How to prevent the fire of building exterior insulation materials Jiayan Henan Army Reserve High-altitude Artillery Group II (450100) comprehensively discusses the energy-saving and efficiency improvement of civil building external thermal insulation system, which is also one of the causes of frequent fire accidents. It is extremely urgent to do a good job in fire prevention of building exterior insulation materials. Briefly discuss the relationship between modern building exterior insulation materials and fire safety, and analyze the building exterior insulation materials.
1 Types of building thermal insulation materials From the point of view of material burning, the current application of building exterior insulation materials mainly includes the following three categories: inorganic insulation materials. Including rock wool, glass wool, expanded vitrified microbead insulation slurry. It is a non-combustible material (Grade A) and does not have fire safety problems. However, in the process of processing, organic binders or additives are sometimes added, and the addition of these substances may have a certain influence on the combustion performance of the product.
Organic and inorganic composite insulation materials. It is mainly composed of rubber powder polystyrene granule insulation slurry, which is a flame retardant material (B1), and has no flame propagation property, and its own fire safety problem is small.
Organic polymer insulation material. It is mainly composed of polystyrene foam and is a flammable and combustible material, posing a fire hazard.
Analysis of fire accidents caused by frequent external thermal insulation materials in recent years, its occurrence is divided into four stages: 1 preparation for construction, construction of insulation materials at the construction site; 2 construction process, insulation materials on the wall construction stage; 3 construction ends, outside The insulation system is put into use; 4 the external insulation system is reconstructed during the construction process. In these four stages, no matter which stage of the fire occurs, it will cause different degrees of loss.
2 Comprehensive prevention of fire accidents of building exterior insulation materials Building fire accidents occurred throughout the country. If the design, construction and use of external insulation materials are unreasonable, it will bring huge fire safety risks to the buildings. Therefore, it is necessary to comprehensively prevent fire accidents of building exterior insulation materials.
It is necessary to strictly control the fire protection design review (recording) and stick to the defense line of fire accidents of building exterior insulation materials.
The current national fire protection technical specifications, high-rise civil building design, fire code, building design, fire protection specifications, etc., classify the combustion properties of building materials, and stipulate the combustion performance and fire endurance of building components used in different fire-resistant buildings. Obey the above regulations, strictly check the entrance, prevent the construction project from starting with the disease, and prevent the fire hazard of the building exterior wall insulation material from the source.
It is necessary to establish a multi-sector joint supervision mechanism to promptly rectify various fire hazards and fire-fighting violations.
Establishing a mechanism of “source control, sampling and inspection, departmental coordination, and full supervision†is the key to effectively curbing fire accidents in external thermal insulation systems. “Source check, sampling and inspection†means that the selection of external thermal insulation materials is supervised through fire protection design review, review and sampling inspection, and the combustion performance of materials is strictly controlled: “departmental coordination, full supervision†is to coordinate the construction authorities and Its related business units, and fire protection agencies, the external thermal insulation system from the design, materials to the construction process for all-round supervision. Construction work has always been the focus of fire supervision and inspection work. On the basis of special rectification, take practical and effective measures to improve and strengthen fire safety supervision and management. For unexamined buildings, comprehensive investigation should be carried out, and hidden dangers should be eliminated within a time limit. Through strengthening local legislation, formulating local standards, researching and developing new building exterior wall insulation materials, and exploring measures to establish a long-term mechanism to strengthen the supervision of building exterior wall insulation materials.
It is necessary to strictly implement the fire safety responsibility system at the construction site of the construction site and improve the fire prevention capability.
Tissue engineering technology and construction personnel are deeply familiar with the design drawings and are familiar with the fire safety factors that intersect and exist during the construction process. Prepare special construction plans for thermal insulation materials, and formulate technical documents to ensure technical quality measures and safe operation procedures. Prepare special fire safety programs to ensure fire safety in construction. Develop emergency plans based on actual drills to achieve the purpose of enhancing emergency awareness. Implement safety production systems such as fire safety production responsibility system, fire safety inspection system, and pre-class safety activities. In view of the frequent use of fire and electricity at the construction site and the possibility of fire, it is necessary to supervise and guide the construction unit to carry out the “four capabilities†construction of fire safety, strengthen the fire safety education and pre-job training for employees, and enable the construction personnel to achieve “three understandingsâ€. "Requirements to improve self-defense and self-rescue capabilities.
