Detailed Description
Embodiments of the present invention will now be described with reference to the drawings, wherein like reference numerals represent like elements throughout.
With the economic development and the continuous population growth, the demands of people on various building facilities and the like are increasing. In the aspect of coastal construction engineering, the coastal construction engineering such as coastal highways, cross-sea bridges, offshore platform structures and the like are constructed on a large scale, and the engineering structures face the impacts of driving, sailing, sea waves and the like or are subjected to the short-term or long-term actions of explosion, fatigue load and the like during service. The engineering accidents caused by impact or explosion load are more striking and surprise, and if effective structural protection design is not carried out, the extreme loads can cause accidents such as engineering structural failure, even collapse and the like, so that casualties and huge economic losses are caused. The reinforced concrete structure with the most application at present is difficult to arrange due to the fact that the reinforcement quantity is too high when the reinforced concrete structure resists larger impact or explosion load, and construction difficulty is increased. Moreover, traditional reinforced concrete structures tend to be relatively brittle and not ductile enough, and when subjected to impact and explosion loads, the internal steel bars tend to be difficult to constrain the concrete, so that the concrete is easy to peel, crush and splash, and huge risks are caused to life safety of people.
The invention aims to design a protection system which has small brittleness and large ductility, can greatly exert the ductility of the protection system when being subjected to impact or explosion load, consumes energy in deformation, effectively dissipates the impact or explosion load and improves the protection performance.
As described above, in the embodiment shown in fig. 1, the flexible cable energy-consuming steel-concrete sandwich combined protection system 100 for a coastal building according to the embodiment of the present invention includes:
A steel concrete structure 10, said steel concrete structure 10 comprising: the concrete structure comprises a first layer of steel plate 1, a second layer of steel plate 2 and a concrete layer 3, wherein studs 4 are welded on opposite sides of the first layer of steel plate 1 and the second layer of steel plate 2, one sides of the first layer of steel plate 1 and the second layer of steel plate 2, on which the studs 4 are welded, are oppositely arranged, the concrete layer 3 is formed between the first layer of steel plate 1 and the second layer of steel plate 2, and the studs 4 are coated by the concrete layer 3;
the flexible cable structure 20 is arranged on the back side of the second layer of steel plate 2, and is used for participating in auxiliary energy consumption when the protection system 100 is loaded.
In the embodiment of the present invention, the steel concrete structure 10 and the flexible cable structure 20 are a main energy consumption part and an auxiliary energy consumption part in the protection system of the present invention, respectively, and the steel concrete structure 10 as the main energy consumption part directly participates in energy consumption when receiving impact or explosion load. The steel concrete structure 10 is an excellent protective structure under impact or explosion load. The steel concrete structure 10 is formed by combining a steel plate and an internally filled concrete, wherein studs are welded in the steel plate to serve as shear connectors so as to ensure that the steel and the concrete work cooperatively, and when the steel plate bears impact or explosion load, on one hand, the internally filled concrete can effectively improve bearing capacity, strain capacity and transverse rigidity under the restraint of the steel plate, and meanwhile, the internally filled concrete can effectively prevent the steel plate from buckling prematurely. On the other hand, the steel plate can exert the stretching film effect of the plate, and the energy of impact load is absorbed in a large quantity in a large deformation mode. Moreover, if the explosion load, such as huge energy, actually occurs, the filled concrete is cracked, and the steel plate can also effectively prevent the filled concrete from bursting out, so that innocent casualties are avoided.
And when the impact or explosion load is large, the steel concrete structure 10 will generate a certain deformation, so that the steel concrete structure 10 needs to have a large deformation capability, and when the steel concrete structure 10 generates a large deformation, the flexible cable structure 20 as an auxiliary energy consumption part participates in auxiliary energy consumption. How the flexible cable structure 20 participates in auxiliary energy consumption will be described in detail below.
