A system support is provided to facilitate support of loads in vertical direction while equally distributing loads by constantly maintaining gap between vertical members, by tightly joining the horizontal member to the vertical member. A system support comprises a plurality of hollow vertical members(100), a joint(200), and a horizontal member(300). The joint comprises a plurality of slots in a circumferential direction to join the vertical members in vertical direction when an end portion of each different vertical member is inserted to a body, and a support plate integrated to an outer diameter of the body to prevent opposite ends of the vertical member from coming in contact with each other. The horizontal member is installed between the vertical members, and joined to the slot by a connection unit which comprises a facing surface and a tapered surface that are capable of progressively increasing joining force of the horizontal member with respect to the vertical member. When the horizontal member is vertically inserted to the slot of support plate, the tapered surface of the connection unit allows the horizontal member to move in horizontal direction, coming in contact with an outer diameter of an end portion of the vertical member, thereby increasing the joining force of the horizontal member for the vertical member.
