The side plate 1 is made of an appropriate hard material such as concrete, tile, or synthetic resin, has a predetermined wall thickness, and has a rectangular shape. Reference numeral 10 is a surface of the side plate 1, and the surface 10 is subjected to a makeup process. 11 is the back surface. Side plate 1
Stepped portions 12 are formed on the upper and lower side surfaces of the base plate 1 and the side surface plates 1 are engaged with the other side surface 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 vertically provided along the width direction at predetermined intervals. Connecting member 2
Is a flat plate-shaped abdominal plate 3, vertical members fixed to both sides of the abdominal plate 3, that is, dovetail members 4, engagement recesses 5 fixed to the upper part of the abdominal plate 3, and the abdominal plate 3. Engaging projection 6 fixed to the lower part of the
And consisting of More specifically, the abdominal plate 3 has a predetermined rigidity due to a predetermined thickness, and an opening 15 is formed in the center thereof. 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 portion 6a and a wedge portion 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 surface 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 block bodies H are vertically stacked. 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 body using the block body H will be described below in accordance with a construction procedure. (1) The foundation concrete B is placed at the planned construction position of the wall body, and the connecting reinforcing bars 17 are embedded along the center line of the wall body so as to project onto the upper surface of the foundation concrete B. In this state, the lower end surface of the side plate 1 is made into a flat fence, and the block body H (which is referred to as a foundation block body) without the engaging projection 6 is constructed such that the connecting rebar 17 is held in the hollow portion of the foundation concrete B. Is placed on the upper surface of the block body, and a plurality of these block bodies H are arranged in the horizontal direction. At this time, since the side surfaces of the block bodies H are the step portions 12, they are fitted into each other and arranged closely. (2) Next, the second-stage block body H is placed on the basic block body H with the same phase. At this time, the positions of the engaging concave tool 5 and the engaging convex tool 6 in the upper and lower block bodies H are on the same vertical line, and therefore, as described above, the engaging convex tool 6 of the upper block body H is in the lower part. It fits in the engaging recess 5 of the block body H. The upper and lower block bodies H are also aligned by the step portion 12. (3) Then, the filling concrete 18 is filled between the block bodies H of the first stage and the second stage. The filling of the filling concrete 18 is performed up to the middle of the upper block body H. When the filling concrete 18 is filled, the crimping portion 5b of the engaging concave tool 5 strongly crimps the wedge portion 6b of the engaging convex tool 6 due to the filling pressure, so that the upper block body H does not fall over and is pulled out. Be blocked. The action is concrete 1
It is further increased with the consolidation of 8. (4) The blocks H are further stacked on the upper stage, and the filling concrete 18 is poured in the same manner as in (3) to construct the wall. In the above process, it is possible to prevent the blocks H from being piled up in the upward direction, to prevent them from collapsing, and to collectively pour the filled concrete 18 thereafter. The wall constructed in this way is filled with concrete 18
By solidifying, the wedge portion 6b of the engaging projection 6 is firmly restrained via the crimping portion 5b of the engaging recess 5 and exerts a great resistance force against falling. This restraint force is exerted not only on the individual block bodies H but also on the entire wall body. Therefore, in the construction of a wall body using this block body, the same strength as that of a conventional concrete block wall body with reinforcing reinforcing bars can be obtained without using reinforcing reinforcing bars, so that it is possible to eliminate the time required to purchase and purchase reinforcing reinforcing bars. It has an advantage that construction efficiency can be improved.

The same applies to the attachment of the engaging projection 6. In the above embodiments, the engaging recesses 5, 5A, 5B, 5C do not have a restraining action by themselves, but the filling action, that is, the filling concrete, exerts a restraining action.

