  However, if the respective structures of the existing part and the additional part in the building are independent, for example, when an earthquake occurs, independent shaking occurs. Here, there is a concern that the existing portion of the existing portion and the additional portion may be damaged due to a difference in the magnitude of shaking. This is because it is considered that the structural strength is not the same between the existing part and the additional part. For example, if the existing part is constructed with an earthquake resistance standard older than the current earthquake resistance standard (for example, the earthquake resistance standard before 1980), the structural strength is lower than the additional part constructed with the current earthquake resistance standard. It may be set.

  The main object of the present invention is to increase the vibration resistance of the existing part by the additional part, and to keep the entire building after the extension in a suitable state even if rolling occurs.

  In order to solve the above-mentioned problem, the building of the first invention is a building in which a second building is added to the side of the existing first building so that the second building is structurally independent. 2 building has a building unit of a ramen structure consisting of pillars and large beams, and transmits the force from the first building side to the second building side when rolling of the first building occurs, A regulating member for regulating horizontal shaking of the first building relative to a second building is provided, the regulating member having one end fixed to the unit housing of the second building and the other end of the first building. It is provided so that it may extend toward an object.

  According to 1st invention, the 2nd building (additional part) added to the side of the 1st building (existing part) consists of a building unit of a ramen structure, and is the 1st building with respect to the 2nd building. Horizontal shaking is regulated by the regulating member. For this reason, for example, when a horizontal load (lateral force) is generated in each building due to rolling during an earthquake or strong wind, the second building can withstand the horizontal load, and in the first building, The horizontal movement is regulated by the regulating member with reference to the second building. That is, even when the second building is structurally added to the existing first building, the load resistance performance of the second building can be provided to the first building. In this case, since the resistance to the horizontal load of the first building can be increased with the assistance of the unit housing of the second building (building unit housing), the resistance to the horizontal load in the first building itself. Even if it is comparatively small, the damage of the 1st building resulting from a horizontal load, etc. can be controlled.

  Therefore, the vibration resistance of the existing portion can be increased by the additional portion, and as a result, the entire building after the expansion can be maintained in a suitable state even if rolling occurs.

  In addition, as a structure which a control member transmits force to the 2nd building side from the 1st building side, the edge part on the opposite side to the direction fixed to the 2nd building in the control member is the 1st building.

The force is transmitted from the first building frame to the second building unit frame.

  According to the third invention, when rolling occurs due to an earthquake or a strong wind, when the first building is relatively displaced with respect to the second building, the entire first building is reinforced so as to shake integrally. It is possible to regulate the shaking of the first building with respect to the second building after being integrated (restrained and collected) by the cross member. Therefore, it is possible to suitably perform the rolling control in the entire first building.

  In 4th invention, in the said 1st building, in the opposing side surface part which opposes the said 2nd building among each side surface part of this 1st building, the said reinforcement of the said 2nd building A reinforcing cross member is provided at the same height as the ceiling beam of the building unit, and the restricting member is connected to the ceiling beam of the second building from the housing of the first building via the reinforcing cross member. To transmit power.

  According to the fourth aspect of the invention, when rolling occurs due to an earthquake or strong wind, first, the horizontal load is regulated at the opposing side surface facing the second building in the first building. In this case, the regulating action of the horizontal load extends to the frame of the first building via the reinforcing cross member as the reinforcing material on the first building side, and as a result, the rolling of the entire first building is regulated. The Rukoto.

  By applying the fourth invention to the third invention, a configuration in which the reinforcing cross member is provided in a state of surrounding the entire first building can be realized. According to this structure, the effect | action of the rolling control of the 1st building with respect to a 2nd building can be exhibited more suitably in a 1st building. That is, it is possible to spread the roll control action throughout the first building.

  In 5th invention, in the said 1st building, the reinforcement pillar which supports the said reinforcement horizontal member from the downward direction is provided in the side part in which the said reinforcement horizontal member is provided among each side surface part of this 1st building It has been.

