Description

  The present invention relates to seismic isolation, and particularly relates to a base for a seismic isolation layer and a seismic isolation device.

For conventional seismic isolation structures for light-weight buildings such as wooden houses (structure parts to be seismically isolated), the steel frame (steel frame) that supports the seismic isolation structure is used as the base isolation structure body and seismic isolation support. It was necessary to install between seismic isolation devices. The base of the seismic isolation layer was conventionally a steel frame base (steel base).

The price of the steel frame (steel frame) used in the conventional base frame (base isolation frame) is significantly increased. By using a wooden frame, the cost can be reduced, but there are problems such as strength and bonding. There was a need to solve it.
In particular, in a wooden mount, the joining of wooden members is generally performed by bolt joining using a joint metal or the like. In this case, a bolt is provided on the side of the member (a horizontal penetrating through the member in the horizontal (horizontal) direction). A through bolt is provided), and the transmission of stress between the members is performed by shearing the lateral through bolt. In the case of shear bolt joining in a wooden member, since the bolt is sunk into the wood, there is a problem that sufficient shear strength cannot be obtained with this transverse through shear bolt as compared with bolt joining between steel frames.
In addition, hardware (upper support material) such as iron plates necessary for joining to the seismic isolation device is exposed on the top of the wooden frame, and nailing the wooden frame such as floor plywood and lower frame material in the frame construction method Became an obstacle.
In addition, a steel frame (steel frame) can be reduced in cost if it can cope with various planes and is standardized. The same applies to the wooden frame, and the problem of the joints in both the steel frame and the wooden frame was the bottleneck for standardization.
Also, in the case of unit construction methods such as unit houses, a method of directly attaching a seismic isolation device that does not require a seismic isolation frame to the unit itself was required to reduce costs. However, there is a problem in the method of joining the seismic isolation device and the unit (unit lower steel foundation) for connecting a plurality of units to make the units stable.

  This invention is an invention that solves problems such as strength and joining caused by using a wooden frame as the frame base for the base isolation layer that supports the base isolation structure. In the steel frame (steel frame), the invention can deal with various planes and can be standardized.

The invention described in claims 1 to 4 is an invention relating to the structure of the base of the seismic isolation layer.
It is an invention that solves problems such as strength and joining required for a base of a base isolation layer by using a wooden base and a steel base (steel base) together.

  According to the first aspect of the present invention, in the base of the seismic isolation layer, there is a restoring material such as a laminated rubber and a spring, a damping material such as a damper, a wind sway fixing device, or the like which is a portion where the stress is large (compared to other portions). By constructing a steel frame (steel frame) C as the part to be installed and a wooden frame D as the rest, the cost can be reduced.

The invention according to claim 2 is the contents of claim 1, in the case of the “centrally controlled seismic isolation system”, a restoring material such as a laminated rubber / spring or the like, which is a portion where the stress is large (compared to other portions) Damping materials such as dampers or wind sway fixing devices are located in the center, and the central part (of the base of the seismic isolation layer) is a steel frame (steel frame) C, and the rest is a wooden frame D By constituting the structure, the cost can be reduced.
In other words, in the “centrally controlled seismic isolation system” in which the control of the displacement of the earthquake or the wind fluctuation control is performed by the damper B-3 or the wind fluctuation fixing device B-4 in the center of the base of the seismic isolation layer. Since the stress is large with respect to the central frame, the cost is reduced by the structure of the steel frame (steel frame) C and the other wooden frame D. In the case of the central portion, there may be some deviation from the center (center of gravity, plane projection center of wind pressure). In some cases, the ratio to the entire plane of the seismic isolation layer is large or small.

