Membrane structure landscape Radiation heating relies on radiation and heat conduction. The heat energy emitted from the heater is first transmitted to the external surface of the workpiece in the form of radiation, and then it is conducted from the external surface to the internal by metal conduction. Therefore, Membrane structure parking shed The characteristic of radiation heating during construction is that a temperature difference must be established between the outside and inside of the workpiece, so that heat can be transferred from the outside to the inside, which is the heating process. The greater the temperature difference, the faster the heat transfer, and the shorter the time to reach the specified temperature.
During the construction of parking shed, this heating method is to heat the surface of workpiece by the conduction and radiation of flame heat, and then conduct it to the deep wall thickness. During the construction of the membrane structure parking shed, the power frequency induction heating is conducted through the induction coil, and the frequency of the AC power is 50Hz. Four sets of BX-500 or BX2-1000 AC welding machines can be used in parallel. Gas flame heating method This heating method is to heat the surface of the workpiece by the conduction and radiation of flame heat, and then conduct to the deep wall thickness. Gas flame heating shall be selected.
Summary of safety of membrane structure: the light tension membrane structure designed according to the existing national specifications and guidelines has sufficient safety. Light structures can maintain good stability under horizontal loads such as earthquake. Due to the light weight of light structures, even if accidental collapse occurs, its risk is smaller than that of traditional building structures. When the membrane structure is torn, if the structural arrangement can ensure that the rigid supporting members such as masts and beams will not collapse, the risk will be smaller.
With the acceleration of urban modernization, cars have become an indispensable means of transportation in any city. Due to the rapid development of the automobile industry in China, the number of cars owned in cities has doubled, but the urban construction planning has not been able to meet the requirements of this development as soon as possible, and there is often no parking place for cars. Therefore, the parking lot should be fully considered in the planning of the construction cluster, and the construction and planning of the parking lot as an important part of modern urban construction planning has become increasingly important. Similarly, membrane structure also plays an important role in the construction of parking lots.
The membrane structure parking shed has good light transmission capacity, and the light transmission rate reaches 13%. Other types of car sheds, such as color steel plates, have poor light transmission, resulting in yellowing and damage of the shed due to prolonged exposure to the sun. However, the high light transmission rate of the membrane structure ensures that it will not have such problems, which also extends its service life from the side. The weight of the membrane structure parking shed is particularly light. In addition, the design of the membrane structure parking shed is an architectural fabric, which can deform at will and withstand high strength impact, while the metal material parking shed can not be extended and stretched at will, which is also a reason for the longer service life of the membrane structure. Therefore, we give the membrane structure the laudatory name of "unbreakable glass".
