Description

  The present invention relates to a disaster prevention apparatus for a house that can absorb seismic energy and suppress shaking and lifting of the house.

In recent years, in view of human damage and economic loss associated with earthquakes, an excellent seismic isolation structure has been required for personal houses as well as large-scale high-rise buildings (see Patent Document 1). As this seismic isolation structure for a house, although not shown, for example, a structure in which a slider and a rubber composite layer are arranged side by side between a ground and a structure of a house is known (see Patent Document 2).
Japanese Patent Laid-Open No. 10-184096 Japanese Patent Laid-Open No. 2003-213961

  The conventional seismic isolation structure for a house has a slider and a rubber composite layer arranged between the ground and the structure of the house as described above. There is a problem that the construction becomes very large. In addition, due to the complexity of the structure, the purchase price of a house becomes extremely expensive. This is a big obstacle for individuals to purchase, regardless of whether a corporation with a large amount of funds purchases. There is not much fear of inviting.

  On the other hand, conventional seismic isolation structures are generally built on the premise of large-scale high-rise buildings, so wind pressure (the force by which the wind shakes the building) is greater than the seismic force (the force by which an earthquake shakes the building). There is a problem in applying it to wooden homes that have a large impact. In other words, if the seismic isolation structure is easily applied to a small-scale house, a structure that tends to sway becomes a trap, and a big problem arises that the house sways even in a wind that does not sway in a non-base-isolated house. In particular, in the case of strong winds, typhoons, etc., there is a high possibility that the house will continue to shake and cause anxiety and discomfort to the residents.

And a second receiving tray 12 which is opposed to the first receiving tray 11 positioned below with a gap, and a flexible elastic body that connects between the first and second receiving trays 11 and 12. 17 and an earthquake which is accommodated in the elastic body 17 and contacts the opposing surfaces of the first and second saucers 11 and 12 and moves in all directions when an earthquake occurs and acts on the base 2 from the foundation 1 of the house. And a sphere 18 for suppressing energy.

  In a house, a base 2 made of wooden squares is mounted on a base 1 having a rectangular cross section placed by concrete, and a large draw or joist (not shown) is supported on the base 2. A plurality of round through holes 4 for anchor bolts 3 are drilled in the base 2 at intervals by a drill or the like before or during construction work.

  As shown in FIG. 1 and FIG. 2, the first and second receiving trays 11 and 12 are formed into a flat rectangular plate using a material such as steel. A plurality of through holes and nuts 13 are provided and face each other in the vertical direction. A flat rectangular plate-shaped spacer 14 made of hard rubber or the like is interposed between the foundation 1 of the house and the first tray 11 and between the base 2 of the house and the second tray 12.

  A moving area 15 for the sphere 18 is formed in a plane circular shape on the opposing surfaces (front surfaces) of the first and second trays 11 and 12, and a positioning hole for the sphere 18 is formed at the center of the moving area 15. 16 are each formed into a shallow circular small recess in a planar circle. The opposing surfaces and the moving region 15 in the first and second trays 11 and 12 may be flat, but are inclined or curved so that the central portion is low and other peripheral portions are high from the viewpoint of positioning the sphere 18. May be.

  The elastic body 17 is formed into a flat rectangular block using chloroprene rubber, ethylene-propylene rubber, acrylonitrile-butadiene rubber, etc. that are excellent in mechanical properties and elasticity, have little heat generated by vibration, and have excellent resistance to aging. At the center, a hollow cylindrical portion is formed that communicates with the moving region 15 and loosely accommodates the sphere 18, and the damping and restoration are integrally performed to greatly increase the response displacement of the seismic isolation device 10. It functions to prevent the sphere 18 from rusting as well as to prevent it from becoming too much.

  The elastic body 17 can be formed of a single rubber, but can also be formed by alternately laminating seismic isolation rubber with through holes and thin reinforcing plates in the vertical direction. In this case, the material of the seismic isolation rubber includes polyurethane rubber, natural rubber, silicone rubber, and the like, and the material of the reinforcing plate includes various resins, metals, SUS, and the like.

