BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tension block which covers the surface of a slope and is lined up to protect the slope.

[0002]

2. Description of the Related Art Conventional upholstery blocks have been formed in a simple plate shape.

[0003]

Since the conventional upholstery block is formed in a simple plate shape, the top of the slope is
At the lowermost portion and other portions where the slope changes, the joint portion of the block bends instead of being straight, and therefore the block has a thickness, so that a gap occurs at the joint portion. Therefore, it has been dealt with by notching the side surface of the block so that no gap is formed or filling the gap at the joint with mortar or the like. Therefore, the construction was complicated and the work efficiency was poor.

[0004]

SUMMARY OF THE INVENTION The present invention is a tension block, wherein a plurality of concrete plates are joined by a band-shaped elastic body such as rubber, and the joint portions can be bent. Normally, two concrete plates are connected by a band-shaped elastic body, but in special cases such as when using an extremely complicated slope, three or more concrete plates may be connected. It is desirable that the strip-shaped elastic body is embedded in the concrete before the concrete is hardened and is completely integrated with the concrete plate. The strip-shaped elastic body is embedded almost in the center of the thickness of the concrete plate, and the front and back corners of the concrete plate end of the joint portion joined by the strip-shaped elastic body are cut out to form a chamfer, and the cross section of the joint portion is formed into a substantially X shape. If formed, a more suitable stretch block can be obtained.

[0005]

Since the upholstery block of the present invention is bent at the connecting portion, when it is installed at a place where the inclination changes, it can be easily installed by bending along the slope. Moreover,
Since the joint part is stopped by the elastic band, rainwater does not easily penetrate into the ground and there is little risk of loosening the ground. The strip-shaped elastic body is embedded almost in the center of the thickness of the concrete plate, and the front and back corners of the concrete plate end of the joint portion joined by the strip-shaped elastic body are cut out to form chamfers, and the cross section of the joint portion is approximately X.
If it is formed in a letter shape, it can be easily bent to either the front side or the back side without giving a load to the band-shaped elastic body, and it is possible to minimize the exposure of the band-shaped elastic body from the concrete.

1 is a perspective view of a tension block 1 according to one embodiment of the present invention. The tension block 1 is formed by integrally joining two concrete plates 2 and 2 with a belt-shaped elastic body 3 made of rubber. The band-shaped elastic body 3 is embedded in concrete before hardening at the time of block molding, and is completely integrated with the concrete. Both ends of the strip-shaped elastic body are bulged in a circular shape in cross section so that they cannot be easily separated from the concrete. Both ends of the concrete plate 2 of the joint portion joined by the band-shaped elastic body are notched at both corners to form a chamfered portion 4, and as a result, the joint portion has a substantially X-shaped cross section. Therefore, the tension block 1 can be freely bent up to about 90 degrees at the joint portion.

2 and 3 show an example of construction of the tension block 1. FIG. 2 shows the case where the work is applied to the top of the slope, and FIG. 3 shows the case where the work is applied to the bottom of the slope. In both cases, the construction is extremely simple, and the joint portion of the upholstery block 1 bends naturally as the slope of the slope changes. Reference numeral 5 in the figure is a conventional single tension block, and the conventional single tension block is used for the general portion where the slope does not change.

[0008]

EFFECTS OF THE INVENTION Since the upholstery block of the present invention bends freely, if it is used on a slope where the slope changes, it naturally bends along with the change of the slope and improves work efficiency. You can In addition, the part where the slope of the slope changes is
Especially, the natural ground is easy to loosen, but the tension block of the present invention has a water blocking effect at the joint portion, and also has an effect of suppressing the looseness of the natural ground.
