DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock when a person jumps on a floor of a building and a shock absorption when a car or a train such as an elevated structure passes.

[0002]

2. Description of the Related Art Conventionally, the absorption of a heavy floor impact on a double floor of a building is disclosed in Japanese Patent Application Laid-Open Nos.
As in the application of No. 160751, the mainstream is a method of attaching a floor covering material to a lower part of a bolt for height adjustment on a supporting floor, mounting a floor base material via a mounting material on an upper part, and affixing a finished floor material thereon. I have. Among them, the main part of the shock absorption is that the vibration isolating rubber is compressed and absorbs energy when a shock is applied.

However, the vibration transmissibility of the vibration isolating rubber is 10%.
The frequency efficiently absorbed is about 50 Hz or more, depending on other design conditions. On the other hand, the frequency of heavy floor impact caused by walking or jumping of a person is 20 to 100 Hz. As a result, the vibration absorption between 20 and 50 Hz is transmitted to the supporting floor without being absorbed by the vibration isolating rubber, and the lower frequency having higher energy is transmitted to the lower floor as vibration and impact sound.

As a result, in the case of a heavy concrete floor, since the vibration itself is absorbed by the concrete itself, it is possible to take countermeasures by the method as already applied, but in a lightweight wooden house, the absorption performance is low and almost no effect is obtained. Not used because there is no. On the other hand, on roads and railroads, the frequency at the time of impact cannot be specified due to the speed of cars or trains or the distance between wheels. However, anti-vibration rubber cannot absorb low frequencies, and the reduction of vibration pollution is small.

[0005]

The problem to be solved is that a widely used anti-vibration rubber cannot absorb a low frequency with a large energy at the time of a strong impact.

[0006]

Means for Solving the Problems By using a leaf spring whose both ends are moved in the lateral direction according to the magnitude of the impact load, a shock absorber is used which mainly absorbs a low frequency having a large energy. This is to reduce the impact.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The material of the shock absorber is metal or plastic. The plastic is reinforced with glass or carbon fiber as necessary.

[Claim 1] The shock absorber 1 shown in FIG.
Consists of an upper member 2 made of a leaf spring material and a lower member 3 for locking the upper member 2 to a supporting structure material. Upper member 2 is load receiving material 4
A diagonal member 5 extending downward on both sides of the diagonal member and a sliding piece 6 extending laterally outside the diagonal member 5 are integrally formed. The diagonal member 5 is provided with a hole for attaching the shock absorber 1 as necessary,
The hole 9 is also provided immediately below the.

The lower member 3 is longer than the upper member which is pressed in the event of an impact and extends in the lateral direction, and its end is bent to cover the sliding piece 6 to form a pressing member 10 as a pressing member, and the tip 11 is slidable. The moving piece 6 is pressed. In addition, locking pieces 12 for locking the diagonal members 5 of the upper member 2 at predetermined positions are provided at the lower ends of the diagonal members 5 on both sides. The pressing piece 10 may extend to the diagonal member 5 without bending the tip and press the diagonal member 5.

FIG. 1 (b) shows the movement of the sliding piece 6 and the pressing piece 10 during impact loading by a dashed line. When an impact load is applied to the load receiving member 4, as the load receiving member 4 moves downward, the diagonal member 5 pushes the sliding piece 6 sideways while relaxing the angle.
At this time, the sliding piece 6 rotates about the joint lower surface of the oblique member 5 and the sliding piece 6 as an axis, and the tip slightly lifts up, and the pressing piece 10 also moves upward.

FIG. 1 (c) shows an example in which aluminum or plastic is used for the lower member, the lower member end is extended, and the attachment piece 13 to the supporting structure is formed by extrusion.
Mounting holes for nails and the like are provided.

Things.

The shock absorber 15 shown in FIG. 1 (e) has a second spring member 19 arranged on the lower surface of the load receiving member 16 and integrally formed by a face member connecting the tops. The second spring member 19 is mounted as needed when the change width of the load is large. When the load is small, the second spring member 19 does not contact the support structure member, but a strong impact is applied and the load receiving member 16 sinks greatly. At that time, the bent piece 20 of the second spring presses the lower member 18 to reduce the amount of sinking.

The shock absorber 21 shown in FIG. 1F has a U-shaped cutout provided in a part of the load receiving member 22 and a part of the diagonal member 23, and is bent downward to form a second spring 24. . There is a gap between the tip of the second spring 22 and the lower member 26, and when a large impact is applied, the second spring 24 presses the lower member 25 to become a spring.

The shock absorber 27 shown in FIG. 1 (g) is composed of a load receiving material 28 and a diagonal material 29 when plastic is used as a material.
This method is used when high strength is required.

The holes 42 and 43 formed in the diagonal member 35 and the lower member 38 are for attaching the shock absorber 33 to the support structure by screws, but holes may be provided by extending both sides of the lower member 38.

The shock absorber 45 shown in FIG.
Is bent inward from the load receiving member 46, and the lower end portion 48 of the diagonal member is easily moved inward when a load is applied.
It is bent to reduce resistance during sliding. Further, the lower member 50 and the sliding piece 49 are provided with a portion that is slightly bent upward from the contact portion with the lower member 50 so that the tip does not contact the lower member 50 due to the rotation during the load.

