Spherical curved surface single-layer reticulated shell node

The utility model belongs to a spherical curved surface single-layer reticulated shell node in the field of civil engineering structures. According to the technical scheme, six rod pieces with rectangular sections are intersected at the same center point; wherein the two rod pieces are in butt joint and are communicated with each other to form a through rod piece; a central stiffening plate is arranged at the middle butt joint of the through rod pieces; the central stiffening plate is perpendicular to the penetrating rod piece, and two sides of the central stiffening plate extend out of the penetrating rod piece; the other four rod pieces are symmetrically arranged, and the ends of the other four rod pieces are obliquely connected with the through rod pieces and the central stiffening plate; the upper panel and the lower panel are respectively arranged on the upper surface and the lower surface of the central point of the six rod pieces; the six rod pieces in the middle are clamped by the upper panel and the
