Vierendeel truss pedestrian overpass
The invention relates to the technical field of open-web type overpass frameworks, and discloses an open-web type truss pedestrian overpass. The main bridge comprises a bridge floor, vertical web members, an upper chord member, a lower chord member, a main bridge pier and a main bridge canopy; the top ends of the vertical web members are connected with upper chords, and the top ends of the upper chords are connected with a main bridge canopy through supports. The bottom ends of the vertical web members are connected with lower chords which are combined with concrete to form a bridge floor, and the two sides of the bottoms of the lower chords are connected with main bridge piers which are fixed to the ground. The end parts of the stairway are respectively connected with the ground and the bridge floor, and a plurality of stairway canopies are arranged at the top of the stairway. The problems that an overbridge is low in space utilization rate, long in construction period and low in passing efficiency, and raindrops splash down pedestrians are solved, and the situations that the occupied area is smaller, the space utilization rate is high, stability is high, and rainwater is prevented from splashing are achieved.
本申请涉及空腹式天桥架构技术领域，公开了一种空腹式桁架人行天桥。上述天桥包括：主桥，主桥包括：桥面、竖腹杆、上弦杆、下弦杆、主桥桥墩以及主桥雨棚；竖腹杆顶端连接上弦杆，上弦杆顶端通过支座与主桥雨棚连接；竖腹杆底端连接下弦杆，下弦杆与混凝土结合形成桥面，下弦杆底部两侧连接主桥桥墩，主桥桥墩固定在地面上；梯道，梯道的端部分别连接地面与桥面，梯道顶部设置若干梯道雨棚。本专利解决天桥空间利用率低、施工周期长、通行效率低以及雨滴溅落行人，达到占用面积更小，空间利用率高，稳定性高以及防止雨水溅射的情况。
