Fabricated tension-free telescopic device
The invention provides an assembly type tension-free expansion device, and relates to the technical field of bridges, the assembly type tension-free expansion device is used for being arranged at an expansion joint between two adjacent beam bodies, the assembly type tension-free expansion device comprises a first anchoring block, a second anchoring block and an elastic body, and the first anchoring block and the second anchoring block are used for being arranged on the two adjacent beam bodies correspondingly; the material of the elastic body comprises a polyurethane composite material, the elastic body is arranged between the first anchoring block and the second anchoring block and is in a compressed state, and the elastic body is used for covering the expansion joint. No matter whether the opening amount of the expansion joint is increased or decreased, the elastic body is in a tension-free state all the time, and the situation that when the opening amount of a traditional expansion joint is increased, the expansion joint is in a tension state, and damage is caused is avoided.
本发明提供了一种装配式无拉力伸缩装置，涉及桥梁技术领域，该装配式无拉力伸缩装置用于设置于相邻两梁体之间的伸缩缝处，包括第一锚固块、第二锚固块和弹性体，第一锚固块和第二锚固块用于分别设置于相邻两梁体上，弹性体的材料包括聚氨酯复合材料，弹性体设置于第一锚固块和第二锚固块之间并处于压缩状态，弹性体用于覆盖伸缩缝。本发明无论伸缩缝的开口量增大或者减小，弹性体始终处于无拉力状态，避免了传统伸缩缝开口量增大时，伸缩缝处于受拉的状态，而导致损坏。
