Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides a method for installing a raised floor by forming a space on a floor base and laying floor panels on the floor base. Concerning the method of laying.

[Prior Art] There are two construction methods for laying floor panels on a floor base when constructing the raised access floor. The first construction method is a so-called laying method in which support legs are fixed to each of the four corners of all floor panels, and the floor panels with these four legs are arranged vertically and horizontally on a floor base. The second construction method uses support legs with panel pedestals that simultaneously support each corner of four floor panels gathered at one point. In this construction method, after drawing reference lines and arranging the support legs at the intersections of the grid, the corner portions of the floor panel are placed and fixed on the panel pedestals of the support legs, and the floor panel is laid. In addition, conventional general support legs have a base plate, and this base plate is glued to the floor base to fix the support leg to the floor base, and the corner part of the floor panel is attached to the panel holder of the support leg. It is fixed with bolts etc.

[Problems to be Solved by the Invention] The former laying method makes it easy to arrange the floor panels, but it is difficult to adjust the height depending on the unevenness of the floor base (unevenness). The height of the four support legs must be adjusted for each floor panel, and this height adjustment work is complicated. On the other hand, the latter panel pedestal method is more efficient because the height of the corners of four floor panels can be adjusted simultaneously by adjusting the height of one support leg, and it is also more efficient than the floor-standing method. Although it has advantages such as requiring only one-fourth the number of supporting legs, it also has other complications. That is, it is necessary to draw grid-like reference lines on the entire floor base surface, and this drawing work is complicated. In addition, since the support legs are placed on the floor base in advance, it is necessary to fix the support legs to the floor base so that the placed support legs do not move. For example, fix the support legs to the floor base with adhesive. In this case, the fixing work using this adhesive is complicated, and the adhesive requires time to dry, resulting in a problem of reduced construction efficiency.

The present invention was made against the above background, and an object of the present invention is to provide a method for laying floor panels for a raised floor, which allows floor panels to be laid efficiently.

[Means for Solving the Problems] The present invention solves the above problems by arranging rectangular floor panels on a floor base via support legs that simultaneously support the corner portions of four floor panels on panel pedestals. This is a method of laying floor panels for raised floors, in which floor panels are laid using four legs attached to each of the four corners of the floor panel. Three types of floor panels with legs are prepared in advance: a floor panel with two legs, in which a support leg is attached to each corner, and a floor panel with one leg, in which a support leg is attached to only one corner of the floor panel. First, set reference lines in two perpendicular directions at appropriate positions on the floor base surface, and then set one corner section at the intersection of the two reference lines and two sides along the two reference lines. , one of the four-legged floor panels is placed, and then, in two perpendicular directions along the two reference lines, the two-legged floor panels are placed on the side of the four-legged floor panel that was placed earlier. Place them in order from
In this case, the method of arranging the floor panel with 2 legs is to place the two corners of the floor panel with 2 legs that do not have support legs on the floor panel with 4 legs or the floor panel with 2 legs placed earlier. This is done by fixing it to the panel pedestal of the support leg, and then in the internal area surrounded by the two perpendicular areas, place the floor panel with one leg in order from the part closer to the intersection of the reference lines, and then How to arrange the floor panel with one leg,
The feature is that this is done by fixing the three corners of the floor panel with one leg that are to be placed without support legs to the panel pedestals of the three support legs arranged in an L-shape by the previously placed floor panel with legs. shall be.

[Function] In the above floor panel installation method, the right angle 2 along the reference line
In the direction area, the two corner parts without legs of the floor panel with two legs are supported by the panel pedestals of the existing 4# floor panel or the two support legs of the floor panel with two legs, so The legged floor panel is stabilized because its four corners are supported by the support legs.

In addition, in the internal area surrounded by the area in two right-angled directions along the reference line, 3
The four corner portions of the one-legged floor panel are supported by the panel pedestals of the three supporting legs of the existing three-legged floor panels in an L-shaped arrangement. It will be supported and stabilized.

The work of fixing the support legs 12 to the corner parts of the floor panel 10 is carried out as follows. That is, the work of fixing the support legs 12 to the corner parts of the floor panel 10 is carried out as follows. When the steel ball 18 is pushed in and fitted, the elasticity of the elastic grommet 19 causes the steel ball 18 to engage the elastic grommet 19 so that it does not easily come off from the elastic grommet 19, and thereby the corner of the floor panel 10 A support leg 12 is fixed to the section.

