Storage housing for wall connection reinforcement steel

The innovation relates to a device for storing several reinforcing bars for wall connection areas of concrete structures, in the form of an elongated box, in which the connecting areas of the reinforcing steel to be bent out are kept, the anchoring areas of which are bent at right angles through a main box wall (Base or cover) protrude.

Such storage devices are attached to the formwork and must after the casting or curing of the Concrete pulled out of the cast concrete structure over the stored connection areas of the reinforcing steel will. With an increasing number of reinforcing bars housed in a storage box, this becomes Pulling out the boxes more difficult and often requires

considerable effort. From DE-PS 2 307 073 it is known to make the storage device from flexible, produce elastically deformable plastic material. Although this makes pulling out easier, difficulties arise with regard to it the shape of the storage boxes with the often high concrete casting pressure, which is why storage boxes made of stiffer, Dimensionally stable plastic is to be given preference.

The innovation is based on the task of finding one that is suitable for accommodating a larger number of reinforcing bars To create storage boxes made of relatively hard, dimensionally stable plastic that is relatively easy can be deducted over the stored connection areas of the reinforcing steel.

To solve this problem, it is provided according to the innovation that the main box wall at the points of passage of the reinforcing steel each has a protruding passage neck towards the anchoring area, its inner and Outer wall surface outwards. rejuvenate. The passage necks are preferably rotationally symmetrical and they have a conical or trough-shaped cross-section.

The passage necks, which have such a length that they even with low storage boxes the area of curvature the reinforcement steel and completely covered opposite the anchoring side, can - With their wide end first - pull it off relatively easily over the bent connecting areas of the reinforcing steel, and they create additional ones at the same time Indentations in the first cast concrete structure, which are particularly good anchoring with the second, to be connected Ensure concrete part.

According to further features of the innovation it is provided that the wall of the passage necks are distributed over the circumference Is provided predetermined breaking points in the form of axially directed grooves, the grooves preferably on the inner wall the passage necks are arranged. On the one hand, these measures result in an extensive seal the penetration points ensured, but the penetration points can when pulling off the reinforcement bars can be expanded considerably by breaking out at the predetermined breaking points. This will make the circumstance takes into account that the several reinforcing bars are usually not bent up exactly parallel and thus thus have differences in distance, which is now taken into account by the expandability of the passage necks is.

The novel device is described in more detail below with reference to two exemplary embodiments shown in the drawing explained. Show in the drawing

1 shows a perspective view of a storage device for five reinforcing bars,

Fig. 2 shows the storage device after pouring into a concrete wall and when preparing its Pulling out of the concrete wall,

3 shows a section through the point of passage of the reinforcing steel through the storage device,

4 shows a modified embodiment of a passage point and

Fig. 5 is a plan view of a passage point.

The storage device consists of an elongated box 1 made of relatively hard plastic, in which angled connection areas 2 of reinforcing steel are added, their bent at right angles Anchoring areas 3 protrude through the box floor 4. The box 1 is made taking advantage of the nailing holes

nailed to a formwork, so that the connection areas are still free in the cavity created by the box 1 after the first concrete wall has been poured. After the casting, the cover 6, which consists, for example, of flexible plastic, is pulled off the box and the connection areas 2 are bent out into a layer 2 '. in which they are directed as straight as possible to the connecting sections of the anchoring areas 3. Then the box 1 is pulled off over the connecting areas 2 and 2 ^{J of} the reinforcing steel.

To facilitate this removal, the points of passage of the reinforcing steel in the box bottom 4 as to Anchoring area protruding through necks 7 formed, the inner wall 9 and outer wall 8 each taper towards the outside. The passage necks are rotationally symmetrical and, in the exemplary embodiment according to FIGS. 1 and 3, have a trough-shaped shape Cross-section on.

In the exemplary embodiment according to FIG. 4, the necks 10 have a conical or conical cross-section.

In both embodiments according to Figures 3 and 4, the passage necks 7 and 10 are each with several over

the circumference distributed predetermined breaking points in the form of axially directed grooves 11, 12 and 13, 14 provided on their inner wall, which here only a relatively thin Leave the remaining wall thickness of the necks.

Fig. 5 illustrates a passage neck 15 at which four grooves forming such predetermined breaking points are arranged in a cross shape. When peeled off, they tear Necks along the predetermined breaking points, so that they are pulled off as a spreading frill over the reinforcing steel can be.

In the exemplary embodiments shown, the passages are arranged on the lower part of the box. she can also be provided on the lid, in which case the storage box with the box bottom on the Formwork must be attached.
