Description

  The present invention relates to a structure.

  A seismic reinforcement method for installing a brace or a seismic wall on a structure frame is known (see, for example, Patent Document 1).

JP 2006-283455 A

  However, when a brace or a seismic wall is installed on the frame as in the technique disclosed in Patent Document 1, the seismic performance is improved, but the opening of the frame is blocked by the brace or the seismic wall. Therefore, if a brace or a seismic wall is installed on the frame on the outer periphery of the structure, the openability may be reduced.

  In view of the above facts, an object of the present invention is to ensure both seismic resistance and openness at the outer periphery of a structure.

  The structure according to claim 1 is formed in a ground structure composed of a plurality of layers, a box shape having both ends opened, and has a height equivalent to at least one layer of the ground structure. And an earthquake-resistant box-shaped portion disposed on the outer peripheral portion with the opening on one end side facing outward.

  According to the structure which concerns on Claim 1, an earthquake-resistant box-shaped part is formed in the box shape by which both ends were opened. The seismic performance of the ground structure is improved by installing the seismic box-shaped part on the outer periphery of the ground structure.

  The earthquake-resistant box-shaped portion has a height of at least one layer of the ground structure, and is arranged with the opening on one end side facing the outside of the ground structure. Due to the opening on the one end side of the seismic box-shaped portion, a large opening covering substantially one layer of the ground structure is formed in the outer peripheral portion of the ground structure. Therefore, the openness of the outer periphery of the ground structure is ensured.

  As described above, in the present invention, by arranging the earthquake-resistant box-shaped portion on the outer peripheral portion of the ground structure, it is possible to achieve both seismic resistance and openness in the outer peripheral portion of the structure.

  The structure according to claim 2 is the structure according to claim 1, wherein the one end side of the earthquake-resistant box-shaped portion jumps outward from the outer wall of the ground structure.

  According to the structure which concerns on Claim 2, the one end side of an earthquake-resistant box-shaped part jumps outward from the outer wall of a ground structure. Thereby, designability can be improved, ensuring the openness of the outer peripheral part of a ground structure.

  Moreover, the external space of a ground structure can be used efficiently by making the one end side of the earthquake-resistant box-shaped part jumping out from the outer wall of a ground structure into a balcony, a veranda, or a terrace.

  The structure according to claim 3 is the structure according to claim 1 or 2, wherein the seismic box-shaped portion has a height corresponding to a plurality of layers of the ground structure. A blow-through is formed in the outer peripheral portion.

  According to the structure which concerns on Claim 3, an earthquake-resistant box-shaped part has the height for several layers of a ground structure. By disposing the seismic box-shaped portion on the outer peripheral portion of the ground structure, a large opening extending over a plurality of layers is formed on the outer peripheral portion of the ground structure. Therefore, the openness of the ground structure is improved.

  Moreover, the designability is improved by forming a blow-through visible from the outside in the outer peripheral portion of the ground structure by the earthquake-resistant box-shaped portion.

  As described above, according to the structure according to the present invention, it is possible to ensure both seismic resistance and openness at the outer periphery of the structure.
