Installation of the anchor bolt to the foundation, for example, before casting concrete in a concrete foundation formwork, place the anchor bolt in a predetermined position so that its lower part is buried in the cast concrete, Next, concrete is cast in a formwork.

[0003] The present applicant has already developed an anchor bolt support as shown in FIG. 8 for arranging the anchor bolt at a predetermined position before placing concrete. This conventional anchor bolt support 1 includes two form members 3, 3, 3
A rectangular support plate 4 that is placed in a state of being bridged thereon
Regulating portions 5 and 5 formed by cutting out a part of the support plate 4 and bending the cut-out portions at both end portions of the support plate 4;
A support plate plate 6 that stands substantially vertically at the center of the support plate, an extension plate portion 7 that extends from the upper end of the support plate portion 6 in parallel with the support plate 4, and the support plate 4 and the extension plate. It comprises insertion holes 8 and 9 respectively provided at positions where the portions 7 overlap each other, and a nut 11 screwed to the upper end of the anchor bolt 10.

[0004] The method of using the anchor bolt support 1 is as follows. First, the upper end of the anchor bolt 10 is inserted into the insertion holes 8 and 9 of the support plate 4 and the extension plate 7, and the upper end of the anchor bolt 10 is inserted into the upper end of the anchor bolt 10. The nut 11 is screwed. As a result, the nut 11 larger than the insertion holes 8 and 9 is prevented from coming off,
The anchor bolt 10 is attached to the anchor bolt support 1. In addition, the lower end of the anchor bolt 10 is buried in the concrete, and is in a state where the diameter is expanded in order to cope with an upward pulling force, and the lower end of the anchor bolt 10 has insertion holes 8 and 9. Can not be inserted.

[0005] The insertion holes 8 and 9 have an anchor bolt 1 so that the diameter thereof can be easily inserted.
While it is considerably larger than the diameter of 0,
An arc-shaped concave portion having a diameter substantially the same as the diameter of the anchor bolt 10 is formed in a part thereof. After the anchor bolt 10 is inserted through the insertion holes 8 and 9, the anchor bolt 1 is inserted into the concave portion.
By engaging 0, the position of the anchor bolt 10 is determined.

Next, a ruler tape 12 is arranged on the upper surface of the foundation form 2 along the length direction of the cloth foundation. In addition, the ruler tape 12 has notches 12a formed at predetermined intervals on one side edge thereof, and the anchor bolts 10 are aligned with the notches 12a so that the anchor bolts 10 are arranged. It can be arranged at a predetermined position on the foundation.

[0007] Then, as described above, the anchor bolt 10

In this case, the anchor bolt support 1 The substantial weight and size of the anchor bolts 10 are increased by the anchor bolts 10, and the anchor bolts 10 rattle with respect to the anchor bolts 1 so that the operability of the anchor bolts 1 is poor. When the anchor bolt support 1 is to be removed after the concrete has been poured into the foundation form 2 and the concrete has hardened, the nut 11 at the upper end of the anchor bolt 10 having the lower end fixed to the foundation.
It is necessary to release the screwing of the anchor bolts and completely remove them, and to move the anchor bolt support 1 upward to remove the anchor bolts 10, and to support the anchor bolts from all the anchor bolts 10 arranged on the foundation of one house. It took time to remove the tool 1.

The distance between the regulating portions 5 provided at both ends of the support plate 4 of the anchor bolt support 1 is
Since the distance between the two form members 2 and 2 of the base form 1 is corresponding to the distance between the two form members 2 and 2 depending on the foundation, the distance between the regulating portions 5 and 5 is different. It is necessary to prepare different anchor bolt supports 1. That is, one anchor bolt support 1 cannot cope with foundations having different thicknesses. In addition, the thickness of the foundation may be different between a two-story house and a three-story house, for example, and the thickness of the foundation of the three-story house is thicker than the thickness of the foundation of the two-story house. May be. Also,
Even in one house, the thickness of the foundation surrounding the bathroom may be thinner than the other foundations.

It is possible to adopt a configuration in which the anchor bolt can be inserted between the contact portion and the pressing means from the side of the anchor bolt support. And, if it is configured so that the anchor bolt can be inserted from the side of the anchor bolt support, when installing the anchor bolt support on the base form, after installing the anchor bolt support on the base form, The anchor bolt can be attached to the anchor bolt support. Therefore, the lightweight and compact anchor bolt support before the anchor bolt is attached can be installed at a predetermined position of the base form, so that the anchor bolt support can be easily installed on the base form. The attachment of the anchor bolt to the foundation using the anchor bolt support can be facilitated.

According to the anchor bolt support according to the second aspect of the present invention, the contact restricting plate is disposed at a predetermined angle with respect to the support plate, and a predetermined angle is formed from the contact portion of the angle restricting means. If they are arranged at a distance, the contact restricting plate is brought into contact with the side surface of one of the base form members, thereby disposing the anchor bolts in contact with the contact portions of the angle restricting means with respect to one of the base form members. Can be determined. In addition, since the contact regulating plate comes into contact with only one base form material, the other base form material is supported by the anchor bolt support with respect to one base form material. It is only necessary to be located within the range from the distance of adding the concrete thickness necessary to support the anchor bolt to the distance to the anchor bolt to the distance that the support plate can be bridged, one base form material and the other An anchor bolt support can be used even if the distance from the base form material is different. That is, even when forming foundations having different thicknesses, it is possible to cope with anchor bolt supports of the same standard.

According to the anchor bolt support of the third aspect of the present invention, there is provided a notch portion into which the anchor bolt can be simultaneously inserted from the side into the support plate and the extension plate. Since the predetermined position of the inner edge of each notch of the extension plate is a contact portion of the angle regulating means, the predetermined position of the inner edge of the notch provided on the support plate, The anchor bolt can be set at a predetermined angle, for example, vertical, by contacting the anchor bolt at two positions above and below a predetermined position of the inner edge of the cutout provided. Also, since the notch allows the anchor bolt to be inserted from the side, the anchor bolt is installed from the side of the anchor bolt support after the anchor bolt support is installed on the foundation form as described above. The support can be set at the position of the contact portion at the predetermined position of the notch.

According to the anchor bolt support of the fourth aspect of the present invention, the anchor bolt can be clamped by pressing the anchor bolt against the recess of the cutout portion with the screw body. In addition, since the anchor bolt can be inserted into the notch from the side of the anchor bolt support and clamped, install the anchor bolt support on the base formwork and then attach the anchor bolt to the anchor bolt support. Can be.
