Abstract

PROBLEM TO BE SOLVED: To provide a seismically strengthened frame door which is for use in an ordinary house such as a wooden house, in place of a rain shutter door, to thereby impart tenacious earthquake resisting properties to the entire house. SOLUTION: The seismically strengthened frame door is obtained by rigidly connecting steel products 1a to 1d such as square pipes or L-shaped ones, to obtain a square frame 2 having a predetermined width and a predetermined height, rigidly coupling reinforcing crosspieces 5 to inner side surfaces of the steel products 1a to 1d of the square frame 2, in one piece, in a manner forming longitudinally and/or laterally symmetrical shape, and forming a number of through portions 6 which are defined by the steel products 1a to 1d and the reinforcing crosspieces 5. In this manner the seismically strengthened frame door A having a kinetic structure equal to a structural wall is obtained. Then, the seismically strengthened frame door A is fitted into a space between a sill 8 and a head jamb 9.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general house such as a wooden house, in which a frame door for seismic strengthening is installed between a threshold and a gate in place of a rain door. The present invention relates to a seismic reinforced frame door for a general house in which a seismic resistance is given to an opening in which a conventional rain door is installed so as to be able to be stored in a door bag so as to enhance the seismic resistance of the entire house. 2. Description of the Related Art Conventionally, in general houses such as wooden houses, shutters are provided, but none of the shutters is provided with seismic reinforcement means. [0003] Therefore, despite the fact that the opening formed by the threshold and the ditch in which the shutter is installed is large, the shutter is not provided with any seismic reinforcement means. There was a problem that it was inferior in earthquake resistance. When the shutter is closed, the shutter frame is considered to have some earthquake resistance even though it is weak. However, if the shutter is stored in a door pocket, the earthquake resistance is further increased. There was a problem of becoming weak. The present invention has been made in order to solve the above-mentioned problems. Instead of a conventional shutter, a sill and a dumbbell forming an opening are provided with a reinforcing bar having a mechanical structure equivalent to that of a structural wall. By keeping the frame door closed all day, including during the day, the seismic resistance of the opening with a threshold and a doorway in ordinary houses such as wooden houses is improved to be equal to or greater than that of the wall. It is an object of the present invention to provide a seismic reinforcement frame door for a general house in which strong seismic resistance is given to the entire house. According to the present invention, a steel material is joined and fixed in a rectangular frame shape to form a rectangular frame having a predetermined width and height, and the inner periphery of the steel material constituting the rectangular frame is formed. Reinforcement bars formed on the side surface in a vertically and / or left and right symmetric shape, or reinforcement bars formed in a vertical and / or left / right asymmetric shape, or reinforcement bars formed in a vertical and / or left / right asymmetric grid shape To form a reinforcing frame door having a mechanical structure equivalent to that of the structural wall by providing a large number of transparent portions formed by the steel materials and the reinforcing bars, and forming the reinforcing frame door as a sill.
