This invention belongs to the field of civil defense engineering and explosion-proof protection technology, and relates to a polyurea-coated, panelless civil defense device, including a load-bearing outer panel, a reinforcing frame, elastic damping connectors, an internal cast-in-place body, an arc-shaped elastic support rod, and a support plate. The support plate's inner side contacts the arc-shaped protruding surface of the arc-shaped elastic support rod, forcing the rod to undergo elastic compression deformation. The arc-shaped structure of the support rod produces a progressive stiffness response under pressure: initially, the arc-shaped structure is easily deformable, providing a large displacement stroke to absorb energy; as the compression increases, the stiffness of the support rod gradually increases, effectively suppressing excessive deformation. During deformation, the arc-shaped elastic support rod generates a reaction force on the reinforcing frame, which is evenly distributed to the internal cast-in-place body through the three-dimensional mesh structure of the reinforcing frame. Its structural design is scientifically sound, easy to use, provides excellent protection, and is environmentally friendly.
