The invention discloses an assembly type homestay space structure connection node. The connection node comprises a support column. A vertical joint is arranged on the top of the support column, and horizontal joints are arranged on both sides of the support column. The vertical joint and horizontal joint are integrated as a whole with the support column. The support column comprises with three parallel set first wing plates. The first wing plates adjacent are connected through the first web, in the middle of each first web is provided with a pipe body, the upper end surface of each first wing plate is provided with a wiring board, the horizontal joint comprises two second wing plates and two second webs, the outer end surface of each web is arranged on a wiring board. The connection node has the advantages of light weight, energy saving, environmental protection, fast construction speed and high industrialization degree and the like. The connection node can effectively solve the problems of low construction industrialization level, low labor productivity of housing construction and low quality of traditional housing products so as to adapt to the development of China's construction industry.
