上記スライド式支承体の固定構造においては、上部構造物の伸縮等により生じた支承体との隙間の寸法を測定し、その測定結果に応じてスペーサやカラー等の介装部材を作製して、作製した介装部材を隙間に取り付けて固定支承とする手順となる。よって、寸法測定後に介装部材を設計・作製する日数が余計に必要となって施工期間が長くなってしまう。特に介装部材も支承体の金属部材と同様に防錆処理が必要となるため、さらに時間が掛かることになる。また、介装部材の作製中に生じた新たな寸法変化により、作製した介装部材と現場の隙間との寸法が合わなくなるおそれもある。   In the fixed structure of the above-mentioned slide type bearing body, measure the dimension of the gap with the bearing body caused by expansion and contraction of the upper structure, etc. It becomes the procedure which attaches the produced interposed member to a clearance gap, and makes it a fixed support. Therefore, the number of days for designing / manufacturing the intervention member after the dimension measurement is required, and the construction period becomes long. In particular, the intervention member also needs to be rust-proofed in the same manner as the metal member of the support body. Moreover, there is a possibility that the dimension between the produced interposed member and the gap in the field may not match due to a new dimensional change that occurs during the production of the interposed member.

そこで、本発明は、隙間の寸法測定後直ちに介装部材を隙間に合わせてセットでき、施工期間の短縮化に繋がるスライド式支承体の固定構造及び固定方法、スライド式支承体の固定用の介装部材を提供することを目的としたものである。   Therefore, the present invention can set the interposition member to the gap immediately after measuring the dimension of the gap, and the fixing structure and fixing method of the slide type bearing body, which leads to the shortening of the construction period, and the intervention for fixing the sliding type bearing body. The object is to provide a mounting member.

The intermediate plate 7 is a metal plate having a quadrangular shape in plan view, in which both the horizontal longitudinal direction and the horizontal lateral direction are smaller than the upper flange 5, and a pair of sides in the horizontal longitudinal direction parallel to the side blocks 11, 11. Notches 22 and 22 into which the rising portions 13 and 13 are loosely fitted are formed on the sides.
The bottom friction plate 8 has a disk shape that fits into a circular recess 23 formed at the center of the upper surface of the intermediate plate 7, and protrudes upward from the upper surface of the intermediate plate 7 in the fitted state.
The stainless steel plate 9 is attached to the lower surface of the upper collar 5, and the lower surface is in contact with the upper surface of the low friction plate 8 and can slide with respect to each other.

そして、図5に示すように、下沓4の各サイドブロック11の立ち上がり部13と、上沓5の凹部18との間に形成される4カ所の隙間Sには、支承体3を固定支承として機能させるための介装部材30がそれぞれ設けられている。
この介装部材30は、図6,7に示すように、帯板状の固定部31と、固定部31と直角に繋がり、固定部31より幅広な四角板状のスペーサ部32とからなる平面視L字状の金属製で、後述する調整スペーサ35A〜35Cも含めて下沓4及び上沓5と同様に予め表面全体に防錆処理が施されている。
固定部31には、固定部31の長手方向に延びる長孔33,33が、長手方向に沿って2つ貫通形成されている。
Then, as shown in FIG. 5, the support body 3 is fixed to the four gaps S formed between the rising portions 13 of the side blocks 11 of the lower rod 4 and the recesses 18 of the upper rod 5. An intervening member 30 is provided for functioning.
As shown in FIGS. 6 and 7, the intervention member 30 is a plane composed of a band plate-like fixing portion 31 and a square plate-like spacer portion 32 that is connected to the fixing portion 31 at a right angle and is wider than the fixing portion 31. It is made of an L-shaped metal, and the entire surface is subjected to rust prevention treatment in advance in the same manner as the lower rod 4 and the upper rod 5 including adjustment spacers 35A to 35C described later.
Two long holes 33, 33 extending in the longitudinal direction of the fixed portion 31 are formed through the fixed portion 31 in the longitudinal direction.

