Embodiment 1 A concrete block 1 having a fitting recess 2 at a lower portion and a convex portion 3 having a tapered side surface at an upper portion, wherein a fitting recess 2 formed below one concrete block 1 is provided. The convex portion 3 having a tapered side surface provided above the other concrete block 1 has a size and a shape that can be fitted to each other. A vertical base plate 4 corresponding to a plurality of vertical lengths of the concrete block 1 is formed, and tapered both side surfaces 5, which can be fitted into fitting recesses formed in the lower part of the concrete block, are formed on the upper part of the vertical base plate 4. 5 is provided. In the longitudinal direction of the vertical base plate 4, a plurality of reinforcing reinforcing bars 7 are penetrated and buried, and a through hole 9 for allowing the vertical reinforcing bar 8 to pass through the center of the width of the vertical base plate 4. The base plate 10 for holding the concrete block of the present invention is formed by providing the base plate 10 at a plurality of locations.

FIG. 4 shows a projection 3 having a fitting recess 2 at a lower portion and a tapered side surface at an upper portion as described above.
And a fitting concave portion 2 formed below one concrete block 1 and a convex portion 3 having a tapered side surface provided above another concrete block 1 are mutually fitted. FIG. 5 shows a concrete block having a fitting recess 2 only in the lower part.

Generally, since the position of the vertical reinforcing bar 8 is hard to be specified, it is preferable to form the vertical slot 9 in a vertically long groove shape so that the reinforcing bar can penetrate the reinforcing bar at any position. Therefore, the holding plate 10 for holding the concrete block is configured such that one or a plurality of reinforcing bars are buried in the longitudinal direction of the vertically long base plate 4 and one or a plurality of through holes 9 are provided in a central portion of the width. It is something to be done.

At the time of stacking concrete blocks, for example, a base block 10 for holding concrete blocks is horizontally fixed on the upper surface of the base concrete, horizontal soil finish 20. The lowermost row of concrete blocks is guided by successively fitting the fitting recesses 2 provided at the lower part of the concrete block 1 guided along the tapered sides 5, 5 on both sides of the vertically long base plate 4 constituting the holding base plate 10. Is completed.

As shown in FIG. 1, the fitting recess 2 of the concrete block 1 and the vertically long base are formed so that a gap of the joint 15 is formed between the lower part of the concrete block 1 and the upper surface of the foundation concrete. If the height of the plate and the convex portion 6 are selected, the base plate 10 for holding the concrete block can be obtained.
Is fixed to the upper surface of the base concrete and horizontal soil finish 20, and if the projection 6 is fitted to the fitting recess 2 provided at the lower part of the concrete block 1, the gap between the joints is automatically adjusted. When the joints 15 are filled in the gaps between the joints, the concrete block 1 and the concrete block holding base plate 10 are securely fixed to the upper surface 20 of the foundation concrete. In the case of the concrete block as shown in FIG. 5, if the lowermost concrete block 1 and the holding base plate 10 are fitted and fixed, each of the upper concrete blocks is a conventional concrete block having upper and lower flat plates. It can be used.

[0015]

Embodiment 2 In order to further increase the strength of the concrete block holding base plate of the present invention, both sides are formed on the upper surface of a rectangular base 11 having a predetermined thickness and a width substantially equal to the width of the concrete block. And a trapezoidal vertically long platen 12 formed integrally with a taper, and a reinforcing bar 13 corresponding to almost the entire length of the long rectangular base 11 and the trapezoidal vertically long platen 12 is provided inside the long rectangular base 11 and the trapezoidal vertically long plate. A vertical slot 14 is formed at the approximate center of the width of the longitudinal rectangular base 11 and the trapezoidal vertically long plate base 12 so as to penetrate the vertical reinforcing bar. Also in this case, as shown in FIG. 6, when the concrete block 1 and the trapezoidal vertically long platen 12 are fitted,
If the gap between the joint portions is formed, the fixing between the concrete block 1 and the trapezoidal vertically long platen 12 is stabilized by the joint portions 15.

According to the first aspect of the present invention, a concrete block having a fitting concave portion at a lower portion and a vertically long base plate having a plurality of lengths of the concrete blocks are formed. The upper part of the board is provided with a convex part which can be fitted into the fitting concave part formed in the lower part of the concrete block, and one or two or more reinforcing bars are penetrated in the longitudinal direction of the vertically long base plate. Since one or more vertical holes for reinforcing bars are formed at one or more places in the center of the width of the plate, for example, when laying a concrete block fence, eliminate waste of concrete material for fastening and lay the lowermost concrete block. Can be laid very easily and quickly horizontally even by amateurs without skill, and with the fitting recess of the bottom concrete block,
Since the projections of the vertically long base plate of the holding base plate for the concrete block are combined, when the concrete blocks are stacked, a concrete block wall excellent in earthquake resistance and collapse resistance can be formed. Further, in the concrete block holding base plate according to the second aspect, since the longitudinal base plate is tapered on both sides on the longitudinal side and has a substantially trapezoidal cross section, handling is extremely easy and strength is reduced in a short time. This enables construction of an excellent concrete block. According to the concrete block holding base plate of claim 3, the vertical base plate has a tapered shape on both sides on the long side in the upper inner portion of a flat long rectangular substrate having a width substantially equal to the width of the concrete block. Since it is a substantially trapezoidal convex portion, the holding plate itself for holding the concrete block is reinforced more strongly.
