Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor bolt neck protrusion measuring tool capable of easily and reliably measuring the protrusion size of an anchor bolt protruding from a top end of a foundation in a comfortable posture.

[0002]

2. Description of the Related Art As is well known, an anchor bolt for firmly building a skeleton is embedded in the foundation, and the neck of the anchor bolt is projected from the top end of the foundation. The anchor bolts can be embedded by, for example, temporarily installing a suspension support fitting that suspends the anchor bolt on the top end of the foundation formwork, and temporarily suspending the anchor bolt's neck to this suspension support fitting to form a suspension support state. This is done by pouring ready-mixed concrete into the interior and removing the above-mentioned suspension fitting after hardening of the concrete.

By the way, the neck length of the anchor bolt protruding from the top of the foundation, that is, the protruding length of the neck of the anchor bolt, is a reference length of, for example, about 35 mm to 45 mm in order to connect with the body in the best condition. However, when the anchor bolt is embedded in the foundation by the above-mentioned construction, the protruding size of the neck of the anchor bolt becomes longer than its standard length or vice versa. Sometimes. In this way, when the protruding size of the anchor bolt neck does not satisfy the standard length, especially when the protruding size of the anchor bolt neck is longer than the standard length, the anchor bolt is not sufficiently embedded in the foundation. As a result, there arises a problem that the drawing strength and the like are reduced. In addition, there is also a problem in that when the frame is built on the foundation, it may interfere with the fastening of the horizontal binding bolts of the frame assembly and the like, so that sufficient tightening cannot be performed. On the contrary, if the protruding length of the neck of the anchor bolt is shorter than the reference length, the nut tightening when fastening with the shaft assembly will be insufficient, and there will be a problem that the skeleton cannot be firmly built. Occurs.

In order to prevent these problems from occurring, the protrusion size of the neck of the anchor bolt is previously set to a reference length, that is, an allowable length, which allows the skeleton to be installed on the foundation in the best condition without any trouble. After performing a measurement operation to determine whether or not it is within the range, if the measurement result does not satisfy the allowable range, a correction operation may be performed. Therefore, conventionally, for example, as shown in FIG. 8, when the work of measuring the protruding dimension h of the neck of the anchor bolt C is performed, the worker A
Confirms whether or not the scale 6 such as a pen or a convex is directly applied to the neck of the anchor bolt C in a posture in which the hip is dropped or in a mid-waist or the like and whether the scale 6 is within the allowable range.

[0005]

However, according to the above-mentioned conventional technique, the worker A measures the protruding dimension h of the neck of the anchor bolt C in a posture in which a load is placed on the legs such as a lowered posture or a mid-waist posture. Will be forced to do,
Therefore, there is a problem in that physical fatigue and low back pain are caused to impair health. Further, since the operation of standing and sitting is repeated, the work efficiency is not good, and there is a problem that the visual height of the worker A and the top end level of the neck of the anchor bolt C do not easily match and a measurement error easily occurs. Become.

The present invention solves the above problems and provides an anchor bolt neck protrusion measuring tool which enables an operator to easily and reliably measure the anchor bolt neck protrusion dimension in a comfortable posture. The purpose is to

[0007]

Means for Solving the Problems In order to solve the above-mentioned problems, as a means for solving the problems, according to the present invention, in claim 1, a scale case having both ends open and having a space inside, and a dimensional scale is added to the outer peripheral surface. And a scale having an end cap at one end of a scale body slidably accommodated in the space of the scale case, and one end of the scale case is a mounting portion mounted on the base top end. Together with the other end as a reading line of the dimensional scale of the scale body, further, the other end of the scale body as a neck end of an anchor bolt protruding from the base top end ,
With respect to the other end of the scale case,
The end caps on the ends are removable .

Further, in claim 2, an allowable range mark is added to the outer peripheral surface of the scale main body to show that it is within an allowable range with respect to the protruding size of the neck of the anchor bolt projecting from the base top end. is there.

