Description

本開示は、構造物の振動を抑制する制震装置に関する。 The present disclosure relates to a vibration control device that suppresses vibration of a structure.

一般に、住宅に用いられる制震装置は、水平方向に延在すると共に上下方向において対向する上部水平材および下部水平材の間に設けられている。また、制震装置は、下部水平材に設けられた下部伝達部材と、上部水平材に設けられた上部伝達部材と、下部伝達部材と上部伝達部材との間に設けられ、下部伝達部材と上部伝達部材との相対変位を抑えるダンパとを備えている。この場合、地震等が発生して上部伝達部材と下部伝達部材との間に相対変位が生じると、この相対変位によってダンパが伸長、縮小して減衰力を発生する。これにより、制震装置は、住宅の振動を抑制している（特許文献１）。 Generally, the seismic control device used in a house is provided between an upper horizontal member and a lower horizontal member which extend in the horizontal direction and face each other in the vertical direction. Further, the vibration control device is provided between the lower transmission member provided on the lower horizontal member, the upper transmission member provided on the upper horizontal member, and the lower transmission member and the upper transmission member, and the lower transmission member and the upper portion. It is equipped with a damper that suppresses relative displacement with the transmission member. In this case, when an earthquake or the like occurs and a relative displacement occurs between the upper transmission member and the lower transmission member, the damper expands and contracts due to this relative displacement to generate a damping force. As a result, the vibration control device suppresses the vibration of the house (Patent Document 1).

For example, the structure 1 constituting the lightweight steel-framed house is composed of a strength member provided on the floor side of each foundation or floor, and is on the ceiling side so as to face the lower horizontal member 2 extending in the horizontal direction in the vertical direction. It is provided with an upper horizontal member 3 which is located at and extends in the horizontal direction. The lower horizontal member 2 is formed as a continuous foundation made of, for example, concrete, and a lower transmission member 12 of a vibration control device 11 described later is attached to a horizontally leveled upper surface 2A. The lower horizontal member 2 is provided with a plurality of anchor bolts 2B in a state of protruding upward from the upper surface 2A. The anchor bolts 2B are separated from each other in the length direction (horizontal direction in FIG. 1) of the lower horizontal member 2, for example, so as to correspond to the bolt insertion holes 14A provided in the mounting portion 14 of the lower pillar mounting member 13 described later. Four of them are arranged at intervals. Each anchor bolt 2B is composed of an adhesive anchor that can be provided after the construction of the lower horizontal member 2, an anchor bolt embedded at the time of construction, and the like.

A bolt insertion hole 3B is provided.

次に、本実施形態の制震装置１１は、下部水平材２と上部水平材３との間の空間に設けられている。制震装置１１は、様々な構造物１に対して取付けることができる上に、安価な部品を用いることで設置コストが低く抑えられている。制震装置１１は、後述の下部伝達部材１２、上部伝達部材２８およびダンパ４６を含んで構成されている。下部伝達部材１２は、下部水平材２の上面２Ａ上に取付けられ、上部伝達部材２８は、上部水平材３の取付板部３Ａに取付けられている。そして、下部伝達部材１２の上部と上部伝達部材２８の下部との間には、ダンパ４６が設けられている。制震装置１１は、例えば地震により水平方向（左右方向）の振動が構造物１に入力されると、ダンパ４６が伸長、縮小することで発生する減衰力を利用して構造物１の振動を吸収する。 Next, the vibration control device 11 of the present embodiment is provided in the space between the lower horizontal member 2 and the upper horizontal member 3. The vibration control device 11 can be attached to various structures 1, and the installation cost is kept low by using inexpensive parts. The vibration control device 11 includes a lower transmission member 12, an upper transmission member 28, and a damper 46, which will be described later. The lower transmission member 12 is mounted on the upper surface 2A of the lower horizontal member 2, and the upper transmission member 28 is mounted on the mounting plate portion 3A of the upper horizontal member 3. A damper 46 is provided between the upper portion of the lower transmission member 12 and the lower portion of the upper transmission member 28. For example, when vibration in the horizontal direction (horizontal direction) is input to the structure 1 due to an earthquake, the vibration control device 11 uses the damping force generated by the expansion and contraction of the damper 46 to generate the vibration of the structure 1.

