However, in the above composite structure, since one of the housing structures and the other of the housing structures are both residential buildings such as buildings and condominiums, the vibration characteristics of one of the housing structures and the other housing structure Since the vibration properties are similar, there is a problem that the effect of canceling vibration caused by horizontal external forces such as wind and seismic force is small.
The present invention has been made in view of the above problems, and provides a composite structure having an effect of canceling vibration caused by a horizontal external force such as wind and seismic force, that is, a large damping effect.

The composite structure according to the present invention includes a tower-like structure formed of reinforced concrete, a residential structure constructed to be lower than the tower-like structure and surrounding the tower-like structure, and a tower-like structure. It is characterized by comprising a damper that connects the structure and the residential structure.
The tower-like structure is also characterized in that it includes a tower body that does not have a living room formed of reinforced concrete, and an observation room that is provided at a protruding portion of the tower body that protrudes upward from the housing structure.

According to the composite structure according to the present invention, a tower-like structure formed of reinforced concrete, and a residential structure constructed so as to be lower than the tower-like structure and surrounding the tower-like structure. In addition, since a tower-like structure and a residential structure having completely different vibration properties are connected by a damper, a composite structure having a great vibration damping effect can be obtained.
Since the tower-like structure has a tower body that does not have a living room and an observation room provided at the protruding part of the tower body, the use of the two structures can be completely separated, and the user of the residential structure Since the flow line and the user's flow line to the observation room can be completely separated, there is a merit in terms of management (security).

  1 to 3 show the best mode 1, FIG. 1 shows a longitudinal section of the composite structure, FIG. 2 shows a residential structure of the composite structure viewed from above, and FIG. The damper which connects a dwelling structure is shown.

  As shown in FIG. 1, the composite structure 1 includes a tower-like structure 2, a residential structure 3, and a damper 4 that connects the tower-like structure 2 and the residential structure 3.

  The tower-like structure 2 includes, for example, a tower body 6 that does not have a cylindrical living room extending upward from the foundation 5, and an observation room 7 provided at the upper end of the tower body 6 that protrudes upward from the housing structure 3. And an antenna tower 8 provided so as to extend upward from the upper surface of the observation room 7. At least the tower body 6 is a reinforced concrete structure (RC structure).

  The residential structure 3 is a residential building such as an office building or a condominium that is constructed so as to surround the lower part of the tower-like structure 2, and is a lower-rise building than the tower-like structure 2. . The dwelling structure 3 is a structure having a ramen structure formed by a steel structure (S structure), a reinforced concrete structure (RC structure), a steel reinforced concrete structure (SRC structure), or a steel concrete structure (SC structure).

  In the damper 4, one end 16 of the damper and the tower-like structure 2 are connected, and the other end 18 of the damper 4 and the residential structure 3 are connected. The damper 4 is connected to, for example, the beam 9 of the residential structure 3 and the outer surface 10 of the tower body 6 located just beside the beam 9 so as to extend horizontally. For example, the damper 4 connecting the beam 9 of the residential structure 3 and the tower body 6 of the tower structure 2 is placed on the outer periphery of the tower body 6 so as to surround the outer periphery of the tower body 6 for each floor of the residential structure 3. A plurality are installed at predetermined intervals. In FIG. 2, 16 dampers 4 are provided so as to surround the outer periphery of the tower body 6 for each floor of the residential structure 3, and the beam 9 of the residential structure 3 and the tower body 6 of the tower-like structure 2 are connected. An example is shown.

  As shown in FIG. 3, the damper 4 includes a rod-shaped main body 14 formed in a rod shape by an actuating body 12 that relatively moves linearly and a cylindrical housing 13. The rod-shaped main body 14 includes a cylindrical casing 13 and an operating body 12 provided across the inside and outside of the cylindrical casing 13 on the central axis of the cylinder of the cylindrical casing 13. The actuating body 12 and the cylindrical housing 13 are formed so as to be relatively linearly movable along the central axis of the cylinder.

  For example, as shown in FIG. 3, the damper 4 has a cylinder 21 as a cylindrical housing 13, and a piston whose one end is positioned in the cylinder 21 so as to straddle the inside and outside of the cylinder 21 and the other end projects from one end of the cylinder 21 An oil damper having a rod 22, a piston 23 provided on a piston rod 22 positioned in the cylinder 21, a hydraulic chamber 24 partitioned by the piston 23, and an unillustrated hydraulic supply / discharge mechanism for the hydraulic chamber 24 In this case, the operating body 12 is formed by the piston rod 22 and the piston 23, and the rod-shaped main body 14 is formed by the cylinder 21, the piston rod 22 and the piston 23.

