Concrete bracket for a steel-concrete composite beam bridge deck and construction method thereof
The invention discloses a concrete bracket for a steel-concrete composite beam bridge deck. The concrete bracket comprises a steel box girder and a concrete cover plate, the steel box girder comprisesa bottom face and a curved face located on the bottom face, and the edges of the bottom face extend upwards by the same height to form the curved face. The curved surface of the steel box girder comprises two layers, namely an inner curved surface and an outer curved surface; and the concrete cover plate covers the top of the steel box girder. The concrete bracket has the beneficial effects thatin the construction process, the bearing cross beams are used for providing supporting force for the double-pull screws, the double-pull screws drag the flange plates, in this way, a triangular support does not need to be set up to fix the flange plates, welding is not needed in the whole construction process, integral forming is achieved, the construction quality is guaranteed, the construction is convenient, materials of the supporting frame can be repeatedly used, labor is saved, efficiency is improved, and quality is guaranteed.
本发明公开了一种钢混组合梁桥面混凝土托架，包括钢箱梁、混凝土盖板；所述钢箱梁包括底面和位于底面上的曲面，所述底面的边缘均向上延伸同样的高度构成曲面；所述钢箱梁的曲面包括两层，为内曲面和外曲面；所述混凝土盖板覆盖于所述钢箱梁的顶部。本发明的有益效果为：本发明所述一种钢混组合梁桥面混凝土托架在施工过程中利用承重横梁给双拉螺杆支撑力，双拉螺杆拖住翼缘板，这样可以省去搭建三角支架来固定翼缘板，在整个施工过程中无需焊接，一体成型，保证了施工的质量，且施工比较方便、支撑架材料可重复利用，节省了人工、提高了效率、保证了质量。
