Description

  The present invention relates to a renovation structure and a refurbishment method for a building opening in which a door such as a swing type door in the opening of the building is refurbished to a sliding automatic door.

  In stores where swing-type hinged doors have been used for openings, the doors are pushed or pulled when the force is weak, such as children, elderly people, or people with disabilities, or people with luggage. It was not easy to open and close. Therefore, in stores and the like, work is being carried out to renovate the swing type swing door to a slide type (sliding door type) automatic door so that people can easily enter and exit.

For example, in the cross-sectional view of the opening 1 shown in FIG. 11, in an existing store, a swing type hinged door 2 is attached to the opening 1, and a FIX window is formed on the adjacent wall surface via the vertical frame 15 of the opening 1. The FIX window 4 extends from the floor surface to the ceiling, for example, and is attached to the entire surface.
In such an existing store, when the opening 1 is refurbished from the hinged door 2 to a sliding automatic door, as shown in the longitudinal sectional view of FIG. 12, the FIX window 4 adjacent to the opening 1 where the opening / closing door is installed. Becomes the sleeve. Then, on the sleeve part from which the glass panel of the FIX window 4 has been removed, an invisible 8 for attaching a box including a rail 6 and an engine 7 for operating the opening / closing door of the automatic door is installed. It was necessary to install new glass panels 9a and 9b.

  Moreover, in patent document 1, when installing the glass panel extended to the whole surface from a floor to a ceiling, in order to prevent that a person and an instrument collide, a bracket is attached to the area | region which removed the glass groove of the glass panel in a right and left vertical frame.
