どの破壊を阻止乃至困難にすることが求められている。(Background of the Invention) Due to the diversification of criminal tactics, in recent years, incidents have occurred in which windows, doors, wall surfaces, etc. are forcibly destroyed and intruded into buildings to rob money and the like inside. . Regarding such crimes, even if an intruder is detected by the intruder detection sensor installed in the building, the criminal escapes before the guards who arrive after detecting the intruder arrive at the scene Therefore, it is required to quickly detect a destruction act applied to a wall surface or the like and to prevent or make the destruction of the wall surface or the like difficult.

【発明が解決しようとする課題】しかしながら、第１の
方法にあっては、壁面などが短時間で破壊されるのを回
避（困難に）できるものの、破壊行為を検知できないた
め犯行を阻止できないという問題点があった。However, in the first method, it is possible to avoid (make difficult) the destruction of a wall or the like in a short time, but it is impossible to prevent a crime because a destructive action cannot be detected. There was a problem.
【０００５】また第２の方法にあっては、壁面などに加
えられる破壊行為を検知できるものの、強度が付与され
ていないため、犯人により壁面などが短時間で破壊され
侵入され易いという問題点があった（かくして、壁面な
どに補強手段あるいは破壊検知手段の一方の手段のみを
施工した場合には十分な防犯効果が得られない）。In the second method, although a destructive action applied to a wall surface or the like can be detected, the strength is not given, so that the wall surface or the like is easily destroyed and invaded by a criminal in a short time. (Thus, if only one of the reinforcing means and the destruction detecting means is applied to a wall or the like, a sufficient crime prevention effect cannot be obtained).
【０００６】さらに第３の方法にあっては、（イ）通
例、壁面とフィルム状センサ（破壊検知手段）の接着力
よりもフィルム状センサと強化フィルム（補強手段）の
接着力の方が強く、壁面などが破壊されても強化フィル

め、破壊検知能力が弱く破壊行為の検知が遅れる傾向に
ある；（ロ）フィルム状センサと強化フィルムをそれぞ
れ取り付ける必要があり設置作業が煩雑で面倒である；
という問題点があった。Further, in the third method, (a) the adhesive force between the film sensor and the reinforced film (reinforcing means) is generally stronger than the adhesive force between the wall surface and the film sensor (destruction detecting means). Even if the wall surface is broken, the film sensor does not break until the reinforced film breaks, so the destruction detection ability is weak and the detection of vandalism tends to be delayed; (b) The film sensor and the reinforced film are attached respectively. Installation work is complicated and troublesome;
There was a problem.

（ハ）既存の壁面などに設置する場合、パネルの肉厚を
薄くすることには限界があるため、設置スペースの深さ

てしまうことがある；等の問題点があった。In the fourth method, (a) the thickness of the plastic material is large, so that the flexibility is poor and the price is generally high; (b) the panel is large and large when the installation area is large. Since it becomes heavy, it takes time for transportation and installation work (for efficient transportation and installation work, the panel may be divided into small panels of a predetermined size in advance, but in this case, the small panel may be formed. The strength of the joint between the panel and the small panel decreases, and a sufficient reinforcing effect cannot be expected);
(C) When installing on an existing wall, there is a limit to reducing the thickness of the panel. If the installation space is not deep enough, the panel may protrude from the installation surface and emerge. There are problems;

が少ない。Thus, the destruction detection / protection material 1A is easily bent independently and the destruction detection / protection material 1A
Since the protective member 1A is disposed at a substantially central portion in the thickness direction, it is difficult for compressive stress and tensile stress to be applied to the conductive member 21 by simply bending the protective member 1A.
Even if the protective material 1A is deformed, the influence on the conductive member 21 is small.

In contrast, when the conductive powder-containing molded body 23 is used, the electrical resistance value gradually changes from the point of time when stress is applied to the conductive member. When the containing molded body 23 is used, a destructive action can be detected with higher sensitivity than when the conductive fiber bundle is used, and the range of identifiable stress can be widened. Thus, by using the conductive powder-containing molded body 23 as the conductive member, it becomes possible to detect breakage and detect minute deformation occurring in the protective material.

By forming the fracture detection / protection material 1E in a lattice shape, it is possible to perform reinforcement in a direction orthogonal to the reinforcing fiber bundle that could not be reinforced when formed in a tape shape as in the first embodiment. In addition, since the entire bonding area is increased, the break detection / protection material 1E is more difficult to peel off from the detection target when installed on the detection target.

When the detection is performed, it is determined whether or not a destruction has been performed by measuring the electric resistance value of the conductive member and comparing the measured value with a threshold value. FIG. 2 is a block diagram showing a configuration example of an application example in which a vandalism is detected by using a security function and a result is output to a security system or a threatening means. This configuration block diagram will be briefly described below. Electrical resistance detection means 81 is connected to electrodes 30 and 31 attached to both ends of the conductive member 21 of the destruction detection / protection material 1. The electric resistance detecting means 81 detects the electric resistance of the conductive member 21. The comparing means 82 compares the electric resistance value detected by the electric resistance value detecting means 81 with a preset threshold value, and when the electric resistance value becomes higher than the threshold value, detects that vandalism has been performed and detects a detection signal. Is output to the signal output means 83. Signal output means 83

壊検知・防護材を提供できる。The present invention is configured as described above, and has the following effects according to the present invention. Because the breakage detection and protection material is formed by applying thin and flexible tape-shaped using conductive material, reinforcing fiber bundle, resin material, regardless of the height and width of the wall to be installed, It can be installed at any desired location, and even when it is installed on an existing wall surface, the installation portion does not protrude from the wall surface and emerge. Since it is hard to be damaged even if it is bent until it is attached, even if a wall or the like to be subjected to breakage detection / reinforcement is curved, it can be suitably installed on the target object. By using a conductive fiber having a lower elongation than the reinforcing fiber or a conductive powder-containing molded body as the conductive member, it is possible to detect a break-up action such as a wall surface to be detected before the reinforcing fiber breaks. It is possible to abandon or end the intrusion by destruction by prolonging the time from the detection of a break-up action due to a change in the electrical resistance value of the conductive member to the complete breakage of the reinforcing fiber. Becomes possible. By placing the conductive member at the approximate center in the thickness direction, compressive stress and tensile stress are less likely to be applied to the conductive member even if the fracture detection / protection material is bent. It can be wound and stored and transported, and storage and transport handling is easy. By sandwiching the destruction detection / protection material formed in a tape shape with a resin film, the adhesion area with the wall to be destruction detection / reinforcement can be widened and difficult to peel off, and if an opaque resin film is used, destruction will occur. Detecting and protective materials can be installed in a way that is invisible to human eyes. Further, by providing a color or pattern on the surface of the resin film, it is possible to provide a destruction detection / protection material that can endure aesthetically. The detection member has a maximum elongation rate smaller than the maximum elongation rate of the reinforcing fiber bundle, and is formed by combining a plurality of conductive fibers having different maximum elongation rates, so that the deformation of the fracture detection target is stepped. It is possible to provide a destruction detection / protection material that can be detected in a targeted manner.
