Description
Technical field
The application relates to a kind of bionical blast wall.
Background technology
Precision and the power of tech war conventional weapon improve greatly, process essence is led Weapon-damaged warship precision and is reached within 1 meter, long-range essence leads Weapon-damaged warship precision also within 10 meters, and also improving constantly, the quality of conventional ammunition powder charge is in improve, explosive payload is also in increasing, and the penetration technology particularly for underground construction is improved greatly.The intensity that command system and common-denominator target preventive works are subject to precision strike is larger, and underground construction survival ability is subject to serious threat.In addition, accident and terrorist activity also constitute threat to safety.Therefore, further raising is asked to the anti-strategically located and difficult of access of building.Existing solution normally builds the blast wall such as brick wall or reinforced concrete wall, and these walls, when being subject to powerful shock wave, existing body of wall and break, the danger that fragment splashes.And individual layer blast wall is very limited to the damping capacity of explosion wave, shock wave can cause the destruction of other targets and the injury of personnel after blast wall through the air superpressure caused after body of wall.
Utility model content
The purpose of this utility model is the bionical blast wall providing a kind of high-strength light and construct fast, and this blast wall effectively can resist Blasting shock wave, avoids body of wall to break and fragment splashing.This body of wall overcomes the defect of conventional monolayers blast wall, is consumed energy by multiple defence line, effectively reduces the injury of shock wave to blast wall internal object and personnel.
For achieving the above object, a kind of bionical blast wall, be made up of FRP overcoat and body of wall, wherein FRP overcoat is by fish scale-shaped FRP layer, rubber layer and polyurethane foam layer composition, body of wall is high strength RC wall or prestressing force building block build shearing force wall, FRP overcoat is positioned at wall external layer, fish scale-shaped FRP layer is positioned at FRP overcoat outermost layer, rubber layer is between fish scale-shaped FRP layer and polyurethane foam layer, polyurethane foam layer is between rubber layer and body of wall, body of wall is the skeleton of this component, be positioned at blast wall innermost layer, fix with glue or bolt between FRP overcoat and body of wall, fish scale-shaped FRP layer, fix with glue or bolt between rubber layer and polyurethane foam layer.
Further, fish scale-shaped FRP layer is formed by adhering with epoxy resin in its junction by fish scale-shaped FRP sheet.
Further, fish scale-shaped FRP sheet is that cloth is by the epoxy resin impregnated shaping fish scale-like made.
Further, the fish scale-shaped FRP sheet arrangement mode on fish scale-shaped FRP layer is the imbricate arrangement of flap.
Further, high strength RC wall concrete used is high-strength concrete.
Further, prestressing force building block build shearing force wall applies pressure by presstressed reinforcing steel to masonry wall.
The utility model compared with prior art, is abandoned the design philosophy of " with firm gram just " in conventional design, but is adopted multiple defence line, couple hardness with softness.Fish scale-shaped FRP skin has used for reference overlaying structure and the mechanics principle of flap, and make use of the good shock resistance of FRP material, resistance to elevated temperatures, be the anti-impacting layer of this component simultaneously; Rubber layer is the energy ezpenditure layer of this component; Polyurethane foam layer utilizes the energy absorption characteristics of polyurethane foam plastics, is the energy attenuation layer of this component; Body of wall is the skeleton of this component, can effectively consume residue impact energy, guarantees that can not be formed with lethal fragment flies out simultaneously.Than conventional steel concrete blast wall, under equal requirement of shelter, the thickness of this bionical blast wall can reduce 30%-50%, saves the materials such as steel concrete, has good promotion prospect.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described further:
Embodiment 1:
Specific embodiment of the utility model is described in detail below in conjunction with accompanying drawing.Fig. 1 is that in the utility model, body of wall is the perspective view of high strength RC wall.Wherein, the blast wall that the utility model provides is made up of two parts, FRP overcoat and body of wall.As shown in Figure 2, FRP overcoat is made up of fish scale-shaped FRP layer, rubber layer and polyurethane foam layer.Fish scale-shaped FRP layer has high temperature resistant and shock proof good characteristics, is desirable protective materials, and it has used for reference the imbricate structure of flap, better can resist impact load.Fish scale-shaped FRP layer is, with impregnated resin, cloth is made fish scale-like, and is pasted onto in one deck cloth according to the imbricate structural arrangement mode of flap.Cloth type can be selected according to concrete requirement of explosion proof.According to the difference of applied environment, size and the thickness of suitable fish scale-like FRP can be selected in actual application.
Rubber layer is close to fish scale-shaped FRP layer, and rubber layer has certain Rigidity and deformation ability, in explosion wave transmittance process, effectively can consume explosion energy.In the present embodiment, the optional 30mm of the thickness of rubber layer.Can difference environmentally in actual application, select suitable thickness.
Polyurethane foam layer next-door neighbour rubber layer, it has good energy absorption characteristics, is the shock wave energy decay passed through effectively.In the present embodiment, polyurethane foam layer thickness is chosen as 60mm.Can difference environmentally in actual application, select suitable thickness.
High strength RC wall next-door neighbour polyurethane foam layer.High-strength concrete has the intensity of superelevation, the toughness of superelevation and the durability of superelevation, and little compared with ordinary concrete quality.Therefore, it is particularly suitable for blast resistant construction.High strength RC wall is the skeleton of the blast wall that the utility model provides, and can effectively consume residue impact energy, guarantees that can not be formed with lethal fragment flies out simultaneously.In the present embodiment, the thickness of high strength RC wall is chosen as 200mm.Can difference environmentally in actual application, select suitable arrangement of reinforcement and thickness.
Based on the utility model-a kind of bionical blast wall of above-mentioned design, its material is divided into four layers, effectively can stop the transmission of shock wave, ensures indoor safety, and this blast wall high-strength light, easy construction.Fish scale-shaped FRP layer not only can be attached on newly-built wall, also can be attached on built wall, for reinforcing existing building.In sum, the feature that blast wall of the present utility model has high-strength light, constructs fast, and there is obvious practicality.
Just preferred embodiment of the present utility model described in this manual, above embodiment is only for illustration of the technical solution of the utility model but not to restriction of the present utility model.All those skilled in the art comply with design of the present utility model by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should within scope of the present utility model.
