[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The lightweight concrete slab involved in this utility model includes a concrete slab body in the shape of a cuboid, and a steel reinforcement skeleton is embedded in the concrete slab body. The steel reinforcement skeleton includes a number of first steel bars that extend horizontally to the left and right and are parallel to each other, second steel bars that extend horizontally to the front and back and are parallel to each other, and third steel bars that extend vertically to the top and bottom and are parallel to each other.

[0005] At the intersection of any of the third reinforcing bars and a set of intersecting first and second reinforcing bars, a hollow material-saving ball is provided. The material-saving ball has a first through hole that passes through from left to right, a second through hole that passes through from front to back, and a third through hole that passes through from top to bottom. The first reinforcing bar passes through the first through hole, the second reinforcing bar passes through the second through hole, and the third reinforcing bar passes through the third through hole.

[0006] The present invention is further configured such that: the first reinforcing bar and the material-saving ball are connected by spot welding; the second reinforcing bar and the material-saving ball are connected by spot welding; and the third reinforcing bar and the material-saving ball are connected by spot welding.

[0007] The present invention is further configured such that the material-saving ball is made of stainless steel.

[0008] In summary, the present invention has the following beneficial effects: The lightweight concrete slab involved in the present invention, by setting material-saving balls at the intersection of three steel bars, not only serves as a connection between them, but also saves material locally, achieving a local hollow effect, reducing the overall weight of the concrete slab, achieving a certain lightweight effect, with complete overall function and strong practicality.

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See Figures 1 to 5 As shown, the lightweight concrete slab involved in this embodiment includes a rectangular concrete slab body 100, and a steel reinforcement skeleton 200 is embedded in the concrete slab body 100. The steel reinforcement skeleton 200 includes a plurality of first steel bars 201 that extend horizontally to the left and right and are parallel to each other, second steel bars 202 that extend horizontally to the front and back and are parallel to each other, and third steel bars 203 that extend vertically up and down and are parallel to each other.

[0018] At the intersection of any of the third reinforcing bars 203 and a set of intersecting first reinforcing bars 201 and second reinforcing bars 202, a hollow material-saving ball 204 is provided. The material-saving ball 204 has a first through hole 205 that passes through from left to right, a second through hole 206 that passes through from front to back, and a third through hole 207 that passes through from top to bottom. The first reinforcing bar 201 passes through the first through hole 205, the second reinforcing bar 202 passes through the second through hole 206, and the third reinforcing bar 203 passes through the third through hole 207.
