Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an inking tool used for inking (marking) at a predetermined interval in, for example, a building work such as a reinforcing bar work or a steel frame work.
[0002]
[Prior art]
Conventionally, as shown in FIG. 4, in the case of floor arrangement (FIG. (A)), column arrangement (FIG. (B)), beam arrangement (FIG. 4). C)), in the case of a steel stud dowel ((D) in the figure), for example, worker A uses a scale or the like to support it with one hand of worker A, and with a free hand, such as chalk Marking is performed on pillars, floors, etc. using marking members.
[0003]
[Problems to be solved by the invention]
However, since both hands of the worker A are used, particularly when marking on a pillar or the like, the work is performed at a high place, and the work in a state where both hands are blocked is unstable, and there is a risk of falling or falling. Further, in work such as floor reinforcement, standing and sitting are repeated, and worker A becomes heavy labor. The pitch marking tool according to the present invention is proposed to solve such a problem.
[0004]
[Means for Solving the Problems]
The gist for solving the above problems of the pitch marking jig according to the present invention is as follows: an arm, a rotating body rotatably supported by the arm, and a circle of the rotating body provided on a side surface of the rotating body. A pitch set quick reference table formed by adding position marks divided into a plurality of circumferences, and a pitch set quick reference table arranged along the radial direction at equal intervals in the circumferential direction on the outer peripheral portion of the rotating body . And a marking member protruding from the outer peripheral surface of the rotating body corresponding to a desired position mark .
[0005]
The marking member includes a tip portion that can be freely protruded and projected on an outer peripheral surface of the rotating body; and a guide frame for preventing the wheel from being removed on a side surface of the rotating body.
[0006]
According to the pitch marking tool according to the present invention, marking can be performed simply by rolling the rotating body to the marking surface. Further, when the marking pitch changes, the marking member can be arbitrarily protruded or buried from the outer peripheral surface of the rotating body. Furthermore, by providing the guide frame on the rotating body, for example, the rotating body rotating during marking does not escape from the reinforcing bar.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Next, the pitch marking tool according to the present invention will be described with reference to the drawings.
[0008]
As shown in FIG. 1, the configuration of the pitch marking tool 1 according to the present invention includes a telescopic arm 2 and a rotation made of metal or synthetic resin that is rotatably supported at the tip of the arm 2. It comprises a body 3 and marking members 4 disposed along the radial direction at equal intervals in the circumferential direction on the outer periphery of the rotating body 3.
[0009]
The arm 2 is made of stainless steel, for example, and can be expanded and contracted in stages. The distal end portion of the arm 2 is bent in the orthogonal direction, which serves as a rotation axis, and the rotating body 3 is rotatably mounted. The arm 2 is provided with an ink tank 5 made of, for example, synthetic resin, which can be refilled and is detachable. As shown in FIG. 1, the lower end of the ink tank 5 is disposed close to the outer peripheral surface of the rotating body 3.
[0010]
The marking member 4 disposed inside the rotating body 3 has a tip portion that can freely protrude and appear on the outer peripheral surface of the rotating body 3. For this, an elastic material (coil spring, torsion spring, rubber, sponge, etc.) that constantly urges outward is disposed at the rear end of the marking member 4 in the recess that houses the marking member 4. When the marking member 4 is buried from the outer peripheral surface of the rotating body against the urging force of the elastic material, a lock device is provided for positioning at the buried position.
[0011]
As shown in FIG. 1, a pitch set quick reference table 7 is provided on the side surface of the rotating body 3. In this quick reference table 7, the circumference is divided into 6 (outside in the figure), the circumference is divided into 4 (middle in the figure), and the circumference is divided into 3 (inside in the figure) It is represented by adding a mark 7a.
[0012]
Therefore, for example, if the circumference of the rotating body 3 is 600 mm (diameter: about 191 mm), the marking pitch can correspond to three pitches of 100 mm, 150 mm, and 200 mm. Therefore, the operator may project the tip portion 4a of the marking member 4 at the position of the position mark 7a in the quick reference table 7 corresponding to the required pitch from the outer peripheral surface of the rotating body.
[0013]
The leading end 4a of the marking member 4 is made of, for example, rubber, sponge, or the like. On the other hand, the leading end 5a of the ink tank 5 that is in sliding contact with the leading end 4a is such that ink oozes appropriately. It is a mesh.
[0014]
In addition, when this pitch marking tool 1 is used for a long and narrow reinforcing bar, in order to roll the rotating body 3 stably, as shown in FIG. A guide frame 6 for preventing annulus is provided. The guide frame 6 is a thin disk made of metal or hard plastic.
[0015]
In order to use the pitch marking jig 1 formed in this way, for example, as shown in FIG. 3, the arm 2 is set to an appropriate length with respect to the marking object, and the operator A can use one hand. Grab the arm and roll the rotating body 3. Thereby, the marking member 4 of the rotating body 3 marks at predetermined intervals. When it is necessary to change the pitch of the mark, the marking member 4 is appropriately projected and retracted on the outer peripheral surface of the rotating body, and the rotating body 3 is rolled to perform marking.
[0016]
In order to mark an elongated object such as a reinforcing bar, the guide frame 6 is attached to the rotating body 3, and the reinforcing bar or the like is sandwiched between the both sides of the guide frame 6 (in a loose fit state). In these marking operations, the worker A can use one hand, so one hand is freed, and the safety of the worker A is ensured.
[0017]
【The invention's effect】
As described above, the pitch marking jig according to the present invention includes an arm, a rotating body rotatably supported by the arm, and a plurality of circumferences of the rotating body provided on the side surface of the rotating body. Pitch set quick reference table with position marks divided into types, and a desired position of the pitch set quick reference table arranged along the radial direction at equal intervals in the circumferential direction on the outer periphery of the rotating body Since it consists of a marking member that protrudes from the outer peripheral surface of the rotating body corresponding to the mark , one-handed operation is possible, the work efficiency is greatly improved, and the operator's safety is also ensured. It plays.
[0018]
The marking member can be adapted to various pitches because the tip portion of the marking member can be projected and retracted on the outer peripheral surface of the rotating body. Furthermore, since a guide frame for preventing the wheel from being removed is provided on the side surface of the rotating body, the rotating body is not removed from the elongated marking object such as a reinforcing bar, and a reliable marking operation can be performed. it can.
