[0010]

The above-described conventional attachment plate 90 has the following problems. First,
A problem in the case where the anchor bolt is used in the self-standing anchoring device shown in FIG. 30 will be described. After fixing the four anchor bolts to the lower attachment plate 90a and the fixing plates 105 and 106 with nuts, the upper ends of the anchor bolts must be inserted into the four bolt holes of the upper attachment plate 90b. In this case, if the diameter of the anchor bolt is small and the weight per anchor bolt is about ten and several kilograms, the handling is easy, but the diameter of the anchor bolt becomes large,
If the weight per anchor bolt is several tens of kilograms, the anchor bolt itself becomes difficult to handle, and the weight of the auxiliary plate 90b increases, so that it is difficult to insert each anchor bolt into the bolt hole of the upper auxiliary plate 90b. It was a task that required skill and labor. In particular, as the number of anchor bolts increases to eight, twelve, and sixteen, it becomes more difficult to insert the bolts into the auxiliary plate. Further, as the weight of the anchor bolt increases, the weight of the nut also increases, and when the nut is screwed after the upper attachment plate 90b is installed, there is a danger that the nut may fall and cause injury. Was dangerous.

Next, problems in the case shown in FIG. 31 will be described. In the case of FIG. 31, since the upper attachment plate 90b, the lower attachment plate 90a, and the fixing plate are fixed to the frame 104, when setting the anchor bolt, first, the lower end side of the anchor bolt is inserted into the bolt hole of the upper attachment plate 90b. After inserting the nut, screw the nut 108,
Next, it is necessary to insert the lower end portion of the anchor bolt into the bolt hole of the lower attachment plate 90a and screw the nut 109, which makes the operation complicated and increases the number of operation steps.

Further, when the weight of the anchor bolt becomes heavy, heavy machinery is often used, and it becomes very difficult to insert the anchor bolt into the two bolt holes of the upper and lower attachment plates. In particular, the number of anchor bolts is 8, 12
As the number of books increases to 16, the workability and cost both worsen. Further, in the case where the anchor bolts are suspended and set with wires while the anchor frame 104 is placed horizontally, after inserting the lower end of the anchor bolts into the upper attachment plate 90b, the wires are temporarily replaced and the lower attachment plate 90a is replaced. Must be inserted into
There was a problem that the cost was not good.

In these methods, since it is necessary to insert the anchor bolt into the bolt hole of the upper attachment plate 90b, the size must be larger than the diameter of the anchor bolt by 0.5 mm or more. For this reason,
There is play due to the difference in diameter. Since the position of the anchor bolt shifts due to this play, it is necessary to fix the anchor bolt to the auxiliary plate after setting the anchor bolt. As this fixing method, since the anchor bolt cannot be welded and fixed, there is a method in which the thread length of the anchor bolt is increased and the anchor bolt is fixed with a nut, but the cost is increased accordingly.

The present invention has been made to solve such a problem, and an object of the present invention is to provide an anchor bolt fixing auxiliary plate which can easily set an anchor bolt and is excellent in safety. .

[0015]

According to the present invention, there is provided an anchor bolt fixing plate for positioning an anchor bolt by engaging the anchor bolt when the anchor bolt is set in an anchor bolt fixing device. ,
The engaging portion with the anchor bolt is constituted by a notch portion into which the anchor bolt can be fitted from the side, and a stopper for preventing the anchor bolt from being detached in a state where the anchor bolt is fitted into the notch portion. Things.

Further, the shape of the notch is a semi-ellipse having a circular arc with which the anchor bolt comes into contact.

Further, the opening side of the cutout portion is formed so as to expand toward the end.