Invention of Claim 3 is the seismic isolation structure of Claim 1 and Claim 2,
There are multiple installation parts such as restoration materials such as laminated rubber and springs, damping materials such as dampers, or wind sway fixing devices, etc., where the stress is large, and these are used as steel frame (steel frame) C, and the rest By using the wooden mount D, the cost can be reduced. The portions where the plurality of stresses are large may be further joined and connected by a steel frame. This is applied in the case of a structure having a large area.
The case where there are a plurality of portions having a large stress is, for example, a structure having a large area, and there are a plurality of dampers B-3 or a wind squeezing fixing device B-4 that perform seismic amplitude control or wind sway control. This is the case where they are placed and distributed. By configuring the upper part of the frame as a steel frame (steel frame) C because the stress is large, and using the other as a wooden frame D, due to the central control of the earthquake amplitude and wind fluctuation. Strength can be obtained and cost can be reduced.
Moreover, in order to transmit mutually the stress of the part with several big stresses, they may be connected with each other with a steel frame.
As described above, the adoption of the centrally controlled seismic isolation system in claims 2 and 3 concentrates the stress on the frame (during earthquake and wind) on the steel frame (steel frame) C part. In order to reduce the load on the other wooden frame D, it is suitable for a wooden frame.

In invention of Claim 4, in the seismic isolation structure of Claim 1, Claim 2, Claim 3,
There is a double base isolation plate (upper base isolation plate 1-u and lower base isolation plate 1-d) with a ball (bearing) 1-b or sliding part 1-s in between. When using “Seismic Isolation Bearing” (see FIG. 3 and FIG. 4), the size of the seismic isolation bearing is smaller than that of the single base isolation dish for the amount of displacement during the base isolation. The wooden frame D can be directly mounted on the upper surface, so that the problem of creep peculiar to the wooden structure does not occur, so that the wooden frame D is suitable.

The invention described in claims 5 to 11 is an invention relating to the joining of the seismic isolation device (seismic isolation support) and the wooden mount.
The seismic isolation device (seismic isolation bearing) carries the load from the building in a concentrated manner via a wooden frame. For this reason, joining the seismic isolation device (seismic isolation bearing) and the wooden gantry, and joining the wooden gantry to each other has a large and difficult load. In addition, it was difficult to join a steel frame (steel frame) due to the lack of material strength due to the wooden structure. Wooden structures are particularly small in bearing strength (indentation strength) and are easy to indent. For this reason, a support system that considers indentation is required for supporting a large load.

In the invention according to claim 5, sufficient rigidity (with respect to the load placed thereon) such as iron, wood, precast concrete, plastic composite material, ceramic, etc. is provided on the upper part of the seismic isolation device (seismic isolation support) 1. A thick plate-like lower support material 2 made of a certain material is placed, and the seismic isolation device (seismic isolation support) 1 and the lower support material 2 are joined with sufficient rigidity using bolts, welding, an adhesive, a diver, or the like. The wooden support 3 is supported by the lower support member 2 and the wooden supports 3 are joined to each other on the lower support member 2. The wooden support 3 is placed on the lower support member 2, and the problem of indentation due to the shearing connection by bolts is eliminated. This eliminates the problem of indentation due to the low bearing strength of the wood and enables high-strength joining.
With respect to the shape of the lower support member 2, it has sufficient rigidity to be placed on the seismic isolation device (seismic isolation support) 1 and to support the wooden frame 3. In addition, when not having sufficient rigidity, ribs made of H steel / angle material, wood, precast concrete, plastic composite material, ceramic, or the like may be attached in order to increase rigidity. In this manner, the sufficiently rigid joining between the plurality of wooden gantry 3 can be achieved by the intervention of the sufficiently rigid lower support member 2.
“Sufficient rigidity” in the lower support member 2 means that the stress generated by the movement of the ball (1-b) of the seismic isolation device 1 during the earthquake (base isolation) and the stress acting at all times are exempted. The thickness, size (width, length), and material characteristics that can be transmitted between the upper base isolation plate (1-u) of the seismic device 1 and the wooden gantry 3 between the two. It shows that it has. In order to increase the rigidity of the lower support member 2, ribs made of H steel / angle material, wood, precast concrete, plastic composite material, ceramic, or the like may be attached.
The “sufficiently rigid joint” between the seismic isolation device 1 and the lower support member 2 is an upper seismic isolation plate (1-u) of the seismic isolation device 1 using two or more bolts, welding, adhesive, gibber, or the like. ) And the lower support member 2 are joined so that there is almost no deviation due to shearing force or separation of the joined portions.

