Steel truss concrete composite beam bridge support area and construction method
The invention relates to the technical field of bridge structure engineering, and discloses a steel truss concrete composite beam bridge support area, a construction method and a steel truss, and the steel truss comprises an upper chord member, a lower chord member, a web member, a connecting beam and a gusset plate; the bridge deck slab comprises a CA-RPC cast-in-place layer, a two-way reinforcing mesh, an embedded corrugated pipe and a prestressed tendon, and the bridge deck slab is connected with the upper chord member through a shearing force connecting piece; the reinforcing concrete blocks comprise reinforcing concrete, longitudinal steel bars and annular stirrups, the reinforcing concrete blocks are connected with the web members through shearing force connecting pieces, and buffer assemblies are arranged on the side walls of the reinforcing concrete blocks; a protection assembly; the bridge deck slab has the advantages of being high in stability, high in bearing capacity, high in anti-cracking capacity and convenient to construct; the problem that two side plates of the steel truss are squeezed on the current transportation way, and the situation that the corner connecting position is damaged and is prone to oxidation corrosion is avoided, and the transportation convenience of the steel truss is improved.
本发明涉及桥梁结构工程技术领域，公开了钢桁架混凝土组合梁桥支座区及施工方法，钢桁架，所述钢桁架包括上弦杆、下弦杆、腹杆、连接梁和节点板；桥面板，所述桥面板包括CA‑RPC现浇层、双向钢筋网、内埋波纹管和预应力筋，所述桥面板与所述上弦杆通过剪力连接件相连；加固混凝土块，所述加固混凝土块包括加固混凝土、纵向钢筋和环向箍筋，所述加固混凝土块与所述腹杆通过剪力连接件相连，所述加固混凝土块的侧壁设置有缓冲组件；防护组件；本发明该具有稳定性强、承载能力强、桥面板抗裂能力强、施工较为方便的优点；解决了现今运输的路途中会造成钢桁架的两侧板挤压，避免对拐角连接处造成损伤导致容易氧化腐蚀的情况，提高了钢桁架的运输便利性。
