Abstract

This application specifically relates to a joint structure of a pontoon bridge. The joint includes an ear plate, which is set on the edge of the ear plate as a semi-circular arc, and a hole is also provided in the ear plate, wherein the center of the semi-circular arc and the center of the hole There is a gap, which improves the shear strength of the joint; the two sides of the lug plate are respectively equipped with an upper transition plate and a lower transition plate; , so that the tensile force on the joint is transmitted smoothly, avoiding stress concentration, reducing the tensile stress on the lug plate, thereby improving the tensile strength of the joint; isolating the lug plate from the main keel structure of the pontoon bridge, thereby avoiding the problem of complicated and difficult to implement welding processes and the cross-section The stress concentration caused by the sudden change improves the fatigue resistance of the joint.

Description

technical field [0001] The present application relates to the field of pontoon bridges, in particular to a joint structure of pontoon bridges. Background technique [0002] Pontoon bridge refers to a bridge that uses boats or pontoons instead of piers and floats on the water. [0003] The pontoon bridge is a decomposable device assembled on site, and a connecting device is arranged between the bridge node boat bodies of the pontoon bridge. The type of connection device directly affects the speed of the connection operation and the performance of the equipment, and the joint is a key component of the pontoon. [0004] like figure 1 As shown, the joint 100 is connected with the transition plate by using the lug plate 1, and the connection between the joints 100 can be realized along the hole 1b of the lug plate 1, but the section between the lug plate hole 1b and the semicircular arc 1a bears All shearing forces are prone to breakage and affect use.
