Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high rigidity grating reinforcing section connecting bar forming apparatus,

The present invention relates to a high rigidity grating reinforcement section connecting bar forming apparatus and a method thereof, and more particularly to the assembly section and the high rigidity so that the reinforcing section connecting bar used for high rigidity grating can be coupled to the assembly groove of the compartment bearing bar. An apparatus and method for forming a high rigidity grating reinforcing section connecting bar for continuously and automatically forming a reinforcing section connecting bar having a bent portion to provide.

Generally, a grating is widely used as a cover of a rainwater drainage channel installed in a road, a park, a playground, a residential complex, a subway, etc., and functions to prevent various kinds of dirt such as fallen leaves from flowing into a drain And a ventilation duct of a subway to perform a ventilation function, and is generally formed of a plurality of rectangular gratings.

These gratings are mainly made of steel to ensure rigidity, and in some cases, stainless steel or plated products may be used to prevent rusting.

Generally, a grating is formed by a plurality of parallel arranged gratings spaced apart at regular intervals

A pair of flat plates attached to both ends of the bearing bar so that the bearing bars are interconnected with each other, and a plurality of cross bars arranged to be perpendicular to the bearing bars on the upper side of the bearing bars so that the bearing bars are not twisted by a load .

The bearing bar and the cross bar are arranged in a lattice-like structure to form a plurality of holes through which rainwater is introduced.

However, the conventional general grating as described above has a problem that the safety of the pedestrian is not taken into consideration at all because its main purpose is to secure a drainage function.

Accordingly, in the case of a grating installed on the road, it is pointed out that a safety accident occurs because women's high heels fall into the hole. In the case of steel gratings installed in parks or schools, the risk of such safety accidents increases further.

In particular, many people who use the park use bicycles, inline skates, or the like. However, according to the conventional steel grating structure, safety incidents in which wheels of a bicycle or inline skates fall into a through hole of a grating, have.

For example, when a child jumps into a hole in a steel grating, the child gets a bruise due to the grating of the steel material. In addition, people who are weak or old people who are uncomfortable are sometimes slipped by holes in the steel grating.

Also, in the case of infants, because of their small foot, they may fall out of the hole in the steel grating. In addition, the wheel of the stroller carrying the infant may be caught in the hole of the grating, making traveling difficult.

In order to solve this problem, a grating has been proposed in which a support plate is formed below a steel grating hole so as to reduce the size of the steel grating through-hole or to prevent women's high heels from falling out.

However, the steel grating having such a structure has a problem that it is difficult to manufacture and the manufacturing cost becomes high.

In addition, the conventional steel grating is fundamentally slippery because the material is formed of steel, and in particular, when the frost falls or snow accumulates in the winter season, the pedestrian slides and becomes more likely to be accidentally damaged.

Basically, the steel material is slippery because it has a smooth surface. If the frost falls or the ice is frozen here, the surface becomes very dangerous. Particularly, when the gratings installed in the parks become so dangerous, the likelihood that people who exercise in the park will be more likely to be injured becomes more severe.

A conventional specific technique is disclosed in Utility Model Registration No. 0328159. The grating may be formed by welding a frame frame and a bearing bar such that the upper side of the bearing frame is divided into a vertical direction or a horizontal direction so that the upper surface of the bearing frame is horizontal. A cross bar formed so as to be continuously bent in a " V "type and a" T " shape is inserted between the frame and the bearing bar so that the frame frame and the bearing bar are aligned horizontally. As shown in Fig.

However, it is very cumbersome and difficult to match the crossbar height to the frame and bearing bar during this welding process. In addition, since the cross bar is fixed and supported only by welding, there are many welding points required and its supporting force is insufficient, which is not stable. If the welding portion falls, the function is lost. There will be defects that do not exist.

As described in the patent registration no. 1072537 (registered on October 10, 2011), the cross bar has a first protrusion and a first protrusion from the inlet side where the strip member is introduced toward the outlet from which the strip member is discharged, A lower bending member that is alternately and repeatedly formed and has a narrower gap between the first projecting portion and the first projecting portion and a greater difference in height between the first projecting portion and the first recessed portion from the entrance side to the exit side; An upper bending member corresponding to the first projection and formed with a second recessed portion for mating with the first projection and formed with a second protrusion corresponding to the first recessed groove and mating with the first recessed groove; And a reciprocating movement part reciprocating the upper folding member with respect to the lower folding member, the strip member moving between the lower folding member and the upper folding member is bent while being moved toward the outlet from the inlet side, And the angle of bending is increased.

However, in such a grating support member manufacturing apparatus, the angle of the concavo-convex shape is gradually formed on the pair of bending members so as to be gradually close to the finished product, and then the material is automatically fed from the inlet side to form a "W" But it is difficult to adjust the supply length or control the speed by the continuous operation, and it is necessary to cut to a desired length after molding. .
