2. Description of the Related Art Conventionally, concrete secondary products are usually used when constructing earth retaining and drainage structures. The concrete secondary product is a concrete mold material or the like which is mainly made of concrete or rebar and hardened in a predetermined shape in advance, and includes a box culvert, an L-shaped retaining wall, a U-shaped gutter, and the like. For example, when constructing a structure using such a concrete secondary product, first, a desired place is dug, concrete is driven to form a foundation, and the structure is completed with the foundation completed. Mortar as an adjusting material is placed on the foundation so that the bottom is flat.
Laying about cm, put the concrete secondary product on it,
Complete the structure by installing it in place and height.

[0003]

However, as described above, when the concrete secondary product is placed on the mortar as the adjusting material to adjust the height of the entire gutter, the concrete secondary product is placed on the mortar. It was extremely difficult to adjust the timing of loading and the amount of mortar, and there were many parts that depended on the intuition of a skilled craftsman. Further, even if a craftsman having such a high level of construction work works, it may not be possible to install it according to the design value.

For this reason, measures such as using a bolt adjuster type in which a bolt is provided on the bottom of the concrete secondary product or adjusting the height by driving a wedge on the lower surface of the concrete secondary product. I was doing However, the bolt adjuster type has a drawback that it is very difficult to adjust the length of the bolt, which is troublesome, and it is difficult to judge the height unless it is installed. Also, when using a wedge, if a concrete secondary product that is extremely heavy is placed, the wedge may change the sliding height, or even if it is placed, the height will change with a slight touch. It had changed. And in the case of slightly moving it to the left and right before and after finely adjusting the secondary concrete product,
I had to lift the concrete secondary product again with a crane.

Therefore, according to the present invention, even a person who does not have a high level of construction technology can easily adjust the height of a structure by a concrete secondary product by a simple work, and install a fine adjustment after the concrete secondary product is installed. It is an object to provide an adjuster for installing a secondary concrete product that can be kept in the state.

The rectangular wedge-shaped convex portion 2a and the concave portion 2b are provided on the slope 2 of the first wedge member 1, and the same square-shaped convex portion 6a and the concave portion 6b are also formed on the slope 6 of the second wedge member 5. It is provided. The first wedge member 1 and the second wedge member 5 are both plastic molded products and are compatible with each other and can be shared.

For example, on the slope 2 of the first wedge member 1 whose one side is a triangle of about 5 cm to 8 cm, the convex portion 2a having a width of about 2 mm to 4 mm and the width of 3 mm to 5 mm are formed in the direction orthogonal to the inclination direction.
The recesses 2b of a certain degree are alternately arranged in the shape of a square wave with the top and bottom sides having a drop of about 2 mm to 5 mm. On the horizontal surface 3 which is the back surface of the slope 2 of the first wedge member 1, a plurality of corrugated corrugated lines 3a having a width and a height of about 0.5 mm to 2 mm are arranged in the same direction as the inclination direction of the slope 2. . This horizontal surface 3 becomes the bottom surface of the adjuster for installing the secondary concrete product. For example, the first wedge member 1 shown in FIG.
The convex portion 2a and the concave portion 2b of the book are provided in a square wave shape, and the eleven uneven lines 3a are provided on the horizontal plane 3 which is the bottom surface. The second wedge member 5 has the same shape as the first wedge member 1, the convex portion 6a and the concave portion 6b are provided on the slope 6 in a square wave shape, and the uneven surface 7a is formed on the horizontal surface 7 serving as the bottom surface. It is provided similarly to the member 1.

Then, the first wedge member 1 and the second wedge member 5 having the same shape are made to face each other with the slopes 2 and 6 facing each other, and the second wedge member 5 is placed on the first wedge member 1 as indicated by the alternate long and short dash line. By bringing them into contact with each other, the convex portions 2a, 6a and the concave portions 2b, 6b are combined with each other, and are fixed so as not to move vertically in the tilt direction. The widths of the concave portions 2b and 6b are the same as those of the convex portions 2a and
It is configured to be slightly wider than the width of 6a, so that it is easy to make a combination by bringing them into contact with each other. In such a concrete secondary product installation adjuster, the horizontal surface 3 of the first wedge member 1 serves as the bottom surface, and the horizontal surface 7 of the second wedge member 5 serves as the concrete secondary product contact surface.

