Description
【０００１】[0001]
この考案は、コンクリート二次製品を緊結するする場合において、主にＰＣ鋼 線の高さを調整可能とし、かぶり部分をコンクリート製もしくはモルタル製の棒 状スペーサーと一体に設けた構築用スペーサーに関する。 The present invention relates to a construction spacer in which the height of a PC steel wire is mainly adjustable when binding a concrete secondary product, and a cover portion is integrally provided with a rod-shaped spacer made of concrete or mortar.
【０００２】[0002]
従来のこの種の構築用スペーサーにおいては、配筋に水平筋を溶接してＰＣ鋼 線を乗せ高さの保持をしているが、鉄筋に溶接すると構造物の強度の低下を引き 起こす。また、鋼線スペーサーを使用すると錆の発生によりコンクリートの剥離 の発生につながる。鉄筋を切断し溶接して取り付けているが作業に多大の労力を 要するものである。 In this type of conventional construction spacer, a horizontal bar is welded to a reinforcing bar and a PC steel wire is placed on the bar to maintain the height. However, welding to a reinforcing bar causes a decrease in the strength of the structure. Also, if steel wire spacers are used, rust will be generated and concrete will be peeled off. The rebar is cut and welded, but requires a lot of work.
【０００３】[0003]
この考案は、上記問題点に鑑みなされたもので、その目的はＰＣ鋼線の位置と 高さが簡単に保持できると共に、かぶり部分をコンクリート製もしくはモルタル 製の棒状スペーサーと一体に設けた事で、コンクリート断面における構造上の欠 損を極力最小限にした、構築用スペーサーを提供するものである。 This invention has been made in view of the above problems, and its purpose is to easily maintain the position and height of the PC steel wire and to provide a cover portion integrally with a concrete or mortar rod-shaped spacer. Another object of the present invention is to provide a construction spacer that minimizes structural damage in a concrete section.
【０００４】[0004]
上記目的を解決するため、この考案はＰＣ鋼線に装着すべく上部をＵ字型に形 成し、高さの調整を可能としたボルトとナットを接続した固定具の適所に、コン クリート製もしくはモルタル製の棒状スペーサーと一体に設ける。 In order to solve the above-mentioned object, this invention has a U-shaped upper part to be attached to a PC steel wire, and a bolt made of concrete that can be adjusted in height. Alternatively, it is provided integrally with a rod-shaped spacer made of mortar.
【０００５】[0005]
この考案の構築用スペーサーは、まずボルトとナットを接続した固定具で高さ の調整を行い、ＰＣ鋼線を上部のＵ字部分に結束し装着することで位置が正確に 確保できるものである。 The height of the construction spacer of this invention can be secured by first adjusting the height with a fixture that connects the bolt and nut, and then binding and mounting the PC steel wire to the upper U-shaped part. .
【０００６】[0006]
以下、この考案の実施例を図１に基づいて詳細に説明する。 １は構築用スペーサーである。 ２は固定具で、ボルト２ａに固定すべく平板を略Ｕ字形に折曲した２ｂをナット ２ｃで固定もしくは溶接で一体的に形成してある。 ３は支持具で、ナット３ａに棒鋼を折曲した３ｂを一体化した先端に棒状のコン クリート製もしくはモルタル製の３ｃを設けた支持棒である。 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 1 is a construction spacer. Reference numeral 2 denotes a fixture, which is formed by fixing or welding a flat plate 2b having a substantially U-shape to be fixed to the bolt 2a by a nut 2c. Reference numeral 3 denotes a support, which is a support rod having a rod-shaped concrete or mortar-made 3c provided at the distal end where a nut 3a formed by bending a steel bar 3b is integrated.
【０００７】 この実施例の使用例として、図２に示すように予め配置されたＰＣ鋼線４に構 築用スペーサー１を一定の間隔に設置し、固定具２ｂとＰＣ鋼線４を結束し固定 する。この状態で垂直方向に突出した支持具３で高さの調整をすることでＰＣ鋼 線４の高さが正確に確保できるものである。As an example of use of this embodiment, as shown in FIG. 2, a spacer 1 for construction is installed at a predetermined interval on a pre-arranged PC steel wire 4, and the fixture 2b and the PC steel wire 4 are bound. Fix it. In this state, the height of the PC steel wire 4 can be accurately secured by adjusting the height with the support 3 protruding in the vertical direction.
【０００８】 なお、上記の固定具ならびに支持棒の長さは、ＰＣ鋼線の高さによって変更す るものである。また、支持棒３ｃはかぶり厚によって変更するもので、型枠に接 する部分は半円状または半球状とし仕上がり面に極力接しない形状とした。[0008] The lengths of the fixing tool and the support rod are changed according to the height of the PC steel wire. Further, the support rod 3c is changed according to the cover thickness, and the portion in contact with the form is semicircular or hemispherical and has a shape which does not contact the finished surface as much as possible.
【０００９】[0009]
この考案は、上記の構成によりＰＣ鋼線の高さの微調整が簡単にできるととも に、型枠に接する部分をコンクリート製もしくはモルタル製を使用した事で、鉄 部の錆発生によるコンクリートの剥離防止ができ、構造部の強度低下を防ぐもの である。また、従来は鉄筋を切断し溶接して取り付けていたが作業工程が多く工 程の短縮を可能とした。 The idea is that the above configuration makes it easy to fine-tune the height of the PC steel wire and uses concrete or mortar for the part in contact with the formwork. It can prevent peeling and prevent the strength of the structure from lowering. In the past, rebars were cut and welded, but the number of work steps was large and the process could be shortened.
