Door structure for preventing habitants from being confined indoors and door remodeling member for the door structure

Abstract

A door structure capable of preventing inhabitants from being confined in a room in a large earthquake. In the door structure, an upper wall (3) tilting upward in a door opening direction (X) relative to a horizontal direction is formed at the upper end of a door body (1), and a tilted surface (12) is also formed on a door upper frame (11) correspondingly to the upper wall. Also, rotating memberssuch as rollers in contact with a door lower frame are installed at the lower wall of the door body (1). Accordingly, when a door frame (10) is deformed by the earthquake, a force in the door openingdirection (X) acts on the door body (1) since the door frame (10) presses the upper wall (3) of the door body (1). The rotating members at the lower wall facilitates the door opening operation.

Description

technical field [0001] The invention relates to a door structure used to prevent being locked indoors when a major earthquake occurs, in particular to a door structure body and a door transformation component suitable for buildings such as community houses. Background technique [0002] In general, steel doors are widely used for gates of buildings including high-rise houses and the like. When such a steel door is used, the earthquake deforms and destroys the walls around the door, so that not only the door frame and the hinge for opening and closing the door, but also the door itself is deformed, making it impossible to open and close the door. Things can happen that keep residents indoors and make rescue difficult. [0003] Therefore, in order to solve the above-mentioned problems, a technology that can easily open and close the door even if the walls of the building are deformed due to an earthquake (refer to Japanese Patent Laid-Open No. 8-333963 and Japanese Patent Lai...

AI Technical Summary

Problems solved by technology

Therefore, there is a problem that the flat surface of the door frame clamps the flat surface of the door vertically or horizontally depending on the damage state of the wall and the deformation state of the hinge during a major earthquake, and the door may not be opened.

[0005] In addition, the tapered surface and flat surface on the door and door frame can be easily applied to a new building, but if it is applied to an existing building, it is necessary to carry out the modification or replacement of the door, the construction of the door frame, etc. , It requires a lot of cost and time-consuming engineering, so it is actually difficult to apply to existing buildings
