Abstract

(57) [Summary] [Problem] If vibrations such as earthquakes are transmitted directly from the foundation to the base, the impact cannot be reduced. In addition, vibrations coming from railways and roads on which large vehicles and the like run degrade buildings. SOLUTION: An anti-vibration sheet 1 having seismic isolation and having projections 10 on both upper and lower surfaces is laid on a foundation 6 along an anchor bolt 2 which is provided from the foundation 6, and an anchor bolt insertion hole is provided thereon. 15 and the anchor 5
Then, the washer 3 is attached to the anchor bolt 2 and tightened with the nut 4 to lightly fix the vibration-proof sheet 1 by pressure bonding.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention relates to damping of vibration transmitted from a building foundation to a foundation.

[0002]

[Prior art]

  Conventionally, the damping and seismic isolation of buildings, etc. were designed assuming a large earthquake. The method and laminated rubber bearings are equipped with various dampers. Also insulation There are methods, but they are both large and expensive. In the sheet form for the purpose of vibration isolation , Noboru No. 2583472.

[0003]

[Problems to be solved by the device]

  Of the above, the laminated rubber bearing method is suitable for high-rise buildings, and is generally used for wooden construction and lightweight. Steel structures are too expensive and unrealistic. The above mentioned Noboru No. 2583472 is flat A flat plate with surface protrusions on both sides is stacked on the bottom plate to form a unit, and the upper and lower plates are pierced. Although it is a base protection plate with embedded wires, it requires a small number of manufacturing processes It also reacts to small shakes. With the present invention, it is easy to adjust when building for the purpose. The goal is to be inexpensive, easy to use, easy to manufacture, and cost effective. .

[0004]   Also, just putting the damping sheet on the foundation will cause repeated vibrations within many years. Misalignment occurs.

[0005]

[Means for Solving the Problems]

  In order to achieve the above object, the vibration damping sheet of the present invention, which is inserted between the foundation and the foundation. Is a vibration-damping sheet with vibration-damping sheets that have protrusions on both upper and lower sides. Base lined with anchor bolts and anchor bolt insertion holes Insert the washer into the anchor bolt and lay it, then attach the washer to the anchor bolt and It is configured to damp vibrations by tightening with is there.

[0006]   And because of repeated vibrations for many years, wooden It is desirable to attach a pointed pin or the like to the protrusion on the base.

[0007]   In addition, a groove for fitting the damping sheet is provided on the bottom side of the foundation, so that the foundation and the damping sheet are It is also preferable to embody.

[0008]

[Embodiment of device]

  An embodiment of the invention will be described with reference to the drawings on the basis of examples, as shown in FIG. In an embodiment of the present invention, there is a vibration-isolating property, for example, both made of ethylene propylene rubber or the like. Anchor bolts in which the vibration-damping sheet 1 having the protrusions 10 on the surface is upright from the foundation 6 and is continuous. The base 5 with the anchor bolt insertion holes 15 extending therethrough. Install the washer 3 on the anchor bolt 2 after inserting and laying it in the anchor bolt 2. It is fixed by tightening lightly with a cap 4.

[0009]   FIG. 2 shows a part of the shape of the protrusion 10. Both are vibration-proof sea The projections 10 are formed on both sides of the gutter. (A) is a square with a flat surface (b) Is cylindrical, but the surface may be flat or spherical (c) is a spherical protrusion. shape The shape is not limited and may be a diamond shape or the like.

[0010]   FIG. 3A is a perspective view in which the same part as in FIG. It shows a state in which the pointed pin 20 is embedded. (A) is a pin It is sectional drawing which inserted 20 between the foundation 6 and the base 5. The pointed pin 20 is used for wooden construction Used as a base.

[0011]   FIG. 4 (A) shows a concave groove and a concave portion in the lower part of the base 5 with a U-shape facing downward. 25, and the damping sheet 1 is projected from the base 5 to the foundation 6 side by several millimeters. It has been fitted. If necessary, it may be glued with an adhesive to form a complete unit. Yes. The damping sheet 1 shown in the figure is a flat plate using a vibration-isolating rubber. (A) is (A) It is a II-II sectional view of a figure.

[0012]   FIG. 5 (B) shows the case in which the vibration damping sheet 1 having the protrusion 10 is inserted, and the other parts are shown in FIG. And the structure is the same. Use the protrusion 10 with protrusions on both sides as shown in FIG. You may. FIG. 3B is a sectional view taken along line III-III in FIG.

[0013]   As shown in FIGS. 4 and 5 above, the vertical cross-sectional view of FIG. The damping sheet 1 is fitted into the recessed part 25 and the base and sheet are integrated into The anchor bolt 2 is inserted into the anchor bolt hole 15 provided in the base 5 and the foundation 6 is placed. The washer 3 is mounted and the nut 4 is tightened and fixed.

[0014]

[Effect of device]

  Since the present invention is configured as described above, it will be described below. Has a great effect.

[0015]   With the structure according to claim 1, the vibration from the foundation is projected on both upper and lower surfaces. In order to be absorbed by the vibration damping sheet and attenuated and transmitted to the base, The impact is weakened.

[0016]   Also, since there are protrusions on both sides, the upper base side has good air flow and is naturally ventilated. Since it is dry and dry, it prevents the base from corroding, and because it is not damp, it is difficult to breed even termites. It also becomes an ant. In addition, in the case of a decorative foundation where the lower part is exposed, rainwater will be However, due to the gap, rainwater evaporates in a short time and does not collect moisture.

[0017]   According to claim 2, in the case of a wooden house, the pointed pin at the center of the protrusion of the vibration damping sheet is It may get stuck in the base due to its own weight and may be displaced due to vibration over many years. There is no.

[0018]   Even if the damping sheet is inserted into the base of claim 3, the base and the sheet are not integrated. The position does not change because of In addition, this method does not locate even on steel frames unlike pointed pins It can be used for prevention. In addition, the length of the damping sheet that projects from the bottom of the foundation to the foundation side The width of the vibration transmitted from the foundation can be adjusted accordingly.
