Abstract

The utility model discloses a concrete composite heat-insulation building brick which is composed of a main body of a building block and surface layers. The main body materials comprise cement, sands and stones, and filling materials in a hollow cavity comprise fly ash. The utility model is characterized in that the main body of the building block forms into a three-hollow shape like the Chinese character 'pin', and the surface layer is in a smooth surface shape. Glue and the fly ash are added in the main body materials, and polystyrene particles, strew powders of crops and foaming particles are added in the filling materials in the hollow cavity. Because the surface layer of the building block is in the smooth surface shape, the thickness is uniform, and the surface layer which is impacted by external force is not easily damaged. If the external surface needs sticking exterior wall bricks or smoothing, a small amount of building materials, such as cement, etc. need to be stuck. Because the gum and the fly ash are added in the main body materials, and the polystyrene particles, the straw powders of farm crops and the foaming particles are added in the filling materials in the hollow cavity, the volume weight of the main body is lightened. Furthermore, because the main body is in a shape like the Chinese character 'pin', the building blocks are arranged in the modes of crossing and correspondence when a wall body is built, the heat-insulation layer is in a bilayer structure, and the effect of heat insulation is ideal.

Description

Concrete composite heat insulation building blocks

Technical field the utility model belongs to the construction material technical field, relates to the building block that a kind of construction wall is used, and particularly relates to a kind of concrete composite heat insulation building blocks.

The concrete heat-insulating block of background technology prior art is made up of two hollow stripping and slicing main bodys and surface layer, and surface layer is concavo-convex or striped splitting shape, and its material is made of cement, sand or stone, stripping and slicing two hollow in the powder filler powdered coal ash thermal insulation material.The concrete heat-insulating block of this structure, capacity is heavier, though have certain insulation effect, because two hollow insulating layer is in same aspect, so heat insulation effect is not very desirable; Again because its surface layer is concavo-convex or striped splitting shape, became uneven is if be subjected to external force collision surface layer rapid wear, if external surface need paste exterior wall tile or floatingly then need to consume a large amount of constructional materialss such as cement.

The summary of the invention the purpose of this utility model provide a kind of light capacity, surface layer thickness evenly, the concrete composite heat insulation building blocks of high insulating effect, to remedy the deficiencies in the prior art.

The utility model concrete composite heat insulation building blocks is made up of building block main body and surface layer, and main material comprises cement, sand and stone, and hollow inner filling material comprises flyash; Its main points are that the building block main body is three hollow articles fonts, and it is smooth planar that surface layer is; For reducing building block main body unit weight, add glue and flyash in the said main material, add granules of polystyrene, crop stalk powder and expanded beads in the said hollow inner filling material.

The utility model building block surface layer is smooth planar, so thickness is even, is subjected to the external force collision surface layer not fragile, if external surface need paste exterior wall tile or floating constructional materials such as a spot of cement of needs gets final product; Owing to add glue and flyash in the main material, add granules of polystyrene, crop stalk powder and expanded beads in the hollow inner filling material, main body unit weight is alleviated greatly; Because main body is three hollow articles fonts, the building block intersection is corresponding when construction wall settles again, and insulation layer is a double-decker, the heat insulation effect ideal.
