【課題】鉄筋保持具を改良し、簡便でありながら確実に鉄筋位置を固定する保持具を提供する。【解決手段】主として連結用鉄筋を簡便に位置決めする鉄筋保持具の形態を維持しつつ、梁部、又は支持部に容易に変形可能となる断面縮小用スリット部を追加し、あるいは貫通孔板の板厚みを減少させ、鉄筋を貫通孔に挿通後、人為でその部を曲げあるいは旋回し変形させる事で平行に対設された貫通孔板部の取り付け角度が変わり、貫通孔の相対的な断面の変形縮小により鉄筋に接する事で確実な位置決め固定手段となる。【選択図】図3An object of the present invention is to improve a reinforcing bar holder and to provide a holder that can easily and reliably fix the position of a reinforcing bar. While maintaining the form of a reinforcing bar holder for easily positioning a connecting reinforcing bar, a cross-section reducing slit part that can be easily deformed is added to a beam part or a supporting part, or a through hole plate is provided. By reducing the plate thickness and inserting the reinforcing bar through the through hole, the mounting angle of the through hole plate part that is parallelly installed is changed by bending or turning the part manually to change the relative cross section of the through hole. It becomes a reliable positioning and fixing means by coming into contact with the rebar by the deformation reduction. [Selection] Figure 3

Description

本願考案は、鉄筋コンクリート構造物施工での主として構造物連結用鉄筋(タイバー)の保持具装置に関する。   The present invention relates to a retainer device for reinforcing bars (tie bars) mainly for connecting structures in construction of reinforced concrete structures.

鉄筋コンクリート舗装を例として説明すると、施工機械の施工幅や施工条件により分割施工となる場合、先行施工する側面には連結用鉄筋鉄筋(以後タイバー)を設置し、後施工される舗装部と結合させ舗装全体を一体化し安定させています。この接合部はコールドジョイントとも呼ばれる部であり、各構造体を連結一体化させるため標準的にタイバーが使用されています。   In the case of reinforced concrete pavement as an example, when split construction is performed depending on the construction width and construction conditions of the construction machine, connecting rebars (hereinafter referred to as tie bars) are installed on the side to be pre-constructed, and combined with the pavement part to be constructed later The entire pavement is integrated and stabilized. This joint is also called a cold joint, and tie bars are typically used to connect and integrate each structure.

鉄筋コンクリート分割舗装で標準的に使用されるタイバーは、異形棒鋼D22mmを使用しています。基本長を1mとするが分割舗装をするために、これを2分割し片側にソケット(雌ねじ)、他側にネジ加工してあります。先行施工時にソケット付きタイバーを接合側面に突き合せ埋設し、施工後にソケット部に雄ネジ付きタイバーを締め込みタイバー設置完了となります。その後、後行施工をして各構造体が一体化するのです。   The standard tie bar used in reinforced concrete split pavement uses deformed steel bar D22mm. Although the basic length is 1 m, in order to perform split pavement, it is divided into two parts, sockets (female threads) on one side, and screws on the other side. The tie bar with socket is embedded in the joint side at the time of prior construction, and the tie bar installation is completed by tightening the tie bar with male screw in the socket after construction. After that, the subsequent construction is performed and the structures are integrated.

従来のタイバー位置決め・固定の方法は、チェアと呼ばれる異形棒鋼D13mmで加工された長手方向に連続するタイバーの専用台を使用しています。タイバーを乗せて結束線で結束固定すると、高さ位置、通り方向がセットされるように予め加工されています。(特許文献1)   The conventional tie bar positioning / fixing method uses a dedicated tie bar stand in the longitudinal direction that is processed with a deformed steel bar D13mm called a chair. It is pre-processed so that the height position and street direction are set when a tie bar is placed and fixed with a binding wire. (Patent Document 1)