(Third Embodiment) FIGS. 9 and 10 show still another embodiment of the construction block body of the present invention. The reference numerals in the figure correspond to those in the previous embodiment. This embodiment is mainly applied to retaining walls. FIG. 9 shows the connecting member. In the connecting member 2E, the abdominal plate 3 and the dovetail member 4 are the same as those in the first embodiment, but the engaging concave tool 5E and the engaging convex tool 6E.
The engaging member made of, especially the engaging recess 5E is characterized. In the connecting member 2E, the engaging recess 5E and the engaging protrusion 6E are connected by the flange plate 25. The flange plate 25 is interposed between the abdominal plate 3 and the dovetail member 4, and also functions as an interposing member that fixes both members. Engagement recess 5E
Has a substantially rectangular tubular shape that opens up and down, and the opening area is narrowed downward. That is, the engaging recess 5E is composed of a rear wall 26, a side wall 27, and a front wall 28. The rear wall 26 and the side wall 27 are formed thick, and the rear wall 26 also serves as the flange plate 25, and the side wall 27 is downward. The width gradually decreases to form a trapezoid. The front wall 28 is formed thin and inclines downward toward the rear wall 26. At the opening of the engaging recess 5E, the length a is equal to the engaging protrusion 6E.

The engaging projection 6E pushes the front wall 28 of the engaging recess 5E into the front surface of the engaging recess 6E when it is inserted into the engaging projection 6E. The lower side of 28 engages and resists the pulling force. As a result, the connecting member 2E has pull-out resistance by itself. Further, when the binding material 30 is filled in the engaging recesses 5E,
The pull-out resistance further increases (see FIG. 9 (b)). FIG.
(c) shows another mode of the engaging recess 5E. The front wall 28 of the engaging recess 5E is not inclined and is formed thin so as to have flexibility, and the front wall 2 is inserted when the engaging protrusion 6E is inserted.
8 is pushed out by its flexibility and allows easy insertion. After the engagement projection 6E is inserted, the original state is restored and the pull-out of the engagement projection 6E is resisted. In these aspects, the opening of the engaging recess 5E does not necessarily have to be a square tube shape, but may have another shape, for example, an arc shape between the side wall and the front wall. In this case, the wedge portion of the engaging projection 6E also has an arc cross section.

The engaging concave tool 5E and the engaging convex tool 6E are fixedly provided inside the reinforcing plate 7A. The connecting beam 8 fixedly connects the dovetail member 4 and the reinforcing plate 7 as an integral unit, but a bending type connecting beam 8A can be used instead of this mode. In the bending type connecting beam 8A, a beam 37 extending from the dovetail member 4 and a beam 38 extending from the reinforcing plate 7 are pin-coupled 40 by an intermediate beam 39. Thereby, the angle formed by the side plate 1 and the reinforcing plate 7 can be freely changed. 10B and 10C show still another mode of the connecting beam. The connecting beam 8B includes a beam 37 extending from the dovetail member 4 and a beam 38 extending from the reinforcing plate 7 via two intermediate beams 41 and 42, and these beams 37 and 3 are provided.
Pins 45 are provided in pin holes 43 that are provided in a large number in 8, 41, 42.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an engaging member for a building block according to the present invention will be described with reference to the drawings. 1 to 3
Indicates a building block body which is mainly applied to walls or walls. That is, FIG. 1 shows the entire block body, and FIGS. 2 and 3 show members used in the block body. The block bodies H are arranged facing each other.
It includes one side plate 1 and a connecting member 2 connecting the side plates 1. The detailed configuration of each member will be described below. The side plate 1 is made of an appropriate hard material such as concrete, tile, or synthetic resin, has a predetermined wall thickness, and has a rectangular shape.
Reference numeral 10 is a surface of the side plate 1, and the surface 10 is subjected to a makeup process. 11 is the back surface. Steps 12 are formed on the upper and lower side surfaces of the side surface plate 1 to engage with the other side surface 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 vertically provided along the width direction at predetermined intervals. The connecting member 2 includes a flat plate-shaped abdominal plate 3, vertical strip members fixed to both sides of the abdominal plate 3, that is, dovetail members 4, and engaging recesses 5 fixed to the upper part of the abdominal plate 3. The engaging projection 6 fixed to the lower part of the abdominal plate 3. More specifically, the abdominal plate 3 has a predetermined rigidity due to a predetermined thickness, and an opening 15 is formed in the center thereof. Abdominal plate 3
The width of the side plates 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 is composed of a base portion 5a and a crimp portion 5b,
It is composed entirely of elastic material. The base portion 5a is fixed to the abdominal plate 3 and the shelf plate 16 stretched from the abdominal plate 3. The engaging projection comprises a base portion 6a and a wedge portion 6b. Base 6a
Is fixed to the abdominal plate 3 and has rigidity. Then
The side plate 1 and the connecting member 2 are assembled as shown in FIG.
A unit block body H is formed. That is, the dovetail member 4 of the connecting member 2 is fitted into the dovetail groove 13 of the side surface 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 are self-supporting and maintain a required rigidity. FIG. 4 shows a state in which the block bodies H are vertically stacked. That is, each block body H is placed in the same phase state in the vertical direction, and when the upper block H is placed with respect to the lower block H, the wedge portion 6b of the engaging projection 6 is The crimp portion 5b of the engaging recess 5 is pushed and expanded to be fitted, and thereafter,
The crimping portion 5b of the engaging concave tool 5 is crimped to the engaging convex tool 6 by its elasticity. In this state, when concrete (this is referred to as filling concrete) is placed in the hollow portion of the block body H, the crimping portion 5b of the engaging recess 5 is restrained by the filling concrete, and thus the engagement is performed. The protrusion 6 is prevented from coming out.

