Injection-securable anchor and anchor tube for the injection-securable anchor

Abstract

An anchor tube for an injection-securable anchor includes a through-opening (13) for receiving a fastening element (8) and at least first connection element (32) provided on at least first end (14) of the anchor tube (12) for securing, on the anchor tube (12), a further part of the injection-securable anchor (11).

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an injection-securable anchor for attaching a face brickwork to a loadbearing brickwork and, in particular, to an anchor tube for such an anchor and having a through-opening for receiving a fastening element.[0003]2. Description of the Prior Art[0004]An injection-securable anchor is set after raising a two-wall brickwork usually through a joint in the face brickwork, which is also called a face wall, and transmits tension and compression forces acting on the face brickwork to the loadbearing brickwork which is also called a loadbearing wall. Frequent use of such an injection-securable anchor necessitates an additional reconnection of a two-wall brickwork. This is because at a forcelocking connection of both brickworks with each other, due to the corrosion of the connection element that was walled in during formation of the two-wall brickwork, the connection is destroyed.[0005]German Publ...

AI Technical Summary

Benefits of technology

[0011]Anchor tube of different types and lengths and / or sieve sleeves of different types and lengths can be associated to form injection-securable anchor for connecting a face brickwork with a loadbearing brickwork by the user, as needed, directly on the constructional site. An injection-securable anchor that includes an anchor tube according to the present invention is a modular structure. With a small number of differently formed anchor tubes and sieve sleeves, a large number of different constructions of two-wall brickworks can be reliably formed. The injection-securable anchor can be simply and quickly adapted to actual use conditions at the constructional site such as, e.g., stone type, thickness or quality of the loadbearing brickwork and / or the face breakwork, and / or width of the air layer.

[0012]Advantageously, a second connection element provided at a second end of the anchor tube opposite the first end for securing, on the anchor tube, a still further part of the injection-securable anchor. This permits to connect several anchor tubes according to the present invention with each other to bridge a correspondingly greater distance between the face brickwork and the loadbearing brickwork or a very wide air layer. Also a sieve sleeve can be mounted also on the second end of the anchor tube and which in a set condition of the injection-securable anchor, would be located in the face brickwork. This would insure an improved anchoring of the anchor in the face brickwork. The second sieve sleeve makes possible a purposeful anchoring of the anchor in the face brickwork. The above-discussed injection-securable anchor is particularly advantageous when the brickwork has joints with a poor grouting quality. It is particularly advantageous when a sieve sleeve is provided at each end of the anchor tube.

[0016]Advantageously, locking noses are formed at one end of the anchor tube, and locking recesses are formed at the other end of the anchor tube. This insures an easy assembly of several anchor tubes according to the present invention with each other.

[0017]Advantageously, several connection elements are provided at an anchor tube end and which cooperate with a respective plurality of counter-connection elements. The connection devices, which are formed by cooperating connection and counter-connection elements, insure a reliable connection of the parts of the injection-securable anchor with each other.

[0020]Advantageously, the anchor tube is formed of a plastic material. The sieve sleeve, which is connectable with the anchor tube, is also formed, at least in some regions, also of a plastic material. It is particularly advantageous when all parts of an injection-securable anchor are formed of a plastic material by an injection-molding process, which insures a simple production of the connection devices.

Problems solved by technology

This is because at a forcelocking connection of both brickworks with each other, due to the corrosion of the connection element that was walled in during formation of the two-wall brickwork, the connection is destroyed.

The drawback of the anchor tube disclosed in DE 30 04 276 A1 consists in that in practice, different two-wall brickworks with different width of the stone and air layers are raised and, therefore, a large number of differently formed anchor tubes must be available to the user to insure that advantages of such an injection-securable anchor are achieved.
