Description

本発明は、切梁中継具に関するものである。   The present invention relates to a beam cutting tool.

既設構造物の補強のために、コンクリート構造物の周囲に補強用の鉄筋コンクリートを新たに打設する補強方法が採用されている。
その場合に、橋脚のような一部が地中に埋設されている既設の構造物を補強するためには、図９に示すように、構造物の周囲に矢板などの山留め壁を打設して開削して構造物の表面を露出させなければならない。
開削に際して山留め壁を支持し安定させるには、山留め壁と既設構造物の表面との間に腹起、切梁を配置する必要がある。
しかし構造物の表面には補強コンクリートを取り付ける必要があるから、切梁の端面を既設構造物に直接、接触させて位置させては補強コンクリートの取り付けの障害となる。
さらに補強コンクリートの内部には多数本の鉄筋を配置させることから、その点からも切梁の端面を既設構造物に直接、接触させて位置させることはできない。
類似の工法として特許文献１のような発明が知られている。
特許第３６６８１７７号公報。 In order to reinforce an existing structure, a reinforcing method in which reinforcing reinforced concrete is newly placed around the concrete structure is employed.
In that case, in order to reinforce an existing structure that is partially buried in the ground, such as a pier, as shown in FIG. 9, a mountain retaining wall such as a sheet pile is placed around the structure. Must be excavated to expose the surface of the structure.
In order to support and stabilize the retaining wall at the time of excavation, it is necessary to arrange an abdomen and a cutting beam between the retaining wall and the surface of the existing structure.
However, since it is necessary to attach reinforced concrete to the surface of the structure, if the end face of the beam is placed in direct contact with the existing structure, it becomes an obstacle to the installation of the reinforced concrete.
Furthermore, since a large number of reinforcing bars are arranged inside the reinforced concrete, the end face of the cut beam cannot be positioned in direct contact with the existing structure from that point.
As a similar construction method, an invention as in Patent Document 1 is known.
Japanese Patent No. 3668177.

前記した特許文献１記載の切梁の連結具は、新たなコンクリート構造物の構築の際に使用するものであって、既設構造物の補強に使用するものではない。
また、新たなコンクリート構造物の内部に、構造と関係のない連結具を残置することになり、補強コンクリートの一部に異物が残ってしまう。
The cut beam coupler described in Patent Document 1 is used when a new concrete structure is constructed, and is not used for reinforcing an existing structure.
Moreover, the connection tool unrelated to a structure will be left in the inside of a new concrete structure, and a foreign material will remain in a part of reinforced concrete.

上記のような課題を解決する本発明の切梁中継具は、既設構造物と、その周囲の山留め壁面に配置した腹起との間に切梁を配置する場合の部材であって、既設構造物の表面に取り付ける構造物当板と、切梁の端面に取り付ける切梁当板と、平行した両板の間に、直交方向に介在させる複数本の支持脚とにより構成し、既設構造物の表面に取り付けるための構造物当板に、支持脚の一端を解体自在に取り付け、その支持脚の他端に、切梁当板を解体自在に取り付けて構成した、切梁中継具を特徴としたものである。
The beam relay tool of the present invention that solves the above-described problems is a member for arranging a beam between an existing structure and an abdomen arranged on a surrounding retaining wall, and the existing structure It is composed of a structure plate attached to the surface of the object, a beam support plate attached to the end face of the beam, and a plurality of support legs that are interposed between the parallel plates in the orthogonal direction, on the surface of the existing structure. It features a beam relay that is constructed by attaching one end of the support leg to the structural plate to be attached so that it can be disassembled and attaching the beam support plate to the other end of the support leg. is there.

本発明の切梁中継具は以上説明したようになるから次のような効果を得ることができる。
＜１＞ 既設構造物と山留め壁との間に切梁を配置して、山留め壁の一方から作用する土圧を既設構造物に伝達して支持することができる。
＜２＞ 補強コンクリートの内部に残すのは構造物当板だけであり、他の部材はすべて回収することができる。したがってきわめて経済的な中継具である。
＜３＞ 補強コンクリートの内部に、構造に関係しない異物をほとんど、残すことがなく、補強コンクリートのすべてを有効に機能させることができる。
Since the beam relay tool of the present invention is as described above, the following effects can be obtained.
<1> A beam can be arranged between the existing structure and the retaining wall, and earth pressure acting from one of the retaining walls can be transmitted to and supported by the existing structure.
<2> Only the structural plate is left inside the reinforced concrete, and all other members can be recovered. Therefore, it is a very economical relay tool.
<3> Almost all of the reinforced concrete can be functioned effectively without leaving any foreign matter not related to the structure inside the reinforced concrete.

