Furthermore, since each floor plate member 50C, 50D is fixed to the joist member 10 by the fastening member 60, even without unevenness (tongue), positional deviation is less likely to occur. Furthermore, the adjacent floor plate members 50C, 50D are not fitted into each other by unevenness (tongue), and can be attached and detached independently from the joist member 10. Therefore, for example, if damage occurs to the floor plate member 50C, only the damaged floor plate member 50C can be easily removed and replaced, and there is no need to remove the floor plate member 50D.

Since the support member 20 in this embodiment is made of elastic rubber or the like, a large frictional force acts between the floor foundation GL and the base portion 21 based on the load of the beam member 10. Therefore, the structure is such that positional deviation is unlikely to occur simply by placing the base portion 21 on the floor foundation GL.

  • floor plate member 50F After removing floor plate member 50F from beam members 10A-10D, a new floor plate member 50 is placed in place of the removed floor plate member 50F and attached to beam members 10A-10D using fastening members 60 and cover members 70. In this way, it is possible to easily replace only the floor plate member 50F to be replaced. In other words, floor plate member 50F can be replaced without affecting floor plate members 50G1-50G6 arranged adjacent to floor plate member 50F, beam members 10, and support members 20. This makes it possible to significantly reduce the man-hours and costs required for the replacement work.
  • FIGS. 9A and 9B are diagrams explaining another example of a method for replacing a floor panel member 50.
  • a floor panel member 50F is arranged to span four beam members 10A to 10D adjacent to each other in the second direction, and a crack (fissure) has occurred in the floor panel member 50F.
  • the method of Figures 9A and 9B allows only the smallest section of the floor panel member 50F to be replaced to be replaced, further reducing the cost of replacement materials. For example, if the length of one floor panel member 50 in the second direction is about 4m, replacing the entire 4m floor panel member will increase the material cost of the floor panel member involved in the replacement. In contrast, if only the section between two joists 10, 10 adjacent in the second direction (about 600mm) is replaced, it is possible to reduce the material cost of the floor panel member. In this way, the floor structure of this embodiment allows for greater maintainability compared to conventional floor structures.
