Station-tunnel combined construction non-column subway station transfer joint structure and construction method
The invention provides a station-tunnel combined construction column-free subway station transfer joint structure which comprises a road tunnel top plate, an upper-layer structural steel beam and a lower-layer structural steel beam. The road tunnel top plate is located above a transverse subway station top plate, the upper-layer structural steel beam is connected to the lower portion of the road tunnel top plate, and the lower-layer structural steel beam is connected to the upper portion of the transverse subway station top plate. A plurality of anti-torque short columns are arranged between the upper-layer structural steel beam and the lower-layer structural steel beam, one ends of the anti-torque short columns are connected with the lower-layer structural steel beam, gaps are formed between the other ends of the anti-torque short columns and the upper-layer structural steel beam, the shear piers are connected with the upper-layer structural steel beam, and one side faces of the shearpiers make contact with one side faces of the anti-torque short columns. By means of the structure, the upper-layer structural steel beam and the lower-layer structural steel beam in the tunnel sidewall portal plane deform independently, stress is simple, force transmission is clear, reinforcement in the upper-layer structural steel beam and the lower-layer structural steel beam is easy, and cracks of the beams at the two ends of the portal are easy to control.
本发明提供一种站隧合建无柱地铁车站换乘节点结构，包括路隧道顶板，公路隧道顶板位于横向地铁车站顶板的上方，上层型钢梁，上层型钢梁连接在公路隧道顶板的下方，下层型钢梁，下层型钢梁连接在横向地铁车站顶板的上方，若干抗扭短柱，抗扭短柱设于上层型钢梁和下层型钢梁之间，抗扭短柱的一端与下层型钢梁连接，抗扭短柱的另一端与上层型钢梁之间具有间隙，若干抗剪墩，抗剪墩与上层型钢梁连接，且抗剪墩的一侧面与抗扭短柱的一侧面相接触，通过本发明的结构使隧道侧墙洞口平面内上下层型钢梁各自独立变形，受力简单，传力明确，上层型钢梁和下层型钢梁内配筋容易，洞口两端梁裂缝易于控制。
