Description

Fire retardant heat blocking smoke door door structure

The invention relates to a fireproof and heat-resistant smoke-curtain door panel structure, in particular to a shutter door structure for preventing heat transfer and enhancing smoke from being fireproof, heat-blocking and smoke-blocking.

According to, in daily life, the occurrence of disasters often brings countless loss of life and property to human beings. As far as the fire is concerned, it not only causes a major loss in property, but also a person’s casualties, which is even more irreparable.

Buildings in Taiwan (such as garages, buildings, or homes in buildings) will most likely be in their fire-fighting isolation areas (especially the isolated areas used to isolate the fire source to prevent the fire from spreading further). Iron shutters are installed around, or at the entrance and exit. In the event of a fire accident, in order to effectively control the spread of the fire, prevent it from spreading beyond the fire isolation zone, and strive for more escape time for the trapped people, the iron gate must usually be able to provide adequate fire resistance. ability.

Generally, the structure and components of the conventional fireproof rolling door are blade type and are formed by a single steel sheet. Therefore, when one side is heated, the heat is directly transmitted to the other side without any resistance to heat; or The hot blade is made of two-layer steel sheet, and the interlayer is filled with a heat-resistant layer material such as foamed polyurethane or heat-resistant glass fiber cotton, but the upper and lower blades are hooked to each other at the hook body. Unobstructed heat Therefore, the heat will be directly transferred from the hook to the non-fired surface; thus, it can be seen that the above two conventional blades cannot meet the heat resistance requirements.

Today, the inventor has long been rich in design, development and practical production experience of the relevant industry, and provides a fire-resistant heat-blocking smoke-curtain door structure to achieve better practical value.

The main object of the present invention is to provide a door structure for a fireproof and heat-resistant smoke-proof roll door, and more particularly to a roll door structure for preventing heat transfer and enhancing smoke from fire, heat and smoke.

The main purpose and effect of the structure of the fireproof and heat-resistant smoke-proof door panel of the present invention are achieved by the following specific technical means: the roll door is mainly formed by a plurality of door hooks, wherein the door piece comprises two combined with each other. The first and second sheets are provided with a space for accommodating the heat-resisting layer inside the two-piece body, and the upper end of the door piece is respectively provided with an upper hook portion and a lower hook portion, and is disposed below the lower hook portion The utility model has a groove for accommodating the airtight gasket for blocking smoke; thereby, when a plurality of door pieces are assembled, the hooks can be set to each other, and when the roll door is lowered, the force of the reverse action of the positioning can be made. The upper and lower hooks of the mutual hook chain form a non-contact chain, and at the same time, the airtight cushion is tightly sealed, thereby achieving effective fire prevention measures such as resistance to smoke and resistance to heat conduction.

A preferred embodiment of the light-guided and heat-insulated roof of the present invention, wherein the heat-resistant layer is made of a foam material having high heat resistance, low thermal conductivity and high porosity, such as aluminum base, chromium base, tin oxide or high. Oxygen colloid.

A preferred embodiment of the light-guided and heat-insulated roof of the present invention, wherein a recessed portion is disposed on the top surface of the door piece corresponding to the convex portion, and the recessed portion is in contact with the convex portion. The state is mainly designed such that the recessed portion and the convex portion are separated from each other by a certain distance to prevent heat (temperature) from being transmitted and to achieve a heat-blocking effect.
