Description

  The present invention relates to a structural member, a frame, and a building, and more specifically, a long bar-shaped structural member that bears a horizontal force acting on the frame of the building and bends and deforms, and a frame including the structural member, and The present invention relates to a building provided with the frame.

  Conventionally, as a structural form of a building, a composite structure is used in which a frame structure composed of columns and beams, an intermediate member such as a stud provided in the frame, and diagonal members such as streaks and braces are used. . In such a composite structure, the vertical and horizontal loads (seismic load and wind load) of the building are supported by the rigid frame, and the horizontal load is mainly borne by the intermediate members and diagonal members, thereby providing earthquake resistance (wind resistance). It is supposed to enhance the sex. As a composite structure, a brace structure including an intermediate member (intermediate column) provided by connecting intermediate positions of the upper and lower beams, and a brace extending and connected to the intermediate member from four column beam joints. Has been proposed (see, for example, Patent Document 1). In this brace structure, the eccentric position of the intermediate member (between the connecting positions of the upper and lower braces) is concentrated by shifting the connecting positions of the pair of upper braces and the pair of lower braces up and down with respect to the intermediate member. Shear deformation is performed, and this eccentric part is used as an energy absorbing material.

Japanese Patent Laid-Open No. 10-227061

  However, in the structure in which stress is concentrated on the eccentric part of the intermediate member and the energy is absorbed by the plastic deformation as in the conventional structure described in Patent Document 1, the peripheral member of the energy absorbing material is strengthened. Therefore, it is necessary to provide a mechanism for preventing additional stress from acting on the peripheral members, which complicates the structure and increases the cost of materials and construction. Furthermore, in the conventional structure that concentrates stress on the energy absorber, it is necessary to increase the rigidity of the peripheral members of the energy absorber, and the initial stiffness of the entire frame becomes too high. In addition, there is a problem that the input to the building becomes excessive, the fixing portion of the column and the column beam joint are damaged, and the structural performance cannot be sufficiently improved.

  Therefore, an object of the present invention is to provide a structural member, a frame body, and a building that can improve structural performance while preventing an increase in cost.

  The structural member of the present invention is a long bar-like structural member that bears a horizontal force acting on a building frame and bends and deforms, and a member body that extends in the material axis direction, and a bending direction that intersects the material axis direction A viscoelastic member that is laminated on at least a part of the surface of the member main body along the material axis of the member main body, and a layer that covers the surface of the viscoelastic member, and the member main body and the viscoelastic member And a covering member to be integrated.

  According to the present invention as described above, when a viscoelastic member is provided between the member main body and the covering member on at least one side in the bending direction, the structural member is bent and deformed to generate a shearing force. In addition, the viscoelastic member is elastically deformed and a resistance force (damping force) is generated by the viscosity. By providing such a structural member as a bending material at an appropriate position in the building to bear a horizontal force, energy can be absorbed with a simple configuration and deformation performance can be improved. Furthermore, the structural member can have substantially the same size and shape as a conventional bending material, and an increase in construction cost can be prevented.

  In addition, if a structural member having the same size as that of a conventional bending material is used, since the viscoelastic member is provided, bending rigidity can be suppressed and viscosity can be imparted. The initial rigidity of the (building) can be suppressed to reduce input energy such as earthquake motion, and the vibration absorption performance can be improved.

  At this time, in the structural member of the present invention, it is preferable that the member main body and the covering member are made of a laminated material or a solid material of wood or bamboo.

  According to such a structure, the structural member which has appropriate rigidity can be manufactured by selecting and combining the material of a member main body and a covering member from wood or bamboo. In addition, the same raw material may be used for a member main body and a covering member, and mutually different materials may be used. Furthermore, it is preferable that the member main body and the covering member are made of a laminated material. According to such a configuration, when the laminated material is manufactured, the structural member of the present invention is manufactured by a manufacturing method in which the viscoelastic member is sandwiched between the member main body and the covering member and bonded together. Can do. Therefore, in the same manufacturing process of laminated materials as in the past, it is only necessary to make a minor change by adding the bonding process of the viscoelastic member, so there is no need to greatly change the manufacturing equipment and manufacturing process, and the manufacturing cost of the structural member is reduced. Increase can be suppressed.

It is further provided with the auxiliary | assistant material erected.

  According to such a frame structure of the present invention, when a horizontal force acts on the frame structure, the secondary material bears the axial force as a brace, resists the horizontal force, and by the axial force borne by the secondary material A bending moment and a shearing force are generated in the structural member. Since the structural member generates a resistance force (damping force) against such a force, the toughness due to bending deformation can be increased while suppressing the horizontal rigidity of the frame body. Therefore, it is possible to reduce the input acceleration of seismic motion by suppressing the horizontal rigidity, improve the deformation performance by high toughness, and maintain the restoring force against external force such as seismic motion that is repeatedly input. High hysteresis energy absorption performance can be exhibited.

  At this time, in the frame body of the present invention, the structural member is provided across the upper and lower horizontal members in the middle of the pair of vertical members, and the secondary member is an upper end portion of the pair of vertical members.

