[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for measuring an anchor bolt mainly used for a partition foundation.

[0002]

2. Description of the Related Art Anchor bolts for mounting building frames and independent columns are buried at the time of foundation concrete casting. Attachment becomes impossible, or the whole is distorted. In this case, anchor bolts shall be installed in the formwork with the anchor bolts fixed to the formwork for placing the foundation concrete. It is defined in manuals.

[0003]

However, in the case where the peripheral foundations are all at the same height, they can be installed with a certain degree of accuracy, but in places where the peripheral foundations are lower than the peripheral foundations, such as partition foundations. However, the height of the anchor bolt is also reduced accordingly. For example, even if a water thread is stretched between the outer peripheral foundations, it is difficult to obtain the accuracy due to the low height, and the position accuracy is often not confirmed. For this reason, there is a problem in that there are many poor construction accuracy such as pillars. An object of the present invention is to provide a measuring jig capable of easily measuring a center deviation of an anchor bolt.

[0004]

In order to solve the above problems, in the present invention, a water thread (21) stretched between outer peripheral foundations on a jig body (1) installed on a top end face (5) of the foundation. An indicator rod (2) having a length up to near the height of the vehicle is erected. The reference rod (2) is provided with reference portions (3a) and (3b) for aligning the position with the water thread (21), and the reference portion (3a)
An index (12) indicating a reference position from (3b) to the anchor bolt core is provided, and the deviation of the anchor bolt core is measured from the index (12).

[0005]

[Function] Install the anchor bolt on the top of the foundation so that the upper end of the anchor bolt penetrates the opening. Slide in the direction
Measure the misalignment between the index and the anchor bolt core.

[0006]

In FIG. 1, (1) is a jig body obtained by bending a metal plate into a rectangular lid shape. The indicator rod (2) of the present invention is integrally fixed and erected. On the upper end surface of the indicator rod (2), there are formed cross-shaped references (3a) and (3b) as reference portions of the present invention for locking the water thread. Further, anchor bolts (6) (6) projecting upward from the top end surface (5) of the concrete foundation (4) are attached to both sides of the indicator rod (2) in the longitudinal direction of the foundation. Openings (7) and (7) for projecting upward through the upper surface are formed. These openings (7)
In (7), the jig body (1) is formed in a long hole shape in the base longitudinal direction with respect to the anchor bolt (6) so that the jig body (1) can slide in the base longitudinal direction.

On the upper surface of the jig body (1), an index (9) indicating the position of the water thread is formed so as to match the reference groove (3a) formed in a direction perpendicular to the longitudinal direction of the foundation (4). ) Is formed. A scale (8) having a predetermined length is provided on both sides of the index (9) in the basic longitudinal direction. In addition,
The index (9) is also formed continuously on the side wall surface (10) of the jig body (1). Furthermore, for this index (9),
From the index (9), a second index (12) indicating the position of the bolt core of the anchor bolt (6) is moved from the upper surface of the jig body (1) to the side wall surface (10) on the side of the opening (7). It is provided continuously over the straddle.

[0010] A level (13) for measuring horizontality in the X direction and the Y direction is attached to the upper surface of the jig body (1). Further, on the side wall surface (14) perpendicular to the longitudinal direction of the base of the jig body (1), a third index (15) indicating the position of the anchor bolt core with respect to the width direction of the base top end surface (5) is provided. Have been.

FIG. 2 shows a measuring method using the above jig. The foundation (4) shown in FIG. 1 is a partition foundation as shown in FIG. 2, and firstly, the upper surface of the outer peripheral foundation (17) in a direction parallel to the partition foundation (4) is similarly designated. Another measuring jig (1) with the rod (18)
9) Install. At this time, the anchor bolt (20) projecting from the top end face of the outer peripheral foundation (17) is fixed to the jig (19).
In such a state, the indicator rod (18) is installed at a position corresponding to the reference line of the building. The jigs (19) of the outer peripheral foundation are installed as two pairs at positions facing each other, and a water thread (21) is stretched between the upper ends of the indicator rods (18). Then, as shown in FIG. 1 on the top end face of the partition foundation (4).
The jig (16) of the present invention is set in the same manner as described above.

With the jig (16) of the present invention installed as described above, the partition base (5) is adjusted so that the reference groove (3a) at the upper end of the indicator rod (2) matches the water thread (21). Is slid along the longitudinal direction, and in this state, whether the bolt core of the anchor bolt (6) is displaced with respect to the index (12) or, if so, how much the scale is displaced ( 8) Measure in. If the deviation is, for example, 3 mm or more, the anchor bolt (6)
Adjust the center misalignment. Further, as shown in FIG. 1, the partition base (4) is attached to the top end face (5) for adjustment of the misalignment.
A mark (22) indicating the position of the anchor bolt (6) is marked with black ink or the like, and a mark (23) indicating a reference position corresponding to the water thread (21) is also marked.

Further, in order to measure the center deviation in the direction perpendicular to the longitudinal direction of the partition base (5) of the anchor bolt (6),
A jig (19) similar to the above is installed on the anchor bolt (25) of the outer peripheral foundation (17) in the longitudinal extension direction of the partition foundation (5), and a water thread stretched on the jig (19) (2
Based on 4), the measurement is performed by aligning the water thread (24) with the groove (3b) along the longitudinal direction of the base at the upper end of the indicator rod (2). In this case, in a state where the jig body (1) is installed at an accurate position in the width direction of the partition foundation (5), the third index provided on the side surface (14) of the jig body (1) in the longitudinal direction. In contrast to (15), the width of the jig body (1) is adjusted to a predetermined reference length, and therefore, the escape ink (26) is applied along the side wall surface in the width direction. hand,
In the meantime, blackout can be performed in the direction of the partition foundation (5).

[0012]

[Effects of the Invention] As described above, the jig of the present invention is installed on the partition foundation, and the indicator rod is fitted to the water thread stretched between the outer peripheral foundations. Alignment can be accurately measured.
Therefore, if there is any misalignment, the partition foundation is adjusted, and the independent columns etc. attached to the anchor bolts of this partition foundation can be accurately installed, greatly reducing the failure of the columns and other construction accuracy. There is an effect that can be.