  According to the fifth invention, in the first building, the reinforcing cross member can be held in a stable state by supporting the reinforcing cross member provided in the direction extending in the horizontal direction with the reinforcing support column, and in the event of an earthquake. It is possible to stably exert the rolling control effect during wind and strong winds.

  In the configuration in which the reinforcing cross member is continuously provided on the two adjacent side surfaces in the first building, it is preferable that the reinforcing column is provided in the protruding corner portion of the first building. As a result, the reinforcing cross member can be held in a stable state at the protruding corner portion or the entering corner portion where stress tends to concentrate.

  In a sixth aspect of the invention, the second building is added to each side of at least two side portions of the first building in a structurally independent manner, and the regulating member is It is each provided between the 2nd building and the said 1st building.

  According to the sixth aspect of the invention, for example, when rolling occurs due to an earthquake or a strong wind, it is possible to apply a resistance against a horizontal load from a plurality of second buildings to a plurality of side portions of the first building. Therefore, damage to the first building caused by the horizontal load can be more reliably suppressed.

Of the columns 15a and 15b, the column 15a is a through column 15a provided so as to straddle the upper and lower floors, and the column 15b is a tube column 15b provided for each floor. The through column 15a is disposed at a corner such as the protruding corner of the first building 11, and the tube column 15b is disposed at an intermediate position between adjacent corners. In addition to the columns 15a and 15b, examples of the frame of the first building 11 include floor beams and ceiling beams.

  The second building 12 has a single floor, and is placed on a second foundation 16 that is structurally independent from the first foundation 14. The second foundation 16 as an additional foundation is a reinforced concrete cloth foundation, and has a footing portion embedded in the ground and a rising portion extending upward from the footing portion. The second foundation 16 is arranged at a position where the non-embedded parts are separated from the first foundation 14, and the separation dimension of the non-buried parts depends on the width dimension of the footing portion of the second foundation 16. It is set (for example, 1 m).

  The second building 12 is formed by a building unit 20 having a steel frame ramen structure. Here, the building unit 20 will be described with reference to FIG. FIG. 3 is a perspective view showing the configuration of the building unit 20.

  As shown in FIG. 3, in the building unit 20, columns 21 are arranged at the four corners, and the upper end and the lower end of each column 21 are connected by four ceiling beams 22 and floor beams 23, respectively. A rectangular frame (frame) is formed by the pillars 21, the ceiling beams 22 and the floor beams 23. The column 21 is made of a square tube-shaped square steel. Moreover, the ceiling beam 22 and the floor beam 23 are made of channel steel having a U-shaped cross section, and are installed so that the openings thereof face each other.

  A plurality of small ceiling beams 25 are bridged at predetermined intervals between the large ceiling beams 22 that extend along the long side portion (girder surface) of the building unit 20 and face each other. Similarly, a plurality of floor beams 26 are bridged at predetermined intervals between the large floor beams 23 that extend along the long side of the building unit 20 and face each other. The ceiling beam 25 and the floor beam 26 are horizontally provided at the same interval and at positions corresponding to the top and bottom.

  In the building unit 20, a ceiling surface material 27 is attached to the ceiling beam 25, and a ceiling part is formed by the ceiling beam 25 and the ceiling surface material 27. 28 is attached, and a floor portion is formed by the floor beam 26 and the floor surface material 28. In the building unit 20, a unit housing is constituted by a skeleton including columns 21, ceiling beams 22, and floor beams 23.

  In the building unit 20, the girder surface (longitudinal side surface) is a connection surface for the first building 11, and an outer wall surface material is attached to a side surface other than the connection surface. Moreover, in this embodiment, the bathroom is provided by assembling the unit bath to the building unit 20 constituting the additional portion, and in addition to this, kitchen facilities and toilet facilities are appropriately assembled. Illustrations of the unit bath, kitchen facilities, and toilet facilities are omitted.

  In the building unit 20, the connecting portion between the column 21 and the large beams 22 and 23 is rigidly connected, and resistance to vibration (vibration resistance) is increased. For this reason, the second building 12 is given a higher vibration resistance than the first building 11 by the building unit 20 having a ramen structure.