  The tower-like structure 2 is a structure that simply supports the observation room 7 at the part connected by the residential structure 3 and the damper 4, and the part other than the observation room 7 only includes an elevator shaft and an escape staircase that are not shown in the figure. It is a cylindrical structure that does not have a living room. That is, the composite structure 1 of the best mode 1 has a configuration in which the functions of the plurality of structures are connected in the vertical direction.

  The vibration property of the tower-like structure 2 and the vibration property of the residential structure 3 are completely different. The vibration property of the tower-like structure 2 has a characteristic that the bending deformation is excellent, in other words, the bending deformation becomes a dominant vibration property and shakes in a long period. The vibration property of the dwelling structure 3 is a vibration property in which shear deformation and bending deformation are combined, and has a characteristic that it swings in a shorter period than the tower-like structure 2. Therefore, when the composite structure 1 receives a horizontal external force such as wind or seismic force, the movement of the tower-like structure 2 and the movement of the residential structure 3 are completely different. Becomes larger. According to the composite structure 1 of the best mode 1, the vibration damping effect is increased as compared with the conventional composite structure in which the dwelling structure and the dwelling structure are connected by the damper.

According to the composite structure 1 of the best mode 1, a tower-like structure 2 such as a tower and a house-like structure 3 such as a building are completely different from each other. Since it is the structure connected by 4, the composite structure 1 with a large damping effect can be obtained.
According to the composite structure 1 of the best mode 1, the lower structure of the tower structure 2 that is one structure is surrounded by the residential structure 3 that is the other structure, and the tower structure 2 is a structure in which the tower-like structure 2 and the residential structure 3 are connected by the damper 4, so that the difference between the shaking of the tower-like structure 2 and the shaking of the residential structure 3 is, for example, during an earthquake. Since the damper 4 is forcibly operated, vibration energy can be efficiently absorbed.
According to the composite structure 1 of the best mode 1, since the functions of the plurality of structures are configured to be connected in the vertical direction, the use of the two structures can be completely separated, and the user of the residential structure 3 can Since the flow line and the flow line of the user in the observation room 7 of the tower-like structure 2 can be completely separated, there is an advantage in terms of management (in terms of crime prevention).
According to the composite structure of the best mode 1, the lower part of the tower body 6 connected by the dwelling structure 3 and the damper 4 is the vertical load of the protruding part of the tower body 6 protruding upward from the dwelling structure 3. Therefore, the burden on the housing structure 3 is reduced, and the axial force of the pillars of the housing structure 3 can be prevented from becoming excessive.

Best form 2
As shown in FIG. 3, the damper 4 includes one end 16 of the rod-shaped main body 14 (one end of the damper 4) and one end-side mounting portion 17 of the tower-like structure 2, and the other end 18 of the rod-shaped main body 14 (other than the damper 4. End) and the other end side end mounting portion 19 of the housing structure 3 are provided at positions shifted vertically, so that the actuating body 12 and the cylindrical housing 13 relatively linearly move ( Hereinafter, it may be configured to be attached so that the direction of relative linear motion is inclined in the vertical direction with respect to the horizontal plane 11.

  According to the best mode 2, the damper 4 is installed so as to be inclined in the vertical direction with respect to the horizontal plane 11, that is, so that the relative linear motion direction is inclined in the vertical direction with respect to the horizontal plane 11. Since the damper 4 is attached, for example, in the tower-like structure 2 that is a structure having a high aspect ratio and receives a horizontal external force, the bending deformation is dominant (the bending deformation becomes dominant). When the object 2 receives a horizontal external force such as wind or earthquake, the bending direction of the tower body 6 and the relative linear motion direction of the damper 4 are the same direction, so that the effectiveness of the damper 4 is improved. In addition, since the effectiveness of the dampers 4 with respect to the horizontal external force is improved, the number of dampers 4 can be reduced, or the dampers 4 having a small maximum damping force can be used.

  As the damper 4, a damper such as a viscous material damper, a friction damper, or a steel damper may be used.