An example of a method of constructing a wall body using the block body H will be described below in accordance with a construction procedure. (1) The foundation concrete B is placed at the planned construction position of the wall body, and the connecting reinforcing bars 17 are embedded along the center line of the wall body so as to project onto the upper surface of the foundation concrete B. In this state, the lower end surface of the side plate 1 is made into a flat fence, and the block body H (which is referred to as a foundation block body) without the engaging projection 6 is constructed such that the connecting rebar 17 is held in the hollow portion of the foundation concrete B. Is placed on the upper surface of the block body, and a plurality of these block bodies H are arranged in the horizontal direction. At this time, since the side surfaces of the block bodies H are the step portions 12, they are fitted into each other and arranged closely. (2) Next, the second-stage block body H is placed on the basic block body H with the same phase. At this time, the positions of the engaging concave tool 5 and the engaging convex tool 6 in the upper and lower block bodies H are on the same vertical line, and therefore, as described above, the engaging convex tool 6 of the upper block body H is in the lower part. It fits in the engaging recess 5 of the block body H. The upper and lower block bodies H are also aligned by the step portion 12. (3) Then, the filling concrete 18 is filled between the block bodies H of the first stage and the second stage. The filling of the filling concrete 18 is performed up to the middle of the upper block body H. When the filling concrete 18 is filled, the crimping portion 5b of the engaging concave tool 5 strongly crimps the wedge portion 6b of the engaging convex tool 6 due to the filling pressure, so that the upper block body H does not fall over and is pulled out. Be blocked. The action is concrete 1
It is further increased with the consolidation of 8. (4) The blocks H are further stacked on the upper stage, and the filling concrete 18 is poured in the same manner as in (3) to construct the wall. In the above process, it is possible to prevent the blocks H from being piled up in the upward direction, to prevent them from collapsing, and to collectively pour the filled concrete 18 thereafter. The wall constructed in this way is filled with concrete 18
By solidifying, the wedge portion 6b of the engaging projection 6 is firmly restrained via the crimping portion 5b of the engaging recess 5 and exerts a great resistance force against falling. This restraint force is exerted not only on the individual block bodies H but also on the entire wall body. Therefore, in the construction of a wall body using this block body, the same strength as that of a conventional concrete block wall body with reinforcing reinforcing bars can be obtained without using reinforcing reinforcing bars, so that it is possible to eliminate the time required to purchase and purchase reinforcing reinforcing bars. It has an advantage that construction efficiency can be improved.

