Anti-floating structure of overlapped hollow floor with exposed bottom surface and construction method of anti-floating structure
The invention discloses an anti-floating structure of a laminated hollow floor with an exposed bottom surface and a construction method of the anti-floating structure, and belongs to the technical field of hollow floor construction. The anti-floating structure comprises a cavity component, a cast-in-place dense rib beam, a top steel bar layer, a template, a bearing piece, a cushion block, an anti-floating rod and a split bolt; the cavity components are arranged at intervals; the cast-in-place dense rib beams are arranged between the adjacent cavity components; the top reinforcing steel bar layer is arranged on the top surface of the cavity component; the formwork is arranged at the bottom of the hollow floor; the bearing piece is arranged on the top surface of the cavity component; the cushion block is arranged at the top of the bearing piece, and the top face of the cushion block is flush with the top face of the constructed hollow floor system. The anti-floating rod is arranged at the top of the cushion block; the split bolts are arranged corresponding to the cast-in-place dense rib beams, and the tops and the bottoms of the split bolts are fixed to the anti-floating rods and the formworks in a pulling mode respectively. According to the anti-floating rod disclosed by the invention, the anti-floating rod is tensioned with the template through the split bolt, and the counter-acting force is transmitted to the cavity component through the cushion block and the bearing piece, so that the buoyancy generated in the pouring process is counteracted, and the effective position of the cavity component is ensured to be unchanged.
本发明公开了一种底面外露叠合式空心楼盖的抗浮结构及其施工方法，属于空心楼盖施工技术领域，包括空腔构件、现浇密肋梁、顶部钢筋层、模板、承托件、垫块、抗浮杆和对拉螺栓；空腔构件间隔设置；现浇密肋梁设置在相邻的空腔构件之间；顶部钢筋层设置在空腔构件顶面；模板设置在空心楼盖底部；承托件设置在空腔构件顶面；垫块设置在承托件顶部，其顶面与施工完成后的空心楼盖顶面平齐；抗浮杆设置在垫块顶部；对拉螺栓对应现浇密肋梁设置，其顶部、底部分别与抗浮杆、模板拉结固定。本发明的抗浮杆通过对拉螺栓与模板拉紧，并通过垫块和承托件向空腔构件传递反作用力，进而抵消浇筑过程中产生的浮力，保证有效空腔构件的位置不变。
