Description

この発明は、照明柱、標識柱、信号柱等の柱状構造物、建物等の建築構造物（以下纏めて、構造物と略す場合がある。）、又は機器類のベースプレートをその下方の基礎等から立ち上げたアンカーボルトとナットとで固定してなる、構造物、機器類の脚部制振構造の技術分野に属する。 In the present invention, a columnar structure such as an illumination pillar, a sign pillar, a signal pillar, a building structure such as a building (hereinafter, may be collectively abbreviated as a structure), or a base plate of equipment is used as a foundation below the structure. It belongs to the technical field of leg vibration damping structure of structures and equipment, which is fixed by anchor bolts and nuts launched from.

従来から構造物の脚部（柱脚部）を構成するベースプレートにゴム材等の制振部材を取りつけて振動の吸収効果を得る技術は、種々開示されている（例えば、特許文献１〜４を参照）。前記ゴム材等の制振部材は、前記特許文献１〜４に示したように、アンカーボルトを介して挟み付ける構成が構造上シンプルで、機械的に実施できることから近年でもよく採用されている。 Conventionally, various techniques for obtaining a vibration absorbing effect by attaching a vibration damping member such as a rubber material to a base plate constituting a leg portion (column base portion) of a structure have been disclosed (for example, Patent Documents 1 to 4). reference). As shown in Patent Documents 1 to 4, the vibration damping member such as a rubber material is often used in recent years because the structure of sandwiching the vibration damping member via anchor bolts is structurally simple and can be mechanically implemented.

特開平０７−２８６３６２号公報Japanese Unexamined Patent Publication No. 07-286362 特開平１０−０２５７５９号公報Japanese Unexamined Patent Publication No. 10-0257559 特開平１０−２９９０８１号公報Japanese Unexamined Patent Publication No. 10-299081 特開２００６−２３３４８８号公報Japanese Unexamined Patent Publication No. 2006-233488

しかし、前記アンカーボルトを介して挟み付ける構成は、前記特許文献１の図１を例に説明すると、前記制振部材４がナット５の締め付け力（アンカーボルト３の軸力）により経時的に劣化、損傷する等して制振効果が小さくなるという解決するべき課題があった。 However, in the configuration of sandwiching the anchor bolts, the vibration damping member 4 deteriorates with time due to the tightening force of the nut 5 (axial force of the anchor bolt 3), to explain using FIG. 1 of Patent Document 1 as an example. There was a problem to be solved that the damping effect was reduced due to damage.

また、例えば橋や道路に設置される照明柱、標識柱、信号柱等の柱状構造物においては、橋梁や道路を車両が通行することによって生じる振動（交通振動）が前記柱状構造物のベースプレートから伝わり疲労破壊に繋がる虞があった。風等の水平力を受けると（カルマン）渦が発生するが、この渦の周期と柱状構造物の固有周期とが一致すると共振現象、ひいては渦励振が起こる。この渦励振が柱状構造物に作用すると疲労破壊に繋がる虞もあった。 Further, in a columnar structure such as a lighting column, a sign column, a signal column, etc. installed on a bridge or a road, vibration (traffic vibration) generated by a vehicle passing through the bridge or the road is generated from the base plate of the columnar structure. There was a risk that it would be transmitted and lead to fatigue destruction. When a horizontal force such as wind is received, a (Karman) vortex is generated, and when the period of this vortex and the natural period of the columnar structure match, a resonance phenomenon occurs, and eventually vortex excitation occurs. If this vortex excitation acts on the columnar structure, it may lead to fatigue fracture.

本発明は、上記した背景技術の課題に鑑みて案出されたものであり、その目的とするところは、前記ナットの締め付け力（前記アンカーボルトの軸力）を制御可能な拘束金物を用いることにより、前記制振部材の制振効果をより長く保持できる、構造物、機器類の脚部制振構造を提供することにある。 The present invention has been devised in view of the above-mentioned problems of the background art, and an object of the present invention is to use a restraining metal fitting capable of controlling the tightening force of the nut (axial force of the anchor bolt).

