Description

Technical Field

[0001] The utility model relates to the technical field of steel structure pressurized buildings, and particularly relates to a heat preservation structure suitable for steel structure pressurized buildings. Background Technique

[0002] Pressurized buildings are mostly assembled with prefabricated steel structures and are suitable for high-altitude areas. Due to reasons such as climate and relevant building code requirements, the heat preservation structure of the building needs to be considered during construction. The existing building heat preservation forms mainly include internal heat preservation, external heat preservation, and hybrid heat preservation. The internal heat preservation technology refers to using prefabricated heat preservation materials to paste, splice, plaster on the inner surface of the exterior wall or directly make a heat preservation mortar layer to achieve the purpose of heat preservation. The internal heat preservation is relatively simple in technology and convenient for construction, with advantages such as fast construction progress and relatively low cost. However, there are structural thermal bridges, resulting in local condensation, which causes the wall surface to mildew and crack. External heat preservation refers to the technology of heat preservation on the outer surface of the exterior wall, which usually consists of a heat preservation layer, a protective layer, and fixing materials (adhesives, anchor bolts, etc.). Because it can reduce the influence of thermal bridges and at the same time protect the exterior wall from excessive temperature deformation stress, it is the most widely used heat preservation method at present. However, this heat preservation form has strict requirements for the heat preservation system. Since the external heat insulation system is placed on the outer side of the exterior wall and directly bears the influence of various external factors, higher requirements are put forward for the external heat preservation system. In addition, the external heat preservation construction process is cumbersome, the construction difficulty is large, and the cost is high. The internal and external hybrid heat preservation means using external heat preservation in the parts where external heat preservation is convenient for operation and using internal heat preservation in the parts where external heat preservation is inconvenient for operation. From the perspective of construction operation, the internal and external hybrid heat preservation can effectively improve the construction speed and effectively protect the thermal bridge parts that cannot be protected by the internal heat preservation of the exterior wall, so that the building is in heat preservation. However, the external heat preservation method makes the wall mainly affected by the room temperature, and the temperature difference deformation generated is small; the internal heat preservation method makes the wall mainly affected by the outdoor temperature, so the temperature difference deformation generated is relatively large. Using the hybrid heat preservation method combining internal and external heat preservation is likely to cause different parts of the exterior wall to deform at different speeds and sizes, making the structure in a more unstable state, easily causing structural deformation and cracks, thereby shortening the service life of the building.

[0003] As can be seen from the above, the existing heat preservation forms have many disadvantages and are not suitable for steel structure pressurized buildings. Therefore, the utility model provides a heat preservation structure suitable for steel structure pressurized buildings. Content of the Utility Model
