BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector used for constructing a lightweight embankment used as a countermeasure against soft ground when constructing structures such as roads, tracks and buildings on soft ground. More specifically, the embankment, which is carried out as a measure against soft ground, is not simply done by sand, but a hard foam plastic block (hereinafter referred to as "foam block") is piled up in order to hold the entire weight of the embankment within the bearing capacity of the soft ground. The present invention relates to a connecting tool for connecting foam blocks when using as an embankment substitute.

[0002]

2. Description of the Related Art Conventionally, as a connecting tool used for constructing the above-mentioned lightweight embankment, a rectangular plate-shaped body is diagonally cut and the part is folded up to remove the central part on the long side. It is known that a tooth is formed by using this method (JP-A-62-41822).

The above-mentioned connecting member extends between the foam blocks laid adjacent to each other in a plane, and is inserted by interposing the teeth into each of the foam blocks, and the foam blocks to be stacked are connected to each other. By doing so, the overall integration is enhanced.

[0004]

However, the conventional connecting tool has the following disadvantages in construction.

(1) In the case of the conventional connecting tool, when connecting two adjacent foam blocks, it is sufficient to install the connecting tool across one seam, so that it is provided in the central portion on the long side. By locating the seam of the foam block in the toothless region, the connection can be made without pushing the teeth to the edge of the foam block which is likely to be cracked or chipped.

However, when three or four foam blocks are connected at the same time, a connecting tool is installed across the joints intersecting in a T shape or a cross shape, and the teeth as described above are provided on the short side. Since there is no non-existent region, teeth easily stick to the edge of the foam block and cracks or chips are likely to occur in the foam block. Therefore, although it is effective to connect three or four foam blocks at the same time, such a connection is not possible.

(2) The conventional connecting tool is difficult to handle because the toothless part is only the central part on the long side and the region that can be gripped by hand is only the part on the long side.

The present invention has been made in view of the inconveniences of the above-described conventional connecting tool, and an object thereof is to provide a connecting tool having excellent workability and handleability.

[0009]

For this reason, in the present invention ,
As shown in FIG. 1, a series of teeth 2 protruding vertically and in the same direction are provided at each corner of the four corners of the plate-shaped body 1 except for the central part of each side of the plate-shaped body 1 having a flat rectangular shape. In the center portion of each side of the plate-shaped body 1 on which the teeth 2 are not provided, a protrusion 3 protruding in the plane direction is provided, and a notch 4 is provided in the center of the tip side of the protrusion 3. There is something.

[0010]

In the present invention, the central portion of each side of the plate 1 is
As shown in FIGS. 2 and 3, the protrusions 3 are provided with the teeth 2 at each of the four corners except for this portion, so that three or four foam blocks 5 are simultaneously formed. When connected, make sure that each seam of the foam block 5 has a protrusion without this tooth 2.
At the same time as making it correspond to the protruding portion 3,
Set it as far as possible from the edge of the foam block
Of. In addition, the teeth 2 protrude vertically and in the same direction.
There are three or four as shown in FIGS. 2 and 3.
When the foam blocks 5 of are connected simultaneously,
Provided on at least two sides perpendicular to the lock 5.
This is because the tooth 2 is stuck.

In the present invention, the protrusion 3 is provided at the tip side.
The cut portion 4 formed is as shown in FIG. 2 or FIG.
When connecting at the position, the seam of the foam block 5
It serves as a mark to align the positions. Also, the protrusion 3
Is also for grasping the main connector A without gripping the teeth 2 by grasping the protruding portion 3 from any side when the main connector A is grasped. is there.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a plate-like body 1 having a substantially square shape in plan view is provided with a projecting portion 3 protruding in a trapezoidal shape in the plane direction at the center of each side. Further, a triangular notch 4 is formed at the center of the tip of the protrusion 3.

The central portion of each side of the plate-like body 1, that is, the protruding portion 3
In each corner of the four corners of the plate-shaped body 1 excluding the formation location of
A series of triangular teeth 2 each projecting upward are provided.

The connecting tool A is generally formed of a metal plate, and can be manufactured by folding the tooth 2 after punching.

A method of using the connector A will be described with reference to FIGS.

The connecting tool A is particularly useful when three or four foam blocks 5 are simultaneously connected, and as shown in the drawing, a T-shaped or cross-shaped joint between the foam blocks 5. The three or four notches 4 of the connecting tool A are aligned with each other at the position of, and each tooth 2 (see FIG. 1) is pierced into the foam block 5 by stepping on from above, etc. Alternatively, the four foam blocks 5 can be simultaneously connected to each other.

At this time, the present connecting tool A straddles between the three or four foam blocks 5, and the teeth 2 are pierced into each of the three or four foam blocks. Since the tooth 2 is not formed at the central portion of each side of the body 1, that is, the location where the protruding portion 3 is formed, each tooth 2 is pierced at a position slightly apart from the end edge portion of each foam block 5.

On the other hand, the present connecting tool A can be used not only for the above-mentioned locations, but also for connecting two adjacent foam blocks 5 in the same manner as a conventional connecting tool. That is, as shown in FIG. 4, after arranging the main connecting tool A by aligning the positions of the notches 4 at the positions opposite to each other with respect to the joint between the two adjacent foam blocks 5, the same operation is performed. By pushing the tooth 2 into both foam blocks 5, the two foam blocks can be connected to each other.

[0019]

The present invention is as described above and has the following effects.

(1) In the present invention, each side of the plate-shaped body 1
The central part of is the protruding part 3 and each of the four corners except this part
Since the tooth 2 is provided at the corner portion, the tooth 2 shown in FIGS.
As shown in Fig. 3, install three or four foam blocks 5
When connecting, make sure that each seam of the foam block 5 is
At the same time it is possible to accommodate the protruding portion 3 without the tooth 2 of
In addition, the position where the tooth 2 pierces is separated from the edge of the foam block.
It will be in a dislocated position. Therefore, the teeth 2 are attached to the edge of the foam block 5.
It is possible to connect three or four foam blocks at the same time without causing cracking or chipping of the edge due to puncture by the, and the connection can be effectively performed.

(2) One side of the plate-like body 1 on the foam block 5
If only the tooth 2 provided on the
When a force in the same direction as is applied, the foam block 5 tears
Sui. However, in the present invention, the tooth 2 has four corners.
2 and FIG. 3 because they project in the same direction and perpendicular to
Simultaneously with three or four foam blocks 5 as shown in
When connecting the foam blocks 5,
Set on at least two sides that are orthogonal (two sides that make up the corner)
The dented tooth 2 pierces and prevents such tearing.
It

(3) Since the main connecting tool A has the notch 4 serving as a positioning mark, it is easy to install the main connecting tool A at an accurate position, and the foam block 5 is not cracked or chipped. Prevention becomes more reliable. Also, tooth 2 is installed on 4 sides.
Since there is a protrusion 3 that is not scraped off, from which side
However , the connector A can be gripped and the handleability is excellent.
