FIG. 6 is a perspective view of a partial cross section of the corner support leg. FIG. 7 is a perspective view of a main part of a partial cross section of the corner support leg. FIG. 8 is a perspective view of a partial cross section of the double floor panel. FIG. 9 is a side view of the corner support leg. FIG. 10 is a side view of the support leg for the border portion.

The double floor is composed of a floor panel, corner supporting legs, border supporting legs, and stringers.

[0006] In FIGS. 6 and 9, a corner supporting leg D has a base portion 1, a supporting portion 2, and a head portion 3. The corner supporting legs D are members that support a portion where four vertexes of four floor panels, which are square double floor panels, become one, and are used in places other than the walls of the building floor. .

[0005] The base 1 is substantially a plate, and a support 2 is provided upright at the center. At the upper end of the support section 2, a head section 3 is provided. The head portion 3 has a main body formed by projecting a cross-shaped partitioning protrusion 3b from the upper surface of the substrate 3a, and has recesses 3c at four corners. In addition, the support portion 2 can adjust the height of the head portion 3.

As shown in FIG. 7, a stringer 4 which is a horizontal member having a U-shaped cross section is engaged with the partitioning projection 3b from all sides. The stringer 4 is provided between adjacent corner supporting legs D, and a plurality of stringers 4 and corner supporting legs D are provided continuously in a row and a column to form a lattice-shaped support.

[0007] A floor panel 5 having a predetermined thickness T as shown in FIG.
Is arranged in a space surrounded by the stringers 4 on all sides, the flanges are supported by the stringers 4. The upper surface of the flange 5a is flush with the main body of the floor panel 5. The flange 5b at the top of the floor panel 5 is
It is supported by the stringer 4 and the corner supporting legs D.

On the other hand, near the wall of the floor of the building, the floor panel is directly supported by the supporting leg E for the border portion without using the stringer 4.

The support leg E for the border portion is a member for supporting the floor panel near the wall, and has a base portion 6, a support portion 7, and a head portion 8 as shown in FIG. The head 8 has a flat upper surface, and directly contacts the bottom of the floor panel 5 to support the floor panel 5 with the surface. Therefore, the support leg E for the border portion is shorter in length in the height direction than the support leg D for the corner portion by the length obtained by subtracting the thickness of the flange portion 5a from the predetermined thickness T of the floor panel 5. It is said.

As described above, the support leg E for the border portion directly supports the floor panel at the wall, and the stringer provided between the corner support leg D and the corner support leg D at the portion other than the wall. 4 is floor panel 4
By supporting the flange portion 4a, a double floor is formed.

However, the support structure for a double floor panel shown in FIGS. 6 to 10 described above has a support leg E for a border portion for a wall and a support leg E for a portion other than the wall. Two types of support members, namely the corner support legs D, are required.

Also, the height of the corner portion support leg D in the height direction is adjusted by adjusting the height of the head portion 3 with the support portion 2 of the corner portion support leg D, and the border portion support leg E is formed. However, since the adjustable length is not so long, the height of the upper surface of the floor panel 5 from the floor when the floor panel 5 is placed on the head 3 is equal to the height of the head 3 and When the stringer 4 supports the flange portion 5a of the floor panel 5, it is often higher than the height of the upper surface of the floor panel 5 from the floor and cannot be adjusted by the height of the partitioning projection 3b in many cases. , Cannot be combined.

[0013] Therefore, there are problems that the number of support members becomes two, which necessitates sorting of parts during construction work, which lowers the efficiency and requires time for inventory management.
