Description

  The present invention relates to a joining member, and more particularly to a joining member that integrates a building and an earthquake-resistant reinforcing member attached to the outside of the building.

  There is a method of installing a seismic reinforcement body outside the building as a seismic reinforcement method for performing seismic reinforcement on an existing building. For example, Patent Document 1 discloses a construction in which a new concrete structure is constructed in contact with the surface of an existing concrete structure. A fixing member for increasing the fixation of the concrete is disposed on the boundary surface between the existing concrete structure and the newly-built concrete structure.

JP 2010-59717 A

  The seismic reinforcement method described in Patent Document 1 is a so-called wet reinforcement method using a new concrete structure, and it is necessary to place concrete on site. For this reason, there exists a problem that the construction property of an earthquake-proof reinforcement construction is bad. Moreover, since workability is bad, there exists a problem that construction cost increases.

  In addition, in the seismic reinforcement method described in Patent Document 1, it is necessary to bring a new concrete structure into close contact with an existing concrete structure. For this reason, it is necessary to expose at least the entire outer surface of the existing concrete structure, which also increases the construction cost.

  The problem to be solved by the present invention is to provide a joint member that integrates a building and a seismic reinforcement member that is attached to the outside of the building, which enables excellent seismic reinforcement workability and enables seismic reinforcement with reduced construction costs. It is to provide.

  In order to solve the above problems, a joining member according to the present invention is a joining member that integrates a building and a seismic reinforcing member attached to the outside of the building, and is formed of a steel shaft and a base of the shaft. The gist is that a flange provided, a cotter provided so as to protrude in a direction perpendicular to the surface from the surface of the flange, and an anchor for fixing the peripheral edge of the flange are provided. is there.

  Moreover, the other joining member which concerns on this invention is a joining member which integrates a building and the seismic reinforcement member attached to the outer side of a building, Comprising: The shaft body which consists of steel materials, and the base of the said shaft body were provided. The gist of the invention is that a flange and an anchor for fixing the peripheral edge of the flange are provided.

  At this time, the shaft body is preferably provided with a length adjusting mechanism.

  And the fixing bolt which fixes the said earthquake-proof reinforcement member to the front-end | tip part of the said shaft body, and the presser washer of the said fixing bolt may be provided in the front-end | tip part of the said shaft body. In this case, it is preferable that the holding washer is provided with a long hole serving as an insertion hole through which the fixing bolt is inserted.

  And the joining member which concerns on this invention may attach the said earthquake-proof reinforcement member away from the housing outer surface of a building. Further, the steel reinforcing member as the seismic reinforcing member may be attached separately from the outer surface of the building frame.

  The joint member according to the present invention integrally integrates the building and the earthquake-resistant reinforcement member attached to the outside of the building by fixing the flange peripheral portion of the shaft body base to the building frame with an anchor and attaching the earthquake-resistant reinforcement member to the shaft body tip. Therefore, according to this joining member, it is possible to attach this to the outside of the building using a steel reinforcing member as the seismic reinforcing member, so that the concrete or mortar is not wet using concrete or mortar. Dry seismic reinforcement that is not used can be performed. That is, since it is not necessary to place concrete or mortar on site, the workability of the seismic reinforcement work is excellent. Moreover, since it is excellent in workability, construction cost can be suppressed.

  Moreover, according to the joining member which concerns on this invention, since an earthquake-proof reinforcement member can be separated and attached from the outer surface of a building frame, it is sufficient to expose only the part which attaches a joining member among the outer surfaces of a building frame. Thereby, construction cost can be held down.

  And in the joining member which concerns on this invention, if the length adjustment mechanism is provided in the shaft body, even if the position of the outer surface of a building frame does not align, the length of a shaft body will be changed and an earthquake-proof reinforcement member will be attached. By making the position of the tip of the shaft body the same, the seismic reinforcement member can be attached. That is, there is an advantage that the application range is wide because the installation place of the seismic reinforcement member is not selected.

