Description

Description: TECHNICAL FIELD The present invention relates to a floor member to be used in a room equipped with various equipments to be protected against earthquakes and other vibrations in various buildings. Is.

[Prior Art] Conventionally, there are various floor members. For example, tile floor materials and panel floor materials. The former is used by adhering it to the base with an adhesive, and the latter is constructed by nailing the joist with a nail.

Further, the following technique proposed by the present inventor is presented for reference, though it is not a known technique.

This is a floor member in which a space is formed inside the substrate, and a liquid which is less than its capacity is enclosed in the space (Japanese Patent Application No. 63-82460).

[Problems to be solved by the invention] As described above, the conventional floor member is of a type that is fixed to the floor base by various means in any case, and the building itself does not vibrate due to an earthquake or the like. When it occurs, it naturally vibrates with it.

On the other hand, the above-mentioned floor member proposed by the present inventor is a floor member which itself has a function of damping vibration. Therefore, if it is used over the front surface of the floor of a building, it is possible to considerably dampen vibrations such as an earthquake transmitted to the building.

The former, however, has no effect of damping vibrations such as earthquakes, and is therefore unsuitable as a floor member for a room in which various devices to be protected from vibrations are installed.

On the other hand, the latter is convenient because it has a function of damping the vibration. However, since the latter floor member is fixed to the floor base and tries to damp the vibration of the building through the floor base, there is a sufficient effect when it is applied to only a part of the floor of the building. In some cases, you cannot get it.

The present invention is intended to provide a floor member that can have a function of damping vibrations only in a specific part of a building or a room even if the floor member is installed.

[Means for Solving the Problem] The gist of the present invention is to combine an upper plate and a lower plate, wherein the upper plate has a leg body having a space inside at the center of the lower surface of the upper plate so as to project downward. The space is filled with a liquid less than its capacity, and a smooth surface is formed at the lower end of the leg, while the lower plate is a smooth surface facing the smooth surface of the leg on its upper surface, The floor member has an elastic material on the lower surface.

The upper plate and the lower plate may be made of wood, plastics, metals, or any other free material. As for the upper plate, plastics are actually easy to use because they have good moldability. As for the lower plate, it is sufficient to form a flat plate, so the formability does not matter so much. The planar shape of the upper plate is not particularly limited, but like a general floor member,
For the convenience of construction and other reasons, it is suitable to form a substantially flat square or rectangular shape. The size may be determined according to the convenience of handling. If it is a plane square,
About 30 cm to 50 cm square is suitable. The lower plate may have substantially the same plane shape and dimensions as the upper plate.

The decorative plate may be directly attached to the upper surface of the upper plate, but it is appropriate to bond a suitable plate material having the same plane shape, for example, a veneer plate, and the decorative plate thereon. Is. It is appropriate that the plate material such as the veneer plate is joined so that the two adjacent two sides slightly project from the edge of the upper plate and the other two sides recede from the edge of the upper plate.

Further, it is preferable that the upper plate is provided with a connecting means to be adjacent to the upper plate when the upper plate is arranged on the floor base. For example, as described above, when the upper plate is formed into a flat quadrilateral, the adjacent two sides are provided with the protrusions, and the other adjacent two sides are provided at the positions corresponding to the protrusions. For example, a notch with which the protrusion can be engaged is configured.

In such a configuration, when the upper plates of the adjacent floor members are joined at the sides while engaging the protrusions and the notches, the protrusions are formed by the plate members joined to the upper plates of the adjacent floor members. It is prevented from moving upward. On the other hand, the downward movement is blocked by the floor base.

The legs may be formed in a prismatic shape or a cylindrical shape. A columnar shape that is uniform in any direction on the horizontal plane is preferable. For example, when the upper plate is a square plane, the diameter is appropriately about 7/10 of the length of one side thereof. However, it is not limited to this. Height is 50
Around mm is suitable. Of course, this size is not intended to be limited to this. When the leg body is integrally molded with the upper plate by a plastic material, the leg body may be molded into a cylindrical shape having a closed bottom surface and an open top surface. In this case, the tubular leg body serves as the space. As described above, when the plate member is joined to the upper plate, the space is closed.

