Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a curing device that prevents sparks generated during gas cutting of a reinforcing bar at a construction site where the reinforcing bar is used, such as civil engineering and construction work.

[Conventional technology]

Sparks scatter when gas cutting steel bars and steel frames at a construction site, but if these sparks fall and come into contact with combustible materials, a fire may occur, which is dangerous.

Therefore, conventionally, during cutting work, the flammable material is removed assuming the range where the sparks are likely to be scattered, and a fireproof cloth is laid or a surrounding work is surrounded by fireproof cloth.

[Problems to be solved by the device]

In the conventional curing method for setting such a fireproof cloth, it takes a lot of time to prepare for the work, and after the work, it is necessary to clean up dust other than the fireproof cloth.

The object of the present invention is to eliminate the disadvantages of the above-mentioned conventional example, to easily install or remove it at the place where the reinforcing bar should be cut, and to surely capture the sparks and dust that are generated inside the container, and a spark curing device that is easy to clean after the fact. To provide.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention has a first handle,
An opening is provided at a side portion of a portable cylindrical container, and a reinforcing bar holding section composed of a reinforcing bar engaging recess and a bifurcated locking piece at the tip of an arm urged and biased by a spring is provided above and below the opening. The other end of this arm is connected to a hinge on a side portion of the container, and a second grip corresponding to the first grip is provided on the way.

[Action]

According to the present invention, when the second handle is brought closer to the first handle, the arm moves against the spring, and the bifurcated locking piece at the tip of the arm is separated from the engaging recess of the reinforcing bar. A space is formed between the reinforcing bars to be cut.

In this way, when the reinforcing bar is positioned between the engaging recess and the forked locking piece and the second handle is released, the arm is pulled by the spring, and the reinforcing bar is inserted from both sides by the engaging recess and the forked locking piece. A tubular container with the sides sandwiched is attached to this rebar.

In this way, if the reinforcing bar is gas-cut at the opening surface, the sparks and dust generated will be taken into the container through this opening and will not be scattered outside.

After the cutting work is completed, the second handle is brought closer to the first handle again to separate the bifurcated locking piece at the end of the arm from the engaging recess against the spring, and the container is removed from the reinforcing bar. Dust collected in the is discharged from the opening.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a spark curing device of the present invention, FIG. 2 is a plan view of the same as above, and FIG. 3 is a front view of the same, in which 1 is a cylindrical or rectangular metal container. Is.

This container 1 has an opening 2 formed in a side portion formed by a body plate 8,
It is portable and has a U-shaped first handle 3 on the opposite side. The upper and lower portions of the opening 2 are formed with engaging recesses 6 and 6'of curved reinforcing bars at the edges of the top plate 4 and the bottom plate 5, and
A door plate 9 having a narrow width is attached to the opening 2 with a hinge 7 at the side end of the opening 2, and arms 11 and 11 'having a forked locking piece 10 at the top and bottom of the door plate 9 are laterally projected. . The door plate 9 and the arms 11 and 11 'are curved according to the shape of the container 1, and the bifurcated locking piece 10 is inserted into the engaging recesses 6 and 6'of the reinforcing bar to form a sandwiching part of the reinforcing bar. The lengths of the arms 11 and 11 '.

Further, a locking pin 12 is provided in the middle of the arms 11 and 11 ', and the locking pin 12 and the locking pin 13 projecting on the opposite side of the opening 2 of the top plate 4 and the bottom plate 5 are contracted. A coil spring 14 that urges so as to urge the user is stretched.

Further, an L-shaped second handle 15 facing the first handle 3 is provided in the middle of the upper arm 11.

At the side end of the opening 2 opposite to the hinge 7, a spark scattering member 16 by an angled vertical plate was attached.

Next, the usage method will be described.

The arms 11 and 11 'are attracted to the coil spring 14, and the forked locking piece 10 is in contact with the engaging recesses 6 and 6'of the reinforcing bar.

From such a state, if the first handle 3 and the second handle 15 are grasped by the hand and brought close to each other, the arm 11 is resisted against the coil spring 14 and the arm 11 'via the door plate 9. Is moved, the bifurcated locking piece 10 at the arm tip is separated from the engaging recesses 6, 6'of the reinforcing bar, and an interval for inserting the reinforcing bar to be cut is formed therebetween.

As shown by the chain line in FIG. 2, the reinforcing bar 17 already assembled at the site is located between the engaging recesses 6 and 6'and the bifurcating locking piece 10, and the second handle 15 is released as it is. Arm 11,
11 'is attracted, and the engaging recesses 6, 6'and the bifurcated locking piece
The tubular container 1 is attached to the side portions of the reinforcing bar 17 by sandwiching the side portions of the reinforcing bar 17 from both sides at 10.

In this way, the reinforcing bar 17 passes through the inside of the opening 2 through the engaging recesses 6 and 6'arranged vertically, so that the flame is directed to the opening 2 on the surface of the opening 2 and the reinforcing bar 17 is formed. If the gas is cut, the sparks and dust that are generated will come from this opening 2 to the container 1
It is captured by and is not scattered outside.

The reinforcing bar 17 may be vertical or horizontal, and the container 1 is mounted in the direction of the reinforcing bar 17, but in the case of the horizontal direction, the opening 2 is set so as to face upward.

After the cutting work is completed, the first handle 3 is reattached to the second handle 15 again.
The engaging recesses 6 against the spring 14 so that
The bifurcated locking pieces 10 at the tips of the arms 11 and 11 'are separated from 6', the container is removed from the reinforcing bar 17, and the dust accumulated in the container 1 is discharged from the opening 2.

Further, the spark curing device of the present invention can cure not only the cutting of the reinforcing bar but also the sparks at the time of welding.

[Effect of device]

As described above, the spark curing device of the present invention can be easily installed and removed with a single touch at the place where the rebar is to be cut, and the sparks and dust generated during cutting can be reliably taken into the container. Therefore, the fire safety during construction is improved.

Furthermore, it is easy and convenient to clean dust after work.
