Description

Detailed Description of the Invention [Field of Industrial Application] The present invention is used in various buildings to protect various types of equipment that should be protected from various vibrations or swings caused by earthquakes or various types of mechanical equipment. This relates to flooring materials that should be used in the room where it is installed.

[Prior Art] A seismic isolation floor member has been proposed in which a plurality of legs are suspended from the lower surface of a floor board and an i-resistant material is attached to the lower ends of the legs.

[Problems to be Solved by the Invention] Although it is possible to obtain a slight seismic isolation effect with the above-mentioned floor member, since only elastic material is attached to the lower surface of the legs, the effect is not very high, and the structure It cannot be said that it is highly practical. Furthermore, the seismic isolation effect against horizontal vibrations is not sufficient.

[Means for Solving the Problems] The gist of the present invention is as follows: A plurality of legs each having a smooth lower end and an elastic body for regulating a sliding range are configured to hang down from the bottom surface of a substrate, while Separately, a bottom plate with a smooth upper surface to be laid on the subfloor is constructed, the lower ends of the legs of the base plate are slidably joined face-to-face on the bottom plate, and the lower ends of the elastic bodies are fixedly fixed. This is a floor member configured to obtain.

The substrate can be made of any material such as wood, plastics, or metals. Plastics have good moldability and are easy to use. The substrate is formed into a generally square planar shape. Its size may be determined depending on handling convenience, and is suitably about 30 cm square to 50 cm square.

Appropriate decoration can be applied to the upper surface of the substrate as required. For example, a vinyl sheet or a plastic sheet may be attached, or a wooden board may be attached. A sheet or panel made of an appropriate material may be attached to match the interior, or other suitable decoration may be applied.

1. The legs should be arranged hanging down from the bottom surface of the board in a well-balanced manner. For example, it is appropriate to form a structure that hangs down from the four corners and the center of the lower surface of the substrate. The shape of the lower part of the leg body can be freely configured into a cylinder or a prism, but it is preferable to configure the lower end to be a circular surface. Also"
1. A plastic film with a low coefficient of friction is formed on the lower surface of the leg to provide an appropriate smooth surface. Any suitable conventional technique may be employed. In some cases, an elastic piece having a smooth lower surface may be attached to the lower end of the leg. By doing so, it is possible to prevent some vibration in the vertical direction, and to improve the walking feeling when walking on it.

Furthermore, since it is preferable to use the space between these legs as a passage for wiring or piping, appropriate consideration should be taken to protect these.

The elastic body is suitably a rubber cylinder made of a rubber material with good elasticity.

Similar to the substrate, the bottom plate can be made of wood, plastic, metal, or the like, which can be freely selected.

Unlike a board, it is more convenient for construction to construct it as a large-sized plate.

The upper surface of the floor plate is made into an appropriate smooth surface by forming a film of plastic having a low coefficient of friction, etc., in the same way as the smooth surface constructed on the lower surface of the leg. Naturally, any suitable conventional technique can be employed.

The second gist of the present invention is that a plurality of legs having smooth lower ends are formed to hang down from the lower surface of the base plate, and on the other hand, a plurality of pedestals whose upper ends are smooth are formed on the upper surface of the bottom plate. The board is configured to protrude in a positional relationship corresponding to the base plate, the base plate is made to face the base plate, the lower end of the latter leg is slidably joined face-to-face to the upper end of the former pedestal, and the upper surface of the former and the latter This is a floor member whose lower surface is connected with a plurality of elastic bodies for regulating the sliding range.

This is the same as - of the present invention except for the structure of the bottom plate.

The base plate can be configured in exactly the same manner as the base plate, except for whether or not the decorative plate is provided. Of course, in this case, the substrate is turned upside down and used as a bottom plate.

Similarly, the elastic body is preferably a rubber cylinder made of a rubber material with good elasticity. In this case, the present invention is the same except that it is slightly longer than -.

In addition, as in the case of - of the present invention, it is also possible to attach an elastic piece with a smooth lower surface to the lower end of the leg body, or attach an elastic piece with a smooth upper surface to the upper end of the pedestal. The present invention-
It is preferable for the same purpose.

