Abstract

PROBLEM TO BE SOLVED: To allow the application of a lifting force to a plate type material but prevent the action of a buckling force thereon at a lifting process by supporting the plate type material with a lifting sling body and hoisting the lifting sling body via a suspension rope. SOLUTION: A lifting jig 11 is formed to be capable of hoisting a plate type material 10, and made of a hoisting jig 19 as well as a suspension rope 20 as a suspension cord. Also, the lifting jig body 19 has a plurality of holding plates 22, for example, two long-sized holding plates 22 suspended from the reverse side of a long-sized top plate 21, and is formed to allow the plate type material 10 to be inserted in space between the holding plates 22. Screws holes 23 are drilled through both end parts of each holding plate 22, and support bolts 24 arc screwed to the screw holes 23. Then, the support bolts 24 are inserted in the suspension holes 18 of the plate material 10, thereby holding both ends of the plate type material 10 on the lifting jig body 19. According to this construction, the lifting jib body 19 does not undergo buckling deformation, even upon action to a buckling force A, because of the existence of the holding plates 22.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transporting a plate-like body, for example, a plate-like body, which facilitates lifting and transporting a reinforcing beam.

[0002]

2. Description of the Related Art When a plate such as a reinforcing beam used in a unit building is installed on a construction site, the plate is lifted and transported.

At this time, as shown in FIG. 6A, suspension holes 2 are opened at both ends of the reinforcing beam 1 from the viewpoint of strength, and a suspension rope 3 is attached to the suspension holes 2. Then, the reinforcing beam 1 is suspended by the suspension rope 3.

[0004]

However, the reinforcing beam 1 has a long shape, and the suspension holes 2 at both ends thereof are connected to the suspension ropes 3.
When the supporting beam 1 is lifted, a vertical upward lifting force F and a buckling force A facing each other in the horizontal direction act on the reinforcing beam 1 from the suspension rope 3 when the reinforcing beam 1 is lifted. Due to the buckling force A, as shown in FIG. 6B, the reinforcing beam 1 is buckled and deformed in the horizontal direction when the reinforcing beam 1 is lifted.
The reinforcing beam 1 is bent and deformed by the action of its own weight acting on the reinforcing beam 1, and the reinforcing beam 1 vibrates due to these deformations, and the installation work of the reinforcing beam 1 becomes a complicated operation.

SUMMARY OF THE INVENTION The object of the present invention has been made in view of the above-mentioned circumstances, and to provide an apparatus for transporting a plate-like body which can prevent deformation of the plate-like body during lifting or transportation. It is in.

A hanging jig main body capable of supporting the body is provided, and a suspension cable attached to the hanging jig main body and capable of lifting the hanging jig main body.

According to a second aspect of the present invention, in the first aspect of the present invention, the hanging jig body supports both ends of the plate-like body.

[0008] The invention according to claim 3 is the invention according to claim 1 or 2.
In the invention described in the above, a transport gantry on which the plate-like body can be placed is provided, and this transport gantry is provided so as to be integrated with the hanging jig body, and the plate-like body is provided between the hanging jig body. Can be held.

According to a fourth aspect of the present invention, in the first aspect of the present invention, at least one of the hanging jig main body and the transport gantry is made of metal.

According to a fifth aspect of the present invention, in the first aspect of the present invention, the plate-like member is a reinforcing member for connecting ceiling beams of the building units installed adjacent to each other. It is made to be a beam.

According to a sixth aspect of the present invention, the hanging jig body includes a long-shaped top plate, and a holding plate vertically suspended from the top plate and holding the reinforcing beam according to the fifth aspect, The top plate serves as a casting surface when the reinforcing beam is inserted between the ceiling beams of the building unit.

[0012]

The invention according to claim 1, 5 or 6 has the following effects. Since the plate-like body (reinforcement beam) is supported by the hanging jig body, and the hanging jig body is hung by the hanging jig, the lifting jig main body is lifted vertically from the hanging jig to the lifting jig main body during the lifting. Although a force and a buckling force in directions facing each other in the horizontal direction act on the plate-like body, the lifting force acts on the plate-shaped body, but the buckling force does not act. For this reason, the plate-like body does not buckle and deform during lifting, and as a result, vibration due to the buckling deformation and the like does not occur, so that the lifting operation can be performed safely.

Further, since the plate-like body (reinforcement beam) can be installed while being attached to the hanging jig main body, the hanging jig main body is thrown with a tool such as a hammer to perform fine positioning. Even so, it is possible to prevent the plate-shaped body from being hit and deformed, and the surface-treated portion from being damaged.

The second aspect of the invention has the following operation. When both ends of the plate-like body, especially the long plate-like body are directly supported and suspended by the suspension cable, a large buckling force acts on the plate-like body in the horizontal direction from the suspension cable, Since both ends of the plate are supported by the hanging jig body, no buckling force acts on the plate, and buckling deformation and vibration of the plate can be prevented.

The invention according to claim 3 or 5 has the following operation. In a state where the plate-like body (reinforcement beam) is mounted on the hanging jig body, the plate-like body is placed on a transportation gantry, and the transportation gantry and the hanging jig body are integrated to form a plate-like body. , Since it is held by the hanging jig main body and the transport frame, it is possible to prevent deformation of the plate-like body during transportation and damage to the surface treatment portion applied to the plate-like body, and as a result, Handling and transportation can be facilitated.

The invention described in claim 4 has the following operation. Since at least one of the hanging jig body and the transport gantry is made of metal, it can be used repeatedly as compared with a case where these are made of wood, and the cost of the transport device can be reduced.
