Description

iflfrflgei basket

The innovation relates to a connecting stirrup cage for use with concrete components or to a corner reinforcement element consisting of such a connecting stirrup cage and another connecting stirrup cage.

In concrete construction, it is often necessary to provide an overlap joint in the form of corner reinforcement or a corner joint between two concrete elements that are connected to one another at an angle, for example between two adjacent concrete walls that form a corner, in the area of the reinforcement or armouring.

The innovation is based on the task of demonstrating a connecting stirrup cage that, together with another connecting stirrup cage, forms a corner reinforcement element that can be manufactured particularly inexpensively, or a corner reinforcement element of this kind consisting of the two connecting stirrup cages and that can be manufactured inexpensively.

To solve this problem, a connecting bracket cage is designed in accordance with the characterizing part of claim 1 or a corner reinforcement element is designed in accordance with the characterizing part of claim 4.

According to the innovation, one connecting stirrup cage, in which the stirrups are only connected to one another in the area of the yoke sections by the longitudinal bars and the legs of the stirrups are kept free of longitudinal bars, together with the other connecting stirrup cage, which has longitudinal bars connecting the latter to one another at least in the area of the legs of its stirrups, forms the corner reinforcement element. Since the aforementioned other connecting stirrup cage can be manufactured particularly inexpensively from a conventional structural steel mat just by bending, the innovation creates a bending element.

reinforcement element as a corner joint or connecting joint, which can be manufactured inexpensively overall.

In the innovation, the two connecting bracket cages, which are different in terms of the way their brackets are connected by the longitudinal bars, are preferably adapted to one another in such a way that the brackets are provided at the same distance from the longitudinal bars in both connecting bracket cages, so that in the corner reinforcement element obtained by pushing the connecting bracket cages into one another, the legs of the brackets of one connecting bracket cage rest on the legs or the longitudinal bars of the other connecting bracket cage. These legs of the other connecting bracket cage or its longitudinal bars, which are connected to one another by the longitudinal bars, thus at least help to keep the legs of the one connecting bracket cage that are free of longitudinal bars in the required position in a formwork until the concrete is poured.

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

The innovation is explained in more detail below using the figures of an example. They show:

Fig. 1 shows a simplified perspective view of a first connecting stirrup cage for a corner reinforcement or for a corner reinforcement element according to the innovation;

Fig. 2 in a similar representation as Fig. 1 a second connection bracket basket;

Bok reinforcement formed by a stirrup cage .

In the figures, 1 shows a first suspension bracket cage, which consists of several shapeless brackets 2, each of which is made by bending new structural steel or reinforcing steel and has two legs 3 and a crossbar or joist section 4 connecting these legs to one another.

In the area of the yoke section 4, the stirrups 2 are connected to one another by longitudinal bars 5 to form the connecting stirrup cage 1, whereby in the embodiment shown, such a longitudinal bar 5 is welded to the relevant stirrup 2 in the transition area between the yoke section 4 and a leg 3. At least in the immediate area of the longitudinal bar 5, the respective yoke section 4 and the respective leg 3 lie with their longitudinal extension approximately perpendicular to the longitudinal extension of the longitudinal bar 5, ie with a correspondingly rigid design of the stirrups 2 and the longitudinal bars 5 or with a correspondingly large cross-section for the reinforcing steel forming the stirrups 2 and the longitudinal bars 5, the stirrups 2 are ideally provided with their stirrup plane parallel to one another and at a distance from one another.

The connecting bracket cage la shown in Fig. 2 also consists of several brackets 2, each of which is formed by two legs 3 and a yoke section 4 and is connected to one another via the longitudinal bars 5. In addition to the two longitudinal bars 5 running parallel to one another, the connecting bracket cage la also has further longitudinal bars 6 running parallel to the longitudinal bars 5, which cross the legs 3 of the brackets 2 of the connecting bracket cage la perpendicularly and are welded to these legs, i.e. the brackets 2 also connect to one another at the legs 3.

To produce the corner reinforcement in the area of the corner formed by the two concrete walls 7 and 8, the brackets 2 are each essentially in horizontal planes.

arranged connecting bracket basket la, the connecting bracket basket 1 is inserted with the legs 3 of its brackets 2 in such a way that the jog sections 4 of the connecting bracket basket 1 lie in a common vertical plane Bl and the jog sections 4 of the ascending bracket basket la lie in a common vertical plane B2, whereby these planes B1 and B2 enclose an angle with one another, for example an angle of 90°. In addition, the plane El in which the yoke sections 4 of the connecting bracket basket 1 are arranged is adjacent to the legs 3 of the connecting bracket la provided on a common side and the legs 3 of the connecting bracket basket l extend from this plane El through the connecting bracket basket la in such a way that each leg 3 of the connecting bracket basket 1 crosses two legs 3 of the connecting bracket basket la and rests on at least one of these legs 3 of the connecting bracket basket la, whereby the legs 3 of the connecting bracket basket 1 are also held in the desired position until the corner reinforcement formed by the connecting bracket baskets 1 and la is integrated. The legs of the connecting bracket basket 1 extend into the concrete wall 7 and the legs 3 of the connecting bracket basket la into the concrete wall 8.

The connecting bracket cage la can be manufactured in a particularly simple and inexpensive way by bending a structural steel mat, so that the corner reinforcement also has relatively low manufacturing costs overall.
