Description

[Brief explanation of the drawing]

Figure 1 A, B, and C are a partially cutaway plan view, front view, and right side view of the flooring material of the present invention in which the crosspieces are fitted and the utility pipe is piped in the groove for installing the utility pipe. Figure 2 shows the floor of a concrete building before a part of the subfloor material shown in Figure 1 is cut out, and the finishing material with utility pipes installed at right angles to the slab is installed. A partial plan view of the structure is shown. Figures 3A and 3B are partially cutaway plan views of a subflooring material having a groove for installing utility pipes, which has grooves formed linearly in the length direction and grooves perpendicular to each other near the ends. Figure 4 A, B and C show grooves formed linearly in the length direction of the subflooring material, as well as grooves bent in a curved line at right angles near the ends. Fig. 5 shows a partially cutaway plan view, front view, and right side view of a subflooring material having a groove for installing utility pipes. A partially cutaway plan view of the floor structure of a concrete building before it is installed. Figure 6 is a plan view of the entire floor structure of a concrete building with subfloor material laid before applying the finishing material, and Figure 7 is a plan view of the floor structure of the concrete building shown in Figure 6 after the finishing material has been applied. It is a partially cutaway enlarged view of a cross section taken along the line B-B. Figure 8 is a cross-sectional view of a subfloor material with a lid formed on the upper side, and Figure 9 is a cross-sectional view of a subfloor material with a utility pipe installed in the groove for installing the utility pipe in the subfloor material. be. Figures 10A and 10B show a partial cut-out of a subfloor material in which a utility pipe is locked by providing a locking part that projects horizontally on the upper side wall of the groove in at least a part of the groove for installing the utility pipe. A cutaway plan view and a cross-sectional view taken along the line CC are shown. Fig. 11 shows a cross-sectional view of an example of a conventional floor structure for a Western-style room, and Figs. show. Moreover, FIG. 13 is a plan view of the floor structure before the finishing material with the utility pipes arranged in the grooves for installing the utility pipes of the subfloor material shown in FIG. 11 is stretched.
