The construction block X and the wall construction block X having the vertical front panel portion 1 are combined to be vertically stacked. The wall construction block X configured as the inclined panel described above and the wall construction block X configured as the vertical panel may be combined and stacked vertically.

A construction method of the wall surface F (retaining wall) using the wall surface construction block X and the base blocks Y, Y' according to the present embodiment having the above configuration will be described. In this embodiment, the wall surface F has a structure in which the wall surface construction blocks X are stacked vertically in three stages, but a structure in which the wall surface construction blocks X are stacked in two stages or a structure in which the blocks X are stacked in four or more stages may be used.

First, a necessary number of pedestal blocks Y are laid in the left-right direction at a location where the wall surface F is to be constructed, taking into account the width of the wall surface F to be constructed (the number of wall-surface building blocks X arranged side by side in the left-right direction), Of the laid pedestal blocks Y, pedestal blocks Y′ for the sides are laid on the outer side of each of the pedestal blocks Y positioned at the left and right ends, and these adjacent pedestal blocks Y are placed on the sides of the pedestal blocks Y. The pedestal block Y' for the direction is connected via the left and right connecting member 17 (see FIG. 8).

Subsequently, the first-stage wall construction blocks X are placed side by side on the top of the pedestal blocks Y and Y' (the lower surface of the front panel portion 1 and the bottom plate portion 2 of the wall surface construction blocks X are placed on the pedestal. are placed on the blocks Y and Y'), the wall construction blocks X adjacent to each other in the left-right direction are connected to each other via the left-right connecting body 8, and a fixing member 11 is provided on the back surface of the front panel portion 1 ( See Figure 9). The fixing member 11 may be provided on the wall construction block X in advance.

Subsequently, the wall construction blocks X of the second stage are placed side by side on top of the wall construction blocks X of the first stage. When connecting through the body 8 and providing the connecting body 4 to the connecting body fixing portion 5 of each of the bottom plate portions 2 positioned above and below, this connecting body 4 is constructed between the upper and lower wall construction blocks X. In this state, the vertically laminated wall construction blocks X are connected to each other (see FIG. 10). At this time, a fixing member 11 is further provided on the rear surface of the front panel section 1 . The fixing member 11 may be provided on the wall construction block X in advance.

Subsequently, the back-filling material 30 is driven into the space S of the front panel portion 1 (up to the position where the fixing member 11 is embedded) in the first stage wall construction block X (see FIG. 11).

Subsequently, the wall surface construction blocks X of the third stage are placed side by side on top of the wall surface construction blocks X of the second stage. When the connecting bodies 4 are provided in the connecting body fixing portions 5 of the bottom plate portions 2 located above and below while being connected via the connecting bodies 8, the connecting bodies 4 are installed between the upper and lower wall construction blocks X. The wall construction blocks X stacked vertically are connected to each other (see FIG. 12). At this time, a fixing member 11 is further provided on the rear surface of the front panel section 1 . The fixing member 11 may be provided on the wall construction block X in advance.

Subsequently, the backfilling material 30 is driven into the space S of each of the front panel portions 1 of the second-stage wall construction block X and the third-stage wall construction block X to complete the wall surface F (Fig. 13). , 14).

Since this embodiment is configured as described above, the backfilling material 30 is driven into the space S of the wall surface construction block X (front panel portion 1) in a state in which the wall surface construction blocks X are connected vertically. In this case, the wall surface F and thus the retaining wall can be constructed more easily than in the conventional example, such as work without worrying about the stacked wall construction blocks X being displaced or dropped.

In addition, in this embodiment, the connecting body 4 is a rod-shaped body, and the connecting body fixing portion 5 is configured so as to pass through the connecting body 4 and fasten it. It is possible to reliably connect Xs.

Further, in this embodiment, the connecting body fixing portion 5 has openings 5a that open to the left and right side surfaces of the bottom plate portion 2, and is configured so that the connecting body 4 can be arranged through the openings 5a. Therefore, the wall construction blocks X can be easily and quickly connected to each other by using the connecting body 4 .

In addition, in the present embodiment, the front panel portion 1 is provided with an engaging portion 6 at the upper end thereof, and the engaging portion 6 of another wall construction block X laminated at the lower end is engaged with the concave and convex portions. Since the stop portion 7 is provided, the work of stacking the wall surface construction blocks X can be performed satisfactorily.

In addition, in this embodiment, since the bottom plate portion 2 is provided only in the central portion of the rear surface of the front panel portion 1, the vertically stacked wall construction blocks X can be reliably connected to each other. Of course, the weight reduction is achieved because the bottom plate portion 2 has a minimum area for stably standing on its own.

In addition, in this embodiment, on the back surface of the front panel section 1, left and right connectors 8 that can be installed between the front panel sections 1 adjacent to each other on the left and right when the wall construction blocks X are arranged side by side are fixed. Since the left and right connecting body fastening portions 9 are provided for the purpose of this, the work of arranging the wall surface building blocks X can be performed satisfactorily, and the wall surface F can be firmly constructed.

Further, in this embodiment, since the back surface of the front panel portion 1 is provided with the space portion S in which the back-filling material 30 is driven, the wall surface F can be constructed firmly in this respect as well.

In addition, in this embodiment, the rear surface of the front panel portion 1 is provided with a mounting portion 10 for mounting a fixing member 11 which becomes embedded when the backfilling material 30 is driven into the space portion S. Therefore, the wall surface F can be constructed firmly in this respect as well.

It should be noted that the present invention is not limited to this embodiment, and the specific configuration of each component can be appropriately designed.