  Returning to the description of FIG. 2, the second building 12 is constructed by installing the building unit 20 using the site where the first building 11 is constructed as an existing building as a construction site. Is separated from the housing of the first building 11. In the present embodiment, the structure of the building 10 is the entire building 10 including the buildings 11 and 12, even if the housings of the first building 11 and the second building 12 are separated (structurally independent). The vibration resistance of can be increased.

  Next, the load-bearing structure of the building 10 will be described.

  A reinforcing material having high rigidity is attached to the first building 11 of the building 10. As the reinforcing material, there are a reinforcing cross member 31 provided at substantially the same height as the ceiling beam 22 of the second building 12 and a reinforcing support column 32 that supports the reinforcing cross member 31 from below. The reinforcing cross member 31 and the reinforcing support column 32 are respectively arranged on the outdoor side of the first building 11, and are connected to the columns 15 a and 15 b of the first building 11 through a connecting member 34.

  The reinforcing cross member 31 is formed in a long shape from a high-rigidity material such as channel steel, and is disposed on each side portion of the first building 11. In this case, the reinforcing cross member 31 connects the adjacent columns 15 and 15b of the first building 11 on the outdoor side of the outer wall of the building. Here, the ceiling height of the second building 12 is larger than the first floor portion 11a of the first building 11, and the reinforcing cross member 31 is above the upper and lower floor boundaries of the first building 11 (second floor). It is arranged on the part 11b side). In this case, the reinforcing cross member 31 is connected to the middle portion of the through column 15a or the lower end of the tube column 15b of the second floor portion 11b.

  The reinforcing column 32 is formed in a long shape with a high-rigidity material such as a square steel pipe, and is disposed outside the protruding corner portion of the first building 11 and at an intermediate portion between adjacent protruding corner portions. In the reinforcing column 32, the upper end portion is connected to the intermediate portion of the through column 15 a or the lower end portion of the tube column 15 b of the second floor portion 11 b in the same manner as the reinforcing cross member 31. The reinforcing column 32 is placed on the column base 35. The column foundation 35 is a reinforced concrete foundation installed on the side of the first foundation 14, and is in contact with the first foundation 14 while being separated from the second foundation 16.

  The connecting member 34 is formed of a metal material, and is fixed to each of the reinforcing cross member and the column with a fixing tool such as a bolt in a state of penetrating the outer wall of the first building 11. Incidentally, a waterproof material such as a sealing material is attached to a through portion of the connecting member 34 on the outer wall surface of the first building 11.

  In addition, the support | pillar foundation 35 does not need to be provided. However, in this case, it is preferable that the lower end portion of the reinforcing column 32 is connected to the columns 15 a and 15 b of the first building 11. The ceiling height of the second building 12 may be smaller than the ceiling height of the first floor portion 11a of the first building 11. In this case, the reinforcing cross member 31 is disposed below the boundary between the upper and lower floors of the first building 11, and is connected to the middle part of the through pillar 15a or the upper end of the pipe pillar 15b of the first floor part 11a. preferable.

  A vibration damping device 41 is attached to the building unit 20 of the second building 12 as a regulating member that regulates horizontal shaking of the first building 11 with respect to the second building 12. The damping device 41 has a damping damper, and the reinforcing cross member 31 and the pillar of the second building 12 are provided in a portion where one side surface of the first building 11 and one side surface of the second building 12 face each other. 21 is arranged between the upper end portion of 21. In this case, one end of the vibration damping device 41 is fixed to the upper end portion of the column 21 of the second building 12, and the other end protrudes toward the reinforcing cross member 31.

  The vibration damper is a hydraulic damper having a cylinder and a rod that slides at least partially in the cylinder, and having a hydraulic chamber filled with hydraulic oil in the cylinder. In the vibration damping device 41, one of the cylinder and the rod is fixed to the reinforcing cross member 31 while the vibration damping damper is extendable in the horizontal direction, and the other is the column 21 of the second building 12. It is being fixed with respect to the upper end part.