以下図面を参照にしながら本発明の好適な実施の形態を詳細に説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

＜１＞全体の構成。
本発明の切梁中継具Ａは、既設構造物Ｂと、その周囲に配置した山留め壁の腹起Ｃとの間に切梁Ｄを配置する場合の中継用の部材である。
そしてこの切梁中継具Ａは、構造物当板１と切梁当板２と、両板の間に配置する支持脚３とによって構成する。 <1> Overall configuration.
The beam relay tool A according to the present invention is a member for relay when the beam D is disposed between the existing structure B and the uplift C of the retaining wall disposed around the existing structure B.
The beam relay tool A is composed of a structure hitting plate 1, a beam hitting plate 2, and a support leg 3 disposed between the plates.

＜２＞構造物当板１。
構造物当板１は、既設構造物Ｂの表面に取り付ける鋼製の板体である。
この構造物当板１だけは、補強コンクリートＧを打設した後にはその内部に埋設され回収の対象にならないが薄い鋼板であり補強コンクリートへの影響はほとんどない。
構造物当板１の既設構造物Ｂへの取り付け方法は、一般的にはボルトによって行う。
しかしボルトに限定する必要はなく、アンカー打設、接着剤による接着など公知の各種のコンクリートへ取り付け方法を採用することができる。 <2> Structural plate 1.
The structure contact plate 1 is a steel plate attached to the surface of the existing structure B.
Only this structural abutment plate 1 is buried in the reinforced concrete G after being placed and is not an object of recovery, but is a thin steel plate and has little influence on the reinforced concrete.
The method of attaching the structure abutment plate 1 to the existing structure B is generally performed by bolts.
However, it is not necessary to limit to bolts, and it is possible to adopt various well-known concrete attachment methods such as anchor placement and adhesive bonding.

＜３＞切梁当板２。
切梁当板２は、切梁Ｄの端面に取り付ける鋼製の板体である。
したがって切梁当板２の寸法は、ほぼ切梁Ｄの端面の寸法と同一に構成する。
切梁当板２と切梁Ｄとの取り付けは、自由に解体を行えるように、たとえばボルトによって行う。
そのために切梁当板２にはボルト穴を形成しておく。
このボルト穴は図の実施例では一箇所であるが、複数個所に開設しておくこともできる。 <3> Cut beam contact plate 2.
The cut beam abutment plate 2 is a steel plate attached to the end face of the cut beam D.
Therefore, the dimensions of the cut beam abutment plate 2 are substantially the same as the dimensions of the end face of the cut beam D.
The cut beam abutment plate 2 and the cut beam D are attached by, for example, bolts so that they can be freely disassembled.
For this purpose, a bolt hole is formed in the cut beam abutment plate 2.
Although this bolt hole is one place in the illustrated embodiment, it can be opened at a plurality of places.

