  The large beam 28 is a beam extending from the wall surface 14 to the wall surface 16, and is disposed in the vicinity of the end of the wall surfaces 14, 16 on the wall surface 18 side. The girder 28 is placed on the upper surface of the four rubber bearings 34. The end portion on the wall surface 14 side is placed on the upper surface of the two rubber bearings 34a, and the end portion on the wall surface 16 side is placed on the upper surface of the two rubber bearings 34b. The girder 28 is a member that supports the plurality of covering units 30 and the plurality of connecting units 32, and is a member that does not substantially bend even when a load is applied to the plurality of covering units 30 and the plurality of connecting units 32. .

The two steel sliding supports 48 are arranged at the end portions of the two rod-shaped members 40 on the wall surface 12 side. The steel sliding bearing 48 is fixed to the wall surface 12. The steel sliding support 48 supports the rod-shaped member 40 with respect to the wall surface 12 in a state in which it can move in a predetermined direction, that is, in a state in which relative movement is possible.

  As shown in FIGS. 2, 3, and 4, the covering unit 30 includes two rod-shaped members 40, a plurality of connecting portions 42, a reinforcing portion 43, and a net 44 in the extending direction of the large beam 28. A covering structure that covers a part of the region between the large beam 28 and the wall surface 12 is formed. The covering unit 30 is fixed to the large beam 28 by a fixing member 46 and supported by a steel sliding support 48 in a state slidable with respect to the wall surface 12.

  The connecting unit 32 is disposed between the covering unit 30 and the adjacent covering unit 30 in the longitudinal direction of the large beam 28, that is, in the direction in which the covering units 30 are arranged. The connecting unit 32 covers the space between the covering unit 30 and the adjacent covering unit 30. The connecting unit 32 is also disposed between the covering unit 30 and the wall surface 14 and covers the space between the covering unit 30 and the wall surface 14. The connecting unit 32 is also disposed between the covering unit 30 and the wall surface 16 and covers the space between the covering unit 30 and the wall surface 16.

The connecting body 60 is disposed in the longitudinal direction of the covering unit 30 (the extending direction of the rod-shaped member 40). The connection body 60 is disposed in proximity to the adjacent connection body 60. The coupling body 60 includes a plate portion 61, a fixing member 62, and a sliding member 64. The plate part 61 is a plate-like member such as a metal plate or a plastic plate. The plate portion 61 may have the same configuration as the covering portion formed by the two rod-like members 40 of the covering unit 30, the plurality of connecting portions 42, the reinforcing portion 43, and the net 44. The fixing member 62 is disposed between the plate portion 61 and one of the covering units 30. The fixing member 62 fixes the plate portion 61 to the one coating unit 30.

  As described above, the connection unit 60 is fixed to the one covering unit 30 and is slidably supported by the other covering unit 32. Thereby, the connecting unit 32 covers the space between the covering units 30 while suppressing the transmission of force between the one covering unit 30 and the other covering unit 30.

  The flying object protection equipment 20 has the above structure. The flying object protection equipment 20 can cover the upper surface of the protection target device 10 by arranging a plurality of covering units 30 in a row and covering each of them with a connecting unit 32.

  Further, the flying object protection equipment 20 is provided with a seismic isolation mechanism including a steel sliding bearing 48 and a rubber bearing 34 between the covering unit 30 and the large beam 28 and the room 11, so that the flying object protection equipment 20 can be installed in the room 11. The transmission of force to the wall surfaces 12, 14, 16, 18 can be suppressed. Thereby, even if a facility shakes due to an earthquake or the like and the room 11 vibrates, the force acting between the flying object protection equipment 20 and the room 11 can be reduced due to the vibration. Thereby, the influence which it has on the intensity | strength of the room 11 which is an existing structure can be made small. Thereby, the equipment which protects the fall of a flying object can be provided, reducing the influence which it has on the existing structure. Moreover, since the influence which it has on the existing structure can be reduced, the reinforcement required for the structure can be reduced by providing the flying object protection equipment 20. Further, since the force acting between the flying object protection equipment 20 and the room 11 can be reduced, the strength necessary for the flying object protection equipment 20 can also be reduced, and the large beam 28 and the like can be reduced.

  Moreover, the flying object protection equipment 20 of this embodiment can protect the falling object from falling while keeping the air circulated by closing a predetermined area using the net 44 in the covering unit 30. Thereby, the heat radiation from the inside of the room 11 can be suitably performed, and the temperature rise can be suppressed. Moreover, it is preferable to arrange | position the net | network 44 in the position away only by the distance which does not contact the protection target apparatus 10, even if the net | network 44 bends, when the steel pipe or steel timber etc. which are assumed as a flying object fly. Further, the net 44 has a strength that prevents the flying object from falling into the room 11 even when the flying object comes.

  Further, since the flying object protection equipment 20 can obtain the above-mentioned effects and the weight is reduced, it is preferable to use the net 44. However, instead of the net 44, a plate-like member such as a metal plate or a plastic plate is used. It may be used.

  Here, although the flying object protection equipment 20 of this embodiment provided the rubber bearing 34 and the steel sliding bearing 48 as a seismic isolation mechanism, a seismic isolation mechanism is not limited to this. If the displacement of the covering portion can be suppressed, a slidable structure combining the plate portion and the rotating body may be used instead of the steel sliding bearing 48. The structure for supporting the large beam 28 is preferably a rubber bearing 34 as in the present embodiment.

  Further, in the flying object protection apparatus 20 of the present embodiment, two brackets and rubber supports 34 for supporting the large beam 28 are provided on one wall surface, but the number is not limited. One may be sufficient and two or more may be sufficient. Two rubber supports may be installed on one bracket, or one rubber support may be installed on two brackets.

  Moreover, it is preferable that the flying object protection equipment 20 fixes each part to be fixed by a detachable mechanism such as screwing. Thereby, it can be made detachable easily and the upper surface of the room 11 can be opened at the time of maintenance. Thereby, it can suppress that the existing function reduces rather than the case where a building etc. are stood.

  Next, the installation method of the flying object protection equipment 20 is demonstrated using FIG. FIG. 7 is a flowchart showing an example of a method for installing the flying object protection equipment. The process shown in FIG. 7 can be executed by an operator using various heavy machines. First, the worker installs a bracket on the wall surface (step S12). Next, the worker installs a rubber bearing on the upper surface of the bracket (step S14). Next, the worker installs a large beam on the rubber bearing (step S16). After installing the girder, the worker installs the covering unit (step S18), and then installs the connecting unit (step S20).

  The flying object protection equipment 20 can be installed as described above. Note that the flying object protection equipment 20 may be fixed in advance to the covering unit 30 to which the connection unit 32 is fixed. In this case, the covering unit 30 and the connecting unit 32 can be installed at a time.

  The flying object protection equipment 20 has a structure in which one of the covering units 30 is fixed to the large beam 28 and the other is supported by the wall surface, but is not limited thereto. The flying object protection equipment 20 can change the number of the large beams 28, adjust the position of the bracket, or change the structure of the seismic isolation mechanism according to the conditions of the room 11 in which the flying object protection equipment 20 is installed. The flying object protection equipment 20 may have a structure in which members other than the bracket are connected to the room 11 via the seismic isolation mechanism.
