【産業上の利用分野】[Industrial applications]

本考案は、橋脚等の下部構造物と橋桁等の上部構造物との間に介装されるゴム 積層体等からなる支承材を予めせん断変形させる装置に関する。 The present invention relates to an apparatus for pre-shear-deforming a support member composed of a rubber laminate or the like interposed between a lower structure such as a bridge pier and an upper structure such as a bridge girder.

【0002】[0002]

【従来技術】[Prior art]

橋脚等の下部支持構造物にゴム支承材を介してコンクリートの橋桁等の上部構 造物を支承する場合、温度変化により構造物は伸縮し、特にコンクリートの橋桁 等は乾燥収縮やクリープ等により橋軸方向(前後水平方向)に収縮して上下構造 物間で互いに変位し、そのためゴム支承材は、橋軸方向にせん断変形される。 When an upper structure such as a concrete bridge girder is supported on a lower support structure such as a bridge pier via a rubber bearing material, the structure expands and contracts due to temperature changes, and especially the concrete bridge girder, etc. is dried and contracted by creep or the like. Direction (front-rear horizontal direction) and the upper and lower structures are displaced from each other, so that the rubber bearing member is sheared in the bridge axial direction.

【0003】 本来のゴム支承材機能である温度変化による橋桁伸縮変位を吸収するほかに上 述コンクリート収縮変化を吸収するためには、構造物の強化及びゴム支承材の高 さを高くする等の方法が必要である。In addition to absorbing the bridge girder expansion and contraction displacement due to temperature change, which is the original function of the rubber support material, in order to absorb the concrete shrinkage change, the structure is strengthened and the height of the rubber support material is increased. Need a way.

【0004】 しかしいずれにしても設計上の弊害が多くなり、またコストも高くなる。 そこでゴム支承材に予め構造物の変形方向と逆方向のせん断変形を与えておく 方法が従来より採用されており、そのためのせん断変形保持装置が種々提案され ている。However, in any case, there are many adverse effects on the design and the cost also increases. Therefore, a method of applying shear deformation to the rubber bearing material in the direction opposite to the deformation direction of the structure in advance has been conventionally used, and various shear deformation holding devices for that purpose have been proposed.

【0005】 例えば特開昭62-45803号公報に記載された例について図6および図7に基づき 説明する。 ゴム支承材01は、偏平な略立方体状のゴム層02の上面および下面に矩形の上部 金属板03と下部金属板04が一体に固着され、上下各金属板03,04の中央に係止突 起03aと04aがそれぞれ設けられている。An example described in Japanese Patent Laid-Open No. 62-45803 will be described with reference to FIGS. 6 and 7. The rubber support member 01 has a rectangular upper metal plate 03 and a lower metal plate 04 integrally fixed to the upper surface and the lower surface of a flat and substantially cubic rubber layer 02, and has locking projections at the centers of the upper and lower metal plates 03 and 04. Origins 03a and 04a are provided, respectively.

【0006】 このゴム支承材01の上下金属板03,04を係止突起03aと04aを利用して特別の 治具を用いて互いに前後に変位させゴム層02を予めせん断変形させておく。 かかる状態で下面板05および前後幅長のより短い上面板06とこれらを連結する 多数のリブ07とからなる金属製前部支承部材08を前記ゴム支承材01の前部に配置 し、同様に下面板09、前後幅長のより長い上面板010 およびリブ011 からなる金 属製後部支承部材012 をゴム支承材01の後部に配置し、両金属製支承部材08,01 2 によりゴム支承材01を挟み、ゴム支承材01の左右側方に配置された金属製連結 部材013 ,014 が前後金属製前部支承部材08,012 の左右端部どうしを連結し、 かつ左右金属製連結部材013 ,014 の前後端部をそれぞれボルト015 ,017 が貫 通し、ナット016 ,018 で螺合緊締される。The upper and lower metal plates 03, 04 of the rubber support member 01 are displaced back and forth with each other using a special jig by utilizing the locking projections 03a and 04a, and the rubber layer 02 is preliminarily sheared and deformed. In this state, a metal front support member 08 including a lower surface plate 05, an upper surface plate 06 having a shorter front-rear width, and a plurality of ribs 07 that connect them is arranged at the front portion of the rubber support member 01, and similarly. A metal rear support member 012 consisting of a bottom plate 09, a longer front plate 010 having a longer front-rear width and ribs 011 is arranged at the rear of the rubber support member 01, and the metal support members 08 and 01 2 are used to support the rubber support member 01. The metal connecting members 013, 014 arranged on the left and right sides of the rubber support member 01 sandwich the front and rear metal front supporting members 08, 012, and the left and right metal connecting members 013, Bolts 015 and 017 penetrate the front and rear ends of 014, respectively, and they are screwed and tightened with nuts 016 and 018.

