetermined distance along the gap 3, wherein the connecting strut 6 formed as a metal rod and preferably at the transition between the first legs 5a and Compound 5c is welded to the straps 5.
the strut 6 is preferably arranged so that it holds the two legs 5a at a distance from each other, which is preferably approximately equal to the width b of the gap 3 and smaller than a predetermined thickness d of a commercial joint seal 7.
the strut 6 is perpendicular to the plane of the gap 3 and at a distance to this, which is about half the width of the joint barrier 7 (FIG. Fig. 2 ), which is shown in the illustrated embodiment as a joint plate with exaggerated drawn thickness d to make the presentation clearer.
the joint seal 7 or the joint tape is commercially available and has a commercial thickness d.
the thickness d of the joint barrier 7 is greater than the width b of the gap 3 and thus larger than the distance between the two legs 5a of each bracket 5.
the width b and the distance between the legs 5a thus forms a clamping distance A K , in the the joint barrier 7 is pressed under elastically resilient displacement of the adjacent elements.
the clamping distance A K can be chosen so that all or at least a plurality of commercially available thicknesses d are covered.
the formwork element can be completed with the formwork walls and the connecting device 4 factory and delivered to the site.
the joint seal 7 so for example, a commercial joint plate, pressed into the gap 3, whereby initially the formwork walls 2 deformed by the radius R and then the legs 5a are pressed resiliently apart so that preferably over the entire extension K of the legs 5a, a clamping force can be applied to the joint barrier 7.
the brace 6 acts as a depth stop, which limits the insertion of the joint barrier 7.
Fig. 3 shows a further embodiment of a formwork element 10 according to the invention, which corresponds to the formwork element 1 except for the modifications described below, so that identical or comparable components are marked with the same reference numerals and are not explained again.
the formwork element 10 differs from the formwork element 1 only by double-sided, additional stiffening support 11, which additionally connect the connecting device 4 with two shuttering walls 2.
the stiffening beams 11 are in the form of conventional, flat lattice girders and contain two mutually parallel rods 12a and 12b, which are connected by zig-zag or arcuate transverse rods 13 with each other.
the first longitudinal bar 12a is fastened, for example, to the connectors 5c of the brackets 5 and the second longitudinal bar 12b is fastened to the associated formwork wall 2, preferably welded, so that a roof-shaped reinforcement for the connecting device 4 results.
the non-positive clamping can only be done either by the edge regions of the formwork walls or by the connecting device, in particular their bracket. Under certain circumstances, it may be sufficient to form only one of the edge regions elastically bendable. Also, the clamping distances in the region of the connecting device and in the region of the gap need not necessarily be the same width. It is also possible to provide a clamping outside the connecting device by an external and / or connected to the connecting device clamping device. The legs of the bracket must not necessarily have linear contact over their entire length with the joint barrier, but they can also run obliquely to the joint barrier and only over a small portion of their length, for example, by a deflection, are in clamping contact with the joint barrier.
the clamping means may further comprise a separate spring element which is not part of the connecting device.
