Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] look first figure 1 , figure 1 The standard node schematic diagram of the sound-insulating floating floor of the present invention is shown. It is provided with a shock-absorbing and sound-insulating layer 3 composed of an elastic shock-absorbing sound-insulating pad and a PE plastic film laid thereon on the load-bearing floor 4. In this shock-absorbing A floating layer 2 made of fine stone reinforced concrete is arranged on the sound insulation layer 3 , and a building decoration surface layer 1 is arranged on the floating layer 2 .

[0023] During the construction of the present invention, carry out according to the following mode:

[0024] The first step is to lay polyethylene vibration-absorbing and sound-insulating mats:

[0025] (1) Before laying, the material should be cut according to the specific size of the room and the b...

Abstract

The invention discloses a sound-insulating floating floor surface structure comprising a bearing floor (4) of a reinforced concrete structure. The sound-insulating floating floor surface structure is characterized in that a damping sound-insulating layer (3) composed of an elastic damping sound-insulating pad and a PE (poly ethylene) plastic film paved on the same is arranged on the bearing floor (4), a floating layer (2) composed of fine stone reinforced concrete is arranged on the damping sound-insulating layer (3), and a building decorative surface layer (1) is arranged on the floating layer (2). The reinforced concrete floor serving as a combination of mass and the elastic damping sound-insulating pad is similar to a spring to form a vibration isolation system, the larger the mass of the surface layer is, the better the elastic damping sound-insulating pad is, the better the sound insulation effect is, floor impact sound pressure transmission can be reduced more effectively, and accordingly the sound insulation effect of a floor is improved greatly.

Description

technical field [0001] The invention relates to a method and structure for sound-insulating floating floor slabs, which are suitable for the floors of civil buildings such as high-end villas, high-rise apartments, commercial and residential buildings, and other buildings with sound-insulation design requirements. Background technique [0002] At present, modern commercial and residential buildings require light weight, so the structure is getting thinner and thinner. The general floor thickness is 100-150mm, and its sound insulation effect cannot meet the requirements of "7.1 Noise and sound insulation" in the "Residential Building Code" GB50368-2005 The sound insulation of the floor is one of the important factors to ensure the sound environment of the residence. With the continuous improvement of the people's requirements for the quality of the residence, people require higher and higher sound insulation effects for the living and office spaces. In order to meet people's re...
