The through-hole for anchoring suspension cable is provided on the otic placode.
Further, the steel anchor slab and the molding of otic placode overall processing.
Further, the transverse steel in girder passes through some or all of through-hole, and the PBL for forming tape punching reinforcing bar, which is sheared, to be connected
Connect key part.
Further, the through hole installation hinge pin connector and suspension cable anchorage head.
Further, one piece of stiffening plate is respectively installed in the otic placode two sides.The stiffening plate has through-hole corresponding with through-hole, uses
In improving intensity near lug plate holes, guarantee anchoring safety.
Further, the plate face of the steel anchor slab welds several pegs, forms Welded-Stud Conectors.
It is worth noting that suspension cable is anchored in concrete girder by the steel anchor plate type cable beam anchoring structure of the utility model
Top guarantees that steel anchor slab and beams of concrete cooperate by shear connector inside girder, can give full play to steel tension
Intensity height and the good feature of concrete anti-compression performance, avoid concrete cable beam anchorage structure problem easy to crack.Due to avoiding
Suspension cable passes through the working procedure of girder, when using steel anchor plate type cable beam anchoring structure, hanging cable construction, the later period inspection of suspension cable
Repairing and replacing all becomes to be more easier.Meanwhile steel anchored framework weld seam can effectively solve steel construction far fewer than anchor tie plate structure
Fatigable problem.
