Channel

Abstract

A channel anchoring device (100) having predetermined structural properties, for securing construction elements to a metallic structure, the anchoring device (100) comprising a generally elongate metallic channel rail (110) having an engagement surface for engagement with a fastener, the fastener providing fixation of a construction element to the channel rail (110), and a generally elongate metallic fixation member (120) abutted against and engaged with said channel rail (110), wherein the fixation member (120) is engaged with the channel rail (110), said fixation member being formed from a material suitable for allowing welded fixation of the anchoring device (100) to a structure. The fixation member (120) and the channel rail (110) are engaged by a riveting process such that the predetermined structural properties of the channel rail (110) are not altered by heat generated during the riveting process; and the fixation member (120) is sized such that the predetermined structural properties of the channel rail (110) are not altered by heat generated from welding of the anchoring device (100) via the fixation member to a structure.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a channel device formed from a metal or metallic material for the fixation of construction elements thereto, generally for the construction industry. More particularly, the present invention relates to fixation of a channel device to a structure.BACKGROUND OF THE INVENTION[0002]Various channel devices of conventional type are known that are manufactured by the process of die casting, cold rolling, or hot rolling, which comprise a channel rail having a hollow interior and one or more anchor shafts attached thereto. Channel devices, as known within the prior art, are attachable to a structure, such as a concrete or steel structure, and allow the fixation of other construction elements, such as panels thereto, so as to engage the construction elements with the structure.[0003]The anchor shafts attached to the exterior surface of the web of the channel and embedded into the concrete. A T-shape bolt (hereinafter called T-bolt) ...

AI Technical Summary

Benefits of technology

The solution provides a secure, heat-resistant, and efficient method for fixing construction elements to metallic structures, maintaining structural integrity under high loads and environmental factors while adhering to building codes, ensuring safety and reducing production costs.

Problems solved by technology

Since the inner surfaces of both the T-bolt head and the channel wall are smooth, such type of anchoring device cannot effectively prevent a shift of the T-bolt along the channel.

Moreover, the channel anchor shafts of above mentioned type are normally larger in size and may sometimes conflict with the reinforced concrete installation, in particular with the outermost layer of steel reinforcement bars.

Moreover, the steel re-bars required on the embedded steel part are also more in quantity and longer in length and thus causing much more interference to reinforced concrete installation.

Furthermore, such channels must be securely fixed to the structure so as to ensure that the construction elements are maintained in place, and that environmental factors such as moisture, rain, high wind forces, seismic activity, do not compromise the integrity of fixation, as loosening of construction elements may have severe consequences to surrounding persons and property.