本発明によれば、以下の効果を奏する。
（１）基礎等に反力を得てナットの締め付け力（アンカーボルトの軸力）に抵抗可能な立ち上がり部を備えた拘束金物を用いて実施するので、前記立ち上がり部の内側高さを設計変更することにより、ナットの締め付け力（アンカーボルトの軸力）を自在に制御できる。よって、制振部材を過剰（過度）に圧縮しないように実施できる等、従来技術と比し、
制振部材の制振効果をより長く保持することができる。これに伴い、ベースプレートに設けた制振部材が適度に変形して（過剰に変形しないで）振動エネルギーを吸収することで振動の振幅を小さくして疲労破壊を防ぐ等、柱状構造物の交通振動対策や渦励振対策としても好適な脚部制振構造を実現することができる。
（２）もとより、照明柱、標識柱、信号柱等の柱状構造物の柱に飛来物や車両の衝突があった際に、制振部材が変形して振動エネルギーを吸収することで当該柱の損傷を緩和することもできる。
（３）制振部材の制振効果をより長く保持できることに伴い、メンテナンスフィーを軽減できる等、経済性に優れている。機械的な作業で確実に構築できるので、熟練工を必要としない等、施工性にも優れている。
（４）制振部材の大部分を拘束金物で覆って実施できるので、紫外線による制振部材の劣化・損傷の防止に寄与できる。また、アンカーボルトが挿通される貫通孔を広げてアンカーボルトへの接触面積を広くすることで制振部材の劣化・損傷を緩和することもできる。
（５）その他、使用する制振部材の厚み、ベースプレートの板厚を実測してから拘束金物の高さを決定し、製造することで板厚公差を吸収できる等、所望の制振効果を確実に実現できる。 According to the present invention, the following effects are obtained.
(1) Since it is carried out using a restraining hardware equipped with a rising portion that can resist the tightening force of the nut (axial force of the anchor bolt) by obtaining a reaction force on the foundation, etc., the design change of the inner height of the rising portion By doing so, the tightening force of the nut (axial force of the anchor bolt) can be freely controlled. Therefore, compared with the conventional technology, the damping member can be implemented so as not to be excessively compressed.
The damping effect of the damping member can be maintained for a longer period of time. Along with this, the vibration damping member provided on the base plate is appropriately deformed (without excessive deformation) to absorb vibration energy, thereby reducing the amplitude of vibration and preventing fatigue failure. It is possible to realize a leg vibration damping structure that is also suitable as a countermeasure or a vortex excitation countermeasure.
(2) Of course, when a flying object or a vehicle collides with a pillar of a columnar structure such as a lighting pillar, a sign pillar, or a signal pillar, the vibration damping member deforms to absorb vibration energy of the pillar. Damage can also be mitigated.
(3) Since the damping effect of the damping member can be maintained for a longer period of time, the maintenance fee can be reduced, which is excellent in economic efficiency. Since it can be constructed reliably by mechanical work, it does not require skilled workers and has excellent workability.
(4) Since most of the damping member can be covered with a restraining metal fitting, it can contribute to the prevention of deterioration and damage of the damping member due to ultraviolet rays. Further, deterioration / damage of the vibration damping member can be alleviated by widening the through hole through which the anchor bolt is inserted to widen the contact area with the anchor bolt.
(5) In addition, the desired damping effect can be ensured by measuring the thickness of the damping member to be used and the thickness of the base plate, determining the height of the restraint hardware, and absorbing the plate thickness tolerance by manufacturing. Can be realized.

次に、本発明に係る脚部制振構造および同構造に用いる拘束金物の実施例を図面に基づいて説明する。なお、実施例１〜実施例７（図１〜図１５）では、照明柱、標識柱、信号柱等の柱状構造物に本発明を適用した場合について説明する。 Next, an example of the leg vibration damping structure according to the present invention and the restraint hardware used for the structure will be described with reference to the drawings. In Examples 1 to 7 (FIGS. 1 to 15), a case where the present invention is applied to a columnar structure such as an illumination column, a sign column, and a signal column will be described.

本発明に係る柱状構造物の脚部制振構造は、図１〜図４に示したように、照明柱等の柱状構造物１のベースプレート１１をその下方の基礎１０から立ち上げたアンカーボルト２とナット３とで固定してなる。
前記ベースプレート１１と、前記ベースプレート１１の上面（及び／又は下面）に設けた制振部材４とが前記アンカーボルト２で串刺し状に貫通された状態で、前記制振部材４の変形を抑制する拘束金物５の水平部５２を介在させてナット３で固定されている。
前記拘束金物５は、前記アンカーボルト２が挿通される貫通孔５２ａを有する水平部５２と前記水平部５２を支持する立ち上がり部５１とを備えている。
ちなみに、図中の符号１２は補強リブであり、前記ベースプレート１１の上面に、前記ベースプレート１１と前記柱状構造物１の脚部とのいずれにも直角となる方向に溶接によりバランスよく複数枚（図示例では四方に１枚ずつ計４枚）設けられている。 As shown in FIGS. 1 to 4, the leg vibration damping structure of the columnar structure according to the present invention is an anchor bolt 2 in which the base plate 11 of the columnar structure 1 such as a lighting column is raised from the foundation 10 below the base plate 11. And nut 3 are fixed.
A restraint that suppresses deformation of the vibration damping member 4 while the base plate 11 and the vibration damping member 4 provided on the upper surface (and / or lower surface) of the base plate 11 are penetrated in a skewered manner by the anchor bolts 2. It is fixed by a nut 3 with a horizontal portion 52 of the hardware 5 interposed therebetween.
The restraint metal fitting 5 includes a horizontal portion 52 having a through hole 52a through which the anchor bolt 2 is inserted, and a rising portion 51 that supports the horizontal portion 52.
By the way, reference numeral 12 in the drawing is a reinforcing rib, and a plurality of sheets are well-balanced by welding on the upper surface of the base plate 11 in a direction perpendicular to both the base plate 11 and the legs of the columnar structure 1 (FIG. In the example, one sheet is provided on each side, for a total of four sheets).

前記基礎１０は、一例として、道路脇のコンクリート基礎を示している。
前記アンカーボルト２は、下端部が基礎１０に埋設され、上端部が基礎１０の天端から略鉛直に立ち上がる構成で、平面視で略正方形の頂点に相当する配置に計４本立設されている。図示例に係る前記４本のアンカーボルト２は、前記ベースプレート１１の各コーナー部近傍位置に穿設された計４つの貫通孔１１ａを貫通可能な配置に立設されている。 The foundation 10 shows a concrete foundation on the side of a road as an example.
The lower end of the anchor bolt 2 is embedded in the foundation 10, and the upper end of the anchor bolt 2 rises substantially vertically from the top of the foundation 10, and a total of four anchor bolts 2 are erected in an arrangement corresponding to the apex of a substantially square in a plan view. .. The four anchor bolts 2 according to the illustrated example are erected in an arrangement capable of penetrating a total of four through holes 11a formed in the vicinity of each corner of the base plate 11.

