Multidirectional error-adjustable node suitable for suspend-dome space structure

The invention discloses a multidirectional error-adjustable node suitable for a suspend-dome space structure. The node comprises a bracket, adjusting pieces, vertical spacing bolts and other devices and fittings, wherein the adjusting pieces are fixed on the bracket through the vertical spacing bolts to from a node entirety; and error adjustment is realized through the adjusting pieces. The invention has the advantages as follows: three-dimensional multidirectional adjustment of the node and a lattice shell rod piece connected with the node can be carried out in the horizontal direction, the vertical direction and the axis direction of the rod piece, so that the length of the rod piece and the spatial geometric position of the node can be adjusted; and through the adoption of the node, construction errors and structural defects are reduced, the stable bearing capacity of a structure is effectively improved, and the safe use of the structure is ensured.
