Improved stair structure with noise reduction function

Abstract

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.

Description

technical field [0001] The invention relates to the field of building construction tools, in particular to an improved structure of stairs with sound-absorbing effect. Background technique [0002] In building construction, in order to facilitate the operation or to carry objects to the upper floors, or to facilitate the movement of workers, stairs are generally used. The stairs used in construction are different from the stairs in the building. The stairs in the building are the most vertical communication components between floors. They are used for traffic connections between floors and when the height difference is large. The main requirement is structural stability. The stairs used are mainly to facilitate the transportation of objects or the walking of construction workers. The main requirement is that they are practical and flexible. [0003] The stairs used in the existing construction process generally adopt traditional I-shaped stairs made of wood. The existing w...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an improved staircase structure with sound-absorbing effect, so as to overcome the fact that the existing wooden staircase cannot adjust the length of the staircase according to the actual height, so that the use of the staircase is limited, and there is a relatively large noise during the stepping process. big noise pollution problem
