Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a clip for binding auxiliary reinforcing bars (commonly known as spiral hoops) that connect main reinforcing bars.

``Prior Art'' Conventionally, relatively thin annular auxiliary reinforcing bars (10 to 13 mmφ) with four corners bent at right angles have been used to connect the main reinforcing bars (see Fig. 8). The auxiliary reinforcing bars are cut to a certain length, arranged in parallel in several strips, and bent by a bender 90 degrees from the state shown in FIG. 3 to the state shown in FIG. 4 to form four corners. During this bending, adjacent auxiliary reinforcing bars that are aligned in parallel tend to separate from each other and create a gap, making it difficult to bend the auxiliary reinforcing bars in an annular shape in the same plane. That was difficult. Therefore, when bending the wires at 90 degrees using a bender, the adjacent auxiliary reinforcing bars are tied together with wires to prevent them from separating, and in that state the wires are bent at 90 degrees using the bender, which takes time and effort and becomes a factor that impedes the efficiency of the bending work. Ta.

``Problems to be solved by the invention'' The purpose of this invention is to obtain a clip that can easily and quickly bind parallel auxiliary reinforcing bars during bending work by a bender and prevent the reinforcing bars from separating. .

``Means for Solving the Problems'' The present invention involves bending both ends of a spring strip whose central portion is bent in an ∧ shape in the same direction toward a plane perpendicular to the plane containing the spring strip to form a hook. It consists of clips for binding reinforcing bars.

``Operation'' Therefore, as shown in Fig. 3, a plurality of cut-to-size reinforcing bars 4 are aligned and supported on a horizontal stand of a bender, and the pins 6
1 before raising one end in the direction of arrow a.
The engaging claws 3, 3 at both ends are hooked on the outside of the reinforcing bars 4, 4 on both sides, which are perpendicular to the direction of the reinforcing bars 4 whose central portions are aligned. In this way, the ∧-shaped bent portion 2 at the center extends linearly, and its restoring force causes the hooks 3, 3 to clamp the plurality of aligned reinforcing bars 4 from both sides. As shown in FIG. 4, even if one end is bent at right angles around the pin 6, the adjacent reinforcing bars 4, 4, which stand upright, are pinched by the claws 3, 3, so the adjacent reinforcing bars 4, 4 do not separate and open, but are bent at right angles while remaining in close contact. As a result of this operation, a plurality of cut-to-size reinforcing bars 4 are aligned and bent into a rectangular ring shape as shown in FIG. 5, and are held in a bundle and packed.

``Example'' As shown in FIG. 1A and FIG.
The hooking claws 3, 3 are formed by being bent in the same direction along a plane orthogonal to the plane containing the latches. One of the engaging pawls 3 is folded back twice as shown in FIG. Also, the other hook 3
is formed in one layer without folding. The ∧-shaped bent part 2 is formed with a coil part 2' having one or two windings as shown in FIG.
It may be folded heavily. As shown in FIG. 2, the engaging claws 3, 3 are curved in an arc shape 3'' in opposite directions,
The tip is slightly bent in the opposite direction. As shown in FIG. 7, the reinforcing bar 4 is formed with an embossed portion 4', and the hooks 3, 3 are hooked on the embossed portion 4' so that the reinforcing bar 4 is not displaced in the longitudinal direction. The number 5 in the figure is the main reinforcement of the building.

``Effects'' Since the present invention is constructed as described above, it is possible to quickly and easily hold several parallel cut-to-size reinforcing bars 4 before bending them at right angles with a bender around the pin 6. , 4 can be prevented from leaving.
