Pre-stressed concrete combination truss beam
The invention relates to a PSC combination truss beam based on the invention, wherein the truss beam is provided with a pair of beam upper flanges (10) with certain distance in the horizontal direction, a pair of beam lower flanges (20) deviating certain distance from the beam upper flanges (19) towards lower portions, and a pair of webs (30) connected to two sides of the pair of beam upper flanges (10) and the pair of beam lower flanges (20), wherein the beam upper flanges (10) are constituted of reinforcing steel bar concrete layers (13) or reinforcing steel bar concrete layers (13) burred with PS steels; the beam lower flanges (20) are constituted of reinforcing steel bar concrete layers (23) buried with the PS steels (21); the pair of webs (30) enable a truss structure connected to end portions of a plurality of truss members (31) to be mounted as an inverted trapezoidal shape; and node articulated joints (40) are connected between the webs (30) and the beam upper flanges (10), and between the webs (30) and the beam lower flanges (20). According to the invention, the pre-stressed concrete combination truss beam is related to the PSC combination truss beam. Through the pre-stressed concrete combination truss beam, manufacturing and construction are very easy; and through observing the safety at the node positions when the truss beam is in use, the maintenance and the reinforcement to a bridge are easier.