  When a horizontal load such as an earthquake or a strong wind is applied to the building 10, it is considered that the rolling of the first building 11 is larger than that of the second building 12 due to the difference in vibration resistance. In this case, the first building 11 is rolling relative to the second building 12, but the first building 11 with respect to the second building 12 is expanded and contracted by the damping damper. The relative roll of is attenuated. This means that the horizontal load applied to the first building 11 is transmitted to the second building 12 via the vibration control device 41.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  Since the second building 12 has increased resistance to vibration (vibration resistance) due to the ramen structure of the building unit 20, for example, even if a horizontal load is generated due to rolling during an earthquake or strong wind, It is possible to endure. In addition, relative vibration of the first building 11 with respect to the second building 12 in the horizontal direction is restricted by the vibration damping device 41. In other words, even if the second building 12 is structurally added to the existing first building 11, the load-bearing performance of the second building 12 is improved with respect to the first building 11. Can be provided. In this case, since the vibration resistance of the first building 11 can be increased with the assistance of the building unit 20 of the second building 12, the horizontal load is maintained even if the vibration resistance of the first building 11 itself is relatively small. The damage of the 1st building 11 resulting from can be suppressed.

  As described above, the vibration resistance of the existing portion can be increased by the additional portion, and as a result, the entire building after the expansion can be held in a suitable state even if a roll occurs.

  A reinforcing cross member 31 and a reinforcing support column 32 are attached to the first building 11 as reinforcing materials made of a highly rigid material, and the reinforcing cross member 31 and the reinforcing support column 32 are connected to the second building 12 via a vibration damping device 41. Are connected to the building unit 20. For this reason, when rolling occurs due to an earthquake or a strong wind, the horizontal load from the building unit 20 of the second building 12 is regulated by the first building 11 via the highly rigid reinforcing cross member 31 or the reinforcing column 32. As a result, the rolling control of the entire first building 11 is performed on the columns 15a and 15b.

  Since the reinforcing cross member 31 is connected to the ceiling beam 22 of the building unit 20 of the second building 12 via the vibration control device 41 at the portion of the first building 11 facing the second building 12, the earthquake When rolling occurs due to wind or strong wind, the horizontal load is first regulated at the opposite side surface portion of the first building 11 that faces the second building 12. In this case, the regulating action of the horizontal load extends to the frame such as the pillars 15a and 15b of the first building 11 via the reinforcing cross member 31, and as a result, the rolling regulation of the entire first building 11 is performed. It becomes.

  A reinforcing cross member 31 is provided so as to surround the first building 11 in the horizontal direction on the side surface portion of the first building 11 other than the side surface portion facing the second building 12. For this reason, when the first building 11 is relatively displaced with respect to the second building 12, the second building 12 is integrated with the reinforcing cross member 31 so that the entire first building 11 is shaken integrally. The vibration of the first building 11 with respect to the building 12 can be restricted via the vibration control device 41. Therefore, the rolling regulation in the first building 11 as a whole can be suitably performed.

  Since the reinforcing cross member 31 is provided so as to surround the entire first building 11, the rolling control of the first building 11 with respect to the second building 12 is more suitable for the first building 11. Can be demonstrated. That is, it is possible to spread the roll control action throughout the first building 11.

  Since the reinforcing cross member 31 is arranged at the same height as the ceiling beam 22 of the second building 12, the vibration control device 41 controls the relative roll of the reinforcing cross member 31 with respect to the ceiling beam 22 of the second building 12. It can regulate more suitably. And since the reinforcement cross member 31 can be arrange | positioned in the intermediate position of the two-story 1st building 11 in an up-down direction, compared with the case where the reinforcement cross member 31 is arrange | positioned at the upper end side or lower end side of the 1st building 11. It is convenient in restricting the rolling of the first building 11.

