Problems solved by technology

[0002] The stair formwork acts as a support for the construction unit, and it is constantly vibrated during use, causing fatigue at the welds and the bottom plate, posing safety hazards and easily causing safety accidents
[0003] The application number is CN201710647275.8, which provides a shock-absorbing stair formwork for building construction and its assembly method. This prior art utilizes the sinking of the pedals and then uses elastic components to achieve shock absorption. Although this method can filter out part of the shock, However, for some environments with large loads and rigid impacts, the use of the first-level buffer alone cannot filter out vibrations well, so it will also cause a certain impact on the connection between the stair floor and the wall.

Abstract

The invention provides an assembly type stair damping structure. The assembly type stair damping structure comprises a bottom plate, a top stair plate, a bottom stair plate, middle stair plates, supporting seats and supporting springs I, wherein the top stair plate is arranged at the top of the bottom plate; the bottom stair plate is arranged at the bottom of the bottom plate; at least two middlestair plates are movably connected alternately; the outermost sides of the alternately connected middle stair plates are movably connected with the top stair plate and the bottom stair plate correspondingly; a guide rail on the side surface of the top stair plate is fixedly connected with the supporting seats; the rest supporting seats are connected with the middle stair plates through the supporting springs; every two adjacent supporting seats are connected through a connecting spring; a pedal plate is rotationally mounted on the top surface of each middle stair plate; and an elastic supporting plate is arranged between each pedal plate and the corresponding middle stair plate. By means of rotation of the pedal plates, elastic deformation of the elastic supporting plates, the movement relation between the stair plates movably connected with one another and movement of the supporting seats pushed by the stair plates in the bottom plate, graded damping is formed, and most of impact force can be filtered out.

Description

technical field [0001] The invention relates to the technical field of building stairs, in particular to an assembled staircase shock-absorbing structure. Background technique [0002] The stair formwork acts as a support for the construction unit, and it is constantly vibrated during use, causing fatigue at the welds and the bottom plate, posing potential safety hazards and easily causing safety accidents. [0003] The application number is CN201710647275.8, which provides a shock-absorbing stair formwork for building construction and its assembly method. This prior art utilizes the sinking of the pedals and then uses elastic components to achieve shock absorption. Although this method can filter out part of the shock, However, for some environments with high load and rigid impact, the use of the first-level buffer alone cannot filter out the vibration well, so it will also cause a certain impact on the connection between the stair bottom plate and the wall.
