Description

Technical Field

[0001] The utility model relates to the field of beam-column joint connection structures, and specifically relates to a floor thermal insulation and noise reduction structure. Background Art

[0002] In recent years, with the improvement of domestic living standards, people's requirements for the thermal insulation and sound insulation performance of residential building floors have become higher and higher. The country has also paid more and more attention to this issue and has successively issued national standards such as the "Code for Sound Insulation Design of Civil Buildings" GB50118 and the "Green Building Evaluation Standard" GBT50378. These standards have put forward relatively high requirements for the thermal insulation performance and sound insulation performance of building floors.

[0003] At present, most of the new floor thermal insulation and sound insulation structures of buildings adopt a floating structure. The floating structure is to lay a thermal insulation and sound insulation board on the structural floor slab, and pour a reinforced fine aggregate concrete or lightweight aggregate concrete thermal insulation layer on the insulation board as a protective layer. The periphery of the protective layer is isolated from the wall with sound insulation materials to form a structure that is both thermally insulated and sound insulated. However, using sound insulation materials for sound insulation, the effect still cannot completely achieve sound insulation. Therefore, we propose a floor thermal insulation and noise reduction structure. Content of the Utility Model

[0004] In view of the problems in the prior art, the utility model provides a floor thermal insulation and noise reduction structure.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a floor thermal insulation and noise reduction structure, including a floor slab layer and a floor tile layer, characterized in that: a thermal insulation layer is arranged above the floor slab layer, a sound insulation layer is arranged above the thermal insulation layer, a vacuum groove is opened inside the sound insulation layer, and an air extraction valve is installed on the outer wall of the sound insulation layer;

[0006] Specifically, L-shaped plates and C-shaped plates are symmetrically fixed inside the vacuum groove opened inside the sound insulation layer;

[0007] Specifically, the L-shaped plates are fixed at the four corners of the sound insulation layer, and the C-shaped plates are located between the two L-shaped plates;

[0008] Specifically, ventilation holes are opened on the side walls of the L-shaped plates and the C-shaped plates;

[0009] Specifically, the L-shaped plates and the C-shaped plates divide the vacuum groove opened inside the sound insulation layer into a cross-shaped groove and a rectangular groove;

[0010] Specifically, a cross-shaped plate is fixed on the inner side wall at the upper end of the cross-shaped groove, and a rectangular plate is fixed on the inner side wall at the upper end of the rectangular groove;

[0011] Specifically, the L-shaped plate, the C-shaped plate, the Feng-shaped plate and the rectangular plate are all made of steel;

[0012] Specifically, the thermal insulation layer is an aluminum silicate thermal insulation material;

The air extraction valve is started by electric control to extract the air in the vacuum groove. The sound passes through the vacuum groove. Since there is no transmission medium, the sound cannot be transmitted, thereby achieving a good noise reduction effect.
