The present invention relates to a connecting device for a precast block, wherein a concrete block body part has a connection space groove part to make a staircase shape with the connection surfaces and a rod screw thread. A pair of precast blocks has individual connection rods buried in the block body part to make the rod screw thread be exposed over a bottom surface in a line with the connection surfaces of the connection space groove part. A female joint part is installed on a connection rod of one precast block. A male joint part is installed on a connection rod of the other precast block. The connection rods are fastened together when connecting the pair of precast blocks together to make the connection surfaces come in contact with each other. Therefore, a female coupler is easily joined to the male coupler even when the connection rods of the precast blocks cross each other while the connection surfaces are in contact with each other. |