  Further, in the joining member according to the present invention, a fixing bolt for fixing the seismic reinforcing member to the tip of the shaft body and a pressing washer for the fixing bolt are provided at the shaft tip, and the fixing bolt is provided on the pressing washer. If a long hole serving as an insertion hole to be inserted is provided, if a construction error occurs between the installation position of the earthquake-proof reinforcement member and the attachment position of the joining member, the construction error can be absorbed and alignment can be performed. .

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic diagram showing a partial cross section of a joining member according to a first embodiment of the present invention. 2-4 is the figure which showed the example of application to the building of the joining member which concerns on this invention. FIG. 5 is a schematic view of the joining member according to the present invention as viewed from the front end side of the shaft body, with the seismic reinforcement member attached to the front end portion of the shaft body.

  As shown in FIG. 1, the shaft body 12 of the joining member 10 is made of a steel material formed into a columnar shape. Although it does not specifically limit as steel materials, SS400, SN400, SN490, SM400, SM490, STKM13A, S45C etc. are mentioned. The size of the shaft body 12 is not particularly limited, but those having an outer diameter of 50 to 300 mm and an axial length of 20 to 500 mm are preferably used.

  A flange 14 is provided integrally with the shaft body 12 at the base of the shaft body 12. A cotter 16 is provided integrally with the flange 14 at the center position in the plane of the flange 14 so as to protrude from the plane in a direction perpendicular to the plane. A through hole 14 a that penetrates in the thickness direction of the flange 14 is formed at the peripheral edge of the flange 14 so that the anchor 18 can be inserted. A female screw hole 20 is formed in the central position of the tip of the shaft body 12 along the axial direction of the shaft body 12 so that it can be screwed into the fixing bolt 22. The fixing bolt 22 is screwed into the female screw hole 20 of the shaft body 12 with the presser washers 24 and 26 interposed therebetween. The presser washers 24 and 26 are formed of a set of two sheets (small-diameter presser washer 26 and large-diameter presser washer 24) having different diameters.

  Therefore, the joining member 10 includes a shaft 12, a flange 14, a cotter 16, an anchor 18, a fixing bolt 22, and presser washers 24 and 26.

  As shown in FIG. 2, the joining member 10 is attached to the outer surface of each of the column 1 and the beam 2 (building frame) of the column-beam frame composed of the column 1 and the beam 2 of the building. Specifically, in FIG. 2, eight joining members 10 are attached to the outer surfaces of the upper beam 2a and the lower beam 2b of the column beam frame, respectively, and two members are respectively attached to the outer surfaces of the left column 1a and the right column 1b of the column beam frame. A joining member 10 is attached. An H-shaped steel 3 is arranged in a frame shape on the outer surface of the column beam frame so as to connect between a plurality of joining members 10 arranged on the outer surface of the column beam frame. 4 is attached to the outside of the building by the joining member 10.

  As shown in FIG. 3, the joining member 10 is addressed so that the back surface of the flange 14 at the base of the shaft body 12 is in contact with the outer surface of the building frame (the upper beam 2 a and the lower beam 2 b in FIG. 3). Therefore, the shaft body 12 is disposed so as to extend outward from the outer surfaces of the building housings 2a and 2b. In this state, the anchors 18 are inserted into the through holes 14a on the peripheral edge of the flange 14, and the inserted anchors 18 are driven into the building housings 2a and 2b from the outer surfaces of the building housings 2a and 2b. It is fixed to the building frames 2a and 2b.

  As shown in FIG. 1, a fitting recess 5 a into which the cotter 16 of the joining member 10 is fitted is formed at a position where the joining member 10 on the outer surface (indicated by the dotted line 5) of the building frame is fixed. When the cotter 16 of the joining member 10 is fitted into the fitting recess 5a, the back surface of the flange 14 contacts the outer surface of the building frame.