  In laterally penetrating shear bolt joining that penetrates the wooden gantry 3 in the horizontal direction (laterally), if the working stress is large, the penetration of the wood is large, making joining difficult. Therefore, there has been a demand for a joining method that avoids this. In the system according to the fifth aspect of the present invention, the wooden support 3 is placed on and supported on the upper portion of the lower support member 2, so that a horizontal through shear bolt connection is not required. Bolt (longitudinal penetration bolt) 5 that penetrates the lower support 2 and the wooden mount 3 in the longitudinal direction (vertical direction) through the wooden beam (corresponding to the tensile force and compressive force, no force acts in the shearing direction) This eliminates the problem of bolt penetration into the wood). Claim 6 is the invention.

  In addition, when the wooden support 3 is supported by the lower support material 2 and the wooden support 3 is not sufficiently joined on the lower support material 2, an iron material that is more resistant to tensile force on the upper parts of the wooden support 3, The lower support material 2, the wooden gantry 3 and the upper support material 4 are joined to each other across the upper support material 4 made of a material such as wood, precast concrete, plastic composite material, or ceramic. This ensures the joining of the wooden mounts 3. Claim 7 is the invention.

  The invention according to claim 8 is the invention according to claim 7, in order to avoid the upper support 4 being exposed on the upper surface of the wooden gantry 3. The nailing of the lower frame material, etc. in the construction method to the wooden frame 3) The horizontal frame 11 is provided at the upper position where the nails etc. do not reach, and the upper support material 4 is inserted into the slit 11 to install the wooden frame 3 It is easy to join the upper floor material, the lower frame material of the wall and the like to the wooden frame 3 by nailing or the like.

  As described above, in the case of a transverse through shear bolt joint, if the working stress is large, the penetration of the wood is large and the joint is difficult. Therefore, there has been a demand for a joining method that avoids this. In the system according to the fifth aspect of the present invention, the wooden support 3 is placed on and supported on the upper portion of the lower support member 2, so that a horizontal through shear bolt connection is not required. By simply joining the lower support member 2, the wooden frame 3, and the upper support member 4 of the invention according to claims 7 and 8 with the bolt 5 penetrating vertically (corresponding to the tensile force and compressive force). Get better. Claim 9 is the invention.

If the base isolation device (base isolation support) is large, place the base isolation device (base isolation support) inside the building so that the base isolation device (base isolation support) does not protrude outside the building. As a result, it is necessary to overhang the mount and place a superstructure pillar or wall on it. In such a structure, a wooden frame is not suitable.
In the invention described in claim 10, when the double seismic isolation plate isolated bearing 1-w is used in the seismic isolation structure described in claim 5, claim 6, claim 7, claim 8, claim 9 , The seismic isolation bearing is smaller (compared to the seismic isolation bearing of the single seismic isolation plate), and it is possible to mount the wooden frame 3 for placing the superstructure pillar or wall directly on the cantilever As a result, it is not necessary to overhang the mount and place a superstructure pillar or wall on top of it. It will be very suitable for wooden mounts.

The invention according to claim 11 is the seismic isolation structure according to claims 5, 6, 7, 8, 9, 10,
By making the joint part of the two members on the lower support member 2 into a joint 12 having a joint shape, one member (which is on the lower side in the joint part) is replaced with the other member (raised up). ) If the press-in type of joining is used, the wooden mounts 3 can be joined with higher strength.
In the wooden stand supported by the ball (1-b) of the seismic isolation device (seismic isolation bearing) 1, the wooden stand (on the ball) that comes above the support point (ball 1-b) is structurally A wooden stand that is stable but not supported by the upper portion of the ball 1-b (that does not ride on the ball) is unstable when the wooden stand alone is not provided (when the lower support member 2 is not provided). By connecting the joints of the two members on the lower support material 2 to a joint 12 having a joint, both members are supported by the ball 1-b (both members are on the ball). And more stability is obtained.
In other words, the joint position is provided at a position where one member (which is on the lower side of the joint portion) is always supported by the ball 1-b (being on the ball) with respect to the ball 1-b that moves in the event of an earthquake ( The lower member has a stable structure) and the other member (which is on the upper side in the joint) is supported by the stable lower member, and the upper member is also supported by the ball via the lower member. As a result, the stability is further increased, and the effect of pressing down the lower member to be lifted due to deformation or the like by the upper member is also obtained.

