Next, a method of using the anchor bolt fixing device constructed as described above will be described. As shown in FIG. 8 to FIG. 9, in the operation work in the foundation work, the water threads 31 in the left-right direction and the water threads 32 in the front-rear direction are stretched in a direction orthogonal to each other, and the water threads 31, 32 are placed at predetermined positions in accordance with the water threads 31, 32. A temporary formwork (internal formwork) 33 is constructed. In the present embodiment, the direction parallel to the water thread 31 in the left-right direction is the X direction, and the direction parallel to the water thread 32 in the front-rear direction is the Y direction. As shown in FIG. 8, the temporary form 33 is constructed by arranging the frame plate members 34 facing each other. The frame plate member 34 is extended in the X direction or the Y direction (front and back or left and right directions) so as to form a predetermined foundation, and is completely surrounded so that the cast concrete as a whole does not leak. The anchor bolt 39 is embedded in the basic concrete that is placed in the temporary form 33 to fix the column base metal fitting 41 shown in FIG. Therefore, since the anchor bolt 39 serves as a reference for the position when the pillar is erected, the temporary form 33 is made in accordance with the water threads 31, 32.
It is required to be accurately arranged in a predetermined position in the X direction and the Y direction inside.

First, description will be made on the case of installing at a corner portion (upper corner position in FIGS. 8 to 10). The worker attaches the anchor bolt fixture to the frame plate member 34 of the temporary form 33 at a predetermined position where the anchor bolt 39 is embedded. At this time, the operator first applies the second side plate 15 of the fixture body 11 to the inner wall surface of the frame plate member 34. At this stage, the straight line P is parallel to the water thread 31. Here, depending on the case, a backing plate is provided between the frame plate member 34 and the second side plate 15 to adjust the amount of advance of the fixture main body 11, and the first side plate 14
The left and right first V-shaped grooves 20 formed on the upper end of are matched with the water threads 31 in the X direction (a pad plate is not provided in the present embodiment). When the matching is completed, the positions in the Y direction are further aligned, and the fixture main body 11 is fixed to the frame plate member 34 by the clamp 38 (FIG. 9). Then, FIG.
Further, as shown in FIG. 7, the suspension plate 12 is set on the bottom plate 13 of the fixture body 11 such that both guide cylinders 27 thereof are oriented in the left-right direction. As shown in FIG. 10, when the suspension plate 12 is set, the centers of the two guide cylinders 27 are arranged at the lower positions that coincide with the water threads 31 in the left-right direction. Then, in this state, the two anchor bolts 39 are inserted into the guide cylinder 27 and fixed by the thumbscrew 28 at a predetermined vertical position. In addition, the anchor bolt 39
In this embodiment, the object to be fixed by the anchor bolt 39 is not the base but the column base metal fitting 41 of the type fixed by the two anchor bolts 39 as shown in FIG. 11 in this embodiment. Since the outer diameter of the anchor bolt 39 is substantially the same as the inner diameter of the guide cylinder 27, the center of the guide cylinder 27 and the center of the anchor bolt 39 substantially coincide with each other. As a result, the centers of the two left and right anchor bolts 39 substantially coincide with the water thread 31.

Next, as shown in FIGS. 8 to 10, description will be given of the case of installing in a T-shaped portion projecting inward in the shape of a jetty. At the T-shaped portion, unlike the above-mentioned corner portion, two front and rear anchor bolts 39 are embedded at this position. The worker performs the same work as above, and the straight line P and the thread 31
Try to match and. Then, the second V groove 21 formed at the upper end of the second side plate 15 is matched with the water thread 32 in the Y direction. As a result, the straight line Q is aligned with the water thread 32 in the Y direction, and the front and rear two anchor bolts 3
The center of 9 will be arrange | positioned in the downward position which corresponds to the water thread 31. When the matching is completed, the fixture main body 11 is fixed to the frame plate member 32 by the clamp 38 (FIG. 9). Next, as shown in FIGS. 6 and 7, the suspension plate 12 is mounted on the bottom plate 13 of the fixture main body 11 and the guide tubes 2
Set so that 7 faces forward and backward. As shown in FIG. 10, when the hanging plate 12 is set,
The center of each of the two guide cylinders 27 is arranged below the water thread 36 in the front-rear direction. Then, in this state, the two anchor bolts 39 are inserted into the guide cylinder 27 and fixed by the thumbscrew 28 at a predetermined vertical position. Anchor bolt 3
Since the outer diameter of 9 is substantially the same as the inner diameter of the guide cylinder 27, the center of the guide cylinder 27 and the center of the anchor bolt 39 substantially coincide with each other. As a result, the center of the anchor bolt 39 substantially coincides with the water thread 32.

