The butterfly microporous plate is made of steel or aluminum, and can also be a bending component made of polymer composite material, and the plate surface is provided with micropores; the main wind reducing device can reduce the wind from big wind to small wind and the wind from small wind to no wind and reduce the high-speed wind to low-speed wind by the interaction of different bent side surfaces.

The connection angle sign indicating number is the right angle sign indicating number, for steel or aluminium system, plays the effect of connecting butterfly micropore board and interior knot orifice plate.

The rubber tube is in a P-shaped shape, is made of ethylene propylene diene monomer, is arranged at the end parts of two side surfaces of the anti-throwing screen unit plate, is arranged between the anti-throwing screen unit plate and the steel upright wing plate, and plays roles in buffering and damping.

The working principle of the screen-throwing prevention unit board is as follows:

the anti-throwing screen is of a light-tight and air-permeable structure, when airflow of aerodynamic pressure in the line passes through the unit plate, the airflow firstly passes through a large pore plate on the surface, the pore plate has a certain noise reduction function, the passing high-speed airflow reaches the butterfly-shaped micropore plate and passes through the special wind reduction structure of the butterfly-shaped plate, the wind speed is effectively reduced, and finally, the low-speed wind flows out of the anti-throwing screen through the pore plate.

In the process, the screen-throwing prevention unit plate has the functions of reducing noise, reducing wind, ventilating, dispelling wind and resisting aerodynamic impact, and the noise is effectively reduced and the wind speed is effectively reduced under the action of the pore plate and the micropore plate.

The anti-throwing screen cell plate is simple in construction and convenient to assemble, can be installed by inserting the steel stand column, and has an anti-throwing function, anti-dazzle, anti-falling, light weight and low cost.

Detailed Description

A section of protective anti-throwing screen is built on a bridge in a certain project and consists of steel upright posts, anti-throwing screen unit plates, post top caps and connecting bolts.

The basis is the crashproof wall that reserves when road or bridge design, and the steel stand is installed on the embedded anchor or the bar planting crab-bolt on basis. The anti-screen-throwing unit plates are inserted into the grooves of the two adjacent steel stand columns, and the unit plates are overlapped up and down to form an anti-screen-throwing plate with a certain height; the column top cap is mounted on the top of the steel column by using a connecting bolt.

The steel stand is hot rolling H shaped steel, and the specification adopts H175x175x7.5x11, and height 1.5 meters, interval 2 meters are arranged, as bearing structure and lay and prevent throwing the screen unit board.

The top cap of the column is a C-shaped bent plate of a 0.8mm galvanized plate, is matched with a steel stand column for use, and is fixed by using self-tapping of M5.5x35, so that the dropping of the screen-throwing prevention unit plate and the theft prevention are prevented.