  The sphere 18 is made of, for example, a single iron ball or steel ball having a diameter of 60 to 80 mm, or 75 to 80 mm, and is slidably contacted with the opposing surfaces of the first and second trays 11 and 12 so as to allow rolling contact. When the earthquake occurs, the seismic energy is absorbed and the first and second trays 11 and 12 are moved and displaced. The number of the spheres 18 is appropriately increased or decreased in consideration of costs and the like.

  As shown in FIGS. 4 to 10, each shaking prevention device 30 is mounted and supported so as to be slidable on the support 31 attached to the lower surface of the base 31 of the house and the base 31 of the house. And a lock mechanism 41 that locks the storage body 35 to the receiver 31, and is configured to operate in response to the occurrence or end of an earthquake. The receiving tool 31 and the storage body 35 are comprised, for example using various steel materials, and are installed in the basic | foundation area | region of the house which can be maintained from the outside by the maintenance staff.

  The receiving tool 31 is formed in a flat rectangular shape, and a pair of bolt holes 32 are perforated at intervals, and the anchor bolts 3 integrated with the foundation 1 are screwed into the bolt holes 32 from above. (See FIGS. 4 and 5). A receiving hole 33 positioned between the pair of bolt holes 32 is formed in a substantially track shape on the surface of the receiving tool 31, and a plurality of iron balls 34 having low frictional resistance are provided in the receiving hole 33 in the front, rear, left, and right directions. It is directly arranged to be movable in all directions. The plurality of iron balls 34 slidably mount and support the storage body 35, support the load of the house, and function to smoothly shake the house.

  The storage body 35 includes a box frame 37 having a substantially inverted U shape in section and screwed to the lower surface of the base 2 via a pair of fasteners 36 such as a pair of mounting bolts, and a box frame 37 having openings at both ends. A bottom plate 38 that is in contact with and supported by the plurality of iron balls 34 is horizontally installed under the side walls 37 (see FIGS. 6 to 8). As shown in FIGS. 6 and 7, the box frame 37 is formed longer than the support 31, and an inspection port 39 for the lock mechanism 41 is drilled in a horizontally long rectangle on the side wall. The horizontally long lid 40 is detachably screwed from the outside through a plurality of screws.

  As shown in FIGS. 6, 7, and 10, the lock mechanism 41 includes a pair of notches 42 formed at both ends of the receiver 31, a hydraulic damper 43 built in the storage body 35, and the hydraulic pressure A pump 46 that supplies oil to the damper 43 from the tank 44 via a pipe, a flow control valve, a check valve, a relief valve 45, and the like, a motor 47 that operates the pump 46, and a storage body 35 are rotatably supported. The hydraulic damper 43 includes a pair of lock claws 48 fitted and locked to the notch 42 of the receiving member 31 when the hydraulic damper 43 is driven.

  Each notch 42 is notched in a substantially reverse groove shape in cross section on the lower surface of the longitudinal end portion of the receiving tool 31, and a convex portion 49 that engages with the lock claw 48 is formed in the longitudinal direction on the inner upper surface. The hydraulic damper 43 includes a pair of pistons 50 that can be moved back and forth in the horizontal direction, and is installed horizontally in the box frame 37 of the storage body 35 via a fixture, and if necessary, the inspection port 39 of the box frame 37. It is operated from.

  The pump 46 and the motor 47 are integrated or provided separately, and are installed inside and outside the house as necessary. As the pump 46, for example, a small, light and inexpensive gear pump or vane pump is used. Further, the motor 47 is formed of, for example, a stepping motor, a servo motor, an AD servo motor, a DC servo motor, or the like, and it is preferable that the operation panel can be operated from inside the house.

  The pair of lock claws 48 are pivotally supported in the vicinity of both ends of the box frame 37 of the storage body 35 via pins so as to be rotatable in the vertical direction, and are rotatably connected to the tip of the piston 50 of the hydraulic damper 43 via the pins. The Each lock claw 48 is formed in a horizontal L shape, and its width (left and right direction in FIG. 8) is shorter than the width of the notch 42 (left and right direction in FIG. 9). The projection 49 is fitted and locked via an error absorbing clearance 51.