FIG. 5 shows another mode of the connecting member. In this connecting member 2A, an engaging concave tool 5A and an engaging convex tool 6A along the longitudinal direction of the abdominal plate 3 are attached to the upper and lower parts of the abdominal plate 3. The engagement recesses 5A are provided with the crimp portions 5b facing each other, and the wedge portions 6b of the engagement projections 6 are elastically inserted between the opposing crimp portions 5b. FIG. 6 shows still another mode of the connecting member. In this connecting member 2B,
The abdominal plate 3A has flexibility, and flange plates 20 are fixed to both ends of the abdominal plate 3A instead of the dovetail members. More specifically, a flexible plate 21 having a curvature is interposed in the center of the abdominal plate 3A. Further, at the lower end of the flange plate 20,
The engaging projection 6 that fits into the engaging recess 5 is fixed. This connecting member 2B is a normal lightweight concrete block body J
It is used by interposing it in the hollow portion K of. The flange plate 20 of the connecting member 2B is pressed and fixed to the inner wall of the block body J, and after the block bodies J are assembled with each other, the filling concrete is poured to construct the wall body.

7 and 8 show another embodiment of the building block body. In the figure, the same reference numerals are given to the same members as the previous ones. In this block body H1, the engaging concave tool 5C and the engaging convex tool 6C of the connecting member 2C are provided.
And are arranged toward the side of the block body H1. That is, one coupling member 2C has one end of the flange plate 21 fixedly abutted against the abdominal plate 3 along the side plate 1, and the other end of the flange plate 21 has a base portion 5a and a crimp portion 5b. The engaging recess 5C made of
It is fixed via a. Also, the other connecting member 2
A flange plate 22 similar to the engaging recess 5c is fixed to the abdominal plate 3 at C ', and the flange plate 22 is engaged with the crimp portion 5b of the engaging recess 5C. The protrusion 6C is fixed. The heights of the engaging concave tool 5C and the engaging convex tool 6C may be smaller than the height of the side plate 1, but are normally about 1/2 to 1/3, and at that time, they are arranged at the same position. Of course. Further, it is also possible to adopt a mode in which a plurality of elements are arranged in the vertical direction. Then, these block bodies H
When 1s are arranged in the lateral direction, the engaging concave tool 5C and the engaging convex tool 6C between the adjacent block bodies H1 are fitted to each other, and then,
The engaging portion is constrained by the filling concrete poured into these hollow portions to form an integral wall body. In addition, this aspect is effective for a block body in which the height of the block body H1 is large. FIG. 8 shows another block body H2. In this block body H2, a dovetail-shaped protrusion 13A is formed so as to protrude from the wall surface of the side plate 1, and a dovetail groove member 4A fitted to the protrusion 13A is provided at both ends of the abdominal plate 3 in the connecting member 2D. While being fixed, the connecting member 2D is laterally integrated by the intermediate flange plate 23. Further, as shown by a broken line in FIG. 8, the engaging recesses 5 and the engaging protrusions 6 can be attached to the upper and lower ends of the flange plate 23 to fix the upper and lower block bodies H2. The same applies to the attachment of the engagement recess 5 and the engagement protrusion 6 to the flange plates 21 and 22 in FIG. 7. In the above embodiment, the engaging recesses 5, 5A, 5B, 5C have no restraining action by themselves, but the filling action, that is, the filling concrete, exerts the restraining action.