A polytetrafluoroethylene resin or other resin having a small friction coefficient is arranged on the lower surface of the leg to form the smooth surface.

In addition, it is preferable that the leg body includes a pair of partition walls provided on the lower surface of the upper plate and in parallel with each other so as to be in contact with the leg body. When this floor member is installed on a base, it is the purpose of forming a protective passage for piping, wiring, etc. between adjacent floor members.

Inside the pair of partition walls, there are a pair of auxiliary walls provided on the lower surface of the upper plate, each of which is in contact with the leg body, and both ends are connected to the pair of partition walls at an angle of 90 °. Auxiliary wall will be arranged.

As described above, an appropriate liquid is directly put in the space, or a tank in which the liquid is sealed is charged and the liquid is indirectly put in the space. Then, when using the above-mentioned plate material, the plate material is joined to the upper surface of the upper plate. Adhesion, screwing or the like is appropriately selected as the connecting means for the upper plate and the plate material. Instead of the tank, a liquid may be sealed in a plastic film and placed in the space.

The shape of the space and the like must be limited mainly by the shape of the legs, but is not limited to a special shape. It is preferable that the inner wall of the above-mentioned space is formed in a plane circular shape having the same distance from the center in the radial direction as much as possible. Therefore, as described above, when the tank in which the liquid is sealed in the space is loaded, it is convenient to configure the tank to have a circular planar shape.

Various types of liquid can be adopted as the liquid. A relatively viscous liquid is suitable. Further, since it is used for a building, it is preferably nonflammable. The easiest way is to use water. As the water, it is suitable to use distilled water which does not easily rot or a mixture of preservatives.

In practice, it is appropriate that the liquid be enclosed in the space or in a tank charged into the space in an amount of about half or less of its volume. More preferably, it is about 1/3.

On the upper surface of the lower plate, the same polytetrafluoroethylene resin as that on the lower surface of the leg is arranged to form a smooth surface. An elastic material such as synthetic rubber is arranged on the lower surface. Although the elastic material may have a simple plate shape, there is no problem, but it is more preferable that the elastic material is formed into a "gourd" shape having upper and lower surfaces as flat surfaces and these are arranged at the four corners and the center of the lower plate.

[Operation] However, the floor member of the present invention can be used as a floor for preventing vibration by forming a floor by continuously arranging it on a floor base.

The floor base is naturally made smooth, and the floor member is constructed and arranged on the floor base. First, the lower plate is arranged on the floor base with the smooth surface facing upward, and the upper plate is arranged on the smooth surface with the lower surface of the leg body facing the smooth surface. Thus, the floor members are sequentially arranged.
When the connecting means is configured, the adjacent floor members are arranged while being connected to each other.

The floor member is installed around the inside of the room with a slight gap between it and the wall surface, and a cushion member is inserted into this gap.

However, when a vibration such as an earthquake is applied to the floor, the upper plate as a whole tries to maintain a stationary state due to inertial force, and this has smooth surfaces on the lower surface of the leg and the upper surface of the lower plate. When they slide on each other, they tend to be retained despite the vibration of the lower plate that accompanies the vibration of the building. However, since the smooth surfaces formed on the lower surface of the leg and the upper surface of the lower plate cannot be perfect smooth surfaces, that is, smooth surfaces having a friction coefficient of 0, in reality, the upper plate as a whole does not Upon receiving the transmission, some vibration must be generated.

In this way, when the entire upper plate starts to vibrate slightly, the liquid enclosed in the space of the legs acts to prevent the vibration, and the entire upper plate including the legs remains stationary. try to. That is, this is because the inherent vibration frequency of the liquid is lower than the frequency of vibration due to a general earthquake or the like. Specifically, liquid does not easily resonate with vibration such as an earthquake, and despite the vibration of the upper plate,
In order to maintain the stationary state, the liquid collides with the inner wall of the leg body space in both strokes of the reciprocating vibration, which is an action opposite to the direction of the vibration. This controls vibration.

