Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a PC plate erecting jig used for erecting a PC plate, which is arranged as an outer wall surface of a building, for example.

[0002]

[Background of device]

 The work of raising a PC board temporarily placed at a construction site or the like is usually performed by attaching a wire extending from a crane to the upper end of the PC board and winding the wire. By the way, the PC board built up in this way is a heavy object that weighs several tons, and it can be rotated around its lower end contacting the ground as a fulcrum until it reaches an upright position. Excessive force may be applied to the parts, causing damage.

At present, when raising a PC board, a mat is laid in advance at a position where the lower end of the PC board comes into contact with the ground, and the load on the lower end is reduced to protect the PC board. However, this method is troublesome to install and remove the mat, and the mat is damaged in a short period of time, requiring frequent replacement.

In particular, when the PC board on which the granite is pasted is built, the granite may be damaged even if the work using the mat is performed, and the commercial value is lost. We had to proceed carefully, and it took a lot of time and effort.

[Disclosure of device]

 The purpose of the present invention is to effectively prevent damage to the lower end of the PC board during the work of raising the PC board, and to make the work of raising the PC board easy and quick, and with excellent workability. It is to provide a PC board erection jig. An object of the present invention is a PC plate erection jig that is used by attaching it to an end of the PC plate when the PC plate is erected, and a recess for locating the end of the PC plate. And a guide part having a smooth curved surface part for guiding the rising motion of the PC plate.

That is, the PC plate erecting jig is attached to the lower end portion of the PC plate by fitting the recess of the PC plate erecting jig, and the PC plate is erected and the PC plate is raised. The tool guide portion (curved surface) rises up as a fulcrum, and therefore no unreasonable force acts on the PC board, so there is no problem that the PC board is damaged by the erecting work.

Moreover, since the PC board erecting jig allows the PC board to be erected extremely safely and smoothly, the work can be simplified and the work time can be greatly shortened. , PC board construction work can be saved. In order to prevent one end of the PC plate from directly hitting the inner surface of the recess of the PC plate raising jig, it is preferable that the bottom surface of the recess be provided with a protrusion, for example. It is possible to support the appropriate position of the granite, and for example, when the PC board with the granite affixed to the surface is erected, the granite part can be surely prevented from being damaged and the safety is high.

If a cushioning material is provided so that one end of the PC plate does not directly contact the inner surface of the recess of the PC plate erecting jig, for example, a PC plate erecting operation in which granite is pasted on the surface At that time, the granite portion can be surely prevented from being damaged, and the safety is further enhanced. Further, if the concave portion is provided with a flange for holding the PC plate, the portion of the concave portion that comes into contact with the PC plate wall surface becomes wider than the lateral dimension of the concave portion. It comes into contact with the area, improving the stability during installation.

【Example】

 1 to 8 show an embodiment of a PC board erecting jig according to the present invention. FIG. 1 is an external perspective view of the PC board erecting jig, and FIG. 2 is a PC board erecting jig. Side view of the tool, FIG. 3 is a front view of the PC plate erecting jig, FIG. 4 is a rear view of the PC plate erecting jig, and FIG. 5 is a side view showing a state where the PC plate erecting jig is attached to the PC plate. 6 and 8 are side views showing the work of raising the PC board.

In each drawing, 1 is a PC plate raising jig body portion (hereinafter referred to as a jig body portion), 2 and 3 are body portion side plates constituting the jig body portion 1, 4 is a PC plate raising Main body bottom plates 5a and 5c, which serve as guides for the jig, are main body inner plates, and 5b are main body inner bottom plates. That is, the jig main body 1 is configured so that the lower end of the PC plate can be positioned in the recess formed by the main body inner plates 5a and 5c and the main body inner bottom plate 5b.

It should be noted that the main body inner side plate 5c is made wider than the jig main body 1 so that the end of the main body side inner plate 5c can function as a flange (flame). As a result, the contact area with the PC board is increased, and the stability is improved. In addition, the portion of the jig body 1 where the body bottom plate 4 is provided has a gentle curved surface shape as shown in FIG. 2 and the like so that the PC board can be smoothly erected.

Reference numeral 6 denotes a hard rubber plate attached to the body inner plate 5c, and the lateral dimension of the hard rubber plate 6 is wider than that of the body inner plate 5c. Reference numeral 7 denotes a convex portion formed by welding a square pipe of a predetermined size to the inner bottom plate 5b of the main body portion. This convex portion 7 is used when the granite stone is used as the PC inner plate 5b. It is provided to prevent contact.

Reference numeral 8 is a handle welded to the jig main body 1, 9 is a bolt penetrating the main body inner plate 5a, 10 is a nut welded to the main body inner plate 5a and screwed with the bolt 9, and 11 is a bolt. It is a pressing plate attached to the tip of the boot 9. The bolt 9, the nut 10 and the pressing plate 11 constitute a fixing mechanism for the PC plate raising jig. Reference numeral 12 denotes a PC plate, and a granulated stone 13 that has been subjected to main polishing is attached to the outer wall side, and the lower end portion of the outer wall has the granite 13 attached as shown in FIG. The sides are designed to be somewhat longer.

Reference numeral 14 is a lifting jig attached to the upper end of the PC board 12 when the PC board 12 is lifted by a crane, 15 is a wire extending from the crane, 16 is a shackle, and 17 is when the PC board 12 is laid on the ground. This is the mounting table used. The PC board raising jig of the present invention constructed as described above is attached to the PC board 12 as shown in FIG. That is, the hard rubber plate 6 is brought into contact with the granite 13 on the surface of the PC plate 12, the convex portion 7 is brought into contact with the concrete portion at the lower end portion of the PC plate 12, and the bolt 9 is further rotated to fix the pressing plate 11. Press down on the back of the PC board 12 to fix it.

At this time, since the granite 13 is present away from the main body inner bottom plate 5b, there is no fear of damaging the granite 13. Next, a PC board raising operation using the PC board raising jig of the present invention will be described with reference to FIGS. In the present embodiment, the case where the PC board with the granite is affixed will be described, but the work content is the same for the PC board without the granite affixed.

First, as described above, the PC plate erecting jig is attached to the PC plate temporarily placed in the state as shown in FIG. 6, and the lifting jig 14 is attached to the upper end portion of the PC plate. Then, the shackle 16 provided at the tip of the wire 15 is connected to the hoisting jig 14, and the wire 15 is wound up. As a result, the PC board 12 is gradually raised around the lower end as a fulcrum, as shown in FIG. 7, but the lower end of the PC board 12 is lifted up by a PC board raising jig so that it looks like a small lawyer. The PC board 12 does not have an excessive force when it is built up.

Then, as shown in FIG. 8, the PC board erection jig is removed after the PC board 12 is completely upright and ground. As described above, according to the PC plate erecting jig of the present invention, the lower end portion of the PC plate can be extremely protected and effectively protected. Particularly, in the case of a PC plate on which granite is stuck, There are no damage accidents that would lose value.

Moreover, since the work for mounting and removing the PC plate erecting jig is minimal, it is possible to realize a great labor saving compared to the work using the conventional cushioning mat, and the erecting work is unnecessary. Since it is not necessary to carefully perform the work, the work can be performed quickly and the working time can be shortened.
