the left side position of the fireproof door is parallelly provided with a positioning door bolt, the positioning door bolt is rotatably connected to the fireproof door, a positioning door nose is arranged on the door frame wall on the right side of the fireproof door, and the positioning door bolt is horizontally rotated to the positioning door nose to be fixed;
control switch is installed to right side door frame wall below, prevents that the fire door upper right corner installs the magnetic lock steel sheet, and the magnetic lock tapered end is installed on the door frame of magnetic lock steel sheet top, control switch is connected with the magnetic lock tapered end through the contact passageway circuit that sets up in the door frame wall, the magnetic lock tapered end is connected with the magnetic lock steel sheet after the circular telegram.
Furthermore, the positioning door nose is L-shaped and is vertically fixed in the door frame wall.
Furthermore, the limiting door shaft is L-shaped, and the length of the limiting door shaft is greater than that of the limiting steel shaft.
Further, the magnetic lock head is connected with a track traffic control center.
The invention has the beneficial effects that:
according to the invention, the steel plate is embedded vertically on one side of the doorframe wall, the butterfly-shaped positioner and the limiting steel shaft are arranged on the steel plate, the limiting steel shaft is inserted into the limiting steel shaft, one end of the limiting steel shaft is fixedly connected with the fireproof door, and the other end of the limiting steel shaft is fixed through the sealing pin, so that the fireproof door is firmly installed and fixed; meanwhile, a magnetic lock head and a magnetic lock steel plate are installed on the upper right side of the fireproof door, the magnetic lock head is connected with a control switch or a rail traffic control center through a communication channel circuit, when the control system is not powered off or is not in a fire disaster, a positioning door bolt and a positioning door nose on the fireproof door are used for closing the fireproof door, and the control switch or the rail traffic control center arranged on the door frame wall is used for controlling power on, so that the magnetic lock is powered on to generate huge attraction to lock the fireproof door, the fireproof door is prevented from shaking along with piston wind, and the fireproof door is firmly sealed.
And, when through control system or meet with the conflagration and lead to the silicon steel plate outage back, magnetic force disappears, prevents that fire door directly opens through the location keeper, has made things convenient for personnel in the interval to pass through.

Detailed Description
The invention is further illustrated with reference to the following figures and examples.
As shown in fig. 1 and 2, the wind pressure resistance and settlement resistance fireproof door for the contact channel of the rail transit section comprises a fireproof door, a steel plate 101 is embedded inside a left frame wall 11 of a fireproof door 12 in an up-down symmetrical mode, two butterfly-shaped locators 102 are symmetrically welded on the steel plate 101, and a round hole is formed in the center of each butterfly-shaped locator 102.
In addition, a limiting steel shaft 103 is inserted into a round hole formed in the butterfly positioner 102, the limiting steel shaft 103 is in full-welding connection with the butterfly positioner 102, a limiting door shaft 104 is inserted into the limiting steel shaft 103, one end of the limiting door shaft 104 is welded with the fireproof door 12, and a sealing pin 105 is installed at the other end of the limiting door shaft 104.
Meanwhile, a positioning door bolt 108 is installed on the left side of the fireproof door 12 in parallel, the positioning door bolt 108 is connected to the fireproof door 12 in a rotating mode, a positioning door nose 109 is installed on the doorframe wall 11 on the right side of the fireproof door 12, and the positioning door bolt 108 rotates horizontally to the positioning door nose 109 to be fixed in the door.
Prevent that fire door 12's right side door frame wall 11 below installs control switch 13, prevent that fire door 12 upper right corner installs magnetic lock steel sheet 106, magnetic lock tapered end 107 installs on the door frame of magnetic lock steel sheet 106 top, control switch 13 is connected with magnetic lock tapered end 107 through the contact channel circuit that sets up in door frame wall 11, magnetic lock tapered end 107 circular telegram back is connected with magnetic lock steel sheet 106.
The positioning nose 109 arranged on the fireproof door 12 is L-shaped and is vertically fixed in the doorframe wall 11. And the limiting door shaft 104 is L-shaped, and the length of the limiting door shaft 104 is greater than that of the limiting steel shaft 103.
Meanwhile, the magnetic lock head 107 can also be connected with a rail transit control center.
Example 1
When a fire disaster does not happen in a subway tunnel, during the operation of the subway, the fireproof door does not continuously bear the large positive and negative pressure of piston wind in the tunnel, at the moment, the fireproof door 12 of the connection channel is welded with one end of the limit door shaft 104, the steel plate 101 embedded in the door frame wall 11, the butterfly-shaped positioner 102 fixedly arranged on the steel plate 101 and the limit steel shaft 103 firmly fix the limit door shaft 104, so that the fireproof door 12 is more stable than the hinge connection, the positioning door bolt 108 on the fireproof door 12 is fixed with the positioning door nose 109 to close the fireproof door, but the fireproof door 12 is fixed only through the positioning door bolt 108 and can swing along with the piston wind, therefore, the magnetic lock head 107 arranged on the door frame is connected with the control switch 13 or the rail traffic control center through the connection channel circuit arranged in the door frame wall 11, the control switch 13 or the rail traffic control center is connected with the control power supply, so that the magnetic lock head 107 is, the magnetic lock steel plate 106 arranged at the upper right corner of the fireproof door 12 is firmly sucked, so that the fireproof door 12 is firmly closed, the fireproof door is stably connected and does not shake along with the piston wind.
Example 2
On embodiment 1's basis, when subway tunnel conflagration breaks out, cause the outage of track traffic control center or through pressing control switch 13 outage for magnetic lock tapered end 107 cuts off the power supply, thereby no magnetic force attracts magnetic lock steel sheet 106, prevents that the location keeper 108 on the door 12 falls down from location door nose 109 this moment, prevents that the door opens, and the personnel in the convenient contact interval pass through.
Prevent fire door and adopt the hinge to fix on the door frame usually among the prior art, stability is relatively poor. Under the long-term action of piston wind, the fireproof door is easy to deform and even fall off, and serious potential safety hazards exist.