[0009]

[0010]

With the above structure, in order to measure the protruding size of the neck of the anchor bolt protruding from the top end of the foundation, first, the scale main body is housed in the space of the scale case, and the end cap provided at one end of the scale main body. While still in contact with the end of the scale case, hold the scale case so that it is perpendicular to the top surface of the foundation, and position it above the neck of the anchor bolt protruding from the top edge of the foundation. Let Subsequently, while the scale case is being lowered right below, the neck end provided on one end of the scale main body housed inside the space of the scale case is placed in contact with the top end of the neck end of the anchor bolt. Further, in that state, the scale case is lowered toward the base top end, and the mounting portion at one end of the scale case is mounted on the base top end. At this time, the neck of the anchor bolt enters into the space near the mounting part of the scale case, and the scale body moves upward from the reading line provided at the other end of the scale case only for the protruding dimension of the neck of the anchor bolt. It will be extracted. That is, the end cap provided at one end of the scale body and the reading line provided at the other end of the scale case are separated from each other by the protrusion size of the neck of the anchor bolt. At this point, the protruding size of the neck of the anchor bolt can be measured.As a measuring method, for example, a dimensional scale attached to the outer peripheral surface of the scale body can be used from the end cap at one end of the scale body to the other end. 0 toward the tip of each anchor bolt
In the case of adding from mm, the scale of the scale main body located on the reading line of the scale case is read. In this case, for example, if the protrusion size of the neck of the anchor bolt is 40 mm, the value of the scale of the scale main body located on the reading line of the scale case is 40 mm, and the protrusion size of the neck of the anchor bolt is easy. It is possible to read easily.

When an allowable range mark is added to the outer peripheral surface of the scale main body, for example, the allowable range of the protruding size of the neck of the anchor bolt is set to 35 mm to 45 mm,
When the allowable range mark is added within the range of the 35 mm to 45 mm scale of the scale body, the neck bolt of the above anchor bolt has a protruding size of 40 mm. The scale mark indicates 40 mm, and the allowable range mark of the scale body is located on the reading line of the scale case. As a result, the operator can easily confirm that the protruding size of the neck of the anchor bolt is within the allowable range. On the other hand, when the protruding size of the neck of the anchor bolt is 30 mm or 50 mm, which is outside the allowable range,
The reading line of the scale case is 30mm or 50mm
Although it refers to the value of the dimensional scale such as, the allowable range mark of the scale body comes off without being located on the reading line of the scale case. As a result, the operator can easily confirm that the protruding size of the neck of the anchor bolt does not satisfy the allowable range.

In this way, the neck extension of the anchor bolt is measured, but when the end of the scale case and the end cap at one end of the scale body are detachable, the measurement work is completed. When carrying the tool for measuring the neck of the anchor bolt, attach the end of the scale case and the end cap at one end of the scale body by screwing etc. with the scale body stored inside the space of the scale case. Good to do. By doing so, the scale case and the scale are integrally connected, which is convenient to carry.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In the anchor bolt neck protrusion measuring tool 1 according to the present invention, as shown in FIG. 1, for example, an operator A stands in a neck protrusion dimension h of the anchor bolt C protruding from the base B top end. The scale case 2 and the scale case 2 are used for easy and accurate measurement in a comfortable posture such as, for example, as shown in FIGS.
The scale 3 has a scale body 3a slidably accommodated therein.

The scale case 2 is made of synthetic resin and is relatively thin and lightweight, and is formed into a long tubular shape having an internal space with both ends open. However, the material may be formed of metal such as stainless steel or other material, and the cross-sectional shape is triangular, quadrangular, or other rectangular shape, especially if it has an internal space with both ends open. It may be a shape, a curved surface shape such as an ellipse, or other various shapes, and is not limited. One end of the scale case 2 thus formed, which is to be placed on the top end of the foundation B, is a placing portion 2a. The opening of the placing portion 2a accommodates the neck of the anchor bolt C. As much as possible, it is formed to have a diameter at least larger than the diameter of the tip of the anchor bolt C.
In addition, the other end of the scale case 2 on the opposite side of the mounting portion 2a,
That is, the other end on the side opposite to the side placed on the base B top is
A connection opening 2b is formed which is connected to a scale 3 described later, and an internal thread having a pitch of about 2 to 3 is provided on the inner surface of the connection opening 2b. The opening edge of the connection opening 2b is the reading line r.

As described in detail in FIG. 5, the scale 3 has a scale main body 3a slidably accommodated in the space of the scale case 2 as a main constituent element. One end of the scale case 2, that is, one end located on the side of the connection opening 2b of the scale case 2 is covered and fitted with an end cap 3b, and the other end of the scale body 3a, that is, the mounting of the scale case 2 is performed. At the other end located on the side of the portion 2a, a sealing material that becomes 3c per neck of the anchor bolt C is screwed,

Similar to the scale case 2, the scale body 3a is made of a synthetic resin and is relatively thin and lightweight. Both ends are open to have an internal space. Although it is formed in a long tubular shape with an outer diameter smaller than the inner diameter of, the material may be made of metal such as stainless steel or other materials, and its cross-sectional shape is triangular. The shape is not limited, and the shape may be a rectangular shape such as a quadrangle, a curved shape such as an ellipse, and other shapes. Also in this case, it is preferable to have an internal space for the purpose of reducing the weight, but it is not necessary to have the internal space.

