Lower support adjustable sound barrier beam cast-in-place bridge deck supporting device and cast-in-place construction method
The invention discloses a lower support adjustable sound barrier beam cast-in-place bridge deck slab supporting device which comprises a plurality of main supporting frame units arranged in the length direction of a bridge body and distribution beams erected on the main supporting frame units, and each main supporting frame unit comprises a plurality of steel trusses arranged on the side wall of the upper portion of the bridge body. The roots of the steel trusses are tightly attached to a web of the bridge body, and the inner ends of the steel trusses are fixed to the side of the bridge body through finish rolling deformed steel bars. A fixing pile is fixed to the outer end of each steel truss, an adjusting cross beam is arranged above each steel truss, the outer end of each adjusting cross beam is clamped to the upper end of the corresponding fixing pile, a plurality of adjusting lead screws are vertically arranged on the upper portions of the steel trusses in the width direction of the bridge body, and the upper ends of the adjusting lead screws abut against the adjusting cross beams. The multiple distribution beams are erected at the top of each steel truss in the length direction of the bridge body. The invention further discloses a cast-in-place construction method for a sound barrier beam cast-in-place bridge deck slab through the device. The appearance quality and the construction efficiency of the bridge deck slab in the construction process can be effectively improved.
本发明公开了一种下托可调式声屏障梁现浇桥面板支撑装置，包括多个沿桥梁梁体长度方向布设的主支撑架单元和搭设在其上的分配梁，主支撑架单元包括布设在桥梁梁体上部侧壁上的多个钢桁架，钢桁架根部与桥梁梁体腹板紧密贴合，钢桁架内端部通过精轧螺纹钢固定在桥梁梁体边侧；每个钢桁架外端部均固定有固定桩，每个钢桁架上方设有调节横梁，调节横梁外端卡在对应的固定桩上端，钢桁架上部沿桥梁梁体宽度方向竖直设有多个调节丝杠，调节丝杠上端顶在调节横梁上，多根分配梁沿桥梁梁体的长度方向搭设在每个钢桁架的顶部。本发明还公开了一种利用该装置对声屏障梁现浇桥面板的现浇施工方法。本发明能有效提高施工过程桥面板的外观质量和施工效率。
