A fixing board holding frame 8 and a floating board holding frame 11 are assembled by enveloping a ring spring block in which a mounting shaft is set in parallel to the upper story beam 3. When these two frames produce a relative displacement in the direction of the ring spring block mounting shaft, a ring spring mounting body 7 is formed in such a fashion that a compression force may act on the ring spring block. The fixing board holding frame 8 of the ring spring mounting body 7 is installed in one piece with the upper story beam 3, thereby connecting the floating board holding frame 11 of the ring spring mounting body 7 to a bending part of the angle- made frame 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration-proof reinforcing device for a building using a ring spring that absorbs vibration energy of the building due to an earthquake or wind and increases the yield strength of the building.

[0002]

2. Description of the Related Art For repeated loads such as seismic force and wind pressure that are concentrated in a short period of time, it is necessary to improve the rigidity of a building and to increase the vibration energy absorption capacity. is there. It is good for a super-high-rise building where the frame itself has the ability to absorb vibration energy, but for a medium-high-rise building, the frame alone cannot sufficiently absorb the vibrational energy regardless of the constituent material and structural form of the frame.

For this reason, in middle-high-rise buildings, various types of vibration damping devices have been used to absorb vibration energy. However, conventional vibration damping devices are designed only to absorb vibration energy. Therefore, it is not suitable for use in enhancing the toughness of buildings.
In particular, when reinforcing an existing medium-high-rise building, it is possible to make use of the proof stress of the existing structure and to resist the load together with the skeleton, that is, the proof strength is large and the rigidity can be adjusted. What can be done and has a large vibration energy absorption capability is required.

Among the conventional vibration damping devices, the following 1) to 5) are provided for the device for absorbing the vibration energy, which is installed between the foundation and the upper structure or in the frame of the structure. There is. 1) Utilizing deformation of steel or lead material. 2) Using the viscous resistance of a viscous body. 3) Using a hydraulic cylinder. 4) Using friction resistance.

[0005]

In the case of the conventional vibration damping device 1), until the steel material or the lead material reaches the yield point, it resists the load together with the frame according to the deformation of the frame, but during that period the vibration energy It has almost no absorption capacity. Further, when the steel material or the lead material exceeds the yield point, its plastic deformation absorbs the vibration energy, but instead, it loses the ability to withstand the load together with the frame according to the deformation of the frame. Further, since the plastically deformed steel material or lead material must be replaced, there is a problem in terms of maintenance.

In the case of the conventional vibration damping device 2), the viscous resistance of the viscous body depends on temperature, frequency and amplitude. Therefore, it is effective for damping vibrations such as mechanical vibrations that vibrate under certain conditions, but is not suitable for applications in which toughness is added to a structure in cooperation with the structure of the structure where the resistance increases according to the amount of deformation. Not suitable.

In the case of the conventional vibration damping device 3), since the resistance force increases in proportion to the speed, as in the case of 2) above, the resistance force increases in accordance with the deformation amount. It is not suitable for the purpose of adding toughness to a structure in cooperation with the skeleton.

In the case of the conventional vibration damping device 4), since friction does not occur until the force acting on the device reaches a certain magnitude, during that time, rigidity is added to the frame as in 1) above. However, it does not have the ability to absorb vibration energy. When the force acting on the device exceeds a certain value, friction occurs and the vibration energy is absorbed, but rigidity cannot be added. Further, the operated device cannot return to its original state by itself, which causes a problem in maintenance.

From the above, the problems to be solved by the invention are as follows i) to iv). i) From medium to small earthquakes to large earthquakes, it must support the seismic force in cooperation with the frame of the building and have the ability to absorb vibration energy against vibrations caused by earthquakes or wind. ii) Maintenance work is easy without the need for equipment replacement and restoration work. iii) The installation cost is economically acceptable. iv) The performance of the equipment is stable and can be implemented with the current technical level.

