PROBLEM TO BE SOLVED: To provide an underground space structure in which an underground space can be formed by accurately positioning liner plates, which become the remaining outer mold frame, without requiring skill when constructing the underground space in a small-scale building.SOLUTION: An underground space structure includes: a plurality of lower end part pressing fittings 16 fixed to concrete sub-slab 24 and attached along an outer peripheral line of a planned attachment position of a remaining outer mold frame 11, on the bottom part of an excavated hole 23 formed by digging foundation ground 21 below a building 20; a plurality of base channel members 14, 15 installed continuously and annularly in a peripheral direction while allowing the lower end part pressing fittings 16 to support the outer peripheral surfaces thereof; a base plate part 18 formed inside the base channel members 14, 15 by placing concrete therein; a plurality of liner plates 12, 13 installed above the base channel members 14, 15 in an overlapping manner; a peripheral wall part 17 formed by placing the concrete inside the remaining outer mold frame 11, which is formed by the liner plates 12, 13 and the base channel members 14, 15. |