FIG. 9 and FIG. 10 show still another embodiment of the building block body. The reference numerals in the figure conform to those of the block body of the previous embodiment. This is mainly applied to retaining walls. FIG. 9 shows the connecting member. This connecting member 2E
Although the abdominal plate 3 and the dovetail member 4 conform to the above-mentioned aspect, the engaging member formed by the engaging concave tool 5E and the engaging convex tool 6E, particularly the engaging concave tool 5E, is characterized. In the connecting member 2E, the engaging recess 5E and the engaging protrusion 6E are connected by the flange plate 25. The flange plate 25 is interposed between the abdominal plate 3 and the dovetail member 4, and also functions as an interposing member that fixes both members. The engaging recess 5E is a substantially rectangular tubular body that opens vertically, and the opening area is narrowed downward. That is, the engagement recess 5E includes the rear wall 26, the side wall 27,
Although the front wall 28 is formed, the rear wall 26 and the side wall 27 are formed thick, and the rear wall 26 also serves as the flange plate 25.
The side wall 27 has a trapezoidal shape with its width gradually decreasing as it goes downward.
The front wall 28 is formed thin and inclines downward toward the rear wall 26. In the opening of the engaging concave tool 5E, its length a is larger than the width d of the engaging convex tool 6E, and the upper width b is sufficiently larger than the maximum thickness e of the engaging convex tool 6E. Has a width c slightly smaller than e. As a result, the front wall 28 has some elasticity. Thus, when the engaging projection 6E is fitted into the engaging recess 5E, the engaging projection 6E
E pushes in the front wall 28 of the engaging concave tool 5E and enters, and with respect to the pulling force, the uneven surface of the upper surface of the wedge portion 6b of the engaging convex tool 6E engages with the lower side of the front wall 28, and Resist pulling force. As a result, the connecting member 2E has pull-out resistance by itself. Furthermore, when the binding material 30 is filled in the engaging recesses 5E, the pullout resistance further increases (see FIG. 9B). FIG. 9 (c) shows another mode of the engaging recess 5E. The front wall 28 of the engagement recess 5E is not inclined,
By being formed thin, it has flexibility and the engaging projection 6
Upon insertion of E, the front wall 28 is spread out due to its flexibility, allowing easy insertion. After the engagement projection 6E is inserted, the original state is restored and the pull-out of the engagement projection 6E is resisted.
In these aspects, the opening of the engaging recess 5E does not necessarily have to be a square tube shape, but may have another shape, for example, an arc shape between the side wall and the front wall. In this case, the wedge portion of the engaging projection 6E also has an arc cross section.

FIG. 10 shows a block to which this connecting member 2E is applied. In FIG. 10 (a), this block H3
Is composed of one side plate 1 and a connecting member 2F having a reinforcing beam 7 on the other side connected to the side plate 1 and a connecting beam 8 in place of the abdominal plate. More specifically, the connecting member 2
F is a dovetail member 4 on the side fitted to the side plate 1.
And an engaging concave tool 5E and an engaging convex tool 6E which are fixed above and below the dovetail member 4. On the other hand, on the opposite side of the side plate 1, the reinforcing plate 7 is composed of a horizontal beam 32 and a vertical beam 33, and a wire mesh (mesh) is provided between the horizontal beam 32 and the vertical beam 33.
35 is fixed. The engaging concave tool 5E and the engaging convex tool 6E are fixedly provided inside the reinforcing plate 7A. The connecting beam 8 fixedly connects the dovetail member 4 and the reinforcing plate 7 as an integral unit, but a bending type connecting beam 8A can be used instead of this mode. In the bending type connecting beam 8A, a beam 37 extending from the dovetail member 4 and a beam 38 extending from the reinforcing plate 7 are pin-coupled 40 by an intermediate beam 39. Thereby, the angle formed by the side plate 1 and the reinforcing plate 7 can be freely changed. 10B and 10C show still another mode of the connecting beam. The connecting beam 8B includes a beam 37 extending from the dovetail member 4 and a beam 38 extending from the reinforcing plate 7 via two intermediate beams 41, 42, and these beams 37, 38, 41, 4 are provided.
The length of the connecting beam 8B can be expanded and contracted by inserting the pin 45 into a large number of pin holes 43 formed in 2. Thus, the distance between the side plate 1 and the flange plate 7A can be made variable, and the angle between them can be made variable.

