Definitions

  • the invention relates to a connector for holding together two, the finished wall or ceiling surface of a lost formwork, which are fixed at a distance from each other for the production of reinforced concrete walls, sloping ceilings or the like fixable sheet metal parts that can be connected to one of the base plates, for example by screws.
  • Such a two-part connector has become known from EP-B-0 258 205, in which two differently shaped parts of the connector are non-positively connected to each of the base plates and at least one of the parts has undercuts into which the other part snaps when the formwork panels are assembled .
  • One U-shaped part and the other X-shaped part are each connected to the corresponding base plates of the formwork by several screws.
  • the construction permits certain assembly inaccuracies and still enables full longitudinal force transmission to absorb the resulting formwork pressure when filling the formwork. Since the formwork elements preassembled in this way must have a certain intrinsic stability for transport, the latched connecting piece is required to have a corresponding rigidity and transverse force transmission.
  • the present invention has for its object to provide a connector of the type mentioned, which has a significant simplification in terms of shape compared to the previously known connector and which meets the same requirements in terms of stability and security, but is much cheaper to manufacture.
  • Snap-in and mutually fixable sheet metal parts which can be connected to one of the base plates, for example by screws, are proposed, which is characterized in that the two parts are identical, each part being made from a base plate with a cross-shaped punched-out cross-section in its crossbeam area, there is a resilient tongue which engages in a form-fitting manner in the released, likewise cruciform recess of the second part when the parts engage against one another, the part for the screw connection with the base plate having at least one perforated, bent tab.
  • the connecting piece according to the invention With the connecting piece according to the invention, the main advantage is achieved that the fixing of the two base plates of the formwork can be simplified and reduced in cost as far as the piece itself consists of two identical parts, for whose manufacture only a punching and shaping tool is required.
  • the connection of the two base plates of the formwork is extremely good in terms of its stability.
  • cutouts and openings can be provided for an inclined wall or ceiling, into which lines and additional reinforcements can be inserted, this process being able to take place independently of the actual setting process of the formwork on the construction site.
  • the connector according to the invention is that the foot of the motherboard has a division into four perforated pull tabs, two of which are bent out obliquely to increase the distance between the holes and are all bent at the ends so that the holes are flat on the Base plate come to rest. An extraordinarily good and secure attachment to the base plate is thus achieved.
  • the head part of the base plate is bent in the opposite direction to the head end of the tongue, in such a way that two catch bevels are formed, on which the parts can slide along when pushed together.
  • the connecting piece according to the invention can be modified in such a way that the cutout in the sheet metal in the area of the crossbar resulting from the partial punching out of the cruciform tongue is enlarged in the transverse direction by the assembly-related Take up positional deviation of two opposing parts in this direction, that is, a transverse displacement is possible, and yet a complete engagement and straight guidance is guaranteed.
  • additional catch bevels can be provided in order to ensure that the parts slide out against one another in the end position, with the connecting piece also being given additional tension shortly before it engages.
  • each connecting piece can also be designed in the form of a wide, bent tab, in which stiffening beads and relief-producing bores are provided, which produce a heavy-duty adhesive connection between the base plate of the formwork and the connecting part.
  • the connecting piece according to the invention consists of two identical sheet metal parts, one of which is shown in FIGS. 1 to 3.
  • Each part consists of a base plate 1, from which a cross-shaped tongue 2 is punched out, which is bent out relative to the base plate 1 and is resilient.
  • the head part 3 of the sheet metal plate 1 and the head end 4 of the tongue 2 are bent in the opposite direction in such a way that two catch bevels are formed, on which the parts can slide along when pushed together.
  • four pull tabs 5 with holes are arranged for attachment to the base plates of the formwork, the middle two of which are bent out obliquely to increase the hole spacing. All four pull tabs are bent at the end so that the holes 6 come to lie flat on the base plate.
  • the cutout formed in the sheet metal by punching out the cross-shaped tongue 2 has an enlargement on both sides in the area of the crossbar of the tongue 2 7 to take up the mounting-related positional deviation of two opposite parts in this direction. Due to the shape shown, the bent-out resilient tongue has two play shoulders 9 on the upper side and two load shoulders 10 on the underside, which come into engagement with the load shoulders 8 in the board.
  • FIG. 7 shows a perspective view of the lower foot part of the circuit board 1 in another embodiment. Accordingly, a wide tab 12 is provided at right angles to the circuit board 1, which has stiffening beads 13 or holes 14 producing relief. This embodiment of the foot part is used for the adhesive fastening method to be described later.
  • the invention also relates to a method for fastening the identical parts to the inner walls of the base plates 15, 16 of the formwork.
  • FIG. 7 from which it can be seen that the foot part with the tab 12 is relatively wide. Any indentations 17 can be provided on the underside of the tab 12.
  • An adhesive can be applied to this underside, which then partially penetrates into the indentations 17.
  • the flap can be firmly glued to the inner wall of the plates 15, 16 and the part can additionally be fixed to the inner wall by means of a screw or nail clip passing through the bore 14.
  • This method results in an extraordinarily good and inexpensive fastening of the two identical parts of the connecting piece on both inner walls of the base plates 15, 16.
  • the arrangement shown with the corner stiffening beads makes it possible to connect the connecting part with a single screw in the centrally arranged bore 14 to fix or with three to four nail clamps to achieve the remaining holding force via the flat adhesive below the tab 12 cohesively.
  • FIG. 9 shows a further embodiment of the connecting piece according to the invention.
  • the tongue 2 punched out of the motherboard 1 has a widened head end 18. Furthermore, two bent tabs 19, 20 are punched out on both sides of the tongue 2. Finally, a widened opening 21 is provided in the head part 3, such that two inwardly jumping parts 22, 23 are formed in the motherboard.
  • the foot part of the circuit board 1 is also somewhat different.
  • two tabs 24, 25 are bent at right angles and in the opposite direction. Opposite these tabs are two more tabs 26, 27 provided, which lie with the tabs 24, 25 in one plane. All tabs have holes 28 for fastening screws.
  • two spike-like projections 29, 30 are bent out of the tabs 24, 25 and engage in corresponding bores in the formwork boards.
  • FIG. 10 shows a further possible embodiment of the foot part of the circuit board 1.
  • two tabs 31, 32 are bent apart at a certain angle, the ends 33, 34 of which are bent toward one another and form a plane with one another which corresponds to the plane of the formwork.
  • further thorn-like projections 35, 36 are bent out of the tabs 31, 32 and can have a bead for stiffening. These projections 35, 36 also engage in corresponding recesses in the formwork.
