Abstract
The utility model relates to a road surface supporting facility especially relates to a novel sound barrier, including the cell board with fixed the fixing base of cell board, the fixing base is equipped with the block the last passageway and the lower passageway of cell board, the inner wall of going up passageway and lower passageway is equipped with the movable block, the movable block is followed go up passageway and the inside and outside springing of inner wall of passageway down, be equipped with the block on the cell board the recess of movable block, during the installation sound barrier, insert earlier the passageway with the cell board, the cell board extrudees the wall that enters with the movable block, during recess on the movable block meets the cell board, pop out again, the block is in the recess, then with under the cell board reinsertion in the passageway, equally, when the movable block meets the recess again, just, can pop out the block in the recess, the effect of fixed cell board has just so been played, the staff mounting screws of being convenient for, the step of installation has been simplified, time saving and labor saving, and improving mounting efficiency.
Description
Technical field
This utility model relates to a kind of road surface auxiliary facility, particularly relates to a kind of novel sound barrier.
Background technology
When high-speed railway, road vehicle operation or equipment run, a large amount of noise can be produced, interfere with roadside and neighbouring resident, school and Office Area. Currently mainly carry out the propagation of blocking noise by arranging sound barrier, thus reaching to prevent the purpose of noise pollution.
Traditional acoustic barrier unit board, it is made up of acoustic board, sound-absorbing material and sound insulationg board, in the cavity constituted between acoustic board and sound insulationg board, sound-absorbing material is set, sound wave enters sound-absorbing material by the sound-absorbing hole on acoustic board, sound wave can go deep into material internal along the space of sound-absorbing material, with material generation rubbing action, acoustic energy is converted into heat energy, after the sound wave of traverse sound-absorbing material strikes sound insulationg board surface, it is reflected back again sound-absorbing material, rubbing action occurs again with material, moves in circles, gradually noise is cleared up, reach the effect of sound-insulation noise.
When sound barrier is installed, acoustic barrier unit board is fixed on the fixed support of both sides of highway, it is common to use screw is fixed. Owing to cell board volume is bigger, it is necessary to a people is by the position alignment between cell board and fixed support, and a people is screwed, when so operating, relatively time-consuming effort, and inefficiency.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of novel sound barrier so that it is have more the value in industry.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of novel sound barrier, convenient and swift during installation, time saving and energy saving, improves installation effectiveness.
The novel sound barrier of one that the utility model proposes, fixing seat including cell board and fixing described cell board, described fixing seat is provided with the upper channel and lower channel that engage described cell board, the inwall of described upper channel and lower channel is provided with movable block, described movable block is along springing inside and outside the inwall of described upper channel and lower channel, and described cell board is provided with the groove engaging described movable block.
Further, the bottom of described lower channel is provided with inclined-plane, and the lower on described inclined-plane is provided with osculum.
Further, it is provided with spring between the inwall of described movable block and described lower channel, lower channel.
Further, described fixing seat is provided with noise transducer.
Further, it is mixed with reinforced plastic glass fibre muscle in described cell board.
By such scheme, this utility model at least has the advantage that this utility model is provided with movable block in the upper channel and lower channel of fixing seat, during installation, cell board is first inserted upper channel, movable block is squeezed into inwall by cell board, when movable block runs into the groove on cell board, eject again, it is fastened in groove, then cell board is inserted in lower channel, same, when movable block runs into groove again, will be combined in groove by ejecting card, thus serve the effect of fixed cell plate, it is easy to staff and screw is installed, simplify the step of installation, time saving and energy saving, improve installation effectiveness.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing describe in detail as after.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail. Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
Referring to Fig. 1, the novel sound barrier of one of this utility model one preferred embodiment, fixing seat 2 including cell board 1 and fixed cell plate 1, fixing seat 2 is provided with upper channel 3 and the lower channel 4 of engaging unit plate 1, the inwall of upper channel 3 and lower channel 4 is provided with movable block 5, movable block 5 and lower channel 4, lower channel 4 inwall between be provided with spring, therefore can along springing inside and outside the inwall of upper channel 3 and lower channel 4, cell board 1 is provided with the groove 6 of engaging movable block 5. The bottom of lower channel 4 is provided with inclined-plane 7, and the lower on inclined-plane 7 is provided with osculum 8. Fixing seat 2 is provided with noise transducer. Reinforced plastic glass fibre muscle it is mixed with in cell board 1.
This utility model is provided with movable block 5 in the upper channel 3 and lower channel 4 of fixing seat 2, during installation, cell board 1 first inserts upper channel 3, movable block 5 is squeezed into inwall by cell board 1, when movable block 5 runs into the groove 6 on cell board 1, eject again, it is fastened in groove 6, reserved certain space in upper channel 3, cell board 1 can be continued up insertion, lower channel 4 is inserted in the lower end facilitating cell board 1, when cell board 1 inserts lower channel 4, same, when movable block 5 runs into groove 6 again, will be combined in groove 6 by ejecting card, thus serve the effect of fixed cell plate 1, it is easy to staff and screw is installed, simplify the step of installation, time saving and energy saving, improve installation effectiveness, the bottom of lower channel 4 is provided with inclined-plane 7 and osculum 8, in the rainy day, hydrops just along inclined-plane 7, can be discharged from osculum 8, it is to avoid the rainwater corrosion to cell board 1, fixing seat 2 is additionally provided with sensor noise, it is simple to the noise level of monitoring highway, in cell board 1 after hybrid glass steel fibre muscle, greatly strengthen its intensity, extend service life.
The above is only preferred implementation of the present utility model; it is not limited to this utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model know-why; can also making some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
