Description
Technical Field
The utility model relates to the technical field of assembled steel structure PC external wall panels, in particular to a prefabricated PC external wall panel on-site lifting appliance.
Background
In order to meet the requirements of energy conservation and environmental protection, reduce labor cost and reduce construction waste emission, develop an assembled steel structure and PC building system at full power, develop prefabricated prestressed concrete external wall boards in China and perfect wallboard manufacturing and mounting processes and equipment.
The lifting appliance is mainly used for lifting the prefabricated prestressed concrete external wall panel, the technology of the whole domestic prestressed concrete prefabricated wall panel is almost blank, so that the technology and lifting tool are not mature, the current general lifting rings are used on a few construction sites, the maximum load of the lifting rings is 3 tons at present, the minimum load of the prefabricated prestressed concrete external wall panel is about 13 tons, 6-point lifting is required at least, great difficulty is brought to lifting balance and load distribution, potential safety hazards of unbalanced load lifting object inclination are left, and meanwhile, the safety accidents of object falling and vehicle inclination are caused due to overload fracture of individual lifting points.
The existing lifting appliance is directly stressed by the threads, the threads mainly bear axial force, but when the prefabricated prestressed external wallboard is lifted, the threads need to bear huge shearing force in the lifting process of the wallboard, and thread breakage is very easy to cause.
Because the prefabricated prestressed concrete external wall panel is produced by adopting high-strength prestressed steel wires, the surface tension of the wall panel is very large, so that the design length of the wall panel is longer, two cranes are required to lift and hang in the lifting process, and any lifting point fails to cause the breakage of the whole wall panel.
The international general lifting appliance is more, and a tool suitable for lifting the wallboard is not found yet.
Disclosure of Invention
In order to solve the technical problems, the utility model discloses a prefabricated PC external wall panel on-site lifting appliance.
The specific technical scheme is as follows:
the utility model provides a prefabricated PC side fascia on-spot hoist, prefabricated PC side fascia inside preset reinforcing bar, hoist includes sleeve, connecting plate and high strength bolt; the inner wall of the sleeve is provided with internal threads, the lower part of the sleeve is provided with a through hole, and the steel bar penetrates through the through hole to pre-arrange the sleeve in the prefabricated PC external wall panel; the connecting plate is fixedly connected with the lifting lug, a lifting hole is formed in the lifting lug, and a connecting hole is formed in the connecting plate; the high-strength bolt passes through the connecting hole and then is screwed into the internal thread of the sleeve.
The sleeves are symmetrically arranged at four points on the prefabricated PC external wall panel.
And a gasket is additionally arranged between the high-strength bolt and the connecting plate.
And a plug is additionally arranged between the bottom of the high-strength bolt and the steel bar.
And the connecting plate and the lifting lug are welded in a vertical penetration way.
The high-strength bolt is a 10.9-level high-strength bolt.
Compared with the prior art, the utility model has the following beneficial technical effects:
the lifting appliance provided by the utility model can ensure that wallboards are lifted at a constant speed, cracks and fracture are avoided, and the lifting appliance is easy to balance due to the fact that the stress capability of a single lifting appliance is enhanced, the lifting appliance is symmetrical in 4 points, the bolts are stressed axially, the lifting points are not broken, and the 10.9-level high-strength bolts are used, so that the breakage of the bolts is avoided, and the potential safety hazard is eliminated.