【0007】 このようにしてゴム支承材01を前後から金属製支承部材08,012 が挟持し、両 金属製支承部材08,012 を左右の金属製連結部材013 ,014 が連結して前後のボ ルト015 ,017 、ナット016 ,018 により保持されると、ゴム支承材01をせん断 変形させていた治具を外し、橋脚等の下部構造物の上面に下部金属板04を固定し 、上部金属板03の上には橋桁等の上部構造物がコンクリートを打設することによ り形成される。In this way, the rubber support member 01 is sandwiched between the front and rear metal support members 08 and 012, and the two metal support members 08 and 012 are connected by the left and right metal connection members 013 and 014, respectively. When held by the bolts 015 and 017 and the nuts 016 and 018, the jig that shear-deformed the rubber support member 01 is removed, and the lower metal plate 04 is fixed to the upper surface of the lower structure such as the bridge pier. An upper structure such as a bridge girder is formed on the 03 by pouring concrete.

【0008】 コンクリートの養生期間を経過したのち左右方向に貫通保持したボルト015 , 017 を外し、金属製連結部材013 ,014 および金属製支承部材08,012 を取り除 く。 こうして予めせん断変形されたゴム支承材により上部構造物が支持される。After the concrete curing period has passed, the bolts 015 and 017 that are held through in the left and right direction are removed, and the metal connecting members 013 and 014 and the metal supporting members 08 and 012 are removed. In this way, the upper structure is supported by the rubber bearing material that has been shear-deformed in advance.

【解決しようとする課題】[Problems to be solved]

以上のように従来のゴム支承材01のせん断変形を保持する装置であると、特別 にゴム支承材01をせん断変形させる治具を必要とし、かつ保持装置がゴム支承材 01の周囲に大きく配設され、多くの部材を組合わせて構成されているので、大型 で重量が重くコスト高であり、構造も複雑で作業性も悪い。 As described above, the conventional device for holding the shear deformation of the rubber bearing member 01 requires a jig for specially shearing the rubber bearing member 01, and the holding device is widely arranged around the rubber bearing member 01. Since it is installed and constructed by combining many members, it is large, heavy and costly, and its structure is complicated and workability is poor.

【0010】 また予備せん断保持装置には、ゴム支承材01のせん断変形による元に戻ろうと する力が働いているので、保持装置をゴム支承材01から外す際に、再びゴム支承 材01をさらにせん断変形させて保持力が加わらないようにして取り外す必要があ る。 他の従来例も治具を必要とし、作業性も悪い。Further, since the force for returning to the original state due to the shear deformation of the rubber bearing member 01 acts on the preliminary shear holding device, when the holding device is detached from the rubber bearing member 01, the rubber bearing member 01 is further re-attached. It must be removed by shearing so that holding force is not applied. The other conventional examples also require a jig and the workability is poor.

