Noise-reducing and shock-absorbing stair and construction process thereof

Abstract

The invention relates to a noise-reducing and shock-absorbing stair which comprises a foundation frame, a noise-reducing and shock-absorbing fulcrum, an overhead ladder frame and a noise-reducing and shock-absorbing ladder plate. The foundation frame comprises a plurality of bed plates 1 and supporting pieces 2 fixedly connected with the bed plates 1. The noise-reducing and shock-absorbing fulcrum comprises an upper fulcrum plate 3, a lower fulcrum plate 4 and a shock absorbing cushion 5 clamped between the upper fulcrum plate 3 and the lower fulcrum plate 4. The overhead ladder frame comprises a ladder frame body 6 and a plurality of reinforcing ribs 7 fixedly arranged on the ladder frame body 6. The noise-reducing and shock-absorbing ladder plate comprises a basic cement fiber plate 8 and a solid floor 9 fixedly arranged on the basic cement fiber plate 8. The invention further comprises a construction process of the noise-reducing and shock-absorbing stair. The construction process comprises the steps of preparing materials, unloading, erecting, paving and the like. Compared with the current concrete stair in a pouring structure, the noise-reducing and shock-absorbing stair provided by the invention has the remarkable characteristics of sound insulation, noise reduction and shock absorption, and meanwhile the noise-reducing and shock-absorbing stair is light in structural weight, and the bearing load of the floor slabs is alleviated.

Description

technical field [0001] The invention relates to a stair structure mainly used for indoors and its construction technology, in particular to a staircase for reducing noise and stair vibration and its construction technology, which belongs to the field of building stairs. Background technique [0002] At present, the commonly used indoor stair structures are all constructed with concrete pouring and cement bricks. Most of these schemes are designed from the perspective of making the structure more firm and earthquake-resistant. However, in some special occasions, such as auditoriums, theaters and multi-functional halls, the interior design scheme usually has higher requirements for the noise and vibration brought by indoor activities to the indoor space than other occasions. Specifically, reinforced concrete In the application example of combining cement bricks, the impact of noise and vibration generated by personnel activities on the indoor environment cannot meet the ideal ...

AI Technical Summary

Problems solved by technology

[0003] The present invention discloses a new scheme for the noise-reducing and shock-absorbing staircase and its construction technology, which adopts the design of laying a composite wood floor on the steel structure frame to replace the traditional cement pouring scheme, and solves the prominent noise and vibration of the cement board staircase in indoor applications and the problem of high gravity loads on the floor
