In order to ensure that the shelter has a larger internal space during use and can be easily transferred during transportation and transfer, the shelter needs to have the function of expanding and changing its shape. The existing double-sided expansion shelter lacks auxiliary support structures on both sides of the shelter after expansion, so that the support stability and support strength of the two sides of the shelter are not high after expansion, which reduces the service life and safety of the shelter.