As shown in FIG. 2, the first wedge member 1 and the second wedge member 1
When the slopes 2 and 6 of the wedge member 5 are opposed to each other, and the height A of the triangle of the cross section is 3 cm, for example, the slope 6 of the upper second wedge member 5 is lowered as shown by the solid line. The height A becomes approximately 3 cm, which is substantially the same as the height A of the triangular section, when the first wedge member 1 on the side is brought into contact with the slope 2 at substantially the same position. If the upper second wedge member 5 is located above the slope 2 of the lower first wedge member 1 as indicated by the chain double-dashed line, the height B
Is about 4 to 5 cm.

Next, a case will be described in which the concrete secondary product 11 is actually installed by using the concrete secondary product installation adjuster of the present embodiment. FIG. 3 is a front view showing a case in which a concrete secondary product is installed using the adjuster for installing a concrete secondary product according to the first embodiment of the present invention, and FIG. 4 is a concrete second embodiment according to the first embodiment of the present invention.

As shown in FIG. 3, when the concrete secondary product 11 is installed by using the concrete secondary product installation adjuster of the present embodiment, first, a predetermined reference position such as a target structure upper surface is set. The height of the adjuster is determined by back-calculating from the distance between the base 10 and the base. That is, the height of the adjuster is the difference between the reference position and the height of the foundation 10 and the height of the secondary concrete product 11. Then, as described above, the height of the adjuster for installing the concrete secondary product in which the first wedge member 1 and the second wedge member 5 are combined is adjusted, and the foundation 10 is positioned so as to be located on the bottom surface of the concrete secondary product 11. And laying the mortar 12 on it, the concrete secondary product 11 is placed on the adjuster. When the secondary concrete product has an opening at the bottom, the mortar 12 can be applied by post-casting.

At this time, when the position of the concrete secondary product 11 is finely adjusted after the concrete secondary product 11 is installed, it is the horizontal surface 7 of the second wedge member 5 as shown in FIG. 4 (a). Friction between the concrete secondary product 11 and the horizontal surface 7 is reduced by the uneven line 7a provided on the concrete secondary product contact surface, and the concrete secondary product 11 is
While resting on the combined adjuster, it can be moved left and right as shown by the chain double-dashed line.

The slopes 2 and 6 of the first wedge member 1 and the second wedge member 5 are prevented from moving up and down in the inclination direction, but friction in the direction orthogonal to the inclination direction is relatively small. As shown in FIG. 4A, the concrete secondary product 11 can be finely adjusted back and forth while being mounted on the combined concrete secondary product setting adjuster.

On the upper surface of the concrete secondary product setting adjuster in a combined state, a concrete secondary product setting adjuster similarly combined can be placed, and the adjuster calculated backward from the height of the target structure can be mounted. You can flexibly adjust the number of adjusters according to the height of.

Therefore, if the concrete secondary product setting adjuster in which the first wedge member 1 and the second wedge member 5 are combined as described above is used for setting the concrete secondary product 11, it has a high construction technique. Even a non-person can easily adjust the height of the structure by the concrete secondary product 11 with a simple operation. Moreover, since the height can be adjusted from the completed foundation, the height of the structure can be flexibly adjusted while staying at the work site. Further, after the concrete secondary product 11 is installed, the concrete secondary product 11 can be finely adjusted to the left, right, front and back while being placed on the concrete secondary product installation adjuster.

The material for the concrete secondary product installation adjuster is not necessarily limited to the plastic molded product, but may be any material capable of supporting the concrete secondary product 11, such as metal. It doesn't matter. The unevenness and size of the slopes 2 and 6 may also be changed according to the target structure and the secondary concrete product 11.

Further, the uneven lines 3a, 7a provided on the horizontal surfaces 3, 7 corresponding to the back surface of the slope may be any number as long as it can reduce the friction with the concrete secondary product with which it comes into contact, and the size and shape can be arbitrarily selected. .
