Abstract

The invention belongs to the technical field of bridge engineering parts, and particularly relates to a self-stabilizing bridge expansion and contraction device and an installation method thereof. Theself-stabilizing bridge expansion and contraction device is composed of symmetrically arranged bridge expansion and contraction device single-bodies, and a rubber strip for bridge expansion and contraction is arranged between the symmetrically arranged bridge expansion and contraction device single-bodies. Each bridge expansion and contraction device single-body comprises a box body, a pluralityof first sleeves arranged in the box body and vertical pins arranged in the first sleeves, internal threads matched with the vertical pins are arranged on the inner sides of the first sleeves, the upper parts of the vertical pins are connected with the first sleeves through threads, and the first sleeves vertically penetrate through the upper surface and the lower surface of the box bodies. The self-stabilizing bridge expansion and contraction device has the advantages of standardized quality, long service life, easy installation, short installation period, no nursing, convenient replacement and the like, and has wide market application prospect.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering components, and in particular relates to a self-stabilizing bridge telescopic device and an installation method thereof. Background technique [0002] Prior art bridge telescoping device, see figure 1 , including a steel beam (40), the steel beam (40) is provided with a ring-shaped steel bar (41), and a plurality of pre-embedded steel bars (42) are pre-embedded on the bridge base. In the process of use, it is first necessary to precisely control the welding position, and weld the ring steel bar (41) of the bridge expansion device and the embedded anchor bar (42) one by one, support the formwork, and then pour high-strength concrete for no less than 14 days. During the maintenance period, the traffic is closed, and vehicles are allowed to pass after the maintenance period expires, that is, the installation of the bridge expansion device is completed. The existing bridge expansion devic...
