Abstract:
A connector for prefabricated structures, comprising:(a) a first connector with six unit members vertically jointed one another to have eighteen jointed surfaces, comprising a central connecting part, including a first boss part with a first coupling hole protruded in a side and a hinge part with screw holes in both ends created; a tetrahedral connecting part where the hinge part of the central connecting part and the both ends in the other side of the central connecting part are created in a unit steep at predetermined angles; the second boss part with the second coupling hole formed as protruded in a center of the tetrahedral connecting part to the same direction with the first boss part of the central connecting parts; a plural hinge parts with insertion holes where bolts are inserted are separated in one end to be arranged in both sides of the hinge part of the central connecting part; and (b) a second connector, comprising: a base including a coupling part formed as protruded in a center of the one side of the coupling part, having a third coupling hole pierced to correspond to the second coupling part of the first connector in the center of the coupling part; a plurality of the seating part formed as protruded by being separated at equal intervals in the external surface of the coupling part; a projected part formed as protruded to the direction of the circular cylinder higher than the coupling part and the seating part in one side of the seating part; a plurality of recesses formed at equal intervals on the projected part; a support rod formed steep toward the outside on the other surface of the base at equal intervals; a connecting part with a holding protrusion to be held with insertion of the joint members by being formed in a unit on the external phase of one end of the support rod; and a lamp support part for supporting a light means by having the external surface of the lamp support part formed in a unit to be close to an internal surface in one end of each support rod.