[Means for Solving the Problem and Its Action]

(No. 1) Means: The chevron frame 5 is installed by connecting both projecting ends to both ends of one beam on the frame of the structure of the building formed by the pillar 1 and the beam. The fixing plate holding frame 8 is surrounded by the ring spring block 16 whose mounting shaft is set parallel to the beam in the construction plane.
And the floating plate holding frame 11 are combined, and when these two holding frames cause relative displacement in the direction of the mounting axis of the ring spring block 16, the ring spring mounting body 7 is formed so that a compressive force acts on the ring spring block 16. To do. The fixing plate holding frame 8 of the ring spring mounting body 7 is connected to the other beam of the frame of the building, and the floating plate holding frame 11 of the ring spring mounting body 7 is connected to the bent portion of the chevron frame 5. To do.

Action: When a building structure is deformed in the frame due to seismic force or wind pressure acting on the structure, the bent portion of the mountain frame 5 is displaced relative to the other beam of the structure frame. Raise it. As a result, in the ring spring mounting body 7, the floating plate holding frame 11 is different from the fixed plate holding frame 8 in the ring spring block 1.
6 Relative displacement occurs in the direction of the mounting axis, and the ring spring block 1
6 is compressed. When the direction of deformation of the frame of the building changes, in the ring spring mounting body 7, the floating plate holding frame 11 makes relative displacement in the opposite direction with respect to the fixed plate holding frame 8, and once returns to the original shape, Continue relative displacement. When the ring spring mounting body 7 returns to its original shape, the ring spring block 16
Since the compressive force does not work on the ring spring block 16, the compressed ring spring block 16 extends back to its original shape. When the floating plate holding frame 11 makes relative displacement with respect to the fixed plate holding frame 8 in the opposite direction,
The compression force acts on the ring spring block 16 again, and the ring spring block 16 contracts. In this way, when vibration deformation due to seismic force or wind pressure occurs in the frame of the building, the ring spring block 16 expands and contracts twice per cycle. The amount of deformation of the ring spring block 16 is determined by the compression force acting on the ring spring block 16, and if the compression force is small, the amount of deformation is small.
The larger the compressive force, the larger the amount of deformation. Further, the ring spring block 16 has the ability to absorb vibration energy due to the expansion and contraction friction between the outer ring 29 and the inner ring 30, and also has the ability to return to the original shape when unloading. Therefore, the vibration-proof reinforcing device for a building using the ring spring of the present invention has a resistance force proportional to the amount of deformation of the frame of the building, a vibration energy absorbing ability, and an ability to restore the original shape by itself.

(No. 2) Means: Both ends of one beam are connected to both ends of one beam, and the other beam is connected to the other beam of the other, to the construction surface of the frame of the building formed by the column 41 and the beam. The X-shaped frame 45 is installed by connecting the projecting end portions so as to be movable within the construction plane.
The bearing 54 is connected to the rotating shaft 57 provided at the intersection of the X-shaped frame 45, and the triangular frame 47 is attached so as to be rotatable with respect to the X-shaped frame 45. The central projecting end of the triangular frame 47 facing the other beam is connected to the other beam so as to be pivotable and vertically movable, and the left and right projecting ends are movably connected to the other beam within the construction plane. A ring spring mounting body 7 formed in the same manner as described in (1) above is connected to a fixing plate holding frame 8 on one beam, and is free to move to the projecting end of the triangular frame 47 facing the one beam. The plate holding frame 11 is installed so as to be pivotally and vertically movable.

Action: Seismic force or wind pressure is applied to the building, and one beam of one frame of the building is
In the triangular frame 47, when the relative displacement is generated in the frame, the bearing portion 54 moves together with the X-shaped frame 45 integrally with one beam, and the central projecting end connected to the other beam of the other beam. Moves together with the beam. As a result, the triangular frame 47 rotates with respect to the X frame 45, and the tip end of the ring spring mounting body 7 connected to the floating plate holding frame 11 is displaced relative to one beam. This relative displacement amount is determined by the distance from the bearing portion 54 to the connecting portion of the other beam and the bearing portion 5
4 depends on the distance from the connecting portion of the ring spring mounting body 7, and if the latter is larger than the former, the relative displacement amount of the other beam with respect to one beam is amplified and transmitted to the ring spring mounting body 7. The subsequent operation of the ring spring mounting body 7 is the same as the above-mentioned operation (No. 1).

