Definitions

  • the invention relates to a wedge element, a spacer with at least one such wedge element, a positioning device with such a spacer and a method for positioning wall formwork according to the respective independent claim.
  • the wall formwork is arranged in such a way that concrete can be poured in between.
  • the wall formwork is positioned in advance of the casting process in such a way that the thickness of the wall to be created corresponds as precisely as possible to the specifications.
  • the Swiss patents CH687471 and CH651882 of the company Mägert Bautechnik AG and the Swiss patent application 0781/15 from the company Mägert & Co. Innovation disclose methods and devices for positioning wall formwork.
  • a wedge element according to the preamble of the claim is from CH 713 432 A2 known.
  • the devices include, among other things, plastic parts that are used as stop elements for the wall formwork. These are attached to the ends of a spacer rod (round iron). Their outer surface facing the wall formwork to be attached serves as a reference for the intended position of the wall formwork.
  • the devices for positioning wall formwork are used in the manner described below.
  • the floor on which the walls are to be erected consists of reinforced concrete, the so-called reinforcing iron or reinforcing rods of which protrude upwards essentially vertically from the floor during the construction phase.
  • the positioning devices described above are attached to these reinforcing bars.
  • the spacer bar with attached stop elements hereinafter referred to as spacers, is positioned on the reinforcement bar by means of a profile and then attached so that it cannot slip and thereby falsify the intended position of the wall to be built.
  • a wedge is driven between the reinforcement rod and the spacer rod.
  • a disadvantage of positioning devices in which a wedge is driven between the reinforcement rod and spacer rod is that the wedge is supplied loose with the spacer rod and can thus be lost, or the wedge is connected to the spacer rod but can no longer be inserted by hand between the reinforcement rod and spacer rod can.
  • the object of the invention is therefore to find a solution to the disadvantages mentioned above.
  • the object is achieved with a wedge element, a spacer with such a wedge element, a positioning device with such a spacer and a method for positioning and fixing the positioning device.
  • a first aspect of the invention relates to a wedge element with a displaceable fastening device for fastening the wedge element to a positioning device for positioning wall formwork when creating a concrete part.
  • the wedge element is designed to fix the positioning device on a reinforcing rod of the concrete part and comprises a wedge-shaped main body with a first and a second active surface causing a wedge effect.
  • the wedge element can be fastened to a spacer rod of the positioning device by means of the fastening device, so that the first active surface faces the spacer rod.
  • the fastening device is arranged on the first active surface of the main body and connected to it in such a way that the main body is displaceable in relation to the fastening device essentially in the direction of the wedge effect of the wedge element and in the opposite direction.
  • a second aspect of the invention is concerned with a spacer comprising a spacer rod which has a stop element at least at one of its ends, preferably a stop element at both ends.
  • the spacer further comprises at least one wedge element according to the first aspect of the invention.
  • the wedge element is fastened to the spacer rod by means of its fastening device in such a way that it is freely displaceable along the spacer rod.
  • a positioning device for positioning wall formwork when creating a reinforced concrete part.
  • the positioning device comprises a spacer according to the second aspect of the invention and a profile with a guide section for receiving a reinforcing rod of the reinforced concrete part and a holding section with openings for receiving the spacer rod of the spacer.
  • the profile is designed in such a way that the reinforcing rod is between the spacer rod and the guide section can be accommodated in the profile, so that for setting a proper position of the positioning device, the spacer rod can be moved back and forth in the fastening device and the openings of the profile and is fixed in the intended position by means of the wedge element of the spacer on the reinforcing rod.
  • the positioning device according to the third aspect of the invention is preferably used as a stop or spacer bracket in concrete, wood, or metal construction when positioning temporary parts.
  • the positioning device is particularly preferably used in concrete construction when positioning wall formwork to form concrete structures (eg concrete walls).
  • the wedge element according to the first aspect of the invention can be attached to the spacer rod by means of its fastening device, so that it can no longer be lost.
  • the spacer according to the second aspect of the invention can be supplied with the wedge element already attached, which simplifies the work when creating concrete walls.
  • the wedge element can, however, also be supplied individually and serve to equip existing spacers, which do not yet benefit from the invention, with them in order to subsequently simplify the work.
  • Another advantage results from the fact that the main body of the wedge element can be displaced in relation to the fastening device in the direction of the wedge effect and in the opposite direction. This makes it possible to pre-fix the wedge element manually and only then by means of e.g. a hammer to drive to the end position. Prefixing the wedge element is desirable for several reasons. The most important thing is the security aspect; Without the possibility of pre-fixing, the operator must hold the wedge element with one hand and press the hammer to drive it in with the other hand. This can lead to injuries and should therefore be avoided.
  • the wedge element is already in the gap between the reinforcement rod and spacer rod, in other words the wedge element is pretensioned or pre-fixed so that it no longer has to be held when the hammer is finally driven in and the danger described above is eliminated.
  • inserting refers to a force acting on the wedge element which is of the order of magnitude of a force that can be exerted by a person.
  • driving refers to a force exerted on the wedge element with a hammer or a comparable tool, which force is many times higher than the force when it is inserted.

  • the positioning device 8 comprises a spacer 7 with a spacer rod 6 and preferably two stop elements 6a. Furthermore, the positioning device comprises a profile 5 which holds the spacer 7 and is fastened together with it to the reinforcing rod 9 by means of a wedge element 1.
  • the positioning device 8 is arranged in such a way that the stop elements 6a each strike a wall formwork 11, which is best shown in the illustration Fig. 2 you can see.
  • Wall formwork 11 are attached to both sides of the walls 10 and are used to shape the wall 10 when pouring the concrete.
  • the term "intended position” in connection with any element of the inventive devices is understood as that position of the element which contributes to achieving correct positioning of the wall 10.
  • the intended position of the stop element 6a is directly on the wall formwork 11.
  • the intended position of the profile 5 is on the concrete part 12.
  • the profile 5 could also be fastened further up along the reinforcement rod 9, its location on the floor has the advantage that the reinforcing rod 9 is most insensitive to lateral bending in this area and therefore the fastening of the positioning device 8 at this point results in the most precise determination of the position of the wall 10.
  • the wedge element 1 can be retrofitted individually at existing construction sites in one use. In a further application, it can be supplied as part of the spacer 7 mentioned above. Again, a spacer 7 according to the invention can also be part of the positioning device in a further use case 8, which corresponds to a complete solution that can be used immediately for attachment to reinforcing rods 9.
