Be fixed on column with backboard by I-steel, be evenly arranged prestressed high-strength reinforcing bar in panel and backboard, panel and backboard it
Between hollow space fill sound-absorbing rock wool, sound-absorbing rock wool be with three one-dimensional disorders connection reticular structure, panel have hole, back
Plate is entity, not apertured hole；Wherein the panel and backboard of top and bottom end are fixed on column by channel steel；Channel steel and I-steel
Both ends and it is intermediate be equipped with limit plate, be provided with bolt hole, spiral shell at the edge of a wing that channel steel and I-steel both ends are overlapped with the column edge of a wing
Bolt passes through bolt hole, and the part setting nut that is pierced by of bolt is fixed.
The advantages of the utility model: fabricated construction can make its construction is simple.Panel and backboard independent construction, make list
A member dead weight is small, is readily transported, loads and unloads simply.Panel and backboard poured by the Reactive Powder Concrete mixed with steel fibre and
At, have the characteristics that fold resistance is good and intensity is high, improve the cracking resistance of cell board, improve durability and service life,
The tensile property of high tensile steel wire can be made full use of, and mold is recycled simultaneously etc..Apply prestressing force, coagulation can be effectively controlled
The development of soil cracking seam, while also further improving the crack resistance of panel and backboard.The highly resistance of reactive powder mixed mud itself is rolled over
Property and prestressed application, so that cell board is under the premise of proof strength and non-unstability, maximumlly reduction unit plate section
Thickness mitigates member dead weight.

Specific embodiment
Embodiment:
The concrete operations of the utility model are described below by specific example, the operation of this example is only used for this
The further explanation of utility model, but be not the limitation to scope of protection of the utility model, and those skilled in the art are made
The content that non-intrinsically safe changes also belongs to the protection scope of the utility model.
In conjunction with Fig. 1 to Figure 10.
As shown, sound barrier includes the column of Along Railway setting, column is fixed on armored concrete bottom beam.
Acoustic barrier unit board panel and backboard mixed with the Reactive Powder Concrete of a certain amount of steel fibre in punching block by pouring
It forms, Reactive Powder Concrete uniformly smears one layer of release agent before pouring first in punching block, then that both ends are screwed
High tensile steel wire is each passed through panel and the rigid mould both ends of backboard reserved 11 and 8 holes, both ends partial threads are exposed at respectively
On the outside of punching block, then nut is tightened to by measuring spanner for force moment and calculates control stress for prestressing value, to realize high tensile steel wire
Tensioning.Tensioned at one end, which can be used, in tensioning can also be used both ends tensioning.Concreting is carried out after high tensile steel wire tensioning is complete and is vibrated
It is closely knit, finally surface is smoothed out, after the completion of maintenance, put and opens, cut off extra steel wire, mold is reusable, I-steel
With channel steel according to required specifications and models outsourcing.
After the completion of panel 1 conserves, the side of panel 1 is pasted to the black felt-cloth of homalographic, to prevent rainwater or foreign matter along hole
Hole enters in cell board.The both ends of the top channel steel 4 and following I-steel 5 and intermediate position are respectively welded one piece perpendicular to the edge of a wing
Small steel plate as limit plate 8,8 two sides of limit plate reserve the thickness of panel 1 and backboard 2,6 notches are formed, so as to 1 He of panel
Backboard 2 passes through, and generates position-limiting action.
Prefabricated acoustic barrier unit board panel 1(has been pasted into black felt-cloth) and backboard 2 and sound-absorbing rock wool 7, channel steel 4,
I-steel 5 transports to construction site and carries out assembly.The channel steel 4 that will be close to armored concrete bottom beam first is fixed on by bolt 9
Between column 3, central post 3 is that H profile steel, channel steel 4 and I-steel 5 and column 3 are orthogonal, at vertical and intersection node
The edge of a wing of channel steel 4 or I-steel 5 is connected and fixed with 3 edge of a wing binding face of column using bolt 9；Then backboard 2 is inserted into outside channel steel 4
In the notch of side, then panel 1 is inserted into the notch of the inside of channel steel 4；Finally, sound-absorbing rock wool 7 is filled into backboard 2 and panel
In hollow structure between 1.Already fixed panel 1 and backboard 2 are fixed again with the notch of 5 side of I-steel,
And I-steel 5 and the bolt 9 of column 3 are attached fixation, it successively carries out above-mentioned steps and repeats assembly, used when top
The notch of channel steel 4 carries out last assembly to panel 1 and backboard 2, and is connected and fixed with column 3 by bolt 9, while also reaching envelope
The purpose on top.
Panel and backboard described in the utility model are poured by Reactive Powder Concrete, and anti-folding with higher is strong
Degree, therefore under the premise of proof strength, it compared with normal concrete acoustic barrier unit board, can reduce section thickness, mitigate
Self weight.Due to being applied with prestressing force to panel and bottom plate, so the rigidity of cell board, intensity, cracking resistance and durability are into one
Step is improved, and under the premise of not unstability, section thickness can reduce again, makes cell board from lightest.Pacified using pin-connected panel
Dress, can simplify construction to the maximum extent, carry out convenience for large-scale production and conveyer belt.
