Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is suitable for use when assembling and fixing reinforcing bars in construction foundation work. related to binding devices.

0002

[Conventional technology]

In reinforced concrete construction work, reinforcing bars, which are structural members, are combined. It is being fixed. In this case, the conventional fixing of reinforcing bars is usually a diameter line called a radiused line at the intersection of the reinforcing bars. Bundle and wrap 2 to 4 soft iron wires of about 0.8 mm, and then peel off this smoothed wire. This is done by manually tightening using a fastener called a kamawashi. .

0003

[Problem that the idea aims to solve]

However, the bundling using the smoothed wire described above has the following drawbacks. a. We use soft, smoothed wire with a thin wire diameter so that it can be tightened manually. Because of this, the binding force is weak, and if a large force is applied to the intersection of the reinforcing bars during work, they may become dull. The wire may come undone or break. Therefore, in addition to being dangerous, it is necessary to rebind these defective areas with smoothed wire. This reduces work efficiency. In addition, if re-binding is not performed, the strength of the assembled reinforcing bars decreases. b. Because the smoothed wire is tightened manually using a hammer, it depends on the skill level of the installer. Therefore, variations occur in the degree of tightening, making it difficult to obtain a constant state of binding. c. It is necessary to prepare several different lengths of smoothed wire in advance depending on the thickness of the reinforcing bar. Work efficiency is poor. d. Since the smoothed wire is similar in color to the reinforcing bars, check whether the intersections of the reinforcing bars have already been tied together. is difficult to see. Therefore, it is easy to forget to tie the knot.

0004 On the other hand, reinforcing bars are also firmly fixed by welding, but this Since this method uses fire, it should not be used in tunnels etc. from the viewpoint of fire prevention. I can't do it. This invention was developed in view of the above circumstances, and it is possible to use a certain amount of reinforcement steel for construction foundation work. It is an object of the present invention to provide a binding tool that can be firmly fixed with binding force.

[Means and actions for solving the problem]

In order to achieve the above-mentioned purpose, this invention aims to connect reinforcing bars etc. that are integrally formed with wire. The binding tool includes a pair of winding parts each having a linear part connected to an arcuate part at the tip thereof, and the above-mentioned two winding parts. and a connecting portion that connects the base ends of the linear portions to each other, and the approximately O where the arcuate portions intersect. The tips of the letter-shaped or arcuate portions are spaced apart from each other and are formed in a substantially V-shape. Provides a binding device for reinforcing bars, etc. that has the following characteristics.

[0006] The binding tool of the present invention has an intersection between a plurality of reinforcing bars between both wrapping parts as shown in FIGS. 2 and 4, which will be described later. Attached to the intersection of reinforcing bars by inserting or other methods called sashing After attaching, twist both arcuate parts together using a drill etc. It connects reinforcing bars together. In this case, when binding reinforcing bars with the binding device of the present invention, open both winding parts and use the binding device. Attach it to the intersection of the reinforcing bars, then close both wrapping parts and cross the arcuate parts, then The arc-shaped parts are twisted together using a tightening drill, but the binding tool of this invention The tip of the attachment part is shaped like an arc and the base is shaped like a straight line, so when the wrapped part is closed, it can be shaped like an arc. When the sections are crossed, the tip of the arc-shaped section should be directed toward the tip of the binding tool (the chuck of the drill). direction), so it is easy to attach the drill chuck to the arc-shaped part . In other words, if the entire wrapped portion is arc-shaped, the wrapped portion is closed and the arc-shaped portions are crossed. When inserted, the tip of the arc-shaped part should point toward the proximal end of the binding tool (in the direction of the chuck of the drill). This makes it difficult to attach the chuck, but the strapping tool of this invention With the above configuration, the arc-shaped part is There is no big change in the angle to the chuck, and it is similar to when the entire mounting part is shaped like an arc. There are no inconveniences.

[0007] In addition, since there is a straight part at the base of the wrapped part, reinforcing bars should be inserted between both straight parts. When intersecting both arcuate parts, even if reinforcing bars of various thicknesses are used, it will not be possible to make a straight line. There is always some play in the shape. Therefore, one size tie can be used for various diameters. can bind reinforcing bars.

