2. Description of the Related Art A conventional example of constructing a dry double bed (Japanese Patent Laid-Open No.
-305441, 7-305442, 8-13
No. 752) will be described with reference to FIG.

[0003] Fig. 10 (b) is a perspective view of a bearing material used for this construction, and Fig. 10 (a) is a perspective view showing a construction method. The support member 1 has a nut 3 provided on a receiving plate 2, an upper end of a support bolt 4 is screwed to the nut 3, and a rubber pedestal 5 is fitted to a lower end of the support bolt 4.

As shown in the drawing, the upper end of the support bolt 4 is retracted from the upper surface of the receiving plate 2.

[0005] In order to construct the panel 6 on the slab or the base floor 7 so as to form a double floor using the support 1, the arrangement position of the support on the slab or the base floor 7 is determined by ink marking or the like. Then, the support members 1 are erected on the slab or the foundation floor 7 at exactly predetermined intervals. Next, the panels 6 are laid out so that the edge of the panel 6 covers one half of the upper surface of the receiving plate 2 of the support 1. At this time, if necessary, the receiving plate 2 and the panel 6 are temporarily attached with an adhesive sheet (not shown). Next, the edge of the adjacent panel 6 is placed and laid on the other half of the receiving plate 2. When arranging panels 6,
A gap d is provided between the panels 6. After laying and arranging the panels 6, the driver is inserted from the gap d and the support bolt 4 is turned to adjust the level. Then, after pouring an adhesive into the top surface of the support bolt 4, a material 8 such as a sheet or a floor material is applied on the panel 6.

[0006]

The conventional construction method described above has the following various disadvantages.

[0007] It is necessary to arrange the support materials 1 on the slab or the foundation floor at a predetermined pitch. However, it takes time and effort to position the support materials, and it takes much time to arrange a large number of support materials. Poor construction efficiency.

The overlapping margin between the receiving plate 2 of the supporting material and the panel 6 becomes uneven, and the panel 6 may come off from the receiving plate 2 due to an earthquake or the like.

During the construction, the panel 6 is loaded on only one half of the receiving plate 2 of the supporting material erected on the slab or the foundation floor, so that the supporting material 1 is easily inclined and is adjacent to the other half. This inclination is not eliminated even after the panels are loaded, and a step is likely to occur between the adjacent panels 6 and 6.

In some cases, the width of the gap d is not uniform, and the large gap d hinders the laying of the floor finishing material. Conversely, d is too small, so that the driver cannot be inserted into the gap d and the level cannot be adjusted. .

It is conceivable that the receiving plate 2 is bonded to the panel 6 in advance, but even in this case, the width of the gap d cannot be made constant. When adjacent panels come into contact with each other, floor noise may occur due to friction between the panels.
