Abstract

The invention discloses a load-bearing and monitorable shear and non-pull-resistant piston type expansion joint device, which comprises an I-beam and a telescopic member; rubber layers are fixed on both sides of the web plate of the I-beam and the inner side of the flange plate; The number of telescopic members is multiple, and they are arranged at equal intervals along the length of the I-beam; the retractable members pass through the web of the I-beam, and the two ends are respectively used for fixed connection with the connecting members on both sides of the I-beam. The invention adopts the I-beam and the telescopic member to form an expansion joint device with a telescopic function, which ensures the free expansion and contraction performance between the adjacent connecting members; the rubber is embedded in the gap between the I-beam and the connecting member to improve the The continuity of the overall structure and the durability of the telescopic device are improved.

Description

technical field [0001] The invention relates to the field of expansion joint devices for bridges and super-long structures, in particular to a novel expansion joint device that improves the mechanical performance of the structure, improves the continuity and durability of the structure, and can monitor the deformation of the structure along the axial direction. Background technique [0002] The bridge or super-long building structure is affected by temperature changes, and the thermal expansion and cold contraction of the structural material may cause problems such as local extrusion deformation and excessive shrinkage cracks in the structure. Comfort has a greater impact. Therefore, in order to reduce the adverse effects of thermal expansion and cold contraction, expansion joints are usually used in the structure to preset the free expansion and contraction distance along the axis direction for the structure, so as to ensure the stability of the structure and reduce the str...
