  In the techniques disclosed in Patent Documents 1 to 3 described above, the restraint member into which the core member is inserted is inserted into the steel pipe forming the outer shape of the restraint member. The space is left filled with concrete or mortar, and the restraint member of the technique disclosed in Patent Document 4 is formed only with an insertion portion for allowing the core member to pass therethrough. Yes.

  In order to install a vibration damping device configured by inserting a core member inside the restraining member in a structure such as a high-rise building, considering the workability, the weight of the entire vibration damping device is reduced, It is required that the handling work and installation work can be easily performed.

  An object of the present invention is to provide a vibration damping device and a method for manufacturing and installing the same, which can reduce the overall weight and can easily perform the handling operation and the installation operation.

  The vibration damping device according to the present invention is disposed between two constituent members constituting the structure, and one end portion in the length direction is coupled to one of the two constituent members. In addition, the other end portion in the length direction is connected to the other constituent member of the two constituent members, and the outer periphery of the core member is connected to the length direction of the core member. The core member is covered in the length direction, and the core member is inserted into the core member so as to be movable in the length direction. When a compressive force is applied to the core member, the core member is And a restraining member for restraining the member from being deformed in a direction that forms an angle with the length direction of the member, for inserting the core member into the restraining member. An insertion part that is formed through and formed separately from this insertion part. And it is characterized in that it is provided with spaces section.

  In this vibration damping device, an insertion portion formed so as to penetrate the core member and a space portion formed separately from the insertion portion are provided inside the constraint member. The weight is reduced by the amount of space, so the weight of the entire damping device is also reduced, so that handling work of the restraining member and damping device, installation work of the damping device, etc. can be performed easily. become.

  In the present invention described above, the two constituent members constituting the structure may be columns and beams that are structural materials of the structure, or gusset plates that are attached to these columns and beams and join the columns and beams. A bracket including

  Further, if the insertion part for inserting the core member and the space part formed separately from the insertion part are provided inside the restraining member, the size and length of the space part can be arbitrarily set. Can be set to That is, the space portion may have a short dimension in which a plurality or a plurality of space portions are provided in the length direction of the restraining member, or the space portion has a long dimension having a length extending in the length direction of the restraining member. It may be a thing. If the space portion is the latter, the weight of the restraining member can be further reduced.

  When the space portion has a length that extends in the length direction of the restraining member, the space portion may have a length that extends over the entire length of the restraining member. Such a restraining member can be manufactured by, for example, an extrusion molding method or a pultrusion molding method of aluminum or an aluminum alloy. In addition, including the case where the space portion does not reach both ends in the length direction of the restraining member, the restraining member can be manufactured by a casting method including an aluminum die casting method. May be steel.

  Further, the constraining member may have a cross-sectional shape orthogonal to the length direction of the constraining member having a closed cross-sectional shape or an open cross-sectional shape.

  And when making this cross-sectional shape into a closed cross-sectional shape, the location of the closed cross-sectional shape in which multiple space parts are provided may exist in a restraint member.

  Further, the closed cross-sectional shape may be any shape such as, for example, a square shape or a substantially square shape, a hexagonal shape or a substantially hexagonal shape, an octagonal shape or a substantially octagonal shape, a round shape or a substantially round shape, an elliptical shape or a substantially elliptical shape. .

  In addition, when the cross-sectional shape orthogonal to the length direction of the restraining member is an open cross-sectional shape, the space provided inside the restraining member may be communicated with the outside through the opening of the open cross-sectional shape.

  Furthermore, a rib portion for reinforcement may be installed in the space portion for reducing the weight of the restraining member. According to this, even if the restraint member is lightened by the space portion, the overall strength of the restraint member is reduced by the rib portion, and the core member is buckled when the compressive force is applied. It can be made large enough to prevent deformation in the forming direction.

  In the present invention, the number of core members may be one, but the number of core members may be at least two, and these core members may be arranged parallel to each other and inserted into the restraining member. According to this, even if the vibration energy of the structure is large, the core member can be sufficiently absorbed by tensile plastic deformation or compression plastic deformation.

  When the number of core members is two, the two constituent members to which both ends of the core members in the length direction are coupled are brackets attached to the structural material of the structure, and these You may make it perform the coupling | bonding of the both ends of the length direction of two core members with respect to a bracket on both sides of the bracket between the ends of two core members.

  According to this, the number of the core members is one, the end surface in the length direction of the one core member is abutted against the end surface of the bracket, and the core member and the bracket are coupled by the plate-like connecting member, the bolt, or the like. As compared with the case, the advantage that the length of the coupling portion can be shortened can be obtained.

  Further, in the present invention, the core member may have a width dimension in a direction perpendicular to the length direction of the core member and the same dimension in the length direction of the core member. You may make it the shape where the center location of the length direction of the core member is constricted in the direction orthogonal to the length direction of a core member.

