Concrete upturning beam containing stiff column and construction method thereof
The invention discloses a concrete upturning beam containing a stiff column and a construction method thereof. According to the upturning beam, after pouring of a lower-layer column is completed, a stiff column steel rib is installed on the lower-layer column, then continuous ribs and cut-off ribs are installed, the cut-off ribs are separately connected to the two opposite sides of the stiff column steel rib at a position, cut off by the stiff column steel rib, in the concrete upturning beam, and the cut-off ribs on the third side and the fourth side of the stiff column steel rib are integrated by means of the stiff column steel rib, so that steel bars in the concrete upturning beam form a whole, and the concrete upturning beam is formed by subsequent one-time concrete pouring, and the overall plasticity of the concrete upturning beam is guaranteed. The concrete upturning beam containing the stiff column and the construction method solve the problem that in the upturning beam with the same width as columns and beams of a underground floor slab, the upturning beam with the steel bars blocked by a cross-shaped stiff steel column in a concrete column is formed through one-time pouring, and it is difficult to guarantee the overall plasticity of the upturning beam.
本发明公开了一种内含劲性柱的混凝土上翻梁及其施工方法，该上翻梁在下层柱浇筑完成后，在下层柱上安装劲性柱钢骨，再安装连续筋和截断筋，在混凝土上翻梁内被劲性柱钢骨截断的位置，将截断筋分别连接于劲性柱钢骨的相对两侧，借力劲性柱钢骨将劲性柱钢骨的第三侧和第四侧的截断筋练成一体，使得混凝土上翻梁内的钢筋形成一个整体，以便后续一次性浇筑混凝土形成混凝土上翻梁保证其整体塑性。本发明解决了在地下楼板柱梁同宽的上翻梁中，被混凝土柱内十字型劲性钢柱阻断钢筋的上翻梁一次浇筑成型保证其整体塑性困难的问题。
