Abstract
The utility model discloses an improve device of ECC concrete mesobrachium orderliness range, the device includes flourishing appearance bucket, has seted up the through-hole in the bottom of flourishing appearance bucket, has annular circular bead in the peripheral reservation of through-hole, has placed the bottom plate on annular circular bead, and the equipartition has the sieve mesh on the bottom plate, sliding connection has circular clamp plate including, at the top central fixedly connected with handle of circular clamp plate. The utility model discloses utilize cement, mineral admixture, fine aggregate, water, admixture and short-staple to make into mobility ECC concrete, then pour into its flourishing appearance bucket that the bottom equipartition has the sieve mesh, exert certain pressure in flourishing appearance bucket again, like this alright improve fibrous orderly arrangement in the ECC concrete after combing through the sieve mesh, overcome the miscellaneous shortcoming that distributes of short-staple in the ECC concrete.
Description
Technical Field
The utility model relates to an improve device that short fiber orderliness was arranged in ECC concrete belongs to ECC concrete technical field.
Background
The ECC concrete has the advantages of multi-crack cracking, deformation capacity more than 300 times of that of common concrete, strong self-repairing capacity and the like, and is widely applied to buildings and bridge engineering for seismic reinforcement, repair and the like. At present, relevant reports at home and abroad mainly focus on the improvement of fiber selection and ECC toughness, and the related research on how to improve the ordered arrangement of short fibers in ECC concrete is less.
The ECC concrete is formed by uniformly stirring cement, fly ash, sand, an additive and water, and then adding fibers for stirring, so that the distribution of short fibers in the formed ECC concrete is heterodromous and is randomly distributed in all directions. The short fibers mainly improve the tensile strength of ECC concrete, but the distribution of the short fibers is heterodromous, and the distribution of the fibers in the tensile direction is only a part of the distribution, so that the tensile strength of the fibers is inevitably weakened.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides an improve device that short fiber orderliness was arranged in ECC concrete to improve short fiber's orderly distribution in the ECC concrete, reinforcing fiber's tensile effect.
The utility model discloses a constitute like this: the utility model provides an improve device of short fiber orderliness range in ECC concrete, includes flourishing appearance bucket, has seted up the through-hole in the bottom of flourishing appearance bucket, has annular circular bead in the peripheral reservation of through-hole, has placed the bottom plate on annular circular bead, and the equipartition has the sieve mesh on the bottom plate, and sliding connection has circular clamp plate including, at the top central authorities fixedly connected with handle of circular clamp plate.
Further, the bottom plate is in clearance fit with the sample containing barrel, the aperture of each sieve pore is 2mm, 4mm or 6mm, and the selection of the aperture is carried out according to the length and the length of the fiber.
Since the technical scheme is used, the utility model has the advantages of: the utility model discloses pour the ECC concrete into the flourishing appearance bucket that the bottom equipartition has the sieve mesh, exert certain pressure again in to flourishing appearance bucket, like this alright improve fibrous orderly arrangement in the ECC concrete after combing through the sieve mesh, overcome the miscellaneous shortcoming to the distribution of short fiber in the ECC concrete.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals: 1-sample containing barrel, 2-bottom plate, 3-annular shoulder, 4-through hole, 5-sieve pore, 6-circular pressing plate and 7-handle.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is further described in detail with reference to the accompanying drawings and examples.
The embodiment of the utility model provides a: as shown in fig. 1, the utility model discloses an improve device of ECC concrete mesobrachium orderliness range, including flourishing appearance bucket 1, seted up through-hole 4 in the bottom of flourishing appearance bucket 1, have annular circular bead 3 in the peripheral reservation of through-hole 4, placed bottom plate 2 on annular circular bead 3, the equipartition has sieve mesh 5 on bottom plate 2, sliding connection has circular clamp plate 6 including, at the top central authorities fixedly connected with handle 7 of circular clamp plate 6. The bottom plate 2 is in clearance fit with the sample containing barrel 1, and the aperture of the sieve pore 5 is 4 mm.
The utility model discloses a use method includes following step:
firstly, preparing flowing ECC concrete by using cement, mineral admixture, fine aggregate, water, additive and short fiber;
step two, different bottom plates 2 can be selected according to the length of fibers in the ECC concrete; the apertures of the sieve pores 5 are different in different bottom plates 2 and can be divided into three kinds of sieve pores 5, namely the apertures of the sieve pores 5 are 2mm, 4mm or 6 mm; then, placing the selected bottom plate 2 into the bottom of the sample containing barrel 1, and enabling the bottom plate 2 to be erected on the annular shoulder 3;
pouring the ECC concrete prepared in the step one into a sample containing barrel 1, applying pressure into the sample containing barrel 1 through a circular pressing plate 6 to enable the ECC concrete to flow out of the sieve pores 5 on the bottom plate 2, effectively improving the ordered arrangement of fibers in the ECC concrete after being combed through the sieve pores 5, overcoming the defect of heteropical distribution of short fibers in the ECC concrete, and pouring or smearing the ordered ECC concrete.
