In addition, in this specification, a loan evacuation gang and a refuge evacuation gang are integrated.

A frame 10 constituting a swing door for the loan,

Although it has a door panel 20 constituting a sliding door for the person, the protection scope of the present invention should not be limited interpretation.

1A and 1B and FIG. 2, the upper horizontal beam 13A of the frame is provided with a rail 13a so that the roller 23 of the door panel 20 is mounted to support the load in the hanger type. Move around,

The lower horizontal beam 13B is provided with a rail 13b for guiding the door panel 20 and preventing separation.

Above and below one of the vertical beams 11A is provided with a hinge shaft 11S coupled to the member of the evacuation tunnel serving as a door frame.

In addition, as shown in Figure 1B, a locking member 17 for fixing the closed swing-type frame 10 is provided in one of the vertical beam (11B),

The locking member 17 includes a fixed rod 17A and a guide pipe 19,

The fixed rod 17A, which is raised (opened position) or lowered (closed position), may be lodged in a fixed ball (not shown) provided on the ground.

The fixing rod 17A moving along the guide pipe 19 mounted on the vertical beam 11B of the frame 10 is lifted when opened, and the mounting protrusion 17a of which the handle portion 17a is fixed to the vertical beam 11B. It is preferable to settle in 18) and to prevent arbitrary fall.

Meanwhile, as shown in FIG. 1C, a spiral cut 19a is formed at an upper end of the guide pipe 19 as a modification.

The handle portion 17a of the fixing rod 17A, in particular the bent portion 17b, is restrained

When the fixing rod 17A is lowered after the closing of the frame 10 constituting the swing type gang door.

The bent portion 17b of the handle portion 17a is restrained and descends while turning along the spiral cutout portion 19a.

The handle portion 17a, which has faced the front face at the initial entry of the spiral cutout portion 19a, is directed to the side in the direction toward the vertical beam 11A.

Such a change in direction of the handle portion 17a is constrained by overlapping with the handle portion 17a, at least the bent portion 17b, on which the guide pipe 19 is thick so that the cross-section portion 19c constituting the cutout portion 19a descends. Because of

In consideration of material savings and the like, the thick cross-section 19c may be introduced by an additional tooth (or a substitute of a guide of different materials) rather than the thickness of the pipe 19 itself.

In addition, in order to facilitate the entry of the handle portion 17a into the spiral cut portion 19a, it is preferable that the cut portion has a wide opening portion 19b that gradually narrows.

As such, the operation of changing the direction toward the side of the handle portion 17a of the fixed rod 17A having completed the lowering has an insertion fixing portion 27 and the handle portion 17a provided in the door panel 20 sliding and opening. To be mutually coupled,

The reason for this is that when the swing of the frame 10 is first opened, the door panel 20 must be opened to release the handle 17a of the fixing rod 17A, which has been restrained by the insertion fixing part 27, and thus the As it can be raised, the frame can be opened

When the door panel 20 is closed, the gang door is impacted by a sudden strong wind, and the evacuation or worker injury may occur.

This is because the frame 10 is swing-opened after the door panel 20 is slid open to a certain extent, so that the wind pressure can be released through the open gap and the wind pressure can be eliminated, thereby preventing a sudden movement.

The wind pressure relief function through the spiral cutout 19a of the locking member 17 and the guide pipe 19 and the insertion fixing portion 27 of the door panel 20 is an evacuation shaft door type into which the deceleration means 40 described later is introduced. In the can be assisted with the function of the deceleration means.

In addition, even when the frame 10 is moved to the closed position, the door panel 20 must be opened in order to completely lower the fixing rod 17A of the locking member 17,

When strong wind occurs before the fixing rod is engaged with the fixing hole provided on the ground

Since the door panel 20 is opened in advance, the wind pressure can be eliminated.

By bowing, you can prevent injured evacuees or workers from hitting the frame.

After the lowering of the fixed rod 17A and the handle portion 17a (particularly the bent portion 17b) that descends along the guide pipe 19 and the spiral cutout portion 19a, the door panel 20 that is open is closed. Insertion fixing portion 27 is fitted to the handle portion 17a to be prepared for the next opening,

In order to avoid embarrassment of emergency refugees during disasters, the opening order should be clearly and clearly communicated through pictures and notices.

If derailment of the door panel 20 occurs, a situation in which the evacuation function cannot be exerted in the event of a disaster occurs.

Such a separation prevention member is preferably arranged in the closed position of the door panel,

In general, since a derailment is more likely to occur at the lower rail side than the upper rail of the frame due to the characteristics of the door panel installed by the sliding hanger door method, the departure preventing member 30 is attached to the lower horizontal beam 13A of the frame 10. It is provided.

Furthermore, as shown in the drawing, it is preferable that the door panel 20 slidingly opened and closed along the rails 13a and 13b of the frame 10 is configured in multiple stages to enlarge the open area.

In this case, it is preferable that the separation preventing member 30 is arranged at both sides of the mutual overlapping portions 20A of the closed door panel 20.

The separation preventing member 30 is preferably introduced in a form in which a metal piece is fixed to the lower horizontal beam 13B by bolts in consideration of ease of manufacture.
