Description
Technical field
The invention belongs to environment protection fields, are mainly used for the ground such as railway two sides, bridge, roadbed, factory circle of plant area, equipment, cell
A kind of square noise reduction, and in particular to cracking resistance soundproof plate.
Background technique
Railway two sides, bridge, roadbed, factory circle of plant area, equipment, cell etc. have the place of noise reduction demand to will be installed soundproof plate
It is heavier to reduce the common sound barrier of noise, especially bridge, roadbed, can additional load, so light-weighted sound barrier is bridge
The common form of beam, roadbed, this kind of light-weighted sound barrier surface density is lower, is generally used in the market by metal outer frame packet
It wraps up in, inside is the areal density soundproof plate that calcium silicate board panel (having hole) and calcium silicate board backboard clip sound absorption cotton, this kind of sound insulation
Plate can reduce noise figure again and reduce the influence to bridge and roadbed, but what the panel and backboard of this kind of soundproof plate used
It is the calcium silicate board of 8-10mm thickness, because structure and function need, panel is to be punched, to realize the need of sound absorption
Ask, but calcium silicate board intensity is low, brittleness is big, timber intensity can be further decreased after punching on plate, in use by
Impact stretches, and in transport or removes when unloading, calcium silicate board is easy to be destroyed, and surface forms crackle or even full wafer fracture, destroys
Soundproof plate reduces durability and the service life of soundproof plate, and later maintenance replacement cost is larger, needs to carry out upgrading processing and improvement.
Summary of the invention
In order to solve the problems, such as that the above lightweight soundproof plate durability is short and the service life is short, the present invention proposes a kind of cracking resistance sound insulation
Plate.A kind of cracking resistance soundproof plate, it is characterized in that being made of metal outer frame, panel, backboard, sound absorption cotton；Panel is evenly distributed with sound-absorption hole, backboard
It is clinged with panel central filler sound absorption cotton blend compounds, the outer periphery of backboard and panel is wrapped up and passes through self-plugging rivet by metal outer frame
It is fixedly connected.
The panel uses polymer composite, and the backboard uses calcium silicate board.
Metal outer frame is folded by steel plate, forms soundproof plate in outermost layer wrap panel backboard and sound absorption cotton, mainly
Internal component is protected, is main support stressed member.
Panel material uses polymer composite, this material is high-intensitive, light, heatproof, corrosion-resistant, insulation, insulate, easily
Processing, easily properties, the macromolecule such as bonding permeate the active force to be formed between molecule, make its formed with remanufactured component Van der Waals force and
Hydrogen bond link, there is excellent adhesive force.Excellent mechanical performance, and there is good machining property and ductility.
Resist chemical performance.The safety of material, 100% solid, material do not have volatility；It is nontoxic, it can directly be connect with skin
Touching；Quality is lighter and then reduces the surface density of soundproof plate.
Soundproof plate panel surface needs aperture according to principle of noise reduction, this soundproof plate selects polymer composite, by
In easy processing, that is, plasticity of material, do not limit to and be fabricated to circular hole, hole shape shape can be optimized under the premise of meeting noise reduction,
Increase the aesthetic feeling on surface.
Calcium silicate board backboard has the advantages that superior fire protecting performance and moisture resistance, service life overlength, is a kind of with excellent
The novel building and industrial sheet of performance, product fire prevention, moisture-proof, sound insulation, Anti-moth-eating, durability are preferable.
Sound absorption cotton selects mineral wool, rock wool or mineral wool as needed, is needed according to scene and Source Spectrum selection is held
Weight and thickness.
The present invention improves the intensity and toughness of soundproof plate, improves durability and the service life of soundproof plate, reduces the later period
The cost of Maintenance and Repair reduces the surface density of soundproof plate, reduces the additional load to support construction.
Detailed description of the invention
Fig. 1 is the elevation of soundproof plate of the present invention.
Fig. 2 is the cross-section diagram of soundproof plate of the present invention.
In figure, 1- metal edge frame, 2- rivet, 3- panel, 4- sound absorption cotton, 5- backboard, 5- sound-absorption hole.
Specific embodiment
Certain Along Railway bridge section, entire bridge are 3.5 kilometers, sound barrier height 3m, span 2m.
Since bridge section is loaded small, in order to guarantee the safety of bridge section, acoustic barrier unit board uses calcium silicate board, is transporting
During, by jolting for vehicle, the rupture for having 5% cell board different degrees of, some even complete breaking releasings are caused into
This increasing.It is to be unloaded removing and receive impact in use process and damage there are also 3%, the rectification before examination causes to do over again, resource
The consumption of cost.This method causes the operation cost of enterprise to increase.
Shown in Fig. 1, Fig. 2, a kind of cracking resistance soundproof plate, it is characterized in that by metal outer frame 1, panel 3, backboard 5,4 groups of cotton of sound absorption
At；Panel 3 is evenly distributed with sound-absorption hole 5, and backboard 5 is clinged with 3 central filler of panel sound absorption 4 blend compounds of cotton, metal outer frame 1 by backboard 5 with
It wraps up and passes through self-plugging rivet 2 and be fixedly connected in the outer periphery of panel 3.
The panel uses polymer composite, and the backboard uses calcium silicate board.
