This corresponding reduction；On the one hand lower pair of chord member of steel pipe web member and steel pipe can provide template action for its inner concrete, on the other hand
Deformation during concrete compression can be limited, the anti-pressure ability of concrete and the bearing capacity of structure is enhanced；Steel pipe web member and steel
Lower pair of chord member of pipe is welded to connect, and eliminates the connecting elements of complexity, makes structure stress more succinct, constructs convenient；Steel pipe abdomen
Do not connect between lower pair of chord member of bar and steel pipe, both inner concretes are each integral, tamping be more easy to during pouring concrete within steel pipe,
Generation cavity is avoided the occurrence of, makes structure stress more uniform；Lower pair of chord member section of steel pipe is square, and upper flat can be its top
Steel pipe web member provide excellent support when constructing, reduce live support and set up, construct convenient reduction of erection time；Lower pair of chord member of steel pipe
Between using K-type stull connect, the globality and stability of structure are further enhanced.
