Definitions
- the invention relates to a foundation anchor according to the preamble of claim 1.
- Foundation anchor used where steel strands or cables around suitable deflection elements be performed. These arrangements are in holes introduced, the holes grouted with cement mortar and prestressed the steel strands. After use, the Strands or cables are pulled out so that only one small amount of metal remains in the ground.
- a foundation anchor of this kind is in EP-A-577 421.
- this solution is relatively complex in the manufacturing process as they are specially designed prepared deflection elements required.
- each deflecting element thus at least one U-shaped, rod-shaped Steel element made of reinforcing iron.
- the steel element is connected to the deflecting element, e.g. by welding.
- At least one flexible is around the deflecting element Tension element placed.
- the deflecting element is preferably a half cylinder made of metal, as it is easily made from a halved round bars can be made.
- each Deflection element two reinforcement bars placed between which is guided at least one tension element. So serve the reinforcing iron as a force dissipation, but also for guiding the tension element.
- each deflection element can be arranged one after the other, with each Deflection element at least one tension element and a steel element is placed. To make the most efficient use of space and to achieve even force distribution, can be turned against each other be arranged.
- the Foundation anchoring a metal tube, which axially at least over the area of the deflection element or elements extends.
- the metal tube is preferred corrugated in the transverse direction so that it is good after longitudinal forces can transmit outside.
- the foundation anchor can be made by halving a round bar to serve as a deflecting element to serve. Then bent steel element on the round bar welded. These steps can all be done on the Construction site with existing tools and materials be performed.
- FIGs. 1-7 The basic structure of a preferred embodiment the foundation anchor is shown in Figs. 1-7. This Figure shows only the lower one, i.e. earth end of Foundation anchor. This end rests in a hole 1 that is grouted with cement mortar. The mortar fills everyone Cavities inside and outside the anchor.
- Each strand is in a U-shaped loop each placed around a deflection element 6, 7, 8.
- the deflection elements are massive half cylinders in the present version made of metal, the curved side of which is at the bottom.
- each deflection element 6, 7, 8 are also two reinforcing bars 9a, 9b, 10a, 10b and 11a, 11b, respectively.
- the reinforcing bars 9a, 9b, 10a, 10b and 11a, 11b are U-shaped, rod-shaped steel elements, whereby the two legs are parallel to the longitudinal axis of the anchor from the deflection elements in the direction of the upper anchor end extend.
- the curved part of the reinforcing iron lies on the curved surface of the respective deflecting element and is welded to it (see FIG. 7).
- the task of the reinforcing iron is part of the forces acting on the deflection elements record and transfer to the environment.
- the three deflection elements 6, 7, 8, the three Strands 2, 3, 4 and the reinforcing bars are against each other each rotated by 120 °. This creates the space in the hole 1 better used and the forces become even distributed.
- the lowest reinforcing bars 9a, 9b are shorter than the top reinforcement bars 11a, 11b, this because the upward forces are increasing.
- the foundation anchor is equipped with a tube 12 that from lower anchor end at least over the three deflection elements or even extends to the top of the anchor.
- the pipe 12 consists of metal, preferably steel, and has, as shown in Fig. 8, one in the longitudinal direction substantially sinusoidal wavy coat. It it turns out that such a coat is able also high forces in the surrounding mortar and soil derived without damaging the Rohrs is coming.
- the tube 12 straps the deflection elements and thereby acts on the radial forces and their Counter explosive effect. It stabilizes the foundation anchor in the longitudinal direction, causes an even distribution of the thrust and serves to maintain the maximum Anchor diameter.
- the pipe ensures that the Anchor is approximately centered in hole 1 and on all sides surrounded with a sufficiently thick mortar coat is.
- the foundation anchor according to the present version can be made in a simple manner.
- the Deflection elements 6, 7, 8 are halved in length Round bars made and welded with the reinforcing bars. Then the strands 2, 3, 4 over the deflection elements placed and the three deflection elements are in the tube 12 inserted.
- the foundation anchor thus completed can now be pushed into hole 1 and with mortar be pressed. Then the strands are at the top of the anchor biased.