The lower transmission member 12 includes a lower column mounting member 13, a first lower column member 16, a second lower column member 19, a first lower reinforcing plate 22, and a lower common structural plate 23 (second lower reinforcing plate 24, lower damper), which will be described later. It is configured to include a mounting plate 25) and a lower guide member 26. Here, the lower transmission member 12 and the upper transmission member 28 described later are formed as the same member. That is, the lower transmission member 12 can be used as the upper transmission member 28 by rotating the lower transmission member 12 and inverting it upside down (see FIG. 1).

下部柱取付部材１３は、下部水平材２の上面２Ａに設けられている。この下部柱取付部材１３は、下部水平材２の長さ方向に間隔をもって２個設けられている。図５、図６に示すように、下部柱取付部材１３は、下部水平材２の長さ方向に長尺な長方形状の板体からなる取付部１４と、取付部１４の中央部から上部水平材３に向けて突出した取付突部１５とを有している。取付部１４には、下部水平材２の各アンカボルト２Ｂに対応する位置に４個のボルト挿通孔１４Ａ（図５、図６参照）が設けられている。 The lower pillar mounting member 13 is provided on the upper surface 2A of the lower horizontal member 2. Two lower pillar mounting members 13 are provided at intervals in the length direction of the lower horizontal member 2. As shown in FIGS. 5 and 6, the lower pillar mounting member 13 has a mounting portion 14 formed of a rectangular plate body elongated in the length direction of the lower horizontal member 2 and an upper horizontal portion from the center portion of the mounting portion 14. It has a mounting protrusion 15 that protrudes toward the material 3. The mounting portion 14 is provided with four bolt insertion holes 14A (see FIGS. 5 and 6) at positions corresponding to the anchor bolts 2B of the lower horizontal member 2.

取付突部１５は、取付部１４の短尺方向に延びて立設された横板１５Ａと、横板１５Ａの中央位置から下部水平材２の長さ方向に延びて立設された縦板１５Ｂとによって平面視でＴ形状の柱として形成されている。取付突部１５は、取付部１４に対して溶接手段（隅肉溶接等）を用いて一体的に固着されている。この場合、Ｔ形状の柱状体からなる取付突部１５は、様々な方向からの負荷を受け止めることができ、高い剛性を有している。横板１５Ａは、後述する下部柱部材１６，１９のアングル材１７，２０の背板１７Ａ，２０Ａが当接され、縦板１５Ｂは、アングル材１７，２０の対面板１７Ｂ，２０Ｂが当接される。 The mounting protrusions 15 include a horizontal plate 15A erected extending in the short direction of the mounting portion 14, and a vertical plate 15B erected extending from the center position of the horizontal plate 15A in the length direction of the lower horizontal member 2. It is formed as a T-shaped pillar in a plan view. The mounting protrusion 15 is integrally fixed to the mounting portion 14 by using welding means (fillet welding or the like). In this case, the mounting protrusion 15 made of a T-shaped columnar body can receive loads from various directions and has high rigidity. The horizontal plate 15A is in contact with the back plates 17A and 20A of the angle members 17 and 20 of the lower column members 16 and 19, and the vertical plate 15B is in contact with the facing plates 17B and 20B of the angle members 17 and 20.

Further, the vertical plate 15B of the mounting protrusion 15 is provided with a plurality of, for example, two bolt insertion holes 15D at intervals in the vertical direction. These bolt insertion holes 15C and 15D are arranged at positions appropriately corresponding to the bolt insertion holes 17C, 17D, 20C and 20D provided in the angle members 17 and 20. The bolt insertion hole 15C and the bolt insertion hole 15D are arranged so as not to overlap each other in the vertical direction. As a result, the fastening tool can be easily engaged with the fastening members 18 and 21 during the assembly work, and the workability can be improved.

図７に示すように、下部柱取付部材１３は、各ボルト挿通孔１４Ａにアンカボルト２Ｂが通るように取付部１４を下部水平材２の上面２Ａに配置する。２個の下部柱取付部材１３は、取付突部１５の縦板１５Ｂが互いに離れた位置となるように、対称的に配置される。この状態で、各アンカボルト２Ｂにナット２Ｃを螺着することにより、２個の下部柱取付部材１３は、それぞれ下部水平材２の上面２Ａに強固に固定されている。また、下部柱取付部材１３の取付突部１５には、後述する下部柱部材１６，１９の各アングル材１７，２０が挟持状態で取付けられる。しかも、下部柱取付部材１３は、例えば、溶接手段を用いて取付部１４、取付突部１５の横板１５Ａ、縦板１５Ｂの３枚の板材を固着することにより、簡単に、かつ安価に製造することができる。 As shown in FIG. 7, in the lower column mounting member 13, the mounting portion 14 is arranged on the upper surface 2A of the lower horizontal member 2 so that the anchor bolt 2B passes through each bolt insertion hole 14A. The two lower column mounting members 13 are symmetrically arranged so that the vertical plates 15B of the mounting protrusions 15 are positioned apart from each other. In this state, by screwing the nut 2C to each anchor bolt 2B, the two lower column mounting members 13 are firmly fixed to the upper surface 2A of the lower horizontal member 2, respectively. Further, the angle members 17 and 20 of the lower pillar members 16 and 19 described later are attached to the mounting protrusion 15 of the lower pillar mounting member 13 in a sandwiched state.

