Description

Technical Field

[0001] The utility model relates to the technical field of assembled wall surfaces, and in particular to an integrated design structure of a wall surface decoration for sound absorption and noise reduction. Background Art

[0002] Noise is the main source of indoor environmental pollution. In order to improve the comfort of living in a building, it is necessary to effectively achieve indoor noise control. In order to improve the sound insulation effect of the interior space of the building, sound insulation cotton is usually set between the facing of the internal partition wall and the base frame. For example, Chinese patent CN202022068233.9 discloses a vibration-reducing and noise-reducing structure for young mice experimental animals, which belongs to the field of vibration reduction and sound insulation technology for buildings. It includes a steel frame, a ground structure layer, a wall structure layer, and a top surface structure layer; the steel frame includes wall columns, a foundation beam layer, a ground overhead steel beam layer, and a roof overhead steel beam layer; the ground structure layer includes an overhead galvanized square tube layer, a patterned steel plate layer, a grouting material leveling layer, a cement self-leveling floor, and a rubber-plastic noise reduction floor; the wall structure layer includes an exterior wall finishing layer, an interior wall panel, a wall sound-absorbing cotton, and a wall sound-absorbing board finishing layer; the top surface structure layer includes a roof panel, a top anti-corrosion wooden keel, a top sound-absorbing cotton, and a top sound-absorbing board finishing layer. It is easy to construct, simple in structure, low in cost, has good sound insulation effect and small vibration impact, and comprehensively reduces the impact of noise and vibration.

[0003] The most common surface decoration material for indoor light steel frame partition walls is veneer board. Even if sound insulation cotton is installed, the noise reduction function of the lightweight partition wall will be reduced due to the transmission of sound through the vibration between the surface board and the base board.

[0047] The outer frame includes a first aluminum alloy profile 5, an L-shaped profile 13, a gasket 11 and a first screw 7. Several first aluminum alloy profiles 5 are spliced ​​to form a rectangular aluminum profile frame. The L-shaped profile 13 is inserted into the end of the first aluminum alloy profile 5. The L-shaped profile 13 is arranged at the corner of two adjacent first aluminum alloy profiles 5. The L-shaped profile 13 is fixedly installed on the first aluminum alloy profile 5 by the first screw 7. The first screw 7 passes through the gasket 11 and the side wall of the first aluminum alloy profile 5 in turn and is threadedly connected to the L-shaped profile 13.

[0048] The first screw 7 is a screw with a length of 10MM and a diameter of 2.5MM. The gasket 11 is a gasket with a diameter of 10MM. The end of the finished semi-arc first aluminum alloy profile 5 is cut at an inner angle of 45°, and four first aluminum alloy profiles 5 are spliced ​​into a rectangular aluminum profile frame. The L-shaped profile 13 is inserted into the cut corner of the first aluminum alloy profile 5, and the two first aluminum alloy profiles 5 at the corner of the rectangular aluminum profile frame are connected by an L-shaped profile 13, and an L-shaped profile 13 is fixed to the two first aluminum alloy profiles 5 respectively through the gasket 11 and the first screw 7.

[0049] The inner frame includes a second aluminum alloy profile 6, and a plurality of second aluminum alloy profiles 6 are spliced ​​together to form an aluminum profile frame whose shape matches the outer frame.

The decorative panel is pre-assembled with the basic frame composed of the outer frame and the inner frame to form a composite and integrated wall decoration surface material, and then installed on the keel as a whole to improve the installation efficiency. A flexible cushion layer is added to the back of the decorative panel, which is the palpable cloth, to reduce the resonance frequency generated by the sound propagation to the decorative panel, thereby achieving the purpose of sound insulation. The wall decoration surface material increases the sound propagation consumption by filling the sound insulation and fireproof rock wool in the basic frame, so as to achieve the sound absorption effect of the decorative structure cavity.
