It will be readily appreciated that the nodes herein refer to points of weakness in the wallboard that are points of weld of the steel skeleton 17.
The buffer top plate 4 is arranged along the top of the buffer wallboard and is respectively connected and fixed with the first side wall buffer wallboard 1, the second side wall buffer wallboard 2 and the rear wall buffer wallboard 3. The buffer top plate 4 can effectively prevent the concrete blocks which are caving after the explosion-proof room is broken from caving along the top, and plays a role in integrally reinforcing the explosion-proof room.
Referring to fig. 3, the buffering top plate 4 has the same specific structure as the buffering wall plate, and comprises a steel skeleton 17, a protecting cover 16, a plurality of elastic supporting pieces 5 and a plurality of buffering members 6. And the protective cover 16 is coated on the outer surface of the steel skeleton 17, so that fine crushed concrete of explosion-proof room collapse can be blocked. A plurality of elastic supports 5 are vertically supported on at least a portion of the nodes of the steel skeleton 17, so as to improve the shearing resistance of the buffer roof 4 under the action of the blast shock wave.

In some embodiments, since the intersection point of the transverse steel bars and the longitudinal steel bars of the steel skeleton 17 is a stress weak area, bending damage and shearing damage easily occur, the elastic supporting piece 5 and the buffer member 6 of the present invention are all arranged along the intersection point of the transverse steel bars and the longitudinal steel bars of the steel skeleton 17, so as to comprehensively promote the bending shearing force of the wallboard and the top plate.
Referring to fig. 1 to 3, the elastic supports 5 and the buffering members 6 are disposed in rows at the crossing points of the transverse and longitudinal reinforcing bars of the buffering wallboard and the buffering roof 4, and the elastic supports 5 and the buffering members 6 are disposed at intervals in rows.
