The specific configuration of the first movement limiting unit 60 and the second movement limiting unit 70 is arbitrary, but in the embodiment, the opening / closing body 20 is warped in the expected direction (hereinafter referred to as “expected side warp”). Regardless of whether or not (referred to as) occurs, the movement of the opening / closing body 20 can be restricted by the first movement limiting unit 60 and the second movement limiting unit 70 in the fully closed state.

Here, the “expected side warp” means that, in the embodiment, the end portion of the opening / closing body 20 on the orthogonal finding direction side (the upper end portion or the lower end portion of the opening / closing body 20 in FIG. 1) is opened / closed due to an external factor. It means that the body 20 is warped so as to project outside the prospective direction (specifically, the outdoor side of the room (that is, the opening direction side of the opening / closing body 20)) from the central portion on the orthogonal finding direction side. .. Further, the "external factor" includes, for example, the difference in the amount of sunlight irradiation between the outdoor portion and the indoor side portion of the room of the opening / closing body 20, the difference between the outdoor temperature of the room and the indoor temperature, and the like. Applicable.

Is arranged (configured).

As for the second movement limiting portion 70, as shown in FIG. 6B, the second engaging portion 71b is only the first distance D1 from the outdoor side finding surface of the opening / closing body 20 toward the inside in the front-rear direction. The second lock body 71 is arranged (configured) so as to be located apart from each other (that is, the second engaging portion 71b is substantially the same position as the first engaging portion 61d in the prospective direction). Further, as shown in FIG. 8, the second engaged portion 72b is located at a distance of a third distance D3 (a distance shorter than the second distance D2) from the door-to-door side mating surface 12a toward the indoor side of the room.

It will be set longer than the gap G1 between the engaging portion 61d and the first engaged portion 62b (hereinafter, referred to as "first gap G1"). As a result, the second engaging portion 71b is inserted into the second receiving side as in the case where the expected side warp occurs when the length of the second gap G2 shown in FIG. 9 is the same as the length of the first gap G1. Since it cannot be inserted through the mouth 72c, it is possible to prevent the opening / closing body 20 from being unable to be restricted by the second movement limiting unit 70 in the fully closed state. That is, even when the expected side warp occurs (provided that the amount of the expected side warp is within the difference amount between the second gap G2 and the first gap G1), the second engaging portion 71b is received second. Since it can be inserted through the side insertion port 72c, the movement of the opening / closing body 20 can be restricted by the first movement limiting unit 60 and the second movement limiting unit 70.

A portion 12b that comes into contact with the joint portion 71b (in FIG. 4, a portion of the door end side vertical frame member 12 from the door end side mating surface 12a to the second engaging portion 71b; hereinafter, referred to as a “contact portion 12b”. ) Is preferably set so that the second engaging portion 71b can be appropriately rotated.

Due to the first feature as described above, the movement of the opening / closing body 20 can be restricted by the first movement limiting unit 60 and the second movement limiting unit 70 in the fully closed state regardless of whether or not the expected side warp has occurred. Therefore, regardless of whether or not the expected side warp has occurred, either the indoor side or the outdoor side of the room is maintained while maintaining the usability of the first movement limiting unit 60 and the second movement limiting unit 70 in the normal state. When a fire breaks out in, it is possible to prevent the fire from spreading from one side to the other in the expected direction via the switchgear 1 in the fully closed state, and it is possible to improve the usability and fire resistance of the switchgear 1. can. Further, since the first movement limiting unit 60 and the second movement limiting unit 70 are configured so that the first limiting position LP1 and the second limiting position LP2 are different from each other in the prospective direction, the second limiting position LP1 and the second limiting position LP2 are configured according to the expected side warp. 1 Restriction position LP1 and 2nd restriction position LP2 can be set, and when the prospect side warp occurs, the movement of the opening / closing body 20 is effectively restricted by the first movement restriction unit 60 and the second movement restriction unit 70 in the fully closed state. can. Further, whether or not the expected side warp occurs only by configuring the second lock receiving portion 72 so that the second engaged portion 72b is located on the opening direction side of the first limiting position LP1 in the fully closed state. Regardless of this, the movement of the opening / closing body 20 can be restricted by the first movement limiting unit 60 and the second movement limiting unit 70 in the fully closed state, and the manufacturability of the second movement limiting unit 70 can be improved.

The material of the heat shield portion 120 on the support side is composed of a heat-expanding refractory member (for example, Fiblock (registered trademark), etc.), but the material is not limited to this, for example, a heat-expanding refractory member, a glass wool material. , Urethane material and other heat-shielding materials may be used.