On the outer peripheral surface near the other end of the scale body 3a thus formed, a dimensional scale 4 having a length of about 150 mm in increments of 1 mm or the like is added. As a means for this, the outer peripheral surface of the scale body 2a is engraved, but a sealing material, a metal plate, a synthetic resin plate or the like having the dimensional scale 4 pre-printed thereon is attached to the outer peripheral surface of the scale body 3a. Alternatively, the color may be simply colored with an oil-based coloring material that does not easily disappear. In particular, from the viewpoint of preventing the dimensional scale 4 from disappearing and providing durability, the dimensional scale 4 is attached to the outer peripheral surface of the scale body 3a, and then the dimensional scale 4 is transparent enough to be easily read. The protective seal may be covered. Further, paint or the like may be sprayed instead of the protective seal.

In addition to the size scale 4, an allowable range mark 5 indicating an allowable range of the protrusion size h of the neck of the anchor bolt C may be added at a predetermined position on the outer peripheral surface of the scale body 3a. For example, the protrusion size h of the neck of the anchor bolt C
When the allowable range of is set to a value of 35 mm to 45 mm,
35 mm to 45 m additionally marked on the outer peripheral surface of the scale body 3a
It is made easy for the operator to confirm by adding a mark on the lateral side of the scale 4 up to m. The means for adding the allowable range mark 5 in this case is the same as the above-mentioned dimension scale 4, but the anchor bolt C for each foundation B
When the allowable range of the projected dimension h of the neck is not constant and there is a change in the position where the allowable range mark 5 is added, an adhesive seal that can be easily transferred, a color tool that can be easily erased, etc. It is advisable to add ingenuity, such as by adding in.

The end cap 3b has an insertion space so that the other end of the scale body 3a can be inserted, and the open end 3d is provided with a male screw of about 2 to 3 pitches. Is. In the insertion space of the end cap 3b thus formed, the scale body 3
The other end of a is inserted and both are bonded by an adhesive or screwed together, but in addition, a convex portion is provided on the inner surface of the end cap 3b and the outer peripheral surface of the other end of the scale body 3a. The both may be connected by fitting, for example, by providing a recess or the like, and the connecting means is not limited. Further, the outer shape of the end cap 3b is similar to that of the scale case 2 so as to improve the appearance, but the outer shape of the scale case 2 may be different. In addition, the open end 3d of the end cap 3b directly contacts the connecting opening 2b of the scale case 2 and the scale main body 3
It serves to prevent the drop of a by unnecessarily falling into the scale case 2.

3c per neck of the above anchor bolt C
As the sealing material that becomes, inside the space of the scale case 2,
In particular, a bolt member or the like made of a hard synthetic resin or metal having a size that can be accommodated in the space on the mounting portion 2a side of the scale case 2 may be used. Alternatively, the sealing material may be simply a flat plate and attached to one end of the scale body 3a with an adhesive. In particular, the shape, type, etc. are not limited as long as the neck of the anchor bolt C is a member that can prevent the scale body 3a from entering the space. If the scale body 3a is not tubular or the like and has no internal space, the attachment of the sealing material may be omitted if not necessary. Further, even in the case of the scale main body 3a having the internal space, the sealing material may be omitted similarly when the bottom wall is provided by integral molding so as not to open one end. In these cases, one end of the scale body 3a directly serves as the neck tip 3c of the anchor bolt C.

With respect to the connected state of the constituent members formed in this way, a sealing material is screwed onto one end of the scale body 3a to provide the neck bolt 3c of the anchor bolt C, and
The other end of the scale body 3a is covered and fitted with an end cap 3b, and while the scale body 3a is accommodated in the space of the scale case 2, the male screw of the end cap 3b is inserted into the connecting opening 2b of the scale case 2. The whole is united by being detachably screwed to a female screw. The reason why the whole is made integral in this way is to make it convenient to carry the protrusion measuring tool 1 for the neck of the anchor bolt. Also, in this embodiment, the end cap 3b
The thread cutting end, that is, the opening end portion 3d bears the value of 0 mm at the beginning of the dimension scale.