前記ベースプレート１１は、前記柱状構造物１の脚部の下端と溶接等の接合手段で一体化されている。このベースプレート１１は、本実施例では板厚３４ｍｍの平面視略正方形状で実施され、前記４本のアンカーボルト２の上端部に対し、前記４つの貫通孔１１ａをそれぞれ位置合わせして挿入することにより前記基礎１０の上面に略水平に載置されている。 The base plate 11 is integrated with the lower end of the leg portion of the columnar structure 1 by a joining means such as welding. In this embodiment, the base plate 11 is implemented in a substantially square shape in a plan view having a plate thickness of 34 mm, and the four through holes 11a are respectively aligned and inserted into the upper ends of the four anchor bolts 2. Is placed substantially horizontally on the upper surface of the foundation 10.

また、前記ベースプレート１１の各コーナー部の上面には、前記制振部材４が、略中央部に設けた貫通孔４ａに前記アンカーボルト２の上端部を挿通させた状態で載置されている。図示例に係る制振部材４は、前記ベースプレート２のコーナー部に納まりやすく、かつ、使用する拘束金物５に覆われるほどに小さい平面視多角形状で、均等厚（一例として８ｍｍ）に成形した所望の減衰効果を発揮するフラット型のゴム材で実施されている。 Further, on the upper surface of each corner portion of the base plate 11, the vibration damping member 4 is placed in a state where the upper end portion of the anchor bolt 2 is inserted into a through hole 4a provided in a substantially central portion. The vibration damping member 4 according to the illustrated example has a polygonal shape in a plan view that is easy to fit in the corner portion of the base plate 2 and is small enough to be covered with the restraint metal fitting 5 to be used, and is desired to be molded to an uniform thickness (8 mm as an example). It is carried out with a flat type rubber material that exerts the damping effect of.

前記拘束金物５は、制振部材４の変形を抑制（拘束）するための金属製の金物であり、
前記４つの制振部材４の上方にそれぞれ、やはり前記アンカーボルト２により串刺し状に貫通されて位置決めされている。
前記拘束金物５は、図３、図４にも示したように、２種類成形され、ともに前記水平部５２と、前記ベースプレート１１の外側から立ち上がり前記水平部５２を支持する立ち上がり部５１とからなる。より詳しく説明すると、図示例に係る拘束金物５は、前記ベースプレート１１のコーナー部の外側に沿うように平面視直角２方向から立ち上がる２つの立ち上がり部５１、５１と、前記立ち上がり部５１、５１と連設されて前記ベースプレート１１のコーナー部を覆うように折り曲げ成形される水平部５２とからなる自立可能な構成で実施されている。そして、前記水平部５２の略中央部に穿設した貫通孔５２ａに前記アンカーボルト２の上端部を貫通させた状態で、前記水平部５２が前記制振部材４の直上に位置決めされる。
ちなみに前記拘束金物５の大きさは、一例として、図３、図４の符号Ｓ１が４１．５ｍｍ、Ｓ２が４７．５ｍｍ、Ｓ３が１５２ｍｍ、Ｓ４が１２７ｍｍで実施されている。板厚は６ｍｍで折り曲げ成形されている。 The restraint metal fitting 5 is a metal metal fitting for suppressing (constraining) the deformation of the vibration damping member 4.
Each of the four vibration damping members 4 is positioned above the four vibration damping members 4 by being penetrated in a skewered manner by the anchor bolts 2.
As shown in FIGS. 3 and 4, the restraint metal fitting 5 is molded in two types, and both includes the horizontal portion 52 and a rising portion 51 that rises from the outside of the base plate 11 and supports the horizontal portion 52. .. More specifically, the restraint metal fitting 5 according to the illustrated example is connected to two rising portions 51, 51 rising from two directions perpendicular to the plan view along the outside of the corner portion of the base plate 11, and the rising portions 51, 51. It is implemented in a self-supporting configuration including a horizontal portion 52 that is provided and bent so as to cover the corner portion of the base plate 11. Then, the horizontal portion 52 is positioned directly above the vibration damping member 4 in a state where the upper end portion of the anchor bolt 2 is passed through the through hole 52a formed in the substantially central portion of the horizontal portion 52.
Incidentally, as an example, the size of the restraint metal fitting 5 is 41.5 mm for reference numeral S1 in FIGS. 3 and 4, 47.5 mm for S2, 152 mm for S3, and 127 mm for S4. The plate thickness is 6 mm and it is bent and molded.

すなわち、本実施例では、前記ベースプレート１１の板厚が３４ｍｍ、前記制振部材４の厚みが８ｍｍ、の合わせて４２ｍｍであるのに対し、前記拘束金物５の内側高さ（Ｓ１）が４１．５ｍｍである。よって、図１Ｂに示したように、前記拘束金物５の立ち上がり部５１を前記基礎１０の上面に接地させると、同時に、前記制振部材４の直上に位置する前記拘束金物５の水平部５２が前記制振部材４を下方へ０．５ｍｍほど押さえつけることになる。
この状態で、前記ナット３の締め付け作業を前記拘束金物５の水平部５２の上面に当接するまで行うことにより、また、前記アンカーボルト２の本数に応じて繰り返し行うことにより、前記アンカーボルト２に順に串刺し状に貫通されたベースプレート１１、制振部材４、および拘束金物５（の水平部５２）が基礎１０の上面に整列された状態で固定される。 That is, in this embodiment, the thickness of the base plate 11 is 34 mm and the thickness of the vibration damping member 4 is 8 mm, which is 42 mm in total, whereas the inner height (S1) of the restraint metal fitting 5 is 41. It is 5 mm. Therefore, as shown in FIG. 1B, when the rising portion 51 of the restraint metal fitting 5 is grounded on the upper surface of the foundation 10, at the same time, the horizontal portion 52 of the restraint metal fitting 5 located directly above the vibration damping member 4 is formed. The vibration damping member 4 is pressed downward by about 0.5 mm.
In this state, the nut 3 is tightened to the anchor bolt 2 by repeating the tightening work until it comes into contact with the upper surface of the horizontal portion 52 of the restraint metal fitting 5 and repeatedly according to the number of the anchor bolts 2. The base plate 11, the vibration damping member 4, and the restraint metal fitting 5 (horizontal portion 52), which are sequentially penetrated in a skewered shape, are fixed in a state of being aligned on the upper surface of the foundation 10.

