It is commonly used as a roof slab, floor slab, platform, wall, retaining wall, foundation, floor, road surface, water tank, etc., with a very wide range of applications. Reinforced concrete slabs are divided into square slabs, circular slabs and special-shaped slabs according to the plane shape, and are divided into one-way slabs and two-way slabs according to the stress action mode of the structure. The most common ones are one-way slabs, four-sided supported two-way slabs and flat slabs supported by columns without beams. The thickness of the slab should meet the requirements of strength and stiffness.

[0023] Specifically, the slide plate 13 is L-shaped, and the cylindrical linear guides 12 are located at both ends of the slide plate 13.
[0024] In this embodiment, the function of the cylindrical linear guide 12 is to support and guide the moving parts to make reciprocating linear motion in a given direction, and it can provide higher load capacity and smaller frictional loss.