  In the first building 11, the reinforcing cross member 31 is supported by the reinforcing support 32, so that the reinforcing cross member 31 can be held in a stable state, and thus stably exerts the rolling control effect during an earthquake or a strong wind. Can be made. In addition, in the configuration in which the reinforcing cross member 31 is provided so as to surround the first building 11, the reinforcing column 32 is disposed at the protruding corner portion of the first building 11, and thus the first building 11. It is possible to hold the reinforcing cross member 31 in a stable state at the projecting corner where stress is likely to concentrate when a horizontal load is applied.

  Since the reinforcing cross member 31 or the reinforcing support column 32 of the first building 11 and the building unit 20 of the second building 12 are connected by the vibration damping device 41, the horizontal direction of the first building 11 with respect to the second building 12. When restricting the sway of the direction, the horizontal load which mutually arises in these both buildings 11 and 12 can be attenuate | damped suitably.

(Other embodiments)
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  (1) The 2nd building 12 may be arrange | positioned at the side of at least 2 side part among each side part of the 1st building 11. FIG. Even in this case, the second building 12a, 12b is connected to the reinforcing cross member 31 or the reinforcing column 32 of the first building 11 via the vibration control device 41, so that the first building is constructed by the second building 12. The vibration resistance of the object 11 can be increased.

  For example, as shown in FIG. 4, the second buildings 12 a and 12 b are arranged on both sides of the first building 11. According to this configuration, for example, when rolling occurs due to an earthquake or a strong wind, it is possible to apply a resistance against a horizontal load from a plurality of second buildings 12 to a plurality of side surfaces of the first building 11. Therefore, damage etc. of the 1st building 11 resulting from a horizontal load can be controlled more certainly. In particular, since the second buildings 12a and 12b are arranged on both sides of the first building 11, the vibration resistance of the first building 11 is further increased in the direction in which the second buildings 12a and 12b are arranged. Can be increased.

  In addition, as shown in FIG. 5, the second buildings 12 a and 12 b are configured to be provided on the sides of two side portions intersecting each other among the side surfaces of the first building 11. According to this configuration, for example, when rolling occurs due to an earthquake or a strong wind, load resistance is applied from the second building 12 to the plurality of side portions intersecting each other in the first building 11, so that they intersect each other. The rolling of the first building 11 can be restricted in two directions (two directions in the horizontal direction). Thereby, the improvement of the vibration tolerance of the existing part can be achieved more suitably.

  (2) In the building 10, a part of the first building 11 may be removed when the second building 12 is added. For example, as shown in FIG. 6, it is set as the structure by which the part including the protrusion corner of the 1st building 11 was removed and the 2nd building 12 was installed in the removed part. The removed portion of the first building 11 is a recess recessed toward the inner side in the horizontal direction of the first building 11, and a reinforcing cross member 31 is provided so as to extend along the inner peripheral surface of the recess. In addition, a reinforcing column 32 that supports the reinforcing cross member 31 from below is provided. In the removed portion of the first building 11, the building unit 20 of the second building 12 is connected to the reinforcing cross member 31 or the reinforcing column 32 via the vibration control device 41.

  According to the said structure, since a part of 1st building 11 is removed and the 2nd building 12 is expanded in the removal part, it does not increase the building installation area in a site, or a building installation area by extension Even if there is an increase in the number of buildings, it is possible to increase the number of buildings so that the increase is minimized. Moreover, in this case, since the housings of the first building 11 and the second building 12 are connected by the vibration control device 41, the vibration resistance of the first building 11 can be increased by the second building 12. .

  (3) In the said embodiment, although the reinforcement cross member 31 was provided in the position which connects pillar 15a, 15b of the 1st building 11, reinforcement materials, such as the reinforcement cross member 31, are the 1st building. 11 may be provided at a position where horizontal members such as beams are connected to each other, or may be provided at a position where the columns 15a, 15b and the horizontal member are connected. Moreover, in the 1st building 11, you may attach to one pillar 15a, 15b or a horizontal member. In any case, the reinforcing material is connected to the building unit 20 of the second building 12 via the vibration damping device 41, so that the load applied to the first building 11 is transmitted via the vibration damping device 41. The structure transmitted to the reinforcing material can be realized.

