Formwork-free pouring concrete bottom plate structure of steel-concrete composite beam and construction method of formwork-free pouring concrete bottom plate structure
The invention discloses a reinforced concrete composite beam formwork-erecting-free pouring concrete bottom plate structure and a construction method thereof.The bottom plate structure comprises a concrete top plate and corrugated I-shaped steel, and the bottom faces of the two transverse sides of the concrete top plate are fixedly connected to upper flange plates of the corrugated I-shaped steel arranged in parallel respectively. A lower flange plate of the corrugated I-shaped steel is fixedly installed on the prefabricated corrugated combined bottom plate, the prefabricated corrugated combined bottom plate is provided with a bottom plate steel shell and concrete, a side flange plate is arranged on the top face of the bottom plate steel shell, and a corrugated cavity/corrugated table and a bolt shear key are arranged on the inner wall of a concave groove cavity of the bottom plate steel shell. High-strength bolts are arranged in the internal thread sleeves and the bolt holes in a penetrating manner to fixedly connect the lower flange plate and the side flange plates; the bottom plate steel shell is connected with the corrugated I-shaped steel lower flange steel plate through the high-strength bolts, the section rigidity is improved, the problem that a concrete bottom plate is prone to cracking is solved, the bottom plate steel shell serves as a formwork for concrete bottom plate pouring, formwork erecting is avoided, and the construction period is shortened.
本发明公开了一种钢混组合梁免支模浇筑混凝土底板结构及其施工方法，底板结构包括混凝土顶板和波纹工字钢，混凝土顶板横向两侧底面分别固定连接于平行设置的波纹工字钢的上翼缘板，其特征在于，波纹工字钢的下翼缘板固定安装于预制波纹组合底板上，预制波纹组合底板设置有底板钢壳和混凝土，底板钢壳的顶面设置有侧翼缘板，底板钢壳的凹型槽腔内壁上设置有波纹腔/波纹台和螺栓剪力键，在内螺纹套筒和螺栓孔内穿设高强螺栓固定连接下翼缘板和侧翼缘板；将底板钢壳通过高强螺栓与波纹工字钢下翼缘钢板连接，增加截面刚度，解决混凝土底板容易开裂的问题，作为混凝土底板浇筑的模板，避免模板搭设，缩短工期。