既にタイバー設置の簡便化となるタイバー保持具の実用新案を出願されています。(特許文献2 実用新案登録第3151740号) 本考案者は、前記実用新案の権利を所有する会社の技術員です。タイバー保持具は、シンプルな鉄製加工品であり配列された鉄筋からぶら下げ固定し、タイバー貫通孔にタイバーを挿通し、重力を利用する事で何等の固定材料(結束線等)を必要とせず位置決め固定を可能とするものであり、その特徴として容易に長手方向の位置を随時調整できる事にありました。近年舗装工事に利用されるスリップフォーム工法に最適のタイバー位置決め具とされるものです。   A utility model has already been filed for a tie bar holder that makes tie bar installation easier. (Patent Document 2 Utility Model Registration No. 3151740) The inventor is a technician of a company that owns the rights of the utility model. The tie bar holder is a simple iron work product that is fixed by hanging from the arranged reinforcing bars, inserted into the through hole of the tie bar, and using gravity to position without any fixing material (bundling wire, etc.). The feature is that it can be fixed, and its feature is that the position in the longitudinal direction can be easily adjusted at any time. This tie bar positioning tool is most suitable for the slip form method used in paving work in recent years.

旧来より施工される方法としてセットフォーム型工法を主とするユーザーより更なる要望がありました。それは、既に位置決めされたタイバーにその他組付け材料がぶつかったり、堰板(型枠)の設置時に接触したとき、時にタイバー位置がずれてしまうケースがあったとの事で、タイバー保持具の形状を維持しつつ、更に位置決め後の固定を強化して欲しい旨要望されました。セットフォーム型工法では、舗装端部に堰板を設置しタイバーを堰板に突き当てて固定するので、タイバー位置を随時調整する必要は無く、1回の設置時でしっかり固定できる事が要件となります。   There have been further requests from users who mainly use the set-form method as a traditional construction method. The tie bar holder was shaped when other assembly materials collided with the already positioned tie bar or when the tie bar (formwork) was in contact with the tie bar. There was a request that we would like to strengthen the fixation after positioning while maintaining it. In the set-form type construction method, a dam plate is installed at the end of the pavement, and the tie bar is abutted against the dam plate and fixed. The

次に実施の形態を示す図面に基づき本願考案による鉄筋保持具を更に詳しく説明します。なお、便宜上同一の機能を奏する部分には同一の符号を付してその説明を省略します。   Next, the reinforcing bar holder according to the present invention will be described in more detail based on the drawings showing the embodiments. For convenience, parts having the same functions are denoted by the same reference numerals and description thereof is omitted.

連続鉄筋コンクリート舗装を実施例とし説明します。構造体内部には縦筋D16mm(10a)、横筋D13mm(10b)を格子状に組み合わせた構造用鉄筋(10)がコンクリート厚みの下方より2/3の位置に配置されます。縦筋が格子上部に位置し縦筋間隔は150mmです。保持具(1)の梁部(2)は所定の長さ(標準長200mm)を有し、少なくとも隣り合う2本の縦筋上に載置されます。梁部(2)の両端には支持部(3)、及び貫通孔(5)のある貫通孔板(4)が対設されています。既実用新案では貫通孔(5)の形状を定め重力を利用した方法として簡易位置決めを可能とするための貫通孔の形状を考案しましたが、本願考案では、貫通孔はタイバーよりやや大となる開口部であり形状を問いません。以下、例として単丸円の貫通孔として説明します。   A continuous reinforced concrete pavement will be explained as an example. Inside the structure, structural reinforcing bars (10), which are a combination of vertical bars D16mm (10a) and horizontal bars D13mm (10b), are arranged at a position 2/3 below the concrete thickness. The vertical bars are located at the top of the grid and the vertical bar spacing is 150 mm. The beam part (2) of the holder (1) has a predetermined length (standard length 200 mm) and is placed on at least two adjacent vertical bars. At both ends of the beam part (2), a support part (3) and a through hole plate (4) with a through hole (5) are provided. In the existing model, the shape of the through hole (5) was determined and the shape of the through hole was devised to enable simple positioning as a method using gravity. However, in the present invention, the through hole is slightly larger than the tie bar. It is an opening and does not matter the shape. In the following, a single round through hole is used as an example.