  According to this, when a tensile force or a compressive force due to the vibration energy of the structure is applied to the core member, a tensile plastic deformation or a compressive plastic deformation may be generated in a constricted portion in the center in the length direction of the core member. It is possible to prevent breakage or the like from occurring at the end in the length direction of the core member coupled to the structural member of the structure.

  Further, when the core member has a shape in which the central portion in the length direction of the core member is constricted in a direction perpendicular to the length direction of the core member, the length direction and the constriction direction of the core member A reinforcing member is disposed adjacent to the core member at a position in a direction orthogonal to both directions of the core member, and the constricted portion of the core member is pressed from both sides of the constricted direction into the portion corresponding to the constricted portion of the core member in the reinforcing member. A press-in portion may be provided.

  According to this, when an excessive compressive force acts on the core member, the core member bends and deforms in the constriction direction at the constricted portion. It can be prevented by the strength.

  Furthermore, when the number of core members is two and these core members have a shape in which the central portion in the length direction of these core members is constricted in a direction perpendicular to the length direction of the core members, A space member is arranged at a position between two core members that are positions in a direction orthogonal to both the length direction and the constriction direction of the two core members, and the two core members of the space member You may provide the pressing-in part for pressing down the constriction location of two core members from the constriction direction both sides in the location corresponding to a constriction location.

  According to this, the two core members are bent and deformed in the constriction direction in the constricted portions provided in these core members, and the pressing action of the pressing portion provided in the space member and the reinforcing member This can be prevented by the strength of the space member.

  Further, in the present invention, the aforementioned insertion portion provided inside the restraining member may be filled with mortar, and the core member may be disposed inside the mortar.

  According to this, since the periphery of the core member is covered with mortar, it is not necessary to form the insertion part inside the restraining member with a high-precision dimension that accurately corresponds to the dimension such as the thickness of the core member. As a result, the restraint member can be easily manufactured.

  The manufacturing and installation method of the vibration damping device according to the present invention is arranged between two constituent members constituting a structure, and one end portion in the length direction is disposed on one constituent member of the two constituent members. And the other end of the length direction is coupled to the other component of the two components, and the outer periphery of the core member is connected to the core member When the length direction is covered with the length direction, the core member is movably inserted in the length direction of the core member, and a compression force is applied to the core member. A restraining member for restraining deformation of the member in a direction that forms an angle with the length direction of the core member, and a method for manufacturing and installing the vibration damping device.

Inside, an insertion part for inserting the core member and a space part formed separately from the insertion part are provided over the entire length of the restraining member, and the material of the restraining member is more than steel or concrete. The restraint member is made of lightweight aluminum or aluminum alloy, and a space part separated from the insertion part for inserting the core member is provided over the entire length of the restraint member inside the restraint member. The weight of the vibration control device can be reduced, and the overall weight of the vibration control device can also be reduced. This makes it easy to handle restraint members and vibration control devices, and to install vibration control devices. It can be done.

  Further, by providing an insertion part for inserting the core member and a space part formed separately from the insertion part inside the restraining member, an extrusion molding method or a pultrusion molding method of aluminum or aluminum alloy is used. Easy to do.

  In the present invention described above, the material of the core member is arbitrarily set according to the damping performance required for the structure in which the vibration damping device according to the present invention is installed. Therefore, the core member has different yield strength. Therefore, it is manufactured using a material appropriately selected from various materials having different strengths at which tensile plastic deformation and compression plastic deformation occur.

  For this reason, in the present invention, as the material of the core member, a material having a high yield strength and a high strength at which tensile plastic deformation or compression plastic deformation is generated may be selected. Since it should also be called a seismic device, the damping device according to the present invention includes a device that is substantially a seismic device.

  In addition, the core member may have an elongated plate-like shape as a whole, or protrude in the thickness direction into another shape, for example, an elongated plate-like member.

EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated based on drawing. FIG. 1 shows a state where a vibration damping device 1 according to an embodiment of the present invention is installed in a high-rise building that is a structure. This building consists of pillars 2 and 3 made of H-shaped steel, etc., standing upright and spaced apart from each other, and I-shaped steel or H-shaped steel, etc. The beams 4 and 5 are constructed as structural materials. A gusset plate 6 is connected to the joint between the column 2 and the beam 4, and a gusset plate is joined to the joint between the column 3 and the beam 5. 7 is connected. These columns 2 and 3, beams 4 and 5, and gusset plates 6 and 7 are components constituting the building.

  Of these constituent members, the gusset plates 6 and 7 are also brackets provided in the building in order to bridge the vibration damping device 1 of the present embodiment between two locations of the building. Since the gusset plates 6 and 7 are arranged in the building with a difference in height, the vibration damping device 1 arranged inside the rectangular frame made up of the columns 2 and 3 and the beams 4 and 5 is arranged in the horizontal direction. It is installed in the building with an inclination angle with respect to.