なお、本実施例では、前記拘束金物５の水平部５２が前記制振部材４を下方へ０．５ｍｍほど押さえつける構成で実施しているが、この数値は所望の制振効果（減衰効果）等を勘案した構造設計に応じて適宜設計変更可能である。押さえつけず、単に接する構成で実施することもできる。
また、前記ベースプレート１１、制振部材４、又は拘束金物５の大きさは、もちろん前記に限定されず適宜設計変更可能である。前記拘束金物５の水平部５２の平面形状は、前記制振部材４の平面形状よりも一回り大きい相似形状（矩形状の角部を適宜直線状に切除した多角形状）で実施しているが、適宜設計変更可能である。
例えば、図１２、図１３および図１４、図１５に係る脚部制振構造は、拘束金物８、８’を一体成型品（鋳物）で実施している。この一体成型品である拘束金物８、８’は、折り曲げ成形品である前記拘束金物５と比し、より緻密な構造を呈する。
具体的に、図１２、図１３に係る拘束金物８は、水平部８２の縁を下向きに僅かにカーブさせてベースプレート１１の上面に当接可能な垂下部８２ｂを備えるほか、ナット３の位置決めを容易ならしめる凹部８２ｃも備えている。前記垂下部８２ｂの突出量は、制振部材４の厚さ未満に設定される。すなわち、前記垂下部８２ｂの先端が、ナット３を締め付けたときベースプレート１１に接しない構成とされる。ちなみに図中の符号８１は立ち上がり部、符号８２ａは貫通孔、符号８２ｄは前記凹部８２ｃに雨水等が溜まることを防ぐ水切り溝を示している。
図１４、図１５の拘束金物８’は、寸法等の形態は若干相違するものの前記拘束金物８の垂下部８２ｂに相当する垂下部８２ｂ’や凹部８２ｃに相当する凹部８２ｃ’を備えている。加えて、水平部８２’の下面における貫通孔８２ａ’周りにリング状の突出部８２ｄ’を形成している。前記突出部８２ｄ’の突出量は、制振部材４の厚さ未満に設定され、前記垂下部８２ｂ’の突出量は、前記突出部８２ｄ’の突出量以下に設定される。すなわち、前記突出部８２ｄ’および前記垂下部８２ｂ’の先端が、ナット３を締め付けたときベースプレート１１に接しない構成とされる。ちなみに図中の符号８１’は立ち上がり部、符号８２ｅ’は前記凹部８２ｃ’に雨水等が溜まることを防ぐ水切り溝を示している。
以下に説明する実施例２〜７についても、折り曲げ成形品である拘束部材５に代えて一体成型品である拘束金物８、８’で実施できる。 In this embodiment, the horizontal portion 52 of the restraint hardware 5 presses the vibration damping member 4 downward by about 0.5 mm, but this numerical value is a desired vibration damping effect (damping effect) and the like. The design can be changed as appropriate according to the structural design in consideration of. It is also possible to carry out with a configuration that simply touches without pressing down.
Further, the size of the base plate 11, the vibration damping member 4, or the restraint metal fitting 5 is not limited to the above, and the design can be changed as appropriate. The plane shape of the horizontal portion 52 of the restraint metal fitting 5 is a similar shape (a polygonal shape in which the rectangular corner portion is appropriately cut into a straight line), which is one size larger than the plane shape of the vibration damping member 4. , The design can be changed as appropriate.
For example, in the leg vibration damping structure according to FIGS. 12, 13, 14 and 15, the restraining metal fittings 8 and 8'are implemented as integrally molded products (castings). The restraint metal fittings 8 and 8', which are integrally molded products, exhibit a more precise structure than the restraint metal fittings 5 which are bend-molded products.
Specifically, the restraint metal fitting 8 according to FIGS. 12 and 13 includes a hanging portion 82b capable of slightly curving the edge of the horizontal portion 82 downward and abutting on the upper surface of the base plate 11, and also positions the nut 3. It also has a recess 82c for easy leveling. The amount of protrusion of the hanging portion 82b is set to be less than the thickness of the vibration damping member 4. That is, the tip of the hanging portion 82b does not come into contact with the base plate 11 when the nut 3 is tightened. Incidentally, reference numeral 81 in the drawing indicates a rising portion, reference numeral 82a indicates a through hole, and reference numeral 82d indicates a draining groove for preventing rainwater or the like from accumulating in the recess 82c.
The restraint metal fittings 8'of FIGS. 14 and 15 are provided with a hanging portion 82b'corresponding to the hanging portion 82b and a recessed portion 82c' corresponding to the recessed portion 82c, although the forms such as dimensions are slightly different. In addition, a ring-shaped protrusion 82d'is formed around the through hole 82a' on the lower surface of the horizontal portion 82'. The protruding amount of the protruding portion 82d'is set to be less than the thickness of the vibration damping member 4, and the protruding amount of the hanging portion 82b'is set to be equal to or less than the protruding amount of the protruding portion 82d'. That is, the tip of the protruding portion 82d'and the tip of the hanging portion 82b'do not come into contact with the base plate 11 when the nut 3 is tightened. Incidentally, reference numeral 81'in the figure indicates a rising portion, and reference numeral 82e'indicates a drainage groove for preventing rainwater or the like from accumulating in the recess 82c'.
Examples 2 to 7 described below can also be carried out with restraint hardware 8 and 8'which are integrally molded products instead of the restraint member 5 which is a bent molded product.

