PURPOSE:To simplify the process of construction by making floor members from expandable synthetic resin material having either thermoplasticity or plasticity, or both. CONSTITUTION:Floor members 15 to be laid on a floor structure 11 are made of expandable synthetic resin material having thermoplasticity or plasticity. Each floor member 15 is so laid that its parallel groove 16 and parallel groove 17 may be connected straight through adjascent floor members 15. Cut work, etc., of the floor members 15 become easy by using line grooves 74, 75 as a reference of length. Besides it becomes unnecessary to prepare and lay different components of size determined beforehand for excuting by a wall, etc. Accordingly, it also becomes unnecessary to perform lay-out work for setting beforehand the arrangement positions of the floor members and different floor members used by a wall, in the case of laying the floor members 15 on a floor surface. |
