Abstract
The invention relates to a movable blast wall. The body of the blast wall comprises a wall body core, a shear thickening material layer and a protective outer layer, wherein the protective outer layer is enwrapped outside the wall body core; the shear thickening material layer is positioned between the wall body core and the protective outer layer; and a fixing bracket is arranged under one side of the body of the blast wall. In the invention, a shear thickening material is used so as to largely reduce the mass of the blast wall and realize quick assembly, disassembly and movement. The used shear thickening material is a novel intelligent material which comprises shear thickening liquid, shear thickening gel and the like. The shear thickening material is soft generally and has easy fluidness in normality; in the assembly process, shear thickening materials of two blast walls are mutually fused so that both of the blast walls form a whole to enhance explosion-proof effect. Once impacted by high strength, the shear thickening materials become abnormal hard, absorb a large quantity of impact energy in the process, and have good explosion-proof effect.
Description
Technical field
The invention belongs to ability with explosion-proof shock wave, can be with the destruction restriction blast wall technical field within the specific limits of blast, the blast wall that is specifically related to a kind of light, high strength and has extremely strong absorption impact capacity.
Background technology
The mankind enter 21 century, and terrorism is becoming increasingly rampant.Car bomb, body bombs, time bomb or the like serious threat is destroying people's normal life order to people's the security of the lives and property.Blast wall can reduce the harm that the attack of terrorism brings effectively as a kind of anti-explosion product.Traditional blast wall mainly contains steel concrete blast wall, steel plate blast wall, shaped steel blast wall and brick blast wall, and these blast walls can not change with the variation of spot.
Summary of the invention
In order to solve the deficiency that traditional blast wall can not change with the variation of spot, the invention provides a kind of packaged type blast wall that can assemble apace according to the variation of spot.
The technical solution that realizes the foregoing invention purpose is as follows:
The packaged type blast wall comprises the blast wall body of wall, and described blast wall body of wall is formed by body of wall core, shear thickening materials layer and protection are outer, and the protection skin is wrapped in body of wall core outside, and the shear thickening materials layer is between body of wall core and protection skin; Blast wall body of wall one side lower part is provided with fixed support; Described body of wall core material is a Reinforced Concrete Materials, and described shear thickening materials is shear thickening liquid or shear thickening gel.
Described fixed support comprises hound and triatic stay; One end of described hound is connecting middle part, blast wall body of wall one side, and the other end is connecting the triatic stay middle part, and described triatic stay one end is connecting bottom, the described side of blast wall body of wall, and triatic stay is perpendicular to the blast wall body of wall.
Described support bracket fastened hound top is provided with attenuator.
Described protection superficies are provided with the fire-proof heat-insulating material layer.
Useful technique effect of the present invention is embodied in following several aspect:
1, the present invention has used shear thickening materials, and the blast wall quality is reduced greatly, realizes assembling fast, dismantling and move.
2, the shear thickening materials of the present invention's use is a kind of novel intellectual material, comprises shear thickening liquid and shear thickening gel etc.Softness very has easy mobility under the normality at ordinary times, and the shear thickening materials of two blast walls is merged mutually, makes each blast wall become as a whole, strengthens explosion-proof effect; It will become unusual hard in case suffer high-intensity impact, and absorb a large amount of impact energys in this process, and explosion-proof effect is very good.
Description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is a structure sectional view of the present invention,
Fig. 3 has the schematic diagram of attenuator for the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done to describe further by embodiment.
Embodiment 1:
Referring to Fig. 2 and Fig. 3, the packaged type blast wall comprises blast wall body of wall 1.Blast wall body of wall 1 is made up of body of wall core 4, shear thickening materials layer 3 and protection outer 2, sees Fig. 2; Protection outer 2 is wrapped in body of wall core 4 outsides, and shear thickening materials layer 3 is between body of wall core 4 and protection outer 2; Body of wall core 4 is a Reinforced Concrete Materials, and shear thickening materials is shear thickening liquid or shear thickening gel.Blast wall body of wall 1 one side lower parts are equipped with fixed support, and fixed support comprises hound 5 and triatic stay 7; One end of hound 5 is connecting middle part, blast wall body of wall 1 one sides, and the other end is connecting triatic stay 7 middle parts, and triatic stay 7 one ends are connecting blast wall body of wall 1 this bottom, side, and triatic stay 7 is perpendicular to blast wall body of wall 1.Be provided with the fire-proof heat-insulating material layer on outer 2 surfaces of protection.
When needs prevention car bomb, time bomb etc. attacked, blast wall of the present invention can must be assembled into the polylith blast wall integral body rapidly, referring to Fig. 1.If impacted, the shear thickening materials 3 of explosion-proof body of wall inside will become hard unusually and absorb lot of energy in this process, and body of wall core 4 also can absorb part energy.Remaining impact energy will pass to ground by fixed support.
Embodiment 2:
Referring to Fig. 3, support bracket fastened hound 5 tops are equipped with attenuator 6.Other structure is with embodiment 1.
When blast wall was subjected to impacting, blast wall body of wall 1 can absorb the energy of a part earlier, was absorbed the energy of a part then again by attenuator 6, and remaining impact energy just passes to ground by fixed support.
