The present invention relates to a fire door, and more particularly, by improving the conventional method in which opening and closing more than a set angle is impossible due to structural limitations, a rotational movement extended to a range of 180° by electronic control is implemented more easily and accurately, thereby actively improving convenience. In addition, the ease of handling, use, maintenance, maintenance, and repair resulting from a differentiated structure compared to the previous one maximizes the convenience of operation and efficiency in use.In addition, the door and the door frame are completely shielded in case of a fire, so that it is proactive from the risk of fire. It relates to a 180° open fire door that can be completely sealed in case of a fire that can participate in the protection of human life.

In general, fire doors are structures such as entrance doors or emergency doors that are installed to block the spread of fire to the back side of houses, apartments, factories, offices, and prefabricated temporary buildings, and this is a square-shaped door frame that is first installed through the wall. And, in a state sandwiched between the door frames, one side includes a door that is coupled to the door frame with one or more pivoting means (hinge, pivot hinge), and a handle is usually installed on one side of the door to open and close the fire door.

Fire doors as described above are made of metal such as steel plate to prevent flame from spreading in the event of a fire, but these fire doors are completely airtight and sealed, such as a gap or gap between the door and the door frame in long-term use. It is structurally difficult, and because of this, flames flow into or out of the room, causing injury and death due to burns.

In addition, since air inflow or outflow occurs through gaps or gaps formed in the door and the door frame, significant energy loss occurs during cooling and heating, and noise generated from the interior and exterior is transmitted to the opposite side of the fire door without filtering. Cause.

Therefore, in order to seal the space formed on the door of the fire door and the door frame, the sealing packing or the sealing protruding piece was adhered using adhesives and adhesive tape, or installed with bolts or screws. As such, the fire door using adhesive and adhesive tape In the case of attaching the sealing packing to the sealant, it is not easy to change the position after bonding. If the position is unavoidably changed, the sealing packing must be removed from the fire door and then re-attached. As a result, there is a problem in that adhesion is lost and easily separated at the same time.

In addition, in order to mount the sealing protrusion to the fire door, it is not only inconvenient to fasten the bolts, but when changing due to the user's incorrect position selection, the inconvenience of disengaging the fastened bolts and then tightening them again. there was.

On the other hand, a method of attaching a fire sheet to the inner side of the door frame where the fire door is to block flame or air, which are the main functions of the fire door, and a fire protection band, which is one of the fire protection materials, is attached around the edge of the door of the fire door facing it. have.

In particular, the above-described fire band is a method of blocking the outflow and inflow of smoke and toxic gases, especially when heat is transmitted to the door or door frame of the fire door by flame, causing the fire band to undergo chemical changes and foaming in the gap between the door door and the door frame. to be.

However, in this type of fire door, since the fire door is simply attached to the inside of the door or the door frame, it is damaged when the fire door is frequently opened or closed, or it is pressed in exposed state, thereby damaging the appearance of the fire door, and dust or foreign matter. There were many difficulties in management, such as maintaining a dirty state by the back.

Above all, the present invention improves the conventional method in which opening and closing more than the set angle is impossible due to structural limitations, so that the rotational movement extended to the 180° range by electronic control is implemented more easily and accurately, thereby actively improving convenience and differentiated Due to the ease of handling, use, maintenance, maintenance, and maintenance resulting from the structure, the convenience of operation and efficiency in use are maximized, and in case of fire, the door and the door frame are completely shielded so that it can participate in active protection from the risk of fire. Note that it relates to a 180° open fire door that can be completely sealed in case of fire.

As shown in Figs. 1 to 8, the functional fire door proposed as a feature of the present invention is provided in a 180° front open type with a more simplified and differentiated structure by improving a conventional method that could not open or close more than a certain angle.

In particular, the present invention is a main part to provide a 180° front open fire door with a predetermined structure for completely blocking the gap between the door panel 40 and the door frames 20, 30, and will be described in detail below. do.

The functional fire door of the present invention is largely composed of the wall 10, the first and second door frames 20 and 30, and the door panel 40, and various locking means including sensors capable of electronic control according to convenience and embodiments This may include more.

Preferably, a wall 10 of a known structure, a first door frame 20 and a second door frame 30 disposed spaced apart from each other at positions corresponding to each other through the wall, and a rotating shaft 41 formed of a non-combustible material It includes a door panel 40 that is determined whether to open or close while turning from the second door frame by the.

At this time, the door panel 40 described above should be configured to completely block the gap between the first door frame and the second door frame as the rotation movement by 180° is allowed due to the setting signal when a fire is detected in a state in close contact with the wall. do.

More preferably, in the construction of the second door frame 30 above, the detection unit 31 and the a-shaped are arranged vertically on the same line as the wall 10, and detect heat or smoke in real time and transmit it to the control unit 50 A bending frame 35 for constructing the receiving hole 32 should be further configured.

