In the figure, 1 is a tray and 2 is a rigid block. The tray 1 has a large number of bottomed chambers 3. Each bottomed chamber 3 is defined by a bottom wall 5a and a peripheral wall 5b.

The rigid block 2 is held in each bottomed chamber 3. The rigid block 2 is constructed of a block mainly made of cement sand as a suitable material. The rigid block 2 is housed in each bottomed chamber 3 so as to be movable, particularly movable up and down. That is, each rigid block 2 is collected by the tray 1, maintains a relative position using the tray 1 as a medium, and each block is regulated by the peripheral wall 5b and bottom wall 5a of each bottomed chamber 3 while moving along the peripheral wall 5b. Movement in the direction of the opening is possible.

The above-mentioned tray 1 and rigid block 2 are made into a composite by pouring a fluid material mainly composed of cement and sand into each bottomed chamber 3 of the tray 1, and then hardening the fluid material as it is. The tray 1 is made of a synthetic resin material that has good releasability to cement, and allows the weakly bonded blocks 2 to be peeled off and moved freely after hardening.

As another example of compounding, a tray 1 having a large number of bottomed chambers 3 is prepared in advance, and a separately formed rigid pair block 2 is fitted into each bottomed chamber 3.

The upper end of each rigid block 2 protrudes beyond the opening surface of each bottomed chamber 3, or is at least flush with the opening surface.
