[0029] Reference Figure 1 As shown, the utility model provides a technical solution: an elevated bridge widening mechanism, comprising a bridge plate 1, the upper surface of the bridge plate 1 is paved with a paving layer 2, and the paving layer 2 is a concrete layer.

[0030] The following is a detailed description of its overall specific settings and functions.

[0031] Reference Figure 1-Figure 3As shown, in this embodiment: a number of partitions 5 are evenly installed on the upper surface of the two bridge plates 1, and the partitions 5 are made of metal. A filling layer 3 is arranged between the partition 5, the pavement layer 2 and the bridge plate 1, and the filling layer 3 is a concrete layer. Paving the filling layer 3 into a strip structure not only avoids the cracking of the filling layer 3, but also increases the friction of the vehicle driving between the assembled bridge plates 1, avoids the slippery road in rainy days, and the occurrence of vehicles slipping on the viaduct, and improves the use effect of widening the viaduct to a certain extent. The lower surface of the partition 5 is fixedly installed with a convex strip 8, and the upper surface of the bridge plate 1 is provided with a mounting groove 7, the size of the mounting groove 7 is compatible with the size of the convex strip 8, and the cross-section of the mounting groove 7 is an isosceles trapezoid. By providing the convex strip 8 and the mounting groove 7 of the isosceles trapezoidal structure, the stability of the partition 5 installed on the bridge plate 1 is improved.

[0032] A plurality of reserved holes 9 are evenly provided on the surface of the partition 5. Part of the concrete material will flow into the inner side of the reserved holes 9, thereby improving the strength of the connection between the filling layer 3 and the partition 5. A reserved groove 6 is provided on the side wall of the paving layer 2, and the cross section of the reserved groove 6 is formed by splicing a circle and a rectangle. By providing the reserved groove 6 provided on the side wall of the paving layer 2 and filling the inner side of the reserved groove 6 with concrete, the gripping strength of the connection between the filling layer 3 and the paving layer 2 can be improved.

[0033] Reference Figure 4-Figure 5 As shown, specifically, the upper surface of the filling layer 3 is paved with an anti-skid mat 4, and a plurality of anti-skid grooves 12 are evenly formed on the upper surface of the anti-skid mat 4. The anti-skid mat 4 can increase the friction force used at the joint above the bridge plate 1, avoiding the phenomenon of slippery roads on rainy days. By providing the anti-skid grooves 12, the friction force of vehicles traveling on the bridge plate 1 is further increased.

[0034] A plurality of cone rods 10 are evenly fixedly connected to the lower surface of the anti-skid mat 4. The cone rods 10 are inserted into the interior of the unseasoned filling layer 3, which facilitates the installation of the anti-skid mat 4. The side wall of the cone rod 10 is provided with a filling hole 11. Part of the concrete of the filling layer 3 will flow into the inner side of the filling hole 11, which improves the use strength of the cone rod 10 inserted into the filling layer 3.

[0035] Working principle: after the two bridge panels 1 are initially widened and connected, first slide the convex strip 8 to the inner side of the installation groove 7, and install the partition strip on the upper surface of the bridge panel 1. By setting the convex strip 8 and the installation groove 7 of the isosceles trapezoidal structure, the stability of the partition 5 installed on the bridge panel 1 is improved. At this time, concrete can be filled between the partition 5, the bridge panel 1 and the pavement layer 2. The concrete material will flow into the partition 5, the bridge panel 1 and the pavement layer 2. The filling layer 3 after paving will form a strip structure, thereby avoiding the cracking of the filling layer 3 after paving. By setting a reserved groove 6 opened on the side wall of the pavement layer 2, the concrete is filled in the inner side of the reserved groove 6, which can improve the grip of the filling layer 3 and the pavement layer 2 for docking, and improve the use strength of the widening mechanism. Part of the concrete material will flow into the inner side of the reserved hole 9, which improves the strength of the connection between the filling layer 3 and the partition 5. The wind After drying, a portion of the partition 5 will protrude, which can increase the stability of vehicles traveling above the spliced ​​bridge slab 1, and avoid the slippery road on the viaduct after rainy days. The cone rod 10 is inserted into the interior of the undried filling layer 3, and part of the concrete of the filling layer 3 will flow into the inner side of the filling hole 11, thereby improving the use strength of the cone rod 10 inserted into the filling layer 3. After the concrete is air-dried, the anti-skid pad 4 can increase the friction force used at the joint above the bridge slab 1, and avoid the slippery road of the viaduct on rainy days. By setting the anti-skid groove 12, the friction force of vehicles traveling on the bridge slab 1 is further increased. By setting the above-mentioned structure, the filling layer 3 is paved into a strip structure, which not only avoids the cracking of the filling layer 3, but also increases the friction force of vehicles traveling between the assembled bridge slabs 1, avoiding the slippery road in rainy days and the occurrence of vehicles slipping on the viaduct, thereby improving the use effect of widening the viaduct to a certain extent.