Next, for example, in a case where the neck protrusion size h of the anchor bolt C protruding from the top end of the foundation B is set to 40 mm, the method of using the anchor bolt neck protrusion measuring tool 1 will be described. While holding the scale case 2 so as not to rotate the shaft, the end cap 3b of the scale body 3a is rotated 2-3 times to release the screwed state of both. Then, after confirming that the scale body 3a is pulled out from the scale case 2, the scale body 3a
The scale case 2 accommodating the above is maintained so as to be perpendicular to the top end surface of the base, and is positioned on the neck of the anchor bolt C protruding from the top end of the base B. Subsequently, while lowering the scale case 2 in that state, the sealing material screwed onto one end of the scale body 3a is brought into contact with the top end of the neck of the anchor bolt C, and the scale case 2 is further lowered to mount the mounting portion. 2a is placed on the top of the base B so as to abut.

Under this condition, for example, as shown in detail in FIG. 6, the entire neck of the anchor bolt C is accommodated in the mounting portion 2a side of the scale case 2. As a result, the protrusion size h of the neck of the anchor bolt C, that is, 4
The scale main body 3a is pulled out from the scale case 2 by an amount corresponding to 0 mm. Specifically, for example, as shown in detail in FIG. 7, the opening end 3d of the end cap 3b fitted to the other end of the scale body 3a, that is, the value 0 mm of the dimension scale 4 is connected to the scale case 2. Only 40 mm, which corresponds to the protruding dimension h of the neck of the anchor bolt C, projects from the opening 2b, that is, the reading line r, and separates.

After that, in a comfortable posture such as the standing posture of the worker A, the visual height i is set on the reading line r provided at the opening end 2b of the scale case 2, and the reading line r of the scale case 2 is set. The 40 mm value on the dimensional scale 4 of the scale main body 3 a located is read to measure the neck extension size h of the anchor bolt C, and the scale main body allowable range mark 5 on the read line r of the scale case 2 is measured.
Check the existence of. As a result, the allowable range mark 5 of the scale body 3a is placed on the reading line r of the scale case 2.
Is located, indicating that the neck protrusion size h of the anchor bolt C is within the allowable range, it can be determined that the application is possible without correcting the neck bolt protrusion of the anchor bolt C. On the other hand, when the allowable range mark 5 of the scale main body 3a is not located on the reading line r of the scale case 2 and the protrusion size h of the neck of the anchor bolt C is out of the allowable range, the anchor bolt C It is possible to determine that the head of the person needs to be modified so that it is within the allowable range to make it applicable.

According to the above procedure, the neck protrusion size h of the anchor bolt C is measured. When the measurement work is completed and the anchor bolt neck protrusion measuring tool 1 is carried, the space of the scale case 2 is measured. With the scale body 3a housed inside, the male screw of the end cap 3b of the scale 3 is screwed into the female screw in the connecting opening 2b of the scale case 2 to integrally connect the scale case 2 and the scale 3 together. It is good to put it. Doing so makes it convenient to carry.

Further, one of the features of the anchor bolt neck protrusion measuring tool 1 is that it enables the measurement work in a comfortable posture such as a standing posture as described above. , Scale case 2 placed on top of foundation B
It is preferable to set the total length of the scale case 2 so that the reading line r of 1 and the visual height i of the worker A in the standing posture are horizontal.

[0028]

In the anchor bolt neck protrusion measuring tool according to the first aspect of the present invention, it is possible to easily and easily maintain a comfortable posture, such as a standing posture, which does not easily bear a burden, without repeatedly performing standing and sitting motions. Since the protruding size of the neck of the anchor bolt protruding from the top end of the foundation can be quickly measured, there is an effect that the work efficiency can be improved without damaging the health of the body. Further, since it is possible to keep the visual height of the worker in a standing posture and the reading line of the scale case for reading the protruding size of the neck of the anchor bolt horizontal, it is possible to eliminate the measurement error and increase the certainty. Also occurs. Further, since the end cap is provided at one end of the scale body, the end cap does not come into contact with the other end of the scale case, and the scale body does not unnecessarily fall out of the space inside the scale case. Furthermore,
Connecting the scale case and scale together
This makes it convenient to carry.

In addition, in the anchor bolt neck protrusion measuring device according to the second aspect, in addition to the above effect, it is easily confirmed whether or not the anchor bolt neck protrusion dimension is within an allowable range. It is possible to further improve the work efficiency.
