Title:
DOOR FRAME STRUCTURE AND METHOD FOR MOUNTING DOOR FRAME STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2016/139864
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a door frame structure that has increased rigidity, is prevented from being deformed by a relative story displacement of a building caused when an earthquake occurs, and is easy to mount, as well as a method for mounting the door frame structure. [Solution] A door frame structure 1 includes an inner frame body 2 and an outer frame body 3. First reinforcing members 9 are slidably disposed in first grooves 7 provided in the outer periphery of the inner frame body 2. Furthermore, second reinforcing members 10 are disposed in second grooves 8 provided in the outer periphery of the outer frame body 3. The door frame structure 1 is indirectly mounted to a wall 4 via mounting angles 11, which are fixed to the first reinforcing members 9. Accordingly, the door frame structure 1 does not follow the relative story displacement of the wall 4 caused by lateral vibrations during an earthquake, and hence, deformation of the door frame structure 1 is minimized, allowing a door 31 to be opened and closed even in an emergency.