Due to such a support-side heat shield 120, when the fire occurs in the fully closed state, a part of the overlapping outdoor lower lateral force bone 34a and a part of the indoor lower lateral force bone 34b are mutually interleaved. When the lower lateral force bone 34 is formed of a plurality of members, it is easy to prevent the heat of the fire from being conducted from one of the prospective directions to the other through the opening / closing body 20. Become.

Due to the heat shield structure on the lower side as described above, when the fire occurs in the fully closed state, the heat of the fire is generated by the heat shield unit 100 on the surface side, the heat shield unit 110 on the closing side, and the heat shield unit 120 on the support side. Can suppress conduction from one of the prospective directions to the other via the opening / closing body 20, so that the heat shielding performance of the opening / closing body 20 can be further improved.

(Action of opening / closing body)
The operation of the opening / closing body 20 configured in this way will be described. The action of the opening / closing body 20 is largely divided into an action when a fire does not occur (hereinafter referred to as "normal action") and an action when a fire occurs (hereinafter referred to as "fire action"). Since they are separated, each action will be described below.

(Action of opening / closing body-normal action)
First, the normal operation will be described.

For example, when the position of the opening / closing body 20 is changed from the fully open position (or the half-open position) to the fully closed position when the opening / closing body 20 is not warped on the expected side, the first engaging portion 61d of the first movement limiting portion 60 The movement of the opening / closing body 20 is restricted by the first movement limiting unit 60 by the loading / unloading operation and the loading / unloading operation of the second engaging portion 71b of each of the one-side second movement limiting unit 70a and the other side second movement limiting unit 70b. At the same time, the movement of the opening / closing body 20 is restricted by the one-side second movement limiting unit 70a and the other-side second movement limiting unit 70b.

After that, when the movement restriction release operation of the first movement restriction unit 60 is performed via the first room outside operation unit 61b (or the first room side operation unit 61c) of the first movement restriction unit 60, the first movement restriction is performed. The movement restriction of the opening / closing body 20 by the unit 60 is released. Further, since the movement restriction operation of each of the one-sided second movement limiting unit 70a and the other side second movement limiting unit 70b is performed via the first interlocking unit and the second interlocking unit, the one-sided second movement restriction unit 70b is performed. The movement restriction of the opening / closing body 20 is released by the portion 70a and the second movement restriction portion 70b on the other side.

On the other hand, for example, when the opening / closing body 20 is warped on the expected side and the position of the opening / closing body 20 is changed from the fully open position (or the half-open position) to the fully closed position, the length of the second gap G2 becomes the expected side warp. Although it is shorter than the case where it does not occur, the operation of putting in and out the first engaging portion 61d of the first movement limiting unit 60 and the second movement on one side are the same as in the case where the expected side warp does not occur in the opening / closing body 20. The movement of the opening / closing body 20 is restricted by the first movement limiting unit 60 and the second movement restriction on one side is restricted by the movement of the second engaging portion 71b of each of the limiting portion 70a and the second movement limiting portion 70b on the other side. The movement of the opening / closing body 20 is restricted by the portion 70a and the second movement limiting portion 70b on the other side.

After that, when the movement restriction release operation of the first movement restriction unit 60 is performed via the first room outside operation unit 61b (or the first room side operation unit 61c) of the first movement restriction unit 60, the opening / closing body 20 is subjected to the operation. As in the case where the expected side warp does not occur, the movement restriction of the opening / closing body 20 is released by the first movement limiting unit 60, and the opening / closing is opened / closed by the one side second movement limiting unit 70a and the other side second movement limiting unit 70b. The movement restriction of the body 20 is lifted.

Regardless of whether or not the expected side warp occurs due to such normal operation, the first movement limiting unit 60, the one-side second movement limiting unit 70a, and the other side second movement limiting unit 70b in the fully closed state. The movement of the opening / closing body 20 can be restricted by the above.

(Action of opening / closing body-Action in case of fire)
Next, the action in case of fire will be described. The action during a fire is roughly divided into the action when a fire breaks out in the room and the action when a fire breaks out outside the room. Only the action in the event of a fire outside the room will be described.

For example, in a fully closed state, and in a state where the movement of the opening / closing body 20 is restricted by the first movement limiting unit 60, the one-side second movement limiting unit 70a, and the other side second movement limiting unit 70b, the room. When a fire breaks out on the outdoor side, the heat of the fire heats the outdoor surface material 40a.

