Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fire doors, in particular to a tunnel fire door that can be opened in both directions. Background Art
[0002] A protective door is a door that can withstand various shock waves or collisions of heavy objects. It is generally made of steel. In order to withstand the air pressure caused by the train passing through the tunnel, the internal equipment can be kept intact and not be harmed by the air pressure shock wave. Tunnel fire doors have excellent explosion-proof performance and must also be fire-resistant.
[0003] With the continuous improvement of tunnel construction requirements, today's tunnel fire doors not only need to have the above-mentioned impact resistance, explosion resistance and fire resistance, but also need to continuously improve their fire response capabilities. When a fire or other critical situation occurs, the fire location is uncertain, and a one-way opening fire door can hardly save escape time. Therefore, there is an urgent need to design a two-way opening tunnel fire door that can achieve the purpose of escape from both sides. Utility Model Content
[0004] The technical problem to be solved by the utility model is that, due to the uncertainty of the fire position in the tunnel, the escape time is relatively wasted when the fire door in the tunnel is opened on one side.
[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: The present invention proposes a tunnel two-way opening fire door, including a tunnel-mounted door frame, the middle of the tunnel-mounted door frame is wrapped with a double-sided opening protective door assembly, and two groups of symmetrical wall embedding grooves are vertically installed on both sides of the tunnel-mounted door frame, and the two groups of wall embedding grooves clamp the tunnel-mounted door frame.
[0006] As an improvement, the double-sided opening protective door assembly includes a hinged member 1, a fire door 1, a baffle 1, a hinged member 2, a fire door 2 and a baffle 2, the hinged member 1 is provided on the tunnel installation door frame, the fire door 1 is connected to the hinged member 1, and the baffle 1 extends from the side of the fire door 1 away from the hinged member 1;
[0007] The second hinge is arranged on the other side of the tunnel installation door frame, the second fire door is fixed to the second hinge, and the second baffle extends from the other side of the second fire door.
[0008] As an improvement, the baffle 1 and the baffle 2 are symmetrical, and the baffle 1 and the baffle 2 together block the gap between the fire door 1 and the fire door 2.
[0009] As an improvement, the hinge part 1 and the hinge part 2 are arranged in a central symmetrical manner.
[0010] As an improvement, the hinged part 1 and the hinged part 2 are self-hinged, and the hinged part 1 and the hinged part 2 are each provided with two groups.
[0011] The beneficial effects achieved by the utility model using the above structure are as follows: This solution proposes a tunnel two-way opening fire door, which can achieve the effect of rapid opening in response to fire situations on different sides through a two-way opening method, and the purpose of rapid escape can be achieved regardless of which side of the fire is.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0017] like Figure 1-3 As shown, the utility model proposes a tunnel two-way opening fire door, including a tunnel installation door frame 1, the middle of the tunnel installation door frame 1 is wrapped with a double-sided opening protective door assembly 2, and two groups of symmetrical wall embedding grooves 3 are vertically installed on both sides of the tunnel installation door frame 1, and the two groups of wall embedding grooves 3 clamp the tunnel installation door frame 1.
[0018] like Figure 1 、 2 As shown, the double-sided opening protective door assembly 2 includes a hinge 1 4, a fire door 1 5, a baffle 1 6, a hinge 2 7, a fire door 2 8 and a baffle 2 9. The hinge 1 4 is provided on the tunnel installation door frame 1, the fire door 1 5 is connected to the hinge 1 4, and the baffle 1 6 extends from the side of the fire door 1 5 away from the hinge 1 4;
[0019] The hinge part 27 is arranged on the other side of the tunnel installation door frame 1, the hinge part 14 and the hinge part 27 are arranged in a central symmetrical manner, the hinge part 14 and the hinge part 27 are self-hinged, and the hinge part 14 and the hinge part 27 are each provided with two groups. The fire door 28 is fixed to the hinge part 27, and the baffle 29 extends from the other side of the fire door 28. The baffle 16 and the baffle 29 are symmetrical, and the baffle 16 and the baffle 29 jointly block the gap between the fire door 15 and the fire door 28.
[0020] During specific use, the tunnel door frame 1 is installed to the position of the tunnel entrance. At this time, the two sets of wall engaging grooves 3 are engaged with the wall of the side wall of the tunnel entrance to complete the anti-falling installation and fixation. In case of fire, the fire door 1 5 or the fire door 2 8 can be pushed open to open it on one side to achieve escape, and the hinge 1 4 and the hinge 2 7 are symmetrical about the center, so that the hinged opening directions of the fire door 1 5 and the fire door 2 8 are opposite. The cooperation of the two can achieve the purpose of two-way opening, and the purpose of rapid escape can be achieved when a fire occurs in different directions in the tunnel.
