Description

Fire-proof device for building facade

Technical Field

The invention relates to the technical field of flame-proof devices, in particular to a flame-proof device for a building facade.

Background

Architectonics, in its broadest sense, is a discipline that studies buildings and their environment. Architecture is a subject spanning both engineering and human arts. Architectural arts and construction techniques involved in architecture, and aesthetic and practical aspects included as architectural arts of practical arts, are clearly different but closely related, and their components are greatly different depending on the specific situation and the building. The building of China is mainly of a wood structure, and the traditional building of the west is mainly of a masonry structure. Modern buildings are mainly made of reinforced concrete. By major facade is meant a facade from which a building is visible from a major viewing angle. The main wall surface of the point type building is a main vertical surface, and the building vertical surface is divided into a building outer vertical surface and a building inner vertical surface. The building interior facade is a general term for the part of all building entities, except the building exterior facade, which is in contact with the exterior space. Generally, references to the facade of a building include all the exterior cladding portions of the building except the roof. In some specific cases, for example, a building roof with a specific geometric shape and a wall body show strong continuity and are difficult to distinguish, or when the roof is treated as a 'fifth facade' of the building for the specific observation angle of the building, the roof can also be made as a component of the facade of the building, which is an important mark for the improvement of civilization. Therefore, the history of using fire by human beings and the history of fighting against fire are concomitant, people continuously summarize the fire occurrence rule while using fire, and the fire and the harm to human beings are reduced as much as possible. In case of fire, people need to escape safely and quickly.

Wall paper can be pasted on the wall usually in modern family and be used for pleasing to the eye, but when the conflagration breaing out at home, the wall paper burning can increase the intensity of a fire, and also has the damage to the wall, causes bigger loss of property, and current fire fighting measure is only to carrying out the fire fighting to the scene of a fire, lacks the special fire prevention device to the wall.