【0011】 本考案は、かかる点に鑑みなされたもので、その目的とする処は、支承材をせ ん断変形させる治具や外す際の治具等を特別に必要とせず小型軽量かつ低コスト の簡単な構造で作業性の良い予備せん断変形保持装置を供する点にある。The present invention has been made in view of the above point, and its object is to reduce the size and weight of a supporting member without the need for a jig for cutting and deforming the supporting member and a jig for removing the supporting member. The point is to provide a preliminary shear deformation holding device that has a simple structure with low cost and good workability.

【課題を解決するための手段および作用】[Means and Actions for Solving the Problems]

上記目的を達成するために、本考案は外側面から内側面までの厚さが上部と下 部とで所定長さの異なる一対の保持具を上下逆にして前後に対向させ、両保持具 に、一方の保持具の外側から長尺のボルトを前後方向に貫通して他方の保持具の 外側へ突出したボルト端部にナットを螺合させ、両保持具間にゴム積層体または 同等の機能を有するゴム構造体からなる支承材を挟みせん断変形し保持するゴム 支承材の予備せん断変形保持装置とした。 In order to achieve the above object, the present invention has a pair of holders having different thicknesses from the outer side surface to the inner side surface, the upper and lower portions having different predetermined lengths, which are turned upside down and face each other in the front-back direction. , A long bolt is penetrated from the outside of one holder in the front-rear direction, and a nut is screwed onto the end of the bolt that protrudes to the outside of the other holder, and a rubber laminate or an equivalent function is provided between both holders. A pre-shear deformation holding device for a rubber bearing that sandwiches and holds a bearing made of a rubber structure having

【0013】 前後保持具をボルトが貫通しナットで螺合する簡単な構造であり、小型軽量か つ低コストであり、該せん断変形保持装置自体が支承材をせん断変形させること ができ特別な治具を必要としない。The front and rear holders have a simple structure in which a bolt penetrates and is screwed with a nut, which is small, lightweight, and low cost, and the shear deformation holding device itself can shear deform the support member and has a special jig. You don't need any ingredients.

【実 施 例】【Example】

以下図1ないし図7に図示した本考案の一実施例について説明する。 An embodiment of the present invention shown in FIGS. 1 to 7 will be described below.

【0015】 図1は、支承材1を該予備せん断変形保持装置10が保持した状態を示す斜視図 である。 支承材1は、ゴム積層体2の上下面に金属製の上板3および下板4が固着され たものである。FIG. 1 is a perspective view showing a state in which the supporting member 1 is held by the preliminary shearing deformation holding device 10. The support member 1 is composed of a rubber laminate 2 having upper and lower surfaces to which a metal upper plate 3 and a lower plate 4 are fixed.

【0016】 ゴム積層体2はゴム体内に複数の金属板がゴム層と交互に層をなすように埋設 されたものであり、全体で偏平な立方体状をなしており、その上下面に固着され る上板3および下板4は矩形をなしてゴム積層体2よりも四方にはみ出している 。The rubber laminate 2 is formed by embedding a plurality of metal plates in a rubber body so as to alternately form rubber layers, and has a flat cubic shape as a whole, and is fixed to the upper and lower surfaces thereof. The upper plate 3 and the lower plate 4 are rectangular and extend in all directions from the rubber laminate 2.

【0017】 予備せん断変形保持装置10は、前後の保持具11,12を長尺のボルト13が貫通し ナット14で螺合し締めつけるものである。 前後の保持具11,12は、同形状のものを対称的に上下逆に向い合わせて使用し ている。The pre-shear deformation holding device 10 is one in which a long bolt 13 penetrates the front and rear holders 11 and 12 and is screwed with a nut 14 to tighten them. The front and rear holders 11 and 12 have the same shape and are symmetrically used upside down.

