Light sound insulation damping mortar and building construction method

Abstract

The invention discloses light sound insulation damping mortar. The light sound insulation damping motor is formed by mixing 10-50% of inorganic cementing material, 5-50% of rubber, 10-80% of light sand, 1-50% of aggregate and 0.01-20% of additive. A light sound insulation floor is composed of the light sound insulation damping mortar (2) smeared to the top of a concrete floor (1), a protection surface layer (3) smeared on the upper portion of the light sound insulation damping mortar (2) and the light sound insulation damping mortar (2) which is smeared to the upper wall at a wall corner and exceeds the protection surface layer (3).

Description

Technical field: [0001] The invention belongs to the field of building materials and is suitable for thermal insulation and sound insulation treatment of building floors. Background technique: [0002] With the development of economy and society, the requirements for the comfort of buildings are getting higher and higher. Building floors, partition walls, and partition walls are required to have a certain thermal insulation effect and have a certain sound insulation effect. In particular, floors have certain requirements for airborne sound insulation and impact sound insulation. The thickness of residential floors under construction in my country is basically 90-120mm thick reinforced concrete floors, and the standardized impact sound pressure level of floor weighting cannot meet the specification design requirements. . To improve the impact sound insulation performance of the floor, the method of floating floor slab construction is usually adopted, that is, laying a layer ...

Problems solved by technology

In particular, floors have certain requirements for airborne sound insulation and impact sound insulation. The thickness of residential floors under construction in my country is basically 90-120mm thick reinforced concrete floors, and the standardized impact sound pressure level of floor weighting cannot meet the specification design requirements.

To improve the impact sound insulation performance of the floor, the method of floating floor slab construction is usually adopted, that is, laying a layer of elastic cushion (sound insulation cushion) on the concrete floor, laying an insulation layer on the sound insulation cushion, and then pouring fine stone concrete cushion, this technology The solution can solve the requirement of floor impact sound insulation, but there are many cross processes in the project, and the staggered arrangement of electric wires and tubes on the floor makes it difficult to lay the sound insulation mat, which can easily cause the sound insulation mat to be damaged and form a sound bridge, which affects the actual effect