In one embodiment, referring to fig. 1 and 2, the concrete layer 3 is a rubber modified lightweight concrete layer. When the traditional steel plate-concrete combined structure bears local impact or explosion load, the common concrete has the characteristics of high brittleness and insufficient ductility, so that local punching damage is easy to occur, a large amount of materials often have no bearing capacity and energy consumption capacity, the protection effect in actual engineering is limited, and the material utilization rate is not high. The rubber modified lightweight concrete has larger deformation capacity than common concrete due to more internal gaps, and the energy consumption capacity of the lifting structure is improved by virtue of the light weight, high strength and high strain advantages of the lightweight concrete. In addition, with the development of the automobile industry, the junked tires bring a serious burden to the environment. And because the desulfurization reclaimed rubber production has the problems of low profit, long production flow, high labor intensity, high energy consumption, serious environmental pollution and the like, the desulfurization reclaimed rubber gradually declines, and the waste tires are prepared into rubber powder for recycling, so that the desulfurization reclaimed rubber is applied to the rubber modified concrete admixture, and is an important means for treating the waste tires. The rubber modified lightweight concrete layer absorbs the specific properties of rubber, so that the rubber modified lightweight concrete layer has the following characteristics: the light weight, good sound insulation and heat insulation effects, high crack resistance, wear resistance, deformation performance and energy consumption performance. Meanwhile, the rubber powder is mixed into the lightweight concrete, so that the damping coefficient of the concrete can be effectively improved, and further the impact resistance and antiknock performance of the concrete can be improved. Therefore, the rubber modified lightweight concrete layer can greatly improve the characteristic of good ductility which is not possessed by the common concrete layer.
In one embodiment, referring to fig. 1, the pegs 4 are J-hook pegs, and the J-hook pegs welded to opposite sides of the first layer of steel sheet 1 and the second layer of steel sheet 2 are mutually thickened. The steel concrete structure 10 is formed by combining steel plates and internally filled concrete, J hook-shaped studs are welded inside the first layer of steel plates 1 and the second layer of steel plates 2 and serve as shear connectors, and the J hook-shaped studs welded on the opposite sides of the first layer of steel plates 1 and the second layer of steel plates 2 are mutually thickened together, so that the steel concrete structure 10 can work cooperatively when bearing impact or explosion loads.

In a natural state, when the flexible cable 21 enters the circular clamping hole inside the clamping head 232, the flexible cable 21 is naturally clamped, and the clamping force of the circular clamping hole of the clamping head 232 on the flexible cable 21 is variable, and is related to the extrusion force of the circular truncated cone-shaped hole of the anchoring ring 231 on the clamping head 232, as in the embodiment shown in fig. 6, when the flexible cable 21 is subjected to a leftward pulling force as shown in the drawing, a friction force is generated between the flexible cable 21 and the circular clamping hole of the clamping head 232, the friction force generates a leftward movement tendency of the clamping head 232, and the circular truncated cone-shaped structure of the anchoring ring 231 generates an extrusion force on the clamping head 232, so that the circular clamping force of the circular clamping hole of the clamping head 232 on the flexible cable 21 increases, and the clamping force generates a leftward movement tendency of the flexible cable 21, which is not larger than the leftward movement of the flexible cable 21.

