Definitions
- the invention relates to a narrow strip trained flat steel anchors for masonry, on both Ends several in a row, over the Anchor length distributed, flat depressions having.
- These flat steel anchors are located flat between the stones of the masonry, which can be made from any stones e.g. made of sand-lime bricks, gas-concrete blocks or the like Stones.
- the flat steel anchors are in the Grouting the masonry in the mortar or there Binder arranged, preferably in Joint area of the masonry. Because the flat steel anchors predominantly train, it is important that the ends of the flat steel anchor are well fixed, i.e. over have good pull-out strength.
- the flat steel anchor known from GB-A-2143554 has the features of the preamble of claim 1.
- the invention is based on the object at the outset mentioned flat steel anchors so that they have a great pull-out strength and also with small wall thickness a large active cross section along its length in the way that the flat steel anchor a has comparatively high tensile strength. With little Material expenditure should be more resistant to pulling and leaving Flat steel anchors are created.
- depressions at both ends of the flat steel anchor, arranged one behind the other, distributed over the anchor length and wedge-shaped, towards the load of the flat steel anchor are tapered, so that the taper of those located at both anchor ends Depressions towards the middle section of the flat steel anchor shows.
- These depressions form protrusions or depressions, so a form fit with that in the joints of the masonry existing binders to be able to enter.
- the depressions ensure that the active Cross-section of the anchor remains and none Reduce the tensile strength of the flat steel anchor can.
- the depressions can also be made with small holes be provided to avoid air pockets or the like during assembly. to exclude.
- a further increase in the fixation of this anchor can be achieved in that in a row in a row, on the longitudinal central axis of the Flat steel anchors provided recesses alternately be arranged so that a depression on one Side of the flat steel anchor one depression on the other Side of the flat steel anchor follows.
- the flat steel anchor can laterally from two parallel straight edges parallel to each other.
- the side edges are preferably given one Design to increase the pull-out strength of the Anchor contributes. It is particularly useful if the flat steel anchor as a whole over its entire length a wavy or zigzag-shaped floor plan has depressions in one way One side of the flat steel anchor on the other Anchor side opposite, the size of the recess or a lead about a tenth to a sixth of the Flat steel anchor width.
- That e.g. has 1 existing masonry made of sand-lime bricks a longitudinal wall 2 and a transverse wall 3; the Grooves 4 shown enlarged are with a binding or Filled with adhesive.
- a flat steel anchor 5 arranged as a narrow tire is made of stainless steel and with one Half in the wall 2 and the other half in the Transverse wall 3 is arranged so as to mutual To anchor the two walls.
- the depressions 6 are also in the direction the stress is tapered; the tips 9 of the depressions 6 thus point to that Center piece of the flat steel anchor 5, the one about has square depression 6 ', the opposite tips 10 on the ends of the Flat steel anchor 5 show.
- the lateral deflections or projections 12 are comparatively small, but they are just that large that a sufficiently large fixation in the Masonry binders can take place.
- the Indentations - as shown in the drawing - locally on the anchor preferably symmetrically are. If necessary, the depressions can also extend across the entire width of the anchor (e.g. in 6 hatched), but are also the local and the latter depressions in Combination possible.