It is necessary to vigorously organize the special training on fire safety and improve the fire safety awareness of construction workers in construction.
Regularly organize construction project manager, construction unit manager, design institute staff, etc. to carry out building exterior wall insulation material fire talk about the interaction between architecture and culture and art. Gaotian Zhengzhou University School of Architecture (450000) comprehensively discusses architecture as human life. An important material basis that is inextricably linked to the social, cultural and artistic forms that humans have formed over thousands of years. Architecture is not only the carrier of social life, culture and art. It also serves as the essence of human thought and practice and embodies the relatively large investment of man-made objects. In many aspects, it also refers to social life, cultural trends and artistic expression. It has a very direct impact. The vast majority of modern human production and life are carried out in man-made buildings and sites. A building may be weak in macro view, but in terms of individuals, it can even be used for family life, streets, communities and even It has a decisive impact on cities and society.
In the art form of film, painting, literature, music, etc., there is no lack of feeling of the existence of architecture. It has a long-term influence on the expression of these art forms, and it is not difficult to see the aesthetic influence from these art in the style of architecture. .
If we associate in the brain with a city we have never been to, the first thing that comes to mind is about the characteristics and things of the city.
It is not difficult to find that among these things that evoke our association with a city, architecture – whether it is a modern landmark or a historical monument – ​​is often the most distinctive representation. For example, when we think of Athens, we will think of the world-famous Acropolis; when we think of Dubai, we will think of the sailing hotel or the Burj Khalifa, and even extend the scope of Lenovo to the country. If you think of France, you will think of the Louvre or Notre Dame. When you think of Egypt, you will think of the pyramid. Perhaps in Lenovo's culturally rich cities and countries, you can think about all aspects of their culture and art, but it is undeniable that the great architecture is the most impressive and the most representative of the culture that gave birth to it.
Why architecture can represent a culture more comprehensively than other artifacts or art and thoughts. The Austrian country is connected with music in the minds of most people, but most people know that her capital is Outside of Vienna, the world's famous music capital, she has almost no special lectures on prevention, and fully utilizes various propaganda methods to raise awareness of fire safety among relevant personnel. Actively plan to carry out fire safety patrol training courses for building exterior insulation materials and firefighting skill competitions for construction workers. In addition to the prestigious art of music and painting, it is difficult to see other qualities of this country from the music. Because music is one of the greatest artistic forms of human beings, it is not a necessity for human existence, and its influence on human beings is not big enough. Although it seems that the art form of architecture, which originated from practicality and later formed artistic logic, is slightly unfair compared with the pure art form of music, especially now, whether architecture can be called art or an important foothold One of the points, it can be said that this duality has derived other characteristics of the building, making the building more prominent.
In addition, the origin of architecture is almost accompanied by the origin of civilization. I would like to ask, besides human beings, what kind of man-made objects can be directly followed and still flourishing development buildings with their ancient history proves that human development is at least not It needs its existence in the distant future. Architecture can be seen as a collection of artifacts. People use their experience and technology to create such a huge structure that makes it strong and practical, making it beautiful. This collection of wisdom makes the building difficult to replace with other man-made objects. Of course, it can be said that the man-made objects with the same purpose as the building can be called buildings. This means that in the future, people are likely to discover other ways of building buildings, which are greatly different from the current structure, perhaps a living building that is directly grown using improved plants, perhaps a new low-density, high-strength material. As a building that breaks the form of gravity, it is even possible that the building is no longer just standing on the ground, but floating in the air or floating in the water; the aesthetics of the building may also change greatly, and the sense of the future is more mechanical. Or a more organic and dynamic sense of biology; perhaps some buildings will give up the most essential functions, and pure pursuit of artistic or emotional. These futuristic artifacts are likely to subvert our current understanding and definition of architecture, but it is as if ancient people could not believe that today's people can make skyscrapers close to a kilometer, and we can't just use the current narrow-mindedness to bind the future. The submarine prefabrication of the building and the knowledge of the fire safety of the construction personnel have been greatly improved to prevent the occurrence of fire accidents.