  FIG. 2 shows only the vibration damping device 1. The vibration damping device 1 includes the core member 20 shown in FIG. 4 inside the restraining member 10 shown in FIG. 3 and the length of the core member 20. Both end portions 20A and 20B in the direction are exposed to the outside and are movably inserted. For this reason, the outer periphery of the core member 20 excluding both end portions 20 </ b> A and 20 </ b> B is covered with the restraining member 10. The restraining member 10 is obtained by cutting an extruded product or a pultruded product of aluminum or an aluminum alloy with a predetermined length. For this reason, the restraining member 10 is located at a position orthogonal to the length direction of the restraining member 10. The cross-sectional shape is the same shape and is continuous in the length direction of the restraining member 10, and this cross-sectional shape is continuous from one end in the length direction of the restraining member 10 to the other end. ing.

  FIG. 5 which is a sectional view taken along line S5-S5 in FIG. 2 and FIG. 6 which is a sectional view taken along line S6-S6 in FIG. 2 show the above-described sectional shape of the restraining member 10. Since the outer contour portion 11 forming the outer contour of the member 10 is composed of the upper side portion 11A, the lower side portion 11B, and the two side portions 11C and 11D which are the left and right side portions, It has a closed cross-sectional shape. Inside the restraining member 10, there is provided a vertically long core portion 12 having upper and lower ends connected to the upper side portion 11A and the lower side portion 11B. The core member 20 is movably inserted into the core portion 12. The insertion part 13 for doing is formed. As shown in FIG. 4, the core member 20 of the vibration damping device 1 according to the present embodiment has an elongated plate shape, and thus the insertion portion 13 has a vertically long slot shape. Moreover, since the two damping | damping apparatuses 1 are using the two core members 20, as shown in FIG.5 and FIG.6, two insertions are carried in the inside of the core part 12. As shown in FIG. The parts 13 are juxtaposed in the left-right direction, and a space between these insertion parts 13 is a partition wall 12A in the core part 12.

  Since the core part 12 is provided at a position equidistant from the two side parts 11C and 11D, both sides of the core part 12 are provided separately from the insertion part 13 inside the restraining member 10. The space portion 14 is formed. In each space part 14, a rib part 15 for reinforcement is installed, and in this embodiment, the core part 12 and the outer contour part 11 are connected to the rib part 15, and the outer contour is separated from the core part 12. A first rib portion 15A extending obliquely upward toward the portion 11, a second rib portion 15B that connects the core portion 12 and the outer contour portion 11 and extends horizontally from the core portion 12 toward the outer contour portion 11, and a core portion 12 and the outer contour portion 11, and there is a third rib portion 15 </ b> C extending obliquely downward from the core portion 12 toward the outer contour portion 11, and a total of six rib portions 15 are formed in the two space portions 14. The core portion 12 extends radially to the outer contour portion 11.

  The outer contour portion 11, the core portion 12, the insertion portion 13, the space portion 14, the first rib portion 15A, the second rib portion 15B, and the third rib portion 15C described above are one end in the length direction of the restraining member 10. From the first part to the other end part, the constraining member 10 is continuously formed over the entire length, and the insertion part 13 and the space part 14 are formed through. And the length direction of this restraining member 10 is also the length direction of the core member 20 shown in FIG. 4, and the length direction of the restraint member 10 and the length direction of the core member 20 correspond.

  Since the core member 20 shown in FIG. 4 is a member having an elongated plate shape as described above, the thickness dimension that can be inserted into the insertion portion 13 of the restraining member 10 is the core dimension. The length of the member 20 is continuous from one end 20A to the other end 20B in the length direction, and therefore the thickness of the core member 20 is constant over the entire length of the core member 20. is there. Further, at the center portion in the length direction of the core member 20, the dimension in the vertical direction perpendicular to the length direction is smaller than the width dimension of both end portions 20 </ b> A and 20 </ b> B in the length direction of the core member 20. The constricted portion 20 </ b> C is provided and has a length in the length direction of the core member 20, and both sides of the constricted portion 20 </ b> C which is also a constricted portion of the core member 20 are The width dimension enlarged portions 20D and 20E become gradually larger toward the both end portions 20A and 20B.

  In this way, the ends 20A and 20B of the core member 20 having a constricted overall shape are connected to connect the ends 20A and 20B to the gusset plates 6 and 7 shown in FIG. A plurality of bolt holes 21 are provided for inserting bolts 30A that are part of the tool 30 (see FIG. 7). Further, of the two end portions 20A and 20B, the end portion 20B coupled to the gusset plate 7 positioned lower than the gusset plate 6 by the coupling tool 30 is closer to the width dimension enlarged portion 20E than the bolt hole 21. In FIG. 7, a stop portion 22 is provided, and the stop portion 22 is attached to the core member 20 by welding as shown in FIG. 7, which is a sectional view taken along line S7-S7 of FIG. Therefore, the core member 20 protrudes in the thickness direction.

