Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block holding tool capable of hoisting and carrying concrete blocks in a balanced manner.

[0002]

2. Description of the Related Art Conventionally, a square block having concaves and convexes or male and female fittings (including stacking and laying, the same applies hereinafter) to be installed on various slopes (of course, this is only an example and is limited to this block. Transporting or installing is usually done manually without the appropriate holding device. For example, a block to be installed next (uninstalled block) is arranged in a row above a group of blocks (referred to as installation blocks) installed on the slope at appropriate intervals. After that, after laying mortar for horizontal bases or for fixing in the interval, when the mortar is not hardened, quickly shift any one uninstalled block in the uninstalled block group for the next installation. Then, the non-installed block is fitted (top-stacked) with the convex piece of the installation block or the convex piece of the adjacent installation block with the concave piece in the two-sided direction of the non-installed block. As a result, the uninstalled blocks are laid in order on the lower and adjacent installation blocks. After that, each uninstalled block of the uninstalled block group is sequentially laid through the same manual work and procedure as described above, thereby completing the installation of the uninstalled block group.

[0003]

Since the block transportation or installation work detailed above is a manual work,
It puts an excessive burden on the worker, and has many problems in health, work environment, work speed, and the like. Further, when the uninstalled block is fitted into the installation block, the mortar surface is shifted because the uninstalled block is heavy, so that the uninstalled block is fitted into the installation block. As a result, for example, inconvenient phenomena such as mortar intruding between the concavo-convex pieces of the block, or mortar intruding (engaging) between the concavo-convex pieces occur frequently. Therefore, inaccurate fitting or a horizontal surface is not achieved, which causes a problem. For example, after removing and cleaning the mortar that has been eaten, double fitting such as fitting work again,
There are problems such as the extra work of three layers is required, which is very troublesome, the work efficiency is remarkably reduced, and many workers are required. In addition, a situation in which the mortar surface is scraped off by the shifting operation and the horizontal surface of the block is not ensured easily occurs, and the same problem as described above can be considered.

A block holding tool having a pair of holding claws and the like is also conceivable, but at least one of the holding claws is an obstacle in a block installation work in which the two directions are fitted, and it cannot be used sufficiently. It is unsuitable as a seed block installation work jig. Also, in the holding suspension method,
It is very dangerous because the block easily falls due to impact during transportation of the block, for example, vertical movement, horizontal shake, and various other shaking during transportation.

[0005]

Therefore, according to the present invention, a block or the like can be lifted with one touch and reliably, and a substantially U-shaped holding portion that can be installed at the installation place in this state is formed.
Even if various shocks are applied during lifting and transport,
The following configurations have been adopted for the purpose of immediately returning to a normal hoisting state without slipping off, and being able to directly carry the hoisted block to a predetermined installation position and install it using a gap .

That is, the block holding tool which can be lifted and carried with a sense of balance according to the present invention includes an upper and lower frame portion and this upper and lower frame portion.

[0007]

The function of the present invention (lifting, transportation and installation) will be described below.

First, mortar is laid on an inclined slope (hereinafter, simply referred to as a slope) (of course, mortar laying and
In some cases, the block installation described below may be performed almost at the same time. ). To install a block on the slope (see FIG. 4) on which this mortar is laid, first, between blocks stacked on a placing frame (pallet) or between overlapping portions such as a placing frame and a block, The tapered getter is bitten to facilitate insertion of a pair of lower frame portions (hereinafter simply referred to as lower frame portions, but not limited to a pair; the same applies below) of the main body of the holding device to the lifting target block (of course, It can also be done manually (see Figures 5 and 6).

[0009] Subsequently, on one side of the lifting target block, and holding so as to spliced pair of upper and lower frame portions, substantially
Using the U-shaped holding part , the upper and lower surfaces of about 1/2 of the block are sandwiched, and the uneven edge of the rising frame part is brought into contact with the uneven piece of the block. At this time, the hoisting fulcrum of the hoisting string (referred to as the hoisting part of the hoisting string) locked to the upper frame portion is located in front of the center of gravity of the block (block
The insertion side. It is an indispensable condition to be located in the same below) (see FIG. 7).

Thereafter, when the hoisting string is tensioned and the block is hoisted, the block is hoisted in an inclined shape because the locking part of the hoisting string is located forward of the center of gravity of the block as described above (see FIG. 8). This allows
Even if the hanging string returns to its normal state even if the hanging string moves, moves up and down, or changes due to a complicated motion, the holding tool body and block immediately return to their original positions. , The block never slides down. In particular, since the substantially U-shaped holding portion holds about 1/2 of the block, the block is effective for preventing the block from slipping off orthogonally to the lifting direction due to the deviation of the respective directions. When the block is hoisted, there is a gap between the bent piece and the top of the block,
The gap plays a cushioning role, and if the lifting string moves blindly,
However, the block and the main body of the holding tool do not hit each other, and the block is not scratched or slipped off, which is very useful. Therefore, the holding tool body of the present invention is substantially U-shaped.
It is very safe to suspend and carry the block through the holding part and the lifting cord that is locked to the bent piece.
In addition, even if the heavy equipment is out of place, the block can be safely lifted, transported, or installed as described later.

The block hoisted through the above-mentioned operation is then transported to the installation site, and is usually at a predetermined installation site using the guide line as a guide, and on the mortar laid on the block, the holding tool body of the block is held. Place from the hip side (the rising frame side, the same hereafter), and lift it up (open side of the holding tool body) and one side surface directly above the rear surface of the lower installation block or directly on one side surface of the adjacent installation block. Position (see FIG. 9). In principle, the work of installing the block is guided by the operator.

Then, while the hoisting string is loosened, the block is installed while being manually guided so as to be fitted to the rear surface of the installation block or one side surface of the adjacent installation block (see FIG. 10). At this time, by utilizing the gap , it is useful for facilitating or labor saving at the time of lifting the rear (non-fitting side) corner of the block, and the block can be installed smoothly and surely. In this way, once the block is in place, then, for example,
While pulling up the used gripping tool body while lifting the rear part of the block (the opposite side of the front part ) (Fig. 11).
At this time, as described above, a simple and reliable installation can be achieved through the gap . Installation of the block is complete.

After that, a large number of blocks are installed in order and speedily through the same operations and procedures as described above.