  As shown in FIG. 1, the web surface 3 a of the H-shaped steel 3 has a circular hole 3 b having an inner diameter that is larger than the outer diameter of the small presser washer 26 and smaller than the outer diameter of the large presser washer 24. 3a is formed through in the thickness direction. The small-diameter press washer 26 is disposed in the circular hole 3b of the web surface 3a, and the large-diameter press washer 24 is disposed outside the web surface 3a coaxially with the small-diameter press washer 26. The fixing bolt 22 is inserted from the outside of the large-diameter press washer 24 into the insertion hole 24a of the large-diameter press washer 24 and the insertion hole 26a of the small-diameter press washer 26. The shaft body 12 is screwed into the female screw hole 20 at the tip portion. In this way, the H-shaped steel 3 is fastened to the tip end portion of the shaft body 12 of the joining member 10.

  In order to efficiently exhibit the performance of the seismic reinforcing member 4 attached to the outside of the building via the joining member 10, it is necessary to efficiently and sufficiently transmit the force borne by the seismic reinforcing member 4 during an earthquake or the like. . The joining member 10 serves as a stress transmission member that transmits stress between the building and the seismic reinforcement member 4. The stress to be transmitted is bending stress, shear stress, and tensile stress. Bending stress can be transmitted by the flange 14 and the anchor 18 of the joining member 10. Further, the shear stress can be transmitted by the cotter 16 of the joining member 10. Furthermore, the anchor 18 of the joining member 10 can resist tensile stress. As described above, the joining member 10 can efficiently and sufficiently transmit the force borne by the seismic reinforcing member 4 during an earthquake or the like. The bending resistance can be adjusted by the outer diameter of the flange 14, the number of anchors 18, and the like. The shear resistance can be adjusted by the height of the protrusion of the cotter 16 and the size of the outer diameter of the cotter 16. The tensile resistance can be adjusted by the number or position of the anchors 18.

  As shown in FIG. 4, the position of the outer surface of the building frame may not be aligned so that the position of the outer surface of the pillar 1 (1a) and the position of the outer surface of the beam 2 (2a) are not aligned. In this case, the joining members 10 in which the length of the shaft body 12 is changed may be combined. That is, since the position of the outer surface of the column 1 (1a) is outside the position of the outer surface of the beam 2 (2a), the connecting member 10 (10a) attached to the outer surface of the column 1 (1a) A member having a shaft 12 shorter than the joining member 10 (10b) attached to the outer surface 2 (2a) is used. By using the joining members 10a and 10b having different lengths of the shaft body 12 in combination, the position of the distal end portion of the shaft body 12 to which the H-section steel 3 of the seismic reinforcement member 4 is attached can be made the same.

  As shown in FIG. 5, in the joining member 10, when the insertion holes 24 a and 26 a of the press washers 24 and 26 are long holes, the installation position of the H-shaped steel 3 and the attachment position of the joining member 10 are provided. There is an advantage that when the construction error occurs, the positioning can be performed by absorbing the construction error.

  The holding washer of the joining member 10 is composed of a combination of a small diameter pressing washer 26 and a large diameter pressing washer 24. The insertion holes 24a and 26a of any of the holding washers 24 and 26 have the same elongated hole. The presser washers 24 and 26 can be rotated 360 degrees in the in-plane direction of the presser washers 24 and 26 before the fixing bolt 22 is fastened, and the major axis direction of the long hole is set in any direction in the plane. it can. For this reason, when the installation position of the H-shaped steel 3 of the seismic reinforcement member 4 and the attachment position of the joining member 10 are displaced, the major axis direction of the long hole is aligned with the direction of the displacement, and the fixing bolt 22 By finely adjusting the position in the long axis direction of the long hole, the installation error can be absorbed and the installation position of the H-shaped steel 3 of the seismic reinforcement member 4 and the attachment position of the joining member 10 can be aligned.