  In order to install the vibration damping device 1 in the building shown in FIG. 1, first, a restraint member 10 and two core members 20 that are components of the vibration damping device 1 are manufactured in a factory. The restraining member 10 is manufactured in a factory by cutting a molded product obtained by an extrusion molding method or a pultrusion molding method of aluminum or aluminum alloy into a predetermined length. Moreover, the operation | work which attaches the small piece member used as the stop part 22 to each core member 20 by welding is also performed in a factory.

  Thus, when the restraint member 10 is manufactured in the factory, the core portion 12, the insertion portion 13, the space portion 14, the first rib portion 15A, the second rib portion 15B, and the third rib portion 15C are contained inside the restraint member 10. The core portion 12, the insertion portion 13, the space portion 14, the first rib portion 15A, the second rib portion 15B, and the third rib portion 15C are continuous over the entire length of the restraining member 10. The insertion portion 13 and the space portion 14 are formed so as to penetrate therethrough, and the two space portions 14 provided on both sides of the core portion 12 are separated from the insertion portion 13 formed in the core portion 12. It has become a thing. And in the closed cross-sectional shape mentioned above in the arbitrary locations of the restraint member 10, the two space parts 14 exist.

  Moreover, when manufacturing the core member 20 in a factory, the material of the core member 20 is selected according to the damping performance calculated | required by the building in which the damping device 1 is installed. For example, if the material has a low yield strength, LYP225 or LYP100 is selected according to the JIS standard, and if the material has a higher yield strength, SM490 or SS400 is selected according to the JIS standard.

  Next, an operation of inserting the two core members 20 into the two insertion portions 13 of the restraining member 10 is performed, and this insertion operation is a stop provided on the two core members 20 as can be seen from FIG. The direction of the portion 22 is set to be opposite to each other, and each core member 20 is inserted into the insertion portion 13 from the end portion 20A where the stop portion 22 is not provided. Both end portions 20 </ b> A and 20 </ b> B are projected from both end surfaces in the length direction of the restraining member 10. In addition, before performing the operation | work which penetrates each core member 20 to the insertion part 13, the operation | work which attaches a low friction material to the surface of each core member 20 is performed, and, thereby, these core members 20 are inserted to the insertion part 13. It can be moved smoothly.

  The insertion work of the core member 20 to the insertion part 13 performed as described above may be performed at a factory or may be performed at a building site of a building where the vibration damping device 1 is installed.

  Next, in the building construction site of the building, the operation of arranging one end portion 20A in the length direction of the two core members 20 on both side surfaces in the thickness direction of the gusset plate 6 shown in FIGS. That is, the work of sandwiching the gusset plate 6 is performed between one end 20A in the length direction of the two core members 20, and the other end 20B in the length direction of the two core members 20 Thus, the operation of sandwiching the gusset plate 7 shown in FIGS. 1 and 7 is performed. Thereafter, the bolts 30A are inserted into the bolt holes 21 provided in the respective end portions 20A and 20B and the bolt holes 31 provided in the gusset plates 6 and 7 (see FIG. 7). By tightening the screwed nut 30B, the two end portions 20A and 20B in the longitudinal direction of the core member 20 are structural members of the building as described above with the coupler 30 including the bolt 30A and the nut 30B. The core member 20 is connected to gusset plates 6 and 7 which are also brackets for connecting the building structural material.

  The end portions 20A and 20B in the length direction of the core member 20 may be joined to the gusset plates 6 and 7 by welding instead of the bolts 30A and nuts 30B.

  Moreover, when the operation | work which couple | bonds the both ends 20A and 20B of the length direction of the core member 20 to the gusset plates 6 and 7 as mentioned above is carried out, the end 20A side of the core member 20 is made high, and the end 20B By making the side low, the entire vibration damping device 1 is inclined with respect to the horizontal direction. However, since the stop portion 22 is provided at the end portion 20 </ b> B, the restraining member 10 extends along the core member 20. Thus, the slide portion is prevented from being slid and dropped, and therefore, the operation of coupling the both end portions 20A and 20B of the core member 20 to the gusset plates 6 and 7 can be easily performed.

  After the vibration damping device 1 is installed in the building as shown in FIG. 1, when a lateral load F is applied to the building due to an earthquake or wind pressure, it consists of columns 2, 3 and beams 4, 5. When the square frame 20 is deformed, and the core member 20 that is stretched or compressed by the tensile force or compressive force caused by the lateral load F is plastically deformed beyond the yield point, the vibration energy of the building caused by the lateral load F is reduced by the core member. It is absorbed by the tensile plastic deformation and the compressive plastic deformation, which are 20 axial plastic deformations, whereby the shaking of the building is attenuated and suppressed. Further, the lateral load F causes an excessive compressive force to act on the core member 20, and the core member 20 is deformed in a direction that forms an angle with the length direction of the core member 20 by buckling or the like. In this case, since the core member 20 is movably inserted into the insertion portion 13 inside the restraining member 10, the deformation of the core member 20 is restrained by the restraining member 10, and the core member 20 is not deformed.

