SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving the road bridge changeover portion and all can produce very big noise and lack the moulding structure of its internal support, easily take place the technical problem of serious deformation in long-time use, provide a road bridge changeover portion roadbed structure.
For realizing the above-mentioned purpose, the utility model provides a following technical scheme, a road bridge changeover portion roadbed structure, including cement roadbed and compression fittings, the inside fixed compression fittings that is provided with of cement roadbed, compression fittings includes i-shaped frame, rubber layer, moulding steel wire, spliced pole and fixed block, the inside fixed i-shaped frame that is provided with of cement roadbed, the fixed rubber layer that is provided with in i-shaped frame top, the fixed moulding steel wire that is provided with in rubber layer inside, all there is the spliced pole through bolt fixed mounting in the i-shaped frame left and right sides, the fixed block that is provided with in i-shaped frame inner wall top.
Furthermore, the cross section of the rubber layer is in an arch shape, and the upper surface of the rubber layer is provided with sawtooth-shaped anti-skid grains.
Furthermore, the connecting columns are uniformly arranged on the I-shaped frame at equal intervals.
Furthermore, the lower end of the fixing block is of a protruding structure, and the fixing block is tightly attached to the cement roadbed.
Furthermore, the shaping steel wires are uniformly arranged in a latticed manner in the rubber layer.
Has the advantages that:
1. this kind of road bridge changeover portion roadbed structure can reduce the vehicle through the vibrations energy that produces, can effectual reduction vehicle through the in-process to the impact force of road bridge changeover portion for the stability that the vehicle passed through is stronger, has improved this kind of road bridge changeover portion roadbed structure's bulk strength greatly, prevents that the vehicle from overweight from causing the condition of harm to the road bridge changeover portion.
2. Secondly, this kind of road bridge changeover portion roadbed structure can moulding support has played the effect of reinforcing the rubber layer, prevents that the vehicle from receiving the serious condition of warping of pressure in advancing, increases holistic life to avoid current rubber shock attenuation to lack and support moulding structure to its inside, lead to the condition that easily takes place serious deformation in long-time use.

Fig. 2 is an overall sectional view of the present invention.
Fig. 3 is an enlarged schematic view of the point a in fig. 1 according to the present invention.
In FIGS. 1-3: the concrete roadbed comprises a cement roadbed 1, a pressure-resistant device 2, an I-shaped frame 201, a rubber layer 202, a shaping steel wire 203, a connecting column 204 and a fixing block 205.
Detailed Description
Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b):
please refer to fig. 1-3;
the roadbed structure of the road and bridge transition section provided by the embodiment comprises a cement roadbed 1 and a compression-resistant device 2, wherein the compression-resistant device 2 is fixedly arranged in the cement roadbed 1;
the compression-resistant device 2 comprises an I-shaped frame 201, a rubber layer 202, a shaping steel wire 203, a connecting column 204 and a fixing block 205, the I-shaped frame 201 is fixedly arranged inside the cement roadbed 1, the rubber layer 202 is fixedly arranged at the top end of the I-shaped frame 201, the shaping steel wire 203 is fixedly arranged inside the rubber layer 202, the connecting column 204 is fixedly arranged on the left side and the right side of the I-shaped frame 201 through bolts, and the fixing block 205 is fixedly arranged at the top end of the inner.
Further, the rubber layer 202 cross-section is the arch form, and the rubber layer 202 upper surface is equipped with the anti-skidding line that is the cockscomb structure, and the rubber layer 202 that is the arch form through the cross-section can improve this kind of road bridge changeover portion roadbed structure's bulk strength greatly, prevents that the vehicle from overweight from causing the condition of harm to the road bridge changeover portion.
Furthermore, the connecting columns 204 are uniformly arranged on the I-shaped frame 201 at equal intervals, and the connecting columns 204 uniformly arranged on the I-shaped frame 201 at equal intervals can reduce the vibration energy generated by the passing of the vehicle, so that the impact force of the passing of the vehicle on the bridge transition section can be effectively reduced.
Further, the lower extreme of fixed block 205 is the protrusion structure, and fixed block 205 and cement roadbed 1 closely laminate, can strengthen the closely laminating with cement roadbed 1 through setting up of fixed block 205, is difficult for causing the damage to the road surface.
