Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an adjustable metal plate of a mounting core and a mounting device for the purpose of adjusting a bolt core and a mounting hole when fixing a metal member to an existing bolt such as an anchor bolt.

[0002]

[Prior art]

 When mounting a metal plate on an existing bolt, if the bolt core and the bolt hole do not match, the bolt hole is opened or a long groove is provided in the metal plate to adjust the mounting position. Further, a technique has been proposed in which a through hole larger than the diameter of the anchor bolt is provided in the metal plate, and the plate body fitted into the anchor bolt is fitted into the through hole and tightened (Japanese Utility Model Publication No. 57-110146).

[0003]

[Problems to be solved by devising]

 Of the above-mentioned conventional techniques, it is a matter of course that a drilling tool is required to newly install a bolt mounting hole, and the tightening force may be weakened or the appearance may be damaged due to the relationship with the existing bolt hole.

When the metal plate is provided with a long groove, adjustment in one direction (direction parallel to the long groove center) is easy, but when the bolt is displaced in the direction perpendicular to the long groove center, the metal plate Since the position of is shifted in any of the X and Y directions, there is a problem that it may not be able to move due to the relationship with other members. There is also a problem that the bolt hole can be made larger than the diameter of the bolt to allow a margin, but it may move as the tightening force decreases. Further, when the perforated disc is fitted, there is a problem that a large number of perforated discs are required.

[0005]

[Means for solving the problem]

 Therefore, this invention provides a circular hole large enough to correspond to the deviation of the bolt core that normally occurs in a metal plate, and has a width equal to or larger than the diameter of the bolt in the circular hole and the diameter of the bolt. The above-mentioned conventional problems were solved by fitting a disk (having a thickness approximately equal to the depth of the through hole) having a groove having a length extending from the larger peripheral edge to the central portion.

For example, by rotating the plate body, the metal plate can be tightened and fixed to the anchor bolt without shifting the metal plate even if the bolt core is displaced in any of the left and right directions.

That is, according to this invention, a circular hole having a diameter larger than the diameter of a mounting bolt to be used is formed in a metal plate body, and the mounting bolt can be inserted into the circular hole from the peripheral edge to the central portion. This is a metal plate with an adjustable mounting core, which has a groove at least longer than the diameter of the mounting bolt, and is fitted with a circular plate of approximately the same thickness as the metal plate.

Next, another invention is to form a circular hole larger than the diameter of a mounting bolt to be used in a metal plate body, and have a width that allows the mounting bolt to be inserted into the circular hole and reach from the peripheral edge to the central portion. A metal plate with a groove that is at least as long as the diameter of the mounting bolt, and that is approximately the same thickness as the metal plate, insert the anchor bolt into the groove, and insert it through a washer. It is an apparatus for mounting a metal plate with an adjustable mounting core, characterized in that it is tightened with a nut. The metal plate body is a metal member having at least a flat plate portion.

In another invention, a circular plate with a groove having a diameter larger than that of the mounting bolt is punched out at a bolt tightening position on the flat surface of the metal plate body, and the remaining protrusion and the peripheral thin wall are further punched to form a circular hole. The metal plate with adjustable mounting core is characterized in that the grooved disk is fitted into the circular hole.

The material of the metal plate may be an aluminum plate, a steel plate, or the like, and can be applied to all brackets and other metal members having a flat plate portion.

Further, it is preferable that the washer has such a size that it can cover the circular hole.

[0012]

[Action]

 According to this invention, the bolt hole of the metal plate is made a relatively large circular hole, and the circular plate provided with the groove having the width and the length larger than the bolt diameter is fitted into the circular hole. By rolling, the anchor bolts can be tightened and fixed without changing the position of the metal plate, regardless of whether the anchor bolts are biased in the front, rear, left, or right directions.

[0013]

Example 1 A case will be described in which a bracket 3 (metal plate) is fastened and fixed to an anchor bolt 2 of concrete 1 with a nut 8.

After the anchor bolt 2 is loosely fitted into the circular hole 4 of the bracket 3, the anchor bolt 2 is fitted into the groove 6 of the circular plate 5, and the circular plate 5 is fitted into the circular hole 4. Then, the washer 7 is fitted to the anchor bolt 2, and the nut 8 is screwed and tightened. In the above description, since the diameter of the circular plate 5 in FIG. 2 is smaller than the diameter of the circular hole 4, the anchor bolt 2 can be fitted into the circular hole 4 at any position. In the figure, 9 is a pillar, and 10 is a screw for fixing the pillar.

In the above embodiment, the bracket 3 can be fixed by tightening even if the anchor bolt 2 of FIG. 2 is displaced from the normal position by S. In this case, the radius of the circular hole X is the radius of S + anchor bolt. Normally, the diameter of the anchor bolt and the maximum deviation of the anchor bolt can be predicted, so that the diameter of the circular hole to be provided in the bracket can be predetermined in terms of design.

[0016]

Second Embodiment As for the circular hole 4 of the bracket 3, as shown in FIG. 4A, a disk 5 with a groove 6 is punched out, and then the projection 11 and the disk 5 with the groove 6 punched out. It can be provided by punching out the thin wall 13 (for example, 0.5 mm) on the peripheral side of the through hole 12 (FIG. 4C). Therefore, since the inner diameter of the circular hole 4 is larger than the outer diameter of the circular plate 5 by, for example, 0.5 mm, the circular plate 5 can be easily fitted.

Further, since the disc 5 can be used as it is, it is possible to remarkably reduce the waste of material, and at the same time, there is an advantage that the material and the thickness are the same.

[0018]

[Effect of device]

 In this invention, a metal plate is provided with a circular hole having a diameter larger than the diameter of the mounting bolt, a circular plate having a groove through which the mounting bolt can be inserted is fitted into the circular hole, and a washer is fitted to the mounting bolt to attach a nut. Since the tightening is done with, there is an effect that even if the position of the existing mounting bolt is deviated from the design, it can be easily fixed without shifting the position of the metal plate.
