Abstract

<P>PROBLEM TO BE SOLVED: To solve the following problem: a conventional aseismatic reinforcing device cannot be installed unless part of a building is removed and restored to the original position, a foundation and the like have to be reinforced because stresses are concentrated on the sill and foundation of a bearing wall reinforced: and to provide aseismatic reinforcement not requiring removal and restoration work to an opening such as a window. <P>SOLUTION: Movable or removably-attached low rigidity aseismatic reinforcing devices 2, 3, 4, 5 are designed to be installed in openings 6, 7, 8, 9 such as windows. Walls located above/below the opening abut on structural materials α, β, γ of a building body. By installing the low rigidity aseismatic reinforcing device equivalent to the wall 1 in the opening and the like, rigidity equivalent to that of the bearing wall can be demonstrated even if the rigidity is low. Although the individual devices have low rigidity, a building high in rigidity as a whole can be obtained. <P>COPYRIGHT: (C)2010,JPO&INPIT

New buildings do not have the concept of seismic reinforcement, and the prior art was devised for the purpose of retrofitting existing buildings. Nevertheless, when installing the seismic device, a part of the existing building such as a wall or window must be removed and restored, and it cannot be installed, causing the seismic repair work to be expensive. Therefore, the number of reinforcements is limited to a small number, and the rigidity of the seismic device is increased accordingly to reduce the price. However, the highly rigid reinforcement device is expensive. Therefore, there is a strong need for a reinforcing method that can be applied without much modification to existing buildings.

In addition, in the prior art, when the rigidity of the reinforced wall is improved, stress concentrates on the foundation and foundation of the reinforced bearing wall, which becomes the pulling force of the pillar and tries to lift the pillar from the foundation. Power comes to work. Therefore, it is necessary to take measures to suppress the lifting force. This is because the purpose is to reduce the construction cost by limiting the reinforcement points of existing walls and windows to the minimum. Reinforcement can be achieved without generating the pull-out force of the pillars by increasing the number of portions to be reinforced by reducing the rigidity of the reinforcing wall. However, the number of walls in a single house is limited, and the number of walls tends to decrease due to renovation work, etc., so it is necessary to provide seismic reinforcement for openings such as windows.

An anti-seismic reinforcement device characterized by the fact that movable braces are arranged diagonally and with low rigidity in the openings of windows and other windows found on the outer walls of wooden houses, with almost no removal or restoration work for existing buildings. The low rigidity referred to here indicates, for example, a region in which the wall amount magnification defined by the Building Standards Act is about 0.5 to 2.0 per 90 cm wall length.

The bracing is telescopic, and one point is fixed to the top of the pillar of the existing building with a hinge, and the other point is also hinged to the bottom of the pillar on the opposite side of the existing building. A sliding hinge is provided and operated to fix it diagonally. When the function as an opening is satisfied, the contact hinge is slid to fix the brace to the top of the opening and the column. Seismic reinforcement device.
The slide-type hinge here refers to a hinge in which a rail is provided on one of the two braces and the end of the other brace is slid on the rail.
(C)
The brace is a slide type, and when the two braces with hinges in the center are crossed and fixed by applying pressure to the four corners of the opening to satisfy the function as the opening, Seismic reinforcement device, characterized in that it can be removed and removed as a seismic device.
(D)
The brace is a detachable brace, which is made up of two rope braces, fixed at the top two locations of the opening, and provided with connecting devices at the two bottom ends of the aperture, and the rope is fixed diagonally. When the function as the opening is satisfied, the seismic reinforcement device is characterized in that the rope is removed from the coupling device and attached to both sides of the column.
As used herein, rope-style bracing refers to foldable bracing made of fiber or wire.
