PROBLEM TO BE SOLVED: To provide a construction method of precast concrete that can save labor and shorten the construction period by employing an encapsulated adhesive being broken with a predetermined pressure for an adhesive applied between each block. SOLUTION: The end adjacent surface 4a of each block 4 is applied with a minutely encapsulated pressure sensitive adhesive consisting of a major agent and a curing agent, and each block 4 is brought in contact integral with each other such that mutual blocks are contacted in close relation by straining a post tension cable inserted in the inside of the block 4. The post cable is adapted to put the mutual blocks 4 in close contact with each other by connecting the block 4x on a support 1 and the block 4y in one span distal part, and straining the inner cable and outer cable with a predetermined pressure, or, in this instance, a pressure sensitive adhesive being minutely encapsulated and applied on the end contact surface 4a of each block 4 is broken, resulting in a mixture and hardness of the major agent and curing agent. |