The invention described in claim 12 is the application of the invention described in claims 5, 6, 7, 7, 9, 10, and 11 to the steel frame.
That is, in joining the base isolation device (base isolation support) and the steel frame base (steel base), the upper part of the base isolation device (base isolation base) 1 is made of iron material (with respect to the load placed on it). ) The lower support member 2 made of a sufficiently rigid material is placed, the seismic isolation device (the seismic isolation support) and the lower support member 2 are joined with sufficient rigidity, and a steel frame is formed on the lower support member 2 A base 8 is provided, and the lower support member 2 and the steel frame base 8 are joined to each other with sufficient rigidity, and not only simplification of the joining is achieved, but also by the interposition of the lower support member 2 with sufficient rigidity, It is possible to join the steel frame mounts 8 with a sufficient rigidity.
“Sufficient rigidity” in the lower support member 2 means that the stress generated by the movement of the ball (1-b) of the seismic isolation device 1 during the earthquake (base isolation) and the stress acting at all times are exempted. The thickness, size (width, length), and material characteristics that can be transmitted between the upper base isolation plate (1-u) of the seismic device 1 and the steel frame 8 between them are shown. It shows that it has. As for the lower support member 2, ribs may be attached with H steel, an angle material or the like in order to increase rigidity.
“Sufficiently rigid joint” between the seismic isolation device 1 and the lower support material 2 means that the upper seismic isolation plate (1-u) and the lower support material of the seismic isolation device 1 are connected by two or more bolts or welding. It shows that it joins so that the shift | offset | difference by a shear force in a joint surface with 2 and a joining location may not leave | separate.
“Sufficiently rigid joining” between the lower support member 2 and the steel frame base 8 means that the shearing force between the lower support material 2 and the steel frame base 8 is shifted due to shear force when the stress is transmitted between the lower support material 2 and the steel frame base 8. It shows that it joins so that cross-sectional performances, such as a bending strength which the member which comprises the steel frame stand 8, may exhibit so that a joining location may hardly leave | separate and to exhibit.

The problems in this invention are the connection between the base of the base isolation layer and the base isolation device, and the connection between the bases of the base isolation layer, and simplification and standardization thereof.
Specifically, in the joining of the base of the seismic isolation layer and the base isolation device, and the joining of the bases of the base isolation layer, claims 5, 6, 7, 8, 9, 10, In the seismic isolation structure of items 11 and 12, the problem is solved by using the lower support material 2 of claims 5, 6, 7, 8, 9, 9, 10, 11 and 12. To do.
In other words, on the lower support material 2 joined to the seismic isolation device, simplification and standardization are performed by joining the gantry or joining the gantry together, and the dimensions can be adjusted. Naturally, this invention can be applied to both the steel frame and the wooden frame.

  The invention according to claim 14 is the seismic isolation structure according to claims 5, 6, 7, 8, 9, 10, 10, 11, 12, and 13; It is an invention of a base isolation device (base isolation support) in which the upper member of the device (base isolation support) 1 and the upper base isolation plate 1-u are integrated, and the base support 2 and the base isolation device (base isolation support) 1 This prevents duplication with the upper member or upper seismic isolation plate 1-u and eliminates waste.

The invention described in claim 15 is applied to a unit construction method used in an industrial prefabricated unit house or the like.
In a seismic isolation structure consisting of a unit structure such as a unit house, it is not sufficient to connect the seismic isolation device and the lower steel base of the unit to connect a plurality of units to make the units stable. You need something that complements it. In order to solve this problem, the lower support material described above can be used.
That is, in joining the base isolation device (base isolation support) and the lower steel base of the unit, there is sufficient iron material (with respect to the load on it) above the base isolation device (base isolation support) 1 A lower support member 2 made of a material having a sufficient rigidity is placed, and a base isolation device (base isolation support) 1 and a lower support member 2 are joined with sufficient rigidity, and further, one on the lower support member 2 Alternatively, a lower steel base (unit lower steel base) 9 of a plurality of units is provided, and the lower support member 2 and the unit lower steel base 9 are joined with sufficient rigidity. As described above, by the interposition of the sufficiently rigid lower support member 2, it is possible to sufficiently bond the (lower) unit lower steel foundations, and to enable a stable structure between the (lower) units. The seismic isolation device can be directly attached to units such as unit houses.