一方、スペーサ部32は、図8にも示すように、固定部31へ直角に連設され、固定部31よりも厚みが大きい基本スペーサ34と、基本スペーサ34に、連結部材としての2本の皿ネジ36,36によって着脱可能に取り付けられる3枚の調整スペーサ35A〜35Cとからなる。
調整スペーサ35A〜35Cは、基本スペーサ34から最も離れた調整スペーサ35Aが最も厚みが大きく、そこから調整スペーサ35B、35Cの順に厚みが小さくなっている。具体的な数値を例示すると、基本スペーサ34は、最低限必要な厚みとして10mmに設定されて、調整スペーサ35A〜35Cは、想定される隙間Sの変動幅(3〜10mm)に対応して、調整スペーサ35Aが4mm、調整スペーサ35Bが2mm、調整スペーサ35Cが1mmに設定されている。
ここでは基本スペーサ34にネジ孔37が、調整スペーサ35B,35Cに透孔38,38が形成され、最外の調整スペーサ35Aにはザグリ孔39が貫通形成されている。また、調整スペーサ35A〜35Cを含むスペーサ部32の先端部下側には、切欠40が形成されている。
On the other hand, as shown in FIG. 8, the spacer portion 32 is connected to the fixing portion 31 at a right angle, and has a basic spacer 34 having a thickness larger than that of the fixing portion 31, and the basic spacer 34 and two connecting members as connecting members. It consists of three adjustment spacers 35A to 35C that are detachably attached by countersunk screws 36, 36.
As for the adjustment spacers 35A to 35C, the adjustment spacer 35A farthest from the basic spacer 34 has the largest thickness, and the adjustment spacers 35B and 35C decrease in thickness from there. To illustrate specific numerical values, the basic spacer 34 is set to 10 mm as the minimum necessary thickness, and the adjustment spacers 35A to 35C correspond to the assumed fluctuation width (3 to 10 mm) of the gap S, The adjustment spacer 35A is set to 4 mm, the adjustment spacer 35B is set to 2 mm, and the adjustment spacer 35C is set to 1 mm.
Here, screw holes 37 are formed in the basic spacer 34, through holes 38, 38 are formed in the adjustment spacers 35B, 35C, and counterbore holes 39 are formed through the outermost adjustment spacer 35A. Further, a notch 40 is formed on the lower side of the distal end portion of the spacer portion 32 including the adjustment spacers 35A to 35C.

よって、スペーサ部32は、調整スペーサ35A〜35Cの全てが皿ネジ36,36により基本スペーサ34に取り付けられてスペーサ部32の厚みが最大となる第1パターンと、調整スペーサ35A,35Bのみが取り付けられて第1パターンの次に厚みが小さい第2パターンと、調整スペーサ35A,35Cのみが取り付けられて第2パターンの次に厚みが小さい第3パターンと、調整スペーサ35Aのみが取り付けられて第3パターンの次に厚みが小さい第4パターンと、調整スペーサ35A〜35Cの何れも取り付けられず基本スペーサ34のみとなって第4パターンの次に厚みが小さい第5パターンとの5段階に厚みが調整可能となっている。   Therefore, only the spacers 32A to 35C are attached to the first pattern in which all of the adjustment spacers 35A to 35C are attached to the basic spacer 34 by the countersunk screws 36 and 36 and the thickness of the spacer part 32 is maximum, and the adjustment spacers 35A and 35B are attached. The second pattern having the next smallest thickness after the first pattern, the third pattern having the second smallest thickness after the second pattern, and the third pattern having the second smallest thickness, and the third spacer having only the adjustment spacer 35A attached. The thickness is adjusted in five stages: the fourth pattern with the next smallest thickness after the pattern and the basic spacer 34 without any of the adjustment spacers 35A to 35C, and the fifth pattern with the next smallest thickness after the fourth pattern. It is possible.

図5に示す例では、各介装部材30のスペーサ部32を、基本スペーサ34のみで最も厚みが小さい第5パターンとして、固定部31を、上沓5の水平長手方向の側面にあてがい、スペーサ部32を各隙間Sに嵌合させて、切欠40を凹部18の段部19に係止させて位置決めした状態で、固定部31をボルト41,41によって上沓5に固定している。これにより、上沓5が下沓4側に対して水平長手方向での移動が規制された固定支承となっている。   In the example shown in FIG. 5, the spacer portion 32 of each intervention member 30 is set as the fifth pattern having the smallest thickness only with the basic spacer 34, and the fixing portion 31 is applied to the side surface of the upper collar 5 in the horizontal longitudinal direction. The fixing portion 31 is fixed to the upper collar 5 by bolts 41 and 41 in a state where the portion 32 is fitted in each gap S and the notch 40 is locked to the stepped portion 19 of the recess 18 and positioned. Thereby, the upper collar 5 is a fixed support in which movement in the horizontal longitudinal direction is restricted with respect to the lower collar 4 side.

