DETAILED DESCRIPTION

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in FIG. 3 , a steel structure frame type fire door wall is proposed in this embodiment, including a crossbeam 2 and a base 3, two standing columns 1 are arranged between the crossbeam 2 and the base 3, and the upper end and the lower end of the standing column 1 are fixedly connected to the crossbeam 2 and the base 3 respectively;

[0020] A fire curtain sheet 5 is provided between the two station columns 1, and both sides of the fire curtain sheet 5 are slidably connected to the station columns 1, and the upper end of the fire curtain sheet 5 is movably connected to the roller shutter 4 provided at the lower end of the beam 2, and a plug plate 6 is provided at the lower end of the fire curtain sheet 5, and the plug plate 6 is movably matched with a slot 7 provided at the upper end of the base 3; the upper end of the fire curtain sheet 5 is rolled into the roller shutter 4, and the motor in the roller shutter 4 controls the rotation of the winding roller, so that the fire curtain sheet 5 can fall from the lower end of the roller shutter 4 or be rolled up in the roller shutter 4, so that the door wall is opened. The fire curtain sheet 5 is generally made of steel, inorganic materials, etc., and can play a role in fire and smoke prevention.

[0021] The slot 7 is used to seal the waterproof valve sheet before the plug board 6 is inserted. The upper end of the base 3 is provided with a dustproof valve sheet, which is placed between the slot 7 and the plug board 6. After the fire curtain sheet 5 falls, the plug board 6 at its lower end will be inserted into the slot 7. The dustproof valve sheet arranged at the upper end of the base 3 can prevent dust from falling into the slot 7 and affecting the fit between the plug board 6 and the slot 7. The waterproof valve sheet in the slot 7 can be retracted when the plug board 6 is inserted into the slot 7. The waterproof valve sheet can prevent external water vapor from invading the slot 7, so that the slot 7 remains dry and ensures the stable fit between the plug board 6 and the slot 7.

[0022] Regarding the dustproof valve plate and the waterproof valve plate: the dustproof valve plate includes a mounting seat 14, which is fixed on the upper end of the base 3, and a baffle slot 16 is provided on the side of the mounting seat 14 facing the slot 7, and a first baffle 15 is provided in the baffle slot 16, one end of the first baffle 15 extends above the slot 7, and the other end of the first baffle 15 is fixedly connected to the first spring 17 fixed in the baffle slot 16, and the first baffle 15 is slidably connected to the baffle slot 16. The first baffle 15 pops out from the baffle slot 16 under the push of the first spring 17 and covers the top of the slot 7, and the dust falling on the outside of the base 3 will be blocked by the first baffle 15 and will not fall into the slot 7. When the fire curtain 5 falls, the plug plate 6 at the lower end of the fire curtain 5 will contact the first baffle 15, and the plug plate 6 pushes the first baffle 15 to move horizontally and retract the first baffle 15 into the baffle slot 16, and when the fire curtain 5 rises, the first baffle 15 will be reset under the push of the first spring 17.

[0023] The waterproof valve plate includes a movable slot 19 provided on the side wall of the slot 7, a second baffle 20 is provided in the movable slot 19, one end of the second baffle 20 extends into the slot 7, the other end of the second baffle 20 is fixedly connected to the second spring 18 fixed in the movable slot 19, and the second baffle 20 is slidably connected to the movable slot 19. A gap is left between the first baffle 15 and the base 3, and external water vapor will enter the slot 7 through the gap. The baffle slot 16 is provided in the slot 7 to prevent water vapor from invading the slot 7 and avoid rust in the slot 7. When the plug plate 6 is inserted into the slot 7, the plug plate 6 will push the second baffle 20 to move horizontally and retract the second baffle 20 into the movable slot 19. When the fire curtain 5 rises, the second baffle 20 will be reset under the push of the second spring 18.

[0024] When a fire occurs in the tunnel, the impact generated by the inner side of the door wall will damage the fire curtain 5. Since the plug plate 6 at the lower end of the fire curtain 5 is plugged into the slot 7, when the fire curtain 5 is impacted, the end of the fire curtain 5 in contact with the base 3 is easily opened, which is not conducive to the control of the fire.

[0025] In the preferred solution, baffle grooves 13 are provided at both ends of the base 3, the baffle grooves 13 are opened at the upper end of the base 3, and oblique baffles 10 are provided in the baffle grooves 13, and the oblique baffles 10 are movably matched with the baffle grooves 13. The ends of the two oblique baffles 10 that are close to each other are rotatably connected to the groove wall of the baffle groove 13 through a rotating pin, and the other ends of the oblique baffles 10 are detachably connected to the first positioning part provided on the front of the station column 1, and the front of the fire curtain piece 5 is provided with a second positioning part, and the second positioning part is detachably connected to the oblique baffle 10. When the fire curtain piece 5 falls completely, the oblique baffle 10 is pulled out of the baffle groove 13, and the oblique baffle 10 is rotated. The end of the oblique baffle 10 away from the rotating pin is fixed to the station column 1 through the first positioning part, and the fire curtain piece 5 is fixed to the oblique baffle 10 through the second positioning part. The oblique baffle 10 is fixed in the angle formed between the station column 1 and the base 3 to protect the fire curtain piece 5.

[0026] Regarding the first positioning part and the second positioning part: the first positioning part includes a second positioning bolt 12 and a first positioning hole 8. The first positioning hole 8 is opened on the front of the station column 1. The second positioning bolt 12 is installed at the end of the inclined baffle 10 away from the rotating pin. The second positioning bolt 12 is threadedly connected to the inclined baffle 10. The second positioning bolt 12 passes through the inclined baffle 10 and is threadedly connected to the first positioning hole 8. The first positioning part uses a bolt connection to fix the inclined baffle 10 to the station column 1. When releasing the fixation between the inclined baffle 10 and the station column 1, the second positioning bolt 12 assembled on the inclined baffle 10 can be screwed out of the first positioning hole 8.

[0027] The second positioning part includes a first positioning bolt 11 and a second positioning hole 9. The second positioning hole 9 is provided on the front of the fire curtain 5. The first positioning bolt 11 is installed in the central area of ​​the inclined baffle 10. The first positioning bolt 11 is threadedly connected to the inclined baffle 10. The first positioning bolt 11 passes through the inclined baffle 10 and is threadedly connected to the second positioning hole 9. Similar to the first positioning part, the second positioning part also adopts a bolt connection method to fix the inclined baffle 10 and the fire curtain 5. When the fire curtain 5 is completely dropped, the second positioning hole 9 provided on the front of the fire curtain 5 will be in the same position as the first positioning bolt 11 installed on the inclined baffle 10. At this time, the first positioning bolt 11 is screwed into it to complete the reinforcement of the fire curtain 5 by the inclined baffle 10.

[0028] Working principle: After the fire curtain 5 falls, the plug plate 6 at the lower end of the fire curtain 5 will be inserted into the slot 7. The dustproof valve plate arranged at the upper end of the base 3 can prevent dust from falling into the slot 7 and affecting the fit between the plug plate 6 and the slot 7. The waterproof valve plate in the slot 7 can retract when the plug plate 6 is inserted into the slot 7. The waterproof valve plate can prevent external water vapor from invading the slot 7, so that the slot 7 remains dry, ensuring the stable fit between the plug plate 6 and the slot 7.
