DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block wall structure in which a plurality of blocks are formed adjacent to each other in a horizontal direction to form a row block group and the row block groups are vertically stacked in a plurality of stages. It is.

[0002]

2. Description of the Related Art A block wall structure of this type is used, for example, as a wall of a building or a block wall. In the conventional block wall structure, a block made of brick or the like is used as a single block for constructing the block wall. Concrete blocks are used.

[0005] FIG. 5 shows an example of a conventional block wall structure. In the conventional block wall Y, a block 101 having a rectangular parallelepiped shape such as a brick is used as the block unit 101. In the case of brick, the length is 20c
m, the width is about 10 cm, and the height is about 6 cm. In this conventional block wall structure, a predetermined number of rectangular parallelepiped blocks 101, 101,... Are installed adjacent to each other in the left-right lateral direction (in the direction of arrows AB) on the foundation concrete 6, and the lowermost row row block group After the second block 102 is formed, another block unit 101, 101,... Is sequentially stacked horizontally on the existing row block group 102 to form a second row block group 102. A predetermined number of row block groups 2, 2,... Are stacked to form a block wall Y having a predetermined size. A horizontal joint (mortar) 4 is interposed between the vertically adjacent blocks 101, 101, and a vertical joint (mortar) 5 is interposed between the left and right adjacent blocks 101, 101. The vertical and horizontal joints 4 and 5 are used to bond the upper and lower and left and right blocks to each other. In the conventional block wall structure shown in FIG. 5, each of the vertical block groups 103, 103,... Stacked in the vertical direction is in a state in which each of the rectangular parallelepiped blocks 101, 101,. (Without protruding). Also, in this type of block wall structure, there is a column block group 103
Each of the block blocks 101, 101,.
A horizontal reinforcing bar is interposed between
Some are reinforced with respect to the deformation acting force in the front-rear direction (the direction of the arrow CD) with respect to.

[0004]

In the conventional block wall structure shown in FIG. 5, a block 101 having a rectangular shape (each corner is at an angle of 90 °) in plan view is employed. And the row block group 10 of each stage
2, 102..., Each block alone 101, 10
1. The end faces in the longitudinal direction are perpendicular to the front-rear direction (arrow C-direction) with respect to the left-right direction (arrow AB direction) of the block wall Y.
It is simply bonded by the vertical joints 5 (mortar) in a posture facing (D direction) (particularly when a reinforcing horizontal reinforcing bar is not used). As described above, in a structure in which the blocks 101, 101 adjacent and joined in the left-right direction are simply bonded by the vertical joints 5, only the vertical block groups 103, 10
3 (or each block 10 adjacent to the left and right)
1, 101) is weakened. For example, when a large earthquake occurs, or when a car accidentally collides, the front-rear direction (arrow C)
When a deformation acting force (−D direction) is generated, the left and right vertical block groups 103 and 103 (or the left and right adjacent block units 101 and 101) are easily displaced at the vertical joint 5 and collapse. The risk increases. That is, the conventional block wall structure shown in FIG. 5 has a low strength against the deformation acting force in the front-rear direction. In addition, when a reinforcing steel bar is buried in the block wall, the strength against the deformation acting force is increased, but the cost is increased and the construction work of the block wall is complicated.

[0005] In this type of block wall, a horizontal joint (mortar) 4 is provided with a predetermined thickness (for example, about 3 to 5 mm) on the upper surface of the existing side block unit 101 when constructing the vertical block group 103 of each stage. After applying only another block 1
01 is stacked. By the way, FIG.
In the conventional example of FIG. 6, the upper and lower blocks 101, 101 are laminated in a state of being completely overlapped with each other.
As shown in FIG. 6, even if the thickness of the horizontal joints 4 is different from the horizontal joint thickness located on the left and right (in the example of FIG. 6, each block unit 101, 1 in the column block group 103 in the second column from the left end)
01 .. The thickness of the horizontal joint is thicker than the other parts), and the individual blocks can be stacked without any problem. In that case (when the thickness of the horizontal joint 4 is different)
, The horizontal joints 4, 4... Of the unit length (the length of one block unit) are not arranged in a straight line (a step is generated in the adjacent horizontal joints 4, 4 as shown in FIG. 6). . As described above, if a step occurs in each of the horizontal joints 4, 4,... Belonging to the same row, there is a problem that the appearance of the entire block wall is deteriorated. Also, each such row block group 102, 1
02 leveling work (that is, work with uniform thickness of each horizontal joint 4, 4,...) Requires considerable skill, and the number of technicians (blockers) of this kind is decreasing in recent years. Then
At present, there is a shortage of skilled workers.

The present invention has been made in view of the above-described problems of the conventional block wall structure, and for example, allows the block wall to be firmly constructed by the engagement force between the blocks alone without using a reinforcing bar. It is another object of the present invention to provide a block wall structure capable of easily and surely performing a leveling operation of each row block group.

