Bar, two bottom plates, two lower support bars, two wavy shaped configuration plates, two reinforcing bars and multiple damping springs；Under described two
Support rod is vertically arranged in upper support bar both ends respectively, and the upper support bar and two lower support bars form inverted U-shaped structure, described
Two lower support bar lower end surfaces are respectively fixedly connected with a bottom plate upper surface, and two wavy shaped configuration plates are respectively overlay in support
Bar two sides and two lower support bars up and down on two sides up and down, the upper support bar both ends with two wavy shaped configuration plates
And corresponding lower support bar upper end is detachably fixed connection, each wavy shaped configuration plate and upper support bar and two lower support bars
Between be mounted on multiple damping springs, described two reinforcing bar one end are fixedly connected, under two reinforcing bar other ends and two
Post upper one-to-one correspondence is fixedly connected, and two reinforcing bar one end are arranged at below its other end.
The utility model has the beneficial effects that:
The utility model can increase whole bending stiffness and bearing capacity by wavy shaped configuration plate, meanwhile, wave
Shape structural slab reduces the risk of upper support bar and the fracture of lower support bar junction, and structure is simple, supporting effect is good and at two
When lower support bar upper end is squeezed, two reinforcing bars are capable of providing effective support force.