(Part 3) Means: A hook-shaped or T-shaped reinforcing structure 64 formed by rigidly connecting a vertical member to a horizontal member is arranged on the outer frame of a building in parallel with the frame.

Since the vertical members and the horizontal members are rigidly joined, when the vertical members rotate, the horizontal members also rotate, and the projecting end portions of the horizontal members make relative displacement in the vertical direction with respect to the skeleton of the building which faces them. The relative displacement varies depending on the distance from the node of the reinforcing structure 64 to the tip of the vertical member and the distance from the node to the tip of the horizontal member. If the latter is larger than the former, the tip of the vertical member with respect to the node is larger. Is amplified and transmitted to the ring spring mounting body 67.

Action: When the structure is deformed into the frame by seismic force or wind pressure, the cross members of the hook-shaped frame 103 are integrated with the frame of the connected structures. Therefore, the projecting end portion of the vertical member of the hook-shaped frame 103 rigidly joined to the horizontal member causes a relative displacement in the horizontal direction with respect to the frame of the building which faces it. As a result, in the ring spring mounting body 107, the floating plate holding frame 111 connected to the projecting end of the vertical member relatively displaces with respect to the fixed plate holding frame 108 connected to the frame of the building, and the ring spring block. 76 is compressed.

The nodal points and the ends of the vertical members are connected to the building. Surrounding the ring spring block 76 with the mounting axis set in the vertical direction, a fixed plate holding frame 108 and a floating plate holding frame 111 are combined, and these two holding frames make relative displacement in the direction of the ring spring block 76 mounting axis.

Along with this, the horizontal member rigidly joined to the vertical member rotates, and the projecting end portion of the horizontal member relatively displaces in the up-down direction with respect to the frame of the building facing the horizontal member. As a result, in the ring spring mounting body 107, the floating plate holding frame 111 connected to the projecting end portion of the cross member relatively displaces with respect to the fixed plate holding frame 108 connected to the frame of the building, and the ring spring block. 7
6 is compressed. The subsequent operation of the ring spring mounting body 107 is the same as the above-mentioned operation (No. 1).

(Part 6) Means: A gate-shaped or step-shaped reinforcing structure 1 formed by rigidly joining vertical members to both ends of a horizontal member.
04 is placed on the framing surface along the outside of the frame of the building, and the two nodes of the cross member and the longitudinal member are connected to the building.

Action: When the building frame is deformed within its structure due to seismic force or wind pressure acting on the structure, the cross members of the reinforcing structure 104 become integral with the frame structure of the connected structure. Since the two vertical members of the portal structure or the step-shaped reinforcing structure 104 rigidly joined to both ends of the cross member are connected to each other with respect to the skeletons of the structures to be opposed, Relative displacement occurs in the horizontal direction within the construction plane. As a result, in the two ring spring mounting bodies 107, the floating plate holding frame 111 connected to the projecting end of the vertical member makes relative displacement with respect to the fixed plate holding frame 108 connected to the frame of the building. The ring spring block 76 is compressed. The subsequent operation of the ring spring mounting body 107 is the same as the above-mentioned operation (No. 1).

[0030]