It shows that it joins so that cross-sectional performances, such as a bending strength which the member which comprises the lower steel frame base 9 has, can exhibit so that a shift | offset | difference and a joining location may not leave | separate substantially.

The invention as set forth in claim 16 is a base-isolated structure comprising the unit construction method according to claim 15, wherein the centrally controlled seismic isolation system is a portion where the stress is large (compared to other portions) (the base isolation layer). With respect to the central portion (of the plane), the invention of claim 15 is insufficient. Therefore, by providing a steel frame (steel frame) 8 at the central part (on the plane of the seismic isolation layer) where stress is large, it becomes possible to cope with the stress.
As described in the second and third aspects of the invention, the control of the displacement of the earthquake or the wind fluctuation control is performed by the damper B-3 or the wind fluctuation fixing device B-4 at the central portion in the plane of the base isolation layer. In the “centrally controlled seismic isolation system”, since the stress is large in the central portion where the control is performed, it can be solved by providing a steel frame (steel frame) 8 structure. In the case of the central portion, there may be some deviation from the center (center of gravity, plane projection center of wind pressure). In some cases, the ratio to the entire plane of the seismic isolation layer is large or small.

The invention according to claim 17 is an invention of a seismic isolation structure in which the base of the base isolation layer can be constituted by the wooden base D, and the cost can be reduced.
In the base of the base isolation layer, a plurality of wooden bases D should be placed at the part where the stress is great due to the installation of restoring materials such as laminated rubber and springs, damping materials such as damper B-3, or wind sway fixing device B-4. Thus, the yield strength and rigidity of the wooden gantry D against stress are secured.

The invention described in claim 18 is an invention relating to the joining of the seismic isolation device (base isolation support) 1 and the wooden gantry 3 in the base isolation structure according to claim 17.
In joining the base isolation device (base isolation support) 1 and the wooden base 3, the damper B- is used by using the method of connecting the base isolation device (base isolation support) and the wooden base according to claims 5 to 11. High-strength joining of the seismic isolation device (seismic isolation support) that supports the part with high stress due to the installation of the damping material such as 3 or the wind sway fixing device B-4 is possible. This is because the vertical stress acting from the damper B-3 and the wind sway fixing device B-4 is joined with the bolt 5 penetrating the seismic isolation device (base isolation bearing) 1 and the wooden frame 3 vertically. As a result, resistance is exerted by the tensile force acting on the bolt 5, so that the problem that the bolt is sunk into the wood and strong strength cannot be obtained is solved.

In the invention according to claim 19, in the joining of the seismic isolation device (damper B-3, wind sway fixing device B-4, etc.) of the part having a large stress in the seismic isolation structure according to claim 17 and the wooden gantry 3, It is an invention that enables stress to be transmitted.

This joint reinforcing member 10 has a length that is about the distance between the damper B-3 and the wind sway fixing device B-4, and connects the damper and the wind sway fixing device to the wooden frame. It joins with the volt | bolt 5 of a direction.
Due to the mechanism of the seismic isolation system, the stress from the damper B-3 and the stress from the wind sway fixing device B-4 do not act simultaneously, and the damper and the wind sway fixing device are connected by the joint reinforcement member 10. , Damper, wind sway fixing device, against the respective stress, the seismic isolation device (damper B) via the joint reinforcing member 10 by both the lateral bolt 5 above the damper and the lateral bolt 5 above the wind sway fixing device. -3, wind sway fixing device B-4 and the like) and the wooden frame 3 can efficiently transmit stress.