したがって、この実施例１に係る柱状構造物の脚部制振構造によれば、以下の効果を奏する。
（１）基礎１０に反力を得てナット３の締め付け力（アンカーボルト２の軸力）に抵抗可能な立ち上がり部５１を備えた拘束金物５を用いて実施するので、前記立ち上がり部５１の内側高さ（Ｓ１）を調整することにより、ナット３の締め付け力（アンカーボルト２の軸力）を自在に制御できる。
よって、制振部材４を過剰（過度）に圧縮しないように実施できる等、従来技術と比し、制振部材４の制振効果をより長く保持することができる。これに伴い、ベースプレートに設けた制振部材が適度に変形して（過剰に変形しないで）振動エネルギーを吸収することで振動の振幅を小さくして疲労破壊を防ぐ等、柱状構造物の交通振動対策や渦励振対策としても好適な脚部制振構造を実現することができる。
（２）もとより、照明柱、標識柱、信号柱等の柱状構造物の柱に飛来物や車両の衝突があった際に、制振部材４が変形して振動エネルギーを吸収することで当該柱の損傷を緩和することもできる。
（３）制振部材４の制振効果をより長く保持できることに伴い、メンテナンスフィーを軽減できる等、経済性に優れている。機械的な作業で確実に構築できるので、熟練工を必要としない等、施工性にも優れている。
（４）制振部材４の大部分を拘束金物５で覆って実施できるので、紫外線による制振部材４の劣化・損傷の防止に寄与する。また、アンカーボルト２が挿通される貫通孔４ａを広げてアンカーボルト２への接触面積を広くすることで制振部材４の劣化・損傷を緩和することもできる。
（５）その他、使用する制振部材の厚み、ベースプレートの板厚を実測してから拘束金物の高さを決定し、製造することで板厚公差を吸収できる等、所望の制振効果を確実に実現できる。
（６）前記拘束金物５の代わりに前記拘束金物８で実施すると、前記垂下部８２の下向きの突出効果により、より確実に制振部材４を過剰に圧縮しないように実施できる。具体的には、柱状構造物１に風荷重等が載荷されることによりベースプレート１１にモーメントが生じ、ベースプレート１１上の制振部材４に過度の圧縮荷重が生じた場合、当該圧縮荷重を前記垂下部８２が負担することで、制振部材４の劣化、損傷を未然に防止できる。また、より確実に制振部材４を覆うことができるので、紫外線による制振部材４の劣化・損傷の防止に更に寄与できる。
また、前記拘束金物５の代わりに前記拘束金物８’で実施すると、前記垂下部８２’よりも突出寸法が長い前記リング状の突出部８２ｄ’の下向きの突出効果により、より確実に制振部材４を過剰に圧縮しないように実施できる。具体的には、柱状構造物１に風荷重等が載荷されることによりベースプレート１１にモーメントが生じ、ベースプレート１１上の制振部材４に過度の圧縮荷重が生じた場合、当該圧縮荷重を前記リング状の突出部８２ｄ’が負担することで、制振部材４の劣化、損傷を未然に防止できる。また、前記垂下部８２’が制振部材４を覆うことができるので、紫外線による制振部材４の劣化・損傷の防止に更に寄与できる。この拘束金物８’によれば、圧縮荷重を受ける部位が、ナット３締め付け部近傍のリング状の突出部８２ｄ’であるため、垂下部８２で受ける拘束金物８と比し、応力集中が起こりにくく、より効果的に圧縮荷重を負担できる利点がある。 Therefore, according to the leg vibration damping structure of the columnar structure according to the first embodiment, the following effects are obtained.
(1) Since the restraint metal fitting 5 provided with the rising portion 51 capable of obtaining a reaction force on the foundation 10 and resisting the tightening force of the nut 3 (the axial force of the anchor bolt 2) is used, the inside of the rising portion 51 is used. By adjusting the height (S1), the tightening force of the nut 3 (axial force of the anchor bolt 2) can be freely controlled.
Therefore, the vibration damping effect of the vibration damping member 4 can be maintained for a longer period of time as compared with the conventional technique, for example, the vibration damping member 4 can be implemented so as not to be excessively (excessively) compressed. Along with this, the vibration damping member provided on the base plate is appropriately deformed (without excessive deformation) to absorb vibration energy, thereby reducing the amplitude of vibration and preventing fatigue failure. It is possible to realize a leg vibration damping structure that is also suitable as a countermeasure or a vortex excitation countermeasure.
(2) Of course, when a flying object or a vehicle collides with a pillar of a columnar structure such as a lighting pillar, a sign pillar, or a signal pillar, the vibration damping member 4 is deformed to absorb vibration energy, thereby absorbing the pillar. Damage can also be mitigated.
(3) Since the damping effect of the damping member 4 can be maintained for a longer period of time, the maintenance fee can be reduced, which is excellent in economic efficiency. Since it can be constructed reliably by mechanical work, it does not require skilled workers and has excellent workability.
(4) Since most of the vibration damping member 4 can be covered with the restraint metal fitting 5, it contributes to the prevention of deterioration / damage of the vibration damping member 4 due to ultraviolet rays. Further, deterioration / damage of the vibration damping member 4 can be alleviated by widening the through hole 4a through which the anchor bolt 2 is inserted to widen the contact area with the anchor bolt 2.
(5) In addition, the desired damping effect can be ensured by measuring the thickness of the damping member to be used and the thickness of the base plate, determining the height of the restraint hardware, and absorbing the plate thickness tolerance by manufacturing. Can be realized.
(6) When the restraint metal fitting 8 is used instead of the restraint metal fitting 5, the damping member 4 can be more reliably prevented from being excessively compressed due to the downward protrusion effect of the hanging portion 82. Specifically, when a moment is generated on the base plate 11 due to a wind load or the like being loaded on the columnar structure 1, and an excessive compressive load is generated on the vibration damping member 4 on the base plate 11, the compressed load is drooped. By bearing the burden on the portion 82, deterioration and damage of the vibration damping member 4 can be prevented. Further, since the vibration damping member 4 can be covered more reliably, it can further contribute to the prevention of deterioration / damage of the vibration damping member 4 due to ultraviolet rays.
Further, when the restraint metal fitting 8'is used instead of the restraint metal fitting 5, the damping member is more reliably vibration-damped due to the downward protrusion effect of the ring-shaped protrusion 82d', which has a longer protrusion dimension than the hanging portion 82'. It can be carried out so as not to excessively compress 4. Specifically, when a moment is generated on the base plate 11 due to a wind load or the like being loaded on the columnar structure 1, and an excessive compressive load is generated on the vibration damping member 4 on the base plate 11, the compressed load is applied to the ring. By bearing the shape of the protruding portion 82d', deterioration and damage of the vibration damping member 4 can be prevented. Further, since the hanging portion 82'can cover the vibration damping member 4, it can further contribute to the prevention of deterioration and damage of the vibration damping member 4 due to ultraviolet rays. According to this restraint metal fitting 8', since the portion that receives the compressive load is the ring-shaped protrusion 82d'near the nut 3 tightening portion, stress concentration is less likely to occur as compared with the restraint metal fitting 8 that is received by the hanging portion 82. , Has the advantage of being able to bear the compressive load more effectively.

