Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block which is stacked and used in a plurality of upper and lower stages to construct various types of wall bodies such as retaining walls, greening walls and fish nests.

[0002]

2. Description of the Related Art In a masonry retaining wall that has been widely used as a retaining wall, the masonry material presses the backing material against each other to maintain its position. The point of action of the resultant force of body weight and earth pressure must be inside the wall front surface at an arbitrary height, and a line obtained by connecting the points of action of the resultant force at each height, that is, a force line. The shapes are classified into three types, A, B, and C, as shown in FIG.

In the type A, the line of force is located within the center 1/3 (middle third) of the cross section of the wall from the top to the foundation, so that it is the most stable wall, especially the center of the wall. Is aligned with the line of force, the most ideal wall is constructed from both aspects of stability and aesthetics.

In the type B, the lines of force of force are projected from the rear surface of the wall except for the top end and the vicinity of the foundation. Sufficient compaction is required.

In the type C, since the lower part of the force line protrudes from the front surface of the wall, there is a risk of the wall protruding and collapsing. Therefore, the retaining length of the retaining wall should be set longer or the inclination of the retaining wall should be increased. Need to be set loosely.

In a conventional concrete block provided as a masonry material that replaces Machichi stone, rubble stone, cobblestone, etc., the upper and lower surfaces of the blocks joined at the time of stacking are generally formed into flat surfaces. ..

Therefore, when the lower block is placed on the foundation concrete whose upper surface is inclined, and the lower surface of the upper block is joined to the upper surface of the lower block to stack the blocks in upper and lower stages, the front faces of the upper and lower blocks are Since the lines are aligned on a slanting straight line, and naturally the longitudinal centerline of the wall body is also a slanting straight line, it does not coincide with the force line that is a curve concave to the front side.

In the valley stacking block disclosed in Japanese Utility Model Laid-Open No. 58-69044, a positioning ridge is formed on one of the opposing side surfaces of the main body, and the other locating ridge is formed on the other opposing side surface of the main body during stacking. To form a positioning groove into which
The longitudinal section of the positioning ridge and the positioning groove in the front-rear direction has an arc shape.

However, in this knowledge block, the positioning ridges and the positioning grooves are provided only at the intermediate portions of the upper and lower joining end faces of the block, and the ridge lines forming the joints on the front side of the positioning ridges and the front side of the positioning grooves. Since the ridges are provided, the upper block is obstructed by the joint end when the positioning ridge is fitted into the positioning groove to the point where the ridge line portion is in considerable contact, and therefore the upper block is inclined and rotated toward the front side with respect to the lower block. It is completely impossible to do.

Thus, the positioning ridge and the positioning groove are
It is provided only to prevent the misalignment of the blocks by positioning the joints between adjacent blocks, and the positioning ridges and the positioning grooves make the upper blocks lower blocks after the blocks are stacked. On the other hand, it is not intended to be rotated to the front side in the vertical plane.

Therefore, also in this intelligent block, the front surfaces of the blocks in the upper and lower stages are aligned on an inclined straight line, and naturally, the longitudinal center line of the wall body is also an inclined straight line. It does not match the force line, which is a curve that is concave to the side.

As described above, in the conventional masonry wall body or block masonry wall body, the longitudinal centerline of the wall body cannot be matched with the force line that is a curve concave to the front side, and thus the wall body The slope of the wall is set gently to ensure stability, and the maximum allowable height of the wall is set relatively low.

However, if the slope of the wall is set to be gentle, the area occupied by the wall construction on the ground following the top or the ground following the foundation will increase, which poses a problem in effective use of land.

[0014]

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to stack the walls properly and easily so that the longitudinal centerline of the wall coincides with the force line of force, or most of them are sufficiently close to each other. It is an object of the present invention to provide a block for constructing a wall body that can efficiently perform the stacking work and the work for adjusting the arrangement angle because there are sufficiently stable clues.

The arrangement angle of each flat surface portion is set so that there is a play gap between the front flat surface portion 1a of the above and the front flat surface portion 1c of the joining convex portion 3.

[0018]

When the wall is constructed, the blocks 1 and 1 are stacked by fitting the projections 3 for joining of the upper block into the recesses 2 for joining of the lower block 1. After stacking one stage, slide the joining convex portion 3 of the upper block 1 onto the joining concave portion 2 of the lower block 1 so that the center of the upper block 1 coincides with the force line calculated in advance for the wall body to be constructed. While being in contact with each other, the upper block is rotated to the front side by a required angle in the vertical plane about the joining recess 2 of the lower block.

The maximum permissible limit of the rotation angle to the front side is that the flat surface portion 1b on the rear side of the concave portion for joining 2 and the convex portion for joining 3
When the flat surface portion 1d on the rear side is in substantial contact, the recessed portion 2 for joining
It is determined by the play gap that occurs between the front flat surface portion 1a and the front flat surface portion 1c of the joining convex portion 3.

Thereafter, by repeating the stacking and the adjustment of the arrangement angle, a large number of blocks from the lowermost block to the uppermost block fitted in the concrete foundation are sequentially stacked along the force lines. ..

If the wall to be constructed is a soil retaining wall, the back of the piled blocks 1 and 1 is filled with backfill material such as backfilling rubble and crushed gravel according to a conventional method, and Is backfilled and the required drainage pipe is installed.

In the case of the kneading, the joint mortar is filled in a space between the joining concave portion 2 of the lower block 1 and the joining convex portion 3 of the upper block 1 according to a conventional method, and backfilling is carried out behind the block stacking wall body. Concrete is poured, the back soil is backfilled, and the required drainage pipes are installed.