[Function] Therefore, the second and second floor members of the present invention are used as follows.

First, the present invention will be explained in detail.

First, a floor plate is laid on the subfloor inside the building. By laying down an appropriate number of sheets, the entire subfloor surface is covered with the floorboards. The floorboards are fixed to the subfloor l- with adhesive or the like.

Next, substrates are sequentially placed on the base plate. In the vicinity of the surrounding wall in the room, leave a gap that slightly exceeds the maximum amplitude in an earthquake, etc. up to the surrounding wall. At this time, the lower ends of the elastic bodies hanging down from each board are fixed to the two sides of the bottom plate. It is also appropriate to use an adhesive or the like for this purpose. In this way, the substrate is placed except for the above-mentioned gap, and the lower end of the elastic body is connected and fixed to the bottom plate at the corresponding position.

Insert a suitable cushioning member into the above gap.

Note that when installing the floor member in this manner, telephone wires, electric wires, scrap piping, etc. are sequentially inserted into the spaces created between the legs of the board, as necessary.

According to the floor constructed from the above-described floor members, a seismic isolation effect can be obtained in the following manner.

When vibrations or shaking occur, such as an earthquake, the floorboards naturally vibrate or shake along with the subfloor. However, the base plate is simply connected to the floor plate at the lower ends of the legs, and both the lower ends of the legs and the upper surface of the base plate are formed into smooth surfaces. Therefore, the maximum frictional force that can be transmitted between the lower ends of the legs and the upper ends of the bottom plate is small, and even slight vibrations easily cause slipping, and vibrations transmitted to the bottom plate are no longer transmitted to the base plate. Therefore, the board remains static regardless of the vibrations of the bottom plate, etc.
1 = can maintain a state or a state close to rest.

Note that when the amplitude increases in an earthquake or the like, the bottom plate vibrates greatly, and the relative amplitude of the substrate to the bottom plate becomes sharper. However, since the sliding range is restricted by the elastic body connecting the base plate and the bottom plate, the relative vibration does not become large enough to cause an extreme change in the positional relationship.

Therefore, a floor made of this floor member is advantageous because vibrations or rocking motions are not easily transmitted even in the event of an earthquake or the like. It is particularly suitable as a floor for rooms where equipment that is sensitive to vibrations is installed.

The second aspect of the present invention will be explained below.

When the second floor member of the present invention is to be installed on the subfloor inside a building, a necessary number of floor members are first prepared.

As described above, in this floor member, the base plate faces the base plate, the lower end of the leg body of the latter is slidably joined to the upper end of the pedestal of the former, and the -L surface of the former and the lower surface of the latter are elastically connected. Connect and compose with your body.

Prepare a number of these according to the size of the room in which they are to be installed, as shown in "-", and install them one by one on the subfloor of the room with the bottom plate facing downward. It is appropriate that the floorboard be attached to the floor substrate -1- with an adhesive or the like. At this time, a gap slightly larger than the maximum amplitude in an earthquake, etc. should be left between the room and the surrounding wall in the vicinity of the room. In this way, the floor members are installed on the entire sub-floor surface except for the gap shown in the figure.

Insert a suitable cushioning member into the above gap and complete the floor installation.

When installing the floor components in this way, as necessary, telephone lines, electric wires, gas piping, etc. should be sequentially inserted into the space created between the legs of the board and the base of the floor plate in 1. That's it.

According to the floor constituted by the above-mentioned floor members, a seismic isolation effect can be obtained based on the same principle as described in - of the present invention.

That is, in the event of an earthquake, the lower ends of the legs and the upper ends of the pedestal easily slip due to slight vibrations, and vibrations transmitted to the bottom plate are no longer transmitted to the base plate. In this way, the substrate can maintain a stationary state or a nearly stationary state regardless of vibrations of the bottom plate or the like.

In addition, even if the floor plate vibrates significantly during an earthquake, the sliding range of the board is restricted by the elastic body connected between the base plate and the base plate, so it may not be possible to cause extreme changes in the positional relationship. The relative vibration does not become large.
