「産業上の利用分野」
本考案は、プレストレストコンクリート用アン
ボンド・フラツトケーブルに係るものである。[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an unbonded flat cable for prestressed concrete.
「従来の技術と考案が解決しようとする課題」
コンクリート建築物において、大梁やスラブに
アンボンドケーブルを用いてプレストレスを導入
することが知られている。``Problems to be solved by conventional technology and ideas'' In concrete buildings, it is known to introduce prestress into girders and slabs using unbonded cables.
アンボンドケーブルは、１本のPC鋼より線に
防錆剤を塗布し、その周りを合成樹脂製チユーブ

導入に当たり、強度上、複数本を列べて用いるこ
とも多く、その場合には、多大な手数がかかつて
いる。 Unbonded cables are made by coating a single PC steel strand with a rust preventive agent and surrounding it with a covering material such as a synthetic resin tube, but when introducing prestressing, multiple strands are connected in a row for strength reasons. In many cases, multiple methods are used, which requires a great deal of effort.

り、また、各アンボンドケーブルの作用が不均一
となり、ロスが多くなる。 It has been considered to use multiple unbonded cables bundled in advance, but this increases the overall diameter, resulting in large misalignment when crossing in two directions, making it difficult to lift a flat girder or slab. It becomes difficult to secure a so-called eccentric distance by bending the middle part downward in order to obtain the effect, and the action of each unbonded cable becomes uneven, resulting in a large amount of loss.
本考案は、斯る問題点を解決しようとするもの
である。 The present invention attempts to solve such problems.
「課題を解決するための手段」

フラツトシース１で包被したことを特徴とする。"Means for Solving the Problem" The present invention consists of arranging a plurality of PC steel stranded wires 2 in a line adjacent to each other, applying a rust preventive to these PC steel strands 2, and It is characterized in that all of these are covered with one flat sheath 1.
上記フラツトシース１は、合成樹脂等から成る
扁平なチユーブ状の被覆材である。 The flat sheath 1 is a flat tube-shaped covering material made of synthetic resin or the like.

せ、いわゆる偏心距離を確保する。``Operation'' Because of the above configuration, when prestressing a girder or slab, the two flat surfaces are placed facing up and down, and overlap each other at the intersection. In addition, the intermediate portion is bent downward to obtain a lifting effect, thereby ensuring a so-called eccentric distance.
「実施例」 図面は、本考案の実施例を示している。"Example" The drawings show an embodiment of the invention.

材たるフラツトシース１により包被したものであ
る。 In the illustrated example, four PC steel stranded wires 2... are arranged in a line adjacent to each other, and a rust preventive agent 2 such as grease is applied to these PC steel stranded wires 2.
The entire structure is covered with a flat sheath 1 which is a flat tube-shaped covering material made of synthetic resin.
なお、PC鋼より線２……の本数は、４本に限
るものではなく、所要により適宜である。 The number of PC steel stranded wires 2 is not limited to four, and may be determined as required.
「考案の効果」
本考案によれば、複数のPC鋼より線２……を
１つのフラツトシース１内に一列に並設している
ので、複数のアンボンドケーブルを必要とすると

る。``Effect of the invention'' According to the invention, multiple PC steel stranded wires 2 are arranged in a row in one flat sheath 1, so when multiple unbonded cables are required, they can be unbonded at once. Wiring is possible, greatly reducing the amount of work involved.
また、PC鋼より線２……が複数であつてもこ

でき、躯体コストを低減できる。 In addition, even if there are multiple PC steel stranded wires 2..., they are arranged in a line, so they can be treated as if they were one wire in terms of diameter, and even if they are crossed in two directions, they will not cross each other on a flat surface. As long as they are overlapped, there will be little misalignment, and even when introducing prestress into low-profile flat girders or slabs, by arranging the two flat surfaces facing up and down, it is possible to create a sufficient downward curve in the middle part. is possible, and a sufficient eccentric distance can be secured.
It is possible to accurately obtain the required lifting effect, in other words, it is possible to reduce the thickness of girders and slabs, the height of the building can be lowered, and space can be used effectively, and construction is easy. This can shorten the construction period and reduce the construction cost.

レストレス導入ができ、巻き取り、取り扱いを容
易にできる。 Furthermore, since the PC steel strands 2 are arranged in a line, these effects can be made uniform, prestress can be efficiently introduced, and winding and handling can be facilitated.
