Description

[Detailed Description of the Invention] The present invention relates to a packaging covering material for protecting steel pipes such as water pipes, gas pipes, and metal roll-shaped objects from physical impact and preventing them from being scratched.

Traditionally, underground steel pipes such as water pipes and gas pipes have been susceptible to damage due to physical impact during transport before installation, and when damaged pipes are buried underground, the damaged areas may rust over time. , the pipe corrodes and eventually breaks, rendering it useless for its intended purpose.

For this reason, the following measures are taken to effectively protect the circumferential surface of the product during transportation or storage before use, and to protect it from physical external impact.

For example, in the case of water pipes, paper is wrapped around the circumference of a steel pipe, such as a water pipe, whose circumferential surface has been coated with a coating layer of abrasive material such as asphalt in order to prevent rust and corrosion. On top of that, long narrow boards are placed in rows at appropriate intervals,
It was tied up with rope or wire.

However, according to the above-mentioned method, a large number of hands are required especially when arranging and fixing the long and narrow plates in rows on the circumferential surface of the steel pipe, resulting in extremely poor workability.

This proposal was devised in view of the above points, and its configuration will be explained below.

FIG. 1 is a partially enlarged cross-sectional view of the present covering material, and reference numeral 1 is the covering material body, which consists of a flexible sheet 2 with narrow long boards 3 placed at appropriate intervals on one side and glued together. They are lined up and adhered via adhesive 4, and the other side is coated with asphalt 7.

Here, the flexible sheet 2 may be selected from paper, nonwoven fabric, synthetic resin film or sheet, foamable synthetic resin sheet, etc. as appropriate.

Further, as the narrow long board material, plywood board, various synthetic resin boards, etc. are appropriately selected and used.

In particular, considering that the cylindrical columnar body to be covered is a steel pipe such as a water pipe buried in the ground, it is preferable to use a combination of paper as the flexible sheet and plywood as the long narrow board. .

Fig. 2 is a perspective view showing the coating material of the present invention wrapped around a steel pipe, etc., where reference numeral 5 indicates a steel pipe, and the coating material of Fig. 1 is applied to the circumference of the pipe with the asphalt surface side in contact with the steel pipe surface. The main body of the covering material, which is wrapped around the circumferential surface of the steel pipe, is tightened with a stopper band 6 to prevent it from coming off.

Although not shown, if a release paper is temporarily attached to the asphalt side of the coating material of the present invention shown in FIG. 1, it will be extremely convenient to handle it during the summer.

Next, the workability of installing the coating material of the present invention on water supply steel pipes will be compared with the conventional installation work, and the results will be shown in a table.

Comparing the proposed product in the table above with the conventional one, the proposed product requires significantly fewer workers and fewer steps, and the improvement in workability is obvious.

The present covering material constructed as described above has the following effects.

(1) Since the proposed covering material has thin long plates arranged and adhered on the surface of the flexible sheet at appropriate intervals, it is easy to wrap around the circumference of a cylindrical columnar body such as a steel pipe. Wrapping can be done by simply pinching one end of the flexible sheet and wrapping it around the cylindrical columnar body, so the work efficiency is very high and the work can be done by a very small number of people, resulting in labor savings.

(2) In addition, the removal of the proposed covering material from the cylindrical columnar body can be done in one touch by removing the stopper band and simply rewinding the covering material, and the removed covering material can be reused any number of times, making it economical. It is true.

(3) Furthermore, there is no need to recoat the surface of steel pipes such as water pipes with asphalt, and asphalt coating work can be omitted, further improving work efficiency.

In particular, by temporarily adhering release paper to the asphalt-coated surface of the flexible sheet, the product can be easily handled before use, which is extremely convenient.
