Description

A fireproof sound-absorbing partition wall structure

Technical Field

The utility model relates to the technical field of sound-absorbing partition walls, in particular to a fireproof sound-absorbing partition wall structure.

Background Art

Partition walls are components that divide spaces and are a type of non-load-bearing wall. Generally speaking, there are several types of partition wall materials: lightweight bricks, glass bricks, glass, wood, gypsum boards, etc. Partition wall types can generally be divided into: Brick partition walls: non-load-bearing walls built with ordinary clay bricks, hollow bricks, aerated concrete blocks, glass bricks and other block materials; Folding rib partition walls: lightweight partition walls composed of a skeleton and a finishing layer, including slat plastering partition walls, steel mesh plastering partition walls, various plate partition walls, light steel keel gypsum board partition walls, etc.; Folding plate partition walls: also called slat partition walls, partition walls assembled with large pieces of slats. This type of high-partition partition wall generally does not use a skeleton, and sometimes vertical keels can be set to improve its stability. The panels used for partition walls are generally strip panels equal to the net height of the room, which are usually divided into composite panels, single material panels, hollow panels and other types. Common ones include metal sandwich panels, gypsum sandwich panels, gypsum hollow panels, Taibai boards, reinforced cement polystyrene boards (GRC boards), aerated concrete strips, cement ceramsite boards, etc.

The functions of modern buildings are becoming more and more diverse, and the requirements for separation and control between different areas are becoming higher and higher. As the main means of building separation, after the partition is completed, some traditional partition materials, such as bricks and gypsum boards, have certain fire resistance, but their sound absorption effect is often poor, which is difficult to meet the high requirements for the acoustic environment in modern buildings. In addition, although some new sound-absorbing materials have excellent sound absorption performance, their fire resistance may be insufficient, resulting in poor fire resistance of the partition in a fire.

Please refer to Figures 1-3, a fireproof sound-absorbing partition wall structure includes a wall 1, a first sound-absorbing panel 2 is arranged on the right side of the wall 1, shock-absorbing hanging weights 3 are arranged on both sides of the upper and lower sides of the right side of the first sound-absorbing panel 2, expansion bolts 4 are penetrated on both sides of the upper and lower sides of the shock-absorbing hanging weights 3, and the other end of the expansion bolts 4 penetrates the first sound-absorbing panel 2 and extends to the inside of the wall 1, two cement fiber boards 6 are arranged on the right side of the first sound-absorbing panel 2, and a second sound-absorbing panel 8 is arranged on the right side of the cement fiber board 6. The second sound-absorbing panel 8 includes a perforated protective panel 81, a glass cloth 82, a sound-absorbing material 83 and a frame 84, the perforated protective panel 81 is arranged on the outermost side, the glass cloth 82 is arranged on one side of the perforated protective panel 81, the sound-absorbing material 83 is arranged on the side of the glass cloth 82 away from the perforated protective panel 81, and the number of the frame 84 is two, and they are both arranged above and below the perforated protective panel 81, the glass cloth 82 and the sound-absorbing material 83.

The upper and lower sides of both sides of the right side surface of the second sound-absorbing panel 8 are threadedly connected with fastening bolts 9, and the other end of the fastening bolts 9 passes through the cement fiber board 6 and is used in conjunction with the inside of the first sound-absorbing panel 2, so that the second sound-absorbing panel 8, the hollow layer 7 and the first sound-absorbing panel 2 are conveniently connected and fixed.

A hollow layer 7 is provided between the left and right cement fiber boards 6, and the thickness thereof is 8 mm to 12 mm, so that the sound waves are reflected twice during the propagation process, thereby increasing the attenuation of the sound waves, thereby greatly improving the sound insulation effect.

The sound-absorbing material 83 is made of ultra-fine glass wool, and the perforated protective panel 81 is made of galvanized plate or aluminum plate. The ultra-fine glass wool has extremely high thermal resistance and low thermal conductivity, which can effectively prevent heat transfer and improve thermal insulation performance. At the same time, since the fibers inside the ultra-fine glass wool are distributed in three dimensions, they can effectively absorb sound wave energy, thereby reducing noise generation. In addition, through the setting of the galvanized plate, it can effectively resist corrosion, making the product less likely to rust, thereby extending its service life.

Grooves 5 are provided on both sides of the upper and lower sides of the right side of the first sound absorbing board 2, and the shock-absorbing hanging weight 3 is located inside the groove 5, so that the cement fiber board 6 can be better fitted with the first sound absorbing board 2 to improve the sound absorption effect.

The frame 84 is a light steel keel, which has good tensile, compressive and bending strengths and can withstand greater loads and pressures.

Working principle: When in use, through the setting of the cement fiber board 6, it is specially treated and has good fire resistance, which can effectively prevent the spread of fire and achieve the effect of fire prevention. Through the setting of the perforated protective panel 81, the glass cloth 82 and the sound-absorbing material 83, the ultra-fine glass wool has extremely high thermal resistance and low thermal conductivity, which can effectively prevent the transfer of heat and improve the thermal insulation performance. At the same time, due to the three-dimensional distribution of the fibers inside the ultra-fine glass wool, it can effectively absorb sound wave energy, thereby reducing the generation of noise. And through the setting of the galvanized plate, it can effectively resist corrosion, making the product not easy to rust, thereby extending the service life. In a high temperature environment, the glass cloth 82 shows excellent stability and durability, and is not easy to deform or burn.
