Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a floor structure in a house, and more particularly, to a floating floor structure in which a floor is formed at a predetermined height on a floor base.

[Conventional technology]

As a floor structure for a house, a direct-adhesion floor and a floating floor have been conventionally known. The direct-adhesive floor is one in which floor finishing materials are laid directly on the floor base, which is advantageous in terms of cost, and because the height from the floor base to the ceiling can be lowered, the number of floors in an apartment complex can be increased. However, there is a drawback in that the piping and wiring must be embedded in the floor base, and the floor base must be broken during repair.

On the other hand, a floating floor is one in which multiple columns are erected on the floor base at appropriate intervals, the floor base material is supported and fixed by the upper ends of these columns, and a floor finish material is laid on the floor base material. .
An example of this will be explained in more detail with reference to FIG. 3, which shows a dry double floor as an example. It is composed of wood materials such as particle board and plywood, or inorganic materials such as cement and calcium silicate and cut into appropriate sizes. The floor base panel 1 is prepared, and is made of a plurality of metal or hard plastic on the floor base 2 at appropriate intervals so as to support the four corners of the floor base panel 1 at their upper ends. The pillar 3 is erected. In addition, at the corners around the room, a joist 5 is laid via a bundle 4 so that the upper surface of the joist 5 is at the same level as the upper end surface of the pillar 3. The floor base panel 1 near the wall 6 is laid so as to support the four corners by the joist 5 and the pillars 3, and the other floor base panel 1 is supported by the pillars 3, and the pillars 3 and the pillars are laid by nailing or bolting. Secure to joist 5. Next, the sacrificial laminating boards 7 are spread over each floor substituting panel 1 so as to straddle the joints of the floor substituting panels 1, and the sacrificial laminating boards 7 are fixed on the floor substituting panels 1 by nailing or the like. Finally, by laying the finishing floor material 8 on the laminating board 7, the floor board is integrally constructed. The lower ends of the columns 3 are fixed to the floor base 2 by bolts (not shown) or the like via a vibration absorber 9 such as elastic rubber. A cushion material 10 made of elastic rubber or the like is interposed on the end surface of the floating floor that abuts against the wall 6 in order to prevent squeaking caused by floor vibration. The wall edge of the floating floor may be covered with the lower end of the decorative member 11 provided so as to project from the surface of the wall 6 into the room as shown in the figure, or the wall edge of the floating floor of the wall 6 may be covered. You may make it form the eave-shaped step part which fits the surface which contacts a part, and may be covered with this step part.

In such a floating floor structure, pipes 12 such as water supply and discharge pipes and gas pipes or wirings 13 can be arranged on the floor base 2, and the pipes and wiring can be changed without breaking the floor base 2. However, even if the finishing floor material 8 is laid freely so that it can be removed, the floor base panel 1, the scraping board 7, and the finishing floor material 8 located on the piping or wiring are destroyed in order to change the piping or wiring. There is a need.

On the other hand, floating floors called free access floors are often used in office floors such as computer rooms and offices. This floating floor has a side of 30 to 100 cm
In this case, a 40 mm floor panel with a thickness of 15 is supported by columns that are erected on the floor base, similar to the dry double floor above, and a laying finishing material such as tile carpet or punch carpet is laid on it. Is. The floor panel is made of, for example, a wood material such as particle board or a panel material made of an inorganic material such as calcium silicate.
In such a floating floor, the floor base can be easily exposed by peeling off the floor covering and removing the floor panel underneath, so it is extremely easy to change the piping and wiring as described above. be able to.

[Problems to be solved by the device]

In order to solve the problems of floating floors for residential use as described above, we think that it would be better to use this free access floor as it is for residential use. It was actually constructed, and a comparative evaluation with the conventional floating floor for residential use shown in Fig. 3 was performed. As a result, it was found that when a free access floor was laid in the house, the walking feeling was poor. This is because in the case of a house, the floor panel under load is deformed and vibrates independently because the user walks with bare feet or slippers, and the foot feels the vibration. As you walk with your shoes on, you will not feel such deformation or vibration. Moreover, the impact noise is great when the article is dropped. This is because each floor panel has a small area and can not absorb shock sufficiently, and when comparing the living room with the office, the ceiling height is lower than the office and the quietness is much higher in the house. It is thought that this is because it is easy to hear the sound echo and impact sound. From this, it was found that even if the free access floor was simply converted into a residential building, it could not be put to practical use.

Therefore, an object of the present invention is to provide a floating floor structure for living that allows easy replacement and removal of wiring, piping, etc., has a good walking feeling, and has excellent sound insulation such as floor impact sound.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention installs a plurality of floor base panels on a floor base through a supporting member, and lays a throw-on ply board on the entire surface of the floor base panel to integrate the floor base panels. In the floating floor structure for living in which the floor board is laid at a predetermined height position on the floor base by arranging the floor board on the floor board by fixing the floor board at least on one side edge thereof. Is laid apart from the wall by a predetermined distance, and a plurality of pit panels are laid in the gap at the same level as the floor plate in a detachable manner, and there is a slight gap between the pit panel and the edge of the floor plate. The feature is that a gap is provided.

In this case, it is preferable that the gap between the pit panel and the floor plate be filled with a vibration absorber made of an elastic body.