  (4) The reinforcing cross member 31 may not be provided on the side surface of the first building 11 that faces the second building 12. Even in this case, it is possible to realize a configuration in which the reinforcing cross member 31 is provided on a side surface portion of each side surface portion of the first building 11 other than at least the opposing side surface portion facing the second building. In this case, it is preferable that the end of the reinforcing cross member 31 on the second building 12 side is connected to the building unit 20 of the second building 12 via the vibration control device 41.

  (5) The reinforcing members such as the reinforcing cross member 31 and the reinforcing support column 32 may be provided inside the outer wall of the first building 11.

  (6) The damping device 41 as the regulating member may be configured to include damping rubber. For example, the vibration damping device 41 has a pair of opposing plate members and a damping rubber sandwiched between the plate members, and one of the pair of plate members is a first building in a state where each plate member extends in the horizontal direction. 11 is fixed to the reinforcing material 11 and the other is fixed to the building unit 20 of the second building 12. Even in this case, when rolling occurs due to an earthquake or strong wind, the relative rolling of the first building 11 relative to the second building 12 can be attenuated by the damping rubber.

  (7) The connecting portion between the first building 11 and the second building 12 may be an expansion joint. In the expansion joint, it is preferable that the regulating member is fixed to the building unit 20 of the second building 12 but not connected to the reinforcing material of the first building 11.

  For example, it is set as the structure by which the rocking | fluctuation control metal fitting is provided in the expansion joint part as a control member. In this structure, in the opposing part of the 1st building 11 and the 2nd building 12, the swing control metal fitting is provided in the state extended toward the 1st building 11 from the building unit 20 of the 2nd building 12, A portion of the reinforcing material of one building 11 that faces the shaking regulating bracket is provided with a pair of projecting portions that project toward the shaking regulating bracket and are spaced apart from each other. The swing restricting metal fitting is arranged so that the tip end portion enters between the pair of projecting portions.

  In this case, when rolling occurs due to an earthquake or strong wind, the first building 11 rolls relatively with respect to the second building 12 so that the swing regulating bracket repeatedly contacts the inner surfaces of the pair of protrusions. The horizontal load is transmitted from the first building 11 to the second building 12 through the swing restricting bracket and the protruding portion by the contact, and the roll of the first building 11 relative to the second building 12 is large. Is restricted to be equal to or less than the distance between the pair of protrusions. Therefore, the vibration restricting bracket and the protruding portion can increase the vibration resistance of the first building 11 by the second building 12 in the same manner as the vibration damping device 41.

  A seismic isolation rubber may be provided between the restricting member and the pair of protrusions. In this case, even if the restricting member is relatively displaced with respect to the pair of projecting portions when rolling occurs, the seismic isolation rubber can suppress the contact between the restricting member and the projecting portions.

  (8) The regulating member that connects the reinforcing member of the first building 11 and the building unit 20 of the second building 12 may be a linear member such as a wire or a flexible member having flexibility. . In short, if the first building 11 and the second building 12 are connected in a structurally independent manner and the relative displacement of the first building 11 with respect to the second building 12 can be regulated. Good.

  (9) The regulating member such as the vibration damping device 41 may be fixed to the column 21 or the floor girder 23 of the second building 12. In short, it may be fixed to the unit housing of the second building 12.

  (10) The first building 11 may not be provided with reinforcing materials such as the reinforcing cross member 31 and the reinforcing support column 32. In this case, the regulating member such as the vibration damping device 41 is connected to a frame such as the pillars 15a and 15b of the first building 11, the ceiling beam of the first floor portion 11a, and the floor beam of the second floor portion 11b, and is horizontal to the frame. It is preferable that the load in the direction is transmitted.

  (11) When the first building 11 has a roof portion provided on the second floor portion 11b, the roof portion may be supported by the second building 12 from below. For example, a part of the roof portion of the first building 11 is installed so as to cover the second building 12 from above, and the lower surface of the roof portion of the first building 11 and the upper surface of the second building 12 (roof Surface) is connected by a vibration damping device 41.