In this case, even if the expected side warp is to occur in the opening / closing body 20 (or even if the expected side warp is to be increased), as described above, the first movement limiting unit 60, the one-sided second movement limiting unit 70a, Since the movement of the opening / closing body 20 is restricted by the second movement limiting unit 70b on the other side, the occurrence of the expected side warp (or the increase in the expected side warp) is suppressed.

Further, a part of the heat of the fire tries to be directly conducted from the outdoor surface material 40a toward the indoor surface material 40b, or from the outdoor surface material 40a to the door tail side longitudinal force bone 31, the door end. When an attempt is made to indirectly conduct toward the indoor surface material 40b via each of the lateral longitudinal force bone 32, the upper lateral force bone 33, the lower lateral force bone 34, and the intermediate longitudinal force bone 35, the first prospective surface Side heat shield 81, 1st room outside heat shield 82, 1st room side heat shield 83, 2nd room outside heat shield 91, 2nd room side heat shield 92, surface side heat shield 100, closing By the side heat shield 110 and the support side heat shield 120, the outdoor surface material 40a, the door tail side longitudinal force bone 31, the door end side longitudinal force bone 32, the upper lateral force bone 33, the lower lateral force bone 34, And each of the intermediate longitudinal force bones 35, the door tail side longitudinal force bone 31, the door tip side longitudinal force bone 32, the upper lateral force bone 33, the lower lateral force bone 34, and the intermediate longitudinal force bone 35, respectively. Heat conduction between the surface material 40b on the indoor side and between the surface material 40b on the indoor side and between the lateral force bone 34 on the lower side and the closing portion 22 is suppressed.

Regardless of whether or not the expected side warp is caused by such a fire action, the opening / closing body 20 is formed by the first movement limiting unit 60, the one-side second movement limiting unit 70a, and the other side second movement limiting unit 70b. It is possible to limit the movement of the fire and prevent the fire from spreading from the outside of the room to the inside of the room via the switchgear 1.

(Effect of embodiment)
As described above, according to the embodiment, the closing portion 22 attached to the lower lateral force bone 34, the closing portion 22 for closing the prospective surface side gap PG in the fully closed state, and the outdoor surface material. Since the surface side heat shield portion 100 for suppressing heat conduction between at least one of the 40a or the indoor side surface material 40b and the lower lateral force bone 34 is provided, the expected direction in the fully closed state. In the event of a fire on either side, heat conduction between the outdoor surface material 40a or the indoor surface material 40b and the lower lateral force bone 34 can be suppressed. Therefore, it becomes easy to prevent the heat of the fire from being conducted from one of the prospective directions to the other via the opening / closing body 20, so that the heat shielding property of the opening / closing body 20 can be improved.

Further, the surface side heat shield portion 100 suppresses heat conduction between the outer side surface material 40a or the indoor side surface material 40b on the finding surface side and the lower lateral force bone 34. The second surface side shield for suppressing heat conduction between the surface side heat shield portion 101, the part on the prospective surface side of the outdoor side surface material 40a or the indoor side surface material 40b, and the lower lateral force bone 34. Since the heat portion 102 is provided, the outdoor side is provided when a fire occurs in a fully closed state, as compared with the case where only one of the first surface side heat shield portion 101 and the second surface side heat shield portion 102 is provided. It is possible to suppress heat conduction between the surface material 40a or the indoor surface material 40b and the lower lateral force bone 34, and the heat of the fire is conducted from one side to the other through the opening / closing body 20. It will be easier to avoid.

Further, since the thickness of the first surface side heat shield portion 101 is made thicker than the thickness of the second surface side heat shield portion 102, the thickness of the first surface side heat shield portion 101 is changed to the thickness of the second surface side heat shield portion 102. Compared to the case where the thickness is thinner than 102, heat conduction between the outdoor surface material 40a or the indoor surface material 40b and the lower lateral force bone 34 when the fire occurs in the fully closed state. The amount of the second surface side heat shield 102 installed can be reduced while being effectively suppressed, and the material cost of the second surface side heat shield 102 can be reduced while ensuring the heat shield of the opening / closing body 20.

Further, since the second surface side heat shield portion 102 is a thermal expansion fire resistant member, when the fire occurs in a fully closed state, the outdoor surface material 40a is provided by the thermal expansion fire resistant member thermally expanded by the heat of the fire. Alternatively, in addition to closing the gap between the indoor side surface material 40b and the lower lateral force bone 34, it is also possible to close the prospective surface side gap PG. Therefore, even if the closing portion 22 cannot close the gap PG on the prospective surface side, it is possible to prevent the fire from spreading from one side to the other in the prospective direction through the gap PG on the prospective surface side.

