Description

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

[Prior Art] As the floor member as described above, there is basically proposed a structure in which legs are formed in the lower part of the plate material and rubbers are attached to the lower ends of these legs.

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

Therefore, it is one of the objects of the present invention to deal with this, and further, at the bottom of the floor member, a passage that can organize and guide the wiring and piping is formed, and the guide direction and the It is an object to be able to freely change the relationship between the arrangement direction of a floor material (when there is directionality) and the direction.

[Means for Solving Problems] The gist of the configuration of the present invention is that a base is provided with a passage for wiring and piping at a lower portion thereof, and a circular recess is provided at the center thereof. A holding frame having a plurality of holding means for floor plates is slidably mounted on the upper surface, and the base and the holding frame are rotatably connected at the lower end to the center of the circular recess. Further, the floor member is joined to the central portion of the holding frame by a cylindrical rubber member whose upper end is rotatably joined.

In principle, there is no reason to limit the base to a specific shape, but in consideration of handling, it is preferable to form the base into a generally square shape. Easy to mold with plastics. A suitable size is about 30 cm to 50 cm square.

It is preferable that the passages are parallel to each other on the lower side of the base, with about one passage each. The shape thereof may be an inverted U shape, an arch shape or the like.

Further, it is suitable that the circular concave portion is formed in a mortar type or a cylindrical type having a bottom. However, for the convenience of connecting the lower end of the cylindrical rubber member to the bottom portion, it is preferable to slightly raise the central portion in a circular trapezoidal shape. In addition, a coupling means corresponding to the coupling means at the lower end of the cylindrical rubber member is formed in the central portion thereof. For example, when the cylindrical rubber member is formed into a bolt as described later, a bolt hole having a corresponding dimension is formed in advance.

The upper surface of the base is preferably formed as a smooth surface so that the holding frame can be slidably mounted. On the other hand, it is appropriate that the lower surface of the holding frame is also formed as a smooth surface.

Incidentally, it is appropriate that a rubber sheet is joined to the lower surface of the base after being joined to the holding frame.

It is preferable that the holding frame is configured to have an outer shape when viewed from a plane, which is substantially the same as that of the base. That is, if the base is a flat square, the holding frame is also square. A connection male part and a connection female part are formed around the periphery of the connection male 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 floor materials formed in a rectangular shape or a square shape in plan view, for example, a plurality of floor plate materials. For example, a peripheral wall is formed around it, and a fixing base for fixing it is arranged inside according to the arrangement of the floor material. The floor material can be fixed to the fixing table with screws or the like. The means for holding the floor material is not limited to this.

A coupling means corresponding to the coupling means at the upper end of the cylindrical rubber member is formed in the center of the holding frame.
As will be described later, when it is a metal disc having a diameter larger than that diameter, it suffices to simply form a coupling hole having a diameter slightly larger than the diameter of the cylindrical rubber member.

A reinforcing plate is arranged in the lower part of the holding frame depending on the weight of the article placed on the floor member. In that case, a smooth surface will be formed on the lower surface of the reinforcing plate. For example,
A peripheral wall facing downward is formed on the peripheral edge of the holding frame, and the reinforcing plate is supported thereby.

As described above, the columnar rubber member has, as a coupling means, a metal disc having a diameter larger than the diameter thereof, for example, being adhered and fixed to the upper end thereof, and a bolt is hung from the center at the lower end thereof.
However, in this cylindrical rubber member, the upper end of the cylindrical rubber member is fixed to the holding frame by inserting it into the connecting hole from above and fixing the floor member to the holding frame by joining it. Fix it. At the lower end, the bolt is inserted into the bolt hole at the center of the circular recess of the base, and fixed with a nut. Naturally, by loosening the nut, the upper and lower holding frames and the base can be rotated relative to each other.

The material of the rubber material of the cylindrical rubber member is not limited to a particular one, but it is suitable to mold it with synthetic rubber having appropriate elasticity. It is suitable to prepare various elastic rubber members at appropriate stages and to use them properly according to the weight of the articles placed on the floor.

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

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

Next, a floor material is disposed and bonded in the holding frame. For this, adhesion by an adhesive or screwing can be freely adopted.

When the floor material is screwed from the lower part of the holding frame, it is necessary to change the procedure and join the floor material before joining the lower end of the cylindrical rubber member to the base.

Then, a rubber sheet is bonded to the lower part of the base, the bonding is fixed with an adhesive, and these floor members are arranged in a predetermined area. A slight gap is provided near the periphery of the installation area, that is, at a position adjacent to the wall surface or the like, and a cushion member is arranged in the gap.

The floor base may simply be made of concrete and made smooth.

The floor members adjacent to each other are arranged while being connected to each other by the connecting male portion and the connecting female portion formed around the holding frame. In this case, naturally, the orientation of the base is set according to the arrangement direction of the wiring and piping. At the same time or later, the wiring pipes are inserted and arranged in the wiring pipe passages of the base. If the floor material is a flat rectangle, etc., it may be necessary to orient it in a specific direction because of the pattern on the floor surface.In such a case, the base and holding frame should be circular. Since the columnar rubber members are rotatably coupled, the holding frame side may be rotated in a required direction.

