Definitions

  • the invention relates to a device for displaceable arrangement in groups of structural elements, in particular shear reinforcement elements, as they do preferably used against punching flat ceilings.
  • components to be arranged in groups so that they are on the one hand in a statically permissible manner can be moved to avoid problems during installation, on the other hand, however, not without force from the entire reinforcement unit can be removed.
  • This object is achieved in that initially a support system is specified in which the reinforcement elements only in a statically permissible Partial area can be moved.
  • the movability itself is guaranteed through connecting elements that are firmly connected to the reinforcement elements are and exclude their non-violent release from the support system. Simultaneous allows any shape within the defined limits Moving the reinforcement elements. If necessary, the connecting elements be designed so that the reinforcement elements even at any desired Position can be fixed immovably.
  • FIG. 1 shows a shear reinforcement unit in the double-headed bolt as an example 1 with the help of connecting elements 2 non-detachable but movable in some areas, are connected to a support element 3.
  • the support element consists of this example from two parallel longitudinal bars 4, whose Cross section can be rectangular, round or arbitrarily shaped.
  • the longitudinal bars 4 are connected with the help of cross bars 5 to form a ladder-like unit.
  • the position of the crossbars is chosen so that they are the statically required ones Ensure limitation for the movement of the individual reinforcement elements.
  • FIG. 2 shows the side view of the shear reinforcement unit according to FIG. 1.
  • FIG. 3 shows how the exemplary embodiment shown in FIGS. 1 and 2 can be assembled in a simple manner and still have the desired ones Requirements fulfilled.
  • the connecting element 7 is first attached. This exists in the present Example from a sufficiently thick holding plate, the middle part 8 cut and bent down. This part of the connector forms the foot, which is firmly connected to the reinforcement element.
  • the plate 7 In the In the middle, the plate 7 has two depressions 9, which are formed by a central upstand are stiffened. The adjacent, side parts 10 are before attachment bent upwards at the shear reinforcement. This will make the effective Width of the holding plate temporarily reduced so much that it easily between the two longitudinal rods of the ladder-like support device are inserted can.
  • the position of the cross bars 5 is determined in that they are the statically permissible Limit the displacement range of the reinforcement elements reliably. Between Cross bars may therefore remain in the reinforcement elements at any point. Should there still be a desire to place them at a certain point fix, this can be easily achieved by the respective reinforcement element is rotated by a maximum of 90 degrees around its longitudinal axis. As can be seen from FIG. 7, then the depressions in the middle sheet metal area run through the central one Upstand are braced so far on the longitudinal bars of the support device, until they jam and no longer move without external influence. Figure 8 shows this position of the holding plate in plan view. The movability can of course, can be easily restored by adding another piece of reinforcement Is rotated 90 degrees.
  • FIG. 9 shows a further embodiment of the device according to the invention.
  • the support element 12 consists of a thick sheet of metal into which Elongated holes 13 and further circular openings 14 were punched.
  • the location and size of the elongated holes are determined by the conditions for installation of the reinforcement elements. Its center corresponds to the target position of the reinforcement. Their length results from the permissible displacement dimension of the reinforcement elements. Finally, their width must ensure sufficient space for the connecting element.
  • the openings 14 offer 13 options in addition to the elongated holes for fastening the reinforcement unit with the bending reinforcement. You worry in addition to ensuring that no harmful damage occurs under the sheet metal support when concreting Form air bubbles. Finally, they can be used to make items inserted through the openings to secure the position and thus extremely simple can be assembled.
  • Double-headed bolts 1 are also shown by way of example in FIG. 9 as shear reinforcement. You are now with a connecting element 15 adapted to the situation fitted. In Figure 10 is the situation of the assembly of the reinforcement elements 1 shown with the support member 12.
  • a cost-effective solution is instead of a solid construction a sufficiently thick sheet is provided for the connecting element 15. Its sectional shape is shown in FIG. 11. It was chosen so that the Punching out of a longer sheet metal strip creates almost no waste.
  • the in middle area selected form again offers the possibility of the reinforcement elements to lock if desired.
  • the opening in the middle 16 of the holding plate offers the easy option of holding the holding plate with the reinforcement element to connect with a single weld spot.
  • the dashed lines 17 indicate the course of the required sheet metal bends on.
  • the edges 17 a are to be produced.
  • the holding plate gets thereby the side view of the U-shape 15 a shown in Figure 10.
  • the width of the connecting element in this state determines the required Width of the elongated holes 13 of the carrier plate 12.
  • the connecting element is inserted into the elongated hole 13 until the upper edge of the reinforcing element abuts the carrier plate.
  • the holding plate is along the Bending lines 17 b bent outwards for locking with mechanical help, until it assumes the shape 15 b shown in FIG. 12, in which the two Extend wings slightly offset from each other.
  • the reinforcement element can be attached if desired can be locked in place with minimal effort. It just has to go again the reinforcement element can be rotated around its axis - in the illustration 9 clockwise. Jam after a rotation angle of less than 45 degrees the rounded parts 18 of the holding plate with the walls of the carrier plate. This position is shown in plan view in FIG. Like in You can also use the previous example here by turning back to the initial state be made movable.
  • a variant of the locking options shown here is to bend the retaining plates to the extent that they move create a frictional resistance. As a result, they are constantly locked. If they are to be moved in this embodiment variant, this is done by light hammer blows against the head end of the reinforcement elements.
  • FIGS. 14 to 18 show the elements of a further variant of the invention Device that due to the simplicity of both the wearer and the Connection elements represents a particularly economical solution. Deviating The reinforcement elements of this solution can be used with this solution cannot be fixed at a certain point. In general, however, this is also not necessary, since the reinforcement elements are attached to any one anyway Location within the opening 13 may be.
  • FIG. 14 first shows the particularly simple sectional shape of a connecting element 19 from a sheet with the centrally arranged opening 20 and the course the required sheet metal bends 21 a and b.
  • the connecting elements can also be in advance in the final Form are bent and only then with the reinforcement elements and be joined to the carrier.
  • FIG. 15 shows the side view of the connecting element 19 which has been completely folded beforehand.
  • the reinforcement elements 1 are in this manufacturing variant with the support device 22 compiled and on the carrying device are each over the Reinforcement elements 1 connecting elements 19 arranged. With a spot weld in the opening 20, the reinforcement elements with the help of the connecting elements connected to the carrying device - non-violently non-releasable.
  • the figure 17 shows a partial top view of the assembled elements.
  • the overall plan view shown in FIG. 18 of the device according to the invention shows the simplicity and optimal functionality of this variant.
  • Deviating The sheet metal support 22 was designed in this way from the example shown in FIG slightly varies that when cutting from the coil not a right angle, but a arrow-shaped section (23 a and 23 b) is provided. This is the simplest Achieved that a clear installation direction is specified for the support device can be.
  • the small openings 24 offer further possibilities Fixing device with reinforcement.
