Height-adjustable bridge expansion joint component capable of realizing transverse connection

Abstract

The invention relates to the technical field of bridge expansion joints and discloses a height-adjustable bridge expansion joint component capable of realizing transverse connection. The height-adjustable bridge expansion joint component comprises two substrates, the two substrates are symmetrically distributed, the opposite sides of the two substrates are each connected with a plurality of rod parts in a sliding mode, the rod parts are distributed in a linear array mode and are tightly attached to one another, first strip-shaped holes are formed in the surfaces of the substrates, and second strip-shaped holes are formed in the side faces of the rod parts. The bridge expansion joint component is adjustable in height and capable of realizing transverse connection. The two ends of the connecting plate can be fixed in the two grooves by tightening the second bolts. Therefore, connection between adjacent rod parts is achieved, the situation that too long rod parts are customized when the bridge floor is wide is avoided, the production and transportation cost is reduced, the height of the rod parts can be adjusted by sliding the rod parts to change the relative positions of the first strip-shaped holes and the second strip-shaped holes and screwing down the first bolts to fix the rod parts again, and height alignment of the rod parts on the two sides is facilitated.

Description

technical field [0001] The invention relates to the technical field of expansion joints, in particular to a bridge expansion joint component with adjustable height and horizontal connection. Background technique [0002] Bridge expansion joints refer to expansion joints usually set between two girder ends, between girder ends and abutments, or at the hinged position of the bridge in order to meet the deformation requirements of the bridge deck. It is required that the expansion joints can freely expand and contract in two directions parallel to and perpendicular to the bridge axis, and are firm and reliable. The vehicles should run smoothly without sudden jumps and noises; they should be able to prevent rainwater and garbage from infiltrating and blocking; installation, inspection, and maintenance , Elimination of dirt should be simple and convenient. The function of bridge expansion joints is to adjust the displacement and connection between the superstructure caused by ve...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a bridge expansion joint component with adjustable height and horizontal connection, which has the advantages of high strength, low cost and easy adjustment, and solves the need for customized and suitable bridge expansion joint components. length, for bridges with wider decks, long expansion joints need to be customized, and the production cost and transportation cost are high. At the same time, the welding parts used for connection need to be removed when the expansion joints are installed, but the rods on both sides are easy to install after removal. There is a height difference that affects the installation effect
