DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger for a block used for transporting and constructing a concrete block or the like, and more particularly to a hanger for a block laid on a slope.

[0002]

2. Description of the Related Art A block body laid on a slope, particularly, an end face thereof is brought into contact with each other to entirely cover the slope, and a through hole is appropriately formed to form a communication hole in a vertical direction of the slope. Wire ropes and synthetic resin ropes were used when transporting and constructing the penetrating blocks.

[0003]

As a method for locking the rope, two ropes are arranged separately on the lower surface of the block body, or the two ropes are inserted into the through holes of the block body to balance the rope. It is troublesome to lock or release the ropes at the start of the lifting of the block body and at the end of the installation, and it is very difficult to lift the block body in a well-balanced manner with a predetermined gradient. There was a problem. In addition, since this kind of block body is laid directly on the slope surface from the lower side of the slope in order from the lower side and abutting the end surfaces, the rope is in contact with the existing lower block body in the locking method. There is a difficulty that the upper and lower blocks do not adhere to each other at the joint end surface, and the rope sandwiched between the blocks having a large mass after installation must be pulled out. Furthermore, when a wire rope is used, there is a problem that the block body is damaged and the commercial value is reduced.

[0004]

In other words, the means for solving the above-mentioned problems of the present invention is that the locking culms 1, 1 provided separately and the hanging culms 2 provided at the upper part of the center thereof are respectively provided. At the rear end portion, it is continuously connected in a U-shape in a side view by the connecting member 3,
A plurality of slope adjusting holes 4 are provided in the hanging culm 2 to adjust the hanging state of the block, and a holding metal fitting 5 which is vertically rotatable at the front thereof is pin-joined at the rear end thereof. The holding member 5 is composed of two plate members 5a and 5a sandwiching the hanging culm 2 and a backing plate 5b provided on the lower surface of the front end portion thereof. When the body 9a crosses between the plate members 5a, 5a, the bar 9a comes into contact with the upper or lower surface of the hanging culm 2 to prevent the holding member 5 from rotating. To provide.

[0005]

According to the present invention, since the present invention is constructed as described above, the locking culms provided separately are inserted into the through holes penetrating through the block body, and are inserted into the slope adjusting holes provided in the hanging culms. When fixing the shackle, locking the rope etc. and lifting it,
There is an effect that the attachment and detachment of the hanging tool can be easily and quickly performed and the block can be suspended with a desired gradient without damaging the block.

Further, even if the locking culm is inserted from above the block body having the inclined slope and the block body is inclined downward together with the block hanging tool, the holding fitting provided on the hanging culm comes into contact with the block body. Since the sliding is prevented to prevent the sliding, the safe use can be performed even on a steep slope, and the operation and effect that the block hanging tool does not interfere with the installation can be obtained.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 3, two rods are separated from each other in the left-right direction when viewed from the front to form locking culms 1, 1, and are plate-shaped provided at the upper central part of the locking culms 1, 1. Of the hanging culm 2 and the retaining culms 1 and 1 are connected to each other at a rear end portion thereof by a connecting member 3 in a U-shape in a side view. The suspension culm 2 is provided with a plurality of gradient adjusting holes 4a, 4b, 4c, and 4d from a substantially 1/3 portion to a rear end portion from a front end thereof in a side view.

[0008] In addition, two plate members 5a,
5a, the hanging culm 2 is sandwiched by
At the rear end of a, a holding metal fitting 5 is provided which is rotatably joined to the hanging culm 2 by a pin 6 and has a backing plate 5b fixed to the lower surface of the front end.

Further, a plate member 5 constituting the holding member 5 is provided.
a, 5a, supporting plates 7a, 7b
Is projecting perpendicularly to the plate member 5a, and two annular ring bodies 8, 8 are fixed to the upper surface of the one support plate 7a at intervals, and are provided at an intermediate portion between the ring bodies 8, 8. Secures a C-shaped metal piece 8a whose upper surface is cut off, and secures one ring body 8 on the other support plate 7b. A slide culm 9 composed of a circular rod 9a and a plate-like stopper 9b is fitted into the inner cavity of each of the ring bodies 8 and the C-shaped metal piece 8a.

Next, the operation of the holding member 5 will be described. In the state of FIG. 4A, the stopper 9b of the slide culm 9 is positioned between the ring body 8 at the outer end on the support plate 7a and the C-shaped metal piece 8a while the holding metal 5 is free to rotate. At the same time, the end 9c of the rod 9a is housed in the ring 8 at the inner end. In this state, the hanging culm 2 is
Since it is possible to pass through the gap between a and 5a, the holding metal member 5 is rotatable up and down around the pin 6.

