Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a double floor structure in a clean room or the like.

In clean rooms in semiconductor manufacturing factories and the like, a double floor structure is adopted to facilitate dust-proofing work.

Figure 1 is a plan view showing a conventional double floor structure, and Figure 2 is a vertical cross-sectional view thereof. In the conventional double floor structure, a long waterproof sheet 2 is attached to a floor plate 1 such as a concrete slab. A waterproof floor is formed by placing a steel destal 6 on each corner of the specified dimensions of the floor panel 4, and a floating floor is formed by placing the floor panel 4 on the . The seismic performance is improved by reinforcing materials such as tie bars 5.

f- In the conventional double floor structure as described above, after the waterproof floor is completed using the long sheet 2, the steps for positioning the bottom deck 6 are made, the bottom deck 6 is assembled, and the floor panels 4 are laid out. Since the building was constructed with double floors, it was safe for multi-step work to be carried out by craftsmen of two or more professions. When anchoring the sundabe'destal 6 to the floorboard 1, the waterproof layer must be damaged, and even if repaired, its reliability is extremely low.Furthermore, when used in a clean room, etc., acidic The chemical resistance of K is extremely low.
,・Flooring when walking due to rising and floating of gunnel 1
There were drawbacks such as the generation of noise and the difficulty in cleaning due to seismic reinforcing materials.

This invention aims to improve the conventional drawbacks as follows.d)
A pedestal with 1tii1 seismic reinforcement ribs is integrated into a waterproof floor No. 1 material, and a floor 2 that engages with the pedestal is constructed.
A double floor structure that simplifies the work process, prevents floor panels from floating and cracking, and facilitates dust removal work by laying down flannel, which also ensures waterproof function and improves chemical performance. is intended to provide.

This invention has a waterproof floor sheet material that is attached to a floorboard, one vibration damping reinforcing rib, and a plurality of pedestals that are integrated with the floor sheet material, and a plurality of pedestals that are arranged to engage with the pedestals. It has a double floor structure characterized by having a floor nominelle that is floated to form a floating floor.

Hereinafter, the present invention will be explained with reference to embodiments of the drawings.

FIG. 6 is a plan view of a double floor structure according to an embodiment of the present invention before floor panels are installed, and FIG. 4 is a vertical sectional view after the floor panels are installed, which are the same as FIGS. 1 and 2. Symbols indicate corresponding parts by the same size.

The elongated sheet 2 is made of a waterproof sheet such as a soft plastic sheet, and is pasted onto a floor plate 1 such as a concrete slab, and has a plurality of solids 6 integrated therein.

The pedestal 6 is a molded product made of a hard plastic material such as reinforced plastic, and includes a substrate 3a that is joined to the long sheet 2, and a columnar body 6 that extends upward from the substrate 6a.
b, and seismic reinforcing ribs 6C formed vertically so as to be connected to these, and depending on the load-bearing performance value, reinforcement can be performed by embedding steel material or the like inside. The long sheet 2 and the final sheet 6 are integrated by welding or integral molding.

・The test board 6a is provided with a hole d for the anchor bolt 6, and after it is anchored to the anchor bolt floor plate 1, it is filled with sol material 7. A cross-shaped groove 6e is formed on the soil surface of the columnar body 6b, and four portions 6 are formed on the I11+1 wall of this groove e.

The floor 2-wall 4 is a plastic molded product with a square planar shape, and a protrusion i4a protruding downward is formed on its periphery so as to engage with the groove 6e of the destallet.
1. On the inner side of the tip of the protruding edge 4a, a rib 4b for preventing floating up is formed to engage with the recess b6f. Edge 4a
The ribs 4b may be provided over the entire circumference of the floor panel 4, and may be provided only at the portions corresponding to the grooves 6e, recesses, and portions 6f. The floor panel 4 has four corners facing each other, and the projecting edge 4a
:b- and the rib '4b are structured to engage with the groove 3e and the recess 6f.
It is integrated into the elongated sheet 2 so that it is arranged at the corner sound μ.

The method for forming the double floor structure is to form a waterproof floor by pasting the elongated sheet 2 on which the duplex destals 3 are integrated onto the floorboard 1. At this time, by joining the long notebooks 2 by welding 8, a waterproof layer can be formed. The elongated sheet 2 may be attached by simply laying it on the floorboard 1'', but it is preferable to fix it with an adhesive or the like. sundazudestal 6i
lJ: If necessary, insert the anchor bolt 6 through the hole 6d.
is embedded in the floorboard 1 and anchored, and the hole 6d at the top of the anchor bolt 6 is filled with a sealant 7 and sealed.

After forming a waterproof floor as described above, the floor ξ panel 4 is fitted from the top of the destal 6 using its elasticity so that the protrusion i4a and the rib 4b engage with the groove 6e and the recess 6f. , forming a floating bed to complete the double bed structure.

The double floor structure formed by above 2 has the destal 6 integrated into the long sheet 2 in advance at the factory.
The installation work on site becomes easy, and Anchor Porto 6
Even if holes are made, they can be easily sealed without compromising waterproof performance. Since the floor panel 4 is still engaged with the pedestal 6 in the installed state, there is no lifting of the floor panel 4 and generation of squeaks.

In addition, in [1] explanation, the pedestal integrated with the long sheet 2 - midestal was illustrated, but the floor panel 4
Any other structure is acceptable as long as it can support it.''

The means for securing the pedestal and the floor miner 4 are not limited to those described in L and M, but may also have other structures.The present invention is not limited to the clean roots of semiconductor factories, The present invention can be similarly applied to other double floor structures such as electronic computer rooms, precision machinery factories, etc., where wiring, air conditioning ducts, etc. are provided on the floor.

As described above, according to the present invention, the base B14 having seismic reinforcement ribs is integrated into the floor sheet 1-4N, and the floor panels that engage with the base are laid down. With this, the following effects can be obtained.

(1') On the stand 1, the floor pad 14 and the floor pad are integrated, and a waterproof layer can be formed by welding to the floor sheet material.

(When used in cuff room rooms, etc., cleaning and maintenance are easier than conventional ones.

■Can be made of plastic and has better chemical resistance than metal supports.

■When anchoring the pedestal, 2. There is no damage to the floor waterproofing, and the waterproofing of the top of the anchor bolt is easy.

■The pedestal that is integrated with the floor sheet can be made by simply arranging the sheet materials on the floor, gluing them to the floorboard, and welding between the sheet materials.
This can be easily done by using a hole-in anchor from the L part. Therefore, the conventional multi-step work by craftsmen of two or more professions, such as v) water application, summing, and post setting, can be completed in about 1, which saves labor.

■It is possible to prevent floor panels from lifting up and the generation of floor creaking noises when walking due to lifting, and it is also possible to minimize the difference in level between the joints between floor panels.
