Description

[Detailed Description of the Invention] This invention relates to a double floor construction method that increases heat insulation and sound insulation effects and improves livability in architecture, wooden buildings, etc.

Conventional double floor construction methods include (1) large joist method, (2) floor joist method, and ('3) foam material laying method, but each of these methods had major drawbacks. These construction methods will be explained below. ■ is the most common Y method, as shown in Figure 51, the large tension members 1 are fixed on the subfloor b at regular intervals with anchor bolts 2, etc. This construction method involves assembling joists 3 at regular intervals and pasting veneer 4 and finishing paulownia 5 on these joists to form one floor. There are many disadvantages such as (01) poor floor height, (c) moisture accumulates in the space between the lower floor and the upper floor, and it becomes a breeding ground for pests.

■ As shown in Figure 2, several supports 13 with anti-vibration combs 12 are attached to panels or systemized joists 11.
・-Floor 1) This is a method of construction in which the floor is placed on the floor 11, and has disadvantages such as (a) the floor height increases, and the space between the subfloor and the floor becomes a breeding ground for pests because moisture accumulates in the space between the floor and the floor. (2) As shown in Figure 3, form a layer of foam A2j on the subfloor b, and then paste it. Kei a to form the upper floor C by pasting the heavy 24 etc.
, it has the disadvantage of poor shielding properties.

The present invention is a double floor construction method that simultaneously eliminates the drawbacks of the above conventional construction methods and realizes comfortable living with a low floor height. This method is characterized by supporting 8 floors by laying plastic hollow plates directly on the subfloor or through a flat layer.

The structure of the sewage invention will be explained in detail with reference to the drawings. Fig. 4 is a longitudinal sectional view showing an example of a double floor formed by the construction method of the present invention, Fig. 5 is a perspective view of a hollow board, and Fig. 6 is a
It is a 11Ji plane view of line A and A in the figure. When constructing the double floor shown in Figure 3, first
[10] Wooden or plastic joists 32 are installed at one-foot intervals using bolts, concrete nails, glue, etc. After that, sand is spread on the subfloor to form a flat layer 33. At this time, the surface of the flat layer 33 is at the same level as the top of the joist material 32, but is not flat at a slightly higher level. After that, the hollow boards 31 are laid on the second part of the flat layer 33 and fixed to the joists 32 with nails, wood screws, etc. Finally, the plywood board 34 and the double layer 35 are sequentially pasted (ZJ) to the hollow board 31 to form the upper floor CF shadow.The hollow board 3j is made of plastic and is shown in Figs. 5 and 6. As shown in FIG. Not only that, but there is almost no risk of condensation, unlike traditional insulation materials such as foamed plastic and filled side materials such as glass coolers.

Regarding sound insulation, the air layer absorbs the sound energy, and the hole 3
], because it is dispersed in the longitudinal direction of a, it has a remarkable effect. Regarding strength 1. A sufficient result can be obtained by appropriately designing the plate thickness, hole size, and spacing. The rigidity is also much greater than that of conventional foam plus plastic frosting, and there is no risk of making squeaks. Appropriate plate thickness is about 5 to 25x. The type of plastic used as the material is not particularly limited, but polyethylene and polypropylene are suitable, for example.

The flat layer 33 is used when the subfloor is not flat (it is constructed to fill the gap between the double floor and the hollow board, but it also has the effect of increasing heat insulation and sound insulation.) In this case, sand is used. However,
The flat layer is not limited to this, and the flat layer may be formed of, for example, mortar, plaster, plaster concrete, or the like. If the subfloor is sufficiently flat, such as by directly pressing concrete, the hollow board can be attached directly on top of it using an adhesive, etc., without constructing a flat layer.

- The floor is supported by a hollow board, and as in this embodiment, it is common to apply a finishing layer 35 to the laminated plywood board 34. However, the veneer treatment 34 is not always necessary; for example, a finishing material such as a parquet block can be directly attached to the top of the hollow board. In addition, when using a laminate plywood board, it is convenient to mark the imperfections and laminate it to the hollow board prior to construction.

As mentioned above, the construction method of the present invention has a structure in which the double floor is supported by laying hollow boards with excellent heat and sound insulation properties. It is excellent, has little risk of condensation, and provides a comfortable living experience. In addition, in the conventional double floor construction method, in order to ensure comfortable living, the floor height from the 2nd floor to the 4th floor top surface was required to be at least 80 thresholds. According to the invention, this can be reduced to less than half, and the ceiling height of the living room can be increased accordingly, or the floor height of the building can be lowered to make it more economical.The construction method of the present invention is easy to construct. This also contributes to labor savings on site.
