Japanese Patent Laid-Open No. 10-184096 Japanese Patent Laid-Open No. 2003-213961

  Conventional seismic structures for private houses have sliders and rubber composite layers arranged between the ground and the structure of the private house as described above, but this requires a large number of parts and makes the structure very complicated. There is a problem of doing. Moreover, since the purchase price of a house becomes remarkably expensive, it becomes a big problem in the case of an individual purchase, regardless of the purchase of a corporation with a large amount of funds, and there is a possibility that the desire to purchase a house is reduced.

  The present invention has been made in view of the above, and an object of the present invention is to provide an inexpensive earthquake-resistant pad for personal housing that can simplify the structure.

In the present invention, in order to solve the above-mentioned problem, it is provided in a private house and absorbs seismic energy,
Including a pair of seismic mats interposed between the foundation of the private house and the base, and an elastic seismic body provided between the pair of seismic mats,
Mounting protrusions are provided on the exposed surface of each seismic mat, and the elastic seismic body is composed of a plurality of seismic rubbers arranged side by side between the top and bottom of a pair of seismic mats, and a reinforcing plate attached to each seismic rubber It is characterized by that.

In addition, the through groove | channel for bolts which connects the foundation and foundation of a private house can be notched in the edge part of an earthquake-resistant mat and an elastic earthquake-resistant body.
Further, the mounting groove can be cut out in the circumferential direction on the peripheral surface of the protrusion.

  Here, the basis in the claims includes an independent basis and a solid basis. On the contact surface of the seismic mat that comes into contact with the base, a plurality of grooves that perform aeration and drainage functions can be appropriately formed in the vertical direction, the horizontal direction, or the vertical and horizontal directions. Further, the elastic seismic body may be covered with a covering rubber so as to suppress a decrease in adhesion performance between the seismic rubber and the reinforcing plate.

  The protrusion is formed into a columnar shape, a prismatic shape, a polygonal columnar shape, or the like using a predetermined elastomer, metal, or the like, and is integrated with the seismic mat or configured as a separate body. The protrusions can be a plurality of protrusions such as 6, 8, 10, etc., and R can be appropriately provided between the protrusion and the earthquake-resistant mat. The bolt includes at least various anchor bolts that are foundation bolts. Furthermore, the mounting groove can be formed on the peripheral surface of each protrusion, or can be formed on the peripheral surface of any protrusion.

  According to the present invention, when the foundation of a private house is shaken and the foundation and the base are displaced in the horizontal direction, the bolt suppresses the floating of the base, and a plurality of elastic earthquake-resistant bodies sandwiched between a pair of earthquake-resistant mats are configured. The seismic rubber deforms while being controlled by the reinforcing plate in the lateral direction, and attenuates or absorbs the shaking applied to the private house.

  According to the present invention, there is an effect that it is possible to provide an inexpensive earthquake-resistant pad for private housing that can simplify the structure.

  Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, an earthquake-resistant pad for a private house in the present embodiment includes a foundation 1 and a base 2 of a private house. It is provided with a pair of upper and lower seismic mats 10 that are in close contact with each other and an elastic seismic body 20 that is interposed between the opposing seismic mats 10. The seismic energy acting on the private house is cut off and absorbed.

  Individual houses (also referred to as independent houses, detached houses, and detached houses) are fixed on a foundation 1 with a rectangular cross-section placed by concrete with multiple anchor bolts (bolts) and nuts (not shown). Is done. The base 2 is made of wooden square material, and a large drawing or joist (not shown) is supported on the upper surface. Further, the anchor bolts are selectively fitted with seismic isolation cylinders (not shown), and function to suppress and prevent the vertical movement of the private house during an earthquake.

  A pair of seismic mats 10 are spaced apart in the vertical direction, and each seismic mat 10 is molded to the same size as the foundation 1 and the base 2 using a predetermined rubber or metal, and has a wide contact area. Secure. Each seismic mat 10 is formed into a planar rectangle using, for example, natural rubber, chloroprene rubber, ethylene-propylene rubber, acrylonitrile-butadiene rubber, etc., which are excellent in aging resistance and oil resistance. The through-holes 11 for anchor bolts oriented in the direction are each cut out into a planar rectangle.

  A plurality of hard rubbers 12 for mounting (a total of four on each surface in the present embodiment) are provided on the front surface or the rear surface, which is the exposed surface of the earthquake-resistant mat 10, at intervals in the longitudinal direction. A plurality of hard rubbers 12 are fitted into the uncured foundation 1 or base 2.