  According to the present embodiment described above, the restraint member 10 is provided with the space portion 14 formed separately from the insertion portion 13 through which the core member 20 is inserted. Since the weight of the restraining member 10 can be reduced by the amount, and the overall weight of the vibration damping device 1 is also reduced, the handling work of the restraining member 10 and the vibration damping device 1, the installation work of the vibration damping device 1, etc. Can be easily performed.

  Moreover, in this embodiment, the space part 14 has the length extended in the length direction of the restraint member 10, is formed over the full length of the restraint member 10, and the insertion part 13 is formed. Since the two space portions 14 are provided on both sides of the core portion 12 and the restraint member 10 is made of aluminum or aluminum alloy, the weight of the restraint member 10 is reduced. Thereby, the weight reduction of the entire weight of the vibration damping device 1 can be more effectively realized.

  Moreover, since the restraint member 10 is manufactured from the molded product obtained by the extrusion molding method or the pultrusion molding method of aluminum or aluminum alloy, the restraint member 10 in which the insertion portion 13 and the space portion 14 are provided can be easily provided. Can be manufactured.

  Further, even if the space portion 14 for reducing the weight is provided inside the restraining member 10, since the rib portion 15 for reinforcement is provided in the space portion 14, the overall strength of the restraining member 10 is increased. Is made large enough to prevent the core member 20 from buckling and deforming in a direction that forms an angle with the length direction of the core member 20 when a compressive force is applied. be able to.

  Further, there are two core members 20, and these core members 20 are arranged in parallel to each other and are inserted through two insertion portions 13 formed inside the restraining member 10, so that the vibration energy of the building is large. However, vibration energy can be sufficiently absorbed by the tensile plastic deformation and the compressive plastic deformation of the core member 20.

  Further, the end portions 20A and the end portions 20B of the two core members 20 sandwich the gusset plates 6 and 7 of the building, and the end portions 20A and the end portions 20B are the gusset plates 6 and 6, respectively. 7, since both ends 20 </ b> A and 20 </ b> B in the length direction of the core member 20 are connected to building components by being coupled with the coupler 30 by the bolt 30 </ b> A and the nut 30 </ b> B. The length of the coupling part for coupling the component member can be shortened.

  Specifically, in order to reduce the number of core members to one and transmit the vibration energy of the building to the core members in a predetermined manner, the end surface of the core member in the longitudinal direction is subjected to vibration energy. Abutting against the end face of the gusset plate to be transmitted, a plate-like connecting member is bridged between the core member and the gusset plate, and these are connected by a coupling device such as a bolt. According to this, the core member and the gusset In order to obtain a high bonding strength with the plate, the plate-like connecting member must have a long dimension with a large dimension in the longitudinal direction of the core member. For this reason, the core member and the gusset plate are coupled. For this reason, the length of the connecting portion is increased.

  On the other hand, in this embodiment, since the end portions 20A and the end portions 20B of the two core members 20 sandwich the gusset plates 6 and 7 of the building, the vibration energy of the building is transferred to the gusset plate. 6 and 7, and can be equally distributed to each core member 20, and the core member 20 and the gusset plates 6 and 7 can be coupled by the coupling tool 30 without using the plate-like connecting member described above. The length of the connecting portion can be shortened, and thereby the fitting of the connecting portion in the building can be made favorable.

  Furthermore, the overall shape of the core member 20 of the present embodiment is constricted in a direction perpendicular to the length direction of the core member by providing the constricted portion 20C at the central portion of the core member 20 in the length direction. Therefore, when a tensile force or a compressive force due to the vibration energy of the building is applied to the core member 20, a tensile plastic deformation or a compressive plastic deformation occurs in the constricted portion 20C having a small cross-sectional area. It is possible to prevent breakage or the like from occurring at both ends 20A and 20B in the length direction of the core member 20 which is a structural member of the building and is coupled to the gusset plates 6 and 7 which are also the brackets described above.

  FIG. 8 shows two vibration control systems in which the inclination directions with respect to the horizontal direction are opposite to each other inside the rectangular frame formed by the left and right columns 42 and 43 and the upper and lower beams 44 and 45, which are building structural materials. An embodiment in which the apparatus 1 is installed is shown. In this embodiment, the span between the left and right columns 42 and 43 is large, and one end 20A of each core member 20 in the two vibration damping devices 1 is coupled to the bracket 46 provided on the beam 44. The other end 20B of the core member 20 in one of the two damping devices 1 is coupled to a gusset plate 47 provided at the joint between the column 43 and the beam 45, The other end 20 </ b> B of the core member 20 in the other vibration damping device 1 is coupled to a gusset plate 48 provided at a joint portion between the column 42 and the beam 45. Also in this embodiment, the gusset plates 47 and 48 are brackets for connecting the vibration damping device 1 to the building, and the bracket 46 and the gusset plates 47 and 48 are provided with the columns 42 and 43 and the beams 44 and 45. Similarly, it is a structural member constituting a building.

