The holder 60 is fixed to the bottom surface of the upper staircase 20, and has a plurality of receiving grooves 61 are disposed facing the staircase layers (11, 11 ') of the lower staircase 10, respectively. Here, the receiving groove 61 is formed long in the longitudinal direction of the staircase layers 11 and 11 ', and the firewall 70 is movable inwardly.

Since the holder 60 is fixed to the bottom of the upper staircase 20, it should be disposed at a sufficient height so as not to collide with the head of the pedestrian passing through the lower staircase 10, and at a constant distance from the bottom of the upper staircase 20. It must be formed to protrude. In addition, since the firewall 70 accommodated in the receiving groove 61 should be able to move horizontally along the guide bars 50 and 50 ', the firewall 70 should also be stored horizontally. As a result, the storage box 60 should have a shape in which the stairs are reversed in the reverse direction.

The seating table 40 is disposed to face the receiving groove 61, and when the firewall 70 drawn out of the receiving groove 61 moves along the guide bars 50 and 50 ', the seating table 40 So that they can be engaged correctly.

To this end, the seat 40 has a fitting groove 41 having an upper surface, and a side groove 42 into which the lower insert 52 of the guide bars 50 and 50 'is engaged with and inserted into both sides. On the upper surface of the fitting groove 41, a magnetic body 43 for holding and fixing the dropped firewall 70 is seated.

The guide bars 50 and 50 ′ are disposed parallel to both sides of the receiving groove 61 and both sides of the fitting groove 41, respectively, and serve as railings between the upper stairs 20 and the lower stairs 10. In the meantime, it guides the movement of the firewall 70 drawn from the receiving groove 61 in case of emergency so that it can be accurately seated in the fitting groove 41 of the seat 40.

To this end, a pair of guide lines 51 protruding from each other are formed on both side surfaces of the guide bars 50 and 50 ', and both sides of the firewall 70 are engaged with each other between the guide lines 51.

On the other hand, the guide bar (50, 50 ') is assembled as the following shape and structure for a more secure fixing.

Both ends of the guide bar (50, 50 ') should be of a shape suitable for engagement with the staircase structure, such as the lower staircase 10 and the storage box 60, the guide bar (b) at the boundary between neighboring staircases (11, 11') In order to increase the binding force of the 50 and 50 ', the guide bars 50 and 50' must be of a structure that can be engaged with all of the neighboring stair layers 11 and 11 '. To this end, the lower insertion portion 52 of the guide bar (50, 50 ') is provided with an engaging groove (52a) cut into a length corresponding to the height of the staircase layer (11, 11'), the upper insertion portion ( 53 is provided with an engaging groove 53a cut into a length corresponding to a distance away from the neighboring storage groove 61, and as shown in FIG. 3, the stairs to which the guide bars 50 and 50 'are adjacent. It is firmly engaged with the layers 11 and 11 'and the receiving groove 61 so as to be fixed.

Of course, guide lines 51 and 51 'respectively formed on the front and rear surfaces of the guide bars 50 and 50' will not be provided in the engagement grooves 52a and 53a.

On the other hand, the lower insertion portion 52 of the guide bar (50, 50 ') is engaged with the side groove 42 of the seating table 40, the guide bar (50, 50') is a lower staircase (10), It is tightly coupled with the storage box 60 and the seating table 40.

Figure 4 is an exploded perspective view showing the appearance of the firewall according to the present invention, will be described with reference to this.

The firewall 70 is accommodated in the receiving groove 61, in the case of falling down along the guide bar (50, 50 ') in the case of making a wall between the upper staircase 20 and the lower staircase 10, This makes it possible to minimize the spread of flames and toxic gases through emergency exits.

To this end, the firewall 70 has a plurality of panels (71, 71 ') is rotatably fixed through the rotation axis 76, the end is provided with a magnetic body 74 corresponding to the magnetic body 43, The firewall 70, which has fallen completely, is not easily separated by the magnetic force between the magnetic bodies 43 and 74.

The magnetic body 74 and the panel 71 are rotatably coupled while the rotating shaft 76 penetrates through the rotation grooves 73 and 73 'provided in each of them, and at this time, between the magnetic body 74 and the panel 71 The engagement is via a linker 75 with a gripper 75a. The gripper 75a has a round ring shape, and rotatably surrounds the rotary tables 74a respectively formed at both ends of the magnetic body 74. The linker 75 is rotatably coupled to the panel 71 via the rotation grooves 73 and 73 '.

On the other hand, the gripper 75a protrudes toward the magnetic body 74 to form a locking hole 75b at the center thereof. The locking hole 75b is to engage the stopper 62 in the holder 60, which will be described in more detail below.

5 is a partial cross-sectional view showing the operation of the firewall, it will be described with reference to this.

