Abstract

The invention relates to a building material, and particularly relates to a light fly ash multi-row hole self-thermal insulation building block. The technical scheme is that: according to the light fly ash multi-row hole self-thermal insulation building block, through holes are uniformly distributed on a cuboid light fly ash building block. The light fly ash building block is prepared by adopting portland cement as a gelling material, adopting fly ash, crude ash, ceramsite or slag, pumice, perlite or vermiculite, sawdust, polyphenyl particles, building adhesives, humectants and additives as filling materials, diluting and dissolving the mixture with water, mixing, stirring, extruding, and curing; the cross sections of the through holes are rectangular, and the arrangement form of the through holes is multi-section, multi-layer, parallel, and interactive. With the combination of the structure of the multi-row hole self-thermal insulation building block and the light composite fly ash material, the performance of the building block such as heat preservation, light weight, thermal insulation, sound insulation, fire prevention, durability, and the like is greatly improved; traditional clay bricks, aerated blocks and traditional outer wall insulation methods are substituted; and national requirements for building energy saving are fully met.

Description

Many rounds of light flyash heat insulation building block

Technical field

The present invention relates to material of construction, specifically a kind of many rounds of light flyash heat insulation building block (also claiming to lay bricks).

Background technology

At present in building field; Its exterior wall or interior wall adopt the building block masonry structure of (also claiming to lay bricks) usually; It is main that masonry is roughly sintered clay brick or fly ash aerated, not only wastes resource, consumes energy, contaminate environment, exists deficiencies such as insulation, lightweight, heat insulation, sound-proofing properties simultaneously; And the building energy conservation aspect can't reach national requirements; And existing sintered clay brick or fly ash aerated are applied to exterior-wall heat insulation, can't satisfy insulation and the incorporate requirement of building structure, in fire prevention with aspect weather resistance, also exist great hidden.

Summary of the invention

The objective of the invention is the problems referred to above of existing to prior art, a kind of have sharp useless, save energy, low production cost are provided, have insulation, lightweight, heat insulation, sound insulation, fire prevention, competent many rounds of light flyash heat insulation building block simultaneously.

The present invention can reach through following technical scheme:

Many rounds of light flyash heat insulation building block is in the light flyash building block of rectangular parallelepiped, to be evenly equipped with through hole.This light flyash building block is to be gelling material with the silicate cement, with flyash, and cinder slag, haydite or slag, float stone; Perlite or vermiculite, sawdust, granular polystyrene, building glue; Wetting Agent for Printing Inks and additive are filler, and dilute with water is in harmonious proportion, and is formulated through mixing, stirring, extruding and maintenance; Its through hole cross section is a rectangle, and the spread pattern of through hole is the parallel mutual arrangement of multistage, multilayer.

The weight ratio of said each composition of light flyash building block is silicate cement 6-30%; Flyash 10% ~ 40%; Cinder slag 20 ~ 50%; Haydite or slag, float stone 5% ~ 30%; Perlite or vermiculite 0.5% ~ 2%; Sawdust 0.5% ~ 3%; Granular polystyrene 0.1% ~ 0.5%; Building glue 0.02% ~ 0.1%; Wetting Agent for Printing Inks 0.01% ~ 0.1%; Additive 0.01% ~ 0.1%; Surplus is a water; Building glue wherein comprises a kind of of 107,108,801 glue for building, and wetting Agent for Printing Inks is a GP concrete wetting Agent for Printing Inks, and additive comprises that concrete is with in accelerating chemicals, toughener, rust inhibitor, the frostproofer one or more.

Former and later two corresponding opening ends of said through hole have the curved shrinkage cavity structure of an end at least; The spread pattern of its through hole is that one deck is the parallel successively mutual arrangement of half-open discharge hole of complete through hole and individual complete through hole of another layer N-1 and both sides more than the N; N wherein is the integer greater than 1, the curved structure of through-hole side wall.Inwall at the semi-open through hole of both sides is pasted with aluminium foil.

Many rounds heat insulation building block structure of the present invention is to have the rectangular through hole and the vertical block of staggered half through hole, and every round hole has hole wall at interval, is provided with open vertical hole on one side at two end regions of block, and every round hole is staggered.After the inwall of through hole is pasted with aluminium foil, be equivalent to increase the dysphoria with smothery sensation radiating layer.After building by laying bricks or stones, vertically hole is interlaced, has reduced vertical cold bridge, has improved heat insulation effect.After particularly adopting this structure of lightweight composite fly ash material-mix; Effectively reduce the raw material usage quantity, reduced own wt, arranged the thermal resistance that vertical hole has improved masonry more; The less thermal conductivity of starting material in addition; Make it performances such as insulation, lightweight, heat insulation, sound insulation, fire prevention, weather resistance and improve greatly, substituted traditional clay brick, aerated blocks and traditional external wall thermal insulation method, satisfied the building energy conservation requirement of country's " living energy-conservation 65% ", " public energy-conservation 50% " fully.