  In the above configuration, when an earthquake occurs and the foundation 1 of the house vibrates, the sphere 18 of the seismic isolation device 10 rolls within the elastic body 17 to exert a bearing function, and the first and second saucers 11 and 12 are respectively It slides in the opposite direction and receives the shaking of the earthquake, and the house will be seismically isolated by this effect (see FIG. 2). Due to such a seismic isolation action, the furniture of the house does not fall, and the resident does not feel fear.

  During these operations, the anchor bolt 3 and the elastic body 17 that extend vertically in the vertical direction suppress the floating of the base 2, the sphere 18 supports the load of the house, and the flexible elastic body 17 softly shears and deforms. Absorbs and absorbs the rolling applied to the house.

  On the other hand, when wind is blown by a strong wind or typhoon and is affected by wind pressure, an operation switch on an operation panel (not shown) of the shaking prevention device 30 may be operated after checking with a weather forecast. Then, the motor 47 is driven to operate the hydraulic pump 46, and oil (for example, wear-resistant hydraulic oil, phosphate ester hydraulic oil, etc.) is supplied from the tank 44 to the hydraulic damper 43, and the piston of the hydraulic damper 43. 50 projects.

  When each piston 50 of the hydraulic damper 43 protrudes, each lock claw 48 swings downward and is firmly fitted and locked to the notch 42 of the receiving tool 31 via the convex portion 49. By this fitting and locking, The foundation 2 of the building is locked to the foundation 1 and has the same configuration as that of the non-base-isolated house (see FIG. 7).

  When winds such as strong winds and typhoons stop and are no longer affected by wind pressure, the operation switch on the operation panel can be operated in reverse to prepare for the occurrence of an earthquake. Then, the motor 47 is driven to operate the hydraulic pump 46, the oil is discharged from the hydraulic damper 43 to the tank 44, and the piston 50 of the hydraulic damper 43 returns to the original position. When each piston 50 of the hydraulic damper 43 retreats, each lock claw 48 swings upward and disengages from the notch 42 of the receiving tool 31. By releasing this fitting lock, the receiving tool 31 and the storage body 35 are moved. It becomes relatively slidable, and the base 2 is unlocked to the foundation 1 to form a base-isolated house (see FIG. 6).

  When an earthquake occurs in this seismic isolation structure, the plurality of iron balls 34 rolls in the receiving hole 33 to exert a bearing function, and the receiving tool 31 and the receiving body 35 slide relative to each other in the longitudinal direction. Due to the shaking of the earthquake, this effect causes the house to shake slowly. Due to this seismic isolation action, the furniture does not fall, and the resident does not feel a sense of fear.

  According to the above, since it is not necessary to use the base 2 that supports the house as a steel frame, the construction can be facilitated, simplified, and facilitated. Further, since the structure is relatively simple, the purchase price of the house does not become extremely expensive. Therefore, it does not become a big obstacle when an individual purchases a house, and does not cause a dwindling desire to buy a house. Moreover, since the spacer 14 which fills a clearance gap is interposed between the foundation 1 of the house and the first tray 11 and between the base 2 and the second tray 12 of the house, respectively, the installation of the disaster suppression device is actually performed. It becomes easy.

  In addition, since the positioning holes 16 are formed in the first and second trays 11 and 12, respectively, and the movement of the sphere 18 in the front-rear and left-right directions is restricted, the sphere 18 rolls down during installation and assembly of the disaster suppression device. There is no hindrance to work. Moreover, since the spherical body 18 supports the longitudinal load, the elastic body 17 can be prevented from being compressed more than necessary, and the attenuation of the seismic energy can be greatly expected.

  In addition, when affected by wind pressure, the base 2 can be locked to the foundation 1 to make a structure similar to that of a non-base-isolated house. There is almost no floating. Therefore, even if the wind continues to be blown by strong winds or the like, there is no possibility that the house will continue to shake and cause anxiety or discomfort to the residents. In addition, in the event of an earthquake, the base 2 can be unlocked to make a base-isolated house, so that the house can be rocked slowly to absorb the seismic energy.