梁部(2)をく形とする固定方法は、上記に沿って予めタイバー保持具梁部中央に変形しやすくするためのスリットとなる断面縮小部(6)を追加しており、タイバーを貫通孔に挿通し位置を定めた後、梁部(2)をく形に変形させ連結用鉄筋(7)を固定させます。く形とする事で貫通孔(5)の円が相対的に楕円形となりタイバーにしっかり接する事で固定されます。現在標準の梁部(2)・支持部(3)は軟鉄製であり幅12.7mm、厚み2.9mmの寸法です。仮に貫通孔(5)径が24.0mm、連結用鉄筋(7)の山部外径が23.8mmの場合、変形角度16.4度でタイバーが固定される事が実験で確認されており、梁部長さを20cmとすると、変形量(直線中央部が、く形に変形し固定に必要な中央部の移動量)は、29.5mm移動する事で達成します。人為的に梁部変形をするには、簡易にはハンマーによる打撃でも、専用の曲げ治具(12)でも可能です。   In the method of fixing the beam part (2) to a rectangular shape, a cross-sectional reduction part (6) serving as a slit for easy deformation is added to the center of the tie bar holder beam part in advance along the above, and the tie bar is penetrated. After setting the insertion position through the hole, deform the beam (2) into a square and fix the connecting rebar (7). By making it square, the circle of the through hole (5) becomes relatively elliptical and is fixed by firmly contacting the tie bar. The standard beam part (2) and support part (3) are currently made of soft iron and have dimensions of 12.7mm in width and 2.9mm in thickness. If the diameter of the through hole (5) is 24.0 mm and the outside diameter of the peak of the connecting rebar (7) is 23.8 mm, it has been confirmed by experiments that the tie bar is fixed at a deformation angle of 16.4 degrees. If the beam length is 20 cm, the deformation (the center of the straight line is deformed into a square shape and the center is necessary for fixing) can be achieved by moving 29.5 mm. In order to artificially deform the beam part, it is possible to simply hit with a hammer or use a special bending jig (12).

又、既実用新案で考案された保持具の梁部にスリットを追加することで、本考案とを合わせ持つ両用の位置決めの方法、つまり重力を利用した随時位置調整が可能となる方法、又は設置時点でしっかり固定してしまう方法が選択可能な保持具となります。   In addition, by adding a slit to the beam part of the holder devised in the existing utility model, a positioning method for both purposes combined with the present invention, that is, a method that enables adjustment at any time using gravity, or installation The method of fixing firmly at the time is a selectable holder.

支持部(3)を水平ねじり形とする固定方法は、上記に沿って予め両支持部中央に変形しやすいスリット(6)を追加した保持具(1)に、タイバーを貫通孔に挿通し位置を定めた後、支持部(3)を水平にねじり変形させタイバーを固定させます。支持部(3)を旋回する事で貫通孔(5)の円が相対的に楕円形となりタイバーに接し固定されます。仮に貫通孔径が24.0mm、連結用鉄筋の山部外径が23.8mmの場合、16.4度で連結用鉄筋が固定される事が実験で確認されており、旋回変形角度は16.4度です。
人為的に支持部旋回変形をするには、簡易にはモンキーレンチでも、専用の曲げ治具でも可能です。
The fixing method in which the support portion (3) is a horizontal torsion is formed by inserting the tie bar into the through hole in the holder (1) to which a slit (6) that is easy to deform is added in the center in advance along the above. After fixing, fix the tie bar by twisting the support part (3) horizontally. By turning the support part (3), the circle of the through hole (5) becomes relatively oval and fixed in contact with the tie bar. If the diameter of the through-hole is 24.0 mm and the outer diameter of the peak portion of the connecting rebar is 23.8 mm, it has been experimentally confirmed that the connecting rebar is fixed at 16.4 degrees. 4 degrees.
In order to artificially deform the support part, it is possible to use a monkey wrench or a dedicated bending jig.

