The present invention adopts main couple and the upper and lower joint form of transition truss, main couple and transition truss are overlapped, transition truss is overlapped on main couple, poor according to the overlap height of transition truss and main couple, first profile needed for its assembly welding transition truss lower chord, and reinforcement is made to each stress point, in order to install more smoothly, first by lower chord assembly welding, reach required profile, postwelding processing makes installation process more smooth, and the place heavy to stress point does to strengthen making overall structural stability stronger.
On the basis of technique scheme, the present invention can also do following improvement.
Further, be provided with metal sheet in the junction of described vertical rod and brace and upper chord and lower chord, vertical rod and brace and upper chord and lower chord are fixed together by screw by described metal sheet.
Adopt the beneficial effect of above-mentioned further scheme to be use such type of attachment, top-bottom chord can be made to connect more firm, add the soundness of aluminium alloys overline bridge.
Further, connecting points is provided with bottom described fixed bearing.
Further, movable sliding is provided with bottom described freely movable bearing.
The present invention adopts the joint form of main couple and excessive truss, and the link of lower chord side is provided with fixed bearing, is provided with connecting points bottom fixed bearing, can match, be fixed together with the bolt on main couple; The link of lower chord opposite side is provided with freely movable bearing, is provided with movable sliding bottom freely movable bearing, and can match with the bolt on main couple, bolt can slide in movable sliding, fixes after adjustment again.
The beneficial effect of above-mentioned further scheme is adopted to be that transition connecting apparatus is connected on main couple by use two kinds of bearings (fixed bearing and freely movable bearing), can both main difference be just move, fixed bearing is irremovable, the form be fixedly connected with is adopted to be connected on main couple, freely movable bearing is then different, bolt can slide in movable sliding, when expanding with heat and contract with cold by Changes in weather, freely movable bearing can be regulated back and forth by movable sliding and reach desired location, be connected on main couple, there is stronger stability and practicality.