  The joint member 10 is fixed to the outside of the building and the building by fixing the peripheral portion of the flange 14 at the base of the shaft body 12 to the building frame with the anchor 18 and attaching the seismic reinforcement member to the distal end portion of the shaft body 12. The member is integrated. According to this joining member 10, since this can be attached to the outside of a building using a steel reinforcing member such as a steel frame made of H-shaped steel as a seismic reinforcing member, it is not wet using concrete or mortar. Dry seismic reinforcement without using concrete or mortar can be performed. In this case, since it is not necessary to place concrete or mortar on site, the workability of the seismic reinforcement work is excellent. Moreover, since it is excellent in workability, construction cost can be suppressed. Moreover, according to the joining member 10, since an earthquake-proof reinforcement member can be attached apart from the outer surface of a building frame, it is only necessary to expose only a portion to which the joining member 10 is attached on the outer surface of the building frame. Thereby, construction cost can be held down.

  Next, a joining member according to another embodiment of the present invention will be described. 6-10 is the schematic diagram which showed the joining member which concerns on 2nd-6th embodiment of this invention in the partial cross section. In any of the joining members according to any of the embodiments, the shaft body is provided with a length adjusting mechanism. In addition, in the joining member which concerns on other embodiment, since it is the same as that of the joining member which concerns on 1st embodiment about the attachment method to the outer surface of a building frame, and the attachment method of a seismic reinforcement member (H-section steel), Description is omitted.

  As shown in FIG. 6, the shaft body 32 of the joining member 30 according to the second embodiment includes a cylindrical body 34 in which a steel material is formed into a cylindrical shape, and a bolt-type cotter 36 in which the steel material is formed in a columnar shape.

  A disk-shaped top plate 34a is welded to one end of the cylindrical body 34, and one end of the cylindrical body 34 is closed. A female screw hole 34b is formed in the central position of the top plate 34a along the axial direction of the shaft body 32 so that it can be screwed into the fixing bolt 22. On the inner peripheral surface of the other end of the cylindrical body 34, a female screw 34c into which the male screw 36a of the bolt type cotter 36 is screwed is formed.

  On the outer peripheral surface of the bolt type cotter 36, a male screw 36a to be screwed with the female screw 34c of the cylindrical body 34 is formed by screwing. A head 36b having an outer diameter larger than the nominal diameter of the male screw 36a is provided at one end of the bolt-type cotter 36.

  The flange 38 at the base of the shaft body 32 is separate from the bolt-type cotter 36 of the shaft body 32 and is made of a steel plate. A female screw hole 38a into which the male screw 36a of the bolt-type cotter 36 is screwed is formed at the central position in the surface of the flange 38 so as to penetrate in the thickness direction. A through hole 38 b through which the anchor 18 is inserted is formed in the peripheral portion of the flange 38 in the thickness direction of the flange 38.

  When the male screw 36a of the bolt-type cotter 36 is screwed into the female screw hole 38a of the flange 38 from the back side of the flange 38 to the base of the male screw 36a, the male screw 36a of the bolt-type cotter 36 is placed on the front side of the flange 38. The head 36b of the bolt-type cotter 36 protrudes on the back side of the flange 38. The head 36b becomes a cotter that projects in a direction perpendicular to the surface from the back surface of the flange 38 and exhibits shear resistance. Thus, the flange 38 and the bolt-type cotter 36 are integrated by screwing. For the purpose of preventing the screw from loosening, a cylindrical loosening prevention steel pipe 39 having an internal thread 39a formed on the inner peripheral surface is formed. It is used. A male screw 36a is screwed into the female screw 39a of the loosening prevention steel pipe 39 from the other end side of the bolt type cotter 36 to the base of the male screw 36a. The loosening prevention steel pipe 39 has a flange 38 sandwiched between the head 36b of the bolt-type cotter 36, thereby preventing the screws from loosening. In this way, the bolt type cotter 36 is fixed to the flange 38.

