Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a retaining wall forming block that can be easily loaded and unloaded and is safe.

[Problems to be solved by conventional techniques and devices]

Blocks for forming retaining walls Especially large products are transported to the site by truck, hoisted by a crane etc., moved to a predetermined position, hoisted and set on a concrete foundation.

When suspending this retaining wall forming block, a suspending hook must be hung somewhere on the retaining wall block.

If the hanging hook comes off during lifting and lowering, not only the retaining wall forming block will be damaged but also the worker will be in danger.

The present invention provides a retaining wall forming block that solves this problem.

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

A reinforcing bar 3 is attached to the rear surface of the retaining wall block a composed of the front wall 1 and the bottom wall 2 so that the center of gravity of the retaining wall block a is located near the attachment portion of the reinforcing bar 3 to the front wall 1. The retaining wall forming block is characterized in that a fitting groove 4 for locking a hanging hook is provided on the lower surface of the upper portion of the reinforcing bar 3 attached to the front wall 1.

[Operation] Since the fitting groove 4 is provided substantially at the center of gravity, when the hanging hook 5 is applied to the fitting groove 4, the retaining wall block a can be lifted and lowered in a stable posture, and the fitting groove 4 is fitted into the fitting groove 4. Therefore, the hanging hook 5 does not come off.

〔Example〕

 The drawing shows the case where the fitting grooves 4 are arranged in parallel.

Since the window 6 is opened below the reinforcing bar 3, the hanging hook 5 is more easily hooked. The window 6 may be divided into upper and lower two stages or three stages by horizontal reinforcing bars.

Even when a wire is suspended instead of the hanging hook 5, it is similarly easy to hang and does not come off. Further, FIG. 2 shows a case where the reinforcing bars 3 are arranged side by side, and in this case, two reinforcing hooks 5 are lifted in a balanced manner, but one reinforcing bar 3 is provided at the center.

In the figure, reference numeral 8 is a cement milk inlet, 9 is a center of gravity bolt, 10 is a fixing bolt, and 11 is a connecting piece with a connecting hole 7.

[Effect of device]

According to the present invention, since the center of gravity is located near the portion where the reinforcing bar is attached to the front wall as described above, it is possible to always lift and hang while maintaining a stable installation state. It is a retaining wall forming block that has excellent features that make it easy to install because it can be easily suspended because it is easy to apply and does not come off.