＜４＞支持脚３。
支持脚３は鋼製の棒状体である。
この複数本の支持脚３を、平行に配置した構造物当板１と切梁当板２との間に配置する。
すなわち、この支持脚３の一端は構造物当板１に解体自在に取り付ける。
支持脚３の他端は、切梁当板２に解体自在に取り付ける。
支持脚３の直径は、全長にわたって等しい寸法でもよいが、特に構造物当板１に接する側を細く、切梁当板２に接する側を太く構成することもできる。
このように構成すると、後述するような補強コンクリートＧの硬化後に支持脚３を補強コンクリートＧの内部から引き抜く際に容易となる。
支持脚３の長さと、構造物当板１の厚さの合計が、補強コンクリートＧの厚さとほぼ同一である。
なお、構造物当版１と支持脚３との結合部を逆ねじにしておくことも可能である。 <4> Support leg 3.
The support leg 3 is a steel rod-shaped body.
The plurality of support legs 3 are arranged between the structure hitting plate 1 and the beam hitting plate 2 arranged in parallel.
That is, one end of the support leg 3 is attached to the structure abutment plate 1 so as to be disassembled.
The other end of the support leg 3 is attached to the beam cutting plate 2 so as to be disassembled.
The diameter of the support leg 3 may be equal throughout the length, but in particular, the side in contact with the structure abutment plate 1 can be made thin, and the side in contact with the cut beam abutment plate 2 can be made thick.
If comprised in this way, it will become easy when pulling out the support leg 3 from the inside of the reinforced concrete G after hardening of the reinforced concrete G which is mentioned later.
The sum of the length of the support legs 3 and the thickness of the structural plate 1 is substantially the same as the thickness of the reinforced concrete G.
In addition, it is also possible to make the coupling | bond part of the structure this version 1 and the support leg 3 into a reverse screw.

＜５＞支持脚３の取り付け構造。
支持脚３の一端と構造物当板１とを、相互に取り付けと解体が自由であるように構成する。
そのために、たとえば構造物当板１の側にナット穴を設け、支持脚３の一端にはボルトを突設しておく。
あるいはその反対の構造、すなわち構造物当板１の側にボルトを突設し、支持脚３の一端にはナット穴を設けておく構造を採用することもできる。
支持脚３の他端も、切梁当板２と相互に取り付けと解体が自由であるように構成する。
そのためにたとえば切梁当板２に貫通穴を設け、支持脚３の他端にはナット穴を設けておく。
そして切梁当板２の外部から支持脚固定ボルト３１を挿入して支持脚３の他端のナット穴にねじ込めば、切梁当板２と支持脚３とは取り付け、解体を自由に構成できる。
切梁当板２のボルト穴の周囲に、底のある浅い凹部を形成しておけば、支持脚固定ボルト３１の頭部が切梁当板２の表面から露出しない。
なお支持脚３の切梁当板２の側にボルトを突設しておき、切梁当板２の貫通穴を貫通したボルトに、外部からナットをねじ込めば、切梁当板２と支持脚３とは取り付け、解体を自由に構成できる。 <5> Mounting structure of the support leg 3.
One end of the support leg 3 and the structure abutment plate 1 are configured to be freely attached to and disassembled from each other.
For this purpose, for example, a nut hole is provided on the structure contact plate 1 side, and a bolt is projected from one end of the support leg 3.
Alternatively, the opposite structure, that is, a structure in which a bolt projects from the structure contact plate 1 side and a nut hole is provided at one end of the support leg 3 can also be adopted.
The other end of the support leg 3 is also configured to be freely attached to and dismantled from the beam cutting plate 2.
For this purpose, for example, a through hole is provided in the beam support plate 2 and a nut hole is provided in the other end of the support leg 3.
If the support leg fixing bolt 31 is inserted from the outside of the beam support plate 2 and screwed into the nut hole at the other end of the support leg 3, the beam support plate 2 and the support leg 3 can be attached and disassembled freely. it can.
If a shallow concave portion having a bottom is formed around the bolt hole of the cut beam abutment plate 2, the head of the support leg fixing bolt 31 is not exposed from the surface of the cut beam abutment plate 2.
If a bolt is projected from the support leg 3 on the side of the beam support plate 2 and a nut is screwed into the bolt that has penetrated the through hole of the beam support plate 2, the beam support plate 2 and the support leg 3 are supported. The leg 3 can be attached and disassembled freely.

＜６＞使用方法。
次に本発明の中継具の使用方法について説明する。
まず、構造物当板１と支持脚３、及び切梁当板２を取り付けてから配筋を行う例を説明するが、鉄筋Ｅの配筋を行ってから支持脚３、及び切梁当板２を取り付ける工法を採用することも可能である。 <6> Usage method.
Next, the usage method of the relay tool of this invention is demonstrated.
First, an example in which reinforcing bar placement is performed after attaching structure hitting plate 1, support leg 3, and beam cutting plate 2 will be described. It is also possible to employ a method of attaching 2.

