Definitions

  • the invention relates to a device for storing reinforcing steel for connection areas of concrete structures in the form of an elongated, essentially strip-shaped body, in which bending-out connection areas of the reinforcement steel are embedded, the anchoring areas of which protrude from a wide longitudinal surface of the body.
  • Such a device is known from DE-B-2503742.
  • the reinforcing steels are embedded in a storage device, which is designed as a strip-shaped foam body. If a connection area of a concrete structure, such as a T-shaped butt joint, is to be made between an already finished concrete wall and a concrete wall that starts at a right angle from it, the connection areas of the reinforcing steels are required after the storage device has been poured into the first completed concrete wall bend out and completely remove the foam.
  • the reinforcement steels themselves must be completely free of foam, otherwise an inadequate connection between steel and concrete will result. This requires some work, since the foam is held in place by the reinforcing steel and can only be scraped out in small parts.
  • the invention is therefore based on the object of providing a storage device of the type mentioned at the outset which, after being poured into a concrete structure, can be removed simply and with little expenditure of time.
  • the body comprises an open box in the wide longitudinal surface, on the bottom surface of which are arranged in the transverse direction at longitudinal intervals, the slits in the upper region substantially transverse to their longitudinal direction
  • the connection areas of the reinforcing steel and that the lower box can be closed by a cover penetrated by the anchoring areas.
  • the storage device is thus formed by an open box which can be closed by a lid construction and which can be pulled off essentially with one hand from a concrete construction which receives the anchoring areas of the connecting steels.
  • Another advantage is that the box can also be manufactured and sold as such, so that it can be used to hold different types of reinforcing steel or can be purchased from specialist companies that only bend and insert the reinforcing steel. This loading is a simple and clean process. There is no need to remove any escaping foam from the storage.
  • the cover elements can have corresponding recesses on their mutually facing edges for receiving the reinforcing steel.
  • the slots in the retaining strips which are located opposite each other at the two ends of the retaining strips, are preferably designed as pocket slots entering from only one side, so that they can receive and support the bent and protruding anchoring areas of the reinforcing steel.
  • the dividing lines between the cover elements are expediently in the longitudinal center lines of the holding strips.
  • the remaining slots in the central area of the retaining strips preferably have an X-shaped cross section and widen on both sides from a narrower central area, so that the connecting areas of the reinforcing steel, which will be removed later, are laid at an acute angle to the longitudinal axis of the strip in a criss-cross manner can.
  • the reinforcing steel must be held in the slots of the retaining strips, it is expedient to form the slots, viewed in the vertical section, with undercuts, for example in the form of an 8, so that two reinforcing steel bars lying one above the other can be held with a certain clamping effect.
  • the lower box and the cover elements can consist of thin material in the form of foils or plates.
  • the holding strips are preferably glued to the bottom and the side walls of the lower box.
  • a storage device shown in FIG. 1 and designated overall by 10 serves to hold reinforcing steels 12, 14, 16, 18, 20, which overall have the shape of a U-shaped bracket and moreover, in the vicinity of their closed end, perpendicular to Are angled.
  • Such reinforcement steels are used to connect structural parts made of concrete, which are cast in two successive steps.
  • the closed storage device 10 is placed with its surface lying in FIG. 11 against the formwork, so that the areas of the reinforcing steel 12, 14, 16, 18, 20 protruding from the device 10 , which are to be referred to as anchoring areas 22, protrude into the interior of the formwork and are anchored in the concrete mass.
  • connection areas 24 are included in the formwork of the subsequently poured concrete part, so that a reinforcement connection is created between the two concrete parts. Further details on the use of the device according to the invention will be explained later with reference to FIGS. 6 to 8.
  • the device 10 comprises a flat, strip-shaped lower box 26 with a bottom 28, side walls 30 and 32 and end walls, not shown.
  • a number of holding strips 34 which are parallel and spaced apart and have slots 36 which enter from above and run transversely to the holding strips.
  • a slot 38 is provided on both ends of the retaining strip, which only enters the retaining strip from one side and from above and is to be referred to as a pocket slot.
  • the outer slots 38 serve to accommodate the angled transitions between the connecting areas 24 and the anchoring areas 22 of the reinforcing steel .
  • the anchoring areas 22 protrude from the slots 38 perpendicular to the device 10 and emerge from the device 10 upwards.
  • the lower box 26 can be closed by a number of cover elements 40, which are essentially divided in the longitudinal center lines of the retaining strips 34, so that in each case an anchoring area 22 of the reinforcing steel between two cover elements 40 can emerge from the device.
  • cover elements 40 which are essentially divided in the longitudinal center lines of the retaining strips 34, so that in each case an anchoring area 22 of the reinforcing steel between two cover elements 40 can emerge from the device.
