Universal fine adjustment type space grid joint capable of being assembled and construction method

The invention belongs to the field of construction engineering, and relates to a space grid joint and a construction method, in particular to a universal fine adjustment type space grid joint capable of being assembled and a construction method. The universal fine adjustment type space grid joint capable of being assembled and the construction method aim at solving the problems that according to existing grid joints, the adaptability of the same joint to the sectional dimensions and installation directions of different bars can not be achieved, and the standardization degree is low. The universal fine adjustment type space grid joint capable of being assembled comprises a main ring part, a plurality of cushion blocks with edges and a plurality of connecting units, wherein the cushion blocks with edges are arranged on the main ring part in a sleeving mode in the peripheral direction of the main ring part, and each cushion block with edges is connected with an H-shaped steel bar through one connecting unit.