【0018】 前方の保持具11について形状を説明すると、その外側面および左右側面が垂直 面をなし、上下側面が水平面をなし、内側面は上下の垂直面11a,11bが前後に ずれて、外側面から上側垂直面11aまでの厚さの方が下側垂直面11bまでの厚さ より所定長さだけ厚く、上下垂直面11aと11b間は斜面11cで構成されている。The shape of the front holder 11 will be described. The outer side surface and the left and right side surfaces form vertical surfaces, the upper and lower side surfaces form horizontal surfaces, and the inner side surface has upper and lower vertical surfaces 11a and 11b displaced forward and backward. The thickness from the side surface to the upper vertical surface 11a is thicker than the thickness from the lower vertical surface 11b by a predetermined length, and a slope 11c is formed between the upper and lower vertical surfaces 11a and 11b.

【0019】 一方の保持具12も同形であり、上下逆にして保持具11と対向して用いるため、 外側面から上側垂直面12aまでの厚さの方が下側垂直面12bまでの厚さより所定 長だけ薄くなる。Since one of the holders 12 has the same shape and is used upside down so as to face the holder 11, the thickness from the outer side surface to the upper vertical surface 12a is smaller than that from the lower vertical surface 12b. It becomes thinner by a predetermined length.

【0020】 かかる保持具11,12を相対向させ同軸にボルト孔を形成してボルト13を貫通す るようにしている。 この予備せん断変形保持装置10を1個の支承材1に対して左右に配設する。The holders 11 and 12 are opposed to each other, and bolt holes are formed coaxially to penetrate the bolts 13. The preliminary shearing deformation holding device 10 is arranged on the left and right sides of one supporting member 1.

【0021】 図2および図3は、ゴム積層体2をせん断変形する方法および保持状態を示す 側面図であり、図2に示すようにゴム積層体2をせん断変形するには、支承材1 の左右側部において一対の保持具11,12を前後に対向させて、保持具11の上側垂 直面11aを支承材1の上板3の前側面に当てがい、保持具12の下側垂直面12bを 支承材1の下板4の後側面に当てがい、ボルト13を前方から保持具11のボルト孔 に貫通させ、ゴム積層体2側方を通して保持具12のボルト孔に貫通させ、後方へ 突出したねじ部にナット14を螺合する(図2に示す状態)。2 and 3 are side views showing a method of shearing and deforming the rubber laminated body 2 and a holding state thereof. As shown in FIG. The pair of holders 11 and 12 are opposed to each other in the left-right side, and the upper surface 11a of the holder 11 is applied to the front side surface of the upper plate 3 of the support member 1, and the lower vertical surface 12b of the holder 12 is arranged. To the rear surface of the lower plate 4 of the support member 1 so that the bolt 13 penetrates the bolt hole of the holder 11 from the front side and the rubber laminate 2 sideways to penetrate the bolt hole of the holder 12 and protrudes rearward. The nut 14 is screwed into the threaded portion (state shown in FIG. 2).

【0022】 左右ともにこのように予備せん断変形保持装置10を装着したのち、ナット14を さらに螺入していくと、前側の保持具11は支承材1の上板3を後方へ押し、後側 の保持具12は支承材1の下板4を前方へ押し、上板3と下板4を互いに逆方向に 変位してゴム積層体2にせん断変形を生じさせる。After mounting the preliminary shearing deformation holding device 10 on both the left and right as described above, when the nut 14 is further screwed in, the holding tool 11 on the front side pushes the upper plate 3 of the support member 1 rearward, and the rear side. The holder 12 pushes the lower plate 4 of the support member 1 to the front, and displaces the upper plate 3 and the lower plate 4 in opposite directions to cause shearing deformation in the rubber laminate 2.

【0023】 ボルト13とナット14のねじ機構により小さい力でも大きな力が支承材1に作用 し容易にせん断変形することができる。Even if a smaller force is applied to the screw mechanism of the bolt 13 and the nut 14, a large force acts on the support member 1 so that it can be easily sheared and deformed.

【0024】 こうして上板3および下板4が保持具11,12によって挟まれるまでナット14を 螺入していきゴム積層体2のせん断変形を終了し、かつせん断変形を保持する( 図1および図3参照)。In this way, the nut 14 is screwed in until the upper plate 3 and the lower plate 4 are sandwiched by the holders 11 and 12, and the shear deformation of the rubber laminate 2 is completed, and the shear deformation is maintained (FIG. 1 and FIG. 1). (See FIG. 3).

