PROBLEM TO BE SOLVED: To provide an assembled structure of a parallel-cross frame which enables a three-dimensional structure to be constructed by effectively utilizing a large amount of lumber such as lumber from thinning and speedily, inexpensively and simply performing construction. SOLUTION: The double parallel-cross frame 2 is formed by assembling pieces of lumber 1 juxtaposed at required intervals in parallel crosses. Supports 3 inserted into corner holes 21 at four corners of the parallel-cross frame 2 are continuously provided on the ground, and the plurality of parallel-cross frames 2 are fitted and inserted into the supports 3, stacked, and connected to one another, so that the upper and lower parallel-cross frames 2 can be displaced from each other by a predetermined dimension in the direction of the continuous provision of the supports 3.
