Description

[Detailed description of the invention] This invention relates to a joint structure when continuously constructing retaining walls such as gutters, waterways, side walls, etc., and is a retaining wall that firmly connects retaining walls formed in block shapes. This is related to the joint structure of .

Conventionally, in order to connect this type of retaining wall, the edges of each block-shaped retaining wall are provided with concave and convex portions that fit into each other, or the edges are provided with recessed portions for pouring mortar. Structures have been adopted in which bolts are buried near the back edge of the vertical wall and the two vertical walls are connected by tightening the bolts, but the strength of the connection part may not be sufficient. However, there were drawbacks such as misalignment after connection.

This idea was made to improve the shortcomings of the conventional example mentioned above, and when connecting retaining walls formed in the shape of blocks, it is possible to accurately position them, and also to make it easy to construct and firmly connect them. The present invention provides a joint structure for a retaining wall configured as follows.

Hereinafter, one embodiment of this invention will be described in detail based on the attached drawings.

FIG. 1 is a perspective view of a retaining wall 1 according to this invention, in which a concave groove 2 whose bottom widens in the center is formed continuously in the height direction at the edges of both ends. Recesses 3 and protrusions 4 for preventing slippage and positioning are formed on the left and right sides of the sandwich. are fitted into each other for positioning and prevention of displacement.

In addition, when the above-mentioned retaining wall 1 is installed continuously, the concave groove portion 2 at the edge portion
A connecting fitting 5 is inserted into the.

As shown in the figure, the connecting fitting 5 is composed of supports 5a, 5a such as reinforcing bars corresponding to the height of the retaining wall 1, and horizontal members 5b and horizontal bars 5c fixed at predetermined intervals. It is inserted from above between the concave groove parts 2, 2.

In order to connect the retaining walls 1 configured as described above in series, as shown in FIG. After that, a connecting fitting 5 is fitted from above between the concave grooves 2 and 2 of the mouth portion, and then a mortar 6 for a predetermined purpose is injected to connect them.

Therefore, the connecting fitting 5 inserted between the concave grooves 2, 2 at the edges is fixed by the target mortar and becomes a reinforced concrete member, and since the bottoms of the concave grooves 2, 2 are widened, the connection is reliable.

As explained in detail above, the joint structure of the retaining wall according to this invention has recesses and protrusions for preventing slippage and positioning over the entire height of the edge, so it is easy to construct when installing them in series. , Moreover, after inserting the connecting fitting between the concave grooves and injecting the intended mortar to connect them,
Also, even in the event of an earthquake, there will be no displacement due to partial slippage, and since the entire retaining wall has an integral structure, it can be firmly connected without causing damage.

Also, according to the joint structure of the retaining wall invented by this invention,
It is ideal for connecting the side walls of side gutters, water gutters, etc., and since recesses and protrusions for preventing slippage and positioning are formed on both sides of the joint, the poured mortar will not leak and construction is easy.

Furthermore, it is extremely easy to install connecting fittings in the concave grooves at the edges and inject mortar from the top after the retaining wall has been installed, making construction extremely easy. is remarkable.
