[0035] Embodiment 1:

[0036] As Figures 1 to 7 shown, this embodiment proposes a road closure device for bridge construction, including a baffle 1, a support diagonal rod 2, a fluorescent cushion layer 3, a retroreflective covering layer 4, a drag reduction air hole 5, an L-shaped steel foot support 6, a mounting hole 7, and a reinforcing rib 8 arranged inside the rear side frame of the baffle 1.

[0037] Among them, the baffle 1 is rectangular, with dimensions of 1.2m × 2.2m. A square frame is used to reinforce the baffle 1 at the rear side, and a reinforcing rib 8 is arranged inside the frame. The two ends of the reinforcing rib 8 are respectively fixedly connected to the middle positions on both sides inside the frame. A number of evenly distributed drag reduction air holes 5 are opened on the front side of the baffle 1. The front end of the drag reduction air hole 5 is low and the rear end is high, with an overall inclination of 45°. The drag of the baffle 1 is slightly reduced through the drag reduction air holes 5 to increase its wind resistance.

[0038] L-shaped steel foot supports 6 with an L-shaped cross-section are arranged on both sides of the lower side at the rear end of the baffle 1. Mounting holes 7 are opened at the front and rear of the lower end inside the L-shaped steel foot support 6, facilitating the fixation of the L-shaped steel foot support 6 to the ground through bolts. The L-shaped steel foot support 6 is fixedly connected to both sides of the lower end at the rear side of the baffle 1 through bolts, and support diagonal rods 2 are arranged on both sides between the L-shaped steel foot support 6 and the baffle 1. One end of the support diagonal rod 2 is connected to the side wall at the lower side and slightly below the middle inside the rear side frame of the baffle 1 through a bolt, and the other end of the support diagonal rod 2 is connected to a position slightly behind the side wall close to one side at the rear inside the L-shaped steel foot support 6 through a bolt to support and fix the baffle 1.

[0039] Fluorescent cushion layers 3 are arranged on both the upper and lower sides of the front side of the baffle 1, and retroreflective covering layers 4 are arranged on the front sides of the fluorescent cushion layers 3. The retroreflective covering layer 4 includes a base layer 401 at the rearmost side, which is used as a connection base with a polyethylene material. An adhesive layer 402 is arranged on the front side of the base layer 401 for pasting on the base layer 401. A silver-plated reflective layer 403 is arranged on the front side of the adhesive layer 402. The front side of the reflective layer 403 is composed of a number of evenly distributed microprisms spliced together. The microprisms are obtained by cutting a triangular pyramid with a bottom side length of 0.5mm long triangle. The cutting schematic is Figure 6 shown. After cutting, the microprisms are arranged closely, reducing the reflection area occupied by the gaps and enhancing the reflection effect.

[0040] AsFigure 7 The schematic diagram of light reflection shown, where the light can finally be reflected from the light parallel to the direction of entering the prism for the driver to see. Since current vehicles are designed to prevent glare and the irradiation angle of the vehicle's headlights is set a bit lower, fluorescent cushion layers 3 and retroreflective covering layers 4 are provided both above and below the front side of the baffle 1. In this way, when the vehicle is relatively far away, the upper part can be seen; when it is relatively close, the lower part can be seen; or both can be seen, increasing the driver's judgment time. The fluorescent cushion layer 3 is made of a fluorescent agent composite film and can emit light at the edge of the retroreflective covering layer 4 after absorbing light, enhancing recognition.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