以上の如く構成された支承体3の施工は、以下のように行われる。
上沓5を中間板7の低摩擦板8と上沓5のステンレス板9との間でスライド可能とした状態で、下部構造物1であるコンクリート橋脚に設けた凹部内に下沓4のアンカーボルト10を配置し、凹部内にコンクリートを打設して下沓4と下部構造物1とを固定する。
この間に上部構造物2が水平長手方向へ伸縮すると、低摩擦板8上でステンレス板9がスライドして上沓5が下沓4に対して水平長手方向へ変位する。このとき、上沓5の凹部18と下沓4の立ち上がり部13との間には、予め隙間Sが設定されているので、上沓5が変位しても立ち上がり部13と干渉することはない。
Construction of the support body 3 configured as described above is performed as follows.
The anchor of the lower rod 4 is placed in the recess provided in the concrete pier which is the lower structure 1 with the upper rod 5 being slidable between the low friction plate 8 of the intermediate plate 7 and the stainless steel plate 9 of the upper rod 5. Bolts 10 are arranged, and concrete is placed in the recesses to fix the lower rod 4 and the lower structure 1.
During this time, when the upper structure 2 expands and contracts in the horizontal longitudinal direction, the stainless steel plate 9 slides on the low friction plate 8 and the upper rod 5 is displaced in the horizontal longitudinal direction with respect to the lower rod 4. At this time, since a gap S is set in advance between the concave portion 18 of the upper collar 5 and the rising portion 13 of the lower collar 4, it does not interfere with the rising portion 13 even if the upper collar 5 is displaced. .

下沓4と下部構造物1との固化後、各立ち上がり部13の前後に形成される隙間S,Sが、介装部材30のスペーサ部32の厚みよりも小さい場合は、各介装部材30を、スペーサ部32を基本スペーサ34のみの第5パターンとして、図5に示すように、スペーサ部32を隙間Sに嵌合させて固定部31を上沓5にボルト41,41で固定すれば、上沓5が下沓4側に対して水平長手方向での移動が規制された固定支承となる。
一方、隙間Sが基本スペーサ34の厚みよりも大きい場合は、例えば各介装部材30を、スペーサ部32に全ての調整スペーサ35A〜35Cを取り付けた第1パターンとして、図9に示すように、スペーサ部32を隙間Sに嵌合させて固定部31を上沓5にボルト41,41で固定すれば、同様に上沓5を固定できる。
なお、何れの場合も水平長手方向での固定部31の位置は、ボルト41を貫通させる長孔33によって微調整できる。また、スペーサ部32の嵌合時には、左右の第1係合面13aと第2係合面18aとの間にそれぞれスポンジ又はゴム板を介在させて、スペーサ部32を密着させるのが望ましい。
When the gaps S and S formed before and after each rising portion 13 are smaller than the thickness of the spacer portion 32 of the interposed member 30 after the lower rod 4 and the lower structure 1 are solidified, each interposed member 30 If the spacer portion 32 is a fifth pattern including only the basic spacer 34 and the spacer portion 32 is fitted in the gap S and the fixing portion 31 is fixed to the upper collar 5 with bolts 41 and 41 as shown in FIG. The upper collar 5 is a fixed support in which movement in the horizontal longitudinal direction is restricted with respect to the lower collar 4 side.
On the other hand, when the gap S is larger than the thickness of the basic spacer 34, for example, each interposed member 30 is formed as a first pattern in which all the adjustment spacers 35A to 35C are attached to the spacer portion 32, as shown in FIG. If the spacer portion 32 is fitted in the gap S and the fixing portion 31 is fixed to the upper rod 5 with bolts 41, 41, the upper rod 5 can be similarly fixed.
In any case, the position of the fixing portion 31 in the horizontal longitudinal direction can be finely adjusted by the long hole 33 through which the bolt 41 passes. Further, when the spacer portion 32 is fitted, it is desirable to closely contact the spacer portion 32 by interposing a sponge or a rubber plate between the left and right first engaging surfaces 13a and the second engaging surfaces 18a.

