Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a retaining wall block used when constructing a retaining wall, and is particularly installed in a corner portion of the retaining wall.

(Prior Art) Conventionally, a corner portion of a retaining wall has a specific corner angle corresponding to the location, and a retaining wall block arranged at this corner portion has a bending angle corresponding to the corner angle. The bent plate-shaped block that has is used.

In addition to this, a method of arranging two block plates respectively corresponding to the corner surfaces of the corners to construct the corners is also performed.

(Problems to be solved by the invention) However, when using bent plate-shaped blocks, it is necessary to manufacture bent plate-shaped blocks having different bending angles for different corner angles and prepare them separately. Not only the workability is poor, but also the manufacturing cost is increased.

Moreover, when two block plates are used, the block plates are fixedly installed on the ground, respectively, and the work is troublesome, and it is not easy to accurately adjust the crossing angle of each other. There is a problem.

The present invention has a basic purpose to solve the above-mentioned problems, and it is possible to install it even at corners with different angles by adapting the angle by simple adjustment and dramatically improving work efficiency. It provides a wall block.

(Means for Solving the Problem) A retaining wall block of the present invention is a retaining wall block arranged at a corner portion, and is constituted by two block members each having a wall surface corresponding to a corner surface. Since the block members are connected to each other with variable corner angles, the above problems have been solved.

That is, the present invention is a retaining wall block arranged at a corner portion, which is composed of two block members each having a wall surface corresponding to the corner surface, and a projecting portion is provided on a part of the connecting side end surface of one block member. A projecting portion that is continuously provided and is fitted to a projecting portion of the one block member is continuously provided to a connection side end surface of the other block member, and both projecting portions are connected via a vertical axis, and the two The block member is a retaining wall block characterized in that it is connected by the vertical axis so that the corner angle is variable.

The block member is usually plate-shaped, but it is not necessarily limited to this, and the point is that the wall surface constitutes one corner surface.

As a method of connecting the block members with variable corner angles, for example, a common shaft rod is used, or means for fitting the two members in a concavo-convex manner is used so that the block members can rotate on the vertical axis.

(Operation) That is, according to the present invention, since the two block members are connected so that the corner angle can be changed, the corner angle can be appropriately adjusted, for example, at the site to surely and easily match the corner angle of the retaining wall to be constructed.

This angle adjustment can be performed within a range in which the block members can rotate, and it is possible to easily cope with various corner angles.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.

The retaining wall block 1 is composed of a block member 2 and a block member 3, and one ends of the retaining wall block 1 are rotatably fixed to each other.

Explaining in detail below, the block member 2 and the block member 3 are respectively plate-shaped vertical walls 21, 31 and vertical walls 21, 31.
Bottom plates 22 and 32 that are orthogonal to each other at the lower end of the. The vertical wall 2
Ribs 23 and 33 are provided inside the intersecting portions of the bottom plates 22 and 32 and the bottom plates 1 and 31, respectively. The bottom plate 22 and the bottom plate 32 have a substantially right-angled triangular shape, and their hypotenuses 24 and 34 are opposed to each other on the axial stop side.

Further, at the lower part of the end surface of the block member 2 on the shaft stop side, a protruding portion 4 formed of a semi-cylindrical shape reaching from the lower end to about 1/3 the height of the vertical wall is provided. A rebar is embedded as a rotating shaft 5 in the upper end portion of the projecting portion 4, and the upper portion thereof projects from the upper end surface of the projecting portion 4.

On the other hand, above the shaft stop side end surface of the block member 3, a semi-cylindrical protrusion 6 reaching from the upper end to a height position of about 2/3 of the vertical wall.
Is provided, and a shaft hole 7 into which the rotary shaft 5 is loosely fitted is formed in the lower end surface thereof.

In this retaining wall block 1, the block member 2 and the block member 3 are connected by stacking the above-mentioned protruding portion 4 and the protruding portion 6 vertically and fitting the rotary shaft 5 into the shaft hole 7. There is.

In this state, the block member 2 and the block member 3 can rotate relative to each other with the rotation axis 5 as the vertical axis. Then, as the minimum corner angle, the oblique sides 24, 34 of the bottom plates 22, 32 are in contact with each other, and an angle at which the vertical wall 21 and the vertical wall 31 are orthogonal to each other is obtained,
As the maximum corner angle, for example, the vertical wall 21 and the vertical wall 31 are
The angle of intersection at 180 degrees is obtained.

The method of using the retaining wall block 1 will be described below.

That is, the retaining wall block 1 is placed at the place where the retaining wall is constructed, and the block members 2, 3 are aligned with the corner angles of the retaining wall.
Rotate and adapt its intersection angle to the corner angle.

Note that mounting holes 8 are formed near the hypotenuse of the tip portion of the bottom plate.

Mounting pins 9 and 9 are inserted into the mounting holes 8 and 8, respectively, and a mounting bracket 11 having a long flat plate shape and a long hole 10 formed along the outer shape at the center is fastened and fixed.

In this state, a corner retaining wall adapted to the corner angle can be easily obtained.

Further, when the corner angle is different from the angle adjusted above at different installation locations, the block member 2 and the block member 3 are rotated with respect to each other to change the crossing angle so that the corner angle can be easily changed. Can be adapted to.

In the above embodiment, the crossing angle between the block members was limited to a minimum of 90 degrees depending on the shape of the bottom plate, but a smaller crossing angle can be set depending on the shape of the bottom plate.

After installation / fixing, a small gap is created between the protruding portion of one vertical wall and the end face of the other vertical wall. In this gap, if desired, a filler such as concrete or mortar is filled.
Pack 12 Since this gap is formed between the arcuate surface of the projecting portion and the plane of the vertical wall, it is relatively small and the work of filling the filling material 12 can be easily performed. If the end face of the vertical wall facing the protrusion is a concave arc surface, the gap can be made even smaller.

(Effect of the Invention) As described above, according to the retaining wall block of the present invention, the retaining wall block arranged at the corner is
It is composed of two block members each having a wall surface corresponding to one corner surface, and these two block members are connected to each other through the protrusions at the end portions on the connection side and are connected via the vertical axis to make the corner angle variable. Since they are connected, there is an effect that the block members can be rotated with respect to each other to easily adjust the crossing angle, and it is possible to easily cope with different corner angles, thereby dramatically improving the work efficiency. You can Further, since the projecting portions of both block members are connected via the vertical axis, there is an effect that the fitting of the both block members does not come off, and the corner angle can be easily adjusted even after the block members are placed. .
