Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to a floor to be used in various buildings, mainly in rooms equipped with various types of equipment to be protected against earthquakes and other vibrations. It is related to members.

[Prior Art] As the above-mentioned floor member, basically, a structure has been proposed in which legs are formed at the bottom of a board and rubber is attached to the lower ends of these legs.

[Problems to be Solved by the Invention] The conventional floor members as described above cannot sufficiently cope with horizontal shaking.

Therefore, it is one of the problems of the present invention to deal with this problem.Furthermore, in addition to configuring a passage in the lower part of the floor member that can organize and guide wiring and piping, the guide direction and the upper surface of the floor member The object of the present invention is to make it possible to freely change the directional relationship with the installation direction of the flooring material (if there is directionality).

[Means for Solving Problem 1] The gist of the configuration of the present invention is that the base is configured with a passage for wiring and piping at its lower part, and a circular recessed portion in the center. A holding frame having holding means for holding a plurality of floor planks on the upper surface side is slidably placed thereon, and the base and the holding frame are connected to each other in the circle Ha.
The floor member is connected by a cylindrical rubber member whose lower end is rotatably connected to the center of the recess and whose upper end is rotatably connected to the center of the holding frame.

In principle, there is no reason to limit the base to a specific shape, but considering convenience in handling, it is preferable to configure the base to have an approximately square planar shape. It is easy to mold from plastics. Its dimensions are 30cm square ~ 50cff
Approximately 1 square is appropriate.

The passages are preferably arranged parallel to each other on both sides of the lower part of the base. Its shape can be suitably an inverted U-shape or an arch shape.

Further, it is appropriate that the circular recess is formed into a mortar shape with a bottom, a cylindrical shape, or the like. However, in order to connect the bottom end of the cylindrical rubber member, it is preferable that the center part of the bottom part is slightly raised in the shape of a circular trapezoid. A connecting means corresponding to the connecting means at the lower end of the cylindrical rubber member is configured in the center thereof (for example, a cylindrical rubber member is configured as a bolt at the upper end, which will be described later). If so, bolt holes of corresponding dimensions shall be drilled.

Further, the upper surface of the base is preferably formed into a smooth surface so that the holding frame can be slidably placed thereon. On the other hand, it is suitable that the lower surface of the holding frame is likewise constructed to be a smooth surface.

Note that it is appropriate to bond a rubber sheet to the lower surface of the base after it is connected to the holding frame.

It is preferable that the holding frame has an outer shape that is substantially the same as the base when viewed from above. That is, if the base is square in plan, the holding frame is also square. A connecting male part and a connecting female part are formed around the connecting part, so that adjacent parts can be connected to each other. Its composition is free.

Further, the holding frame is configured to be able to hold several pieces of floor material each having a rectangular or square shape when viewed from above, such as a floor board. For example, a peripheral wall is constructed around the floor material, and a fixing base for fixing the floor material in accordance with the arrangement of the floor materials is arranged inside. The floor material can be fixed to the fixing base using screws or the like. The means for holding the floor material is not limited to this.

A connecting means corresponding to the connecting means at the upper end of the cylindrical rubber member is provided in the center of the holding frame.

As will be described later, if it is a metal disc with a diameter larger than that, it is sufficient to simply drill a coupling hole with a diameter slightly larger than the diameter of the cylindrical rubber member.

Note that a reinforcing plate may be provided at the bottom of the holding frame depending on the weight of the article placed on the floor member. In that case, a smooth surface will be provided on the lower surface of the reinforcing plate. for example,
A downward peripheral wall is formed on the peripheral edge of the holding frame to support the reinforcing plate.

As described above, the cylindrical rubber member has, for example, a metal disc having a diameter larger than that of the cylindrical rubber member adhesively fixed to its upper end as a coupling means, and a bolt is suspended from the center of its lower end. However, the cylindrical rubber member of the lever is inserted into the holding frame from above into its coupling hole, and then the floor material is bonded and fixed to the holding frame, so that the upper end of the cylindrical rubber member is fixed. Fix it. At the lower end, the bolt is inserted into the bolt hole in the center of the circular recess of the base, and tightened and fixed with a nut. Naturally, by loosening the nuts, the holding frame and the base, which are located above and below, can be rotated relative to each other.

Note that the material of the rubber material of the cylindrical rubber member is not limited to a specific one, but it is appropriate to mold it from synthetic rubber having appropriate elasticity. It is appropriate to prepare rubber members of various elasticities in appropriate stages and use them depending on the weight of the articles to be placed on the floor.

[Function] Since the present invention is configured as described above, it can be used as a floor of a building to attenuate earthquakes and other shaking as follows.

First, the holding frame is joined to the top surface of the base. The upper end of the cylindrical rubber member is coupled to the center of the holding frame by mutual coupling means, and the lower end is similarly coupled to the center of the circular recess of the base by mutual coupling means.

