2. Description of the Related Art In recent years, as a finishing material for floors, a direct-adhesive type wooden floorboard has been favored and is widely used in houses and the like. This wooden floorboard is made up of a large number of rectangular floorboards, which are connected to each other by means of so-called “sanehagi” means for fitting a groove and a ridge provided on the outer periphery of the floorboard and laid on the upper surface of the floor base. FIG. 9 shows an example thereof.
Reference numeral 50 is a floor base, 51 is a floor plate material, 52 is a groove, and 53 is a ridge. As shown in the figure, first, one floor plate material 51
Is placed on the floor base 50. And the floor board material 51
The floor plate material 51 is fixed to the floor base 50 by driving a nail 54 or the like into the lower protruding piece 53 that forms the concave groove 52. After that, the protrusions 53 of the adjacent floor plate materials 51 are fitted into the groove 52, and the groove of the floor plate material is nailed in the same manner as described above. By repeating this, a large number of floor board materials are connected to each other and laid on the floor substrate.

However, in the wooden floorboard having such a structure, when fixing the floorboard 51 to the floor base 50, it is necessary to hammer a nail into the groove 52, which makes the work difficult. Therefore, the nail 54 had to be driven obliquely from the outside as shown in the figure. I also had to prepare long nails.

By the way, since such a wooden floorboard is a relatively hard material, it is difficult to buffer the impact sound generated by walking on the floor or hitting an object, and in an apartment such as a condominium. , The noise downstairs is a problem.

Therefore, in order to absorb the noise, there is known a soundproof wooden floor board material in which a cushion material having an appropriate thickness is arranged between the floor base material and the floor board material. However, there is also a problem in that the floor plate members are bent at the time of walking so that the floor plate members are rubbed with each other to generate a squeaking noise.