Since the present invention is configured as described above, it has the following effects. In the case of the first embodiment, since the triangular frame is formed by the mountain frame 5 and the beam 2 on the lower floor, a load acts to form a rectangle composed of the left and right columns 1, the beam 2 on the lower floor, and the beam 3 on the upper floor. Even if the ramen frame is deformed into a rhombus shape, this triangular frame is hardly deformed. Therefore, when the rectangular frame frame is deformed into a rhombus shape, the top of the mountain frame 5 is displaced relative to the beam 3 on the upper floor. As a result, in the ring spring mounting body 7, the floating plate holding frame 11 connected to the top of the chevron frame 5 is attached to the ring spring block 16 with respect to the fixed plate holding frame 8 installed integrally with the beam 3 on the upper floor. Relative displacement occurs in the direction of the mounting axis. 20 and 21 are cross-sectional views showing a state in which the floating plate holding frame 11 is displaced relative to the fixed plate holding frame 8 and the ring spring block 16 is compressed. Before they are relatively displaced, as shown in FIG. 3, the left and right floating plates 23 sandwiching the ring spring block 16 are both fixed plates 1.
It is in a state close to 9. At this time, the initial pressure regulator 32
Due to this, an appropriate pressure is applied to the ring spring 31.
FIG. 20 shows a state in which the floating plate holding frame 11 is displaced leftward relative to the fixed plate holding frame 8. The floating plate 23 at the left end of the ring spring block 16 is prevented from moving by the fixed plate 19, while the floating plate 23 at the right end of the ring spring block 16 is moved in the floating plate moving groove 24 of the floating plate side girder 18.
It moves together with the floating plate holding frame 11 in a state of being hung on the groove edge of. As a result, each ring spring block 16 is compressed. When the direction of the load changes and the deformed frame frame of the building returns to the original shape, the ring spring mounting body 7 also returns to the original shape, and the state shown in FIG. 3 is obtained. When the frame frame of the building is deformed into a rhombus shape in the opposite direction to the above, in the ring spring mounting body 7, as shown in FIG. 21, the floating plate holding frame 11 is opposed to the right side relative to the fixed plate holding frame 8. Displace. At this time, the floating plate 23 at the right end of the wheel spring block 16 is prevented from moving by the fixed plate 19, while the floating plate 23 at the left end of the wheel spring block 16 is moved in the floating plate moving groove of the floating plate side girder 18. Two
It moves together with the floating plate holding frame 11 in a state where it is hooked on the groove edge of No. 4. As a result, each ring spring block 16 is compressed. In this way, the ring spring block 16 is compressed regardless of which side of the construction frame frame is deformed, and when the frame frame returns to its original shape, the ring spring block 16 also returns to its original shape. In the case of the first embodiment, since the relative displacement amount of the beam 3 on the upper floor to the beam 2 on the lower floor is small, a ring spring mounting body having a large resistance force against small deformation and a vibration energy absorption capability is required. Therefore, the ring spring mounting body 7 of the first embodiment
Then, a compressive force is simultaneously applied to a plurality of independent ring spring blocks 16 so as to have a large resistance force and a large vibration energy absorption capability with respect to a small displacement amount.

In the case of the second embodiment, since the integral connecting portion 46 at the upper end of the X-shaped frame 45 is restrained from moving vertically and horizontally by the vertical frame 49 and the fixing plate holding frame 8 of the ring spring mounting body 7, It is in a state of being connected to the joint portion between the pillar 41 and the beam 43 on the upper floor. Therefore, when the rectangular frame frame of the building is deformed into a rhombus shape, the rotating shaft 57 of the intersection of the X-shaped frame 45 is integrated with the beam 43 on the upper floor and is relatively opposed to the beam 42 on the lower floor. Displace. As a result, the intermediate bearing portion 54 is rotatably connected to the rotation shaft 57 of the X-shaped frame 45, and the central horizontal frame connecting portion 55 at the lower end of the horizontal frame 48 integrally formed with the beam 42 on the lower floor. The triangular frame 47 rotatably and vertically movable is connected to the rotating shaft 59 inclining in the moving direction of the upper beam 43, and the elastic connecting portion 52 at the upper end of the triangular frame 47 is connected to the upper beam 43. Relative displacement with respect to. If the distance from the bearing portion 54 of the triangular frame 47 to the central horizontal frame connecting portion 55 at the lower end is 1 and the distance from the bearing portion 54 to the elastic connecting portion 52 at the upper end is 2, then the beam 43 on the upper floor is When the beam 42 on the lower floor undergoes acm relative displacement,
Elastic connection part 5 of triangular frame 47 to beam 43 on the upper floor
2 causes a relative displacement of 2 acm. At this time, the magnitude of the horizontal force acting on the elastic connecting portion 52 of the triangular frame 47 is
It is half the magnitude of the horizontal force acting on the central horizontal frame connecting portion 55. The X-shaped frame 45 and the triangular frame 47 are rigidly formed so as not to be deformed in the frame of the structure of the building, and the tip 51 of the X-shaped frame 45 and that of the triangular frame 47 are lateral. Since each of the frame connecting portions 56 is connected to the horizontal frame 48 so as to be movable only within the construction surface, it is not twisted and deformed outside the construction surface. Therefore, when the elastic connecting portion 52 of the triangular frame 47 relatively displaces with respect to the upper beam 43, in the ring spring mounting body 7, the fixing plate holding frame 8 installed integrally with the upper beam 43 is provided.
On the other hand, the floating plate holding frame 11 connected to the elastic connecting portion 52 of the triangular frame 47 is relatively displaced, and the ring spring block 16 is compressed. The structure in which the ring spring block 16 is compressed regardless of which side of the frame structure of the building is deformed is the same as that of the ring spring mounting body 7 of the first embodiment. In the case of the second embodiment, since the relative displacement amount of the beam 43 on the upper floor to the beam 42 on the lower floor is small as in the case of the first embodiment, the relative displacement of the ring spring mounting body 7 by the X-shaped frame 45 and the triangular frame 47. Amplify the amount and mount the ring spring 7
The load acting on is reduced. Therefore, the second embodiment
Even if the number of the ring spring blocks 16 installed is smaller than that of the first embodiment, the same effect as that of the first embodiment can be obtained.

