BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold for molding a retaining wall block used at a corner of a terrace.
The present invention relates to a mold that can mold a plurality of types of blocks having different apex angles with each mold.

[0002]

2. Description of the Related Art As a mold for forming L-shaped retaining wall blocks for corners having different apex angles, it is possible to swing and fix the columnar body on both sides of the columnar body standing upright from a base. There is known a formwork including an inner surface molding frame provided with a molding plate and an outer surface molding frame in which two vertically opposed sides of the molding plate are connected by a connecting member having flexibility. When molding a retaining wall block used at the corners of a terrace using such a conventional mold, the angles of the inner and outer molding frames are set according to the apex angle of the corners. It is necessary to fix the frame.

[0003]

A block having a vertical angle of 90 degrees, that is, a block bent at a right angle is most often used as a block for constructing a corner portion of a retaining wall. Even in a mold whose apex angle can be changed, it is most often used to form a block having an apex angle of 90 degrees.
At this time, in the mold having the conventional structure, the angle of the mold had to be set prior to the molding even when the block having the apex angle of 90 degrees was molded. In particular, the formwork of the conventional structure requires at least the setting of the angle and position of one of the end plate and one of the forming plates of the inner forming frame and the outer forming frame when setting the angle. There was a problem that the work was very troublesome.

In addition, in the conventional formwork, it is necessary to set the angle of the formwork when molding the block with the apex angle of 90 °, and the block with the apex angle of 90 ° and the blocks with other apex angles alternate. However, in the case of molding in the same manner, there is a problem that a great amount of time is consumed in the work for setting the angle of the mold.

According to the present invention, the angle setting work of a mold for molding blocks having different apex angles is extremely simple, and a reference apex angle peculiar to the form, for example, a block having an apex angle of 90 degrees is It is an object of the present invention to provide a mold that can be molded without performing setting work, and therefore can significantly reduce the time consumed for setting the angle of the mold.

[0006]

The mold of the present invention comprises a substantially integrated inner surface molding frame 2 in which two flat surface portions 3 and 4 are connected by a convex arc surface portion 5, and two flat surface portions 10 in the same manner. , 11 connected to each other by the concave arc surface portion 12, and the end plates 17 and 18
And the auxiliary molding plate 7 that extends horizontally from the upper side of the inner molding frame 2.
And an end face plate 22 for molding the inner end face of the block retainer
And a detachable L-shaped partition plate 20. One of the inner surface molding frame 2 and the outer surface molding frame 9 is attached so as to be movable or rotatable when the block is removed from the mold.

A fulcrum pin 8 is erected on the auxiliary molding plate 7 at the position of the circular arc center P of the circular arc surface portions 5 and 12 of the inner surface molding frame 2 and the outer surface molding frame 9. Although it is possible to provide a pin hole instead of the fulcrum pin 8, it is preferable to erect the fulcrum pin 8 in consideration of cleaning the mold. The partition plate 20 is provided with a pin hole 21 that fits into the fulcrum pin 8 on the contact surface with the auxiliary molding plate 7. When a pin hole is provided on the auxiliary molding plate 7 side instead of the fulcrum pin 8, a fulcrum pin fitted into this pin hole is provided on the partition plate 20 side.

The partition plate 20 has a side surface shape which is substantially the same as the cross section of the block to be molded, and the fulcrum pin 8 and the pin hole 21 are fitted to each other and placed on the auxiliary molding plate 7 and fixed. To be done. At this time, the tip portion of the partition plate 20 is inserted between the convex arc surface portion 5 of the inner surface forming frame and the concave arc surface portion 12 of the outer surface forming frame 9. The partition plate 20 is generally prepared as a member different from the end plates 17 and 18, and is attached as necessary, but it is also possible to use a structure shared with one or both end plates 17 and 18.

The end plate 22 is provided so that it can be fixed to a desired position on the auxiliary molding plate 7 by a magnet or a C-clamp, or blocks having different apex angles to be molded are prepared with different shapes and sizes. It is provided so that it can be fixed to the corresponding position of the partition plate 20.

[0010]

When a block having a vertical angle of 90 degrees is molded using the mold of the present invention, the partition plate 20 is removed and the end plate 17,
It suffices to fix 18 to both ends of the mold and perform molding. The block molded at this time is, as shown in FIG. 3, integrally provided with linear portions 36 and 37 on both sides of the central arc portion 35.

When molding the block 31 different from 90 degrees, as shown in FIG.
Is fitted to the fulcrum pin 8 and attached to the center of the form. Then, the partition plate 20 is rotated around the fulcrum pin 8 to fix the partition plate 20 at a position where the apex angle becomes a desired angle. Then, the end face plate 22 is fixed onto the auxiliary molding plate 7 so as to come into contact with the end plate 17 and the partition plate 20, and concrete is poured into the formed cavity 19.

When the apex angle is obtuse, as shown in FIG.
A block 31 having an arcuate portion 35 bent at an obtuse angle on one side and a linear portion 36 on only one side is formed. If ordinary L-shaped retaining wall blocks 34 are connected to both ends of this block 31, a retaining wall with an obtuse angle can be constructed.

When the angle of the corner is an acute angle, as shown in FIG. 5, the block 3 has an arc portion bent to one side at an obtuse angle.
3 and a block 3 having an arc portion bent to one side by 90 degrees
2 and the circular arc portions 35, 35 of the two blocks are connected to each other to construct a retaining wall of a corner portion having an acute apex angle.

EFFECTS OF THE INVENTION In the formwork of this invention, since the installation angle of the partition plate can be arbitrarily selected and the angle setting work of the formwork is easy, various apex angles corresponding to the corners of the terrace can be obtained. The blocks can be easily molded. Further, a block having an apex angle equal to the reference apex angle peculiar to the mold can be formed simply by removing the partition plate, and it is not necessary to perform a troublesome angle setting work. In addition, the retaining wall constructed using the block molded with the formwork of this invention has no connecting part at the center of the corner and is good-looking, and since the corner has an arc shape,
For example, when constructing a retaining wall along a road, the retaining wall may have a shape that does not hinder the smooth passage of vehicles.