  The loosening prevention steel pipe 39 has a length shorter than the length of the male screw 36a of the bolt type cotter 36, and a male screw 36a is provided on the other end side of the male screw 36a of the bolt type cotter 36 into which the loosening prevention steel pipe 39 is screwed. Is exposed. Accordingly, the male screw 36 a on the other end side of the bolt-type cotter 36 is screwed with a female screw 34 c formed on the inner peripheral surface of the other end of the cylindrical body 34. Thereby, the shaft body 32 is completed.

  The length of the shaft body 32 can be changed by relatively rotating between the cylindrical body 34 and the bolt type cotter 36. That is, when the relative rotation is performed between them, the cylindrical body 34 moves away from or approaches the flange 38, and the length of the shaft body 32 changes.

  Thus, in the joining member 30, since the shaft body 32 is provided with the length adjusting mechanism, the length of the shaft body 32 is changed and the seismic reinforcing member can be used even when the position of the outer surface of the building frame is not aligned. The seismic reinforcement member can be attached by making the position of the tip of the shaft body 32 to be attached the same. That is, there is an advantage that the application range is wide because the installation place of the seismic reinforcement member is not selected.

  As shown in FIG. 7, the shaft body 42 of the joining member 40 according to the third embodiment includes a bolt-type steel body 44 made of a steel material and a cylindrical body 46 obtained by forming the steel material into a cylindrical shape. A male screw 44 a is formed on the outer peripheral surface of the bolt-type steel body 44 by screwing. At one end of the bolt-type steel body 44, a head 44b having an outer diameter larger than the nominal diameter of the male screw 44a is provided. Both ends of the cylindrical body 46 are opened, and female screws 46a and 46b are formed on the inner peripheral surfaces of both ends of the cylindrical body 46, respectively.

  The flange 48 at the base of the shaft body 42 is separate from the cylindrical body 46 of the shaft body 42 and is made of a steel plate. A through hole 48 c through which the anchor 18 is inserted is formed in the peripheral portion of the flange 48 in the thickness direction of the flange 48. A protrusion 48a protruding in the direction perpendicular to the surface from within the surface is provided integrally with the flange 48 as a cotter at the center of the surface on the back surface side of the flange 48. A male screw 48 b protruding in the direction perpendicular to the surface from within the surface is provided integrally with the flange 48 at the center position on the surface side of the flange 48.

  The female screw 46 a formed by screwing on the inner peripheral surface of one end of the cylindrical body 46 is screwed with the male screw 44 a of the bolt-type steel body 44. A female screw 46 b formed on the inner peripheral surface of the other end of the cylindrical body 46 is screwed with a male screw 48 b provided on the surface side of the flange 48. A male screw 48 b provided on the surface side of the flange 48 is screwed into the female screw 46 b at the other end of the cylindrical body 46 until the other end of the cylindrical body 46 contacts the surface of the flange 48. By tightening strongly between the female screw 46b of the cylindrical body 46 and the male screw 48b of the flange 48, loosening of the screw is prevented, and the cylindrical body 46 and the flange 48 are integrated by screwing.

  The length of the shaft body 42 can be changed by relatively rotating between the bolt-type steel body 44 and the cylindrical body 46. That is, when the relative rotation between these is performed, the bolt-type steel body 44 is separated from or approaches the cylindrical body 46, and the length of the shaft body 42 is changed.

  A female screw hole 44c is formed in the central position of the head portion 44b of the bolt-type steel body 44 along the axial direction so that it can be screwed into the fixing bolt 22. In the joining member 40 according to the third embodiment, the holding washer has a small diameter portion 49b corresponding to the small diameter holding washer 26 of the joining member 10 according to the first embodiment and the large diameter of the joining member 10 according to the first embodiment. The stepped washer 49 is formed so as to be integrated with a large diameter portion 49a corresponding to the presser washer 24. The small diameter portion 49 b of the stepped washer 49 is disposed in the circular hole 3 b of the web surface 3 a of the H-section steel 3, as with the small diameter presser washer 26. The large-diameter portion 49 a of the stepped washer 49 is disposed outside the web surface 3 a of the H-section steel 3, similarly to the large-diameter presser washer 24. The fixing bolt 22 is inserted into the insertion hole 49c of the stepped washer 49 from the outside of the large diameter portion 49a, and is screwed into the female screw hole 44c at the tip of the shaft body 42 with the stepped washer 49 interposed therebetween. Thus, the H-section steel 3 is fastened to the tip end portion of the shaft body 42 of the joining member 40. The insertion hole 49c of the stepped washer 49 may be a long hole like the joining member 10 according to the first embodiment.

