The opposite sides of the canvas are fixedly connected with filling plates. The beam plate expansion joint filling structure has the advantages of being convenient to replace and having a sound insulation function, and solves the problems that in the using process of an existing beam plate expansion joint filling structure, an expansion joint is usually directly filled with foamed plastic or asphalt silk and hemp, a user cannot conveniently disassemble and replace the expansion joint in the later period due to the filling mode, and therefore the filling effect is affected, and the use cost is lowered. And due to the fact that the structure is single and does not have the sound insulation function, noise at the top of the beam plate cannot be effectively isolated, and the applicability of the beam plate expansion joint filling structure is reduced.
