SOLEPLATE FOR AMENDING ECENTRICITY AND PROTECTING PUNCHING OF TENSION RING TRUSS FOR LARGE-SCALED DOME ROOF STRUCTURE

摘要

PURPOSE: A sole plate for correcting the eccentricity of a tension ring truss and preventing the tension ring truss from being punched for a large-scaled dome roof structure is provided to weld the lower chord of a tension ring truss to the top of a column by flattening the top of the column. CONSTITUTION: A sole plate for correcting the eccentricity of a tension ring truss and preventing the tension ring truss from being punched for a large-scaled dome roof structure comprises a bottom plate(110) and a top plate(120). The bottom plate is formed in a square plate shape using a metal material. Multiple slots are formed on both ends of the bottom plate. The center of the bottom plate is welded to the top of a column. The top plate is formed in a rectangular plate shape using a metal material. Latticed end protrusions(121) and bolt holes are formed on the top of the top plate. The end protrusions have the same curvature as the lower chord(5) of a tension ring truss. The bolt hole corresponds to the slots of the bottom plate. The top plate is moved on the top of the bottom plate along the slots in the eccentric direction of the tension ring truss.