The invention according to claim 20 provides
Seismic isolation devices such as seismic isolation support 1 that supports a portion of high stress due to installation of damping material such as damper B-3 or wind sway fixing device B-4 via wooden gantry 3, and a damper that generates the stress greatly The invention relates to the joining of the seismic isolation device such as B-3 and the wind sway fixing device B-4 and the wooden gantry 3.
Seismic isolation devices such as seismic isolation support 1 that supports a portion of high stress due to installation of damping material such as damper B-3 or wind sway fixing device B-4 via wooden gantry 3, and a damper that generates the stress greatly When joining the seismic isolation device such as B-3 and the wind sway fixing device B-4 and the wooden gantry 3, a single plate-like continuous member (hereinafter referred to as a plate-like continuous member) 13 such as a continuous piece of wood is used. Therefore, efficient joining is possible.
Joining of a base-like continuous member 13 with a base-isolation device such as a base-isolation support 1 that supports, via a wooden gantry 3, a portion with high stress caused by installation of a damping material such as a damper B-3 or a wind sway fixing device B-4 The bolt shaft part by the shear bolt joint is obtained by joining the damper B-3 and the wind sway fixing device B-4 through the wooden frame 3 so as to be a tension bolt joint against the vertical stress acting on the wooden base 3. The problem of sinking into the wood and eliminating the strong strength is solved. It should be noted that stronger shear strength can be obtained by using a combination of the gibber 14 and the like at the time of tensile bolt joining.
The plate-like continuous member 13 is connected to the seismic isolation device such as the damper B-3 and the wind sway fixing device B-4, but the shear bolt joint is used. Is possible. Furthermore, by joining the flat plate-like continuous member 13 and the wooden gantry 3 with adhesive, bolts, nails, etc., the vertical and horizontal stresses acting from the damper B-3 and the wind sway fixing device B-4 are flattened. It is transmitted from the continuous member 13 to the wooden frame 3 and resists.

  The invention described in claims 1 to 4 is an invention relating to the structure of the base of the seismic isolation layer.

In invention of Claim 1,
In the base of the seismic isolation layer, a steel frame base (steel base) is placed on the part where the stress is large (compared to other parts) by installing a restoring material such as laminated rubber and spring, a damping material such as a damper, or a wind sway fixing device.

Further, in the horizontal penetration shear bolt joining, when the working stress is large, the penetration of the wood is large and the joining becomes difficult. Therefore, there has been a demand for a joining method that avoids this.

  In the invention described in claim 6, since the wooden frame 3 is mounted on and supported on the upper portion of the lower support member 2, a laterally penetrating shear bolt joint is not required. It is only necessary to join the lower support member 2 and the wooden gantry 3 to each other with a bolt 5 penetrating vertically (corresponding to a tensile force and a compressive force).

If the wooden base 3 is composed of two or more members, the joints between the wooden bases 3 are insufficient. If the wooden bases 3 are not sufficiently joined together, the upper parts of the wooden bases 3 are further made of iron, wood, precast, which is a material with a strong tensile force. An upper support material 4 made of a material such as concrete, plastic composite material, or ceramic is provided across the lower support material 2, the wooden support 3, and the upper support material 4. This ensures the joining of the wooden mounts 3.
Further, in the horizontal penetration shear bolt joining, when the working stress is large, the penetration of the wood is large and the joining becomes difficult. Therefore, there has been a demand for a joining method that avoids this.

  The invention according to claim 8 is the invention according to claim 7, in order to avoid the upper support 4 being exposed on the upper surface of the wooden gantry 3. By nailing the wooden frame 3 of the lower frame material etc. in the construction method) by providing a horizontal slit 11 at the upper (intermediate) position where nails etc. do not reach, and inserting the upper support material 4 into the slit 11 and installing it, This facilitates joining of the floor material on the wooden gantry 3 or the lower frame material of the wall to the wooden gantry 3 by nailing or the like.

Arranged in the form of central control.

  54. Example 29 of FIG. 55 is the seismic isolation device (seismic isolation support) 1 and the wooden frame 3 according to claims 18 and 19, and the seismic isolation device (damper B-3, wind sway fixing device B-4, etc.) FIG. 54 is a partial detailed perspective view (FIG. 54) and an exploded perspective view (FIG. 55) related to the joining of the frame and the wooden gantry 3.