  In addition, if the lid 40 is removed and the inspection port 39 of the box frame 37 is opened, the hydraulic damper 43 can be seen and touched, so that maintenance and inspection work can be significantly smoothed, simplified and facilitated. Can be planned. Further, the width of the notch 42 is wider than the width of the lock claw 48, and a clearance 51 for error absorption is secured between the notch 42 and the lock claw 48. Even if it shifts in the width direction relatively due to an earthquake or the like, the storage body 35 can be reliably locked to the support 31.

  Furthermore, since the notches 42 and the convex portions 49 form irregularities that are easily caught, it is possible to greatly improve the degree of locking of the distal end portions of the lock claws 48. Furthermore, since the shake prevention device 30 of the present embodiment has a relatively small number of parts and a simple configuration, it can be manufactured at a low cost (for example, 400,000 yen or less), resulting in a significant increase in housing costs. There is no.

  Next, FIGS. 11 and 12 show a second embodiment of the present invention. In this case, a switch 52 that links the seismic isolation device 10 and the shake prevention device 30 to the foundation 1 of a house is supported. In other words, a plurality of ring-shaped attenuation grooves 19 are notched at intervals from the center of the opposing surfaces of the first and second receiving trays 11 and 12 to the peripheral portion in the seismic isolation device 10, in other words, radially outward. The elastic body 17 is formed into a cylindrical shape opened in the vertical direction.

  The switch 52 is formed, for example, in a pin shape extending in the vertical direction, and is supported on the foundation 1 of the house so as to be movable up and down via a return spring 53, and from the positioning hole 16 of the first tray 11 to the elastic body 17. Protrusively penetrates inside. Such a switch 52 is pressed down by the sphere 18 when an earthquake does not occur, and locks the storage body 35 to the receiving member 31 by the check valve of the shake prevention device 30. When the earthquake occurs, the switch 52 is connected to the moving sphere 18. The check valve is released based on the separation and functions to release the lock claw 48 of the storage body 35 that has been fitted and locked from the recess of the receiver 31.

  The opposing surface of the first tray 11 is formed such that the central portion including the positioning hole 16 is low and the peripheral portion of the moving region 15 is high, and functions to restrict excessive movement of the sphere 18. A plurality of ribs 20 extending endlessly in the circumferential direction are integrated with the peripheral wall of the elastic body 17, and each rib 20 is formed in a circular cross section.

  In the above configuration, when the sphere 18 that has been fitted in the positioning hole 16 due to an earthquake rolls in the elastic body 17 and the sphere 18 and the switch 52 are separated to raise the switch 52, the check valve of the hydraulic circuit is raised. Is released, and each lock claw 48 is removed from the notch 42 of the receiver 31, and the release of this engagement locking makes a structure of a seismic isolation house in which the receiver 31 and the storage body 35 can slide relative to each other. .

  Thereafter, when the earthquake stops and the sphere 18 is fitted back into the positioning hole 16, the sphere 18 and the switch 52 come into contact with each other and the switch 52 is lowered. When the switch 52 is lowered, each locking claw 48 swings and engages and locks with the notch 42 of the receiver 31, and the receiver 31 and the storage body 35 are locked by this engagement and locking, so It becomes the structure of a seismic house. The other parts are substantially the same as those in the above embodiment, and thus description thereof is omitted.

Also in this embodiment, the same effect as the above embodiment can be expected, and the seismic isolation device 10 and the shake prevention device 30 are interlocked, so that the operation panel and the like can be omitted to simplify the configuration. It is clear. Further, since a plurality of endless attenuation grooves 19 are arranged in parallel on the opposing surfaces of the first and second trays 11 and 12, excessive movement of the sphere 18 can be effectively restricted. Furthermore, since the peripheral wall of the elastic body 17 is not a mere plate shape in a longitudinal sectional view, but is formed in a concavo-convex shape, it is possible to expect a significant improvement in attenuation and restoration.
Note that when the interlocking between the seismic isolation device 10 and the shake prevention device 30 is not particularly required, the switch 52 may be omitted as shown in FIG.

  Next, FIGS. 14 to 16 show a third embodiment of the present invention. In this case, the elastic body 17 of the seismic isolation device 10 is formed into a cylindrical shape opened in the vertical direction. A plurality of ribs 20 extending in the vertical direction are integrated with the peripheral wall 17 and each rib 20 is bulged and formed into a circular cross section.

