Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for curing an opening / closing door such as an entrance door, a self-service door, and a gate, and a cured opening / closing door.

[0002]

2. Description of the Related Art A door for opening and closing is a substantially plate-shaped body having a predetermined thickness, width and length. A hinge is attached to one side in the width direction and a lock is attached to the other side in the width direction at an installation site. Prepared for installation by attaching the hinge to the fixed side and openable and closable.

Since the opening / closing door is assembled in a factory or the like and is transported to the installation site, it is cured so as not to be damaged during the transportation.

For example, the opening / closing door is inserted into a bag larger than the opening / closing door made of a shrink film which contracts in the longitudinal and lateral directions, and the whole is heated to move the shrink film in the longitudinal and lateral directions. The entire door for opening and closing is covered with a shrink film by shrinking to close the door for opening and closing.

A tape is attached to the entire surface of the opening / closing door to cover the entire opening / closing door with the tape.

[0006]

In order to attach the opening / closing door at the installation site, the hinge film and the lock are attached to one side portion and the other side portion in the width direction of the opening / closing door as described above. Since the tape becomes an obstacle, the shrink film and the tape are all peeled off before the hinge and lock are attached.

As described above, when the shrink film and the tape are all peeled off from the opening / closing door, the entire surface of the opening / closing door is exposed and may be damaged by interference with the fixed side or the like during mounting.

Also, the building may not be completed at the time when the opening / closing door is attached due to the construction order of the building, etc.
If the door for opening and closing is left with the entire surface exposed, it may be deteriorated or damaged by wind and rain.

For this reason, conventionally, after the hinges and locks are attached, the opening / closing door is re-cured with cardboard to prevent damage at the time of installation, and the door is deteriorated or damaged from installation to completion of the building. This prevents re-curing work after attaching the hinge and the lock.

In order to solve this problem, only the shrink film, the hinge mounting portion and the lock mounting portion of the tape may be peeled off. To do this, the shrink film and tape are cut off with a cutter or the like and peeled off. This is not practical because the peeling work is troublesome and the surface of the opening / closing door may be accidentally damaged.

Therefore, an object of the present invention is to provide a cured door for opening and closing and a method for curing the door for opening and closing, which can solve the above-mentioned problems.
