Method for positioning spatial structure sphere node and localizer

The present invention provides a method for locating the node of the spatial structural sphere, the method is equivalently transferring the sphere center of the special sphere which can not be measured, and converting the three-dimensional special coordinate of the sphere center to two-dimensional plane coordinate and out-of-plane relative scale height, in actualizing all sphere centers are whollyprojected and converted to the horizontal reference plane, in installing the plane position of the sphere center is arranged at the upper side of the plane, and a sphere center is arranged at the position which is at vertically upside or downside of the plane position, namely the sphere center of the node of the actual spatial structural sphere. The locator is composed of a base frame formed by vertically welding the sleeve on the baseboard, a top holder formed by vertically welding the screw bolt on the roof plate, a nut matched with the screw bolt and a bolt, the nut is movingly located atthe upper end of the sleev