また、上沓5の変位によって立ち上がり部13の前後に形成される隙間S,Sの大きさが不均一であっても、基本スペーサ34に取り付ける調整スペーサ35A〜35Cの数を変更して各隙間Sごとに合わせたパターンを選択すれば、隙間Sに嵌合させることができる。
こうして固定された支承体3では、上部構造物2に水平長手方向の変位や回転力が作用すると、ゴム体6が追従して変位し、振動や横揺れを緩和することができる。
Further, even if the sizes of the gaps S, S formed before and after the rising portion 13 due to the displacement of the upper collar 5 are not uniform, the number of the adjustment spacers 35A to 35C attached to the basic spacer 34 is changed to change the gaps. If a pattern matched to each S is selected, the gap S can be fitted.
In the support body 3 fixed in this way, when the displacement or rotational force in the horizontal longitudinal direction acts on the upper structure 2, the rubber body 6 follows and displaces, and vibration and roll can be reduced.

このように、上記形態の介装部材30を用いた支承体3の固定構造及び固定方法によれば、下沓4側には、上部構造物2の水平長手方向で前後に位置する一対の第1係合面13a,13aが、上沓5側には、水平長手方向で一対の第1係合面13a,13aとそれぞれ対峙する一対の第2係合面18a,18aがそれぞれ形成されると共に、第1係合面13aと第2係合面18aとの間には、水平長手方向で4つの隙間Sが形成されて、各隙間Sには、水平長手方向で複数に分割されるスペーサ部32を備えた介装部材30のスペーサ部32が、隙間Sの大きさに合わせて選択した数でそれぞれ嵌合されることで、下沓4と上沓5との水平長手方向での相対移動が規制されている。
よって、隙間Sの寸法測定後直ちに介装部材30を隙間Sに合わせてセットできる。よって、介装部材30を隙間Sに合わせて設計・作製する必要がなくなり、施工期間の短縮化に繋がる。また、介装部材30と現場の隙間Sとの寸法が合わなくなるおそれが生じず、支承体3を確実に固定できる。
Thus, according to the fixing structure and fixing method of the support body 3 using the interposition member 30 of the said form, a pair of 1st located in the front-back direction in the horizontal longitudinal direction of the upper structure 2 on the lower collar 4 side. A pair of second engagement surfaces 18a, 18a that respectively face the pair of first engagement surfaces 13a, 13a in the horizontal longitudinal direction are formed on the upper flange 5 side of the first engagement surfaces 13a, 13a, respectively. Between the first engagement surface 13a and the second engagement surface 18a, four gaps S are formed in the horizontal longitudinal direction, and each gap S is divided into a plurality of spacers in the horizontal longitudinal direction. The spacer part 32 of the interposition member 30 provided with 32 is fitted in a number selected according to the size of the gap S, so that the lower rod 4 and the upper rod 5 are relatively moved in the horizontal longitudinal direction. Is regulated.
Therefore, the intervention member 30 can be set according to the gap S immediately after measuring the dimension of the gap S. Therefore, it is not necessary to design / manufacture the interposition member 30 in accordance with the gap S, which leads to a shortened construction period. Moreover, there is no possibility that the dimensions of the interposition member 30 and the gap S at the site do not match, and the support body 3 can be reliably fixed.

特にここでは、介装部材30は、下沓4側に固定される固定部31を有し、スペーサ部32は、固定部31に連設される基本スペーサ34と、基本スペーサ34に別体で積層される3つの調整スペーサ35A〜35Cとを備えることで、厚みの調整と固定とが容易に行える。
また、3つの調整スペーサ35A〜35Cは互いに厚みが異なるので、厚みのバリエーションが多くなって選択の幅が広がる。
さらに、介装部材30は、固定部31とスペーサ部32との間が直角となる平面視L字状であるため、位置決めや取付がしやすくなる。
Particularly, here, the interposition member 30 has a fixing portion 31 fixed to the lower collar 4 side, and the spacer portion 32 is separated from the basic spacer 34 provided continuously to the fixing portion 31 and the basic spacer 34. By providing the three adjustment spacers 35A to 35C to be stacked, the thickness can be easily adjusted and fixed.
In addition, since the three adjustment spacers 35A to 35C have different thicknesses from each other, variations in thickness increase and the range of selection increases.
Furthermore, since the interposition member 30 is L-shaped in plan view in which the space between the fixed portion 31 and the spacer portion 32 is a right angle, positioning and attachment are easy.

