1. A manifold type pipe structure, comprising:
at least one branch pipe formed at a pipe passage having a flow hole through which fluid flows; a first joint coupler, comprising:
an input coupling part formed at a first end of the pipe passage, and an output coupling part formed at a second end of the pipe passage; a second joint coupler comprising an output coupling part to be joint-connected with a limited rotation angle at the input coupling part of the first joint coupler; and a fixing portion for installing the pipe passage on a ground or a wall, wherein said input coupling part forms a coupling means disposed at an outer surface of the first end of the pipe passage, and said coupling means forms a plurality of engaging protrusions disposed in a curvature direction of an outer surface of the pipe passage to be spaced apart at predetermined intervals to form an engaging space between each of the plurality of engaging protrusions, and the second end of the pipe passage is open and the first end of the pipe passage is sealed, and said output coupling part of the second joint coupler forms an engaging means at the first side of the pipe passage, and said engaging means forms a plurality of coupling protrusions to be spaced apart in a curvature direction of an inner surface of the pipe passage, and when the input coupling part and the output coupling part of the second joint coupler are joint-connected, the plurality of coupling protrusions of the output coupling part are inserted up to the sealed portion of the engaging space, so the input coupling part and the output coupling part of the second joint coupler are coupled with a limited rotation angle, and a locking protrusion is formed at an inner surface of the opening of the pipe passage where the coupling means is formed and at a backside of the engaging means to maintain a joint state as the locking protrusions are engaged when jointing the input coupling part and the output coupling part of the second joint coupler, wherein said fixing portion includes a bracket having a fixing hole on the ground for being fixed on the ground or a wall; a lower fixture integrally formed with the bracket and forms a fixing groove at both sides of a holder of which an upper side is open; and an upper fixture of which a lower side is open to be engaged from an upper side of an outer surface of the space between a plurality of fixing shoulders of the outer surface of the pipe passage, with a fixing protrusion formed at both sides of a lower side of the upper fixture being inserted into the fixing groove, wherein the plurality of fixing shoulders can be inserted into a joint groove formed at an inner surface of the upper fixture when the upper fixture and the lower fixture are engaged between the plurality of fixing shoulders. |
