Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for securely obtaining the position of anchor bolts embedded in a foundation of a house.

[0002]

2. Description of the Related Art Conventionally, a technique relating to a jig for confirming the accuracy of the position of an anchor bolt embedded in the foundation of a partition and correcting it to an accurate position has been filed. For example, Japanese Patent Application No. 3-226495 and Japanese Patent Application No. 3-226.
It is like No. 71575.

The prior art is shown in FIGS. 7, 8, 9, and 10. That is, in the basics of housing,
The portion of the outer wall portion foundation B is one step higher than the portion of the partition portion foundation A. That is, the foundation A of the partition section is one step lower. Therefore, the position of the tip of the anchor bolt 1 is also lower than that of the anchor bolt 13 of the outer wall foundation B, and the anchor bolt 1 of the partition A foundation A is lower. However, when measuring whether the position of the anchor bolt 1 is in a normal position in this state, the water thread M is moved from the anchor bolt 13 of the outer wall base B to the anchor bolt 13 of the outer wall base B at the other end. Since it is stretched on the upper part of the anchor bolt 1, the water thread and the position of the tip of the anchor bolt 1 are separated from each other, and it is difficult to determine whether or not the anchor bolt 1 is in the proper position.

Further, the anchor bolt 1 is erected in the frame metal foam 9 for the foundation A of the partition part, and the anchor bolt plate 10 is made of the frame metal so that the anchor bolt 1 does not move even if concrete flows in in this state. Although it was fixed between the foams 9, since the partition foundation A is lower than the outer wall foundation B, the position of the tip of the anchor bolt 1 is lower than the upper end of the frame metal foam 9,
The anchor bolt plate 10 had a mounting surface that was the upper surface of the frame metal foam 9, and the portion that held the anchor bolt 1 was a concave shape that had a recess protruding into the frame metal foam 9.

With such a concave structure, as shown in FIG. 9, the anchor bolt plate 10 is bent to lose its regular width, or the center of the framed metal foam 9 is displaced from the center of the water thread. When the anchor bolt plate 10 is present, the anchor bolt plate 10 cannot be moved to the left and right, which makes adjustment of this position difficult. Further, since the anchor bolt plate 10 and the anchor bolt 1 are supported only by inserting the upper body of the anchor bolt 1 into the anchor bolt plate 10, when the poured concrete touches the anchor bolt 1 as shown in FIG. To
There was also a problem that the position of the anchor bolt 1 changed.

[0006]

DISCLOSURE OF THE INVENTION The present invention is to accurately obtain the position of the anchor bolt of the foundation A of the partition part of the basic part of the house, which has a structure lower than that of the house outer wall part foundation B. . Further, by making the connection state between the anchor fixing plate 5 and the anchor bolt 1 firm, it is possible to prevent the position of the anchor bolt 1 from being moved by the concrete that has flowed in. Further, when the entire position of the framed metal foam 9 is displaced from the center of the water thread, the position of the anchor bolt 1 is adjusted by adjusting the positional relationship between the anchor fixing plate 5 and the guide plate 4. It is configured so that the position of the water thread is exactly the same.

[0007]

The problems to be solved by the present invention are as described above. Next, the means for solving the problems will be described. That is, the additional bolt 2 is fastened to the tip of the anchor bolt 1, and the tip of the additional bolt 2 is
The guide tube 4 is fitted inside a guide tube 3 protruding downward, and the guide plate 4 is attached to the frame metal form 9
It is fixed to.

An anchor fixing plate 5 is interposed between the guide plate 4 and the frame metal foam 9, and an adjusting guide 7 portion is formed between the guide plate 4 and the anchor fixing plate 5. The position of the anchor bolt 1 can be adjusted by moving the guide plate 4 with respect to.

[0009]

[Operation] Next, the operation will be described. That is, the anchor bolt 1
Since the add-on bolt 2 is fastened to the tip of the guide plate, the tip of the add-on bolt 2 is fitted inside the guide tube 3 projecting downward from the guide plate 4, and the guide plate 4 is fixed to the frame metal foam 9. As in the conventional case, when the anchor bolt 1 is in a weakly fixed state, there is a problem in that the anchor bolt 1 is changed in its mounting position due to the flow of concrete, but this problem is solved. I was able to do it. That is, the anchor bolt 1 is screwed to the replenishment bolt 2, the replenishment bolt 2 is fitted to the guide cylinder 3, and the guide cylinder 3 is attached to the guide plate 4.
Since it is fixed to the anchor fixing plate 5 through the anchor bolt 1, the anchor bolt 1 is no longer pushed by the concrete flow.

An anchor fixing plate 5 is interposed between the guide plate 4 and the frame metal foam 9, and an adjusting guide 7 portion is formed between the guide plate 4 and the anchor fixing plate 5. On the other hand, since the position of the anchor bolt 1 with respect to the water thread can be adjusted by moving the guide plate 4, the overall position of the frame metal form 9 is deviated, and the anchor bolt 1
Even if is placed on the center line of the frame metal form 9,
When the anchor bolt 1 is loosened from the water thread M, the fixing bolt 8 is loosened, and the anchor bolt 1 and the guide plate 4 are moved together with the anchor ruler 6, whereby the anchor bolt 1
Was able to move to the center of the thread M.
