DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a method for constructing a wall using a construction block according to the present invention will be described with reference to the drawings. First Embodiment FIGS. 1 to 8 show one embodiment (first embodiment). First, FIGS. 1 to 3 show a construction block mainly applied to a wall or a wall. That is, FIG. 1 shows the whole block body, and FIGS. 2 and 3 show members used in the block body. The block body H includes two side plates 1 arranged to face each other and a connecting member 2 connecting the side plates 1. Hereinafter, the detailed configuration of each member will be described.
The side plate 1 is formed of an appropriate hard material such as concrete, tile or synthetic resin, has a predetermined thickness, and has a rectangular shape. Reference numeral 10 denotes a surface of the side plate 1;
Is subjected to cosmetic processing. 11 is the back surface. On the upper and lower and side surfaces of the side plate 1, there are formed step portions 12 which engage with other side plates 1 arranged in the vertical and horizontal directions.
On the back surface of the side plate 1, a plurality of vertical grooves, that is, dovetail grooves 13 are provided vertically at predetermined intervals along the width direction. The connecting member 2 includes a flat plate 3, a vertical member fixed on both sides of the plate 3, that is, a dovetail member 4, an engagement recess 5 fixed on the upper part of the plate 3, An engaging protrusion 6 fixedly provided at a lower portion of the abdominal plate 3. More specifically, the abdominal plate 3 has a predetermined rigidity with a predetermined thickness, and an opening 15 is formed at the center. The width of the abdominal plate 3 determines the distance between the side plates 1. The dovetail member 4 is fitted into the dovetail groove 13 of the side plate 1.
16 is a shelf board. The engaging recess 5 has a base 5a and a crimping portion 5b.
Made of an elastic material. Base 5a
Is fixed to the abdominal plate 3 and the shelf 16 stretched from the abdominal plate 3. The engaging projection comprises a base 6a and a wedge 6b.
The base 6a is fixed to the abdominal plate 3 and has rigidity. Thus, the side plate 1 and the connecting member 2 are assembled as shown in FIG. That is, the dovetail member 4 of the connecting member 2 is fitted into the dovetail groove 13 of the side plate 1. Both are firmly fixed via an adhesive. The side plates 1 are connected to each other by two or more (two in this embodiment) connecting members 2, so that the side plates 1 become independent and maintain required rigidity. FIG. 4 shows a state in which the blocks H are vertically assembled. That is, each block body H is placed in the same phase state in the vertical direction. When the upper block H is placed on the lower block H, the wedge portion 6b of the engaging projection 6 is The crimping portion 5b of the engaging recess 5 is pushed and expanded and fitted,
Thereafter, the crimping portion 5b of the engaging recess 5 presses against the engaging protrusion 6 by its elasticity. In this state, concrete is inserted into the hollow portion of the block body H (this is called filled concrete).
Is pressed, the crimping portion 5b of the engaging recess 5 is restrained by the filled concrete, thus preventing the engaging protrusion 6 from coming off.

An example of a method of constructing a wall using the block body H will be described below in accordance with a construction procedure. (1) The base concrete B is cast at the position where the wall is to be constructed, and the connecting reinforcing bar 17 is embedded along the center line of the wall so as to protrude from the upper surface of the base concrete B.
In this state, the block body H (which is referred to as a foundation block body) having the lower end surface of the side plate 1 as a flat wall and having no engaging projection 6 is held in the hollow portion so as to hold the connecting reinforcing bar 17.
It is placed on the upper surface of the foundation concrete B, and a plurality of these block bodies H are arranged side by side. At this time, since the side surfaces of the block bodies H are the step portions 12, they are fitted to each other and are arranged closely. (2) Next, the second-stage block body H is placed on the base block body H with the same phase. At this time, since the positions of the engagement recesses 5 and the engagement protrusions 6 in the upper and lower block bodies H are on the same vertical line, as described above, the engagement protrusion 6 of the upper block body H is The block H is fitted into the engagement recess 5. The positions of the upper and lower blocks H are also aligned by the steps 12. (3) Thereafter, the first-stage and second-stage block bodies H
The intermediate concrete 18 is filled in between. The filling concrete 18 is filled in the middle of the upper block H. Then, due to the filling of the filling concrete 18, the crimping portion 5 b of the engaging concave tool 5 strongly presses the wedge 6 b of the engaging convex tool 6 by the filling pressure, and the upper block body H
Is prevented from falling out. The effect is further increased with the consolidation of the concrete 18. (4) Further, the block bodies H are stacked on the upper stage, and the filling concrete 18 is cast in the same manner as in (3) to construct a wall body. In the above-described process, the upward stacking of the block body H is prevented by collapsing, and it is free to place the filled concrete 18 thereafter. The wall constructed in this way is filled with concrete 1
By solidifying 8, the wedge portion 6b of the engagement convex 6 is firmly restrained via the crimping portion 5b of the engagement concave 5, and exerts a strong resistance against falling. This restraining force is exerted on each block body H and is exerted on the whole wall body. Therefore, in the construction of a wall body using the present block body, the same strength as that of the concrete block wall body with the conventional reinforcing steel bar can be obtained without using the reinforcing steel bar. It is possible,
There is an advantage that construction efficiency is improved.

