Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] like figure 1 , image 3 and Figure 5 As shown, a telescopic flexible quadrangular pyramid sandwich structure for underwater explosion energy dissipation includes two metal panels 1, a plurality of hemispherical nodes 2 respectively arranged on the opposite surfaces of the two metal panels 1 and clips. The core rod, the hemispherical node 2 is a steel hemisphere with four symmetrical connection points on the spherical surface; one end of the four sandwich rods is connected to a hemispherical node 2 on one of the metal panels 1 The points are connected to form a quadrangular pyramid unit with the hemispherical node 2 as the apex. The other ends of the four sandwich rods are respectively connected to the connection points of the four hemispherical nodes 2 on the opposite metal panel 1. A single quadrangular pyramid unit There are five hemispherical nodes 2 ins...
