  • a channel anchoring device made of a metal more particularly, to a channel anchoring device for the construction industry that is manufactured from the material, such as hot rolled steel (or stainless steel), which is suitable to be embedded into a concrete structure or to be attached to a steel structure, to secure other construction elements attached to the structure, and to make the load transferred from the construction elements to the structure.
  • channel anchoring 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the primary objective of the present invention is providing an improved channel anchoring device for the construct industry, which solves the problems that the prior art anchoring device cannot effectively prevent the shift of T-bolt along the channel, and the embedded steel part has larger in size and heavier in weight to cause inconvenience to reinforcement concrete installation.
  • the present invention is a channel anchoring device for the construction industry that comprises a channel rail with a hollow interior and one or more T-bolts, the anchor shaft or steel base plate attached to the exterior surface of the wall of the channel rail, the channel anchoring device with anchor shafts is suitable to be embedded into the concrete structure, while the channel anchoring device with steel base plate is suitable to be welded onto the steel structure, and the T-bolts are inserted into the gap between two return legs of the flanges of the channel rail.
  • the said channel rail with a hollow interior is an anchor channel, preferably manufactured from hot-rolled steel or stainless steel material by the process of hot rolling.
  • the said return legs of two flanges of the anchor channel are separated from each other, the width of the gap there between is slightly larger than the diameter of the shank of inserted T-bolt, the head of T-bolt is locked within the return legs of two flanges of the anchor channel.
  • the anchor channel of the present invention Compared with the prior product of the channel anchoring device for the construction industry, the anchor channel of the present invention has smaller in size, lighter in weight, and prevents the shift of T-bolt along the channel, so as to cause less or even no interference to reinforcement concrete installation.
  • the said anchor channel of the present invention is made by the process of hot rolling.
  • the continuously outspread serrations are designed to arrange on the inner surface of the return legs of the flanges of the anchor channel, which engage with the serrations arranged on the lower surface of the T-bolt head. Therefore, this can prevent the shift of T-bolt along the channel no matter in what orientation the device is placed.
  • the channel anchoring device of the present invention provides much higher shifting resistance than that of the known devices. As a result, the present invention can effectively solve the shifting of T-bolt due to the seismic loading under earthquake condition of greater than Richter scale rating 7 .
  • FIG. 1 is the side view of one embodiment of the channel anchoring device for construction industry of the present invention that is manufactured from hot rolled steel (or stainless steel), which is suitable to be cast into a concrete structure.
  • FIG. 2 is the cross-sectional view of A-A in FIG. 1 .
