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) can be inserted into the gap between the return legs of two flanges of the anchor channel rail, whose head is fixed within the flanges. 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.
  • As known, another common way of attaching other construction elements to a concrete structure is to use an embedded steel part comprising a steel plate with steel re-bars attached to the back. The embedded steel part is cast into the concrete only with the face of the steel plate exposed. The construction element is attached to a set of steel brackets, which are attached in sequence onto the exposed face of the embedded steel part by site welding. Comparatively, the size and weight of the embedded steel part is much larger and heavier than that of the steel channel anchor mentioned above so as to bear the same amount of load. 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.
