However, viewing platforms are rarely seen on concrete pedestrian bridges. Therefore, there is a need for a viewing platform that is convenient to implement in terms of both structural processing and installation, has a light weight, and has a relatively small impact on the stress of the pedestrian bridge. In response to the above needs, this utility model proposes a steel structure viewing platform for concrete pedestrian bridges. Utility Model Content

Each first embedded component is horizontally welded with a keel support steel assembly. A clamping component is provided on the left side of the bottom surface of the keel support steel assembly. A bearing I-beam is obliquely connected between the second embedded component and the keel support steel assembly and clamped and fixed by the clamping component. The second embedded component and the bearing I-beam are reinforced by spot welding after clamping. Multiple keel timbers are longitudinally spaced on the top surface of each keel support steel assembly on the same side. Anti-corrosion wooden boards are horizontally laid between each keel timber on the same side. A railing bottom beam is longitudinally provided at the tail end of each keel support steel assembly on the same side. The railing bottom beam is a square tube, and a railing frame body is vertically provided on the top surface of the railing bottom beam.

[0006] A further improvement is that each of the second embedded components includes an arc-shaped embedded plate, and multiple second anchor bars are welded at intervals on the top surface of the arc-shaped embedded plate. A pressure-bearing protrusion is integrally formed on the lower left side of the arc-shaped embedded plate, and a triangular slot is provided on the top surface of the pressure-bearing protrusion for the lower end of the pressure-bearing I-beam to be inserted into the slot.

[0007] A further improvement is that each of the keel support steel groups includes a support steel body, which is made of I-beams, and the top surface of the support steel body is provided with multiple keel brackets at intervals. The left and right sides of the keel brackets are threaded with first clamping bolts for locking and fixing the keel wood after it is inserted.