In a preferred embodiment, the arrangement of the flexible cable structure shown in fig. 2 is accomplished using only two flexible cables, transverse and longitudinal, so that the use of excessive anchor rings and clips can be avoided while ensuring a protective effect. When the protection system bears impact load or explosion load such as vehicles, heavy objects, ships and falls, the steel-concrete sandwich structure firstly participates in energy consumption as a main energy consumption part, and as the main energy consumption part is the steel concrete structure, steel plates in the steel concrete structure (namely a first layer of steel plates and a second layer of steel plates 2 can fully exert the stretching film effect of the steel plates, the steel plates can support larger deformation to absorb a large amount of energy of the impact load due to the physical characteristics, and the concrete layer is a rubber modified lightweight concrete layer and can exert larger ductility, so that the steel concrete structure can dissipate huge energy generated by impact or explosion, and therefore, when the steel concrete structure is impacted by smaller general energy, the steel concrete structure is completely enough to dissipate the energy of the impact with smaller general energy, if the energy of the impact or explosion is large enough to cause the steel concrete structure as the main energy consumption part to generate large impact to generate large deformation to dissipate the energy, the large energy impact reaches the auxiliary energy consumption part, namely the back side flexible cable structure of the second layer of steel plates, when the tension force F at two ends of the flexible cable in the arc-shaped metal ring in the decompression ring reaches the starting threshold value, F cr is generated, the flexible cable structure starts to work, the friction among the splayed ring metal pipe, the arc-shaped metal ring and the flexible cable consumes part of impact energy, meanwhile, during the energy consumption process, the splayed ring metal pipe in the decompression ring generates relative motion with the arc-shaped metal ring from stress to yield to the end of stretching, and particularly referring to figures 7 a-7 c, fig. 7a to 7c are schematic views showing the relative movement of the arc-shaped metal ring with respect to the splayed metal tube, first, referring to fig. 7a, fig. 7a is an initial state view of the arc-shaped metal ring 220 being mated with the splayed metal tube 221, where the tension applied to the flexible cable 21 is F, and the diameter of the arc-shaped metal ring 220 is d; fig. 7b shows that the pulling force F at two ends of the flexible cable inside the arc-shaped metal ring reaches the starting threshold F cr, the diameter of the arc-shaped metal ring 220 is d cr, the arc-shaped metal ring 220 and the splayed metal tube 221 move relatively, the flexible cable is pulled out from the arc-shaped metal ring 220, and the diameter of the arc-shaped metal ring 220 is d cr in a gradually decreasing process; fig. 7c shows that the tension F at both ends of the flexible cable inside the arc-shaped metal ring reaches F u, the flexible cable is continuously pulled out from the arc-shaped metal ring 220, the diameter of the arc-shaped metal ring 220 is d u, and the stretching is finished. In addition, when the flexible inhaul cable is under tension, the deformation of the flexible inhaul cable can consume energy, for example, when the flexible inhaul cable is a winding FRP, the flexible inhaul cable can participate in energy consumption through a strain strengthening mode.
Referring to fig. 3 and 6, in the embodiment shown in fig. 3 and 6, the diameter of the circular clamping hole of the clamping head 232 is reduced under the extrusion of the circular truncated cone-shaped hole of the anchoring ring 231, at this time, the clamping force of the clamping head 232 to the flexible cable 21 makes the flexible cable 21 not be pulled out, at this time, the flexible cable 21 inside the arc-shaped metal ring 220 is released for a length Le, so that the whole structure of the protection system has good deformation performance. When bearing impact or explosion load, impact force is transmitted to the flexible cable structure 20 by the steel concrete structure 10, the adjacent decompression rings are connected through the flexible cable 21, the flexible cable 21 connected with the decompression rings drives other flexible cable segments to participate in energy consumption work, the arc-shaped metal rings 220, the fasteners 222 and the back sides of the second-layer steel plates 2 are welded with each other, and the decompression rings far away from the impact action occurrence position drive the steel concrete structure of the welded part to participate in energy consumption, so that the utilization rate of structural materials is high and the integrity is good. Meanwhile, the decompression rings are arranged in the transverse direction and the longitudinal direction at the same time, the flexible inhaul cables are staggered and wound at intervals in the height direction for a certain distance, deformation energy consumption in the transverse direction and the longitudinal direction can be realized, and the protection effect is further improved. Under extreme conditions, the load generated by impact or explosion is huge, the protection system is insufficient to dissipate the huge load, the protection system possibly breaks down, concrete is easy to peel off, broken and splashes, and huge risks are caused for life safety of people, but due to the existence of the flexible cable structure, the flexible cable structure is distributed in the longitudinal and transverse directions, so that concrete splashing can be effectively prevented, and safety accidents are avoided.
In one embodiment, the arc-shaped metal ring is an aluminum metal ring.
In one embodiment, the splayed metal tube is made of steel.
In one embodiment, the flexible inhaul cable is an FRP flexible inhaul cable, and the FRP flexible inhaul cable has the advantages that the FRP flexible inhaul cable is used as the inhaul cable instead of a traditional steel wire rope, so that the steel wire rope can be prevented from rusting and corroding in severe environments such as coasts, and long-term protection effect is affected.