  According to this embodiment, when a lateral load acts on the building, and a compressive force acts on the core member 20 of one of the two damping devices 1, the other damping device. When a tensile force acts on one core member 20 and the direction of the lateral load is reversed, a tensile force acts on the core member 20 of one vibration damping device 1 and acts on the core member 20 of the other vibration damping device 1. Since the compressive force acts, the vibration energy is effectively absorbed by the two damping devices 1, and the shaking of the building can be more effectively suppressed.

  In this embodiment, a stud may be erected at the bracket 46 or may not be erected.

  FIG. 9 shows a vibration damping device 51 according to another embodiment. This vibration damping device 51 includes a restraining member 60 shown in FIG. 10, a core member 70 shown in FIG. 11, and a space member 80 shown in FIG. Since the core member 70 of FIG. 11 is a member having an elongated plate shape as a whole in the same manner as the core member 20 of the embodiment shown in FIG. 4, the same thickness dimension is used for the core member 70. Therefore, the thickness dimension of the core member 70 is constant over the entire length of the core member 70. Further, at the center portion in the length direction of the core member 70, the vertical width dimension perpendicular to the length direction is smaller than the width dimensions of both end portions 70A and 70B in the length direction of the core member 70. The constricted portion 70C is provided, and both sides of the constricted portion 70C having a length in the length direction of the core member 70 have width dimension enlarged portions 70D, the width dimension of which gradually increases toward both end portions 70A, 70B. 70E.

  Further, the end portions 70A and 70B of the core member 70 having a constricted overall shape as described above are coupled to the gusset plates 6 and 7 shown in FIG. A plurality of bolt holes 71 for inserting the bolts 30A that are part of the coupling tool 30 are provided, and of the both end portions 70A and 70B, the end portions 70B are wider than the bolt holes 71. A stop portion 72 provided by attaching a small piece-like member to the core member 70 by welding is provided at a location close to the dimension enlarged portion 70E.

  The space member 80 in FIG. 12 is also a member having an elongated plate shape as a whole, but the space member 80 is orthogonal to the length direction at the center in the length direction of the space member 80. A constricted portion having a small size in the width direction is not provided. For this reason, the space member 80 has the same upper and lower width dimensions and is continuous over the entire length of the space member 80, and is orthogonal to the length direction and the width direction of the space member 80. The thickness dimension which is the dimension in the direction is also the same dimension and is continuous over the entire length of the space member 80.

  As can be seen from a comparison between FIG. 11 and FIG. 12, the total length of the space member 80 is shorter than the total length of the core member 70, and the length dimension of the space member 80 varies from the total length of the core member 70 to both ends of the core member 70. It is a dimension obtained by subtracting the length dimensions of 70A and 70B. Further, the upper and lower width dimensions of the space member 80 are the same as or substantially the same as the maximum width dimension of the core member 70.

  14 is a cross-sectional view taken along line S14-S14 in FIG. 9, and FIG. 15 is a cross-sectional view taken along line S15-S15 in FIG. As shown in FIGS. 14 and 15, the damping device 51 according to this embodiment also uses two core members 70, and a space member 80 is arranged between these core members 70. Yes. For this reason, in this vibration damping device 51, the space member 80 is disposed adjacent to the core member 70 at a position in a direction orthogonal to both the length direction and the constriction direction of the core member 70. The position where the space member 80 is disposed with respect to the member 70 is a position between the two core members 70, and this position is the length of the core member 70 for each of the two core members 70. It is a position in a direction perpendicular to both the direction and the constriction direction.

  In addition, when arranging the space member 80 between the two core members 70 and combining the core member 70 and the space member 80, as can be seen from FIG. 16 which is a cross-sectional view taken along S16-S16 in FIG. The direction of the stop portion 72 provided on each core member 70 is opposite to each other, and both end portions 70A and 70B in the length direction of each core member 70 are both ends in the length direction of the space member 80. Let it be in a state of protruding from the surface.

  The state when the two core members 70 and the space member 80 are combined in this manner is shown in FIG. The space member 80 has a pressing portion 81 for pressing the constricted portion 70C from both the upper and lower sides of the constricted portion 70C at the portion corresponding to the constricted portion 70C formed in the core member 70. Is provided. As shown in FIG. 15, the pressing portion 81 according to this embodiment is configured by attaching a pressing member 83 to a space member 80 with a coupling member 82 using bolts 82 </ b> A and nuts 82 </ b> B. Are provided on both surfaces of the space member 80 in the thickness direction, and the constricted portions 70C of the two core members 70 are provided in the space member 80 disposed between the core members 70. The pressing portion 81 is pressed from both the upper and lower sides.

  The space member 80 provided with such a pressing-in portion 81 resists the core member 70 from being bent and deformed in the vertical direction, as will be described later, and reinforces the strength of the core member 70. It is a reinforcing member.

