Definitions

• the invention relates to a device for fastening a frame to the profile of a laid rail profile strand.
• the object is achieved in that, on the lower part of the rail profile, a holder, which engages under the lower flange and can be locked on it, for easy to produce and easily detachable fastening - in relation to the position of use - directed sideways from the lower flange, in particular essentially horizontally extending support for the frame is provided.
• the device allows a cantilever beam with a defined load direction on existing profile systems, eg. B. rails of tracks to connect quickly and safely to build protection systems for the isolation of hazardous areas, z. B. in the area of a track used in the immediate vicinity. After completion of construction work, this is quickly dismantle and eliminate.
• the attachment of the device to the lower flange of a profile is provided in such a way that the holder of the device is hung on the lower flange of a profile, one in one side of the rail profile in the assembled state of the device Nose engages over the lower flange and, on the side opposite the nose, a clamping unit presses the lower flange of the rail profile against the nose.
• a bolt rotatably mounted in a bearing block is provided for the clamping unit, the bolt being designed such that it is always in engagement with the lower flange of the rail profile in the mounted position on the rail profile due to its lever and weight ratio and thus causes a cement effect .
• the end of the bolt pointing away from the rail profile is designed in such a way that this end generates a torque around the bearing point in the bearing block of the bolt. Furthermore, this end is designed so that it can be gripped by means of fingers or the palm of a hand in such a way that the clamping can be easily released.
• a receptacle is preferably provided on the side of the holder opposite the clamping unit. This receptacle has the advantage that various types of barriers in the form of cantilever beams can be easily attached to it.
