Positioning is installed when assembling, it is tentatively fixed when wedge-shaped opening is assembled for stair ontology construction site, it is convenient for stair ontology construction site
Fast and stable assembles, and effectively improves the security and stability after the assembly of stair ontology；
3, in the utility model balustrade built-in fitting use with the fixed form of stair ontology formed by integrally casting, be effectively ensured
The stability of balustrade built-in fitting occurs connecting unsteady situation after preventing balustrade from installing, stair sheet is effectively ensured
Overall security when body uses；
4, the nail that hangs in the utility model hole for hoist loads and unloads convenient for stair ontology, when loading and unloading stair ontology, need to will only hang
Rope, which is fixed on to hang, to be nailed on, and can be lifted stair ontology by hoisting machinery, 4 lifting points are effectively ensured to stair ontology
Stationarity in hoisting process effectively avoids stair ontology from shaking due to unbalance stress in hoisting process；
5, the drip setting in the utility model is in stair main body downside, effectively prevent stair main body it is water stain along
Stair main body downside flows into metope, while effectively avoiding the water stain dipping to stair main body downside；
Environmental pollution, reduction construction site is avoided to build secondary destruction, safety surely to building in short, the utility model has
It is qualitative it is strong, avoid water stain the advantages of being impregnated to metope.
