Stating truss body includes top boom, lower boom and more middle web members, and the middle web member is located between top boom and lower boom and connected
Connect chord member and lower boom；The device also includes being located at the outer bar on the outside of lower boom and the connection component for fixing outer bar, institute
State connection component and be removably attached to lower boom and outer bar respectively, and the connection component be located at lower boom be used for
The node location of middle web member connection.
Further, the outer bar is parallel to lower boom.
Further, " V " shape structure is formed between the two neighboring middle web member.
Further, the top boom, lower boom and more middle web members using i shaped steel or box shaped steel and pass through weldering
The mode of connecing is connected.
Further, the outer bar uses i shaped steel or box shaped steel.
Further, the connection component is located at including connecting tube, the fixed interior connecting plate being located on the inside of connecting tube and fixation
Outside link plate on the outside of connecting tube, connected between the interior connecting plate and lower boom and between outside link plate and outer bar by bolt
Connect.
Further, the connecting tube is circular and hollow-core construction steel-tube construction.
Further, the interior connecting plate is symmetrical arranged with outside link plate and is steel plate structure.
The beneficial effects of the utility model：
The anti-ship collision device of bridge of truss structure of the present utility model, due to being additionally arranged outer bar, outer bar on the outside of lower boom
Buffer action is played, when ship collision accident occurs, ship contacts with outer bar first, and its impact is delivered to connection component, then
It is delivered to main couple body；Among collision process, outer bar and connection component can occur to be plastically deformed and absorb energy, reach and subtract
The effect of few ship deformation, is arranged at the node of main body truss structure plus connection component, axle power is only produced to truss body,
Rod member out-of-plane deformation additional force is avoided, can effectively protect joist body structure；Meanwhile connection component removably connects respectively
Lower boom and outer bar are connected to, installation and replacing are convenient.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples：