The sensing unit 31 refers to a conventional sensor, and transmits changes in conditions such as internal temperature, heat, and smoke obtained from the sensor to the real-time controller 50 to induce a more urgent response to an unexpected situation. In addition, such a control unit 50 enables electronic control by interlocking with a predetermined operation unit 11 that controls the opening and closing of the door panel 40, and in case of emergency based on various information obtained from the sensing unit, the door panel In order to determine whether to open or close the door panel, an operation unit that can be operated in a manner such as an electromagnet is integrally formed on the door panel.

That is, the upper wall 10 is further configured with an operation unit 11 that executes opening and closing of the door panel 40 when a fire is detected while the operation is determined by receiving information due to the detection unit 31 from the control unit 50 do.

In addition, the upper door panel 40 is a mounting portion 45 that shields the inner space of the receiving hole 32 by overlapping with the acting portion 42 corresponding to the operation portion and the bending frame 35 formed curved on the second door frame end. Is further composed.

The working part 42 and the operation part 11 are kept constrained to each other by magnetism or other means, and when an emergency situation such as a fire occurs, the operation part is arbitrarily controlled through the control unit, thereby separating or disengaging from the working part. Is implemented.

On the other hand, the present invention reflects the technical idea for completely blocking the gap between the door panel and the door frame, as is well known. This is the bending frame 35 of the second door frame and the mounting portion 45 of the door panel described above. It is done more completely by means.

As shown in detail in FIG. 3, the bending frame 35 is formed to be bent in a shape of a C at any end of the second door frame 30, and at this time, the internal space of the second door frame is naturally a receiving hole 32 having an a shape. While this is provided, it is possible to allow the entry of all components when the door panel rotates.

The upper mounting portion 45 is formed in a shape corresponding to the bending frame, and is positioned in a state of being overlapped with the bending frame 35 due to the door panel 40 that is rotated from the rotation shaft 41 as a starting point, thereby contributing to strengthening the sealing force. This configuration is the main core issue of the present invention, and the related structure of the mounting portion and the bending frame is not exposed to the outside even in the open state of the door panel, so that it is possible to achieve a clean and beautiful visual beauty, and close contact with each other even when the door is closed. Due to its structural characteristics, it is more completely sealed without any additional means.

On the other hand, when a fire occurs, the air pressure in the fire-producing space rises, and the corresponding air pressure induces a strong stress in the bonding area between the bending frame 35 and the mounting part 45, causing structural deformation or damage in severe cases and spreading the fire. have.

Therefore, in order to prepare for the above situation, a U-shaped reinforcing piece (not shown) is attached to the inner surfaces of the bending frame 35 and the mounting part 45, respectively, to improve the durability of the bending frame and the mounting part itself. In addition, it was constructed so that the cohesion between each other became stronger.

The first door frame 20 is made of a non-combustible material that protrudes to support when interfering with one surface of the door panel 40 and wraps the outer surface of the ground part to reduce the amount of impact caused by the door panel or strengthen the sealing force. The elastic pad 22 is further configured.

As shown in the drawing, the ground part 21 is a configuration for contributing to the reinforcement of airtightness in a predetermined area of the first door frame 20 bent in multiple stages when the door panel 40 is closed. Prevent smoke, etc. from being discharged to the outside.

The elastic pad 22 must be formed of various known non-flammable materials, and has a tension or cushion sufficient to absorb some of the impact caused by the door panel.

In addition, the door panel 40 of the present invention may further include an extension 46 at an end portion for completely blocking a gap between the first door frame 20 and the overlapping portion.

As shown in the drawing, the extension part 46 covers the bent area of the first door frame 20 and induces the airtightness to be further strengthened, and it is sufficient if it extends in the horizontal direction from one end of the door panel 40. However, it is a self-evident fact that durability must be secured so that it is not easily bent or damaged by external impact.

According to the present invention made of the above-described configuration, the gap between the door panel and the door frame is completely sealed by a structural characteristic in which the predetermined bending frame 35 and the mounting portion 45 are overlapped with each other in multiple stages to prevent flame and smoke in case of fire. And there is an effect of blocking the inflow or outflow of toxic gas, etc. indoors or outdoors.

Accordingly, the present invention not only can more efficiently prevent human damage such as burns, suffocation, and death, but also completely blocks dust, noise, and light, and at the same time increases the insulation effect to further improve the indoor residential environment. The advantage is also expected.

In addition, the present invention provides an effect of maximizing the convenience of operation and efficiency in use by providing a 180° front open fire door with a more simplified and differentiated structure unlike the existing one, and includes a separate element such as a conventional fire band. There is an effect that can make simple construction and aesthetics beautiful because it is not done.
