Steel-concrete combined bridge deck prefabricated slab hoisting device without damage to structure
The invention discloses a steel-concrete combined bridge deck precast slab hoisting device without damage to a structure, which comprises a connecting sleeve and a main anchor bar assembly prefabricated in a bridge deck slab, the connecting sleeve and the main anchor bar assembly disassemble and fix a movable lifting lug assembly through a connecting anchor bolt, and a round hoisting hole for hoisting is formed in the lifting lug assembly. A reinforcing assembly for structural reinforcement is further arranged in the lifting lug assembly. The problems that concrete at the root of a lifting lug is broken during lifting and a concrete protection layer cannot be recovered after lifting is completed and the lifting lug is cut due to a temporary lifting point made of traditional HPB300 round steel are solved; the movable lifting lug and the anchor bolt can be repeatedly used, and are economical and environment-friendly; the anchor bar assembly is machined in a factory mode, positioning is accurate, and construction is convenient. The device has wide application prospects in hoisting construction of engineering structure concrete members such as precast slabs, precast beams, precast columns and precast piles.
本发明公开了一种对结构无损的钢混结合桥面预制板吊装装置，包括预制在桥面板中的连接套筒和主锚筋组件，连接套筒和主锚筋组件通过连接锚栓对活动吊耳组件进行拆装固定，所述吊耳组件中形成吊装用的圆形吊孔，所述吊耳组件中还设置有进行结构加强的加强组件。本发明避免了传统的HPB300圆钢制作的临时吊点带来的吊装期间吊耳根部混凝土碎裂、吊装完成切割吊耳后混凝土保护层无法恢复的问题；且活动吊耳、锚栓可重复利用，经济环保；锚筋组件利用工厂化加工，定位精准、施工方便。本发明装置在预制板、预制梁、预制柱、预制桩等工程结构混凝土构件的吊装施工中具有较为广阔的应用前景。
