Abstract

The present invention relates to a C-shaped anchor rail for anchoring hammer-head screws, hook-head screws, wall connection anchors or the like, with anchor webs arranged in a wedge shape to the axis of symmetry, openings (4) being present in the anchor webs (3). This makes it easier to press the anchor channel into the not yet hardened concrete.

Description

The invention relates to a C-shaped anchor rail for anchoring hammer head screws, hook head screws, wall connection anchors or the like on concrete structures.

Anchor channels are fastened to a formwork using a nail or screw connection before concreting a concrete structure, or the anchor channels are subsequently pressed into the not yet hardened concrete structure after the concrete has been poured into a formwork.

The second connection method is used in particular in the manufacture of concrete slabs, such as soundproof walls or the like.

In order to ensure a better load transfer of the anchor channel to the concrete structure, the anchor bars of the anchor channels are not aligned parallel, but wedge-shaped to the axis of symmetry.

A disadvantage of this connection method, however, is that voids can form in the concrete on the outside of the wedge-shaped anchor webs when the anchor channels are pressed into the not yet hardened concrete structure.

The object of the invention is to avoid this known disadvantage and to disclose an anchor rail in which these cavities cannot arise when the anchor rail is introduced into the concrete structure.

For this purpose, the invention is characterized by the features mentioned in the main claim.

Several exemplary embodiments of the invention can be seen from the subclaims.

The invention relates to a C-shaped anchor rail ( 1 ) for anchoring hammer-head screws, hook-head screws, wall connection anchors, where the anchor bars ( 3rd ) wedge-shaped to the axis of symmetry ( 2nd ) are arranged.

In the anchor bars ( 3rd ) are breakthroughs ( 4th ) available.

About the breakthroughs ( 4th ) the liquid or not yet hardened concrete ( 5 ) from the inside ( 6 ) the anchor bars ( 3rd ) to the outside ( 7 ) the anchor bars ( 3rd ) flow when the anchor channel ( 1 ) vertically from above into a flat, not yet hardened concrete body ( 8th ) is pressed.

Through the breakthroughs ( 4th ) to the outside ( 7 ) the anchor bars ( 3rd ) flowing concrete ( 5 ) hollow spots on the outside ( 7 ) the anchor bars ( 3rd ) safely avoided.

The anchor bars ( 3rd ) can be equipped with one or more baffles ( 9 ) be connected. Through the baffles ( 9 ) more of the uncured concrete ( 5 ) through the breakthroughs ( 4th ) pressed when the anchor channel ( 1 ) vertically from above into the concrete ( 5 ) is pressed.

This effect is particularly effective when the baffles ( 9 ) with the side walls ( 10th ) the anchor bars ( 3rd ) are connected, and with you in cross-section ( 11 ) an obtuse angle ( 12th ) form.

The anchor bars ( 3rd ) and possibly also the baffles ( 9 ) are with the side walls ( 14 ) the C-shaped anchor channel ( 1 ) connected.

The anchor rail ( 1 ) can be made of two anchor rail halves connected in mirror image ( 15 ) that exist via a connection point ( 16 ) or via a separate connecting part ( 17th ) are positively and / or non-positively connected.

The separate connecting part ( 17th ) fills the interior ( 18th ) the C-shaped anchor channel ( 1 ) practically completely and the mirror-image arranged side walls ( 10th ) and the separate connecting part ( 17th ) are formed by a connecting link designed as a tensioning band, form clamp, spring clamp, plastic molded part, solder wire or the like ( 19th ) positively and / or non-positively connected.

The separate connecting part ( 17th ) can be made from a wooden material ( 20th ), a molded plastic part or the like and it is in cross section ( 21 ) made in one piece or it consists of a middle part ( 22 ) and two side parts ( 23 ).

The top ( 24th ) the C-shaped anchor channel ( 1 ) is from a continuous masking ( 26 ) covered so that no concrete ( 5 ) possibly on the top ( 24th ) can contaminate existing gearing.

The separate connecting part ( 17th ), the upper part ( 27 ) of the two anchor bars ( 3rd ) and if necessary the continuous masking ( 28 ) are of a connecting link designed as a tensioning strap or the like ( 19th ) positively and / or non-positively connected.

In the procedure for installing the anchor channel ( 1 ) in a building ( 8th ) concrete ( 5 ) the anchor channel ( 1 ) vertically from above with the anchor bars ( 3rd ) first so far into a liquid or not yet hardened building structure ( 8th ) concrete ( 5 ) pressed until the top ( 24th ) the C-shaped anchor channel ( 1 ) with the surface ( 25th ) of the liquid or still plastic structure ( 8th ) concrete ( 5 ) completes or is at a height.

In the 13 is an anchor channel ( 1 ) with particularly slim anchor bars ( 3rd ) shown so that this anchor channel ( 1 ) can be placed well in the concrete even with very tight reinforcement.

As the 14 shows, the anchor bar ( 3rd ) as a baffle ( 9 ) be trained.