After preparing the above three types of floor panels A, B, and C,
Two reference lines p and q that are perpendicular to each other are set on the floor base 11 in advance. This reference line p.

Usually, q is preferably provided using two adjacent sides of the floor base surface (edges of the floor base surface), but it may also be provided by drawing lines in two perpendicular directions at the center of the floor base surface.

Next, three types of floor panels A, B, and C with legs are laid in the arrangement shown in FIGS. 1 and 5. First, one floor panel A with four legs is laid down along two reference lines ρ, If the two sides of the floor base surface where q intersect are set as the reference line, the corner part is located at the corner of the floor base surface (O), and the two sides are arranged along the two reference lines p and q. do.

Next, a floor panel B with two legs (B,,

□, 123 have already been prepared, so if the three corner parts without legs of this floor panel C1 with one leg are fixed to the three support legs 121, 122, 123, the arrangement of the floor panel C5 with one leg is fixed. Complete. The next floor panel C2 with one leg is
In the same manner as above, the three supporting legs 12 of the two-legged floor panels Bll, B, 2 and the single-legged floor panel C3 placed earlier
Fixed to. Repeat this process to create floor panels with one leg (CI, C2, C).

By sequentially arranging the parts C, , C, . . . from the parts closer to the reference line intersection O, the floor panels 10 can be laid over the entire floor base surface.

Note that reference lines p in two orthogonal directions set on the floor base 11,
If q is placed in the center of the floor base surface instead of on two sides, the floor panels are laid in the same way for the four areas divided by the reference lines p and q (from the reference line intersection 0 to By laying the panels in the directions of the respective arrows, the floor panel 10 can be laid over the entire floor base surface.

Normally, the vertical and horizontal dimensions of the floor base surface are not necessarily integral multiples of the size of the floor panel, so an odd space remains at the edge of the floor base surface relative to the size of the floor panel 10. Create rectangular floor panels with odd dimensions to fit the space and place them there.

To adjust the height of the floor panels 10 in the floor panel installation work described above, insert a screwdriver into the edge 16a of the support bolt 16 through the circular hole 21 formed at the corner of the upper plate 13 of the four floor panels 10, and use the screwdriver to adjust the height of the floor panel 10. In this case, the panel pedestal 17 is attached to the four floor panels 1.
0 and does not rotate, the panel holder 17 moves up and down according to the amount of rotation of the support bolt 16, and the height is adjusted.

In the above floor panel installation work, the corner part of the legged floor panel without legs is connected to the support leg 12 of the existing legged floor panel.
As mentioned above, the work of fixing the floor panel to the floor panel can be done by an extremely simple operation of pushing and fitting one elastic grommet at the corner of the floor panel 10 into the steel ball 18 on the panel holder 17. The workability of panel installation is good.

In the embodiment, the support bolt 16 is placed directly on the floor base 11, but as shown in FIG. 6, a base plate 23 may be provided at the lower end of the support bolt 16. Further, in this case, it is necessary to separately consider the m-ellipse for adjusting the height of the support bolt 16.

Furthermore, as for the means for fixing the corner portion of the floor panel 10 and the panel pedestal 17 of the support 1112, the elastic material grommet 19 provided on the floor panel 10 side and the steel ball 18 fixed to the panel pedestal 17 as in the embodiment are used. For example, simple bolts, T bolts, J bolts, etc.
Fixing means with bolts or other means may be used as desired.

Further, the floor panel may be rectangular instead of square, and may have a solid structure, for example, not limited to a hollow structure, but made of a single plate.

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

Since the support legs can be attached to the floor panel before placing the floor panel on the floor base, the efficiency of the work of placing the floor panel on the floor base can be improved and construction time can be shortened.

The reference lines for laying the floor panels are only the two reference lines in two perpendicular directions for the support legs of the four-legged floor panel that will be placed first. Since there is no need to provide a floor panel, the workability of laying floor panels is improved in this respect as well.

Further, when the fixing means of claim 2 is adopted as the means for fixing the corner portion of the floor panel to the panel pedestal of the support leg, the engagement hole on the floor panel side can be fixed to the panel cradle of the support leg. The fixing work can be done with a simple operation of pushing it into a ball, etc., and the efficiency of the fixing work is extremely good, so that the efficiency improvement by the floor panel laying method of the present invention is realized even more markedly.