In the state shown in FIG. 4 (b), the stopper 9b of the slide culm 9 is connected to the C-shaped metal member 8a on the support plate 7a and the ring member 8 at the inner end when the rotation of the holding member 5 is prevented. And the end 9c of the rod 9a is supported by the support plate 7b.
It is housed in the upper ring body 8. In this state, since the rod 9a of the slide culm 9 crosses between the plate members 5a and 5a, the rod 9a abuts on the lower surface of the suspension culm 2 and prevents the holding metal 5 from turning upward. Similarly, FIG. 3 shows a state in which the rod 9a abuts on the upper surface of the hanging culm 2 to prevent the holding metal 5 from rotating downward.

The movement of the slide culm 9 is controlled by the stopper 9.
b can be used as a gripping portion to give a small rotation to the stopper 9b and to pass through the cutout portion of the C-shaped metal piece 8a, and the stopper 9b can be fitted and fixed between the ring body 8 and the C-shaped metal piece 8a. Thus, unexpected sliding of the slide culm 9 is prevented.

Next, the block hanger 1 having the above-described structure.
A method of suspending the block body 12 using 0 will be described. First, as shown in FIGS. 5 and 6, a block body 1 having through holes 12a, 12a provided at appropriate intervals is provided.
When hanging 2 horizontally, the shackle 11 is attached to the slope adjusting hole 4a positioned so that the hanging state is horizontal on the hanging culm 2 of the block hanging tool 10. Then, the rotation of the holding member 5 is lifted above the hanging culm 2 in a free state, that is, the state of FIG. 4A, and the rotation of the holding member 5 is prevented from rotating downward, that is, the state of FIG. Is fixed to the slide culm 9. In this state, the locking culm 1, 1 through hole 1
The block body 12 is suspended in a horizontal state when the block body 12 is inserted into the shackle 11 and lifted up by locking it with a rope or the like. At this time, since the holding member 5 is fixed above the hanging culm 2, it does not become an obstacle when the attaching / detaching operation of the block hanging member 10 is performed.

Next, in FIG. 7 and FIG.
In the case where the suspension is performed with a slope applied to the suspension 2, the state of the holding metal 5 is fixed to a state of preventing downward rotation (the state of FIG. 3), and the suspension state of the suspension culm 2 is steep. The shackle 11 is attached to the slope adjustment hole 4d positioned as possible, and the block hanging tool 10 is attached to the block body 12. Then, the holding member 5 is set in a freely rotatable state (the state shown in FIG. 4A) so that the abutment plate 5b is brought into contact with the block body 12 and a state in which the holding member 5 is prevented from rotating upward (FIG. 4). The slide culm 9 is fixed in (b). If it is lifted in this state, the block 12
Can be suspended with a steep slope. At this time, the block body 12 is hung downwardly in a slant together with the block hanger 10, but the holding member 5, which is prevented from turning upward, prevents the block body 12 from sliding and is locked. Culm 1
To prevent them from slipping off.

The suspension gradient of the block body 12 can be arbitrarily set at a position where the gradient adjustment hole extends from horizontal to steep, and the shackle 11 is moved to the gradient adjustment hole 4b as shown in FIG. It can be easily adjusted to a gentle gradient.

Also, as shown in FIG.
The block body 12 slides on the locking culm 1 by forming the upper surface in a saw-tooth shape 1a or by covering the locking culm 1 with an elastic body 1b such as rubber or urethane as shown in FIG. Movement can be further prevented.

[0017]

As described above, according to the present invention, the holding metal is rotatably or fixedly provided on the suspension culm continuously connected in a U-shape when viewed from the side with the locking culm provided separately. Because it is a hanging device for a block, the block can be hung in a well-balanced manner by simply inserting the locking culm into the through hole provided in the block, and the work of attaching and detaching the hanging can be performed easily and quickly. It came to work.

Further, since the contact portion between the block hanging tool and the block body is only the locking culm and the through hole, there is a special effect that the block body can be hung without damaging the appearance of the block body. .

Further, when the suspension block is installed on the already installed block, the locking culm can be inserted from above the block having the inclined gradient, and the block hanging tool comes into contact with the existing block. Since the blocks do not interfere with the installation, the blocks are firmly attached to each other at the same time as the installation and the construction is labor-saving. Is in contact with the block body to prevent the sliding of the block body and prevent the block body from slipping down, so that an excellent effect that the safer use can be performed even on a steep slope is provided.
