Moreover, the suitable example of an installation target object is mainly the wall (part exposed with respect to space. Mainly an inner wall and an outer wall) of various structures (for example, a road, a railway, a bridge, a water pipe, a building). ) And pillars. However, as long as it makes sense to install the protective cover structure and the protection target object, the installation target object is not limited to the wall or pillar of the building. For example, the installation object may be movable, such as a portable base for installing a camera device or a light emitting device.

  The “protection object” in the present application refers to an object disposed inside a cover member constituting the protective cover structure. Suitable examples of the object to be protected mainly include a fire alarm, a sensor device (a device that includes a temperature sensor, a strain sensor, a level, etc., and detects any state or state change of an inspection target), a camera device ( A device equipped with a camera such as a monitoring camera), a light emitting device (a device equipped with a light source for illumination and light emitting display), and a display device (a device for displaying characters and figures such as a bulletin board and a guidance display board). However, the object to be protected is not limited to the sensor device or the like as long as it can be arranged inside the cover member. The object to be protected may be one that is used together with the above device, such as a power supply device or an information transmission / reception device. Further, the object to be protected may be a combination of the above device and other devices.

  As shown in FIG. 1, the protective cover structure 1 according to the first embodiment is a structure that protects a protection target object 200 installed on the installation target object 100. Further, the protection target object 200 is directly installed on the installation target object 100. As the installation method, known methods such as adhesion, fitting, and welding can be used. In addition, when it is not necessary for the protection target 200 to be in direct contact with the installation target 100, the protection target 200 is installed on the installation target 100 with a self-adhesive silicone rubber adhesive member 20 described later interposed therebetween. May be. Moreover, the protection target object 200 may be fixed to a cover member described later.

  The protective cover structure 1 includes a cover member 10, a self-adhesive silicone rubber adhesive member 20, and an installation object side fixing member 30. The installation target object 100 and the protection target object 200 are not components of the protective cover structure 1 in this embodiment. However, the installation object 100 may be included in the components of the protective cover structure 1.

  The cover member 10 is formed by connecting the cover 12 and the cover member side fixing member 14, and can accommodate the protection target object 200 inside the cover 12.