[0008] The present invention will be explained in more detail below. In the binding tool of the present invention, 1/2 to 1/3 of the length of each winding part is an arc-shaped part, and 1/2 It is preferable that ~2/3 of the length be the straight part. This allows the mounting part mentioned above to The effect of preventing changes in the angle of the arcuate part due to opening and closing is effectively achieved. Ru. In addition, the binding tool of the present invention can be used with a wire having a diameter of 1.2 to 4 mm, especially 2 to 3 mm. It is preferable to form the tube with a large diameter, so that a large breaking load can be obtained. Furthermore, use wire that is a different color from the reinforcing steel, especially galvanized iron wire. is preferred. This makes it easy to visually identify reinforcing bars and ties. This helps prevent forgetting to tie the knots, as it allows you to easily see where the ties are tied. In addition, a bent protrusion may be provided at the center of the connecting portion as shown in the embodiment described later. This allows the winding portion to be opened and closed easily. Note that the size of the invented binding tool is not limited, and can be shaped to an appropriate size depending on the diameter of the reinforcing bar. can be achieved. There are no limitations to the manufacturing method of the binding tool of the present invention, but for example, the wire is formed into a circle and the tip is Examples include a method in which a linear portion is formed by pressing the proximal end after cutting.

【Example】

Next, the present invention will be specifically illustrated by examples, but the present invention is not limited to the following examples. Embodiment 1 FIG. 1 shows an embodiment of the binding tool of the present invention. This binding tool is made of galvanized iron wire with a diameter of 2 to 3 mm. In this binding tool, 1 and 1 are winding parts, respectively. This winding part 1 has a circular arc part 3 integrally connected to the tip of a straight part 2, and the straight part 2 has a length of about 1/2 to 2/3 of the winding part 1, and has a circular The arcuate portion 3 is formed to have a length approximately 1/2 to 1/3 of the wrapped portion 1. In addition, the base ends of both linear parts 2, 2 are integrally connected via a slightly curved connecting part 4, so that the binding device of this example has a substantially O-shape in which the arcuate parts 3, 3 intersect with each other. It is formed. In this case, the arcuate portions 3 intersect so that the one on the right side is in front of you, so that when you twist both the arcuate portions 3 together, you can wind both the arcuate portions clockwise. is now possible. Furthermore, a bending protrusion 5 is formed in the center of the connecting portion 4, and this allows the wrapping portions 1, 1 to be easily opened and closed when attaching the binding device to the reinforcing bars. ing.

0010 When binding reinforcing bars using the binding tool of this example, first, as shown in Figure 2, tie the binding tool. Open and close the tie as appropriate so that the intersection of reinforcing bars A and B is inside both wrapped parts 1 and 1. Attach to A and B. Next, attach a drill chuck to the tips of the arcuate parts 3, 3, and turn the chuck over time. By rotating it about 2 to 3 times in the clockwise direction, both the arcuate parts 3 and 3 are connected to each other. It is something.

Embodiment 2 FIG. 3 shows another embodiment of the binding device of the present invention. The binding tool of this example has the same winding parts 1, 1 as the binding tool shown in FIG. They are formed in a substantially V-shape that is slightly spaced apart. In this case, both the winding parts 1, 1 are connected in such a way that the arcuate part on the right side is at the front, and the arcuate part on the left side is at the back. Both arcuate parts 3, 3 can be turned clockwise when twisting them together. When binding reinforcing bars using the binding device of this example, first open and close the binding device as appropriate and tie the reinforcing bars so that the intersection of reinforcing bars A and B enters both wrapped portions 1 and 1, as shown in Fig. 4. Attach the tools to reinforcing bars A and B. Next, after closing the winding parts 1, 1 and intersecting the arcuate parts 2, 2 as shown in FIG. 2, the two arcuate parts 3, 3 are connected to each other in the same manner as the binding device of FIG. 1. It is something. In the above embodiment, an example was shown in which reinforcing bars were bound using the binding device of the present invention, but the binding device of the present invention can also be used for binding other arbitrary objects.