加えて、調整スペーサ35A〜35Cを、皿ネジ36を介して基本スペーサ34へ着脱可能に連結しているので、選択した調整スペーサ35A〜35Cの固定が容易に行え、脱落も生じにくくなる。
そして、介装部材30には防錆処理が施されているので、防錆処理による施工期間の延長が回避できる。
In addition, since the adjustment spacers 35A to 35C are detachably connected to the basic spacer 34 via the countersunk screws 36, the selected adjustment spacers 35A to 35C can be easily fixed and are not easily dropped.
And since the rust prevention process is given to the intervention member 30, the extension of the construction period by a rust prevention process can be avoided.

なお、上記形態では、介装部材を平面視L字状としているが、図10,11に示す介装部材30Aのように、2つの貫通孔45,45を備えた固定部31と、固定部31よりも幅広の基本スペーサ34とが直線状に繋がる一枚板形状としてもよい。ここでは調整スペーサ35A〜35Cを、固定部31と基本スペーサ34とを含む形状で形成して固定部31側の端部に、貫通孔45,45と同心の2つの透孔46,46をそれぞれ形成している。よって、貫通孔45,45と共に透孔46,46へボルト41,41を貫通させることで、調整スペーサ35A〜35Cを固定部31側で固定して反対側でスペーサ部32が形成可能となっている。   In addition, in the said form, although the intervention member is made into L shape in planar view, like the intervention member 30A shown to FIG. 10, 11, the fixing | fixed part 31 provided with two through-holes 45 and 45, and a fixing | fixed part The basic spacer 34 wider than 31 may be formed in a single plate shape connected in a straight line. Here, the adjustment spacers 35 </ b> A to 35 </ b> C are formed in a shape including the fixed portion 31 and the basic spacer 34, and two through holes 46 and 46 concentric with the through holes 45 and 45 are formed at the end on the fixed portion 31 side, respectively. Forming. Therefore, the adjustment spacers 35A to 35C can be fixed on the fixing portion 31 side and the spacer portion 32 can be formed on the opposite side by passing the bolts 41 and 41 through the through holes 46 and 46 together with the through holes 45 and 45. Yes.

この介装部材30Aを用いる場合、図12〜14に示すように、スペーサ部32を第1係合面13aと第2係合面18aとの隙間Sに嵌合させて、固定部31を、上沓5ではなく立ち上がり部13の第1係合面13a,13aに、貫通孔45,45及び透孔46,46を介して調整スペーサ35A〜35Cごとボルト41,41で固定する。ここでも隙間Sに対してスペーサ部32の幅が合わなければ、調整スペーサ35A〜35Cの数を変更して隙間Sに合わせたパターンを選択すればよい。また、図15に示すように、調整スペーサ35A〜35Cを全て外して基本スペーサ34のみを隙間に嵌合させるパターンとしてもよい。
このように、介装部材30Aを、固定部31とスペーサ部32とが直線状となる平板状とすれば、介装部材30Aを第2係合面18aに沿わせてスライドさせながらスペーサ部32を隙間Sへ嵌合させることができ、嵌合させやすくなる。
When using this intervention member 30A, as shown in FIGS. 12 to 14, the spacer portion 32 is fitted into the gap S between the first engagement surface 13a and the second engagement surface 18a, and the fixing portion 31 is The adjustment spacers 35 </ b> A to 35 </ b> C are fixed to the first engagement surfaces 13 a and 13 a of the rising portion 13 instead of the upper collar 5 with the bolts 41 and 41 through the through holes 45 and 45 and the through holes 46 and 46. Here, if the width of the spacer portion 32 does not match the gap S, the number of the adjustment spacers 35A to 35C may be changed and a pattern matched to the gap S may be selected. Moreover, as shown in FIG. 15, it is good also as a pattern which removes all the adjustment spacers 35A-35C and fits only the basic spacer 34 in a clearance gap.
Thus, if the interposition member 30A is formed in a flat plate shape in which the fixing portion 31 and the spacer portion 32 are linear, the spacer portion 32 is slid while sliding the interposition member 30A along the second engagement surface 18a. Can be fitted into the gap S, which makes it easier to fit.