When the lower end of the diagonal member 47 is bent so as to entirely contact the lower member 50, the sliding of the diagonal member 47 is suppressed, so that the spring of the upper member 46 is hardened. The pressing piece 51 for pressing the sliding piece 49 from the lower member 50 is provided with a U-shaped notch 52 at the tip end of the sliding piece 49 and bent downward to be bent.

The lower end of the diagonal member 56 and the lower member 57 are in contact with each other but are not integrated, and this portion slides when a load is applied. The tip 60 of the diagonal member 56 is rounded to eliminate the possibility of catching during sliding. Holes 58 are provided at both ends of the lower member 57 for attachment to the support structure material. When a load is applied, the diagonal member 56 is pushed to form a gentle angle, and the tip 60 moves inward. At this time, the connecting member 59 is curved because the upper member 55 has a sufficient length to be lowered.

FIG. 3B shows the lower member 57 and the diagonal member 5 when a load is applied.
6 is indicated by a chain line. Although the direction of the diagonal member 56 is directed inward in the drawing, it may be formed outward, and if the strength is insufficient, the plate may be thickened as shown in FIG. Some materials.

In addition to laying on the elevated structure 148, an anchor is provided on the back side of the shock absorber at the time of manufacturing the concrete floor slab 149 so that the shock absorber of a required length can be installed at the same time. When it is driven in, the construction becomes easy. Thereafter, pavement for roads is laid on floor slabs for roads, and rails are laid for tracks. This method can also be used for a subway or a track inside a building.

[0042]

The shock absorption of the leaf spring is effective at the frequency described in the "Prior Art", so that the effect of absorbing the low frequency generated in a building or an elevated structure is large. The feature of the shock absorber of the present invention is that the upper member has a simple chevron shape, and the end moves in accordance with the strength of the shock. Deforms according to strength.

Regarding the type of the spring, the length of each of the shock absorbers can be freely changed, so that it is easy to design according to the size, strength, and location to be used. In terms of productivity, it is also suitable for high-mix low-volume production, and can be stamped and pressed for metals and extruded for plastics, resulting in high production efficiency and low cost.

Except for the third aspect, the lower member has a box-like shape and a flat plate on both sides covering the sliding pieces. The lower member only needs to be able to cope with the friction during sliding and the vertical load. Choice is possible. Also, since the shape is bent in one direction, extrusion molding is possible with plastic and aluminum,
Since it only needs to be cut to the required length according to the upper member,
Cost can be reduced because dimensional correspondence is easy.

The shock absorber of claim 3 uses the rubber-like elastic body as a support for the sliding piece, so that the shock absorption of the rubber-like elastic body can be obtained in accordance with the shock absorption of the leaf spring. .

The shock absorber according to claim 4 is a shock absorber that can be used also when a shock object moves in a row like a car or a train, and is always located immediately below the shock object. Therefore, the bending of the support plate can be stabilized. The shock absorber of FIG. 5B has a large area for the load receiving member, and therefore can cope with a case where a plurality of mounting members are joined.

[Claim 5] When a joint member such as a joist is mounted based on a module such as a floor of a building, if the individual shock absorbers are directly mounted on the support structure, it takes time for positioning and mounting, and it takes time in the field. Productivity drops significantly. For that purpose, adjust the shock absorber to the distance between the joining members,
Since it is attached to a connection body with a good workability, the number of positioning portions is reduced and mounting is facilitated, so that productivity is improved, and the construction period and cost can be reduced.

[Claim 6] The conventional "for attaching a rubber-like elastic body or a plastic cushion material to the lower part of a bolt" used for supporting a slab or for a double floor is as described in the prior art. Low frequency cannot be absorbed, and only low performance can be obtained.

On the other hand, the present invention utilizes the fact that the leaf spring is suitable for absorbing a low frequency with a large energy, so that the impact becomes extremely small, so that a countermeasure by a conventional simple method is impossible. It is also possible to reduce the heavy floor impact sound of a wooden building. In addition, even in apartments, the performance is several steps better than before.

[Claim 7] Conventionally, rubber is used. However, since the weight of the pavement material of the road and the railway is large, the rubber is required to be large and thick, and the cost is high. Also, there are few applications because vibration and vibration attenuation cannot absorb low frequencies.

On the other hand, the present invention relates to FIG. 1, FIG. 2, FIG.
It only holds one of the shock absorbers having a simple cross-sectional shape shown in FIGS. 4 and 5, and increases the thickness of a heavy object such as a railway, or increases the length to increase the load. Can be easily handled.

Attachment of the shock absorber simply involves embedding an anchor attached to the shock absorber when producing concrete slabs. Also, since it is only laid at the site, the cost for mounting the shock absorber is unnecessary,
No time is required for installation.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock when a person jumps on a floor of a building and a shock absorption when a car or a train such as an elevated structure passes.

