Pre-embedded hoisting box, prefabricated slab and hoisting and connecting method of prefabricated slab
The invention discloses an pre-embedded hoisting box, a prefabricated slab and a hoisting and connecting method of the prefabricated slab. The pre-embedded hoisting box comprises a hook inlet, two limiting grooves with downward openings and an elastic device, wherein the lower end of the hook inlet communicates with the openings of the limiting grooves; the limiting grooves are formed in the opposite positions of the two sides of the hook inlet respectively; the elastic device is arranged at the bottom of the pre-embedded hoisting box; the hook inlet is used for allowing an external hoisting hook to enter the pre-embedded hoisting box; and the elastic device is used for providing upward elastic force to jack the hoisting hook into the two limiting grooves after the hoisting hook enters thepre-embedded hoisting box and makes contact with the elastic device. According to the invention, by means of the pre-embedded hoisting box and the matched hoisting hook, after the prefabricated slabis hoisted to a designated position, the hoisting hook can be conveniently taken out of the pre-embedded hoisting box, so that cutting of a hoisting ring is avoided, the construction progress is accelerated, the construction safety is enhanced, and creation of a civilized construction site is facilitated.
本发明公开了一种预埋吊装盒、预制板、预制板的吊装和连接方法。其中，所述预埋吊装盒包括进钩孔、两个开口向下的限位槽和弹性装置；所述进钩孔的下端与所述限位槽的开口相连通，所述进钩孔的两侧的相对位置分别设置一个所述限位槽，所述弹性装置设置于所述预埋吊装盒的底部；所述进钩孔用于供外部的吊钩进入所述预埋吊装盒；所述弹性装置用于在所述吊钩进入所述预埋吊装盒内部与所述弹性装置接触后，提供向上的弹力将所述吊钩顶进两个所述限位槽。本发明通过预埋吊装盒和配套的吊钩，能够在预制板吊装至指定位置之后，方便地将吊钩取出预埋吊装盒，避免了切割吊环，加快了施工进度，加强了施工安全，有利于文明工地创建。
