The invention discloses a lifting appliance suitable for lifting a concrete product with holes and a lifting method. The lifting appliance comprises a clamp arm, a clamp tooth, a pin shaft, an anti-falling rod and a lifting hook hole. According to the lifting appliance, the component is lifted in the mode that the clamp teeth stretch into the preformed holes to be tightly attached to the inner surface of the component, and compared with the lifting mode that a traditional lifting appliance clamps the two ends of the whole component for lifting, on one hand, the shaking phenomenon of the component in the lifting process can be effectively reduced due to the fact that the contact area of the clamp teeth and the component is increased; on the other hand, due to the fact that the lifting appliance extends into the component, the phenomenon that the component turns over, overturns and even falls off in the lifting process can be avoided, and the safety of lifting operation is greatly improved; according to the lifting appliance, the concrete product with the holes can be lifted only through one reserved hole site, and compared with a traditional lifting appliance which at least needs two clamping points, the operation procedure can be simplified, and the construction efficiency can be improved.
本发明公开了一种适用于带孔混凝土制品吊装的吊具及吊装方法。所述吊具包括钳臂、钳牙、销轴、防脱落杆和吊钩孔。该吊具通过钳牙伸入预留孔贴紧构件内表面的方式来对构件进行吊装,相较于传统吊具夹持构件整体两端进行提升的吊装方式,一方面由于钳牙与构件的接触面积增大,能够有效减少构件在吊装过程中的晃动现象;另一方面由于吊具伸入构件内部,因此可避免构件在吊装过程中发生翻转、倾覆甚至脱落现象,极大提高了吊装操作的安全性;该吊具仅需一个预留孔位即可完成对带孔混凝土制品的吊装,相较于传统吊具至少需要两个夹持点,能够简化操作工序,提升施工效率。