When the amount of wiring pipes is large or the diameter of the pipes is large, another base can be connected under the base with the lower surfaces facing each other. In this case, the original upper surface of the lower base is placed on the base. It is the same that a rubber sheet should be bonded to this surface.

However, in the case where the floor member of the present invention is arranged on the floor substrate in this way to form the floor, the base and the holding frame are slidably joined even when vibration is transmitted to the floor substrate due to an earthquake or the like. Since they are joined by a cylindrical rubber member, the vibrations or swings can be transmitted to the holding frame side here by the sliding movements caused by the vibrations or swings. Be cut off.

In this way, the seismic isolation effect is also obtained.

The four of them arranged on one holding frame 10 correspond to the front and rear ends from the lower end to the upper end of the peripheral wall 11 for the inner two floor plate members 19b and 19b, as shown in FIG. The deleting portions 20 and 20 are formed by deleting the thickness of the peripheral wall to the position. Further, with respect to the other two floor plate members 19a, 19a, deletion portions 20, 20 are formed at the same position, and a deletion portion 21 is formed on one side portion by deleting the thickness from the lower end to the same height as the above. Form.

In this embodiment, since it is configured as described above, it can be used for constructing a floor of a building that attenuates earthquakes and other shaking as follows.

The floor members of this embodiment are prepared in advance in an amount corresponding to the floor area of the building to be installed.

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 upper end metal disk 18 contacts the bottom surface of the holding frame 10.

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 sheets arranged on both sides of the holding frame 10 have deletion portions 21, 20, 2 on one side and front and rear ends.
The floorboard members 19a and 19a having the number 0 are used, and the two center plates are floorboard members 19b and 19b having the deleted portions 20 and 20 formed at the front and rear ends. Insert the array so that it cannot be seen from above.

After that, the screws 22 are screwed from the back surface side into the screw holes 13 formed at the centers of the two holding bases 12, 12 located at both ends of each floor plate member 19a, 19a, 19b, 19b, respectively, and Each floor plate member 19a, 19a, 19b, 19b is fixed in the holding frame 10. As a result, the metal disk 18 of the columnar rubber 3 is sandwiched between the lower surfaces of the floor plate members 19b, 19b and the floor surface of the holding frame 10 and fixedly held at this position.

Then, the lower surface of the holding frame 10 is joined to the upper surface of the base 1. That is, both the smooth surfaces 9 and 17 are made to face each other. Then, the coupling bolt 5 at the lower end of the columnar rubber 3 penetrates into the bolt hole 6 of the coupling base 4 which is raised in the circular recess 2 of the base 1 as shown in FIG. From the lower surface side of the above, screw the nut 23 into the coupling bolt 5,
The lower end of the cylindrical rubber 3 is joined to the joining base 4 at the center of the base 1.

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

This is repeated to prepare the required number of floor members.

After that, they are sequentially arranged in the installation area of the building. The floor base should be concrete and smooth.

Further, a cushion member is provided around the installation area of the floor member, that is, at a position adjacent to the wall surface or the like. The floor member is in contact with the wall surface through the cushion member.

This floor member is a connection tongue piece 1 formed on the peripheral side of the holding frame 10.
The floor members 4 and the connection holes 15 connect the adjacent floor members to each other. At this time, the orientation of the base 1 is naturally set according to the arrangement direction of the wiring and piping. At the same time or later, the wiring pipes are inserted and disposed in the wiring pipe passages 7 of the base 1. In this example, the floor board member 1
Since 9a and 19b are flat rectangles, it is necessary to orient the respective directions in a specific direction due to the pattern formed on the floor surface. In this case, the base 1 and the holding frame 10 are mutually supported by the columnar rubber 3. Since they are rotatably coupled, the holding frame 10 side can be rotated in a required direction to correspond to the pattern.

However, when the floor members are arranged on the floor substrate in this way to form a floor, the base 1 and the holding frame 10 can slide relative to each other even when vibration is transmitted to the floor substrate due to an earthquake or the like. Since they are joined to each other by the columnar rubber 3, the transmission of the vibration or swing to the holding frame 10 side is interrupted by the sliding movement of each other in response to the vibration or swing. It Since the diameter of the circular recess 2 is set to be sufficiently large, the slidable range is large and it is possible to cope with large vibration.

EFFECTS OF THE INVENTION According to the present invention, when a floor is constructed, the floor member forming the floor surface is installed in the holding frame slidably connected to the base when an earthquake or other vibration occurs. Vibration is blocked by and the vibration is not transmitted. The upper holding frame is connected to the base by the central cylindrical rubber member,
Since the circular concave portion of the base can have a sufficiently large diameter, a large sliding range can be secured. Therefore, the vibration can be blocked in response to a large earthquake.

Further, it has a passage for guiding the wiring and pipes and can protect them. Moreover, since the holding frame and the base are rotatably coupled, the holding frame can be rotated according to the pattern above,
It can be turned in any direction.

In addition, the floor has a soft walking feeling.
