Abstract

The invention discloses a bearable and monitorable shearing-resistant non-pulling-resistant piston type expansion joint device which comprises I-shaped steel and telescopic components, wherein rubber layers are fixed on two sides of a web of the I-shaped steel and the inner side of a flange plate; the multiple telescopic components are arranged in the length direction of the I-shaped steel at equal intervals; the telescopic components pass through the web of the I-shaped steel, and the two ends of each telescopic component are fixedly connected with the connecting components on the two sides of the I-shaped steel respectively. According to the invention, the telescopic joint device with the telescopic function is composed of the I-shaped steel and the telescopic components, and the free telescopic performance between the adjacent connecting components is guaranteed; thus, the rubber is embedded in the gap between the I-shaped steel and the connecting component, so that the continuity of the whole structure and the durability of the telescopic device in use are improved.

Description

Technical field [0001] The present invention relates to the field of bridges and ultra-long structures, which relates to an improvement of structural dependent performance, increasing structure continuity, and durability, and can monitor structurally deformed sewing devices in the axial direction. Background technique [0002] The bridge or ultra-long building structure is affected by temperature changes. The thermal expansion of structural materials can cause local extrusion deformation, and there is an excessive shrinkage crack. These problems have the service safety of bridges and ultra-long building structures. Comfort has a greater impact. Thus, in order to reduce the adverse effects of thermal expansion, the structure is generally used as the free telescopic distance in the axial direction of the structure in the axial direction, thereby ensuring the stability of the structure, reducing the stress and deformation of the temperature. However, if the telescopic seam is handle...