FIG. 5 shows another embodiment of the connecting member included in the block body applied to the first embodiment. In this connecting member 2A, an engagement recess 5A and an engagement protrusion 6A are attached to the upper and lower portions of the abdominal plate 3 along the longitudinal direction of the abdominal plate 3. The engagement recesses 5A are provided with crimping portions 5b opposed to each other, and the wedge portions 6b of the engagement projections 6 are resiliently inserted between the opposed crimping portions 5b. FIG. 6 shows still another embodiment of the connecting member. In this connecting member 2B, the abdominal plate 3
A has flexibility, and flange plates 20 are fixedly provided at both ends of the abdominal plate 3A instead of dovetail members. More specifically, a flexible plate 21 having a curvature is interposed at the center of the abdominal plate 3A. At the lower end of the flange plate 20, an engagement protrusion 6 that fits into the engagement recess 5 is fixedly provided. The connecting member 2B is used by being interposed in a hollow portion K of a normal lightweight concrete block body J. The connection member 2B is fixed by pressing the flange plate 20 against the inner wall of the block body J. After assembling the block bodies J together, filling concrete is cast and a wall body is constructed.

In other words, one end of the flange plate 21 is fixed to one connecting member 2C so as to abut the side plate 1 along the side plate 1, and
At the other end of the flange plate 21, an engagement recess 5C composed of a base 5a and a crimping portion 5b is fixed via the base 5a.
Further, a flange plate 22 similar to the engaging recess 5c is fixed to the abdominal plate 3 on the other connecting member 2C ', and the flange plate 22 has a crimping portion of the engaging recess 5C. An engaging protrusion 6C to be fitted into 5b is fixedly provided. The height of the engagement recesses 5C and the engagement protrusions 6C may be smaller than the height of the side plate 1, but is usually about 1/2 to 1/3.
In this case, it is needless to say that the components are arranged at the same position. Also,
It is also possible to adopt a mode of disposing a plurality of pieces in the vertical direction. Thus, when these block bodies H1 are arranged in the horizontal direction, the engaging recess 5C and the engaging convex 6 between the adjacent block bodies H1 are arranged.
C is fitted, and after that, the engaging portion is restrained by the filling concrete poured into these hollow portions, thereby forming an integral wall. This mode is effective for a block body in which the height of the block body H1 is large. FIG. 8 shows another block body H2 included in this embodiment. In the block body H2, a dovetail-shaped ridge 13A is formed to protrude from the wall surface of the side plate 1, and a dovetail groove member 4A fitted to the ridge 13A is provided at both ends of the abdominal plate 3 in the connecting member 2D. The connection member 2D is fixed and the intermediate flange plate 23

Are formed thin and inclined downward toward the rear wall 26. At the opening of the engaging recess 5E, its length a
Is larger than the width d of the engaging projection 6E, and the width b of the upper part is
Is sufficiently larger than the maximum thickness e of the engaging projection 6E, and the width c of the lower portion is slightly smaller than e. Thereby, the front wall 28 has some elasticity. Thus, the engaging projection 6E
Is inserted into the engagement recess 5E by pushing and expanding the front wall 28 of the engagement recess 5E, and the upper surface of the wedge portion 6E of the engagement protrusion 6E against the pulling force. And the lower side of the front wall 28 is engaged to resist the pulling force. Thus, the connecting member 2E itself has pull-out resistance. Further, when the consolidating material 30 is filled in the engagement recess 5E, the pull-out resistance further increases (FIG. 9B).
reference). FIG. 9C shows another embodiment of the engagement recess 5E. The front wall 28 of the engaging recess 5E is not inclined, but is formed to be thin to have flexibility. When the engaging protrusion 6E is inserted, the front wall 28 is expanded by its flexibility,
Allows easy insertion. After the engagement convex 6E is inserted, the state returns to the original state, and the pull-out of the engagement convex 6E is prevented.
