Description

Technical Field

[0001] The utility model relates to the technical field of steel plate walls, and particularly to a steel plate wall with fire and heat insulation functions. Background Art

[0002] Industrial plants such as nuclear power plants and chemical plants are key fire protection points. The characteristics of fires in such places are: large fire, high temperature, and rapid spread. Ordinary fire doors and walls are difficult to withstand such high temperatures and pressures. Ordinary walls are made of concrete structures, which are not resistant to high temperatures. At the same time, the wall thickness is large, occupying a large amount of space. Metal steel plate walls are building components installed in industrial plants such as nuclear power plants and chemical plants to replace traditional reinforced concrete walls. Where the wall thickness or strength does not meet the standards, steel plates should be used for protection. Metal steel plate walls provide fire isolation for adjacent building areas, ensure the maintainability of equipment during fires, meet the requirements of the passability of evacuation routes, and have functions such as earthquake resistance, impact resistance, and fire protection. They play an important role in actual use. However, the existing technologies have the following deficiencies in use:

[0003] When most existing steel plate walls are actually in use, in case of an accidental fire, their fire prevention and high-temperature resistance are poor. The steel plate walls will quickly transfer the temperature, which will cause the place in contact with the steel plate protection wall to catch fire, resulting in the things stored inside being burned.

[0004] Therefore, there is an urgent need for a steel plate wall with fire and heat insulation functions to solve the above problems. Summary of the Utility Model

[0005] The purpose of the present utility model is to address the problem that when most existing steel plate walls are actually in use, in case of an accidental fire, their fire prevention and high-temperature resistance are poor.