図５は、実施例２に係る柱状構造物の脚部制振構造を示している。
この実施例２に係る柱状構造物の脚部制振構造は、上記実施例１と比し、前記制振部材４、及び前記拘束金物５の平面形状が異なる点が相違する（図１Ｂと図５Ｂとを対比して参照）。
よって、この実施例２に係る柱状構造物の脚部制振構造は、上記実施例１と同様に、基礎１０に反力を得てナット３の締め付け力（アンカーボルト２の軸力）に抵抗可能な立ち上がり部５１を備えた拘束金物５を用いて実施することに何ら変わりはない。
したがって、上記実施例１と同様の作用効果を奏する（前記段落［００２３］参照）。 FIG. 5 shows a leg vibration damping structure of the columnar structure according to the second embodiment.
The leg damping structure of the columnar structure according to the second embodiment is different from the first embodiment in that the planar shapes of the damping member 4 and the restraint metal fitting 5 are different (FIGS. 1B and FIG. See in comparison with 5B).
Therefore, the leg damping structure of the columnar structure according to the second embodiment obtains a reaction force on the foundation 10 and resists the tightening force of the nut 3 (axial force of the anchor bolt 2) as in the first embodiment. There is no difference in carrying out using the restraint hardware 5 provided with the possible rising portion 51.
Therefore, it has the same effect as that of the first embodiment (see the paragraph [0023] above).

図６は、実施例３に係る柱状構造物の脚部制振構造を示している。
この実施例３に係る柱状構造物の脚部制振構造は、上記実施例１と比し、前記ベースプレート１１、制振部材４、及び前記拘束金物５の平面形状が異なる点が相違する（図１Ｂと図６Ｂとを対比して参照）。 FIG. 6 shows a leg vibration damping structure of the columnar structure according to the third embodiment.
The leg damping structure of the columnar structure according to the third embodiment is different from the first embodiment in that the plane shapes of the base plate 11, the damping member 4, and the restraining metal fitting 5 are different (FIG. 3). Refer to 1B in comparison with FIG. 6B).

よって、この実施例３に係る柱状構造物の脚部制振構造は、上記実施例１と同様に、基礎１０に反力を得てナット３の締め付け力（アンカーボルト２の軸力）に抵抗可能な立ち上がり部５１を備えた拘束金物５を用いて実施することに何ら変わりはない。
したがって、上記実施例１と同様の作用効果を奏する（前記段落［００２３］参照）。 Therefore, the leg damping structure of the columnar structure according to the third embodiment obtains a reaction force on the foundation 10 and resists the tightening force of the nut 3 (axial force of the anchor bolt 2) as in the first embodiment. There is no difference in carrying out using the restraint hardware 5 provided with the possible rising portion 51.
Therefore, it has the same effect as that of the first embodiment (see the paragraph [0023] above).

図７は、実施例４に係る柱状構造物の脚部制振構造を示している。
この実施例４に係る柱状構造物の脚部制振構造は、上記実施例１の構成に加え、さらに、前記ベースプレート１１の下面に、前記ベースプレート１１と略同じ面積を有する制振部材（ゴム材）６を付設している点が相違する（図１Ａと図７Ａとを対比して参照）。これに伴い、前記拘束金物５の立ち上がり部５１の高さを前記制振部材６の厚み分だけ高く設定している。ちなみに、この制振部材６にもアンカーボルト２を貫通させるための挿通孔が４箇所穿設されている。 FIG. 7 shows a leg vibration damping structure of the columnar structure according to the fourth embodiment.
The leg vibration damping structure of the columnar structure according to the fourth embodiment has a vibration damping member (rubber material) having substantially the same area as the base plate 11 on the lower surface of the base plate 11 in addition to the configuration of the first embodiment. ) 6 is attached (see FIG. 1A and FIG. 7A in comparison). Along with this, the height of the rising portion 51 of the restraint hardware 5 is set higher by the thickness of the vibration damping member 6. Incidentally, the vibration damping member 6 is also provided with four insertion holes for penetrating the anchor bolt 2.

