Description

  The present invention relates to a seismic reinforcement structure in a building such as a house.

In recent years, the demand for seismic reinforcement work for existing buildings such as houses has increased.
As an example of seismic reinforcement work, there is a proposal to fix braces, shafts, etc. on the outer wall.
As a means for improving the earthquake resistance function, it is preferable to arrange the bearing walls in a balanced manner in a plane.
However, as shown in FIG. 13 (a), the building 100 which is a Japanese house generally has a lighting opening 101 on the south side, and as a result, the south side 102, the north side 103, There was a problem in that the amount of walls in the wall was unbalanced and the seismic function decreased.

In order to solve this problem, in Patent Document 1, as shown in FIG. 13B, the outer wall surface of the opening 101 in which the window frame or the like is disposed in the building 100 which is a general house such as a wooden house, or the opening. An opening seismic reinforcement frame 104 in a general house is disclosed that is fixed to the inner peripheral side of the house and imparts earthquake resistance to the entire house.
However, there is a problem that the scenery seen from the opening 101 is damaged, and the beauty of the building 100 itself is also damaged.
Japanese Patent Laid-Open No. 2002-371852

  In view of the above problems, the present invention provides a seismic reinforcement structure around an opening that can effectively reinforce an opening around an opening that is difficult to reinforce due to a weak seismic strength of an outer wall in an existing building such as a house, with a better aesthetic appearance. The purpose is to provide.

The seismic reinforcement structure around the opening according to the present invention includes a vertical reinforcing column disposed in parallel along the left and right sides of the opening vertical frame member and a horizontal reinforcement column disposed in parallel along the upper and lower sides of the opening frame member. The reinforcing lintel and the reinforcing window base, which are reinforcing materials, form a rectangular reinforcing frame around the opening, and the horizontal reinforcing material is fixed to the vertical reinforcing column by pin joints in terms of structural mechanics. A damping damper is provided in at least one of the upper and lower pin joints.

The damping damper may be provided on both the upper and lower sides of the lateral reinforcing material.

The upper end of the vertical reinforcing column is preferably fixed to an eaves girder and / or torso which is a horizontal member in the main structure of the building.

The lower end portion of the vertical reinforcing column is preferably fixed to a base which is a horizontal member provided on the foundation in the main structure of the building, and the lower end portion of the vertical reinforcing column may be extended to the base and fixed to the foundation.

The vibration damper is preferably provided with an elastic body between damper plates facing each other provided in the vicinity of the joint between the vertical reinforcing column and the horizontal reinforcing member.

The entire outer portion of the rectangular reinforcing frame may be covered with a cover around the opening, and the upper horizontal reinforcing material cover included in the cover around the opening may be a hook.

The vertical reinforcement pillar is fixed to the eaves girder and / or torso, which is the horizontal material in the main structure of the building, via the joint member that penetrates the outer wall finishing material, and the reinforcing frame is fixed to the outer wall finishing material of the existing building It is good to do.

In the seismic reinforcement structure around the opening according to the present invention, the seismic strength of the outer wall in an existing building such as a house is weak, and the view around the opening that is difficult to reinforce is effectively damaged from the inside of the building through the opening. Without covering the opening with a cover, the seismic function equivalent to that of placing a load-bearing wall in a well-balanced plane in an existing building can be realized without impairing the beauty of the area around the opening. In addition to the vertical reinforcing column and the horizontal reinforcing member, the damper plate is provided with an elastic body that reduces and absorbs vibration caused by earthquakes, etc., between the mutually opposing damper plates. An effect can be obtained.
