Abstract
The present invention provides a special concrete coarse aggregate, particularly a special concrete coarse aggregate for replacing a concrete coarse aggregate. The coarse aggregate has the structure that convex ribs and grooves are arranged on the wall of a hermetic hollow casing; the hermetic hollow casing is a spherical body, a hemispherical body or other polyhedral bodies, and is preferably a spherical body. Compared with the prior art, the special concrete coarse aggregate of the present invention has the characteristics of reasonable design, simple structure, easy processing, small volume weight, convenient use, etc., and is preferable material of forward purchase pieces for constructing super-high buildings and long-span bridges; therefore, the present invention has good generalization and use value.
Description
1, technical field
The present invention relates to a kind of material of construction, specifically a kind of high strength lightweight concrete crude aggregates 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 invention is to provide a kind of high strength lightweight concrete crude aggregates that replaces traditional coarse aggregate stone.
The objective of the invention is to realize in the following manner, adopt 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 1 is the structural representation of spheroid for high strength lightweight concrete crude aggregates;
Accompanying drawing 2 is hemispheroidal structural representation for high strength lightweight concrete crude aggregates;
Accompanying drawing 3 is polyhedral structural representation for high strength lightweight concrete crude aggregates.
4, description of drawings
Explain below with reference to Figure of description high strength lightweight concrete crude aggregates of the present invention being done.High strength lightweight concrete crude aggregates of the present invention, shown in accompanying drawing 1,2,3, adopting metal or engineering plastics to make airtight hollow thin walled shell 1 replaces stone to make concrete coarse aggregate, the granularity of airtight hollow thin walled shell 1 is 5-100mm, also is processed with fin groove 2 on the wall of airtight hollow thin walled shell 1.
Airtight hollow thin walled shell 1 be shaped as spheroid, hemisphere or polyhedron.Fin groove 2 can replace with boss or shrinkage pool.
5, embodiment
Its processing and fabricating of high strength lightweight concrete crude aggregates of the present invention is very simple and convenient, shown in the by specification accompanying drawing, adopts the metal sheet punching press to make the hollow shell of different shape.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.
High strength lightweight concrete crude aggregates of the present invention is compared with existing technology, have reasonable in design, structure is simple Single, be easy to the characteristics such as processing, unit weight is little, easy to use, be build the super-high buildings thing and Longspan Bridge pre-Purchase the part preferred material. Thereby, have good value for applications.
Claims (3)
1 high strength lightweight concrete crude aggregates, it is characterized in that adopting metal sheet or engineering plastics to make airtight hollow thin walled shell replaces stone to make concrete coarse aggregate, the granularity of airtight hollow thin walled shell is 5-100mm, also is processed with the groove fin on the wall of airtight hollow thin walled shell.
2. high strength lightweight concrete crude aggregates according to claim 1, what it is characterized in that airtight hollow thin walled shell is shaped as spheroid, hemisphere or polyhedron.
3. high strength lightweight concrete crude aggregates according to claim 1 is characterized in that the fin groove replaces with the boss shrinkage pool.
