Bonding Bands {COUPLING BAND}

The present invention relates to a binding band that performs a circular fastener function, and more particularly, when the surface of a circular structure such as a pipe or a columnar structure is surrounded by interior or finishing materials, the member is closely fixed to the structure. The present invention relates to a thin band-shaped binding band.

Binding bands are called steel bands when they are made of steel, depending on the material of the material being manufactured, also called band steel (-鋼) or rough steel (주로), and are mainly treated as building materials. The binding band made of steel is mainly rolled thinly with a rolling mill to have a long strip shape. Steel bands have a thickness of 0.6 to 6 mm and widths of 20 to 1800 mm, and they are used as binding bands when they are molded to have a band shape. They are molded into long pipes to form an electric welded tube or lightweight steel. It also makes a back.

The binding band according to the embodiment of the present invention is mainly used for fixing the interior or finishing material surrounding the outer surface of the building interior and exterior pipes of the cylindrical shape to the column-shaped pipe or structure.

For example, when the pipe is wrapped with a heat insulating material to prevent freezing of the water pipe, by tightening and fixing the binding band at regular intervals of the pipe, the shape of the heat insulating material surrounds the pipe is maintained. Binding bands, especially steel bands, are mainly manufactured from stainless steel or carbon steel.

In general, the binding band is manufactured by coating at least two layers of thin plates. This is due to the structure of the binding portion, which is a portion where both ends of the binding band are reunited after wrapping at least one circumference of an object for binding to bind the band-shaped binding band. With the center band of the binding band as the axis, the binding portion provided at one end of the binding band (hereinafter referred to as the receiving end) is accommodated in the form of enclosing the opposite end (hereinafter referred to as the insertion end), and the object is bound by the binding band. Afterwards, the insertion end is flipped back in the opposite direction to the insertion direction with respect to the binding part to fix the insertion end so as not to be separated from the binding part of the receiving end, and additionally provided with a separate fastening device such as a screw to strengthen the binding force. Is common.

Due to the structure of the binding portion, in the manufacture of the binding band, a post-process required to separately form a screw groove in the center band after forming the binding band. As a result, the process time is increased during the production of the binding band, resulting in a cost loss due to time loss.

In addition, the function of the binding part of the conventional binding band only serves as a guide rail function of the insertion end and the support when the insertion end is folded back, and does not perform other functions. In addition, in the conventional binding band, one end provided with a fastening groove has a flat band structure, so that when tightly binding, there is no handle or groove on the one end, so the operator grasps one end with bare hands and pulls it with force. It has a structure to make it. Binding bands, especially steel bands made of steel, are generally a smooth surface, so it is necessary to wear gloves to prevent slippage. Therefore, the work that the operator pulls by hand is inefficient, takes a long time, and is difficult to tighten firmly.

In addition, the conventional binding band has a narrow structure of the inlet portion of the binding portion and a low height, the operator grasps one end with the binding portion of the binding band and puts one end into the binding portion provided at the opposite end. In order to pull and bind, delicate attention is required, which increases the working time.

In order to solve the above problems, the binding band according to the present invention is provided with a solution for each.

Since the structure for fixing the insertion end so that the insertion end is not separated from the binding end of the receiving end is not strong, it is necessary to provide a separate fastening device such as a screw to strengthen the binding force. There is, but the binding band of the present invention is provided with a binding portion for engaging the fastening groove and the engaging protrusion is fixed to provide a sufficient binding force, there is no need to provide an additional separate fastening device.

In some fastening bands, there is a case where a locking jaw of another structure is used to push the hook, but such a push-binding structure is quite difficult for an operator to work. After the insertion end of the binding band according to an embodiment of the present invention to pass through the binding portion, grasp the insertion end and pull enough, so that the locking protrusion provided inside the binding portion is caught in the fastening groove of the appropriate position, so that the binding is not released. There is a characteristic. The locking projection and the fastening groove are strongly bound so that no additional screw or the like is required.

In addition, in the case of holding and pulling the insertion end, as described above, the insertion end portion, which is the portion of the user directly holding and pulling, has a thin belt shape without a handle. There is a problem falling. Therefore, the binding band according to the embodiment of the present invention is provided with a pull groove in the insertion end so that the user can easily bind the binding band by pulling the insertion end using a tool such as a hook in addition to the bare hand. This increases the work efficiency due to the reduction of working time, thereby reducing the cost.

In addition, the conventional binding band has a narrow structure of the inlet portion of the binding portion is low in shape, the operator grasps the receiving end provided with the binding portion of the binding band, the insertion end is engaged with the receiving end provided at the opposite end In order to pull and fasten the inserted insertion end after insertion, it is necessary to pay attention to the insertion end part through the engagement part of the binding part, which has a disadvantage in that the working time increases, and the binding band according to the embodiment of the present invention is bound. The height of the engaging portion of the part is made high so that the user can easily bind the binding band during work.

Finally, by applying heat and pressure to the engagement portion provided in the binding portion through a stamping process, a portion of the engagement portion has an ohmic width. Thus, the engagement portion of the binding portion simply serves as a guide rail of the movement path with respect to the binding portion of the insertion end, and the recess formed by the stamping improves the binding force.

A more detailed structure of the binding band according to the embodiment of the present invention will be described in the embodiment section with reference to the accompanying drawings.