よって、この実施例４に係る柱状構造物の脚部制振構造は、上記実施例１と同様に、基礎１０に反力を得てナット３の締め付け力（アンカーボルト２の軸力）に抵抗可能な立ち上がり部５１を備えた拘束金物５を用いて実施することに何ら変わりはない。したがって、上記実施例１と同様の作用効果を奏する（前記段落［００２３］参照）。加えて、前記制振部材６を追加した効果により、上記実施例１よりも高い減衰効果を発揮することができる。 Therefore, the leg damping structure of the columnar structure according to the fourth embodiment obtains a reaction force on the foundation 10 and resists the tightening force of the nut 3 (axial force of the anchor bolt 2) as in the first embodiment. There is no difference in carrying out using the restraint hardware 5 provided with the possible rising portion 51. Therefore, it has the same effect as that of the first embodiment (see the paragraph [0023] above). In addition, due to the effect of adding the vibration damping member 6, a higher damping effect than that of the first embodiment can be exhibited.

図８は、実施例５に係る柱状構造物の脚部制振構造を示している。
この実施例５に係る柱状構造物の脚部制振構造は、上記実施例４の構成に加え、さらに、前記制振部材６の下面に、前記制振部材６よりも一回り広い面積を有する下部拘束プレート７を付設している点が相違する（図７と図８とを対比して参照）。ちなみに、前記下部拘束プレート７は、その上面に制振部材６を安定した状態で載置することが可能な金属製のプレートであり、この下部拘束プレート７にもアンカーボルト２を貫通させるための挿通孔が４箇所穿設されている。 FIG. 8 shows a leg vibration damping structure of the columnar structure according to the fifth embodiment.
In addition to the configuration of the fourth embodiment, the leg vibration damping structure of the columnar structure according to the fifth embodiment has an area slightly larger than that of the vibration damping member 6 on the lower surface of the vibration damping member 6. The difference is that the lower restraint plate 7 is attached (see FIG. 7 and FIG. 8 in comparison). Incidentally, the lower restraint plate 7 is a metal plate on which the vibration damping member 6 can be placed in a stable state on the upper surface thereof, and the anchor bolt 2 is also allowed to penetrate through the lower restraint plate 7. Four insertion holes are drilled.

よって、この実施例５に係る柱状構造物の脚部制振構造は、上記実施例４と同様の作用効果を奏する（前記段落［００２８］参照）ことに加え、前記下部拘束プレート７を、（レベルが出ていない）基礎１０と制振部材６との間に介在させることにより、前記制振部材６を前記下部拘束プレート７上に隙間なく密着させて安定した状態で載置できるので、上記実施例４と比し、前記制振部材６、ひいては前記柱脚制振構造の制振効果をより確実に発揮させ得る構造を実現できる。例えば、レベルや建ちの調整をベースプレート１１の下方にナット等を用いて行うことがあるが（図示省略）、この場合、前記ベースプレート１１の下に制振部材６を安定した状態で載置するのに難渋するところ、前記制振部材６の下に下部拘束プレート７を設けることにより前記制振部材６を容易に安定した状態で載置できるので、特に効果的である。 Therefore, the leg damping structure of the columnar structure according to the fifth embodiment has the same effect as that of the fourth embodiment (see the paragraph [0028]), and the lower restraint plate 7 is (see). By interposing the vibration damping member 6 between the foundation 10 and the vibration damping member 6 (the level is not raised), the vibration damping member 6 can be placed on the lower restraint plate 7 in a stable state without any gaps. Compared with the fourth embodiment, it is possible to realize a structure capable of more reliably exerting the vibration damping effect of the vibration damping member 6, and by extension, the column base vibration damping structure. For example, the level and the building may be adjusted by using a nut or the like below the base plate 11 (not shown). In this case, the damping member 6 is placed under the base plate 11 in a stable state. However, it is particularly effective because the vibration damping member 6 can be easily placed in a stable state by providing the lower restraint plate 7 under the vibration damping member 6.

図９は、実施例６に係る柱状構造物の脚部制振構造を示している。
この実施例６に係る柱状構造物の脚部制振構造は、上記実施例１と比し、制振部材４（又は６）の設置部位が前記ベースプレート１１の上面（又は下面）である点が相違する（図１Ａと図９Ａとを対比して参照）。また、上記実施例４と比し、前記制振部材４がなく、前記ベースプレート１１の下面に設けた制振部材６のみで減衰効果を図る構成とした点が相違する（図７と図９とを対比して参照）。その他、拘束金物５の平面形状も若干相違する。 FIG. 9 shows the leg damping structure of the columnar structure according to the sixth embodiment.
The leg damping structure of the columnar structure according to the sixth embodiment is different from the first embodiment in that the damping member 4 (or 6) is installed on the upper surface (or lower surface) of the base plate 11. Different (see FIG. 1A and FIG. 9A in comparison). Further, as compared with the above-mentioned Example 4, the difference is that the damping effect is achieved only by the damping member 6 provided on the lower surface of the base plate 11 without the damping member 4 (FIGS. 7 and 9). See in comparison). In addition, the planar shape of the restraint hardware 5 is also slightly different.

よって、この実施例６に係る柱状構造物の脚部制振構造は、制振部材６の設置部位が前記ベースプレート１１の上面か又は下面かの違いはあるものの、上記実施例１と同様に、基礎１０に反力を得てナット３の締め付け力（アンカーボルト２の軸力）に抵抗可能な立ち上がり部５１を備えた拘束金物５を用いて実施することに何ら変わりはない。したがって、上記実施例１と同様の作用効果を奏する（前記段落［００２３］参照）。 Therefore, the leg damping structure of the columnar structure according to the sixth embodiment is similar to the first embodiment, although there is a difference in whether the damping member 6 is installed on the upper surface or the lower surface of the base plate 11. There is no difference in the implementation using the restraint metal fitting 5 provided with the rising portion 51 capable of obtaining a reaction force on the foundation 10 and resisting the tightening force of the nut 3 (the axial force of the anchor bolt 2). Therefore, it has the same effect as that of the first embodiment (see the paragraph [0023] above).

