Description

Technical Field

[0001] The utility model belongs to the field of building construction auxiliary equipment, and relates to an assembled concrete hollow sandwich plate hoisting device, which is suitable for hoisting "well" shaped prefabricated components and "cross" shaped prefabricated components. Background Art

[0002] In the 1990s, Professor Ma Jian proposed a reinforced concrete hollow grid structure based on which he replaced the vertical bars of the hollow grid with shear keys. The hollow sandwich plate is composed of four parts: upper ribs, lower ribs, surface concrete plate and shear keys connecting the upper and lower ribs. Figure 1-2 The "well" shaped prefabricated component 1 shown includes a "well" shaped upper rib beam 121 and a "well" shaped lower rib beam 122 arranged at intervals, and each intersection of the "well" shaped upper rib beam 121 and each intersection of the "well" shaped lower rib beam 122 are connected by prefabricated columns 13, and the "well" shaped upper rib beam 121, the "well" shaped lower rib beam 122 and the prefabricated columns 13 together constitute the "well" shaped prefabricated beam 12, and the outer sides of the "well" shaped upper rib beam 121 and the "well" shaped lower rib beam 122 are respectively poured with concrete to form a prefabricated panel surface 11. Figure 3-4 The "cross" shaped prefabricated component 4 shown includes a "cross" shaped upper rib beam 421 and a "cross" shaped lower rib beam 422 arranged at intervals. The intersection of the "cross" shaped upper rib beam 421 and the intersection of the "cross" shaped lower rib beam 222 are connected by a prefabricated column 43. The "cross" shaped upper rib beam 421, the "cross" shaped lower rib beam 422 and the prefabricated column 43 together constitute the "cross" shaped prefabricated beam 42. The outer sides of the "cross" shaped upper rib beam 421 and the "cross" shaped lower rib beam 422 are respectively poured with concrete to form a prefabricated board surface 41. Compared with the hollow grid structure, the shear resistance of the hollow sandwich slab floor is greatly improved; compared with the well-shaped beam floor, it reduces the deadweight of the floor, and at the same time, the hollow part can be used to arrange pipelines; compared with the main and secondary beam floor, it reduces the net height of the floor structure and improves the building volume ratio. The four sides of the "well"-shaped prefabricated component 1 and the "cross"-shaped prefabricated component 4 are used to be connected with adjacent prefabricated components through wet joints at the beam ends. However, these two types of prefabricated components do not have pre-embedded structures such as lifting ears for lifting. When traditional rope lifting and installation are used, there are problems such as great difficulty in lifting and installation, great safety hazards, and irreversible quality damage to the beam-slab-column nodes of the prefabricated components during the lifting process.