  • semicircular recesses 42, 44 are provided on the mutually facing edges of the cover elements 40, which each complement one another to form circles and allow the legs of the anchoring regions 22 to be received. Therefore, the lower box 26 can be closed essentially tightly by the cover elements 40.
  • locking pins 46, 48 are provided on the underside of the cover elements, which snap into correspondingly arranged locking bores 50, 52 in the retaining strips 34 and hold the cover elements in the closed position.
  • the connecting areas 24 of the reinforcing steel lie in the slots 36 of the retaining strips 34 in an arrangement running at an acute angle to the longitudinal axis of the lower box 26, so that the reinforcing steel can be provided in relatively close succession without mutually inside the storage device hinder. So that the connecting areas 24 can be laid crosswise in the slots 36, the slots 36 have a sufficient depth to accommodate two superimposed connecting areas 24, as can be seen, for example, from FIG. 2.
  • the slots 36 according to FIG. 4 preferably have an X-shaped cross section, which widens from the central area to both sides.
  • the outer slots 38 which serve to receive the angled transition areas between the connecting areas 24 and the anchoring areas 22, can include an undercut inner holding area 54 and a funnel-shaped opening area 56 in the horizontal cross section.
  • the holding area 54 causes the protruding legs of the anchoring area 22 to be clamped in place.
  • the funnel-shaped opening areas 56 allow the connection areas 24 to exit at an acute angle to the longitudinal center line of the lower box 26.
  • the slots 36 and 38 according to FIG. 2 also have undercuts in the vertical section, so that an 8-shaped sectional view can result, for example according to FIG. 2, provided that two connecting areas 24 are to be laid one above the other.
  • separation slots 58, 60 are also indicated, which enter the holding strips 34 from above and allow a certain elastic deformation of the parts of the holding strips 34 which act as clamping jaws.
  • the retaining strips 34 can be made of elastic plastic, and the slots 36, 38 can with respect to the dimensions of the Reinforcing steels must be dimensioned such that the reinforcing steels must be pressed into the slots with a certain pressure and are held by these clamps.
  • FIG. 4 shows a side view of the device 10 with the anchoring regions 22 of the reinforcing steels protruding therefrom. It can be seen that the connecting areas of the reinforcing steels, not described here in more detail, lie in two layers one above the other in the lower box 26.
  • FIGS. 4 to 8 An example is a T-shaped butt joint between two concrete walls that are poured in two successive steps.
  • one of the concrete walls, which is labeled 62 is poured.
  • the device 10 according to the invention lies within a formwork designated 64, 66 in a vertical arrangement, the bottom surface of the device resting against one of the formworks 66. In this position, the anchoring areas 22 of the reinforcing steels protrude into the concrete matrix, so that they are anchored in the concrete wall 62.
  • the bottom of the device 10 is accessible from the outside. Since the retaining strips 34 with the respective slots 36, 38 only grip the reinforcement bars from the bottom side, the entire storage device can usually be removed from the cast-in anchoring areas 22 and the connecting areas 24 with one hand. The connecting areas 24 are then bent out of the concrete wall 62 vertically in the usual manner, as illustrated in the upper part of FIGS. 7 and 8, and after the appropriate formwork has been produced, the subsequent concrete wall can be poured.
  • connection areas 24 during the pouring of the first concrete wall 62 as shown in the lower illustration in FIG., Lie within the device 10 and thus within the formwork 66, it is not necessary to destroy the mostly reusable formwork 66 by drilling.
  • the lower box and the cover elements can consist of thin film-like plastic material, since the arrangement of the holding strips 34 and the reinforcing steel clamped in them results in a sufficiently load-bearing construction.
  • retaining strips 34 were described which were designed as solid strips with slots or notches. However, such an implementation is not necessary. There are also constructions made of wire, steel strip or the like, which, although they follow the contours of the slots and thus allow the reinforcement steels to be accommodated, are otherwise not massive. What is essential is only holding members directed transversely to the longitudinal direction of the lower box, which enable the reinforcing steels to be clamped in and at the same time keep them at a distance from one another and in the desired position.
  • the lid also allows various modifications. It is only essential that the cover allows passage of the emerging anchoring areas of the reinforcing steel.
  • the cover can be placed as a closed unit with slots and / or cutouts for receiving the anchoring areas or in the form of individual elements. If necessary, it can also be connected in a hinge-like manner to an upper free longitudinal edge of the lower box, as is the case in the example described. Otherwise, the design of the cover can also be based on the shape of the anchoring regions, which do not have to have the U-shape explained above, but can have any bending shape suitable for anchoring and also do not have to be connected in a bow-shaped manner.
  • the lid can be closed by spot welding. Adhesive strips, Velcro fasteners or the like can also be used.
