The invention belongs to the technical field of traffic environmental protection facilities and relates to a protective anti-throwing screen. The screen comprises a plurality of fixing seats; the multiple fixing seats are arranged at equal intervals; embedded bolts penetrate through the fixing seats; the ends, located outside the fixing seats, of the embedded bolts are fixedly connected with a bottom plate through nuts; H-shaped steel stand columns are vertically fixed to the bottom plate; a plurality of protective screen bodies are arranged between every two adjacent H-shaped steel stand columns; two sides of each protective screen body are inserted into the notches of the H-shaped steel stand columns respectively and fixed through fixing bolts; an upper connecting groove and a lower connecting groove are formed in the two ends of each protective screen body respectively; the adjacent protective screen bodies are connected in a clamped mode through the upper connecting grooves and thelower connecting grooves and are fixed into an integrated structure through rivets; and a plurality of rows of ventilation devices are arranged on each protective screen body in the length directionof the protective screen body. Wind resistance can be weakened; the whole screen body is designed in a unitization mode; height can be continuously increased in a unitization mode; the protective anti-throwing screen is composed of a plurality of units; the installation of the protective anti-throwing screen is reasonable and convenient; construction speed is high; and the screen is worthy of popularization.
Description
technical field [0001] The invention relates to the technical field of traffic environmental protection facilities, in particular to a protective anti-throwing screen. Background technique [0002] With the rapid development of the city, the urban traffic is becoming more and more complicated, and the noise pollution brought to the city is becoming more and more serious, and the impact of road traffic noise is increasing. Pedestrians bring safety hazards. In order to reduce noise pollution and risks caused by high-altitude parabolic objects, anti-throw screens are generally built on both sides of the road. Anti-throw screens are mainly composed of foundations, columns and anti-throw screen panels. The foundation is anti-throw screens The main load-bearing structure of the slab, it can be designed separately or on the road ancillary facilities when designing the road; the column is the main force-bearing component of the sound barrier, and it can be connected with the sound b...