  The invention according to claim 18 is provided in the upper part of the base isolation device (base isolation support) 1 in the joint of the base isolation device (base isolation support) 1 and the wooden base 3 of the part where the stress is large in the base of the base isolation layer. It is made of a material that is sufficiently rigid (for loads on it and for loads from dampers, wind sway fixing devices, etc.) such as iron, wood, precast concrete, plastic composites, and ceramics. The lower support material 2 is placed, the seismic isolation device (seismic isolation support) 1 and the lower support material 2 are joined with sufficient rigidity by bolts, welding, etc., and the lower support material 2 is used to attach a plurality of wooden gantry 3 In addition, the wooden supports 3 (multiple, orthogonal, etc.) are joined to each other by the upper support 4 on the lower support 2. In this case, the wooden support 3 can be placed on the lower support material 2 and further, the bolts 5 vertically passing through the lower support material 2, the wooden support 3 and the upper support material 4 (corresponding to the tensile force and compressive force). ) Resistant to the vertical stress from damper B-3 and wind sway fixing device B-4 by joining, the bolt wood in the case of shear bolt joining because it resists by pulling the bolt 5 penetrating vertically. This eliminates the intrusion, eliminates the indentation problem due to the low bearing strength of the wood, and enables high strength bonding.

According to the nineteenth aspect of the present invention, the damper B-3, the wind sway fixing device B-4 and the like and the wooden gantry 3 are joined by the lateral bolt 5 through the groove-shaped joining reinforcing member 10. is there. The joint reinforcing member 10 has a length approximately equal to the distance between the damper B-3 and the wind sway fixing device B-4, and is installed at the lower part of the wooden beam along the length direction of the wooden beam to fix the damper and the wind sway. The device is connected, and the damper, the wind sway fixing device and the wooden gantry 3 are joined.
Due to the mechanism of the seismic isolation system, the stress from the damper B-3 and the stress from the wind sway fixing device B-4 do not act simultaneously, and the damper and the wind sway fixing device are connected by the joint reinforcement member 10. It is possible to resist the damper, the wind sway fixing device, each of the individual bolts with both the lateral bolt 5 of the damper portion and the lateral bolt 5 of the wind sway fixing device portion, and an efficient joint type It has become.
The transverse bolt 5 in this joint is a shear bolt. However, the vertical direction stress from the damper B-3, wind sway fixing device B-4, etc., is reinforced from the damper or wind sway fixing device. Since the surface pressure is directly transmitted to the wooden gantry 3 through the member 10, the bolt does not sink into the wood.
For horizontal stress from the damper B-3, wind sway fixing device B-4, etc., the horizontal stress in the direction orthogonal to the members above the damper B-3, wind sway fixing device B-4 The stress is hardly applied to the bolt 5 in the lateral direction because it is transmitted by the surface pressure of the joint reinforcing member 10 and the orthogonal beam. Wood against the horizontal stress in the member direction above the damper B-3 and wind sway fixing device B-4, while the lateral bolt 5 functions as a shear bolt, the applied direction is strong against denting It is possible to bond with higher strength than the shear bolt joint in the direction perpendicular to the fiber of wood, which is generally used for joining the beams.

  A thirty-sixth embodiment shown in FIG. 56 to FIG. 58 includes a seismic isolation device such as a seismic isolation bearing 1 according to claim 20, a seismic isolation device such as a damper B-3 and a wind sway fixing device B-4, FIG. 56 is a general view (FIG. 56), a partial detailed perspective view (FIG. 57), and an exploded perspective view (FIG. 58) of the connection with the joint.