FIG. 11 shows an example of application of this block body to a retaining wall. FIG. 11 (a) shows a retaining wall using a block body H3 having a fixed connection beam. In the figure, E is the ground, and the ground E is dug down to lay the foundation stone 50 and the concrete footing 51 is placed on it. After that, the block bodies H3 are sequentially stacked, and when the number of stages becomes appropriate, the filling concrete 52 is poured. Along with this, the back-filled slabs 53 are filled in the back surface of the retaining wall. Hereinafter, the block bodies H3 are sequentially stacked to construct a retaining wall. In the retaining wall of this aspect, the width W of each block H3 is constant, and the sectional change of the retaining wall is made by placing concrete 52 on the back surface of the reinforcing plate 7 or adjusting the length of the connecting beam 8. . FIG. 11 (b) shows a retaining wall using a block body H2 having a telescopic connecting beam 8B. Also in this retaining wall, the foundation stone 50 and the concrete footing 51 are placed on the ground E, and the block bodies H3 are sequentially stacked thereon. 55 is leveling concrete. In the block body H3 in the lowermost stage, the connecting beam 8B has the maximum length, and the reinforcing plate 7 is inclined so that the width thereof decreases as it goes upward. Next, the block body H3 of the second stage in which the length of the connecting beam 8B is reduced is placed on this, and the engaging concave tool and the convex tool are engaged with each other, and in this state, the filling concrete 52 is poured. It Further, in the block body H3 in the upper stage, the length of the connecting beam 8B is reduced, and similarly, a retaining wall is constructed. 12 and 13 show another mode. The engagement recess 5F shown in FIGS. 12 (a) and 12 (b) is formed by pin engagement. That is, the front wall portion 28A has a flange portion 60 at both ends thereof along the side wall 27, and the side wall 27 and the flange portion 60 are pivotally attached to each other by the pin 61, whereby the front wall portion 28A is fixed to the pin 6.
It becomes possible to rotate around 1. Further, a hinge spring 62 is provided on one of the pins 61 at both ends thereof to form the rear wall 26 and the front wall portion 28A.
Abutting against the front wall 28A.
After the engaging projection is inserted, the state becomes a broken line, but when the engaging projection is inserted, it returns to the normal position. In the connecting member 2G shown in FIG. 13, the dovetail members 4 are fixed to each other via a box-shaped engaging concave tool 5G on the upper side and an engaging convex tool 6G on the lower side. Further, in the embodiment of FIG. 10, one side plate 1 and an engagement recess 5 </ b> E and an engagement protrusion 6 </ b> E fixed above and below the dovetail member 4 that engages with the dovetail groove 13 of the side plate 1. Block body (this is called a side plate block body). Then, these block bodies are vertically and laterally engaged with each other to form a wall body (for example, a formwork substitute wall).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an engaging member for a building block according to the present invention will be described with reference to the drawings. 1 to 3
Indicates a building block body which is mainly applied to walls or walls. That is, FIG. 1 shows the entire block body, and FIGS. 2 and 3 show members used in the block body. The block bodies H are arranged facing each other.
It includes one side plate 1 and a connecting member 2 connecting the side plates 1. The detailed configuration of each member will be described below. The side plate 1 is made of an appropriate hard material such as concrete, tile, or synthetic resin, has a predetermined wall thickness, and has a rectangular shape.
Reference numeral 10 is a surface of the side plate 1, and the surface 10 is subjected to a makeup process. 11 is the back surface. Steps 12 are formed on the upper and lower side surfaces of the side surface plate 1 to engage with the other side surface 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 vertically provided along the width direction at predetermined intervals. The connecting member 2 includes a flat plate-shaped abdominal plate 3, vertical strip members fixed to both sides of the abdominal plate 3, that is, dovetail members 4, and engaging recesses 5 fixed to the upper part of the abdominal plate 3. The engaging projection 6 fixed to the lower part of the abdominal plate 3. More specifically, the abdominal plate 3 has a predetermined rigidity due to a predetermined thickness, and an opening 15 is formed in the center thereof. Abdominal plate 3
The width of the side plates 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 is composed of a base portion 5a and a crimp portion 5b,
It is composed entirely of elastic material. The base portion 5a is fixed to the abdominal plate 3 and the shelf plate 16 stretched from the abdominal plate 3. The engaging projection comprises a base portion 6a and a wedge portion 6b. Base 6a
Is fixed to the abdominal plate 3 and has rigidity. Then
The side plate 1 and the connecting member 2 are assembled as shown in FIG.
A unit block body H is formed. That is, the dovetail member 4 of the connecting member 2 is fitted into the dovetail groove 13 of the side surface 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 are self-supporting and maintain a required rigidity. FIG. 4 shows a state in which the block bodies H are vertically stacked. That is, each block body H is placed in the same phase state in the vertical direction, and when the upper block H is placed with respect to the lower block H, the wedge portion 6b of the engaging projection 6 is The crimp portion 5b of the engaging recess 5 is pushed and expanded to be fitted, and thereafter,
The crimping portion 5b of the engaging concave tool 5 is crimped to the engaging convex tool 6 by its elasticity. In this state, when concrete (this is referred to as filling concrete) is placed in the hollow portion of the block body H, the crimping portion 5b of the engaging recess 5 is restrained by the filling concrete, and thus the engagement is performed. The protrusion 6 is prevented from coming out.

