AI Technical Summary

Technical Problem

The traditional sound insulation floor is laid inside the concrete floor slab, and the filling material at the column foot is closed, and the overall solid sound transmission results in poor sound insulation effect, high cost, time-consuming and uneven force, and isolation. The sound performance is not outstanding.

Method used

Design an anti-column sound insulation structure on the floor, including a concrete floor slab, supporting steel columns and an upper anti-column sound insulation structure. The upper anti-column foot sound insulation structure consists of a shock-isolating adhesive layer, a steel backing plate, a waterproof layer, column foot concrete parts and reinforced concrete surrounds. Through the design and layout of these components, the separation between the column foot concrete parts and the floor slab is achieved. and shock cushioning.

Benefits of technology

It achieves good sound insulation performance, good structural stability, high shock absorption, low cost, convenient construction, shortened construction time, and is suitable for sound insulation floors of various stages, cinemas, concert halls, etc.

Abstract

A floor upper reverse column foot sound insulation structure comprises a concrete floor, a supporting steel column and an upper reverse column foot sound insulation structure, the upper reverse column foot sound insulation structure comprises a shock insulation rubber layer, a steel base plate, a waterproof layer, a column foot concrete piece and a reinforced concrete surrounding edge, and the shock insulation rubber layer is located under the supporting steel column and arranged on the upper surface of the concrete floor; the steel base plate is flatly laid in the middle of the upper surface of the shock insulation rubber layer, the waterproof layer is fully laid on the upper surface of the steel base plate in a covering mode, the column foot concrete piece is arranged on the waterproof layer in a falling mode, the surrounding edge rubber layer is fully laid on the inner side face of the reinforcing concrete surrounding edge, and the reinforcing concrete surrounding edge and the column foot concrete piece are bonded through the surrounding edge rubber layer. Column foot connecting pieces connected with the supporting steel columns are pre-buried in the column foot concrete pieces, and column feet are sealed through post-pouring sealing bases. The sound insulation floor is good in structural stability, has the characteristics of high sound insulation, high shock absorption and low cost, is convenient to construct, shortens the construction time, and can be used for sound insulation floor parts of various stages, cinemas, music halls and the like.
