Anti-floating device for formwork of elevator shaft and sump and construction method of anti-floating device
The invention provides an anti-floating device for an elevator shaft and sump formwork. The anti-floating device comprises a reinforced concrete prefabricated slab, and a connecting screw and a hanging ring are reserved on the reinforced concrete prefabricated slab; the reinforcing plates on the box-shaped formwork, the side formworks and the bottom formwork are fixedly connected through internal corner reinforcing pieces, the two internal corner reinforcing pieces on the opposite corners are connected through a main beam, the two opposite reinforcing plates are reinforced through a plurality of horizontal diagonal bracings, and the bottom formwork and the reinforced concrete prefabricated slab are connected through connecting screws and opposite-pull screws. The invention further provides a construction method of the anti-floating device for the formwork of the elevator shaft and the sump. By arranging the reinforced concrete prefabricated slab and the box-shaped formwork, the device forms a stable formwork reinforcing system and an anti-floating structure, the anti-floating effect is good, in addition, the top of the box-shaped formwork does not need to be ballasted, deformation and potential safety hazards of the suspended formwork are effectively prevented, the pouring forming quality and the construction quality are guaranteed, and the construction efficiency is improved. And the implementation of other procedures is not influenced.
本发明提供一种电梯井、集水坑模板防上浮的装置，包括钢筋混凝土预制板，钢筋混凝土预制板上预留有连接螺杆和吊环；箱形模板，侧模和底模上的加固板通过阴角加固件固定连接，对角两个阴角加固件之间通过主梁连接，相对两个加固板之间通过多个水平对撑进行加固，底模与钢筋混凝土预制板通过连接螺杆和对拉螺杆实现连接。本发明还提供一种电梯井、集水坑模板防上浮的装置的施工方法。本发明通过设置钢筋混凝土预制板和箱形模板，使装置形成稳定的模板加固体系和抗上浮结构，抗上浮效果好，另外箱形模板顶部不需要压重，有效防止导致吊模模板变形和安全隐患，保证了浇筑成型质量和施工质量，不影响其他工序的实施。