一方、基本スペーサと調整スペーサとの連結は、ネジ等の連結部材による他、例えば図16に示す介装部材30Bのように、基本スペーサ34に係合凹部47を、各調整スペーサ35A〜35Cに、係合凹部47に嵌合する係合凸部48と、係合凹部47と同じ形状及び深さの係合凹部49をそれぞれ表裏両面に一又は複数個設けて(但し、最外の調整スペーサ35Aには係合凸部48のみを設けている)、凹凸同士の嵌合によって互いに着脱可能に連結することも可能である。
このように、調整スペーサ35A〜35Cを、隣接する他の調整スペーサ35A〜35Cに対して互いに着脱可能に係合させるようにすれば、皿ネジ等の連結部材を用いなくても調整スペーサ35A〜35Cの着脱が容易に行える。なお、係合による着脱は調整スペーサ同士に限らず、基本スペーサや固定部に対して互いに係合させるようにしてもよい。
また、上記形態及び変更例において、調整スペーサの数や厚みは上記形態に限らず、適宜変更可能で、厚みの異なる調整スペーサの数を増やせばより細かい隙間への対応が可能となる。さらに、固定部及びスペーサ部の形状も適宜変更可能である。
On the other hand, the basic spacer and the adjustment spacer are connected by a connecting member such as a screw or the like, for example, an interposition member 30B shown in FIG. One or a plurality of engagement protrusions 48 that fit into the engagement recesses 47 and one or more engagement recesses 49 having the same shape and depth as the engagement recesses 47 are provided on each of the front and back surfaces (however, the outermost adjustment spacer 35A is provided with only the engaging projection 48), and it is also possible to connect the projections and recesses so as to be detachable.
As described above, when the adjustment spacers 35A to 35C are detachably engaged with the other adjacent adjustment spacers 35A to 35C, the adjustment spacers 35A to 35C can be used without using a connecting member such as a flat head screw. 35C can be easily attached and detached. The attachment / detachment by the engagement is not limited to the adjustment spacers, and may be engaged with each other with respect to the basic spacer or the fixed portion.
Moreover, in the said form and the example of a change, the number and thickness of an adjustment spacer are not restricted to the said form, It can change suitably, and if it increases the number of adjustment spacers from which thickness differs, it can respond to a finer gap. Furthermore, the shapes of the fixed portion and the spacer portion can be changed as appropriate.

そして、下沓や上沓、ゴム体や中間板、立ち上がり部等の形状も上記形態に限らず適宜変更可能で、上記形態では下沓側の立ち上がり部を上沓の凹部に遊嵌させているが、これと逆に、下沓側に凹部を、上沓側に凸部を設けて遊嵌させ、生じた隙間に介装部材を介在させてもよい。隙間の数も上記形態に限定されない。
また、上記形態では、支承体の下沓側を先に下部構造物側へ固定して上沓側を上部構造物の伸縮に伴ってスライドさせて、生じた隙間を介装部材で固定するようにしているが、これと逆に、支承体の上沓側を先に上部構造物側へ固定して下沓側を上部構造物の伸縮に伴ってスライドさせ、生じた隙間を介装部材で固定する構造であっても本発明は適用可能である。
さらに、上部構造物及び下部構造物については、コンクリート桁、鋼桁、コンクリート橋脚、鋼橋脚の任意の組み合わせに適用することができる。
The shape of the lower collar, upper collar, rubber body, intermediate plate, rising part, etc. is not limited to the above form, and can be changed as appropriate. In the above form, the rising part on the lower collar side is loosely fitted into the recess of the upper collar. However, conversely, a concave portion may be provided on the lower collar side and a convex portion may be provided on the upper collar side for loose fitting, and an interposition member may be interposed in the generated gap. The number of gaps is not limited to the above form.
Further, in the above embodiment, the lower collar side of the support body is first fixed to the lower structure side, and the upper collar side is slid along with the expansion and contraction of the upper structure, and the generated gap is fixed by the interposed member. On the contrary, the upper collar side of the support body is fixed to the upper structure side first, and the lower collar side is slid as the upper structure expands and contracts. The present invention can be applied even if the structure is fixed.
Further, the upper structure and the lower structure can be applied to any combination of concrete girders, steel girders, concrete piers, and steel piers.
