Technical Field
[0001] The utility model relates to the technical field of building engineering material hoisting, in particular to a simple assembled prefabricated concrete composite plate hoisting device. Background Art
[0002] In order to meet the requirements of green buildings, most buildings and houses are currently constructed using prefabricated components to increase the engineering assembly rate, and prefabricated composite panels have become the first choice for design. Composite panels can reduce the amount of formwork installation work and labor costs, are easy to construct, and save a lot of costs. Therefore, the current trend in the industry is to use composite panels instead of cast-in-place reinforced concrete slabs.
[0003] The lifting of composite panels is a sub-project with high risks. Most of them are lifted by using lifting equipment such as tower cranes and truck cranes, which hook the composite panel frame steel bars directly through four steel wire ropes. In this lifting method, the composite panel will inevitably tilt and be unevenly stressed during the lifting process, which will lead to cracking of the composite panel, and even extreme cases of fracture, which poses a great safety hazard. There are many composite panel lifting tools at present, but most of them are complex to install and the production process is cumbersome, which wastes a lot of time and cost. Utility Model Content

[0008] The secondary beams are semi-elliptical, two are arranged at each end of the main beam, and the spacing between adjacent secondary beams is 300 mm.
[0009] The damping spring comprises a spring and a protective shell arranged outside the spring, and the spring parameters are φ12*80*240*8N.
[0010] The damping spring, the steel wire rope and the hook are composed of detachable parts.
[0011] The beneficial effects of the utility model are as follows:
[0012] (1) The composite panel lifting device of the utility model is connected to the lifting ring of the device through the lifting hook of the lifting equipment, and the hook is connected to the lifting point of the composite panel to carry out the lifting operation of the assembled precast concrete composite panel.
[0013] (2) The four damping springs of the composite plate lifting device of the utility model are connected to the inner or outer hanging rings, so that the four damping springs are axially symmetrical with the connecting piece as the center. Therefore, the position of the damping springs can be adjusted to meet the lifting operation of composite plates of different sizes.
[0014] (3) The utility model uses four hanging rings and four damping springs to connect the composite plate lifting device during lifting. The resultant force in the horizontal direction is zero, and the resultant force in the vertical direction is vertically upward, which can ensure that the composite plate is evenly stressed, thereby avoiding the extreme situation of cracking and breaking of the composite plate, and ensuring lifting safety.
