Description

Steel bending machine

The invention relates to a steel bar bending machine, especially a steel bar bending machine that bends a steel bar of a predetermined length into a predetermined shape.

At present, a steel cage used in the construction of reinforced concrete is known as shown in FIG. 10, which includes multi-pillar steel bars 70 forming a rectangular ring arrangement, and a plurality of rectangular ring-shaped hoop bars 71 are sleeved on the outer side of the cage. A steel wire binds each hoop reinforcement 71 to the multi-pillar reinforcement 70, and a multi-branched reinforcement 72 is hooked between the column reinforcements 70 on opposite sides, and each tie reinforcement 72 is connected with the steel wire. The column reinforcement 70 and the hoop reinforcement 71 are bound and fixed together.

As shown in Figure 10, Figure 11A and Figure 11B, according to the current law, both ends of the hoop reinforcement 71 must be bent into 135-degree hooks, and the hooks are hooked to the outside of the column reinforcement 70. Each tie reinforcement 72 One end must also be bent into a 135-degree hook portion 721, and the other end of the tie bar 72 must be bent into a 90-degree bent portion 722 at least. The hook portion 721 and the bent portion 722 must reach a predetermined length to make the tie The hook portion 721 at one end of the steel bar 72 can be hooked to the column steel bar 70, and the bending portion 722 at the other end of the tie steel bar 72 is overlapped with the other column steel bar 70 on the opposite side, so that the steel cage has the seismic capacity in compliance with laws and regulations.

The size and shape of the aforementioned tie bars 72 are based on the provisions of the law. One end of the tie bars 72 must be bent into a 135-degree hook 721, and the other end of the tie bar 72 must be bent into a bent portion 722 of at least 90 degrees. The body of 72, the hook portion 721 and the bending portion 722 are all located on a reference plane 720 passing through the center line of the main body of the tie bar 72. Since the hook portion 721 is turned back in the direction of the bending portion 722, the distance between the end of the hook portion 721 and the end of the bending portion 722 is larger than the length between the two columns of steel bars 70 to be connected by the tie bars 72 Therefore, the construction work of connecting the steel bars 72 between the two columns of steel bars 70 is time-consuming and labor-intensive.

Since every building constructed with reinforced concrete must use a large amount of tie bars, it is necessary to improve the problem that the shape of the existing tie bars makes construction difficult. In order to overcome the aforementioned problem that the shape of the existing tie bars poses difficulties in construction, the inventors further designed a new type of tie bars 60A, as shown in Figures 9A and 9B, in which the hook portion 61A of the tie bars 60A maintains compliance with laws and regulations. In addition to the prescribed 135-degree oblique shape, the hook portion 61A is further slanted laterally, so that the hook portion 61A is skewed relative to the reference plane 600 passing through the center line of the main body of the tie bar 60A and the bending portion 62A One angle. As a result, the hook 61A at one end of the tie bar 60A is hooked to the column reinforcement, and the bent section 62A at the other end of the tie bar 60A is overlapped with the other column reinforcement on the opposite side. The hook 61A is used laterally. The skewed structure makes it easy and easy to hook the tie bar 60A between the two columns of steel bars, which effectively improves the assembly efficiency of the tie bar 60A group of tie bar rebars, and can reach the level of the legal tie bar 60A that must be firmly connected to the column bar. Regulations.
