PROBLEM TO BE SOLVED: To facilitate entrance of an aged person and a sickly person to and from a service entrance and to effectively utilize a space by a method wherein an openable cover body is arranged at the opening part of a containing chamber body having an upper surface being opened and communicated with an internal space and a side forming a slope. SOLUTION: A containing chamber body 1 made of resin concrete adjoining to a service entrance door 3 and arranged on the outdoor side has an upper surface being opened and an upper surface opening part 11 communicated with an internal space 10 in which an object 4 to be contained is contained, and two sides form slopes 12a and 12b. The gradients of slopes 12a and 12b are set to approximate 1/8-1/12 and a plurality of grooves G for preventing the occurrence of a slide crossing an inclination direction is formed in the slopes 12a and 12b. An openable cover body 2 is arranged at an upper surface opening part 11 of a containing chamber body 1. For example, the cover body 2 made of fiber-reinforced plastic is fitted in a recessed part 11a formed along the upper surface opening part 11 of the containing chamber body 1. Inorganic tiles are laid on the upper surface of the cover body 2 and the upper surface forms a flat step surface continued to slopes 12a and 12b. |