And a second connecting member. Arbitrariness. According to such a configuration, when a structural member is installed as a stud and each diagonal member as a secondary material is connected to an intermediate portion of the structural member, when a horizontal force acts on the frame body, as described above. The structural member functions as a bending material and can exhibit high energy absorption performance.

  Furthermore, in the frame of the present invention, the structural member is provided to extend from one upper end portion of the pair of vertical members to the lower end portion of the other, and the auxiliary material is formed of the pair of vertical members.

The stud 11 and the angle 24 are fastened by a bolt 25 and a nut 26, and the angle 24 is formed with a loose hole 24a having a movable range of, for example, 10 mm above and below.

  The viscoelastic member 112 is formed in a sheet shape or a tape shape from a resin material or the like having appropriate elasticity and viscosity, and is sandwiched between the member main body 111 and the covering member 113, and is adhered to and integrated with them.

  In the frame 1 and the frame 10 described above, the dimensions of each part are set such that, for example, the column span L that is the interval between the left and right columns C is 910 mm, and the internal height H that is the distance between the upper and lower beams G is 2700 mm. Has been. In addition, the connection positions of the upper diagonal member 12 and the lower diagonal member 13 with respect to the stud 11, that is, the positions of the upper and lower pin connecting members 15, 17 are separated by a substantially equal distance vertically across the center position in the longitudinal direction of the stud 11. The distance between the upper and lower pin connection members 15, 17 is set to about ３ of the length of the stud 11. In addition, the position of the pin connection members 15 and 17 along the longitudinal direction of the stud 11 may be a position that causes bending deformation in the stud 11 as will be described later, and the pin connection members 15 and 17 are too close to each other.

  Next, the operation of the frame body 10 will be described. When an external force such as an earthquake is input to the building, a horizontal force that causes the frame 1 to undergo shear deformation acts. For example, in FIG. 1, when a horizontal force from left to right or from right to left is applied to the position of the beam G1, a tensile axial force is generated in one of the pair of upper diagonal members 12, and a compression axial force is applied to the other. A compression axial force is generated on one of the pair of lower diagonal members 13, and a tensile axial force is generated on the other. As a result, a bending moment and a shearing force are generated in the central portion between the upper and lower pin connecting members 15 and 17 in the inter-column 11, and the bending moment and the shearing force in the reverse direction about the center in the longitudinal direction of the inter-column 11 are The stud 11 is deformed into an S shape. That is, the stud 11 functions as a bending material that bears a bending moment and a shearing force, and resists a horizontal force by the restoring force of the bending deformation. At this time, as described above, the damping force by the viscoelastic member 112 of the stud 11 is exhibited, and the vibration of the building can be suppressed.

  According to the present embodiment described above, since the stud 11 includes the viscoelastic member 112 between the member main body 111 and the covering member 113, a resistance force against a shearing force can be generated. Furthermore, since such a stud 11 functions as a bending material, toughness due to bending deformation can be enhanced while suppressing the horizontal rigidity of the frame body 10. Therefore, it is possible to reduce the input acceleration such as seismic motion by suppressing the horizontal rigidity, improve the deformation performance by high toughness, and maintain the restoring force against the external force such as seismic motion repeatedly input. High hysteresis energy absorption performance.

  Furthermore, in each part of the upper first connection member 14, the upper pin connection member 15, the lower first connection member 16, and the lower pin connection member 17, three or more connection members overlap and are connected to the same part. In this case, the structure of the connecting portion can be simplified. For this reason, the member shape of each connecting member can be simplified and reduced in size, and the connecting operation can be performed easily and quickly, and the material cost and construction cost of each member can be suppressed.

[Second Embodiment]

The upper and lower pin connection members 15B and 17B are spaced apart from each other by a substantially equal distance across the position, and the distance between the upper and lower pin connection members 15B and 17B is set to about 1/3 of the length of the main diagonal member 11B. The positions of the pin connection members 15B and 17B along the longitudinal direction of the main diagonal member 11B may be any positions that cause bending deformation of the main diagonal member 11B.

  Next, the operation of the frame body 10B will be described. For example, in FIG. 3, when a horizontal force from left to right is applied to the position of the beam G1, a tensile axial force is generated in the main diagonal 11B, and this main diagonal 11B functions as a brace. At the same time, a compression axial force is generated in the upper diagonal member 12B and a compression axial force is generated in the lower diagonal member 13B, and the component force of these axial forces is transmitted to the main diagonal member 11B as an axial force and a shearing force. A bending moment is generated in the main diagonal 11B. A bending moment and a shearing force are generated in the main diagonal 11 </ b> B upside down around the center in the longitudinal direction, and the main diagonal 11 </ b> B is deformed into an S shape. That is, the main diagonal member 11B functions as a brace that bears an axial force, and also functions as a bending member that bears a bending moment and a shearing force, and resists horizontal force by the restoring force of the bending deformation. At this time, substantially the same as in the first embodiment, the damping force by the viscoelastic member 112 is exhibited, and the vibration of the building can be suppressed.
