Description

Device for storing and holding connecting steels for ' concrete components

The innovation relates to a device for inserting into a formwork for a first concrete component Holding and safekeeping of connecting steels to be anchored in this concrete component, the (device) into the formwork insertable, box-like and a lockable opening having storage element, in which the for connection of a second bed component to be connected later serving and by a wall of the storage element connecting steels passed through with a first section are arranged and of which the connecting steels with at least a second section over the wall after stand away from the outside.

Devices of this type are known per se and are used to When producing two concrete components or walls that meet one another, the concrete component initially produced with the one to be connected Concrete component via connecting steels embedded in both connect to. These devices have the advantage that in the formwork, which is necessary for the production of the first concrete component is used, no recesses or breakthroughs for leading the later in the concrete structure to be connected to be embedded sections of the connecting steels provided Need to become. Rather, it is with devices of this type possible to start with a section of the connecting steels in to embed or anchor the first concrete component and then after the formwork has been removed from this bed component in the storage element to expose and bend the housed sections, in order to then embed them in the second concrete component to be connected.

Il lilt

To the ones used to connect the second concrete component To be able to uncover sections, it is necessary when Manufacture of the first concrete component, the interior of the box-like storage element qeqen penetration of concrete or To protect cement clamps.

In known devices with box-like storage elements, this is done in that the corresponding storage element is provided with a removable deck. These Execution is relatively expensive. The removal of the cover also prepares, in particular when the box-like storage element for structural or static reasons has a favorable dovetail cross-section, considerable difficulties.

The particular disadvantage of the known devices is that the first subsections of the arranged in the Veru / ahrungselemen t Connecting steels in the area of the passage through the Wall of the storage element with a relatively small radius of curvature must be bent to an excessively high Avoid design for the storage element. Such a small radius of curvature is particularly large Diameter for the connecting steel is not possible and can lead to major changes in the material when bent open.

The object of the innovation is to avoid this disadvantage. To solve this problem, a device is the The type described at the outset is designed in such a way that the wall of the storage element is bulged outwards at the point where the connecting steel passes.

Due to the design of the device according to the innovation, it is possible to choose the radius of curvature at the bend area of the first sections of the connecting steels to be relatively large, without having to accept an excessively large overall height of the box-shaped storage element at the same time. the

ti i ■ ■ ■

outwardly bulging areas of the wall at the point of passage The connecting steels provide the necessary space for the bent areas of the connecting steels.

In a preferred embodiment, according to the innovation Device also designed so that in the opening of the l'crwahrungsel ementes / to close this opening removable strip made of elastic material is inserted,

This unwanted ingress of concrete or cement slurry preventing strip can be relatively inexpensive and inexpensive are produced and can easily be removed to expose the sections of the connecting steels protected by the storage element. In addition, the strip can be repeated several times can be used, which results in a further cost saving.

In a preferred embodiment, the strip of elastic material takes up the largest possible part of the interior of the storage element. In this case, it is particularly expedient to design the wall of the storage element in the area of the passages of the connecting steel pieces to be arched outwards or drawn forward, in order to create additional free space for the bent area even with a large radius of curvature of the connecting steel pieces bent in the area of these passages, so that the sections of the connecting steels located in the interior of the storage element can be arranged as close as possible to the inner surface of the wall and, with the lowest possible height of the storage element, the greatest possible space is available that can be occupied by the strip of elastic material.

Further developments of the innovation are the subject of the subclaims.

Fig. 2 is a perspective view of a second embodiment of the innovation according to the device, which differs from the Embodiment according to FIG. 1 essentially only through distinguishes a different design of the connecting steels.

The device shown in Fig. 1 consists of a box-like or tub-like storage element 1, which is made in one piece by bending from sheet steel and has a wall forming a bottom surface 2 and side walls 3 on the two longitudinal sides, each with the bottom surface Include an angle less than 90 °, so that the Storage element 1 has a dovetail-shaped cross section results.

The storage element 1 is open or has a reduced cross-section on the side opposite the bottom surface 2 there is an opening 4. Furthermore, in the case of the one shown Embodiment the storage element 1 also on both of them Front sides open. However, it is also possible to close the storage element 1 here by means of each end wall.

A plurality of connecting bars 5 are passed through the bottom surface 2 in a sealed manner at 6, in such a way that the connecting bars 5 have a section 5 'over the outside the bottom surface 2 stand away vertically, while another section 5 "of each connecting steel 5 opposite the associated section 5 'is angled about 90 °, in the interior formed by the bottom surface 2 and the side walls 3

space of the storage element 1 lies and extends essentially parallel to the bottom surface 2, as shown in FIG Fig. 1 is indicated with broken lines.

In order to be able to use the storage element 1 or If the height of the side walls 3 is low, the bending radius in the bent area 5 "', i.e. in the overflow area between the subsections 5' and 5" can be selected as large as possible, is the Ooden area 2 in the area of the passage points 6 of the connecting steels 5 or in the area of the corresponding openings arched on the outside, creating an additional free space inside the storage element 1 for the abaeboaenen area 5 "'of the Connecting steels 5 and the sections 5 ″ thus can lie as close as possible to the inside of the bottom surface 2.

In order to prevent concrete or cement slurry from penetrating into the interior of the storage element when creating the first concrete component, in the form of which the storage element 1 is used and in which this storage element is embedded together with the subsections 5 'of the connecting steel see DAO can be exposed after finishing and stripping of the first concrete structural part, the portions 5 "without difficulty and herausqebogen for connecting a second concrete component, in the interior is of the flashing element 1 between the side walls j is a strip 7 of an elastic material, preferably used from foam rubber which, in the embodiment shown, not only closes the opening 4, but also takes up almost the entire interior space of the storage element 1, which is not filled by the subsections 5 ″.

After completing the first concrete component and after it With the shuttering, the strip 7 can be removed from the relevant storage element 1 through the opening 4 without difficulty, so that the subsections 5 ″ are exposed
