Cast-in-place box girder formwork support structure and construction method
The invention discloses a cast-in-place box girder formwork support structure and a construction method, and belongs to the technical field of bridge construction. Comprising a bottom frame, a plurality of formworks are obliquely arranged on the bottom frame, a plurality of supporting assemblies used for supporting the formworks are arranged on the bottom frame, and each supporting assembly comprises a supporting beam abutting against the outer surfaces of the formworks and composed of a plurality of cross beams and longitudinal beams, a building frame welded to the bottom frame, a push rod sliding on one side of the building frame in the horizontal direction and a driving mechanism, and one end of the push rod is hinged to the push rod for pushing the push rod to slide. According to the device, the push rods are driven by the driving mechanism to slide, so that the push rods extrude the supporting beams inwards, the overall structural strength of the supporting beams is improved through the arrangement of the cross beams and the longitudinal beams, and therefore after the supporting beams abut against the surfaces of the formworks, the high-strength supporting effect can be provided for the formworks, the formworks are not prone to deformation, and the forming quality of flange plates is guaranteed.
本发明公开了现浇箱梁支模架结构及施工方法，属于桥梁建设技术领域。包括底架，底架上倾斜设置有若干模板，底架上设置有若干用于支撑模板的支撑组件，支撑组件包括：支撑梁，抵接于模板外表面且由若干横梁和纵梁组成，搭架，焊接于底架上，推杆，沿水平方向滑动于搭架一侧且一端与纵梁固定，驱动机构，铰接于搭架上且一端与推杆铰接，用于推动推杆滑动。通过本发明,通过驱动机构驱动推杆滑动使得推杆向内挤压支撑梁，横梁和纵梁的设置提高了支撑梁的整体结构强度，从而使得在支撑梁抵紧模板表面后，能对模板提供高强度的支撑效果，使得模板不易发生形变，保证了翼缘板的成型质量。
