Abstract
The utility model discloses a noise-proof screen which is provided with an anti-falling protective device and is used for an overhead frame and both sides of a road. The utility model is mainly composed of an upright post, a socket, the noise-proof screen, a pressing plate and a decorative plate, wherein, the upright post arranged on the socket is arranged in the back of the noise-proof screen. The upright post is clamped through the pressing plate, and the outside is coated with the decoration plate. The utility model is characterized in that the anti-falling protective device is arranged on the noise-proof screen and the upright post. The utility model has the advantages of artful design and reasonable structure. The happen of a road traffic accident can be effectively avoided when the noise-proof screen is struck and fallen on a roadway. Thus the noise-proof screen is provided with popularization value.
Description
The utility model relates to a kind of sound insulation protective device, particularly relates to a kind of anti-noise screen that has anti-fall protective device overhead, the road both sides that is used for.
On elevated road, because the travel speed of vehicle is very fast, the time one is long, and driver's vision very easily produces fatigue.And the acoustic screen of employing laminated glass not only helps passenger's appreciation landscape on the way, also can extenuate the degree of driver's visual fatigue.So at present, the anti-noise screen that uses in the elevated road both sides, what the acoustic screen that wherein has adopted is the interlayer implosion guard.But after this acoustic screen is clashed into, very easily fall within the road surface, thus, can bring adverse influence to road traffic.
The purpose of this utility model provides a kind of, can effectively overcome above-mentioned defective, has the anti-noise screen of anti-fall protective device.
The technical solution of the utility model is; a kind of anti-noise screen; mainly form by column, base, acoustic screen, pressing plate and decorative panel; after inserting acoustic screen before the column on the base; clamp by pressing plate; external packing plaque again, it is characterized in that: acoustic screen and column are provided with an anti-fall protective device.
Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed, and is rational in infrastructure, can avoid effectively being clashed into when acoustic screen, fall within the road surface after, cause the generation of road traffic accident, therefore, this anti-noise screen tool promotional value.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the local structure for amplifying schematic diagram of the anti-fall protective device of the utility model.
Among the figure, two heel posts 10 of this anti-noise screen and base 20 adopt rigid material to be made into integration, and respectively are provided with four nuts 21 on two wing bases 20, before the column 10 perpendicular put acoustic screen 30 after, use pressing plate 40 with its clamping again, outside pressing plate 40, fastening by rivet at last with decorative panel 50.Acoustic screen 30 is provided with an anti-fall protective device 60 with column 10.Anti-fall protective device 60 is two to have the connector 61 in two holes; wherein a borehole jack of a connection piece 61 has chain 62; inserting bolt 63 in another hole; after being encased inside pressing plate 67 and rubber washer 68 again; pass acoustic screen and opposite side be lined with rubber washer 68 and pressing plate 67 to change shape nut 64 fastening; the other end of chain 62 is placed in the hole of another connector 61, and bolt 65 passes another Kong Zhonghou of this connector 61, is threaded onto attack in threaded hole 66 corresponding with it on the column 10.Wherein, acoustic screen 30 is by the implosion guard of two-layer six millimeters thick, and the centre sandwiches the PVB film that du pont company produces and constitutes, and during installation, only needs pre-buried screw with the crashproof wall of cement of nut on this anti-noise screen base and overhead, road both sides to screw and gets final product.
