Description

Metal Band {METAL BAND}

The present invention relates to a metal band that performs the function of a circular fastener, and more particularly, when the surface of a circular structure such as a pipe or a columnar structure surrounding the interior or finishing material, the member tightly fixed to the structure The present invention relates to a metal band in the form of a thin 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. Metal bands are rolled thinly with a rolling mill to have a long strip shape. 0.6 ~ 6mm thick and 20 ~ 1800mm wide, it is used as a metal band when it is molded and has a band shape, and it is formed into a long tube shape to make an electric welded tube or a light-weight steel. .

Metal band according to an 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 pipe 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 a metal band at regular intervals of the pipe, the heat insulating material surrounds the pipe. The metal band can be manufactured as long as the metal has a certain strength, and is mainly made of stainless steel or carbon steel sheet, among steels with high strength.

Generally, metal bands are made of at least two layers of thin steel plates. This is because of the structure of the binding portion, which is a portion where both ends of the metal band are re-metred after wrapping at least one circumference of the object to be bound to bind the band-shaped metal band. With the center band of the metal band as the axis, the binding portion provided at one end of the metal band (hereinafter referred to as the receiving end) is accommodated in the form of surrounding the other end (hereinafter referred to as the insertion end), and the metal band is surrounded by an object for binding. 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, when the metal band is manufactured, a post process is required in which the metal band is separately formed after the metal band is formed. As a result, the process time is increased when the metal band is manufactured, and the cost is lost due to the time loss.

In addition, the function of the binding portion of the conventional metal 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, the conventional metal band has a structure in which one end having a fastening groove has a flat band structure, so that when tightly binding, the operator grasps one end with bare hands and pulls it by force. In such a case, since the metal band is generally smooth, it is cumbersome to wear gloves or the like to prevent slippage. Therefore, the work that the operator pulls by hand is inefficient, takes a long time, and is difficult to tighten firmly.

Furthermore, in the case of the invention described in another patent application No. 10-2008-0116320 of the inventor of the present invention, since it must be folded at least twice along the fold line formed, it takes a long time when an operator performs a large amount of work. It is necessary to supplement this. Therefore, it is necessary to appropriately include the form of the interlocking wing portion of the receiving end and the fold line formed at the receiving end of the binding portion so that the work of the binding portion is completed by only one folding operation.

On the basis of the structure that the metal band is enclosed with the object to be bound, and then the insertion end is folded back in the opposite direction to the insertion direction around the binding part to fix the insertion end so as not to be separated from the binding part of the receiving end. The binding force of the metal band was further improved by further providing engagement blades on both the left and right sides.

In addition, the metal band according to the embodiment of the present invention is integrally formed without having a laminated structure of two or more layers. That is, by providing the insertion end, the receiving end, the interlocking wing and the binding unit integrally, it is possible to manufacture in a single manufacturing process, it is excellent in production efficiency because no post-process such as rivet fastening 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 metal band according to the embodiment of the present invention has a pull groove at the insertion end so that the user can easily bind the metal 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 particular, since the engagement end can be fixed to the receiving end by only one folding operation by simplifying the folding operation of the engaging blade, it is excellent in terms of work efficiency.

As used herein, the term "binding force" is an abstract concept indicating the extent to which the metal band is bound to the binding object, and the high binding force means that the metal band is firmly bound to the binding object.

More detailed structure of the metal band according to an embodiment of the present invention will be described in the embodiment section with reference to the accompanying drawings.

The metal band according to the embodiment of the present invention is provided with a sufficient binding force by engaging the fastening groove and the binding portion, and since the engagement wing provides the auxiliary binding force, it is not necessary to provide an additional separate fastening device, which is efficient in terms of time and cost.

Metal band according to an embodiment of the present invention is provided with a pull groove in the insertion end so that the user can easily bind the metal band by pulling the insertion end using a tool such as a hook in addition to the bare hand.
