Description

  The present invention relates to a seismic reinforcement structure.

  For example, in the case of buildings, which are often found in apartment buildings, etc., the seismic reinforcement of buildings with long girder directions perpendicular to the length between the beams in the structure is ensured by the partition walls, which are earthquake-resistant walls. The method of reinforcing from the outer shell in the girder direction is widely adopted. At that time, there is a demand for a reinforcing method that secures an opening area necessary for a house and that does not easily cause problems such as twisting during an earthquake.

For this reason, the reinforcement method which can ensure a required opening area and can reduce a reinforcement member by mutually connecting adjacent existing structures is proposed (patent document 1).
That is, according to Patent Document 1, two or more adjacent existing structures are arranged separated from each other. At this time, the extended line in the carry direction of one structure is arranged at a position intersecting the outer wall in the carry direction of the other structure. In this configuration, existing structures that cross each other are connected by a connecting member provided in the extension line direction.
This makes it possible to supplement the seismic performance of the structural surface with low proof stress and rigidity of one existing structure with the surface with high proof strength and rigidity of the other existing structure. As a result, the earthquake resistance of a plurality of existing structures can be improved without adding an extra seismic reinforcing frame to the existing structures. At this time, a necessary opening area is also ensured.

However, Patent Document 1 cannot be applied to a structure in which an extension line in the traveling direction of one structure does not intersect with an outer wall in the traveling direction of the other structure.

That is, by integrating a plurality of plate-like houses with the outer frame, it is possible to suppress the occurrence of problems such as torsion during an earthquake.
In addition, the reinforcing member is not disposed on the outer wall on the side opposite to the side on which the outer frame is constructed, so that the opening area in the plate-like house is secured and the feeling of pressure is eliminated.
That is, it is possible to seismically reinforce a plate-like house in which the extension line in the carry direction of one plate-like house does not intersect the outer wall of the other plate-like house in the carry direction.

  The invention according to claim 2 is the seismic reinforcement structure according to claim 1, wherein the outer frame is a frame constructed of column beams and arranged to face the plate-like house, and a horizontal frame that connects the frames to each other. It is characterized by having.

According to the second aspect of the present invention, the frame constructed of column beams is arranged facing the plate-like house and connected by the connecting member. The frames are connected by a horizontal frame.