[Action]

According to this structure, the floorboard is laid integrally except for the wall where people normally do not walk or stop, so the floorboard is deformed or vibrated due to the impact when walking or dropping an object. Since it will be received by the entire floor plate, it will be possible to obtain a walking feeling equivalent to that of a conventional floating floor structure, and to suppress impact noise to a low level. The floor near the wall is composed of a removable pit panel, so if you install piping and wiring under the pit panel, you can easily inspect and change the piping and wiring by removing the pit panel. be able to. Since a slight gap is provided at the boundary between the pit panel and the floor plate, vibration applied to the pit panel and the floor plate will not be transmitted to the floor plate or the pit panel.

Further, by filling the gap between the pit panel and the floor plate with the vibration absorbing material, the vibration generated from either of them can be absorbed, so that the generation of vibration can be prevented more reliably.

〔Example〕

The invention will be described below with reference to an embodiment shown in FIGS. 1 and 2. The constituent elements that can be regarded as the same or substantially the same as those in the above-described conventional example are designated by the same reference numerals, and detailed description thereof will be omitted.

In Fig. 1 and Fig. 2, for example, 10 to 15 cm from the wall 6
30 to 100 cm on each side of the entire gap.
A plurality of floor base panels 1 having a thickness of 15 to 40 mm are laid out. Each floor base panel 1 is supported from the floor base 2 with a proper gap therebetween via the support columns 3 and the vibration absorbing material 9 as in the conventional case. Each strut 3 facing the gap on the wall 6 side
A strip-shaped frame member 21 is provided at the upper end of the so as to support each floor base panel 1 on its upper surface and to horizontally project from the side edge of each floor base panel 1. The frame member 21 is made of particle board, plywood, metal plate, hard plastic plate, or the like. Therefore, each pillar 3 supporting the floor base panel 1 facing the gap on the side of the wall 6
Is lower than the remaining columns 3 by the thickness of the frame member 21.

On each floor base panel 1, a laminating board 7 is spread over the entire surface so as to straddle the joints of the floor base panels 1, and each floor base panel 1 is nailed or the like.
Is fixed integrally with the sewage laminating board 7, and the finishing floor material 8 is laid on the sewage-bonding board 7. In this way, the floorboard is integrally configured.

In the same way as in the conventional case, a perimeter joist 5 is laid around the circumference of the wall 6 through the bundle 4 so that the upper surface thereof is at the same level as the upper end surface of the frame member 21. Between the girder joist 5 and the frame material 21, a metal plate, particle board, plywood,
A plurality of pit panels 22 composed of a metal plate, a hard plastic plate, a cement plate, a calcium silicate plate, etc. are removably mounted. The pit panel 22 has a width that is slightly shorter than the gap between the wall 6 and the floor base panel 1, and the thickness thereof is set to be approximately equal to the total thickness of the floor base panel 1 and the laminating board 7. . A finishing floor material 23 similar to the finishing floor material 8 is attached to the upper surface of each pit panel 22. As shown in FIG. 2, any one of the pit panels 22 or a plurality of pit panels 22 located at appropriate intervals are provided with a wiring device 24 such as an outlet connected to the wiring 13. Installed.

Cushioning material between the wall 6 and the side edge of each pit panel 22
A cushion material 25 similar to the cushion material 10 is inserted in the gap between each pit panel 22 and the floor base panel 1. With these cushion materials 10 and 25, each pit panel 22 is placed between the joist 5 and the frame material 21 without rattling. Incidentally, reference numeral 26 in FIG. 1 is a window.

In the floating floor structure configured as described above, since the floor of the portion where the person moves is laid with the plurality of floor base panels 1 and fixed integrally with the laminating board 7, Vibration caused by an impact when an object is dropped is attenuated while being transmitted on a large area of the laminating board 7, so that the same feeling of walking and shock absorption as a conventional floating floor for a house can be provided. On the other hand, since each pit panel 2 is located in a narrow space near the wall 6, people pass by in daily life,
Since it is not a place where things will fall, spreading a small pit panel 22 will impair the feeling of walking a little,
Even if the impact noise from falling objects becomes high, they are rarely felt in daily life. Further, even if the vibration is transmitted to the end surface on the laminating board 7, it is possible to prevent the cushion material 25 from absorbing the vibration and transmitting to the pit panel 22.

In the above-described embodiment, the cushion material 25 is inserted in the gap between each pit panel 22 and the floor base panel 1, but the cushion material 25 is not always necessary, and the discarding board 7 is used.
A slight gap may be provided so that the vibration of the above is not transmitted to each pit panel 22. In this case, the end portion of each pit panel 22 on the frame material 21 side may be detachably fixed to the frame material 21 by, for example, screwing or the like to prevent backlash. Further, the floor base panel 1 may be one obtained by curing a hydraulic material such as mortar or concrete in a mold.

[Effect of device]

As described above, in the floating floor structure for living of this invention, the floor board is laid integrally except for the wall where people normally walk or do not stop, so when walking or dropping things. The deformation and vibration of the floorboard due to the impact at the time will be received on the entire floorboard, and the walking feeling equivalent to that of the conventional floating floor structure can be obtained, and the impact noise can be suppressed low. In addition, the floor near the wall is composed of removable pit panels, so if you install piping and wiring below these pit panels, you can easily inspect and change piping and wiring by removing the pit panel. It can be carried out. Since a slight gap is provided at the boundary between the pit panel and the floor plate, vibration applied to the pit panel and the floor plate will not be transmitted to the floor plate or the pit panel.

Furthermore, by filling the gap between the pit panel and the floor plate with a vibration absorbing material, the vibration generated from either the pit panel or the floor plate can be absorbed without being transmitted to the other, so that the generation of the vibration is more reliable. Can be prevented.