The first lower column member 16 includes a pair of angle members 17 sandwiching the first lower reinforcing plate 22, the second lower reinforcing plate 24 of the lower common structure plate 23, and the lower damper mounting plate 25, which will be described later, and a pair of angle members 17. It is composed of a fastening member 18 that is integrally fixed.

第１下部柱部材１６を構成する２本のアングル材１７は、一般的に市販されている山形鋼（アングル鋼）によって形成されている。即ち、アングル材１７は、断面Ｌ形状の山形鋼を所定の長さに切断し、複数個のボルト挿通孔１７Ｃ〜１７Ｇを穿設することにより、簡単に、かつ安価に製造することができる。しかも、このアングル材１７の製造作業は、制震装置１１を設置する現場でも行うことができる。図５に示すように、２本のアングル材１７は、下部柱取付部材１３の短尺方向（下部水平材２の長さ方向と直交する方向）で対称となるように配置されている。 The two angle members 17 constituting the first lower column member 16 are formed of generally commercially available angle steel (angle steel). That is, the angle member 17 can be easily and inexpensively manufactured by cutting angle steel having an L-shaped cross section to a predetermined length and drilling a plurality of bolt insertion holes 17C to 17G. Moreover, the manufacturing work of the angle member 17 can also be performed at the site where the vibration control device 11 is installed. As shown in FIG. 5, the two angle members 17 are arranged so as to be symmetrical in the short direction of the lower column mounting member 13 (the direction orthogonal to the length direction of the lower horizontal member 2).

このように、下部伝達部材１２を構成する各部品は、単純な形状で安価な材料を用い、単純な穴あけ加工や溶接加工等の加工を施すだけで製造することができる。即ち、下部伝達部材１２は、安価に製造でき、かつ下部水平材２に対する取付作業を容易に行うことができる。 As described above, each component constituting the lower transmission member 12 can be manufactured by using an inexpensive material having a simple shape and simply performing a drilling process, a welding process, or the like. That is, the lower transmission member 12 can be manufactured at low cost, and the attachment work to the lower horizontal member 2 can be easily performed.

次に、図１、図１２、図１３に示すように、上部伝達部材２８は、下部伝達部材１２と上下方向で対向するように、上部水平材３に設けられている。上部伝達部材２８は、上部水平材３から下部水平材２に向けて延びている。ここで、上部伝達部材２８は、下部伝達部材１２と同一の構造体として形成されている。即ち、下部伝達部材１２を１８０度回転させて上下を反転させることにより上部伝達部材２８になる。従って、上部伝達部材２８は、下部伝達部材１２の構成で用いた符号と同じ順番で新たに符号を付し、その構成の説明は省略する。 Next, as shown in FIGS. 1, 12, and 13, the upper transmission member 28 is provided on the upper horizontal member 3 so as to face the lower transmission member 12 in the vertical direction. The upper transmission member 28 extends from the upper horizontal member 3 toward the lower horizontal member 2. Here, the upper transmission member 28 is formed as the same structure as the lower transmission member 12. That is, the lower transmission member 12 is rotated 180 degrees and turned upside down to become the upper transmission member 28. Therefore, the upper transmission member 28 is newly added with reference numerals in the same order as the reference numerals used in the configuration of the lower transmission member 12, and the description of the configuration will be omitted.

