What problems will be encountered when fireproof glass is used

Hello everyone, I'm Xiaobian. Today, I will introduce to you the problems encountered in the use of fireproof glass. The following content is organized by the editor, and the relevant content is for reference.

1. Normally closed fireproof glass windows: In addition to the necessary fireproof performance, normally closed fireproof glass windows also need the function of active closing and sequential closing. When installing fireproof glass windows, the verticality of the front, rear, left and right sides must be horizontal. Level the ruler or correct it with the hanging line method to achieve horizontal, vertical and equal heights. These supporting functions cannot be ignored, otherwise many hidden dangers will be left. At present, most of the fireproof glass windows are used in our country, mainly because the components used are simple mechanical products, the manufacturing equipment is simple, and the cost is low. But normally closed fireproof glass windows have many disadvantages:

(1) Fireproof glass windows are scattered in aisles, stairs and front halls. Fireproof glass windows are often closed, which brings unnecessary trouble to normal traffic. Many places are open for easy access.

(2) Because this place is usually a place where people often walk, the traffic is heavy, and the door is often open, it is inevitable that the fireproof glass window and its hardware will be damaged frequently, especially the door closer. Once the viewing angle when the device is turned on is larger than the viewing range, the active shutdown function cannot be used.

(3) When the engineering inspection is put into use, the door closer is usually debugged to close the door. However, in the event of a fire, the impact force of the hot air expansion will create a certain pressure difference on both sides of the fireproof glass window. Adjusting the door closer makes it difficult to secure fire glass windows. In this way, fireworks will enter the public hall, firefighters will not be able to enter the hall to save lives, it will become unsafe to use closed stairs to escape, etc.

2. Normally open fireproof glass windows: In the specification, three "should" words are used in a row for normally open fireproof glass windows, and it is strictly emphasized to increase the signal response function on normally closed fireproof glass windows. In addition, these three basic skills must be possessed, among which One is essential. Most fireproof glass windows on the market today have the functions of "self-sealing" and "signal response", and the functions are short and reliable. Many fire cases have confirmed this. Since the fireproof glass windows cannot be safely closed, the fire spreading on the site cannot be effectively isolated.