The invention according to claim 20 provides
Seismic isolation devices such as seismic isolation support 1 that supports a portion of high stress due to installation of damping material such as damper B-3 or wind sway fixing device B-4 via wooden gantry 3, and a damper that generates the stress greatly B-3, the seismic isolation device such as the wind sway fixing device B-4, and the wooden gantry 3 are joined through a single plate-like continuous member (flat plate-like continuous member) 13 such as a single piece of wood. Is.
This flat plate-like continuous member 13 is installed between a base-isolated device such as a base-isolated bearing 1, a damper B-3, a wind sway fixing device B-4, etc., and a wooden gantry 3 on its upper part, and is a flat plate-like continuous member. 13 is joined to the seismic isolation device at the lower part and the wooden frame at the upper part.
The continuous member 13 having a flat plate shape is particularly effective in stress transmission.
When the continuous member 13 has a flat plate shape and is installed so as to be parallel to a horizontal plane, the continuous member 13 has high proof stress and rigidity against a horizontal stress. Therefore, it is possible to exert a high effect on stress transmission with respect to horizontal stress from the damper B-3, the wind sway fixing device B-4, and the like.
Further, when the continuous member 13 and the wooden gantry 3 are joined and integrated, if a structural plywood or the like is further installed on the upper surface of the wooden gantry as a floor base material by a nail or an adhesive, the wooden gantry 3 It has flange material on the top and bottom, and exhibits high bending strength and bending rigidity against vertical stress acting from damper B-3, wind sway fixing device B-4 and the like. At that time, the wooden frame 3 resists a vertical shearing force as a web material. In this way, the continuous member 13 has a flat plate shape, and particularly has an effect in terms of stress transmission when installed in the lower part of the wooden gantry so as to be parallel to the horizontal plane.
When joining seismic isolation devices such as seismic isolation bearings 1 to the flat plate-like continuous member 13, against the vertical stress transmitted through the wooden frame 3 from the damper B-3, wind sway fixing device B-4, etc. By using tension bolt bonding, the bolt does not sink into the wood in the case of shear bolt joining, and the problem of indentation due to the low bearing strength of the wood is eliminated, and high strength joining can be performed. It should be noted that a higher shear strength can be obtained by using a combination of the gibber 14 and the like in this bolt joint. This is the case where only the flat plate-like continuous member 13 resists horizontal stress from the damper B-3, the wind sway fixing device B-4, etc., and the base-isolated device such as the base-isolated support 1 and the flat plate-like continuous member This is useful when shearing force is applied to the joint.
When the damper B-3, the wind sway fixing device B-4, etc. and the flat plate-like continuous member 13 are joined, the shear bolt is applied to the horizontal stress from the damper B-3, the wind sway fixing device B-4, etc. Although it is a joint, it is possible to obtain a high shear strength by using the diver 14 or the like together. It is also possible to increase the number of shear bolts by joining the damper B-3, the wind sway fixing device B-4, etc., and the flat plate-like continuous member 13 via the joining reinforcing steel plate 15 such as iron. is there.
When the flat plate-like continuous member 13 alone has sufficient strength and rigidity against the stress in the horizontal direction from the damper B-3, the wind sway fixing device B-4, etc., the flat plate-like continuous member 13 and the wooden frame 3 is connected to both ends (seismic isolation bearing 1 part) with a longitudinally penetrating bolt 5 or the like, with respect to the vertical acting stress from the damper B-3, wind sway fixing device B-4 or the like, Since stress is directly transmitted from the flat plate-like continuous member 13 to the wooden frame 3 by surface pressure, it is not necessary to join the flat plate-like continuous member 13 and the wooden frame 3 over the entire length. If the flat plate-like continuous member 13 and the wooden gantry 3 are joined and integrated over the entire length with adhesive, bolts, nails, etc., the vertical acting stress from the damper B-3 and the wind sway fixing device B-4 It can resist with higher yield strength and rigidity. Furthermore, even with respect to the horizontal acting stress from the damper B-3 and the wind sway fixing device B-4, the flat plate-like continuous member 13 is joined to the wooden frame, and the wooden frame is joined to the wooden frame in the orthogonal direction. Since stress is transmitted to the wooden frame, it is possible to transmit stress efficiently with higher proof stress and rigidity. The flat plate-like continuous member 13 and the wooden gantry 3 can be integrated to obtain a combined effect of the cross sections of the two. Therefore, the damping material such as a damper that generates a large stress or the wooden gantry of the installation part of the wind sway fixing device or the like The cross section of the gantry can be reduced and the cost can be reduced.
