It can be symmetrical structure that reinforced metal mesh is split in concrete resistance that above-mentioned unidirectional honeycomb is tubaeform, also can be unsymmetric structure, in actual use, according to the actual needs of job site, set the size that each size of reinforced metal mesh is split in the tubaeform concrete resistance of above-mentioned unidirectional honeycomb, therefore, the bore of the openend of described first wire lath is equal or different from the bore of the openend of described second wire lath.
It can be symmetrical structure that reinforced metal mesh is split in concrete resistance that above-mentioned unidirectional honeycomb is tubaeform, also can be unsymmetric structure, in actual use, according to the actual needs of job site, set the size that each size of reinforced metal mesh is split in the tubaeform concrete resistance of above-mentioned unidirectional honeycomb, therefore, the link of described first wire lath is equal or different to the distance of openend with the link of described second wire lath to the distance of openend.
When reinforced metal mesh is split in concrete resistance that the unidirectional honeycomb using the utility model to provide is tubaeform, for the concrete original crack stage, within this stage, after concreting, just start to be frozen into knot, in this process, wherein unnecessary moisture loses gradually, cement slurry curing shrinkage, when shrinkage 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 stereochemical structure that reinforced metal mesh is split in concrete resistance that the unidirectional honeycomb that the utility model provides is tubaeform, honeycomb 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 cement paste of sclerosis.In prior art, the development in crack runs into the obstruction of the fiber of random distribution, and fracture propagation 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 fracture propagation, hinder crack progressing, but hinder effect general.Compared to prior art, the unidirectional honeycomb that the utility model provides is tubaeform, and reinforced metal mesh is split in concrete resistance, is: when interface original fracture extends to honeycomb net scope in the mechanism in this stage, first, honeycomb net intersects with crackle, and formed and hinder, the first step slows down fracture propagation; When crack continues to develop in honeycomb net, because honeycomb net forms confined effect to mortar in net, in net, mortar strength strengthens, and second step slows down fracture propagation; Because fracture propagation is obstructed, there is bifurcated in crack, and some cracks, bifurcated rank, along the less future development of resistance, get around honeycomb net or aggregate, fracture propagation circuit extension, forms the 3rd step and slow down fracture propagation.By the obstruction of above-mentioned three step fractures, inside concrete fractue spacing is more even, has delayed crack cutting through time, and when concrete is in this stage, concrete resistance that described unidirectional honeycomb is tubaeform is split reinforced metal mesh resistance and split enhancing obviously, and toughness increases obviously.