  As shown in FIG. 8, the shaft body 52 of the joining member 50 according to the fourth embodiment includes a bolt-type steel body 54 made of a steel material and a cylindrical body 56 obtained by forming the steel material into a cylindrical shape. Compared with the joining member 40 according to the third embodiment, the joining member 50 according to the fourth embodiment is not provided with a male screw on the surface side of the flange 58 of the base portion of the shaft body 52, The other end is joined to the center of the surface of the flange 58 by welding and the cylindrical body 56 and the flange 58 are integrated, and the same configuration is adopted.

  As shown in FIG. 9, the shaft body 62 of the joining member 60 according to the fifth embodiment includes a bag-shaped steel body 64 made of a cap-shaped steel material in which one end of a cylinder is closed by a top plate 64 b and the other end is opened, It consists of the cylindrical body 66 which shape | molded steel materials cylindrically. A female screw 64 a is formed on the inner peripheral surface of the bag-type steel body 64 on the opening end side. On the outer peripheral surface on one end side of the cylindrical body 66, a male screw 66 a that is screwed with the female screw 64 a that is screwed on the inner peripheral surface on the opening end side of the bag-type steel body 64 is formed by screwing. The other end of the cylindrical body 66 is joined to an in-plane center position of the surface of the flange 68 by welding, so that the cylindrical body 66 and the flange 68 are integrated.

  The length of the shaft body 62 can be changed by relatively rotating between the bag-shaped steel body 64 and the cylindrical body 66. That is, when these are rotated relatively, the bag-shaped steel body 64 moves away from or approaches the cylindrical body 66, and the length of the shaft body 62 changes.

  Like the flange 58 of the joining member 50 according to the fourth embodiment, the flange 68 of the joining member 60 is made of a steel plate, and the in-plane center position on the back side of the flange 68 is from the in-plane to the surface. A protrusion 68a protruding in the vertical direction is provided integrally with the flange 68 as a cotter. Similar to the joining member 10 according to the first embodiment, the presser washer of the joining member 60 is composed of a set of two sheets having different diameters (a small-diameter presser washer 26 and a large-diameter presser washer 24).

  As shown in FIG. 10, the shaft body 72 of the joining member 70 according to the sixth embodiment includes a bag-type steel body 74 made of a cap-shaped steel material in which one end of a cylinder is closed by a top plate 74 b and the other end is opened, It consists of the cylindrical body 76 which shape | molded steel materials cylindrically.

  Compared with the joining member 60 according to the fifth embodiment, the joining member 70 according to the sixth embodiment has not only the outer peripheral surface on one end side of the cylindrical body 76 but also the outer peripheral surface on the other surface side with external threads 76a, 76b is threaded. In addition, an internal thread cylindrical portion 79 is erected and formed at an in-plane center position on the surface of the flange 78 so as to protrude from the in-plane direction in a direction perpendicular to the surface. A female screw 79 a is formed on the inner peripheral surface of the female screw cylindrical portion 79, and this female screw 79 a is screwed with a male screw 76 b formed on the outer peripheral surface on the other surface side of the cylindrical body 76.

