Large-span square steel pipe truss and accumulative sliding construction method thereof
The invention discloses a large-span square steel pipe truss and an accumulative sliding construction method thereof. The large-span square steel pipe truss comprises two upper chord members and two lower chord members. The upper chord members and the lower chord members are parallel to each other, wherein no upper chord member is coplanar with the two lower chord members. The upper chord members are connected with the lower chord members through a plurality of inclined web members. The upper chord members are connected through a plurality of supporting rods, and the lower chord members are connected through a plurality of supporting rods. The two ends of each upper chord member are provided with supporting bases. The supporting bases are perpendicular to the upper chord members. According to the large-span square steel pipe truss, the two ends of each upper chord member of the truss are provided with the corresponding supporting bases, the force bearing point of the truss is arranged at the upper portions, namely, the upper chord members, of the truss, and therefore the after-construction overall height of the truss can be reduced, and the influences of the limit of construction space on the truss are reduced; in addition, the force bearing point of the truss falls onto the supporting bases, the truss bears the acting force exerted by an ejecting and pushing device during sliding and deforms, and the overall structure of the truss is influenced.
