The invention discloses an expansion joint structure for a wagon balance, and belongs to the technical field of expansion joints for wagon balances, the expansion joint structure comprises two symmetrically mounted section steels, an expansion joint is reserved between the two section steels, and a flexible sealing assembly which is distributed along the length direction of the expansion joint and is used for sealing the lower layer of the expansion joint is arranged between the two section steels; a flexible sealing rubber strip used for sealing the upper layer of the expansion joint is arranged between the flexible sealing assembly and the expansion joint. A space defined by the flexible sealing rubber strip, the horizontal upper sealing layer and the upper convex lower sealing layer is filled with expansion sponge which expands when encountering water. The flexible sealing assembly and the flexible sealing rubber strip are sequentially arranged between the two pieces of profile steel from bottom to top, and the situation that the sealing effect is affected due to abrasion caused by repeated use is avoided through the multiple sealing layers; the space defined by the flexible sealing rubber strip, the horizontal upper sealing layer and the upper convex lower sealing layer is filled with the expansion sponge, the expansion sponge expands when encountering water to extrude the upper convex lower sealing layer, and the sealing effect of the upper convex lower sealing layer is better.
本发明公开了一种地磅用伸缩缝结构，属于地磅用伸缩缝技术领域，本发明包括两对称安装的型钢且两型钢间留有伸缩缝，两型钢之间设有沿伸缩缝的长度方向分布用于密封伸缩缝下层的柔性密封组件；柔性密封组件与伸缩缝之间设有用于密封伸缩缝上层的柔性密封胶条；柔性密封胶条、水平上密封层以及上凸型下密封层围成的空间内填充遇水膨胀的膨胀海绵。本发明在两型钢之间自下至上依次设有柔性密封组件以及柔性密封胶条，通过多层密封层避免多次使用导致磨损影响密封效果；通过在柔性密封胶条、水平上密封层以及上凸型下密封层围成的空间内填充膨胀海绵，膨胀海绵遇水膨胀挤压上凸型下密封层，使得上凸型下密封层密封效果更好。