上部伝達部材２８は、上部柱取付部材２９（取付部３０、取付突部３１）、第１上部柱部材３２（アングル材３３、締結部材３４）、第２上部柱部材３５（アングル材３６、締結部材３７）、第１上部補強板３８、上部共通構造板３９（第２上部補強板４０、上部ダンパ取付板４１）、上部案内部材４２（板体４３）を含んで構成されている。 The upper transmission member 28 includes an upper pillar mounting member 29 (mounting portion 30, mounting protrusion 31), a first upper pillar member 32 (angle member 33, fastening member 34), and a second upper pillar member 35 (angle member 36, fastening). The member 37), the first upper reinforcing plate 38, the upper common structure plate 39 (the second upper reinforcing plate 40, the upper damper mounting plate 41), and the upper guide member 42 (plate body 43) are included.

なお、ナット受板４４は、上部水平材３の取付板部３Ａに上部伝達部材２８の各上部柱取付部材２９を取付けるときに、取付板部３Ａの上側にそれぞれ設けられる。ナット受板４４は、上部柱取付部材２９の取付部３０と同等の長方形状の板体からなり、ボルト挿通孔３Ｂと対応するボルト挿通孔（図示せず）が設けられている。 The nut receiving plate 44 is provided on the upper side of the mounting plate portion 3A when the upper pillar mounting member 29 of the upper transmission member 28 is mounted on the mounting plate portion 3A of the upper horizontal member 3. The nut receiving plate 44 is formed of a rectangular plate body equivalent to the mounting portion 30 of the upper pillar mounting member 29, and is provided with a bolt insertion hole (not shown) corresponding to the bolt insertion hole 3B.

上部伝達部材２８は、上部水平材３の取付板部３Ａの下面に上部柱取付部材２９の取付部３０を当接させ、取付板部３Ａの上面にナット受板４４を配置する。この状態で、締結部材４５を用いて上部水平材３と取付部３０とナット受板４４とを一体的に固定する。 In the upper transmission member 28, the mounting portion 30 of the upper pillar mounting member 29 is brought into contact with the lower surface of the mounting plate portion 3A of the upper horizontal member 3, and the nut receiving plate 44 is arranged on the upper surface of the mounting plate portion 3A. In this state, the upper horizontal member 3, the mounting portion 30, and the nut receiving plate 44 are integrally fixed by using the fastening member 45.

ここで、上部伝達部材２８を上部水平材３に取付けるときには、下部伝達部材１２を構成する下部案内部材２６の各板体２７間に上部伝達部材２８の上部ダンパ取付板４１を差込む。また、上部伝達部材２８を構成する上部案内部材４２の各板体４３間に下部伝達部材１２の下部ダンパ取付板２５を差込む。これにより、下部伝達部材１２と上部伝達部材２８とが各水平材２，３の長さ方向と直交する方向にずれるのを各案内部材２６，４２によって防止でき、下部伝達部材１２と上部伝達部材２８とを各水平材２，３の長さ方向に相対移動させることができる。 Here, when the upper transmission member 28 is attached to the upper horizontal member 3, the upper damper mounting plate 41 of the upper transmission member 28 is inserted between the plate bodies 27 of the lower guide member 26 constituting the lower transmission member 12. Further, the lower damper mounting plate 25 of the lower transmission member 12 is inserted between the plate bodies 43 of the upper guide member 42 constituting the upper transmission member 28. As a result, the lower transmission member 12 and the upper transmission member 28 can be prevented from being displaced in the direction orthogonal to the length direction of the horizontal members 2 and 3, and the lower transmission member 12 and the upper transmission member 12 can be prevented from being displaced in the direction orthogonal to the length direction. 28 can be relatively moved in the length direction of each of the horizontal members 2 and 3.