Further, since the closing side heat shielding portion 110 for suppressing heat conduction between the closing portion 22 and the lower lateral force bone 34 is provided, the closing portion 22 and the closing portion 22 are provided when the fire occurs in the fully closed state. Heat conduction between the lower lateral force bone 34 can be suppressed, the function of the closing portion 22 can be suppressed from being deteriorated by the heat of the fire, and the heat of the fire can suppress the closing portion 22 and the lower lateral force bone. It becomes easy to avoid conducting in either one of the prospective directions via 34.

Further, since the support side heat shield 120 for suppressing heat conduction between a part of the overlapping outdoor lower lateral force bone 34a and a part of the indoor lower lateral force bone 34b is provided, it is fully closed. When the fire occurs in the state, heat conduction between a part of the overlapping outdoor lower lateral force bone 34a and a part of the indoor lower lateral force bone 34b can be suppressed, and the lower lateral force bone can be suppressed. When the 34 is formed of a plurality of members, it becomes easy to prevent the heat of the fire from being conducted from one of the prospective directions to the other via the opening / closing body 20.

Further, since at least a part of the lower lateral force bone 34 is formed in a concave shape that can accommodate a part of the closing portion 22, a part of the closing portion 22 can be stored in the concave portion 34g of the lower lateral force bone 34. , It is possible to prevent the closing portion 22 from being exposed to the outside.

According to the opening / closing body for the fireproof door described in Appendix 2, the surface-side heat-shielding means is between the first surface material and / and the portion of the second surface material on the finding surface side and the prospective surface-side supporting member. Heat conduction between the first surface side heat shield means for suppressing heat conduction in the first surface material and / and the prospective surface side portion of the first surface material and / and the second surface material and the prospective surface side support member. Since it is provided with a second surface-side heat-shielding means for suppressing the heat, a fire can occur in a fully closed state as compared with the case where only one of the first surface-side heat-shielding means and the second surface-side heat-shielding means is provided. When it occurs, heat conduction between the first surface material or the second surface material and the prospective surface side support member can be suppressed, and the heat of the fire is conducted from one of the prospective directions to the other through the opening / closing body. It becomes easier to avoid that.

According to the opening / closing body for the fireproof door described in Appendix 3, the thickness of the first surface-side heat-shielding means is made thicker than the thickness of the second surface-side heat-shielding means. Compared to the case where the thickness is made thinner than the thickness of the second surface side heat shield means, when the fire occurs in the fully closed state, the first surface material or the second surface material and the prospective surface side support member interact with each other. It is possible to reduce the amount of the second surface side heat shield means installed while effectively suppressing heat conduction between them, and to reduce the material cost of the second surface side heat shield means while ensuring the heat shield property of the opening / closing body. ..

According to the opening / closing body for the fire door described in Appendix 4, since the second surface side heat shield means is a thermal expansion fire resistant member, when the above fire occurs in the fully closed state, the heat of the fire causes heat. In addition to closing the gap between the first surface material or the second surface material and the prospective surface side support member by the expanded thermal expansion fire resistant member, it is also possible to close the prospective surface side gap. Therefore, even if the gap on the prospective surface side cannot be closed by the closing means, it is possible to prevent the fire from spreading from one side to the other in the prospective surface side through the gap on the prospective surface side.

According to the opening / closing body for the fire door described in Appendix 5, the closing side heat shielding means for suppressing heat conduction between the closing means and the prospective surface side support member is provided. When a fire breaks out, heat conduction between the closing means and the prospective surface side support member can be suppressed, and the heat of the fire is conducted to either one of the prospective directions via the closing means and the prospective surface side support member. It becomes easier to avoid doing.

According to the opening / closing body for the fire door described in Appendix 6, in order to suppress heat conduction between a part of the overlapping first prospective surface side support member and a part of the second prospective surface side support member. Since the support side heat shielding means is provided, when the fire occurs in the fully closed state, between a part of the overlapping first prospective surface side support member and a part of the second prospective surface side support member. When the prospective surface side support member is formed of a plurality of members, it becomes easy to prevent the heat of the fire from being conducted from one of the prospective directions to the other through the opening / closing body.

According to the opening / closing body for the fire door described in Appendix 7, at least a part of the prospective surface side support member is formed in a concave shape that can accommodate a part of the closing means, so that a part of the closing means is formed on the prospective surface side. It can be stored in the concave portion of the support member, and it is possible to prevent the closing means from being exposed to the outside.
