DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple detachable unit panel gripper used to lift a unit panel such as a lightweight cellular concrete (ALC) plate, an extruded plate or a precast concrete (PC) plate. is there.

[0002]

2. Description of the Related Art ALC or extruded plates or PC unit panels have been widely used for floors, outer walls, partitions, etc. of steel frames and RC structures. Conventionally, when such a unit panel is to be suspended. A piece of a gripping tool in which a holding bolt is provided in advance in a gap between the angle fixed to an upper edge of the unit panel main body at a predetermined gap with the upper edge thereof and a unit panel main body. Is inserted, and the bolt is tightened to firmly attach the gripper to one side of the angle. Thereafter, a wire is slung on the gripper and the unit panel is lifted using a crane or the like.

[0003]

As described above, in the conventional gripping device for the unit panel, a bolt tightening operation is required at the time of attachment, and the bolt provided in advance in the gripping device is attached to the ratchet. It requires a lot of work, which takes a lot of time and labor, resulting in poor work efficiency, delay of construction period and increase in cost.

Further, according to the conventional gripping tool, the gripping tool is attached to one of the angles at the upper part of the unit panel only by the frictional force of bolt tightening. Even if the bolts are weak and loose, it is difficult to detect them visually, and if for some reason a horizontal force is applied to the unit panel while the unit panel is suspended, the unit panel will come off the gripper There is another problem that there is a risk of falling.

An object of the present invention is to provide a unit panel gripper which can solve the above-mentioned problems in the prior art.

[0006]

According to the present invention, there is provided a unit panel gripper attached to an angle fixed to an upper end of a unit panel main body for hanging the unit panel. There is provided a main body having an insertion plate portion inserted into a gap between the angle and the upper end portion, and a wedge holder fixed to the main body, and the insertion plate portion is inserted into the gap. After inserting, a unit that drops a wedge fitting through a holding plate through the wedge receiving unit and locks the holding plate at the angle to prevent the insertion plate portion from coming out of the gap. A panel gripper is proposed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a side view showing an example of an embodiment of a unit panel gripper according to the present invention. The unit panel gripper 1 is connected to the unit panel 2 for the purpose of hanging the unit panel 2 on a building floor.
The unit panel 2 shown in FIG. 1 has a known configuration in which an angle 22 for hanging is attached to an upper end portion 21A of a unit panel main body 21 made of an ALC plate along the width direction of the unit panel main body 21. The angle 22 is an ALC unit panel, the side 22A of which is covered at a predetermined interval from the upper end surface 21B of the unit panel body 21 so that a gap G is formed between the upper end surface 21B and the one side 22A. The unit panel body 21 is bolted to one side surface 21C by a known means.

The unit panel grip 1 has a main body 11 made of channel steel having a length substantially equal to the length of the unit panel main body 21 in the width direction. The main body 11 has a U-shaped cross section, and one right-angled bent portion of the main body 11 is an insertion plate 11A inserted into the gap G. By inserting the insertion plate 11A into the gap G, When the unit panel 2 is suspended, the unit panel grip 1 can be engaged with the unit panel 2. An L-shaped hanging metal fitting 31 for slinging with a hanging wire is fixed to the other right-angle bent part 11B of the main body 11 by welding.

FIG. 2 is a perspective view showing a main part of the unit panel gripper 1 shown in FIG. The unit panel grip 1 will be described with reference to FIGS. Main unit 1
A bracket 12 is fixed to the right-angled bent portion 11B by welding, and a wedge holder 13 is similarly fixed to the bracket 12 by welding.

The wedge fitting 13 corresponds to the wedge fitting 14, and the wedge hole 1 into which the wedge fitting 14 is dropped.
3A. As shown in FIG. 1, when the wedge fitting 14 is dropped into the wedge hole 13 </ b> A with the insertion plate portion 11 </ b> A inserted into the gap G, as shown in FIG. 22B
The bracket 12 is attached to the bracket 12 so as to be close to and opposed to the bracket 12.

Reference numeral 15 denotes a holding plate formed of a metal plate member having a through hole 15A through which a leading end portion of the wedge holder 13 passes through a central portion. The leading end of the wedge holder 13 is passed through the through hole 15A of the holding plate 15, and the wedge fitting 14 is inserted into the wedge hole 1.
3A, the upper end 15B of the holding plate 15 is locked to the bracket 12 and at the same time the lower end 15C is locked to the angle 22, whereby the unit panel gripper 1 and the unit panel 2 are connected. At the same time, the insertion plate portion 11A can be kept inserted into the gap G.

FIGS. 1 and 2 show a fixing mechanism A using a wedge holder 13, a wedge holder 14, and a holding plate 15. FIG.
Although only one set is shown, this fixing mechanism A is
A plurality can be provided at appropriate intervals along one longitudinal direction. The wedge hardware 14 and the holding plate 15 are attached to the right-angle bent portion 11B of the main body 11 by chains 16 and 17, respectively, to prevent loss.

Since the unit panel gripper 1 is configured as described above, the insertion plate portion 11A of the main body 11 is provided.
Is inserted into the gap G, and the leading end of the wedge holder 13 is passed through the through hole 15A of the holding plate 15 so that the wedge metal 1
4 can be reliably prevented from falling out of the gap G by dropping the insert plate portion 4 into the wedge hole 13A of the wedge holder 13.
Can be easily connected to the unit panel 2.
In addition, the connection between the unit panel gripper 1 and the unit panel 2 is not released by an external force acting in the thickness direction of the unit panel 2. Then, the connection state between the unit panel grip 1 and the unit panel 2 can be easily released only by pulling out the wedge hardware 14 from the wedge hole 13A. Further, the state of connection of the unit panel gripping tool 1 to the unit panel 2 can be determined only by visually checking the locked state of the wedge hardware 14 and the holding plate 15.

This structure can be easily manufactured using existing members, so that the cost can be reduced, and the connection and disconnection work is extremely simple as described above, so that a significant improvement in work efficiency can be expected.

[0016]

According to the present invention, as described above, after the insertion plate portion is inserted into the gap, the wedge fitting is dropped into the wedge hole of the wedge holder so that the holding plate is locked at an angle. Alone prevents the insertion plate part from coming out of the gap, and prevents the connection between the unit panel gripper and the unit panel from being released by external force acting in the thickness direction of the unit panel. can do. Then, only by pulling out the wedge hardware from the wedge hole, the connection state between the unit panel gripper and the unit panel can be easily released. Therefore, the connection and disconnection operations are extremely simple as described above, so that a remarkable improvement in operation efficiency can be expected, and the production can be easily performed using existing members, so that the cost can be reduced. Further, the state of connection of the unit panel gripper to the unit panel can be determined only by visually checking the locked state of the wedge hardware and the holding plate.