  The length of the shaft body 72 can be changed by relatively rotating between the bag-shaped steel body 74 and the cylindrical body 76. That is, when these are relatively rotated, the bag-shaped steel body 74 moves away from or approaches the cylindrical body 76, and the length of the shaft body 72 changes. Further, the length of the shaft body 72 can be changed by relatively rotating between the cylindrical body 76 and the female screw cylindrical portion 79. That is, when these are relatively rotated, the cylindrical body 76 moves away from or approaches the flange 78, and the length of the shaft body 72 changes.

  As with the flange 58 of the joining member 50 according to the fourth embodiment, the flange 78 of the joining member 70 has a projection 78a that protrudes in the direction perpendicular to the surface from the in-plane at the center of the back side of the flange 58. Are provided integrally with the flange 78. The holding washer of the joining member 70 is composed of a stepped washer 49 as in the joining member 40 according to the third embodiment.

  As shown in FIG. 11, the joining member 80 according to the seventh embodiment has a cotter shape integrally provided with the flange 68 on the back surface side of the flange 68 compared to the joining member 60 according to the fifth embodiment. It is only different and it is the same as that of the joining member 60 which concerns on 5th embodiment about another structure. Parts having the same configuration are denoted by the same reference numerals, and description thereof is omitted.

  A ring-shaped protrusion 88 projecting in a ring shape in the direction perpendicular to the surface from the surface is integrated with the flange 68 as a cotter at the in-plane center position on the back surface side of the flange 68 of the joining member 80 according to the seventh embodiment. Is provided. By adopting such a configuration of the cotter, the amount of shaving of the outer surface (indicated by the dotted line 5) of the building frame performed to form the fitting recess 5a into which the ring-shaped protrusion 88 is fitted is reduced. Therefore, there exists an advantage that the insertion recessed part 5a is easy to form in the outer surface (it shows with the dotted line 5) of a building frame.

  As shown in FIG. 12, the joining member 90 according to the eighth embodiment is different from the joining member 60 according to the fifth embodiment in that no protrusion 68 a as a cotter is formed on the back surface side of the flange 68. The other configurations are the same as those of the joining member 60 according to the fifth embodiment. Parts having the same configuration are denoted by the same reference numerals, and description thereof is omitted.

  As for the joining member 90 which concerns on 8th embodiment, flange 68 itself is engage | inserted by the outer surface (it shows with the dotted line 5) of a building frame. Although the amount of cutting of the outer surface of the building frame (indicated by the dotted line 5) increases, there is an advantage that the shear transmission force is increased because the surface area in contact with the outer surface of the building frame is increased in the fitting recess 5a. Further, there is an advantage that the process of forming the protrusion as the back side cotter of the flange 68 can be omitted.

  In addition, also about the joining member which concerns on said 1st embodiment-7th embodiment, it is the form by which flange itself is engage | inserted by the outer surface (it shows with the dotted line 5) of a building frame like the joining member 90 which concerns on 8th embodiment. A joining member can be attached to the outer surface of the building frame.

  The seismic reinforcement using the joining member according to the present invention as described above can be applied to buildings of any structural type such as a steel structure, a reinforced concrete structure, and a steel reinforced concrete structure.

  Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.

  For example, in the said embodiment, although the steel frame which consists of H-section steel 3 is used as a seismic reinforcement member, as a seismic reinforcement member, the shape steel of another shape (I shape steel, L shape steel, channel shape steel, It may be a steel frame made of angle steel or the like, or a steel frame made of flat steel. Moreover, as a seismic reinforcement member, the shape steel or the other shape which does not make flat steel the frame shape may be sufficient. Moreover, as a seismic reinforcement member, a brace, precast concrete, concrete, a damper, etc. may be sufficient.

  Moreover, in the said embodiment, although the H-section steel 3 of an earthquake-resistant reinforcement member is being fixed to the joining member by the fixing bolt 22, the H-section steel 3 of an earthquake-resistant reinforcement member is a joining member by other joining methods, such as welding. It may be fixed to. Furthermore, in the said embodiment, although the cylindrical thing is shown, it may replace with a cylindrical shape and square tube shape may be sufficient.
