BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding band which is used by being wound around an object to be handled, and more particularly, it is used as a protective band for preventing breakage of a tubular body such as a fume tube during handling and transportation. The present invention relates to a binding band suitable for

[0002]

2. Description of the Related Art As a binding band to be wound around an object to be handled, for example, a relatively small band for bundling and organizing wiring cords of household electric appliances, OA equipment, industrial equipment, etc. is well known. ing. However, there is no binding band that can be applied to the tightening of large articles such as the handling of tubular bodies such as fume tubes.

By the way, in waterworks and sewerage works, concrete fume pipes are used as pipes which are buried in the soil or in water to circulate fluids such as water and sewage. In particular, the fume pipe, which is the main pipe for water and sewage equipment, is usually 15
Those having a large diameter of about 0 to 600 are used. The fume tube has a fixed length of a fixed length, spigot part related to the joint part,
It is connected via a socket to meet the demand for long pipelines.

The socket portion, which is one of the tube ends of the fume tube, is formed with a socket having a diameter slightly larger than the outside diameter of the tube, and the other end of the pipette, the spigot portion, has an outside diameter of the tube. With a circumferential groove of a specified width, when fitted with a mating socket, a sealing member is interposed in this circumferential groove to prevent fluid leakage from the connection part or foreign substance intrusion from the outside. It is configured. Therefore, a thin portion is present in the spigot portion and the socket portion as compared with the wall thickness of the pipe body.

[0005]

Such a fume pipe is used by transporting a fixed length object from a manufacturing plant or a stockyard to a construction site and connecting it on site. During storage and transportation in the stockyard, standard-sized fume tubes are randomly stacked and handled by ropes or transported by vehicle. At this time, the contact between the fume tubes and the impact of vibration or the like may damage the slightly thin portions of the spigot portion and the socket portion or the portion whose shape is changed as compared with the pipe body.

[0006] Therefore, conventionally, the area around the fragile spigot portion and the socket portion is tied in advance with a rope to form a cushion for preventing contact and collision of the fume tubes. However, recently, as the rope itself has run short,
This tendency is becoming more prominent as more field workers become less proficient in tying rope, especially as the number of foreign laborers increases. This has led to demands for protective bands that can be easily handled by unskilled persons.

The present invention was made in order to solve the above-mentioned problems of the prior art, and an object of the present invention (first object)
Is to provide a binding band that functions as a protective band that alleviates impacts when stacking fume tubes and the like interfere with each other during handling and transportation of the fume tubes and prevents damage.

Another object (second object) of the present invention is to provide a binding band which is easy to handle for handling large and small items such as a fume tube, is easy to handle, and has a high reliability as a protective band. is there.

[0009]

In order to achieve the above first object, the most basic structure of the binding band according to the present invention comprises a band-shaped winding fastening portion, and one surface in contact with an object to be handled is smooth. The surface is the surface and the surface opposite to the smooth surface is the uneven surface.

Further, in order to achieve the above first object,
A more specific configuration of the binding band according to the present invention is, in a binding band used by being wound around an object to be handled, one surface of the band-shaped winding portion is a smooth surface and the surface opposite to the smooth surface is an uneven surface. Along with the joint locking portion, the other end of the band or the other end of the band is fastened to the end portion of the band-shaped winding tightening portion having a predetermined length, and the joint formed on the other end of the band. It has a smooth portion to be superposed on the locking portion. Here, the band is made of a thermoplastic resin and is formed into a flexible band shape.

Further, in order to achieve the above second object, the binding band according to the present invention has, in addition to the above structure,
The joint locking portion is provided with guide flanges on both sides of the band-shaped band for guiding and inserting both side surfaces of the mating band. Further, the uneven surface of the winding tightening portion is formed with a large number of protrusions in a range that escapes the width of the guide flange of the joint locking portion from both sides of the band width.

More specifically, rough surfaces that engage with each other are formed on the surfaces of the joining and engaging portion that abut against the mating band and the surfaces of the smooth portion that should be overlapped with the joining and engaging portion that abut each other. It is a thing. In addition, a strip-shaped part is extended to the outside in the longitudinal direction from the guide flange of the joint locking part to form a thin smooth surface with an inclination that allows close contact with the object to be handled, The device is equipped with a knob for work during handling. Furthermore, a work opening for handling the band is provided at the end of the band on the side opposite to the joint locking part.

[0013]

The function of each of the above technical means is as follows.
Since the binding band of the present invention has a smooth surface on one side and an uneven surface on the other side, for example, when stacking and transporting fume tubes, by winding the binding band around each fume tube, the band is smoothed. The surface is in close contact with the fume tube, and the large number of projections and depressions on the uneven surface serve as a buffer function for alleviating shocks such as contact and vibration between the fume tubes. Therefore, it is possible to prevent the fume pipe and the like from being damaged during handling and transportation.

The binding band is provided on both sides of the band-shaped band.
Since a guide flange that guides and inserts both sides of the mating band is provided and the other end of the band or one end of the other band is overlapped and fastened, a plurality of binding bands of a predetermined length are connected. By doing so, it is easy to handle large and small items such as fume tubes, and the handling is simple.

The contact surface of the joint locking portion with the mating band and the contact surface of the smooth portion to be overlapped with each other,
Since the rough surfaces that engage with each other are formed, it is possible to improve the reliability of the joining when they are overlapped and tightened and fixed.

Further, since the strip-shaped portion is extended to the outer side in the longitudinal direction from the guide flange of the joint locking portion to form a thin smooth surface having an inclination so that it can be brought into close contact with an object to be handled, a band closely adhering to an object to be handled such as a fume tube is formed. The surface is smooth with no stepped parts, and is easy to handle.

Further, since a work knob for handling the band is provided on the outer side of the guide flange of the joint locking portion, the work for joining the band or releasing the joint can be performed easily. In addition, since an opening for working when handling the band is provided at the end of the band on the side of the anti-joint locking portion, it is easy to work by inserting pliers nails from this opening, especially when releasing the joint. .