As described above, since the liquid must be able to move relatively in the space inside the leg, the amount must be less than the volume of the space.

In this way, the upper plate can maintain a substantially stationary state in spite of the vibration of the building including the lower plate, and the floor composed of these floor members can maintain a substantially stationary state. Is.

Since an elastic material is arranged on the lower surface of the lower plate, the floor formed by this has a soft walking feeling.

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

As shown in FIG. 1 and FIG.
At the center of the leg 2, a leg 2 protruding downwardly is formed into a cylindrical shape with an open top and a closed bottom. That is, the leg 2 is formed integrally with the upper plate 1 by plastic. The inside of the leg body 2 opened on the upper surface of the upper plate 1 becomes a space 4 for enclosing the liquid 3.

Further, the upper plate 1 is formed with a connecting projection piece 5 at the center of each of two adjacent sides at the same time, and the connecting projection piece 5 is formed on each of the other two adjacent sides so as to correspond to the connecting projection piece 5. Form a connecting notch 6 with which the piece 5 can engage.

Further, on the lower surface of the upper plate 1, at the same time, a pair of parallel partition walls 7, 7 that are in contact with the legs 2 and extend from one side of the lower surface of the upper plate 1 to the other side are formed. Board 1
On the lower surface of the pair of partition walls 7, 7
Inside, the ends form auxiliary walls 8,8 connecting to them in a 90 ° angular relationship.

In the space 4, a flat circular tank 9 containing a liquid 3 having a volume of about ⅓ is charged, and a veneer plate 10 is attached to the upper surface of the upper plate 1. The veneer plate 10 projects from the side of the upper plate 1 by a length corresponding to half the length of the connecting projection 5 on the two adjacent sides, and recedes from the side by the same length on the other two adjacent sides. Attach it in the same condition. Thus tank 9
Is in a state of being hermetically held in the space 4.

As the liquid 3, water containing a preservative was used. A decorative plate 11 is attached to the veneer plate 10.

A polytetrafluoroethylene resin is arranged on the lower surface of the leg 2 to form a smooth surface 12.

On the other hand, a flat square lower plate 13 similar to the upper plate 1 is formed, a polytetrafluoroethylene resin is arranged on the upper surface thereof to form a smooth surface 14, and a synthetic rubber plate 15 is arranged on the rear surface.

In this embodiment, however, since it is configured as described above,
It can be used as a floor for preventing vibration by constructing a floor by arranging the floor base 16 continuously.

Of course, the floor base 16 is made smooth, and the floor members 17, 17, ... Are arranged in series on the floor base 16.

As shown in FIG. 3, first, the lower plate 13 is disposed on the floor base 16 with the smooth surface 14 facing upward, and the upper plate 1 is disposed while the legs 2 are placed thereon. Thus, the floor members 17, 17 ... Are sequentially arranged on the floor base 16.

Adjacent floor members 17, 17 are arranged such that their connecting sides are in contact with each other while the connecting projections 5 and the connecting notches 6 of each upper plate 1 are engaged with each other.

In the vicinity of the wall surface in the room, the floor members 17, 17 ... Are installed with a gap of about 15 mm between them and the cushion member is inserted into this gap.

When the floor members 17, 17 ... Are connected in series as described above, a protective passage 18 is formed between the partition walls 7, 7 between the adjacent floor members 17, 17. If necessary, wires / pipes are inserted into the protection passage 18. This protects the wiring and piping.

However, when the floor members 17, 17 ... Are installed to construct the floor as described above, when vibration such as an earthquake is applied to the floor,
First, the entire upper plate 1 tries to maintain a stationary state due to inertial force. Since the lower surfaces of the legs 2 of the upper plate 1 and the upper surface of the lower plate 13 are formed with smooth surfaces 12 and 14, respectively, the sliding surfaces 12 and 14 slide on each other, so that the lower plate 1 accompanying the vibration of the building
Despite the vibration of 3, the entire upper plate 1 tries to maintain a stationary state.

