Reinforced concrete structural slab reinforcing method
The invention relates to a method for reinforcing a reinforced concrete structural slab, which comprises the following steps of: 1) mounting a post-added steel beam below the existing reinforced concrete structural slab according to a conventional method; (2) an upper bracket bearing plate, a lower bracket bearing plate and limiting angle steel are installed on a lower flange of the post-added steel beam and connected together through high-strength bolts, and therefore the assembly type steel structure bracket is formed; (3) a limiting plate is welded to the position above the junction of the upper bracket bearing plate and the web of the post-added steel beam; (4) a thin jack is installed on the upper bracket bearing plate, the thin jack is used for jacking the post-added steel beam downwards, and therefore a gap is formed between the post-added steel beam and the reinforced concrete structural slab; (5) steel plate cushion blocks are inserted into the gaps; (6) the remaining gaps are filled with high-strength polymer mortar; and (7) the thin jack is disassembled, the high-strength bolts are loosened, and the assembly type steel structure bracket is disassembled. According to the reinforcing method for the reinforced concrete structural slab, the problem that the later-added steel beam and the existing reinforced concrete structural slab cannot be cooperatively stressed is solved.
本发明涉及一种钢筋混凝土结构板加固方法，1)、按照常规方法，在既有钢筋混凝土结构板下安装后加钢梁；2)、将上托架承板、下托架承板、限位角钢安装在后加钢梁的下翼缘上，并通过高强螺栓连接在一起，从而形成装配式钢结构托架；3)、将限位板焊在上托架承板与后加钢梁腹板交界处上方；4)、在上托架承板上安装薄型千斤顶，利用薄型千斤顶将后加钢梁往下顶，从而在后加钢梁和钢筋混凝土结构板之间形成间隙；5)、在间隙中，插入钢板垫块；6)、采用高强聚合物砂浆将剩余间隙填充满；7)、卸下薄型千斤顶，松开高强螺栓，并卸下装配式钢结构托架。本发明的一种钢筋混凝土结构板加固方法解决了后加钢梁无法与既有钢筋混凝土结构板协同受力的问题。
