Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a binding tool for binding a large number of reinforcing wire nets or reinforcing bars to be embedded in a concrete structure with binding wires for the purpose of transportation or the like.

[0002]

[Prior art]

 Conventionally, to bind wire nets or reinforcing bars for concrete structures with wire, after binding wire nets or reinforcing bars with wire, both ends of the wire are screwed with pliers or other tool, and the wire is fastened. The method of tightening was adopted.

[0003]

[Problems to be solved by the device]

 However, in such a method, the work is troublesome, and in addition, a lot of manpower and time are required.

In view of the above points, an object of the present invention is to provide a binding tool having a new structure, which can bind a wire net, a reinforcing bar, and the like with good workability.

[0005]

[Means for Solving the Problems]

 The tying device (5) according to the present invention has been devised to achieve the above-mentioned object, and includes a screw rod (1) for rotation having a plurality of thread grooves (8) and a screw rod (1). The hook (2) provided at the tip, the cylindrical gripping body (3) mounted on the screw rod (1), and the inner surface of the gripping body (3) are held and the screw rod (1) It consists of a plurality of rolling balls (9), each of which is arranged in the thread groove (8).

The screw rod (1) is usually made of steel, but it may be made of hard synthetic resin. The length of the screw rod (1) is about 35 to 45 cm, which is convenient. However, the length is not limited to this range. The thread groove (8) of the screw rod (1) has about 3 to 6, preferably 4 threads. The thread pitch of the threaded rod (1) is, for example, about 0.8 to 1.5 cm in the case of a threaded rod having a length of 40 cm. This range is not limited either. Each thread groove (8) is preferably formed in a concave arc shape in cross section.

The hook (2) is integrally fixed to the tip of the screw rod (1). The shape of the hook (2) is not particularly limited, but a C-shaped one is usually used.

The length of the grip body (3) is about 5 to 10 cm, and the material of the grip body (3) is wood, metal, synthetic resin or the like.

The plurality of rolling balls (9) held on the grip body (3) are usually made of metal, the number of which corresponds to the number of threads of the thread groove (8) of the screw rod (1). There is. The radius of the rolling ball (9) preferably approximately matches the radius of the concave arc of the thread groove (8). The rolling ball (9) is preferably held rotatably with respect to the gripper (3).

[0010]

[Action]

 When performing the binding work using the binding tool (5) according to the present invention, after binding the wire nets and reinforcing bars for concrete structures with the wire (4), the binding tool (5) is attached to both ends of the wire (4). Through the hook (2) of the screw rod (1), and grasp the grip body (3) located at the tip of the screw rod (1) non-rotatably with both hands or one hand, and pull it from the tip of the screw rod (1). Pull to the rear end. As a result, the screw rod (1) is rotated with respect to the fixed grip body (3), and both ends of the wire (4) are twisted together. Thus, the binding work is performed.

[0011]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

1, 5 and 6, a binding device (5) according to the present invention comprises a screw rod (1) for rotation, a hook (2) provided at the tip of the screw rod (1), It consists of a cylindrical gripping body (3) mounted on the screw rod (1) and a plurality of rolling balls (9) held on the inner surface of the gripping body (3).

The screw rod (1) is made of steel, and its length is about 40 cm. The thread groove (8) of the screw rod (1) has four threads. The thread pitch of the threaded rod (1) is about 1 cm. Each thread groove (8) is formed in a concave arc shape in cross section.

The C-shaped hook (2) is integrally fixed to the tip of the screw rod (1).

The length of the cylindrical grip (3) is about 8 cm, and the material of the grip (3) is wood. A metal guide piece (10) is attached to the inner surface of the rear end of the grip body (3).

The plurality of rolling balls (9) held on the grip body (3) are made of metal, and the number of them is equal to the number of threads of the screw groove (8) of the screw rod (1). There are four. The large-diameter concave portion on the inner surface of the tip of the grip body (3) is provided with a ball holding piece (11) having four concave portions (12) on the inner surface at equal intervals and a donut plate (14) at the rear end thereof. Each of these recesses (12) is fitted with a rolling ball (9). Then, by fixing the tip flange portion (17) of the ball holding piece (11) to the tip surface of the gripping portion (3) with a screw (15), the four rolling balls (9) are It is rotatably held in (11). The radius of the rolling ball (9) approximately matches the radius of the concave arc of the thread groove (8).

Next, a binding work procedure will be described.

A large number of binding wires (4) having loop portions (6) at both ends shown in FIG. 2 are prepared. The closure of the loop part (6) is made by welding, but is not limited thereto. Then, as shown in FIG. 3, the wire mesh (7) for a large number of stacked concrete structures is bundled with the wire (4), and then the hooks (6) of the ties are attached to both end loops (6) of the wire. 2), hold the grip body (3) located at the tip of the screw rod (1) non-rotatably with one hand, and pull it from the tip to the rear end of the screw rod (1). As a result, the screw rod (1) is rotated with respect to the fixed grip body (3), both ends of the wire are twisted together, and the binding work is performed.

FIG. 7 shows another example of binding. In this example, a large number of double wires (13) folded back in a hairpin shape are prepared. After bundling a large number of rod-shaped steel materials (16) with a wire (13), insert the hooks (2) of the tying tool through the joints at both ends of the wire, and place it at the tip of the screw rod (1). Grasp (3) non-rotatably with one hand and pull it from the tip to the rear of the screw rod (1). As a result, the screw rod (1) is rotated with respect to the fixed grip body (3), both ends of the wire are twisted together, and the binding work is performed.

[0020]

[Effect of device]

 The binding device according to the present invention comprises a screw rod (1) for rotation, a hook (2) provided at the tip of the screw rod (1), and a cylindrical gripping body fitted on the screw rod (1). (3) and a plurality of rolling balls (9) held on the inner surface of the grip body (3), so that the loops at both ends of the wire bundled with wire mesh, steel rod, etc. Pass the hook (2) through and hold the grip body (3) located at the tip of the screw rod (1) non-rotatably, and pull it from the tip of the screw rod (1) to the rear end. By this, the screw rod (1) can be rotated with respect to the fixed grip body (3), and both ends of the wire can be twisted together. In this way, binding work such as wire netting can be reliably performed by a simple operation.
