Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floor in which a large number of them are continuously arranged on a floor substrate, and various cosmetic materials are thereafter or previously arranged on the floor substrate to form a floor. The present invention relates to a base isolation floor member, which is a kind of member and is capable of damping vibrations and oscillations such as earthquakes.

[Prior Art] Conventional seismic isolation means basically support the floor,
It is proposed that legs are formed at the bottom of the plate and rubbers are attached to the lower ends of these legs.

[Problems to be Solved by the Invention] In the conventional seismic isolation means, as described above, rubbers are simply attached to the lower ends of the legs that support the plate material, and thus the floor by this structure is structurally satisfactory. It cannot obtain the seismic effect.

The present invention relates to a floor member for constructing a floor of a building by laying or sticking a decorative plate on the upper surface thereof, which has a high seismic isolation function with respect to horizontal and vertical vibrations or rocking. The purpose is to provide.

[Means for Solving the Problem] The gist of the configuration of the present invention is that a tapered recess having a larger diameter toward the upper side is formed in the center of a base member, and radiation is made from the upper peripheral edge of the tapered recess. A slide flange portion extending in the direction, a substrate member is slidably placed on the upper surface of the slide flange portion of the base member, and the base member and the substrate member are placed at the lower end of the tapered recess of the base member. To the base member, the upper end of the elastic member is joined to the base member by an elastic member, and the bottom of the tapered recess is joined to the lower end of the elastic member. The lower end of the elastic member is centered on the floor center. It is a seismic isolation floor member that is configured so that it can freely move only within the range of the restriction circular hole, and that a plurality of elastic legs are disposed below the base member.

It is preferable to determine the diameter and the opening angle of the bottom of the tapered recess in consideration of how much the horizontal width of earthquake in earthquakes can be tolerated. If possible, if the upper and lower ends of the elastic member make a relatively horizontal oscillating motion in the largest expected earthquake,
It is preferable to set the side portion of the elastic member so that it does not easily contact the inner circumference of the tapered recess.

Further, it is appropriate that the base member is constituted by reinforcing a plurality of ribs extending in the radial direction from the outer periphery of the conical protrusion which bulges to the lower side which is the back side of the tapered recess. Naturally, the upper portions of the plurality of ribs are integrally connected to the lower surface of the slide collar portion.

Further, it is appropriate that the slide collar portion is formed in an annular shape when seen from a plane.

The above-mentioned substrate member is suitable for that because a decorative material of the same size is attached to the upper surface of the substrate member or a decorative material is laid on the upper surface after the seismic isolation floor member is installed. For example,
It can be made of plastic or wood board. It is appropriate that the plane shape is a square shape when viewed from a plane for the purpose of use.

The slidable joint between the slide collar and the substrate member can be ensured by a free structure. For example,
This can be realized by forming each joint surface as a smooth surface by coating the surface with a tetrafluoroethylene resin or the like. Alternatively, a plurality of balls may be rotatably disposed on either the upper surface of the slide collar or the lower surface of the substrate member, and the other facing surface may be joined to the plurality of balls.

The elastic member may be formed of a material having an appropriate elasticity into an appropriate shape. For example, it is a rod-shaped or columnar member provided with appropriate coupling means at the upper end and the lower end. More preferably, the columnar elastic body is formed at a position corresponding to the diameter of the ring-shaped elastic body, and appropriate connecting means is formed at positions corresponding to both ends of the columnar elastic body, as in the above example. Both sides of the ring-shaped elastic body are preferably made slightly thinner. Still another example is a member having a configuration in which the columnar elastic body is removed from the above member.

It is suitable to use chloroprene-based synthetic rubber or the like as the material of each elastic body.

At the bottom of the tapered concave portion, for example, a regulation circular hole provided with an inwardly protruding retaining collar is provided at the upper edge, and on the other hand, as a connecting means for the lower end of the elastic member, it is necessary to have a diameter larger than the diameter of the regulation circular hole. By attaching a coupling disc configured to have a smaller diameter, insert the coupling disc into the regulation circular hole from the back surface of the tapered recess, and lock the lower end of the elastic member by locking the retaining collar. It is movably connected only in the restriction circular hole.

For example, when the ribs are formed on the back surface of the base member as described above, the elastic legs are provided with mounting holes between the ribs so as to hold the elastic legs made of an appropriate elastic material. Charge.

