Description
Technical field
The utility model relates to field of environment protection；Particularly relate to noise reduction environmental protection equipment；It is specifically related to a kind of high ferro bridge nonmetal high-strength light acoustic barrier unit board.
Background technology
Now after High Speed Railway Trains successful operation, bring great convenience to people's trip, but the running noises of high ferro also to bring the biggest infringement, particularly high-speed rail bridge to cause to both sides resident especially pronounced.In view of the particularity of bridge structure, do not require nothing more than effective noise reduction, in addition it is also necessary to ensure the unlikely reduction of acoustical behavior of acoustic barrier unit board as far as possible.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of high ferro bridge nonmetal high-strength light acoustic barrier unit board, its acoustics, mechanics, physical property all reaches the requirement in the state-owned railroads technical standard (TB/T3122-2010 " railway sound barrier acoustics constructing technology requires and method of testing ") of high-speed rail bridge sound barrier.And can effectively prevent inner inlet, and then the absorbent treatment sound absorbing capabilities that makes moist declines.
For reaching above-mentioned purpose, the utility model adopts the technical scheme that:
A kind of high ferro bridge nonmetal high-strength light acoustic barrier unit board, in order to rearrange sound barrier, including:
Having a closed shell of internal cavities, the material of described closed shell is lightweight concrete, and it includes a upper head plate, a panel, a bottom plate and the backboard that head and the tail connect successively；Described internal cavities is filled with an absorbent treatment；
Described absorbent treatment includes the rock cotton board being positioned at panel side, is positioned at a grain plastic plate of backboard side, and the glass film between described rock cotton board and described panel；
Offering uniform multiple elongated holes on described panel, punching rate is 23-27%；Described elongated hole is bellmouth；Its range of taper 0.125 to 0.1429.
Further, the appearance and size of described cell board is long 1960 to 3960 millimeters, high 430 to 500 millimeters, thickness 120 to 140 millimeters.
Further, the thickness of described panel is 35 to 40 millimeters；The thickness of described backboard is 30 to 35 millimeters；The thickness of described upper head plate and bottom plate is 35 to 40 millimeters.
Further, the thickness of described rock cotton board 50 to 60 millimeters, the thickness of grain plastic plate is 10 to 25 millimeters, and the thickness of glass film is 0.1 to 0.2 millimeter.
Further, the middle level of described backboard and/or panel is embedded with 4 to 6 millimeters of bar-mat reinforcements of diameter.
Further, a length of 80 to 120 millimeters of each grid of described bar-mat reinforcement, width is 80 to 120 millimeters.
By taking technique scheme, suitably offer bellmouth at panel, Unit Weight can not only be reduced and reduce load, and the entrance of beneficially sound wave, make noise be absorbed greatly；The rainwater being additionally splashed in hole when running into rainy weather can be easy to outside tap hole, unlikely makes rainwater enter in acoustic barrier unit board housing, makes the sound-absorbing material in housing unlikely because making moist and sound absorbing capabilities declines.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clear, complete description.
In one embodiment, it is provided that a kind of nonmetal high-strength acoustic barrier unit board of high ferro bridge；As shown in Figures 1 and 2, including: having a closed shell of internal cavities, the material of this closed shell is lightweight concrete, it include successively head and the tail connect upper head plate 3, panel 1, bottom plate 4 and backboard 2；Internal cavities is filled with an absorbent treatment (not shown)；Absorbent treatment includes the rock cotton board being positioned at panel 1 side, is positioned at a grain plastic plate of backboard 2 side, and the glass film between rock cotton board and panel 1.
Appearance and size according to practice of construction situation cell board is chosen as: length 1960 to 3960 millimeters, highly 430 to 500 millimeters, thick 120 to 140 millimeters.
Wherein, the thickness of panel 1 is chosen as 35 to 40 millimeters.Offering uniform multiple elongated holes on panel 1, punching rate is 25%.As it is shown on figure 3, described elongated hole is bellmouth；Its range of taper 0.125 to 0.1429.The import external surface area sum total of bellmouth is about 35% to 40% with acoustic barrier unit board surface area ratio.Bellmouth beneficially train noise sound wave enters sound-absorbing material and is prone to be absorbed.Additionally at rainy day environment, rainwater is liable to flow out after being splashed into bellmouth, thus ensure that the unlikely water of cell board inner chamber, and in also ensuring that chamber, sound-absorbing material will not change performance because making moist.It addition, when manufacturing sound barrier, bellmouth is prone to the demoulding of panel mold；From the surrounding's cracking without making panel bore a hole.
The thickness of backboard 2 is chosen as 30 to 35 millimeters.The thickness of upper head plate 3 and bottom plate 4 is 35 to 40 millimeters.
It addition, upper head plate 3 and bottom plate 4 are respectively formed with the convex beam isometric with cell board, groove.Fasten so that stable between neighbouring two cell boards.On this basis, a sealing gasket also it is equipped with between neighbouring cell board.
Additionally, for ensureing intensity, the middle level of backboard 2 is embedded with 3 to 6 millimeters of bar-mat reinforcements of one layer of diameter.A length of 80 to 120 millimeters of each grid of this bar-mat reinforcement, width is 80 to 120 millimeters.Alternatively, same bar-mat reinforcement is also buried underground in the middle level of panel 1.
Finally, in absorbent treatment, the thickness of rock cotton board 50 to 60 millimeters, the thickness of grain plastic plate is 10 to 25 millimeters, and the thickness of glass film is 0.1 to 0.2 millimeter.
Support post is made up of H profile steel, and cell board can insert, by 5-6 block, the sound barrier unit that the H profile steel column of both sides is formed, and according to design requirement or the practice of construction requirement of sound barrier, then is formed a complete sound barrier by a series of unit.
Obviously, described embodiment is only a part of embodiment of the utility model rather than whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of the utility model protection.
