Description
Technical field
The present invention relates to a kind of walltile safeguard structure, specifically relating to one can resist high speed impact, a kind of walltile safeguard structure with shellproof explosion prevention function.
Background technology
At present, most protective building (military installations, government facility, embassy, nuclear power station etc.) all form with steel concrete construction, and generally take to improve concrete strength, strengthen the anti-high speed impact ability that structural element (wall, the post etc.) method such as thickness and reinforcement ratio carrys out reinforcement self.Along with the development of science and technology, conventional weapon power increases day by day, C50 concrete is under 12.7mm armor-piercing incendiary penetration effect, invade and deeply can reach 15-20cm (about 800m/s Shi Keda about 25cm), and test proof concrete strength is increased to a certain degree very little to the contribution of reduction Penetration Depth afterwards, the contribution that reinforcement ratio increases reducing Penetration Depth also not quite even can increase the weight of destructiveness.So the impact resistance that the method by infinitely improving concrete strength or vast scale increase scantling or reinforcement ratio increases the component such as wall or post is both inconvenient, also impracticable.
In the past, defensive function and civilian construction were not directly related.Relative to fortification, owing to considering economy and applicability, the wall thickness of civilian construction and column cross-section size are often less, and reinforcement ratio is also less.But in recent ten years, along with external with civilian construction (house, school, office building etc.) for the attack of terrorism growing number of target increases, riddled with gaping wounds explosion scene even changed beyond recognition discloses existing civilian construction and can not meet people to staying in indoor with the demand of seeking asylum.Although China's attack of terrorism case is little, but the residential building of artificial manufacture in part criminal case or office building bomb blast, also have the building destruction caused because of chemicals or liquefied gas blast of frequent report in recent years or collapse, equally irretrievable loss being caused safely to the people's lives and property; Therefore, people reveal increasing worry to the overall security issue table of building under Impact Load around inhabitation and working environment.And, due to the fragility feature that the constructional materials such as concrete or common brick is intrinsic, make existing wall body structure, under Impact Load, comminuted destruction may occur.The shell fragment produced in impact process or concrete fragment will splash, and form larger secondary kill and wound threat to personnel inside and outside structure and equipment.
So we wish the toughness and the nonelastic deformation ability that increase the important component such as body of wall and post, postpone body of wall and the breaking-up time of post under high speed impact, more escape the time to personnel inside and outside building.If toughness and the robustness of structural element can be improved, make body of wall still can keep globality under shock wave, then body of wall may be avoided to be worn out by shell fragment, reduce the secondary lethality of breakage simultaneously.
In order to improve the toughness of concrete material, lot of domestic and international scholar is conceived to fibre reinforced concrete composite material in recent ten years, comprises steel fibre, polypropylene fibre, polyethylene fibre etc., and obtains a series of achievement in research.Test proves that the inhibitory action of steel fibre fracture is better than other fibers, but is applied to engineering material, and cost is higher.Some researchers, by adding nanofiber or nanotube in concrete, obtain the conclusion that can suppress initial nanoscale crack completely, but identical test are but difficult in the laboratory of other scholars obtain same result of the test.Also scholar is had to arrange that the test of gauze wire cloth is reached a conclusion by the place of layer on concrete test block is close: to arrange that the anti-bullet impact performance of the concrete test block of gauze wire cloth is better than steel fiber reinforced concrete test block.Although arrange gauze wire cloth relatively economical, engineering practical operation bothers and often runs into Surface layer's concrete or cement mortar and gauze wire cloth due to the tightly situation about departing from that bonds.At present, what in shock resistance constructional materials, research was newer is ECC (engineeredcementitious composites) and cement based Functionally Graded Materials, the impact resistance of ECC material need experimental verification and also the cost of material own higher, can't extensive use.Cement based Functionally Graded Materials can produce after a bullet strike to be heaved, and reduces the protection probability of anti-multiple strike.Multilayer materials early has application in shock resistance, and especially in military field, or ceramic base Functionally Graded Materials composite armour armoring to Al2O3 ceramet MULTILAYER COMPOSITE has a lot of investigation and application both at home and abroad.But in concrete building structures, research about cement based multilayer materials or structure is less, invents comprising Michael Schmitz in 2004 the lamination concrete slab (patent No. is US 20040231273A1) that a kind of multilayer materials (patent No. is US 006790544B2) and Guy Bamford in 2004 invent.
Bionical concept is long-standing with research, is widely used in the field such as engineering and medical science, but for emphasizing the field of civil engineering of macroscopic view and non-precision construction, this concept is but often out in the cold.The nacre composition of abalone shells is very simple, and but have excellent mechanical property, most scholar thinks that the microcosmic laminated construction of nacre is primary influence factor.Shi Shaoqing etc. take a hint from the structure of shell pearl layer, have developed honeycomb steel tube constraint concrete safeguard structure (letters patent book number is ZL 03233831.7), think that the hoop effect of steel pipe can increase concrete compressive strength greatly, and interlayer interlaced arrangement serves deflecting action to crackle.Although the surface structure of its cellular safeguard structure is imitative shell, structural principle is but different from shell.It needs to be probed into " deflecting action " of crackle.Shell utilizes " weak " layer to carry out guiding crack deflection, and not obvious " weak " layer of honeycomb steel tube constraint concrete safeguard structure, crackle is probably that " stopping " is in side direction steel pipe.The bone of human body and tendon have very high toughness equally, but constituent and structure more complicated.The present invention obtains design enlightenment, in order to improve the ability of the anti-high speed impact of construction wall or post (built or newly-built) from the Partial Feature of nacre and tendon.