[Operation] Since the present invention is configured as described above, in various buildings, by arranging a plurality of it continuously on the floor base, and after that or by arranging a decorative material on the upper surface in advance, The floor can be easily constructed, and the floor can dampen vibrations or rocking transmitted to the floor base such as an earthquake.

This seismic isolation floor member forms a flat floor base in the required area, and arranges them continuously on the floor base, and by attaching or laying a decorative material on or in advance on the floor base, construction can be done easily. A floor of things can be constructed.

It should be noted that a slight gap is provided at the outer edge of the installation area of the seismic isolation floor member, that is, a position adjacent to the wall surface or the like, and, for example, a cushion member is arranged in the gap. Alternatively, it is appropriate to dispose an auxiliary plate body that can move forward and backward in the vicinity of the outer edge of the base plate member of the base isolation floor member and the decorative material at the lower portion thereof at the above-mentioned position in the event of an earthquake or the like.

Therefore, the seismic isolation floor member of the present invention can very easily form a seismic isolation floor at a required position.

Further, in the case where the floor is constituted by the seismic isolation floor member as described above, even when the vibration is transmitted to the floor base due to an earthquake or the like, the seismic isolation can be performed very effectively.

Even in the case of a comparatively small earthquake, when the horizontal shaking is the main shaking, the lower end of the elastic member moves the bottom of the tapered recess of the base member relative to each other within the restriction of the circular hole. , It can move freely in the horizontal direction,
Correspondingly to this, the substrate member slides relatively freely on the slide collar portion, so that the seismic isolation effect can be almost completely obtained. Further, when the swing becomes larger than this and the lower end of the elastic member comes into contact with the peripheral edge of the regulation circular hole due to its horizontal movement, the lower end of the elastic member is aligned with the peripheral edge of the regulation circular hole. Engagement and relative swinging of the substrate member beyond the sliding flange portion can be performed within the elastic stretchability and range of the elastic member.

In this way, when the swing is small, the lower end of the elastic member can freely move in the horizontal direction in the regulation circular hole, so that the free slide movement on the slide collar portion of the substrate member is not regulated and the swing is prevented. In the case of large movement, when the lower end of the elastic member tries to move beyond the regulation range, the free sliding movement on the slide brim portion of the substrate member is within the range of elasticity and elasticity of the elastic member. It can be done. In any case, however, a sufficient seismic isolation effect can be obtained.

If the substrate member and the slide brim member are provided with, for example, the various effective sliding means described above, the seismic isolation effect is very effectively performed.

Further, with respect to vertical vibrations, the seismic isolation is secured by the elastic elastic expansion and contraction action of the elastic legs arranged below the base member. In addition, these elastic legs also contribute to improve the feeling of walking on the floor.

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

As shown in FIGS. 1 and 3, a restriction circular hole 6 is bored in the bottom of the tapered concave portion 2, and a retaining collar 7 extends inward from the upper edge of the inner circumference thereof.

Further, on the lower side of the base member 1, a first protrusion is formed around the conical protrusion that protrudes due to the configuration of the tapered recess 2.
As shown in FIG. 3 and FIG. 3, ribs 8a, 8a ..., 8 extending radially to the peripheral edge of the slide collar 3 at an angle of 45 °
b, 8b ... The above-mentioned ribs 8a, 8a ... Are integrally formed by two ribs, and the ribs 8b, 8b ... Are constituted by only one rib. Both of them are suspended from the lower surface of the slide collar 3, and the lower end thereof is at the same height as the lower edge of the peripheral edge of the restriction circular hole 6 formed on the lower surface of the conical protrusion. Further, leg supporting portions 9 are provided at the tips of the ribs 8a, 8a, ..., And roughly gourd type elastic legs 10 are inserted and held in these supporting holes.

Further, the substrate member 11 is slidably mounted on the upper surface of the slide flange portion 3 of the base member 1 through the large number of balls 5, 5 ,. The substrate member 11 is a square plate material when viewed from above, has a female screw 12 formed in the center thereof, and a circular concave portion formed around the lower surface thereof.

The base member 1 and the substrate member 11 are connected by the elastic member 13.