In the case of the third embodiment, the purpose is to reinforce the frame structure in the girder direction outside the building.
It is suitable for reinforcement of buildings such as schools with large span wall beams 62. When the outer frame of the building forming the rectangular frame with the wall columns 61 and the wall beams 62 receives a load and is deformed into a rhombus shape, the nodes of the vertical members and the horizontal members and the lower ends of the vertical members are connected to the frame of the building. In the reinforcing structure 64 of the hook-shaped frame 63 or the T-frame 65 connected to the respective nodes, the vertical members rotate slightly together with the wall columns 61 of the building, and the horizontal members rigidly joined to the vertical members face each other. Rotate against the building wall beam 62. As a result, the elastic connecting portion 72 at the tip of the cross member causes relative displacement upward or downward with respect to the frame of the building to which it faces. Therefore, in the ring spring mounting body 67, the fixed plate holding frame 68 connected to the elastic connecting portion 72 of the transverse member is moved upward or downward with respect to the floating plate holding frame 71 installed integrally with the frame of the building. Causes relative displacement,
The ring spring block 76 is compressed. As in the case of the ring spring mounting body 7 of the first embodiment, the compression force acts on the ring spring block 76 regardless of which side of the structure the outer frame of the building is deformed. In the case of the present embodiment, since the reinforcing structure 64 is installed outside the frame of the building, the structure of the integral connecting portions 66 and 70 of the reinforcing structure 64 ensures that the load acting on the frame of the building is reinforced. It must be able to be transferred to the body 64. The integral connecting portions 66 provided at the nodes of the horizontal members and the vertical members of the reinforcing structure 64 are embedded on the back side of the reinforcing structure 64 in the steel fixed disk 73 fixed to the frame of the building by a large number of bolts. Plated steel disc 74 secured
Is rotatably fitted, one end is fixed to the center of the fixed disk 73, and the large-diameter holding bolt 80 provided by penetrating the reinforcing structure 64 separates the dish-shaped disk 74 and the reinforcing structure 64 from the fixed disk 73. Is held to not. Therefore, the integral connecting portion 66 can sufficiently withstand a large shearing force that acts, and can reasonably transfer the load acting on the frame of the building to the reinforcing structure 64. In addition, in the integral connecting portion 70 at the projecting end of the vertical member, the tenon 88 inserted between the tenon receivers 84 can be rotated within the construction surface of the reinforcing structure 64, and
Since it can move up and down, bending moment and axial force generated in the frame of the building are not transmitted to the longitudinal member. In the present embodiment, when the length of the vertical members of the reinforcing structure 64 is set to the length of one layer of the frame of the building, if the length of the horizontal members is made longer than the length of the vertical members, the ring spring mounting body 67. The relative displacement in is amplified, and the same effect as that of the above-described second embodiment can be obtained. Further, when the length of the vertical member of the reinforcing structure 64 is set to the length of two layers of the frame of the building, even if the length of the horizontal member is about the same as the length of the vertical member, the relative displacement in the ring spring mounting body 67 is reduced. It becomes larger, and the same effect as described above can be obtained.

