The strip rectangle unfilled corner of docking, edge is arranged to curved inside the strip rectangle unfilled corner inside and outside the structural framing
Head sealing sheet；
--- structural framing upper and lower ends setting top cover and bottom plate, the top cover and bottom plate have card slot, for
It is fixed inside and outside the structural framing.
A kind of novel sound barrier assembled by above-mentioned sound absorption cell board, technical solution are as follows: between the adjacent structural framing
It is that I-shaped support keel connects by section, the left and right sides of the support keel is formed for fixing the structural framing
Groove body, the slot arm of the groove body is inserted into the strip rectangle unfilled corner, and is engaged by the head sealing sheet, the support keel with
The structural framing, top cover, the contact site of bottom plate and the top cover, bottom plate and the structural framing contact site use
Rivet is fixed.
A kind of novel acoustic barrier unit board provided by the utility model and its novel sound barrier assembled with it is existing
Technology is compared, and is had the advantage that first, having structural strength height, capable of accomplishing full frequency band sqouynd absorption lowering noise, especially anti-low frequency
Noise generate pulsed air pressure loading impact, rubber material weather resistance is strong, be not afraid of wind and weather, it is heat-resisting, resistance to it is molten freeze,
It prevents fires and does not pollute the environment；Second, the novel sound barrier assembled by the open cell type rubber acoustic board, production is easy, peace
Fill quick, short construction period, long service life, in high-speed railway two sides in use, its sqouynd absorption lowering noise has special effect.
Detailed description of the invention
Fig. 1 is a kind of cross-sectional structure schematic top plan view of novel acoustic barrier unit board provided by the utility model；
Fig. 2 is the socket joint attachment structure schematic diagram of the cell board；
Fig. 3 is the vertical section structure schematic diagram for the novel sound barrier that the cell board is assembled into.
Specific embodiment
Below to a kind of novel acoustic barrier unit board provided by the utility model and its novel sound barrier assembled
Structure is described in further detail.
Novel acoustic barrier unit board as shown in Figure 1 mainly by structural framing 1, it is inside and outside to be respectively arranged at structural framing 1
The punching panel 2 and beading backboard of two sides, the acoustic board 4 being set between punching panel 2 and beading backboard 3 are constituted；Its
In, above-mentioned acoustic board 4 is open cell type rubber acoustic board structure.
In constituting a kind of above-mentioned structure of novel acoustic barrier unit board,
--- above-mentioned punching panel 2 and beading backboard 3 are made of aluminium alloy, and the sound absorption bore dia of punching panel 2 exists
For 25mm between 45mm, punching density is 80/square metre to 120/square metre, and porosity is 35% to 55%, has quality
Light, the processing is simple, absorbs the good feature of sound wave effect；
--- as shown in Fig. 2, above structure frame 1 is made of aluminium alloy, structure in order to improve the integral strength of cell board
The left and right sides of frame 1 has the strip rectangle unfilled corner 5 docked convenient for cell board socket joint, edge inside and outside structural framing 1
It is arranged to the 5 curved head sealing sheet 6 in inside of strip rectangle unfilled corner, that is, is convenient for cell board assembly and connection, is easy to construct；
--- 1 upper and lower ends of above structure frame are arranged top cover 7 and bottom plate 8, top cover 7 and bottom plate 8 have card slot (71,
