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 high ferro high-strength acoustic barrier unit board of bridge metal, including: there is a closing housing of internal cavities, as shown in Figures 2 to 4, including backboard 2, be formed with a upper groove, protruding a, low groove and a lower convexity on one；It is embedded at gusset 3 at least in described upper groove, is formed with on one first holding tank on holding tank and one second；Gusset 2 the most once being embedded in described low groove, are formed with one first time holding tank and one second time holding tank；Panel 1, has the outside upper groove with described protruding fastening and the outside low groove fastened with described lower convexity；
On first, holding tank and first time holding tank constitute one first holding tank；On second, holding tank and second time holding tank constitute one second holding tank；Cell board also includes: be installed on the sound insulationg board 5 of the first holding tank；It is installed on the sound-absorbing material layer 6 of the second holding tank.
Panel 1 also includes a front portion, and in conjunction with Fig. 1, described front portion offers the circular hole of uniform several diameters 4 to 6 millimeters, and punching rate is 28% to 32%.
It addition, the appearance and size of cell board is long 1960 to 3960 millimeters, high 430 to 500 millimeters, thickness 120 to 140 millimeters.The material of panel and backboard is the aluminium alloy plate of 1.5 to 2 millimeters thick.Upper gusset and a length of 30 to 50 millimeters of lower gusset.The thickness of sound insulationg board is 9 to 11 millimeters.The thickness of sound-absorbing material layer is 35 to 45 millimeters.The outside of sound-absorbing material has the glass film layer of cladding 0.1 millimeters thick.
Additionally, as shown in Figure 5, Figure 6, backboard 2 rolling has the longitudinally convex muscle of the arc of uniform arrangement, protruding to the outside of cell board.By special mould, aluminium alloy plate rolling is formed.This structure of backboard drastically increases the integral rigidity of aluminium alloy cell board, both having made high ferro train operation speed per hour at 350 kilometers to 380 kilometers, Pneumatic pressure produced by it acts on the deformation within it also will not be made on aluminium alloy acoustic barrier unit board to produce limit value.Vertical raised ribs is the most protruding, thus does not affect cavity volume size cell board within, upper and lower gusset, sound insulationg board, the layout of sound-absorbing material and lay in nor affecting on cavity.Further, the longitudinal rib formed by rolling is the bulk strength improving cell board on the premise of the weight of cell board does not change.
It should be noted that, the quantity of longitudinally convex muscle and layout are not limited to shown in figure, structure explanation the most for example in figure.In other embodiments, the quantity of longitudinally convex muscle and arranging is based on the concrete size of unit and specification chooses.
It has been observed that the panel of cell board and backboard fasten as flexibly connecting, upper gusset is contained in the upper end of backboard cavity, lower gusset is contained in the lower end of backboard cavity, sound panel and sound-absorbing material are contained between gusset and lower gusset, and sound panel is positioned at after sound-absorbing material, and panel is fastened on backboard.The cross section of panel is an inverted l shape, the perforation on the front of panel, makes sound wave enter in sound barrier from perforation and is predominantly absorbed a part.
It is provided with closed guard in panel both sides.Described backboard is a uncovered casing, and is respectively provided with a boss in the middle part of backboard bottom surface in the middle part of backboard upper surface, in order to upper gusset, lower gusset location and installation, the opening part at backboard is provided with bound edge, is provided with baffle plate in the both sides of backboard.The middle part of described upper gusset and lower gusset is provided with narrow wide two grooves that can place sound panel and sound-absorbing material, the narrow groove placing sound panel is located at gusset and the postmedian of lower gusset, the wide groove placing sound-absorbing material is located at gusset and the middle front part of lower gusset, is provided with flange in the two edges of upper gusset and lower gusset.
Can be inserted, by 5-6 block, the sound barrier unit that the H profile steel column of both sides is formed by the cell board of Fig. 1, according to the design requirement of sound barrier, a series of unit form a complete sound barrier.
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.