As described above, the following effects can be obtained by configuring as in this embodiment. (1) In the anchor bolt fixing tool arranged in the corner portion, the first V groove 20 on the left and right of the first side plate 14 and the water thread 31
Aligning with each other makes it easier to determine the exact position of the anchor bolt 39 whose water thread 31 and its center must match. Further, by arranging in this manner, the centers of the two anchor bolts 39 both coincide with the water thread 31. In this way, since the two anchor bolts 39 are also aligned with the water thread 31, the mounting bracket 41 can be set accurately along the X and Y directions, and by extension, the four directions of the pillar standing on the mounting bracket 41 can be set. It can be set exactly along the X and Y directions. (2) In the anchor bolt fixing device arranged in the T-shaped portion, by aligning the second V groove 21 of the second side plate 15 with the water thread 32, the water thread is located at the center position of the front and rear two anchor bolts 39. It becomes possible to arrange so that there is 32. (3) If only the fixing device main body 11 is fixed first, the accurate position of the anchor bolt 39 is automatically determined by setting the suspension plate 12 as a separate body later. The work efficiency is improved because the work of attaching only the fixture main body 11 to the frame plate member 34 may be performed. (4) The hanging plate 12 is set by the engaging projections 29 so as not to be laterally displaced from the fixture body 11, and
By setting, the exact position of the anchor bolt 39 is also naturally determined, so that the working efficiency is improved. (5) The engaging projection 29 of the hanging plate 12 engages the through hole 22b so as to guide the hanging plate 12 to the two guide cylinders 27.
Can be set in the fixture body 11 so that they are lined up in the left-right direction (that is, along the water thread 31), and then the hanging plate 12 is rotated by 90 degrees so that it is engaged with the through hole 22a this time. The book guide cylinders 27 are engaged so as to be aligned in the front-rear direction (that is, along the water threads 32). That is, the suspension plate 12 can be engaged with the fixture main body 11 at positions rotated by 90 degrees so as not to be laterally displaced, and at those rotation positions, two guide tubes are provided along the X direction or the Y direction. 27 can be easily arranged.

Further, the above embodiment can be modified and implemented as follows. -In the above-mentioned embodiment, the first on the left and right of the first side plate 14
Only one of the V-grooves 20 may be provided. In addition, FIG.
The first side plate 14 may be provided upright on only one of the left and right sides as shown in FIG. Even with such a configuration, since the first side plate 14 and the second side plate 15 are orthogonal to each other and parallel to the straight line P, the second side plate 15 can be surface-mounted on the inner wall surface of the frame plate member 34. Since the straight line P naturally becomes parallel to the water thread 31, adjustment is performed by interposing a backing plate between the second side plate 15 and the frame plate member 34, and the straight line P and the water thread 31 are made to coincide with each other. The center of the bolt 39 can be aligned with the water thread 31. In the above-described embodiment, the first V groove 20 or the second V groove 21 is formed as the first or second mark. However, other than this, the point is not limited to the V groove as long as it is a mark that can be compared with the water threads 31 and 32. -In the said embodiment, the 2nd V groove 21 of the 2nd side plate 15 is not necessary. In the above embodiment, the two through hole groups 23 are formed on the upper surface of the bottom plate 13 of the fixture body 11, but the number may be one or three or more. -In the above embodiment, the fixture body 11 and the hanging plate 1
Although 2 is configured as a separate body, these may be integrated. Although the hanging plate 12 is given as an example of the hanging portion, other shapes may be used. The guide cylinder 27 is formed on the hanging plate 12, but it is not always necessary. -The method of using the above anchor bolt fixing tool is an example.
For example, the anchor bolt 39 may be attached to the suspension plate 12 first, and then the suspension plate 12 may be set on the fixture body 11. The lateral deviation prevention means may have a configuration other than the above. The shape of the temporary mold 33 is not limited to the above. Further, although the clamp 38 is used as the fixing means of the fixing tool main body 11 in the above, a means such as a screw fixing may be appropriately used together by utilizing the screw hole 19 of the fixing tool main body 11. Others The present invention can be freely modified and implemented in a mode without departing from the spirit of the invention.
