The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

Example 1 Unit-type stepping Module 23

As shown in fig. 17-20, a unit type tread module 23 for horizontal, left and right vertical casting is composed of an integrally formed tread plane 231 and tread vertical face 232, and a plurality of unit type tread modules 23 are spliced to form the whole tread mold 2.

The lower end of the stepping vertical surface 232 is provided with a sliding hole 233 extending in the longitudinal direction, specifically, the lower end of the stepping vertical surface 232 is provided with a vertical surface extending surface 2321, and the vertical surface extending surface 2321 is provided with a plurality of sliding holes 233. The end of the tread plane 231 is provided with a connecting hole 234 for matching with the sliding hole 233 of the adjacent unit tread module 23. Specifically, the end of the tread plane 231 is provided with a connection surface 2311 parallel to the vertical surface extension surface 2321, and the connection surface 2311 is provided with a plurality of connection holes 234 for matching with the sliding holes 233 of the adjacent unit tread modules 23.

When the end plane of tread surface 231 is aligned with the lower end of slide hole 233, the end plane seals slide hole 233 on the adjacent cellular tread module. Specifically, when the connecting hole 234 is aligned with the lower end of the sliding hole 233, the connecting surface 2311 seals the sliding hole 233 of the adjacent unit step module, i.e., the distance from the connecting hole 234 to the upper edge of the connecting surface 2311 is greater than the length of the sliding hole 233 in the longitudinal direction.

This arrangement has the following advantages: (1) when the limiting piece 235 penetrates through the sliding hole 233 and is located at the lowest end of the sliding hole 233, the upper end of the sliding hole 233 is also blocked by the connecting surface 2311, so that the sliding hole 233 is not exposed by adjusting the step height, and the integrity of the pouring stair is ensured; (2) the connecting surface 2311 has a certain width, so that the tread plane 231 and the tread vertical surface 232 are in surface contact, rather than in line contact between plates and surfaces, thereby ensuring that only sliding operation is performed between one unit tread module 23 and the adjacent unit tread module 23 under the action of the limiting member 235, and the deflection angles are consistent and no deviation is generated.

The connecting hole 234 is used for detachably mounting a limiting member 235, and under the action of the limiting member 235, the vertical surface extension surface 2321 and the connecting surface 2311 are attached together to prevent the adjacent unit-type stepping modules 23 from being separated from each other during rotation, but can move up and down along the sliding hole 233 in the longitudinal direction, so that the stepping height can be adjusted. Meanwhile, the sliding hole 233 and the connecting hole 234 are fixedly connected together by the limiting member 235, and after the angle of one unit type stepping module 23 is adjusted, the other unit type stepping modules 23 all have the same angle after adjustment, and a certain unit type stepping module 23 does not have angle change due to factors such as external force or vibration. Particularly, the structure of the vertical casting mold is more stable.

An outer chamfer mould 236 is further arranged at the end of the tread plane 231, namely the upper edge of the connecting surface 2311, the outer chamfer mould 236 is integrally formed with the tread plane 231 and is used for fitting the tread vertical surfaces 232 of the adjacent unit tread modules 23, and therefore the corner of the poured stair is chamfered.
