Abstract: A space structure is composed of a post member and a horizontal beam member. The post member has a post member groove portion that constitutes a semi-closed space having an opening portion in a cross section of the post member and extends along its axial direction. The horizontal beam member has one or plurality of horizontal beam member groove portions each of which constitutes a semi-closed space having an opening portion in a cross section of the horizontal beam member and extends along its axial direction.

Abstract: In a storage unit (60) of a rectangular parallel-piped shape which is formed of a pair of horizontal panels (61) and a pair of vertical panels (62) that are connected with one another in an annular fashion, each of said horizontal panels (61) has a fitting groove (70) extending in a lateral direction thereof into which a part of a structural member of a structural body into which the storage unit is built, and each of horizontal panels also has a positioning groove (71) extending in a lateral direction thereof into which a protrusion formed on a horizontal cover covering the one horizontal panel is fitted. As a result, it becomes possible to properly construct a storage space in accordance with the purpose of use of a user.

Abstract: An object is to provide a space providing system that can be flexibly adapted to a modification to the configuration of a space structure in accordance with the intended purpose of a conference or exhibition and to replacement or addition of an information apparatus. In a space structure constructed by joining one or more post members extending upwardly from the floor and one or more horizontal beams extending parallel to the floor, connection means that can be fixed at a desired position is provided, by which a service providing apparatus is connected to the space structure. In addition, a space management server that detects and manages a service provided by the service providing apparatus is provided.

Abstract: A desk system comprises leg panels of a desired thickness, top board support members each having a top support surface and capable of being fastened to the leg panel such that the top support surface extends above the leg panel, top boards respectively having desired shapes and capable of being fastened to the top support surfaces of the top board support members, and longitudinal beams connecting the adjacent leg panels and forming a trough. Each of the leg panels is a hollow structure having a cut upper corner, an end part of each longitudinal beam is fastened to the cut upper corner. The desk system is capable of being assembled in a desired form.
