In the conventional explosives handling equipment unit, it is general that an eave covered with a metal plate, for example, against a wooden frame is provided at the upper part of the door portion. This eave is fixedly provided in advance on the wall or roof of the explosives handling equipment unit, and the overhang length of the eave is about 450 mm to 500 mm. Therefore, when the conventional explosives handling equipment unit is transported to the site by vehicle, the overhang of the eaves may become an obstacle. In addition, when constructing the explosives handling equipment unit at the site, the weight of the eaves is heavy, so it is difficult to maintain the balance of the explosives handling equipment unit, and there is also a problem that the construction work of the explosives handling equipment unit is difficult. .. On the other hand, as in this embodiment, by providing the explosives handling equipment unit 1 with the roll screen 19, the overhang length can be suppressed, so that the explosives handling equipment unit 1 can be easily transported. can. Further, since the weight of the roll screen 19 is relatively light, when the explosives handling equipment unit 1 is built on site, the construction work can be performed while maintaining the balance of the explosives handling equipment unit 1, and the work efficiency is higher than before. It will be good.

Further, as in this embodiment, the screen 192 can be pulled out from the roll screen 19 and the hook portion 194 of the weight bar 193 at the tip end portion of the screen 192 can be fixed to the outer fence 5 to block direct sunlight. can. Therefore, for example, even on a day with strong sunlight in summer, the temperature in the vicinity of the door portion 15 can be suppressed, and as a result, the indoor temperature can be suppressed and the working environment can be improved.

Further, the conventional explosives handling equipment unit is provided with an eave with an overhang length of about 450 mm to 500 mm, but when it rains, the explosives possessed by the workers entering and exiting the explosives handling equipment unit get wet with rain. There was a case that it ended up. Therefore, as in this embodiment, the screen 192 is pulled out from the roll screen 19 and the hook portion 194 of the weight bar 193 is fixed to the fixed portion 51 of the outer fence 5, so that the door portion 15 and the outer fence, which are entrances and exits, are fixed. Since the space between 5 and 5 (about 1 m to several m) can be covered with the screen 192, it is possible to prevent the explosives possessed by the workers entering and exiting from getting wet with rain.

In this embodiment, the case where the roll screen 19 is provided on the upper part of the door portion 15 is illustrated, but the present invention is not limited to this. For example, the roll screen 19 may be provided at a position facing the door portion 15 in the outer fence 5 provided around the explosives handling equipment unit 1. In this case, when the roll screen 19 provided on the outer fence 5 is unwound, the hook portion 194 of the screen 192 may be hooked on any part of the door portion 15.

The floor portion 14 is a portion arranged below the skeleton portion 11, and a conductive underfloor member such as an iron plate panel is attached to the lower portion of the skeleton portion 11, and a wooden board or the like is also attached to the upper surface of the underfloor member. It is formed by attaching a floor member.

In the room of the explosives handling equipment unit 1, the material of the floor portion 14 must be a wooden member in order to suppress the generation of static electricity. However, even if the material of the floor portion 14 is a wooden member, if an operator performs work such as attaching a detonator to the medicine package indoors, static electricity may be generated and the member of the floor portion 14 may be charged. ..

Therefore, in this embodiment, antistatic equipment (antistatic equipment) is provided on all or part of the surface of the floor portion 14.

For example, the floor portion 14 may be formed by using an antistatic floor material having an antistatic function of static electricity as all or a part of the members. Further, for example, the antistatic paint may be applied to all or a part of the members of the floor portion 14. In this way, by providing static electricity antistatic equipment on all or part of the floor portion 14, it is possible to prevent static electricity from being charged more effectively than before.

Further, for example, a sheet member for preventing static electricity (antistatic sheet member) may be covered on all or a part of the surface of the floor portion 14. Such an antistatic sheet member can be installed or removed from the surface of the floor portion 14. Since the Explosives Control Act stipulates strict technical standards regarding the structure of explosives handling offices and pyrotechnics, it is assumed that sufficient antistatic measures cannot be taken. However, by using the antistatic sheet member, it is possible to effectively prevent the static electricity in the room of the explosives handling equipment unit 1.
