Problems solved by technology

The main structure of the tank body is prone to local damage when subjected to contact blasting or close-range blasting, which in turn affects the overall stress function of the main structure and the safety of energy storage.
[0004] The existing practice of the main structure of the tank body in our country lacks comprehensive, sufficient and effective anti-knock measures for terrorist attacks by conventional weapons

Embodiment 1

[0021] A general anti-terrorist anti-explosion device, such as figure 1 , figure 2 As shown, the outer layer or inner layer of the structural main body 5 arranged in the flammable and explosive concrete storage tank or building facilities includes a force-bearing member 3, and the force-bearing member 3 is fixedly connected or integrally formed with the structural main body 5, and the force-bearing member Both sides of 3 contain a grid structure, and the shape of the grid is not limited to rectangle, it can be other polygons, and any grid structure includes grid protrusions 4 around; An explosion panel 1 is filled with an anti-explosion filler 2 between the grid structure and the anti-explosion panel 1; the anti-explosion panel includes an assembled protective structure. The protrusion height of the grid protrusion 4 is not less than 200 mm. On the one hand, there is enough space to place the anti-explosion filler 2. On the other hand, when the grid structure on both sides o...

Embodiment 2

[0025] Such as Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the force-bearing member 3 only includes a grid structure on its outer side, and the anti-explosion plate 1 is embedded between the grid structures, and the gap between the anti-explosion plate 1 and the grid structure is Filled with anti-knock filler. Compared with Embodiment 1, this embodiment makes full use of the grid structure of the force-bearing member 3 and is suitable for low-intensity anti-knock environments.

[0026] Such as Figure 8 As shown, the outer surface of the anti-explosion plate 1 is provided with a pre-embedded hanging groove 10, and a pendant installed horizontally on the wall of the groove is arranged in the pre-embedded hanging groove 10, and the explosion-proof external hanger is articulated by the pendant to form a high-explosion-proof performance. Components, the explosion-proof components can form anti-terrorism and explosion-proof facilities again...

Embodiment 3

[0028] Such as Figure 9 , Figure 10 As shown, the grid protruding part of the force-bearing member 3 is provided with a pre-embedded steel bar 12, and a steel bar structure is also provided in the anti-explosion panel 1 to enhance its overall firmness. After the reinforcement structure is connected, the concrete 11 is poured to fix and form a whole.

Abstract

The invention provides a universal anti-terrorist anti-explosion device for important structural bodies such as various inflammable and explosive storage tanks and strategic target buildings. The anti-terrorist anti-explosion device is characterized by being arranged on the outer layer of a structure main body of the inflammable and explosive storage tanks or the strategic target building facilities, the anti-terrorist anti-explosion device comprises a stress component, the stress component and the structure main body are fixedly connected or integrally formed, the stress component comprises grid structures, grid convex parts are arranged on the periphery of any grid structure, and the grid shape is not limited to a rectangle, and can be other polygons; an anti-explosion plate is arrangedon the exterior of the stress component, and anti-explosion filler fills the portion between the grid structures and the anti-explosion plate; and the anti-explosion plate comprises an assembled protection structure. The universal anti-terrorist anti-explosion device has the beneficial effects that a complete protection layer for the main body structure is formed, the energy of shock waves is absorbed by utilizing deformation of the anti-explosion plate and the anti-explosion filler, so that direct and indirect damage to the main body structure under the action of the shock waves is relieved.

Description

technical field [0001] The invention relates to anti-explosion device technology, in particular to a general anti-terrorism anti-explosion device. Background technique [0002] At present, important buildings, important material transportation devices, and storage warehouses for flammable and explosive materials are poorly protected, and their protection strength is flawed, such as liquefied natural gas (LNG) storage tanks or large and extra-large liquefied natural gas (LNG) storage tanks. There are three main types of tanks: single-capacity, double-capacity, and full-capacity, all of which are circular thin-walled dome structures. Except for the reinforced concrete top shell of the full-capacity type, the single-container and double-capacity types have steel structure roofs. Both the tank wall and the tank roof are continuous large-scale thin-walled components, with few component constraints and insufficient blast resistance. Now, in order to increase the blast resistance, ...
