Description

{Fire prevention glass automatic door for practicable of semi automatic}

[0001] The present invention relates to an automatic door for an automatic closing of a fireproof glass, and more particularly, to an automatic door for an automatic closing of a fireproof glass, which is a fire door installed in an fire compartment and is interlocked with a fire alarm to shut off commercial power, Automatic door opening / closing control device installed at a predetermined position or an object detecting sensor enabling an automatic door opening is closed automatically when a power source is short-circuited due to a flame and a driving device or battery trouble occurs, It is required to have the function of the structure which is always closed because of the nature of the automatic door of the fireproof glass.

Fireproof glass automatic door is a new function of fire door to protect flames and toxic smoke when fire occurs to protect human life and property. Fire doors are generally made of geared motor, And is connected to a chain or belt that is made to reciprocate and is opened or closed to one side, left side, or right side along the guide rail. At this time, the roller bracket is attached to one or both of the upper end surfaces of the movable door frame of the fireproof glass automatic door to allow the sliding door to move more smoothly in a state in which the movable door is seated on the guide rail, The motor-driven chain gears installed on both sides of the fixed door and the movable door frame, respectively, and the motor-driven chain gears installed on both sides of the fixed door and the movable door frame, respectively. A geared motor for imparting power to the chain or the belt for connecting the driven chain to the belt, a guide rail for allowing the rolling roller to reciprocate in the fixed door and the movable door frame, and a driving chain gear and a driven chain gear And a roller bracket for fixing and supporting the belt As shown in Fig. The automatic door of fireproof glass drives the geared motor by the commercial AC power source and automatically opens and closes by the control device of the geared motor. When the power failure or smoke alarm is activated, it is driven by the power of emergency battery. It consists of a control device for controlling the motor with battery and commercial AC power supply, an access control device for controlling entrance and exit, a sensor for automatically opening the control device by detecting the object, and a door open switch. When a fire occurs, a high temperature caused by a flame causes a short circuit between AC power or an emergency battery or a signal device is short-circuited. In such a case, an emergency battery is broken and the automatic door of the fireproof glass is opened or stopped, Main function of glass automatic door There is a problem that the flame and toxic smoke can not be blocked. On the other hand, when the emergency battery is normally charged by a commercial AC power source, the automatic door of the fireproof glass is driven by the power of the emergency battery when a power failure or a fire alarm is activated. However, It stops the flame and the toxic smoke which is the original function of the automatic door of the fireproof glass, so that the toxic smoke spreads to cause loss of human life and the flame can not be prevented from spreading.

The object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to provide a fire- Which can be opened automatically and closed automatically to prevent the automatic doors of the fireproof glass from being opened when the power supply is cut off due to loss of operation or power supply is lost. Which can be opened manually and automatically closed even when there is no door, even if there is no door.

In order to accomplish the above object, according to the present invention, there is provided an automatic fire door automatic door which is manually opened and closed according to the present invention comprises a power transmission part including a gear motor and a chain connected to a driven chain, A roller rail is provided on a roller bracket for fixing and supporting the upper end of the movable door frame of the glass automatic door, and a guide rail is provided so that the movable door can reciprocate horizontally, and at least one roller roller is provided, When at least one solenoid is fixed to one part of the roller bracket and the geared motor is driven, the chain connected to the driven chain gear fixed to both sides of the door frame is fixed to one part of the roller bracket. The solenoid plunger is inserted into the groove of the segment of the chain and moved horizontally At least one tension device in which the movable door is elastically restored such that the wire is wound or unwound by the movement distance by the horizontal pressure, the wire of the tension device is fixed to the roller bracket, and the roller bracket As shown in Fig. The tensioning device may include at least one adjusting end capable of damping the force of the tension. The wire termination of the tensioning device may further include a mounting portion for fixing to a part of the roller bracket.

According to the automatic door opened automatically and closed by the above-mentioned structure, when the fire occurs, when the sensor, the access control device and the emergency battery installed in the predetermined position of the fireproof glass automatic door occur, the door is closed It is possible to prevent the transition of the flame by closing the moving door due to the elastic restoring force of the tension mechanism even when it is stopped in the middle of opening and to protect the life and property by blocking the toxic smoke and to compensate for the deadly shortcomings of the existing installed fire- to provide.
