Abstract

The present invention provides a connector that can easily and quickly fasten a plurality of concrete blocks on which an annular connector is arranged.
A connecting tool 7 is used for connecting annular connecting metal fittings 8 projectingly molded so as to be perpendicular to a construction surface with respect to a joint portion of concrete blocks 6 arranged in the same row on the construction surface. It is characterized in that it has a circular shape so that a plurality of coupling fittings can be connected simultaneously.

Description

  The present invention relates to a concrete block connector, and relates to a connector for connecting a river bank and a root block.

  Revetments such as rivers, lakes, and ponds may use large cover blocks and landscape blocks for reinforcement and protection. The blocks are arranged in a balanced manner with respect to the revetment slope, and these blocks are generally arranged with an annular coupling metal, and are usually arranged perpendicular to the existing block surface.

  To prevent these blocks from being scattered by running water and collapsing due to slippage of the revetment slope, it is necessary to fix all of the annular connecting fittings with connecting tools.

  The space for mounting this connecting device is often limited and narrow, and therefore a connecting device that is as small as possible is desirable, and a plurality of annular connecting devices must be fastened as quickly and simply as possible with one connecting device.

  In order to fix a plurality of large blocks with a single connecting tool, a shackle having a predetermined strength is often used.

  However, it is difficult for a small shackle to fasten a plurality of connecting brackets with one piece, and there are many cases where two or three pieces are used. This is because the revetment slope is not completely uniform, and the block installation method is also in conformity with the slope, and therefore the annular connecting bracket is often not uniform.

  It is difficult to fasten multiple annular connecting brackets with small shackles, but it is possible to fasten multiple annular connecting brackets with large shackles, but the bolts become long, so long bolts make workability difficult when fixing in small gaps There are drawbacks.

  In addition, when fixing with bolts, small bolts fall into the gap between the blocks to use gloves and work gloves, and workability is poor.

  Therefore, the present invention uses a short bolt, which is an advantage of a small shackle, and a small opening that can be inserted into a bolt even in a narrow space. As shown in FIG. As described above, a plurality of annular coupling fittings can be fastened.

  Even if the ring fittings are installed unevenly, the area that can be bundled is wider than a U-shaped shackle due to the circular shape of the fittings, and the workability can be mounted in a circle, making it easy to install multiple pieces. The annular connecting bracket can be stopped.

Because the bolts used for shackles are small and short, they are easy to lose once removed.
Therefore, in the present invention, as shown in FIG. 2, a nut is attached to the threaded portion of the bolt so that it cannot be removed even if the bolt is removed.

  Since the concrete block connector of the present invention has a circular shape, it is easy to fasten a plurality of annular connection fittings arranged on the concrete block, which can contribute to the efficiency of on-site construction and has a simple structure. Therefore, the price is also low, and it can contribute to cost reduction with workability and price.

  The circular shackle of the present invention has a retaining nut inserted into the bolt in advance, so that the bolt will not come off completely, and it can be efficiently connected even in environments where it is difficult to handle small items such as work sites using work gloves I can work.

The top view of the coupling tool of the concrete block made into the circle which shows the 1st Example of this invention. The external view showing the open state of the bolt which gave the retaining ring which shows the 2nd Example of this invention, and the opening part of a coupling tool. The front view which shows the state which fixed the multiple 1st Example to the annular connection metal fitting of the concrete block. The front view which shows the state constructed with the common small shackle. The top view which shows the coupling tool shown in FIG. 3 with a concrete block.
