PROBLEM TO BE SOLVED: To provide a wall-like structure that lowers the temperature by vaporization heat and has high visual appreciation.SOLUTION: A wall-like structure 1 is composed of a support member 6f that supports three or more stepped portions 2 to 4 and the three or more stepped portions 2 to 4 each having a horizontally arranged water-permeable plate-like member with a space provided in the vertical direction, and has water supply means 2a for supplying water to the uppermost stepped portion 2 out of the three or more stepped portions 2 to 4. When water is supplied by the water supply means 2a, water spreads to the uppermost stepped portion 2 due to the water permeability of the plate-like member, water falls from the uppermost stepped portion 2 to the lower stepped portions 3, 4, and water spreads to the stepped portions, further, the water falls from the stepped portions to the lower stepped portions and spreads to the stepped portions, and the water spreading in each stepped portion evaporates, and the temperature can be lowered by the heat of its vaporization. In addition, it is also possible to obtain auditory appreciation by sound when water collides with the stepped portions 3 and 4 as it falls.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】気化熱により気温を下げる壁状構造物であって、視覚的な鑑賞性の高いものを提供すること。【解決手段】壁状構造物1は、水平に配した透水性を有する板状部材をそれぞれ有する3以上の段部2~4及び3以上の段部2~4を鉛直方向に空間を設けて支持する支持部材6fを備え、3以上の段部2~4のうちの最上段の段部2に給水する給水手段2aを有する。給水手段2aにより給水すると、板状部材の透水性により最上段の段部2に水が広がり、最上段の段部2から下の段部3,4に水が落ちてその段部に水が広がり、さらにその段部から下の段部に水が落ちてその段部に広がり、各段部に広がった水が気化することでその気化熱により気温を下げることができる。また、水が落下して段部3,4に衝突する際の音による聴覚的な鑑賞性を得ることもできる。【選択図】図1