The firewall 70 is movably received in the receiving groove 61, and the magnetic body 74 is disposed at a position that can be inserted between the guide lines 51. That is, when the magnetic body 74 falls under the load, the magnetic material 74 moves downward while being inserted into the guide line 51, and the panel 71 and 71 ′ connected to the linker 75 move by the upper layer stairway 20. And the lower staircase 10 is closed.

By the way, the movement of the firewall 70 is normally prevented to be accommodated in the accommodating groove 61, and in case of emergency, the firewall 70 should be able to fall quickly along the guide bar 50. To this end, the interlayer firewall facility according to the present invention is rotatably fixed to the storage box 60 while one end is fixed to the engaging hole (75b) and the other end is supported by the brace 63.

In more detail, the stopper 62 is rotatably fixed to one point of the storage box 60 on the linker 75 via the pivot shaft 62a, and one end and the other end of the stopper 62 are rotated. It becomes a right angle with respect to the rotating shaft 62a. Accordingly, one end of the stopper 62 is vertically protruded to engage the catching hole 75b of the linker 75 located below, and the other end is protruded horizontally, and the bottom surface thereof is supported by the brace 63. As a result, the brace 63 is pressed by the other end of the stopper 62 while supporting it to stop the rotation of the stopper 62, and one end of the stopper 62 is engaged with the engaging hole 75b of the linker 75. Support it and stop its movement.

Then, in the event of a fire, the other end of the stopper 62 is rotated about the rotation shaft 62a without receiving any more support by pulling the prop 63 and moving horizontally, together with the stopper for supporting the linker 75. As one end of 62 is rotated, the firewall 70 is no longer subject to its movement. As a result, the firewall 70 is inserted and moved between the guide lines 51 while falling from the magnetic material 74 to the load, and the panels 71 and 71 'connected to the linker 75 move along the guides. Move down along bar 50.

In this case, the widths of the panels 71 and 71 ′ are narrower than the widths between the guide lines 51 of the neighboring guide bars 50 and 50 ′, and thus may operate as shown in FIG.

However, when the widths of the panels 71 and 71 'become smaller than the widths between the guide lines 51 of neighboring guide bars 50 and 50', the flame or toxic gas is generated by the guide lines 51 and the panels 71 and 71. You can pass between '). Therefore, the emergency staircase structure according to the present invention includes a barrier film 78 for minimizing the gap between the panels 71 and 71 'and the guideline 51.

The breaking film 78 is mounted in the receiving groove 77 cut in such a manner that both sides of the panel are opened, and is movably fixed to the pair of rotating pieces 79 and 79 'having a pair of rotating holes.

In order to explain this in more detail, reference is made to FIG.

The blocking film 78 has a shape corresponding to the receiving groove 77, one of the pair of rotating holes is fixed through the receiving groove 77 and the torsion spring shaft 79a and the other is the blocking film 78. 6A and 6B are rotatably fixed by a pair of rotating pieces 79 and 79 'which are rotatably fixed thereto.

Here, it is preferable that one side of the blocking film 78 constitutes a locking groove 78a in which a part thereof is cut in consideration of operation as shown in FIG. 6 (b).

FIG. 6 (a) shows when the panel 71 is in the receiving groove 61. The panel 71 is blocked by both side walls of the receiving groove 61 so that the blocking film 78 does not protrude from the receiving groove 77. As shown in FIG. It is a state. FIG. 6 (b) shows when the panel 71 is in the guide bar 50. As the panel 71 is vertically disposed, the blocking film 78 is accommodated by the rotational force of the torsion spring shaft 79a. The gap between the panel 71 and the guideline 51 is filled while protruding from the groove 77.

Subsequently, the brace 63 moves horizontally through the moving table 63a which is interlocked with the driving unit (not shown). That is, in case of emergency fire alarm is activated, the driving unit which interlocks with it pulls the movable base 63a to separate the brace 63 from the stopper 62. An interlocking structure of the driving unit and the movable table 63a for moving the movable table 63a may be various, such as a crank method and a screw method.

First, in the case of the crank method, the movable table 63a is connected to the disk (not shown) of the driving unit that rotates so that the movable table 63a makes a linear motion when the disk rotates.

Next, in the screw method, a screw thread is formed on an outer circumferential surface of the movable table 63a, and the movable table 63a is engaged with a nut (not shown) of the driving unit to which the movable table 63a rotates. ) Is to make a linear motion.

Since the linear movement of the movable table 63a can be realized in various other forms, it may be modified in various ways without departing from the scope of the following claims.

The drawing number “72”, which is not described, is a shielding film, which covers the boundary between the linker 75 and the panel 71 and the panel 71 and the panel 71 ′, thereby minimizing the gap formed at the boundary to close the firewall 70. To secure. To this end, the shielding film 72 protrudes to cover the upper side of the rotation groove 73 located in one direction from the upper surfaces of the panels 71 and 71 '.

According to the present invention as described above, the space between the upper staircase and the lower staircase can be quickly closed to prevent the spread of fire through the emergency exit, it is economical in its maintenance, and can be easily installed in an existing building. There is an effect that can be utilized.
