Fire proofing rolling door

Abstract

The invention relates to a water-proof flexible gate, which comprises a box body, a metal flexible gate and a guide rail, wherein a scroll bar, a winding engine and a hand-operated chain are arranged in the box body, the metal flexible gate is constituted by a plurality of blades which are mutually hitched. The invention is characterized in that the upper ends and the lower ends of the blades areprovided with hook braking bodies after the blades are shaped, the front side and the rear side of the upper hook braking bodies are integrally extended with retaining walls with preset heights, an upper blade and a lower blade are mutually hooked to take a joint, which are hidden the front retaining wall interlayer and the rear retaining wall layer of the blade, the surfaces of a pair of retaining walls and the upper hook braking bodies are all coated with fire-proof material, and the blades are provided with a front interlayer and a rear interlayer to form hollow status, and the left and the right lateral sides of the blades are sealed. The water-proof flexible gate can lead a metal roller door to have fire-proof effect, which improves safety performance.

Description

technical field [0001] The invention relates to a fireproof rolling door, in particular to a safe metal rolling door which has an excellent heat-resistance effect and can be fireproof and heat-resistant. Background technique [0002] The occurrence of fire not only causes heavy losses in property, but also causes irreparable regrets if there are casualties. Due to the rapid economic growth of Taiwan, China, a large population is concentrated in cities. In order to meet the housing needs of high-density population, public and residential buildings are all developed in the sky, resulting in high-rise buildings standing tall in the city. Although these majestic modern buildings bring more comfortable life enjoyment, once a fire occurs, the loss will be very serious and tragic. Therefore, how to take into account fire safety in modern architectural planning is a concern of the government and the industry. The government must cooperate to formulate timely regulations, and the in...

Problems solved by technology

However, the blade 50 of the rolling door at the bottom is made of stainless steel or galvanized and painted steel, so it is not easy to be designed as heat-resistant; please refer to Figures 2 and 3, where Figure 2 shows the traditional blade 501 , is formed by a single steel sheet, so when one side is heated, the heat will be directly transferred to the other side without any heat-resistant effect; Figure 3 shows a double-layer heat-resistant blade 502, which is made of double-layer heat-resistant blades. It is made of pressed steel sheets, and the interlayer is filled with heat-resistant materials 503 such as foamed polyurethane or heat-resistant glass fiber cotton. However, there is no heat-resistant design at the hook body where the upper and lower blades are connected to each other, so The heat will still be directly conducted from the hook to the non-fired surface; it can be seen that the above two existing blades cannot meet the requirements of heat resistance performance

[0006] In addition, as far as the guide rails of the fireproof rolling door are concerned, please refer to FIG. 4 . In order to prevent theft and strengthen the structural strength of general rolling doors, the guide rails 60 are buried inside the building structure, and the two ends of the blades 50 are deeply embedded. In the guide rail 60, to disassemble and separate the blade 50 from the guide rail 60, it must be done by professionals using special tools, and ordinary people can disassemble it by themselves

Moreover, because the power supply of the building will be cut off when a fire occurs, the rolling door cannot be opened once the power is cut off. Moreover, when a fire occurs, there is not enough time to disassemble the blades and guide rails. At this time, the fireproof rolling door not only hinders One of the main reasons for causing heavy casualties

[0007] It can be seen from the above description that up to now, there is no fire safety rolling door product with good heat resistance and anti-theft performance on the market.
