Specific embodiment
As shown in Figure 2, Figure 3 and Figure 4, a kind of modular composite anti-collision facility, including anti-collision facility cell cube；Institute
Anti-collision facility cell cube 1 is stated in " case " shape, 1 surface of anti-collision facility cell cube covers one layer of composite layer 1-1, institute
Stating 1 laid inside of anti-collision facility cell cube has inside framework of steel reinforcement 1-2, the framework of steel reinforcement 1-2 filled with energy consumption closed-cell materials
6, the energy consumption closed-cell materials 6 are connected with the closing of composite layer 1-1 inner walls.Wherein, the present invention with the present invention with anti-collision facility
Cell cube 1 is the theme, and the anti-collision facility cell cube 1 is that a kind of anti-impact for being used for protecting bridge pier presses assembly.The anticollision is set
It applies cell cube 1 and is presented " case " shape, it is simple in structure, be convenient for carrying.The anti-collision facility cell cube 1 is reduced and surrounding enviroment
All corner angle have been carried out chamfering by contact.In order to enhance internal structure and do whole setting, the anti-collision facility cell cube 1 exists
Inside has added the energy consumption closed pore material for being filled with inside framework of steel reinforcement 1-2, the framework of steel reinforcement 1-2 and being used for waterproof sealing
Material 6.The energy consumption closed-cell materials 6 are made of ingredients such as polystyrene, and conventional composite materials anticollision is avoided using this material
The shortcomings that facility crashworthiness is poor, while avoid the shortcomings that steel jacket box easily corrodes.Framework of steel reinforcement 1-2 is embedded in energy consumption and closes
Inside Porous materials 6, do not contacted with air；Impact resistance is strong, and framework of steel reinforcement 1-2 is embedded in inside energy consumption closed-cell materials 6, in soft
Strip, first soft rear steel, by adjusting the spacing of reinforcing bar or the thickness of reinforcing bar in framework of steel reinforcement 1-2, can adjust anticollision easily
The crashworthiness power of facilities units body 1.One layer of composite layer 1-1 is with the addition of in the outer surface of the framework of steel reinforcement 1-2, it is described multiple
Condensation material layer 1-1 quality is harder, and surface is smooth, and the impact force that can effectively bring tide is effectively dissolved, in order to avoid because of length
The impact of time brings damage to framework of steel reinforcement 1-2 and energy consumption closed-cell materials 6.
As shown in Figure 1 and Figure 2 and Figure 3, the composite layer 1-1 front surfaces are fitted with two pieces of polyethylene tetrafluoro slide plates
2, the 2 face bridge pier 8 of polyethylene tetrafluoro slide plate, the framework of steel reinforcement 1-2 front surfaces be equipped with the first built-in fitting 4, described first
Built-in fitting 4 is fixedly connected by bolt through composite layer 1-1 with polyethylene tetrafluoro slide plate 2.Wherein, due to anti-collision facility
Cell cube 1 is centered around around bridge pier 8, under the active force of tide, the back of the anti-collision facility cell cube 1 can often with
Friction and collision occur for bridge pier 8, and prolonged contact can cause the composite layer 1-1 on 1 surface of anti-collision facility cell cube to occur
It is damaged.Therefore, two pieces of polyethylene tetrafluoro slide plates 2, the polyethylene tetrafluoro are fitted in the composite layer 1-1 front surfaces
Slide plate 2 can be effectively as the first collision body, so polyethylene tetrafluoro slide plate 2 can replace composite layer 1-1 and bridge
Friction and collision occur for pier 8, and anti-collision facility cell cube 1 is protected so as to indirect.The polyethylene tetrafluoro slide plate 2 possesses
Corrosion resistant characteristic, can be impregnated in river water or seawater borough chief's time.In order to further fix polyethylene tetrafluoro slide plate 2,
In the framework of steel reinforcement 1-2 front surfaces equipped with the first built-in fitting 4, first built-in fitting 4 passes through composite wood by bolt
Bed of material 1-1 is fixedly connected with polyethylene tetrafluoro slide plate 2.
As shown in Fig. 1 Fig. 2 and Fig. 3, the framework of steel reinforcement 1-2 left and right ends are equipped with the second built-in fitting 5, and described second is pre-
Embedded part 5 is fixedly connected by locking nut with earrings 3, and there are four earrings 3, the earrings 3 for connection on second built-in fitting 5
On perforate upward, adjacent anti-collision facility cell cube 1 is connected by the earrings 3 by chain 7.Wherein, single reinforcing bar
Skeleton 1-2 is difficult to position around bridge pier 8, easily claps by tide.So the present invention passes through several framework of steel reinforcement 1-2
Chain 7 is connected with each other around bridge pier 8.Because being flexibly connected between anti-collision facility cell cube 1 and anti-collision facility cell cube 1, avoid
The whole anti-collision facility scale of construction is big, rigidity deficiency, the risk easily snapped off under wave and shock.In order to effectively by chain
7 are fixed in anti-collision facility cell cube 1, in the framework of steel reinforcement 1-2 left and right ends equipped with the second built-in fitting 5, described the
Two built-in fittings 5 are fixedly connected by locking nut with earrings 3, and there are four earrings 3, the ears for connection on second built-in fitting 5
Perforate on ring 3 is upward.
To sum up, when ship and anti-collision facility 1 frontal impact of cell cube, 1-1 layers of exterior composite material becomes first
Shape, tearing, while internal closed pore Energy dissipating material 6 is squeezed, on the one hand extend the effect of impact time during this, reduce and hit
Hit power；Further, internal framework of steel reinforcement 1-2 deforms, and stretches and surrenders, and extends the effect of impact time, in the mistake of surrender
Ship kinetic energy is absorbed in journey, reduces impact force.When ship and the grazing of anti-collision facility side, due to anti-collision facility cell cube 1
Smooth outer surface, and surrounding sets fillet, and ship direct of travel is easily made to deflect, takes away most of kinetic energy.Anticollision at this time
1 absorption ship small part kinetic energy of facilities units body, is not subject to big impact force.
Anti-collision facility unit body portion manufacture craft is as follows：
Mold is made, mold is enclosed construction, is divide into upper part and lower part, and leaves charge door, and sets flange plate；
Framework of steel reinforcement 1-2 is placed among mold by welded reinforcement skeleton, is adjusted position, is made framework of steel reinforcement placed in the middle.
Guan Bi mould adds reagent into mold by charge door, covers tightly flange plate, wait energy consumption closed-cell materials 6 into
Type.
Mold is opened, takes out energy consumption closed-cell materials, final framework of steel reinforcement 1-2 and energy consumption closed-cell materials 6 form entirety.
Attached multilayer woven glass fabric is wrapped outside energy consumption 6 body of closed-cell materials, while sets the first built-in fitting 4 and second pre-
Embedded part 5, and pass through vacuum introducing technology and make composite layer 1-1 in outer layer.
Although specific embodiments of the present invention have been described above, those skilled in the art should be appreciated that this
It is merely illustrative of, various changes or modifications can be made to present embodiment, without departing from the principle of the present invention and reality
Matter, protection scope of the present invention are only limited by the claims that follow.