[0002]

2. Description of the Related Art Conventionally, the absorption of a heavy floor impact on a double floor of a building is disclosed in Japanese Patent Application Laid-Open Nos.
As in the application of No. 160751, the mainstream is a method of attaching a floor covering material to a lower part of a bolt for height adjustment on a supporting floor, mounting a floor base material via a mounting material on an upper part, and affixing a finished floor material thereon. I have. Among them, the main part of the shock absorption is that the vibration isolating rubber is compressed and absorbs energy when a shock is applied.

However, the vibration transmissibility of the vibration isolating rubber is 10%.
Approximately 15
Hz is effective at frequencies above, but the rubber
Higher frequency due to various conditions
It becomes the vibration isolation effect from the number. On the other hand, the running of children in houses
When jumping in the gymnasium, floor vibration of 15Hz or less occurs.
Therefore, vibrations that cannot be absorbed by the vibration isolating rubber are transmitted to the supporting floor,
Vibration and impact sound are heard on the lower floor.

As a result, in the case of a heavy concrete floor, since the vibration itself is absorbed by the concrete itself, it is possible to take countermeasures by the method as already applied, but in a lightweight wooden house, the absorption performance is low and almost no effect is obtained. Not used because there is no. On the other hand, on roads and railroads, the frequency at the time of impact cannot be specified due to the speed of cars or trains or the distance between wheels. However, anti-vibration rubber cannot absorb low frequencies, and the reduction of vibration pollution is small.

[0005]

The problem to be solved is that a widely used anti-vibration rubber cannot absorb a low frequency with a large energy at the time of a strong impact.

[0006]

According to the present invention, a shock absorber is used which mainly absorbs a low frequency with a large energy by using a leaf spring which slides in a lateral direction according to the magnitude of the impact load. And reduce the impact.

[0042]

According to the present invention, the shock absorption of the leaf spring is compared at the same transmission rate.
If it is more than the lower limit, it is about 15Hz than the anti-vibration rubber
Since the effect is obtained at a low frequency, the absorption effect is large at a low frequency generated in a building or an elevated structure. The feature of the shock absorber of the present invention is that the upper member has a simple chevron shape, and the end moves in accordance with the strength of the shock. Deforms according to strength.

Regarding the type of the spring, the length of each of the shock absorbers can be freely changed, so that it is easy to design according to the size, strength, and location to be used. In terms of productivity, it is also suitable for high-mix low-volume production, and can be stamped and pressed for metals and extruded for plastics, resulting in high production efficiency and low cost.

Except for the third aspect, the lower member has a box-like shape and a flat plate on both sides covering the sliding pieces. The lower member only needs to be able to cope with the friction during sliding and the vertical load. Choice is possible. Also, since the shape is bent in one direction, extrusion molding is possible with plastic and aluminum,
Since it is merely cut to the required length in accordance with the upper member, the cost can be reduced because the dimensional correspondence is easy.

The shock absorber of claim 3 uses the rubber-like elastic body as a support for the sliding piece, so that the shock absorption of the rubber-like elastic body can be obtained in accordance with the shock absorption of the leaf spring. .

The shock absorber according to claim 4 is a shock absorber that can be used also when a shock object moves in a row like a car or a train, and is always located immediately below the shock object. Therefore, the bending of the support plate can be stabilized. The shock absorber of FIG. 5B has a large area for the load receiving member, and therefore can cope with a case where a plurality of mounting members are joined.

[Claim 5] When a joint member such as a joist is mounted based on a module such as a floor of a building, if the individual shock absorbers are directly mounted on the support structure, it takes time for positioning and mounting, and it takes time in the field. Productivity drops significantly. For that purpose, adjust the shock absorber to the distance between the joining members,
Since it is attached to a connection body with a good workability, the number of positioning portions is reduced and mounting is facilitated, so that productivity is improved, and the construction period and cost can be reduced.

[Claim 6] The conventional "for attaching a rubber-like elastic body or a plastic cushion material to the lower part of a bolt" used for supporting a slab or for a double floor is as described in the prior art. Low frequency cannot be absorbed, and only low performance can be obtained.

On the other hand, the present invention utilizes the fact that the leaf spring is suitable for absorbing a low frequency with a large energy, so that the impact becomes extremely small, so that a countermeasure by a conventional simple method is impossible. It is also possible to reduce the heavy floor impact sound of a wooden building. In addition, even in apartments, the performance is several steps better than before.

[Claim 7] Conventionally, rubber is used. However, since the weight of the pavement material of the road and the railway is large, the rubber is required to be large and thick, and the cost is high. Also, there are few applications because vibration and vibration attenuation cannot absorb low frequencies.

On the other hand, the present invention relates to FIG. 1, FIG. 2, FIG.
It only holds one of the shock absorbers having a simple cross-sectional shape shown in FIGS. 4 and 5, and increases the thickness of a heavy object such as a railway, or increases the length to increase the load. Can be easily handled.

Attachment of the shock absorber simply involves embedding an anchor attached to the shock absorber when producing concrete slabs. Also, since it is only laid at the site, the cost for mounting the shock absorber is unnecessary,
No time is required for installation.