ダンパ４６は、下部伝達部材１２と上部伝達部材２８との間に、上下方向に並べて２本設けられている。各ダンパ４６は、下部伝達部材１２と上部伝達部材２８との相対変位を抑える。ダンパ４６は、作動油が充填されたシリンダ４６Ａと、シリンダ４６Ａ内を摺動するピストン（図示せず）と、長さ方向の一端がピストンに結合され、他端がシリンダ４６Ａから突出したピストンロッド４６Ｂとを含んで構成されている。シリンダ４６Ａの一端側は、シリンダ取付部材４６Ｃによって下部伝達部材１２の下部共通構造板２３を構成する下部ダンパ取付板２５のダンパ取付孔２５Ｂに回動可能に取付けられている。一方、ピストンロッド４６Ｂの他端側は、ロッド取付部材４６Ｄによって上部伝達部材２８の上部共通構造板３９を構成する上部ダンパ取付板４１のダンパ取付孔４１Ｂに回動可能に取付けられている。これにより、２本のダンパ４６は、下部伝達部材１２および上部伝達部材２８の間の振動による相対変位を、ピストンに設けた減衰バルブ（図示せず）によって減衰させる。なお、ダンパは、１本または３本以上設ける構成としてもよい。 Two dampers 46 are provided between the lower transmission member 12 and the upper transmission member 28 side by side in the vertical direction. Each damper 46 suppresses the relative displacement between the lower transmission member 12 and the upper transmission member 28. The damper 46 includes a cylinder 46A filled with hydraulic oil, a piston sliding in the cylinder 46A (not shown), and a piston rod having one end in the length direction coupled to the piston and the other end protruding from the cylinder 46A. It is configured to include 46B. One end side of the cylinder 46A is rotatably attached to the damper mounting hole 25B of the lower damper mounting plate 25 constituting the lower common structure plate 23 of the lower transmission member 12 by the cylinder mounting member 46C. On the other hand, the other end side of the piston rod 46B is rotatably attached to the damper mounting hole 41B of the upper damper mounting plate 41 constituting the upper common structural plate 39 of the upper transmission member 28 by the rod mounting member 46D. As a result, the two dampers 46 dampen the relative displacement due to vibration between the lower transmission member 12 and the upper transmission member 28 by a damping valve (not shown) provided on the piston. The damper may be provided with one or three or more dampers.

地震により制震装置１１が取付けられた構造物１に水平方向の振動が入力された場合には、上部水平材３と下部水平材２が水平方向の相対変位が生じる。上部水平材３と下部水平材２との間で生じた相対変位は、下部伝達部材１２、上部伝達部材２８を通じて、各ダンパ４６に入力される。これにより、ダンパ４６は、シリンダ４６Ａ内をピストンが摺動することにより減衰力を発生して、振動エネルギを吸収する。 When horizontal vibration is input to the structure 1 to which the vibration control device 11 is attached due to an earthquake, the upper horizontal member 3 and the lower horizontal member 2 are displaced relative to each other in the horizontal direction. The relative displacement generated between the upper horizontal member 3 and the lower horizontal member 2 is input to each damper 46 through the lower transmission member 12 and the upper transmission member 28. As a result, the damper 46 generates a damping force by sliding the piston in the cylinder 46A and absorbs the vibration energy.

かくして、本実施形態によれば、下部柱部材１６，１９は、下部水平材２の水平方向に間隔をもって下部柱取付部材１３に２本取付けられ、下部水平材２から上部水平材３に向けて延びている。この２本の下部柱部材１６，１９は、互いに対面した断面Ｌ形状の２本のアングル材１７，２０と、２本のアングル材１７，２０間に下部補強板２２，２４を挟んだ状態で２本のアングル材１７，２０を締結する締結部材１８，２１とによって構成されている。 Thus, according to the present embodiment, the lower pillar members 16 and 19 are attached to the lower pillar mounting member 13 at intervals in the horizontal direction of the lower horizontal member 2, and the lower pillar members 16 and 19 are attached from the lower horizontal member 2 toward the upper horizontal member 3.

The two upper column members 32, 35 are in a state where the upper reinforcing plates 38, 39 are sandwiched between the two angle members 33, 36 having an L-shaped cross section facing each other and the two angle members 33, 36. It is composed of fastening members 34 and 37 that fasten the two angle members 33 and 36.

従って、制震装置１１は、下部柱部材１６，１９を構成するアングル材１７，２０を、一般的に市販されている山形鋼（アングル鋼）によって形成することができる。また、アングル材１７，２０は、現場で所定の長さに切断することもでき、複数個のボルト挿通孔１７Ｃ〜１７Ｇを穿設することもできる。 Therefore, in the vibration control device 11, the angle members 17 and 20 constituting the lower column members 16 and 19 can be formed of generally commercially available angle steel (angle steel). Further, the angle members 17 and 20 can be cut to a predetermined length at the site, and a plurality of bolt insertion holes 17C to 17G can be bored.

Further, the upper reinforcing plates 38 and 40 can increase the strength of the upper transmitting member 28. Therefore, the lower reinforcing plates 22 and 24 can prevent the lower column members 16 and 19 from tilting with respect to the lower horizontal member 2. Further, the upper reinforcing plates 38 and 40 can prevent the upper column members 32 and 35 from tilting with respect to the upper horizontal member 3. As a result, the load due to vibration can be directly applied to each damper 46, and the damping performance can be improved.
