Abstract
The utility model discloses a composite material anti dashing housing, which comprises two pieces; the shape is fitted with the pier outer shape, the housing is enclosed on the outer surface of the pier; a housing core (6) is a light weight concrete, Kevlar-Aramid Fiber clothe (7) is glued on the core (6) surface, the high elastic rubber (4) is arranged on the outer layer; a glass fiber cloth (3) is enclosed and glued on the most outer layer, which makes the whole housing into a whole body. The utility model composite material anti dashing housing adopts hardness and softness mutual reinforced manner to integrate multi materials, the housing can not only have high strength, but also have a good show of shocking resistance performance and impact energy absorbing performance, the quality is reinforced compared with the conventional steel plate but is more light, the utility model is convenient to construct and install, is most applicable to be arranged on the piers of the road bridges, the elevated highway bridges and the river bridges, can protect the piers effectively to avoid the damage from the impact.
Description
[technical field]
The utility model relates to a kind of composite anti-collision housing, is particularly suitable for being installed on the bridge pier of road bridge, viaduct and river course bridge, can well protect bridge pier, makes it exempt from bump and causes damage.
[background technology]
In recent years, along with expanding economy, being surging forward of communications and transportation, vehicle, boats and ships constantly increase the collision accident of bridge, make broad masses of the people's lives and properties and important foundation facility be subjected to very big harm.
Traditional method increases the sectional area or the affixing steel plate of bridge pier often, increases the impact resistance of bridge pier with this, asks for an interview " monitoring of building, evaluation, strengthening and reforming " that metallurgical industry publishing house publishes in detail.But the construction costs height of these methods, the construction technology complexity, long construction period, bridge pier still can be subjected to certain infringement when suffering vehicle, ship collision.
Present also have the method that adopts carbon fiber, aramid fiber textile impregnation resin to wrap up bridge pier that bridge pier is carried out the crashworthiness protection, with reference to " application of composite material in building reinforce, reparation " of Chemical Industry Press's publication.Though the method can increase resistance to compression, the shear strength of bridge pier, because fabric becomes one with bridge pier after resin-bonded, after being clashed into, bridge pier still can cause damage to bridge pier, the security performance of bridge is exerted an influence.
[summary of the invention]
The purpose of this invention is to provide a kind of composite anti-collision housing, be installed on the bridge pier of road bridge, viaduct and river course bridge, the infringement problem that the bump that can make bridge pier exempt from vehicle, boats and ships causes.
A kind of composite anti-collision housing, housing is two, shape and bridge pier profile adapt, be packaged in the outside of bridge pier etc., adopt the core of light cement as housing, the aramid fiber fabric is pasted on the core surface, and skin is elastomeric elastomeric material, outermost layer is pasted parcel with glass fabric, makes whole housing become as a whole.
Above-mentioned composite anti-collision housing can be strengthened chemical fibre dimension resin muscle as reinforcement material in the light cement of core.
Above-mentioned composite anti-collision housing, housing and bridge pier have certain clearance, can not damage bridge pier after being clashed into.
Above-mentioned composite anti-collision housing, housing is demountable, after housing is subjected to serious impact damage, replaceable new crashproof housing.
Composite anti-collision housing of the present utility model; adopt the method for both steel and soft that multiple material is combined; not only intensity is very high to make housing; and also has good performance aspect shock resistance, the absorption impact energy; the steel plate reinforcement that its quality is also more traditional is gently a lot, is convenient to construction and installation, is particularly suitable for being installed on the bridge pier of road bridge, viaduct and river course bridge; can well protect bridge pier, make it exempt from bump and cause damage.
[description of drawings]
Fig. 1 is the schematic diagram of the utility model composite anti-collision housing;
Fig. 2 is the sectional view of the utility model composite anti-collision housing;
[specific embodiment]
Composite anti-collision housing of the present utility model, the core of housing light cement material, its density is 1.07g/cm
2Intensity and ordinary Portland cement are suitable.Strengthen chemical fibre dimension resin (FRP) muscle in the light cement as reinforcement material, the FRP muscle has many advantages: its relative density is 1.8～2.1, and tensile strength is 450～600Mpa, is used in the light cement, can further increase the shock resistance of core.The aramid fiber fabric is pasted on the core surface, and aramid fiber has the characteristics of high strength, high elastic modulus, compares with carbon fiber, and its shock resistance is better, and after core was pasted aramid fiber, the performance of its shock resistance and absorption impact energy was strengthened.The elastomeric elastomeric material of outer use, it can absorb impact energy, and the protection housing is not damaged.External surface sticking glass fabric makes total become as a whole, and is specious, and anti-time, the acid-proof alkaline of housing are further strengthened.After two halves wrapped in outside the bridge pier, skin was pasted the layer of glass fabric again, and housing is fixedly mounted on the bridge pier.
Among Fig. 1,1 is the composite anti-collision housing, and 2 is bridge pier, and after composite anti-collision housing 1 was wrapped on the bridge pier, the surface was fixed with epoxy resin sticking glass fabric.Among Fig. 2,3 is glass fabric, and 4 is elastomeric elastomeric material, and 5 is the FRP muscle, and 6 is core, and 7 is the aramid fiber fabric.Use mould molding light cement core 6 earlier, imbed in advance and strengthen FRP muscle 5, cement solidification was pasted aramid fiber fabric 7 on core 6 surfaces with epoxy resin after seven days, behind the resin solidification seven days, elastomeric elastomeric material 4 is glued with epoxy resin in the surface, resin solidification after seven days external surface paste parcel glass fabric 3 and make into as a wholely, promptly make the composite anti-collision housing after the curing.During installation, after two halves close, can fix with anchor clamps earlier, adopt epoxy resin sticking glass fabric 3 then on the surface, take off anchor clamps behind the resin solidification and get final product.But surface brushing paint or cement mortar protective course are protected housing, strengthen the durability of housing.
Claims (3)
1, a kind of crashproof housing, housing is two, shape and bridge pier profile adapt, be packaged in the outside of bridge pier etc., it is characterized in that: adopt the core (6) of light cement as housing, aramid fiber fabric (7) is pasted on core (6) surface, and skin is elastomeric elastomeric material (4), outermost layer is pasted parcel with glass fabric (3), makes whole housing become as a whole.
2, crashproof housing according to claim 1 is characterized in that: strengthen chemical fibre dimension resin muscle (5) in the light cement of core (6) as reinforcement material.
3, crashproof housing according to claim 1 and 2, it is characterized in that: housing and bridge pier have certain clearance.
