Description

[Technical Field]

[0001] The present invention relates to buildings. [Background technology]

[0002] A well-known example of a building that can achieve a large, column-free space is a building with a tension structure that suspends beam members. The beam members are suspended by wire members that extend diagonally downward away from the building, with their ends fixed to the ground. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2025-008274 A Summary of the Invention [Problem to be solved by the invention]

[0004] In this type of structure, the wire members extend and are fixed in a location far from the building, which requires a large area around the building, making it difficult to adopt in areas with many buildings.

[0005] In addition, the ground to which the wire members are fixed must be strong enough to withstand the tension of the wire members, which makes installation time-consuming. The present invention has been made to solve the above-mentioned problems, and aims to provide a building that makes it easier to expand the area where construction is possible.

[0006] In order to achieve the above object, the present invention provides the following means. A building according to one aspect of the present invention is a building having a tension structure for lifting beam members, characterized in that it comprises a foundation, a plurality of support sections extending upward from the foundation and arranged opposite each other across an internal space, a beam section arranged above the internal space connecting the plurality of support sections, an inclined section extending diagonally upward from the support section toward the opposite side of the beam section, and a wire section extending from the beam member toward the inclined section and extending downward from the inclined section and fixed to the foundation.

[0007] According to the building according to the first aspect of the present invention, the direction in which the wire is pulled can be changed, which means that the building can more easily expand the areas where construction is possible.

[0008] In the first aspect of the above invention, it is preferable that the first aspect is further characterized by the provision of a support portion that is arranged at the end of the support portion, protrudes above the support portion, and supports the wire portion extending from the beam portion toward the inclined portion.

[0009] In this way, by providing the support portion, the pulling direction of the wire can be changed. In other words, the support portion can make it easier to expand the area where construction is possible. [Effects of the Invention]

[0010] The building of the present invention makes it easy to expand the range of expression and to provide a building that is less subject to restrictions on usage hours. [Brief explanation of the drawings]
