Further, the caliber size of the opening end of described first wire netting, the second wire netting and described 3rd wire netting, all proportional with the size of concrete maximum aggregate.
Further, the coupling end of described first wire netting, the second wire netting and described 3rd wire netting is to the distance size of opening end, all proportional with the size of concrete maximum aggregate.
Further, the pitch size of the spiral-line of described first wire netting, the second wire netting and described 3rd wire netting, all proportional with the size of concrete maximum aggregate.
It can be symmetrical structure that reinforced metal mesh is split in concrete resistance that above-mentioned bidirectional screw is tubaeform, also can be unsymmetric structure, in actual use, according to the actual needs of working-yard, set the size that each size of reinforced metal mesh is split in the tubaeform concrete resistance of above-mentioned bidirectional screw, therefore, the bore of the opening end of described first wire netting, the second wire netting and described 3rd wire netting is equal or not etc.
In like manner, the coupling end of described first wire netting, the second wire netting and described 3rd wire netting is equal or not etc. to the distance of opening end.
When reinforced metal mesh is split in concrete resistance that the bidirectional screw using the utility model to provide is tubaeform, for the concrete original crack stage, within this stage, after concrete placement, just start to be frozen into knot, in this process, wherein unnecessary moisture loses gradually, cement slurry curing shrinkage, when string stress reaches concrete tensile strength, appear at the crack or pore etc. on slurry and aggregate interface, start to stablize, develop slowly, form a large amount of interface original fracture gradually, also there is the mortar crack of minute quantity simultaneously, be in the concrete in this stage, the fiber needed due to it is predominantly parallel to aggregate limit wall, namely parallel with Interface Crack, therefore, in prior art, the fiber of random distribution does not have action of crack arrest.Compared to prior art, it is a three-dimensional arrangement that reinforced metal mesh is split in concrete resistance that the bidirectional screw that the utility model provides is tubaeform, spiral metal net can wrap up mortar, it is a kind of structure between aggregate and slurry, the shrinkage strain of part of cement mortar can be resisted, bear portion retracts stress, eliminate part interface original fracture, action of crack arrest can be played to the concrete being in the above-mentioned stage.
For the concrete mortar fracture initiation stage, within this stage, along with the increase of load, interface original fracture enters mortar, and disintegration and failure occurs at the interface of sand and hydrated cement paste, thus causes crack to enter the grout of sclerosis.In prior art, the development in crack runs into the obstruction of the fiber of random distribution, and progress of fracture is slowed down, fiber plays the effect that enhancing is split in resistance, and the fiber of random distribution intersects with crack, forms one or several concentrated force by progress of fracture, hinder crack progressing, but hinder effect general.Compared to prior art, the bidirectional screw that the utility model provides is tubaeform, and reinforced metal mesh is split in concrete resistance, is: when interface original fracture extends to spiral metal net scope in the mechanism in this stage, first, spiral metal net intersects with crackle, and formed and hinder, the first step slows down progress of fracture; When crack continues to develop in spiral metal net, because spiral metal net forms confined effect to mortar in net, in net, mortar strength strengthens, and second step slows down progress of fracture; Because progress of fracture is obstructed, there is bifurcated in crack, and some cracks, bifurcated rank, along the less future development of resistance, get around spiral metal net or aggregate, progress of fracture circuit extension, forms the 3rd step and slow down progress of fracture.By the obstruction of above-mentioned three step fractures, inside concrete fracture distribution is more even, has delayed crack cutting through time, and when concrete is in this stage, concrete resistance that described bidirectional screw is tubaeform is split reinforced metal mesh resistance and split enhancing obviously, and toughness increases obviously.
Stablize extension phase for concrete crack, within this stage, load continues to increase, continuation is expanded by crack, and what have stretches into slurry, the formation macroscopic fracture that be combined with each other had, have new crack to produce, there is nonlinearities change in its curves of stress-strain relationship simultaneously.Due to the rapid unstable propagation in crack, macroscopic fracture occurs thereupon and significantly increases, crack progressing must get around fiber and just can further develop, in prior art, intensive Fiber Distribution makes progress of fracture require the expenditure of energy, show as progress of fracture district and occur a concentrated plastic region, but the ductility of this plastic region improves limited.Compared to prior art, the bidirectional screw that the utility model provides is tubaeform, and reinforced metal mesh is split in concrete resistance, in the mechanism in this stage be: due to the existence of spiral metal net, extend progress of fracture circuit, progress of fracture finds balance after getting around and pass through spiral metal net, concrete ultimate strength continues to increase, this balance performance explanation, the process forming macroscopic fracture is tortuous, early stage be not an obvious major fracture, but to be evenly distributed in metal dictyosome or near, to the middle and later periods, this region constantly increases, show as the plastic zone of certain limit, its ductility is not fully exerted.
For the unstable extension phase in concrete crack, within this stage, when load exceedes critical stress, continuation is expanded by crack, polymerization, and mortar crack is sharply increased, even if load remains unchanged, crack, also by unstable propagation, damages.In prior art, in this stage, fiber plays retardation, slows down fracture speed, and the bonding of fiber and sand-cement slurry weakens gradually, break of CFRP or extract, and concrete ductility is promoted limited.Compared to prior art, the bidirectional screw that the utility model provides is tubaeform, and reinforced metal mesh is split in concrete resistance, in the mechanism in this stage be: due to the existence of spiral metal net, and spiral metal net is space structure, enter the unstable extension phase of crackle, this spiral metal net and sand-cement slurry still can have effective adhesive, its distortion rises appreciably, concrete consumed energy slowly develops, and spiral metal net destroys, and ductility is further enhanced.
In sum, in prior art, due to the fiber many employings linear shape used at present, its length is very short, is mixed to after in concrete, and fiber is stressed comparatively single, in concrete setting process, fiber hinders inside concrete crack propagation effect undesirable, and concrete tension, bending resistance, shearing resistance equal strength improve limited, even under some construction environments, have not a particle of raising; In addition, enhancing mechanical mechanism is split based on fiber resistance, when there is macrocrack in concrete, fiber retardance crack occur and development impact not good, elastic modulus of concrete, fatigue resistance, split rear toughness and weather resistance and promote limited, even under some construction environments, its effect promoting concrete performance is very little.Can learn thus, when adopting fiber of the prior art in concrete, the result of use of fiber is poor, and result of use is unstable.Compared to prior art, the bidirectional screw that the utility model provides is tubaeform, and reinforced metal mesh is split in concrete resistance, because it is three-dimensional arrangement, be space structure, in each stage that concrete cracks, the tubaeform design of spiral of wire netting can effectively and aggregate build-in, hinder inside concrete crack propagation effect ideal, concrete tension, bending resistance, shearing resistance equal strength is greatly improved, concrete shock resistance, fatigue resistance, split rear toughness and weather resistance significantly improves, therefore, the bidirectional screw adopting the utility model to provide in concrete is tubaeform, and reinforced metal mesh is split in concrete resistance, substitute the fiber used in prior art, raising for the concrete impact of performance has obvious effect, and result of use is stablized.