  The hard rubber 12 is formed into a cylindrical shape oriented in the vertical direction, and an endless mounting groove 13 is notched in the circumferential direction on the peripheral surface, and the mounting groove 13 is filled with uncured concrete. Thus, it is firmly connected and fixed. The hard rubber 12 is formed longer, shorter, or increased or decreased in number according to the size, strength, fixing degree, etc. of the private house (for example, four or more on each surface).

  The elastic seismic body 20 is composed of a plurality of seismic rubbers 21 that are stacked between the top and bottom of the pair of seismic mats 10, and a thin reinforcing plate 22 that is attached to each of the plurality of seismic rubbers 21 arranged in the vertical direction. A through-hole 23 for anchor bolts oriented in the vertical direction is cut out in a flat rectangular shape at the center of the short ends, and has a horizontal deformation capability.

  The plurality of earthquake-resistant rubbers 21 and the reinforcing plates 22 are alternately stacked in the vertical direction while being oriented in the horizontal direction. Each seismic rubber 21 is formed into a flat rectangular thin plate using, for example, natural rubber or silicone rubber having excellent elasticity and mechanical properties, and is passed through for anchor bolts oriented in the vertical direction at the center of the short ends. Each of the grooves 23 is cut into a planar rectangle.

  Each reinforcing plate 22 is formed in the same size as the earthquake-resistant rubber 21 using a predetermined resin material, metal plate, steel plate, rust resistant SUS, etc., and for anchor bolts oriented in the vertical direction at the center of the short ends. Each of the through-grooves 23 is cut into a flat rectangular shape, and functions to secure a large rigidity (spring constant) in the vertical direction by restricting the lateral movement of the bonded seismic rubber 21.

  In the above configuration, when installing an earthquake-resistant pad, first, a plurality of earthquake-resistant pads are arranged in a row at intervals in the longitudinal direction of the uncured foundation 1, and the foundation 1 is cured and buried therein. If the rubber 12 is integrated, the hard rubber 12 exposed in each seismic pad and the hole drilled in the base 2 are fitted, and then the foundation 1 and the base 2 are connected and fixed by a plurality of anchor bolts. Can install earthquake-resistant pad.

  When an earthquake occurs and the foundation 1 vibrates after the completion of the private house, each anchor bolt suppresses the lifting of the base 2, and the earthquake-resistant rubber 21 of the elastic seismic body 20 supports the load of the private house and softly shears. It effectively attenuates and absorbs the rolling applied to the private house.

  According to the above configuration, the slider and the rubber composite layer having different configurations are arranged side by side, or a plurality of elastic cylindrical bodies are integrally arranged at intervals between the pair of upper and lower seismic mats 10, Since it is only necessary to arrange the seismic pads having the same simple structure, the structure can be remarkably simplified. In addition, it can reduce the cost of millions of conventional earthquake-resistant costs to 800,000 yen or less, and 500,000 yen or less depending on the conditions. A seismic structure can be realized.

  In addition, since the plurality of seismic rubbers 21 and the reinforcing plate 22 are laminated, the vertical rigidity is large, a large load can be supported, and the soft rigidity and large deformation characteristic of rubber are obtained in the horizontal direction. be able to. Further, since the through grooves 11 and 23 communicating with each other ensure the insertion of the anchor bolt, the earthquake-resistant pad does not become an obstacle to the work, and the building work can be facilitated and facilitated.

  Furthermore, since the uncured concrete is filled in the mounting groove 13 in which the hard rubber 12 is recessed without any gaps, it is possible to greatly expect a strong fixation of the seismic pad while preventing displacement. Furthermore, since the mounting groove 13 is notched on the peripheral surface of all the hard rubber 12 and the seismic pad does not have a specific direction, even if the seismic pad is turned upside down, it can be easily installed without any problems. It becomes possible.

  Next, FIG. 4 shows a second embodiment of the present invention. In this case, through holes 11 and 23 for anchor bolts are provided at the center of both ends of each earthquake-resistant mat 10 and elastic earthquake-resistant body 20. Each is cut out into a semi-circular plane. The other parts are the same as those in the above embodiment, and the description thereof is omitted.

  In the present embodiment, it is obvious that the same effects as those of the above embodiment can be expected, and the shapes of the through grooves 11 and 23 can be diversified.
