Description

A kind of automatically cleaning road acoustical panel
Technical field
The present invention relates to a kind of automatically cleaning road acoustical panels, belong to road technical field of sound isolation.
Background technique
With the development of road traffic and urban construction, vehicle bring noise problem is got worse, and has seriously affected road The daily life of road both sides resident endangers the health of people, in order to which the noise for generating vehicle does not influence road both sides Resident, it will usually acoustical panel be set in road both sides, traffic noise can be stopped to road ambient radiation.
Existing road acoustical panel is composed of noise-reducing structure and supporting construction mostly.Common acoustical panel is with rock wool layer For main noise-reducing structure, hard plate is supporting construction, adds some connections and sound-silencing measures.This noise reduction plate structure is complicated, It vulnerable to pollution and is difficult to clean, influences the erasure effect and beauty of acoustical panel.
Summary of the invention
It is an object of that present invention to provide a kind of simple structure, it is easy for construction, solve existing noise reduction convenient for clean acoustical panel Plate structure complexity, difficult cleaning of disadvantage.
In order to realize above-mentioned target, the present invention provides a kind of following scheme: automatically cleaning road acoustical panel, the acoustical panel by Each noise reduction plate unit is sequentially connected with composition, and noise reduction plate unit is by the first fiber concrete slab 1,2 groups of the second fiber concrete slab At the surface of the first fiber concrete slab 1 and the second fiber concrete slab 2 contains hole, and the overall thickness of noise reduction plate unit is not small In 200mm.
The inner surface of first fiber concrete slab 1 is equipped with trapezoidal groove 3, and the inner surface of the second fiber concrete slab 2 is overhanging There is trapezoidal concrete block 4, overhanging trapezoidal concrete block 4 and trapezoidal groove 3 are matched and can be closely joined together, two pieces of fibres It ties up concrete slab and one noise reduction plate unit, two pieces of fiber coagulations is spliced by overhanging trapezoidal concrete block 4 and trapezoidal groove 3 The size of native plate is identical;When acoustical panel unit spliced, the first fiber concrete slab 1 is outside relative to the second fiber concrete slab 2 The groove of a longitudinal direction is deviated, the groove of the longitudinal direction is as the connection knot between other noise reduction plate units and the noise reduction plate unit Structure.
Penetrating tubaeform hole is densely covered on first fiber concrete slab 1 and the second fiber concrete slab 2, first is fine Tubaeform hole on dimension concrete slab 1 and the second fiber concrete slab 2 is opened on one both sides of composition when noise reduction plate unit assembles The small bloop 5 broad in the middle of mouth, bloop 5 are uniformly distributed on noise reduction plate unit.
First fiber concrete slab 1, the second fiber concrete slab 2 ingredient be cement, water, fine aggregate, flyash, silicon Ash, granulated blast-furnace slag, metakaolin, water-reducing agent, nano-titanium dioxide, steel fibre.The match ratio of fiber concrete matrix is Cement: water: fine aggregate: flyash: silicon ash: granulated blast-furnace slag: metakaolin: water-reducing agent=1:(0.5-1.2): (0.6- 2.0): (1.0-2.5): (0.1-0.3): (0-0.3): (0.1-0.4): (0.01-0.025), nano-titanium dioxide volume are base The 3.0%~10% of the gross mass of body, the volume of steel fibre are the 1.0%-3.0% of the total volume of matrix.
The invention has the following advantages that
1) propagation of sound can effectively be obstructed
The densely covered small hole broad in the middle of opening of acoustical panel of the invention, allows incident acoustic wave to shake in the big cavity of mouth handle Swing, sound wave is collided with wooden partition and cavity floor, can effectively sound energy consumption, to have the function that sound-absorbing.
2) there is self-cleaning performance
Nano-titanium dioxide is mixed in acoustical panel of the invention, by the photocatalysis of nano-titanium dioxide, is decomposed mixed The dirt on solidifying soil surface, and attachment is easy to by rainwater and gasflow clean-up, therefore can guarantee the cleaning of concrete surface.Together When, nano-titanium dioxide can also promote the decomposition of the exhaust gas of the vehicle emissions such as nitrogen dioxide, carbon monoxide, to play net Change the effect of air.
3) easy for construction, simple structure
The connection of acoustical panel of the invention does not need directly to pass through the overhanging of concrete surface using traditional connection type Trapezoidal concrete block connected with trapezoidal groove, simple structure is easy for construction.
4) not easy to crack
It joined steel fibre in acoustical panel of the invention, the tension of concrete, the ability of cracking resistance can be effectively improved, Acoustical panel of the invention has good mechanical property compared to common acoustical panel.
Detailed description of the invention
In order to more clearly describe the present invention, here is that the present invention carries out simple Detailed description of the invention.
Fig. 1 is the top view of noise reduction plate unit.
Fig. 2 is A-A sectional view of noise reduction plate unit.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description.
As shown in Figs. 1-2, noise reduction plate unit includes the first fiber concrete slab 1, the second fiber concrete slab 2, the The overhanging trapezoidal concrete block 4 on trapezoidal groove 3, the second fiber concrete slab 2, bloop on one fiber concrete slab 1 5。
The ingredient of first fiber concrete slab 1 and the second fiber concrete slab 2 of the invention be cement, water, fine aggregate, Flyash, silicon ash, granulated blast-furnace slag, metakaolin, water-reducing agent, nano-titanium dioxide, steel fibre.Fiber concrete matrix Match ratio is cement: water: fine aggregate: flyash: silicon ash: granulated blast-furnace slag: metakaolin: water-reducing agent=1:0.601: 0.755:1.275:0.130:0.103:0.157:0.015, nano-titanium dioxide volume are the 5.39% of the gross mass of matrix, steel The volume of fiber is the 2.13% of the total volume of matrix.
Bloop 5 is the small hole broad in the middle of opening, and bloop 5 is by penetrating tubaeform on two pieces of fiber concrete slabs Hole docks to be formed, and bloop is uniformly distributed on acoustical panel.
Noise reduction plate unit of the invention passes through trapezoidal groove 3 by the first fiber concrete slab 1 and the second fiber concrete slab 2 It is spliced with trapezoidal concrete block 4, trapezoidal concrete block 4 is inserted tightly into trapezoidal groove 3.When acoustical panel unit spliced, First fiber concrete slab 1 deviates the groove of a longitudinal direction relative to the second fiber concrete slab 2 outward, and the groove of the longitudinal direction is made For the connection structure between other noise reduction plate units and the noise reduction plate unit.
