Abstract

The utility model relates to a visual window fire-proof device for a building. A window frame is arranged on a fire-proof door or a fire-proof wall, and the front side and the rear side of the window frame are provided with fire-proof glass. The interior of the fire-proof door or the fire-proof wall above the window frame is provided with two U-shaped inner frames, and a fire-proof plate is arranged between the two inner frames. The fire-proof plate is supported by a support body which is easy to melt, and both ends of the support body are fixed on the fire-proof door or the fire-proof wall respectively. A stop block is arranged below the support body. When a fire occurs, the support body is melted by the high temperature in the fire site, and the fire-proof plate can fall on a groove of the stop block and obstructs the fire behavior. The utility model has the advantages that a fire source can be obstructed, and the fire behavior can be prevented from spreading and expanding.

Description

Be used for the form firebreak device on the building

The utility model is the form firebreak device that is used on the building about a kind of.The main purpose of labeled door or fire wall or fire prevention shutter door is to block burning things which may cause a fire disaster when breaking out of fire, for the structure of labeled door of commonly using for general traditional type or fire wall 60 or fire prevention shutter door 70 (as shown in Fig. 9, Figure 10), if will on labeled door or fire wall 60, flame resistant glass 61 be set, can be or on fire prevention shutter door 70, be provided with for the louvre blade 71 that ventilates, then above-mentioned being configured in have when using as after shortcoming remain to be improved:

When breaking out of fire, flame resistant glass 61 tends to destroy because of the high temperature in the scene of a fire, and burning things which may cause a fire disaster is invaded by fenestra that ventilates or fire prevention shutter door 70, cause spreading and expansion of the intensity of a fire, though flame resistant glass 61 is is constantly researched and developed in recent years, but reach good flameproof effect, then need reach by thickness and high-tech synthetic materials, this just need expend the higher cost expense.

Shutter door is the usefulness of ventilation or heat radiation, except general bath lavatory, the most important thing is to places such as public place, office, public works underground pipeline, machine room provide required ventilation and heat function, but the fire prevention shutter door 70 of these primary locations can't block burning things which may cause a fire disaster when breaking out of fire.
