Rubber of rubber track board of railway crossing

Abstract

The invention discloses a rubber layering of a rubber track board of a railway crossing. The rubber track board comprises a track board body and two recesses. The track board has outer sides corresponding to two rails and each forming a stepped portion. The two recesses are respectively formed in the stepped portions and each recess comprises a plurality of coupling holes formed therein. The rubber layering comprises a layering body inlayed correspondingly to the recess of the rubber track board, a plurality of fastening bars formed on an undersurface of the strip body, and a plurality of support bars respectively set inside the plurality of fastening bars. Each of the fastening bars is set to penetrate through each of the coupling holes to make the rubber layering and the recess of the rubber track board coupled to each other. Because each fastening bar has a bar strength reinforced by the support bar set therein, the problem that the rubber is apt to embrittle and fracture due to weathering effect in dismounting the fastening bar can be overcome.

Description

technical field [0001] The present invention relates to a rubber bead for a railway level crossing and its fixing rods, in particular to a rubber bead with a support rod inside each fixing rod. Background technique [0002] The existing rubber bead that fixes the rubber track slab of the railway level crossing, for example: Taiwan Patent No. I12012056 "Rubber bead for fixing the rubber track slab of the railway level crossing" invention patent, please refer to figure 1 , which discloses a rubber bead 93 comprising a plurality of fixing rods 94, whose function is to fix a rubber track 91 of a railway level crossing; the rubber track 91 is laid between two parallel steel rails of the railway level crossing; the The rubber track 91 includes a plate main body 911 and two grooves 92. The track main body 911 has a top surface 912, a bottom surface 913 and two stepped portions 914. At each outer side of the two parallel rails, the two grooves 92 are respectively arranged on each o...

Problems solved by technology

[0006] Each of the fixing rods 94 of the rubber bead 93 is a rubber material. When inserting into each of the joint holes 921 of the rubber track plate 91, the hardness of the rubber material is not enough, so that the construction personnel are not easy to concentrate. Hit the upper surface 932 of the rubber bead 93 with a mallet, so that the plurality of fixing rods 94 are slowly inserted into the corresponding plurality of coupling holes 921 one by one, thus making the installation process time-consuming.

[0007] In addition, because the rubber material is exposed to ultraviolet light for a long time outdoors, coupled with other weathering effects, the rubber material is easy to deteriorate and loses elasticity and is easy to be brittle and broken. When the rubber track plate 91 or the rubber bead 93 needs to be replaced , the plurality of fixing rods 94 are easy to break in the plurality of combining holes 921 during disassembly, thus increasing the construction time, so how to shorten the construction time and prevent the plurality of fixing rods 94 from breaking in the plurality of combining holes 921, the will be a topic for discussion