An example of a method of constructing a wall body using the block body H will be described below in accordance with a construction procedure. (1) The basic concrete B is placed at the planned construction position of the wall body, and the connecting reinforcing bars 17 are embedded along the center line of the wall body so as to project onto the upper surface of the basic concrete B.
In this state, the lower end surface of the side surface plate 1 is made into a flat fence and the block body H (which is referred to as a basic block body) having no engaging projection 6 is held in the hollow portion so as to hold the connecting rebar 17.
It is placed on the upper surface of the basic concrete B, and a plurality of these block bodies H are arranged side by side in the lateral direction. At this time, since the side surfaces of the block bodies H are the step portions 12, they are fitted into each other and arranged closely. (2) Next, the block body H of the second stage is placed on the basic block body H with the same phase. At this time, the positions of the engaging concave tool 5 and the engaging convex tool 6 in the upper and lower block bodies H are on the same vertical line, and therefore, as described above, the engaging convex tool 6 of the upper block body H is in the lower part. It fits in the engaging recess 5 of the block body H. The upper and lower block bodies H are also aligned by the step portion 12. (3) Then, the block bodies H of the first and second stages
Filled with filling concrete 18 between them. The filling of the filling concrete 18 is performed up to the middle of the upper block body H. When the filling concrete 18 is filled, the crimping portion 5b of the engaging concave tool 5 strongly crimps the wedge portion 6b of the engaging convex tool 6 by the filling pressure, and the upper block body H is formed.
Falling out and withdrawal are prevented. The action is further increased with the solidification of the concrete 18. (4) Further, the block bodies H are stacked on the upper stage, and the filled concrete 18 is poured in the same manner as in (3) to construct the wall body. In the above process, it is possible to prevent the blocks H from being piled up in the upward direction, to prevent them from collapsing, and to collectively pour the filled concrete 18 thereafter. The wall constructed in this way is filled with concrete 1

This restraint force is exerted not only on the individual block bodies H but also on the entire wall body. Therefore, in the construction of a wall body using this block body, the same strength as that of a conventional concrete block wall body with reinforcing reinforcing bars can be obtained without using reinforcing reinforcing bars, so that it is possible to eliminate the time required to purchase and purchase reinforcing reinforcing bars. It is possible,
It has the advantage of improving the construction efficiency.

And are arranged toward the side of the block body H1. That is, one coupling member 2C has one end of the flange plate 21 fixedly abutted against the abdominal plate 3 along the side plate 1, and the other end of the flange plate 21 has a base portion 5a and a crimp portion 5b. The engaging recess 5C made of
It is fixed via a. Also, the other connecting member 2
A flange plate 22 similar to the engaging recess 5c is fixed to the abdominal plate 3 at C ', and the flange plate 22 is engaged with the crimp portion 5b of the engaging recess 5C. The protrusion 6C is fixed. The heights of the engaging concave tool 5C and the engaging convex tool 6C may be smaller than the height of the side plate 1, but are normally about 1/2 to 1/3, and at that time, they are arranged at the same position. Of course. Further, it is also possible to adopt a mode in which a plurality of elements are arranged in the vertical direction. Then, these block bodies H
When 1s are arranged in the lateral direction, the engaging concave tool 5C and the engaging convex tool 6C between the adjacent block bodies H1 are fitted to each other, and then,
The engaging portion is constrained by the filling concrete poured into these hollow portions to form an integral wall body. In addition, this aspect is effective for a block body in which the height of the block body H1 is large. FIG. 8 shows another block body H2. In this block body H2, a dovetail-shaped protrusion 13A is formed so as to protrude from the wall surface of the side plate 1, and a dovetail groove member 4A fitted to the protrusion 13A is provided at both ends of the abdominal plate 3 in the connecting member 2D. While being fixed, the connecting member 2D is laterally integrated by the intermediate flange plate 23. Further, as shown by a broken line in FIG. 8, the engaging recesses 5 and the engaging protrusions 6 can be attached to the upper and lower ends of the flange plate 23 to fix the upper and lower block bodies H2. The same applies to the attachment of the engagement recess 5 and the engagement protrusion 6 to the flange plates 21 and 22 in FIG. 7. In the above embodiment, the engaging recesses 5, 5A, 5B, 5C have no restraining action by themselves, but the filling action, that is, the filling concrete, exerts the restraining action.

