Embodiment 1

[0029] A cotton-free non-metallic composite sound barrier of this embodiment is formed by connecting and assembling six barrier monomers 1 with hollow bodies 4 up and down, such as figure 1 As shown (two pieces are shown in the figure), each barrier unit 1 is bonded by a microporous rock-absorbing sound-insulating board 2 and a groove-shaped cement member 3, and the two surround the cavity body 4 in a square shape. cavity. The surface 2 of the microporous rock sound-absorbing and sound-insulating board is in the shape of waves, and of course it can also be in the shape of a flat plate or other shapes. The microporous rock-absorbing and sound-insulating board of this embodiment is 1960 mm long, 400 mm wide, and 15 cm thick. The height of the cavity body perpendicular to the direction of the microporous rock-absorbing and sound-insulating board is 100 mm.

Embodiment 2

[0035] A cotton-free non-metallic composite sound barrier of this embodiment is formed by connecting and assembling six barrier monomers 1 with hollow bodies 4 up and down, such as figure 1 As shown (two pieces are shown in the figure), each barrier monomer 1 is bonded by microporous rock-absorbing and sound-insulating panels 2 and groove-shaped cement components 3, and the two surround the cavity body 4 as a circle shaped cavity. The surface 2 of the microporous rock-absorbing and sound-insulating board is a flat plate. The microporous rock-absorbing and sound-insulating board of this embodiment is 3960 mm long, 500 mm wide, and 25 cm thick. The height of the cavity body perpendicular to the direction of the microporous rock-absorbing sound-insulating board is 140mm

Embodiment 3

[0041] A cotton-free non-metallic composite sound barrier of this embodiment is formed by connecting and assembling six barrier monomers 1 with hollow bodies 4 up and down, such as figure 1 As shown (two pieces are shown in the figure), each barrier unit 1 is bonded by a microporous rock-absorbing sound-insulating board 2 and a groove-shaped cement member 3, and the two surround the cavity body 4 in a trapezoidal shape cavity. The surface 2 of the microporous rock absorption and sound insulation board is a corrugated surface. The microporous rock-absorbing and sound-insulating board of this embodiment is 2000 mm long, 450 mm wide, and 20 cm thick. The height of the cavity body perpendicular to the direction of the microporous rock-absorbing sound-insulating board is 120 mm.

Abstract

The invention relates to a cotton-free non-metallic compound sound barrier and a preparation method thereof. The compound sound barrier is formed by assembling a plurality of barrier single bodies with cavity bodies in an up-down connection mode, each barrier single body is formed by bonding micro-hole rock sound absorbing and insulating boards and groove-shaped cement components, and the cavity bodies are composed of the micro-hole rock sound absorbing and insulating boards and the groove-shaped cement components in an enclosed mode. Production and installation are convenient, connection is conducted without rivets, elegant appearance is achieved, the good sound absorbing property and sound insulating property are achieved, and fire prevention, and weather resistance and durability are achieved. The cotton-free non-metallic compound sound barrier can be widely used in rail way transportation sound insulation, expressway sound insulation, sound insulation of various machines, ceilings, large-sized houses, class rooms and the like. According to the cotton-free non-metallic compound sound barrier and the preparation method thereof, operating humanization and simplification are achieved, maintenance and disassembling are convenient and easy, construction is quick, and manpower and material resources are saved; and meanwhile, the cotton-free non-metallic compound sound barrier can be adaptable to different environment conditions, application prospects are wide, and the cotton-free non-metallic compound sound barrier can be widely used in all industries of the industrial field.

Description

technical field [0001] The invention relates to a cotton-free non-metal composite sound barrier, which belongs to the technical field of noise reduction of sound-absorbing and insulating materials. Background technique [0002] In the noise treatment of some large occasions and urban traffic, the sound barrier has always been the main means of noise control and improvement. When the noise sensitive point is within 60m from the sound barrier, setting up the sound barrier is the main means of noise reduction considerations, especially The sound barrier within 30m has a better noise reduction effect. [0003] At present, in the use cases of sound barriers, there are mainly two types of metal barriers and non-metallic barriers, but both have their shortcomings and problems. Metal barriers are inevitably corroded and rusted by acid rain erosion and wind and sun; among non-metallic sound barriers, for cement board sound barriers, rock wool is now filled in the cavity on the marke...