In the case of the fourth embodiment, it is suitable to reinforce the frame in the beam direction of the building, and when the frame in the beam direction has a plurality of spans, the hook-shaped frame 103 is used. The frame 105 is a step frame 1 in the case of a step frame.
It is effective to use 14 for each of the reinforcing structures 64. In either case, the two nodes of the reinforcing structure 64, or the nodal point and one node, are connected to the nodes of the frame of the building.
Therefore, when the rectangular frame of the building receives a load and is deformed into a rhombus shape, the elastic connecting portion 112 provided at the projecting end portion of the reinforcing structure 104 causes the elastic frame 112 to be in the frame of the frame with respect to the frame of the opposing structure. Causes relative displacement to. Since both the horizontal members and the vertical members of the reinforcing structure 104 are rigidly joined to each other, at this time, the ring spring mounting body 107 is reinforced with respect to the fixing plate holding frame 108 installed in the frame of the building. Structure 10
4 is a floating plate holding frame 111 connected to the elastic connecting portion 112.
Causes relative displacement, and the ring spring block 76 is compressed. As in the case of the ring spring mounting body 7 of the first embodiment, the compression force acts on the ring spring block 76 regardless of which side of the construction frame is deformed. In the case of the present embodiment, since the relative displacement in the ring spring mounting body 107 becomes large,
The number of ring spring blocks to be mounted can be reduced. In this embodiment, a ring spring mounting body 107 having a short length in which two ring spring blocks 76 are arranged in parallel is used in consideration of convenience of installation.

Each of the first to fourth embodiments described above has the following features. For example, Examples 1 and 2 can be carried out in both a newly built structure and an existing structure as long as there is a place where the device can be installed indoors. However, the place where it is installed is limited as is the case with the provision of braces. In the case of Examples 3 and 4, the reinforcement of the existing building is mainly targeted, and although there are problems with the appearance and the like, the feature is that most of the mounting work can be done from the outside.

The ring spring 31 has a large energy storage rate per unit volume and is suitable for supporting a large load. If the deformation is within the range of the allowable deformation amount, the deformation amount is proportional to the compressive force, and if the load is removed, the original shape is restored. Moreover,
Along with the expansion and contraction, friction occurs between the outer ring 29 and the inner ring 30, and vibration energy can be absorbed. Further, the ring spring 31 has been used for a long time as a shock absorber for a barrel of a cannon and a shock absorber for a vehicle connecting portion, and its performance stability has been sufficiently verified. The manufacturing cost of the device including the ring spring 31 is also expected to be considerably reduced by automating the manufacturing and mass production. The feature of the device of the present invention using the ring spring 31 is that the spring constants of the ring spring mounting bodies 7, 67, 107 can be adjusted to facilitate the reinforcement according to each building. In order to increase the resistance of the structure and to make the structure tough, the reinforcing structures 4, 44, 64, 104 cooperate with the structure of the structure to resist external forces and The skeleton must be able to maintain its resistance after it surrenders. If the ring spring mounts 7, 67,
If the reinforcing structures 4, 44, 64, 104 having no 107 are directly attached to the frame of the building, the rigidity of the frame to which the reinforcing structure is attached is increased, so that stress concentrates when receiving a load, Other skeletons of the structure play. As a result, the skeleton to which the reinforcing structures 4, 44, 64, 104 are attached yields first, and subsequently the other skeletons yield almost simultaneously. Ring spring mounts 7, 67, 1
The role of 07 is to prevent the stress concentration on the frame to which the reinforcing structures 4, 44, 64, 104 are attached and maintain its strength,
Reinforcement structure 4, even after the structure is no longer resistant
44, 64, 104 is to preserve the resistance.

From the above, the present invention is to solve the problem "i), from medium to small earthquakes to large earthquakes, in cooperation with the skeleton of a building to resist seismic force, and also to prevent vibration due to earthquake or wind. In contrast, it has the ability to absorb vibration energy, ii) it does not require equipment replacement and restoration work, and maintenance is easy, and iii) installation cost is economically acceptable. The equipment has stable performance and can be implemented at the current state of the art. "
