壁、床等の板状のコンクリート部分を打設する際には、
コンクリートを補強するための補強筋を、壁の両表面に
沿って所定の間隔で対向した形で入れる必要がある。(b) Technical background When pouring plate-shaped concrete parts such as walls and floors,
Reinforcement bars to strengthen the concrete must be placed along both sides of the wall at regular intervals.
（Ｃ）従来技術と問題点
従来、この種の補強筋は、溶接金網と呼ばれる、鉄筋を
金網状に溶接接合した部材を用いていたが、この場合、
補強筋を構成する材料が全て鉄であるために、補強筋の

においでは、塑性変形によって所定の補強筋間隔が維持
できなくなり、強度ト不都合が生じることもあった。(C) Conventional technology and problems Conventionally, this type of reinforcing bar used a member called a welded wire mesh, in which reinforcing bars were welded together in the shape of a wire mesh, but in this case,
Since the reinforcing bars are made entirely of iron, the reinforcing bars are heavy and require a great deal of labor to assemble and transport. Moreover, the wire mesh constituting the reinforcing bars is easily plastically deformed due to impact, etc., and in this type of heel reinforcing bars, which are often installed facing each other at a predetermined interval, the predetermined reinforcing bars are easily deformed due to plastic deformation. In some cases, the spacing could no longer be maintained, leading to problems with strength.
（ｄ） 発明の目的
本発明は、曲述の欠点を解消すべく、軽量で、組み立て
運搬等が容易に行なえ、かつ施工上の信頼性の高い板状
補強筋を提供することを目的とするものである。(d) Purpose of the Invention The purpose of the present invention is to provide a plate-shaped reinforcing bar that is lightweight, easy to assemble and transport, and has high reliability in construction, in order to eliminate the drawbacks described above. It is something.
（ｅ） 発明の構成
即ち、本発明は、環状の枠体を設け、前記枠体に高性能
連続繊維からなるロープを網状に張設して構成される。(e) Structure of the Invention That is, the present invention is constructed by providing an annular frame body and stretching a rope made of high-performance continuous fibers in a net shape around the frame body.
（ｆ） 発明の実施例 以下、図面に基き、本発明の詳細な説明する、。(f) Examples of the invention Hereinafter, the present invention will be described in detail based on the drawings.

３の両端は、枠体２に対して、引っ張りに対してほどけ
ることのない、もやい結びで結合されでいる。As shown in Fig. 1, the plate reinforcement l has a square closed annular frame body 2 made of iron, and the frame body 2 is made of carbon fiber or aramid fiber (U.S. Federal Trade Commission (FTC)). ). - For example, DuPont's "Kevlar" (
A rope 3 made of high-performance continuous fibers such as 1,), which is known as a registered trademark), is stretched in a lattice pattern. Both ends of the rope 3 are connected to the frame 2 with a bowline knot that will not unravel under tension.

る。。Table 1 shows the mechanical properties of carbon fiber and aramid fiber as high-performance continuous fibers in comparison with steel. As shown in Table 1, high-performance continuous fibers have a Young's modulus (modulus) comparable to that of steel.
Although its tensile strength is several times that of steel, its density is 1/4 to 115 and extremely lightweight. can. .

とが可能となる。(g) As described in detail, according to the present invention, the annular frame 2 includes:
The ropes 3 made of high-performance continuous fibers that are lightweight and strong are strung in a net shape such as a lattice, making the plate-shaped reinforcing bars l significantly lighter than conventional welded wire meshes made entirely of reinforcing bars. It can be easily assembled and transported. In addition, since the lobes 3 themselves are highly flexible, even if an impact or the like is applied to the lobes 3, they will not undergo plastic deformation like a wire mesh. Therefore, the spacing between reinforcing bars can be maintained at an appropriate value during construction. This makes it possible to increase construction reliability.
なお、第１図の実施例は、ロープ３を格子状に張設した
場合について述べたが、ロープ３は網状に張設する限り

可能である。In the embodiment shown in FIG. 1, the rope 3 is stretched in a grid pattern, but the rope 3 may be in any form as long as it is stretched in a mesh pattern1, for example, as shown in FIG. , it is also possible to stretch it diagonally. Further, the shape of the frame body 2 is not limited to a rectangular ring shape, but may be any ring shape as required. Furthermore, in the embodiment described above, a plurality of ropes 3 are tied to the frame 2 to form a net, but a single continuous rope 3 is hooked to the frame 2. Of course, it is also possible to provide a net-like structure.
