[Problems to be Solved by the Invention] However, conventionally, when constructing a refrigerator or a freezer, the construction manager of the building determines the position of the floor (F / L) based on the injured reference point to form a frame. Attach. However, concrete casting companies refer to different reference points, and the concrete casting itself has an error of about ± 20 mm, and the finished floor often does not match the three-sided frame mounting position. If the floor finishes lower than the set position, the door must be mounted via a spacer, and if the floor finishes higher, the door may not be able to be mounted.

[0005] In the door mounting operation, the roller for pressing down the lower end of the sliding door cannot be mounted unless the concrete floor surface below the storage opening is finished. He had to go to the construction site twice later, which was very troublesome.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to install a three-way frame and a sliding door before placing concrete on a floor surface, and also to install a roller for pressing down a lower end of the sliding door. Refrigerator that can be completed completely, including the floor concrete at the floor level when the three-sided frame is installed, and that can be cast very reliably and therefore the construction cost is low. It is an object of the present invention to provide a device for pressing down the lower end of a sliding door.