【0025】 このように予備せん断変形保持装置10がゴム積層体2をせん断変形させるので 、特別せん断変形のための専用の治具を必要としない。Since the preliminary shearing deformation holding device 10 causes the rubber laminate 2 to undergo shearing deformation in this way, no special jig for special shearing deformation is required.

【0026】 こうして予備せん断変形保持装置10によりせん断変形保持された支承材1を橋 脚5の上面に、せん断変形方向を橋軸方向として固着する。 この固着には橋脚5に植設されたアンカー部材等により行なわれる。 そして橋桁6を構成する型枠を上板3の上部に配置してコンクリートを打設し 、このコンクリートの養生期間の経過で上板3を橋桁6に固着する。The supporting member 1 thus shear-deformed and held by the preliminary shear-deformation holding device 10 is fixed to the upper surface of the bridge pier 5 with the shear deformation direction being the bridge axis direction. This fixing is performed by an anchor member or the like that is planted in the pier 5. Then, the formwork constituting the bridge girder 6 is arranged on the upper plate 3 and concrete is poured, and the upper plate 3 is fixed to the bridge girder 6 after the curing period of the concrete.

【0027】 このように支承材1の上板3、下板4が各々橋桁6、橋脚5に固着されたのち 、ナット14を緩め前後の保持具11,12による挟持を解除すれば予備せん断変形保 持装置10は簡単に取り外すことができ、このときも予備せん断変形保持装置10を 取り外すための特別な治具を必要としない。After the upper plate 3 and the lower plate 4 of the support member 1 are thus fixed to the bridge girder 6 and the bridge pier 5, respectively, the nut 14 is loosened, and the holding fixtures 11 and 12 before and after releasing the pre-shear deformation. The holding device 10 can be easily removed, and at this time also, a special jig for removing the preliminary shearing deformation holding device 10 is not required.

【0028】 予備せん断変形保持装置10を取外した状態を図5に示す。 支承材1はゴム積層体2が橋軸方向に予めせん断変形された状態で橋脚5と橋 桁6との間に介装されるので、橋桁6の伸縮に対して橋脚5の強度を増したりゴ ム積層体を大きくすることなく対処できる。 以上のように本実施例の予備せん断変形保持装置10は、一対の保持具11,12と ボルト13,14からなる極めて簡単な構造で、小型軽量でコストも安く作業性にも 優れている。FIG. 5 shows a state in which the preliminary shearing deformation holding device 10 is removed. Since the support member 1 is interposed between the bridge pier 5 and the bridge girder 6 in a state where the rubber laminate 2 is sheared and deformed in the bridge axis direction in advance, the strength of the pier 5 can be increased against expansion and contraction of the bridge girder 6. It can be dealt with without increasing the size of the rubber stack. As described above, the preliminary shearing deformation holding device 10 of the present embodiment has an extremely simple structure including the pair of holding tools 11 and 12 and the bolts 13 and 14, and is small in size, light in weight, low in cost and excellent in workability.

【考案の効果】[Effect of device]

本考案は、一対の保持具をボルト・ナットで締め付けることで支承材のゴム積 層体をせん断変形し、かつ変形保持することができるので、せん断変形のための 特別の治具を必要としない。 保持具を取り外すときも同様に特別の治具を必要しない。 一対の保持具とボルト・ナットの簡単な構成なので、小型軽量でありかつ低コ ストで作業性も良い。 According to the present invention, since the rubber laminated body of the support material can be sheared and deformed and held by tightening the pair of holders with the bolts and nuts, no special jig for shearing deformation is required. . Similarly, no special jig is required when removing the retainer. The simple structure of a pair of holders and bolts and nuts makes it compact, lightweight, low cost, and easy to work with.