貫通孔(5)のある貫通孔板(4)を水平ねじり形とする固定方法は、上記に沿って予め貫通孔板(4)を変形し易い板厚み(設定では、1.6mm厚み)とした保持具(1)に、タイバーを貫通孔に挿通し位置を定めた後、貫通孔板(4)を水平にねじり変形させタイバーを固定させます。貫通孔板(4)を旋回する事で貫通孔(5)の円が相対的に楕円形となりタイバーに接し固定されます。仮に貫通孔径が24.0mm、連結用鉄筋の山部外径が23.8mmの場合、16.4度で連結用鉄筋が固定される事が実験で確認されており、旋回変形角度は16.4度です。
人為的に貫通孔板(4)を旋回変形をするには、簡易にはモンキーレンチでも、専用の曲げ治具でも構いません。
The fixing method in which the through-hole plate (4) having the through-hole (5) is horizontally twisted has a plate thickness (1.6 mm thickness in the setting) in which the through-hole plate (4) is easily deformed in advance along the above. Insert the tie bar into the through hole in the holder (1), set the position, and then twist the through hole plate (4) horizontally to fix the tie bar. By turning the through-hole plate (4), the circle of the through-hole (5) becomes relatively oval and fixed in contact with the tie bar. If the diameter of the through-hole is 24.0 mm and the outer diameter of the peak portion of the connecting rebar is 23.8 mm, it has been experimentally confirmed that the connecting rebar is fixed at 16.4 degrees. 4 degrees.
In order to artificially swivel and deform the through hole plate (4), either a monkey wrench or a dedicated bending jig can be used.

本考案のスリットとなる断面欠損部(6)については、梁部、支持部に設けられるスリット形状は、以下の要件を充たす事で機能を有する範囲でどのような形状としても良く、その位置についても限定されません。
* スリット部の断面欠損により生コンクリート打設時の衝撃で変形しない事。
* 塑性変形時の材料破断の無い材料(例 軟鉄等)である事。
About the cross-sectional defect | deletion part (6) used as the slit of this invention, the slit shape provided in a beam part and a support part may be any shape in the range which has a function by satisfying the following requirements, About the position Is not limited.
* Don't be deformed by impact when placing concrete in the slit due to a cross-sectional defect.
* Material that does not break during plastic deformation (eg, soft iron).

本考案では、貫通孔(5)の形状の制限は無い事を前記しています。仮に正方形の貫通孔とした場合でも貫通孔板(4)を旋回する事で貫通孔(5)の正方形が相対的に長方形となり幅縮小によりタイバーに接し固定されます。又、貫通孔(5)が一部解放したU字形のような形状でも同様な効果を奏します。   In the present invention, there is no restriction on the shape of the through hole (5). Even if it is a square through-hole, turning the through-hole plate (4) makes the square of the through-hole (5) relatively rectangular and is fixed in contact with the tie bar by reducing the width. The same effect can be achieved with a U-shaped shape with part of the through hole (5) open.

既実用新案の製品は、現在軟鋼材により製造されていますが、保持具材料は上記要件の性能を有する有機材料、その他の材料によるものでも良いのです。    Already utility model products are currently manufactured from mild steel, but the retainer material can be organic or other materials with the above performance requirements.

本願考案による鉄筋保持具は、実施例としたコンクリート舗装の土木関係の他、広く鉄筋コンクリート構造物を用いる建築関係にも利用する事ができます。   Reinforcing bar holders according to the present invention can be used not only for civil engineering of concrete pavement as an example, but also for construction related to reinforced concrete structures.