＜７＞構造物当板１の取り付け。
まず橋脚などの既設構造物Ｂの表面に構造物当板１を取り付ける。
この構造物当板１は回収するものではないから、どのような取り付け方法によってもよい。
たとえば構造物当板１に貫通穴を開口しておき、既設構造物Ｂの表面に形成したナット穴に貫通穴を通してボルトをねじ込んで、構造物当板１を取り付けることができる。
その後に既設構造物Ｂの周囲に多数本の鉄筋Ｅを配置する。 <7> Attaching the structural plate 1.
First, the structure abutment plate 1 is attached to the surface of an existing structure B such as a pier.
Since this structural plate 1 is not collected, any attachment method may be used.
For example, the structure contact plate 1 can be attached by opening a through hole in the structure contact plate 1 and screwing a bolt through a through hole into a nut hole formed on the surface of the existing structure B.
Thereafter, a large number of reinforcing bars E are arranged around the existing structure B.

＜８＞支持脚３の取り付け。
配筋後に、構造物当板１に直交する方向で、支持脚３を取り付ける。
その際にすでに既設構造物Ｂの外側には多数本の鉄筋Ｅが交差している。
しかし鉄筋Ｅ群の間には隙間があるから、図８に示すように、棒状体である支持脚３を鉄筋Ｅの隙間を貫通させて取り付けることができる。
構造物当板１への取り付けは、支持脚３の先端をねじとして構成しておけば、鉄筋Ｅ群の外部から支持脚３を回転するだけで取り付けることができ、鉄筋Ｅの存在も支持脚３の取り付けの障害にならない。
支持脚３の直径が同一でない場合には、細い側を構造物当板１に取り付け、太い側を切梁当板２に取り付ける。
さらに支持脚３の周囲に厚紙などを巻きつけると、コンクリートの硬化後における支持脚３のコンクリート内部からの引き抜きが容易となる。
支持脚３の長さと構造物当板１の厚さの合計は、前記したように補強コンクリートＧの厚さとほぼ同一である。 <8> Attaching the support leg 3.
After the bar arrangement, the support legs 3 are attached in a direction perpendicular to the structure abutment plate 1.
At that time, a number of reinforcing bars E already cross the outside of the existing structure B.
However, since there is a gap between the reinforcing bars E, the support leg 3 that is a rod-like body can be attached through the gap of the reinforcing bar E as shown in FIG.
If the tip of the support leg 3 is configured as a screw, it can be attached to the structure abutment plate 1 simply by rotating the support leg 3 from the outside of the reinforcing bar E group. 3 is not an obstacle to the installation.
When the diameters of the support legs 3 are not the same, the thin side is attached to the structure abutment plate 1, and the thick side is attached to the cut beam abutment plate 2.
Further, when cardboard or the like is wound around the support legs 3, the support legs 3 can be easily pulled out from the concrete after the concrete is hardened.
The sum of the length of the support legs 3 and the thickness of the structural plate 1 is substantially the same as the thickness of the reinforced concrete G as described above.

＜９＞切梁当板２の取り付け。
支持脚３の他端には切梁当板２を取り付ける。
支持脚３への取り付けは、前記したようなボルト、ナットの組み合わせによって取り付けと解体が自由であることが必要である。 <9> Attaching the cutting plate 2
At the other end of the support leg 3, a beam-clamping plate 2 is attached.
The attachment to the support leg 3 needs to be free of attachment and disassembly by the combination of bolts and nuts as described above.

＜１０＞切梁Ｄなどの取り付け。
切梁当板２の表側に、切梁Ｄの一端をねじ止めして取り付ける。
さらに切梁当板２の周囲には型枠Ｆを鉛直に立てて、図示しない支保工などの公知の手段で型枠Ｆの位置を固定する。
型枠Ｆの既設構造物Ｂ側の面と、切梁当板２の面とはほぼ同一面を形成し、この面が補強コンクリートＧの外面となる。 <10> Mounting of the beam D and the like.
One end of the beam D is screwed to the front side of the beam stopper plate 2 and attached.
Further, the formwork F is set up vertically around the cutting plate 2 and the position of the formwork F is fixed by a known means such as a supporting work (not shown).
The surface on the existing structure B side of the formwork F and the surface of the cut beam abutment plate 2 form substantially the same surface, and this surface becomes the outer surface of the reinforced concrete G.

