Description

  The present invention relates to a seismic control pillar structure provided between upper and lower frame bodies.

As a seismic control column provided in a column beam structure, a seismic control column that absorbs energy by plastic deformation when a horizontal force is applied and suppresses the influence on other structures is known.
On the other hand, when a high compression axial force or a tensile axial force at the time of occurrence of an earthquake is applied to the seismic control column, the vibration suppressing effect is reduced and buckling may occur.
Therefore, seismic control columns that do not bear the axial force have been developed.
For example, the present applicant has disclosed a seismic control column constituted by a steel member that is plasticized when a predetermined horizontal load is applied (see, for example, Patent Document 1 or Patent Document 2). In this seismic control column, a discontinuity with a gap is formed between the upper bracket suspended from the beam on the upper floor and the lower bracket standing on the beam on the lower floor. The movement in the horizontal direction is constrained by a constraining member surrounding the part. The restraining member is fixed to the lower bracket.

Japanese Patent No. 4678098 JP 2003-129690 A

In the conventional seismic control column, a lower bracket larger than the outer diameter of the upper bracket is disposed so as to cover the flange or web of the steel member constituting the upper bracket, and a plurality of steel materials (restraints) are arranged on the upper surface of the lower bracket. Member) needs to be arranged, and therefore the lower bracket tends to be large. If the lower bracket is large, it may affect the usable space of the building. Moreover, in order to arrange | position several steel materials (restraint member), high precision management is needed at the time of construction.
In addition, in conventional seismic control columns, a plate-shaped ultra-low yield point steel without ribs is joined to the web part of the steel member that constitutes the upper bracket or lower bracket, and the ultra-low yield point steel is plasticized. The earthquake energy was absorbed. Therefore, when large deformation occurs in the extremely low yield point steel due to a large earthquake, the original seismic control effect of the ultra low yield point steel is not exhibited by concentrating the deformation on a part of the extremely low yield point steel. As it was, there was a risk of local plasticization. For this reason, conventional seismic control columns are difficult to control seismic energy and require a lot of work. Further, in the conventional seismic control column, since the ultra-low yield point steel is incorporated in the steel member, it is difficult to replace the plasticized ultra-low yield point steel.
Therefore, the present invention proposes a seismic control stud structure that can be easily constructed without affecting the living space and that exhibits a high seismic control effect without transmitting axial force. This is the issue.

  The present inventors have provided a horizontal slit in the middle part of the intermediate column, and an upper vertical material sandwiching the horizontal slit so that axial force is not applied to the vibration control column as a vibration control column structure provided in the column beam frame. By forming bearing plates on the lower vertical members and engaging the ends of these bearing plates in the horizontal direction, a vertical member is formed without causing buckling of the seismic control columns. The invention has led to the invention of a seismic control column structure with a high seismic control effect that can easily adjust the proof stress and rigidity of the seismic energy absorbed by the low yield point steel.

In order to solve the above problems, the present invention provides an upper connecting member connected to an upper beam in a column beam frame, a lower connecting member connected to a lower beam in the column beam frame, and the upper An energy absorbing member provided on the connecting member or the lower connecting member; a first support member projecting downward from the lower end surface of the upper connecting member; and a second support projecting upward from the upper end surface of the lower connecting member. A seismic isolation pillar structure including a pressure member, wherein one of the first support member and the second support member is formed to sandwich the other, and the first support member and A gap is formed between the second supporting member, between the first supporting member and the upper end surface of the lower connecting member, and between the second supporting member and the lower end surface of the upper connecting member. It is characterized by having.
According to such a seismic control inter-column structure, since axial force is not transmitted by the gap in the horizontal direction, it is possible to prevent buckling of each connecting member even when a large axial force is generated in the column beam frame. . Further, by providing a horizontal slit between the upper and lower connecting members, structural safety can be ensured because deformation is not restrained and stress is not transmitted with respect to deformation or stress generated in the out-of-plane direction of the column beam frame. Specifically, when a horizontal force is applied to the column beam frame, the first and second support members are engaged in the horizontal direction, so that the energy absorbing member disposed in advance is arranged. Since the horizontal force is transmitted to the seismic energy, the seismic energy is efficiently absorbed. Furthermore, since the 1st bearing member and the 2nd bearing member are installed between the flanges which form an upper connection member or a lower connection member, the enlargement of a member can be suppressed.

The energy absorbing member is made of a low yield point steel plate, and the low yield point steel plate is provided with stiffeners vertically and horizontally, so that even when a large horizontal force is applied, In this case, the shear deformation is not concentrated on the surface, and the shear deformation is generated almost uniformly to absorb the seismic energy. In addition, the energy absorbing member includes an upper connecting member or a lower connecting member by attaching a vertical stiffener on one surface and a horizontal stiffener on the other surface. The main steel frame material and the energy absorbing member can be easily and accurately joined.
Further, when maintaining and managing for a long time, the upper connecting member is joined to the upper member and the lower member by bolt joining, and the energy absorbing member is installed in the lower member. By replacing only the lower member provided with the energy absorbing member without removing the respective upper members from the column beam frame, the seismic control column structure at the time of installation can be maintained.

