JP3051072U - Replacement seismic door - Google Patents

Abstract

(57) [Summary] [Purpose] This invention aims to replace old iron entrance doors with new iron or stainless steel doors, make them as small as possible, and provide them with earthquake resistance. The door has been changed so that it can be opened and closed safely and in an emergency. [Construction] The frame of the door part of the newly installed door is installed in a shape that protrudes out of the existing frame, so that the entrance and exit dimensions are not reduced as much as possible, and the gap between the frame and the door is made, and the interlayer displacement 120 according to the Building Standard Law Construction Order The shape was such that it could withstand a one-third deformation.

Description

[Detailed description of the invention] In this invention, the old steel entrance door is removed without breaking it, and only the existing iron frame is left without breaking, and a new door of seismic specification is installed.

Replacement of old entrance doors of public housing, etc. is difficult because of the construction period and other reasons, and it is difficult to replace the doors. For this reason, only the doors are removed, leaving the existing iron frame, and new doors are installed inside. However, for the purpose of the entrance, a new door is installed at the same position as the existing iron frame so that the opening size of the current door does not become as small as possible. Therefore, there is no gap and the door cannot be opened because it cannot withstand the deformation with the interlayer displacement of 1/120 during the earthquake.

 Therefore, in the present invention, the existing iron frame is left as before, the door is removed and a new iron or stainless steel door is installed, but the part of the newly installed door frame where the door enters is outside the existing iron frame. Create a gap between the frame and the door so that it can withstand a deformation of 1/120 of the interstory displacement according to the Building Standards Law enforcement order. I tried to prevent it from opening.

 With this idea, it is no longer said that the entrance door of the old estate will not open in the event of an earthquake, so that it can be used safely and reliably as an evacuation doorway.

Claims (1)

[Utility model registration claims] 1. A new iron or stainless steel door is attached inside the remaining existing iron frame while leaving only the door while leaving the existing door iron frame. In this case, in order to keep the opening size of the door as small as possible, the frame part where the door of the newly installed door enters should be made to protrude to the outside of the existing steel frame, and the deformation of the interlayer displacement by 1/120 according to the Building Standard Law Construction Order. The door is designed to withstand the earthquake, preventing the door from opening during an earthquake.