＜１１＞後から配筋する場合。
既設構造物Ｂの表面に構造物当板１を取り付けたら、すぐに支持脚３を取り付け、その支持脚３群に切梁当板２を取り付ける場合もある。
この切梁当板２に切梁Ｄを取り付けて切梁としての機能を確保する。
こうして複数段の切梁Ｄを設置し、最深部までの掘削が完了したら、その後に鉄筋Ｅを配筋する。
その場合には、構造物Ｂの表面からは多数本の支持脚３が突出しているから、その位置を避けて、支持脚３の隙間を貫通させて鉄筋Ｅを配筋することになる。
しかし鉄筋Ｅの配置位置は事前に分かっていて墨出しを行えるから、その位置を避けて構造物当板１を設置すれば支持脚３に鉄筋Ｅが当たることはない。 <11> When arranging bars later.
When the structure hitting plate 1 is attached to the surface of the existing structure B, the support leg 3 may be immediately attached, and the beam support plate 2 may be attached to the support leg 3 group.
A cutting beam D is attached to the cutting plate 2 to ensure the function as a cutting beam.
In this way, a plurality of cut beams D are installed, and after excavation to the deepest part is completed, reinforcing bars E are arranged thereafter.
In that case, since a large number of support legs 3 protrude from the surface of the structure B, the rebars E are arranged through the gaps of the support legs 3 while avoiding the positions.
However, since the arrangement position of the reinforcing bar E is known in advance and the ink marking can be performed, the reinforcing bar E will not hit the support leg 3 if the structure abutment plate 1 is installed avoiding that position.

＜１２＞補強コンクリートの打設。
既設構造物Ｂの表面と、型枠Ｆおよび切梁当板２で形成された面との間に補強コンクリートＧを打設する。
この補強コンクリートＧの厚さは、構造物当板１の厚さと支持脚３の長さの合計にほぼ等しいものとなる。 <12> Placing reinforced concrete.
Reinforced concrete G is placed between the surface of the existing structure B and the surface formed by the formwork F and the cutting beam contact plate 2.
The thickness of the reinforced concrete G is approximately equal to the sum of the thickness of the structural plate 1 and the length of the support legs 3.

＜１３＞中継具の解体、回収。
補強コンクリートＧが硬化したら型枠Ｆを解体し、補強コンクリートＧの表面を養生した後、開削部の埋め戻しを行う。
埋め戻しに平行して切梁Ｄを取り外してゆく。
切梁Ｄを取り外したら、補強コンクリートＧの表面には切梁当板２の表面が露出した状態となる。
さらに切梁当板２の表面には支持脚３固定ボルトの頭部が露出しているから、このボルトを回転すれば、切梁当板２を支持脚３から取り外して回収することができる。
さらに支持脚３を外部から回転して構造物当板１との取り付けを解体して補強コンクリートＧから引き抜く。
この際に、支持脚３の直径が同一ではなく、外部の方を大きくしてあれば、その引き抜きがさらに容易となる。
こうして、すべての切梁Ｄの設置位置の切梁当板２と支持脚３群を簡単に回収することができる。
回収後の空洞は無収縮モルタルなどを充填しておく。
<13> Dismantling and collection of relay tools.
When the reinforced concrete G is hardened, the formwork F is dismantled, the surface of the reinforced concrete G is cured, and then the cut-out portion is backfilled.
The beam D is removed in parallel with the backfilling.
When the cut beam D is removed, the surface of the cut beam abutment plate 2 is exposed on the surface of the reinforced concrete G.
Further, since the head of the support leg 3 fixing bolt is exposed on the surface of the beam support plate 2, the beam support plate 2 can be removed from the support leg 3 and recovered by rotating this bolt.
Further, the support leg 3 is rotated from the outside to disassemble the attachment to the structure abutment plate 1 and pulled out from the reinforced concrete G.
At this time, if the diameters of the support legs 3 are not the same and the outside is made larger, the pulling out becomes easier.
In this way, it is possible to easily collect the beam contact plate 2 and the support leg 3 group at the installation positions of all the beam D.
The recovered cavity is filled with non-shrink mortar.
