が、その筒軸方向に直交方向は、端を揃えて方向性を得
ることとなる。Although the void slab described in each of the above publications has two directions, the layout of the void form is complicated, and its improvement is desired. That is, since each void form has a directivity only in the X or Y direction, for example, in the case of a long cylindrical void form, if the directions coincide with the cylinder axis direction, Can be obtained, but the direction orthogonal to the cylinder axis direction is obtained by aligning the ends.

確に生じる。In order to solve the above-mentioned problems, the present invention provides the void form itself in two directions as a cross in plan view. If it is a cross shape, the XY directionality can be easily obtained by matching the cross direction, that is, the XY directions. If the void form has bidirectionality, the Two directions of the mold section are accurately generated.

一体化したものとし得る。BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention is a void form which is disposed in a slab and forms a cavity in the slab, and which has a cross-shaped configuration in plan view. The void form may be integrated by connecting a plurality of void forms in one direction or in two directions.

For example, when used together with the conventional straight rod-shaped void mold 3, if there is a step, it is arranged as shown in FIG. 3A, and if there is no step, it is arranged as shown in FIG. 3B. In the case of building only with this void form 1, if there is a step,
As shown in FIG. 3C, if there is no step, it is arranged as shown in FIG. In the figure, H is a pillar.

要素解析で使用するグリッドと現物のグリッドが一致
し、解析の適合性が良くなる。In this void slab, the I-shaped cross section is continuous in the two directions of XY and has no directivity. Therefore, the slab cross-sectional rigidity in the X direction and the Y direction are the same, and the slab can be considered as one plate, which simplifies the design. Further, in recent designs, finite element analysis is used, and the grid used in finite element analysis matches the actual grid, and the suitability of analysis improves.