[0007]

The block wall structure of the present invention has the following structure as means for solving the above-mentioned problems.

That is, the present invention relates to a block wall structure comprising a plurality of blocks arranged one by one adjacently in a horizontal direction to form a row block group, and the row block group is vertically stacked in a plurality of stages. Each block has a trapezoidal shape in plan view, in which the front and rear sides facing each other are short side surfaces having a short left and right length and long side surfaces having a long left and right length. The side surface and the long side surface are arranged so as to be sequentially adjacent to each other on the same surface side, and further, each row block group is configured such that the short side surface and the long side surface of each block unit at the position where the blocks overlap vertically Are arranged so as to be adjacent to each other alternately in the vertical direction.

That is, in the present invention, a plurality of trapezoidal blocks in a plan view are formed on the same side surface of a block wall, and short side surfaces and long side surfaces of the block units are alternately sequentially arranged in the left-right direction and the up-down direction. It is constructed by assembling it in a state where it appears.

In the present invention, a block made of, for example, a brick or a concrete block can be used. In addition, a large number of blocks each having the same shape formed in a trapezoidal shape in plan view are used. The shape of the block alone in a plan view is preferably an isosceles trapezoid, but an unequal legs trapezoid can also be used. When a brick is used as a single block, for example, the trapezoidal trapezoid in plan view has a short side surface of 10 cm, a long side surface of 20 cm, a width of 10 cm, and a thickness of 6 cm.
A size of about cm can be used. In this case, each corner of the long side surface and the inclined side surface on each side becomes sharp at an angle of about 64 °. Each corner between the long side surface and the inclined side surface on each side is referred to as an acute corner in the following description. When a block made of a concrete block is used, the block is formed into an appropriate size depending on the application. In this case, the block is also formed into a trapezoid in plan view.

Each block is arranged in a predetermined number in the left and right direction, and a suitable number of layers are stacked up and down to form a block wall. Vertical joints and horizontal joints made of mortar are interposed.

[0012]

In the block wall structure of the present invention, a plurality of blocks each having a trapezoidal shape in a plan view are formed such that short side surfaces and long side surfaces alternately appear on the same side surface of the block wall alternately in the left, right, up and down directions. Therefore, in each row block group, the butted side surfaces of the blocks adjacent to each other overlap each other in a front view. Therefore, the superposed portion of each block unit adjacent to the left and right (this superposed portion occurs on both the left and right sides of one block unit) allows each block unit to reinforce each other against the deformation acting force from the front-back direction. Become.

Further, in the block wall structure of the present invention, in each of the row block groups vertically adjacent to each other, each block alone is composed of one located immediately above and below the other row block group and two located on both left and right sides thereof. It overlaps vertically over three blocks alone. That is, one block alone (this is referred to as a reference block alone)
In the central part in plan view, the blocks located directly above and below overlap with the large area vertically, and the left and right acute corners of the reference block are located on the left and right of the blocks located immediately above and below. In the vicinity of one of the acute corners. Therefore, the horizontal joints corresponding to the same height in each column block group surely continue at the same height position. This means that when stacking the following individual blocks on the existing row block group, the lower surface of
The result is that the upper surface of the block unit located immediately below and the upper surface of each block unit positioned diagonally below the left and right are no longer located below each, and if the unit lengths are located at the same height Even if there is some variation in the thickness of the horizontal joint, there is an effect that the horizontal alignment of the stacked side row blocks can be reliably performed.

Further, in the block wall structure of the present invention, as described above, since a part of each block unit of each column block group located adjacent to the left and right is vertically overlapped with each other, each column The vertical displacement of the block group does not occur.

[0015]

According to the block wall structure of the present invention, a plurality of trapezoidal blocks in plan view are used, and the short side and long side of each block are adjacent to each other alternately in the left-right direction in the same plane. Each row block group is arranged in such a manner that the butted ends of the blocks adjacent to each other in each row block group overlap each other in a front view. Therefore, the overlapping portions of the blocks adjacent to each other on the left and right sides in a front view reinforce each other, and there is an effect that the strength is increased with respect to the deformation acting force on the block wall from the front-rear direction.

In the block wall structure according to the present invention, in each of the vertically adjacent row block groups, the short side surface and the long side surface of each block unit at the vertically overlapping position are alternately adjacent to each other in the vertical direction. It is arranged so that
One block unit is vertically overlapped over a total of three block units in the row block group adjacent above or below. Therefore, the horizontal joints between the vertically adjacent row block groups are surely located at the same height, the appearance of the block wall is improved, and each block alone is stacked on the existing side row block group. There is an effect that the stacked side row block group can be leveled out reliably and easily without requiring any skill at the time of work.

Further, in the block wall structure of the present invention, since a part of each block unit of each column block group adjacent to the left and right is vertically overlapped with each other, the vertical direction of each column block group is This eliminates the occurrence of positional deviation, and has the effect of providing a stronger block wall.