However, since the smooth surfaces 12 and 14 respectively formed on the lower surface of the leg 2 and the upper surface of the lower plate 13 cannot be perfect smooth surfaces, that is, smooth surfaces having a friction coefficient of 0, in reality, the upper plate 1 as a whole is However, the stationary state due to the inertial force cannot be maintained, and the vibration of the lower plate 13 has to generate some vibration.

When the entire upper plate 1 is vibrated in this way, the liquid 3 enclosed in the tank 9 arranged in the space 4 of the leg 2 acts to prevent the vibration, and the leg 2
Vibration of the entire upper plate 1 including is suppressed. That is, as described above, this is because the characteristic vibration frequency of the liquid 3 is lower than the frequency of vibration due to a general earthquake or the like. Conversely, this is because the liquid 3 has a unique vibration period longer than the vibration period due to a general earthquake or the like. However, the liquid 3 does not easily resonate with vibration such as an earthquake,
Even if the entire upper plate 1 starts to vibrate, it tries to maintain a stationary state, so that the liquid 3 collides with the inner wall of the tank 9 in the space 4 of the leg 2 in any stroke of the reciprocating vibration. . Needless to say, this acts as a reverse force relative to the vibration caused by the earthquake, and this suppresses the vibration of the entire upper plate 1.
Needless to say, such an action by the liquid 3 is
This can be caused by the amount of the liquid 3 which is relatively free to move and which is less than the capacity of the tank 9.

In this way, the upper plate 1 is suppressed from vibrating despite the vibration of the building including the lower plate 13. Therefore, the upper plate 1 of the floor member 17 receives almost no vibration even if a vibration such as an earthquake occurs, and can almost suppress the vibration of the floor constituted thereby.

Further, since the synthetic rubber plate 15 is arranged on the lower surface of the lower plate 13, the floor formed by the floor members 17, 17 ...

FIG. 4 shows another example of the lower plate in the floor member.

The lower plate 23 has a smooth surface 24 similar to the lower plate 13 in the upper surface.
And rubber members 25, 25 ... Of "gourd" shape having flat upper and lower ends are arranged on the lower surface. The rubber members 25 are arranged at the four corners and the center of the lower surface of the lower plate 23.

When this lower plate 23 is adopted, a sufficient vibration prevention effect against vertical vibration can be obtained. Of course, the walking feeling is also improved.

[Advantages of the Invention] If the floor member of the present invention constitutes a floor, vibration due to vibration such as an earthquake applied to a building is suppressed on the upper plate side, and a floor with extremely little vibration can be obtained.

In the event of an earthquake or other vibration, first the entire upper plate of the floor member tries to maintain a stationary state due to inertia, and at that time, a smooth surface is formed on each of the lower surface of the upper plate leg and the upper surface of the lower plate. As a result, the two slide on each other to maintain the stationary state of the entire upper plate. However, since the friction coefficients of both the above-mentioned smooth surfaces cannot be 0, the upper plate cannot be affected by the vibration of the lower plate at all, and eventually some vibration is transmitted. Then, when the upper plate starts to vibrate even a little, since the liquid less than its capacity is sealed in the space of the leg, the vibration suppressing action by the liquid works, and the entire upper plate is As a result, the started vibration can be suppressed, and the almost stationary state can be maintained. The principle of the vibration suppressing action is based on the fact that the characteristic vibration period of the liquid is longer than the period of vibration due to a general earthquake or the like. To explain this in more detail, however, liquids that do not easily resonate with vibrations such as earthquakes due to the difference in the cycle length will remain stationary even when vibrations such as earthquakes are transmitted and the upper plate begins to vibrate. Since the liquid is to be held, the liquid collides with the inner wall of the space of the leg body in both strokes of the reciprocation of the vibration, whereby the vibration of the entire upper plate is suppressed.

Therefore, in the floor constituted by the floor member of the present invention, the upper plate side is relatively free from the vibration of the floor base, and the above-described vibration suppressing action makes it possible to maintain a substantially stationary state.
