Abstract

The invention belongs to the technical field of bridge engineering parts and specifically relates to a self-stabilizing rapid-mounted bridge expansion and contraction device and a mounting method thereof. The self-stabilizing rapid-mounted bridge expansion and contraction device specifically consists of symmetrically arranged bridge expansion and contraction device single bodies; a rubber strip for bridge expansion and contraction is arranged between the bridge expansion and contraction device single bodies; each bridge expansion and contraction device single bodies comprises a box body, a plurality of first sleeves and vertical pins, wherein the plurality of first sleeves are arranged in the box body, and the vertical pins are arranged in the first sleeves; the upper parts of the verticalpins are inserted and embedded into the first sleeves; glue injection holes are formed in the upper surface of the box body; and the glue injection holes communicate with the first sleeves. The self-stabilizing rapid-mounted bridge expansion and contraction device has the advantages of high quality, long service life, easy mounting, short mounting period, free maintenance, convenient changing, broad market application prospect and the like.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering components, and in particular relates to a self-stabilizing and quick-installing bridge expansion 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 br...