図１０、図１１は、実施例７に係る柱状構造物の脚部制振構造を示している。
この実施例７に係る柱状構造物の脚部制振構造は、上記実施例２と比し、拘束金物５に代えて段付きワッシャタイプの拘束金物９を用いている点が相違する（図５と図１０、図１１とを対比して参照）。その他、一回り小さい制振部材４を採用している点も相違する。
前記拘束金物９は、前記アンカーボルト２が挿通される貫通孔９ａを有する水平部９２と、前記ベースプレート１１を貫通して立ち上がり前記貫通孔９ａと連通する筒状（図示例では円筒形）の立ち上がり部９１とからなる。 10 and 11 show the leg damping structure of the columnar structure according to the seventh embodiment.
The leg damping structure of the columnar structure according to the seventh embodiment is different from the second embodiment in that a stepped washer type restraining metal fitting 9 is used instead of the restraining metal fitting 5 (FIG. 5). And FIGS. 10 and 11). Another difference is that the vibration damping member 4, which is one size smaller, is used.
The restraint metal fitting 9 rises through a horizontal portion 92 having a through hole 9a through which the anchor bolt 2 is inserted and the base plate 11, and rises in a tubular shape (cylindrical shape in the illustrated example) that communicates with the through hole 9a. It consists of a part 91.

この実施例７に用いるベースプレート１１と制振部材４は予め、前記拘束金物９の立ち上がり部９１ａが挿入可能な少し大きい貫通孔１１ａ、４ａを形成しておき、前記ベースプレート１１、制振部材４を順に位置決めし、前記貫通孔１１ａ、４ａ内にアンカーボルト２を串刺し状に貫通させると共に前記拘束金物９の立ち上がり部９１ａを挿入して立設し、後は上記各実施例と同様に水平部９２の上面でナット３の締め付け作業を行う要領で脚部制振構造を構築する。 The base plate 11 and the vibration damping member 4 used in the seventh embodiment are formed in advance with slightly larger through holes 11a and 4a into which the rising portion 91a of the restraint hardware 9 can be inserted, and the base plate 11 and the vibration damping member 4 are inserted. Positioning is performed in order, the anchor bolt 2 is penetrated into the through holes 11a and 4a in a skewered manner, and the rising portion 91a of the restraining metal fitting 9 is inserted and erected. The leg vibration damping structure is constructed in the same manner as the tightening work of the nut 3 on the upper surface of the above.

よって、この実施例７に係る柱状構造物の脚部制振構造は、拘束金物９の形態に違いはあるものの、前記拘束金物５と同様の機能を発揮する立ち上がり部９１と水平部９２とを備えていることに変わりはない。したがって、上記実施例２、即ち上記実施例１と同様の作用効果を奏する（前記段落［００２３］参照）。 Therefore, in the leg vibration damping structure of the columnar structure according to the seventh embodiment, although the form of the restraint metal fitting 9 is different, the rising portion 91 and the horizontal portion 92 that exhibit the same functions as the restraint metal fitting 5 are provided. There is no change in having. Therefore, it has the same effect as that of the second embodiment, that is, the first embodiment (see the paragraph [0023]).

以上、実施例を図面に基づいて説明したが、本発明は、図示例の限りではなく、その技術的思想を逸脱しない範囲において、当業者が通常に行う設計変更、応用のバリエーションの範囲を含むことを念のために言及する。
例えば、前記拘束金物８、８’は、一体成型品として鋳物を例に説明しているが、鋳物に限らず、３Ｄプリンターや削り出し加工により作製することもできる。また、前記アンカーボルト２は、４本で実施しているが勿論これに限定されず、サイズも含め適宜設計変更可能である。前記制振部材４、６はゴム材で実施しているがこれに限定されず、バネ材その他の弾性材でも同様に実施できる。 Although the examples have been described above based on the drawings, the present invention is not limited to the illustrated examples, and includes a range of design changes and application variations normally performed by those skilled in the art within a range that does not deviate from the technical idea thereof. I will mention it just in case.
For example, the restraint metal fittings 8 and 8'are described by taking a casting as an example as an integrally molded product, but the restraint metal fittings 8 and 8'are not limited to castings, but can also be manufactured by a 3D printer or a machined process. Further, the anchor bolt 2 is implemented with four bolts, but of course, the design is not limited to this, and the design can be changed as appropriate including the size. The vibration damping members 4 and 6 are made of a rubber material, but the present invention is not limited to this, and the same can be applied to a spring material or other elastic material.

さらに、図面（実施例１〜実施例７）では、本発明を柱状構造物の脚部制振構造に適用する場合について説明したが、本発明の適用対象はこれに限定されない。柱脚構造物に代えて、ベースプレート１１の上面にＨ形鋼等の鉄骨柱が立設される構成の建物等の建築構造物にも同様に適用できるし、又は、ベースプレート（ベース盤）１１の上面に取り付けプレートや絶縁プレートを介して設けられる構成の機器類にも同様に適用できる。 Further, in the drawings (Examples 1 to 7), a case where the present invention is applied to a leg vibration damping structure of a columnar structure has been described, but the application target of the present invention is not limited to this. It can be similarly applied to a building structure such as a building in which a steel frame column such as H-shaped steel is erected on the upper surface of the base plate 11 instead of the column base structure, or the base plate (base plate) 11 The same can be applied to equipment having a configuration provided on the upper surface via a mounting plate or an insulating plate.
