The utility model discloses in, the pedestrian passageway support frame sets up on the upper portion of just, the section is encorbelmented to roof beam pile foundation bent cap and bent cap to the upper side, it lays the steel sheet and forms the current interim way of just of supplying the execution workman, it hangs in just the side of roof beam and hugs closely just the roof beam longeron, need not occupy the space of the just bottom of the roof beam of construction, the construction operation space problem of the just bottom of the roof beam of having both solved the construction, solved daily construction operation again, station shunting operation and relevant equipment management unit personnel establish the regional problem that the circuit was kept away the car that carries out in just the roof beam structure. One longitudinal side edge of the pedestrian passageway panel is tightly attached to the side longitudinal beam of the temporary beam, so that the stability of the whole structure and the construction safety can be guaranteed.
Furthermore, in order to ensure the safety of vehicle-avoiding personnel and vehicle-avoiding machines and tools and prevent the personnel and the machines from falling off during vehicle avoidance, the edge part of the upper part of the pedestrian passage support frame is provided with a protective railing.
Further, for guaranteeing pedestrian passageway's support stability, the bent cap is encorbelmented and is provided with the steel bar in section and the just roof beam pile foundation bent cap and be connected with the steel bar, the bent cap encorbelment section with just roof beam pile foundation bent cap concreting is as an organic whole.
The utility model has the advantages that: the utility model discloses a setting up the pedestrian passageway support frame on the upper portion of just, the section is encorbelmented to roof beam pile foundation bent cap and bent cap to lay the steel sheet on it and form the current interim just way of supplying the execution workman, it hangs in just the side of roof beam and hugs closely just the roof beam longeron, need not occupy the space of the just bottom of the roof beam of construction, the construction operation space problem of the just bottom of the roof beam of having both solved the construction, solved daily construction operation again, station shunting operation and relevant equipment management unit personnel establish the regional problem that carries out the circuit and keep away the car just in the roof beam structure. The utility model discloses simple structure through adopting H shaped steel to be the support frame and hug closely its section bolted connection of encorbelmenting with just roof beam pile foundation bent cap and bent cap, pedestrian passageway panel and pedestrian passageway support frame fixed connection, pedestrian passageway support frame and just the side longeron of roof beam, has greatly increased pedestrian passageway's overall stability, has improved the safety in utilization. The utility model discloses simple to operate, the equipment material is more common, and the material can have enough to meet the need the use, is favorable to improving the efficiency of construction and reduces construction cost.

Detailed Description
The invention will now be further described by way of non-limiting examples with reference to the accompanying drawings:
as shown in the attached drawings, the cantilever type portable beam pedestrian passageway comprises a pedestrian passageway support frame 5 formed by two H-shaped steels arranged in parallel, and 400 x 400H-shaped steels can be adopted. The upper portion of people's passageway support frame 5 has laid rather than fixed connection's steel sheet and has been regarded as people's passageway panel 3, adopts the steel sheet of 1cm thick as people's passageway panel 3, and the steel sheet adopts two-sided welding with H shaped steel, should ensure welding quality, guarantees structural integrity. The utility model discloses a section 6 is encorbelmented to human channel support frame 5, the upper portion of section 6 is encorbelmented to the bent cap that pedestrian channel support frame 5 set up just beam pile foundation bent cap 1 and be connected and encorbelment with just beam pile foundation bent cap 1, and the bent cap that the bent cap was encorbelmented section 6 as supporting bracket, and the bolt is passed through respectively to the lower part of pedestrian channel support frame 5 and is connected with just the top of beam pile foundation bent cap 1 and the top that the bent cap was encorbelmented section 6.
