Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plate material hanging jig for hanging a plate material having a hollow hole, such as an extruded cement molded plate, particularly in the vertical direction.

[0002]

[Prior art]

 Conventionally, as a method of suspending this kind of plate material, as shown in FIG. 9, a single method is used to suspend the middle of the plate material P with a nylon sling S, or as shown in FIG. 10, the upper end portion of the plate material P is suspended. There was a method of sandwiching and lifting by the clamp R.

However, in the method using the nylon sling S, the plate material P may slip and drop, which is not only a safety problem, but also requires a clearance for pulling out the sling S. However, it was impossible to set the plate materials P in close contact with the existing plate materials P, or it was necessary to float the plate materials P stacked horizontally when lifting.

In addition, in the method using the clamp R, the clamp cannot be opened when the clearance dimension with the base side is small, and the plate P has a concentrated force at the tip of the clamp R, resulting in a damage accident. There was a problem that it was easy. Therefore, these conventional methods have a problem that, in the case of hoisting work using a crane, the regulations prohibit full access to the work, which hinders the work.

[Problems to be solved by the device]

 The present invention has been made in order to solve the above-mentioned conventional problems. The purpose of the present invention is to suspend a plate material that is extremely easy to install and can be quickly and stably and safely lifted. To provide a jig.

[0006]

[Means for Solving the Problems]

 The hanging jig for plate material of the present invention comprises a lower hanging hook having an insertion rod inserted into a hole at a lower end of a hollow plate, an upper hook having an insertion rod inserted into a hole at an upper end of a hollow plate, and a tip. A part is connected to the lower suspension hook, and a suspending wire which is hooked on the upper hook midway and whose upper end is connected to a lifting means such as a crane is characterized in that. The lower hanging hook and the upper hook may have a long body.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes an extruded cement molded plate as a hollow plate, which has a plurality of holes 1a in the longitudinal direction as shown in FIG. Reference numeral 2 is a lower suspension hook, 3 is an upper hook, and 4 is, for example, a vinyl-coated suspension wire.

A lower suspension hook 2 is attached to the lower end of the extruded cement molding plate 1, and an upper hook 3 is attached to the upper end.

As shown in FIG. 3, the lower suspension hook 2 is composed of a lower suspension hook body 2a, an insertion rod 2b and a suspension ring 2c. The lower end of the insertion rod 2b is integrally connected to the lower suspension hook main body 2a with a predetermined gap maintained therebetween. A suspension ring 2c is attached to the upper end of the lower suspension hook body 2a, and the tip of the suspension wire 4 is coupled to the suspension ring 2c.

As shown in FIG. 4, the upper hook 3 is composed of an upper hook body 3a, an insertion rod 3b, and a hook ring 3c. The insertion rod 3b is integrally connected at its upper ends with a predetermined gap maintained between the insertion rod 3b and the upper hook body 3a. A hook ring 3c is attached to the outer surface of the upper hook body 3a. The hanging wire 4 is inserted through the hanging ring 3c.

Since the hoisting jig of the present embodiment is constructed as described above, in order to hoist the hollow plates 1 using this, as shown in FIG. 7, first, they are stacked in a substantially horizontal state. Insert the insertion rod 2b of the lower suspension hook 2 into the hole 1a at the lower end of the hollow plate 1, and insert the insertion rod 3c of the upper hook 3 into the hole 1a at the upper end.

Subsequently, when the upper end portion of the suspension wire 4 is pulled up by an appropriate hoisting device such as a crane (not shown), the hollow plate 1 is erected from a solid line state to a virtual line state and then hoisted. . The load of the hollow plate 1 at the time of hoisting is borne by the lower hanging hook 2 and the hanging wire 4, and the upper hook 3 has a function of preventing the hollow plate 1 from falling over and supporting it when the hollow plate 1 is raised.

In the above embodiment, two hooks 2 and 3 are set on each of the upper and lower ends of the hollow plate 1, but the jig of the present invention is not limited to this. As shown in FIG. 8, an elongated lower hanging hook 5 and an upper hook 6 may be used. In this embodiment, 5a and 6a are hook bodies, 5b and 6b are insertion rods, 5c is a suspension ring, and 6c is an insertion ring.

[0014]

[Effect of device]

 1) By simply inserting the lower rod hook insertion rod and the upper hook insertion rod into the holes in the upper and lower ends of the hollow plate, it is possible to set extremely easily and quickly. 2) Since the insertion rod is inserted into the hole of the hollow plate, each hook can be set reliably and stably, and as a result, the hollow plate can be safely lifted. 3) The hollow plate can be erected easily and safely. 4) It can be attached in close contact with the adjacent hollow plate. 5) An inexpensive jig can be provided.