As shown in FIG. 1, the elastic member 13 includes a ring-shaped elastic body 14 and a column-shaped elastic body 15 disposed therein.
A lower coupling disc 16 is fixedly installed at a position corresponding to one end of the above, and a male screw is provided at the center of the upper surface at a position corresponding to the other end of the columnar elastic body 15.
An upper coupling disk 18 on which 17 is erected is fixed. The lower coupling disc 16 has a diameter smaller than that of the regulation circular hole 6 and larger than the inner diameter of the retaining collar 7. Further, the upper coupling disc 18 has a smaller diameter than the inner diameter of the retaining collar 7. The outer diameter of the ring-shaped elastic body 14 is also smaller than the inner diameter of the retaining pull-out collar 7.

Then, the elastic member 13 is inserted from the inside of the retaining collar 7 of the base member 1 with the upper part thereof facing upward, and the lower coupling disc 16 at the lower end is locked to the retaining collar 7. Further, the male screw 17 of the upper coupling disc 18 is attached to the female onion 12 of the substrate member 11.
Screw it on.

In this way, the base member 1 and the substrate member 11 are joined by the elastic member 13.

The ring-shaped elastic body 14, the column-shaped elastic body 15 and the elastic leg 10 are molded from chloroprene synthetic rubber. Further, in this example, the decorative material 19 is previously formed on the upper surface of the substrate member 11.
Shall be attached and placed.

In this embodiment, since it is configured as described above, it is useful to configure the floors of various buildings as those for damping earthquakes and other shaking. Moreover, its installation is easy.

First, as in a general case, a flat floor base 20 is formed in a target area forming a floor.

This seismic isolation floor member is a floor base constructed as above.
It should be arranged in line with 20. That is, with the lower surface side of the base member 1 facing downward, adjacent seismic isolation floor members may be laid on the floor base 20 with the sides of the substrate member 11 abutting each other.
The work is completed by laying in all target areas in this way.

Note that a slight gap is left at the outer edge of the installation area of the seismic isolation floor member, that is, a position adjacent to the wall surface, etc., and at that position, at the time of an earthquake or the like, at the bottom thereof, the substrate member 11 and the decorative material 19 are An auxiliary plate that can move forward and backward near the outer edge will be placed.

However, the seismic isolation floor member of this embodiment can be installed in a required position extremely easily to form a floor.

Further, in the case where the floor is constituted by the seismic isolation floor member in this manner, the seismic isolation can be performed very efficiently even when the vibration is transmitted to the floor base 20 due to an earthquake or the like.

Even in the case of a comparatively small earthquake, when the horizontal shaking is the main shaking component, the lower coupling disk 16 of the elastic member 13 has the restriction circular hole 6 formed at the bottom of the tapered upper recess 2. Within the regulation of (1), it is possible to relatively move freely in the horizontal direction, and in response to this, the substrate member 11 relatively slides on the slide collar portion 3, so that the seismic isolation is almost complete. The effect can be obtained. Also, when the swing becomes larger than this and the lower coupling disc 16 of the elastic member 13 comes into contact with the peripheral edge of the regulation circular hole 6 due to its horizontal movement. The lower coupling disc 16 is coupled to the peripheral edge of the regulation circular hole 6, and relative swing on the slide collar 3 of the substrate member 11 beyond this limits the elastic expansion and contraction of the elastic member 13. It can be done within a range.

In this way, when the swing is small, the lower coupling disk 16 of the elastic member 13 can freely move in the horizontal direction in the restriction circular hole 6, so that the slide flange 3 of the substrate member 11 can be freely slid. When the lower coupling disc 16 of the elastic member 13 exceeds the regulation range when the regulation does not occur and the swing is large, the free sliding movement of the substrate member 11 on the slide flange portion 3 is prevented. This means that an effective seismic isolation action can be performed within the range of elasticity and elasticity of the elastic member 13.

Since the two rows of annular holes 4 and 4 are formed on the slide collar 3 and the balls 5, 5, ... Are rotatably arranged in the respective holes,
The board member 11 placed on this can slide extremely smoothly, and the seismic isolation effect is very effectively performed.

With respect to the vibration in the above-mentioned direction, the seismic isolation is ensured by the elastic expansion and contraction of the elastic legs 10, 10 ... Arranged at the bottom of the base member 1 in the axial direction.

[Effect of the Invention] According to the present invention, when an earthquake or other vibration occurs, the vibration or swing transmitted to the floor base is largely blocked, and the members above the base member have extremely small vibrations or more. I tried not to let things be transmitted.
