Description

Description: TECHNICAL FIELD The present invention relates to a floor member that constitutes a floor that does not transmit various vibrations or swings caused by an earthquake or various mechanical devices in various buildings. It is a thing.

[Prior Art] A floor member for seismic isolation has been proposed in which a plurality of legs are hung on the lower surface of a floor plate and an elastic material is attached to the lower ends of the legs.

[Problems to be Solved by the Invention] The floor member described above can obtain a slight seismic isolation effect, but since the elastic material is simply attached to the lower surface of the leg, the effect is not high, and the structure is low. It is not very practical. In addition, the seismic isolation effect against horizontal vibration is not sufficient.

[Means for Solving the Problems] The gist of the present invention is that a supporting leg having a lower end formed as a smooth surface is hung in a well-balanced manner on the lower surface of the substrate, and the lower surface of the substrate is provided with The axial length is long, while the diameter is small, and in addition, elastic support shafts of one or more diameters are suspended in a well-balanced manner for each diameter, and the support shaft is the thinnest. The diameters are set to be the longest, and the diameters are made shorter as the diameters gradually increase, and further, the substrate is slidably face-to-face bonded at the lower end of the support shaft on a floor plate having an upper surface as a smooth surface. It is a floor member.

The substrate can be made of any material such as wood, plastics or metals. Plastics are easy to use because they have good moldability. It is convenient for handling that the substrate is already formed in a square shape. Further, its size may be determined depending on the convenience of handling. 30 cm to 50 cm square is suitable.

Appropriate makeup can be applied to the upper surface of the substrate as needed. For example, a vinyl sheet, a plastic sheet, or the like may be attached, or a wooden board material may be attached. Sheets or panels of suitable materials may be attached or other suitable makeup may be applied in harmony with other elements in the room.

The supporting legs are hung from the bottom surface of the substrate in a well-balanced manner. For example, it is suitable to hang down from the four corners of the lower surface of the substrate, the middle and center of each side, and the like. The support leg can be formed in a prism or the like, but is preferably formed in a column. In addition, it is appropriate that the support leg is molded integrally with the substrate by using plastic. The smooth surface at the lower end of the support leg is formed by forming a film of plastics having a low friction coefficient. Of course, other suitable conventional techniques can be adopted for the construction of the smooth surface.

As described above, the support is formed by suspending one or more kinds of shafts having different shaft diameters. In the case of one diameter, a plurality of support legs, which are slightly longer than the support legs, for example, about 1 mm, are formed so as to hang from the lower surface of the multiple substrates. When the support shaft is composed of two or more kinds of diameters, as described above, the smallest shaft diameter should be configured to the longest, and the shaft diameter should be gradually decreased as the shaft diameter increases, for example, shortened by 1 mm. Constitute. The number of types having different shaft diameters is not limited. It can be set to any number of types.

A plurality of support shafts having respective diameters are formed, and the support shafts having respective diameters are arranged in a well-balanced manner on the lower surface of the substrate. In this way, the brush-like appearance is formed.

Incidentally, it is suitable that the support shaft body is integrally formed of plastic with the substrate, like the support leg. The plastic has some elasticity. If necessary, the lower end of each of the support shafts is also treated to make it a smooth surface.

On the other hand, as the base plate, like the base plate, wood, plastics, metals or the like can be freely selected and adopted. This is different from the substrate, and it is more convenient in construction to construct a large-sized plate body.

Similar to the smooth surface formed on the lower surface of the support leg, the upper surface of the floor plate is formed with a film of plastics having a low friction coefficient to form an appropriate smooth surface. Of course, any suitable conventional technique can be employed.

[Operation] Therefore, the floor member of the present invention can be used as follows.

First, a laying board is laid on the floor base inside the building. Cover the upper surface of the entire floor base with a floorboard by spreading an appropriate number of it. The floor plate is fixed on the floor base with an adhesive or the like.

Next, the substrates are sequentially placed on the floor plate. The lower surface of the substrate faces the upper surface of the floor plate, and the lower end of the longest support shaft is slidably joined to the floor plate. In the vicinity of the inner wall of the room, a slight gap is placed between them. In this way, the substrate is placed except for the above-mentioned gap, and a suitable cushion member is inserted into the above-mentioned gap to form the floor.

The floor above can obtain a cotton quake effect as follows.

When vibration or rocking such as an earthquake occurs, the floor plate naturally vibrates or rocks together with the floor base.

By the way, when heavy articles are not placed on the floor surface, the substrate is in contact with the floor plate at the lower end of the longest support shaft. That is, the lower end of the support shaft having a small contact surface is in contact with the smooth surface of the floor plate. Therefore, the maximum frictional force that can be transmitted between the lower end of the support shaft and the smooth surface of the floor plate is extremely small, and slippage easily occurs due to vibration that is not so strong, and the vibration transmitted to the floor plate is not transmitted to the substrate. .

When the vibration or swing becomes large, the longest supporting shaft becomes slightly bent and the lower end of the supporting shaft of the next length comes into sliding contact with the sliding surface of the floor plate. Supported.

When the vibration or the like further increases, the substrate is supported by the supporting shaft having the next length, and finally the lower ends of the supporting legs slidably contact and support the sliding surface of the floor plate.

Therefore, slippage easily occurs from a small stage of vibration or rocking, and vibrations on the floor plate side are not transmitted to the substrate side. As the vibrations increase, the supporting shaft body that contacts the smooth surface of the floor plate increases in sequence. It will be replaced by one with a diameter, and finally it will be supported in a sliding state by the support legs. Therefore, from the stage of small vibration to the stage of large vibration, seismic isolation effect occurs,
And the bearing capacity is also sufficient.

When some heavy equipment is placed on the floor, only the longest support shaft will bend slightly or the next support shaft will bend slightly depending on its weight. Then, the lower end of the supporting shaft having the next length comes into contact with the smooth surface of the floor plate.

In the event of vibration or swaying such as an earthquake, the supporting shafts that slidably contact the sliding surface of the floor plate sequentially change from the above stairs, depending on the magnitude of the vibration, and move relative to each other on the sliding surface. It seismically isolates itself as it slides.

Therefore, as described above, the substrate can maintain a stationary state or a state close to a stationary state regardless of the magnitude of vibration or swing transmitted to the floor plate.

Therefore, the floor configured by this floor member does not easily transmit vibration or swing even in the event of an earthquake or the like. It is especially suitable as an indoor floor where equipment that is sensitive to vibration is installed.

The floor composed of this floor member is normally supported by a support shaft which is hung on the lower surface of the substrate, and therefore has elasticity and a good walking feeling.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.