  The plurality of ribs 20 are arranged side by side in the circumferential wall circumferential direction of the elastic body 17 with a predetermined interval. As shown in FIG. 14, each rib 20 is formed in a waveform pattern that is continuous in the vertical direction, but is not limited to this. For example, the linear portion and the ring portion are alternately continuous. A pattern extending in the vertical direction (see FIG. 16A), a pattern in which the linear portions and the hollow rhombus portions alternately extend in the vertical direction (see FIG. 16B), or a linear portion and a chevron Can be formed in a pattern (see FIG. 16C) extending alternately and continuously in the vertical direction. The other parts are substantially the same as those in the above embodiment, and thus description thereof is omitted.

  In this embodiment, the same effect as the above embodiment can be expected, and the ribs 20 swelled in the radial direction are integrally formed on the peripheral wall of the elastic body 17 to improve the strength. It is clear that in addition to the remarkable improvement of the above, diversification of the shape of the peripheral wall and improvement of the strength can be expected.

  In the present embodiment, the elastic body 17 is formed into a cylindrical shape with a single rubber, but the present invention is not limited to this. For example, as shown in FIG. 17 and FIG. 18, the curved vertically long rubber pieces 21 are arranged in the circumferential direction at intervals, and the elastic body 17 is formed in a substantially cylindrical shape opened in the vertical direction. It is also possible to integrate the ribs 20 extending in the vertical direction and form each rib 20 into a circular cross section.

Next, FIGS. 19 and 20 show a fourth embodiment of the present invention. In this case, the elastic body 17 of the seismic isolation device 10 is formed into a cylindrical shape, and the tensile strength is formed on the peripheral wall thereof. The mesh body 22 which is excellent in the shape is insert-molded.
The elastic body 17 is formed into a cylindrical shape by insert molding in which a mesh body 22 made of a wire mesh or the like is inserted into a laminated soft rubber or a flexible elastomer, for example. The other parts are substantially the same as those in the above embodiment, and thus description thereof is omitted.

  In this embodiment, the same effect as the above embodiment can be expected, and the elastic body 17 is not simply used, but the mesh body 22 having excellent tensile strength is inserted into the elastic body 17, so It is obvious that damage and breakage of the elastic body 17 accompanying the above can be effectively suppressed with a simple configuration.

Next, FIGS. 21 to 24 show a fifth embodiment of the present invention. In this case, a frustoconical holding tool 23 is suspended on the opposing surface of the second tray 12 and the tip thereof is shown. A small sphere 18 slidably contacting only the facing surface of the first tray 11 is rotatably supported on the part.
A chamfer is formed between the surface of the first tray 11 and the peripheral edge from the viewpoint of preventing cracks and cracks. The holder 23 is formed in a substantially conical shape upside down using a hard metal or the like, and its tip is formed in a hollow shape, and the hard sphere 18 is partially exposed in this hollow tip. Thus, it is fitted and held so as to roll freely.

  In the above configuration, when an earthquake occurs and the foundation 1 of the house vibrates, the holder 23 with the sphere 18 moves as a slider through the hollow portion of the elastic body 17 to exert a bearing function, and the first and second saucers 11 and 12 slide in opposite directions and receive the shaking of the earthquake. The other parts are substantially the same as those in the above embodiment, and thus description thereof is omitted.

  Also in the present embodiment, substantially the same effect as the above-described embodiment can be expected, and since the holder 23 supports the longitudinal load, it is possible to effectively prevent the elastic body 17 from being compressed more than necessary. It is obvious.

Next, FIGS. 25 to 28 show a sixth embodiment of the present invention. In this case, the hydraulic damper 43 of the lock mechanism 41 is provided with one piston 50 capable of moving forward and backward in the horizontal direction. A square type is used, and the square type is increased in a pair on the left and right sides and arranged in a row in the storage body 35. The other parts are substantially the same as those in the above embodiment, and thus description thereof is omitted.
In this embodiment, the same effect as the above embodiment can be expected, and the configuration of the lock mechanism 41 can be diversified.