Next, the floor material is arranged and coupled within the holding frame.

For this purpose, adhesive bonding, screw fixing, etc. can be freely adopted.

If the floor material is screwed from the lower part of the holding frame, the procedure must be changed and the floor material must be joined before the lower end of the cylindrical rubber member is joined to the base.

After this, a rubber sheet is bonded to the lower part of the base, the bond is fixed with an adhesive, and these floor members are arranged in a predetermined area. A slight gap is left near the periphery of the installation area, that is, at a position adjacent to a wall surface, etc., and the cushion member is disposed in the gap.

The subfloor may simply be made of smooth concrete.

Adjacent floor members are disposed while being connected to each other by a connecting male part and a connecting female part formed around the holding frame. In this case, the direction of the base is naturally set in accordance with the direction in which the wiring and piping are arranged. At the same time or later, wiring and piping are inserted and arranged in the wiring and piping passages of the base. If the floor material is rectangular in plan, it will be necessary to orient it in a specific direction due to the pattern on the floor surface. It is rotatably connected by a columnar rubber member.

All you have to do is rotate the holding frame side in the required direction.

Note that when there is a large amount of wiring and piping, or when the diameter of the piping is large, another base can be used by connecting it below the base with its lower surface facing each other. In this case, it will be placed on the base with the original top surface of the lower base facing down. The rubber sheet should be bonded to this surface in the same manner.

However, when a floor is constructed by arranging the floor members of the present invention on the floor subfloor in this way, the base and the holding frame can be slidably connected even when vibrations are transmitted to the subfloor due to an earthquake or the like. Since they are connected to each other by a cylindrical rubber member, by sliding each other in response to vibrations or rocking, the transmission of those vibrations or rocking to the holding frame is cut off. be done.

In this way, a seismic isolation effect can also be obtained.

[Example] The present invention will be described in detail below based on the drawings.

As shown in FIGS. 1, 2, and 6, the base 1 is made of plastic and has a square shape when viewed from above. A circular recess 2 is formed in the center thereof, and a connecting base 4 to which the lower end of the cylindrical rubber 3 (described later) is joined is set up in the center thereof, and a connecting bolt 4 is attached to the connecting base 4, and a connecting bolt is attached to the lower end of the cylindrical rubber 3 at the center. A bolt hole 6 is bored through the hole 5. The circular recess 2 has an inner diameter that is sufficiently wide, that is, about three times the diameter of the cylindrical rubber 3.

At the bottom of the base 1, as shown in FIGS. 2 and 6, passages 7.7 are provided on both sides for passing inverted U-shaped wiring and piping in parallel to each other. Configure. It is assumed that a rubber sheet 8 is prepared on the underside of the base 1 to be bonded when the base 1 is installed on the flooring. This rubber sheet 8 has a square planar shape, and its dimensions are made to match the planar dimensions of the base 1.

Further, two surfaces of the base 1 are coated with tetrafluoroethylene to form a smooth surface 9.

On the other hand, as shown in FIGS. 3 to 6, the holding frame 10 is configured to have a square shape when viewed from above. The vertical and horizontal dimensions are each 6II
It is about 1 m thicker than the base 1 (constituted).A peripheral wall 11 is erected around the periphery, and inside, circular holding stands 12, 12, etc. are erected at equal intervals in four rows vertically and horizontally, Each in the center -
Two screw holes 13 are drilled. Further, around the holding frame 10, a connecting tongue piece 14 and a connecting hole 15 are formed on each side.

They are placed near one end and near the other end of each side, respectively. Further, the positions of the connection hole 15 and the connection tongue piece 14 in the height direction are determined from the bottom surface of the holding frame 10 to the holding base 12, 12,
... between the top surfaces.

A coupling hole 16 having a diameter slightly larger than the outer diameter of the cylindrical rubber 3 is bored in the center of the holding frame 10 .

Further, the lower surface of the holding frame 10 is coated with tetrafluoroethylene to form a smooth surface 17.

Further, as shown in FIG. 6, the cylindrical rubber 3 is molded from chloroprene-based synthetic rubber, and a metal disc 18 of a larger diameter is adhesively fixed to the upper end thereof, and furthermore, the cylindrical rubber 3 is fixed to the lower end. The connecting bolt 5 is allowed to hang down. This connecting bolt 5 has a metal disk connected to its upper end, and this metal disk is connected to the lower end of the cylindrical rubber 3, so that the connecting bolt 5 hangs down.