  Similarly to the restraining member 10 in FIG. 3, the restraining member 60 in FIG. 10 is obtained by cutting an extruded product or a pultruded product of aluminum or an aluminum alloy with a predetermined length. The cross-sectional shape at a location orthogonal to the length direction of the restraining member 60 is the same shape and is continuous in the length direction of the restraining member 60. This cross-sectional shape is one of the length directions of the restraining member 60. From one end to the other end.

  As shown in FIGS. 14 and 15, this cross-sectional shape is an octagonal closed cross-sectional shape. Therefore, the outer contour portion 61 of the restraining member 60 includes an upper side portion 61 </ b> A, a lower side portion 61 </ b> B, Two side parts 61C and 61D, which are side parts, and four oblique side parts 61E, 61F, 61G, and 61H provided obliquely between the upper side part 61A and the lower side part 61B and the side parts 61C and 61D, Consists of. In addition, a core portion 62 is formed inside the restraining member 60, and two core members 70 and one space member 80 that are combined with each other in the thickness direction in the core portion 62. One insertion part 63 is provided for allowing the two to pass through. Both sides of the core part 62 whose upper and lower ends are connected to the upper side part 61A and the lower side part 61B are space parts 64 separated from the insertion part 63, and the insertion part 63 and the space part 64 are provided on the core part 62. It is isolated by a partition wall 66 that is a part, and is formed through the entire length of the restraining member 60.

  The insertion portion 63 includes a narrow insertion portion 63A at the upper and lower central portions having a narrow width corresponding to the total thickness of the two core members 70 and one space member 80, and a bolt of the coupler 82. 82A and nut 82B are also made up of wide insertion portions 63B and 63C at both upper and lower end portions which are wide in order to be movable. For this reason, the partition wall 66 that separates the insertion portion 63 from the space portion 64 includes an upper and lower central portion 66A corresponding to the narrow insertion portion 63A and upper and lower end portions 66B corresponding to the wide insertion portions 63B and 63C. , 66C.

  Inside the restraining member 60, horizontal rib portions 65 that connect the outer contour portion 61 and the core portion 62 are formed on both sides of the core portion 62. In the present embodiment, the upper and lower rib portions 65 are the rib portions 65. 65A and 65B are provided. For this reason, also in this embodiment, these rib portions 65A and 65B are installed in the space portion 64 provided inside the restraining member 60.

  Further, in the present embodiment, the upper and lower central portion 66A of the partition wall 66 is provided with an uneven portion 67 in which small unevenness is continuous in the vertical direction on the surface of the insertion portion 63 facing the narrow insertion portion 63A. Yes.

  The restraining member 60 of the vibration damping device 51 according to the above embodiment is also manufactured by cutting a molded product obtained by an extrusion molding method or a pultrusion molding method of aluminum or an aluminum alloy at a predetermined length in a factory. The operation of attaching a small piece member serving as the stop portion 72 to each core member 70 by welding is also performed at the factory.

  When performing the operation of inserting the two core members 20 and the one space member 80 into the insertion portion 63 of the restraining member 60, the space member is interposed between the two core members 70 as described in FIG. 80, the core member 70 and the space member 80 are combined, and then the core member 70 and the space member 80 from the end portion 70A where the stop portion 72 is not provided among the both end portions 70A and 70B of the core member 70. Is inserted into the insertion portion 63, and both end portions 70 </ b> A and 70 </ b> B in the length direction of the respective core members 70 are protruded from both end surfaces in the length direction of the restraining member 60. The state at this time is shown in FIG. Even in this embodiment, before performing the operation of inserting the core member 70 and the space member 80 through the insertion portion 63, the operation of attaching the low friction material to the surface of the core member 20 is performed. These core members 70 can be smoothly moved with respect to the insertion portion 63.

  Next, in order to install the vibration damping device 51 according to this embodiment in a building, when the vibration damping device 51 is installed between the gusset plates 6 and 7 shown in FIG. As in FIG. 1, one end portion 70A in the length direction of the two core members 70 is arranged on both side surfaces in the thickness direction of the gusset plate 6 as shown in FIG. The gusset plate 6 is sandwiched between the end portions 70A, and the gusset plate 7 is sandwiched between the other end portions 70B in the length direction of the two core members 70, and the bolts provided on the respective end portions 70A and 70B The bolt 30A is inserted into the hole 71 and the bolt hole 31 provided in the gusset plates 6 and 7, and the nut 30B screwed to the bolt 30A is tightened. Both ends 0A, 70B to bind to gusset plates 6,7.

  Also in this embodiment, the end portions 70A and 70B in the length direction of the core member 70 may be joined to the gusset plates 6 and 7 by welding instead of the bolts 30A and nuts 30B.

