In technique scheme, described outer tooth ring 1 is made up of two semicircle outer tooth rings or a plurality of circular arc type outer tooth ring.
In technique scheme, the external tooth profile of tooth of described outer tooth ring 1 section is an acute angle, and cross-section structure is trapezoidal; Extruding circle 2 is up big and down small taper shape, and the height of outer tooth ring 1 is greater than the height of extruding circle 2.
Level crossing paving connecting structure, it comprises sleeper 4, is positioned at the paving plate 5 on the sleeper 4, and nail hole 6 is arranged on the paving plate 5, it is characterized in that the described railway spike 7 that is positioned at nail hole 6 passes paving plate 5 and connects sleeper 4, the last square nut of described railway spike 7 is trapped extruding circle 2 is housed, and outside the extruding circle 2 outer tooth ring 1 is arranged.
In technique scheme, described outer tooth ring 1 is made up of two semicircle outer tooth rings or a plurality of circular arc type outer tooth ring.
1., expansion loop can embed the hole wall of rubber flooring, avoids the screw spike hole to lose efficacy, and solved the difficult problem that the inefficacy slab utilizes again the utlity model has following advantage:.2., the special-purpose railway spike that expands can guarantee rubber paved crosing Stability Analysis of Structures, makes rubber paving plate nail hole return to normal result of use, 3., level crossing paving connecting structure, realized being connected firmly between slab and sleeper.It has solved the big problem of rubber road junction maintenance effectively, thereby guarantees traffic safety and smooth and easy.4. the experiment proved that: the utility model can not only be stablized sub rail foundation, strengthens the road junction track structure; And direct benefit is considerable, and direct economic benefit can reach 60,000 yuan/10m according to one's analysis.