By the way, in this embodiment, as shown in FIG.
is held in the holding frame 10. This floor board member 1
9a and 19b have a thickness set to be approximately twice the height between the upper end of the peripheral wall 11 of the holding frame IO and the upper end of the holding table 12,
- Of the four pieces arranged in the holding frame 10, the front and rear ends of the two floor plate members 19b and 19b correspond to the upper end of the peripheral wall 11 from the lower end, as shown in FIG. A deleted portion 20.20 is formed by removing the thickness of the peripheral wall up to the position. In addition, for the other two floorboard members 19a and 19a, removed portions 20 and 20 are formed at the same position, and a removed portion 21 is formed on one side of the floor by the same thickness as above from the lower end to the same height as above. Form.

Since this embodiment is constructed as described above, it can be used to construct a floor of a building that attenuates earthquakes and other shaking as described below.

The number of floor members of this embodiment corresponding to the floor area of the building to be installed is prepared in advance.

First, the upper end of the cylindrical rubber 3 is engaged with the coupling hole 16 formed in the center of the holding frame 10. This engagement is performed by inserting the lower end side of the cylindrical rubber 3 into the coupling hole 16 from the upper side of the holding frame 10, and pulling it down until the metal circle 1'1N18 at the upper end contacts the bottom surface of the holding frame 1o. .

Next, as shown in FIG. 6, the four rectangular parallelepiped floor plate members 19a, 19a, 19b, 19b, . . . are arranged in parallel on the holding frame 10. The two pieces placed on both sides of the holding frame 10 have removed portions 21 and 20 on one side and the front and rear ends.
．． Using floor plate members 19a, ], 9a with cutout parts 20. Insert and arrange so that the upper end is hidden so that it cannot be seen from above.

Thereafter, screw the screws 22 from the back side into the screw holes 13 drilled in the center of the two holding stands 12.12 located at both ends of each floor plate member 19a, 19a, 19b, 19b. Each floor plate member 19a, 19a, 19b, 19b is fixed in the holding frame 10. As a result, the cylindrical rubber 3
The metal disc 18 is sandwiched between the lower surfaces of the floor plate members 19b, 19b and the floor surface of the holding frame 10, and is fixedly held in this position.

After this, the lower surface of the holding frame 10 is joined to the upper surface of the base l. That is, both smooth surfaces 9.17 are made to face each other. Then, as shown in FIG. 6, the connecting bolt 5 at the lower end of the cylindrical rubber 3 is in a state of penetrating the bolt hole 6 of the connecting table 4 raised in the circular recess 2 of the base 1, and Screw the nut 23 onto the coupling bolt 5 from the bottom side of the
The lower end of the cylindrical rubber 3 is connected to the connecting table 4 at the center of the base 1.

Then, a rubber sheet 8 is further bonded to the lower surface of the base 1 using an adhesive.

Repeat this to prepare the required number of floor members.

After that, they are sequentially arranged in the installation area of the building. The subfloor shall be made of concrete and smooth.

Furthermore, a cushion member is provided around the installation area of the floor member, that is, at a position adjacent to a wall surface or the like. The floor member is brought into contact with the wall surface via the cushion member.

This floor member includes a connecting tongue piece 1 constructed on the circumferential side of the holding frame 10.
4 and connection holes 15, adjacent floor members are connected to each other. At this time, the direction of the base l is naturally set in accordance with the direction in which the wiring and piping are arranged. At the same time or later, wiring and piping are inserted and arranged in the wiring and piping passages 7.7 of the base l. In this example, floor plate member 1
Since 9a and 19b are rectangular planes, it is necessary to orient them in specific directions due to the pattern formed on the floor surface. Since they are rotatably connected, the holding frame 10 side can be rotated in the required direction to match the pattern.

However, when a floor is constructed by arranging these floor members on the floor subfloor in this way, the base 1 and the holding frame 10 can slide freely relative to each other even when vibrations are transmitted to the subfloor due to an earthquake or the like. Since they are connected to each other by the cylindrical rubber 3, the two slide in response to the vibration or rocking, thereby blocking the vibration or rocking from being transmitted to the holding frame lO side. Ru. Since the diameter of the circular recess 2 is sufficiently large, the slideable range is large and it can cope with large vibrations.

[Effects of the Invention] If the floor is configured according to the present invention, in the event of an earthquake or other vibration, the floor member forming the floor surface is installed on a holding frame that is slidably connected to the base, This blocks vibrations and prevents them from being transmitted. The upper holding frame is connected to the base by a cylindrical rubber member in the center.
Since the diameter of the circular concave portion of the base can be made sufficiently large, it is possible to extend the sliding range. This makes it possible to block vibrations in the event of a large earthquake.

Furthermore, it has a passage for guiding wiring and piping, so that these can be protected. Moreover, since the holding frame and the base are rotatably connected, the holding frame can be rotated in accordance with the pattern above.
It can be turned in any suitable direction.

Also, the floor feels soft when walking on it.