  According to the seismic control column structure of the present invention, the seismic control column can be easily constructed without affecting the living space and has a high seismic control effect without transmitting axial force. It becomes possible to construct a structure having a structure.

The present invention provides a seismic control column structure that suppresses the influence on other structures by absorbing the seismic energy by plastic deformation when a horizontal force is applied, as a seismic control column structure provided in a column beam structure. In addition, by providing a horizontal slit in the middle part of the stud and engaging the upper and lower vertical members sandwiching the horizontal slit in the horizontal direction, it has a high vibration control effect in which axial force is not transmitted.

The seismic control column structure 1 of the present embodiment includes a lower end surface of the first bearing member 5 and an upper end surface of the lower connecting member 3 (top plate 34), and an upper end surface and an upper portion of the second bearing member 6. Since a gap S (horizontal slit) is formed between the lower end surface of the connecting member 2 (bottom plate 24), no axial force is borne. Therefore, according to the seismic control column structure 1, it is possible to prevent buckling of the upper connecting member 2 and the lower connecting member 3 even when a large axial force is generated in the column beam frame 7.
Further, since a gap S is also formed between the first bearing member 5 and the second bearing member 6, the upper connecting member 2 and the first bearing member 5 and the second bearing member 6 are connected to each other. No axial force is transmitted between the lower connecting member 3. Furthermore, since the first bearing member 5 and the second bearing member 6 are provided with the friction reducing members 51 and 61 on the surfaces facing each other, the first bearing member 5 and the second bearing member 6 are subjected to the first bearing pressure by a lateral force such as during an earthquake. Even when the member 5 and the second supporting member 6 are in contact with each other, the transmission of the axial force between the upper connecting member 2 and the lower connecting member 3 is suppressed.
Further, when a horizontal force is applied to the column beam frame 2, the first support member 5 and the second support member 6 are engaged in the horizontal direction. Therefore, when a large horizontal force, such as during an earthquake, acts on the column beam frame 2, the horizontal force is transmitted to the energy absorbing member 4 disposed on the upper connecting member 2, and the horizontal energy is efficiently generated. Absorbed.

Since the vertical stiffeners 41 and 41 are attached to the energy absorbing member 4, the energy absorbing member 4 can be easily joined to the bottom plate 24 and the intermediate plate 25. Moreover, since the horizontal stiffener 42 is attached to the energy absorbing member 4, it is easy to join the left and right flanges 22, 22.
Moreover, since the vertical stiffener 41 of the energy absorbing member 4 is arranged, the shear deformation region can be changed. If the shear deformation region is deformed, the necessary proof stress and rigidity can be easily adjusted. That is, the energy absorbing material 4 is divided into three parts by the vertical stiffener 41 to ensure the necessary proof strength and rigidity.

Moreover, since the 1st bearing member 5 and the 2nd bearing member 6 are each formed in the baseplate 24 of the upper connection member 2, and the top plate 34 of the lower connection member 3, it suppresses the enlargement of a member. it can. That is, since the first bearing member 5 and the second bearing member 6 are within the outer dimensions of the upper coupling member 2 and the lower coupling member 3, respectively, the lateral dimension of the damping column structure 1 is required. Minimized. Therefore, the influence on the living space of the building can be minimized.
Since the first bearing member 5 is in contact with the flange 22, it is restrained by the flange 22 and functions as a strong reaction force material.

The energy absorbing member 4 is disposed so as to shield the space surrounded by the left and right flanges 22b and 22b, the bottom plate 24, and the connecting plate 27b. Since the structure of the other energy absorption member 4 is the same as the content shown in 1st embodiment, detailed description is abbreviate | omitted.
The connecting plate 27b is a steel plate fixed to the energy absorber 4 and the upper ends of the flanges 22b and 22b. The connecting plate 27b has a larger area than the outer shape of the energy absorbing member 4 and the flanges 22b and 22b. That is, the connecting plate 27b has a lateral width larger than the distance from the outer surface of one flange 22b to the outer surface of the other flange 22b, and a depth width larger than the width of the flange 22b. A plurality of through holes (not shown) are formed at the edge of the connecting plate 27b.
The upper member 2a and the lower member 2b are joined with the connecting plate 27a of the upper member 2a and the connecting plate 27b of the lower member 2b being vertically stacked with the through holes of both the connecting plates 27a and 27b being penetrated. This is done by fastening the nut N to the bolt B2.

  According to the damping column structure 1 of the third embodiment, the same effects as those of the damping column structure 1 of the second embodiment can be obtained.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and the above-described constituent elements can be appropriately changed without departing from the spirit of the present invention.
For example, the energy absorbing member 4 may be provided on the lower connecting member 2. The upper and lower coupling members are connected to the beams, but by connecting to the slab, the seismic control column structure can be arranged without being limited to the column beam structure of the building. It becomes.
Moreover, although the said embodiment demonstrated the case where one plate-shaped member was employ | adopted as the energy absorption member 4, you may form the energy absorption member 4 by combining several plate material. If the energy absorbing member 4 is subdivided, the required energy absorbability can be accommodated.
Further, the gap S formed between the upper connecting member 2 and the lower connecting member 3 may be filled with a low elastic material. For the low elastic material, for example, a low elastic resin can be used.