FIG. 9 and FIG. 10 show still another embodiment of the building block body. The reference numerals in the figure conform to those of the block body of the previous embodiment. This is mainly applied to retaining walls. FIG. 9 shows the connecting member. This connecting member 2E
Although the abdominal plate 3 and the dovetail member 4 conform to the above-mentioned aspect, the engaging member formed by the engaging concave tool 5E and the engaging convex tool 6E, particularly the engaging concave tool 5E, is characterized. In the connecting member 2E, the engaging recess 5E and the engaging protrusion 6E are connected by the flange plate 25. The flange plate 25 is interposed between the abdominal plate 3 and the dovetail member 4, and also functions as an interposing member that fixes both members. The engaging recess 5E is a substantially rectangular tubular body that opens vertically, and the opening area is narrowed downward. That is, the engagement recess 5E includes the rear wall 26, the side wall 27,
Although the front wall 28 is formed, the rear wall 26 and the side wall 27 are formed thick, and the rear wall 26 also serves as the flange plate 25.
The side wall 27 has a trapezoidal shape with its width gradually decreasing as it goes downward.
The front wall 28 is formed thin and inclines downward toward the rear wall 26. In the opening of the engaging concave tool 5E, its length a is larger than the width d of the engaging convex tool 6E, and the upper width b is sufficiently larger than the maximum thickness e of the engaging convex tool 6E. Has a width c slightly smaller than e. As a result, the front wall 28 has some elasticity. Thus, when the engaging projection 6E is fitted into the engaging recess 5E, the engaging projection 6E
E pushes in the front wall 28 of the engaging concave tool 5E and enters, and with respect to the pulling force, the uneven surface of the upper surface of the wedge portion 6b of the engaging convex tool 6E engages with the lower side of the front wall 28, and Resist pulling force. As a result, the connecting member 2E has pull-out resistance by itself. Furthermore, when the binding material 30 is filled in the engagement recesses 5E, the pullout resistance further increases (see FIG. 9B). FIG. 9C shows another mode of the engaging recess 5E. The front wall 28 of the engaging recess 5E is not inclined and is thin so that it has flexibility, and when inserting the engaging protrusion 6E, the front wall 28 is expanded by its flexibility. Allows easy insertion. After the engagement projection 6E is inserted, the original state is restored and the pull-out of the engagement projection 6E is resisted. In these aspects, the opening of the engaging recess 5E does not necessarily have to be a square tube shape, but may have another shape, for example, an arc shape between the side wall and the front wall. In this case, the wedge portion of the engaging projection 6E also has an arc cross section.

FIG. 10 shows a block to which this connecting member 2E is applied. In FIG. 10A, this block H3

35 is fixed. The engaging concave tool 5E and the engaging convex tool 6E are fixedly provided inside the reinforcing plate 7A. The connecting beam 8 fixedly connects the dovetail member 4 and the reinforcing plate 7 as an integral unit, but a bending type connecting beam 8A can be used instead of this mode. In the bending type connecting beam 8A, a beam 37 extending from the dovetail member 4 and a beam 38 extending from the reinforcing plate 7 are pin-coupled 40 by an intermediate beam 39. Thereby, the angle formed by the side plate 1 and the reinforcing plate 7 can be freely changed. 10B and 10C show another mode of the connecting beam. The connecting beam 8B includes a beam 37 extending from the dovetail member 4 and a beam 38 extending from the reinforcing plate 7 via two intermediate beams 41, 42, and these beams 37, 38, 4 are provided.
The length of the connecting beam 8B is made flexible by inserting the pins 45 into the pin holes 43 formed in a large number in the pins 1 and 42. Thus, the distance between the side plate 1 and the flange plate 7A can be made variable, and the angle between them can be made variable.
