Structure for reducing friction damage of fireproof and smoke-proof rolling curtain

The present invention relates to a structure which can reduce the friction damage of the fireproof smoke-proof screen, especially a structure which can reduce the friction coefficient between the fireproof smoke-proof screen and the door rail, thereby reducing the friction damage of the fireproof smoke-proof screen and ensuring the fire barrier. The smoke curtain can play a role in preventing the spread of fire and smoke.

Due to the fire, the thick smoke in the fire will be turbulent through various pipes, causing serious damage to people and property. Therefore, the government building regulations will standardize various fire-fighting facilities in the buildings, so large buildings will be planned. Multiple fire zones, with the barrier of fire and smoke insulation devices in each fire zone, can effectively block the spread of fire in the event of fire, to ensure that the fire field no longer spreads; at the same time, in order to consider the usual moving line And the use of the activity space, a large number of fire-proof smoke-proof curtains with fire-proof function, the benefits of it can be hidden, can not hide the use of space, and can be lowered in an emergency to prevent the spread of fire However, in the midst of the deficiencies, the door rails of the fire-proof cigarette screen are generally bent from a metal plate body, and the end of the side wall of the door rail channel on the side of the fire-proof cigarette screen is contained, because of the metal material, plus Its thickness is not very thick, so that its edge is sharp even if it has been edging; because of the fire, the fire-proof smoke After the curtain down, the hot gas stream flows will continue to impact the cigarette fire barrier curtain, so that its end-side side wall of the door rail and channel, is generated Uninterrupted friction, as described above, because the edge of the end of the side wall is sharp, the friction of the contact point is like cutting, and the force of the heat flow is stronger. After a long time, the fireproof smoke-proof curtain is easy to be from the side and the door rail. The contact points at the end of the side wall cause damage and gaps, which in turn results in a significant reduction in the effect of fire and smoke.

In view of this, after many times of research and improvement, the creator of this case finally completed the structure of the case that can reduce the friction and damage of the fireproof and smoke-proof curtain, that is, the purpose of the present invention is to provide a kind of friction between the fireproof smoke-proof curtain and the door rail. The structure of the coefficient is used to reduce the friction damage of the fire-proof smoke-proof curtain, and to ensure that the fire-proof smoke-proof curtain can exert the effect of preventing the fire and the spread of smoke.

In order to achieve the above-mentioned purpose of the present invention, the present invention can reduce the structure of the friction and damage of the fire-proof and smoke-proof screen, and comprises a two-door rail and a fire-proof cigarette screen, wherein: the door rail has a guiding port on one side thereof, the guide The lead port is composed of two side walls of the door rail extending inwardly of the plate body, and the side wall is disposed obliquely, so that the front end opening width of the guide port is wider, and the end opening width is narrower, and the two side walls are respectively Extending a skid plate, and forming a sliding passage between the two slip plates for passing the side of the fireproof smoke-free roll screen; the fireproof smoke-proof roll screen is composed of a fireproof material cloth body, The fireproof cigarette screen is disposed on both sides of the door rail.

The above-mentioned slip plate is a Teflon plate body.

The above-mentioned slip plate is a fireproof board body.

The above-mentioned slip plate is a metal plate body.

The end face of the above-mentioned slip plate contacting the fireproof smoke-proof curtain is a smooth surface.

The above-mentioned fireproof cigarette screen has at least one side flap on both sides thereof, the end of the side flap is connected to the fireproof cigarette screen, and the other end of the side panel extends obliquely outward from the end, the The inner side of the side panel abuts against the outside of the slip plate.

The side walls of the guide port on the two sides are arranged in an oblique direction.

The above-mentioned slip plate and the fixing of the side wall are fixed by a fixing component.

The fixing element described above is a rivet and a screw.

Please refer to the first, second and third figures. The structure of the present invention can reduce the friction damage of the fire-proof and smoke-proof screen, and comprises a two-door rail 1 and a fire-proof smoke-winding curtain 2, wherein: the door rail 1 has one side There is a guiding port 10, the guiding port 10 is composed of two side walls 11 of the door rail 1 extending inwardly of the plate body, the two side walls 11 each extending a slip plate 3, and the two sliding plates are A sliding passage A is formed between the three to pass through the side 20 of the fireproof cigarette screen 2; the fireproof smoke curtain 2 is composed of a cloth body of fireproof material, and the two sides of the fireproof smoke screen 2 It is disposed in the door rail 1.

The above-mentioned slip plate 3 is fixed to the side wall 11 and is fixed by a fixing member 4, and the fixing member 4 is a rivet and a screw.

The above-mentioned slip plate 3 is a Teflon plate body.

The above-mentioned slip plate 3 is a fireproof board body.

The slip plate 3 described above is a metal plate body.

The above-mentioned slip plate 3 has an end surface 31 which is in contact with the fireproof smoke screen 2, and has a smooth surface.

In the above-mentioned guide port 10, the side walls 11 on both sides are disposed in an oblique direction, so that the front end opening width of the guide opening 10 is wider, and the end opening width is narrower.

The fireproof cigarette screen 2 is provided with at least one side flap 21 on both sides 20, and the end portion 22 of the side flap 21 is connected to the fireproof cigarette screen 2, and the other end of the side panel 21 is from the end 22 extends obliquely outwardly, and the inner side of the side panel 21 abuts against the outside of the sliding plate 3, so that a cross-shaped arrangement is formed between the fireproof cigarette screen 2 and the side panel 21, thereby sealing the door rail 1 sliding passage A, which provides a fire alarm when the fireproof smoke screen 2 is lowered, and a side of the fireproof cigarette screen 2 can be sealed between the fireproof smoke screen 2 and the sliding passage A when pressed against the hot air flow The gap prevents the hot air from colliding, thus preventing the spread of fire and smoke.

As shown in the fourth figure, the present invention can reduce the structure of the friction and damage of the fireproof smoke-proof screen. With the composition of the above components, when the fire-proof smoke curtain 2 is put down, the hot air flow pulls the fire barrier. In the case of the cigarette screen 2, since the sliding plate 3 has a smooth surface with the end surface 31 of the fireproof smoke-curtain 2, the friction coefficient of the contact surface is low, so that the sliding surface of the smoke-proof screen can be reduced. The friction damage ensures that the fireproof smoke screen 3 can prevent the fire and the spread of smoke.

In summary, the creation can reduce the structure of the friction and damage of the fireproof and smoke-proof screen, and the structure of the surface friction coefficient of the sliding plate and the fire-proof smoke-proof roll screen is low, thereby reducing The friction between the fire and the smoke-proof screen is low, ensuring that the fire-proof and smoke-proof screen can prevent the fire and the spread of smoke, prevent the chaos of the hot air, and prevent the spread of fire and smoke, effectively solving the problem. The existence of the missing, and the technology used is unprecedented, so this creation is unique to the novelty and progressive requirements of the new patent.
