Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a measuring jig for measuring and inspecting the size of a core ink stamped on the top surface of a concrete foundation of a house or the like.

[0002]

[Prior art]

 4 and 5 show a conventional method for measuring a concrete foundation. For example, when measuring the length between the core ink (21) (21) between the corners of the foundation (22), first install the L-shaped jig (23) as shown in the figure on one corner. The tip of the tape (28) of the tape measure is hooked on the pin (24) of the jig, and the scale of the tape corresponding to the end of the core ink (21) is read at the other corner.

In the above, as shown in FIG. 5, the jig (23) has a plurality of anchor bolts (25), (25) formed with bolt holes (26) which are fitted to each other in a fitting manner. (26) Positioning is done by passing the upper ends of the anchor bolts (25) and (25) through (26). At this time, the inner edge (27) of the jig (23) coincides with the core ink (21), and in this state, the starting point of the scale of the tape (28) hooked on the pin (24) is It is aligned with the starting point (29) of the core ink (21), so that on the opposite side the dimensions can be measured simply by reading the scale corresponding to the end of the core ink (21) as above. I am doing it.

[0004]

[Problems to be solved by the device]

 As described above, conventionally, by inserting the anchor bolt (25) into the bolt hole (26) of the jig (23), the inner end edge (27) of the jig (23) is replaced by the core ink (21). ), The starting point of the scale of the tape (28) hooked on the pin (24) coincides with the starting point (29) of the core ink (21) in the measuring direction. This is the case where the relative position between the anchor bolt (25) and the core ink (21) is at a precisely determined position, and if the anchor bolt (25) and the core ink (21) are There is an error in the dimension (in this case, the position of the anchor bolt (25) will be corrected later according to the core ink (21)), and the core ink (21a ), The starting point of the scale of the tape (28) could not be installed at such an accurate position, which made the measurement difficult.

The present invention solves such a conventional problem, passes the anchor bolt through the bolt hole of the jig, installs the jig on the foundation, and hooks the tip portion of the tape to the jig. Even if the distance between the anchor bolt and the core ink is not within the specified range in the measurement, the starting point of the scale of the tape hooked on the jig should be accurately set to the starting point of the core ink. The purpose is to provide a jig for measurement that can be installed.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, according to the present invention, an anchor bolt protruding from the foundation is projected on a jig body which is installed on the top end surface of the foundation and has a latching portion for latching the tip of the measuring scale tape. A bolt hole is formed to allow the anchor bolt to project upward from the peripheral portion of the anchor bolt hole. It is characterized in that it is mounted via a connecting member, and the jig body is tightened and fixed to the base top end surface by this nut.

[0007]

[Action]

 In the above configuration, if the anchor bolt hole is made larger than the diameter of the anchor bolt inserted therethrough so that a gap is created between them, the jig is displaced within the range of the gap and The starting point of the scale to be hooked can be aligned so as to match the starting point of the core ink to be measured, and the jig is fixed in the correct position by screwing the nut onto the anchor bolt. Can be retained. Further, since the nut is connected to the jig side via a flexible member such as a spring, the nut is not lost, and the flexible member prevents the anchor bolt from being used as described above. The position can be freely moved and screwed.

[0008]

【Example】

 In FIG. 1, (1) is an L-shaped jig main body formed along the corner portion of the base top end as in the conventional case. Similarly to the above, bolt holes (3), (3) ... Are formed so as to match the positions of the anchor bolts (2). A cylindrical protrusion (4) is integrally fixed to the upper surface of the jig body (1) so as to surround the anchor bolt hole (3) so as to project upward. (5) is a coil spring connecting member that is loosely fitted in the cylindrical protrusion (4), and is a cylinder screwed to the upper end of the connecting member (5) at the upper end of the anchor bolt (2). The lower ends of the nuts (6) are connected. The upper end of the cylindrical protrusion (4) is expanded outward to hold the connecting member (5) so that it cannot easily come off. Further, an operating pin (7) for rotating the nut (6) is horizontally projected on the outer periphery of the tubular nut (6).

As shown in FIG. 3, the anchor bolt hole (3) of the jig body (1) has a larger diameter than the outer diameter of the anchor bolt (2) inserted through the anchor bolt hole (3). A gap (8) is formed with the outer peripheral surface. That is, the jig body (1) is not inserted into the anchor bolt (2) without a gap as in the conventional case, but the jig body (1) is horizontally displaced within the range of the gap (3). It can be installed.

In the vicinity of the inner corner of the jig body (1), a latching pin (11) for latching the starting point of the measuring tape (10) is projected upwardly, as in the conventional case. ing. The latch pin (11) is stamped on the foundation (12) with respect to the inner edges (9) and (9) of the jig body (1). When the core ink (13) (13) is aligned, the starting point of the scale of the measuring tape (10) hooked on this pin (11) corresponds to the starting point of the above-mentioned core ink (13) in the measuring direction. It has become.

At that time, if the positions of the anchor bolt (2) and the core ink (13) are not within the determined range, the inner edge (9) and the core ink (13) are separated by 1 as shown in FIG. Even if it is displaced, move it in the direction of the arrow in the figure so that the inner edge (9) of the jig body (1) matches the core ink (13) within the gap (8). In this state, when the nut (6) is screwed onto the upper end of the anchor bolt (2) and tightened, the jig main body (1) is attached to the top end surface of the foundation (12) via the cylindrical protrusion (4). Since the jig body (1) is pressed against and is fixed by tightening, the jig body (1) does not move during measurement, and the dimension can be accurately measured.

Further, even when the jig body (1) is moved in the horizontal direction as described above, the connecting member (5) holding the tubular nut (6) is similar to the spring of the embodiment. Since it has the flexibility to move in the horizontal direction, it is possible to flexibly cope with the movement of such a position, and by being connected by the connecting member (5). Never lose the tubular nut (6). In this embodiment, a spring is used as such a flexible connecting member (5), but a bellows structure or another one may be used as long as it has a similar function.

[0013]

[Effect of device]

 As described above, according to the present invention, even when the dimensions of the anchor bolt protruding to the top end of the foundation and the core ink struck on the foundation are not within the allowable range, the bolt hole of the jig body is By inserting the anchor bolts into the jig and moving the jig body, the starting point of the scale of the tape hooked to the jig body can be made to correspond to the starting point of the core ink to be measured. In such a case, there is an effect that it is possible to easily measure the core black, which was difficult to measure. Further, since the nut for fixing the jig body to the foundation side is connected by a flexible connecting member such as a spring, there is no inconvenience that the nut is lost during work or transportation.
