In this embodiment, the connection manner between the adsorption device 2 and the bubble cushion main body 1 is bonding or connection by fasteners, and the lower end of the adsorption device 2 is a vacuum disc to form a vacuum cavity with the plate surface, so that the entire lightweight bubble cushion is tightly adsorbed on the plate surface, reducing the self-weight of the reinforced concrete slab, while maintaining sufficient strength and stiffness. Moreover, the adsorption device 2 and the plate surface are also conveniently positioned through the adsorption force, ensuring that the filling body does not displace during the construction process, improving the construction efficiency and reducing the construction cost.

[0033] Among them, please refer to Figure 1 and Figure 3 As shown, the bubble cushion body 1 is entirely made of polyethylene material. The outer surface of the bubble cushion body 1 is spherical. Of course, the specific shape of the bubble cushion body 1 is not limited. The outer surface of the bubble cushion body 1 can also be an arc surface or a flat surface. However, compared with other shapes, when the outer surface of the bubble cushion body 1 is spherical, it has better strength and stiffness. There are multiple hollow bubbles 4 inside the bubble cushion body 1. When the bubble cushion body 1 is filled with hollow bubbles 4, the density and weight of the material can be further reduced.

[0034] At the same time, 2 pairs of through positioning holes 3 are provided on the outer surface of the bubble cushion body 1. These positioning holes 3 are located at the end of the bubble cushion body 1 close to the adsorption device 2.

When the hollow bubbles 4 are filled inside the bubble cushion body 1, the density and weight of the material can be further reduced.

All the positioning devices and positioning holes 3 are evenly distributed along the axis of the bubble cushion body 1, and the included angle between adjacent positioning holes 3 is 90 degrees. When constructing, first position and connect adjacent lightweight bubble cushions through the positioning device, and then pass the steel bar framework through the corresponding positioning holes 3 of adjacent lightweight bubble cushions, and all lightweight bubble cushions can be connected into a whole.

[0043] Specifically, the positioning device includes a first connecting member 9 and a second connecting member 10. A plurality of mounting holes are arranged at equal intervals on the first connecting member 9, and a positioning post 8 matching the mounting holes is arranged on the second connecting member 10.
