Improved stair structure with noise reduction function
The invention relates to an improved stair structure with the noise reduction function. The improved stair structure comprises L-shaped footboard bodies. A horizontal plate of each L-shaped footboard body is provided with a plurality of threaded holes I, the ends of a vertical plate of each L-shaped footboard body are horizontally provided with connecting plates, and the connecting plates are provided with threaded holes II matched with the threaded holes I. Every two L-shaped footboard bodies are connected through cooperation of bolts, the threaded holes I and the threaded holes II. The end face of the horizontal plate of each L-shaped footboard body is provided with a plurality of fixing columns, fixing holes are formed in the fixing columns in the axial direction, and plastic balls are arranged in the fixing holes. The L-shaped footboard bodies and the connecting plates are made of hard aluminum alloy. The improved stair structure solves the problems that the length of an existing wood stair cannot be adjusted according to the actual height, using the stair is limited, and heavy noise pollution is produced in the pedaling process.
