Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of nonmetal unit board for sound barrier that the present embodiment provides, it comprises the housing that has cavity, described housing comprise be positioned at noise produce side the acoustical board 1 being provided with sound penetrating hole 7, be positioned at the sound barrier 2 of this acoustical board 1 opposite side and connect epipleural 3 and the lower side panel 4 of described acoustical board 1 and sound barrier 2, it also comprises the stiffener 8 of the described acoustical board 1 of connection between epipleural 3 and lower side panel 4 and sound barrier 2.For increasing the bulk strength of housing, stiffener 8 is at least two.
The thickness of described acoustical board 1, sound barrier 2, stiffener 8 is 5 ~ 80mm, for weight reduction, preferred thickness is 5 ~ 40mm, material can require to select according to practice of construction, common are cement, lightweight aggregate etc., for further weight reduction, the thickness of stiffener 8 and sound barrier 2 can be less than the thickness of acoustical board 1.
When arranging two stiffeners 8, as shown in Figure 1, stiffener 8 setting parallel to each other, stiffener 8 and epipleural 3 and lower side panel 4 can parallel also can be vertical.Alternatively, as shown in Figure 3, the orthogonal setting of stiffener 8, vertical mode is as shown in A and B in figure.
