CB200
ZHONGHAI
ZHQL-CB200
The basic components of ZB-200 type steel bridge can be divided into main beam structure, bridge deck system, support connection structure and bridge end structure. The main beam structure is composed of truss unit, truss pin (including safety pins) and reinforced string; the bridge deck system is composed of beam, bridge plate and curb; the support connection structure is composed of horizontal support frame, vertical support frame and wind resistance rod; and the bridge end structure is composed of end column, lower bridge seat and seat plate.
The high shear unit is mainly used as the truss unit of the bridge with large shear force. In the structure, except for the vertical rod and the belly rod using 56080 rectangular hollow steel, the other components and main dimensions are the same as the standard truss, and the high shear truss unit weighs 348 ㎏.
The high shear truss unit can also be used as a bridge middle bridge joint for assembly into a special bridge. As a special bridge.
In order to ensure the interchangeability of the truss unit, the tolerance of unit connection size should be strictly controlled; to reduce bridge weight deflection, the hole on the upper chord can be processed at the positive tolerance, and the lower chord should be processed at the negative tolerance, with the deflection of 1mm.
