Abstract
The utility model provides special concrete coarse aggregate, concretely speaking, is the special concrete coarse aggregate replacing the concrete coarse aggregate. The structure of the coarse aggregate is that a convex rib and a flute are processed on the wall of a closed hollow shell. The closed hollow shell can be a spherical body, a hemispherical body or other polyhedral bodies, and the spherical body is the best. Compared with the prior art, the special concrete coarse aggregate of the utility model is characterized by reasonable design, simple structure, easy processing, little bulk density and convenient usage, which is the preferred material used for building super-high buildings and pre-constructed parts of large-span bridges. Therefore, the utility model has good promotion and usage value.
Description
1, technical field
The utility model relates to a kind of material of construction, specifically a kind of special-purpose coarse aggregate of concrete that replaces concrete coarse aggregate.
2, technical background
As everyone knows, concrete is to add water by cement, sand and coarse aggregate to mix and form, and the fineness ratio of the coarse aggregate that uses is different with the size of prefabricated component, and the granularity of general coarse aggregate is at 5-100mm.The material of building concrete coarse aggregate that prefabricated component uses is the stone of various granularities at present, and the in use existing deficiency of this kind coarse aggregate is that unit weight is big, the needs of incompatible modernized Highrise buildings or Longspan Bridge engineering construction.
3, summary of the invention
The purpose of this utility model provides a kind of special-purpose coarse aggregate of concrete that replaces traditional coarse aggregate stone.
The purpose of this utility model realizes in the following manner, adopts metal or nonmetal hollow shell body to replace stone to make concrete coarse aggregate, can make the unit weight of every cubic meter of concrete reduce more than 1000 kilograms.
Accompanying drawing 3 is polyhedral structural representation for the special-purpose coarse aggregate of concrete.
4, description of drawings
Explain below with reference to Figure of description the special-purpose coarse aggregate of concrete of the present utility model being done.
The special-purpose coarse aggregate of concrete of the present utility model, shown in accompanying drawing 1,2,3, its structure is to be processed with fin groove 2 on the wall of airtight hollow shell 1.Airtight hollow shell 1 is spheroid, hemisphere or other polyhedron, is preferably spheroid.
5, embodiment
Special-purpose its processing and fabricating of coarse aggregate of concrete of the present utility model is very simple and convenient, adopts the metal sheet punching press to make the hollow shell of different shape shown in the by specification accompanying drawing.The effect of on the wall of hollow shell, going out the groove fin be improve the effective surface area of hollow shell and with the firmness of other material.The intensity of steel spherical hollow housing is higher in general.Certainly the hollow shell that uses high-intensity engineering plastics or organic materials injection moulding to make, its erosion resistance and cut down finished cost better than metallic substance.Particular case can be decided by the engineering design requirement.
The special-purpose coarse aggregate of concrete of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to characteristics such as processing, unit weight is little, easy to use, be to build super-high buildings thing and Longspan Bridge forward purchasing part preferred material.Thereby, have good value for applications.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
Claims (2)
1. the special-purpose coarse aggregate of concrete is characterized in that being processed with fin and groove on the wall of airtight hollow shell.
2. the special-purpose coarse aggregate of concrete according to claim 1 is characterized in that airtight hollow shell is spheroid, hemisphere or other polyhedron, is preferably spheroid.