  Also in this embodiment, when a lateral load in the left-right direction is applied to the building due to an earthquake or wind pressure, the core member 70 that has been deformed or compressed by a tensile force or a compressive force due to the lateral load is plastic beyond the yield point. By the deformation, the vibration energy of the building due to the lateral load is absorbed by the tensile plastic deformation and the compressive plastic deformation of the core member 70, and the shaking of the building is attenuated and suppressed.

  Also in this embodiment, a space portion 64 is provided inside the restraining member 60, and this space portion 64 has a length extending in the length direction of the restraining member 60. Since the rib portion 65 is installed, the same operational effects as those of the vibration damping device 1 of the above-described embodiment can be obtained, and the number of the core members 70 is two. The overall shape is constricted by the constricted portion 70C, and the end portions 70A of the two core members 70 and the end portions 70B are coupled by the coupling tool 30 with the gusset plates 6 and 7 interposed therebetween. Therefore, also in these respects, the same operational effects as those of the vibration damping device 1 of the above-described embodiment can be obtained.

  In this embodiment, as described above, the upper and lower central portion 66A of the partition wall 66 is provided with the uneven portion 67 on the surface facing the narrow insertion portion 63A of the insertion portion 63. In order to reduce the friction with the core member 70, the friction when the core member 70 moves through the insertion portion 63 of the restraining member 60 due to the lateral load can be reduced, and the core member 70 can be moved smoothly.

  Furthermore, according to this embodiment, even if the constricted portions 70 </ b> C are formed in each of the two core members 70, these constricted portions 70 </ b> C are connected to the space member 80 disposed between the core members 70. Since the pressing member 81 is pressed from both the upper and lower sides, when a large compressive force is applied to the core member 70 by the lateral load described above, the core member 70 is moved vertically in the constricted portion 70C. The pressing portion 81 can prevent the bending deformation. In other words, the space member 80 to which the pressing-in portion 81 is attached becomes a member that resists the core member 70 from being bent and deformed in the vertical direction at the constricted portion 70C that is the constricted portion of the core member 70, Since the core member 70 can be prevented from being bent and deformed in the vertical direction by the strength of the space member 80, the space member 80 is a reinforcing member that reinforces the strength of the core member 70 with respect to the vertical deformation. As a result, tensile plastic deformation and compression plastic deformation can be more reliably generated in the core member 70 in order to more effectively realize absorption of vibration energy of the building and attenuation and suppression of vibration of the building.

  In addition, as shown in FIG. 8, two damping devices 51 of this embodiment can be installed inside the rectangular frame of the building with the inclination directions with respect to the horizontal direction being opposite to each other.

In addition, two partition walls 102 </ b> A and 102 </ b> B linearly extending in the vertical direction are arranged in parallel inside the restraining member 100 at intervals, and these partition walls forming the core portion 102 of the restraining member 100. Between 102A and 102B is an insertion portion 103 for inserting two core members 90 side by side. Both sides of the core portion 102 are space portions 104 separated from the insertion portion 103, and the insertion portion 103 and the space portion 104 are isolated by the partition walls 102 </ b> A and 102 </ b> B of the core portion 102 and the entire length of the restraining member 100. It is formed through.

  Inside the restraining member 100, horizontal rib portions 105 that connect the outer contour portion 101 and the core portion 102 are formed on both sides of the core portion 102. In this embodiment, the restraining member 100 is formed over the entire length of the restraining member 100. As the rib portion 105, three upper and lower rib portions 105A, 105B, and 105C are provided. For this reason, also in this embodiment, these rib portions 105A, 105B, and 105C are installed in the space portion 104 formed separately from the insertion portion 103 inside the restraining member 100.

It has been broken. In order to arrange the two core members 90 in the insertion portion 103 filled with the mortar 106, first, the core member 90 having a low friction material attached to the surface is inserted into the insertion portion 103. Then, an operation of filling the insertion portion 103 with the mortar 106 is performed. The interval between the two core members 90 corresponds to the thickness of the gusset plates 6 and 7 shown in FIG. 1, and these end members protrude from both ends in the length direction of the restraining member 100 with the end members crowned. Both end portions of the core member 90 in the length direction are coupled by a bolt or nut coupler or welding with the gusset plates 6 and 7 sandwiched in the same manner as in the above-described embodiment.

  Also in this embodiment, when a lateral load in the left-right direction is applied to the building due to an earthquake or wind pressure, the core member 90 that is stretched or compressed by the tensile force or compressive force due to the lateral load is plastically deformed beyond the yield point. In other words, the vibration energy of the building due to the lateral load is absorbed by the tensile plastic deformation and the compressive plastic deformation of the core member 90, so that the shaking of the building is attenuated and suppressed.

  In this embodiment as well, the space 104 is provided separately from the insertion portion 103 inside the restraining member 100, and the space portion 104 has a length extending in the length direction of the restraining member 100. Moreover, since the rib part 105 is constructed in the space part 104, the same effect as the damping device 1 of embodiment mentioned above can be acquired.
