With social progress, economic development and technological renewal, people's housing needs have changed from home ownership and living space in the past to green, comfortable, livable, healthy and private development, such as the floor structure in housing , not only to meet the needs of heat preservation and energy saving, but also put forward higher requirements for acoustic environment indicators and performance in terms of floor sound insulation and vibration reduction.

"Technical Standards for Residential Performance Evaluation" (GB/T50362-2005), the comprehensive performance of residential buildings reaches 3A level, the sound insulation performance of floors and walls must meet the requirements, the floor-weighted standardized impact sound pressure is ≤ 65dB, and the air-weighted sound insulation volume ≥50dB, and the weighted sound insulation of the household wall is ≥50dB. "Technical Regulations for Construction of Healthy Housing" (CECS179): The recommended weighted standardized impact sound pressure value in 2005 is ≤65dB(A).

The current situation of thermal insulation and sound insulation of household floors is affected by many factors such as building height, structural load-bearing, decoration, etc., especially when the sound insulation treatment is carried out on the residential floor, the actual beneficiaries are the downstairs users. be considered and implemented in construction. If you wait for the house to be delivered for use, and then carry out the thermal insulation and sound insulation treatment of the floor, there will be a situation where the upstairs will benefit from the downstairs, but the contributors will not be able to benefit.

At present, most of the houses provided by developers to users are unrenovated rough houses, and the floor impact sound pressure is very poor, which basically cannot meet the threshold requirements of the regulations. The household floor slab vertically separates the unit components of the upstairs and downstairs users. The activities, noise and vibration of the upstairs will affect the downstairs and the neighbors through the channels of air and structure sound transmission, which will bring inconvenience to the users. The impact of noise and vibration will affect people's health and rational use. The household energy consumption model also puts forward higher demands on the thermal insulation and energy-saving indicators of the floor. How to develop floor slabs that meet thermal insulation, energy saving, sound insulation and vibration reduction, more effectively reduce additional loads, reduce structural thickness, improve headroom, and optimize floor slabs’ functional indicators, etc., is particularly important and urgent.
