The skeleton block described below can be used for various water storage facilities such as rainwater in addition to conventional water storage facilities such as rainwater. Therefore, in the following, description of the water storage facility such as rainwater is omitted, and the skeleton block that is a feature of the water storage facility such as rainwater of the present invention will be described in detail.

FIG. 1 is a perspective view showing an embodiment of the skeleton block of the present invention.
As shown in FIG. 1, the skeleton block 4 shown in this embodiment includes a base 41 having a flat plate shape and a substantially square shape (hereinafter simply referred to as a square) and one diagonal of two diagonal lines on the base 41. Two frustum-shaped support bodies 42 that are erected on the top and have a columnar support body upper end side fitting portion 42a at the tip, and provided on the same base surface as the side on which the support body 42 is erected. In addition, two base side fitting portions 43 on which the support upper end side fitting portion 42a can be fitted are provided on the other diagonal line. In addition, when two skeleton blocks 4 are prepared and the base surfaces on which the support bodies 42 are erected face each other, the pair of skeleton blocks 4 are opposed to each other. The support upper end side fitting portion 42 a located at the position is fitted into the two base side fitting portions 43 of the other skeleton block 4 .

Specifically, as shown in FIG. 2, when the same skeleton block 4 displayed as the third stage is assembled with the support 42 side facing each other up and down, the first skeleton block 4 The support body upper end side fitting portion 42a of the support body 42 is mounted on the base side fitting portion 43 of the second-stage skeleton block 4 placed upside down and on the second-stage skeleton block 4 support body. The support upper end side fitting portion 42a of 42 is fitted to the base side fitting portion 43 of the first stage skeleton block 4, respectively.

FIG. 3 is a longitudinal sectional view showing an example of a state in which the skeleton blocks 4 shown in FIG. 1 are stacked in the vertical direction. The support body 42 of the skeleton block 4 of this embodiment has a truncated cone shape with a taper angle of 2 to 4 ° from the base 41 toward the tip, and the tip end of the support body upper end side fitting portion 42a having a straight column shape. It has become.

The support upper end side fitting portion 42a is provided longer than the depth of the base side fitting portion. If it is too short, there is not enough adhesive margin for fitting, and stable assembly is not possible. If the length is too long, the strength of the skeletal block structure will be adversely affected. Therefore, it is desirable that the length of the base side fitting portion is about 1.5 times as long as the depth of the base side fitting portion. By providing a straight columnar shape at the upper end of the support body without using the frustum shape as it is, the fitting can be performed more reliably, and the cross-sectional area of the fitting portion at the top of the support body can be increased. When the space-retaining skeleton block structure is configured in combination, this structure has the effect of becoming more stable.
